Abstract
The utility model discloses a vertebra perforator which comprises a sleeve tube and a needle body, wherein a grab handle is fixedly arranged on the tail portion of the sleeve tube, the needle body can be movably inserted in the sleeve tube, and the head portion of the needle body is provided with a blade point. The vertebra perforator can reach the operative needed intensity of the needle body. The blade point of the head portion of the needle body is improved, so that puncturing is easy and then time of operation is saved.
Description
Technical field
This utility model relates to a kind of vertebra perforator, belongs to the medical apparatus and instruments apparatus.
Background technology
At present, compression fracture of vertabral body is the modal complication of sufferers of osteoporosis face, and open operation treatment wound in the past is large, and complication is many.And percutaneous vertebroplasty (PVP) and percutaneous balloon kyphoplasty (PKP) are rapidly novel micro-wound surgical operations of spinal surgery development in recent years, directly inject or the implants such as bone cement, artificial bone of reinjecting by balloon expandable first in compressed vertebral by percutaneous, thereby strengthen the mechanical stability of pathological changes vertebral body, clinical practice is the verified effective therapeutic effect of its reliable and stable, fast Lai, and few intercurrent disease.And the vertebra perforator is in micro-wound surgical operation, uses for vertebral body puncture, and the needle body of common vertebra perforator is thin not, and the needle body head is more mellow and fuller, and is cumbersome during puncture, affected operating time.
Summary of the invention
The purpose of this utility model is the defective that overcomes prior art, thereby provides a kind of easy puncture to save the vertebra perforator of operating time.
The technical scheme that realizes this utility model purpose is: a kind of vertebra perforator, comprise sleeve pipe and needle body, and the afterbody of sleeve pipe is fixed with lever, and needle body is inserted in the sleeve pipe movably, and the head of described needle body has blade tip.
Further, the blade tip of described needle body is a basil structure.
Further, the blade tip of described needle body is the symmetrical structure of two-edged face, and described sword face is formed by connecting by mutual angled two inclined-planes.
Further, the blade tip of described needle body is three basil syndetons at an angle to each other.
After having adopted technique scheme, this utility model can reach the intensity of the required needle body of operation, and the blade tip of needle body head is improved, and is more prone to so that puncture, thereby has saved operating time.

Fig. 1 is the structural perspective of the first structure of vertebra perforator of the present utility model;
Fig. 2 is the axonometric chart of the second structure of the needle body head of vertebra perforator of the present utility model;
Fig. 3 is the axonometric chart of the third structure of the needle body head of vertebra perforator of the present utility model.
The specific embodiment
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail this utility model according to specific embodiment also by reference to the accompanying drawings,
Embodiment one
As shown in Figure 1, a kind of vertebra perforator comprises sleeve pipe 1 and needle body 2, and the afterbody of sleeve pipe 1 is fixed with lever 3, and needle body 2 is inserted in the sleeve pipe 1 movably, and the head of needle body 2 has blade tip 2-1.The blade tip 2-1 of needle body 2 is a basil structure.
Embodiment two
As shown in Figure 2, a kind of vertebra perforator comprises sleeve pipe 1 and needle body 2, and the afterbody of sleeve pipe 1 is fixed with lever 3, and needle body 2 is inserted in the sleeve pipe 1 movably, and the head of needle body 2 has blade tip 2-1.The blade tip of needle body 2 is the symmetrical structure of two-edged face, and described sword face is formed by connecting by mutual angled two inclined-planes.
Embodiment three
As shown in Figure 3, a kind of vertebra perforator comprises sleeve pipe 1 and needle body 2, and the afterbody of sleeve pipe 1 is fixed with lever 3, and needle body 2 is inserted in the sleeve pipe 1 movably, and the head of needle body 2 has blade tip 2-1.The blade tip 2-1 of needle body 2 is three basil syndetons at an angle to each other.
This utility model can change the diameter of needle body into 3.0 millimeters or 3.5 millimeters, and does not affect the intensity of needle body, and the blade tip of needle body head is improved, and is more prone to so that puncture, thereby has saved operating time.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to this utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
