Abstract
The invention relates to an instrument used for a medical minimally invasive operation, in particular to an ultrasonic lithotriptor. The ultrasonic lithotriptor comprises an ultrasonic transducer which is sleeved with an operating handle shell outside and is connected with a stone-breaking amplitude transformer, wherein a working channel is arranged in the stone-breaking amplitude transformer, one end of the working channel is arranged on the working face of the stone-breaking amplitude transformer, while the other end is connected with two channels, one channel is a water inlet channel connected with a water inlet, and the other channel is a suction channel connected with a suction interface. The invention mainly provides the ultrasonic lithotripter used together with an endoscope in a minimally invasive operation, can completely adsorb stones, then break up the stones, and suck the stones out of a body through pipelines without causing the broken stone to enter the kidney to damage a human body; therefore, the ultrasonic lithotripter solves the technical problems that the prior art cannot break the stones thoroughly from the outside and cause damages to the human body.
Description
Technical field
The present invention relates to a kind of medical Minimally Invasive Surgery instrument, relate in particular to a kind of ultrasound lithotriptor.
Background technology
Because calculus appears in the intravital ureter of people, kidney, gallbladder and bladder, people healthy caused very big influence, often need hospital admission, need intravital these calculus are smashed, so that dissolving, thereby the slight illness of elimination human body.Existing lithotripsy in treatment generally adopts the method for extracorporeal shock-wave lithotripsy (ESWL).Mainly refer to the ultrasound wave external stone crushing.As Chinese patent: " portable external ultrasonic lithotriptor " (CN1085415), it is made up of supersonic sounding instrument and transducer.The transducer of the peripheral low frequency of mesopore high frequency is associated between pulse generator and the preamplifier.Said structure is found out the calculus place earlier by survey meter, then it is smashed, to cause litholysis.This instrument belongs to the method for outside rubble, rubble might be squeezed in the kidney in the rubble process, causes the damage to human body, and broken not thorough of calculus, is not easy dissolving and excretes.
Summary of the invention
The present invention mainly provides a kind of being applied in the Minimally Invasive Surgery, and with the matching used ultrasound lithotriptor of endoscope, it can adsorb calculus then fully and smash, and is external by the pipeline sucking-off then, can not cause rubble to enter in the kidney, causes the infringement of human body; It is not thorough to solve the outside rubble of existing in prior technology, easily to the hurtful technical problem of human body.
It is a kind of simple in structure that the present invention also provides simultaneously, calculifragous efficiency height, the ultrasound lithotriptor that operation safety is high; Solve the external stone crushing device complex structure that exists in the prior art, the technical problem that calculifragous efficiency is not high.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of ultrasound lithotriptor, comprise ultrasonic transducer, described ultrasonic transducer is socketed with the operating grip shell outward, described ultrasonic transducer is connected with the rubble horn, be provided with service aisle in the described rubble horn, one end of described service aisle is arranged on the work surface of rubble horn, the other end is connected with two passages, one of them is an intake tunnel, and described intake tunnel links to each other with water inlet; Another is for attracting passage, and described attraction passage links to each other with attracting interface.Intake tunnel connects outer water tube, water is imported by intake tunnel, attract passage by suction calculus to be adsorbed on the end face of rubble horn, ultrasonic transducer drives the rubble horn calculus is smashed then, and then by attracting passage to take out of the rubble that smashes external by current.Carry out water filling during operation,, realize the continuous I ﹠ A of operative site, and can guarantee the abundant heat radiation at ultrasonic transducer position by intaking and attracting two interfaces.Utilization of the present invention is operated at the handle of ultrasonic transducer outside, utilizes captivation to pulverize after the calculus absorption again, pulverizes thoroughly and be not easy to squeeze in the kidney etc. in the organ, lithotrity effect is good, by water filling sucking-off rubble, make not have by the clean of rubble cleaning residual simultaneously.
As preferably, described attraction passage and intake tunnel are parallel to each other, and the diameter of two passages is identical, and two passages all are positioned at the center of described ultrasonic transducer.Two passages be parallel to each other and diameter identical, convenient processing is independent of each other, and also conveniently simultaneously links with service aisle.Two passages are positioned at the ultrasonic transducer center, convenient be connected with service aisle, the while reasonable use inner space of ultrasonic transducer.
As more preferably, be provided with the connection chamber of bucket shape between described attraction passage and intake tunnel and the described service aisle.At two interchannels the bucket shape connection chamber is set, the one, can alleviate the flow of rubble and current, simultaneously owing to be that service aisle needs to connect respectively attraction passage and intake tunnel, cavity volume is set can not cause rubble and current to stop up because of the problem that is connected so that the connection of two passages is more smooth and easy.
As preferably, be provided with angle between described intake tunnel and the water inlet, described attraction passage and described attraction interface coaxial arrangement.Intake tunnel one end will be connected with service aisle, and the other end connects water inlet again, but limited in the tail end space of handle, and operation for convenience is so be provided with angle between second interface channel and the water inlet.Attract passage and attract interface to constitute a straight passage, can allow the rubble sucking-off more smooth and easy, stuck problem can not occur.Well utilized simultaneously the inner space of ultrasonic transducer, more compact structure.
As preferably, the cross section of described rubble horn is circular, and the external peripheral surface of described rubble horn is the conical surface, and tapering α is 0 °～10 ° round bar shapes that the rubble horn are designed to tapering, energy delivery that can the convenience for ultrasonic wave transducer makes lithotrity effect better.
As preferably, described rubble horn adopts with described ultrasonic transducer and is threaded, and described ultrasonic transducer is threaded with described shell employing.Employing is threaded, and syndeton is simple, and is convenient with two parts disassembly, cleaning.
As preferably, described rubble horn adopts electroforming process integral body to process, and the length of described rubble horn is 100mm～500mm, and the diameter of the operative end surface of described rubble horn is Φ 1mm～Φ 5mm.Adopt the whole processing of electroforming process, improve hyperacoustic transmission efficiency.
As preferably, described water inlet and attract interface all to be arranged on the tail end of described handle.Offer water inlet and attract interface at the handle tail end, make things convenient for the operation of operation, can not interfere with doctor's operation.
Therefore, a kind of ultrasound lithotriptor of the present invention has following advantage: 1, utilize ultrasonic transducer to be connected with the rubble horn, simple in structure, utilize absorption affinity that calculus is adsorbed on the rubble horn, utilize ultrasonic transducer that calculus is smashed then, lithotrity effect is good, and is not easy in the rubble process calculus to be squeezed in the kidney; 2, be provided with intake tunnel and sorption channel in ultrasonic transducer, can realize utilizing current easily rubble to be taken out of, can reduce simultaneously because the heat that the ultrasonic transducer heating produces helps the handle heat radiation, handled easily increases the service life; 3, the rubble horn is the round bar with tapering, and the convenience for ultrasonic wave energy transmits, and improves calculifragous efficiency, improves operation safety.
