A device for holding a file

Abstract

The invention relates to the technical field of medical instruments and provides an instrument for holding files. It includes: a hammering block, a main body, a handle, shrapnel, a slider and a hook; one end of the main body is provided with a hammering block, and the hook is composed of a hook 1 and a hook 2, and the hook 2 is located at The other end of the main body; the main body is connected to the handle through pin two, and the handle is connected to one end of the elastic piece through pin one; the other end of the elastic piece is connected to the slider and the said elastic piece through pin three hook 1; the main body is provided with a limiting structure. During the opening and closing process of the handle, the shrapnel is driven to stretch and deform, and the slider and the hook connected to it are driven to move along the limiting structure. The first hook and the second hook on the main body always move linearly in the same plane. The beneficial effect of the present invention is that: during the opening and closing process of the handle, the hook moves in one direction, which ensures the convenience and speed of clamping the file, saves operation time, and improves operation quality.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and more specifically relates to an instrument for holding a file. Background technique [0002] In artificial joint replacement surgery, a file is often needed to shape the medullary cavity. Therefore, the instrument for holding the file needs to have the functions of holding the file and completing reaming and removing the file. For example, the file handle used in Zimmer's reverse shoulder replacement surgery plays such a role. [0003] This type of tool in the prior art can already meet the requirements of normal shoulder joint replacement, shaping of the medullary cavity, and removal of the file. The handle can be opened and closed to drive the internal connecting rod, causing the hook to adduct and abduct, so as to achieve grip. The role of the file. However, the existing file handle still has the problem that it is not easy to hold the file. During the operation, the handle n...

Problems solved by technology

However, the existing file handle still has the problem that it is not easy to hold the file. During the operation, the handle needs to be opened, and then the two hooks of the file handle are inserted into the corresponding grooves of the file.

During the opening and closing process of the handle of the file, the hooks on the head are brought in and out. The actual trajectory of the two hooks does not move linearly in one direction, so that the two hooks are not in the same plane in the end. When clamping the handle of the file, the two hooks enter the interface of the file successively, which makes it very inconvenient to clamp the file
