Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a grasping device for stone surgery. Background Art

[0002] Endoscopic stone extraction basket is a tool used in endoscopic examination and treatment to remove stones or other foreign bodies in the body. It is usually made of special materials (such as stainless steel) with a fine mesh structure and appropriate elasticity. The main function of the endoscopic stone extraction basket is to insert it into the body cavity under the guidance of an endoscope and perform stone extraction or foreign body extraction by taking stones. The endoscope enters the body through the natural orifices of the human body or through minimally invasive surgery, and can observe and operate organs and tissues inside the human body. The use of an endoscopic stone extraction basket can reduce the harm of surgical incisions to patients, while improving the accuracy and safety of the operation. When using an endoscopic stone extraction basket, the doctor usually guides it into the body cavity, opens the basket to capture stones or foreign bodies, and then gently pulls it out to complete the process of stone extraction or foreign body extraction. The structure of the basket can prevent stones or foreign bodies from slipping and trap them in the basket to avoid further movement and damage. When the endoscopic stone removal basket is used, the handle may slip when grasping, causing the grasping device to fall out of the hand. Utility Model Content
