The bottom of the endoscope bridge is provided with an endoscope locking device. The improved disposable endoscope sheath is advantageous in that: the length of the endoscope chamber passage which is obtained through insulating the metal pipe can be adjusted appropriately; a problem of low convenience in adjusting the endoscopes with different operation lengths is settled; simultaneously the strength of the endoscope sheath is improved and high sealing performance is obtained.
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; 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.By avoiding endoscope to be polluted by apparatus, the sight glass tract of disposable endoscope sheath and instrument channel be independent isolating separately.
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; Sight glass tract front end seals with transparent visual screening glass; In use, endoscope's sight glass tract of packing into, endoscope's eyepiece end should unrestrictedly be pressed close to sight glass tract closed front; The endoscope rear end is connected locking with the mirror bridge portion terminal lock lens device of mirror sheath, forms the isolated effect of endoscope.Because sight glass tract front end adopts the rigidity sealing; The entire length that has limited the sight glass tract is immutable; And different endoscope's working portion length there is some difference, following problem can appear: the one, when endoscope being put into sight glass tract front end and puts in place, as easy as rolling off a log mirror bridge terminal lock lens device and the endoscope's connecting portion locking that can not put in place that causes; Can't realize connecting, like the long transparent visual screening glass of hindering sight glass tract front end that possibly push up again of endoscope; The 2nd, though the terminal locking of endoscope and mirror bridge, the unfavorable distance of formation influences field of view between endoscope distal end and the transparent visual screening glass of sight glass tract front end, more than two all cause endoscope normally to use.
Summary of the invention
The problem that this utility model will solve provides that a kind of endoscope that can make different operating length is convenient to be connected with the mirror sheath, can increase endoscope's mirror sheath of the removable sight glass tract that has metal tube of intensity and good airproof performance simultaneously.
For solving the problems of the technologies described above; The technical scheme that this utility model adopts is: a kind of improved disposable endoscope mirror sheath; Comprise sheath cover, mirror sheath main body and be connected the intravital Jing Qiao of mirror sheath master, sight glass sheath cover rear end is connected with mirror sheath main body, and said sight glass sheath cover is isolated by metal tube becomes independently metal speculums tract; Sight glass sheath cover front end is open opening, and opening is provided with the annular stop platform;
The visual screening glass of metal tube front end installing sealed transparent in the said sight glass sheath cover, the position of transparent visual screening glass keeps an adjustable distance apart from sight glass sheath cover front end;
Said mirror bridge end is provided with the lock lens device.
Further, the rear and front end is provided with supporting layer in the said sight glass sheath cover cavity, scribbles annular silica gel between metal tube and the supporting layer.
Further, said metal tube adopts welding to be connected with the gummed mode with transparent visual screening glass.
Further, said mirror sheath main body is provided with water intaking valve and outlet valve, and said metal tube rear end length surpasses the water intaking valve be connected with mirror sheath main body and outlet valve and communicates with Jing Qiao.
Further, said sight glass sheath cover front end outer surface is the circular arc of protuberance.
Further, said metal tube is a stainless steel tube.
Advantage and the good effect that the utlity model has are:
1, the sight glass sheath cover intracavity stainless steel metal pipe of packing into forms independently sight glass tract, and has strengthened sight glass sheath cover bulk strength, makes operation safe, the convenience of endoscope;
2, the circular arc design that is protuberance of sight glass sheath cover front end outer surface can make things convenient for the sheath cover to insert human body; Damage when avoiding inserting; There is the annular stop platform at sight glass sheath cover front opening place, can effectively limit and scurry when the metal speculums tract moves to sight glass sheath cover front end;
3, the front loaded position of metal tube keeps a distance apart from sight glass sheath cover front end; Pushing away metal tube before the different operating length according to endoscope during the dress mirror moves; Until the terminal lock of sight glass connecting portion and the mirror bridge lens device locking that puts in place; It is suitably adjustable that sight glass tract length is become, and solved the problem that the inconvenience of different operating length sight glass connects;
4, the rear and front end is provided with supporting layer in the sight glass sheath cover cavity; Can the support metal pipe and it is moved forward on supporting layer; Scribble silica gel between metal tube and the supporting layer; Because of silica gel has certain elastic deformation, be beneficial to metal tube and move and seal, guarantee that endoscope distal end and the transparent visual screening glass in the metal partial view mirror tract closely pressed close to;
5, metal tube rear end length communicates with outlet valve and with Jing Qiao above water intaking valve, avoids Inlet and outlet water to flow into the sight glass tract and pollutes sight glass, guarantees the isolation of sight glass tract;
6, the transparent visual screening glass of the visual windows of metal tube front end plays the effect of sealing sight glass tract, guarantees visible observation, and the visual windows screening glass adopts welding to be connected with metal tube with the gummed mode, has strengthened connectivity robustness, can bear certain thrust.
