Technical Field

The invention relates to a miniature endoscope, in particular to a miniature endoscope with an image stabilizing function and an instrument comprising the same.

Background

The existing various endoscopes or miniature endoscopes generally do not have an image stabilizing function, namely, when an operator rotates a lens, a displayed image deflects along with the rotation of the lens, the rotation direction of the displayed image and the rotation direction of the lens are opposite, a doctor does not have a sense of direction in the operation process (the left side seen on a screen is possibly not the left direction), great obstacles are caused to the doctor in the operation process, great difficulty is brought to precision operation of departments such as neurosurgery and the like, and meanwhile great harm is easily brought to patients due to misoperation of the doctor.

Disclosure of Invention

In order to solve the technical problems in the prior art, the invention discloses a miniature endoscope with an image stabilizing function, a brain puncture needle comprising the endoscope and an instrument applied to endoscopic surgery in various departments such as the abdominal cavity, the gynecology, the ear, the nose, the throat and the like.

The technical scheme disclosed by the invention is as follows:

a miniature endoscope with image stabilization function comprises a light-transmitting lens, a light source, a camera module, a tube shell, an azimuth angle detection device, a signal conversion device, a signal processing device and a display device; the light-transmitting mirror is arranged at one end of the tube shell; the light source and the camera module are sequentially arranged in the tube shell; the light emitted by the light source can pass through the light-transmitting mirror; the azimuth angle detection device is fixedly arranged on the outer ring of the tube shell and is used for detecting the rotation angle and the azimuth of the miniature endoscope; the azimuth angle detection device and the camera module are connected with the signal conversion device, the signal conversion device is connected with the signal processing device, the signal processing device adjusts the image deflection angle to realize the image stabilization, and the display device displays the stabilized image.

As a further technical scheme, the camera module and the light-transmitting mirror form a plurality of mounting grooves, and a light source is mounted in each mounting groove.

As a further technical scheme, the light source is arranged along the circumferential direction of the light-transmitting mirror.

As a further technical scheme, the camera module and the signal conversion device are in signal transmission in a wired or wireless mode.
