Technical field
This utility model relates to a kind of medical device for the treatment of calculus, is specifically related to a kind of novel lasertripsy operating grip that uses in the lasertripsy of treatment urinary system calculus.
Background technology
The method of treatment calculus mainly comprises lithotrity in extracorporeal shock-wave lithotripsy (ESWL) and the body at present.Along with the development of chamber mirror technology, lithotrity has obtained application more and more widely in the body.Lithotrity is at present common in the body URL, ultrasonic lithotresis and lasertripsy etc. again.
The method of treatment calculus mainly comprises lithotrity in extracorporeal shock-wave lithotripsy (ESWL) and the body at present.Along with the development of chamber mirror technology, lithotrity has obtained application more and more widely in the body.Lithotrity is at present common in the body URL, ultrasonic lithotresis and lasertripsy etc. again.
Current clinical than the tool potentiality be holmium laser lithotripsy system,, the instantaneous power that can reach kilowatt is enough to pulverize various types of calculus.Its main feature is: rely on optical fibers that laser is imported in the body during operation, optical fiber only needs not need firmly to touch calculus near calculus, is not easy to make the calculus displacement; Fragment behind the rubble is less, is beneficial to the postoperative calculus; Laser possesses favorable tissue cutting and coagulation ability simultaneously, can effectively handle the serious calculus of granulation tissue parcel, improves the rubble success rate.
Although the laser lithotripsy technology has the irreplaceable advantage of additive method, because of current laser lithotripsy machine generally all is directly to carry out rubble with optical fiber, yet the material of optical fiber own is thin and soft, and operating on mobile and location acquires a certain degree of difficulty; And the laser lithotripsy machine do not possess the calculus ability yet, a little less than the postoperative cleaning capacity, thereby influence observe and operation, cause certain potential safety hazard easily.Above-mentioned effects limit this The Application of Technology with popularize.
The utility model content
The purpose of this utility model is, solve above-mentioned these difficult problems, improve the laser lithotripsy technology, thereby provide a kind of novel lasertripsy operating grip, the handle that can link to each other with the laser lithotripsy machine, be used to carry soft optical fiber, make things convenient for the doctor to hand also and more can cooperate with endoscope better, make rubble more convenient to operate; Connect vacuum suction system on the handle, the calculus chip after the powder essence can be excreted.
For achieving the above object, a kind of operating grip that is used for lasertripsy of the present utility model is characterized in that this operating grip is a hollow tubular structure, and its inside is used for optical fibre, and described optical fiber is connected into operating grip by the laser lithotripsy machine and passes.
As a kind of improvement of the present utility model, the described main body of operating handle side branch pipe that stretches out, this side branch pipe is used to connect vacuum suction system, and described side branch pipe is communicated with the pipeline in the main body of operating handle, is used for rubble and carries out vacuum suction with the sucking-off of calculus fragment.Described main body of operating handle/side branch pipe is provided with pressure valve, is used to control the size of captivation.
As another improvement of the present utility model, the front end of described main body of operating handle also is equipped with suction catheter; Described optical fiber is connected into operating grip and is passed suction catheter by the laser lithotripsy machine.Described suction catheter is a probe.
As another improvement of the present utility model, the other end of described main body of operating handle is equipped with the optical fiber pillar by a locking nut, is used for importing and the locking optical fibers.
Major advantage of the present utility model is:
1) for the soft optical fiber in the laser lithotripsy provides rigid carrier, make things convenient for the doctor hand-held, and can cooperate with endoscope better, exactly fibre-optical probe is delivered to stone location, also make in the art of crushed stone more convenient to operate.
2) can use existing general ultrasound wave rubble system probe, not need independent configuration.Can select suitable probe according to the dissimilar and growth site of calculus and the demand of endoscope, improve the success rate of operation.
3) can be by connecting vacuum suction system, rubble and calculus process are once finished.
4) seam of connection vacuum suction system is provided with pressure opening and closing valve, is convenient to turnover endoscope of system.Pressure-regulating device is arranged in addition, the size of may command captivation on the handle.
5) handle terminal with compact integral structure practicality is easy to installation and removal, and is easy to operate.

The specific embodiment
This utility model is made by medical 304 (0Cr18Ni9) rustless steel, main body is a tubular structure, inner hollow, front end is used to install suction catheter (can utilize existing various general ultrasound wave rubble system probe, hereinafter to be referred as probe), the other end is installed locking nut and optical fiber pillar, is used for importing and the locking optical fibers.Each parts is hollow.Optical fiber is connected into handle and enters probe interior until stretch out the locking of suitable length (adjustable) back in probe front from the laser lithotripsy machine.The handle main body sidepiece is drawn the arm of a band valve in order to connect vacuum suction system, and negative pressure adjusting device is arranged on the handle in addition, is convenient to regulate with one-handed performance the size of negative pressure suction force.Can be with of the hollow channel sucking-off of calculus chip in the rubble via probe and handle by vacuum suction, general fibre diameter is less than half of handle internal diameter, handle also as attracting passage, has enough spaces to carry out the attraction of calculus fragment except that turnover optical fiber, and fragment finally is by the side branch pipe sucking-off.
In the practical application, when carrying out lithotrity, as depicted in figs. 1 and 2, at the front end of handle 2 probe 1 of screwing on, the optical fiber of laser lithotripsy machine enters in the probe 1 via optical fiber pillar 6 and locking nut 3 and handle 2, and stretches out suitable length and locking from probe 1 other end.Install valve 4 and link to each other with vacuum suction system at the other branch of handle place.
Operating grip main body 2 control laser lithotripsy processes.Valve 4 is used to cut out and opens negative pressure and is beneficial to system turnover endoscope.Regulate pressure-regulating device 5 according to different situations and can obtain suitable negative pressure suction force.
After the laser lithotripsy process is finished, optical fiber extracted out from handle main body 2 and start vacuum suction system begin the calculus process.Valve 4 is in the tight state that closes when initial, and slow rotating valve 4 is adjusted to proper strength with captivation gradually after the unlatching negative pressure, screws valve 4 after calculus is finished and can cut off captivation.
