Embodiment Construction
[0051] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.
[0052] refer to figure 1 , to describe the schematic configuration of the endoscope system.
[0053] The endoscope 30 of the endoscope system has a wireless unit 52 . The wireless unit 52 performs signal processing on the imaging signal of the subject to generate a video signal, and then converts the video signal into a wireless signal and transmits it. The wireless signal transmitted from the wireless unit 52 is received by the receiving antenna 67a. The receiving antenna 67a is connected to the processing device 31, and the processing device 31 converts the wireless signal into an image signal, and further performs image processing on the image signal. A video display device 32 is connected to the processing device 31, and the video display device 32 displays the video signal as a video. Furthermore, a computer 33 is connected to the processing device 31, and t...

An endoscope configured to be carried with a hand is characterized by comprising an insertion portion (34) extending in a longitudinally axial direction and including a distal end portion and a proximal end portion, and an operation portion (38) coaxially connected to the proximal end portion of the insertion portion (34) and extending in the longitudinally axial direction, the insertion portion (34) includes a bending portion (36) configured to be actuated to be bent, the operation portion (38) includes an axially directional grasp portion (40) extending in the longitudinally axial directionand configured to be grasped by an operator, a bending operation portion (46) provided on a more proximal end side than the axially directional grasp portion (40) and configured to operate the bendingportion (36) to be bent, and a widely directional grasp portion (53) provided on a more proximal end side than the bending operation portion (46) and configured to be grasped by an operator wherein at least a part of the bending operation portion (46) is located within a widely directional length of the widely directional grasp portion (53) with respect to a wide direction orthogonal to the longitudinally axial direction, and the widely directional grasp portion (53) includes a grasp part (53a, 53b) protruding farther toward one widely directional side than the bending operation portion (46).
Description
technical field [0001] The invention relates to a hand-held endoscope that can be held vertically and used horizontally. Background technique [0002] The endoscope has an insertion portion extending in a longitudinal direction and inserted into a body cavity. A bending portion capable of bending is provided at a front end portion of the insertion portion. The base end portion of the insertion portion is coaxially connected with the operation portion, which extends in the longitudinal direction and is operated by the operator. In the operation part, a grip part to be gripped by the operator is extended along the long-axis direction. In addition, in the operation part, a bending operation part for bending the bending part is provided on the proximal end side of the grip part. When using an endoscope on a recumbent patient, it is usual to hold the endoscope vertically and use it. That is, the grip portion is gripped with one hand, and the thumb of the one hand is placed on...
