The invention relates to a surgical instrument, in particular to an ureteroscope which comprises a lens tube. The lens tube is connected with a lens tube main body, the lens tube comprises an end part, a bending part and an inserting part which are connected with one another in sequence, one end of the inserting part is connected with the lens tube main body, the inserting part is a nonabrasive lens tube, a bending operation part which controls the bending part is arranged on the lens tube main body, a first channel is arranged in the lens tube, a second channel is arranged in the lens tube main body, the first channel is communicated with the second channel to form a multipurpose channel, and a detachable support rod or a detachable surgical instrument is arranged in the multipurpose channel. The ureteroscope is simple in structure, has both advantages of a soft lens tube and a hard lens tube, can bend to adapt to the structure of a kidney, is convenient to use and high in safety, and greatly relieves sufferings of a patient. In addition, the ureteroscope solves the technical problems that the ureteroscope in the prior art is either a soft lens tube or a hard lens tube and operation is inflexible.
Description
technical field [0001] The invention relates to a surgical instrument, in particular to a urinary system operation or various pioneering and minimally invasive operations, as well as non-invasive routine inspections. Background technique [0002] With the development of science and technology, there are more and more instruments in modern surgical operations. Surgical instruments can help doctors complete operations and improve convenience and safety. At present, there are separate flexible ureteroscopes and rigid ureteroscopes in the world. The rigid ureteroscope is easy to operate, and can easily reach the renal pelvis through the ureter, such as the Chinese patent: "A combined rigid ureteroscope (CN201929938U)", including a rigid ureteroscope body and a tubular mirror sheath set outside the tubular part of the mirror body, and the mirror sheath The starting end of the mirror body is closely attached to the tubular part of the mirror body. The rear end of the mirror sheat...
