Definitions

  • 08/136,426 the full disclosure of which is incorporated herein by reference, describes an exemplary resection method and device including a rotating cutting head which chops resected tissue into fragments, thereby facilitating the evacuation of resected tissue through the electrosurgical probe.
  • U.S. Patent Application Serial No. 08/322,680 which is also incorporated herein by reference, provides resection methods and devices including both a rotating chopping mechanism and an electrosurgical cutting wire.
  • the electrosurgical cutting wire is particularly well-suited for removal of strips of tissue from the uterus, prostate, or other internal body cavities.
  • the rotating chopping mechanism severs the strips of removed tissue into tissue fragments, allowing the electrosurgical cutting wire and rotating chopping mechanisms to be independently optimized for these two distinct cutting operations.
  • irrigation supply 41 comprises a standard irrigation supply bag suspended above the surgical site to provide a constant pressure gravity feed, allowing distension pressure to be varied simply by changing the height of the irrigation supply.
  • a valve or controlled flow pump may be used to supply irrigation fluid.

Closed end tube 85 slides over the distal end of shaft 16 with a friction fit, the closed end ensuring proper axial alignment with the shaft. Arms 87 supporting roller 23 are affixed to the outer surface of the closed end tube.
  • a preferred mounting clip 91 is formed from tubing which slides over the end of the shaft with a friction fit, a stop tab 93 ensuring axial alignment. Preferred clip 91 also has an upper tab folded over roughly 180° to form a rotational alignment key 95.

Abstract

L'invention porte sur un dispositif de résection de tissus comportant un arbre (22), un élément tranchant (18) jouxtant l'ouverture, et un mécanisme de découpage placé dans la lumière de l'arbre. Une surface électroconductrice (23) proche de l'élément tranchant (18) sert à appliquer une énergie à des fins de coagulation ou d'ablation à la surface des tissus restants. De préférence l'élément tranchant (18) comprendra un fil électrochirurgical transversal de découpe, et la surface conductrice (23), un rouleau aligné avec le fil pour que, lorsque le fil détache une bande de tissu, à l'extrémité proximale, ladite bande soit aspirée par l'ouverture tandis que le rouleau cautérise tout vaisseau sanguin ouvert.
