Abstract
A cannula includes an elongated body having a proximal end, a distal end, and a longitudinal axis extending therebetween, a first surface configured for passage of a surgical instrument along the first surface, and a second surface opposite the first surface. A passageway extends along the second surface, which is configured for passage of a suture. An eyelet is at least partially defined through the second surface at the distal end of the body for receiving the suture at the distal end.
Claims17
A cannula comprising:
- an elongated body having a proximal end, a distal end, and a longitudinal axis extending therebetween, a first surface configured for passage of a surgical instrument along the first surface, and a second surface opposite the first surface;
- a passageway extending along the second surface, the passageway configured for passage of a suture;
- an eyelet at least partially defined through the second surface at the distal end of the body for receiving the suture at the distal end;
- and
- a proximal securing component defined at the proximal end of the elongated body, wherein the proximal securing component is configured to secure limbs of the suture to the elongated body via a locking component, and wherein the locking component is slidably configured along the second surface to further secure the suture.
A method for implanting a surgical device, comprising:
- securing a suture to a tissue in a joint space;
- threading the suture through a cannula to form a cannula system, the cannula system comprising:
- an elongated body having a proximal end, a distal end, and a longitudinal axis extending therebetween, a first surface configured for passage of a surgical instrument along the first surface, and a second surface opposite the first surface;
- a passageway extending along the second surface, the passageway configured for passage of the suture;
- an eyelet at least partially defined through the second surface at the distal end of the body for passage of the suture through the distal end of the elongated body;
- and
- one or more securing members against the second surface for securing limbs of the suture passed through the passageway and passed around the distal end
- a proximal securing component defined at the proximal end of the elongated body, wherein the proximal securing component is configured to secure limbs of the suture to the elongated body via a locking component, and wherein the locking component is slidably configured along the second surface to further secure the suture;
- and
- moving the cannula along the suture such that the distal end of the elongated body enters the joint space.
