[0053] In an optional embodiment, the Achilles tendon suturing device further includes a holding member 81, the first fixing member 41 is externally provided with a shell structure 44, one end of the holding member 81 is fixedly connected with the shell structure 44, and the other end of the holding member 81 is fixedly connected with the middle part of the shell structure 44, and the outer side wall of the holding member 81 is provided with a grid structure.

[0054] In the embodiments of the present application, the holding member 81 is provided to achieve the holding of the Achilles tendon suturing device, in a specific embodiment, the outer side wall of the holding member 81 is provided with a grid structure, thereby avoiding the falling off when the holding member 81 is held by hand, so as to improve the stability of the Achilles tendon suturing device, in actual application, the holding member 81 can be a handle.

[0055] In an optional embodiment, as shown in Figs. 1-3As shown, the Achilles tendon suture device further comprises a first limiting baffle 51 and a second limiting baffle 52, wherein the first limiting baffle 51 and the second limiting baffle 52 are parallel to each other, and the first limiting baffle 51 and the second limiting baffle 52 are arranged in a spaced manner, the extension direction of the first limiting baffle 51 and the extension direction of the second limiting baffle 52 are the same as the extension direction of the first clamping piece 21, when the first clamping piece 21 and the second clamping piece 22 are in the clamping state, at least part of the structure of the first limiting baffle 51 is located on the upper side of the first clamping piece 21 and the second clamping piece 22, and at least part of the structure of the second limiting baffle 52 is located on the lower side of the first clamping piece 21 and the second clamping piece 22.

[0056] Specifically, when the Achilles tendon is clamped by the first clamping piece 21 and the second clamping piece 22, the first limiting baffle 51 and the second limiting baffle 52 can support and fix the top and bottom of the Achilles tendon respectively, thereby avoiding the Achilles tendon from slipping out of the first clamping piece 21 and the second clamping piece 22 due to gravity or the Achilles tendon from sliding upward between the first clamping piece 21 and the second clamping piece 22 due to extrusion when the Achilles tendon is clamped by the first clamping piece 21 and the second clamping piece 22, thereby further improving the stability during the suture process.

[0057] The specific working principle of the Achilles tendon suture device will be described below.

[0058] Specifically, first, a knife is used to cut a vertical incision to expose the Achilles tendon stump and separate the tendon membrane, and then the first adjusting piece 31 is rotated to adjust the distance between the first support piece 11 and the second support piece 12, so that the distance between the first support piece 11 and the second support piece 12 is approximately matched with the skin outside the Achilles tendon on both sides, at the same time, the second adjusting piece 32 is rotated to adjust the distance between the first clamping piece 21 and the second clamping piece 22, so that the distance between the first clamping piece 21 and the second clamping piece 22 is approximately matched with the width of the Achilles tendon, and then the first clamping piece 21, the second clamping piece 22, the first limiting baffle 51 and the second limiting baffle 52 are inserted from the exposed Achilles tendon stump by holding the holding piece 81, at this time, the first clamping piece 21 and the second clamping piece 22 are located on the left and right sides of the Achilles tendon, and the first limiting baffle 51 and the second limiting baffle 52 are located on the upper and lower sides of the Achilles tendon, then the first adjusting piece 31 and the second adjusting piece 32 are continuously rotated to tighten and fix the skin outside the Achilles tendon on both sides by the first support piece 11 and the second support piece 12, and to tighten and fix the Achilles tendon by the first clamping piece 21 and the second clamping piece 22.

[0059] Secondly, the suture 71 is inserted through the first threading hole 61 on the first support 11, and the suture 71 is used to thread the suture from the first threading hole 61 on the first support 11, sequentially through the skin outside the Achilles tendon, the first threading matching hole 63 on the first clamping piece 21, the Achilles tendon, the second threading matching hole 63 on the second clamping piece 22 and the skin outside the Achilles tendon, and out of the second threading hole 62 on the second support 12, and then the suture 71 is separated from the suture, at this time, the middle part of the suture stays in the structure of the Achilles tendon and the Achilles tendon, and the two ends of the suture are exposed outside, and finally, the same method is used to thread multiple sutures into the Achilles tendon, at this time, the first adjusting piece 31 and the second adjusting piece 32 can be reversely rotated, and the holding piece 81 is pulled out, so that the first clamping piece 21, the second clamping piece 22, the first limiting baffle 51 and the second limiting baffle 52 are pulled out, at this time, the suture can be pulled out from the left and right sides of the Achilles tendon, and the suture is fixed and knotted, so that the suture of the ruptured Achilles tendon can be realized.
