Description
Technical field
The utility model relates to a kind of removable locking device and foley's tubes.
Background technique
China human mortality aging is on the rise, and the compression fracture of vertabral body patient of osteoporosis and its initiation increases year by year,
Elderly patients to life expectancy and quality of life it is continuous pursue, income level of resident is continuously increased so that selection centrum at
The patient of the minimally invasive Surgery compression fracture of vertabral body of shape can be more and more.It is convex after cooperation balloon angioplasty conduit
The progress of plasty, vertebral body balloon dilating catheter also generate therewith.Balloon catheter for expanding vertebra is and vertebral plasty instrument Bao Lian
It closes and uses, form channel suitable for Percutaneous kyplasty, restore vertebral height, form bone cement filling cavity.
Service aisle is used together in balloon catheter for expanding vertebra congregation vertebral plasty instrument packet, the size of warning line with match
The working channel sizes of set are identical.The service aisle length of different manufacturers difference, so that the vertebral body augmentation of different manufacturers
Various sizes of warning line is printed on foley's tube product, and doctor is during operation, it is necessary to use is identical with warning linear dimension
Service aisle is performed the operation, and warning line can just play a warning role, and warning line is control balloon position, although reaching warning
After line position, product can not be fixed, slightly be moved, position is not just right, so that balloon position is inaccurate.
As shown in Figure 1.Existing balloon catheter for expanding vertebra be by developing mark, core pipe, sacculus, outer tube 10, sheath,
Handleset, warning line 20 form.It will be seen from figure 1 that sacculus is by outer tube wall, core tube wall, sheath, Handleset, ball
One confined space of capsule cavity composition.Outer tube outer wall has a warning line 20 to sacculus front end.
Figure it is seen that balloon catheter for expanding vertebra is used cooperatively with service aisle 30, warning line 20 to sacculus it
Between size be just service aisle 30 length.
From Fig. 3,4 as can be seen that two warning lines 20 are had on the producer's balloon catheter for expanding vertebra having, as first police
When ring line 20 is located at the position (Fig. 4), sacculus front end arrived the end of service aisle 30, observe developing mark according to fluoroscopy images
Position or (such as Fig. 5) determines balloon position when continuing forward impelling to Article 2 20 position of warning line, expanded, together
When supporting wire component need to be pulled out, perform the operation.But sacculus can not be fixed on the position that arrived, while also be not easy to take out
Supporting wire component, may be slightly once the dynamic position for moving sacculus.
In conclusion an either warning line 20 or two warning lines on existing balloon catheter for expanding vertebra product
20, silk-screen size slightly deviation will do over again again debugs again, so that production process is cumbersome, not only reduces productivity,
And there is processing risk, while doctor cannot select the service aisle 30 of different manufacturers during operation without alternative, operate
Get up inconvenience.And our new invention exactly solves these problems.
