Description
Technical field
The present invention relates to medical surgical instrument ultrasonic knife technical field, be specifically related to a kind of multiplex cutter head.
Background technology
Ultrasonic knife carries out the surgical apparatus of chamber mirror technology indispensability, by being mechanical energy by electric energy conversion, do not have electric current by patient body.Can carry out cutting and blood coagulation simultaneously, its collection cutting, solidifying close, grasp, be located away from one.Cutting speed is fast, haemostatic effect good, simple to operate, safe ready, greatly can shorten operating time, reduces patient's blood loss and transfusion volume, thus reduces complication and surgery cost.Ultrasonic knife is used in meticulous surgical operation, and be applied in various endoscopic surgery more and more, as: peritoneoscope, prostate are cut in the operations such as mirror, cystoscope, hysteroscope, application in laparoscopically surgical operation has obvious advantage, to the damage of surrounding tissue much smaller than electric knife.
In prior art, ultrasonic knife surgical apparatus comprises the major parts such as main frame, cutter head assembly, transducer, foot switch and connection cable.Main frame produces the signal of telecommunication of 55.5KHz, is transported to transducer produces ultrasound wave by connection cable.
Cutter head assembly, by based on the handle of handgun shape, handle is also connected with the finger that can rotate and holds plate.Be threaded connection between the rear end of the cutter head bar of titanium alloy and transducer, cutter head bar transmits ultrasonic energy.Be set with interior pipe, outer tube outside cutter head bar, interior pipe is between cutter head bar and outer tube, and interior pipe can slide anteroposterior, is socketed in the rubber ring on cutter head bar and inner tube wall tight fit.Outer tube back-end is fixedly connected with control handle, and rear end and the inner pipe joint of interior pipe are fixedly linked, and inner pipe joint offers axial notch.There is returning spring between interior pipe and control handle, realizing by having strong market potential between the axial notch of control handle and inner pipe joint, cutter head bar three synchronously rotating in a circumferential direction.Inner pipe joint is connected with linkage by interior pipe slider, and linkage is held plate with finger again and realized interlock.Holding plate when pressing finger, just can control sliding backward of interior pipe, unclamp finger and hold plate, under the return action of returning spring, interior pipe forward slip is to its normal orientation.Cutter head bar and transducer connector are placed in the taper knob of handle upper portion cavity type, and the inwall of taper knob front end is provided with draw-in groove, and draw-in groove engages mutually with the spring O type circle at control handle rear portion; And the inwall of taper knob rear end is provided with collar, collar engages with the groove of transducer front portion, jointly limits the free vibration in front and back of cutter head bar and transducer connector, and palette knife head rod and transducer connector can circumference rotate.
Interior pipe front end is rotationally connected by pin and clamp, the probe of clamp and cutter head bar front end forms adjustable clamp, when interior pipe slides backward, because outer tube is in relative static conditions, the angle of clamp and probe diminishes gradually, jaw shrink, thus achieve to operation in need clamping of muscular tissue to be processed, blood vessel, tendon.Usually on clamp, gear piece is provided with, to strengthen clamping effect.By regulable control knob, according to the actual needs in operation, can select best angle, being extend into by probe easily and effectively needs muscular tissue to be processed, blood vessel, tendon, efficiently completes operation.
But the frame for movement due to cutter head makes interior pipe and cutter head bar be relatively-stationary, simultaneously interior pipe, outer tube and cutter head bar rotate, therefore in operation process, be only equipped with the cutter head (blunt type or sharp) using a kind of shape, but the cutter head of blunt type is more suitable for coagulation operation, and the cutter head of sharp is more suitable for cutting operation, a kind of cutter head of shape is only had to be difficult to carry out accurate operation technique.
Summary of the invention
The present invention is directed to the deficiency existed in background technology, the technical problem that solve is: provide a kind of probe to have the ultrasonic knife in cutting edge of a knife or a sword knife face, blunt knife face simultaneously.
The present invention is for solving the problems of the technologies described above, the technical scheme taked is: a kind of multiplex cutter head, comprise cutter head bar, interior pipe, outer tube, clamp, handle and control handle, wherein: cutter head bar is arranged in pipe, outer tube sleeve is contained in interior tube outside, and interior pipe can slide anteroposterior relative to outer tube, rear end and the inner pipe joint of interior pipe are fixedly linked, inner pipe joint offers axial notch, and clamp and interior pipe front end are rotationally connected, and clamp is provided with gear piece; Outer tube back-end is fixedly connected with control handle, and control handle rear portion is connected together by the taper knob of spring O type circle and handle upper portion, and its improvement is: the probe of cutter head bar front portion is made up of cutting edge of a knife or a sword knife face and blunt knife face; Control handle rear portion is provided with set screw, and set screw front end is arranged in described axial notch; Locking device is provided with between taper knob and cutter head bar.
Further, described locking device comprises cutter head base, lock gear and locking press button, and cutter head base, lock gear are fixed on cutter head bar, and order is positioned at cutter head bar rear portion, and cutter head pan frontward end is near inner pipe joint; On taper knob, part corresponding with lock gear offers slotted eye, and locking press button is fixed in slotted eye;
When pressing locking press button, locking press button and lock gear are mutually meshing.
Further, described locking press button is made up of lock body, lock tube, spring and lock tooth, and lock body is T-shaped, and lock tube and spring order are socketed on lock body, and spring is between lock body and lock tube, and lock body lower end is connected with lock tooth; Lock tube is fixedly connected with slotted eye;
When pressing down lock body, lock tooth is mutually meshing with lock gear.
Compared with prior art, beneficial effect is in the present invention: operator according to surgery situation, same operating theater instruments can use the cutter head (blunt type or sharp) that two kinds dissimilar.In order to reach better operation coagulation effect, cutter head can being changed into blunt type easily, also in order to reach better surgical cut effect, cutter head can be changed into sharp, help operator meticulousr, carry out operation easily.
