With the foregoing drawings in mind, certain embodiments of the disclosure have been shown and described in more detail below. These drawings and written description are not intended to limit the scope of the disclosed concepts in any way, but rather to illustrate the concepts of the disclosure to those skilled in the art by reference to specific embodiments.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Reference herein to "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

Referring to fig. 1, a schematic structural diagram of a surgical urethrocystoscope sheath provided by an exemplary embodiment of the present application is shown, and referring to fig. 2, a schematic usage scenario diagram of the surgical urethrocystoscope sheath in fig. 1 is shown.

As shown in fig. 1 and 2, the urethra-bladder endoscope sheath for operation comprises a sheath tube 10, a water inlet valve 20, a water outlet valve 30, a quick connector 40 and a sheath 50.

As shown in fig. 1 and 2, the sheath tube 10 is connected to the sheath 50, the sheath 50 is connected to the quick connector 40, the inlet valve 20 and the outlet valve 30 are disposed on opposite sides of the quick connector 40, and the inlet valve 20 is disposed near the sheath tube 10.

In a possible embodiment, under the using condition of the urethra-bladder endoscope sheath for operation, the quick interface 40 is connected with an obturator which is inserted into the endoscope sheath tube 10 through the quick interface 40; further, the obturator is pulled out under the condition that the sheath of the urethra-bladder endoscope for operation is inserted into the urethra.

Optionally, the water inlet valve 20 is used for injecting physiological saline when in use; optionally, the outlet valve 30 is adapted to discharge waste water when in use.

Unlike the sheath tube design of the related art, the sheath tube 10 of the present embodiment has a corrugated groove on the surface thereof, through which air and water inside the urethra are discharged to the outside.

As shown in fig. 3, which shows a cross section S1 of the surgical urethrovesico-endoscope sheath of fig. 1, and as shown in fig. 4, which shows a cross section S2 of the sheath tube of the related art.

As can be seen from fig. 4, in the related art, the section S1 of the sheath tube has a circular tube cross-section shape, so that when the sheath of the urethrovesico endoscope is used for operation, the contact surface of the sheath tube is the whole tube surface; as can be seen from fig. 3, in the embodiment of the present application, since the corrugated groove is formed on the surface of the sheath tube 10, the sheath tube 10 has a cross-sectional shape of a tube with different shape, when the sheath of the urethrocystoscope for operation functions, the contact surface of the sheath tube is a convex surface of the corrugated groove, that is, under the same diameter model, the contact area of the sheath tube in fig. 3 is smaller than that of the sheath tube in fig. 4, so that when the sheath of the urethrocystoscope for operation is inserted into the urethra, the sheath of the urethrocystoscope for operation corresponding to the design in fig. 3 is not easy to bleed, and is safer.

In summary, in the embodiment of the present invention, a urethra-bladder endoscope sheath for operation is provided, in which the corrugated groove is formed on the surface of the sheath tube, so as to reduce the problem of urethral mucosa injury bleeding caused by a large friction force of the sheath tube during operation, and effectively reduce the contact surface through the groove, thereby reducing the insertion resistance; in addition, the corrugated groove can be used for passing liquid, so that air and water in the urethra can be discharged out of the body through the groove during insertion, and the friction force during insertion is further relieved.

The utility model is not to be considered as limited to the particular embodiments shown and described, but is to be understood that various modifications, equivalents, improvements and the like can be made without departing from the spirit and scope of the utility model.
