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 be used orthopedic steel plate in the time for the treatment of fracture patient, utilizes orthopedic steel plate that patient's knochenbruch is fixed.Because recovery time is long, during bone healing, patient can move, simultaneously for fear of amyotrophy, appropriate motion has facilitation for patient's recovery, but patient's activity can cause steel plate, over-burden or cause steel plate fatigability fracture owing to moving frequently, although doctor can enjoin patient not to be engaged in strenuous exercise and movable too frequently, owing to there is no quantitative index and checkout gear, patient is difficult to grasp suitable quantity of motion.In the time that 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 conventionally, is easy to occur overbending or fractures because of mechanical fatigue.
Summary of the invention
The object of this invention is to provide a kind of orthopedic steel plate simple in structure, easy to use, when steel plate bending is excessive, can point out to patient, thereby avoid steel plate because of stressed excessive fracture.
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, trigger switch is installed on described steel plate body, coordinates frizzen, the drive circuit being electrically connected with trigger switch, the vibrator that is connected to drive circuit outfan and the electronic syringe pump installed with trigger switch.
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 frizzen perpendicular to steel plate body, and the top of described frizzen is provided with the bulb being arranged in ball-and-socket.
Described frizzen is strip cylinder, steel plate body is provided with strip groove, described strip groove is along the length direction setting of steel plate body, and frizzen is inlaid in described strip groove, and described trigger switch is arranged between frizzen and the inwall of described strip groove.
Adopt after technique scheme, this orthopedic steel plate is simple in structure, easy to use, and being provided with to be beneficial to of frizzen disperses steel plate stressed, improves bending voltage endurance capability.In addition, when steel plate bending is excessive, alarm device can be pointed out to patient, thereby avoids steel plate because of stressed excessive fracture, is conducive to reduce the generation of doctor-patient dispute.

The specific embodiment
As shown in Figure 1, orthopedic steel plate with prompt functions of the present invention comprises steel plate body 1, trigger switch 2 is installed on described steel plate body 1, coordinates frizzen 3, the drive circuit 4 being electrically connected with trigger switch 2, the vibrator 5 that is connected to drive circuit 4 outfans and the electronic syringe pump 6 installed with trigger switch 2.The input of electronic syringe pump 6 is connected to pain liquid reservoir by check valve, the injection that makes people produce pain is housed in pain liquid reservoir, the outfan of electronic syringe pump 6 connects the syringe of implant into body, when moving, electronic syringe pump 6 injection in pain liquid reservoir can be injected to human body, make people produce pain, remind patient.The effect of drive circuit 4 is the signals that receive trigger switch 2, and in the time receiving the actuating signal of trigger switch 2, drive vibrator 5 and electronic syringe pump 6 to move, described drive circuit 4, vibrator 5 and electronic 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, has in the situation of multiple ball-and-sockets or multiple trigger switches, can by multiple trigger switches with or logical structure parallel connection, can cause follow-up action as long as there is a trigger switch 2 to trigger; Described frizzen 3 is fixedly connected on steel plate body 1 by anchor pole 31, and two anchor poles 31 are at least set on frizzen 3, and frizzen 3 is stably set in parallel on steel plate body 1.Frizzen 3 is provided with the frizzen 32 perpendicular to steel plate body 1, and the top of described frizzen 32 is provided with the bulb 33 being arranged in ball-and-socket.Under steel plate body 1 keeps straight normal condition, bulb 33 is positioned at the middle of ball-and-socket, can not oppress trigger switch 2.In the time of the 1 stressed bending of steel plate body, must break the parallel relation between steel plate body 1 and frizzen 3, touch one of them trigger switch 2, the signal that trigger switch 2 produces is controlled vibrator 5 and electronic syringe pump 6 moves through drive circuit 4, the pain that the injection that the vibrations that vibrator 5 produces and electronic syringe pump 6 inject 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 rectangle plate-like 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 the spherical or hemispherical matching.
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 along the length direction setting of steel plate body 1, frizzen 3 is inlaid in described strip groove, and described trigger switch 2 is arranged between frizzen 3 and the inwall of 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.
