Disposal vesica urinaria examination mirror sheath

Abstract

The invention relates to a disposable cystoscope sheath. To solve the problem of mutual cross-infection during medical inspection. The technical solution adopted is: a disposable bladder inspection mirror sheath, including a sheath tube, a sheath main body, an instrument valve, a short bridge, a water inlet valve and a water outlet valve, and it is characterized in that: said sheath tubes are provided with independent speculum cavities And the instrument channel, the front end of the speculum cavity is provided with a transparent window for sealing the speculum cavity, the front end of the instrument channel is open, the front section of the instrument channel is curved, and forms a certain angle with the front section of the speculum cavity; It is connected with the instrument channel and the main body of the sheath, and the speculum cavity is connected and communicated with the short bridge connected in the main body of the sheath; one end of the instrument valve is inserted in the main body of the sheath, and the other end of the instrument valve is equipped with a rubber cap; the main body of the sheath is provided with an inlet The water valve and the water outlet valve; the water inlet valve, the water outlet valve, the instrument channel and the main body of the sheath communicate with each other. The invention creates an integrated structure, which is simple and convenient to operate, economical, practical and safe.

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
