Abstract
The utility model provides a computer controlled display (CCD) camera system adjusting device of a three-dimensional endoscope. The CCD camera system adjusting device of the three-dimensional endoscope comprises an adapter adjusting gear engraved with a spiral groove, a focal distance gear and a focal distance gear adjusting rod. The adapter adjusting gear is sleeved outside an adapter and is screwed with an inner lens cone through the spiral groove, so that the front-back movement of the lens cone is achieved. The focal distance gear adjusting rod at the back end is connected with the inner focal distance gear of the three-dimensional endoscope to drive the adapter adjusting gear, so that the adjustment of the focal distance of the lens cone is achieved. The CCD camera system adjusting device of the three-dimensional endoscope has the advantage that the adjustment of the lens cone position and the lens cone focal distance of the CCD camera system can be performed outside the three-dimensional endoscope, so that the three-dimensional endoscope is convenient and fast to use.
Description
Technical field
This utility model belongs to the stereo endoscope field, especially relates to a kind of stereo endoscope CCD camera system adjusting device.
Background technology
Endoscope is more and more in the application of medical domain now, and along with the development of imaging technique and Computer Processing technology, two dimensional image far can not satisfy the requirement that people pursue stereoscopic vision.Especially at medical domain, the display system of operation usefulness is required day by day to improve, thereby promoted the research and development of stereoscopic endoscope system.
Stereoscopic endoscope system generally includes front end optical system and CCD camera system, image processing system, image display system.Wherein front end optical system and CCD camera system often are called stereo endoscope for short.The CCD camera system is comprised of two groups of photographic head.Wherein to mix adapter before separately the photographic head.Need adapter adjusted in order to reach suitable displacement and focal position before operation and in the operation and observe human body.At present stereo endoscope CCD camera system being regulated does not also have preferably method, and this has also limited practical clinical development of stereo endoscope.
Summary of the invention
Problem to be solved in the utility model provides a kind of stereo endoscope CCD camera system adjusting device, especially be fit to stereo endoscope CCD camera system move forward and backward and focal length is regulated.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Design a kind of stereo endoscope CCD camera system adjusting device, comprise adapter adjusting gear, focal length gear, focal length gear adjusting rod.The adapter adjusting gear is enclosed within the adapter outside.The focal length gear adjusting rod of stereo endoscope rear end links to each other with the inner focal length gear of stereo endoscope, drives the adapter adjusting gear.
Be carved with helicla flute above the adapter adjusting gear, can form turning effort with the lens barrel of endoscope inside.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, the lens barrel displacement of stereo endoscope CCD camera system and focus adjustment are convenient; Have simple in structure, the advantage such as processing cost is low, easy to use.
Description of drawings
Fig. 1 is stereo endoscope CCD camera system adjusting device sketch map of the present utility model
Among the figure:
1, adapter adjusting gear 2, focal length gear 3, focal length gear adjusting rod
The specific embodiment
As shown in Figure 1, this utility model comprises with spiral fluted adapter adjusting gear, focal length gear and focal length gear adjusting rod.
The work process of this example: the adapter adjusting gear is enclosed within the adapter outside, rotates by helicla flute and inner lens barrel formation, reaches the purpose that the control lens barrel moves forward and backward.The focal length gear adjusting rod of rear end links to each other with the inner focal length gear of stereo endoscope and drives the adapter adjusting gear, thereby forms the adjusting to the focal length of lens barrel.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to this utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
