Abstract
A quick connect mechanism for a medical instrument is provided. The quick connect mechanism includes a post and a mating cup that allows for quick mounting, controlled use, and easy dismounting of medical instruments. A set of post teeth are disposed circumferentially around a body proximate a base of the post and are configured to mate and interlock with a set of cup teeth disposed proximate the cup. The post teeth and cup teeth interlock to restrict rotation of the cup relative to the post and stabilize the medical instrument.
Claims22
A quick connect mechanism of a medical instrument, the mechanism comprising:
- a post body including:
- a base;
- a post extending from the base and having an elongated geometry with a round cross-section that defines a post axis about its center, the post having a distal end;
- and
- a set of post teeth disposed circumferentially about the post axis, the base having a diameter greater than a diameter of an outer surface of the set of post teeth, each tooth in the set of post teeth extending in parallel with the post axis towards the distal end of the post, each tooth in the set of post teeth having lateral edges that define gaps between adjacent teeth, the lateral edges angled relative to the post axis such that a distal end of each tooth is narrower than a base of the tooth, the distal end of the post extending beyond the distal end of each post tooth;
- a cup defining:
- a recess having an elongated geometry with a round cross-section that defines a recess axis about its center, the recess having an inner end and an outer end;
- and
- a set of cup teeth disposed circumferentially about the recess axis, each tooth in the set of cup teeth extending in parallel with the recess axis, each tooth in the set of cup teeth having lateral edges that define gaps between adjacent teeth, the lateral edges angled relative to the recess axis such that a distal end of each tooth is narrower than a base of the tooth,
- wherein one of the post body or the cup is configured to be mounted such that the post axis or recess axis respectively is disposed vertically and the other of the post body or cup is disposed on the medical instrument,
- wherein the recess is configured to mate with the post such that the post axis is aligned with the recess axis and an outer surface of the post maintains contact with an inner surface of the recess in order to mount the medical instrument to the post body,
- wherein the set of cup teeth are configured to mate with the set of post teeth in order to restrict rotation of the cup relative to the post about the recess axis.

A quick connect mechanism of a medical instrument, the mechanism comprising:
- a post body including:
- a base;
- a post extending from the base and having an outer surface that is smooth and forms a cylinder, the post defining a post cylindrical axis about a center of the cylinder, the post having a distal end;
- and
- a set of post teeth disposed proximate an intersection of the post and the base and disposed circumferentially about the post cylindrical axis, wherein an outer surface of the set of post teeth defines a diameter that is larger than a diameter of the cylinder formed by the outer surface of the post, wherein the base defines a diameter greater than a diameter of the outer surface of the set of post teeth, each tooth in the set of post teeth extending in parallel with the post cylindrical axis towards the distal end of the post, each tooth in the set of post teeth having lateral edges that define gaps between adjacent teeth, the lateral edges angled relative to the post cylindrical axis such that a distal end of each tooth is narrower than a base of the tooth, the distal end of the post extending beyond the distal end of each post tooth;
- a cup defining:
- a recess having an inner surface that is smooth and forms a cylinder, the recess defining a recess cylindrical axis about a center of the cylinder, the recess having an inner end and an outer end;
- and
- a set of cup teeth extending from the outer end of the recess and disposed circumferentially about the recess cylindrical axis, wherein an inner surface of the set of cup teeth defines a diameter that is larger than the diameter of the cylinder formed by the outer surface of the post and smaller than the diameter formed by the outer surface of the set of post teeth, each tooth in the set of cup teeth extending in parallel with the recess cylindrical axis away from the outer end of the recess, each tooth in the set of cup teeth having lateral edges that define gaps between adjacent teeth, the lateral edges angled relative to the recess cylindrical axis such that a distal end of each tooth is narrower than a base of the tooth,
- wherein the post body is configured to be mounted such that the post cylindrical axis is disposed vertically,
- wherein the cup is disposed on a medical instrument,
- wherein the recess is configured to mate with the post such that the post cylindrical axis is aligned with the recess cylindrical axis and the outer surface of the post maintains contact with the inner surface of the recess in order to mount the medical instrument to the post body,
- wherein the set of cup teeth are configured to mate with the set of post teeth in order to restrict rotation of the cup relative to the post about the post cylindrical axis.
