Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a puncture needle specially used for cholecystobiliary puncture, aiming to improve the efficiency and safety of the operation. Background Art

[0002] Laparoscopic cholecystobiliary puncture is an important means commonly used in clinical surgery to decompress the gallbladder and bile duct, and to qualitatively identify and collect bile for bacterial culture and drug sensitivity testing.

[0003] Conventional laparoscopic gallbladder puncture needles have the following problems: 1. The puncture needle is a one-piece metal structure, and the needle tip becomes dull after a period of use. The needle is also thick, making it difficult to puncture the bile duct (because the thick needle causes greater damage after puncture). Sometimes the bile duct is difficult to identify during surgery, so puncture is required for qualitative analysis. Currently, there are no laparoscopic bile duct puncture needles available. 2. The original laparoscopic gallbladder puncture needle: Because the needle is a one-piece metal structure, the needle easily becomes blunt after repeated use, causing greater damage during puncture and easy bleeding. It is also difficult to puncture the thick gallbladder wall. It is not always available, which is inconvenient.

[0004] Patent application number CN201822125577.1 discloses a disposable catheter specifically for biliary drainage, comprising a cannula, an injection needle, and a puncture needle. The cannula is fixedly connected to an injection needle on one side, and a puncture needle on the other side. A Velcro patch is fixedly connected to the surface of the cannula, and the fixing buckle and the tube head are fixedly connected via a connecting line. In this utility model, a tightening wire and a hook are provided. The hook hooks into the wall of the straight tube to help fix the tightening wire. The tightening wire helps fix the curved tube by tightening, reducing tension to maintain stable air pressure in the body, reducing shaking of the curved tube, and improving safety and stability. A fixed shaft, a fixing buckle, and an anti-slip sleeve are provided. The fixing buckle helps fix the protective sleeve, and the anti-slip sleeve prevents the straight tube from slipping, reducing the risk of slipping. A Velcro patch is provided. The adhesive layer in the Velcro patch sticks to external objects, and the fixing layer helps fix the Velcro patch to the tube head, improving the stability of the tube head.

[0005] However, the above patented technology cannot be applied to cholecystobiliary puncture, and cannot solve the technical problems existing in the prior art. Utility Model Content

[0006] The purpose of this utility model is to provide a laparoscopic gallbladder and bile duct puncture needle to solve the problems raised in the above background technology:

[0007] (1) How to improve the structure of the puncture needle to achieve puncture decompression and sampling of the gallbladder and bile duct, and to instantly judge the properties of the puncture fluid through visual design, thereby improving the accuracy and safety of the operation.

[0008] To achieve the above objectives, the present invention provides the following technical solutions:

[0009] A laparoscopic gallbladder and bile duct puncture needle;

[0010] It includes an aspirator tube body, a front injection component and a negative pressure mechanism;

[0011] The front-end injection assembly includes a front-end needle and a front-end syringe. The front-end needle is fixed on the front side of the front-end syringe. The front-end syringe is made of transparent material. The rear end of the front-end syringe is connected to the front end of the suction tube body, and the rear end of the suction tube body is connected to the negative pressure mechanism on the rear side.

[0012] On the basis of the above technical solution, the present invention can also be improved as follows.

[0013] Furthermore, the rear end of the front syringe is detachably connected to the front end of the aspirator tube body.

[0014] Furthermore, a quick connection connector is provided at the rear end of the suction tube body.

[0015] Furthermore, the negative pressure mechanism is a negative pressure aspirator, and the inlet of the negative pressure aspirator cooperates with the quick connection connector of the aspirator tube body.

[0016] Furthermore, the negative pressure mechanism is a disposable syringe, and the syringe port of the disposable syringe cooperates with the quick connection connector of the aspirator tube body.

[0017] Furthermore, the negative pressure mechanism uses a disposable syringe with a specification of 20 ml.

[0018] Furthermore, the front end syringe of the front end injection assembly is a disposable syringe syringe with a specification of 1 ml.

[0019] After adopting such a structure, the aspirator tube serves as the main part of the puncture needle, connecting the front injection component and the negative pressure mechanism, and is responsible for guiding the flow of the puncture fluid.

[0020] The front-end injection assembly consists of a front-end needle and a front-end syringe. The front-end needle is fixed to the front side of the front-end syringe and is used for puncture. The front-end syringe is made of transparent material to facilitate intraoperative observation of the puncture fluid color to distinguish blood from bile, etc. The front-end syringe is preferably a 1ml disposable syringe to ensure sufficient visual clarity and operational flexibility. The rear end of the front-end syringe is detachably connected to the front end of the aspirator tube for easy replacement.

[0021] Two implementation methods are provided for the negative pressure mechanism: one is to use a negative pressure suction device as the negative pressure source, and its inlet is tightly matched with the quick-connect connector at the rear end of the suction device tube to provide a continuous and stable negative pressure environment; the other is to use a disposable syringe with a specification of 20ml as a simple negative pressure device, and its syringe port is also compatible with the quick-connect connector, which is suitable for emergency or simple surgical scenarios, and has the advantages of low cost and easy operation.

[0022] During use, this laparoscopic gallbladder and bile duct puncture needle can puncture the gallbladder to decompress it and collect bile for bacterial culture. If the bile duct is unclear during surgery, the bile duct can be punctured to clarify it, reduce pressure, determine the bile's properties, and collect bile for bacterial culture. The transparent front end of the syringe allows for immediate and clear visualization of the puncture fluid (red for blood, yellow for bile), allowing the color of the puncture fluid to confirm whether it is a bile duct.

[0023] The beneficial effects of this laparoscopic gallbladder and bile duct puncture needle are:

[0024] (1) It integrates suction, injection and visualization functions into one, significantly improving the convenience and accuracy of surgical operations.

[0025] (2) The transparent front-end syringe design enables immediate judgment of the properties of the puncture fluid during surgery, reducing the risk of misoperation.

[0026] (3) The negative pressure mechanism can be equipped with a negative pressure aspirator or a disposable syringe to meet the needs of different surgical scenarios and increase the flexibility of use.

[0027] (4) The structure is reasonably designed, which facilitates disinfection and replacement of parts, ensuring the safety and hygiene standards of the operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Example 1

[0036] See also Figure 1 .

[0037] The laparoscopic gallbladder and bile duct puncture needle comprises an aspirator tube body 200 , a front injection component and a negative pressure mechanism 300 .

[0038] The front-end injection assembly includes a front-end needle 110 and a front-end syringe 120. The front-end needle 110 is fixed to the front side of the front-end syringe 120. The front-end syringe 120 is a disposable syringe with a specification of 1 ml, and the front-end syringe 120 is transparent.

[0039] The suction tube body 200 uses the tube body of a conventional laparoscopic suction tube, and the rear end of the front syringe 120 is detachably connected to the front end of the suction tube body 200. The rear end of the front syringe 120 is connected to the front end of the suction tube body 200, and the rear end of the suction tube body 200 is provided with a quick connection connector 210.

[0040] The negative pressure mechanism 300 is a disposable syringe, the syringe port of which is matched with the quick connection connector 210 of the aspirator tube body 200. The disposable syringe of the negative pressure mechanism 300 is a disposable syringe with a specification of 20 ml.

[0041] During the operation, first select the appropriate negative pressure mechanism 300 according to the needs, and connect it to the aspirator tube body 200 through the quick-connect connector 210. Install the front-end injection assembly to the front end of the aspirator tube body 200 to ensure a firm connection. Use the front-end needle 110 to accurately puncture the gallbladder or bile duct, and at the same time turn on the negative pressure mechanism 300 to aspirate the puncture fluid. By observing the color of the puncture fluid in the transparent front-end syringe 120, it can be quickly determined whether it is blood or bile to guide subsequent surgical operations. After completing the puncture sampling, the puncture needle can continue to be used for decompression or further exploration as needed.

[0042] The laparoscopic gallbladder and bile duct puncture needle can puncture the gallbladder to decompress it and collect bile for bacterial culture. If the bile duct is unclear during surgery, the bile duct can be punctured to clarify it, reduce pressure, determine the characteristics of the bile, and collect bile for bacterial culture.

[0043] Example 2

[0044] See also Figure 2 .

[0045] The only difference between this embodiment and the first embodiment is that the negative pressure mechanism is a negative pressure suction device 400 , and the inlet of the negative pressure suction device 400 cooperates with the quick connection connector 210 of the suction device tube body 200 .

[0046] This embodiment utilizes a negative pressure aspirator to decompress the gallbladder and extract bile, thereby reducing manual manipulation of the patient's organs and lowering safety risks.

[0047] The above are only two embodiments of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the principles of the present invention, and these should also be regarded as falling within the scope of protection of the present invention.
