Integra LifeSciences. has filed a patent for a cannula system and method designed for accessing a blood mass in the brain. The system includes a camera mounted on the cannula’s proximal end, allowing surgeons to view the surgical field while minimizing obstruction. The method involves inserting the cannula with an obturator, removing the obturator, and positioning the camera assembly to obtain images of the surgical field through the lumen.

A recently filed patent (Publication Number: US20230414090A1) outlines a method for accessing and viewing a surgical field within the brain using a cannula system equipped with a camera assembly. The method involves inserting the cannula with an obturator into the patient's brain, removing the obturator to provide access and visibility for the surgical field, and positioning the camera assembly at the proximal end of the cannula to obtain images through the lumen. The images can be transmitted to a display for viewing, and surgical instruments can be passed through the cannula while the camera assembly is in place.

Additionally, the patent claims specify the placement of the prism within the cannula system, with the prism overhanging the lumen by no more than about 15% or 25% of the inside diameter. This design allows for optimal visualization of the surgical field while maintaining space for the passage of surgical instruments. The method outlined in the patent aims to improve the efficiency and accuracy of accessing and viewing the brain's surgical field, potentially enhancing surgical outcomes and patient care in neurosurgical procedures.
