Abstract
The utility model provides a puncture needle for a vertebral body. The puncture needle has the technical scheme that that the puncture needle comprises an outer sleeve, an outer sleeve handle, a needle core and a needle core handle, wherein the needle core is arranged in the outer sleeve. The puncture needle is characterized in that a puncture blade head is arranged on the top end of the outer sleeve, a side opening communicated with an inner cavity of the outer sleeve is formed in the outer sleeve on the upper part of the puncture blade head, and a cambered guide surface is formed on the puncture blade head between the side opening edge of the puncture blade head and the inner wall of the outer sleeve, which corresponds to the side opening. The puncture needle is further characterized in that the top end of the needle core is an ellipsoidal surface, and the cambered guide surface on the puncture blade head is an ellipsoidal surface.
Description
Technical field
The utility model relates to 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 usefulness, and conventional vertebral body puncture needle all is 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 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 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 in prior technology weak point.
Summary of the invention
Technical problem to be solved in the utility model, be exactly at the existing in prior technology deficiency, and provide a kind of vertebral body puncture needle technical scheme, this scheme employing has puncture sword head on the top of trocar sheath, trocar sheath on puncture sword head top has side opening, utilize side opening to select the most approaching position of operation that needs to undergo surgery, and nook closing member just play the effect of strengthening trocar sheath intensity when puncture.
This programme is realized by following technical measures: vertebral body includes nook closing member and nook closing member handle in trocar sheath and trocar sheath handle and the trocar sheath with puncture needle, the characteristics of this programme are that puncture sword head is arranged on the top of described trocar sheath, trocar sheath on puncture sword head top has the side opening that communicates with the trocar sheath inner chamber, and the puncture sword head between the outer sleeve inner wall corresponding with side opening of the side opening limit of described puncture sword head has arc guide surface.The concrete characteristics of this programme also have, and the top of described nook closing member is ellipsoidal surface.Arc guide surface on the described puncture sword head is ellipsoidal surface.
The beneficial effect of this programme can be learnt according to the narration to such scheme, owing to be that puncture sword head is arranged on the top of trocar sheath in this scheme, trocar sheath on puncture sword head top has the side opening that communicates with the trocar sheath inner chamber, and the puncture sword head between the outer sleeve inner wall corresponding with side opening of the side opening limit of described puncture sword head has arc guide surface.This structure, the function of puncture are to be reached by the puncture sword head on the trocar sheath, and therefore, puncture is to be finished 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 that undergos surgery 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 carry out the sacculus operative treatment, but be to use existing puncture needle can't realize the sacculus operation, and this programme is owing to have side opening at 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, just can implement the sacculus operation then.This shows that this utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is apparent.
Description of drawings
Fig. 1 is the part sectional structure sketch map of this utility model specific embodiment.
Fig. 2 looks up the structure for amplifying sketch map for the A portion of Fig. 1.
Among the 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.
By accompanying drawing as can be seen, the vertebral body of this programme has nook closing member 3 and nook closing member handle 6 in trocar sheath 4 and trocar sheath handle 5 and the trocar sheath 4 with puncture needle, this programme is that puncture sword head 1 is arranged on the top of described trocar sheath 4, trocar sheath 4 on puncture sword head 1 top has the side opening 2 that communicates with trocar sheath 4 inner chambers, puncture sword head 1 between corresponding trocar sheath 4 inwalls of side opening 2 limits of described puncture sword head 1 and side opening 2 has arc guide surface 7, and this arc guide surface 7 is ellipsoidal surfaces.The top of described nook closing member 3 is ellipsoidal surfaces.
Claims (3)
1. vertebral body puncture needle, include nook closing member and nook closing member handle in trocar sheath and trocar sheath handle and the trocar sheath, it is characterized in that: puncture sword head is arranged on the top of described trocar sheath, trocar sheath on puncture sword head top has the side opening that communicates with the trocar sheath inner chamber, and the puncture sword head between the outer sleeve inner wall corresponding with side opening of the side opening limit of described puncture sword head has arc guide surface.
