Abstract
A surgical apparatus for coagulating and cutting tissue includes a handle assembly and a tool cartridge. The tool cartridge includes electrically conductive movable tools, such as jaws and a blade, for cutting tissue. The jaws and blade each are connected to a transmission to facilitate movement. Multiple sheaths are used to encompass and protect the transmissions. Slidable grips are disposed outside of the sheaths and operatively connected to the transmissions that are disposed within the sheaths. At least one lever is supported by the handle assembly and engagable with the grips to facilitate movement of the grips, and thus, the tools.
Claims23
A surgical apparatus for coagulating and cutting tissue, said apparatus comprising:
- a handle assembly including a housing;
- a tool cartridge at least partially receivable in said housing of said handle assembly;
- said tool cartridge including
- a tool for use in cutting tissue;
- a transmission operatively connected to said tool and longitudinally movable between positions;
- a sheath enclosing at least part of said transmission and defining at least one slot, and
- a grip disposed outside of said sheath and operatively connected to said transmission through said at least one slot;
- and
- said handle assembly including a tool actuation lever operatively engagable to said grip of said tool cartridge such that said grip and said transmission move to actuate said tool in relation to actuation of said tool actuation lever.
A surgical apparatus for coagulating and cutting tissue, said apparatus comprising:
- a tool cartridge including a tool for use in cutting tissue;
- a handle assembly including a housing for supporting said tool cartridge
- said housing defining an opening for accommodating said tool cartridge such that part of said tool cartridge is disposed inside said housing and part of said tool cartridge is disposed outside said housing;
- and
- a gate mechanism for shuttering said opening when the tool cartridge is absent from said handle assembly.
A surgical apparatus for coagulating and cutting tissue of a body, said apparatus comprising:
- a handle assembly having a first lever and a second lever;
- a tool cartridge supported by said handle assembly;
- said tool cartridge including
- a pair of jaws electrically connected to a power source and movable in conjunction with said first lever for grasping the tissue, and
- a blade electrically connected to the power source and movable in conjunction with said second lever between positions;
- said tool cartridge also include a cut-coag switch operatively connected to said second lever for automatically switching between a coagulation mode and a cutting mode as said blade is moved between positions.
A surgical apparatus for coagulating and cutting tissue, said apparatus comprising:
- a handle assembly having a first lever and a second lever;
- a tool cartridge supported by said handle assembly, said tool cartridge including
- a pair of jaws movable in conjunction with said first lever for grasping the tissue and electrically connected to a power source, and
- a blade electrically connected to the power source and movable in conjunction with said second lever between positions,
- wherein said tool cartridge is fully rotatable while maintaining mechanical control of said tool and electrical connection between said tool and said power source at any position of rotation;
- an identification chip in communication with the power source for providing identification data regarding said tool cartridge to the power source;
- a lever locking assembly operatively connected to said first lever for securing said first lever and said jaws in position;
- a conductive pad positionable on the body and electrically connected to the power source;
- and
- a switch supported by said handle assembly for switching between a bipolar mode, wherein electric current is conducted from said blade, through the tissue, and to said jaws, and a monopolar mode, wherein electric current is conducted from said blade, through said tissue, and to said conductive pad;
