Problems solved by technology

For drug delivery or biopsy forceps), but in the treatment of large lesions, especially ESD treatment, bleeding and other conditions are often prone to occur, requiring the coordination of multiple devices (such as coagulation) or auxiliary devices (such as suction and irrigation tubes) Function, if it is necessary to repeatedly replace the treatment device (in the lumen of the endoscope) during treatment, it will increase the difficulty of the operation and prolong the operation time
Existing endoscopes cannot further increase the diameter of the tube

Embodiment 1

[0019] Such as figure 1 As shown, an auxiliary channel film cover for endoscopic treatment, including a transparent cap 1 and a film cover 2 with an annular hollow structure; the transparent cap wall is fixed to the ends of the film cover 2, and both ends of the film cover are open; The diameter of the transparent cap 1 is 10 mm, which can be hooped on the head of the endoscope, and the membrane channel tube 2 is driven into the body through the endoscope.

[0020] Preferably, the film cover 2 selected in this embodiment is composed of two layers of films bonded together, and the two layers of films are divided into three strips of the same width at equal distances along the width direction, and each dividing line is closely bonded to form three parallel channels , the outside of any end of the film is closely bonded to the wall of the transparent cap 1 . The film is covered with the channel outlet at the port of the endoscope, and the treatment equipment can be directly exte...

Embodiment 2

[0025] An auxiliary channel film cover for endoscopic treatment, comprising a transparent cap 1 and a film cover 2 with an annular hollow structure; Long strips with the same length and the same width, each parting line is tightly bonded to form several parallel channels, in which one end of the A-layer film protrudes from the B-layer film by 2-5mm, and faces the side of the B-layer film and the outer wall of the transparent cap 1 Tight bonding; the diameter of the transparent cap 1 is 10±1 mm, which can be hooped on the head of the endoscope, and the film channel tube 2 is driven into the body through the endoscope. Wherein, the parallel channel can be set to be 1 meter to 3 meters long, and 1 to 4 channels can be set as required.

[0026] The endoscopic part described in this embodiment refers to the frontmost part of one end of various endoscopes extending into the body cavity. Because there are various diameters of the endoscope, various transparent caps matching it can b...

Abstract

The invention provides an auxiliary channel film sleeve for use in endoscopical therapy. The auxiliary channel film sleeve comprises a transparent cap and a film sleeve, wherein the transparent cap has an annular hollow structure; a transparent cap wall is fixed to the end part of the film sleeve; the two ends of the film sleeve are opened; the diameter of the transparent cap is adaptive to the diameter of an endoscope; the transparent cap can be hooped on the head of the endoscope, and is used for driving the film sleeve to enter a human body through the endoscope. The diameter of the endoscope varies, so that a plurality of transparent caps matched with the endoscope can be manufactured and hooped on the head of the endoscope. The film sleeve for use in combination with endoscopes such as colonoscopies, gastroscopes and colposcopes can be sleeved at the head end of the endoscope and brought into the human body. During therapy, a suction apparatus, a flushing tube, a pair of hot biopsy forceps and the like can be inserted through the auxiliary channel film sleeve, so that convenience is brought to treatment, the treatment process is simplified, the surgery efficiency is increased, and the therapy safety is enhanced.

Description

technical field [0001] The invention relates to an auxiliary channel film sleeve for endoscopic treatment. Background technique [0002] During endoscopic treatment, due to the limitation of the endoscopic treatment channel, only 1-2 treatment devices can be inserted (commonly only 1-2 lumens are used. For drug delivery or biopsy forceps), but in the treatment of large lesions , Especially when performing ESD treatment, bleeding and other conditions are often prone to occur, which requires the synergy of multiple devices (such as coagulation) or auxiliary devices (such as suction and irrigation tubes). If the treatment device needs to be replaced repeatedly during treatment (endoscopic Intraluminal), it increases the difficulty of the operation and prolongs the operation time. Existing endoscopes cannot further increase the diameter of the tube. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention proposes an auxiliar...
