Abstract

The utility model discloses an airway stent implantation device. The airway stent implantation device comprises inner sheath pipes, outer sheath pipes, inner core pipes and supports, wherein scales are marked on the inner sheath pipes. The airway stent implantation device is convenient to operate, has the advantages of being accurate, stable, efficient and the like, has good practicability, and can generate good economical benefits and social effects.

Description

A kind of airway stent placement device

Technical field

This utility model belongs to technical field of medical instruments, and what relate to is airway stent placement device, especially a kind of disposable airway stent placement device.

Background technology

At present, during existing airway stent placement device work, first along bronchoscopic work duct, guiding steel wire is imported to pathological changes segmental bronchus intracavity, withdraw from fibre bronchus mirror; Then reinsert bronchoscope to diseased region upper end; Then under fibre bronchus mirror's direct-view, along seal wire, pusher is delivered to narrow positions; Finally, after support discharges completely and fully expands, withdraw from pusher.Obviously, the shortcoming that the direct-view of this dependence Inner mirror obviously has comprises: 1) because Inner mirror and inserter need to enter tract simultaneously, thus at least to be equipped with a ultra-fine Inner mirror, and the equal ultra-fine Inner mirror of not conventional configuration of general hospital; 2) need operated by two people just can complete, a people holds bronchoscope, and another people holds support inserting device.Even if do not rely on the direct-view of Inner mirror, adopt perspective (or DSA) guiding, can not overcome following shortcoming: 1), even if operator and patient properly protect, still can accept the irradiation of X ray, affect medical personnel healthy; 2) need specialized operations chamber, cannot complete by bedside; 3) DSA is comparatively expensive, and part different medical unit does not configure.Certainly, the operation that also has some not rely on perspective or Inner mirror, i.e. " blind putting ", and adopt operation in this way, and sheath pipe in the process need of support release is fixed, retreats epitheca pipe, and simple " blind putting " extremely difficulty accurately places support.

Utility model content

Goal of the invention: for the deficiencies in the prior art, the purpose of this utility model is to provide a kind of airway stent placement device, makes it have the features such as accurate stable, easy to operate, high efficiency, meets user demand.

Technical scheme: in order to realize foregoing invention object, the technical solution adopted in the utility model is as follows:

An airway stent placement device, comprises interior sheath pipe, epitheca pipe, inner core tube and support; On described interior sheath pipe, be marked with graduation mark.

Described inner core tube is can be by the inner core tube of guiding steel wire.

Described epitheca pipe is transparent epitheca pipe.

The diameter of described epitheca pipe is 4mm, and length is 600mm.

Described inner core tube is located in interior sheath pipe, and imports end and expose interior sheath pipe, is wrapped in support importing end periphery by epitheca pipe.

Beneficial effect: compared with prior art, this utility model airway stent placement device, easy to operate, have accurately, the feature such as stable, high efficiency, there is good practicality, can produce good economic benefit and social effect.

Accompanying drawing explanation

Fig. 1 is the structural representation of airway stent placement device.

The specific embodiment

Below in conjunction with accompanying drawing, this utility model is described further.

As shown in Figure 1, airway stent placement device mainly comprises the structure members such as interior sheath pipe 1, epitheca pipe 4, guiding steel wire 5, inner core tube 6 and support; Inner core tube 6 is located in interior sheath pipe 1, and imports end and expose interior sheath pipe 1, is wrapped in support importing end periphery by epitheca pipe 4.On interior sheath pipe 1, be marked with graduation mark 2, and preferably, sheath pipe 1 is white, graduation mark 2 is black, and color contrast is obvious.Inner core tube 6 adopts can pass through the inner core tube of guiding steel wire 5.Epitheca pipe 4 is transparent epitheca pipe, and its diameter is 4mm, and length is 600mm.On interior sheath pipe 1, do not establish medicine-pouring hole, make structure simpler, and easily make.

This airway stent placement device is when work, first use any model of bronchoscope 3() measure narrow end to the length of front tooth (or nose, tracheal intubation opening), then by the graduation mark 2 of this length mark sheath pipe 1 in support inserting device, again support inserting device is inserted separately to air flue to the graduation mark of labelling, exit epitheca pipe 4 and discharged support.

This airway stent placement device, easy to operate, have accurately, the feature such as stable, high efficiency, there is good practicality.
