Problems solved by technology

[0003] Due to the high precision requirements for medical devices in the process of using the slit lamp for ophthalmic examination, the patient's head and eyes must be fixed to facilitate the doctor's observation. The forehead interference plate guides and fixes the patient's head. It has a limited limiting effect on the patient's head. Many patients are prone to shift during the examination process. At the same time, the existing fixing seat is inconvenient to adjust and cannot be well matched with different heights and head shapes. patient

Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the embodiments given in the accompanying drawings.

[0023] refer to Figure 1-6 As shown, the slit lamp head position fixing device includes a head fixing frame, a chin rest 2 and a forehead interference plate 3, the head fixing frame includes two vertical poles 1, and the chin rest 2 is arranged horizontally on the two vertical poles 1 Between them, the forehead interference plate 3 is horizontally arranged on the front ends of the two vertical rods 1. The chin bracket 2 and the forehead interference plate 3 correspond to the positions of the chin and the forehead respectively. The chin bracket 2 can be an existing one in the prior art. The bracket structure is made of plastic material, and the middle position is recessed downward to form a place for the chin to be placed. The middle of the forehead collision plate 3 is bent forward to form an arc surface suitable for the shape of the...

Abstract

The invention discloses a head position fixing device for a slit lamp, which includes a head fixing frame, a chin bracket and a forehead interference plate. It is set at the front end of the two poles, the chin support seat and the forehead interference plate correspond to the positions of the chin and the forehead respectively. It also includes a fixed plate and a mounting plate on the top of the head. The horizontal frame of the mounting plate is set above the vertical pole. The chin bracket is slidingly connected with the vertical pole. The vertical pole is provided with a control mounting plate, a forehead interference plate and a lifting device for lifting the chin bracket up and down. The lifting device is provided with a switching mechanism. The switching mechanism is used for switching the control mounting plate, The forehead collision plate and the chin support fit the patient's head more closely, and the lifting device and the switching device are combined to facilitate the control and switch between multiple parts. The patient's position will not change greatly, making the detection result more accurate.

Description

technical field [0001] The invention relates to the field of medical equipment, and more specifically relates to a slit lamp head position fixing device. Background technique [0002] Slit lamp microscope 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. . [0003] Due to the high precision requirements for medical devices in the process of using the slit lamp for ophthalmic examination, the patient's head and eyes must be fixed to facilitate the doctor's observation. The forehead interference plate guides and fixes the patient's head. It has a limited limiting effect on the patient's head. Many patients are prone to shift during the examination process. At the ...
