Gastrointestinal endoscope polyp removal auxiliary collector and method

Abstract

The invention discloses a gastrointestinal endoscope polyp removal auxiliary collector and method. The auxiliary collector comprises a storage box, a control screen, pull-back winding machines, steel wire ropes, a gastroscope tube and a removal device, the control screen is installed on a shell at the upper end of the storage box, a polyp storage chamber is arranged in a central shell of the storage box, the gastroscope tube is installed on the shell wall of the left side of the storage box, a removing device is arranged in a tube shell at the left end of the gastroscope tube, a removing assembly, a positioning assembly and a U-shaped conveying tube are arranged in the removing device, pull-back winding machines are installed on the right sides right corresponding to two ports of the right side of the U-shaped conveying tube,double-layer guide rods which are horizontally arranged up and down are installed in the U-shaped conveying tube, the double-layer guide rods are sleeved with a plurality of sets of collecting boxes arranged at equal intervals, the collecting boxes are tightly connected through the steel wire ropes, the two ends of the collecting boxes are connected with reels in the corresponding pull-back winding machines respectively, and a feeding port is formed in the arc-shaped pipe face of the left side of the U-shaped conveying tube.

Description

technical field [0001] The invention relates to the technical field of medical appliance products, in particular to an auxiliary polyp collector and method for gastrointestinal endoscope extirpation. Background technique [0002] Polyps refer to abnormally growing tissues that protrude from the mucosal surface. They are commonly called polyps before the pathological nature is determined. Generally speaking, polyps are formed due to the growth and aggregation of cells originating from the mucosa. The polyps that grow in the stomach are called gastric polyps, which are common clinical diseases. In clinical practice, most gastric polyps are found incidentally during upper gastrointestinal endoscopy. The vast majority of polyps are benign lesions and are not life-threatening, and only some polyps have a tendency to become cancerous and require active treatment. Moreover, samples of excised polyps need to be preserved for testing to determine the pathological nature of the polyps...

Problems solved by technology

Existing excision and collection of polyps, among them, high-frequency electrocoagulation is the most widely used method. In the process of excision of pedicled polyps or narrow-pedicled polyps, the thermal effect generated by high-frequency current is used to promote tissue coagulation and necrosis to achieve The purpose of polypectomy is often to cut the root pedicle by heating and solidifying. Because the polyp is soft and easy to collapse, it is difficult to remove the root pedicle, which will cause the polyp to be in close contact with the electric wire and damage the structure of the polyp, especially for small polyps. The damage is greater, which will affect the subsequent pathological detection data of polyps, and then affect the treatment of patients; and in order to avoid this situation, the patient's body position is usually changed, the operation is cumbersome and inconvenient, and the quality after polypectomy cannot be guaranteed
