Medical instrument and method of performing a surgical procedure with the medical instrument

摘要

A medical instrument having an elongate frame with proximal and distal ends. An operating assembly is at a proximal region of the frame with a working assembly at a distal region of the frame. The working assembly has a tip with a leading free end to be engaged with a human body at an operation site. The working assembly has at least one cautery component that: a) contacts a human body at the cutting location; and b) is operable to generate a current that alters a contacted portion of the human body at the cutting location. An insulating material is located at least one of: i) at the leading free end; and ii) between the at least one cautery component and the leading free end so that current does not conduct from the at least one cautery component to body tissue during a medical procedure.

主权项

1. A medical instrument comprising:
an elongate frame with proximal and distal ends spaced in a lengthwise direction along a central axis of the frame; an operating assembly at a proximal region of the frame; and a working assembly at a distal region of the frame, the working assembly comprising a tip with a leading free end to be engaged with a human body at an operation site, the working assembly comprising at least one cautery component that: a) contacts a human body part at the cutting location; and b) is operable to generate a current that alters a contacted portion of the human body part at the cutting location, wherein an insulating material that is not electrically conductive is located at least one of: i) at the leading free end; and ii) between the at least one cautery component and the leading free end so that current does not conduct from the at least one cautery component to the leading free end to human body tissue during a medical procedure, wherein the tip defines in conjunction with a part of the elongate frame a “J” shape.
