Description

Technical field: [0001] The invention relates to a medical device, in particular to a disposable cystoscope sheath for urology. Background technique: [0002] At present, in the medical field, such as urology, mirror sheaths are often used when performing internal inspections. The disadvantages during use are as follows: First, there is an opening of a certain length at the front end of the sheath tube. In order to prevent the sheath tube from being inserted into the human body and causing damage to the human body, it is necessary to insert an obturator in advance to block the opening, and the sheath tube After being inserted into the human body, it is cumbersome to take out the obturator; secondly, because the insertion of the biopsy forceps is horizontal, in order to take the specimen, it is necessary to insert the manipulator into the sheath in advance, giving the biopsy forceps an angle to take the specimen, and the operation is not easy. The third is that the sheath ha...

The disadvantages during use are as follows: First, there is an opening of a certain length at the front end of the sheath tube. In order to prevent the sheath tube from being inserted into the human body and causing damage to the human body, it is necessary to insert an obturator in advance to block the opening, and the sheath tube After being inserted into the human body, it is cumbersome to take out the obturator; secondly, because the insertion of the biopsy forceps is horizontal, in order to take the specimen, it is necessary to insert the manipulator into the sheath in advance, giving the biopsy forceps an angle to take the specimen, and the operation is not easy. The third is that the sheath has only one lumen, and its front end is open, so that when checking, the obturator, manipulator, speculum and biopsy forceps all pass through one lumen, so that the germs on the patient's body are not only Contaminate the obturator, manipulator, speculum and biopsy forceps, and remain in the inner wall of the sheath. Because the endoscope is expensive, it is used repeatedly after disinfection, and the obturator, manipulator, speculum, biopsy forceps Thorough disinfection of forceps and sheaths is very difficult, especially endoscopes are expensive and cannot be frequently sterilized at high temperature, and the probability of transmission of AIDS, hepatitis B and various infectious diseases is increasing, resulting in cross-infection of the crowd
