Abstract
The utility model provides a disposable two-channel endoscopic sheath of an endoscope. The disposable two-channel endoscopic sheath comprises a sheath tube formed by an endoscope cavity and an instrument channel which are respectively independent, wherein, a transparent window for sealing the endoscope cavity is arranged at the front end of the endoscope cavity; the front end of the instrument channel is open; and a swell further arranged at the lower part of the front end of the endoscope cavity is positioned in front of an opening of the instrument channel. The disposable two-channel endoscopic sheath has the advantages and the benefits that as the technical scheme is adopted, after a surgical instrument extends out of the instrument channel, as the front end of the surgical instrument is limited by the smooth swell, the advancing axial direction of the surgical instrument is deviated and a certain distance is produced between the surgical instrument and the front end of the endoscope cavity, so that the transparent window of the endoscope cavity is avoided from being shielded and then the observation of the endoscope can not be influenced.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially relates to a kind of disposable dual pathways mirror sheath that can hold endoscope and operating theater instruments simultaneously.
Background technology
At medical field; Such as urology department; To checking or during Minimally Invasive Surgery related parts of human body inside; Not only often to use endoscope, also possibly need some operating theater instruments to get into human body simultaneously simultaneously and cooperate corresponding diagnosis of completion or treatment with endoscope, therefore need 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 has problems simultaneously; One of them be stretch out the operating theater instruments of instrument channel might be because of self deformational stress or inside of human body extruding; Its termination can shelter from the transparent window in part or all of sight glass chamber, causes influencing the observation of endoscope, and then influences diagnosis and treatment process and effect.
Summary of the invention
The problem that this utility model will solve provides a kind of dual pathways endoscope mirror sheath that can avoid operating theater instruments to influence the endoscope visual field.
For solving the problems of the technologies described above; The technical scheme that this utility model adopts is: disposable dual pathways endoscope mirror sheath; Comprise that the front end in said sight glass chamber is provided with the transparent window in sealing sight glass chamber by the sheath pipe formed of sight glass chamber and instrument channel independently separately, the front end of instrument channel is an open type; It is characterized in that: the front end bottom in said sight glass chamber also is provided with a protuberance, and protuberance is positioned at the place ahead of instrument channel opening.
Further, other part junctions of the surface of said protuberance and sheath pipe are smooth transition.
Further, said projecting shape cross section is a trough shape, and the trough bottom is higher than the bottom of instrument channel.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme; After operating theater instruments is stretched out instrument channel; Its front end is owing to receive the restriction of smooth protuberance, and advance shaft produces certain distance to departing from sight glass chamber front end; Avoid blocking the transparent window in sight glass chamber, and then can not influence the observation of endoscope.

The specific embodiment
As shown in Figure 1; The disposable dual pathways of this utility model endoscope mirror sheath; Comprise that the front end in said sight glass chamber 2 is provided with the transparent window 6 that seals the sight glass chamber by the sheath pipe 1 formed of sight glass chamber 2 and instrument channel 3 independently separately, the front end of instrument channel 3 is an open type; Also be provided with a protuberance 4 in the front end bottom in sight glass chamber 2, protuberance 4 is positioned at the place ahead of instrument channel opening.After operating theater instruments was stretched out instrument channel, its front end was owing to receive the restriction of smooth protuberance, and advance shaft produces certain distance to departing from sight glass chamber front end.
Further, other part junctions of the surface of said protuberance and sheath pipe are smooth transition.The resistance that can receive when making the operating theater instruments front end run into protuberance is very little.
Further, said projecting shape cross section is a trough shape, and the trough bottom is higher than the bottom of instrument channel.This set is to push ahead for operating theater instruments, and its front end is run into when protuberance, and it is little not only to receive resistance, and departing from of producing is also not too large.
More than the embodiment of this utility model is 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.
