Abstract
The utility model discloses a supersonic probe used for pulverizing intracavity calculi and cleaning calculi of the urinary system, which is provided with a probe rod (2), an ultrasonic energy transducer and a negative-pressure suction device, wherein the probe rod and the ultrasonic energy transducer are hollow, one end of the ultrasonic energy transducer is connected with the left end of the probe rod by screw threads, and the other end of the ultrasonic energy transducer is provided with a protruded and hollow connection tube (5) which is connected with the outside-arranged negative-pressure suction device by a soft tube. The utility model changes the mode of high-pressure injection and using forceps for taking the calculus out after calculus pulverization in the traditional holmium laser or air-pressure trajectory operation, uses ultrasonic sound and negative pressure for directly pulverizing calculus and sucking out the calculus, can greatly improve the operation speed and reduce the residual calculus rate. The negative pressure suction can guarantee the low pressure in the kidney and improve the operation safety.
Description
Technical field
This utility model relates to probe, particularly a kind of ultrasonic probe that is used for urinary system calculus intracavity rubble and removes calculus.
Background technology
Urinary system calculus is the commonly encountered diseases of Urology Surgery, except smaller calculus can by take medicine and extracorporeal shock-wave lithotripsy (ESWL), quite vast scale part calculus sufferer needs rubble operative treatment in the receptive cavity.Pneumatic ballistic lithotripsy in the past, the ultrasonic rubble of holmium laser lithotripsy, electrohydraulic lithotripsy feeler lever all are solid, crushed stone in vivo, can't directly be scavenged into calculus external, can only lean on high pressure pouring and pliers to take out calculus, the method operating time is long, postoperative remnant gallstone rate height, and high pressure pouring also can cause the kidney inner high voltage, and then causing kidney damage, operation risk is big.And the calculus of using the vacuum extractor cleaning to pulverize merely because the calculus chip size differs, is easy to cause suction catheter to stop up, and the vacuum extractor suction pipe is too thick, and when attracting calculus with the suction pump cleaning, endoscope can't observe.Also do not have at present a kind ofly can the while clean out external device to the rubble powder again with the supporting effectively rubble of existing various intracavity rock crushing plants.
Summary of the invention
Technical problem to be solved in the utility model is: at existing intracavity rubble surgical technic defective, provide a kind of not only can crushed stone but also can remove the probe of calculus fast.
The technical scheme that its technical problem that solves this utility model adopts is: be provided with feeler lever, ultrasonic transducer and vacuum extractor, wherein, described feeler lever and ultrasonic transducer are hollow structure; One end of ultrasonic transducer and the left end head of feeler lever are threaded, and the other end of ultrasonic transducer is provided with outstanding hollow connection tube, and this hollow connection tube is with hose connection external vacuum extractor.
This utility model utilizes the ultrasonic transducer of hollow and the feeler lever of hollow to transmit energy, both can effectively transfer energy to stone location and carry out the intracavity rubble, can utilize the passage of this hollow again, connecing vacuum extractor is scavenged into calculus external, because ultransonic vibration is arranged, also overcome hollow feeler lever blocking problem simultaneously.Having changed intracavity Urology Surgery rubble operation in the past can't rubble and remove the problem that calculus is finished simultaneously, can improve operation efficient, reduces remnant gallstone rate, and vacuum suction can keep low pressure in the kidney, improves operation safety.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. ultrasonic transmitter; 2. feeler lever; 3. titanium alloy pipe fitting; 4. aluminium alloy pipe fitting; 5. hollow connection tube.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
This utility model provides is used for urinary system calculus intracavity rubble and removes the ultrasonic probe of calculus, its structure as shown in Figure 1: be provided with feeler lever 2, ultrasonic transducer and vacuum extractor.Described feeler lever and ultrasonic transducer are hollow structure.One end of ultrasonic transducer and the left end head of feeler lever are threaded, and the other end of ultrasonic transducer is provided with outstanding hollow connection tube 5, and this hollow connection tube is with hose connection external vacuum extractor.
Described ultrasonic transducer, from left to right form by the aluminium alloy pipe fitting 4 with hollow structure, ultrasonic transmitter 1 and the titanium alloy pipe fitting 3 of adhesion successively, wherein: the end face middle part of aluminium alloy pipe fitting 4 is provided with outstanding hollow connection tube 5, and titanium alloy pipe fitting 3 is threaded with the left end head of feeler lever 2.On ultrasonic transmitter 1, be provided with the on and off switch of control ultrasonic energy emissions and vacuum suction.
Described ultrasonic transmitter 1, it can tranmitting frequency be the ultrasound wave that is not less than 24KHz.
This utility model changes in the past in holmium laser or the air pressure trajectory operation process calculus will get cubic meter of stone formula with high pressure pouring with pliers after pulverizing, and can carry out the work that calculus is removed in ultrasonic rubble and vacuum suction simultaneously.Concrete work process of the present utility model is: endoscope enters after the operative site, the service aisle and the image system that provide according to endoscope provide surgical field of view, feeler lever 2 enters from the service aisle of endoscope, arrive position, calculus place, after the hollow connection tube 5 of ultrasonic transducer is by hose connection vacuum extractor, open ultrasonic energy emission and suction shaft, the energy of ultrasonic transducer generating transmits through feeler lever 2 and arrives stone location, utilizes hyperacoustic high-energy crushed stone; Utilize negative pressure that the powder of calculus is attracted out simultaneously, thereby reach the purpose of rubble and removing calculus.
