The modus operandi that minimally invasive excision is carried out to early carcinoma of stomach that person initiates, various electric knifes and ancillary equipment cooperate scope guidance will together
Gastral pathological tissues are removed.Traditional ESD method is using IT knife and snare etc., and process is easy but there are lesion mucous membranes
It remains, remove the hidden danger such as too deep, bleeding and perforation risk also increase.Domestic and international correlative study is thought to operate by " both hands " advantageous
In rapid complete resection lesion, operating time is reduced, the road Ji Yiqian is removed using IT knife, and a pincers road utilizes foreign body forceps or circle
Set device gently mentions lesion or perienchyma, exposes the surface of a wound sufficiently.But it is costly using binary channels scope, and binary channels scope
Since the larger insertion process of sectional area is also more difficult, institute is not yet universal in clinic in this way.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of digestive endoscopy with pipe sleeve, pipe sleeve can be unfolded
Auxiliary casing is formed afterwards, by assisting casing that can carry out " both hands " operation when operation.
In order to solve the above technical problems, the utility model provides a kind of digestive endoscopy, including a cross sectional shape is circle
The single-chamber digestive endoscopy ontology of shape, it is arc-shaped pipe that the digestive endoscopy ontology outer circumferential, which is equipped with a cross sectional shape,
Set, pipe sleeve length direction two sides are corresponding with digestive endoscopy body length direction two sides concordant；
If arc-shaped pipe sleeve be radially close to the side of digestive endoscopy ontology it is interior, far from digestion internal diameter ontology side be
Outside, the pipe sleeve includes the inside and outside internal layer body and outer layer body folded against, and the internal layer body, outer layer body are elasticity
Material is made, and the internal layer body is corresponding along two sides of circular arc circumferential direction with outer layer body along two sides of circular arc circumferential direction
Connection；
A fixed ring is equipped on the medial surface position of the internal layer body at the front end of digestive endoscopy ontology, Gu
Determine ring and digestive endoscopy body fits are socketed on digestive endoscopy body portion；
One is equipped on the lateral surface position of the outer layer body at the front end of digestive endoscopy ontology along outer layer jacket
Body circular arc circumferentially, arc-shaped gas tube made of flexible material, be equipped with connection gas tube both ends between gas tube both ends
Connecting tube, gas tube, connecting tube constitute the tube body of a circumferential closure, and connecting tube is identical as gas tube material and connecting tube pipe
Wall thickness is less than gas tube pipe thickness, and gas tube is equipped with a strip air injection pipe being connected to gas tube, gas injection pipe range
It is concordant on rear side of digestive endoscopy ontology to spend side of the direction far from gas tube.
For the sake of simple declaration problem, a kind of digestive endoscopy described in the utility model is referred to as in this digestion below
Mirror.
The application method of this digestive endoscopy are as follows: by the target position of this digestive endoscopy head insertion human body, then pass through note
Tracheae is inflated into gas tube, connecting tube, and with pressure increase, connecting tube is broken internal layer body from the junction with outer layer body
Pop-up, arc-shaped pipe sleeve become a cylindrical auxiliary casing, by assisting casing that can stretch foreign body forceps or snare
Enter human body, carries out " both hands " operation.
The advantages of this digestive endoscopy: this digestive endoscopy is equipped with a pipe sleeve, and pipe sleeve forms auxiliary casing, leads to after being unfolded
Foreign body forceps or snare can be protruded into human body by crossing auxiliary casing, carried out " both hands " operation, be conducive to rapid complete resection lesion,
Operating time is reduced, casing is assisted to protrude into human body with digestive endoscopy ontology in the form that folds, insertion is convenient, additionally, due to originally disappearing
Changing scope is using the more cheap single-chamber digestive endoscopy of price in conjunction with auxiliary casing, and overall cost is cheap, can effectively draw
Low operation cost.
To reach the better using effect of this digestive endoscopy, preferred embodiment is as follows:
Preferably, the connection pipe diameter is less than the diameter of gas tube.
Pipe diameter is small is more easily broken off for connection.
Detailed description of the invention
Fig. 1 is the structural schematic diagram (before pipe sleeve expansion) of this digestive endoscopy.
Fig. 2 is the portion the A partial enlarged view of Fig. 1.
Fig. 3 is another structural schematic diagram of this digestive endoscopy (after pipe sleeve expansion).
Specific embodiment
Referring to figures 1-3, a kind of digestive endoscopy, including a cross sectional shape are circular single-chamber digestive endoscopy ontology 1, institute
It is arc-shaped pipe sleeve 2 that 1 outer circumferential of digestive endoscopy ontology stated, which is equipped with cross sectional shape, 2 length direction two sides of pipe sleeve with
1 length direction two sides of digestive endoscopy ontology are corresponding concordant；
If arc-shaped pipe sleeve 2 is radially interior, the side far from digestion internal diameter ontology close to the side of digestive endoscopy ontology 1
To be outer, the pipe sleeve 2 includes the inside and outside internal layer body 21 and outer layer body 22 folded against, the internal layer body 21, outer layer jacket
Body 22 is that elastic material is made, and the internal layer body 21 is along two sides of circular arc circumferential direction and outer layer body 22 along circular arc week
To two sides be correspondingly connected with；
A fixed ring is equipped on the medial surface position of the internal layer body 21 at the front end of digestive endoscopy ontology 1
4, fixed ring 4 and the cooperation of digestive endoscopy ontology 1 are socketed on 1 front of digestive endoscopy ontology；
