Description

Special connecting pipe for tracer injection in laparoscopic surgery

Technical Field

The utility model relates to the technical field of tracer injection, in particular to a connecting pipe special for tracer injection in laparoscopic surgery.

Background

Tracers are often used in tumor surgery to reveal lymph nodes, which is beneficial to increasing the number of lymph node cleaning. Commonly used tracers are mostly liquids, such as nanocarbons, indocyanine green, methylene blue, and the like. In the traditional open surgery, the tracer can be directly injected around the tumor by using the injector, but the laparoscopic tumor resection surgery is more and more common, the laparoscopic tracer injection is very inconvenient, the common injector cannot extend into the abdominal cavity, the existing endoscopic injection device is complex, a whole set of special equipment is needed, the common injector, a needle head and the like in medical treatment cannot be used, the increased medical cost is caused, and the use is complicated, so that the application of the tracer in the laparoscopic surgery is severely limited. At present, no simple laparoscopic connecting tube exists, and a common injector can be used for introducing a needle into the abdominal cavity for injection.

Disclosure of Invention

The utility model aims to provide a connecting pipe special for tracer injection in laparoscopic surgery, which aims to solve the problems in the background technology.

The technical scheme of the utility model is as follows: the utility model provides a special connecting pipe of tracer injection in laparoscopic surgery, includes syringe and connecting pipe, connecting pipe both ends fixedly connected with link one respectively and link two, the injection end and the link one fixed connection of syringe, the spiral line has been seted up to link two inside walls, link two pass through spiral line screw thread fixedly connected with syringe needle.

Preferably, the length of the connecting pipe is 40cm.

Preferably, the inner diameter of the connecting pipe is 1mm, and the outer diameter of the connecting pipe is 3mm.

Preferably, the diameter of the second connecting end is 3mm-9mm.

Preferably, the connecting pipe is made of plastic.

The utility model provides a special connecting pipe for tracer injection in laparoscopic surgery through improvement, which has the following improvement and advantages compared with the prior art:

1. the structure is simple, the plastic disposable connecting pipe is low in use cost;

2. the needle connecting end is of an internal spiral design, so that the needle can be screwed into the connecting end, the needle is prevented from falling off and falling into the abdominal cavity under the laparoscope while the tightness is ensured, and the safety is high;

3. the connecting end of the injector is of standard size, and the injector commonly used in the market can be connected with the injector;

4. the length of the connecting tube is 40cm, so that the length used under the laparoscope can be ensured, and the connecting tube is not overlong;

5. most of the tracers have smaller specification capacity, the inner diameter of the connecting pipe is smaller, and the residues of the tracers in the connecting pipe can be reduced;

6. the diameter of the connecting end of the connecting pipe needle head is 3mm-9mm, and the connecting pipe needle head can extend into the abdominal cavity by smoothly passing through a 10mm puncture outfit commonly used in laparoscopic surgery.
