A suture threader configured to thread sutures through suture holes in a bone plate, including: a base; a plurality of hooks attached to the base, wherein the plurality of hooks are arranged at positions on the base corresponding the suture holes on the bone plate.

Suture threader for bone plate

A bone screw insertion device, comprises an outer sleeve extending from a proximal end to a distal end and including a channel extending therethrough and a driving member extending longitudinally through the channel of the outer sleeve from a proximal end to a distal end configured to engage a driving recess of a bone screw, the outer sleeve movable relative to the driving member between a first position in which the distal end of the outer sleeve extends over and covers a proximal portion of a bone screw engaged with the driving member, to a second position in which the distal end of the outer sleeve is longitudinally aligned with a proximal end of a bone screw engaged with the driving member.

Self-retaining screw and screwdriver

A device includes an outer sleeve of flexible material forming an outer conduit extending longitudinally therethrough for the insertion of a bone treatment device ('BTD') to target sites within a living body. A distal opening of the outer conduit is open so that, when the outer sleeve is in a desired position within the body, BTD is inserted through the outer conduit exits the outer sleeve adjacent to a target portion of a bone. The device also includes an inner sleeve received within the outer sleeve and defining an inner conduit within the outer conduit to form a protective covering. The inner sleeve is split longitudinally. Portions of the inner sleeve on opposite sides of the split are coupled to one another so that a diameter of the inner conduit is adjustable in response to forces exerted thereon by one of BTD and tissues surrounding the outer sleeve.

Device and system for facilitating insertion of a bone treatment device

In one example, a system has an insertion handle that can be coupled to an intramedullary nail and includes a first coupler that defines one of a recess and a projection, and one of a latch and an abutment surface. The system has an aiming guide that includes a guide body that defines at least one alignment aperture therethrough. The aiming guide includes a second coupler that can couple the guide body to the first coupler such that the at least one alignment aperture is positioned to guide an instrument towards at least one bone-anchor fixation hole of the intramedullary nail. The second coupler defines another of the recess and the projection, and another of the latch and the abutment surface. The first and second couplers can couple to one another by receiving the projection in the recess and by engaging the latch with the abutment surface.

System and method of coupling an alignment guide to an intramedullary nail insertion handle

In one embodiment, a strike instrument that couples to an insertion handle of an intramedullary nail has a shaft that extends along a shaft axis, and an abutment that extends outward relative to the shaft. The abutment is rotationally fixed to the shaft such that the shaft can rotate the abutment between a first orientation, where the abutment can be removed or inserted into the insertion handle, and a second orientation, where the abutment forms an interference with the insertion handle that prevents the abutment from being removed from the handle. The strike instrument includes a strike surface that can transfer an impaction force to the insertion handle, and a lock that engages the insertion handle so as to prevent the abutment from rotating from the second orientation to the first orientation after the abutment is rotated within the insertion handle from the first orientation to the second orientation.

Strike instrument for intramedullary nail

A depth gauge device including a body extending a central longitudinal axis and including a channel and a light-passing hole, the light passing hole open to the channel, a light source mounted in the body for generating a light beam, the light beam passing through the light-passing hole toward a surface of a drill-bit extending through the channel, the light beam forming an incident light beam when reflected away from the drill-bit surface, an image sensor mounted in the body for sensing the incident light beam and generating a plurality of successive images of the drill-bit surface to detect variations in the position of the drill-bit moving through the channel and an clamp coupled to the body, the clamp including a plurality of adjustable arms configured to clamp the device to a protection sleeve.

Universal direct measurement depth gauge

A system, comprises an implant including an outer sleeve and a head element, the outer sleeve extending longitudinally and including a channel extending therethrough, the head element including a shaft portion and a bone-engaging portion, the shaft portion received within the channel of the outer sleeve and longitudinally movable relative thereto and a clip device removably assembled with the implant to hold the outer sleeve and the head element in a desired position relative to one another, the clip device including a body extending longitudinally along with a separation portion connected to a proximal end of the body via a releasable connection to engage the proximal end of the outer sleeve and a spacer portion connected to the proximal end of the body to releasably engage a portion of the shaft portion between a proximal end of the bone-engaging portion and the distal end of the outer sleeve.

Break off spacer clip for trochanteric femoral nail telescoping head element

An artificial knee joint () is described and comprises a femoral component () and a tibial component (), for attachment to the femur () and tibia () of a patient () respectively. The femoral component () comprises a lateral condyle () and a medial condyle () which extend from the posterior () to the anterior () of the femoral component (). A femoral gap () is provided between the lateral () and medial () condyles extending from the posterior () toward the anterior () of the femoral component (). The lateral () and medial () condyles are joined at the anterior () of the femoral component () to form a patella tracking path or bearing surface () which is located at and forms the anterior end of the gap (). A femoral cam () is provided bridging the posterior ends of both the lateral () and medial () condyles, and forms a posterior end of the gap (), wherein the femoral cam () is structured to have the shape of a section of a ring (). The tibial component () is provided with two approximately symmetric articulation bearing surfaces () either side of a central post (), wherein the articulation bearing surfaces () are for receiving the lateral () and medial () condyles of the femoral component (), and the post () is shaped such that it will fit within the femoral gap ().
