[0050] The embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0051] The medical connecting lock clamp 100 and the tissue distraction device according to the embodiments of the present application are described below with reference to Figures 1-12 The medical connecting lock clamp 100 and the tissue distraction device according to the embodiments of the present application are described below with reference to

[0052] The medical connecting lock clamp 100 according to the embodiments of the present application has a clamping state and a relaxed state, and the connecting lock clamp 100 comprises a base column 1, a clamping member 2 and an adjusting member 3.

[0053] The length extension direction of the base column 1 (for example,​Figure 11 One end of the clamping member 100 (shown in the vertical direction) has a stop 11; the base post 1 passes through a part of the clamping member 2 and abuts against the stop 11 with a part of the clamping member 2; the other part of the clamping member 2 forms a compressible clamping part 221, which forms a clamping rod cavity 222 for inserting and positioning the rod; the adjusting member 3 is hinged to the other end of the base post 1 in the length extension direction, and a part of the clamping member 2 is clamped between the adjusting member 3 and the stop 11, so that the clamping member 2 is deformed along the length extension direction of the base post 1 by the rotation of the adjusting member 3, so that the connecting lock 100 can change between a clamped state and a relaxed state.

[0054] The medical connecting clamp 100 of this utility model has a compressible clamping portion 221 formed on the clamping member 2, and a clamping rod cavity 222 formed on the clamping portion 221 for inserting and positioning a rod (medical tube or rod, such as column 200 and connecting frame 300). The adjusting member 3 is hinged to the other end of the base column 1 along its length extension direction. A portion of the clamping member 2 is clamped between the adjusting member 3 and the stop portion 11. By rotating the adjusting member 3, the clamping member 2 is compressed and deformed along the length extension direction of the base column 1, thereby allowing the connecting clamp 100 to switch between a clamped state and a relaxed state. When it is necessary to adjust the relative position and angle of the rod, the connecting clamp 100 can be adjusted to the relaxed state by rotating the adjusting member 3, and then the rod can be moved to the relative position and / or angle to achieve a better surgical field of view. This helps to improve the convenience of surgical operations. In situations where medical resources are scarce, it helps to reduce the number of assistants required, thereby improving overall medical efficiency.

[0055] Therefore, the medical connecting lock clip 100 of this utility model embodiment has the advantage of high ease of operation.

[0056] It should be noted that the clamping part 221, which is compressible and deformable, is formed on another part of the clamping member 2. This means that when one part of the clamping member 2 is compressed, the clamping rod cavity 222 deforms. In the clamping state, the clamping part 221 clamps and fixes the rod body. In the relaxed state, the rod body can move relative to the clamping part 221.

[0057] like Figures 10 to 12 As shown, the clamping member 2 includes an integrally bent first plate 21, a bent portion 22, and a second plate 23. The first plate 21 and the second plate 23 are arranged opposite to each other along the length extension direction of the base column 1. An arc-shaped clamping rod cavity 222 is formed on the bent portion 22. The adjusting member 3 can squeeze one of the first plate 21 and the second plate 23 to reduce the width of the clamping rod cavity 222.

Therefore, by the position setting of the hinge point on the adjusting piece 3, the change of the state of the clamping piece 2 can be realized. Therefore, the medical connecting lock clamp 100 has the advantage of relatively simple structure.

[0071] As shown, Figures 9 to 12 The adjusting piece 3 is in the shape of a handle. By setting the adjusting piece 3 into the shape of a handle, the operation convenience is further improved.
