Description
Technical field
The present invention relates to the clear stone of laser fiber rubble and attract the feeler lever structure, more particularly, relate to a kind of urinary system calculus intracavity rubble that is used for and attract the feeler lever device with the clear stone of the cohesion arranged type rubble of laser fiber of removing rubble.
Background technology
Urinary system calculus is China's commonly encountered diseases, frequently-occurring disease.Though treatment has got into the Minimally Invasive Surgery epoch by open surgery to urinary system calculus both at home and abroad at present, postoperative residual stones rate height is still distinct issues in the clinical position.
At present, existing pneumatic ballistic lithotripsy, lithotrity effect is better, but belongs to physical method, and impulsive force has caused hemorrhage more and has been difficult to control chip size, calculus and bounced greatly everywhere because of impulsive force and be difficult to the location.Ultrasonic rubble has certain effect, but almost feels simply helpless for accounting for the bigger calculus of hardness such as most calcium oxalate in the urinary calculi disease, and ultrasonic bar generate heat easily the deformation effect ultrasonic energy delivery, easily fracture be not durable, cost performance is low.Add alternately that weak effect often will repeatedly be performed the operation with 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.Existing through the urinary system chamber mirror put into the laser fiber rubble, the lithotrity effect highly significant can only be got a duck eye but optical fiber is tiny at every turn, the scope of attack is too little, the rubble overlong time.More than become the major issue of a puzzlement urologist and vast urinary system calculus sufferer.Do not have also at present that a kind of ability is simple and easy through intracavity mirror operation, no matter soft or hard calculus lithotrity effect is splendid, the scope of attack big, can control that the calculus fragment is more tiny, the wild rapid heat dissipation of art, 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 big, 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 the feeler lever device; It comprises the hollow structure feeler lever; Be connected with a vacuum extractor at the terminal connection tube that passes through of this hollow structure feeler lever; Be provided with preceding lug structure in this hollow structure feeler lever upper front end; 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 to be opened in the structural cohesion formula optical fiber outlet of prolapse and to have and is opened in the terminal optical fiber inlet of hollow structure feeler lever, and bending that each the laser fiber leading section in said optical-fibre channel is slight is drawn in to be arranged in and formed a clear stone structure of cohesion formula optical fiber rubble in the cohesion formula optical fiber outlet.
Attract in the feeler lever device at the clear stone of the cohesion arranged type rubble of above-mentioned a kind of laser fiber, be provided with at least one outer surface groove at the outer surface of said hollow structure feeler lever.
Attract in the feeler lever device at the clear stone of the cohesion arranged type rubble of above-mentioned a kind of laser fiber, all be provided with at least one inner surface recesses at the inner surface of said hollow structure feeler lever.
Attract in the feeler lever device at the clear stone of the cohesion arranged type rubble of above-mentioned a kind of laser fiber, said hollow structure feeler lever is by by groove section feeler lever and be located at this and be made up of the terminal slotless section feeler lever of groove section feeler lever; It is said that groove section feeler lever is arranged is to have the outer surface of groove section feeler lever to be provided with at least one outer surface groove along its length and have groove section feeler lever inner surface to be provided with at least one inner surface recesses along its length and form at this at this.
Attract in the feeler lever device at the clear stone of the cohesion arranged type rubble of above-mentioned a kind of laser fiber, said laser fiber is 3 strands or 4 strands.
Attract in the feeler lever device at the clear stone of the cohesion arranged type rubble of above-mentioned a kind of laser fiber, said connection tube is the lower bending shape connection tube.
Attract in the feeler lever device at the clear stone of the cohesion arranged type rubble of above-mentioned a kind of laser fiber, on said lower bending shape connection tube, be provided with control laser energy emitted laser emission switch, vacuum suction switch.
The present invention is after adopting said structure, and it has following beneficial effect:
The present invention hits calculus through utilizing the bending of multiply laser fiber to draw in to be arranged in cohesion formula optical fiber outlet to go up to form a clear stone structure of cohesion formula optical fiber rubble; Therefore; Its scope of attack is big, calculifragous efficiency is high, has changed that traditional laser single strand optical fiber rubble scope of attack is little, the shortcoming of calculifragous efficiency difference, has also changed the shortcoming of present popular ultrasonic rubble confrontation scleroma stone lithotrity effect difference; 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, so can increase caliber that hollow structure the pops one's head in less shortcoming of attraction passage when changing popular ultrasonic in combination pneumatic ballistic lithotripsy relatively; The optical fiber rubble may command fragment of the clear stone structure of cohesion formula optical fiber rubble relatively evenly, is absorbed about 0.1CM easily.The outer surface groove of hollow structure feeler lever outer surface can make the faster and unlikely obstruction of liquid stream in the lithotriptoscepe operating walk way that the hollow structure feeler lever passed through, the better heat-radiation effect in the 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, so 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 have above advantage, thereby improves operation safety.
After the detailed description that combines advantages embodiment of the present invention, it is clearer that characteristics of the present invention and advantage will become.
