[0002] When treating diseases such as urethral stricture, calculus or atresia, the pet urethra internal cutting knife usually needs to be inserted into the urethra for operation. In order to ensure that the internal cutting knife does not scratch the normal part of the urethra during insertion, the internal cutting knife is generally stored in a hollow pipe, and the internal cutting knife is brought into the urethra through the pipe. When the internal cutting knife reaches the specified position, the angle of the internal cutting knife is adjusted so that part of the internal cutting knife protrudes outside the hollow pipe for cutting work. Although it can well ensure that the urethra will not be accidentally injured, it still has certain disadvantages. On the one hand, the angle of the internal cutting knife cannot be stably fixed after adjustment, and the angle of the internal cutting knife is easily changed due to the operation of the staff during cutting, thereby affecting the cutting quality. On the other hand, the internal cutting knife installed in the hollow pipe cannot be conveniently assembled and disassembled, so that it cannot be disassembled and cleaned after the operation is completed, thereby making it difficult to clean the hollow pipe and the internal cutting knife, which is time-consuming and labor-consuming, and it is not convenient to replace the internal cutting knife.
