Abstract
A single-fire clip applier with disposable jaws and re-usable handles is provided. The first jaw member is coupled to a second jaw member by a connector spring. The connector spring biases the jaws to an open at rest position. The jaws are releasably mountable to a post on the handles. Actuation of the handles produces a corresponding actuation of the jaws. After use, the jaws may be disposed and the handles re-sterilized. Different sized jaws for different sized clips may be used with one common re-usable handle.
Claims16
A surgical instrument for applying a surgical clip comprising:
- a disposable first jaw member having a proximal end, a distal end, and a first raised platform having a first slot extending generally longitudinally along an outer lateral surface of the first raised platform and a first channel extending generally longitudinally along an inner lateral surface of the first raised platform, the first channel including a first opening;
- a disposable second jaw member having a proximal end, a distal end, and a second raised platform having a second slot extending generally longitudinally along an outer lateral surface of the second raised platform and a second channel extending generally longitudinally along an inner lateral surface of the second raised platform, the second channel including a second opening;
- and
- a connector spring releasably mounted to the first and second raised platform and having a first leg and a second leg, the first leg slidably coupled to the slot of the first raised platform and the second leg slidably coupled to the slot of the second raised platform, the connector spring biasing the proximal end of the first and second jaw members together and the distal end of the first and second jaw members apart, and wherein the first and second openings are arranged to receive a post extending from a handle about which the first and second jaw members are rotatable with respect to one another.
A surgical instrument for applying a surgical clip comprising:
- a disposable first jaw member having a proximal end, a distal end, and a first raised platform having a first slot extending lengthwise along the first raised platform;
- a disposable second jaw member having a proximal end, a distal end, and a second raised platform having a second slot extending lengthwise along the second raised platform;
- a connector spring releasably mounted to the first and second raised platform and having a first leg and a second leg, the first leg slidably coupled to the slot of the first raised platform and the second leg slidably coupled to the slot of the second raised platform, the connector spring biasing the proximal end of the first and second jaw members together and the distal end of the first and second jaw members apart;
- a first channel extending from the proximal end of the first jaw member tapered on one end and having an opening on the other end;
- and
- a second channel extending from the proximal end of the second jaw member tapered on one end and having an opening on the other end, wherein the openings of the first and second channels are arranged to receive a post extending from a handle about which the first and second jaw members are rotatable with respect to one another.
