Background

With the development and progress of science and technology, the requirements of people for things are changed from old thinking that people can use things as things, to be quite fine and exquisite and to be capable of living under the examination of strong market competition only by continuously improving or innovating ideas and generating new forms to improve the added value of products. The ureteroscope is a medical equipment used for urology treatment, is a medical instrument comprising a plurality of working channels and various working accessories with different purposes, the ureteroscope operation is to enter a ureter with the diameter of 0.2-0.5 cm through a slender scope body through a urethra, a bladder and a ureter orifice, and lesions in the ureter, such as stones, tumors and the like, can be observed clearly under direct vision or by means of an image monitoring system, the diagnosis and treatment of ureter diseases are carried out by using the ureteroscope, the diagnosis and treatment level of the ureter diseases are greatly improved, the hospitalization time of patients is shortened, the treatment cost is reduced, and the clinical satisfactory effect can be obtained.

The ureteroscope in the prior art only has one working channel for operation of surgical instruments, generally, a ureteral sheath (UAS) is firstly inserted through blind insertion and then is inserted into a ureteral body through the UAS, the ureteral sheath is positioned in the ureteral sheath, a backflow channel is formed in a gap between the ureteral sheath and the UAS, a sufficient backflow gap is required to be reserved for the ureteral sheath to wrap the ureteral sheath, the size and the specification of the ureteral sheath (UAS) are generally 12 Fr-14 Fr, the diameter is thick, the ureteral mucosa is easy to be damaged by blind insertion, the ureteral sheath is difficult to be placed at an ideal position, backflow is not smooth, the internal pressure of a renal pelvis cannot be effectively reduced, and the diagnosis and treatment effects are influenced, even if the fiber uretero-renoscope with double working channels is provided, the sizes of the two channels are only 3Fr, the channel is too small to facilitate effective backflow, a ureteral sheath is still needed in the operation, and therefore, the uretero-renoscope with the backflow channel without the ureteral sheath is needed.

SUMMERY OF THE UTILITY MODEL

In view of the problems raised by the above background art, the present invention is directed to: aims to provide a ureteroscope with a backflow channel.

In order to achieve the technical purpose, the technical scheme adopted by the utility model is as follows:

a ureteroscope with a backflow channel comprises an operating handle and a ureteroscope body connected with the operating handle and capable of extending into a human body, wherein the diameter of the ureteroscope body is less than or equal to 11Fr, the backflow channel and the operating channel are arranged in parallel inside the ureteroscope body, the diameter of the backflow channel is 5 Fr-Fr, and an illumination light source and an imaging observation window are arranged at the end part of the ureteroscope body.

Further limited, the end part of the mirror body is also provided with an inclined plane, and the port of the backflow channel is arranged on the inclined plane.

Further limiting, the surface of the mirror body is externally coated with a water-soluble super-smooth coating, and the design is easy to slide and good in using effect.

Further, the size of the diameter of the backflow channel is 6Fr, and due to the design, effective backflow can be provided, and meanwhile blockage by broken stones is prevented.

Further limit, the endoscope body is a ureter fiberscope, a ureter electronic endoscope or a ureter nephroscope, and the application range is expanded due to the design.

The utility model has the following beneficial effects:

1. the utility model realizes that an effective backflow channel with proper pipe diameter is directly constructed in the ureteroscope body, the backflow channel is arranged in parallel with other working channels and advances and retreats simultaneously, a ureteral sheath is not used, the using effect is ensured, the overall diameter is reduced, and the damage to ureteral mucosa is reduced;

2. because the illumination light source, the operation channel and the imaging observation window are all positioned on the plane of the end part of the endoscope body, the direct-viewing endoscope can be provided under a clear view field, and ureteral mucosa injury caused by blind insertion is avoided;

3. the endoscope body with the backflow channel can be placed at an ideal position, the backflow channel is closer to the renal pelvis, and the backflow effect is good, so that the internal pressure of the renal pelvis is effectively reduced, and the backflow of urine and flushing fluid is facilitated.
