    摘要： The bipolar modular forceps assembly is a disposable electrosurgical device utilized with an RF voltage supply to weld soft tissue to prevent bleeding when cut or excised. The device consists of two modularly constructed arms arranged in scissor configuration that clamp when the arms are apart and open when the arms are squeezed together. The wires enter from the rear of the device, behind the digit insertion of the upper arm, and run through the interior of the upper arm before reaching the pivot point. From the pivot joint, one wire continues to the bottom jaw and the other wire wraps around the pin bushing in the pivot joint and proceeds to the top jaw. At all times the wires are fully insulated by the insulative cover with the only exposed wire occurring where they enter the device. The bipolar voltage of each wire is transferred to an electrode on each jaw. The electrodes are insulated from surrounding tissue by the insulative jaw, which contains visible markings showing the beginning, middle and end of the electrode. Both the insulative jaw and the electrode are interchangeable and made from moldable material to allow for different sizes and shapes. When no voltage is applied the tool can be used as a blunt dissector.

    摘要： An improved surgical stapler having first and second pivotally interconnected structural members each including a handle portion and a jaw portion. The structural members are pivotally movable between a closed position wherein their jaw portions are in a closely spaced relationship to an open position wherein their jaw portions are spaced apart a substantial distance. A locking member is pivotally connected to one of the structural members for pivotal movement between a first position wherein the locking member is generally aligned with the structural member and a second position wherein the free end of the locking member is spaced apart from the outboard end of the structural member. When actuated, the locking member functions to forcefully move the structural members toward a closed position so that the tissue to be stapled can be securely clamped between the jaw portions of the instrument. A staple cartridge of novel design is removably connected to one of the first and second structural members and contains a plurality of staples for stapling together tissue disposed between the jaw portions of the instrument. A novel jaw stabilizing element is provided either on the staple cartridge or on the disposable anvil of the device for insuring proper spacing between the handle portions of the instrument and in this way functions to maintain optimum jaw closure for every tissue thickness by restricting the undesirable bending of the handle portions as the tissue to be stapled is compressed between the jaw portions.
