Problems solved by technology
[0005] A part of the lens barrel of the TTL type surgical loupe is combined with the eyepiece, and the structure is compact, small and light. However, the lens barrel of the existing TTL type surgical loupe is embedded in the eyepiece, and the lens barrel and the eyepiece can only be bonded with special glue. , must be customized according to the eye structure and physiological parameters of each user, and can only be handmade by experienced technicians. Adjustment, so any small precision deviation in the process of measurement and production will lead to inconsistencies in pupil distance, focus, optical axis and other parameters, making it unusable

The invention discloses an invisible hinge for operating magnifying glass, which is characterized in that: the invisible hinge mainly comprises a backer (1), a left wing (2) and a right wing (3), wherein the backer (1) is in sliding connection with the left wing (2) or the right wing (3); the left wing (2) is in sliding connection with the right wing (3); the left wing (2) is provided with a leftsupport arm (23); the tail end of the left wing (2) is connected with a left lens barrel support ring (24) provided with a left lens barrel; the right wing (3) is provided with a right support arm (33); and the tail end of the right support arm (3) is connected with a right lens barrel support ring (24) provided with a right lens barrel. The invisible hinge for the operating magnifying glass has long working distance; the clear, bright and wide visual field provides convenience for precision work; different multiplying powers and working distances are provided for users; and the invisible hinge has the advantages of convenient loading and easy adjustment.
Description
[0001] The application in this case is an application for both a utility model patent and an invention patent for the invention and creation on the same day. The name of the invention and creation is an invisible hinge for a surgical magnifying glass. technical field [0002] The invention relates to the field of optical instruments, in particular to an invisible hinge for a surgical magnifying glass, which is used to support and fix the surgical magnifying glass. Background technique [0003] Surgical magnifying glass (English loupes) adopts the original optical stereo convergence observation technology, which converges the observer's binocular line of sight in the narrow cavity of the lens barrel to produce a bright and enlarged three-dimensional field of view, providing a unique stereoscopic deep scene for inspection and treatment . Surgical magnifying glass integrates the functions of commonly used instruments in ENT, such as reflective bowl mirror, headlight and binocul...
