Description
Technical field
It is particularly convex after percutaneous vertbroplasty (PCVP) or percutaneous vertebral body the present invention relates to bone filler delivery instrument
A kind of bone filler delivery pipe with closeouts used in plasty (PCKP).
Background technology
Compression fracture of vertabral body is mainly in the elderly caused by osteoporosis, as aging population deepens continuously,
The patient for suffering from this disease is also increasing sharply, and percutaneous vertbroplasty (PVP) or Percutaneous kyplasty (PKP) exist
Irreplaceable effect is wherein played.At present, the bone filler delivery pipe with closeouts is widely used in vertebroplasty
In, image documentation equipment monitoring under, by external force into the cancellous space of vertebra injection fillers thing (such as bone cement), reach reparation
Vertebral height, strengthens the strength and stability of centrum, reduction of patient pain in back and loin, so as to treat due to vertebra caused by osteoporosis
The purpose of body compression fracture.
The external bone filler delivery pipe with closeouts at present used in vertebroplasty (PCVP or PCKP), example
As Patent No. US779903582 foreign patent application discloses a kind of percutaneous vertebroplasty operating theater instruments, described in it
The bending of bone filler delivery pipe, the delivery pipe hardness in this patent is very high, and this delivery pipe has two kinds of usages, and one is profit
Expanded a cavity in advance in centrum before this with this delivery pipe, the shape of this cavity be similar to it is horn-like, then again toward centrum
Middle perfusion bone filler, and once operation can only irrigate a point, two be direct perfusion bone filler, and one is not expanded in advance
Chamber, and once operation can only irrigate a point, such a delivery pipe expands a cavity in advance, and being shaped as this cavity is horn-like
, cause bone filler skewness in centrum, increase the probability of complication generation and the risk of secondary fracture, then
Such a percutaneous vertebroplasty operating theater instruments of person, needs to extract in operation the fuse in delivery pipe, the effect of fuse be for
Prevent big broken bone enter delivery cannula block bone filler injection canal integrated operation it is complicated, extend operating time,
Add operation risk.
For the problems of the prior art, one kind is needed badly using flexible, it is simple to operate, operating time can be shortened, and
Multi-point injection can be realized, and then the bone filler delivery cannula of complication rate can be reduced.
The content of the invention

Depoling, reduces the operating procedure of apparatus, can equally realize the purpose for preventing larger broken bone from entering delivery pipe.
In use, as shown in figure 4d, the outer tube 1 is provided with outer tube mark line 13, and the closeouts 14 are covered
The outer injection orifice 10, the closeouts injection orifice 140 staggers with the outer injection orifice 10, and now described outer injection orifice 10 is closed
Close, when there is bone filler to enter the outer tube 1, bone filler promotes the closeouts 14 further to compress the elastic component 15
Along the inwall of the outer tube 1 to the distal movement of the outer tube 1, the outer injection orifice 10 and the closeouts injection orifice are realized
140 overlap, and realize opening of the outer injection orifice 10 in target location.Puncture needle handle mark line 31 is provided with puncture needle handle 3,
The delivery pipe is inserted into puncture needle syringe, now the delivery pipe mark line a is overlapped with puncture needle handle mark line 31,
By adjusting outer tube handle 3, outer tube mark line 13 is moved reciprocatingly relative to puncture needle handle mark line 31, conveying is made successively
Pipe mark line b ... n is overlapped with puncture needle handle mark line 31 respectively, realizes the outer injection orifice 10 of delivery pipe constantly from distal end proximally
It is mobile, after each outer tube mark line 13 is overlapped with puncture needle handle mark line 31, selected point is irrigated, repeatedly regulation,
Multi-point injection.
Finally it should be noted that the foregoing is only the preferred embodiment of the present invention, this is not limited to
Invention, any modifications, equivalent substitutions and improvements made within the spirit and principles of the invention etc., it should be included in this hair
Within bright protection domain.
