Background technology
Bone cement has another name called bone cement, is a kind of medical material for bone surgery, and it is mainly used in prosthetic replacement's operation.For the ease of storage and transport, bone cement is made up of white powder and colourless liquid two parts preparation with penetrating odor.When use, as long as by a certain percentage, they are poured on together and are in harmonious proportion, at room temperature polymerization reaction take place.Bone cement only has tens minutes from starting to be aggregated to curing whole process, and therefore doctor, before bone cement sclerosis, is placed to by it the position of preparing to change joint, sets up immediately artificial joint.
At present, orthopedist is widely used traditional hand gun and comes for patient injection bone cement, this injection system, there will be following deficiency: first, because only have tens minutes the hardening time of bone cement, therefore along with the carrying out of injection, bone cement hardening and make to inject the increasing of strength gradually; Although adopt the mode of fast injection can ensure that bone cement is injected in patient body before solidifying, manually fast injection Chang Yin is difficult to control and to cause bone cement to fill excessive, causes complication, needs operation to solve, and then causes serious consequence; Therefore need experienced doctor to rely on its experience to judge the hardenability of bone cement, to ensure that bone cement can be injected in patient body before solidifying, if not injected and bone cement hardening in when operation, often appears in the doctor who lacks experience, phenomenon that have to Halfway Stopping.Secondly,, because injection bone cement must show in real time by X-ray, therefore medical worker and can being simultaneously exposed under X-ray irradiates with patient, can cause medical personnel's professional ionizing radiation to expose to the open air, brings out cancer.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of bone cement automated injection device, and it can control effectively to the speed in bone cement injection process and pressure, avoids anthropic factor to judge bone cement injection process adverse effect.
For addressing the above problem, a kind of bone cement automated injection device that this utility model is designed, includes high-pressure injection cylinder, and the rear portion of this high-pressure injection cylinder is provided with pushing ram, and the front end of high-pressure injection cylinder is provided with entry needle; Its difference is also to include power supply, control circuit board and the motor with locking device; Power supply is connected with control circuit board, and the input of control circuit board is provided with control button, and the outfan of control circuit board connects the control end of motor.Motor with locking device can make injection volume and injection force accurately controlled, and in the time that the pressure of bone cement exceeds the setting pressure limit, motor can be automatically locked.
Described control button is arranged on a control panel, and this control panel is connected with control circuit board through control signal wire.
In order can intuitively to show the injection rate of bone cement, control panel is provided with injection volume display screen, and this injection volume display screen is connected with control circuit board through the control signal wire of control panel.
In order can intuitively to show the injection pressure of bone cement, this utility model also further includes a pressure transducer, and this pressure transducer is arranged on the front end of pushing ram, and the outfan of pressure transducer is connected with the input of control circuit board; Now, control panel is provided with pressure display screen, and this pressure display screen is connected with control circuit board through the control signal wire of control panel.
In order to ensure health, described high-pressure injection cylinder is removable disposable high-pressure injection cylinder.
Compared with prior art, the utlity model has following features:
1, the push-in stroke and the propulsive force that adopt step motor control high-pressure injection cylinder, make bone cement injection volume and injection force can realize accurate control, effectively avoids artificially judging bone cement injection process adverse effect;
2, adopt line traffic control mode to realize the control of motor work process, can avoid under doctor's irradiation in X-ray for a long time;
3, can intuitively show the state of injection process by injection volume display screen and pressure display screen, be conducive to doctor injection process is controlled in real time.
