Abstract
The invention relates to a vertebra reduction testing apparatus for medical operation. The vertebra reduction testing apparatus comprises a pressure injection device, a developer injection device and a puncture device. The puncture device comprises a puncture lever and bladders arranged at the end of the puncture lever. The pressure injection device is communicated with the bladders through a catheter. The bladders include a main bladder and an auxiliary bladder; the main bladder is connected with the pressure injection device through a main catheter, the auxiliary bladder is connected with the pressure injection device through an auxiliary catheter, and the main catheter and the auxiliary catheter are communicated with the catheter through a flow divider. Outer walls of the main bladder and the auxiliary bladder are connected with developer coatings which are connected with the developer injection device through a side catheter. A first pressure gauge is connected to the catheter, and a second pressure gauge is connected to the side catheter. According to the vertebra reduction testing apparatus for medical operation, operation is simplified, time is shortened and cost is lowered on the basis of unilateral puncture. As developer is injected to surfaces of the bladders, usage of the developer is reduced while observation effect during shooting is improved, and operation reliability is improved.
Description
Technical field
The present invention relates to medical instruments field, particularly relate to a kind of medical instruments for bone surgery.
Background technology
Percutaneous kyplasty (PKP) is a kind of novel Minimally Invasive Surgery being used for the treatment of osteoporotic compression fracture, can alleviate fracture pain rapidly.Be specially before injection bone cement, by perspective, with the bone dilator of an expansion expansiveness, Vertebral Compression place expanded, thus reach and raise terminal plate of vertebral body, recover vertebral height, the object of the kyphosis deformity of correction spinal column.
In prior art, PKP operation adopts bilateral vertebral pedicle puncture, and two sacculus expands balanced recovery intervertebral height simultaneously.But the art formula operating time of bilateral puncture, two balloon expandable is long, surgery cost is expensive.Partial spinal column surgeon is for reducing surgery cost for this reason, the KP operation of the capable bilateral puncture of application single saccule, but its defect is that operating time extends and radiation exposure is more, and operating difficulty is large, risk is higher.In above-mentioned KP operation, all need to inject developing agent in sacculus, so that carefully study entry point and the angle of needle track on CT image film, and form fluoroscopy images clearly.Need when injecting developing agent in sacculus all to be filled by sacculus or mix with original filling liquid, when all filling, the consumption of developing agent is comparatively large, and when mixing is filled, developing agent can not be uniformly distributed in balloon surface, causes the display effect of film poor.
Summary of the invention
The above-mentioned shortcoming that the applicant exists for prior art, carries out studying and designing, and provides a kind of and reduces operation cost, has that the time is short, reliability is high and the bone vertebra reset assay device used for medical procedures of convenient injection developing agent.
The technical solution adopted in the present invention is as follows:
A kind of bone vertebra reset assay device used for medical procedures, comprise pressure injection apparatus, dye injection device and sting device, sting device comprises puncturing lever and is installed on the sacculus of puncturing lever end, pressure injection apparatus is communicated with sacculus by conduit, described sacculus comprises cue ball capsule and auxiliary sacculus, cue ball capsule is connected with described pressure injection apparatus by teaching pipe respectively by main pipe, auxiliary sacculus, and main pipe and guidance pipe are by flow divider and tubes connection; The outer wall of described cue ball capsule and auxiliary sacculus is also connected with developer layer, and described developer layer is connected with described dye injection device by limit conduit;
Described conduit is connected with the first Pressure gauge, described limit conduit is connected with the second Pressure gauge.
Beneficial effect of the present invention is as follows:
The present invention adopts one-sided puncture, can reach the effect same during puncture of original bilateral, simplify operation, shortens the time, reduces cost; By dye injection in balloon surface, decrease the consumption of developing agent on the one hand, improve observing effect during film making on the other hand, improve the reliability of operation.

In figure: 1, pressure injection apparatus; 2, dye injection device; 3, puncturing lever; 4, sacculus; 41, cue ball capsule; 42, auxiliary sacculus; 5, conduit; 51, main pipe; 52, pipe is taught; 6, limit conduit; 7, the first Pressure gauge; 8, the second Pressure gauge; 9, developer layer; 10, flow divider.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, the bone vertebra reset assay device used for medical procedures of the present embodiment, comprise pressure injection apparatus 1, dye injection device 2 and sting device, sting device comprises puncturing lever 3 and is installed on the sacculus 4 of puncturing lever 3 end, pressure injection apparatus 1 is communicated with sacculus 4 by conduit 5, sacculus 4 comprises cue ball capsule 41 and auxiliary sacculus 42, cue ball capsule 41 is connected with pressure injection apparatus 1 by teaching pipe 52 respectively by main pipe 51, auxiliary sacculus 42, and main pipe 51 is connected with conduit 5 by flow divider 10 with guidance pipe 52; The outer wall of cue ball capsule 41 and auxiliary sacculus 42 is also connected with developer layer 9, and developer layer 9 is connected with dye injection device 2 by limit conduit 6;
Conduit 5 being connected with the first Pressure gauge 7 for detecting injection pressure in sacculus 4, limit conduit 6 being connected with the second Pressure gauge 8 for detecting developing agent pressure.
When the present invention uses, the puncturing lever 3 of non-injection injection liquid is inserted bone vertebra repair place, rotate flow divider 10, main pipe 51 is communicated with conduit 5, by pressure injection apparatus 1, injection (being generally normal saline) is injected cue ball capsule 41, after vertebral body recovers by cue ball capsule 41, stop injection, record the force value of the first Pressure gauge 7 and the volume of injection; Rotating flow divider 10 makes guidance pipe 52 be communicated with conduit 5, by pressure injection apparatus 1, injection is injected auxiliary sacculus 42 equally; By dye injection device 2, developing agent is injected developer layer 9 by limit conduit 6, during injection, observe the force value of the second Pressure gauge 8, stop injecting when its force value is equal with the first Pressure gauge 7; Take CT film after injection developing agent, observe bone vertebra state.
The present invention adopts one-sided puncture, can reach the effect same during puncture of original bilateral, simplify operation, shortens the time, reduces cost; By dye injection in balloon surface, decrease the consumption of developing agent on the one hand, improve observing effect during film making on the other hand, improve the reliability of operation.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention is see claim, and when without prejudice to spirit of the present invention, the present invention can do any type of amendment.
