[0018] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0019] See also Figure 1~Figure 4 , the utility model embodiment includes:
[0020] like Figure 1 and Figure 2The medical limited compression pliers shown include: a first pliers handle 1, a second pliers handle 2, a compression baffle 4, a first support leg 10 and a second support leg 8. The front ends of the first pliers handle 1 and the second pliers handle 2 are cross-connected to the back of the compression baffle 4 through a gill axis screw 3. The first pliers handle 1 and the second pliers handle 2 are relatively long, and the gripping operation is relatively labor-saving. In this embodiment, a support spring 12 is provided between the first pliers handle 1 and the second pliers handle 2, which is conducive to the opening of the first pliers handle 1 and the second pliers handle 2 after closing, and the operation is flexible.
[0021] A first clamp head 7 is arranged at the front end of the first clamp handle 1 and is located behind the compression baffle 4. A second clamp head 11 is arranged at the front end of the second clamp handle 2 and is located behind the compression baffle 4. Figure 3 As shown, the compression action is performed by closing the first clamp handle 1 and the second clamp head 11.
[0022] In order to improve safety, a limiting groove 6 corresponding to the path of the first clamp 7 and the second clamp 11 is provided on the compression baffle 4, and a limiting pin 5 extending to the corresponding limiting groove 6 is provided on the first clamp 7 and the second clamp 11. The limiting groove 6 and the limiting pin 5 are cooperated with each other to limit the first clamp 7 and the second clamp 11 on the compression closing path, thereby improving the safety of compression operation within a certain range.
[0023] The first support leg 10 and the second support leg 8 are symmetrically arranged on both sides of the top of the compression baffle 4. Figure 1 As shown, the first support leg 10 and the second support leg 8 are located in front of the angle between the first clamp head 7 and the second clamp head 11, and a limit block extending between the first clamp head 7 and the second clamp head 11 can be fixed by the first support leg 10 and the second support leg 8. The compression path limit of the first clamp head 7 and the second clamp head 11 is determined by the diameter of different limit blocks, thereby further improving the compression displacement accuracy.
[0024] In this embodiment, a connecting block 9 is provided on the top of the compression baffle 4 between the first leg 10 and the second leg 8, and a rivet 13 is provided between the first leg 10 and the second leg 8 to penetrate the connecting block 9, so that the assembly is convenient and the structure is stable. The compression baffle 4 and the connecting block 9 adopt an integrated structure and are made of stainless steel material with high strength.
[0025] like Figure 4 As shown, the first and second convex ribs 15 and 14 extending vertically are arranged at intervals on the inner sides of the first support leg 10 and the second support leg 8. A clamping groove 16 is formed between the first and second convex ribs 15 and 14, which is conducive to fixing the head of the limit block 17 through the clamping grooves 16 on both sides. The head of the limit block 17 adopts a stepped shaft structure and is clamped into the clamping grooves 16 on both sides. In this embodiment, the protruding thickness of the first convex rib 15 is less than the protruding thickness of the second convex rib 14. The small protruding thickness of the first convex rib 15 is conducive to the insertion installation of the head of the limit block from the front.
[0026] In summary, the medical limiting compression pliers pointed out in the utility model can limit and adjust the compression, thereby improving the compression displacement accuracy and operation safety.
[0027] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention.
