Abstract
The suture passer includes a body, from which two mechanisms protrude: a hollow needle through which a suture is guided, the suture exiting at the surgical site; and a sliding hollow tube with a distal opening, with a pincer/clamp/jaws held within the sliding hollow tube. The two primary parts of the suture passer are the hollow needle and the retrieval member.
Claims20
A suture passer for arthroscopic surgery comprising:
- a body;
- a hollow needle affixed to the body;
- a retrieval mechanism including:
- a hollow tube;
- the hollow tube sliding with respect to the body;
- the hollow tube having a proximal end and a distal end;
- a connecting rod;
- the connecting rod sliding within the hollow tube;
- clamping jaws;
- the clamping jaws at a first end of the connecting rod;
- the clamping jaws closed when partially surrounded by the hollow tube;
- the clamping jaws open when outside the hollow tube;
- whereby the hollow tube acts to close the clamping jaws by partially surrounding the clamping jaws;
- whereby a suture may pass through the hollow needle to exit at a surgical site, where the clamping jaws may grasp and retrieve the suture.

A suture passer comprising:
- a hollow needle;
- a hollow tube;
- a connecting rod;
- a pair of jaws;
- the pair of jaws attached via a hinge to an end of the connecting rod;
- the pair of jaws, in the absence of an outside force, moving to an open and separated position;
- a body;
- the hollow needle affixed to the body;
- the hollow tube sliding with respect to the body;
- outward motion of the hollow tube, with respect to the connecting rod, surrounding the jaws and causing the jaws to close;
- inward motion of the hollow tube, with respect to the connecting rod, uncovering the jaws and allowing the jaws to open;
- whereby to pass a suture through a surgical site, a user passes a suture through the hollow needle, extending and retracting the hollow tube and pair of jaws to grasp and retrieve the suture.
9 more elements
A suture passer device comprising:
- a hollow needle for passing a suture through an incision;
- a suture retriever parallel to the hollow needle;
- the suture retriever including a connecting rod sliding within a hollow tube;
- a set of jaws attached to a distal end of the connecting rod via a hinge;
- the hollow tube able to partially surround the set of jaws;
- the jaws in a closed position when partially enclosed by the hollow tube;
- the jaws in an open position when free of the hollow tube;
- whereby the hollow needle passes a suture within the path of the set of jaws, the set of jaws used to grip and retrieve the suture.
