Description

An instrument for locating tumors through gastroscope forceps

technical field

The invention belongs to the technical field of medical instruments, and in particular relates to an instrument for locating tumor positions through gastroscope forceps.

Background technique

Gastrointestinal tumors are diseases involving abnormal growth of cells that occur in the gastrointestinal tract and organs related to digestive function, such as the esophagus, stomach, biliary system, pancreas, small intestine, large intestine, rectum, and anus, gastrointestinal tumors Symptoms vary depending on the organ or tissue affected. For example, symptoms associated with esophageal tumors include dysphagia, chest pain, cough, and hoarseness; while symptoms associated with stomach tumors include vomiting, nausea, abdominal pain, and blood in the stool.

For the current gastrointestinal tumors, when the tumor is treated by laparoscopic surgery, because the tumor is mostly in the mucosal layer of the gastrointestinal tract, it is impossible to effectively find the tumor through the abdominal cavity and perform real-time surgery. Therefore, it is necessary to locate the tumor before the operation. Mostly, the location of the tumor is found under the preoperative gastroscope, and the titanium clip is used for positioning. The specific method is to clamp the titanium clip on the mucosa of the gastrointestinal tract, and then find the titanium clip to reduce the risk of finding the tumor during laparoscopic surgery. difficulty. However, because the current fixation method of titanium clips is in the cavity, it is still difficult to find the tumor location in the abdominal cavity. Moreover, the titanium clip is prone to loosening and position changes during the clamping process.
