Abstract: Endoscopic surgical instruments in which provision is made for a locking device for a depth gauge or knife and sleeve arrangement which is adapted to be positioned on an endoscope, which provides for latching attachment thereto, and includes stop structure so as to enable the insertion thereof into a slotted cannula to a predetermined depth.

Abstract: Method of implementing endoscopic surgical procedures on a patient, and more particularly, a novel and unique technique of performing uniportal surgical entries. Moreover, also disclosed is a unique endoscopic surgical instrument including a unique cutting device adapted to be employed in the implementation of the foregoing methods of endoscopically effecting the uniportal carpal tunnel release. This surgical procedure only requires the formation of a single and relatively small entry portal or incision in the patient, resulting in minimum discomfort.

Abstract: A method of implementing an endoscopic surgical procedure on a patient, and more particularly, a novel and unique technique of performing a uniportal palmar subligmentous endoscopic carpal tunnel release. Moreover, also disclosed is a unique endoscopic surgical instrument adapted to be employed in the implementation of the foregoing method of endoscopically effecting the carpal tunnel release. This surgical procedure only requires the formation of a single and relatively small entry portal or incision in the palm proximate the distal side of the flexor retinaculum, thereby reducing any postoperative symptoms of the patient with only a cosmetically appealing scar formed on the palm, while eliminating the need for a second portal or incision proximate the wrist of the patient.
