Described plow-shape sword face can be according to shallow after dark before its turn direction, deep tread can be that 1.9 ~ 2.1mm, height can be 0.9 ~ 2.1mm, superficial part tread can be that 0.2 ~ 1.1mm, height can be 0.2 ~ 0.4mm, sword face length can be 2.0 ~ 2.5mm, from deep to superficial part, be progressively bent inwardly to plow-shape also according to the progressively transition of angle of its turn direction front end cutting edge inclined-plane and sleeve pipe longitudinal axis, deep sword face can become 60 ~ 80 degree angles with push rod longitudinal axis.
The front end of described plow-shape sword face can have at least three sharp sword teeth.
The front end point sword tooth of described circular arc sword face and the front end tooth depth of described plow-shape sword face can be 0.5 ~ 1mm, can be triangle or circular arc.
Described sleeve pipe external diameter is that 3.6 ~ 5.8mm, internal diameter are 2.8 ~ 5.0mm.
The front end of described plow-shape sword face can also have at least three sharp sword teeth.
In face of described circular arc sword, holding the front end point sword tooth tooth depth of sharp sword tooth and plow-shape sword face can be 0.5 ~ 1mm, aobvious triangle or circular arc.
Further: can also comprise stop, described stop is arranged in push rod and pushes away between handle and sleeve pipe lever, is placed on push rod.
Described plow-shape sword face is key of the present utility model, and the plow-shape knife edge that it has cuts and organizes and makes to organize along screw inclined plane and advances in sleeve pipe in precession process.To drawing materials, the turn of terminal original place can be from disconnected end 66.7% ~ 88.9%.(R
2-r
2/ R
2) tissue, the tissue of taking-up interconnects, and simultaneously has again plow-shape structure to stop to avoid drawing materials to organize rollback.Greatly improve the success rate of drawing materials.Increase the definite degree of drawing materials.
Further, this utility model can also comprise stop, and its size can be amplified as required in proportion.Described stop can be arranged in push rod and push away between handle and sleeve pipe lever, is placed on push rod.Can effectively control and inject length like this, prevent from injecting and excessively cause damage.
This utility model can also be used as bone cement tucker,, can reach the object of multi-use.Implementation process can be used the former bone cement tucker technological process of production to produce, practical, excellent
The beneficial effects of the utility model are: can effectively control and improve tissue sampling amount and the success rate of drawing materials, test the success rate 100% of drawing materials.And can reach and be both easy to turn incision, be not easy again the perverse vertebral body of wearing.And can effectively control the length of drawing materials.Reduce the damage of puncture, greatly improve the success rate of drawing materials and reduce wound, once draw materials successfully, improve diagnosis promptness, accuracy.
