Anorectal loop ligature anastomat with accurate and controllable stroke

Abstract

The invention discloses an anorectal loop ligature anastomat with accurate and controllable stroke. The anorectum loop ligature anastomat comprises a holding handle with the interior being of a hollow structure and an inner suction tube fixed to the front end of the holding handle, a trigger is hinged to the holding handle, a loop tube is fixed to the front end of the inner suction tube, a loop placing groove is formed in the loop tube, a sliding groove is formed in the loop tube, an outer tube is connected to the inner suction tube in a sliding and sleeved mode, a push tube is fixed to the front end of the outer tube, a push block is arranged at the front end of the push tube and embedded in the sliding groove, and a movable tube is connected to the rear end of the outer tube. Four ferrule placing grooves are formed in the snare tube, four rubber rings can be placed at a time, a rotary knob is rotated during use, themovable tube moves backwards under the action of the spring, then the initial position of the push block on the snare tube and the displacement stroke of the push block on the snare tube can be controlled, and then the percussion number is controlled; single shot and continuous shot can be achieved, and continuous work can be achieved.

Description

technical field [0001] The invention relates to the field of medical appliances, in particular to an anorectal ligation stapler with precise and controllable stroke. Background technique [0002] Hemorrhoids are one of the most common anorectal diseases in life, and can occur at any age. Although it will not seriously endanger the health of the body, it will cause great inconvenience to the life of the patient. The conventional way of existing treatment hemorrhoid is ligation and anastomosis therapy. Ligation and anastomosis therapy requires the use of a ligation device. During the operation, the automatic ligation device is aimed at the hemorrhoids, and the hemorrhoids are sucked into the head of the ligation device by negative pressure suction. At the base of the hemorrhoids, a rubber ring is ligated to cut off the blood supply of the hemorrhoids. The hemorrhoids are naturally detached and necrotic, the whole process does not require surgery, and the wound is small. This...

Problems solved by technology

[0003] The existing binding device includes a push tube and an adsorption tube. The apron is set on the adsorption head, and the apron is separated from the absorption tube by controlling the push tube. It can perform one ligation work. When the patient has multiple hemorrhoids in the anus and needs to be ligated at the same time, it is necessary to repeatedly take out the ligation device and replace it with a new one to complete the above work, which is very troublesome and seriously affects the user experience
