DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-5 , this utility model provides a technical solution:

[0028] A disposable abdominal puncture device includes a tube handle 1, the bottom of the tube handle 1 is connected to a cannula 2, the top of the tube handle 1 is provided with a puncture handle 3, the bottom of the puncture handle 3 is provided with a puncture needle 4, and the puncture needle 4 passes through the interior of the cannula 2. The right side of the tube handle 1 is connected to an inflation valve 5, and the bottom of the outer side of the cannula 2 is provided with an auxiliary fixing component 6. The auxiliary fixing component 6 includes a positioning ring 601 sleeved on the outer side of the cannula 2, and the top of the outer side of the cannula 2 is provided with a positioning component 7;

[0029] The positioning assembly 7 includes an external thread 701, a length mark 702, an adjustment ring 703 and a magnet piece 704. The external thread 701 is opened on the outside of the sleeve 2, the length mark 702 can be on the front side of the sleeve 2, the adjustment ring 703 is sleeved on the outside of the sleeve 2, the inside of the adjustment ring 703 is threadedly connected to the external thread 701, and the magnet piece 704 is bonded to the bottom of the adjustment ring 703.

[0030] In this embodiment: the auxiliary fixing component 6 is first sleeved on the outside of the sleeve 2, and then when the puncture needle 4 enters the abdominal cavity, the auxiliary fixing component 6 is adsorbed on the outside of the puncture position. Then, before puncture, according to the patient's specific situation and surgical requirements, the adjustment ring 703 is accurately rotated with reference to the length number 702 to determine the predetermined depth of the puncture needle 4 entering the abdominal cavity. Then, the puncture needle 4 is inserted into the patient's abdominal cavity along the sleeve 2. When the magnet piece 704 at the bottom of the adjustment ring 703 contacts and adsorbs the top of the auxiliary fixing component 6, it indicates that the puncture needle 4 has reached the predetermined puncture depth. At this time, the auxiliary fixing component 6 provides support and limitation for the puncture device, and the adjustment ring 703 is fixed by adsorption with the positioning ring 601 and the threaded connection between itself and the sleeve 2, thereby stabilizing the puncture depth of the puncture needle 4 and ensuring that the operation is carried out safely and accurately.

[0031] Specifically, such as Figure 2 As shown, a magnetic sheet 602 is bonded to the top of the positioning ring 601 , and the magnetic sheet 602 is magnetically connected to the magnet sheet 704 .

[0032] Specifically, such as Figure 2 As shown, the interior of the positioning ring 601 is rotatably connected to an auxiliary rotating bead 603 , and the auxiliary rotating bead 603 is located on the outside of the sleeve 2 .

[0033] Specifically, such as Figure 2 As shown, the triangles at the bottom of the positioning ring 601 are fixedly connected to suction cups 604, and the suction cups 604 are made of sterile food-grade rubber material.

[0034] In this embodiment: the sterile suction cup 604 at the bottom of the positioning ring 601 is adsorbed on the patient's abdominal skin, and then during the puncture process, the auxiliary rotating bead 603 inside the positioning ring 601 reduces the friction resistance between the sleeve 2 and the positioning ring 601. After the puncture is in place, when the magnet sheet 704 at the bottom of the adjustment ring 703 contacts and adsorbs the magnetic sheet 602 at the top of the positioning ring 601, it indicates that the puncture needle 4 has reached the predetermined puncture depth, ensuring that the operation is carried out safely and accurately.

[0035] Specifically, such as Figure 3 As shown, the triangles on the outside of the adjustment ring 703 are fixedly connected to the rotating rod 8, and the outside of the rotating rod 8 is arc-shaped.

[0036] Specifically, such as Figure 3 As shown, the surface of the rotating rod 8 is provided with anti-skid lines, and the anti-skid lines are in a grid shape.

[0037] In this embodiment: the adjustment ring 703 can be easily rotated by rotating the rotating rod 8, making the adjustment process simpler and faster, saving surgical preparation time, and the grid-shaped anti-slip texture on the surface of the rotating rod 8 increases the friction between the fingers and the rotating rod 8. When rotating the rotating rod 8 to adjust the puncture depth, it can effectively prevent the fingers from slipping, making the rotation of the adjustment ring 703 more precise and controllable, ensuring that the puncture needle 4 can accurately reach the predetermined puncture depth.

[0038] Specifically, such as Figure 5 As shown, a biological adhesive pad 9 is fixedly connected to the bottom of the sleeve 2 , and the biological adhesive pad 9 is located outside the puncture needle 4 .

[0039] Specifically, such as Figure 5 As shown, a digital display ring is engraved on the surface of the sleeve 2, and the digital display ring is located at the bottom of the length mark 702.

[0040] In this embodiment: the biological adhesive pad 9 can effectively fill the gap between the puncture site and the sleeve 2, thereby enhancing the sealing of the puncture site, reducing the risk of gas leakage in the abdominal cavity and invasion of external bacteria, reducing the incidence of abdominal infection, and providing safety protection for the operation. In addition, the digital display ring engraved on the surface of the sleeve 2 is located at the bottom of the length mark 702. When performing the puncture operation, the digital display ring can provide the doctor with an accurate digital scale reference, so that the doctor can more accurately judge the depth of the puncture needle 4 entering the abdominal cavity, thereby improving the accuracy of the puncture depth measurement.

[0041] Working principle: When the disposable abdominal puncture device is in use, the sterile suction cup 604 at the bottom of the positioning ring 601 is adsorbed on the patient's abdominal skin. Then, before puncture, according to the patient's specific situation and surgical requirements, the adjustment ring 703 is accurately rotated with reference to the length number 702 to determine the predetermined depth of the puncture needle 4 entering the abdominal cavity. Then, the puncture needle 4 is inserted into the patient's abdominal cavity along the cannula 2. During this process, the auxiliary rotating bead 603 inside the positioning ring 601 reduces the friction resistance between the cannula 2 and the positioning ring 601. Then, after the puncture is in place, when the magnet piece 704 at the bottom of the adjustment ring 703 contacts and adsorbs with the magnetic piece 602 at the top of the positioning ring 601, it indicates that the puncture needle 4 has reached the predetermined puncture depth, ensuring that the operation is carried out safely and accurately.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
