Description

Technical Field

[0001] The utility model relates to the field of ligation staplers, in particular to an automatic hemorrhoid ligation stapler. Background Art

[0002] Hemorrhoid stapler is a medical device that treats internal hemorrhoids by circularly cutting and anastomosing the mucosa above the hemorrhoids. Hemorrhoids are mainly caused by the downward displacement of anal cushions and varicose veins. The use of staplers can circumcise a part of the rectal mucosa and close its ends, thereby reducing or eliminating the internal hemorrhoids. Hemorrhoid patients may experience symptoms such as anal pain, itching, and bleeding. After using the stapler, these discomforts may be alleviated or disappear. In order to confirm hemorrhoids, doctors usually recommend routine examinations such as digital rectal examination and anoscopy. If necessary, ultrasound examinations may be arranged to evaluate the size and location of hemorrhoids. Hemorrhoid stapler surgery is a type of minimally invasive surgery suitable for the treatment of internal hemorrhoids. After surgery, drugs need to be replaced regularly, such as Mayinglong Musk Hemorrhoid Cream, Erythromycin Ointment, etc., to prevent the occurrence of infection. A Chinese patent discloses an automatic elastic line hemorrhoid ligation stapler (authorization announcement number CN 210871827 U), this patented technology can be used for the automatic elastic line hemorrhoid ligation stapler. Through the setting of the placement frame, when it is not needed, the stapler is placed inside the placement frame through the gun handle. The magnetic block inside it can play a certain fixing role on it. Then the two fixing plates are pushed to the side close to the gun handle. After completion, the limit rod bounces upward under the force of the extrusion spring, fixes the state of the fixing plate at this time, and prevents the gun handle from easily detaching from the placement frame, thereby achieving the purpose of convenient storage and use. However, the gun head and elastic line structure of this design are single, and cannot form effective sutures under special tissue thickness. The gun head is not provided with a grasping structure, and cannot provide a good suture grasping mechanism. Therefore, those skilled in the art provide an automatic hemorrhoid ligation stapler to solve the problems raised in the above background technology. Utility Model Content
