Embodiment approach 1
[0042] (Configuration of Internal Surveillance Camera System)
[0043] figure 1 It is a schematic diagram showing the configuration of the internal monitoring camera system according to the first embodiment. like figure 1 As shown, the internal monitoring camera system 1 includes: an imaging device including a camera unit 11 (imaging unit), a camera-side cable 12 (first cable) and a camera-side cable connector 15a (first connector) connected thereto; Camera support pipe 13 (support pipe); device-side cable connector 15b (second connector); device-side cable 16 (second cable); and a control system including a camera unit control device 17 and a display 18 (display device) . In addition, the cable connectors may be collectively referred to as "cable connectors 15" hereinafter.
[0044]The camera support tube 13 passes through the inside of a cannula 31 (holding tube) punctured through the abdominal wall, and one end thereof is introduced into the body. The camera unit 11 fo...
Embodiment approach 2
[0103] In Embodiment 1, the cannula and the camera support tube were made independent, but the camera support tube may have the function of a cannula or a trocar. Although the description will be given below in the case of a cannula, it goes without saying that the same applies to the case of a trocar. Figure 7 (a) is a perspective view of the camera support tube of Embodiment 2, Figure 7 (b) is its cross-sectional view. like Figure 7 (a) As shown in (b), the camera support tube 35 is the same funnel shape as the cannula, and one end (body outside) is thicker than the other end (body inside), and at the other end (body inside) , a locking hole 123 (recess) is provided. In addition, the locking hole 123 can be as Figure 7 (a), Figure 7 As shown in (c), it is arranged on a part (at least 2 places) of the outer periphery of the camera support tube 35, and it may also be as Figure 7 As shown in (e), at the end of the camera support tube 35, a groove-shaped concave port...
Embodiment approach 3
[0122] In Embodiments 1 and 2, the camera support pipe is a circular pipe (circular in cross section), but it is not limited thereto. Figure 10 (a) is a perspective view of the camera support tube of Embodiment 3, Figure 10 (b) is its cross-sectional view. like Figure 10 (a) As shown in (b), the camera support tube 51 may be a quadrangular prism tube (rectangular in cross section). A locking hole 123 (recess) is provided at one end (body inside) of the camera support tube 51 . Figure 10 (c) is a cross-sectional view of a support tube joint portion of a camera unit used in Embodiment 3. FIG. like Figure 10 As shown in (c), the support pipe joint portion 114 of the camera unit has a hole structure with openings at four corners, and locking claws (protrusions) 23 are provided on the inner wall thereof. Then, by inserting the end portion (body inside) of the camera support tube 51 into the support tube joint portion 114, the locking claw 23 fits into the locking hole 123...
