Description

Neurosurgery is clinical with wear-type magnifying glass

Technical Field

The invention relates to the technical field of head-wearing magnifying glasses, in particular to a head-wearing magnifying glass for neurosurgery clinic.

Background

The head-wearing magnifier is made of high-quality glass and environment-friendly plastic, is convenient for workers to use by utilizing a head-wearing design, and can be worn on the head.

In the medical field, doctors often use a head-mounted operation magnifier to magnify the visual field of the head-mounted operation magnifier for patients to perform various medical treatment, operations or related disease diagnosis; since the size and detail of the patient's clinical signs or the appearance of any part are limited by the doctor's own eyesight, the image-magnifying optical device can help the physician to perform various medical actions

At present, when the existing medical magnifier is used, the magnifier needs to be used for operation assistance, however, when the existing medical magnifier is used, a doctor can adjust the distance between the magnifier and eyes according to the doctor, then, the distance between the magnifier and an object is adjusted, the optimal angle adjustment is realized, so that the medical magnifier is suitable for the optimal use of the operation, and when the medical magnifier is used, because the doctor performs the operation for a long time, and simultaneously keeps a posture, the fatigue phenomenon is easy to occur, therefore, the doctor can randomly adjust the head position of the doctor and simultaneously performs the rest of the eyes, when the doctor performs the short rest in an operation gap, on one hand, the magnifier is still positioned at the eyes of the person, and the doctor is not convenient to turn over the magnifier under the condition that the hand carries gloves, on the other hand, after the short rest or the movement, there is still a need to maintain the original position, thereby increasing the operation intensity of the doctor, and for this reason, we propose a neurosurgical clinical head magnifying glass.
