Auxiliary arm bracket for slit lamp

Abstract

The invention discloses an auxiliary arm bracket for a slit lamp, which relates to the technical field of medical instruments and comprises a telescopic bracket assembly, a bracket assembly, a flexible force storage assembly, a displacement sensor, an arm support and the like. The telescopic bracket assembly can achieve multi-gear pose adjustment through cooperation of a clamping pin arranged on a locking sleeve and a clamping hole formed in a second gear, and the adjustment is coarse adjustment. The telescopic bracket assembly can be quickly unfolded and folded; a first motor and a first lead screw are arranged on the telescopic bracket assembly, so that the pose adjustment of the bracket assembly can be realized, and the adjustment is fine adjustment; the flexible force storage assembly utilizes the force decomposition principle, and a large force storage value can be achieved; the flexible force storage assembly and the bracket assembly are combined according to the lever principle, and self-adaptive lifting of the arms of a doctor can be achieved; the flexible force storage assembly can automatically adapt to doctors with different weights; and the displacement sensor can realize dynamic tracking of the bracket assembly on the jaw bracket of the slit lamp .

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a slit lamp auxiliary arm bracket. Background technique [0002] The slit lamp microscope (referred to as "slit lamp") is an essential and important instrument for eye examination. The slit lamp microscope is composed of an illumination system and a binocular microscope. It can not only observe superficial lesions very clearly, but also can adjust the focus and the width of the light source to make an "optical section" so that lesions in deep tissues can also be clearly displayed. . Its structure is mainly composed of two parts, namely "slit lamp" and "microscope". In order to facilitate the slit light source to irradiate various parts of the eye from different angles, and the microscope to observe the eye from different angles, both the slit lamp and the microscope are required to have sufficient left and right swing angles mechanically. In addition to the above-m...

Problems solved by technology

[0003] During the use of the slit lamp, the doctor needs to control the slit lamp with one hand, and at the same time, the other hand performs some necessary operations on the patient. During the operation, the arm is in a suspended state. If the examination takes a long time, the doctor's arm will become sore , increased shoulder discomfort, slow examination, reduced work efficiency, and reduced patient experience
