Description

Bone filler delivery pipe with closeouts
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
In view of the drawbacks described above of prior art, the technical problems to be solved by the invention are to provide a kind of bone with closeouts Filler delivery pipe, prevents the injection canal that broken bone big when apparatus enters human body enters bone filler through sleeve pipe injection orifice from causing Block, it is simple to operate flexible, multi-point injection is realized by the method for delivery pipe of dropping back.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of bone filler delivery pipe with closeouts, including outer tube, the outer tube that is fixedly connected with the near-end of the outer tube Handle and closeouts, the outer tube include the fixed bend tune of distal portions and the straight section of proximal part, the fixed bend tune Scheduled type has fixed angle of bend, and the tube wall of the distal portions of the fixed bend tune is provided with 1 outer injection orifice, institute State the distal end closing of outer tube, the closeouts, which are arranged in the outer tube, is used to closing the outer injection orifice, the closeouts by The pressure of the bone filler conveyed in the outer tube can realize the outer injection orifice relative to the outer injection orifice dislocation movement Opening in target location.
The purpose of the present invention can also further be realized by following technical scheme:
It is preferred that, elastic component is also included in the pipe of the distal outer tube part, the closeouts pass through the elastic component The distal end of the outer tube is fixed on, the closeouts cover the outer injection orifice, the closure when the elastic component non-stress During part stress, the elastic component is compressed into and drives the closeouts to be moved relative to the outer tube, realizes the outer injection Opening of the hole in target location.
It is preferred that, one closeouts injection orifice is set in the near-end of the closeouts, when the non-stress when institute of the elastic component State closeouts injection orifice with the outer injection orifice to stagger, the elastic component is compressed into and driven described during the closeouts stress Inwall of the closeouts along the outer tube is to the distal movement of the outer tube, the closeouts injection orifice and the outer injection orifice weight Close, realize opening of the outer injection orifice in target location.
It is preferred that, the closeouts are cylindrical metal structural member or cylindric macromolecular structure part or cylindric flexibility Part.
It is preferred that, the elastic component is spring.
It is preferred that, the closeouts are interference fitted with the outer injection orifice.
It is preferred that, the closeouts are cylindrical metal structural member or cylindric macromolecular structure part or cylindric flexibility Part.
It is preferred that, the closeouts include compressible material part and surface hard part, during the non-stress of the surface hard part The outer injection orifice is covered, the compressible material part, the compressible material part band are extruded during the surface hard part stress Dynamic distal movement of inwall of the surface hard part along the outer tube to the outer tube, realizes the outer injection orifice in target position The opening put.
It is preferred that, the fixed bend tune is by elastomeric material, memory alloy material or elastomeric material and memorial alloy material The combination of material is made.
It is preferred that, the near-end of the fixed bend tune is fixedly connected with the distal end of the straight section.
Compared with the existing technology, advantages of the present invention and progress are as follows:
The bone filler delivery pipe with closeouts of the present invention only has outer tube so that patient is when using apparatus without withdrawing Fuse, reduces the operating procedure of apparatus, can equally realize the purpose for preventing larger broken bone from entering delivery pipe.
The bone filler delivery pipe with closeouts of the present invention sets closeouts to be used to close outer injection orifice in outer tube, leads to The pressure for crossing the bone filler of conveying in the outer tube promotes the closeouts motion to realize the outer injection orifice in target location Opening, it is simple to operate.
Moreover, the bone filler delivery pipe with closeouts of the present invention, is realized many by the method for overall delivery pipe of dropping back Point injection, it is easy to operate, complication rate is reduced, operation risk is reduced.
