Description
Technical field:
The utility model relates to the medical apparatus and instruments that a kind of operation on vertebra is used, especially a kind of vertebra expansion, tucker.
Background technology:
In the prior art, technique known is the vertebra dilator that is used in, the contrast agent that existing dilator has catheter block and special-purpose contrast agent to inject injects seat, on catheter block, be fixed with inner catheter and outer catheter, contrast agent is to inject sacculus by the contrast agent passage between inner catheter and the outer catheter, sacculus then is to bond together with outer catheter, and this just makes that being connected of sacculus and outer catheter is unreliable, and this is the existing in prior technology weak point.
Summary of the invention:
The purpose of this utility model, be exactly at the existing in prior technology deficiency, a kind of vertebra is expanded, the tucker technical scheme and provide, this scheme adopts sacculus to make integrative-structure or utilize union joint to be connected with outer catheter, guaranteed the reliability that sacculus is connected with outer catheter, and can use in expansion operation and filling operation vertebral compression fracture.
This programme is realized by following two technical measures:
First embodiment:
The vertebra expansion of this programme, tucker, include inner catheter and outer catheter and fix the catheter block of two conduits, at the inner catheter inner chamber guide pin is arranged, this guide pin is fixed on the guide pin seat, catheter block is connected with the guide pin seat, on catheter block, also have contrast agent to inject seat, the inner chamber of contrast agent injection seat communicates with the contrast agent passage between inner catheter and the outer catheter, sealing that useful soft material is made on the top of outer catheter or gas-pervious sacculus, the characteristics of this programme are that described outer catheter and sacculus are integrative-structures.The concrete characteristics of this programme also have, and also have the sacculus protective layer at described sacculus outer wall.
Second embodiment:
The vertebra expansion of this programme, tucker, include inner catheter and outer catheter and fix the catheter block of two conduits, at the inner catheter inner chamber guide pin is arranged, this guide pin is fixed on the guide pin seat, catheter block is connected with the guide pin seat, on catheter block, also have contrast agent to inject seat, the inner chamber of contrast agent injection seat communicates with the contrast agent passage between inner catheter and the outer catheter, sealing that useful soft material is made on the top of outer catheter or gas-pervious sacculus, the characteristics of this programme are that described sacculus is to be fixed on the union joint, and union joint is connected with described outer catheter again.The concrete characteristics of this programme also have, and described union joint is to adopt to be threaded with being connected of outer catheter.Described union joint is to adopt bonding connection with being connected of outer catheter.Described sacculus can be monolayer or also have the sacculus protective layer at the sacculus outer wall.
The beneficial effect of this programme can be according to the narration of above-mentioned two schemes is learnt, because in the first string, what outer catheter and sacculus adopted is integrative-structure, and in second scheme, outer catheter and sacculus adopt is being connected of union joint and outer catheter by being fixed with sacculus.This structure makes the syndeton of sacculus and outer catheter more reasonable and reliable, has guaranteed the reliability that sacculus is connected with outer catheter.This shows that this utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the structural representation of first specific embodiment of this utility model.
Fig. 2 has the structural representation of sacculus protective layer for Fig. 1.
Fig. 3 is the structural representation of second specific embodiment of this utility model.
Among the figure, 1 is the guide pin seat, and 2 for contrast agent injects seat, and 3 is catheter block, and 4 is guide pin, and 5 is inner catheter, and 6 is outer catheter, and 7 is the contrast agent passage, and 8 is sacculus, and 9 is the sacculus protective layer, and 10 is union joint.
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 two specific embodiment.
First specific embodiment:
By attached Fig. 1 and 2 as can be seen, the vertebra expansion of this programme, tucker, inner catheter 5 and outer catheter 6 are arranged and fix the catheter block 3 of two conduits, at inner catheter 5 inner chambers guide pin 4 is arranged, this guide pin 4 is fixed on the guide pin seat 1, catheter block 3 is connected with guide pin seat 1, on catheter block 3, also have contrast agent to inject seat 2, the inner chamber of contrast agent injection seat 2 communicates with the contrast agent passage 7 between inner catheter 5 and the outer catheter 6, useful soft material maybe can absorb sealing or the gas-pervious sacculus 8 that material is made on the top of outer catheter 6, and described outer catheter 6 of this programme and sacculus 8 are integrative-structures.Also can also have sacculus protective layer 9 at described sacculus 8 outer walls.
Second specific embodiment:
As seen in Figure 3, the vertebra expansion of this programme, tucker, inner catheter 5 and outer catheter 6 are arranged and fix the catheter block 3 of two conduits, at inner catheter 5 inner chambers guide pin 4 is arranged, this guide pin 4 is fixed on the guide pin seat 1, catheter block 3 is connected with guide pin seat 1, on catheter block 3, also have contrast agent to inject seat 2, the inner chamber of contrast agent injection seat 2 communicates with the contrast agent passage 7 between inner catheter 5 and the outer catheter 6, sealing that useful soft material is made on the top of outer catheter 6 or gas-pervious sacculus 8, the described sacculus 8 of this programme is to be fixed on the union joint 10, union joint 10 is connected with described outer catheter 6 again, described union joint 10 can adopt and meet the biocompatibility metal material or non-metallic material is made, and described union joint 10 is to adopt to be threaded with being connected of outer catheter 6.Certainly, union joint 10 can adopt bonding connection with being connected also of outer catheter 6.And can be monolayer or also have sacculus protective layer 9 at sacculus 8 outer walls at described sacculus 8.
