Magnetic assisted tensioning device for digestive endoscopy surgery

Abstract

The invention discloses a magnetic assisted tensioning device for digestive endoscopy surgery, which comprises an in-vitro electromagnet and also comprises an in-vivo branch matched with the in-vitro electromagnet, wherein the in-vivo branch is composed of an in-vivo magnet and micro-surgical forceps which are connected through connecting lines. The tensioning of the focus is completed by utilizing magnetic attraction to achieve the purpose of surgical field exposure. The magnetic assisted tensioning device is especially suitable for lower excision of the gastric mucosa through the digestive endoscopy. By using the device, a tensioning instrument can be used without occupying the operation channel of the digestive endoscopy, the surgical field exposure is still sufficient when the focus is excised, and the focus with the diameter greater than 20mm of the body of the stomach and duodenum can be possibly excised through the digestive endoscopy, thereby expanding the indications of the endoscopy surgery, meeting the requirements of more patients for minimally invasive surgery, and avoiding the wound to a patient due to the laparotomy.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a magnetic auxiliary pulling device for digestive endoscopic surgery. Background technique [0002] Minimally invasive surgical technology is an important trend in the development of today's surgical field, and its principle is to achieve the purpose of surgical treatment with a minimally invasive method. Digestive endoscopy is an important part of modern minimally invasive technology, and it plays an increasingly important role in the diagnosis and treatment of gastrointestinal diseases. Gastrointestinal tumors have been widely recognized by the society, among which the most prominent one is endoscopic gastric submucosal resection for the treatment of superficial gastric cancer. Compared with traditional surgery, this method has incomparable advantages in terms of less trauma, faster recovery of patients and meeting the cosmetic requirements of patients. At...

AI Technical Summary

Problems solved by technology

[0003] However, the defects of existing digestive endoscopes limit the further popularization and application of digestive endoscopic submucosal gastrectomy.

At present, when performing digestive endoscopic submucosal gastrectomy, various devices needed to complete the operation must enter the stomach through the operation channel, and the space of the operation channel is limited, which cannot meet the simultaneous operation of multiple surgical instruments

Therefore, in actual operation, traction instruments cannot be used when performing gastric submucosal resection. As a result, when the lesion is located in the gastric body or the lesion area is too large, generally referring to its diameter greater than 20mm, due to the exposure of the surgical field , the operation cannot be performed
