Description

Auxiliary supporting guide wire special for ureter distortion

Technical Field

The invention relates to the technical field of medical equipment, in particular to an auxiliary supporting guide wire special for ureter distortion.

Background

Ureteral calculus is one of the most common diseases in urology, along with the rapid development of endoscope technology in more than ten years, ureteroscopic lithotripsy is one of the most common methods for treating calculus in the middle and lower sections of ureter, and compared with traditional ureteroscope incision and stone extraction, the ureteroscopic lithotripsy has the advantages of operation repeatability, noninvasive operation, quick postoperative recovery, less pain of patients and the like, and is widely popularized and used in county hospitals, and the ureteroscope needs to be matched with a corresponding supporting guide wire to provide guidance in the ureter under the ureteroscope so as to facilitate the ureteroscope to be delivered into the body of a patient.

The existing support guide wire has a certain problem when in use, firstly, the existing support guide wire is poor in functionality, generally has a guiding function, can move along a specific track under the operation of a doctor and can guide a ureteroscope, however, when the ureteroscope moves in the ureter of a patient, due to different structures in the ureter of different patients, the cost of the operation is easily increased due to the reasons such as neurogenic bladder, prostatic hyperplasia, retroperitoneal fibrosis, increased pelvic fat, a post-venal ureter and the like, the ureteroscope is small in size and is in full size with normal ureter, the ureteroscope enters the ureter of the patient and is forced to be plugged in, the existing support guide wire cannot expand the ureter which is not marked, and further cannot provide extra utilization for the doctor operation, and meanwhile, the ureteroscope cannot perform medicine feeding operation in the patient, and requires extra catheters to perform medicine feeding, the doctor can easily increase the cost of the operation, the existing support guide wire is poor in functionality, the patient is easy to cause the condition that the ureter is narrow due to the fact that the ureter is in the patient, the ureteroscope moves in the direction of the patient, the ureter is in the patient, the inner wall is difficult to rotate, the guide wire is in the direction of the patient, the patient is difficult to change, the ureter is difficult to perform the operation, the ureter is in the direction is easy to change, the patient is in the inner wall is in the normal operation is required to be bent, and the patient is difficult to change, the patient is in the inner wall is easy to be bent, increase the pain of the patient.

The invention is made to solve the problem that the ureter supporting guide wire is commonly used in the field.
