Abstract:
A surgical suturing device having an axis extending between a proximal end and a distal end is operable to move a suture through body tissue. A handle assembly is coupled to an elongated shaft having a hollow configuration. An actuating rod is disposed to extend between the handle assembly and the shaft. A needle assembly at the distal end of the actuating rod is movable with the actuating rod between an extended state and a retracted state. Bifurcated portions of the needle assembly define a suture slot, the bifurcated portions have a proximate relationship when the needle assembly is in the retracted state and having a separated relationship when the needle assembly is in the extended state. The needle assembly is biased to the retracted state and the bifurcated portions are biased to the separated relationship. A handle assembly is operable to move the needle assembly between a free suture state and a captured suture state. In an associated method of use, the needle is bifurcated to form at least one pair of arms to finding a suture slot.
Abstract:
A suture anchor (e.g. 100) for knotlessly securing nearby tissue to bone is formed from an anchor body (e.g. 101/102) that includes a mechanism for being securely anchored to the bone, an elongated suture puller (e.g. 122) extending through the anchor body with a proximal end for being pulled in a proximal direction by a surgeon and a distal end (e.g. 125) with a suitable mechanism for engaging suture (e.g. 127), suture (e.g. 132) carried by the engaging mechanism (e.g. 127) at the distal end (e.g. 125) of the elongated suture puller (e.g. 122), and a suture locking mechanism (e.g. 110) that substantially prevents the suture (e.g. 122) from moving in at least a first direction after being pulled into and through the anchor body (e.g. 101/102) by the elongated suture puller (e.g. 122).
Abstract:
Deployment systems (220) for deploying a bone fixation device are disclosed herein. One embodiment of a deployment system (220) includes a syringe-shaped body (222) configured to provide proximal traction to a bone fixation device in response to a compressive force between a finger grip (230) and a plunger (228) adapted to be engaged by the heel of a clinician's hand. The device (220) may include a collet (250) for gripping a proximal pin of a fixation device. The deployment device (220) may also include a tool (260) that includes an elongate body with a distal tip (266) adapted to rotationally engage a bone fixation device in order to axially rotate the fixation device.
Abstract:
A tool (200) for inserting a bone fixation device (32) is provided. The tool (200) generally includes an elongate outer body (210) and an elongate inner body (250), each having a proximal end (212), a distal end (214), and a longitudinal axis. The tool (200) typically includes a pin-receiving portion (304) at the distal end (214) of the outer body (210) for receiving a proximal pin (26) of a bone fixation device (32). The tool (200) may further include first and second levers (230) pivotally mounted to the inner body (250) at respective pivot axes (236), and each of the levers (230) having a gripping portion (234). The levers (230) preferably include finger engagement portions, wire-gripping portions (232), and are preferably configured to be axially movable relative to the outer body (210). The levers (230) are generally configured such that a proximal force on the finger engagement portions (232) relative to the outer body (210) will cause the gripping portions (234) to close and to move proximally such that a guidewire (150) of a bone fixation device placed between the wire-gripping portions (234) may be gripped and pulled proximally.
