[0020] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 , the utility model provides a technical solution:

[0022] A pathological tissue slicer capable of both automatic and manual slicing comprises a base 101, on which a slicing table 201 for placing tissue to be sliced ​​is arranged, and the slicing table 201 can move up and down in a vertical direction; the base 101 is hinged with an adjustment mechanism; a slicing mechanism is arranged on the adjustment mechanism, and the adjustment mechanism is used to control the slicing mechanism to perform slicing action.

[0023] In some implementations of this embodiment, the adjustment mechanism includes two parallel sliding rods 301 and two parallel electric push rods 302, the two electric push rods 302 are connected by a pin, and the pin is hinged to the base 101; one end of the two sliding rods 301 is respectively connected to the fixed ends of the two electric push rods 302, and the central axis of any sliding rod 301 is parallel to the pushing direction of any electric push rod 302; the slicing mechanism is slidably connected to the two sliding rods 301. The electric push rod 302 can be controlled by the corresponding circuit board to control its telescopic action, which is a prior art and will not be described in detail here.

[0024] Specifically, the slicing mechanism includes an outer frame 401, a knife group 402, two sliding sleeves 403 and two springs 404. The knife group 402 is installed in the outer frame 401. When slicing, the knife group 402 is located above the slicing table 201, and the moving direction of the knife group 402 is parallel to the extension direction of the slicing table 201. The two sliding sleeves 403 are symmetrically arranged on both sides of the outer frame 401, and the two sliding sleeves 403 are respectively slidably connected to the two sliding rods 301; the two springs 404 are respectively sleeved on the two sliding rods 301, and one end of any spring 404 is connected to one end of the sliding rod 301 close to the electric push rod 302, and the other end is connected to the sliding sleeve 403. The knife group 402 is a whole, and a blade is installed obliquely inside it.

[0025] In some implementations of this embodiment, two push rods 501 are arranged on the side of the outer frame 401 close to the electric push rod 302, and the two push rods 501 correspond to the two electric push rods 302. The two push rods 501 are used to bear the push pressure of the output ends of the two electric push rods 302 respectively.

[0026] In some implementations of this embodiment, a slot 601 is provided on the outer frame 401, and the blade set 402 can be inserted into the slot 601. The slot 601 is convenient for installing the blade set 402, and convenient for removing the blade set 402 when the blade set 402 needs to be replaced.

[0027] In some implementations of this embodiment, a vertical position adjustment mechanism is provided on the base 101, and the vertical position adjustment mechanism includes a guide rod 701 and a screw rod 702 both of which are provided through the base 101, one end of the guide rod 701 is connected to the slicing table 201; the screw rod 702 is threadedly connected to the base 101, and one end of the screw rod 702 is rotatably connected to the slicing table 201. The screw rod 702 can use a fine adjustment knob to increase its adjustment accuracy.

[0028] In addition, in order to facilitate the control of the adjustment mechanism, the ends of the two slide bars 301 away from the electric push rod 302 are connected by a gripping cross bar 801. When the adjustment mechanism needs to be lifted, the gripping cross bar 801 is convenient for hand force.

[0029] Working principle:

[0030] When slicing manually, first place the slice to be sliced ​​on the slicing table 201, and then adjust the distance between the slicing table 201 and the lower surface of the knife group 402 by rotating the screw 702. After the distance is adjusted, the outer frame 401 is manually controlled to move on the slide bar 301, and the knife group 402 performs the slicing work. After the slicing work is completed, the outer frame 401 returns to the equilibrium position under the action of the two springs 404 to prevent the outer frame 401 from sliding randomly on the slide bar 301 when not in use.

[0031] When slicing automatically, the slice to be sliced ​​is placed on the slicing table 201, and then the distance between the slicing table 201 and the lower surface of the knife group 402 is adjusted by rotating the screw 702. After the distance is adjusted, the two electric push rods 302 are controlled to automatically extend. Figure 2 From the perspective of FIG. 5 , when the output end of the electric push rod 302 abuts against the top rod 501, it continues to extend, and the outer frame 401 moves to the left to perform the slicing work. After the slicing work is completed, the electric push rod 302 shortens, and the outer frame 401 moves to the right under the pull of the two springs 404 until it is in a balanced state.

[0032] When it is necessary to replace the blade group 402, Figure 2From the perspective of the embodiment, the hand holds the holding cross bar 801 to rotate the adjustment mechanism clockwise around the hinge point between the adjustment mechanism and the base 101, thereby increasing the space between the outer frame 401 and the slicing table 201 and facilitating the removal of the knife assembly 402.
