Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of the embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without making creative efforts belong to the protection scope of the present invention.

Example 1

Referring to fig. 1 to 3, the present embodiment provides a guide wire rotation control device, which includes a rotating handle 1, wherein the rotating handle 1 is provided with a central guide wire hole 2 along a central axis thereof, the central guide wire hole 2 is used for accommodating a guide wire, a clamping member 4 is fixedly arranged in the central guide wire hole 2, and the clamping member 4 is used for clamping the guide wire in the central guide wire hole 2.

The swing handle 1 is composed of two swing handle segments 101 which are involutory, the two swing handle segments 101 are 1/2 of the swing handle 1, the two swing handle segments 101 are divided into two parts from the longitudinal direction of the swing handle 1, one side of each of the two swing handle segments 101 is hinged together through a hinge, and the other side of each of the two swing handle segments 101 is encircled into a whole through a fastener 3 to form the complete swing handle 1.
