Abstract
The utility model relates to a medicinal manual and electrically driven dual-purpose bone penetrating needle, which is used for bone sampling biopsy by skin puncture. The utility model is characterized in that an end circular ring which is arranged on one end of a sleeve pipe (1) is provided with saw teeth (5) (6), the cutting side of the sleeve pipe (1) is provided with an inclined plane (7), and the other end of the sleeve pipe (1) is provided with a holding handle (2) which is 2 to 3 cm away from a port (9). A needle core (4) is matched with the sleeve pipe (1), the needle core (4) is arranged in the sleeve pipe (1) from the port (9), the inlet end (8) of the needle core (4) forms a pyramid shape, the top of the needle core (4) is exposed outside the sleeve pipe (1), and the other end of the needle core (4) is provided with a holding handle (3). The utility model has the advantages of reasonable design, simple structure, convenient operation, large sampling example, light compression, high diagnosis coincidence rate, high safety, time saving, labor saving and high work efficiency.
Description
This utility model relates to the instrument field that the medical science human body takes out medium, is specifically related to a kind of hands behaviour, electric dual-purpose medullo-puncture needle.
In the prior art of body bone tissue biopsy, multiple sampler is arranged, limit to but these device specimen tissue mass of getting are little, or big because of bone sample surface with the frictional force of internal surface of sleeve pipe, compression is serious, and influences the coincidence rate of pathological diagnosis.Chinese patent ZL92211502.8, name is called " low-frictional force bone aspiration biopsy pin ", go up the genus device bigger progress is arranged, though it has large and complete of institute's specimen volume of getting, the advantage that the tissue extruding is lighter, but still deposit following shortcoming: the one, because the bone that sleeve pipe produces when drilling through osseous tissue bits, part is clamp-oned the volume that has increased sleeve pipe inner tissue in the sleeve pipe, extruding to getting specimen tissue still can not drop to minimum level, and the diagnosis of pathology is still had certain influence; The 2nd, this biopsy needle can only be operated by hand, and it is time-consuming to require great effort, inefficiency.
The purpose of this utility model is the shortcoming that overcomes above-mentioned " low-frictional force bone aspiration biopsy pin ", provides a kind of reasonable in design, novel structure, simple, slight to the extruding of getting specimen tissue, the diagnostic accordance rate height, but and not only hand-holdable operation but also electric operating, the dual-purpose medullo-puncture needle in laborsaving timesaving.
The technical solution of the utility model is to realize by the improvement design that sawtooth inclined design and other end handle to sleeve pipe (1) one end are provided with.Its major technique feature is to be provided with sawtooth (5), (6) on the end annulus of sleeve pipe (1) one end, truncated sides is provided with an inclined-plane (7) on it, the other end is provided with handle (2) apart from 2～3 centimeters of sleeve pipe (1) port (9), nook closing member (4) matches with sleeve pipe (1), install in it from the port (9) of sleeve pipe (1), its inlet side portion (8) is a pyramid-shaped, and its top is prismatic and is exposed to outside the sleeve pipe (1), and the other end is provided with handle (3).
Its technical characterictic be the sawtooth (5), (6) on its sleeve pipe (1) one end annulus go up truncated sides inclined-plane (7) by foreign side is to setting backward in preceding, its inclined-plane is 45 degree.
The utility model has the advantages that: since the sawtooth of its sleeve pipe one end on the truncated sides inclined-plane design by in preceding backward foreign side to setting, the bone bits that produce during cutting slide towards periphery along its inclined-plane and do not enter sleeve pipe, the extruding that the specimen tissue of getting is subjected to drops to bottom line, through clinical practice 53 examples, the former state that has all kept the histiocyte form, make pathological diagnosis clearer and more definite, improved diagnostic accordance rate; The handle of its sleeve pipe other end is apart from (9) 2～3 centimetres of sleeve ports, and the electricity consumption drill point is lived its end operation, laborsaving saving time, high efficiency, available again hand-held handle (2) operation.Easy to use, safe and reliable.
Description of drawings:
Fig. 1 is the novel structural front view of this use
Fig. 2 is that the A of Fig. 1 is to view
Fig. 3 is that the B of Fig. 2 is to expanded view
Fig. 4 is the C-C cutaway view of Fig. 3
The embodiment that provides in conjunction with the accompanying drawings describes this utility model in detail.
With reference to figure 1, Fig. 2, this utility model is by sleeve pipe (1), port (9), and sawtooth (5), (6), inclined-plane (7), and nook closing member (4), handle (3) and syringe needle (8) are formed.One end distance port (9) 2～3 centimeters of present embodiment middle sleeve (1) are provided with handle (2), the annulus of the other end is provided with the sawtooth (5) of band gradient, (6), tilt in the direction of the clock, its sawtooth (5), (6) in a teeth directional, dial 0.2mm as shown in Figure 2, sawtooth (5), (6) go up the inclined-plane (7) of truncated sides as Fig. 2, Fig. 3, shown in Figure 4, by direction setting outer backward in preceding, its gradient is 45 degree, around the chip that produces when guaranteeing that it drills through osseous tissue slides to along its inclined-plane (7) and do not enter tube chamber, the extruding that the tissue of getting is subjected to is reduced to minimum level; Present embodiment middle sleeve (1), nook closing member (4) are made with rustless steel, respectively with sleeve pipe (1), nook closing member (4) welding, the port (9) of sleeve pipe (1) is located to join with electric drill with argon arc welding for its handle (2), (3), but electric operating, laborsaving saving time, high efficiency.It is reasonable in design, and is simple in structure, easy to manufacture, and operation and easy to maintenance is suitable for hospitals at different levels and popularizes.
Claims (3)
1, a kind of hands behaviour of containing sleeve pipe, nook closing member, sawtooth, handle, the electric dual-purpose medullo-puncture needle, the end annulus that it is characterized in that sleeve pipe (1) one end is provided with sawtooth (5), (6), truncated sides is provided with inclined-plane (7) on it, and the other end is provided with handle (2) apart from 2～3 centimeters of sleeve pipe (1) port (9); Nook closing member (4) matches with sleeve pipe (1), installs in it from the port (9) of sleeve pipe (1), and the inlet side portion (8) of nook closing member (4) is pyramid-shaped, and its top is prismatic and is exposed to outside the sleeve pipe (1), and the other end is provided with handle (3).
