DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an endoscope connecting device for detachably connecting a predetermined imaging device such as a TV camera and various adapters to an endoscope eyepiece.

[0002]

2. Description of the Related Art Generally, a mount for connecting an eyepiece (eyepiece) of an endoscope, for example, a rigid scope, and an external TV camera can be attached and detached to and from the eyepiece of the rigid scope with one touch. In addition, the configuration is such that the positioning accuracy for optical axis alignment is improved. As this type of endoscope connection device, for example, Japanese Patent Publication No. 1-52727 discloses an insertion port for inserting an endoscope eyepiece portion into a mount portion (connection device main body) of an imaging device such as a camera. An endoscope joint surface which is joined to the endoscope eyepiece in an abutting state is provided inside the insertion port, and the endoscope eyepiece is directed in the incident direction of incident light (the optical axis direction of the endoscope eyepiece). 2) shows a configuration in which the endoscope eyepiece is detachably connected to the mount of the imaging apparatus by being inserted into the insertion opening of the mount.

Further, a lock mechanism for preventing the endoscope eyepiece from coming off is provided on the mount side of the endoscope connection device of the above publication at the entrance side of the insertion port. The locking mechanism is disposed on the entrance side of the insertion port and protrudes and retracts into the movement trajectory of the endoscope eyepiece, and projects this locking member into the movement trajectory of the endoscope eyepiece. And an unlocking means for moving the locking member outwardly of the movement trajectory of the endoscope eyepiece against the urging force of the urging member. .

When the endoscope eyepiece is connected to the mount of the endoscope connection device, the endoscope eyepiece is inserted into the insertion port from the entrance side, and the mount is connected to the mount at a regular connection position. The endoscope eyepiece is brought into contact with the endoscope joint surface and joined. At this time, during the insertion operation of the endoscope eyepiece, the endoscope eyepiece comes into contact with the locking member of the lock mechanism,
Once the locking member is pushed out of the movement trajectory of the endoscope eyepiece against the urging force of the urging member of the lock mechanism,
At the time when the endoscope eyepiece is inserted to the proper connection position in the insertion port, the locking member projects into the movement trajectory of the endoscope eyepiece by the urging force of the urging member of the lock mechanism. The endoscope eyepiece is prevented from falling out of the normal connection position.

Incidentally, the lock of the lock mechanism is released by moving the locking member in a direction of retracting from the movement trajectory of the endoscope eyepiece unit against the urging force of the urging member by the lock releasing means. Further, the endoscope eyepiece can be removed from the insertion opening of the mount of the imaging device.

[0006]

However, in the above-mentioned conventional configuration, since a lock mechanism having a complicated configuration is used, the attachment and detachment between the mount unit of the imaging apparatus and the endoscope eyepiece unit is performed. There is a problem that the number of parts of the mechanism increases and the cost increases. Furthermore, there is a problem in that the structure of the attaching / detaching mechanism between the mount unit and the endoscope eyepiece unit of the image pickup apparatus is complicated, and the assemblability and maintainability are poor.

Further, since a clearance is small around the lock mechanism having a complicated structure and it is difficult to flow the cleaning liquid, it takes time and effort to clean the periphery of the lock mechanism when cleaning the mount after using the endoscope. There is such a problem.

The present invention has been made in view of the above circumstances, and an object thereof is to simplify the structure of a detachable mechanism between a mount section of an imaging apparatus and an endoscope eyepiece section,
It is an object of the present invention to provide an endoscope connection device capable of reducing the number of parts and improving the ease of assembly, maintenance, and cleaning.

A connection device main body provided with an endoscope joint surface, connected to the imaging device side, a locking member receiving portion provided in a portion of the connection device main body near the endoscope joint surface, and the eyepiece portion. A locking member that is detachably attached to the locking member, and a detachment that is provided on the locking member and that elastically engages and disengages with the locking member receiving portion to prevent the eyepiece from coming off. An endoscope connection device comprising a blocking element. At the time of connection work for connecting a predetermined imaging device to the endoscope eyepiece, the endoscope eyepiece is joined to the endoscope joint surface of the connection device main body, and a locking member is attached to the eyepiece. In a state in which the locking member is detachably mounted, the detachment preventing element of the locking member is elastically and detachably engaged with the locking member receiving portion of the connection device main body.
In addition, the engagement between the locking member receiving element of the locking member and the locking member receiving portion of the connection device body is released to separate the endoscope eyepiece from the imaging device. .
