Abstract
The invention provides a technical scheme of a puncture needle for the centrum. The puncture needle for the centrum comprises an outer sleeve tube, an outer sleeve tube handle, a needle core and a needle core handle, wherein the needle core and the needle core handle are inside the outer sleeve tube. The puncture needle for the centrum is characterized in that a puncture blade head is arranged at the top end of the outer sleeve tube, the outer sleeve tube at the upper portion of the puncture blade head is provided with a lateral opening communicated with an inner cavity of the outer sleeve tube, and the puncture blade head between the edge of the lateral opening of the puncture blade head and the corresponding inner wall of the outer sleeve tube is provided with an arc guide surface. The puncture needle for the centrum is further characterized in that the top end of the need core is an elliptic spherical surface, and the arc guide surface of the puncture blade head is an elliptic spherical surface as well.
Description
Technical field
What the present invention relates to is a kind of medical orthopedic operating apparatus, especially a kind of vertebral body puncture needle.
Background technology
In the prior art, the technical scheme that approaches the most with the application is the conventional vertebral body puncture needle in use, and conventional vertebral body puncture needle is all that the top of nook closing member has puncture sword head, punctures with nook closing member, trocar sheath is a working column, and the top of trocar sheath is a mouth of pipe.Because puncture needle need to enter vertebral body along pedicle of vertebral arch, sometimes the position puncture needle that needs to perform the operation does not reach, therefore, need to adopt the means such as bilateral puncture, this has not only increased the workload of operation puncturing, and having increased the operating theater instruments expense of patient's costliness, this is the existing weak point of prior art.
Summary of the invention
Technical problem to be solved by this invention, be exactly for the existing deficiency of prior art, and provide a kind of vertebral body puncture needle technical scheme, this scheme adopts puncture sword head on the top of trocar sheath, on the trocar sheath on puncture sword head top, side opening is arranged, utilize side opening to select the most approaching position of operation that needs to perform the operation, and nook closing member just play the effect of strengthening trocar sheath intensity when puncture.
This programme is achieved by the following technical measures: vertebral body includes nook closing member and nook closing member handle in trocar sheath and trocar sheath handle and trocar sheath with puncture needle, the characteristics of this programme are that puncture sword head is arranged on the top of described trocar sheath, on the trocar sheath on puncture sword head top, the side opening that communicates with the trocar sheath inner chamber is arranged, on the puncture sword head between the outer sleeve inner wall corresponding with side opening of the side opening limit of described puncture sword head, arc guide surface is arranged.The concrete characteristics of this programme also have, and the top of described nook closing member is ellipsoidal surface.Arc guide surface on described puncture sword head is ellipsoidal surface.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because in this scheme being has puncture sword head on the top of trocar sheath, on the trocar sheath on puncture sword head top, the side opening that communicates with the trocar sheath inner chamber is arranged, on the puncture sword head between the outer sleeve inner wall corresponding with side opening of the side opening limit of described puncture sword head, arc guide surface is arranged.This structure, the function of puncture are to be reached by the puncture sword head on trocar sheath, and therefore, puncture is to be completed by trocar sheath, and nook closing member just plays the effect of strengthening trocar sheath intensity when puncture, and this is just in time opposite with prior art.And the position of performing the operation is in the corresponding position of trocar sheath side opening, can reach the existing vertebral body puncture needle operative site that is beyond one's reach.For example, patient's fracture is adding in pedicle of vertebral arch one side, need to carry out the balloon operation treatment, but use existing puncture needle can't realize balloon operation, and this programme is due to side opening being arranged on trocar sheath, just can make side opening aim at the fracture direction and make a call to the straight-through fracture of a passage with the software bone drill, then just can implement balloon operation.This shows, the present invention compared with prior art has outstanding substantive distinguishing features and significant progressive, and the beneficial effect of its enforcement is also apparent.
Description of drawings
Fig. 1 is the part sectional structure schematic diagram of the specific embodiment of the invention.
Fig. 2 is that the structure for amplifying schematic diagram is looked up by the A section of Fig. 1.
In figure, 1 is puncture sword head, and 2 is side opening, and 3 is nook closing member, and 4 is trocar sheath, and 5 is the trocar sheath handle, and 6 is the nook closing member handle, and 7 is spigot surface.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by a specific embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
Can find out by accompanying drawing, the vertebral body of this programme has trocar sheath 4 and trocar sheath handle 5 and interior nook closing member 3 and the nook closing member handle 6 of trocar sheath 4 with puncture needle, this programme is that puncture sword head 1 is arranged on the top of described trocar sheath 4, on the trocar sheath 4 on puncture sword head 1 top, the side opening 2 that communicates with trocar sheath 4 inner chambers is arranged, on the puncture sword head 1 between trocar sheath 4 inwalls corresponding with side opening 2 of side opening 2 limits of described puncture sword head 1, arc guide surface 7 is arranged, this arc guide surface 7 is ellipsoidal surfaces.The top of described nook closing member 3 is ellipsoidal surfaces.
The present invention is not limited in the above-mentioned specific embodiment, and the variation that those of ordinary skills make in essential scope of the present invention, remodeling, interpolation or replacement also should belong to protection scope of the present invention.
Claims (3)
1. vertebral body puncture needle, include nook closing member and nook closing member handle in trocar sheath and trocar sheath handle and trocar sheath, it is characterized in that: puncture sword head is arranged on the top of described trocar sheath, on the trocar sheath on puncture sword head top, the side opening that communicates with the trocar sheath inner chamber is arranged, on the puncture sword head between the outer sleeve inner wall corresponding with side opening of the side opening limit of described puncture sword head, arc guide surface is arranged.
2. puncture needle according to claim 1, it is characterized in that: the top of described nook closing member is ellipsoidal surface.
