Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a titanium plate with a loop. Background Art

[0002] The titanium plate with loops is a commonly used medical device in orthopedic reconstruction and repair surgery. It can be used for acromioclavicular joint dislocation, tibiofibular joint, and knee cruciate ligament reconstruction to restore patients' joint function and return to sports.

[0003] In the prior art, the main body of the titanium plate with a loop specifically includes a titanium plate, sutures, traction wires and flip-loop wires. The titanium plate is provided with a number of perforations spaced apart along its length for the traction wires, sutures and flip-loop wires to pass through respectively. The titanium plate is pulled into a pre-drilled bone channel through the traction wire, passes through the cortical bone, and the flip-loop wire is pulled to flip the titanium plate. The sutures are then tightened and tied, and the traction rope and flip-loop wire are removed to complete the repair surgery.

[0004] Since the surface of some titanium plates is usually flat, when used on curved surfaces or human tissues with relatively uneven surfaces, there may be a gap between the titanium plate and the bone surface, resulting in poor fit. After surgery, when the ligaments are stretched, the sutures may be pulled, causing relative displacement between the titanium plate and the bone, affecting the subsequent stability of the titanium plate, so further improvement is needed. Utility Model Content

[0005] In order to improve the fit between the titanium plate and human tissue, the present application provides a titanium plate with a loop.

[0006] The present application provides a titanium plate with a loop, which adopts the following technical solution:

[0007] A titanium plate with loops comprises a titanium plate body and sutures, traction lines and loop lines which are all slidably arranged in the titanium plate body. Both ends of one surface of the titanium plate body are arched to form two first arcuate surfaces, and the first arcuate surfaces are used to abut against human tissue.

[0008] By adopting the above technical solution, both ends of one surface of the titanium plate body are arched to form two first arc-shaped surfaces for contacting against human tissue, so as to improve the fit between the titanium plate body and the human tissue, reduce the possibility of relative slippage between the titanium plate body and the human tissue, and reduce the protrusion of hard objects, which is convenient for reducing the pressure on human tissue in operations such as acromioclavicular joint dislocation, distal tibiofibular syndesmosis, and knee cruciate ligament reconstruction, thereby increasing the comfort of patients' postoperative recovery and improving their postoperative comfort.

[0009] Preferably, an abutment surface is provided in the middle of the titanium plate body, and the abutment surface is parallel to the highest points of the two first arc-shaped surfaces.

[0010] By adopting the above technical solution, the middle of the titanium plate body is parallel to the highest points of the two first curved surfaces, so as to further improve the fit between the titanium plate body and the human tissue, increase the contact area, reduce the pressure on the human tissue, and increase the corresponding comfort. The overall thickness of the titanium plate body can be limited to reduce the possibility of jamming during subsequent bone tunneling and reduce the difficulty caused by the first curved surface during surgery.

[0011] Preferably, the abutting surface is parallel to the surface of the titanium plate body away from the first arc-shaped surface.

[0012] By adopting the above technical solution, the abutting surface is parallel to the surface of the titanium plate body away from the first arc surface, so as to be smoothly penetrated in some deeper bone tunnels, thereby further reducing the possibility of jamming when penetrating the bone tunnel.

[0013] Preferably, two first through-holes are penetrated through the middle of the titanium plate body, the two ends of the suture are respectively penetrated through the two first through-holes and wrapped around the titanium plate body, and the two ends of the titanium plate body are located on the first arc-shaped surface and penetrated through second through-holes, the traction line and the loop line are respectively penetrated through the second through-holes and are respectively wrapped around the two end surfaces of the titanium plate body.

[0014] By adopting the above technical solution, the two ends of the suture are respectively passed through the first perforation and wrapped around the titanium plate body to achieve appropriate adjustment of the length of the loop, so as to improve the fit between the titanium plate body with loop and human tissue; and the traction line and the loop line are respectively passed through the second perforation and respectively wrapped around the two end surfaces of the titanium plate body to increase the force-bearing area, so as to pull the traction line and the loop line.

[0015] Preferably, the second perforation is arranged in an elliptical shape along the width direction of the titanium plate body.

[0016] By adopting the above technical solution, the second perforation is arranged in an elliptical shape along the width direction of the titanium plate body, so as to reduce the damage to the traction line and the loop line when pulling. At the same time, the force bearing area of ​​the suture traction line and the loop line and the second perforation can be increased, which is convenient for pulling the traction line and the loop line.

[0017] Preferably, the edge of the first perforation is rounded.

[0018] By adopting the above technical solution, the edge of the first perforation is set to be chamfered, and the size of the cross-section of the first perforation along the thickness direction of the titanium plate body can be appropriately set to gradually increase toward the two surfaces of the titanium plate body, thereby reducing the gap between the suture and the titanium plate body at the inner wall of the first perforation, so as to improve the firmness of the subsequent binding sutures, thereby reducing the possibility of relative movement of the titanium plate body during ligament stretching.

[0019] Preferably, a second arcuate surface is provided on a surface of the titanium plate body away from the abutting surface, and the second arcuate surface is arranged in a V-shape along the thickness direction of the titanium plate body.

[0020] By adopting the above technical solution, a second curved surface is provided, and the second curved surface is arranged in a V-shape along the thickness direction of the titanium plate body, so that the nodule formed after the suture is tied is built into the second curved surface, and the binding is relatively stable, thereby reducing the possibility of relative movement of the titanium plate body during ligament stretching.

[0021] Preferably, both end surfaces of the titanium plate body are arranged as curved surfaces, and the edges of the titanium plate body are arranged as chamfered corners.

[0022] By adopting the above technical solution, the corners of the titanium plate body are not likely to touch human tissues, thereby preventing discomfort or scratching human tissues.

[0023] In summary, the utility model has the following beneficial effects:

[0024] 1. The first arc surface is formed by arching the two ends of the titanium plate body toward one of its surfaces to abut against human tissue, so as to improve the fit between the titanium plate body and the human tissue, reduce the possibility of relative slippage between the titanium plate body and the human tissue, and reduce the protrusion of hard objects, so as to reduce the pressure on human tissue in operations such as acromioclavicular joint dislocation, tibiofibular joint, and knee cruciate ligament reconstruction, and increase the comfort of patients' postoperative recovery to improve the comfort of patients after surgery.

[0025] 2. The second perforation is arranged in an elliptical shape along the width direction of the titanium plate body to reduce the damage to the traction line and the loop line when pulling. At the same time, the force bearing area of ​​the suture traction line and the loop line and the second perforation can be increased, which is convenient for pulling the traction line and the loop line.
