Description

Tissue exploration mirror

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to tissue exploring mirror.

Background

With the advancement of medical device technology, the exploratory mirror has become a medical device necessary for the current hospital. However, the conventional probe lens can be used only in a liquid phase and a gas phase, and cannot be used between solid-phase tissues, particularly in the brain parenchyma. Secondly, the front end and the rear end of the existing endoscope are required to be provided with optical lenses in the using process, the rear end is provided with a CMOS photosensitive element and a rear circuit continuation board for image acquisition, and the images are transmitted to a display at the far end through a cable for image display. The weight of the rear end of the endoscope is heavier and far greater than that of the front end of the endoscope, the operation is inconvenient, the head is light, the rear end is heavy, the operation hand feeling of a doctor is seriously influenced, and the operation is particularly obvious in the intracranial operation of neurosurgery.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the aforesaid not enough, provide one kind and can explore in the puncture between solid-state tissue, need not optical lens and image acquisition device, the visual tissue of direct bore hole explores the mirror.

Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:

as shown in fig. 1 and 2, a tissue exploring mirror, the mirror body comprises a reducing imaging optical fiber 1, the imaging, transmission and display of images are realized by the reducing imaging optical fiber, the head end 11 of the mirror body is of an outward convex curved surface structure, the top end of the reducing imaging optical fiber 1 forms the middle part of the curved surface structure, the top end of a light guide optical fiber 2 forms the outer edge of the curved surface structure, the mirror body comprises a light source interface 3, a light guide optical fiber 2 is arranged in a lens cone, and the light guide optical fiber 2 is arranged on the circumference close to the inner wall of the lens cone; the reducing imaging optical fiber 1 is positioned in a circular cavity enclosed by the light guide optical fiber 2, and the light guide optical fiber and the reducing imaging optical fiber extend in the same axial direction.

The rear end face 12 of the mirror body is an image amplification display end face, the end face and the axis of the mirror body form a certain included angle, and the outer surface of the mirror body is provided with scales.

The tissue exploration mirror can puncture and explore between solid tissues, is suitable for intra-tissue exploration, and is particularly suitable for intra-brain tissue exploration. When the brain tissue is punctured and probed, the curved surface structure of the lens body head end 11 which is convex outwards directly contacts the tissue, so that the brain tissue can be prevented from being damaged; in the using process, light enters tissues contacted with the reducing imaging fibers through the light source interface 3 and the light guide fibers 2, the tissues to be observed become bright, images of the bright tissues contacted with the front ends of the reducing imaging fibers are transmitted to the rear ends through the middle parts of the reducing imaging fibers and are amplified and mapped to the image amplification display end faces in real time, naked eye observation is achieved, an electronic image conversion device is not needed behind the tissues, operation is greatly facilitated, and the orientation sense and hand feeling of a doctor are guaranteed to be clearer.

In addition, the top end of the reducing imaging optical fiber can be adopted to form a curved surface structure, the light guide optical fiber is arranged on the circumference close to the inner wall of the lens cone, and a distance is reserved between the top end of the light guide optical fiber and the top end of the reducing imaging optical fiber.
