Abstract
The invention provides a medical appliance, in particular a technical proposal of an applier used for injecting bone material into a centrum. The technical proposal provides a material injecting head which is made of a material corresponding with the biocompatibility requirement and provided with a material injecting hole, and a soft pocket which is made of the material corresponding with the biocompatibility requirement, wherein, the open end of the pocket is fixedly connected with the material injecting head. A material injecting tube with the material injecting hole is arranged on the material injecting head, the open end of the pocket is sleeved on the material injecting tube, a locking sleeve is arranged outside the pocket, and the locking sleeve and the material injecting tube clamp the open end of the pocket; therefore, the fixed connection between the material injecting head and the open end of the pocket is realized. Screw threads are formed at the upper end of the material injecting tube; a positioning table is arranged at the lower end of the screw threads; a locking table is arranged at the lower end of the positioning table; the positioning table and the locking table are positioned at the upper middle part of the material injecting tube. The pocket is made of a pouched material or a tubular material, one end of which is locked by a dead ring. The material which corresponds with the biocompatibility requirement is titanium alloy, nontoxic engineering plastics or polyester filament.
Description
Technical field:
What the present invention relates to is a kind of medical apparatus, especially a kind of tucker that injecting bone material is used in vertebral body.
Background technology:
At present, the patient of compression fracture is appearred in vertebral body, all need vertebral plasty, reset, and in the vertebral plasty operation, just need in the vertebral body of subsiding, inject as bone material such as bone cements.In the prior art, injecting bone material be by infusion appliance under the supervision of actinoscopy X, bone material is directly injected affected area, because being flow-like, bone material injects, this injection process needs the operator extremely careful and careful, in case misoperation, bone material is excessive or leak into other position, will cause contingency, this is the existing in prior technology weak point.
Summary of the invention:
Purpose of the present invention, be exactly at the existing in prior technology deficiency, and provide a kind of tucker technical scheme that injecting bone material is used in vertebral body, this scheme adopts a combination that has the material feeding head and a soft pocket of material hole, when implementing the vertebral plasty operation, tucker is inserted affected area, material hole injecting bone material in pocket by the material feeding head then, because being softish shape that fully can be as required, pocket is shaped, and bone material is in pocket, therefore, bone material will never flow arbitrarily, has also just avoided bone material can flow to unwanted position.
This programme is realized by following technical measures: the characteristics of this programme are the soft pockets that material that the material feeding head that has material hole made of the material that has a usefulness to meet biocompatibility requirement and usefulness meet biocompatibility requirement is made, and the opening of described pocket and described material feeding are fixedlyed connected.The concrete characteristics of this programme also have, described material feeding head is the filling tube that the material feeding head has a band material hole with fixedlying connected of pocket opening, described pocket opening is sleeved on the filling tube, and the locking cover is arranged outside pocket, and this locking cover and filling tube clamp the opening of pocket.There is screw thread upper end at described filling tube, and there is positioning table the lower end of screw thread, and there is the locking platform lower end of positioning table, and the position of described positioning table and locking platform is in the middle and upper part of filling tube.Described pocket is a bag shape material finish mix bag.Described pocket is the pocket of tubular material one end with dead ring locking.The described material that meets biocompatibility requirement is titanium alloy, non-toxic engineering plastic or polyester filament.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because in this scheme.Adopt a combination that has the material feeding head and a soft pocket of material hole, and the opening of described pocket and described material feeding are fixedlyed connected.The tucker of this structure, when implementing the vertebral plasty operation, tucker is inserted affected area, material hole by the material feeding head injects fluidic bone material in pocket then and since pocket be softish fully can be as required shape be shaped, fixing, reach vertebral plasty, the requirement that resets, and bone material is to be infused in can not outflow in the pocket, therefore, bone material will never flow arbitrarily, has also just avoided bone material can flow to unwanted position and has caused the accident.This shows that the present invention compared with prior art has outstanding substantive distinguishing features and obvious improvement, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the part sectional structure sketch map of the specific embodiment of the invention.
The structural representation that Fig. 2 adopts the specific embodiment of the invention of tubular materials processing partly to analyse and observe for pocket.
Among the figure, 1 is pocket, and 2 are the locking cover, and 3 are the material feeding head, and 4 is filling tube, and 5 is material hole, and 6 is positioning table, and 7 are the locking platform, and 8 is dead ring.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
By accompanying drawing as can be seen, the tucker that injecting bone material is used in the body of this programme has the material feeding that has the material hole 53 and soft pockets 1 made from the polyester filament material that adopt titanium alloy or non-toxic engineering plastic to make, and the opening of described pocket 1 and described material feeding 3 fixedlyed connected.Described material feeding 3 and fixedlying connected of pocket 1 opening are the filling tubes 4 that material feeding 3 has a band material hole 5, described pocket 1 opening is sleeved on the filling tube 4, locking cover 2 is arranged outside pocket 1, this locking cover 2 and filling tube 4 clamp the opening of pockets 1, with material feeding 3 and pocket 1 sealing and fixing together.Described filling tube 4 is that the upper end has screw thread to be used for telescopic joint with injecting bone material, in the lower end of screw thread positioning table 6 is arranged, and locking platform 7 is arranged in the lower end of positioning table 6, and the position of described positioning table 6 and locking platform 7 is in the middle and upper part of filling tube 4.Described pocket 1 is a bag shape material finish mix bag 1, or tubular material one end is locked finish mix bags 1 with dead ring 8.
