Through the wound suturing auxiliary device 8, the outer wall of the tube body 3 is provided with a clamping block 7, and the tube body 3 is fixedly connected with the wound suturing auxiliary device 8 through the clamping block 7. Through the function of the clamping block 7, the wound suturing auxiliary device 8 has a detachable effect. The abdominal puncture fixing device 9, the other side of the outer wall of the tube body 3 is connected with the abdominal puncture fixing device 9 through a threaded rotation, and the threaded connection can not only play a fixing role, but also ensure the stability during the puncture process.
[0015] The wound suturing auxiliary device 8 includes a mounting plate 801, a rack 804 and a ball socket 811. A slot 802 is provided at one end of the mounting plate 801, and the slot 802 is cooperated with the block 7 on the tube body 2 to be connected. A slide rail 806 is provided at the other end of the mounting plate 801 away from the slot 802. A slider 805 is fixedly connected to one end of the rack 804. The rack 804 is slidably connected to the surface of the mounting plate 801 through the slider 805 and the slide rail 806. The rack 804 can move left and right through the slider 805 and the slide rail 806. A pull rod 807 is fixedly connected to the other end of the rack 804. The other end of the pull rod 807 passes through the inner wall of the mounting plate 801. The movement of the rack 804 can be controlled by pulling the pull rod 807 outside the mounting plate 801. A cam 810 is meshed and connected below the rack 804. The cam 810 is rotatably connected to a first fixed shaft 809 through a bearing. The shaft 809 is fixedly connected to the surface of the mounting plate 801, and the movement of the rack 804 drives the cam 810 with incomplete teeth. The ball socket 811 is fixedly connected to the mounting plate 801. A first arc groove 812 is opened above the ball socket 811, and the first arc groove 812 is arranged directly below the cam 810, and the cam 810 and the first arc groove 812 are in the same parallel plane. A ball head 813 is rotatably connected inside the ball socket 811. The ball socket 811 and the ball head 813 belong to a ball joint device. The ball head 813 can be adjusted at multiple angles, and the cam 810 can squeeze and fix the ball head 813 through the first arc groove 812. One end of the ball head 813 is fixedly connected to a second fixed shaft 814, and the other end of the second fixed shaft 814 is fixedly connected to a suture positioning tube 815. The ball head 813 can drive the suture positioning tube 815 to adjust at multiple angles through the second fixed shaft 814 to better cooperate with the suture of postoperative wounds.
[0016] The abdominal puncture fixation device 9 includes a sleeve shaft 901, and a fixing seat 902 is fixedly connected to the bottom of the sleeve shaft 901. The fixing seat 902 plays an auxiliary role in fixing and supporting the sleeve shaft 901. Fixing plates 904 are relatively arranged at both ends of the fixing seat 902. The fixing plate 904 is fixedly connected to the outer ring of the fixing seat 902. A needle hole 905 is opened on the surface of the fixing plate 904. According to actual conditions, the position to be fixed can be sewn and fixed through the needle hole 905.
[0017] A one-way valve 6 is arranged inside the tube head 2, and the one-way valve 6 is fixedly connected to the inner walls on both sides of the tube head 2. The puncture needle 4 also passes through the valve port of the one-way valve 6. The outer wall of the tube head 2 is penetrated by an air intake valve 5 connected to the cavity. When gas is transported into the abdominal cavity through the air intake valve 5, the one-way valve 6 can prevent the gas from flowing out, including after the puncture needle 4 is pulled out of the tube body 2, when other surgical instruments are used to enter the abdominal cavity from the tube body, the one-way valve 6 can also prevent the gas from flowing out, thereby ensuring the normal operation of the operation.
[0018] The fixing seat 902 has a second arc groove 903 on its surface. When suturing, the needle and thread can pass through the second arc groove 903 into the abdominal wall and also pass out from the other end of the second arc groove 903. Finally, when the tube body 3 is pulled out of the abdominal wall, the needle and thread are pulled upward to tighten, thereby achieving the effect of assisting in suturing the incision.
[0019] The other two ends of the fixing plate 904 are fixedly connected with a wrap 906 , and the wrap 906 is provided with a Velcro 907 , so that the fixing plate 904 is firmly fixed on the patient's abdomen through the wrap 906 and the Velcro 907 .
[0020] One end of the cam 810 is provided with an incomplete tooth meshing with the rack 804 , and the rack 804 meshes with the incomplete tooth, thereby driving the cam 801 to rotate.
[0021] Working principle: When in use, place the abdominal puncture fixation device 9 at the position where puncture is required, and fix it around the patient's abdomen with the wrapping tape 906 and the Velcro 907. According to the actual situation, the position that needs to be stabilized can be sewn and fixed through the needle hole 905. At this time, the puncture device can be picked up, and the tube body 3 and the puncture needle 4 can be inserted into the sleeve shaft 901. The knob tube head 2 is turned to move the tube body 3 and the puncture needle 4 downward. The threaded connection between the inside of the sleeve shaft 901 and the outside of the tube body 3 can not only play a guiding and fixing role, but also ensure stability during the puncture process. After the tube body 3 and the puncture needle 4 enter the abdominal cavity and reach a certain position, the top cover 1 can be twisted to be disassembled. Because the top cover 1 is fixedly connected to the puncture needle 4, the puncture needle 4 is also pulled out of the inner cavity of the tube head 2 and the tube body 3 when the top cover is removed. At this time, the air inlet valve 5 can input gas into the inner cavity of the tube head 2, and the gas passes through the tube body 3 through the tube head 2 and finally enters the abdominal cavity. A one-way valve 6 is designed in the tube head 2. When the puncture needle 4 is pulled out or other surgical instruments are used to enter the abdominal cavity from the tube body 3, the one-way valve can prevent gas from flowing out, thereby ensuring the normal operation of the operation. After the operation, the wound suturing auxiliary device 8 is used to assist in suturing the incision. The slot 802 of the mounting plate 801 is fixed to the block 7 outside the tube body 3, and the needle and thread for suturing the incision are passed through the suturing positioning tube 815. At this moment, the suturing positioning tube 815 can be adjusted at multiple angles through the rotation of the ball head 813 and the ball socket 811. After determining the angle position, the pull rod 807 is pulled outward to move the rack to one side through the slider 805 and the slide rail 806, and the upper end of the cam 810 is provided with incomplete teeth that mesh with the rack 804. The rack 804 is engaged with the incomplete teeth by the incomplete teeth. The teeth are fully engaged, thereby driving the cam 801 to rotate. Under the rotation of the cam 810, the ball head 813 can be squeezed and fixed through the first arc groove 812 opened at the bottom, and finally the suture positioning tube 815 is fixed. When suturing, the needle and thread can pass through the second arc groove 903 to pass through the abdominal wall, and also pass through the other end of the second arc groove 903. Finally, when the tube body 3 is pulled out of the abdominal wall, the needle and thread are pulled upward and tightened, thereby achieving the effect of assisting in suturing the incision, which can effectively reduce the difficulty of incision suturing in laparoscopic surgery and reduce the incidence of postoperative puncture hole hernia.
