Abstract
1444838 Cauterization instrument CENTRE DE RECHERCHE INDUSTRIELLE DU QUEBEC 28 June 1974 [4 July 1973] 28899/74 Heading A5R An instrument for laparoscopic tubal cauterization comprises a nylon, optionally-disposable probe 12 attached at one end to a plastics hand grip member 10, a pair of electrically conductive electrodes 14, 16 spaced apart to avoid electrical contact therebetween and having actuatable extremities (14a, 16a) together defining a tube grasping portion, the electrodes being connected to an external power source to allow current discharge between said extremities to cauterize the tube at its grasped area. Flat metallic electrodes 14, 16 are mounted on a nylon insulating separator 26 which is slidably mounted inside a sleeve attached by a flange 22b to an iupper portion of member 10. The circular connector plug 28 with annular peripheral grooves therein is mounted on the end. of separator 26 inside portion 20, the plug engaging a socket 29 mounted in a recess 34 in the upper part of a slider 30 which has a fingerhole 32 to permit its movement in the longitudinal direction of probe 12, the electrodes being sufficiently flexible to space from one another when they emerge from sleeve end 22a. When a button 44 is pushed, conductors 46, 48 cause a relay to supply current to the electrodes whose extremities (14a, 16a) are in offset planes so they do not contact each other during the grasping of a tube. In the embodiment of Fig. 6 (not shown), a spring (52) in portion (20′) biases the electrodes apart to facilitate their easy removal from the cauterized tube and the button (44′) is recessed to avoid accidental operation. In the embodiment of Fig. 7 (not shown), the button is replaced by a foot pedal. The extremities (14a, 16a) may be polytetrafluoroethylene coated to prevent their sticking to the tube and may be shaped as a bird’s beak for cutting the tube which may alternatively be done by a cutter (50) mounted to sleeve end 22a in the embodiment of Fig. 5 (not shown). The sleeve 22 may be thinner and longer for insertion through a channel in an operating laparoscope.
