reusable ligature

Abstract

The invention provides a loop ligature device capable of being repeatedly used. The loop ligature device comprises a shell, a negative pressure suction pump, a storage battery, a sucker, a straw, a push ring, a push rod, a storage tank and a trigger, wherein the front end of the storage tank is provided with a connector, the front end of the straw is communicated with the sucker, and the rear end of the straw is detachably inserted into a cylinder-shaped cavity, so that the straw is communicated with the storage tank. The loop ligature device is characterized in that an opening of the cylinder-shaped cavity on the connector is exposed to the outside, so that a user can replace the straw and the push rod conveniently, and the repeated use of the loop ligature device is realized. According to the loop ligature device provided by the invention, the connector connected with the straw is exposed to the outside, and a push block for driving the push rod is exposed to the outside, so that the straw and the push rod can be conveniently assembled and disassembled, the defect that the connector and the push block can not be seen clearly if being arranged inside the shell is overcome, further, the medical workers can conveniently use the loop ligature device, the medical cost is reduced, the materials are saved, the environment-protecting and energy-saving effects are good, the beneficial effects are obvious, and thus the application and promotion are easy.

Description

technical field [0001] The invention relates to a reusable ligation device, in particular to a reusable ligation device which is convenient for medical personnel to replace suction pipes and push rods. Background technique [0002] In the process of treating patients' hemorrhoids and polyps, rubber rings are usually used to ligate and inject drugs into the ligated tissues, so that the ligated tissues are separated from the human body under the action of the drugs to achieve the purpose of treatment and rehabilitation. Under the requirements of low cost and low consumption of medical appliances, it is undoubtedly a waste to use a set of treatment appliances for a patient in the past, which is not conducive to reducing the burden of seeing a doctor, but also causes waste of labor and materials. The ligature is a trend. [0003] For example, the patent document with the patent number CN201410595665.1 and the invention name "Combined Electric Banding Syringe" discloses a reusab...

Problems solved by technology

But the ligation syringe of this structure is extremely inconvenient in the process of replacing the suction tube and the push tube. Since the pushing block and the suction negative pressure connector are all located in the housing, the light in the housing is insufficient, and it is difficult for the user to see the suction tube clearly. The opening on the negative pressure connector makes it very inconvenient to replace the suction tube and push tube

[0004] In order to prevent human tissue fluid from being sucked into the negative pressure pump during the negative pressure suction process, a storage device needs to be installed between the negative pressure pump and the suction pipe. In the patent document of "Ligation Therapy Device", in order to prevent the inflow of tissue fluid, a first liquid storage tank and a spare liquid storage tank are arranged between the suction negative pressure pump and the suction pipe. Due to the use of two liquid storage tanks, it is clear It is very inconvenient, and even does not meet the disinfection effect required by medical treatment, so it is not suitable for repeated use
