[0037] As Figures 1 to 3 shown, the active medical device provided by the present application, wherein the body 100 includes a first housing 1 and a second housing 2. The first housing 1 and the second housing 2 cooperate to form a complete appearance, the functional device 3 is arranged inside the first housing 1 or the second housing 2, the functional device 3 is used to realize the various functions of the active medical device, and the first housing 1 and the second housing 2 provide protection for the functional device 3.

When there are multiple functional devices 3, the functional devices 3 can be distributed in the first sealed cavity 11 or the second sealed cavity 21.
[0039] A through groove S is concavely provided on the upper part of the first housing 1 and / or the second housing 2, and the through groove S is in a through shape along the first direction X; the first housing 1 is movably connected to the second housing 2, and the notch of the through groove S is closed to enclose and form a heat dissipation channel T that is through along the first direction X.
[0040] Optionally, through grooves S are provided on the upper parts of both the first housing 1 and the second housing 2, and the through groove S of the first housing 1 is arranged opposite to the through groove S of the second housing 2 and encloses to form the heat dissipation channel T.
[0041] During the process of the cooling fluid flowing through the heat dissipation channel T, heat exchange can be carried out with the first housing 1 and the second housing 2 respectively, so as to cool down the functional device 3 located inside the first sealed cavity 11 and the second sealed cavity.

That is, when the functional device 3 is arranged in the first sealing cavity 11, it contacts the position on the inner surface of the first housing 1 corresponding to the heat dissipation channel T. When the functional device 3 is arranged in the second sealing cavity 21, it contacts the position on the inner surface of the second housing 2 corresponding to the heat dissipation channel T, so as to reduce the heat transfer path between the functional device 3 and the heat dissipation channel T and further improve the heat dissipation efficiency.

[0052] Specifically, the first joint is located on the first side of the body 100 along the second direction Y, and the first side of the first housing 1 along the second direction Y is rotatably connected to the first side of the second housing 2 along the second direction Y; the first direction X is perpendicular to the second direction Y. By rotating the first housing 1 or the second housing 2, the side surface of the first housing 1 and / or the second housing 2 formed with the through groove S can be exposed. At this time, the staff can clean and disinfect the inside of the through groove S by wiping, removing bacteria and dust existing in the heat dissipation channel T.
[0053] Optionally, for the active medical device provided by the present application, wherein, the second joint is located on the second side of the body 100 along the second direction Y, and the second side of the first housing 1 along the second direction Y and the second side of the second housing 2 along the second direction Y are detachably connected by a locking member. When it is necessary to wipe and disinfect the through groove S, the locking member can be opened so that the first housing 1 can rotate relative to the second housing 2 to expose the through groove S. After the wiping and disinfection are completed, the locking member can be locked to fix the relative positions of the first housing 1 and the second housing 2.
