Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with accompanying drawing, as Figures 1 to 3 As shown: the rapid bender for the tip of a coronary guidewire in this embodiment includes a finger cuff 1 that can be placed on a finger. The front end 1a of the finger cuff is conical and the rear end 1b is cylindrical. A thread 1c is provided on the outer peripheral surface of the sleeve 1, and the pitch of the thread decreases successively from the rear end of the finger sleeve to the front end of the finger sleeve. 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 bendi...

Abstract

The invention discloses a tip rapid bending device for a coronary artery guide wire. The device comprises a finger stall which can be sleeved on a finger. The front end of the finger stall is in a conical shape and the rear end is in a cylindrical shape. The outer peripheral surface of the finger stall is provided with threads. From the rear end of the finger stall, to the front end of the finger stall, the thread pitches of the threads reduce gradually. The tip rapid bending device for a coronary artery guide wire can accurately and rapidly bend tip angles of a coronary artery guide wire, and rationally controls bending angles of the guide wire tip according to differences of cardiovascular branch angles of a patient, so that the tip of the coronary artery guide wire can smoothly enter the specific 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...
