#Advantages, potential of computer-guided spinal surgery In a series of research studies Cedars-Sinai spinal surgeons show that a new method of computer-guided spine surgery is beneficial for spinal reconstruction
The Cedars-Sinai surgeons highlight the advantages of a spinal navigation technique that uses high-speed computerized tomography (CT) imaging to navigate in and around the spinal column from different angles.
They present their findings in six articles published in the current issue of Neurosurgical Focus an online peer-reviewed journal published by the American Association of Neurological Surgeons.
It allows surgeons to more precisely and accurately place reconstruction screws in the narrow bony corridors of the spine avoiding nerves blood vessels and other critical structures.
which displays them on overhead monitors that allow precise tracking of surgical instruments as surgeons insert screws for reconstruction
Surgeons said the technique is superior to existing methods because of its precision and speed. They point out that even small miscalculations with two-dimensional technology can cause problems that require follow-up operations
The Cedars-Sinai surgeons say they have cut these to nearly zero by using computer-guided methods.
The surgeons said the technology has others applications for treating spinal disorders serving as a tool to remove tumors decompress the spinal column
This approach represents a major leap forward for instrumented spine surgery said Terrence T. Kim MD an orthopedic spine surgeon in the Cedars-Sinai Spine Center and expert in the computer-guided navigation field.
Johnson and Kim as study co-authors are Doniel Drazin MD a senior resident in the Department of Neurosurgery and Robert S. Pashman MD a clinical associate professor and orthopedic spine surgeon at the Cedars

Practicing in a surgeon's studiocurrently surgical robots are controlled by a human operator and do not perform procedures autonomously.
While Lee's robot may never be put to work in an operating room it and other robots like it could one day help researchers to design fully autonomous robotic surgeons.
In addition to teaching the robot to paint autonomously Lee also explored the idea of using his robot as a training tool for surgeons who need practice operating a Da vinci surgical arm.
At the Wake Forest Medical center doctors use replica bodies to help train surgeons to use the Da vinci system Lee said.
These replicas are compared pretty expensive to my robotic arm which cost around $1500. This April Lee will represent Wake Forest at the ACC Meeting of the Minds an event where outstanding undergraduate researchers from each ACC university gather at one member university to present their research either verbally or as a poster.
The surgeons implanted two tiny microelectrode arrays, each with 96 electrodes that could record the electrical activity of single neurons.

#Handheld Device For Surgeons Could Turn off Pain A new handheld tool called the Chimaera will help surgeons find the right nerve with ease by giving them real-time feedback during operations.
This kind of device, its developers claim, will usher in a new age of surgical devices, making delicate nerve procedures easier for surgeons everywhere.
In recent years surgeons have been able to implant devices called neuromodulators that can stop pain
But surgeons have a hard time accessing nerves that are behind the eyes or the face because it's difficult to identify the right one among the jumble,
The Chimaera device helps surgeons identify and access specific nerves. When a surgeon holds the wireless wand-like device near a place where he plans to make an incision,
the Chimaera sends data about that spot to a computer where it is combined with information from a CT SCAN of the patient brain taken previously.
This information is compiled into a single X-ray-like image that the surgeon can see in real time with Google glass
the Chimaera can help the surgeon damage as little as possible on its way to the desired nerve,
where the surgeon can implant the neuromodulator device. Right now these most delicate procedures can only be conducted by a handful of surgeons worldwide, Reuters reports.
But the Chimaera could make neuromodulators so much easier to implant that they could become more commonplace.
what will likely be many devices that give surgeons more feedback during a procedure, which will make surgery easier and more precise o
Orthopedic surgeon and Ossur's director of research and development, Thorvaldur Ingvarsson implanted the sensors in the two patients involved in the trial himself
was open to the idea of participating in a clinical trial to test out a new technology that gives surgeons the ability to visualize cancer cells in real time
surgeons rely on scans taken before the operation to decide how much tissue to remove. He says differentiating between healthy cells
which is why surgeons remove an excess amount of healthy tissue when operating, and even when erring on the side of caution,
"The primary goal of the technology is to make sure that the surgeon does not operate in the blind,
which allows a surgeon wearing specialized glasses to see cancer cells glowing.""What this does is conserve the healthy tissue
enabling surgeons to identify critical structures, such as nerves and blood vessels. This combines with the intraoperative data from Chimaera's sensing technology to guide the surgeon to the precise location of a procedure,
helping to ensure the surgical device stays on a predetermined safe pathway. The real-time data generation is designed to be used in conjunction with optical wearable technology, such as Google glass.
This means a surgeon can literally'see'exactly where they are within the body at any point during an operation.
Once the target nerve has been reached the sensors also let the surgeon know, and the implant can then be deployed down the device.
and make it accessible to a broad cross-section of general surgeons. By doing that we make it accessible to a much, much broader patient population,
while most of today's surgical tools are largely passive, offering surgeons little feedback, Chimaera opens the door to a new generation of neurostimulation implant procedures.
enable more surgeons to carry out complex operations at lower risk and with better results for patients.
While it may be some time before a device like Chimaera is in surgeons'hands, Karger said it could pave the way for wireless pain management for patients using, for example, their mobile phone:"
A surgeon, for instance, will be able to work on a virtual brain physically, with the full tactile experience,

#Scientists invent system to improve effectiveness of cancer surgery With the goal of making it easier for surgeons to detect malignant tissue during surgery
scientists have invented a new imaging system that causes tumors to ight upwhen a hand-held laser is directed at them. surgeon goal during cancer surgery is to remove the tumor,
Mohs and co-authors report on their prototype system that combines a fluorescent dye that localizes in tumors with a real-time imaging system that allows the surgeon to simply view a screen to distinguish between normal tissue and the ightedmalignant tissue.
Current technology allows cancer surgeons to scan tumors prior to surgery with magnetic resonance imaging and other systems.
A surgeon-controlled laser can be directed at any area of interest. In addition an imaging system with three cameras sits above the surgical field.
a surgeon would scan the tumor prior to surgery to determine its boundaries. The tumor would then be removed surgically
"says Dr. Markus Selzner, a transplant surgeon in the Multi-Organ transplant Program at TGH, co-investigator of the clinical trial and the transplant surgeon who performed the donor operation.

It is capable of working 10 times faster and with more accuracy than a surgeon hands when performing intricate procedures.
so that surgeons can compensate for the tissue motion that sometimes makes these surgeries difficult. A stereo camera generates a 3d point cloud,
This allows the surgeon to automate the suturing of small vessels and other microsurgical tasks.
Thanks to this technology, Kidsarm is capable of performing intricate procedures such as the suturing of blood vessels and tissues 10 times faster and with more accuracy than a surgeon hands.
When planning for an invasive procedure, surgeons are limited often to two-dimensional MRI and CT (computerized tomography) images,
the Caltech team collaborated with surgeons at Keck Medicine of USC and the rehabilitation team at Rancho Los Amigos National Rehabilitation Center.
The surgeons implanted a pair of small electrode arrays in two parts of the PPC of a quadriplegic patient.

#Tiny'wrist'to assist needle surgery A tiny flexible wrist component for needle-sized surgical equipment could enable surgeons to perform operations in tiny spaces
which a surgeon would operate remotely, like the Da vinci robot which is used now mainly for abdominal operations such as prostate surgery. he Da vinci uses a wire
the surgeon can move the tip of the needle to the site of surgery with great accuracy.
when the surgeon gets the needle tip where it needs to go. Without a riston the end of the needle, it hard for the the surgeon to cut
or remove tissue, or repair damage. Most microlaproscopy uses sharp-edged rings or heated wires on the end of the needle to scrape
Combined with a pincer on the end of the wrist, this could allow surgeons to make precise cuts
said Webster. e think once we give this tool to surgeons they will find all kinds of applications we haven thought of.
