Modified 0.8 mm-tipped Laparoscopic Dissecting Clamps used to Aid in Cavernous Nerve Preservation During Nerve-Sparing Laparoscopic Radical Prostatectomy

Laparoscopic radical prostatectomy has recently been proposed as a less invasive technique as compared to conventional open radical prostatectomy for the surgical management of prostate cancer. Preservation of the cavernous nerves during radical prostatectomy is a delicate surgical technique that is crucial in reducing the incidence of postoperative impotence in men suffering from prostate cancer. In efforts to refine the laparoscopic instrumentation to replicate nerve-sparing technique in open surgery, finer-tipped dissecting instrumentation is needed. This invention is a modification of pre-existing laparoscopic instrumentation involving modifying the tip design to a right-angled and curved dissector. Refining the tip allows for finer and more meticulous dissection of the nerve bundles surrounding the lateral aspects of the prostate and thus aids in preservation of the cavernous nerves. Description (Set) Proposed Use (Set) The use of these modified instruments would be primarily for nerve-sparing laparoscopic prostatectomy, but could also be extended to other laparoscopic procedures in urology, general surgery and gynecology, that is any laparoscopic procedure that requires fine dissection of delicate tissues.
