Description

Technical Field

[0001] The utility model relates to the technical field of guide wires, in particular to a disposable guide wire for the urinary tract. Background Art

[0002] Passive surgical instruments are instruments that do not require external energy supply during surgery and can be operated manually. Disposable urinary guidewires are a commonly used passive surgical instrument used in urinary tract surgery. The characteristics of disposable urinary guidewires are that they can reduce the risk of cross infection and avoid the spread of infection that may be caused by the reuse of instruments. At the same time, because they are disposable, they do not need to be cleaned and disinfected, saving surgical preparation time.

[0003] Since the guide wire is long, it needs to be wrapped and fixed. The existing guide wire is troublesome, time-consuming and labor-intensive to fix and remove. In addition, the existing guide wire has only one specification and cannot meet different needs, and has low applicability. Therefore, the utility model proposes a disposable urinary tract guide wire to solve the above problems. Utility Model Content

[0006] Preferably, the inner core of the guide wire is made of Nitinol alloy, and the front soft head is a soft head gradient setting.

[0007] Preferably, the fixing assembly includes a fixing frame and a fixing partition, and the fixing frame is a U-shaped frame.

[0008] Preferably, two fixed partitions are fixedly mounted on one end of the fixed frame, and three slots are formed between the two fixed partitions and the fixed frame.

[0009] Preferably, two rotating columns are fixedly installed in the three card slots, and a clamping plate is rotatably connected to the two rotating columns, and the clamping plate is an S-shaped plate.

[0010] Preferably, one end of the two clamps away from each other is fixedly connected with a spring, and one end of the spring away from the clamp is fixedly connected in the clamping slot.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] By providing a fixing assembly, the protection tube is spirally coiled, and the clamping groove formed by the fixing frame and the fixing partition is clamped on the protection tube. The protection tube squeezes the clamping plate to drive the clamping plate to rotate on the rotating column. Under the action of the spring, the spring drives the two clamping plates to clamp and fix the protection tube, which can achieve rapid fixation and avoid the need for more fixing pins for fixing, saving time and effort.

[0013] The head of the guide wire core is divided into two different specifications: straight head and elbow head. The straight head and elbow head can meet the needs of clinical physicians. The guide wire core is made of Nitinol alloy, which is not easy to bend, has the characteristics of anti-kink and strong support, and has a certain hardness, which is conducive to pushing and moving forward. The front soft head is a soft head gradient setting, which can achieve good flexibility and rebound effect, and has a good exploration effect. BRIEF DESCRIPTION OF THE DRAWINGS
