Battery-powered hand-held ultrasonic surgical cautery cutting device

摘要

A battery-powered, modular surgical device includes an electrically powered surgical instrument operable to surgically interface with human tissue and a handle assembly connected to the surgical instrument. The handle assembly has a removable hand grip and a handle body. The hand grip is shaped to permit handling of the surgical device by one hand of an operator, has an upper portion and a cordless internal battery assembly that powers the surgical instrument. The internal battery assembly has at least one energy storage cell. The handle body is operable to removably connect at least the upper portion of the hand grip thereto and create an aseptic seal around at least a portion of the hand grip when connected thereto and electrically couple the internal battery assembly of the hand grip to the surgical instrument and thereby power the surgical instrument for interfacing surgically with the human tissue.

主权项

1. A battery-powered, modular surgical device, comprising:
an elongated shaft having a distal end and a proximal end, the elongated shaft comprising an electrically powered surgical end effector at the distal end, the end effector operable to surgically interface with human tissue; an instrument body connected to the proximal end of the elongated shaft, the instrument body having a hand grip dock comprising at least one electrical contact; and a hand grip removably and matingly connected to the hand grip dock such that an aseptic seal is created between the hand grip and the instrument body by the non-threaded mated connection between the hand grip and the hand grip dock, wherein the aseptic seal substantially prevents ingress of contamination between the hand grip and the hand grip dock, the hand grip comprising:
a cordless internal battery assembly powering the end effector; andat least one contact electrically coupling the internal battery assembly to the at least one electrical contact of the hand grip dock.
