Definitions
- the invention relates to a knife holder for microtome blades with the features of the preamble of claim 1.
- Microtomes are used to produce thin sections of various preparations from medicine, biology and botany, materials research and quality control of technical substances.
- the production of these thin sections is done with knives of different shape and texture.
- steel knives made of selected tool steels, which are produced in various types of grinding.
- regrindable solid knives find kiingenförmige cutting knives, so-called disposable blades, a widespread use. Disposable blades are usually replaced by new ones after their service life has been exceeded.
- glass knives and diamond knives are for special use in use.
- knife carriers and knife holders are known in microtome technology, which additionally differ in their design for which microtome type they are intended for.
- the knife holders used fulfill the main purpose of stably clamping the respective microtome blade in order to achieve the desired cutting result.
- a knife holder with a pressure plate for clamping a blade-shaped cutting blade is known from DE 44 35 072 C1.
- the knife holder includes a base body and a jaw with a contact edge on which the back of the cutting blade rests. With the pressure plate, the cutting blade is pressed against the jaws.
- the length of the contact edge may be greater than the length of the cutting blade.
- a knife holder for a nachschleifbares massive wedge-shaped steel knife is shown and described in DE 195 06 837 C1.
- the steel knife generally has sufficient stability, so that it is usually clamped only in its end regions.
- a device may, for example, consist of a circle segment arc pivotally mounted on a base, on which the base body of the knife holder is fastened.
- a device may, for example, consist of a circle segment arc pivotally mounted on a base, on which the base body of the knife holder is fastened.
- knife holders may have a so-called finger protection.
- a finger guard can from a on the body of the Knife holder pivotally hinged rectangular bracket exist, the bridge connecting the two U-leg bridge extends in an end position on the blade edge and thereby prevents accidental picking up on the blade cutting edge.
- a finger guard can be seen for example from DE 198 24 024 A1.
- the ejection device is equipped for this purpose with an ejection element acting on the blade cutting edge.
- a spring element holds the ejection element in the rest position outside the side edge.
- the design of the ejector as a lever mechanism with a flat eject lever whose thickness is adapted to the blade thickness.
- the flat ejection lever can be brought into operative connection on one of the side edges of the blade.
- the ejection device includes a plunger, the plunger head is directed to a free-standing side edge of the blade cutting edge.
- the free-standing side edge is understood to be the region of the microtome blade which, in the clamped state, protrudes freely from the knife holder adjacent to the blade cutting edge.
- a generally bolt-shaped plunger is placed in a tangential to the contact edge of the microtome blade movement, the plunger head brought into operative connection with the freestanding side edge and so the microtome blade side ejected. Because of the orientation of the plunger head to the freestanding side edge of the plunger head can be dimensioned larger area. This facilitates the adjustment of the ejection device.
- an actuating element of the ram mechanism under spring tension, rigidly connected to the plunger push button.
- the spring tension can be generated by different spring elements.
- a coiled around the plunger helical spring offers particular advantages in terms of compactness and maximum displacement of the plunger movement.
- the ejection device can of course be firmly connected to the base body at each area of the knife holder, as long as the microtome blade can be brought into a position by its actuation, in which it can be gripped securely by the operating personnel.
- a rectangular bracket which can be pivoted over the pressure plate is mounted on the base body so that its bridge rests on the pressure plate in an end position above the blade edge and the ejection device is arranged on the bracket in the region of the bridge.
- the bracket may be designed so that its bridge in the production of cuts the blade cutting edge so that a picking on this is effectively prevented and thus acts as a finger guard.
- Fig. 4 is a rear view of the knife holder, with ejection device in
- FIG. 6 shows the rear view of the knife holder as in FIG. 3
- FIG. 7 shows a detail of the lateral view of the knife holder
- FIG. 8 shows a section through the ejection device.
- FIG. 1 shows a view of a knife holder 1 according to the invention, in which a microtome blade 2 bears against a contact edge 4 and is clamped between the base body 3 and the pressure plate 5 by means of a clamping knob 16.
- the length of the microtome blade 2 is chosen so short that it is clamped over its entire length and thus fully usable. Only the blade edge 6 projects out of the knife holder 1.
- the base body 3 is laterally displaceable on a segmental bow 17 parallel to the blade cutting edge 6.
- the segmental bow 17 is pivotable in a known manner on a base 18 along its cylindrical back surface stored, so that the so-called clearance angle, that is, the orientation of the microtome blade 2 is adjustable relative to the not shown sample to be cut.
- a pivotable about a pivot axis 19 rectangular bracket 14 is hinged, which is in a réellegeklapp ⁇ th position.
- the ejection device 8 consists of a guide 20 in which the push button 13 rigidly connected to the plunger 12 is movably mounted. The axis of the plunger 12 extends parallel to the contact edge. 4
- FIG. 2 shows the knife holder 1 with an upwardly folded bracket 14.
- the bridge 15 extends over the microtome blade 2, which can not be seen in this illustration, thus preventing unintentional picking up on the otherwise free-standing blade cutting edge 6 spring-loaded push button 13, the plunger 12 are moved in the direction of the microtome blade 2, the plunger head 10 is brought into operative connection with the microtome blade 2 and ejected by further impressions.
- the microtome blade 2 is shown in an ejected position. It protrudes laterally so far beyond the base body 3, that it can be easily detected for complete removal by the operator.
- the bracket 14 is again in the same position as shown in Figure 1.
- FIG. 4 The rear view of the knife holder 1 shown in Figure 4 shows the upwardly folded bracket 14 with attached ejector 8 as in Figure 2 in the rest position.
- the push button 13 and the plunger 12 form an axis which passes through the guide 20.
- Figure 5 shows the knife holder 1 in a further rear view, wherein the push button 13 is fully pressed into the ejector 8 and therefore the plunger 12 projects far out of the guide.
- the microtome blade 2 is in an ejected position.
- FIG. 6 shows the knife holder 1 with ejected microtome blade 2.
- the pivotable bracket 14 is in a folded-down position and thus releases the laterally ejected microtome blade 2 for gripping by the operator.
- FIG. 7 shows a side enlarged detail of the knife holder 1 with a vertical view of the plunger head 10.
- the end face of the plunger head 10 is assigned to the freestanding side edge 11 of the microtome blade 2.
- the guide 20 fastened to the bracket 14 in the region of the bridge 15 can be clearly seen.
- the ejector 8 is shown in section.
- the push button 13 is rigidly connected via a screw 21 to the plunger 12.
- a spring element 9 generates a bias voltage which holds the plunger head in the rest position in contact with the guide 8.
