Description

Ureter soft lens sheath

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a ureteral soft endoscope sheath.

Background

A flexible ureteroscope sheath (also called flexible ureteroscope delivery sheath) is an auxiliary instrument necessary for flexible ureteroscope holmium laser lithotripsy.

The existing soft endoscope sheath has the advantages that the tube diameter cannot be changed, the damage to the wall of the ureter is increased, and meanwhile, the tube placing mode adopts a blind tube placing mode, so that the situations of tube detachment, puncture on the kidney, ureter tearing, ureter damage peripheral tissues puncture and the like are easily caused.

In view of this, a ureter soft endoscope sheath is especially provided.

SUMMERY OF THE UTILITY MODEL

In order to solve the existing problems, the utility model provides a flexible ureteroscope sheath. The utility model discloses a following technical scheme realizes.

A ureter soft endoscope sheath comprises a soft endoscope sheath body;

the soft lens sheath body is including supplying the convex screw thread seal wire pipeline that the seal wire put into, be equipped with the hose that the seal wire was walked to 1.2mm in the convex screw thread seal wire pipeline, the syringe needle connector that is equipped with 20ml is connected to the other end of hose, the terminal outwards symmetry of convex screw thread seal wire pipeline is equipped with the handle that is the T style of calligraphy.

Furthermore, the length of the convex thread guide wire pipeline is 50cm, and the diameter of the convex thread guide wire pipeline is 8mm.

Further, the spiral distance of the convex thread guide wire pipeline is 2.5cm.

Further, the diameter of the guide wire is 0.8mm.

The utility model has the advantages that: the utility model is used for ureter soft lens operation, prevents ureter wall damage caused by repeated endoscope entering, reduces intra-renal pressure during operation, reduces bacteremia and kidney damage caused by high intra-renal pressure, and improves the lithotriptic rate; can adapt to the ureter conditions with various sizes and calibers, and can not consider the physiological stenosis of the ureter; the diameter of the sheath can be slightly changed within a certain range, so that the damage to the wall of the ureter can be greatly reduced, and the situations of tube detachment, puncture of kidney, ureter laceration, puncture of tissues around the ureter damage and the like caused by blind tube placement can be completely avoided.

Detailed Description

The technical solution of the present invention will be described in more detail and fully with reference to the accompanying drawings.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

In the specific embodiment 1, the ureter soft lens sheath comprises a soft lens sheath body,

the soft lens sheath body comprises an external convex thread guide wire pipeline 1 for placing a guide wire 2 with the diameter of 0.8mm, the length of the external convex thread guide wire pipeline 1 is 50cm, the diameter of the external convex thread guide wire pipeline is 8mm, and the spiral distance of the external convex thread guide wire pipeline is 2.5cm;

a hose 3 with 1.2mm of guide wire is arranged in the outward convex thread guide wire pipeline 1, and the other end of the hose 3 is connected with a 20ml syringe needle connecting port 4;

the tail end of the external convex thread guide wire pipeline 1 is symmetrically provided with a T-shaped handle 5 which can be hooked by fingers.

The specific using process is as follows:

disease species: various ureteral upper segment stones and kidney stones are subjected to soft lens operation, partial hard lens operation and PCNL operation;

because the outer guide wire is of a soft structure before being placed, the guide wire can be shaped into a linear strip along the zebra guide wire or the loach guide wire, the zebra guide wire or the loach guide wire is placed in a target position through a ureteral hard endoscope, the placed undeployed sheath is stabilized, the guide wire is placed from a guide wire cavity channel on the outer side, the sheath can be unfolded into a circular sheath cavity along with the extension of a spiral, and the hard endoscope can synchronously follow the guide wire in the sheath to check the advancing position and the real-time condition of the guide wire.

The flexible soft endoscope sheath can adapt to the conditions of ureters with various diameters and does not consider physiological stenosis of the ureters;

the pipe placing method comprises the following steps: firstly, a linear sheath is arranged along the zebra guide wire, then the pipeline is expanded along the guide wire cavity channel outside through the same guide wire, the diameter of the formed sheath can be slightly changed within a certain range, and the damage to the wall of the ureteral wall can be greatly reduced compared with the existing soft endoscope sheath with the diameter which can not be changed; compared with the blind tube placing mode of the soft endoscope sheath, the soft endoscope sheath can almost completely avoid the situations of tube detachment, kidney puncture, ureter laceration, ureter damage peripheral tissue puncture and the like caused by blind tube placing.
