[0029] As described in the background art, tendon suturing requires at least two people to operate simultaneously.

[0035] Embodiment 1:

[0036] Please refer to Figure 2-Figure 6 A tendon rupture auxiliary suture device, comprising a tendon clamping mechanism 1, a tendon docking mechanism 2 and a clamping adjustment mechanism 3, wherein the surface of the tendon clamping mechanism 1 is connected with the tendon docking mechanism 2 for connecting the tendon clamping mechanism 1, and the middle part of the tendon clamping mechanism 1 is connected with the clamping adjustment mechanism 3 for auxiliary clamping of the tendon;

[0037] The tendon clamping mechanism 1 includes a first fixing ring 4, a second fixing ring 5, a third fixing ring 6, a fourth fixing ring 7, an auxiliary suture opening 12 and a combined fixing component. The bottom surface of the first fixing ring 4 is hingedly connected to the second fixing ring 5, the right side of the first fixing ring 4 is connected to the third fixing ring 6, the bottom end of the third fixing ring 6 is hingedly connected to the fourth fixing ring 7, and the top surfaces of the first fixing ring 4 and the third fixing ring 6 are both provided with auxiliary suture openings 12.

[0038] Specifically, the combined fixing assembly includes a shaft rod 8, a clamping piece 9, a torsion spring 10 and a slot 11. The outer end of the second fixing ring 5 is fixedly connected to the shaft rod 8. Both ends of the shaft rod 8 extend to the outside of the left and right sides of the second fixing ring 5. The surface of the shaft rod 8 is rotatably connected to the clamping piece 9. The surface of the shaft rod 8 is sleeved with a torsion spring 10. The two ends of the torsion spring 10 are respectively fixedly connected to the clamping piece 9 and the second fixing ring 5. The top surfaces of the outer ends of the first fixing ring 4 and the third fixing ring 6 are provided with slots 11, and the top end of the clamping piece 9 is clamped in the middle of the slot 11.

[0039] Specifically, the number of combined fixing components is two, and the two groups of combined fixing components are respectively connected to the outer ends of the second fixing ring 5 and the fourth fixing ring 7 .

[0040] Specifically, the tendon docking mechanism 2 includes a rack 13, a plug-in slot 14 and a clamping assembly. The rack 13 is fixedly connected to the left side of the third fixing ring 6. The plug-in slot 14 is opened in the middle of the first fixing ring 4. The rack 13 and the plug-in slot 14 are plug-connected.

[0041] Specifically, the snap-on assembly includes an auxiliary shell 15, a support frame 16, a first lifting rod 17, a ring 18, a snap-on block 19 and a first spring 20. The top surface of the extended end of the first fixed ring 4 is fixedly connected with the auxiliary shell 15, the auxiliary shell 15 is connected to the middle of the plug-in slot 14, the middle of the auxiliary shell 15 is fixedly connected with the support frame 16, the middle of the support frame 16 is slidably connected with the first lifting rod 17, the top of the first lifting rod 17 is fixedly connected with the ring 18, the end of the first lifting rod 17 away from the ring 18 is fixedly connected with the snap-on block 19, and the surface of the first lifting rod 17 is sleeved with a first spring 20.

[0042] With the above structural design, when in use, first place the second fixing ring 5 and the fourth fixing ring 7 respectively under the ruptured tendons on both sides. After completion, flip the first fixing ring 4 and the third fixing ring 6 downwards so that the outer ends of the first fixing ring 4 and the third fixing ring 6 squeeze the clamping member 9. After being squeezed, the clamping member 9 flips outwards with the shaft 8 as the axis. At the same time, the torsion spring 10 stores elastic potential energy after being subjected to the rotating torsion. When the bottom surfaces of the first fixing ring 4 and the third fixing ring 6 respectively contact the top surfaces of the second fixing ring 5 and the fourth fixing ring 7, the torsion spring 10 releases the elastic potential energy to flip the top end of the clamping member 9 inwards, and then the top end of the clamping member 9 is clamped to the middle of the slot 11, thereby completing the fixation of the ruptured tendons on both sides. The rack 13 on the left side of the fourth fixing ring 7 is plugged into the inside of the plug-in groove 14. During the plugging process of the rack 13, the top surface continuously contacts the clamping block 19, and the clamping block 19 is pushed upward until the right side of the first fixing ring 4 contacts the left side of the third fixing ring 6. The clamping block 19 is pushed downward by the first spring 20 and clamped to the middle part of the rack 13, thereby completing the docking of the ruptured tendons on both sides. After that, the doctor can suture the tendons through the auxiliary suture openings 12 on the top surfaces of the first fixing ring 4 and the third fixing ring 6. After the suturing is completed, the clamping piece 9 is rotated and toggled around the shaft 8 as the axis, so that the top end of the clamping piece 9 is taken out from the middle part of the slot 11, and the first fixing ring 4 and the third fixing ring 6 can be flipped upward and removed.

[0043] Embodiment 2:

[0044] The tendon rupture auxiliary suture device provided in Example 1 is further optimized, specifically, as follows Figure 2-Figure 3 As shown, the clamping and adjusting mechanism 3 includes a second lifting rod 21, a tendon supporting tile 22, a limit plate 23 and a second spring 24. The second fixing ring 5 and the middle part of the fourth fixing ring 7 are both slidably connected with the second lifting rod 21, the top end of the second lifting rod 21 is fixedly connected with the tendon supporting tile 22, the end of the second lifting rod 21 away from the tendon supporting tile 22 is fixedly connected with the tendon supporting tile 22, and the surface of the second lifting rod 21 is sleeved with a second spring 24.

[0045] Specifically, the top surface of the tendon supporting tile 22 and the symmetrical surfaces of the first fixing ring 4 and the third fixing ring 6 are fixedly connected with silicone anti-slip strips. By providing the silicone anti-slip strips, the device can prevent sliding during the process of clamping the tendon.

[0046] Through the above-mentioned structural design, when the first fixing ring 4 and the second fixing ring 5 and the third fixing ring 6 and the fourth fixing ring 7 cooperate to clamp the tendon, the first fixing ring 4 and the third fixing ring 6 apply downward pressure. When the first fixing ring 4 and the third fixing ring 6 squeeze the tendon, the tendon is subjected to pressure and transmits the pressure to the tendon supporting tile 22. After being squeezed, the tendon supporting tile 22 pushes the second lifting rod 21 downward. When the tendon supporting tile 22 moves downward, it cooperates with the top surface of the second fixing ring 5 or the third fixing ring 6 to compress the second spring 24. When the second spring 24 is squeezed and contracted, it will form a reverse force on the tendon supporting tile 22, thereby stabilizing the tendon clamping.
