Traction fiber gathering assembly, corresponding minimally invasive instrument conveying device and gathering method

Abstract

The invention relates to a traction fiber gathering assembly, a corresponding minimally invasive instrument conveying device and a gathering method, wherein the traction fiber gathering assembly comprises at least two traction fiber channels; at least part of the outer edges of the adjacent traction fiber channels are mutually cemented; the minimally invasive instrument conveying device consists of a bending part, an insertion part, an operation handle, a traction fiber, an inner catheter and the traction fiber gathering assembly. According to the traction fiber gathering assembly with the structure, the external size of the insertion part of an endoscope is reduced through mutually cementing the traction fiber channels, and the corresponding minimally invasive instrument conveying device of which the working ducts are independent is a special conveyer, so that double-working duct surgery can be realized, and the minimally invasive instrument conveying device can be used simultaneously with the traditional endoscopes at present, so that the minimally invasive surgery range of the products at present is enlarged beneficially, the use for minimally invasive surgeries for patients with different physical signs can be fully satisfied and the surgery efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of endoscopes, in particular to a minimally invasive surgical instrument delivery device, in particular to a pulling wire gathering assembly, a corresponding minimally invasive instrument delivery device and a gathering method. Background technique [0002] At present, the traditional endoscope is generally a product designed by image sensor, working channel, etc., mainly including tip part, objective lens and image sensor, bending part, insertion part, built-in water supply / air supply, and forceps tube channel of delivery equipment, etc. The biggest disadvantage of the concept of traditional integrated design of endoscope is that the endoscope has only one working channel, and the working channel is built into the insertion tube of the endoscope as a whole, which is affected by the outer diameter of the integrated product and other devices. Due to the limited arrangement of the insertion tube and the design...

Problems solved by technology

[0002] At present, the traditional endoscope is generally a product designed by image sensor, working channel, etc., mainly including tip part, objective lens and image sensor, bending part, insertion part, built-in water supply / air supply, and forceps tube channel of delivery equipment, etc. The biggest disadvantage of the concept of traditional integrated design of endoscope is that the endoscope has only one working channel, and the working channel is built into the insertion tube of the endoscope as a whole, which is affected by the outer diameter of the integrated product and other devices. Due to the limited arrangement of the insertion tube and the design of the built-in single hole, it is impossible to use double minimally invasive instruments to treat the lesion. At the same time, it has other multiple functions such as water delivery and image transmission, and cannot use the bending part delivery device alone
