Abstract
The utility model provides an improved disposable cystoscope sheath. The improved disposable cystoscope sheath comprises a sheath tube and a speculum cavity inside the sheath tube, wherein the front end of the speculum cavity is provided with an endoscopic sheath window for sealing the speculum cavity and the endoscopic sheath window is arc-shaped. A central angle corresponding to the arc-shaped endoscopic sheath window is an acute angle. The improved disposable cystoscope sheath has the advantages that the endoscopic sheath window is designed to be arc-shaped, a reflected light radian acquired after calculation is capable of ensuring that reflected light does not appear in a cystoscope field and work of the cystoscope is not influenced, thereby being simple in structure, novel in design, strong in light transmission ability and the like.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially relates to a kind of improved disposable cystoscope sheath.
Background technology
At medical field, such as urology department, related parts of human body inside is checked or during Minimally Invasive Surgery, not only often to use endoscope, also may need simultaneously some operating theater instruments to enter simultaneously human body and cooperate with endoscope and finish corresponding diagnosis or treatment, so a kind of mirror sheath that can hold simultaneously endoscope and operating theater instruments of needs.
Granted publication number has disclosed a kind of disposal vesica urinaria examination mirror sheath for the Chinese patent of CN100569175C, this scheme provides can hold endoscope and operating theater instruments enters the dual pathways mirror sheath structure that inside of human body carries out diagnosis and treatment simultaneously, but this mirror sheath structure also has problems simultaneously, because the disposable cystoscope sheath front end is the transparent spacer layer of sealing.Cystoscope inserts the sight glass chamber of disposable cystoscope sheath, owing to come to throw light on for operation by endoscope, the light that the optical fiber of endoscope emits is entered in the cystoscope visual field by the reflection of endoscope sheath form in operation, uses thereby affect cystoscope.
Summary of the invention
Problem to be solved in the utility model provides a kind of improved disposable cystoscope sheath, especially is fit to related parts of human body inside is checked or Minimally Invasive Surgery.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: improved disposable cystoscope sheath comprises that the sight glass chamber of sheath pipe, described sheath pipe inside, the front end in described sight glass chamber are provided with the endoscope sheath form in sealing sight glass chamber; Described endoscope sheath form is curved.
Further, the central angle corresponding to endoscope sheath form of described arc is acute angle.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, the endoscope sheath form is designed to arc, and the radian that calculates can guarantee that reflected light does not occur in the cystoscope visual field, and then can not affect cystoscopic work; Have simple in structure, modern design, the advantage such as the light transmission capacity is strong.
