Abstract
The utility model discloses a ureter self-bending flushing catheter, which comprises a catheter and a guide wire; the front end of the catheter is provided with a self-bending head, and the guide wire is a hard guide wire. The utility model discloses can become the straight tube when cooperation stereoplasm seal wire, be convenient for put into and walk around the calculus position. When the catheter is smoothly placed into the ureter and crosses the position of the calculus, the guide wire is withdrawn; the front end of the conduit can be gradually and automatically bent by 180 degrees, the water outlet direction is changed, and the flushing is carried out in the forward direction. When the catheter needs to be withdrawn, the guide wire is penetrated again, so that the catheter is straightened again, and the catheter is convenient to withdraw.
Description
Technical Field
The utility model relates to the field of medical equipment, concretely relates to ureter is from crooked pipe that washes.
Background
After ureteroscopy or lithotripsy, the ureter needs to be flushed. The current method of irrigation is to direct water from the ureter into the kidney (retrograde), which then drains the water from the ureter (anterograde). The washing method can increase the pressure of the kidney, and the water flushing quantity cannot be too much, otherwise hydronephrosis, high pressure in the kidney and the like can be caused to cause bleeding and infection; this approach therefore limits the flushing effect on the ureters.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned problem, provide a ureter is from crooked washing pipe. In order to achieve the above purpose, the utility model adopts the following technical scheme:
a ureteral self-bending irrigation catheter, comprising a catheter and a guide wire; the front end of the catheter is provided with a self-bending head, and the guide wire is a hard guide wire.
As a refinement, the bending angle from the bending head is 180 °.
As an improvement, the tail end of the guide pipe is provided with a connector.
The utility model has the advantages that:
the utility model discloses can become the straight tube when cooperation stereoplasm seal wire, be convenient for put into and walk around the calculus position. When the catheter is smoothly placed into the ureter and crosses the position of the calculus, the guide wire is withdrawn; the front end of the conduit can be gradually and automatically bent for 180 degrees and change the water outlet direction, and the flushing is carried out in the forward direction. When the catheter needs to be withdrawn, the guide wire is penetrated again, so that the catheter is straightened again, and the withdrawal is convenient.

Detailed Description
The present invention will be described in detail and specifically with reference to specific embodiments so as to better understand the present invention, but the following embodiments do not limit the scope of the present invention.
Example 1
The embodiment discloses a ureteral self-bending flushing catheter, which comprises a catheter 1 and a guide wire 2.
The front end of the conduit 1 is provided with a self-bending head 3, and the bending angle of the self-bending head is 180 degrees. The guide wire 2 is a hard guide wire.
The utility model can be changed into a straight tube when being matched with the hard guide wire 2, and is convenient for being placed into and bypassing the position of the calculus 5. When the catheter is smoothly placed into the ureter and crosses the position of the calculus 5, the guide wire is withdrawn; the front end of the conduit can be gradually and automatically bent for 180 degrees and change the water outlet direction, and the flushing is carried out in the forward direction. When the catheter needs to be withdrawn, the guide wire is penetrated again, so that the catheter is straightened again, and the withdrawal is convenient.
Example 2
The embodiment discloses a ureteral self-bending flushing catheter, which comprises a catheter 1 and a guide wire 2.
The end of the conduit 1 is provided with a connector 4. Facilitating connection to the flushing device and insertion of the guide wire 2.
The other structure of this embodiment is the same as embodiment 1.
The above detailed description of the embodiments of the present invention is only for exemplary purposes, and the present invention is not intended to be equivalent to the above described embodiments. Any equivalent modifications and substitutions for the present invention are within the scope of the present invention for those skilled in the art. Therefore, the equivalent changes and modifications made without departing from the spirit and scope of the present invention should be covered in the scope of the present invention.
Claims (2)
1. A ureteral self-bending irrigation catheter, which is characterized by comprising a catheter and a guide wire; the front end of the catheter is provided with a self-bending head, and the guide wire is a hard guide wire.
