Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a puncture device with a support. Background Technology

[0002] A trocar is an essential surgical instrument for abdominal examinations, abdominal surgery, and other minimally invasive or surgical procedures. A trocar creates an access channel in the abdominal wall, allowing laparoscopes or other surgical instruments (such as endoscopes, scissors, staplers, guidewires, catheters, filters, stents, etc.) to enter the abdominal cavity, and provides a passage for gas, facilitating surgical procedures.

[0003] For example, the disposable trocar cannula puncture device provided in Chinese Patent Application No. 202320898091.X is basically described as follows: It includes a trocar cannula puncture device body, on which a puncture tube is provided. A positioning structure is provided on the puncture tube. The positioning structure includes an adjusting ball and a fixing seat. The fixing seat has a ball hole. The adjusting ball is located within the ball hole and rotatably connected to it. The positioning structure's suction cup contacts the skin. Pressing the suction cup downwards expels the gas inside, thus fixing the positioning structure to the skin. Then, the trocar cannula puncture device body is held and the angle adjusted so that the adjusting ball is within the ball hole of the fixing seat. After rotating and adjusting the angle, tightening the screw locks the adjusting ball, preventing it from loosening and fixing the angle of the cannula trocar body. This allows for skin puncture at a fixed angle and facilitates specific surgical procedures. However, this device uses a suction cup to fix the trocar to the skin surface. Due to the roughness of the skin, gaps may exist between the suction cup and the skin, preventing the suction cup from adhering properly. Furthermore, air from the abdominal cavity can enter the bottom of the suction cup through the skin puncture hole, further increasing the probability of the suction cup loosening. This results in poor stability and a tendency for the trocar to loosen. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figs. 1-3This utility model provides a technical solution: a puncture device with a support, including a puncture tube 1 and a puncture needle 2 disposed inside the puncture tube 1. A puncture device body 3 is fixedly connected to the upper surface of the puncture tube 1, and the puncture needle 2 passes through the puncture device body 3. A connecting ring 4 is slidably fitted onto the top of the outer surface of the puncture tube 1. Three sets of support sleeves 5 are disposed on the outer side of the connecting ring 4. The connecting ring 4 and the support sleeves 5 are rotatably connected by a rotating component 6. A support rod 7 is slidably inserted into the inner wall of the support sleeve 5. An adhesive support 8 is rotatably connected to the bottom of the outer surface of the support rod 7. A push block 9 is fixedly connected to the top of the puncture needle 2. Through the cooperation of the puncture tube 1, connecting ring 4, support sleeves 5, support rods 7 and adhesive support 8, medical personnel can attach the bottom of the three sets of adhesive support 8 to the surface of the patient's skin using a double-sided adhesive layer 803. The support sleeves 5 and support rods 7 form a stable triangle with the puncture tube 1. The offset movement is restricted, and the puncture tube 1 can only move along the axis of the connecting ring 4, thereby further enhancing the positional stability of the puncture device body 3 and the puncture tube 1 during the operation. No additional personnel are needed to hold the puncture device body 3, reducing the workload of medical staff. In addition, the double-sided adhesive layer 803 is firmly connected to the skin, reducing the probability of the device falling over. Through the cooperation of the support sleeve 5, the clamping plate 501, the rotating part 6, the support rod 7 and the slot 701, medical staff can adjust the extension and retraction of the support rod 7 in the support sleeve 5, thereby adjusting the total support length of the support sleeve 5 and the support rod 7. The clamping plate 501 and the slot 701 can fix the position of the support rod 7. The support sleeve 5 can be rotated by the rotating part 6, so that the device can support and fix the puncture tube 1 inserted at any angle, further enhancing the applicability of the device and facilitating the operation of the staff.

[0022] In this utility model, in order to further facilitate the adjustment of the total length of the support sleeve 5 and the support rod 7, multiple sets of clamping plates 501 are fixedly connected to the bottom of the inner wall of the support sleeve 5, and multiple sets of slots 701 adapted to the clamping plates 501 are opened on the outer surface of the support rod 7. The distance between each set of clamping plates 501 is the same as the thickness of the clamping plates 501, so that the user can use the support rod 7 fixed by the clamping plates 501 and the slots 701 to facilitate the adjustment of the total length of the support sleeve 5 and the support rod 7.

[0023] In this utility model, in order to further facilitate the user to adjust the support angle of the support sleeve 5, the rotating component 6 includes a rotating seat 601 fixedly connected to the connecting ring 4.

The inner wall of the connecting ring 4 is provided with a limiting groove that matches the limiting strip. By cooperating with the limiting strip and the limiting groove, the rotation of the puncture tube 1 is prevented, thereby further enhancing the stability of the puncture tube 1.

[0026] In this invention, in order to further enhance the installation stability of the puncture tube 1, multiple sets of anti-slip rings are fixedly connected to the bottom of the outer surface of the puncture tube 1. The puncture tube 1 is made of medical transparent polypropylene. By setting the anti-slip rings, the probability of the puncture tube 1 sliding in the puncture hole is reduced, thereby further enhancing the installation stability of the puncture tube 1.

[0027] In use, align the bottom end of the puncture tube 1 with the skin, press the advance block 9, the puncture needle 2 punctures the patient's skin, pull out the puncture needle 2, insert the puncture tube 1 into the abdominal cavity, rotate the support rod 7 ninety degrees so that the cross-section of the support rod 7 is parallel to the locking plate 501, the locking plate 501 releases the locking of the locking groove 701, adjust the unfolding angle and the length of use of the support rod 7, rotate the support rod 7 ninety degrees again so that the locking plate 501 is locked into the locking groove 701, thereby fixing the extension of the support rod 7, peel off the release paper of the double-sided adhesive layer 803, and stick the double-sided adhesive layer 803 to the surface of the patient's skin, thereby completing the fixation of the device.
