Abstract
Medical devices including a housing, an actuator, a body having a passageway extending through the body, a drive shaft extending through the passageway, and a clip coupled to the body and the drive shaft to fix the body relative to the drive shaft. The medical device further including features to couple the clip to at least one of the body and/or the drive shaft such that back out of the clip is inhibited.
Claims20
A motion transfer assembly for a forceps, the assembly comprising:
- a body having a passageway extending through the body;
- a drive shaft having a slot, the drive shaft extending through the passageway;
- a biasing element having an inner diameter positioned around the body;
- and
- a clip positioned to apply a compression force to the biasing element, the clip including a protrusion on a face abutting the biasing element,
- wherein:
- the clip is aligned with the slot;
- the protrusion extends out of a distal end surface of the clip and within the inner diameter of the biasing element;
- and
- the body is configured to move a y relative to the clip and the drive shaft.

A motion transfer assembly for a forceps, comprising:
- a frame;
- an actuator;
- a body including a passageway extending through the body, the body configured to receive a force from the actuator;
- a drive shaft extending through the passageway and coupled to the frame;
- and
- a clip coupled to the body and the drive shaft,
- wherein:
- the clip is coupled to one of the body and the drive shaft by a resilient joint between the clip and the drive shaft that deforms during placement of the clip, returns to position when the clip is in place, and prevents lateral dislodgment of the clip;
- and
- the body is configured to move linearly relative to the clip and the drive shaft.
7 more elements
A motion transfer assembly for a forceps, the assembly comprising:
- a body having a passageway extending through the body;
- a drive shaft extending through the passageway, wherein the drive shaft is slidable with respect to the body;
- a biasing element having an inner diameter, the biasing element positioned around the body;
- and
- a clip longitudinally and radially constrained to the drive shaft and longitudinally movable relative to the body, the clip positioned to apply a compression force to the biasing element, wherein the clip is coupled to one of the body and the drive shaft, and wherein one or more of the clip, the body and the drive shaft include a retention device that interfaces with one or more of the clip, the body and the drive shaft to prevent lateral dislodgement of the clip relative to the body and the drive shaft.
