Description

Auxiliary device for endoscope treatment

Technical Field

The invention relates to the field of medical equipment, in particular to an endoscopic treatment auxiliary device.

Background

With the development of minimally invasive endoscopic techniques, some digestive tract lesions, such as early stage digestive tract tumors, can be resected safely and effectively under an endoscope. Compared with the surgical operation, the endoscope minimally invasive technique is small in wound, simple and quick, however, certain limitations exist. Endoscopes belong to the soft endoscope and the single Kong Daona scope, and the operation of the endoscopist is similar to a single arm operation. This is not comparable to the flexibility and maneuverability of surgical and laparoscopic procedures under multi-tunnel, double arm procedures. Current soft endoscopes can only pass through one endoscope accessory.

To solve this limitation, a floss assist method, a weight-clip assist method, a bending clamp assist method, and a double clamp assist ESD method have been studied. These methods are mainly applied to pull the mucosa in Endoscopic Submucosal Dissection (ESD) to aid in endoscopic treatment. These methods are similar to the action of the second hand, leaving the wound exposed by pulling on the lesion to aid in the treatment of ESD. However, these methods are not very flexible in operation. At a specific lesion, such as a lesion of the fundus of the stomach, the front end of the endoscope is in a curved state, which causes a difficulty in the operation of these auxiliary forceps; these methods do not allow for simple, rapid, arbitrary adjustment of the position of the jaw lesion; in addition, these methods can only be used for adjuvant therapy of ESD surgery, and the application range is limited. Therefore, there is a need for an endoscopic treatment aid that ameliorates the foregoing shortcomings.
