Abstract
The invention relates to a sacculus with a catheter propelling sleeve, comprising a sacculus body, a sacculus catheter and a sacculus handle, wherein the both ends of the sacculus catheter are respectively connected with the sacculus body and the sacculus handle; the sacculus catheter is sleeved with the elastic catheter propelling sleeve detachably connected with the sacculus handle; and the inner diameter of the tail end of the elastic catheter propelling sleeve, which is close to the sacculus handle, is matched with the sacculus handle. The invention enhances the transmission efficiency of the propelling force of the sacculus catheter by arranging the catheter propelling sleeve on the sacculus catheter so that the propelling force is more effectively transmitted to the sacculus body, thereby being beneficial to the convenient and fast operation of the sacculus catheter, enhancing the integral throughout capacity of the sacculus and the work efficiency.
Description
Technical field
The present invention is specifically related to a kind of sacculus that conduit pushes cover that has.
Technical background
After the nineties in 20th century, Wicresoft's interventional therapy angiopathy [minimally invasive therapy] technology begins to have obtained widely to use, and has been acknowledged as one of the most effective means of treatment cardiovascular and cerebrovascular disease.At different vascular lesions and requirement, research worker and doctor develop the novel vascular stent of superior performance jointly, and have obtained the achievement that attracts people's attention.
Along with the innovation and the development of minimally invasive medical technology, support expansion completely is beneficial to the incidence rate that prevents restenosis, reduces target lesion reconstruction and stent thrombosis.Studies show that support not exclusively expansion is the independent hazard factor of postoperative generation stent thrombosis.Because expansion can obviously increase the minimum support area of MSA[Minimum Stent Area behind the non-compliant balloon support inner high voltage] and MSD[Minimum Stent Diameter support minimum diameter], therefore the back expansion can increase DES[Drug Eluting Stent bracket for eluting medicament greatly] the desirable success rate of implanting.Therefore, the scope of application of sacculus more and more widely, usage quantity grows with each passing day.In the middle of operation, the doctor is undertaken by transporting of the foley's tube that is connected with sacculus pushing or return when removing sacculus normally, but, have the following problem that influences the foley's tube smooth delivery of power at present: one, the foley's tube external diameter is thinner, usually between 2.0～2.55F (F intervention field abroad is commonly used to represent the usage of conduit diameter, and conversion relation is 1mm=3F); Two, the doctor wears sterile glove, and glove are stained with medicinal liquid, disinfectant solution or blood stains etc., and course of conveying skids easily, normally the carrying out of influence operation.
In order to improve the convenience that the doctor operates foley's tube, foley's tube is carried out some new designs and improvement is necessary.
Summary of the invention
The objective of the invention is to improve the operability of foley's tube, provide a kind of doctor of being convenient to carry out the sacculus that has conduit propelling movement cover that sacculus pushes.
A kind of conduit that has pushes the sacculus that overlaps, comprise sacculus body, foley's tube and sacculus handle, the two ends of described foley's tube connect sacculus body and sacculus handle respectively, be arranged with one on the described foley's tube and push cover with the dismantled and assembled elastic catheter that is connected of sacculus handle, this conduit pushes the leading portion and the foley's tube coupling of cover internal diameter, terminal and sacculus handle coupling.
The outer surface that described conduit pushes cover is provided with to increasing the groove or the projection of frictional force, prevents to skid when firmly pushing.
The projection of described outer surface is a cylindricality.
Described elastic catheter pushes cover and pushes cover for medical silastic vessel, and its shaft section is trapezoidal.
It is 25.4mm～30.0mm that described conduit pushes condom height degree, holds to be fit to pinching of thumb, forefinger and middle finger.
The leading portion that described conduit pushes the cover internal diameter is 3～4F, and the end of internal diameter is 14～16F.Can not be free to slide along the sacculus conveying lever when finger is not executed axial force, the time spent is not placed in foley's tube handle place by the end of internal diameter.
The end that described conduit pushes the cover internal diameter is meant that conduit pushes cover internal diameter 1/4 section near the sacculus handle.
The opening of the end of described internal diameter is contraction shape, helps the sacculus handle that better is locked.
The present invention has the following advantages:
(1) the present invention is provided with a conduit and pushes cover providing on the foley's tube, improve the propelling movement power conduction efficiency of foley's tube, make propelling movement power more effectively be passed to the sacculus body, help the operation readiness of foley's tube, increase the whole handling capacity of sacculus, increase work efficiency.
(2) the present invention selects for use elastic material and outer surface to have the conduit propelling movement cover of big frictional force, can help the foley's tube of holding with a firm grip, is convenient to carry.
(3) end of the internal diameter of conduit propelling movement cover of the present invention adopts the design of contraction shape to be set in above the sacculus handle in the time need not pushing sacculus, does not hinder doctor's operate as normal.
(4) the present invention is rational in infrastructure, humanization designing, for calcification, tortuous, become angle, challenge pathological changes such as extremely narrow that the high suitability is arranged, serve doctor and patient effectively.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the cross-sectional view that conduit of the present invention pushes cover.
Specific embodiments
As shown in Figure 1, the invention provides a kind of sacculus that conduit pushes cover that has, comprise sacculus body 1, foley's tube 2 and sacculus handle 3, the two ends of described foley's tube 2 connect sacculus body 1 and sacculus handle 3 respectively, be arranged with one on the described foley's tube 2 and push cover 4 with the dismantled and assembled medical silastic vessels that are connected of sacculus handle 3, it is 25.4mm～30.0mm that described conduit pushes condom height degree, holds to be fit to pinching of thumb, forefinger and middle finger.
As shown in Figure 2, the outer surface that this conduit pushes cover 4 is provided with to increasing the column-shaped projection 5 of frictional force, prevents to skid when firmly pushing, and shaft section is trapezoidal.
Leading portion internal diameter 6 and foley's tube 2 couplings are 3～4F, and terminal internal diameter 7 and sacculus handle 3 couplings near 1/4 section of the internal diameter of sacculus handle are 15F, and the opening of the end of described internal diameter is and shrinks shape, and port is 14F.The naturalness conduit propelling movement cover 4 of not executing axial force at finger can be free to slide along foley's tube 2, and the time spent can not be placed in foley's tube handle 3 places by the end of internal diameter.
