Abstract
The utility model discloses a biological tissue slicer which comprises a pedestal, a stepping motor arranged on the pedestal, a controller for controlling the stepping motor, a fixture assembly and a cutter blade. The fixture assembly comprises a clamper for fixing the sample, a hand wheel, a slipper and a slipper seat, wherein, the hand wheel is connected with the slipper, the clamper is fixed on the slipper seat. The fixture assembly further comprises an L-shaped guide rail seat on which the slipper seat is arranged. The guide rail seat is detachably connected with the clamper in the vertical direction via a ball linear guide rail II. The bottom of the guide rail seat is linked with the stepping motor via a ball screw rod, and is also detachably connected with the pedestal via a ball linear guide rail I. The biological tissue slicer has high accuracy of linear movement and ensures the slicing process stable. The improved feed mechanism has high accuracy of feeding process. The tissue slices have uniformity in thickness. The critical component of the slicer has high anti-wear property. The cutter has low noise during the operation.
Description
Technical field
The utility model relates to a kind of biological tissue section machine.
Background technology
The biological tissue section machine is since the 60 to 70's of last century, increase along with human life's disease WHO kind, and the technical progress of pathology subject, the researchist need carry out deep research and analysis to the diseased tissue cell characteristics, must cut into slices to biological tissue, carry out microscopic analysis then, made the biological tissue section machine of biological tissue section special use.The biological tissue section machine is divided into the ordinary student fabric texture microtome of producing more than the 1um usually according to the slice thickness that cuts out, and produces 0.25-1um half ultra-thin biological tissue section machine, and produces the following ultra-thin biological tissue section machine of 0.25 um.The operating accuracy of ultra-thin biological tissue section machine requires the highest, adopt high precision to grind the carry screw mandrel as the critical component screw mandrel, but this class carry screw axis direction gap is big, the rate of wear is fast, make that the amount of each feeding of microtome can not be identical, cause slice thickness inconsistent.The feeding of microtome need keep rectilinear motion, so in the microtome installation position-limit mechanism must be arranged, and the position-limit mechanism of microtome adopts chute or roller structure in the prior art, and the chute friction is big, and the noise height needs to cooperate powerful motor to finish feeding; And the roller directional properties is poor, and it is indefinite that the space of each roller and wheel between centers makes whole feeding process rock, finally cause cutting the cutting zone that sample departs from blade, and the exercise performance instability, therefore the sample quality of producing is subjected to very big influence.Microtome also has elevating mechanism, is to promote the parts that the sample cutting is used at last, and elevating mechanism directly provides power by handwheel, and moves back and forth the process of finishing lifting by slide block in take-up housing.Because the lifting of sample is direct and the take-up housing interlock, guarantee that without any position-limit mechanism lifting process is on the vertical plane, deviation that occur also makes the sample quality of producing be subjected to very big influence so lifting process is steady.
The utility model content
The technical problems to be solved in the utility model provides a kind of biological tissue section machine, and the operating accuracy height operates steadily, and is wear-resistant, low noise.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the biological tissue section machine comprises base, and be arranged on stepper motor on the base, the controller of control step motor, clamp assembly and blade, the chuck of described clamp assembly fixed sample, handwheel, slide block and take-up housing are formed, described handwheel is connected with slide block, described chuck is fixed on the take-up housing, described clamp assembly also comprises a L-shaped track base, and described take-up housing is installed on the track base, flexibly connects by ball line slideway II and chuck on the described track base vertical direction, described track base bottom is by ball screw and stepper motor interlock, and described track base bottom flexibly connects by ball line slideway I and base.
As a kind of improvement of the present utility model, described track base is provided with a rectangle opening on vertical plane, and described chuck passes perforate over against blade.
As another kind of improvement the of the present utility model, described ball line slideway I becomes to be horizontally disposed with.
The utility model adopts technique scheme, and the linear movement of biological tissue section machine makes that precisely cutting process operates steadily; Improved feed mechanism has high-precision feeding process, the product thickness unanimity of cutting; Critical component is wear-resistant, and noise is low during the cutting machine operation.
Description of drawings
Below in conjunction with the drawings and specific embodiments to further detailed explanation of the utility model.
Fig. 1 is the stereographic map I of a kind of biological tissue section machine of the utility model;
Fig. 2 is the stereographic map II of a kind of biological tissue section machine of the utility model.
Embodiment
As shown in Figure 1, 2, biological tissue section machine of the present utility model comprises base 1, the controller 13 of stepper motor 2 and control step motor 2, the clamp assembly of being made up of chuck 4, take-up housing 5, slide block 12, handwheel 6 and L-shaped track base 7, blade 3, blade holder 14.Blade 3 is arranged on the blade holder 14.
Stepper motor 2, controller 13, clamp assembly, blade 3, blade holder 14 all is arranged on the base 1.Be movably connected by horizontally disposed ball line slideway I10 between track base 7 and the base 1.Track base 7 bottoms are by ball screw 9 and stepper motor 2 interlocks, and track base 7 just can move forward and backward when stepper motor 2 rotates.Because it is level and smooth that the ball line slideway has operation, the orientation accuracy height, anti abrasive advantage is horizontally disposed with further assurance track base 7 simultaneously and can move upward at right and left; Ball screw direction of principal axis gap is little, has high-intensity wear-resisting advantage, has level and smooth exercise performance again, so the feeding process that the utility model biological tissue section machine produces has very high control accuracy and operational process stably.
Clamp assembly is by the chuck 4 of fixed sample, handwheel 6, and take-up housing 5 and slide block 12 are formed.Handwheel 6 is arranged on the base 1, and take-up housing 5 and chuck 4 are arranged on the track base 7, and take-up housing 5 and slide block 12 flexibly connect, and handwheel 6 is connected with slide block 12, and chuck 4 is fixed on the take-up housing 5, can vertical lifting chuck 4 when shaking handwheel 6 work.On vertical plane, have a rectangle opening 11 at track base 7, pass perforate 11 after chuck 4 installs and, pass through ball line slideway II8 and track base 7 flexible connections in the both sides of chuck 4 over against blade 3.By using ball line slideway II8, guarantee that the lifting of chuck 4 is in on the vertical plane for the vertical motion of chuck 4 provides directed guarantee.During cutting, the thing sample that is clipped on the chuck 4 obtains feeding earlier under the promotion of stepper motor 2, realizes cutting by shaking handwheel 6 again.The utility model makes the product thickness unanimity that cuts out by optimizing feeding and lifting process.
