Surgical Instruments

Suction and bipolar cautery are used, together with a set of specialized instruments that aid in minimizing surgical trauma to normal neural tissue. Some of these specialized instruments have become essential for the microsurgical resection of spinal cord tumors.

Ultrasonic Aspirator

The application of the Cavitron ultrasonic aspirator (CUSA) system was a significant advancement in the removal of spinal cord tumors. It uses high-frequency sound waves to fragment the tumor tissue, which is then aspirated by the suction apparatus at the tip of the device. This allows much easier and quicker removal of a bulk of tumor tissue, with less manipulation of the adjacent neural tissue as compared to the suction-cautery technique.


The laser is an excellent surgical adjunct for spinal cord surgery. We prefer the Nd:YAG

Contact Laser™ System (SLT, Montgomeryville, PA) to other available laser technologies. This system has a handpiece and contact probes, and can be used as a microsurgical instrument. The laser is particularly useful as a scalpel to perform the myelotomy, demarcate the glial-tumor interface and remove residual tumor fragments. Firm lesions, such as meningiomas, neurofibromas or rare types of intramedullary tumors, can only be removed with reasonable safety when the laser is available. These lesions cannot be manipulated with the bipolar and scissors because of inevitable manipulation of the adjacent spinal cord tissue, and they are too firm for the CUSA for internal debulking. For the rare spinal cord lipoma, the microsurgical laser is the instrument of choice for vaporization of fat and internal debulking.

The term vaginitis is one that is applied to any inflammation or infection of the vagina, and there are many different conditions that are categorized together under this ‘broad’ heading, including bacterial vaginosis, trichomoniasis and non-infectious vaginitis.
