Abstract
A surgical stapler that can deliver staples or anchors into both tendon and bone. The staples or anchors releasably engage to the end of a staple rod. The stapler rod includes a butterfly clip on its proximal end, the butterfly clip having two wings or panels and a striking surface between the wings. The stapler is used to secure a biological construct to tendon or bone during arthroscopic surgery. The device includes a stapler handle with an insertable staple rod. The stapler handle drives the staple rod to advance a staple into the bone or tendon.
Claims15
A surgical stapler system comprising:
- a handle having first housing portion and second mating housing portion with an inner longitudinal chamber that extends parallel to the length of the handle;
- a slider block disposed within the inner longitudinal chamber, the slider block including a telescoping tube at a distal end of the slider block, a spring mount positioned within the telescoping tube, at least one engagement tab or groove at a proximal end of the slider block configured to releasably engage a staple rod and at least two upwardly projecting tabs configured to stabilize the slider block against the handle when the slider block is driven forward;
- a spring sized and dimensioned to be positioned over the telescoping tube and spring mount at the distal end of the handle and arranged to bias the slider block toward a distal position after actuation;
- a cannula positioned adjacent to the spring and projecting distally from the distal end of the handle;
- an insertable rod configured to be received within and advanced through the inner longitudinal chamber and the cannula, the rod including an implant holder shaft having a proximal end and a distal end, a clip including at least one panel and a striking face adjacent to the panel, the clip disposed at the proximal end of the implant holder shaft and at least one anchor supported at the distal end of the implant holder shaft;
- and a trocar tip positioned at the distal end of the implant holder shaft and configured to releasably secure the at least one anchor, the trocar tip including a central anvil configured to maintain alignment of the at least one anchor prior to deployment;
- and
- a trigger pivotably mounted to the slider block;
- wherein the trigger is operably coupled to the slider block such that pivoting of the trigger relative to the handle axially advances or retracts the rod within the inner longitudinal chamber of the handle.
A method of implanting a bone or tendon anchor using a surgical stapling system, the method comprising the steps of:
- loading a bone or tendon anchor onto the distal end of a rod, the rod including:
- an implant holder shaft having a proximal end and a distal end, a clip including at least one panel and a striking face adjacent to the panel, the clip disposed at the proximal end of the implant holder shaft and at least one anchor supported at the distal end of the implant holder shaft, and a trocar tip positioned at the distal end of the implant holder shaft and configured to releasably secure the at least one anchor, the trocar tip including a central anvil configured to maintain alignment of the at least one anchor prior to deployment;
- advancing the rod to a forward position within the cannula tube;
- establishing an arthroscopic portal in a patient;
- inserting a driver cannula of the stapling system through the arthroscopic portal;
- positioning the distal tip of the rod and place the anchor at a predetermined patch or construct fixation location;
- pulling the trigger to partially expose the trocar tip to manipulate the patch or construct within the patient;
- retracting the distal tip of the rod;
- pressing the distal tip of the cannula tube against the predetermined fixation location;
- pulling the trigger to exert pressure on the handle to drive the anchor into tissue;
- releasing the trigger and disengage the anchor from the rod;
- compressing the panel of the clip to release the rod from the handle;
- and
- removing the rod from the handle.
