Abstract
The utility model discloses a kind of bone to sample trepan, it is related to medical instruments field, including trepan main body, connecting portion and trepan bar, trepan bar is configured as connection electricity turn or gripping handle, connecting portion is configured as connection ring drilling rod and trepan main body, the end set of trepan main body has trepan tooth and groove, and groove vertical runs through the end both sides of trepan main body in the plane where trepan tooth.Trepan bar is polygon or has external screw thread.Connecting portion is hollow or solid.The end set of trepan main body has window.The internal diameter of trepan main body is 5 10mm.The width of groove is 0.5 2mm.Trench length is 5 15mm.When sampling end needs to take out sclerotin, taken out after clamping bone sample along side grooves 3 with tweezers, or a Kirschner wire is run through into bone sample from side grooves 3, then held Kirschner wire both ends, sclerotin is completely extracted.
Description
Technical field
It the utility model is related to medical instruments field, more particularly to a kind of bone sampling trepan.
Background technology
In order to assess bone mass or osseous lesion, or autologous bone bone collection is taken, generally require to be taken out bone with trepan.Common ring
Drilling through out the principle of sclerotin is：Trepan is close to sclerotin, forward 1-5 centimetres of rotary drilling sclerotin, now, one is contained in trepan
The cylindrical sclerotin of section, now quickly extracts trepan, can typically pull off cylindrical sclerotin distal end, so as to take out sclerotin.Take out
After sclerotin, sclerotin can be taken out with vessel forceps or Kirschner wire.Typically, since sclerotin is close to trepan inwall, often from
Sclerotin goes wrong when trepan takes out bone sample, violence taking-up often occurs, destroys the situation of sclerotin.
Therefore, those skilled in the art is directed to developing a kind of bone sampling trepan, ideally can be taken out from trepan
Bone sample, accurately to analyze bone mass or osseous lesion.
Utility model content
In view of the drawbacks described above of prior art, technical problem to be solved in the utility model is how to design a kind of bone
Trepan is sampled, bone sample can be easily removed.
To achieve the above object, the utility model provides a kind of bone sampling trepan, including trepan main body, connecting portion and ring
Drilling rod, the trepan bar are configured as connection electricity and turned or gripping handle, the connecting portion be configured as connecting the trepan bar and
The trepan main body, the end set of the trepan main body have trepan tooth and groove, and the groove vertical is in the trepan tooth institute
Plane, and through the trepan main body end both sides.
Further, the trepan bar is polygon or has external screw thread.
Further, the connecting portion is hollow or solid.
Further, the end set of the trepan main body has window.
Further, the internal diameter of the trepan main body is 5-10mm.
Further, the width of the groove is 0.5-2mm.
Further, the trench length is 5-15mm.
Bone sampling trepan described in the utility model includes upper and lower two parts, is tubular structure, upper and lower two parts UNICOM,
Top is trepan bar, can be hollow or solid.Upper end outer wall can be polygon, for the firm electric drill of card, or with spiral shell
The circle of line, matched handle can be screwed into.
Lower diameter is more than top, is trepan main body, its distalmost end has trepan tooth, for screwing in sclerotin.Trepan main body is just
There is windowing in face, while there are groove, 0.5~2mm of ditch groove width in both sides.
When sampling end needs to take out sclerotin, taken out after clamping bone sample along side grooves with tweezers, or by one piece gram
Family name's pin runs through bone sample from side grooves, then holds Kirschner wire both ends, sclerotin is completely extracted.
Design, concrete structure and caused technique effect of the present utility model are made furtherly below with reference to accompanying drawing
It is bright, to be fully understood from the purpose of this utility model, feature and effect.
Brief description of the drawings
Fig. 1 is the bone sampling trepan of a preferred embodiment of the present utility model.
Embodiment
As shown in figure 1, bone sampling trepan described in the utility model includes upper and lower two parts, it is tubular structure, up and down
Two parts UNICOM, top are trepan bar 1 and connecting rod 2, can be hollow or solid.Upper end outer wall can be polygon, use
In the firm electric drill of card, or threaded circle, matched handle can be screwed into.
Lower diameter is more than top, is trepan main body 5, its distalmost end has trepan tooth 4, for screwing in sclerotin.Trepan main body
There is windowing in front, while there are groove 3,3 wide 0.5~2mm of groove in both sides.
When sampling end needs to take out sclerotin, a Kirschner wire is run through into bone sample from side grooves 3, then holding gram
Family name's pin both ends, sclerotin is completely extracted.
Preferred embodiment of the present utility model described in detail above.It should be appreciated that the ordinary skill of this area without
Creative work can is needed to make many modifications and variations according to design of the present utility model.Therefore, it is all in the art
Technical staff on the basis of existing technology can by logical analysis, reasoning, or a limited experiment according to design of the present utility model
, all should be in the protection domain being defined in the patent claims with obtained technical scheme.
