Description
Technical field
The present invention relates to probe, more particularly, relate to a kind of clear stone of the cohesion arranged type rubble of laser fiber for urinary system calculus intracavity rubble and removing rubble and attract feeler lever device.
Background technology
Urinary system calculus is China's commonly encountered diseases, frequently-occurring disease.Although urinary system calculus treatment has been entered to the Minimally Invasive Surgery epoch by open surgery both at home and abroad at present, postoperative residual stones rate is high is still distinct issues in clinical position.
At present, existing pneumatic ballistic lithotripsy, lithotrity effect is better, but belongs to physical method, and impulsive force has more caused hemorrhage and has been difficult to control chip size, calculus and bounces greatly everywhere and be difficult to location because of impulsive force.Ultrasonic rubble has certain effect, but almost feels simply helpless for accounting for calculus that the hardness such as most calcium oxalate are larger in urinary calculi disease, and ultrasonic bar easily generate heat deformation effect ultrasonic energy delivery, easily fracture be not durable, cost performance is low.Alternately add that weak effect is often wanted Repeated Operation by the loaded down with trivial details length consuming time of method of air pressure trajectory associating rubble, effect and social cost's burden are all not satisfactory.Existingly through urinary system chamber mirror, put into laser fiber rubble, lithotrity effect highly significant can only be got a duck eye but optical fiber is tiny at every turn, and the scope of attack is too little, rubble overlong time.More than become the major issue of a puzzlement urologist and vast urinary system calculus sufferer.Also there is no at present that a kind of energy is simple and easy by chamber endoscopic technic, no matter soft or hard calculus lithotrity effect is splendid, the scope of attack large, can control that calculus fragment is more tiny, visual area rapid heat dissipation, absorb that fragment does not block, long-lived desirable calculi breaking device self does not generate heat fast.
Summary of the invention
The object of the present invention is to provide that a kind of operation is simple and easy, no matter soft or hard calculus lithotrity effect is splendid, the scope of attack large, fast rubble, absorb fragment and the clear stone attraction of the cohesion arranged type rubble of long-lived laser fiber feeler lever device.
To achieve these goals, the present invention has adopted following technical scheme:
The clear stone of the cohesion arranged type rubble of a kind of laser fiber attracts feeler lever device, it comprises hollow structure feeler lever, at this hollow structure feeler lever end, by a connection tube, be connected with a vacuum extractor, lug structure before this hollow structure feeler lever upper front end is provided with, and, in this hollow structure feeler lever, be provided with the optical-fibre channel that can hold at least 2 strands of laser fibers, this optical-fibre channel has and is opened in the structural cohesion formula optical fiber outlet of prolapse and has the optical fiber entrance that is opened in hollow structure feeler lever end, the slight bending gathering of each laser fiber leading section in described optical-fibre channel is arranged in cohesion formula optical fiber and exports and a clear stone structure of cohesion formula optical fiber rubble of formation, described hollow structure feeler lever is by by groove section feeler lever and be located at this slotless section feeler lever by groove section feeler lever end and form, it is described that to have groove section feeler lever be have the outer surface of groove section feeler lever to be provided with along its length at least one outer surface groove and have groove section feeler lever inner surface be provided with along its length at least one inner surface recesses and form at this at this.
At the clear stone of the cohesion arranged type rubble of above-mentioned a kind of laser fiber, attract in feeler lever device, at the outer surface of described hollow structure feeler lever, be provided with at least one outer surface groove.
At the clear stone of the cohesion arranged type rubble of above-mentioned a kind of laser fiber, attract in feeler lever device, at the inner surface of described hollow structure feeler lever, be all provided with at least one inner surface recesses.
At the clear stone of the cohesion arranged type rubble of above-mentioned a kind of laser fiber, attract in feeler lever device, described laser fiber is 3 strands or 4 strands.
At the clear stone of the cohesion arranged type rubble of above-mentioned a kind of laser fiber, attract in feeler lever device, described connection tube is lower bending shape connection tube.
At the clear stone of the cohesion arranged type rubble of above-mentioned a kind of laser fiber, attract, in feeler lever device, on described lower bending shape connection tube, to be provided with Laser emission switch, the vacuum suction switch of controlling laser energy transmitting.
The present invention is after adopting said structure, and it has following beneficial effect:
By utilizing the bending of multiply laser fiber to draw in to be arranged in, cohesion formula optical fiber outlet is upper forms a clear stone structure of cohesion formula optical fiber rubble calculus is hit in the present invention, therefore, its scope of attack is large, calculifragous efficiency is high, changed traditional shortcoming that the laser single strand optical fiber rubble scope of attack is little, calculifragous efficiency is poor, also changed the current popular poor shortcoming of ultrasonic rubble confrontation scleroma stone lithotrity effect, the present invention's soft or hard calculus lithotrity effect is all splendid, and it is rubble and absorption fragment fast.Because laser fiber takes up space seldom, therefore the caliber that can relatively increase hollow structure probe less shortcoming of attraction channel when changing popular ultrasonic in combination pneumatic ballistic lithotripsy; The optical fiber rubble of the clear stone structure of cohesion formula optical fiber rubble can be controlled fragment in 0.1CM left and right, more even, easily absorbs.The outer surface groove of hollow structure feeler lever outer surface, can make the faster and unlikely obstruction of liquid stream in lithotriptoscepe operating walk way that hollow structure feeler lever passes through, the better heat-radiation effect in rubble.The inner surface recesses of hollow structure feeler lever inner surface can avoid vacuum extractor when negative pressure sucking-off calculus fragment, to cause obstruction.Contrast echo feeler lever technology, feeler lever of the present invention is not the carrier that energy passes through, and himself does not generate heat, therefore feeler lever of the present invention can be durable in use, its application life is longer.The present invention can reduce remnant gallstone rate owing to having above advantage, thereby improves operation safety.
After reading by reference to the accompanying drawings the detailed description of embodiments of the present invention, it is clearer that the features and advantages of the invention will become.
