Description
Technical field
This utility model relates to medical surgical instrument ultrasonic knife technical field, is specifically related to the anti-skidding jaw of a kind of ultrasonic knife.
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, ultrasonic knife is just more difficult to the process such as blood vessel, lymphatic vessel more than 5mm, and the probe of cutter head bar front portion is generally cylindric or as the flat of Herba sagittariae pygmaeae, when jaw closes up clamping big muscle tissue, trunk, tendon etc., just be easy to landing, fully effectively can not bite tendon, trunk, big muscle tissue.
Summary of the invention
This utility model is for the deficiency existed in background technology, and the technical problem that solve is: provide a kind of ultrasonic knife effectively clamping trunk, big muscle tissue, tendon.
This utility model is for solving the problems of the technologies described above, the technical scheme taked is: the anti-skidding jaw of a kind of ultrasonic knife, comprise the probe of cutter head bar front portion, interior pipe, outer tube and clamp, cutter head bar is arranged in pipe, outer tube sleeve is contained in interior tube outside, interior pipe can slide anteroposterior relative to outer tube, clamp and interior pipe front end are rotationally connected, clamp forms jaw structure with probe, clamp is provided with gear piece, its improvement is: described gear piece is made up of flat tooth section and long tooth section, and flat tooth section is near interior pipe, and the crown height of long tooth section is higher than the crown height of flat tooth section.
Further, the crown height of described long tooth section, reduces from the termination, outside of long tooth section gradually toward flat tooth section direction.
Further, the teeth shape of described gear piece is equilateral triangle.
This utility model compared with prior art, beneficial effect is: adopt new anti-slip type ultrasonic knife, jaw profile as crocodile mouth, in the operation process of process big muscle tissue, trunk, tendon, can be firm and solid catch muscular tissue, blood vessel, tendon, make it to skid off from jaw.Make operation technique convenient, accurate, improve procedure efficiency, ensure operation safety.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
See shown in Fig. 1 to Fig. 6, the anti-skidding jaw of a kind of ultrasonic knife, comprise the probe 1-1 of cutter head bar 1 front portion, interior pipe 2, outer tube 3 and clamp 4, cutter head bar 1 is arranged in pipe 2, outer tube 3 is sleeved on outside interior pipe 2, interior pipe 2 can slide anteroposterior relative to outer tube 3, and clamp 4 and interior pipe 2 front end are rotationally connected, and clamp 4 forms jaw structure with probe 1-1.Clamp 4 is provided with gear piece 5, and gear piece 5 is made up of flat tooth section 5-2 and long tooth section 5-3, and flat tooth section 5-2 is near interior pipe 2, and the crown height of long tooth section 5-3 is higher than the crown height of flat tooth section 5-2.Vertical dimension crown height refers to from the teeth 5-1 top gear piece 5 to gear piece 5 bottom.
In actual product, two parallel arrangement taked by gear piece 5, to strengthen clamping effect.
The crown height of long tooth section 5-3, reduce gradually from the termination, outside of long tooth section 5-3 toward flat tooth section 5-2 direction, thus it is the highest to form teeth 5-1 outside height, jaw profile is as crocodile mouth, effectively to needing muscular tissue 6 to be processed and the tissue such as trunk, tendon to clamp in operation process, surgical effect and efficiency can be improved like this.
When actual production manufactures, the teeth 5-1 shape of gear piece 5 is equilateral triangle.Teeth 5-1 shape also can be common zig-zag.
Adopt after this utility model, jaw profile as crocodile mouth, in the operation process of process big muscle tissue, trunk, tendon, can be firm and solid catch muscular tissue, blood vessel, tendon, make it to skid off from jaw.Make operation technique convenient, accurate, improve procedure efficiency, ensure operation safety.
