Problems solved by technology

However, in actual operation, while turning the winding wheel 6 clockwise with the thumb of the right hand, the number of turns of the winding wheel 6 needs to be visually observed to confirm whether the ferrule 2 is placed on the bottom of the hemorrhoid before stopping the winding. Wire wheel 6, quite inconvenient to operate

Abstract

The invention provides a surgical ligation device which is of a gun shape. An inner cavity pipe is arranged in a gun barrel; an adsorption opening is formed at one end of a gun bore; the adsorption opening is sleeved with a ferrule; a guide groove is formed outside the gun barrel and used for accommodating a push rod; a boss is arranged at the other end of the gun bore, and the boss protrudes outwards to form a pressing part; a pressing spring is arranged in the pressing part; the pressing part can be pressed to push the push rod to move in the guide groove by means of the tensile force of the spring; a negative pressure suction pipe and an exhaust pipe connected with the side of the negative pressure suction pipe are arranged in a handle, so that an inner cavity pipe, the exhaust pipe and the negative pressure suction pipe are connected to form a closed space; when a suction device is connected, the inner cavity pipe, the exhaust pipe and the negative pressure suction pipe present the negative pressure and then the adsorption opening can adsorb a target object by means of the negative pressure; and after the target object is adsorbed, the push rod is pushed to move to the adsorption opening, so that the ferrule sleeving the adsorption opening is pushed away, and then the ferrule which is pushed away and falls down can sleeve the target object.

Description

technical field [0001] The invention belongs to the technical field of surgical medical instruments, in particular to a surgical ligation device. Background technique [0002] Hemorrhoid ligation (also known as hemorrhoid rubber ring ligation, hemorrhoid suction ligation, etc.) is a common method for the treatment of hemorrhoids. etc.) bandage the root (or base) of the hemorrhoid lesion tissue, thereby using the elastic retraction force of the rubber ring to block the blood supply of the hemorrhoid, making it necrotic, shrinking, and falling off, so as to achieve the purpose of healing. In the past, the traditional instruments used for ligation surgery were extremely simple, time-consuming, laborious, and prone to complications. [0003] Nowadays, most of the surgical ligation devices commonly used in hemorrhoid ligation operations are hand-held guns. This kind of ligation device can only work with negative pressure once to the end. Once the lesion tissue is not adsorbed in...
