Description

Technical Field

[0001] The utility model relates to the technical field of cartilage repair auxiliary devices, in particular to a cartilage repair auxiliary device. Background Art

[0002] Cartilage repair refers to repairing damaged cartilage tissue through surgery or other methods to promote healing and regeneration of damaged areas. Common cartilage repair methods include cartilage transplantation, cartilage repair surgery, and stem cell therapy. These methods can improve the pain and dysfunction caused by cartilage damage and help restore the normal function of damaged joints. When performing cartilage repair on the legs, most of the time, the patient's legs are directly lifted and supported before surgery. Not only can the patient's leg bend not be adjusted according to surgical needs, but also during the long operation, the contact surface between the patient's legs and the support is prone to sweating, which affects the patient's comfort. Therefore, we have launched a cartilage repair auxiliary device. Utility Model Content

[0003] The main purpose of the utility model is to provide a cartilage repair auxiliary device, which can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A cartilage repair auxiliary device includes a connecting seat, a sliding groove is opened at the front of the upper end of the connecting seat, and the rear groove wall of the sliding groove is movably connected to a threaded rod through a bearing, the front end of the threaded rod is fixedly connected to a rotating wheel, the threaded rod extends to the front end of the connecting seat, the rotating wheel is located at the front of the connecting seat, the outer surface of the threaded rod is threadedly connected to a sliding seat, the sliding seat is slidably connected to the sliding groove, a No. 2 lifting plate is arranged in the middle of the upper end of the connecting seat, and a No. 1 lifting plate is arranged at the rear of the upper end of the connecting seat, the upper ends of the No. 2 lifting plate and the No. 1 lifting plate are both curved structures, and the inner walls of the No. 2 lifting plate and the No. 1 lifting plate are opened with a plurality of air holes that pass through up and down.

[0006] Preferably, a hinge No. 1 is installed at the rear portion of the upper end of the connecting seat, and the lifting plate No. 1 is movably connected to the connecting seat via the hinge No. 1.

[0007] Preferably, a No. 3 hinge is fixedly connected to the upper end of the sliding seat.

[0008] Preferably, the sliding seat is movably connected to the No. 2 lifting plate via a No. 3 hinge.

[0009] Preferably, the ends of the No. 1 lifting plate and the No. 2 lifting plate that are close to each other are commonly connected with a No. 2 hinge.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. By setting the No. 2 lifting board and the No. 1 lifting board, the patient's thigh is placed on the No. 1 lifting board, and the patient's calf is placed on the No. 2 lifting board. Since the upper ends of the No. 2 lifting board and the No. 1 lifting board are both arc structures, the patient's legs can be lifted and prevented from sliding and displacement. The threaded rod is driven to rotate by rotating the rotating wheel, so that the sliding seat on the threaded rod can adjust its position forward and backward in the sliding groove. During the movement of the sliding seat, the No. 2 lifting board and the No. 1 lifting board can adjust their angles under the influence of the sliding seat, so as to adjust the bending degree of the patient's legs according to the needs of the operation, thereby improving the convenience of the operation;

[0012] 2. By opening a number of ventilation holes on the No. 2 lifting board and the No. 1 lifting board, air can circulate between the contact surfaces between the patient's legs and the No. 2 lifting board and the No. 1 lifting board, thereby preventing the patient's legs from sweating and affecting comfort, and reducing the cleaning burden on medical staff.
