In figure: steel plate 1, combined hole 2, kink 21, indicate positioner 3, Electromagnetic Vibrator 31, housing 311, vibration cavity 312, shake block 313, solenoid 314, silicon steel core 315, base band 32, without resistance part 33, barb 34, wire 35, supply unit 36, boss 37.
Detailed description of the invention
In Fig. 1 ~ 7, a kind of orthopedic steel plate vibrating location, instruction positioner 3 it is movably installed with on steel plate 1, in instruction positioner 3, in instruction positioner 3, being provided with multiple Electromagnetic Vibrator 31 in base band 32, Electromagnetic Vibrator 31 is corresponding with the position of combined hole 2, preferably, the both sides of base band 32 are provided with metallic framework provides support to keep intensity and elasticity.Use this structure, it is simple to during bone surgery, the vibration utilizing Electromagnetic Vibrator 31 to produce, it is accurately positioned the position of combined hole 2, it is simple to follow-up opening and the operation of installation steel nail.
Preferably as in Fig. 1 ~ 3 in scheme, position corresponding with combined hole 2 in base band 32 is provided with boss 37, Electromagnetic Vibrator 31 it is provided with in boss 37, Electromagnetic Vibrator 31 is connected with wire 35, is provided with barb 34 at least side of boss 37, such as, be positioned at front side, when putting into orthopedic steel plate, barb 34 is for catching on the kink 21 of combined hole 2, and when taking out, pulls base band 32 that barb 34 can be made to depart from kink 21.Preferably, being provided with barb 34 in the both sides of boss 37, barb 34 is for catching on the kink 21 of combined hole 2.Thus structure, it is simple to indicate the installation of positioner 3 and take off.The generally structure of combined hole 2, for having the figure of eight hole of a kink 21, barb 34 is just stuck in the position of kink 21, so that base band 32 is reliably connected with steel plate 1, does not comes off during feeding is subcutaneous.Base band 32 in this example preferably employs medical silica-gel, preferably employs cure process in the position of boss 37.
In optional scheme, described boss 37 is positioned at the top of base band 32, is equipped with barb 34 around boss 37.In order to more preferably fit with skeleton, generally having the arc of indent in the bottom transverse cross section of part steel plate 1, base band 32 can be positioned at arc, during taking out, it is possible to use steel nail, is ejected by boss 37 successively, then whole base band 32 extracted out in combined hole 2.
Another optional scheme, in Fig. 1 ~ 3, described boss 37 is positioned at the lower section of base band 32, is provided with barb 34 in the front side of boss 37 and both sides, and the rear side at boss 37 is provided with without resistance part 33.Thus structure, is arranged on the top of steel plate 1 by base band 32, when behind location, directly whole base band 32 is extracted out, in extraction process, will not stop that boss 37 separates with combined hole 2 without resistance part 33, it is simple to extraction, as shown in Figure 3.
Described is vertical, cambered surface or ramp structure without resistance part 33.
Wire 35 is connected with supply unit 36.Described supply unit 36 is for providing the supply unit of alternating current.Supply unit 36 can be located at the afterbody of base band 32, according to the difference of plate size, it is also possible to is arranged on any positions such as middle part, when being positioned at afterbody, and can be beyond the position of steel plate 1 termination.Thus structure, in addition to being easy to power supply, also allows for when extraction for grasping.Alternating current described in this example, including sine-wave current or the electric current of interval break-make mode.Being used as DC source coordinates direct current to turn ac equipment offer alternating current.The supply unit that can produce alternating current is commonly used in the prior art, and here is omitted.
Preferably in scheme, described Electromagnetic Vibrator 31 is along combined hole 2 axial vibration.Thus structure, it is simple to doctor can more easily determine vibration position.
Preferably in scheme such as Fig. 7, in described Electromagnetic Vibrator 31, being provided with vibration cavity 312 in housing 311, block 313 activity of shaking is positioned at vibration cavity 312, and the one end in housing 311 is provided with solenoid 314, is provided with soft iron or silicon steel core 315 in solenoid 314.By applying alternating current to solenoid 314, the block 313 that makes to shake produces vibration in vibration cavity 312.
The described block 313 that shakes uses soft magnetic bodies or permanent magnet.When the block 313 that shakes using soft magnetic bodies, solenoid 314 is generally made to be positioned at the top of the block 313 that shakes, after solenoid 314 is energized, the soft magnetic bodies block 313 that shakes is adsorbed to soft iron or silicon steel core 315 under magneticaction, produce and once vibrate, when solenoid 314 power-off, then the soft magnetic bodies block 313 that shakes loses magnetic force and falls.Produce lighter vibration.
When the block that shakes using permanent magnet, solenoid 314 produces sine-shaped alternating current, when the magnetic field of solenoid 314 and the magnetic field of permanent magnet are different, the block that then attracts to shake clashes into soft iron or silicon steel core 315 and produces and once vibrate, when the magnetic field of solenoid 314 and the magnetic field of permanent magnet are identical, then repel the block shock housing 311 that shakes and produce another vibration, move in circles, then produce and continuously vibrate.
During use, comprise the following steps:
One, steel plate 1 is placed in a predetermined position from the opening of skin；
Two, the Electromagnetic Vibrator 31 of instruction positioner 3 is opened；
Three, according to the instruction of Electromagnetic Vibrator 31, position corresponding with Electromagnetic Vibrator 31 on skin makes a mark, with the position in positioning combination hole 2；
Four, instruction positioner 3 is taken out；According to the difference of instruction positioner 3 installation site, it is divided into and taking out above steel plate 1, and take out below steel plate；
As shown in Figure 3, when taking out from top, carry out in skin upper shed after instruction positioner 3 can be taken out again, hole and load the operation of steel nail.The program is mainly used in the straight steel plate in common steel plate 1, such as in Fig. 4.
When taking out from below, then need first in skin upper shed, with steel nail by boss 37 after combined hole 2 ejects, then instruction positioner 3 is extracted out, carries out holing and loading the operation of steel nail the most again.The program is mainly used in the steel plate that shape is complex, such as Fig. 5, steel plate in 6.Fig. 5, steel plate in 6 are more complicated 3D shape, in steel plate insertion process, therefore, to assure that the connection between instruction positioner 3 and steel plate is reliable, difficult drop-off.
Pass through above step, it is achieved being accurately positioned of combined hole 2 position.
The above embodiments are only the preferred technical solution of the present invention, and are not construed as the restriction for the present invention, and on the premise of not conflicting mutually, every technical characteristic that the present invention records can be combined with each other.The technical scheme that protection scope of the present invention should be recorded with claim, is protection domain including the equivalents of technical characteristic in the technical scheme that claim is recorded.Equivalent the most in this range is improved, also within protection scope of the present invention.
