da Vinci Surgical System Humour

In the OR last week, looking at the da Vanci Surgical System sitting in the corner …

Wait, what’s that at the base of the device?

Could it be?

An easy button!?!?!

There is even a youtube video explaining how to hack the easy button so that it says what you want. They could make for an interesting moment in the hospital.

Shameless Self Promotion

I did an interview recently with Niall Boyce for The Lancet’s technology section. Full text of the article is now available.

In the picture featured in the piece (and reproduced here), I’m digitizing the surface of the brain with a conoscopic holography sensor. The sensor is optically tracked with a Northern Digital Polaris Spectra so that we can reconstruct the 3D surface of the patient’s brain. The patient is undergoing tumor resection at Vanderbilt University Medical Center.

Vanderbilt Neurosurgery Case To Be Featured on Grey’s Anatomy

Do you love CASblog? Grab our RSS feed or subscribe by email.

Dr. McGirt's Cervical Spine Reconstruction on Model

An upcoming episode of Grey’s Anatomy will feature a depiction of a real-life case of internal decapitation from Vanderbilt University Medical Center. The chin of Judy Kerns was eroding into her clavicle. In simpler terms, Kerns’ head was falling off. According to the Vanderbilt news report, she had some degeneration of bone density and was in involved in a car accident which accelerated her deleterious condition. Eventually, her jaw started rubbing on the clavicle and an open sore developed that wore down to the bone.

Vanderbilt Neurosurgeon Matthew McGirt performed a vertebrectomy and reconstructed the entire cervical spine with titanium implants. The only anatomy left intact were the arteries and nerves in her spinal cord. The joints were fused in the procedure so she is unable to rotate or nod her head.

From Nashville’s Channel 2:

The Grey’s Anatomy episode will air on October 20, 2011 on ABC.

Recently, Dr. Reid Thompson, one of my collaborators, gave a TED talk on the sense of wonder he feels in his neurosurgical practice at Vanderbilt. He also describes how he sees the future of robotic and image-guided neurosurgery (around 10:20). Laser-range scan data from my lab is also shown (around 11:00).

CAOS 2011 in London!

Do you love CASblog? Grab our RSS feed or subscribe by email.

Computer Assisted Orthopaedic Surgery (CAOS) is in London, June 15-18, 2011. CAOS is a great conference for researchers that would like to establish connections with orthopaedic surgeons and equipment manufacturers. If you’re a surgeon looking to break into the field, this conference is a good starting point. The audience at the conference seems to strike a good balance between the newbies and the veterans in the field.

MRI-guided Laser for Brain Cancer Treatment

Do you love CASblog? Grab our RSS feed or subscribe by email.

Surgeons at Washington University have a new tool, the Monteris AutoLITT. From the press release:

“This tool gives us a treatment for patients with tumors that were previously deemed inoperable,” said Dr. Leuthardt, MD. “It offers hope to certain patients who had few or no options before.”

In Wednesday’s procedure, the surgeons drilled a small burr hole about the diameter of a pencil through the patient’s skull, and then used MRI scans to guide the thin laser probe through the brain into the tumor.
