Description
Technical field
This utility model belongs to a kind of corollary apparatus of medical apparatus and instruments.
Background technology
The not leukorrhagia slicing device that existing C T machine has, its slice thickness do not satisfy the instructions for use of 2mm plain film scanning at 3.1-3.3mm.And the CT machine that has has slicing device down, but dumb, and its location is also accurate inadequately, has also reduced the complete machine performance simultaneously.
Summary of the invention
At existing C T machine leukorrhagia slicing device not, its slice thickness does not reach instructions for use and has dumb, the location inaccuracy of CT machine of section down, influence the problem of complete machine performance, this utility model provides a kind of kinematic accuracy height, picture quality is good, slice thickness meets the demands and the CT machine that strengthens the complete machine performance with slicing device down.
This utility model is made up of section motor, line slideway assembly, gear and tooth bar, bracing frame, flashboard, frock assembly and control circuit.Flashboard has mainly adopted the fiber glass epoxy material, and characteristics are to compare easy-formation with metal material, and are in light weight, good rigidly, main frame easy-formation not in high speed rotating, thus guarantee to be consistent with ray plane.The support of flashboard adopts supported at three point to help flashboard accuracy at the volley.Type of belt drive adopts motor driven gear and tooth bar that flashboard is seesawed.On-the-spot installation will adopt frock to guarantee, guarantees the size 88mm of swivel plate to ray plane, and adjusts the gap of wheel and rack gap and line slideway.
The line slideway assembly comprises 1～3 line slideway, 1～3 line slideway is contained in the corresponding installation site of flashboard respectively, bearing is installed on the swivel plate, the line slideway slide block is installed on the bearing respectively, motor is directly installed on the intermediary bracing frame, gear is connected with the output shaft of motor, tooth bar is contained on the slide block above the intermediate support and gears engaged, the fit clearance of rack and pinion is 0.05-0.15mm, guarantee the stationarity and the accuracy of motion, control circuit major control motor and photoswitch, restriction ram movement desired position.
Following section control circuit is made up of three parts: position detecting circuit, decision logic circuit, operating part circuit are formed.Position detecting circuit arranges RP1, RP2 by photoswitch U1-U4 and resistance and integrated circuit U5 74HC541 forms.RP1 provides photoswitch emission diode electric current, and RP2 is as the receiving terminal pull-up resistor, and detected signal is delivered to U5 and carried out shaping and handle and deliver to the decision logic circuit.
The decision logic circuit is made up of integrated circuit U6MACH4A256/128.To going here and there from the next instruction of JP1 and changing, separate out position command: compare position command and current position, just make and change, reverse or the judgement that puts in place, and output reverse signal LREV1, positive rotaring signal LFWD1 and put signal LRDY1 in place to the operating part circuit.The output signal interlocking in the decision logic circuit of just changeing, reverse can not be simultaneously effectively.
The operating part circuit is made up of driver U21 ULN2803, triode Q4, Q5, Q10, motor M 1 and peripheral components.The reverse signal LREV1 of decision logic circuit output, positive rotaring signal LFWD1 and put signal LRDY1 in place after driver U21 is anti-phase drives audion Q5, Q10, light emitting diode D12; Carry out the information that counter-rotating, positive rotating function and slice position put in place respectively.
Work process is as follows:
The decision logic circuit by integrated circuit U6 receive new slice position order is set after, to desired location and current position relatively, just make and change, reverse or the judgement that puts in place.Judging has three kinds of possibilities: be provided with than physical location or big or little or equal.
Be provided with when bigger than physical location, positive rotaring signal LFWD1 effectively be a high level, after driver U21 is anti-phase, drives audion Q10, the Q10 conducting, and+15V voltage is added in direct current generator M1 anode, and motor just changes, and the big direction in slicing device tangential section position is moved.At this moment, position detecting circuit detects the position of section constantly and feeds back to the decision logic circuit.In case put in place, positive rotaring signal LFWD1 lost efficacy, not conducting of audion Q10, and motor M 1 does not stop operating because of there being power supply.The decision logic circuit is exported the signal LRDY1 that puts in place simultaneously, after driver U21 is anti-phase, drives diode D12, and the bright indication section of D12 adjusted puts in place.
Be provided with than physical location hour, reverse signal LREV1 effectively is a high level, after driver U21 is anti-phase, drives audion Q5, after the Q5 conducting, makes audion Q4 conducting, the Q4 conducting, and-15V voltage is added in direct current generator M1 anode, the motor counter-rotating.The direction motion that slicing device tangential section position is little.At this moment, position detecting circuit detects the position of section constantly and feeds back to the decision logic circuit.In case put in place, reverse signal LREV1 lost efficacy, audion Q5, not conducting of Q4, and motor M 1 does not stop operating because of there being power supply.The decision logic circuit is exported the signal LRDY1 that puts in place simultaneously, after driver U21 is anti-phase, drives diode D12, and the bright indication section of D12 adjusted puts in place.
Be provided with when equal with physical location, just change, reverse signal all lost efficacy, motor is motionless.The signal LRDY1 that puts in place output drives diode D12 after driver U21 is anti-phase, the bright indication section of D12 adjusted puts in place.
This utility model kinematic accuracy height is used on the CT machine, makes CT machine picture quality good, and slice thickness improves the complete machine performance between 2.4-2.6mm.
