Description

Disposable electric Flexible ureteroscope insertion end

Technical field

The chief position of medical instruments field, particularly Flexible ureteroscope is the utility model is related to, it is a kind of disposable Electronics Flexible ureteroscope insertion end.

Background technology

At present, many hospitals also still use the Flexible ureteroscope of fibrescope technology, therefore can not be excessively thick in external diameter Clinical requirement under, the characteristics of resolution ratio is low be present in ureter fiber soft lens, at the same in surgical procedure endoscope distal end it is curved Song operation is also easily caused soft lens and the failure of fibrous fracture occurs.

Though in addition, the existing Flexible ureteroscope for having Imported Electronic endoscopic technique, its is expensive, can only repeatedly sterilize weight It is multiple to use, but linked-together selling use can't be carried out.

Number of patent application 201510199054.X " disposable soft ureteral catheter ", provide only a kind of working portion is The conduit of soft multi-lumen tube, solves the problems, such as existing hose operation underaction, accurate.

The content of the invention

Technical problem to be solved in the utility model is：A kind of disposable electric Flexible ureteroscope insertion end is provided, inserted Enter the fine hard of section diameter, mitigate the discomfort and pain of patient, and image resolution ratio is high, conveniently observes, is easy to doctor Operation technique treatment, simplify the heat dissipation design of whole soft lens device, further simplify manufacture craft, reduce and be fabricated to Originally can be disposable, avoid the risk of cross-infection.

The technical scheme in the invention for solving the above technical problem is：Disposable electric Flexible ureteroscope insertion end, Including front end outer cover by hard, transparent medical or medical composite material injection molding, it is provided with the front end outer cover miniature Camera lens, miniature image sensing chip, service aisle, micro lighting module, the front end outer cover and insertion tube bending section, it is tight respectively Set be covered on the whole outer surface in insertion tube front end connect it is integral, the insertion tube bending section be connected with insertion tube it is integral, There is steel wire stopper slot to coordinate with steel wire on the inwall of junction, the miniature image sensing chip, micro lighting module LED light source Connecting line be connected by cable with handle data-interface.

Compared with prior art, the utility model has the advantage of：This Flexible ureteroscope insertion end is the master of whole soft lens Want, key position, the front end outer cover now made by hard, transparent medical plastic or medical composite material, instead of original with doctor The 26S Proteasome Structure and Function of the insertion tube front end made of stainless steel metal, simplify the heat dissipation design of whole device, effectively reduce front end The temperature rise of shroud surface, further simplifying manufacture craft reduces production cost, is adapted to batch production, in transparent front end outer cover Micro lighting module LED light source is mounted directly, makes maintaining uniform illumination brightness high, the observation for the doctor that is more convenient for and operation technique.

Embodiment

Embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.

For front end outer cover 1 by medical rigid, transparent polymer material injection molding, section can be circular or ellipse shaped like Fig. 2 Circular cross-section is shown, need to be by micro-lens 1-1, micro lighting module 1-2, work to shorten the girth of cross section as far as possible Passage 1-3, miniature image sensing chip 1-4 optimize layout.

The front end face of front end outer cover 1 for closing arc surface, have among arc surface two through hole respectively with micro-lens 1-1, Service aisle 1-3 matchings coordinate, and in micro-lens 1-1 both sides in front end outer cover 1, are mounted directly by microsize encapsulation For LED light source as micro lighting module 1-2, number of light sources is two LEDs, and light source is arranged in the outer cover of clear hard front end, lamp The uniform and can of light effectively suppresses the temperature rise of shroud surface, reduces the design of radiator structure, and manufacture craft is simpler, and doctor is more easy to Observation, operation, control.

The cross section French girth of front end outer cover 1 is in the range of 8.3~9.6Fr.

Micro-lens 1-1 is square, and size is no more than 1 millimeter × 1 millimeter, and French girth is no more than 3.82Fr, micromirror Head is close to miniature image sensing chip 1-4 below, and size is no more than 1 millimeter × 1 millimeter, and French girth is no more than 3.82Fr, point Resolution is not less than 160,000 pixels, and camera lens, chip can keep camera lens minimum French girth using the design of formed objects, shape On the premise of, farthest utilize 160,000 pixels of sensing chip.

Service aisle 1-3 is applied in whole Flexible ureteroscope insertion tube.At 1.1~1.2 millimeters, French girth exists internal diameter 3.3~3.6Fr scopes, can allow conventional operating theater instruments by and enter internal stone extraction basket, biopsy forceps etc., also there is water spray Make cleaning organ, cleaning dirt uses and suction function.

Insertion tube front end 1-5 be with stainless steel make both ends open sleeve pipe, front end outer cover 1 with the inner on inner stopper and Inner stopper on the one end of insertion tube bending section 2, it is locked and is bonded and fixed on insertion tube front end 1-5 whole outer surface respectively, Including insertion tube front end 1-5 is completely covered, insertion tube front end plays a part of supporting front end outer cover 1 and whole insertion tube 3.

One end of two steel wires 16 is weldingly fixed on insertion tube front end 1-5 stainless steel sleeve, and the other end is connected to handle On steering knob 5, there are steel wire stopper slot 2-3 and steel wire 16 to make it fixed with merging in insertion tube bending section 2 and the junction of insertion tube 3 Position, as shown in figure 4, only need the handle steering knob 5 in rotational handle 7, steel wire 16 can two-way active bending, each direction bending Angle is in 0~275 degree of scope, as shown in fig. 6, can also place the active bending that a steel wire realizes a direction, as needed Selection.

Insertion tube bending section 2 is made using the coiled pipe of outer coated film, by active swan-neck 2-1 and passive swan-neck 2-2 groups Into, the pressure and sense of discomfort of sensitive part can be reduced, insertion tube 3 is that hard portion medical plastic or medical composite material make, The manipulation being conveniently maintained in urine output road.

Also insertion tube bending section 2, insertion tube 3 can be made using identical material, of medical plastic or medical composite material Multi-lumen tube disposably is molded into, inside has working chamber 1-8, cable chamber 1-6, steel wire chamber 1-7, as shown in Figure 5.
