Description

Technical Field

[0001] The invention belongs to the field of medical surgical instruments, and in particular relates to a liver hydatid removal suction device used in liver hydatid removal surgery. Background Art

[0002] Hepatic echinococcosis is still a zoonotic parasitic disease that is under national key monitoring. As people demand high-quality medical services, they also have higher requirements for the experience of seeking medical treatment. The treatment of echinococcosis has gradually shifted from open surgery to minimally invasive surgery, and the modified Troca puncture treatment is also a hot spot for minimally invasive treatment. However, the key point of all surgical treatments for echinococcosis (whether open surgery, laparoscopic surgery, or puncture surgery) is how to remove the "cold skin", "jelly" or "cheese"-like cyst contents in the most closed condition possible to ensure that no living contents remain or leak out. There are some solutions at present, but there are still many disadvantages. The first is fine needle aspiration, which uses a thin puncture cannula needle to suck out the liquid cyst contents, but the tough internal cyst cannot be removed; the second is to use a conventional hydatid cyst patented suction device for suction, but the suction effect is poor for viscous or large internal cysts, and it is easy to clog the tube and is almost impossible to complete; the third is to use a hydatid cyst exciser to remove the cyst contents by excision and suction, but because the device is limited by the design concept, the composition of the device is complex, the clogged tube is not easy to clean, and the disassembly and assembly are complicated.

[0003] The present application provides an efficient hydatid cyst resection device with an extremely simple structure, good use effect, easy operation, and easy disassembly and cleaning. The device is suitable for use in hospitals at all levels and is also easy to promote at home and abroad.

[0004] The present application provides a device for cutting and aspirating cystic cysts which has a simple structure, good use effect, is easy to use, and is easy to disassemble and clean. Summary of the invention

[0005] The technical problem to be solved by this patent is to provide a liver hydatid excision and suction device which has a simple structure, good use effect, is easy to use, and is easy to disassemble and clean.

[0006] To achieve the above object, the present invention provides the following technical solutions: A device for removing and aspirating hydatid cysts, characterized in that it comprises an outer tube 2 and a cutting tube 4, wherein the outer tube 2 is a tubular body with one end closed and the other end open, a side opening 1 is provided on the tube wall of the closed end of the outer tube 2, and the side opening 1 connects the inside and outside of the outer tube 2, and the cutting tube 4 is open at both ends, one end is connected to an external negative pressure device, and the other end is inserted from the open end of the outer tube 2, and can reciprocate in the outer tube 2, that is, one end of the cutting tube 4 reciprocates at the side opening 1 to achieve cutting and aspiration.

[0007] The side opening 1 is square.

[0008] As an improvement, one end of the cutting tube 4 placed inside the outer tube 2 is provided with a cutting edge 3 , and the other end can be connected to the negative pressure suction tube 7 through a connecting sleeve 6 .

[0009] As an improvement, a sealing rubber sleeve 8 is provided at the open end of the outer tube 2 . The sealing rubber sleeve 8 is a valve type, and the cutting tube 4 passes through the sealing rubber sleeve 8 and enters the outer tube 2 .

[0010] As an improvement, a water injection port 5 is provided on the outer tube 2, and the water injection port 5 is provided near the opening end. The water injection port 5 is used to inject concentrated salt water into the channel for soaking and ordinary salt water for flushing. The opening end of the outer tube 2 is provided with a sealing rubber sleeve 8.

[0011] As an improvement, a cleaning rod 9 is further provided, and the cleaning rod 9 can be inserted into the outer tube 2 to clear the blockage in the outer tube 2 .

[0012] When in use, the outer tube 2 is placed in the sac, and the part to be removed is sucked from the side opening 1 of the outer tube 2 to the area of ​​the outer tube 2, and then the cutting tube 4 is inserted. The other end of the cutting tube 4 is connected to a negative pressure suction device, and the part at the side opening 1 is removed through the cutting edge 3 of the cutting tube 4, and the contents of the sac are sucked out. If the outer tube is blocked, it can be cleaned with a matching cleaning rod 9, which is easy to operate.

[0013] The core of this application is to use coaxial cutting and coaxial negative pressure suction mode, which is simple in design and can efficiently remove the inner capsule of liver hydatid cyst, thereby significantly improving the efficiency of surgery. 1. Brand-new integrated design of coaxial cutting and coaxial negative pressure connection This application breaks the complex force transmission mode of the existing cutting tools for longitudinal cutting, and changes to a direct and efficient coaxial cutting mode. The cutting tube 4 is placed inside the outer tube, and the part to be cut enters the outer tube 2 from the side opening 1 of the outer tube 2. The cutting tube 4 and the outer tube 2 reciprocate, and the cutting can be completed when the cutting edge at one end of the cutting tube 4 reciprocates at the side opening 1 of the outer tube 2. The contents after cutting are directly sucked out by the negative pressure suction device coaxially connected to the cutting tube 4, avoiding the longitudinal negative pressure sucking out of the contents, and having the advantages of simple operation and high efficiency. While operating, the water injection pipeline can be connected to avoid blockage.

[0014] 2. Simplify disassembly, cleaning, flushing and disinfection Due to its simple design, the equipment is easy to disassemble. If blockage occurs, the matching cleaning rod 9 can be used to easily clear the blockage, and it is easy to flush to avoid residual contents, which greatly improves the cleaning effect.

[0015] 3. Wide range of applications The equipment is suitable for various laparotomy, laparoscopy, puncture and other surgical operations and operations for various types of echinococcosis, and is suitable for promotion and use in grassroots hospitals. BRIEF DESCRIPTION OF THE DRAWINGS
