Auxiliary stress mechanism and checking device comprising same

Abstract

The invention discloses an auxiliary stress mechanism and a checking device comprising same. The auxiliary stress mechanism can be applied to the checking device which is provided with an operating lever and regulates an operation table through the operating lever; a first stress surface and a second stress surface are arranged at the outer side of an inner stress part; a third stress surface and a fourth stress surface are arranged at the inner side of an outer stress part; a first bent hand accommodating position and a second bent hand accommodating position are formed between the inner stress part and the outer stress part, so that a direct stress part is provided to an operator; the operator can extrude the first stress surface, the second stress surface, the third stress surface or the fourth stress surface by a single hand, so that the operation table moves in front, rear, left and right directions, and the movements in the directions are combined to obtain a required movement amplitude. In a movement regulating process, required regulating force is remarkably reduced because of stress points, so that the auxiliary stress mechanism is time-saving, labor-saving, easy to operate and control, and convenient for the operator to quickly grasp regulating skills.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an auxiliary force-receiving mechanism and an inspection device including the auxiliary force-receiving mechanism. Background technique [0002] When physicians and other examiners perform local imaging inspections in ophthalmology and other parts, they often need to manually adjust the inspection device or key parts of the device in four horizontal directions for large and small movements, which are hereinafter referred to as large adjustments and fine adjustments. For example, Japan's Topcon TRC-NW8 non-mydriatic fundus camera, the traditional ophthalmic inspection device is generally equipped with a joystick structure, which can realize the needs of large adjustment and fine adjustment. The joystick of this type of device integrates the major adjustment and fine adjustment of the movement. Although the related needs of the movement adjustment have been realized, it often require...

Problems solved by technology

[0003] It is the joystick that integrates the two mobile functions into one structure, which not only makes it difficult for beginners to achieve the ideal goal in a short period of time, but also difficult to promote, and the actual mobile operation is also time-consuming and laborious.
