Straight-rod non-separable hard-tube endoscope with infinite visual angle

Abstract

The invention relates to the technical field of medical imaging equipment, and discloses a straight-rod non-separable hard-tube endoscope with infinite visual angle, wherein the endoscope includes anendoscope body; one side of the endoscope body is fixedly provided with an eyepiece tube, the other side of the endoscope body is fixedly provided with an outer mirror tube, and one end of the outer mirror tube is fixedly provided with an endoscope lens. According to the straight-rod non-separable hard-tube endoscope with infinite visual angle, through arrangement of a magnetic ring and an electromagnetic coil, a reflecting mirror plane can rotate 360 DEG independently without rotation of the whole structure of the endoscope. Compared with a conventional endoscope, in the case of indetermination of specific orientation of a sick body of a patient, the endoscope with different visual angles is not needed to be continuously selected, or the best observation visual field and clarity are obtained by rotating the endoscope, the diagnostic efficiency of medical staff when the endoscope is used can be effectively improved, the injury to the patient is reduced, and the use effect is good.

Description

technical field [0001] The invention relates to the technical field of medical imaging equipment, in particular to a rigid tube endoscope with an inseparable straight rod and infinite viewing angle. Background technique [0002] Endoscope is an important instrument for people to peep into the internal organs of the body, and the hard tube endoscope is mainly used for the diagnosis and treatment of the natural orifice of the human body or through the puncture of the orifice, because it is less traumatic to the patient. And the recovery is fast, and the imaging resolution is high, and the operation is convenient, and it is widely used in various fields. [0003] However, the viewing angles of all models of existing rigid tube endoscopes are fixed. When the specific position of the patient's body is uncertain, it is impossible to choose a suitable endoscope, and it is necessary to constantly choose endoscopes with different angles of view. , or by rotating the endoscope to obt...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides a rigid tube endoscope with an inseparable straight rod and infinite viewing angle, which can flexibly adjust the viewing angle of the lens, does not need to replace different types of endoscopes or the whole body of the rotating endoscope, and has high diagnostic efficiency. , Reduce the harm to the patient, the advantages of better use effect, solve the problem that the observation angle of view of all models of the existing rigid tube endoscope is fixed, and it is impossible to choose when the specific position of the patient's body is uncertain. For a suitable endoscope, it is necessary to continuously select endoscopes with different viewing angles, or to obtain the best observation field of view and clarity by rotating the endoscope, so that the efficiency of using the endoscope for diagnosis Lower, while increasing the pain and discomfort of the patient, causing greater harm to the patient, and poorer use effects
