In a first embodiment, the present invention includes an instrumentation system for preparing a bone for soft tissue repair, the instrumentation system including a flexible drill pin capable of bending along a curved path; an aimer capable of engaging the flexible pin to bend the flexible pin; and a flexible reamer having a flexible portion along at least a portion of its length, the flexible portion comprising a plurality of laser cuts. In an alternate embodiment, the present invention may also include a method for preparing a bone tunnel in a femur adjacent a knee joint, the method including introducing a flexible drill pin into the knee joint; guiding the flexible drill pin towards a surface of the femur with an instrument introduced into the knee joint; drilling the flexible drill pin into the femur; removing the instrument from the knee joint; introducing a cannulated flexible reamer into the knee joint by placing the flexible pin within the cannulation of the flexible reamer; and reaming the bone tunnel in the femur along the path of the flexible pin.

A surgical device comprising a handling member comprising a sleeve with a central slot and a guiding pin, a guiding element that can be slid into the central slot and externally having a guiding groove that is slidably coupled to a guiding pin, locking means configured to lock the sliding of the guiding element inside the central slot, and switchable between an activation configuration, wherein the movement of the guiding element inside said central slot is prevented, and a deactivation configuration, wherein the movement of the guiding element is free. The guiding groove comprises a first and a second rectilinear groove portion, angularly spaced apart and mutually interconnected by means of a transversal connecting groove portion interposed between said first and said second rectilinear groove portions.

A drill guide assembly for accurate and stable drilling of a bone tunnel. The drill guide assembly includes a guide body having first and second ends, and a slot extending from the first end toward the second end. The drill guide assembly also includes a curved guide arm having a first arm connected at an angle to a second arm. The first arm terminates in a distal tip. The second arm has first and second sides, and is slidable within the slot of the guide body. The second arm also includes detents along its second side. A locking mechanism is attached at the first end of the guide body and in a first position, and the locking mechanism is engaged with one of the detents. The drill guide assembly also includes a clamp mechanism attached at the second end of the guide body and a guide sleeve removably extending therethrough.

A drill guide arm for providing guidance for placement of a bone tunnel, while protecting against trauma. The guide arm includes a first arm at a proximal end connected at an angle to a second arm, the second arm extending to a distal end. The angle can be within the range of 80°-110°. The second arm extends along a first axis. The guide arm also includes a distal tip extending at a second angle from the second arm at the distal end, and an indicator feature extending from the distal tip toward the first arm. The indicator feature extends along a second axis, the second axis being substantially parallel to the first axis. The guide arm can also include a shield feature of the distal tip. The shield feature has a width wider than the remainder of the distal tip.

A coracoid drill guide assembly includes a body having a cylindrical channel on each side of the body for receiving a drill guide sleeve. The sleeves of the assembly have a 1.4 mm inner diameter to guide a 1.3 mm (or smaller) K-wire through the sleeve. An aimer arm extends from the body at a non-intersecting angle with the drill sleeve. The assembly also has a self-locking ratchet mechanism to lock the sleeve in place once the assembly has been secured to bone.

Aspects of the present disclosure relate to systems, devices and methods for performing a surgical step or surgical procedure with visual guidance using an optical head mounted display. Aspects of the present disclosure relate to systems, devices and methods for displaying, placing, fitting, sizing, selecting, aligning, moving a virtual implant on a physical anatomic structure of a patient and, optionally, modifying or changing the displaying, placing, fitting, sizing, selecting, aligning, moving, for example based on kinematic information.

A surgical device for arthroscopy includes an insertion arm having a folded contact end, a handle connected to a connection end of the insertion arm, opposite to the folded contact end, and extending transversely to the insertion arm, and a retrieval element connected to the insertion arm and mobile along the insertion arm between a retracted position and an extracted position in which it intercepts a leading end of a suture thread at the folded contact end, and mobile between the extracted position and the retracted position in which it holds the leading end. The retrieval element is a basket made of flexible material defining a containment volume for receiving said leading end of the suture thread. The containment volume is configured to expand in the transition between the retracted position and the extracted position and to shrink in the transition between the extracted position and the retracted position.

Provided is a positioning system for posteromedial structure, posterolateral structure and medial patellofemoral ligament reconstruction, which relates to the technical field of ligament reconstruction. The system includes: a reconstruction channel coordinate system establishment module for establishing any one or more of a femoral coordinate system, a tibial coordinate system and a patellar coordinate system; a reconstruction channel bone feature point obtainment module for selecting femoral feature points, tibial feature points, fibular feature points or patellar feature points; and a reconstruction channel position determination module for determining a femoral point, a tibial point, a fibular point and a patellar point during reconstruction according to a preset reconstruction algorithm, and further determining a specific channel position of a posteromedial structure, posterolateral structure or medial patellofemoral ligament reconstruction channel by means of the femoral point, the tibial point, the fibular point and the patellar point. The present disclosure provides a standard method for selecting the femoral point, tibial point, fibular point or patellar point during tunnel reconstruction, which can make the specific path of the reconstruction tunnel more accurate.

A drill guide system provides a means of improved tunnel placement accuracy by allowing the drill guide to articulate to seat against the bone being drilled. The drill guide includes an articulating drill guide adapter constructed in four parts: a top cap, a thumbscrew, a lock tab, and a spring mechanism. The drill guide adapter is part of an aimer arm which mates with a handle on the proximal end and an aimer guide on the distal end. The drill guide adaptor allows the aimer guide to articulate relative to an irregular mating surface, allowing for increased area contact between the aimer guide template and bone. Examples of the drill guide adaptor also include a means for locking the aimer guide into place relative to the aimer arm.
