Abstract

The invention provides a medical bone screw tightening mechanism. The mechanism comprises a handheld gun handle, a torque head is arranged at the front end of the handheld gun handle and provided with a bolt clamping groove, a torque motor is arranged between the torque head and the handheld gun handle, an adjusting knob is arranged on the torque head, and the torque limit of the torque head is adjusted through the adjusting knob. A medical screw is clamped through the torque head at the front end of the handheld gun handle, and the torque head is driven by the torque motor to rotate so as to tighten the medical screw automatically; the torque limit of the torque head is adjusted through the adjusting knob to prevent the medical screw is too tightened or too unscrewed, and the locking stability of the screw is improved; an anti-shaking device 7 is arranged, so that the use safety is improved.

Description

Medical bone screw tightening mechanism
Technical field
The present invention relates to medical instruments field, more particularly to a kind of Medical bone screw tightening mechanism.
Background technology
At present in the medical field, treatment fracture would generally be fixed using medical screw to steel plate, to ensure steel Plate plays a protective role to fracture site.At present when being fixed to steel plate, typically man-hour manually hand-held torsion is risen to medical spiral shell Silk is tightened manually, operating efficiency it is not high and it is artificial to tighten the time more long, easily occur other situations during tightening, It is unfavorable for the treatment of patient.Therefore, tighten the ineffective problem of medical screw during solution fractures and just seem particularly heavy Want.
The content of the invention
It is an object of the invention to provide a kind of Medical bone screw tightening mechanism, by the torsion head pair of hand-held pikestaff front end Medical screw carries out holding, and drives torsion head to rotate by torsion motor, and then medical screw is tightened automatically, and The torsion limit of torsion head is adjusted by adjusting knob, it is to avoid it is too tight or too loose that medical screw is twisted, when solving fractures Tighten the ineffective problem of medical screw.
The present invention provides a kind of Medical bone screw tightening mechanism, including hand-held pikestaff, and the hand-held pikestaff front end is set There is torsion head, bolt draw-in groove is provided with the torsion head, torsion motor, institute are provided between the torsion head and hand-held pikestaff State and adjustment knob is provided with torsion head, the torsion limit of torsion head is adjusted by adjusting knob.
Further improvement is that:Feeler, the feeler and torsion electricity are provided with the bolt draw-in groove Machine is associated, and feeler senses screw, and control torsion motor is started working afterwards in place.
Further improvement is that:Anti-shake apparatus are provided with the hand-held pikestaff, the anti-shake apparatus are arranged on hand-held gun Between handle and torsion head.
Further improvement is that:Be provided with display device by the adjustment knob, by display device to torsion head most Big torsion is shown.
Further improvement is that:Heat sink is provided with the torsion motor.
The beneficial effects of the invention are as follows:Holding is carried out to medical screw by the torsion head of hand-held pikestaff front end, and is passed through Torsion motor drives torsion head to rotate, and then medical screw is tightened automatically, and adjusts torsion head by adjusting knob The torsion limit, it is to avoid medical screw twist it is too tight or too loose, improve screw locking degree of stability, set anti-shake apparatus 7, carry Safety in utilization high.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Wherein:The hand-held pikestaffs of 1-, 2- torsion heads, 3- bolt draw-in grooves, 4- torsion motors, 5- adjustment knobs, 6- sensing contacts Device, 7- anti-shake apparatus, 8- display devices, 9- heat sinks.
Specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, the embodiment It is only used for explaining the present invention, is not intended to limit the scope of the present invention..
As shown in figure 1, a kind of Medical bone screw tightening mechanism is present embodiments provided, including hand-held pikestaff 1, the hand The front end of armed handle 1 is provided with torsion first 2, and bolt draw-in groove 3, the torsion first 2 and hand-held pikestaff 1 are provided with the torsion first 2 Between be provided with torsion motor 4, be provided with the torsion first 2 adjustment knob 5, by adjust knob 5 adjust torsion first 2 torsion The power limit.Feeler 6 is provided with the bolt draw-in groove 3, the feeler 6 is associated with torsion motor 4, contact Sensor 6 senses screw, and control torsion motor 4 is started working afterwards in place.Anti-shake apparatus 7 are provided with the hand-held pikestaff 1, The anti-shake apparatus 7 are arranged between hand-held pikestaff 1 and torsion first 2.Display device 8 is provided with by the adjustment knob 5, is passed through The acrotorque of display device 8 first to torsion 2 shows.Heat sink 9 is provided with the torsion motor 4.By hand-held The torsion first 2 of the front end of pikestaff 1 carries out holding to medical screw, and drives torsion first 2 to rotate by torsion motor 4, and then automatically Medical screw is tightened, and the torsion limit of torsion first 2 is adjusted by adjusting knob 5, it is to avoid medical screw is twisted too It is tight or too loose, the degree of stability of screw locking is improved, anti-shake apparatus 7 are set, improve safety in utilization.
