Abstract

This disclosure details a surgical device configured to deliver multiple implants or tools, including corresponding techniques, assemblies, systems, and methods, for using the surgical device. A surgical device according to an exemplary aspect of the present disclosure includes, among other things, a main handle, a main shaft, an inserter partially within the main shaft, and an implant adjacent a distal end of the inserter. The surgical device is configured such that the implant is moveable from a retracted position within the main shaft to an intermediate position within the main shaft by distal movement of the inserter relative to the main handle. Further, the surgical device is configured such that the implant is moveable from the intermediate position to a deployed position distal of the main shaft by relative movement of the main shaft and the main handle.

15 . The surgical device as recited in claim 11 , wherein the surgical device is fully cannulated such that a drill bit is able to pass through an entire length of the surgical device without interfering with the at least one inserter.
16 . The surgical device as recited in claim 11 , further comprising a bone-preparing tool positioned at least partially within the bore adjacent the at least one inserter.
17 . A surgical method comprising: arranging a surgical device relative to a surgical site, wherein the surgical device includes a main shaft at least partially housing a first inserter carrying a first implant, a second inserter carrying a second implant, and a bone-preparing tool; forming a first bone hole using the bone-preparing tool; deploying the first implant into the first bone hole using the first inserter while the second implant remains within the main shaft; forming a second bone hole using the bone-preparing tool; and deploying the second implant into the second bone hole using the second inserter.
18 . The method as recited in claim 17 , further comprising passing a drill bit completely through the surgical device without interfering with the first inserter, second inserter, or the bone-preparing tool.
19 . The method as recited in claim 17 , further comprising: following deployment of the first implant, removing a first flexible strand attached to the first implant from the main shaft via a longitudinal slot extending an entire length of the main shaft; and following deployment of the second implant, removing a second flexible strand attached to the second implant from the main shaft via the longitudinal slot.
20 . The method as recited in claim 17 , wherein the main shaft includes a tip section configured to gradually converge the first inserter, second inserter, and bone-preparing tool toward a central longitudinal axis of the main shaft as the first inserter, second inserter, and bone-preparing tool are advanced distally within the tip section.

Description

RELATED APPLICATION(S) This application is a continuation of prior U.S. application Ser. No. 18/195,629, filed May 10, 2023, the entirety of which is herein incorporated by reference BACKGROUND When soft tissue such as a ligament or a tendon becomes detached from a bone, surgery is usually required to reattach or reconstruct the tissue. Often, a tissue graft is attached to the bone to facilitate regrowth and permanent attachment. Techniques and devices that have been developed generally involve using suture anchors to fix soft tissue to bone. SUMMARY This disclosure details a surgical device configured to deliver multiple implants or tools, including corresponding techniques, assemblies, systems, and methods, for using the surgical device. Among other benefits, the disclosed surgical device permits a user to deploy multiple implants or tools using a single surgical device, thereby reducing, or eliminating, the need to change surgical devices throughout a procedure. Further, the disclosed surgical device is configured to control the depth of insertion of the delivered implants or tools. A surgical device according to an exemplary aspect of the present disclosure includes, among other things, a main handle, a main shaft, an inserter partially within the main shaft, and an implant adjacent a distal end of the inserter. The surgical device is configured such that the implant is moveable from a retracted position within the main shaft to an intermediate position within the main shaft by distal movement of the inserter relative to the main handle. Further, the surgical device is configured such that the implant is moveable from the intermediate position to a deployed position distal of the main shaft by relative movement of the main shaft and the main handle. A surgical method according to another exemplary aspect of the present disclosure includes, among other things, preparing a region of a bone using a tool projecting distally from a main shaft of a surgical device, and inserting an implant into the prepared region of the bone using the surgical device. The implant is inserted by moving the implant from a retracted position within the main shaft to an intermediate position within the main shaft by distal movement of an inserter relative to a main handle of the surgical device, and by further moving the implant from the intermediate position to a deployed position distal of the main shaft by relative movement of the main shaft and the main handle.
