Abstract
The utility model provides an improved disposable endoscope sheath, which comprises a sheath tube, an inlet valve and an outlet valve, wherein a water inlet channel, a water outlet channel and at least one main operation channel are arranged on the sheath tube; the water inlet channel is connected with the inlet valve; and the water outlet channel is connected with the outlet valve. The utility model has the beneficial effects that: the technical scheme is adopted, water enters through the water inlet channel to support a surgical part before the surgery, meanwhile, impurities at the surgical part are discharged from the water outlet channel, so the surgical visual field is clear and visible, the operation is accurate, and the surgery is easy to operate and control; and meanwhile, the main operation channel is prevented from being contaminated.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially relates to a kind of improved disposable endoscope mirror sheath.
Background technology
At medical field; Such as urology department; To checking or during Minimally Invasive Surgery related parts of human body inside; Use endoscope, perhaps also possibly need simultaneously some operating theater instruments to get into human body simultaneously and cooperate with endoscope when accomplishing corresponding diagnosis or treatment, needing a kind of mirror sheath that can hold endoscope and operating theater instruments simultaneously.Granted publication number has disclosed a kind of disposal vesica urinaria examination mirror sheath for the Chinese patent of CN100569175C; This scheme provides can be held endoscope and operating theater instruments simultaneously and get into the dual pathways mirror sheath structure that inside of human body carries out diagnosis and treatment, but this mirror sheath structure also existing problems simultaneously: when using time property endoscope, because endoscope's mirror sheath sheath pipe does not have the water-in and water-out passage; Water can only get into and outflow from main operation passage (for example sight glass passage or instrument channel) through the control into and out of water valve; Pollute the main operation passage easily, and the capacity of patient part is limited, so the visual field is unclear; Operation technique is inconvenient
Summary of the invention
It is accurate that the matter of utmost importance that this utility model will solve provides a kind of operation technique that can make, and controls conveniently, can not pollute the main operation passage the endoscope's mirror sheath that has the water-in and water-out passage.
For solving the problems of the technologies described above, the technical scheme that this utility model adopts is: improved disposable endoscope mirror sheath, comprise sheath pipe, water intaking valve and outlet valve, and intake tunnel, exhalant canal and at least one main operation passage are arranged on the said sheath pipe; Said intake tunnel connects water intaking valve; Said exhalant canal connects outlet valve.
Further, the diameter of said sheath pipe is 7.5mm-9.0mm.
Further, said intake tunnel and exhalant canal are separate, are distributed in the both sides of main operation passage respectively.
Advantage and the good effect that the utlity model has are: adopt technique scheme; Before operation, intake and prop up operative site, get rid of the impurity of operative site simultaneously through drainage channel, make surgical field of view limpid visible through intake tunnel; Operation is accurately controlled conveniently; Avoid polluting the main operation passage simultaneously.

The specific embodiment
Like Fig. 1-shown in Figure 9; This utility model is that example describes with one and two main operation passages respectively: the improved disposable endoscope mirror of this utility model sheath; Comprise sheath pipe 1, water intaking valve 30 and outlet valve 40, intake tunnel 3, exhalant canal 4 and at least one main operation passage 2 are arranged on the sheath pipe 1; Intake tunnel 3 connects water intaking valve 30; Exhalant canal 4 connects outlet valve 40.The diameter of sheath pipe 1 is 7.5mm-9.0mm.Intake tunnel 3 is separate with exhalant canal 4, is distributed in the both sides of main operation passage 2 respectively.
Like Fig. 1-shown in Figure 4, for the processing dimension of the sheath pipe 1 that has a main operation passage 2 be shaped as:
1) as shown in Figure 3; The diameter of sheath pipe 1 is 7.5mm; The main operation passage 2 that to get through a diameter above that be 4.0mm is got through an intake tunnel 3 and an exhalant canal 4 respectively in the both sides of main operation passage 2, be to save the space; Dwindle mirror sheath volume and diameter, the water-in and water-out passage is the proximate ellipse of sealing;
2) second kind of processing method is in order to make processing more convenient; As shown in Figure 4; The main operation passage 2 that it is 4.0mm that the sheath pipe 1 that is 7mm-7.5mm with a diameter is earlier got through a diameter digs out an intake tunnel 3 and an access way 4 respectively in the part except that main operation passage 2 on the sheath pipe 1 again, and the water-in and water-out passage of this moment does not seal; Sealing ring of reuse surrounds sheath pipe 1; Glued joint sealing with sheath pipe 1, make that the water-in and water-out passage is a closed channel, this moment, sheath pipe 1 integrally-built diameter was 8.0mm.
As Fig. 5-shown in Figure 9 for the processing dimension of the sheath pipe 1 that has two main operation passages 2 be shaped as:
1) as shown in Figure 7, the diameter of sheath pipe 1 is 8.5mm, earlier gets through two main operation passages 2 above that respectively, intake tunnel 3 and the exhalant canal 4 that diameter is 2.5mm that to get through a diameter respectively in the both sides of main operation passage 2 be 2.5mm;
2) for saving the space, increase the area of water-in and water-out passage simultaneously, as shown in Figure 8, the water-in and water-out passage of getting through is the proximate ellipse of sealing;
3) more convenient in order to process; As shown in Figure 9; Being 8mm-8.5mm with a diameter, sheath pipe 1 is of the method for processing water-in and water-out passage in second kind of processing method of first kind of embodiment, on sheath pipe 1, digs out two main operation passages 2, an intake tunnel 3 and an access way 4 respectively, and two main operation passages 2 and the water-in and water-out passage of this moment all do not seal; Sealing ring of reuse surrounds sheath pipe 1; Glued joint sealing with sheath pipe 1, make four passages form closed channel, this moment, sheath pipe 1 integrally-built diameter was 9.0mm.
More than two embodiment of this utility model are specified, but said content is merely the preferred embodiment of this utility model, can not be considered to be used to limit the practical range of this utility model.All equalizations of doing according to this utility model application range change and improve etc., all should still belong within the patent covering scope of this utility model.
