Simple auxiliary tube device for endoscopic treatment

Abstract

The invention discloses a simple auxiliary tube device for endoscopic treatment. The simple auxiliary tube device for endoscopic treatment comprises a short hard tube, a ductile main tube, an elongated hard tube and traction strings, wherein the short hard tube is fixed on a lateral endoscope body in the bent direction of the front end of an endoscope body, and the front end of the short hard tube is flush with the front end of the endoscope body; the main tube is fixed on the lateral endoscope body in the bent direction of the front end of the endoscope body, is positioned on the same side as the short hard tube and clings to the short hard tube, the front end of the main tube is flush with the front end of the endoscope body, and a tube section in the front of the main tube is detachably arranged on the endoscope body; the elongated hard tube is fixed to the endoscope body closely to the main tube and is arranged on the side as the short hard tube; one end of one traction string is tied to the head end of an auxiliary treatment accessory while the other end thereof is positioned outside the endoscope body; one end of each of the other two traction strings is tied to the head end of the main tube and passes through holes of the short hard tube and two independent holes of the elongated hard tube. The simple auxiliary tube device for endoscopic treatment is capable of achieving 'two-arm' operation and aiding endoscopic treatment flexibly and rapidly.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a simple endoscopic treatment auxiliary pipeline device. Background technique [0002] With the development of minimally invasive endoscopic techniques, some gastrointestinal lesions, such as early-stage gastrointestinal tumors, can be safely and effectively removed endoscopically. Compared with surgical operations, endoscopic minimally invasive techniques are less invasive, simpler and faster, however, there are certain limitations. Endoscopes belong to flexible endoscopes and single-port endoscopes, and the operation of the endoscopist is similar to the single-arm operation. This is not comparable to the flexibility and maneuverability of surgery and laparoscopic surgery under the multi-channel dual-arm operation. [0003] To address this limitation, floss-assisted method, hammer-clamp-assisted method, curved forceps-assisted method, and double-clamp-assisted ESD have been stud...

AI Technical Summary

Problems solved by technology

However, these methods are not very flexible in operation

In special lesions, such as when resecting the lesions of the gastric fundus, the front end of the endoscope is in a curved state, which makes it difficult to operate these auxiliary forceps; these methods cannot simply and quickly adjust the position of the clamped lesions arbitrarily; The method can only be used as an adjuvant therapy for ESD, and the scope of application is relatively limited
