Description
Technical field
This utility model relates to medical instruments field, is a kind of delivery sheath of the band sacculus that can be guided by Color Sonography.
Background technology
Delivery sheath be a kind of in cardiac minimally-invasive surgery for guiding the common apparatus of plugging umbrella.During traditional interventional cardiac procedures, delivery sheath must be put into right atrium and lack through room and arrive left atrium by medical worker under the guiding of x-ray.But under patient and medical personnel must be exposed to x-ray, as being child or the more weak patient of physical condition, the irradiation of X-ray line also can cause many adverse influences to its health.
Small-sized due to traditional delivery sheath, in view of the at present factor impact such as the level of development of Color Sonography imaging techniques and visual angle in the world, make to be difficult to clearly observe position, delivery sheath leading section by Color Sonography in the process of operation.When the leading section of delivery sheath lacks arrival left atrium through room, the image display of Color Sonography may be the part in delivery sheath non-leading end portion, and medical worker may think this part the leading section of delivery sheath, thus produce erroneous judgement, and continue delivery sheath pushed forward, the leading section causing delivery sheath more sharp-pointed punctures heart tissue, which not only adds and adds operating time, and too increases the risk of operation.
Summary of the invention
The purpose of this utility model is: provide a kind of can by the delivery sheath of the band sacculus of Color Sonography orientation direction.
This utility model is achieved through the following technical solutions: a kind of delivery sheath with sacculus, is characterized in that: it comprises delivery sheath, utricule and tubule;
The leading section outer side surface of described delivery sheath is provided with utricule, and the front end face of delivery sheath head and flushing foremost of utricule, for being tightly connected between the tube wall of delivery sheath and utricule;
Described tubule is arranged in delivery sheath, and the front end of tubule is interconnected through the leading section wall of described delivery sheath and utricule inner chamber, and the afterbody of tubule extends the afterbody of delivery sheath.
Technology comparatively, the beneficial effects of the utility model are:
1, when performing the operation, after utilizing tubule to inject the material that can develop in utricule, utricule slight expansion can be made, increase the volume of utricule, its position can be observed out by Color Sonography with the utricule of developing materials after expansion, and then determine to allow medical worker can determine the position of delivery sheath leading section, avoid delivery sheath to insert taking an advanced study paired heart tissue causing damage;
2, the utricule after expanding makes the leading section passivation of delivery sheath indirectly, and then delivery sheath leading section can be avoided when touching heart tissue, and heart tissue receives damage;
3, when delivery sheath is lacked by room, utilize the expanded size of utricule can measure the scarce size in room, expanded function of the present utility model further.

Label declaration: 1-delivery sheath, 2-utricule, 3-tubule.
Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and this utility model elaborated:
This utility model comprises delivery sheath 1, utricule 2 and tubule 3;
The leading section outer side surface of described delivery sheath 1 is provided with utricule, and the front end face of delivery sheath 1 head and flushing foremost of utricule 2, for being tightly connected between the tube wall of delivery sheath 1 and utricule 2;
Described tubule 3 is arranged in delivery sheath 1, and the front end of tubule 3 is interconnected through the leading section wall of described delivery sheath 1 and utricule 2 inner chamber, and the afterbody of tubule 3 extends the afterbody of delivery sheath 1.
Here, the end face of delivery sheath 1 head and flushing foremost of utricule 2, that delivery sheath 1 head can be accurately positioned on the one hand, after can balloon inflation being ensured on the other hand, the leading section of delivery sheath is passivated, being to prevent material in utricule 2 from flowing out for being tightly connected between the tube wall of delivery sheath 1 and utricule 2, utricule 2 inner chamber amount of substance can being controlled by tubule 3, and then the size of adjustment utricule.
Described delivery sheath 1 and utricule 2 are made up of medical silica-gel material.
In this utility model, at least there are following two kinds of modes in the setting of tubule:
Embodiment 1:
As depicted in figs. 1 and 2, described tubule 3 body abutment is on the inner surface of tube wall of delivery sheath 1, and the afterbody of tubule 3 passes from the mouth of pipe of delivery sheath 1 afterbody.
Embodiment 2:
As shown in Figure 3 and Figure 4, the tube wall that described tubule 3 body is placed in delivery sheath 1 is inner, and the afterbody of tubule 3 passes from the sidewall of delivery sheath 1 afterbody.
Occupation mode of the present utility model is as follows:
During operation, delivery sheath 1 is inserted in the atrium of side and (is generally right atrium, here the experience of medical worker can be relied on to judge), after determining that the front end of delivery sheath arrives right atrium, in utricule 2, the material that can develop slowly is injected by tubule 3, and open Color Sonography simultaneously, under the guiding of color ultrasound, move delivery sheath 1 gradually, the leading section of delivery sheath 1 is lacked through room and enters left atrium.
After the leading section of delivery sheath lacks part through room, can also following operation be carried out, lack size to measure room, concrete operations are, in utricule 2, the material that can develop on a small quantity is injected by tubule 3, such utricule that will make expands by a small margin, afterwards delivery sheath is dragged backward, determine that can delivery sheath extract territory, missing plot, room out, if passable, delivery sheath leading section is so continued to lack through room and enter left atrium, continue through tubule 3 and inject the material that can develop on a small quantity in utricule 2, then above-mentioned steps is repeated, until delivery sheath leading section cannot pumpback, namely the cross-sectional sizes after balloon inflation being described substantially is equal to room and lacks size, by injecting the volume of the material of development, the cross-sectional sizes after balloon inflation can be extrapolated, and then determine that room lacks the size of part.
Although this utility model adopts specific embodiment and alternative thereof illustrate to this utility model and illustrate, only to should be appreciated that otherwise the variations and modifications deviated from scope of the present utility model all can be implemented.Therefore, except being to be understood that the restriction of claim except being enclosed and condition of equivalent thereof, this utility model is not by the restriction of going up in all senses.
