    摘要： A method for removing a polyp from inside a patient, comprises the steps of inserting an endoscopic insertion member into a patient, ejecting a cauterization loop from the insertion member, and maneuvering the insertion member and the cauterization loop from outside the patient to place the cauterization loop over a polyp inside the patient. A web member is ejected also from the endoscopic insertion member and is opened from a collapsed configuration to a substantially cup shaped opened configuration having a concave inner surface. The endoscope insertion member and the opened web member are maniipulated from outside the patient to juxtapose the concave inner surface of the web with the polyp, whereupon suction is applied to the web member to form a negative pressure zone between the web member and the polyp, thereby attaching the web member to the polyp in a vacuum seal. Then electrical current is conducted to the cauterization loop to sever the polyp from the patient. The web entrains the severed polyp for removal from the patient.

    摘要： A procedure for endoscopically removing a polyp utilizes an elongate tubular member having a cup-shaped web member at a distal end portion and an electrically conductive cauterization loop inserted through the tubular member. Upon insertion of an endoscope assembly into a patient, the distal end portion of the tubular member and the cauterization loop are ejected from the distal end of the biopsy channel of the endoscope assembly. Upon a subsequent opening of the cauterization loop, the cauterization loop is placed over a polyp to be removed, the web member is then opened and suction is applied through the tubular member to entrain the polyp to the web member. Electrical current is conducted to the cauterization loop to sever the polyp from the patient, and the loop is closed. The severed polyp is held in the web member by suction and is subsequently removed from the patient.

    摘要： A medical instrument including a cautery portion for use in performing an anterior or posterior capsulotomy during extracapsular cataract extraction surgery. A substantially rigid stem portion is connected between the cautery portion and a handle portion, and is provided with bends to facilitate maneuverability of the cautery portion and to avoid substantial interference with the surgical field of vision by the handle portion. An electrical path is defined through the handle portion and stem portion to the cautery portion so as to permit electrical current to be supplied to the cautery portion from an electrical apparatus which generates a radio frequency current. The cautery portion, as supplied with radio frequency current, becomes heated when in contact with an eye lens capsule so as to instantaneously and uniformly sear a peripheral extent of a portion of the lens capsule to be removed during surgery.

    摘要： A disposable hand-held portable cautery powered by selfcontained energizers or batteries for energizing an electrode heating tip which is mounted in an insulating tube provided with a removable protective cap or cover encompassing the heating tip and the upper end of the tube, and the tube is further provided with a simple depressible latching or locking switch button on the tube, so that a portion of the button will frictionally overlie the adjacent end portion of the cap assembled thereon to thus prevent energization of the heating tip while the tube and cap are assembled.
