Description
Technical field
The present invention relates to a kind of armarium, especially relate to a kind of B ultrasonic of extra chock wave lithotriptor that is used for from motion tracking rubble system.
Background technology
Extra chock wave lithotriptor all partly is made up of the most basic rubble system and navigation system two, and accurately the location is the prerequisite of safe and effective rubble, requires calculus can move to exactly and be fixed in the burnt district of the shock wave scope when carrying out lithotripsy in treatment.Existing extra chock wave lithotriptor is mostly good to the therapeutic effect of calculus of urethra, for the treatment of renal calculus just because of renal calculus along with the big calculus hit rate of situation displacements such as breathing of human body is low, cause lithotrity effect poor.In the rubble process, can be along with the fine motion of the impact of patient's breathing, shock wave or position and produces change in the calculus position, according to clinical statistics, people's respiratory frequency on average is 20 times/minute, renal calculus is 2cm with the displacement of each breathing approximately, in conjunction with the relevant parameter of lithotrite, the target area scope is 0.7cm
2, impulse period average out to 1s, the calculus hit rate of renal calculus lithotripsy in treatment is about 66% as can be known, and all the other shock waves of 34% then impact on soft tissue.When the calculus change in location greatly to exceeding the target area scope, and lithotrite still continues impact by the frequency of setting, and will make patient's damage soft tissue, produces serious adverse consequences.Whether the lithotrite of domestic current exposes once when generally having impacted 500～600 times during the X ray location in the rubble process again, observe the calculus position and change, and B ultrasonic when location, though can monitor in real time, the palpus manually-operated, hit rate largely will rely on operator's technology and experience.Therefore, exist exposure frequency to increase, defective such as can not monitor calculus position or operation inconvenience in real time and be difficult for mastering the technique.
The report that aspect, calculus location is abroad arranged, but less than the concrete report from motion tracking rubble aspect.At home, the report of comparison system also is navigation system and device thereof, and the research that the rubble Flame Image Process reaches from motion tracking rubble function all only is in the embryonic stage.
Summary of the invention
The object of the present invention is to provide a kind of extra chock wave lithotriptor that is used for to realize that at the extracorporeal shock-wave lithotripsy (ESWL) therapeutic process B ultrasonic of monitoring in real time and tracking rubble is from motion tracking rubble system, calculus hit rate when making treatment renal calculus improves greatly, thereby the wound that reduces patient's soft tissue has effectively improved calculifragous efficiency.
For achieving the above object, the present invention can realize by following technical measures: the drive circuit that comprises the B ultrasonic machine, stores video analysis and control the microcomputer of output program and be used to trigger the lithotrite rubble, described B ultrasonic machine links to each other with microcomputer through the image collection card interface, the control output that microcomputer produces inserts drive circuit, and described microcomputer comprises:
Locking is with reference to image device, be used to lock a width of cloth and be with the calculus center with reference to image, note residing position of calculus and feature thereof;
Gather in real time and comparison means, be used for Real-time and Dynamic collection current residing position of calculus image calculus and feature thereof that B ultrasonic became, and with current calculus image that this became with compare with reference to image;
Judgment means, be used for when the calculus position of present image and feature with reference to the calculus position of image recording and feature thereof when consistent, promptly the calculus position is still in Jiao district, then control output high level is to drive circuit, otherwise the control output low level arrives drive circuit.
Drive circuit of the present invention comprises photoelectrical coupler, DC relay and Programmable Logic Controller PLC, the outfan of photoelectrical coupler connects the voltage controling end of DC relay, and normally opened contact two junction points of DC relay insert the triggering signal input of Programmable Logic Controller PLC.When drive circuit receives high level, the photoelectrical coupler conducting, DC relay gets electric its contact adhesive that makes, trigger Programmable Logic Controller and export one group of start pulse signal that drives rubble, when drive circuit receives low level, photoelectrical coupler ends, and DC relay gets electric its contact that makes and disconnects, and triggers Programmable Logic Controller and does not export start pulse signal driving rubble.
The present invention compared with prior art has recognition effect and the response speed that is exceedingly fast efficiently.With rubble under the homenergic, use the clinical effectiveness of B ultrasonic of the present invention when motion tracking rubble system rubble to show that the calculus hit rate surpasses 98%, improve hit rate more than 32%, see Table 1.Greatly reduce the wound of soft tissue, effectively improved calculifragous efficiency.
Table 1 is for using the present invention and the clinical comparison of prior art to the required impact number of times of identical calculus
