Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a postoperative shoulder joint braking device. Background Art

[0002] For breast cancer surgery, shoulder joint surgery, etc., after the surgery, the patient needs to brake the shoulder joint during the recovery process, that is, fix the shoulder joint. There are various types of brake brackets on the market, including sling type, abduction type, etc. For the braking of the shoulder joint, the general solution is to fix it by rotating the connected lateral waist support and upper arm support, and the opposite surfaces of the lateral waist support and upper arm support are fixed by oblique support to form a stable triangular structure. However, this device has some shortcomings: first, the length of the oblique support is generally not adjustable. When adjusting the angle of the lateral waist support and the upper arm support, it is necessary to adjust the connection position of the two ends of the oblique support at the lateral waist support and the upper arm support. Generally, the bolt locking adjustment is performed through equidistant holes. The adjustment method is relatively cumbersome and cannot be continuously fine-tuned; second, the oblique support is generally connected to the central axis position of the lateral waist support and the upper arm support, lacking lateral support, which also makes the support unstable.

[0004] The utility model adopts the following technical solutions:

[0005] The postoperative shoulder joint braking device comprises a lateral lumbar support and an upper arm support connected by a rotating shaft. The lateral lumbar support and the upper arm support have the same structure and both comprise a profile straight arm. A slide groove is formed on the inner side surface of the profile straight arm. A matching slide groove is arranged in the slide groove. A lower support rod is connected to the rotating shaft on the slide. The connection position between the lateral lumbar support and the upper arm support is a rotating shaft. Both ends of the rotating shaft are connected to middle support rods. The ends of the two middle support rods and the ends of the two lower support rods are hinged together. A locking assembly for locking the slide plate is also arranged on the profile straight arm.

[0006] Furthermore, the side of the skateboard is a rack, and the locking assembly includes a shell fixed to the side wall of the straight arm of the profile, the shell has a convex groove, the convex groove has a movable convex block, the inner side of the convex block is a row of convex teeth matching the rack, a pair of compression springs are installed in the convex groove and on the outer side of the convex block, and a push screw is screwed on the outside of the shell toward the convex block.

[0007] Furthermore, the cross section of the slide plate is T-shaped to match the slide groove.

[0008] Furthermore, the outer side surfaces of the straight arms of the profile are fixed with contour supports, and the contour supports are provided with holes.

[0009] Furthermore, corner blocks are fixed on the tops of the straight arms of the profiles, and the two corner blocks are connected by rotating shafts.

[0010] The beneficial effects of the utility model are as follows: the structure has a total of four supporting rods, among which the lateral waist support and the upper arm support form a triangular support with the lower rod and the middle rod on the same side, so the structure has a total of two triangular supports; at the same time, there are two middle rods, which respectively support the two ends of the rotating shaft, thereby realizing lateral support to a certain extent, and can significantly improve the support stability; in addition, in the present structure, when adjusting the angle, the slide slides in the slide groove and is then locked by the locking assembly, so that continuous position adjustment can be achieved, and the adjustment is also more convenient.

[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0015] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0016] like Figure 1-2 As shown, the postoperative shoulder joint braking device provided in this embodiment includes a lateral lumbar support and an upper arm support connected by a rotating shaft. The lateral lumbar support and the upper arm support have the same structure and both include a profile straight arm 1. A slide groove 2 is formed on the inner side of the profile straight arm 1. A matching slide plate 3 is arranged in the slide groove 2. A lower support rod 4 is connected to the rotating shaft on the slide plate 3. The connecting position of the lateral lumbar support and the upper arm support is a rotating shaft. Both ends of the rotating shaft are connected to a middle support rod 5. The ends of the two middle support rods 5 and the ends of the two lower support rods 4 are hinged together. There is also a locking assembly 6 on the profile straight arm 1 for locking the slide plate.

[0017] In this structure, the side waist support and the upper arm support are rotatably connected. Specifically, the top of the straight arm 1 of the profile is fixed with an angle block 8, and the two angle blocks 8 are connected by a rotation axis. In the figure, the side waist support and the connected lower support rod and two middle support rods form a triangular support, and the upper arm support is also a triangular support on the connected lower support rod and two middle support rods. Therefore, the support structure of this device is two stable triangles. At the same time, the two middle support rods support the two ends of the rotation axis respectively, so lateral support can also be formed to a certain extent, and the entire support structure is more stable.

[0018] When in use, the outer side of the straight arm 1 of the profile is fixed with a profiling support 7, which has a hole. The binding belt is inserted through the hole to fix the profiling support to the side of the body and under the arm, thereby forming a stable support.

[0019] On the other hand, when adjusting the support angle of the side waist support and the upper arm support, it can be adjusted directly. At this time, the slide slides in the slide groove, and then the locking assembly is locked, which can achieve continuous angle adjustment and the adjustment method is also very simple. Furthermore, the cross section of the slide is T-shaped to match the slide groove, and the sliding is smoother and more stable.

[0020] As a specific structure of the locking assembly 6, Figure 3 As shown, the side of the slide plate 3 is a rack 31, and the locking assembly 6 includes a housing 61 fixed to the side wall of the straight arm of the profile, and the housing 61 has a convex groove, and the convex groove has a convex block 62 that can move forward and backward, and the inner side of the convex block 62 is a row of convex teeth that match the rack 31. A pair of compression springs 63 are installed in the convex groove and on the outer side of the convex block 62, and a push screw 64 is screwed on the outside of the housing 61 toward the convex block 62. In addition, there are positioning cylinders at both ends of the compression spring to limit the spring from being out of position.

[0021] Figure 3 The picture shows the locked state, where the push screw is tightly against the convex block, so that the convex block and the convex teeth are meshed with the side rack of the skateboard. At this time, the convex block is locked and the skateboard cannot move in the slide slot. When the push screw is loosened, the push screw retreats and the skateboard can be moved directly. During the movement, under the action of the compression spring, the convex block moves back and forth without affecting the movement of the skateboard. After moving to the appropriate position, tighten the push screw to limit the convex block to complete the locking. Therefore, it can be seen that the adjustment method of this structure is very simple. You only need to loosen and tighten the push screw, and it can be adjusted continuously. The existing method uses a row of equidistant holes, which requires the nut to be completely unscrewed, then aligned and screwed in, and it cannot be adjusted continuously, and the effect is not as good as this structure.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
