Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1-5: the utility model discloses a magnet-driven surgical clamp, which comprises a clamp (figure 3) and an external operation part (figure 4), wherein the clamp comprises a spring 5 and two clamping units 1 (figures 1 and 2), the clamping unit 1 comprises a clamping part 12, a connecting part 11 and a handheld part 13 which are arranged in sequence, and the middle of the connecting part 11 is provided with a through hole for connecting the clamping unit 1; the two clamping units are connected through two through holes, meanwhile, a magnet I2 is further arranged on the connecting portion 11, a spring fixing column 132 is arranged on the inner surface of the handheld portion 13, two ends of the spring 5 are connected with the spring fixing column 132, and the spring 5 is preferably a drum spring.

In order to further enhance the clamping force of the clamp on the tissue, the clamping part 12 is further provided with a clamping part through hole 121, the clamping part 12 and the handheld part 13 are respectively provided with a clamping part protrusion 122 and a handheld part protrusion 131, as shown in fig. 6, the two clamping part protrusions 122 are distributed in a staggered manner, which is beneficial to enhancing the clamping force, and the protrusions (the clamping part protrusion 122 and the handheld part protrusion 131) at the two parts are both perpendicular to the axis (dotted line in fig. 1) of the position where the protrusions are located, so that the protrusion direction can be perpendicular to the pulling direction of the clamp as much as possible when the body tissue is pulled by the clamp, and the clamp is prevented from being separated from.

With reference to fig. 4 and 5: the external operation part comprises a second magnet 3 and an external handheld part 4, one end of the external handheld part 4 is connected with the second magnet 3, and the other end of the external handheld part is provided with a handheld ring 41 convenient to operate.

The utility model discloses a magnet one 2 and the equal neodymium iron boron magnet of preferred magnetism preferred of two 3 of magnet.

During the use, put the clamp to internal through the surperficial incision of health earlier, then the internal tissue that needs pull open is cliied in the operation clamp, at this moment, the clamp tightly cliies internal tissue under spring 5's effect, because clamping part 12 is equipped with clamping part through-hole 121 and clamping part arch 122, consequently spring 5 can firmly clip internal tissue through less elasticity, accomplish internal centre gripping back, alright attract with internal magnet 2 through the magnet two 3 of external operation, drive the removal of internal clamp through removing magnet two 3, thereby pull open internal tissue.

The utility model discloses an operation pincers can slide in vivo through the magnetism drive operation clamp between outside magnet (magnet two) and inside magnet (magnet one) after the centre gripping of completion to the tissue to reach the purpose that does not need the contact clamp to operate the clamp, owing to when removing through inside magnet of outside magnet pulling, need not to operate through the incision on health surface, consequently can reduce the notched area of health.
