The horizontal expansion degree set, also facilitates medical worker to be adjusted in real time.A connection piece 17 is further fixed in hand-held revolving part 16
And connect by the connector 17 with mobile bar 18, the hand-held rotation of revolving part 16 is simultaneously mobile to pass through connection with handle handle
Part 17 drives mobile bar 18 to move axially along handle, and mobile bar 18 moves through connecting rod 19 and opens arc expansion 2 level of block
Expansion, so by transmission parts horizontal expansion so that processing unit 3 out of vertical space that strut part it is horizontal remove and with vertebral bone face
Processor horizontal expansion operation is completed in contact.
In conjunction with Fig. 7, Figure 14 and Figure 16, the fixation auxiliary of a pair of setting symmetrical above and below is extend horizontally away at 1 processing end of handle
20, fixed auxiliary 20 is located in the vertical space for strutting part, and through-hole 21 is offered on fixed auxiliary 20, and a pair of of arc expands block 2
End pass through pin shaft and the through-hole 21 of fixed auxiliary 20 is connected to horizontal expansion support end, with mobile bar 18, connecting rod
The horizontal expansion of arc expansion block 2 is realized in 19 cooperations.
In order to improve transmission efficiency, selection transmission parts are transmission chain 22, the arc of transmission chain 22 and arc expansion block 2
Outside face contact is also coaxially provided with the first sprocket wheel 23 engaged with transmission chain 22 at horizontal expansion support end.
Shown in Figure 18, processing unit 3 includes multiple processing units, and processing unit includes sleeve 24 and is symmetricly set on
The processing knife 26 at 24 both ends of sleeve, sleeve 24 is vertically embedded to be fixed on transmission chain 22, has a mobile sky inside sleeve 24
Between 25, processing knife 26 cutter head protrude from sleeve 24 setting, processing knife 26 knife handle be arranged in the mobile space 25 of sleeve 24,
Elastic component 27 is connected between processing knife 26.When processor is in off working state, vertical spreading mechanism remains retracted state,
It struts part and acts on the cutter head for handling knife 26 and make 27 forced compression of elastic component, handle movement of the knife handle in sleeve 24 of knife 26
Moved axially along sleeve 24 in space 25 so that processing 3 is placed in the vertical space for strutting part, particular state together referring to
FIG. 1 to FIG. 3.When processor is in running order, processing unit 3 is horizontal out of vertical space that strut part to be removed, and handles knife 26
Knife handle by 27 resilient force of elastic component in mobile space 25 along sleeve 24 move axially to processing knife 26 cutter head and vertebra
Body bone face contact, particular state refer to Fig. 8~10 together.The effect of elastic component 27 is first is that adapt to protect after intervertenral space struts simultaneously
The abutting state for holding processing knife 26 and vertebral bone face, second is that can handle irregular intervertenral space.
Referring to shown in 3 and Figure 10, control unit 4 includes mobile control block 28, hand sprocket wheel 29, the two sides of mobile control block 28
Horizontal extension has handle connector 30 and sprocket wheel connector 31 respectively, and plug-in type can at handle connector 30 and 1 control terminal of handle
It is pivotally connected at the axle center of mobile connection, sprocket wheel connector 31 and hand sprocket wheel 29, transmission chain 22 is respectively connected to the first chain
Wheel 23 and hand sprocket wheel 29, and the transmission space equipped with transmission chain 22 (does not show in figure in handle 1 and in mobile control block 28
Out).When processor is in running order, the arc expansion block 2 of horizontal expansion mechanism drives transmission chain 22 to expand, conveyer chain
Item 22 engages axially to handle towards handle 1 along handle 1 together with hand sprocket wheel 29 so that control block 28 will be moved with hand sprocket wheel 29
Extreme direction is mobile, shakes hand sprocket wheel 29 and rotates transmission chain 22, so that multiple processing units and vertebral bone face contact, at completion
Device is managed to operate vertebral bone surface treatment.
Meanwhile the position that the transmission of transmission chain 22 is spatially located at handle 1 and mobile 28 both ends of control block is provided with
Slanting guide frame 32, it is shown in Figure 18, the setting of guide frame 32 can more favorable guidance processing unit 3 with conveyer chain
Item 22 moves in the transmission space inside handle 1 and mobile control block 28.
Specific working principle is as follows:
By being inserted between two section centrums for processor, so that the bone of the distraction plate 6 of setting symmetrical above and below and two section centrums
Face contact.
Medical worker confirms the pull distance of hand-held control unit 9 according to actual operation needs, logical along strip later
The real-time pressure data that the graduated scale of 10 side-walls of hole and the pressure sensor for observing 6 surface of distraction plate are passed back, slowly pulls
Hand-held control unit 9 holds the mobile mandrel 5 of the mobile drive of control unit 9 and moves axially along handle 1, thus logical to designated position
It crosses to drive and struts the mobile and cooperation completion with jacking component of support rod 7 for two section pyramidal supports to specified altitude assignment, hold control
Component 9 processed with 10 side wall of long stripes through hole because being interference fitted, so its position is still able to maintain after decontroling hand-held control unit 9
It is constant, it keeps strutting afterwards highly constant.
Processing area needs of the medical worker according to vertebral bone face, maximum arc of the confirmation processing unit 3 in vertebral bone surface treatment
Degree, therefore, it is determined that the degrees of expansion of horizontal expansion mechanism.Thereafter, medical worker can be manually rotated hand-held revolving part 16, and according to
The scale that handle is in rotates hand-held revolving part 16 to assigned scale, holds the rotation of revolving part 16 by connector 17 and drives movement
Bar 18 moves axially inside handle 1 along handle 1, and mobile bar 18 is connect with arc expansion block 2 by connecting rod 19, and fixation is auxiliary
The end of part 20 and arc expansion block 2, which is pivotally connected, is used as horizontal expansion support end, logical while then mobile bar 18 is mobile
Connecting rod 19 is crossed to open and be expanded to specified radian arc expansion block 2, since hand-held revolving part 16 is threadedly coupled with handle 1,
Therefore after the rotation to designated position of hand-held revolving part 16, unclamping hand-held revolving part 16 can also keep its position constant.
It is also synchronous with the transmission chain 22 of arc expansion 2 outer arcuate face contact of block while arc expansion block 2 is expanded
