Abstract
Disclosed herein is a medical device. The medical device includes a blade tube section, a solenoid, and a mechanical arrangement. The blade tube section includes an outer blade tube, an inner blade tube, and a cutting window at a distal end of the blade tube section. The solenoid is offset from a central axis of the blade tube section. The mechanical arrangement is between the inner blade tube and the solenoid.
Claims17
A medical device comprising:
- a blade tube section comprising an outer blade tube, an inner blade tube, and a cutting window at a distal end of the blade tube section;
- a solenoid offset from a central axis of the blade tube section;
- and
- a mechanical arrangement between the inner blade tube and the solenoid, the mechanical arrangement including:
- a collar fixedly connected to the inner blade tube;
- and
- a lever member extending along a longitudinal axis and connected to the inner blade tube and the solenoid, the lever member including a first end with a first closed-ended elongated opening circumferentially surrounding a first pin, and a second end with a second closed-ended elongated opening circumferentially surrounding a second pin, wherein the lever member is rotatable about the first and second closed-ended elongated openings and the respective first and second pins to transfer solenoid actuation to the inner blade tube;
- wherein one of the first pin or the second pin is fixedly mounted to a housing of the medical device.
