[0002] Minimally invasive surgery is a branch of medical science that uses minimally invasive procedures or incisions to deliver specialized instruments, physical energy, or chemical agents into the human body to perform surgical operations such as inactivation, resection, repair, or reconstruction of lesions, deformities, and injuries in order to achieve therapeutic goals. Its characteristic is that it causes significantly less trauma to patients than traditional surgery.

[0003] Suturing devices are commonly used in minimally invasive surgical procedures. However, the length between the suture head and the device is fixed and cannot be adjusted according to the actual situation, which reduces the adaptability of the device. In addition, existing suture devices generally do not have a device for disinfecting the wound, which causes some inconvenience. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. By utilizing the threaded connection between the threaded rod and the connecting block, multiple connecting blocks can be moved, causing the sleeve to move. This changes the length between the sleeve and the fixed rod, thereby changing the length between the suture head and the device body, improving the adaptability of the device. This invention provides a minimally invasive surgical suturing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Preferably, the disinfection mechanism includes a fixing block disposed at the upper end of the suture head, and the side wall of the fixing block is provided with two symmetrically arranged atomizing nozzles.

[0009] Preferably, the upper end of the device body is provided with a liquid storage tank, the side wall of the liquid storage tank is provided with a pump, the output shaft end of the pump is provided with a pipe, the outer wall of the pipe is provided with a corrugated pipe, and the end of the pipe is connected to two atomizing nozzles.

[0010] Preferably, a connecting groove is formed between the plurality of grooves, and gears are provided on the outer walls of the plurality of threaded rods, with the plurality of gears located within the connecting groove.

[0011] Preferably, a rotating ring is rotatably connected to the outer wall of the fixed rod, and a toothed ring is provided at the end of the rotating ring, with multiple gears meshing with the toothed ring.

[0012] The beneficial effects of this utility model are:

[0013] 1. By utilizing the threaded connection between the threaded rod and the connecting block, multiple connecting blocks can be moved, causing the sleeve to move. This changes the length between the sleeve and the fixed rod, thereby changing the length between the stitching head and the device body and improving the adaptability of the device.

Connecting blocks 17 are slidably connected within each of the multiple grooves 16, and each of the multiple connecting blocks 17 is connected to the inner wall of the sleeve 9. Each of the multiple grooves 16 is provided with a moving mechanism for moving the sleeve 9. The moving mechanism includes a threaded rod 18 rotatably connected within the groove 16, the threaded rod 18 passing through and threadedly connected to the connecting block 17. By utilizing the threaded connection between the threaded rod 18 and the connecting block 17, the multiple connecting blocks 17 move, causing the sleeve 9 to move, thereby changing the length between the sleeve 9 and the fixing rod 10, achieving a change in the length between the suture head 8 and the device body 1, and improving the adaptability of the device.

[0022] The suture head 8 is equipped with a disinfection mechanism, which includes a fixing block 11 located at the upper end of the suture head 8, and two symmetrically arranged atomizing nozzles 12 on the side wall of the fixing block 11.
