Description

A kind of reversed balloon sheath

Technical field

The utility model is related to medical instrument, specifically a kind of reversed balloon sheath.

Background technology

Vagina vasorum is directed toward proximal part or distal end when clinically carrying out blood vessel intervention diagnosis and treatment, but for double lower limb When artery needs row both sides vascular interventional treatment, common method is：1. arranged on left and right sides is performed the operation in two times；2. first doing a side left side (or right), then seals the blood vessel for first doing side, then puncture the vascellum laterale and do another vascellum laterale with blood vessel blocking device.This two kinds of sides Method will secondary puncture blood vessel stop blooding twice, this expense that may increase vascular puncture complication, increase additional instrument also increases Add the pain of patient.

Utility model content

It is mentioned above in the background art to solve the purpose of this utility model is to provide a kind of reversed balloon sheath Problem.

To achieve the above object, the utility model provides the following technical solutions：

A kind of reversed balloon sheath, including sacculus, reversed sacculus guide tube body, guide wire exit openings, silk guide passage, gas circuit Channel, seal wire import, air inlet, extension tube, outer sheath and expander, the reversed sacculus guide tube body is by integrally formed Silk guide passage and gas channels are constituted, and silk guide passage and gas channels are mutual indepedent, wherein the outlet side connected ball of gas channels Capsule, and the guide wire exit openings of silk guide passage are opened on the tube wall at sacculus, can be inserted or exit expansion in the outer sheath Prop, the reversed sacculus guide tube body are inserted in outer sheath.

As further program of the utility model：The seal wire imports of the silk guide passage and gas channels and air inlet at Y shape is distributed.

As further program of the utility model：The uropore side of the outer sheath connects the portions such as threeway by extension tube Part.

Compared with prior art, the utility model has the beneficial effects that：

This practicality is by being arranged reversed sacculus guide tube body so that and blood vessel intervention operation only needs one-time puncture blood vessel, Both sides vascular interventional treatment can be once done simultaneously, and playing reduces operating difficulty, the expense of the additional instrument of reduction, also reduces patient's Pain, the effect for improving success rate of operation.

Description of the drawings

Fig. 1 is the Structure explosion diagram of the utility model；

Fig. 2 is the diagrammatic cross-section of reversed sacculus guide tube body.

In figure：Sacculus 1, reversed sacculus guide tube body 2, guide wire exit openings 3, silk guide passage 4, gas channels 5, seal wire import 6, air inlet 7, extension tube 8, outer sheath 9, expander 10.

Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work The every other embodiment obtained, shall fall within the protection scope of the present invention.

Please refer to Fig.1-2, in the utility model embodiment, a kind of reversed balloon sheath, including sacculus 1, reversed sacculus Guide tube body 2, guide wire exit openings 3, silk guide passage 4, gas channels 5, seal wire import 6, air inlet 7, extension tube 8,9 and of outer sheath Expander 10, the reversed sacculus guide tube body 2 are made of integrally formed silk guide passage 4, gas channels 5 and sacculus 1, Silk guide passage 4 and gas channels 5 are mutual indepedent, and wherein the outlet side of gas channels 5 connects sacculus 1, in order to inflate so that ball Capsule 1 blocks blood vessel, and the guide wire exit openings 3 of silk guide passage 4 are opened on the tube wall at sacculus 1, in order to which seal wire is from seal wire It exports and is reached at 3 in the blood vessel cavity that fitting blood vessel wall surface is formed when sacculus 1 is inflated；

The seal wire import 6 of the silk guide passage 4 and gas channels 5 and air inlet 7 are distributed at Y shape, to not interfere seal wire Into the connection with loading line, it might as well also hinder surgical procedure.

The reversed sacculus guide tube body 2 is inserted in outer sheath 9, and the uropore side of outer sheath 9 is connected by extension tube 8 The components such as threeway are connect, in order to which arterial pressure detects.

It also can be inserted into expander in the outer sheath 9.

The work step of the utility model is as follows：

The first step：Right (or left) the side femoral artery of control, first completes the intervention operation of offside (left or right) artery of lower extremity, prepares row When puncturing homonymy (right or left) arterial intervention operation, retains seal wire and needing to puncture in homonymy (left or right) artery, seal wire stays in In the artery of patient；

Second step：Expander 10 is sent into from 9 uropore of outer sheath；

Third walks：Expander and seal wire are exited, outer sheath 9 stays in puncture side artery；

4th step：Reversed sacculus guide tube body 2 is sent into from the uropore of outer sheath 9 intra-arterial of patient's puncture side, and It is sent to the intravascular suitable position of patient；

5th step：It is inflated from air inlet 7 so that sacculus is full, blocking patient's artery forward blood flow forms closed blood vessel Cavity, then be sent into seal wire from seal wire import 6 and operate seal wire, allow seal wire head to become direction telecentricity from the original proximal part that is directed toward End, operation instrument carry out the interventional treatment of vascular puncture side distal end lesion；

6th step：The seal wire for retaining reverse directions, exits reversed sacculus guide tube body 2 and outer sheath 9；

7th step：Outer sheath 9 and expander are sent into patient vessel along reverse directions seal wire again, exit expander and led Silk, only stays outer sheath, outer sheath direction is turned to from original 180 degree at this time.

Although the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art is come Say, still can with technical scheme described in the above embodiments is modified, or to which part technical characteristic into Row equivalent replacement, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all It is included within the scope of protection of this utility model.
