Problems solved by technology

At present, the pull-wire type multi-ring ligation device is mainly produced by COOK Company of the United States and Boston Scientific Company of the United States. Other Treatments for Working Pores
Hydraulic ligation devices, including single-ring ligation devices produced in Japan, can only ligate one part each time they enter the endoscope, and need to withdraw from the endoscope and reinstall the ligation ring again. The disadvantage is that the operation time is long and the patient is painful Big

Embodiment Construction

[0012] Referring to the accompanying drawings, the multi-ring ligation device of the present invention includes a ligation device 2 that can be connected with a medical endoscope 1 and a quantitative liquid adder 3 that can be connected with the ligation device 2 . The ligation device 2 is composed of a hollow sleeve 6 with a step and an outer tube sleeve 5 which is installed in sliding fit with the hollow sleeve 6 . The inner diameter of the perforation at the closed end of the outer sleeve 5 matches the outer diameter of the extension section of the hollow sleeve 6, and the inner diameter of the inner wall of the outer sleeve 5 matches the outer wall size of the step of the hollow sleeve 6 so that the outer wall of the hollow sleeve 6 matches the outer diameter of the outer sleeve 5. An airtight liquid storage bin 8 is formed between the inner walls. The hollow sleeve 6 is embedded with the medical endoscope 1 . The hollow sleeve 6 can be installed with a plurality of medic...

Abstract

The invention elates to a polycyclic ligating device for curing human body varices of esophagus stomach base which comprises ligating device which can connect with medical endoscope and quantitative feeder which can connect with ligating device. It comprises the following characters: the ligating device is formed by hollow cover with stages and outer pipe cover to match the slide of hollow cover. It forms a sealed liquid storage hopper between the out wall of hollow pipe and the inner wall of outer pipe cover. The hollow cover is half-lap jointed with medical endoscope; many medical rubber rings are fixed in turn on the extensive section of hollow cover beside outer pipe cover. When quantitative feeder fills certain of liquid into liquid storage hopper, the outer pipe cover can make the medical rubber rings defoliating in turn so as to achieve polycyclic ligating of varicosity.

Description

technical field [0001] The invention belongs to medical devices, in particular to a ligation device for treating varicose veins of the human esophagus and gastric fundus. Background technique [0002] my country is a high-incidence area of ​​hepatitis B virus infection. The prevalence rate accounts for 10% of the entire population, some patients turn into chronic hepatitis B, and finally develop into cirrhosis. The most common complication is esophageal and gastric varices, and rupture and bleeding of esophageal and gastric varices is the most common cause of death in patients. Therefore, the treatment of esophageal and gastric varices has become a key factor to prolong the survival time and improve the quality of life of patients. Endoscopic direct ligation of esophageal and gastric varices is an effective method for the treatment of esophageal and gastric varices. [0003] The working principle of the ligation device under the endoscope: This principle is the basic meth...
