Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to a three-head titanium clamp capable of cutting blood vessels. Background Art

[0002] Currently, during liver tumor resection or partial liver resection surgery, it is necessary to block the blood flow to the liver to reduce bleeding during the operation and ensure the safety of the operation.

[0003] In clinical surgery, titanium clips are needed to clamp blood vessels to stop bleeding. The blood vessels at both ends need to be clamped and then cut. The existing double-headed titanium clamps with blood vessel cutting function cannot ensure that the titanium clips are firmly clamped on the blood vessels. The titanium clips may fall off and cause bile leakage. In addition, the double-headed titanium clamps are located on the same horizontal plane, making it difficult to clamp and cut some curved blood vessels. Summary of the invention

[0006] Preferably, the pliers head 1, the scissors and the pliers head 2 are all provided with hinge holes, one end of the pliers head 1 is fixedly connected to one end of the pliers rod 1 through a hinge shaft, and the scissors and the pliers head 2 are fixedly connected to one end of the pliers rod 2 through a hinge shaft. Preferably, the pliers head 1 has an installation groove 1 and an installation groove 2, the installation groove 1 and the installation groove 2 intersect in an X shape, the distance between the farthest points of the installation groove 1 and the installation groove 2 from the intersection is 1-2mm, the depth of the installation groove 1 is greater than the depth of the installation groove 2, and the upper and lower pliers of the pliers head 1 are the same.

[0007] Preferably, the width of the clamp rod one is greater than that of the clamp rod two, and the spacing between the clamp rod one connected to the clamp head one and the clamp head two connected to the clamp head two is 3-4 mm.

[0008] Preferably, there are two support rods, which are symmetrical with respect to the threaded rod. A connecting block is fixed to the bottom end of the support rod, one end of the connecting rod is fixed to the side of the connecting block, the other end of the connecting rod is connected to the threaded block, the threaded block is threadedly connected to the threaded rod, one end of the threaded rod is connected to a servo motor, and the servo motor is installed on a support.

[0009] Preferably, the other ends of the clamp rod 1 and the clamp rod 2 are connected to the clamp body, and a movable groove and a support are arranged in the clamp body.
