Description

Technical Field

[0002] Among medical tools, there are many types of soft tissue clamps used in hospital surgeries. However, with the development of medical technology, our requirements for soft tissue clamps are getting higher and higher. We hope to improve the efficiency of soft tissue clamps through innovation, so as to reduce the trouble of using them and maximize their value. Therefore, corresponding soft tissue positioning clamps are derived.

[0003] The positioning clamps currently available on the market are not convenient for repeatedly opening and closing the first clamp and the second clamp, which makes it difficult to achieve the expected clamping effect and needs to be improved.

[0004] To solve the above problems, after searching, a Chinese patent with the authorization announcement number CN219289719U discloses a rotatable and repeatedly openable and closed soft tissue clamp positioning clamp; the invention includes driving the connecting rod 5 through the disc 2 to slide rightward inside the limiting sleeve 4, so that the connecting rod 5 drives the first clamp 7 and the second clamp 8 to rotate around the bearing 9, and the first clamp 7 and the second clamp 8 are moved to the inside of the second circular tube 6 to achieve the purpose of closing, and then pushing the handle 11 to the left to drive the connecting rod 5 through the disc 2 to slide leftward inside the limiting sleeve 4, so that the first clamp 7 and the second clamp 8 are pushed to the outside of the second circular tube 6, because one end of the first clamp 7 and the second clamp 8 are connected to the outer wall of the bearing 9 through the torsion spring, so that the angle of the first clamp 7 and the second clamp 8 is reset to an open state to achieve the purpose of opening and closing;

[0005] Although the above-mentioned device can realize the positioning and clamping of soft tissue, the operation method is not fast enough and cannot be operated with one hand, which increases the difficulty of using the device. There is room for improvement in the structure, which led to the present case. Utility Model Content
