the surgeon excises additional tissue from the surgical site to ensure that no additional cancer cells remain. he greatest benefit of Marginprobe is that we can perform this additional tissue removal during a patient initial surgery,

Marginprobe greatest benefit is that it provides added assurance to both the surgeon and the patient that all cancer cells are removed during the initial surgery. t is critically important to spare patients the additional burden of re-excision procedures

#A robot in mind It a new kind of robot, designed for some of the most delicate operations a surgeon can perform.

his is a robotic system for assisting a surgeon during neurosurgery operations. It has been designed for the insertion of instruments like biopsy probes or electrodes for deep brain stimulation through small holes in the head of the patient.

It a new kind of robot, designed for some of the most delicate operations a surgeon can perform.

and is far steadier than a surgeon hand. And that a big help: o maintain a specific orientation

One of the system innovative features is the feedback from the robot to the surgeon via the hand-held controller.

he surgeon can control the movements of the active robot using an instrument like that,

The robot feedback is amplified to help the surgeon feel his way around the brain. So what kind of operation could be perfomed with this type of robot?

In addition the needle is inserted in tiny millimeter steps so the surgeon can track its position by taking successive MRI scans.

Using CT imaging researchers monitored the healing of a human rib that had been removed partially by a surgeon.

Shen says. e want every surgeon who does cataract surgeries to be able to use this.

patients and surgeons would be really eager to adopt it. The researchers, including Brian Otis, associate professor of electrical engineering and also of Google Inc,

and we hope to transplant him as soon as an organ is available says Jonathan Haft a cardiac surgeon at the University of Michigan.

whose main use case is letting surgeons physically eelanomalies such as tumors in CT SCANS, could also revolutionize everything from advertising to architecture.

Personally I am impressed by the maxillofacial surgeon who is using Mcor 3d printing to create surgical guides,

#High-tech glasses help surgeons see cancer The glasses are designed to make it easy for surgeons to differentiate cancerous cells from healthy cells.

Researchers at the Washington University School of medicine have developed high-tech eyewear that helps surgeons detect cancer cells, which glow blue

The special glasses are designed to make it easy for surgeons to differentiate cancerous cells from healthy cells allowing surgeons to make sure no cancer cells are left during surgery.

A surgeon could potentially ook through his hands to what he is actually operating on, for instance.

surgeons are able to biopsy tumors to diagnose and monitor the state of the disease.

cultivate a network of surgeons who can implant the device and recruit hospitals to offer it.

To date surgeons have implanted Retina Implant prosthetics in 36 patients through two clinical trials over six years.

and surgeons sometimes replace the lens. But now, a team of scientists and ophthalmologists has tested a solution in dogs that may be able to dissolve the cataract right out of the eye lens.

#Mini robot space surgeon to climb inside astronauts It could one day answer the prayers of astronauts who need surgery in deep space.

The miniature surgeon slides into the body through an incision in the belly button. Once inside the abdominal cavity which has been filled with inert gas to make room for it to work the robot can remove an ailing appendix, cut pieces from a diseased colon or repair a perforated gastric ulcer.

The feed relays to a control station, where a human surgeon operates it using joysticks.

Space surgeons Prototypes have performed several dozen procedures in pigs. The team says the next step is to work in human cadavers

Surgeons use this procedure, known as entinel lymph node mapping, to determine the extent of cancer metastasis after removing a tumor.

Davide Zaccagnini a vascular surgeon and program manager for the Science Monks and Technology Leadership Program says he was motivated to join because

Two of their collaborators at MEEI Konstantina Stankovic, an ear surgeon who co-led the study with Chandrakasan,

The techniques surgeons have at their disposal today are not accurate enough to identify all the cells that need to be excised.

Surgeons might be able to use the device in the future to treat other types of brain cancer they say.

and for surgeons to then operate on it. We're now trying to add an extra optical signal

enabling surgeons to better determine which tissue to remove and which to leave. Research by Jeremy Duczynski from the University of WA's School of Chemistry and Biochemistry investigated

It s difficult to convince people that an ACI is their best option says orthopedic surgeon Andreas Gomoll at Brigham and Women s Hospital even though it s a more durable fix than microfracture.

So during many hours of spinal cord surgery surgeons at the hospital replaced part of the cancerous vertebra in his neck with the implant.

It also means surgeons didn need t to use cement or screws to hold it in place as they do manufactured with traditionally implants;

Other companies are Oliver Crispin Robotics Limited (industrial robotics) Â Absolute Robotics Limited (industrial robotics) Armstrong Healthcare Limited (robotics forâ surgeons

or where specialist surgeons are not available. Its also reassuring to know that by the time humans are ready to colonize Mars Robonaut doctors will be there to lend a healing hand d

#IBIS pneumatic keyhole surgery robot potentially 1/10 the cost of Da vinci This is a robot system for keyhole surgery consisting of a master unit operated by the surgeon

and that information is sent to the surgeon master robot. So it can be fed back to the surgeon hand.

Alternatively a large force can be produced by a very lightweight compact unit. An advantage of this system is the robot overall can be made extremely compact.?

Right now wee working with surgeons who are actually using this system and giving us feedback on how to improve it.

In this case we tried to get inspiration from the octopus and put it in the surgeon suite.

Now, a new type of measurement method coupled with a modular implant should allow orthopedic surgeons to precisely calibrate leg length after the operation

orthopedic surgeons currently have no suitable method for precisely measuring leg length before the operation

orthopedic surgeons will be able to measure their patients'leg lengths much more precisely. The Fraunhofer researchers collaborated on the new system with several project partners:

Seven cardiac surgeons at Boston Children Hospital will also test the usefulness of 3-D printed heart models in a clinical study this fall.

In 1880, Dr. Henry Faulds, a Scottish surgeon, published a paper on how fingerprints can be used for identification.

Eye surgeons would make an incision in the cornea and use ultrasound to break down the old lens.

and surgeons have been at the forefront of 3d printed medical applications over the last few years,

To step in and train the surgeons that will perform this surgery is 3d Systems with its Robotix Mentor training module.

Alternatively, we may see surgeons first applying the nanoneedle bandages inside the affected region to promote the healthy integration of these new organs and implants in the body.

physical model that surgeons can use to plan surgery. The models could provide a more intuitive way for surgeons to assess

and prepare for the anatomical idiosyncrasies of individual patients. ur collaborators are convinced that this will make a difference,

This fall, seven cardiac surgeons at Boston Children Hospital will participate in a study intended to evaluate the modelsusefulness.

Inferences from a generic model could obscure the very features that matter most to the surgeon.

Each of seven surgeons will be given data on all 10 patients some probably, more than once. That data will include the raw MRI scans and, on a randomized basis,

the surgeons will draw up surgical plans, which will be compared with documentation of the interventions that were performed on each of the patients.

Surgeons could then graft the scaffold onto the patient's heart, and after a few months the patient would be left with a repaired heart (and no scaffold,

"In addition, from the surgeon perspective, not having to worry about a large piece of metal or hard plastic in the area may make future procedures easier."

Custom-Fit Knee Replacements Dr. Ralph Liebelt is one of the few surgeons in the country to use 3d printed, custom-fit knee replacements.

a research fellow and resident surgeon at the University of Michigan Health System, told Live Science.

Though it is surgeons'current best option, it still isn't that great. The surgery is invasive and destructive.

This provides a literal road map for surgeons to follow, showing which tissue is cancerous and

#Researchers show how new hydrogel can facilitate microsurgery Skillful surgeons can do amazing things in extremely small places,

Surgeons at Salamanca University Hospital reported the man's case and how they made the prosthesis last month in the European Journal of Cardio-Thoracic Surgery.

Surgeons typically use a combination of flat plates, bars and mesh to build an artificial rib cage and sternum for patients.

The 3-D printing technology allowed the surgeons to create an implant that"fitted like glove"in the man's chest, Dr. Jose Aranda

#Glowing Tumor Paint Shows Surgeons Where To Cut Brain surgery is complicated notoriously. Before surgeons go in to remove a tumor,

they study the size and location of the tumor. But once theye in, they have to rely on their fingers

so the surgeons had to remove a piece of the tissue before shining a light on it.

however, instead of trains on a track, the surgeons redirect peripheral nerves in a quadriplegic's arms and hands by connecting healthy nerves to the injured nerves.

"Surgeons at Washington University pioneered nerve-transfer surgery. Developed about 25 years ago by the study's senior author, Susan E. Mackinnon, MD, director of the Division of Plastic and Reconstructive Surgery at the School of medicine,

Since surgeons connect working nerves in the upper arms to a patient's damaged nerves in their arms and hands,

surgeons reroute healthy nerves sitting above the injury site, usually in the shoulders or elbows, to paralyzed nerves in the hand or arm.

"Surgeons often use bone chips or bone powder as a sort of putty during bone reconstruction to help areas of bone re-grow.

#New microscopy technology augments surgeon view for greater accuracy Researchers at the University of Arizona (UA) have developed a prototype of a new microscope technology that could help surgeons work with a greater degree

and on its own lacks the spatial cues that would help the surgeon identify anatomical points of reference.

So the surgeon must visualize how the fluorescence in the NIR image lines up with the respective anatomical structures shown in the bright-field view.

the surgeon then sees the information with his or her own eyes. Pogue said he sees the work being important in advancing the translation of research into clinical practice. here are very few papers on this idea of augmenting the surgical field of view that the surgeon sees,

yet this is a high-interest topic, he said. his article presents a very practical idea and innovative implementation

It also retains the imaging environment familiar to surgeons, including key features of surgical microscopes such as real-time magnification and focus adjustments, camera mounting,

In the past, surgeons could not see the laser beam through the standard stereomicroscope, nor anatomical details in the NIR images.

Surgeons aggressively removing a tumor run the risk of damaging normal brain tissue and impairing the patient brain functions;

and the contrast agent identifying cancerous tissue within the augmented microscope may allow surgeons to remove these challenging tumors more accurately

which could help both surgeons and radiotherapists with more effective treatment. Professor Charlie Swanton, NCRI chair and Cancer Research UK scientist at the Francis Crick Institute, said:

leading transplant surgeons have been meeting with Revivicor ever few months to plan what genes they like to see added next.

or 100 iterations. et surgeons credit the genetically enhanced pigs with some recent successes. Muhammad Mohiuddin,

a transplant surgeon and researcher at the National Heart, Lung, and Blood Institute, in Bethesda, Maryland, says a heart from one of Revivicor pigs lasted two and a half years inside a baboon.

That is because surgeons still need to completely replace a baboon heart with one from these pigs

but lungs are very difficult. ransplant surgeons say one of the largest obstacles they face is the immense cost of carrying out xenotransplant experiments.

#Transplant Surgeons Revive Hearts After Death Transplant surgeons have started using a device that allows them to eanimatehearts from people who have died recently,

In at least 15 cases, surgeons in the United kingdom and Australia say they have used the system to successfully transplant hearts removed from patients after theye died.

surgeons at St vincent Hospital in New south wales described three cases in which they waited as little as two minutes after a person heart stopped before they began removing it.

Without such help, surgeons consider hearts from dead donors too damaged to use. he device is vital.

says Stephen Large, a surgeon at Papworth Hospital in the United kingdom, which has used the system as part of eight heart transplants.

Transplant surgeons recognize two major categories of death. People can be brain dead, or they die

a transplant surgeon at the Massachusetts General Hospital. arm is the way to go with metabolically active tissue.

But surgeons found that hearts that stop naturally often didn start again, or can pump blood,

says Large, the Papworth surgeon. The crisis is particularly severe in the U k, . where handguns and some other firearms are prohibited,

the ethical dilemma is how long surgeons should wait before swooping in to retrieve organs. In the U s.,the accepted standard is five minutes,

although Colorado surgeons in 2008 took hearts from brain-damaged newborns after waiting only 75 seconds.

says that nine months ago surgeons implanted two bunches of silicon electrodes, called Utah arrays, into the volunteer motor cortex.

but some hospital administrators have come to view them as the first must-have robot tech in a health care industry that's bracing for big changes with the imminent arrival of robot cleaners, diagnosticians, surgeons, and nurses."

or local anaesthetic and surgeons cut open the affected artery to remove the build up and then sew the wound up.

which led surgeons at the other hospital to remove it. But the rash persisted and a few years later a rare form of skin cancer known as Marjolin's ulcer developed at the surgical site.

Minimally invasive techniques, also known as"keyhole surgery,"enable surgeons to operate on patients without requiring major incisions.

and even physical strength on the part of the surgeon, has changed barely since the earliest days of endoscopy,"says Timo Cuntz, a member of the Project Group for Automation in Medicine and Biotechnology PAMB in Mannheim, a part of the Fraunhofer Institute for Manufacturing Engineering and Automation IPA.

The cable mechanism transmits the surgeon's hand movements at one end to the tiny instruments at the other extremity of the endoscope.

making it difficult for the surgeon to manipulate the tissue precisely.""The surgeon's work would be made much easier

if it were possible to reduce the friction and increase the power density. Hydraulic instruments are one of the alternatives being considered as a substitute for mechanical transmission based on Bowden cable."

They allow the surgeon to carry out much finer movements, "says the engineer. A plastic tube filled with a sterile,
