Abstract
A fixing stringing needle for the orthopedics department comprises a drill stem (1), a sleeve cap (3) and a lining rod (2). One end of the drill stem (1) is a drill bit portion (11), and the other end of the drill stem (1) is a fixing portion (12). The sleeve cap (3) is arranged on the drill bit portion (11) and connected with the drill stem (1) in a sleeved mode. The lining rod (2) is arranged on the fixing portion (12) and connected with the drill stem (1) in an inserting mode. Blind holes (13) are formed in the outer side surface of the drill stem (1). The drill stem (1) fixes broken bones, the lining rod (2) and the sleeve cap (3) protect the drilling portion, the blind holes (13) absorb the bone marrow, the drill stem is not used as a fixing stringing nail any more, and therefore discomfort of patients is avoided.

Three, summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of this utility model is to provide a kind of fixing string pin for orthopaedics, has therefore avoided the uncomfortable phenomenon of patient to occur.
For achieving the above object, the technical scheme that this utility model is taked is: drilling rod that to include position, one end and be drill bit position other end position be fixed position, be arranged on the cap bag that connects on drill bit position and with drilling rod sleeve type, be arranged on the lining bar connecting on fixed position and with drilling rod plug-in type, on the lateral surface of drilling rod, be provided with blind hole.
Lining bar and cap bag are taken out from drilling rod; on the blind hole cavity of drilling rod, connect with electric hand drill; start electric hand drill, drilling rod is driven in the skeleton fractureing, and then lining bar and cap bag are inserted in drilling rod; owing to having designed drilling rod, lining bar and cap bag; the skeleton fixedly fractureing by drilling rod, by lining bar and cap bag protection boring sites in curing, absorbs bone marrow by blind hole; do not re-use drilling rod as fixing string nail, therefore avoided the uncomfortable phenomenon of patient to occur.
This utility model has designed, and is provided with blind hole cavity and serves as a contrast in the blind hole cavity that bar is arranged on drilling rod in drilling rod, and lining bar is set to connect with drilling rod plug-in type, and cap bag is arranged on the drill bit position of drilling rod and connects with drilling rod sleeve type.
This utility model has designed, be set to drill bit position at the position, one end of drilling rod and other end position is set to fixed position, drill bit position is set to cuboid and on drill bit position, is provided with the blade distributing by helix, and fixed position is set to bullet and bevel angle is set to 5-11 °.
This utility model has designed, and on the blind cavity body wall of drilling rod, is provided with spline, on the lateral surface of lining bar, is provided with spline flange.
This utility model has designed, and on the outer end end face of lining bar and cap bag, is provided with step surface.
This utility model has designed, and fixed position 12 is set to bullet and bevel angle is set to 7.2 °.In the technical program, due to the effect of bevel angle, its fixed effect is best.
In the technical program, drilling rod 1, lining bar 2 and cap bag 3 are important technical characterictic, in the technical field of the fixing string pin for orthopaedics, have novelty, creativeness and practicality.
Four, brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Five, detailed description of the invention
Fig. 1 is first embodiment of the present utility model, illustrate by reference to the accompanying drawings the present embodiment, include drilling rod 1, lining bar 2 and cap bag 3, in drilling rod 1, be provided with blind hole cavity and serve as a contrast in the blind hole cavity that bar 2 is arranged on drilling rod 1, lining bar 2 is set to connect with drilling rod 1 plug-in type, cap bag 3 is arranged on the drill bit position 11 of drilling rod 1 and connects with drilling rod 1 sleeve type, is provided with blind hole 13 on the lateral surface of drilling rod 1.
In the present embodiment, be set to drill bit position 11 other end position at the position, one end of drilling rod 1 and be set to fixed position 12, drill bit position 11 is set to cuboid and on drill bit position 11, is provided with the blade distributing by helix, and fixed position 12 is set to bullet and bevel angle is set to 5 °.
In the present embodiment, on the blind cavity body wall of drilling rod 1, be provided with spline, on the lateral surface of lining bar 2, be provided with spline flange.
In the present embodiment, on the outer end end face of lining bar 2 and cap bag 3, be provided with step surface.
Lining bar 2 and cap bag 3 are taken out from drilling rod 1, on the blind hole cavity of drilling rod 1, connect with electric hand drill, start electric hand drill, drilling rod 1 is driven in the skeleton fractureing, and then lining bar 2 and cap bag 3 are inserted in drilling rod 1.
Second embodiment of the present utility model, fixed position 12 is set to bullet and bevel angle is set to 11 °.
The 3rd embodiment of the present utility model, fixed position 12 is set to bullet and bevel angle is set to 8 °.
The 4th embodiment of the present utility model, fixed position 12 is set to bullet and bevel angle is set to 7.2 °.In this utility model, by test, the pulling force that the drilling rod 1 that diameter is 15mm bears is 2.5N.
The utlity model has lower feature:
1, owing to having designed drilling rod 1, lining bar 2 and cap bag 3; the skeleton fixedly fractureing by drilling rod 1, protects boring sites in curing by lining bar 2 and cap bag 3, absorbs bone marrow by blind hole 13; do not re-use drilling rod as fixing string nail, therefore avoided the uncomfortable phenomenon of patient to occur.
