Embodiment approach 1

[0092] refer to Figure 8 ~ Figure 13 The structure of the grip part according to this embodiment will be described.

[0093] Figure 8 It is an explanatory diagram about the optimum length of the grip. Figure 8 (a) and (b) are plan views showing the grip portion of an appropriate range of length, Figure 8 (c) is a plan view showing a grip portion shorter than the appropriate range, Figure 8 (d) is a plan view showing the grip part longer than the appropriate range.

[0094] Figure 8 The grip parts 22 shown in (a) to (d) all protrude from the camera housing 21 to the left and right directions of the paper (refer to Figure 8 The "protrusion direction" in (a)) has a circular arc shape when viewed from above.

[0095] also, Figure 8 The grip portion 22 shown in (a) and (b) is an example having an appropriate length of the grip portion 22, and the length of the grip portion 22 in the protruding direction is equal to the outer shape (the above-mentioned circle) constit...

Embodiment approach 2

[0114] In Embodiment 1, the rough planar (planar view) shape of the grip portion 22 was mainly described in detail, but the cross-sectional shape of the grip portion 22 (that is, the distribution of the thickness of the grip portion 22 ) also has a . A structure that makes it easy to rotate the camera unit 11 . Hereinafter, the structure (tapered structure) which made the grip part 22 into the shape which becomes thinner gradually toward the edge of the grip part 22 is demonstrated.

[0115] Figure 14 It is a diagram showing a comparison between an example in which the cross-sectional shape of the grip portion is a rectangle with a constant thickness and an example in which it is tapered. Figure 14 (a) is a figure which shows the state which gripped the grip part with the pliers in the example which set it as a tapered shape, Figure 14 (b) is a diagram showing a state in which the grip part is grasped with pliers in an example of a rectangular shape, Figure 14 (c) is an...

Embodiment approach 3

[0122] In Embodiments 1 and 2, the outline shape (planar view and cross-sectional shape) of the grip portion 22 was mainly described in detail, but it is also possible to provide unevenness on the surface of the grip portion 22 or change the material of the grip portion 22, so that A mechanism having an anti-slip function is added to the grip portion 22 . Hereinafter, an example in which a groove-shaped pattern is formed on the grip portion 22 will be described, but it is not limited to this as long as it has equivalent functions.

[0123] Figure 15 It is a figure which shows the example of the groove pattern of a grip part.

[0124] Figure 15 (a) is a figure which shows the example which formed the several bow-shaped groove in a grip part.

[0125] exist Figure 15 The grip portion 22 shown in (a) is formed with a plurality of grooves 50 . Each of the plurality of grooves 50 extends in a circular arc (in other words, arcuate) when viewed from above. Furthermore, none ...

Abstract

The purpose of the invention is to enable easy retrieval of an image-capturing unit from the inside of a body. When external force from forceps (33) is imposed, a grip portion (22) allows a camera unit (11) to be dislocated as the forceps (33) move while the orientation of the camera unit (11) relative to the forceps (33) is maintained. When external force other than from the forceps (33) is imposed, the grip portion (22) allows the camera unit (11) to rotate around a contact point (61) or allows the camera unit (11) to rotate while the contact point(61) is subjected to rotary movement.

Description

technical field [0001] The present invention relates to an in-vivo monitoring camera system including an imaging unit introduced into the body. Background technique [0002] Endoscopic surgery is a low-invasive surgery that performs examination or treatment without opening the patient's laparotomy. In endoscopic surgery, a treatment tool such as forceps and an endoscope are respectively introduced into a patient's body cavity. The operator captures the image of the tip portion of the treatment tool inserted into the body cavity within the observation field of the endoscope, and performs the treatment while observing the treatment state of the treatment tool on the affected part through the endoscope. In endoscopic surgery, a treatment tool and an endoscope are introduced into a body cavity through a barrel that punctures a body wall (for example, abdominal wall) of the patient's abdomen or the like. In addition, the barrel is a so-called tubular member called a trocar. ...
