Specific embodiment
The embodiment of the present invention is described in further detail below in conjunction with the accompanying drawings.
Ureteroscope is applied to diagnosis：The upper urinary tract disease that routine inspection cannot make a definite diagnosis has in ureter during radiography full
Defect needs clear and definite property person, unknown cause ureterostenosis or obstruction, and cancer cell, radiography are found in orificium ureteris spray blood or urine examination
Non- lesions showed person.
Flexible ureteroscope is applied to treatment：Upper urinary stone, in being especially located at, the ureteral calculi of hypomere（Laser bullet
Road rubble）With tumour, biopsy, electric torch and excision, placement or taking-up ureter rack tube.
Flexible ureteroscope mainly includes intubation, handle 7, and passes through handle data-interface 8, data cable 9, data wire end socket
10th, host data interface 11 is connected with host 12, and when work also needs to be first turned on host switch 13.
It is intubated as elongated tubular, is made of insertion tube front end 1 and insertion tube bending section 2 and insertion tube 3.
Insertion tube front end 1 is hard metal integral cannula structure, to shorten the French of insertion tube front-end cross-sectional view as far as possible
Perimeter, existing French perimeter are less than 9.6Fr, by the micro-lens 1-1 installed in insertion tube front end, micro lighting module 1-2, work
Passage 1-3, miniature image sensing chip 1-4 positions optimize layout, and insertion tube front end 1,1 ' uses cross section to be circular, ellipse
Circle, the front end of metal sleeve are curved surfaces, surface there are four through hole, respectively with micro-lens of inside installation, miniature
Lighting module, service aisle cooperation, it is harder at insertion tube front-end operations position, it is easy to operation and keep its behaviour in urethra
Control, as shown in Figure 4, Figure 5.
The stage casing of intubation and softer close to fore-end is made of the coiled pipe of outer coated film, can reduce sensitive part
Pressure and sense of discomfort, the back segment insertion tube 3 of intubation makes for hard portion medical plastic or medical composite material, convenient for manipulation.
The stage casing of intubation and back segment are made of identical material, and medical plastic or medical composite material are disposably molded into
Multi-lumen tube has working chamber 1-5, cable chamber 1-6, steel wire chamber 1-7 in figure, as shown in Figure 8.
Micro lighting module 1-2 is connected for multiple or multi-beam lighting fiber 18 and with the LED light source in handle 7
It connects, as shown in fig. 7, the LED light source encapsulated by microsize can also be used, is directly installed on micro-lens in insertion tube front end 1
Both sides, LED light source number be 1 to 2.
Stage casing insertion tube bending section 2 is intubated, can be bent and passive swan-neck 2-2 two to both sides from active swan-neck 2-1
It is grouped into, one end of two steel wires 16 is weldingly fixed in insertion tube front end 1, and the other end of two steel wires 16 is connected to handle steering
On knob 5, insertion tube front end is made to realize the two-way active bending of both direction, when use only needs the handle in rotational handle 7 to turn
To knob 5, each direction bending angle can also place a steel wire in 0~275 degree of scope in intubation, realize a direction
Active bending, as needed select.
Passive swan-neck 2-2 can accordingly be bent with the human lumen being inserted into, passive swan-neck 2-2 and insertion
There are steel wire limiting slot 2-3 in the both sides of 3 junction inner walls of pipe, match somebody with somebody to merge with steel wire 16 and give steel wire positioning, as shown in Figure 6.
The bending direction and angle of insertion tube front end are directly controlled by the variation of 7 position of handle, meets the need of operation
Will, the French perimeter of intubation is less than 9.6 in the range of 8.3~9.6Fr, and service aisle 1-3 French perimeter is in 3.3~3.6Fr models
It encloses, diameter allows common surgical instrument to pass through into vivo at 1.1~1.2 millimeters.
Miniature video camera module built in insertion tube front end 1, it is complete using CMOS miniature image sensing chip 1-4 and size shape
Complete matched micro-lens 1-1 is 1 millimeter × 1 millimeter square plastic camera lens, is miniature image sensing chip 1-4 behind camera lens,
The French perimeter 3.82Fr of chip, camera lens, resolution ratio are not less than 160,000 pixels.Miniature image sensing chip followed by straight
Footpath 0.5~0.6 millimeter of cable 17 but its do not extend into insertion tube front end.
The end of service aisle 1-3 in whole intubation is connected with handle service aisle interface 6, can also be made as attraction channel
With carrying out rubble or taking stone surgical procedure, can also be achieved that spraying function makees cleaning organ, cleaning dirt uses.
Handle 7 and handle insertion interface tube 4, handle service aisle interface 6, handle data-interface 8 thereon, it is disposable to use
Medical plastic or medical composite material injection molding, insertion tube front end 1 are bonded and fixed at the front end of active swan-neck 2-1 with glue
On face, passive bend pipe glue is connected integral with one end of insertion tube 3.
Handle service aisle interface 6 connects threeway, and handle service aisle interface 6 can allow surgical instrument to take stone in vivo by entering
Mesh basket, biopsy forceps etc., can external water injector cleaning camera lens and dirt etc..
It because soft lens endoscopic portion is using electronic component, and takes measures to reduce production cost, therefore can disposably make
With, it realizes under conditions of cross-infection risk is eliminated, promotes Ureteroscopy image resolution ratio height and using effect is good, it is slotting
Enter that pipe front end 1 is subtle, reduce the pain and sense of discomfort of urological surgery patient.Because the input pipe front end of Flexible ureteroscope is
Hard metal overall structure, facilitates insertion into, and carries out being not required to make notch on human body during operative treatment, reduces the damage to tissue
Wound shortens the course for the treatment of, improves curative effect, and popularization of being more convenient for uses.
