Embodiment Construction

[0040] Such as figure 1 The multipurpose ureteroscope balloon guide wire shown includes a guide wire sheath, a guide wire core 1 inserted in the guide wire sheath, and a Y-shaped joint 4 fixedly connected to one end of the guide wire sheath, It is characterized in that: the distal end of the outer sheath of the guide wire is provided with an expandable balloon 2; the inner cavity of the expandable balloon is the same as the branch tube of the Y-shaped joint to form a fluid-filled channel.

[0041] The front and rear ends of the expandable balloon are fixed on the guide wire outer sheath 2 .

[0042] The operation method of the above-mentioned multi-purpose ureteroscope balloon guide wire in clinical application is as follows:

[0043] 1) See you first diagram 2-1 , 2-2 As shown, the expandable balloon at the front end of the guide wire is in a flattened state, and enters the ureteral orifice together with the ureteroscope through the urethra, so that the front end of the u...

Abstract

The invention relates to a multipurpose ureteroscope sacculus guidewire and a using method thereof. The multipurpose ureteroscope sacculus guidewire comprises a guidewire sheath (3), a guidewire core (1) penetratingly arranged in the guidewire sheath (3) and a Y-shaped connector (4) fixedly connected with one end of the guidewire sheath, and is characterized in that an expandable sacculus (2) is arranged at the far end of the guidewire sheath, and an inner cavity of the expandable sacculus (2) and branch ducts of the Y-shaped connector form liquid perfusion passages commonly.

Description

technical field [0001] The invention relates to a medical device, in particular to a multipurpose ureteroscope balloon guide wire, which is suitable for ureteroscope technology. Background technique [0002] Ureteroscopy refers to various operations such as ureteral and renal tissue biopsy, lithotripsy, electrocautery, and internal incision of ureteral stenosis by placing an endoscope through natural human passages such as the urethra and bladder. It is mainly used to treat stones, polyps or strictures in the middle and lower ureter, and can also be used to diagnose diseases such as renal pelvis and ureteral tumors. Ureteroscopic surgery has no incision, less trauma, and quick recovery, so it is favored by doctors and patients, and it has played an increasingly important role in the treatment of ureteral diseases, especially ureteral calculi. [0003] At present, in the domestic clinical operation of ureteroscopy or surgical operation of ureteroscope into the ureter, the fo...
