Medical field is the utility model is related to, more precisely, being that a kind of C-arm X-ray machine arm pipe shaft balancing that is used for is examined
Survey component.
Background technology
C-arm X-ray machine produces the bulb of x-ray as the term suggests the equipment has the frame of c-type, and the image for gathering image increases
Strong device and ccd video camera, and the work station composition of image procossing.The work such as the radiography being mainly used in various operations, photography.
Also distinguish in addition with other x-ray devices such as：U-shaped arm, G shape arms etc..
C-arm X-ray machine arm pipe axle is the mechanical rotating shaft for controlling C-arm entirety posture, and the posture difference of C-arm acts on arm
The power of pipe axle is difference, and the whole machine balancing state of C-arm can be perceived by the stress of detection arm pipe axle, is advantageous to c-type
The pose adjustment of arm.But the measurement accuracy for being currently used in arm pipe shaft balancing detection components need to be improved.
Utility model content
The utility model is mainly to solve the technical problem present in prior art, is used for C-arm X-ray so as to provide one kind
Horn pipe shaft balancing detection components.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：
One kind is used for C-arm X-ray machine arm pipe shaft balancing detection components, includes a sensing egative film and a sensing top flat, sense
Egative film is answered to be connected with the both sides for sensing top flat by a pair of shell fragments, sensing egative film is provided with a spacing catch, senses and is set on top flat
There are a pair of stators, stator is used to detection components being fixed on arm pipe axle, senses and is additionally provided with a pair of piezo-resistances on top flat
Piece, the edge for sensing top flat are provided with multiple welding electrodes, and the medial surface of shell fragment is provided with a left piezoelectricity ceramics and a right piezoelectricity ceramics,
The left piezoelectricity ceramics, right piezoelectricity ceramics and a pair of piezoresistive wafers electrically connect with welding electrode.
As the utility model preferred embodiment, described spacing catch and sensing egative film are integrally formed.
