[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0018] Reference Figure 1-4 A bone tunnel positioning and wire-grabbing integrated sighting device for orthopedic surgery comprises a seat body 1 and a sliding handle 2 connected to one side thereof, the sliding handle 2 is provided with an arc-shaped sliding groove, an arc-shaped rod 3 is slidably connected in the arc-shaped sliding groove, a connecting handle 4 is provided at the end of the arc-shaped rod 3, the arc-shaped rod 3 and the sliding handle 2 are fixed by a fastener 9, an anchoring ring 7 is provided at the end of the connecting handle 4, a clamping mechanism is provided on one side of the anchoring ring 7, a guide hole is provided on the seat body 1, a hollow drill bit 5 is provided in the guide hole, and a guide rod 6 is inserted in the hollow drill bit 5.
[0019] The hollow drill bit 5 and the guide rod 6 are drilled into the anchoring ring 7 at the same time, and then the guide rod 6 is taken out, and at the same time, the suture is passed through the hollow drill bit 5 so that the suture passes into the anchoring ring 7. At this time, pressure is applied to the push button 10 to push the arc-shaped pressure head 8 toward the distal end in the plane of the anchoring ring 7. At this time, the anchoring ring 7 and the arc-shaped pressure head 8 are tightly closed to clamp the suture together, and then the aimer is taken out, and the suture is clamped out of the joint cavity, thereby improving the operating efficiency and eliminating the need to repeatedly enter the joint cavity for operation.
[0020] In this embodiment, the clamping mechanism includes an arc-shaped pressure head 8 located on one side of the anchoring ring 7, a through hole is provided inside the connecting handle 4, a flexible connector 11 is provided in the through hole, one end of the flexible connector 11 is connected to the arc-shaped pressure head 8, and the other end passes through the through hole and is connected to a push button 10.
[0021] In this embodiment, an elastic member 12 is disposed between the push button 10 and the arc-shaped rod 3 , and the elastic member 12 is sleeved on the flexible connecting member 11 .
[0022] In this embodiment, the width of the arc-shaped sliding groove gradually narrows from the groove bottom to the groove mouth, and the sliding handle 2 is threadedly connected to the fastener 9.
[0023] In this embodiment, the anchoring ring 7 is located at the center of the arc-shaped slide groove and is adjusted according to the required angle and position.
[0024] The developed meniscus posterior root precise locator can create a tibial tunnel in the meniscus posterior root attachment area with high positioning accuracy. At the same time, this precise locator is in the form of point-to-center, that is, a hollow drill is used to drill the bone tunnel. The hollow drill can pass through the center of the anchoring area. When the hollow drill passes through the center of the circle, the suture can be inserted into the hollow drill, and the suture can be grabbed out using the thread grabbing device of the anchoring circle. There is no need to remove the hollow drill and thread again, and then perform the thread grabbing operation. Due to the narrow joint cavity, it is difficult to repeatedly expose the meniscus posterior root area. This locator improves work efficiency, usability and safety. This sight can not only be used for the repair of the meniscus posterior root, but can also be widely used in various orthopedic surgeries that require the establishment of bone tunnels.
[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
