[0036] Specifically, in this embodiment, the wound suturing device includes a storage rack 6, and the positioning bracket 1 is arranged on the storage rack 6, and the storage rack 6 is used to place medical materials.

[0037] See also Figure 2As a preferred embodiment of the present invention, it may also have the following additional technical features: the translation mechanism 2 includes a first driving motor 21, a driving wheel 22, a driven wheel 23, a conveyor belt 24, a connecting block 25 and a sliding rail 26. The first driving motor 21, the driving wheel 22, the driven wheel 23 and the sliding rail 26 are respectively fixedly connected to the positioning bracket 1, the output end of the first driving motor 21 is fixedly connected to the driving wheel 22, the driven wheel 23 is arranged at an end of the positioning bracket 1 away from the driving wheel 22, the conveyor belt 24 is sleeved on the driving wheel 22 and the driven wheel 23, the connecting block 25 is fixedly connected to the conveyor belt 24, and the connecting block 25 is slidably connected to the sliding rail 26.

Through the sliding cooperation between the cavity 321 and the piston 34 inside it, the piston 34 slides up and down in the cavity 321, thereby driving the piston rod 33 and the fixed plate 35 to perform lifting and lowering movements, so that the suturing device can accurately reach different depths of the wound for suturing. The fixed plate 35 serves as the end supporting component of the lifting mechanism 3 and is fixedly connected to the fixed cylinder 41, providing stable support for the entire suturing device, ensuring the stability and reliability of the suturing device during the lifting process, and avoiding suturing errors caused by shaking or tilting.

[0039] See also Figure 4-Figure 7As a preferred embodiment of the present invention, it may also have the following additional technical features: the rotating assembly 43 includes a connecting shaft 431 and a rotating disk 432, the outer wall of the movable cylinder 42 is provided with two first openings 421, the connecting shaft 431 is movably connected to the two first openings 421, the rotating disk 432 is connected to both ends of the connecting shaft 431, and the rotating disk 432 is provided with a first inclined groove 4321 and a second inclined groove 4322 on one side close to the connecting shaft 431, and the positioning assembly 44 can be movably connected to the first inclined groove 4321 and the second inclined groove 4322 respectively.

[0040] As a preferred embodiment of the present invention, it may also have the following additional technical features: the positioning assembly 44 includes a first slide rail 441, a pushing block 442, an elastic member 443 and a positioning member 444, the first slide rail 441 is connected to the inner wall of the movable cylinder 42, two pushing blocks 442 are provided and are slidably connected to the first slide rail 441 in the first slide rail 441, each pushing block 442 is connected to a locking rod 445, the locking rod 445 is plugged into the first inclined groove 4321, one end of each pushing block 442 away from the rotating disk 432 is fixedly connected to the elastic member 443, one end of the elastic member 443 away from the corresponding pushing block 442 is fixedly connected to the positioning member 444, a second opening 422 is provided at one end of the movable cylinder 42, and the positioning member 444 passes through the second opening 422 and is clamped and connected to the suturing assembly 5. In this embodiment, the elastic member 443 is configured as a spring. When the suturing assembly 5 needs to be clamped, the suturing assembly 5 is placed between the positioning members 444, the rotating disk 432 is rotated, and the pushing block 442 moves in the first inclined groove 4321. The first inclined groove 4321 has a certain slope. When the pushing block 442 moves along the first inclined groove 4321, the pushing block 442 moves away from the rotating disk 432, and a force is applied to the elastic member 443. The elastic member 443 is compressed to apply a force to the positioning member 444. The positioning member 444 clamps the suturing assembly 5. As the rotating disk 432 continues to rotate, the pushing block 442 moves relatively to the second inclined groove 4322, the second bevel 4322 has a certain slope and is in the opposite direction to the first bevel 4321. When the pushing block 442 enters the second bevel 4322, the position of the pushing block 442 is fixed to complete the clamping of the suturing assembly 5. When the suturing operation is completed, the rotating disk 432 is rotated in the opposite direction, and the pushing block 442 moves in the second bevel 4322. When the pushing block 442 returns to the position of the first bevel 4321, the distance between the pushing block 442 and the rotating disk 432 is shortened, and the elastic member 443 applies a force to the positioning member 444 to separate the positioning member 444, thereby completing the disassembly of the suturing assembly 5.

When fixing the suture 53, first pass one end of the suture 53 through the perforation in the support 51, then pass the suture 53 through the positioning ring 542, then pass the suture 53 through the connecting ring 543 and tie the suture 53 to fix it on the connecting ring 543, and then press the limiting mechanism to fix the suture 53.

[0044] As a preferred embodiment of the present invention, it may also have the following additional technical features: the limiting structure 545 includes a limiting cover 5451, a connecting column 5452 and a plurality of extrusion rings 5453, the connecting column 5452 is fixedly connected to the limiting cover 5451, the connecting column 5452 is adapted to the aperture of the positioning ring 542, and each extrusion ring 5453 is evenly and equidistantly arranged on the side wall of the connecting column 5452, and an anti-slip part 5454 is arranged at one end of the limiting cover 5451 close to the positioning ring 542. Insert the connecting column 5452 into the inner cavity of the positioning ring 542, and then put the limiting cover 5451 on the outer periphery of the positioning ring 542 away from the end of the threaded rod 541, and the suture 53 is initially fixed by passing the suture 53 through the connecting ring 543 and knotting it to fix it on the connecting ring 543, and then the suture 53 is clamped and fixed by the squeezing ring 5453. When the threaded rod 541 is connected to the thread groove on the support seat 51 through threads, during the process of screwing in, the bottom wall of the thread groove gradually squeezes the limiting cover 5451, so that the anti-slip part 5454 squeezes and clamps the suture 53, so that the suture 53 can be fixed multiple times, thereby ensuring the fixing effect.

[0045] See also Fig.11 As a preferred embodiment of the present invention, it may also have the following additional technical features: the suture 53 includes a thread body 531 and an auxiliary layer 532, the auxiliary layer 532 is used to assist wound healing, the auxiliary layer 532 is wrapped around the thread body 531, and a plurality of micropores 5321 are provided on the auxiliary layer 532, and each micropore 5321 is arranged in a spiral linear manner, and each micropore 5321 can load a growth healing factor. In this embodiment, the depth of each micropore 5321 is 60-300nm. If its depth is less than 60nm, the loaded growth factor is too little, and it is difficult to effectively shorten the healing time. If its depth is greater than 300nm, it will affect the strength of the surgical suture 53, making it easy to break. Preferably, the depth of the micropores 5321 is 200-250nm; the pore size of the micropores 5321 is 450-1300nm. If the pore size is less than 450nm, the growth factor solution is difficult to effectively infiltrate; if the pore size is greater than 1300nm, the number of micropores 5321 that can be distributed in the auxiliary layer 532 is reduced, and the amount of growth factor solution that can be loaded is reduced. Preferably, the pore size of the micropores 5321 is 800-1000nm.

[0046] The working principle of the wound suturing device of this embodiment is as follows: the medical staff first evaluates the position, size and shape of the wound, determines the suturing strategy, selects multiple suitable suturing points around the wound, places the device above the wound, adjusts the positioning bracket 1 to ensure that the device maintains an appropriate distance and angle with the wound, selects a suitable suturing needle 52 and suture thread 53 according to the needs of the wound, and installs them on the suturing assembly 5. The medical staff operates the first driving motor 21 to accurately control the moving speed and direction of the conveyor belt 24, so that the connecting block 25 drives the entire lifting mechanism 3 to move above the wound, and then controls the lifting mechanism 3 to move the suturing needle 52 downward and accurately pierce the skin next to the suturing point. The medical staff rotates the movable cylinder 42 to make the suturing needle 52 pass through the wound and reach the opposite skin. Then the lifting mechanism 3 is controlled to rise, at which time the suture thread 53 pulls the wound together and sutures it. After completing the first suture point, the medical staff needs to repeat the above steps, move the device to the next selected suture point, and perform the suture operation until the wound is completely sutured. When all the selected suture points are sutured, the medical staff needs to check the suture condition of the wound to ensure that the suture thread 53 is even, tight and not loose.

[0047] The wound suturing device of the present embodiment has a reasonable structural design and is easy to use. This structure can also be used for other devices with similar usage requirements. In the present embodiment, the wound suturing device can effectively reduce the physical exertion and soreness and fatigue of medical staff during the suturing process, allowing them to focus more on the suturing operation, improving the efficiency and quality of the operation. Through the synergistic effect of various mechanisms, the accurate positioning and stable operation of the suturing needle 52 are ensured, reducing suturing errors caused by human factors.
