Anorectal ligation device

Abstract

The invention discloses an anorectal ligation device. A left handle and a right handle are subjected to ultrasonic fusion welding; a gun rod comprises an inner cavity tube and an outer sleeve; a suction nozzle is connected to the front end of the inner cavity tube; the back side of the inner cavity tube is inserted into a tee tube and is fixed by virtue of a fixed clamping seat; a rear port of the inner cavity tube is connected with a first nozzle of the tee tube; a second nozzle of the tee tube is connected to a negative-pressure suction connector at the lower ends of the handles; the negative-pressure suction connector is connected to a negative-pressure source; a third nozzle of the tee tube is provided with a plug which is connected to a negative-pressure release switch on the side faces of the handles; the outer sleeve sleeves the inner cavity tube; a push sleeve is connected to the front end of the outer sleeve; the front side of the push sleeve is close to the suction nozzle and is capable of sliding forward along the suction nozzle; a ligation ring sleeves an outer circle at the front end of the suction nozzle; a guide block is fixedly connected to the back end of the outer sleeve; a spring is arranged between the guide block and the front end of the handle; and the lower end of the guide block is in transmitted connection to a trigger switch which is arranged on the handle. The anorectal ligation device achieves automatic implementation in a whole process of ligation treatment; the anorectal ligation device are safer to patients; a surgical operation can be completed by a single person within a short time; and after diagnosis and treatment, the probability of complications is low.

Description

technical field [0001] The invention relates to an anorectal ligation device. Background technique [0002] Although ligation staplers are widely used in the market, complications such as postoperative bleeding, stenosis, and rubber ring loosening are far from being resolved, especially the complications caused by the operation method are the main reasons for medical disputes. [0003] At present, ligation of hemorrhoids has become a standard treatment method. One of the methods of ligation is manual ligation. The equipment is simple, the method is backward, expensive, laborious, and difficult to operate. It requires the cooperation of multiple people to complete the operation. Generally, local anesthesia is required. , Due to the pain of operation and lesion exposure, it is easy to cause complications, such as ligation with silk thread, due to lack of elastic contraction or excessive cutting effect, it is easy to cause bleeding. The other is to use a ligation device. The l...

Problems solved by technology

[0004] The disadvantage of the ligation device with this structure is that the control of the suction piston and the ligation rubber ring pusher is all manually controlled by the operator, and both hands are required to operate at the same time, resulting in troublesome operation and long operation time

A series of problems due to the long operation time
