drawings
The present application will be further described with reference to the accompanying drawings and examples, in which:
FIG. 1 is a schematic structural diagram of a special ureteral catheter for fixing a flexible ureteroscope sheath according to one embodiment of the application;
FIG. 2 is a schematic view of a clip holding a flexible sheath according to an embodiment of the present application.
Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application. Also, the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
As shown in fig. 1, the ureter for fixing the ureteroscope sheath according to an embodiment of the present application includes a first tube 11 and a second tube 12, the second tube 12 is connected to the end of the first tube 11, the second tube 12 has a larger diameter than the first tube 11 and forms a variable diameter transition section 121 at the connection with the first tube 11, so as to reduce the insertion resistance of the ureter and the possible damage to the patient, and facilitate the use. The center of the head end 13 of the first tube 11 is provided with a wire guide hole 131 through which 0.035 and 0.038 inch wires can pass, and the head end is developed under perspective. The sidewall of the head end 13 of the first pipe 11 is opened with two head end side holes 132 opposite to each other in the radial direction for better water outlet. The head of the first tube 11 is further provided with a balloon 15 behind the head side hole 132, and the second tube 16 is provided with a balloon water injection port 16 communicated with the balloon 15, and the balloon water injection port 16 can be communicated with the balloon 15 through, for example, a pipeline provided in the second tube 12 and the first tube 11. When the ureter is kept in place, water is injected into the sacculus 15 through the sacculus water injection port 16 to enable the sacculus 15 to be expanded into a spherical shape, so that the ureter can be prevented from falling off during operation. The length L of the first tube 11 from the rear end of the balloon 15 to the front end of the variable diameter transition section 121 of the second tube 12 is an effective insertion length, and the length L is different for men and women so as to be matched in different ureteral soft endoscope sheaths. For example, in one embodiment, the effective insertion length L of the first tube 11 is 20cm for males and 5cm for females.
As further shown in fig. 1, the second tube 12 is provided with a triple external fixation device for fixing the ureteral soft sheath. The first is a self-adhesive tape 17 arranged on the second tube body 12 and used for adhering and binding the ureter soft endoscope sheath. The second is a retaining clip 18 disposed on the second tube 12 for holding the ureteral sheath. Referring specifically to fig. 2, the fixing clip 18 may be of a conventional clip structure, and the clipping ends of the two clipping arms 181 of the fixing clip 18 are further provided with clipping pads 182 adapted to the outer circumference of the ureteral soft endoscope sheath 20 so as to clip the ureteral soft endoscope sheath 20 more firmly. The third is that two tail end side holes 141 are further formed in the side wall of the tail end 14 of the second tube body 12 behind the fixing clip 18, and a thread can be threaded through the tail end side holes 141 for binding the handheld position of the ureteral soft endoscope sheath.
