Abstract
The utility model discloses a kind of Flexible ureteroscopes, which is characterized in that including clamping device, camera lens and work cavity；The camera lens is arranged on work cavity front end, and the work cavity rear end is provided with controller, and the controller of the work cavity is fixedly connected with clamping device by connection sheet, and the clamping device is hollow cylinder, intermediate projections, and inner wall coarse；The utility model provides a kind of combination and takes the Flexible ureteroscope of stone, to being collected postoperative rubble convenient for medical research etc..
Description
Technical field
The utility model relates to area of medical devices, more specifically, it is related to a kind of Flexible ureteroscope.
Background technique
Ureteral calculi is usually kidney stone in discharge process, is temporarily obstructed caused by the stenosis of ureter.Such as
Ureteral calculi is not discharged, and may gradually grow up stopping position.Ureteral calculi generally entails apparent symptom, such as kidney
Colic pain, blood urine, ureteral calculi also often result in obstruction and uronephrosis, these require emergency treatment.Ureteroscope stone-extraction operation is
Ureteroscope per urethram enters in ureter through bladder, calculus is taken out using set stone mesh basket or lithotomy forceps, or in ureteroscope
It is lower to use the rock crushing plants such as pneumatic ballistic lithotriptor, laser lithotripsy machine, lower accurate rubble is pried through in ureteroscope guidance, calculus is hit
Broken, then liquid, rubble etc. outside mirror body directly by being expelled directly out.
Laser lithotripsy machine mostly uses Bladder stone at present, very shallow to the penetration depth of tissue, is 0.4mm.In medical treatment
In research, it is often necessary to postoperative lithotrity effect be studied and be assessed, in the hope of the improvement of next time.It is difficult to reduce again now
Degree of injury, and the requirement that rubble is disposably collected.
Summary of the invention
The utility model overcomes the deficiencies in the prior art, and postoperative rubble can be collected by providing one kind, into one
Step reduces the Flexible ureteroscope of degree of injury.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is as follows:
A kind of Flexible ureteroscope, including clamping device, camera lens and work cavity；The camera lens is arranged in work cavity front end
On, the work cavity rear end is provided with controller, and the controller and clamping device of the work cavity are fixed by connection sheet
Connection, the clamping device are hollow cylinder, intermediate projections, and inner wall coarse, the camera lens center be provided with diameter 2 to
The cylindrical channel of 5mm, the both ends of the cylindrical channel are provided with disengaging control film, and it is logical that the disengaging control film covers cylinder
Road.
Further, the clamping device is transparence, using the highly endothermic material of high resiliency.
Further, the disengaging control film is fixedly connected at least 3 points or more of cylindrical channel.
Advantage is the utility model compared with prior art:
1, the design of the utility model structure is simple, reasonable, easy to make, practical, easily promote the use of.
2, the fixed collection of calculus can be avoided part rubble from not being discharged and cause two by the clamping device of the utility model
Secondary injury.
3, the utility model is by setting disengaging control film, to extend the service life of Flexible ureteroscope.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of Flexible ureteroscope of the utility model；
Fig. 2 is the company of the cylindrical channel and disengaging control film in a kind of camera lens of Fig. 1 of Flexible ureteroscope of the utility model
Connect schematic diagram.
Specific embodiment
The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1, a kind of Flexible ureteroscope, including clamping device 1, camera lens 2 and work cavity 3；The camera lens 2 is arranged
On 3 front end of work cavity, clamping device 1 is transparence, this allows for camera lens 2 convenient for the kidney internal junction of observation operative site
The internal environment of structure or upper section ureter is exactly found calculus position.2 center of camera lens is provided with tiny cylindrical channel
5, cylindrical channel 5 is convenient for the disengaging of Bladder stone optical fiber, carries out laser lithotripsy.3 rear end of work cavity is provided with controller 4,
The controller 4 of work cavity 3 is fixedly connected with clamping device 1 by connection sheet 7, and allows clamp structure 1 with control
Device 4 slides in the wall of work cavity 3, entire clamping device 1 can completely into (not shown) in the inner wall of work cavity 3,
1cm can also be stretched out.When the clamping device 1 all stretches out 1cm, clamping device 1 is hollow cylinder, and intermediate projections.I.e.
As moving up and down for controller 4 will drive the promotion of connection sheet 7, connection sheet 7 pushes the disengaging work cavity of clamping device 1
In 3 wall, because of the unique global shape and high resiliency of clamping device 1, so that driving clamping device 1 toward extrapolation in controller 4
When, clamping device have one section of diameter expand outwardly become larger and process that after-contraction becomes smaller.Because of 1 inner wall coarse of clamping device,
So that certain fixed function can be played to calculus when determining calculus position, rubble is carried out convenient for Bladder stone, and clamp
Mechanism 1 uses the effect of the highly endothermic material of high resiliency, so that can further decrease Bladder stone pair when Bladder stone carries out rubble
The injury of human body, and the rubble after smashing is still in the encirclement range of clamping device 1, convenient for by rubble with clamping device 1 one
And take out of, the rubble of taking-up will be seen that the effect of this time operation, facilitate medical research and assessment successful surgery degree.
As shown in Fig. 2, 2 center of camera lens is provided with tiny cylindrical channel 5, the both ends of cylindrical channel 5 are provided with disengaging
Film 6 is controlled, disengaging control film 6 can cover cylindrical channel 5.The disengaging control film 6 is fixedly connected with 5 multiple spot of cylindrical channel,
And the range of fixed point 61 is not more than the half of entire disengaging control film 6, i.e., disengaging control film 6 is averagely allocated as two halves, only
Fixed point 61 is arranged in half wherein, is convenient for the disengaging of Bladder stone optical fiber in this way, and can effectively completely cut off the intracorporal liquid of people and enter
Flexible ureteroscope extends the service life of surgical apparatus.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
Art personnel can also make several improvements and modifications without departing from the concept of the premise utility, these improvements and modifications
Also it should be regarded as in scope of protection of the utility model.
