With the orthopedic steel plate of prompt functions
Technical field
The present invention relates to a kind of medical apparatus and instruments, is a kind of orthopedic steel plate with prompt functions specifically.
Background technology
Modern medicine often will use orthopedic steel plate when treating fracture patient, utilizes orthopedic steel plate to be fixed by the knochenbruch of patient.Because recovery time is long, during bone healing, patient can move, simultaneously in order to avoid amyotrophy, appropriate motion has facilitation for the recovery of patient, but the activity of patient can cause steel plate, and over-burden or cause steel plate fatigability to rupture owing to moving frequently, although doctor can enjoin patient not to be engaged in strenuous exercise and activity too frequently, owing to not having quantitative index and checkout gear, patient is difficult to grasp suitable quantity of motion.When quantity of motion exceedes the ability to bear of steel plate, steel plate will rupture, and causes extra injury to patient.When the stressed bending of this steel plate, bending part concentrates on a bit usually, is easy to overbending occurs or fractures because of mechanical fatigue.
Summary of the invention
The object of this invention is to provide the orthopedic steel plate that a kind of structure is simple, easy to use, can point out to patient when steel plate bending is excessive, thus avoid steel plate because of stressed excessive and rupture.
For achieving the above object, the present invention adopts following technical scheme:
Orthopedic steel plate with prompt functions of the present invention comprises steel plate body, vibrator and the motorised syringe pump of the drive circuit outfan that described steel plate body is provided with trigger switch, coordinates the frizzen installed, the drive circuit be electrically connected with trigger switch with trigger switch, is connected to.
Described steel plate body is provided with ball-and-socket, and trigger switch is arranged on the inwall of described ball-and-socket; Described frizzen is fixedly connected on steel plate body by anchor pole, and frizzen is provided with the touch pole perpendicular to steel plate body, and the top of described touch pole is provided with the bulb be arranged in ball-and-socket.
Described frizzen is strip cylinder, steel plate body is provided with strip groove, described strip groove is arranged along the length direction of steel plate body, and frizzen is inlaid in described strip groove, and described trigger switch is arranged between the inwall of frizzen and described strip groove.
Adopt after technique scheme, this orthopedic steel plate structure is simple, easy to use, and it is stressed that being provided with of frizzen is beneficial to dispersion steel plate, improves bending voltage endurance capability.In addition, when steel plate bending is excessive, alarm device can be pointed out to patient, thus avoids steel plate because of stressed excessive and rupture, and is conducive to the generation reducing doctor-patient dispute.

Detailed description of the invention
As shown in Figure 1, orthopedic steel plate with prompt functions of the present invention comprises steel plate body 1, vibrator 5 and the motorised syringe pump 6 of drive circuit 4 outfan that described steel plate body 1 is provided with trigger switch 2, coordinates the frizzen 3 installed, the drive circuit 4 be electrically connected with trigger switch 2 with trigger switch 2, is connected to.The input of motorised syringe pump 6 is connected to pain liquid reservoir by check valve, in pain liquid reservoir, the injection making people produce pain is housed, the outfan of motorised syringe pump 6 connects the syringe of implant into body, injection in pain liquid reservoir can be injected human body during motorised syringe pump 6 action, make people produce pain, remind patient.The effect of drive circuit 4 is the signals receiving trigger switch 2, and drive vibrator 5 and motorised syringe pump 6 action when receiving the actuating signal of trigger switch 2, described drive circuit 4, vibrator 5 and motorised syringe pump 6 are prior art, do not do more description at this.
As shown in Figure 2 and Figure 3, as one embodiment of the present of invention, described steel plate body 1 is provided with ball-and-socket, trigger switch 2 is arranged on the inwall of described ball-and-socket, trigger switch 2 can adopt microswitch, also can adopt thin film switch, when having multiple ball-and-socket or multiple trigger switch, can by multiple trigger switch with or logical structure in parallel, as long as namely have a trigger switch 2 to trigger can cause follow-up action; Described frizzen 3 is fixedly connected on steel plate body 1 by anchor pole 31, frizzen 3 is at least arranged two anchor poles 31, is stably set in parallel on steel plate body 1 by frizzen 3.Frizzen 3 is provided with the touch pole 32 perpendicular to steel plate body 1, and the top of described touch pole 32 is provided with the bulb 33 be arranged in ball-and-socket.When under the normal condition that steel plate body 1 keeps straight, bulb 33 is positioned at the middle of ball-and-socket, can not oppress trigger switch 2.When steel plate body 1 stressed bending time, the parallel relation between steel plate body 1 and frizzen 3 must be broken, touch one of them trigger switch 2, the signal that trigger switch 2 produces controls vibrator 5 and motorised syringe pump 6 action through drive circuit 4, the vibrations that vibrator 5 produces and the pain that the injection that motorised syringe pump 6 injects produces can remind patient to note the amplitude of moving, and the state of timely medical check steel plate.
Certainly, above-mentioned bulb 33 can be discoid or rectangular disk as shown in Figure 3, and ball-and-socket is the disc that matches or square; Bulb 33 also can adopt spheroid or hemisphere, and ball-and-socket is then the spherical or hemispherical matched.
As shown in Figure 4, Figure 5, as an alternative embodiment of the invention, described frizzen 3 is strip cylinder, steel plate body 1 is provided with strip groove, described strip groove is arranged along the length direction of steel plate body 1, frizzen 3 is inlaid in described strip groove, and described trigger switch 2 is arranged between the inwall of frizzen 3 and described strip groove.This spline structure is compacter, and sensitivity is higher.
The setting of frizzen also helps and disperses steel plate stressed, improves bending voltage endurance capability.
