Description

Technical Field

[0001] This utility model specifically relates to the field of medical device technology, and more specifically to a tooling for grinding the end of a conveyor wire. Background Technology

[0002] In the field of medical devices, many delivery wires need to have their tips rounded to ensure that they do not cause scratches or other damage to tissues when used in the human body. For example, the smoothness of the tip of the guide wire used in cardiovascular interventional therapy directly affects the safety and effectiveness of the surgery. However, currently, after the delivery wire is cut, burrs or sharp points appear on the cut surface, which is not conducive to the subsequent processing and appearance quality of the product.

[0008] The guide block has a bottom surface that fits into the inner bottom surface of the groove. The bottom of the guide block has two sliding holes, and each sliding hole is fitted with a corresponding guide post. The top of the guide block has a wire threading hole.

[0009] Furthermore, as a preferred embodiment, the wire threading hole is coaxially arranged with the grinding head.

[0010] Furthermore, as a preferred embodiment, the wire-threading hole is composed of a wire-bundling section and a wire-guide section, wherein the inner diameter of the wire-bundling section is the same as the outer diameter of the conveying wire, and the wire-guide section adopts an inverted conical structure.

[0011] Furthermore, as a preferred embodiment, screws can be rotatably connected to the left and right inner walls of the slide groove, and the two guide posts are symmetrically arranged relative to the screws, with the screws being threadedly connected to the screw holes of the guide blocks;

[0012] A torsion head is provided on the right side wall of the adjusting distance platform, and the torsion head is fixedly connected to the screw.

[0013] This utility model adopts the above technology and has the following beneficial effects compared with the existing technology: The device of this utility model can round the end of the conveying wire through simple and convenient operation. Specifically, the guide block is moved to the rear using the distance adjustment table, leaving space for the customized grinding head to be installed on the clamp. The guide block is brought close to the grinding head using the distance adjustment table, and the distance is determined by adjustment to ensure that the conveying wire does not vibrate when it contacts the grinding head. Then, the motor is turned on and a suitable speed is selected. The employee passes the conveying wire through the guide block, and the end of the conveying wire is just able to be ground at the concave position in the center of the grinding head. After waiting for 30 seconds, the conveying wire is taken out, and the end of the conveying wire is rounded. Attached Figure Description
