The diameter of nerve is identical, i.e., contacts but do not oppress with sciatic nerve outer wall, this is high to the suturing skill level requirement of doctor, behaviour
It is big to make difficulty, and cannot reuse, it is at high cost.
Utility model content
In order to solve the above-mentioned technical problem, the purpose of this utility model is to provide a kind of adjustable sciatic nerve sets of internal diameter
Pipe, it is simple and efficient to handle, it is low to Doctors' skill requirement, and can Reusability.
To achieve the goals above, the technical solution of the utility model is: a kind of sciatic nerve casing, including a casing
Ontology, described sleeve pipe ontology both ends open, co-axial seal connects a circular membrane on inner wall, described circular membrane one end extend to
Described sleeve pipe ontology corresponding end flushes, and the inner wall of the circular membrane and described sleeve pipe ontology corresponding region is enclosed membrane vesicle chamber,
The membrane vesicle chamber is equipped with and its internal interface being connected to, the interface connection air charging system, to be filled with gas to membrane vesicle is intracavitary
Body makes its expansion.The beneficial effect of above-mentioned technical proposal is that setting circular membrane and sleeve body inner wall are enclosed membrane vesicle chamber,
It, can be by depth by squeezing the expansion of membrane vesicle chamber inwardly so that the internal diameter of corresponding region reduces to the intracavitary injection gas of membrane vesicle
Enter in it outer wall contact of sciatic nerve but do not oppress, operates extremely convenient and quick.
Interface described in above-mentioned technical proposal is set in described sleeve pipe ontology, and the orifice has pipeline, described
It is external that the one end of pipeline far from interface by the described sleeve pipe ontology other end extends to described sleeve pipe sheet.
The beneficial effect of above-mentioned technical proposal is, interface is arranged in sleeve body and extends casing by pipeline
Ontology is avoided that influence of the pipeline to operation, so that the structure of device is more reasonable.
Sleeve body body described in above-mentioned technical proposal is made of lightweight plastic material.
The beneficial effect of above-mentioned technical proposal is, reduces compressing of the gravity to sciatic nerve of sleeve body.
Circular membrane described in above-mentioned technical proposal is made of latex or silica gel material.
The beneficial effect of above-mentioned technical proposal is that hygienic nontoxic and dilatancy is good.
Interface described in above-mentioned technical proposal is set to what the circular membrane other end was connect with described sleeve pipe inner body wall
Position.
The beneficial effect of above-mentioned technical proposal is, adapts to the needs of the sciatic nerve operation of different lengths.
Air charging system described in above-mentioned technical proposal is syringe.
The beneficial effect of above-mentioned technical proposal is, easy to operate, convenient for control, i.e., inflatable to be evacuated, can be in time
The dilation of membrane vesicle chamber is adjusted.
Detailed description of the invention
Fig. 1 is the structure diagram of sciatic nerve casing described in the utility model embodiment.
In figure: 1 sleeve body, 2 circular membranes, 21 interfaces, 22 pipelines, 3 air charging systems, 4 sciatic nerves.
Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
As shown in Figure 1, a kind of sciatic nerve casing is present embodiments provided, including a sleeve body 1, described sleeve pipe sheet
1 both ends open of body, co-axial seal connects a circular membrane 2 on inner wall, and described 2 one end of circular membrane extends to and described sleeve pipe ontology
1 corresponding end flushes, and the circular membrane 2 and the inner wall of 1 corresponding region of described sleeve pipe ontology are enclosed membrane vesicle chamber, the membrane vesicle chamber
It is equipped with and its internal interface 21 being connected to, the connection of interface 21 air charging system 3, to make it to the intracavitary gas that is filled with of membrane vesicle
Expansion.The sciatic nerve 4 is extend into described sleeve pipe ontology 1 from membrane vesicle chamber one end concordant with described sleeve pipe ontology 1, wherein
The internal diameter of sleeve body can control 5mm, and length can be controlled in 1-2cm, and the length of membrane vesicle chamber can be controlled in 1-1.5cm.Pass through
Air charging system is inflated so that membrane vesicle chamber is inwardly expanded to contacts with the periphery of the sciatic nerve.
Interface 21 described in above-described embodiment is set in described sleeve pipe ontology 1, and the interface 21 is communicated with pipeline 22,
The described one end of pipeline 22 far from interface 21 is extended to outside described sleeve pipe ontology 1 by 1 other end of described sleeve pipe ontology.
The body of sleeve body 1 described in above-described embodiment is made of lightweight plastic material, does not require sleeve body herein certainly
Hardness, can be bent, can be made of rubber or silica gel or latex.
Circular membrane 2 described in above-described embodiment is made of latex or silica gel material.
Interface 21 described in above-described embodiment is set to 2 other end of circular membrane and connect with 1 inner wall of described sleeve pipe ontology
Position.
Air charging system 3 described in above-described embodiment is syringe, and wherein syringe preferably uses small syringe, such as maximum to hold
Amount is that the syringe of 1mL or 2mL is practical.
Specifically, the wall thickness at the both ends of the circular membrane is relatively thin, the wall thickness of central region is big, gas is being filled with to membrane vesicle is intracavitary
After body, circular membrane central region not will form arcuate structure more outstanding, relatively flat instead, so that circular membrane and ischium
The contact area of neural outer wall increases.
Specifically, transparence can be made in described sleeve pipe ontology and circular membrane, it is accurate clear during operation convenient for medical staff
The sciatic nerve of Chu observed in sleeve body.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
