Description
Technical field
The present invention relates to a kind of surgical medical equipment and a kind of scalpel, more particularly, relate to a kind of ultrasonic cut anthemorrhagic operation system and a kind of surgical operation and cut with detachable ultrasonic cut hemostatic cutter.
Background technology
Modern medicine development is swift and violent, and ultrasonic cut anthemorrhagic operation system is applied in the clinical surgery operation treatment at large, and it utilizes ultrasonic energy to carry out surgical operation, and its outstanding characteristics are that cutting is meticulous, safety, tissue selectivity and low temperature hemostasis etc.Operating means have greatly been enriched in the use of ultrasonic cut anthemorrhagic operation system, have promoted operating quality, have alleviated to a certain extent patient's pain.Ultrasonic cut anthemorrhagic operation system mainly is comprised of main frame, ultrasonic handpiece, ultrasonic knife bar and foot switch, multi-purpose shears.Wherein main frame mainly comprises supersonic signal generator, drive circuit and master controller.Supersonic signal generator drives ultrasonic handpiece work by drive circuit; Master controller wherein mainly is responsible for coordinating and the work of control complete machine, receives control instruction, and the display instrument duty realizes the functions such as man-machine interaction and foot-operated control.Ultrasonic handpiece can be converted into the ultrasonic electric signal ultrasonic mechanical wave, is delivered to surgical knife tool.Multi-purpose shears is provided on the ultrasonic handpiece, is used for grasping patient's the tissue that is cut.
In american documentation literature US6352532, US6468286, US6669690, disclose respectively several and can be used for the ultrasonic cut hemostasis equipment of endoscopic surgery.
But in existing ultrasonic cut hemostasis equipment, ultrasonic handpiece and ultrasonic knife bar are non-removable.In the middle of endoscope micro-wound, in abdominal operation, blood or tissue fluid can flow into along the space between multi-purpose shears and the ultrasonic knife bar.The heat that produces during ultrasonic knife bar work can be solidified the blood or the tissue fluid that flow into this space, and ultrasonic knife bar is bonded in the multi-purpose shears, conducts along ultrasonic knife bar thereby hinder ultrasonic mechanical wave, affects ultrasonic cutter head to the cutting of soft tissue.If non-removable ultrasonic knife bar and ultrasonic handpiece are bonded in the multi-purpose shears, can cause ultrasonic knife bar not conduct ultrasound wave to ultrasonic cutter head, the multi-purpose shears that can only more renew and ultrasonic knife bar, perhaps use disposable multi-purpose shears, ultrasonic knife bar, ultrasonic handle of a knife, so greatly reinforcement the medical expense of hospital.
In addition, in the multi-purpose shears of existing US Patent No. 6352532 described ultrasonic cut hemostasis equipment, adopt a kind of bail type structure to finish the fixing of ultrasonic knife bar and multi-purpose shears, and ultrasonic knife bar and handle is fixing more.But this bail type structure need to be done a through hole at ultrasonic knife bar, and this through hole causes local stress, easily causes the fracture of ultrasonic knife bar during work, has shortened the service life of ultrasonic knife bar.
The described surgical operation of existing China Patent Publication No. CN1875889A is with detachably cutting multi-purpose shears, its structure comprises: ultrasonic conducting bar, knife bar inner sleeve, knife bar outer sleeve, assembling sleeve and handle, wherein the knife bar outer sleeve is enclosed within the outside of knife bar inner sleeve, the ultrasonic conducting bar is contained in the knife bar inner sleeve, can be disassembled into by one or more links the combination of above-mentioned single part or a plurality of parts.But, this multi-purpose shears complex structure, part is various, mounts and dismounts all very difficultly, is unfavorable for very much using in the operation, has increased greatly operator's operation easier, operate miss easily occurs with unexpected.
In addition, in the existing ultrasonic cut anthemorrhagic operation system, it is breakneck that ultrasonic cut anthemorrhagic operation system breaks down, and not only the effect of impact operation more can impact patient's safety.These faults comprise that being connected of ultrasonic knife bar and ultrasonic handpiece is loosening, and ultrasonic knife bar and multi-purpose shears rub, and the transducer in the ultrasonic handpiece breaks down, and ultrasonic knife bar cracks etc.Ultrasonic knife bar is done dither for a long time as critical component, has the danger of fracture.In case the fracture phenomenon not only affects the operation process, even can patient's safety be worked the mischief.In the existing ultrasonic cut anthemorrhagic operation system, also the ultrasonic cut anthemorrhagic operation system failure there is not the function of active prevention and warning.
Summary of the invention
The purpose of this invention is to provide a kind of ultrasonic cut anthemorrhagic operation system and a kind of surgical operation cuts with detachable ultrasonic cut hemostatic cutter.
