Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a device for sliding a held endoscope for observing and recording deep inside the abdominal cavity.

[Conventional technology]

In a conventional endoscope, as shown in FIG. 5, an endoscope 100 is inserted into a patient, and a doctor observes the patient through an eyepiece 101 of the endoscope 100.

[Problem to be solved]

With such conventional means, the doctor must direct the endoscope 100 to point the tip at the desired affected area, and when the doctor holds the endoscope in place with one hand, various operations must be performed. could only be done with one hand. Therefore, various devices have been developed to hold an endoscope inserted into a patient in a predetermined position, and these devices are used to insert the endoscope 100 into a desired position and then hold the endoscope 100. Two methods have been considered: a method in which the endoscope 100 is fixed at a desired position with a device, and a method in which the endoscope 100 is fixed in advance to a holding device and then inserted into the patient. In both of these two methods, there is a method of observing from the eyepiece section 101 and a method of observing by projecting it on a display. In the method of fixing the endoscope 100 to a holding device in advance and inserting the endoscope 100 into the patient, there is a risk of inserting the endoscope 100 too far and damaging the internal organs. It was also difficult to extract 100 pieces easily.

Therefore, this idea was developed in such a way that the endoscope is held in advance and the held endoscope is inserted into the patient's body (in this case, it is shown on the display). An object of the present invention is to provide an endoscope slide device that does not cause any difficulty in insertion and removal operations.

[Means to solve the problem]

In order to achieve the above-mentioned object, this invention is constructed so that an endoscope is held in a holder part attached to one of a plurality of arms, and an arm that can be slid up and down among the plurality of arms and an arm that can be slid up and down. A pinion or rack is provided on the sliding side of the supporting arm or column, and/or the holder part and the arm to which this is slidably attached, and a rack or pinion is provided on the non-sliding side, and the pinion is engaged with the rack. The device is equipped with a switching means for regulating or permitting rotation of the rotor.

[Effect]

In this invention, when the holder part is attached to the arm that is inserted into the column and can be slid up and down, or to the distal end arm so as to be movable up and down, the endoscope can be moved up and down by rotating the pinion, and the endoscope can be lowered. Sometimes an endoscope is inserted into the patient's body. When removing the endoscope from the patient's body, the pinion can be rotated in the opposite direction to easily raise the holder portion or the vertically slidable arm. When fixing the endoscope at a desired insertion position, rotation of the pinion may be restricted using the switching means.

〔Example〕

Preferred embodiments of this invention will be described below with reference to the drawings.

In FIG. 1, one of the plurality of arms 2 to 5
The endoscope 1 is configured to be held in a holder part 6 attached to the holder part 6. The arms 2, 3, and 4 are rotatably connected by joints 7 and 8, respectively. The arm 4 can be slid up and down relative to the arm (post) 5. The endoscope 1 is held in a holder section 6, and images observed with the endoscope 1 are sent to a control section 9 and displayed on a display 10. In the embodiment shown in FIG. 1, the holder portion 6 is designed to slide. The details are as shown in Figure 2.
A rack member 13 on which a rack 12 is formed is slidably attached to a casing 11 fixed to the casing 11, and a pinion 14 is rotatably attached within the casing 11 by an operating shaft of an operating member 15. By rotating the operating member 15 having an operating shaft attached to the pinion 14, the rack member 13 having the rack 12 meshed with the pinion 14 slides along the axial direction of the casing 11. The rack member 13 is fixed to the holder part 6. A switching means 16 for regulating or permitting rotation of the pinion 14 is attached to the casing 11. A bolt is used as the switching means 16, and when the switching means 16 made of the bolt is pressed against the pinion 14, the pinion 14 is prevented from rotating and becomes locked, and the sliding of the rack member 13 and the holder portion 6 is stopped. It goes without saying that the means for slidably attaching the rack member 13 to the casing 11 is not limited to the concave-convex fitting shown in the drawings, but various sliding means such as dovetail fitting can be employed.

The holder part 6 includes a holder body 6A and a lid body 6B.
The cover body 6B is attached so that it can be opened and closed using the hinge 6C, and the cover body 6B is closed and the screw 6D is tightened.
is fixed to the holder main body 6A. Further, a bearing (not shown) is provided between the operating shaft of the operating member 15 and the casing 11 in order to ensure smooth rotation of the operating member 15. In addition, a cork, rubber, etc. is attached to the tip of the switching means 16, and this is always connected to the pinion 14.
It is also possible to apply a frictional force to the extent that the endoscope 1 does not fall when the operating section 15 is not operated.

In the embodiment shown in FIG. 3, the casing 11 is not attached to the arm 2, but a box 17 containing a pinion 14 is fixed to the arm 2, and a rack 12 that meshes with the pinion 14 in the box 17 is provided. The holder part 6 is shown fixed. Needless to say, the relationship between the rack 12 and the box 17 is such that the rack 12 is slidable relative to the box 17 by fitting the rack 12 into the box 17 so that the rack 12 does not separate from the box 17.

In the embodiment shown in FIG. 4, a rack 12 is formed in a part of the inner circumferential surface of an arm 4 that is vertically slidable, and a long hole 4A of a constant distance is formed along the axial direction. Insert the operating shaft of the operating member 15 attached to the arm (post) 5 into this elongated hole 4A, and
Set the pinion 14 so that it is located inside.
The pinion 14 and the rack 12 mesh with each other, and by rotating the operating member 15, the pinion 14
The arm 4 is slid by rotating the pinion 12 and moving the pinion 12 left and right in the drawing. The switching means 16 is provided on a flange portion 5A formed at the upper end of the arm (post) 5, and by tightening the switching means 16, the arm 4 is prevented from sliding, and by loosening the switching means 16, the arm 4 can be slid.

In the above-described embodiment, a case where the holder part 6 is slid up and down and a case where the arm 4 is slid up and down is explained, but either one or both may be used together. Furthermore, the number of arms is not limited to the illustrated embodiment, and it is also possible to configure the means for holding the endoscope 1 from a larger number of arms. In addition, each joint 7, 8
In this case, each arm is configured to be rotatable as shown in the direction of the arrow in FIG.

Furthermore, if the rotation of the pinion 14 is restricted by frictional force so that the sliding member remains stationary unless the operating member 15 is rotated, the operability will be further improved. .

〔effect〕

As explained above, according to this invention, the endoscope is held in a holder part attached to one of the plurality of arms, and the arm which can slide up and down among the plurality of arms and this A pinion or rack is provided on the sliding side of the supporting arm or column, and/or the holder part and the arm to which this is slidably attached, and a rack or pinion is provided on the non-sliding side, and the pinion is engaged with the rack. Since we have provided a switching means to restrict or allow rotation of the
The endoscope can slide smoothly and easily.
Furthermore, the switching means allows the slide to be easily locked and unlocked.
