Problems solved by technology

In the past, the bending of the tip of the guide wire was done manually by doctors based on experience. There was no special device that can quickly bend the tip of the guide wire, which made the angle of the guide wire bent not accurate enough, which increased the risk of surgery.

Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with accompanying drawing, as Figures 1 to 3 As shown: the mechanical control metal qualifier in this embodiment includes a finger cot 1 that can be placed on the finger. The front end 1a of the finger cot is conical and the rear end 1b is cylindrical. A thread 1c is formed on the circumferential surface, and the pitch of the thread decreases successively from the rear end of the fingertip to the front end of the fingertip. Specifically, the width of the groove of the thread 1c corresponds to the outer diameter of the guide wire. When in use, the bender of the present invention can be set on the index finger of the doctor's hand, then press the tip of the guide wire into the thread groove with the thumb of the hand, and bend the guide wire with the other hand to make the guide wire The wire is bent along the direction of the thread groove, and different bending angles can be obtained by pressing the...

Abstract

The invention discloses a mechanical angle fixer which comprises finger sleeves capable of being worn on fingers. The front end of each finger sleeve is in a conical shape, and the rear end of the finger sleeve is in a cylindrical shape. A thread is formed in the outer circumference of each finger sleeve, and the thread pitch of the thread from the rear end of the finger sleeve to the front end ofthe finger sleeve is sequentially reduced. The precise length and angle setting can be conducted on the tip end of a coronary artery guide wire through a mechanical control metal fixer, the bending length and angle of the tip end of the guide wire can be reasonably controlled according to the different branch diameters and angles of heart blood vessels of a patient, and then the tip end of the coronary artery guide wire can smoothly enter a designated branch blood vessel.

Description

technical field [0001] The invention relates to a medical device, in particular to a device capable of controlling the bending angle of the tip of a coronary guide wire according to actual needs. Background technique [0002] In recent years, percutaneous coronary angioplasty for stenotic and completely occluded coronary arteries has become one of the most effective means of treating coronary heart disease. Coronary guide wire is a tool that must be used in percutaneous coronary angioplasty. The stent can be delivered to the diseased blood vessel through the guide wire. If the guide wire is to be selected correctly and enter the branch blood vessel smoothly, it must be pre-installed. Bend the tip of the guidewire at an angle. In the past, the bending of the tip of the guide wire was done manually by doctors based on experience. There was no special device that could quickly bend the tip of the guide wire, which made the bending angle of the guide wire inaccurate and increas...
