Description

Endoscope mirror positive marking structure

The invention relates to the marking of an endoscope, in particular to a lens positive marking structure of an endoscope.

US Patent No. 6,189,574 discloses a flexible tube for endoscope, wherein the flexible tube (Fig. 1) is extendable into a body cavity of a human body. The flexible pipe has a flexible sheath (Fig. 13), and a protruding striation (Fig. 14) is formed on the flexible sleeve, and the user touches and recognizes the Axial ribs to indicate the insertion position.

The axial rib is convenient for the user to touch to adjust the position. Since the flexible tube can extend into the body cavity of the human body and flexes with the body cavity of the human body, the angle of the flexible tube changes greatly, so the shaft Identifying the ridges results in loss of accuracy, and the endoscope is not directly guided by the axial ribs into a forward photographic design.

The main purpose of the present invention is to provide a forward direction marking structure of an endoscope, corresponding to the camera lens when the labeling member is located above at least one of the camera lens group, the flexible tube, the rigid tube or the grip. Above the image of the group photography, that is, the camera lens group is a positive camera for the convenience of operation.

According to the present invention, a lens forward marking structure of an endoscope includes: a camera lens group for capturing images; and a configurable flexible tube with a front end fixing The camera lens assembly; a rigid tube having a rear end fixed to the rear end of the flexible tube; and a grip fixed to the rear end of the hard tube; wherein the camera lens group, the configurable flexible tube, the When the hard tube and the grip are rotated, the rotation angle is uniform, and at least one of the camera lens group, the configurable flexible tube, the hard tube or the grip is provided with a labeling member, and the hard tube is horizontally placed The indicator member is located above the at least one of the camera lens group, the configurable flexible tube, the rigid tube or the grip, corresponding to the image captured by the camera lens group.

Thereby, the marking member of the present invention is located above the at least one of the camera lens group, the configurable flexible tube, the rigid tube or the grip, and is corresponding to the image of the camera lens group, that is, The camera lens group is a forward camera for the convenience of operation.

In order to explain in detail the technical features of the present invention, the following five preferred embodiments are described with reference to the following drawings, wherein: as shown in FIGS. 1 to 2, the first preferred embodiment of the present invention provides The lens forward marking structure 100 of an endoscope is mainly composed of a camera lens group 21, a shapeable flexible tube 31, a rigid tube 41 and a grip 51, wherein: an imaging lens group 21 is used. To capture an image.

A fixed flexible tube 31 is fixed to the front end of the imaging lens unit 21. In the first preferred embodiment, the shapeable flexible tube 31 is a snake neck tube.

A rigid tube 41 has a front end fixed to the rear end of the sizable flexible tube 31. In the first preferred embodiment, an indicator member 42 is longitudinally colored along the outer edge of the rigid tube 41.

A grip 51 has a front end fixed to the rear end of the hard tube 41.

Wherein, the imaging lens group 21, the flexible tube 31, the rigid tube 41 and the grip 51 rotate at an angle of rotation. When the rigid tube 41 is horizontally placed, the indicator 42 is located at the hard Above the tube 41, above the image photographed by the image pickup lens group 21, that is, the image pickup lens group 21 is forward photographed.

The structure of the first preferred embodiment of the present invention has been described above, and the state of use of the first preferred embodiment of the present invention will be described next.

Referring to FIG. 1 , first, the indicator member 42 of the hard tube 41 faces upward, so that the camera lens group 21 is forwardly photographed, and then the shapeable flexible tube 31 is bent into a predetermined photographing angle. The camera lens group 21 is still in the forward direction, and the shapeable flexible tube 31 maintains the bent shape except for re-bending the shapeable flexible tube 31, as shown in FIG. 2, and then the image pickup lens The group 21 extends into the interior of the implement. During the image capturing process, as long as the indicator 42 is maintained upward, the camera lens group 21 can be ensured to be in the forward direction for the user to facilitate the photographing operation inside the implement.

As can be seen from the above, the achievable effect of the present invention is that the improvement of the forward photography of the camera lens group 21 must be carried out by transmitting the image to a display (not shown) or a screen (not shown). It is confirmed whether it is a positive photography, and during the shooting process, it is also necessary to repeatedly adjust and determine the shooting angle of the camera lens group 21 through a display (not shown) or a screen (not shown). Whether it is correct, and thus causes troubles in use, and solves the prior art that the angle of the flexible tube varies greatly due to the flexible tube extending into the body cavity of the human body, and therefore, the axial rib reinforcement of the conventional use The problem of loss of accuracy is caused.
