Endoscopic image precision alignment device

Abstract

The invention discloses an endoscopic image precision alignment device, which comprises a standard definition pattern plate, a main body supporting frame, a hard-pipe endoscope and a data processing system, wherein the main body supporting frame comprises a standard definition pattern plate bracket, an endoscope bracket, a U-shaped bracket and a base; an ocular adjusting sleeve is arranged on the U-shaped bracket; one end of the hard-pipe endoscope is screwed into the ocular adjusting sleeve and the other end is arranged on the endoscope bracket; the data processing system is provided with a CCD (charge coupled device) interface lens; a CCD interface lens adjusting sleeve is arranged on one side of the CCD interface lens; a CCD is arranged on one side of the CCD interface lens adjusting sleeve; and a computer is arranged on one side of the CCD. The alignment device disclosed by the invention is skilful in structure and high in adjustment precision, and is capable of detecting the definition of an endoscopic optical system dynamically in real time by virtue of computer software, so as to improve alignment precision and efficiency; and image information is acquired through a CCD imaging system, and the image information is analyzed by virtue of a contrast formula, so as to dynamically and directly display a measurement result.

Description

technical field [0001] The invention relates to an adjusting device, in particular to an endoscope image precision adjusting device, which belongs to the technical field of optical system detection. Background technique [0002] Minimally invasive surgery has become the development direction of various fields of surgical medicine in the world today. Minimally invasive surgery is more and more widely used due to its many advantages such as less damage to patients, less pain for patients during surgery, and shorter recovery time after surgery. And the development of any minimally invasive surgery is inseparable from the hard tube endoscope, such as figure 1 shown. Rigid tube endoscope is welcomed by patients and surgeons for its advanced technology, convenient application, product diversification and specialization. At present, cystoscopy, hysteroscopy, laryngoscopy, sinusoscopy, laparoscopy, and arthroscopy have been widely used in county-level hospitals in my country. Gen...

Problems solved by technology

[0003] At present, the assembly inspection of the endoscope optical system mainly adopts the visual method, which has a great influence on the assembly result due to the diopter of the human eye, the illumination mode of the object under test, and the contrast of the object under test, and cannot be monitored quantitatively in real time. , leading to degradation of endoscopic image quality

At the same time, with the increase of working hours, visual fatigue and drowsiness will also lead to a decrease in product image quality
