Abstract
The utility model discloses a vertebral pedicle ultrasonic detecting instrument which comprises a vertebral pedicle drill bit, a computer and a display connected with the computer. The vertebral pedicle drill bit comprises a drill bit body and a handle. At least one micro ultrasonic probe is arranged inside the top end of the drill bit body. The micro ultrasonic probe is connected with an ultrasonic signal gain amplifier. The ultrasonic signal gain amplifier is connected with a signal processor. The signal processor is connected with the computer. On one hand, the vertebral pedicle ultrasonic detecting instrument can avoid damage to spinal nerves, vessels and peripheral visceral organs, on the other hand, repeated puncturing due to blind puncturing is avoided, and holding force and stability of a screw are not influenced, and therefore accuracy and safety of drilling of a vertebral pedicle or arrangement of the screw can be greatly improved.
Description
Technical field
This utility model belongs to a kind of medical apparatus and instruments, particularly a kind of pedicle of vertebral arch supersonic sounding instrument of the pedicle of vertebral arch boring for spinal surgery.
Background technology
The spinal column pedicle of vertebral arch drill bit that uses clinically is simple metal borer at present,
No any detection or navigation feature, when operator carried out the boring of spinal column pedicle of vertebral arch, even deviation also appears in veteran spinal surgeons easily, the lighter was that the duct is incorrect, severe patient Spinal Cord nerve or trunk cause the generation of severe complication.
Therefore, in order to improve accuracy rate and the safety of the boring of spinal column pedicle of vertebral arch, numerous medical personnels and biological engineering are an apprentice of stage construction, multi-angle is explored and study, strengthen that guiding is exactly major progress and the achievement that obtains in recent years with monitoring in the art, and wherein use and report that more method has: the application of the application of somatosensory evoked potential and Motion Evoked Potential, electromagnetic field in the art, monoplane X line perspective, three-dimensional X line perspective, computer navigation etc.In the said method, electrophysiologic monitoring is round-about way, can not reflect the puncture of pedicle of vertebral arch and the position of screw intuitively, thereby and have only when puncture inaccurate or pedicle screw malposition and cause nerve injury just can produce electrophysiologic response later on and provide caution, be the prompting of property afterwards, not forward-looking and real-time.Though and method image-guided and monitoring has certain objectivity and real-time, but still can not reflect the accuracy of pedicle of vertebral arch puncture and the integrity in pedicle of vertebral arch bone duct fully, and it is expensive to waste time and energy, particularly not only price is high as computer navigation system, use complicated, and the empirical factor that is subjected to user influence very big, the image-guided radiolesion that has increased patient and patient simultaneously.Based on this, over nearly two, three years, there is the author to attempt adopting ultrasonic method to guide the placement of pedicle screw abroad.Because ultrasonic for the basic not damaged of human body, and have better targeted and definitiveness.But the ultrasonic method of external report has plenty of hypothesis pedicle of vertebral arch duct to be worn out, cause that by ultrasonic muscle contraction is monitored its electrophysiologic response on every side, have plenty of and use the cardiovascular ultrasonic probe to survey after the pedicle of vertebral arch duct is made, still do not have real-time and perspective, same price costliness is operated also more numerous and diverse.
The utility model content
The purpose of this utility model is to design a kind of pedicle of vertebral arch supersonic sounding instrument.Design principle of the present utility model is the principle of ultra sonic imaging: in tissue, the acoustic impedance characteristic difference of different tissues is obvious, soft tissue average out to 1.524, and skeleton is 5.570, the acoustic impedance characteristic is more low, its ultra sonic imaging is more clear, according to the ultra sonic imaging principle, designs a kind of pedicle of vertebral arch supersonic sounding instrument.
To be solved in the utility model is that deviation appears in existing normal aggregates bit bore easily, and utilizes CT, X ray computer image navigation boring cost height, the problem of complicated operation.
The technical solution of the utility model is: this utility model comprises pedicle of vertebral arch drill bit, computer, the display that is connected with computer, the pedicle of vertebral arch drill bit comprises drill body and handle, built-in at least one miniature ultrasonic probe in drill body top, miniature ultrasonic control head is connected with the ultrasonic signal gain amplifier, the ultrasonic signal gain amplifier is connected with signal processor, and signal processor is connected with computer; Miniature ultrasonic probe is used for emission and receives ultrasonic signal; The ultrasonic signal gain amplifier is used for the probe ultrasonic signal that receives is amplified; Signal processor is for the treatment of the ultrasonic signal after amplifying and be converted to picture signal, and computer is used for receiving picture signal and handles the back and shows by display.
The utility model has the advantages that: 1, the application of pedicle of vertebral arch supersonic sounding instrument can be avoided the damage of spinal nerves, blood vessel and peripheral internal organs on the one hand, avoid on the other hand because of the blind repeated localised puncture of wearing, influence the curable grip and stability of screw, thereby accuracy and the safety that can improve pedicle of vertebral arch boring greatly or put nail; 2, have simple to operate, easy to use, image is objective, and advantage such as production cost and use cost be cheap; 3, ultrasound wave has safety, the characteristics that have no side effect substantially simultaneously.
Description of drawings

Fig. 2 is the structural representation of this utility model drill body.
The specific embodiment
Below in conjunction with drawings and the specific embodiments this utility model is further described.
As shown in the figure, this utility model bag pedicle of vertebral arch drill bit, computer, the display that is connected with computer.The pedicle of vertebral arch drill bit comprises drill body 1 and handle 2, the built-in miniature ultrasonic probe 6 of drill body 1 top one side, the built-in same miniature ultrasonic probe of corresponding opposite side.Miniature ultrasonic control head and ultrasonic signal gain amplifier lead to and connect.The ultrasonic signal gain amplifier is connected by lead 3 with signal processor 4, and signal processor 4 is connected with computer by lead 5.
Described ultrasonic signal amplifier is low noise ultrasonic signal amplifier, and it is built in the handle hands 2.
Drill body 1 top is provided with the miniature ultrasonic probe installation cavity.Two miniature ultrasonic probe are installed in this installation cavity.Be provided with the ultrasonoscopy processing module for the treatment of picture signal in the computer.Drill bit is provided with scale 7.
Miniature ultrasonic probe is used for emission and receives ultrasonic signal; The ultrasonic signal gain amplifier is used for the probe ultrasonic signal that receives is amplified; Signal processor 4 is for the treatment of the ultrasonic signal after amplifying and be converted to picture signal, and computer is used for receiving picture signal and handles the back and shows by display.
Operation principle of the present utility model: big according to osseous tissue and soft tissue acoustic impedance property difference, the characteristics that osseous tissue acoustic impedance characteristic is strong, ultrasound wave is basic in osseous tissue to be total reflection, be that its echo is stronger, and can not show the soft tissue structure at osseous tissue rear preferably, thereby when this utility model drill bit is positioned at osseous tissue fully, be strong echo, pass osseous tissue and work as drill bit, can show the soft tissue ultrasonogram when entering surrounding soft tissue, according to these characteristics, when use has the bit bore of ultrasonic probe, can monitor the integrity in pedicle of vertebral arch bone duct in real time, thereby in time adjust.
