Description
Technical field
The present invention relates to a kind of surgical medical equipment, more particularly, relate to a kind of ultrasonic cut hemostasis equipment and use and installation method that is used for endoscopic surgery.
Background technology
Along with developing rapidly of modern medicine, ultra-sonic surgical aspirator is applied in the clinical surgery operation treatment more and more, it is applied to surgical operation with ultrasonic energy, its outstanding characteristics are that cutting is meticulous, safety, tissue selectivity and low temperature hemostasis etc., operating means have greatly been enriched, promote operating quality, alleviated patient's slight illness to a certain extent.This ultra-sonic surgical aspirator mainly is made up of main frame, handle, cutter and foot switch.Wherein main frame mainly comprises supersonic signal generator, power amplifier and embedded computer.The ultrasonic signal of telecommunication of small-power that supersonic signal generator produces is after power amplifier amplifies, but the ultrasonic transducer work in the driving handle; Embedded computer mainly is responsible for coordinating and the work of control complete machine, receives control instruction, and the display instrument duty realizes functions such as man-machine interaction and foot-operated control.Embedded computer also will be finished ultrasonic transducer automatic frequency tracking function in addition.Handle comprises ultrasonic transducer and ultrasonic conducting bar, finishes that the ultrasonic signal of telecommunication is changed into ultrasonic mechanical wave, after the ultrasonic conducting bar realizes that amplitude amplifies, is delivered to surgical knife tool.In addition, also is furnished with a multi-purpose shears that tissue (as the organ of pathological changes or blood vessel etc.) grasps that is cut that is used for the patient on the handle.
In american documentation literature US6352532, US6468286, US6669690, disclose several respectively and can be used for the ultrasonic cut hemostasis equipment of endoscopic surgery.
But in existing ultrasonic cut hemostasis equipment, multi-purpose shears in the handle and ultrasonic conducting bar are non-removable.In the middle of endoscope's Minimally Invasive Surgery, in abdominal operation, blood or tissue fluid can flow into along the space between the ultrasonic conducting bar in the rustless steel knife bar outer sleeve of multi-purpose shears and the knife bar inner sleeve.The heat that produces during the work of ultrasonic conducting bar, the blood or the tissue fluid that flow into this space can be solidified, the ultrasonic conducting bar is condensed in the knife bar inner sleeve, thereby the ultrasonic mechanical wave by ultrasonic transducer generating can not conduct to ultrasonic cutter head along ultrasonic conducting bar in the knife bar inner sleeve, can not realize of the cutting of ultrasonic cutter head to soft tissue, the ultrasonic conducting bar can cause operation to end like this, because can not have mutual friction mutually or bonding with the knife bar inner sleeve when the conduction ultrasound wave.If multi-purpose shears in the handle and ultrasonic conducting bar are non-removable, in generation ultrasonic conducting bar in the operation condenses the knife bar inner sleeve, cause the ultrasonic conducting bar can not be when ultrasonic cutter head conduction ultrasound wave, can only scrap multi-purpose shears and ultrasonic conducting bar, multi-purpose shears that more renews and ultrasonic conducting bar, perhaps multi-purpose shears, ultrasonic conducting bar and ultrasonic cutter head as disposable use operating theater instruments, increased the medical expense of hospital so greatly.
In addition, in the multi-purpose shears of existing U.S. Pat 6352532 described ultrasonic cut hemostasis equipment, the knife bar outer sleeve and the knife bar inner sleeve that adopt a kind of bail type structure to finish ultrasonic conducting bar and multi-purpose shears are fixed more, and ultrasonic conducting bar and handle is fixing.But this bail type structure need be done a through hole on the ultrasonic conducting bar, and this through hole causes local stress, causes the fracture of ultrasonic conducting bar during work easily, has shortened the service life of ultrasonic conducting bar.
Summary of the invention: the invention provides a kind of surgical operation cutting and cut with detachable multiple-use, comprise: comprise 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, it is characterized in that the cutting of described surgical operation cuts the combination that can be disassembled into above-mentioned single part or a plurality of parts by one or more links with detachable multiple-use.
