Integral sleeve type endoscopic therapy auxiliary pipeline device

Abstract

The invention discloses an integral sleeve type endoscopic therapy auxiliary pipeline device, which comprises a sleeve, a transparent cap, a main pipe and a traction rope, wherein the inside structure of the sleeve comprises a C-shaped metal clamp ring, a main hole passage, a fine hole passage and a metal card; the C-shaped metal clamp ring fixes the sleeve onto an endoscope body; a therapy auxiliary component passes through the main hole passage; the traction rope passes through the fine hole passage; the metal card is embedded in the fixing traction rope of the surface of the sleeve; a fixing pile is arranged at one side of the surface of the transparent cap, and is used for assisting the traction rope to drag the main pipe and to fix the front end of the main pipe; the main pipe and the fixing pile are positioned at the same side surface of the front end of the endoscope body; the main pipe is a short pipe; the back end of the main pipe is externally connected with the main hole passage inside the sleeve; other parts of the main pipe do not need to be fixed on the endoscope body, and are used for penetrating the therapy auxiliary components; the other end of the traction rope tied at the front end of the main pipe is the operation end, near the endoscope body, of the traction main pipe penetrating through the fine hole passages inside the sleeve and the fixing pile. The integral sleeve type endoscopic therapy auxiliary pipeline device provided by the invention has the advantages that the two-arm operation can be realized; the treatment under the endoscope can be flexibly and fast assisted.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an integrated sleeve-type endoscopic treatment auxiliary pipeline device. Background technique [0002] With the development of endoscopic minimally invasive techniques, some gastrointestinal lesions, such as early gastrointestinal tumors, can be safely and effectively resected endoscopically. Compared with surgery, endoscopic minimally invasive techniques are less invasive, simple and quick, however, there are certain limitations. Endoscopes belong to flexible endoscopes and single-channel endoscopes, and the operation of endoscopists is similar to single-arm operation. This is not comparable to the flexibility and maneuverability of surgery and laparoscopic surgery under the multi-channel double arm operation. Current flexible endoscopes can only pass through one endoscope accessory. [0003] To address this limitation, floss-assisted methods, weight-clip-assisted methods, ben...

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
