Specific embodiment
Now in conjunction with drawings and examples, the invention patent is described in detail, but the implementation of the invention patent is not limited only to
This.
A kind of cartilage grinding device according to shown in Fig. 1-6, by pressing plate (1), feature board (2), collecting bin (3), netted
Blade (4) and limit plate (5) composition, the pressing plate (1) is by operation portion (11), guide part (12) and prevents being adhered raised (13)
It constitutes, operation portion (11) is located at top, can be convenient patient and carries out loading or unloading operation；Guide part (12) below operation portion (11)
It can guarantee that push action is smooth in pressing, and guarantee that the anti-protrusion (13) that is adhered can be smoothly inserted into netted blade (4) hole；
The anti-protrusion (13) that is adhered is evenly distributed on guide part (12) lower end surface, is matched with the mesh of netted blade (4).It is described
Feature board (2) be made of the preset chamber of cartilage (21), limited post (22), limited step (23) and limiting tooth slot (24), it is described
Limiting tooth slot (24) be structure wide at the top and narrow at the bottom, facilitate netted blade (4) install while, can cooperate with limit plate (5)
It prevents from falling off in netted blade (4) use process；The limited step (23) is located above limiting tooth slot (24), limit
The preset chamber of tooth slot (24) enclosed space, that is, cartilage (21), for placing precomminution cartilage when crushing cartilage；Under feature board (2)
Holding the distribution of quadrangle central symmetry, there are four limited post (22).The top quadrangle of the collecting bin (3) is provided with to be limited with feature board (2)
Position column (22) matched limited post detent (32) can cooperate with it and guarantee collecting bin (3) and feature board (2) in crushing process
Relatively fixed, after can effectively collecting chopping cartilage particles；After collecting chamber (31) on collecting bin (3) is used to collect chopping
Cartilage, opening size are greater than the preset chamber of cartilage (21) size, it is ensured that the cartilage particles after all choppings can fall into receipts
Collect in chamber (31).The netted blade (4) is made of criss-cross blade.Blade aperture after a combination thereof is standard square
Shape, side length can customize according to actual needs, to guarantee that the cartilage particles after chopping are uniform.Netted blade (4) surrounding after combination
Limiting tooth slot (24) bottom of feature board (2) can be inserted to reach fixed blade effect in extended segment.The limit plate (5)
It is made of the limiting tooth (52) of evenly distributed arrangement on limit plate pedestal (51) and pedestal.51 moulding of limit plate pedestal and feature board
(2) limited step (23) matching, matched limiting tooth slot (24) can be inserted in limiting tooth (52), until limit plate
Pedestal (51) is entirely enclosed in limited step (23), and bottom surface is flushed with feature board (2) upper surface, guarantees that netted blade (4) are inserted into
Position is fixed after feature board, guarantees cartilage crushing effect.
One concrete application of the present embodiment are as follows:
A kind of cartilage grinding device, before use, the processing that carry out disinfection, and by (2) four limited posts (22) of feature board
It is inserted into the limited post detent (32) of collecting bin (3), limited post (22) and limited post detent (32) they are centrosymmetric structure, therefore
Without considering direction, it is optionally plugged into, while removing pressing plate and being placed on one side for use.In use, pretreated cartilage is put
Enter the preset chamber of cartilage (21) of feature board (2), cartilage, will since the presence meeting indwelling of netted blade (4) is in preset chamber (21)
Preset chamber (21) is inserted into pressing plate (1) guide part (12) one end, and pushing of taking advantage of a situation, cartilage can be under the compressings of pressing plate (1)
Roughly the same particle is cut by netted blade (4) to fall into collecting bin.The anti-protrusion (13) that is adhered in pressing plate (1) is being pressed
It can be inserted under the movement of pressure in the mesh of corresponding netted blade (4), since the height of raised (13) is slightly above netted blade (4)
Highly, therefore it can guarantee that all cartilage particles are both fallen in collecting bin (3).It is noted that the guide part (12) of pressing plate (1)
It is centrosymmetric structure with the anti-protrusion (13) that is adhered, therefore when preset chamber (21) of insertions function plate (2), same to limited post (22) class
Seemingly, it without considering direction, is optionally plugged into.After the completion of cartilage processing, collecting bin (3) is removed from feature board (2), is taken out
Cartilage particles in collecting chamber (31) are for performing the operation.
The advantages of basic principles and main features and the invention patent of the invention patent have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the invention patent is not restricted to the described embodiments
