An improved tubular digestive tract stapler

Abstract

The invention discloses an improved tubular digestive tract anastomat which comprises a fixing handle, a movable handle, a nail bin, a transition tube and a nail abutting seat. The fixed handle is connected with an injection mechanism through a sleeve body, the injection mechanism comprises an injection cylinder, an injection push rod and an injection tube located at the front end of the injectioncylinder, the injection tube penetrates through the fixed handle and the transition tube to extend to the outside of the nail bin, a liquid outlet of the injection tube faces the side of the injection tube, a rotary cylinder communicated with the injection cylinder is arranged at the top of the injection cylinder, the injection tube is introduced into the rotary cylinder and is fixed to the rotary cylinder, a rotary groove matched with the rotary cylinder is formed in the injection cylinder, and the rotary cylinder is located in the rotary groove in a matched mode. Compared with the prior art, the injection tube injects medicine according to a round medicine spraying trajectory, accordingly liquid medicine can be comprehensively in contact with the lesion part to be sutured, the medicineinjection uniformity is remarkably improved, wound healing is quickened, and a medicine injection effect is ensured.

Description

Technical field [0001] The invention relates to the technical field of medical devices, in particular to an improved tubular digestive tract stapler. Background technique [0002] At present, for digestive tract surgery, a stapler is generally used to remove and suture the diseased tissue. The traditional stapler has a single function and requires additional medication after the operation, which prolongs the operation time and increases the patient's pain. [0003] The patent number is 201420196135.5, which discloses an injection structure that can be used to administer drugs to the diseased area during and after the operation. However, this injection structure can administer drugs to the diseased area through an injection tube. During the administration, the injection direction of the liquid medicine in the injection tube cannot be controlled, so that the administration of the diseased part is very uneven, and the administration effect is not good. Summary of the invention [0004...

AI Technical Summary

Problems solved by technology

[0002] At present, for digestive tract surgery, the lesion tissue is usually resected and sutured with a stapler. The traditional stapler has a single function, and additional medication is required after the operation, which prolongs the operation time and increases the pain of the patient.

[0003] The patent number is 201420196135.5, which discloses an injection structure that can administer medicine to the lesion through the injection mechanism during and after the operation, but this injection structure administers medicine to the lesion through the injection tube. When administering medicine, it is impossible to control the injection direction of the medicinal liquid in the injection tube, which makes the administration of the diseased part very uneven and the effect of administration is not good.
