Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: the utility model provides an orthopedics is with hand-held type bone tissue grinder, which comprises an outer shell 1, press the briquetting 2, the vertical axis 3, guide rod 4, spring 5, diaphragm 6, smash piece 7, vertical cylinder 8, smash strip 9, twist rod 10, bottom 11, keep off net 12, accomodate lid 13, elastic ball 14 and ball groove 15, the top end opening part of shell 1 is installed and is pressed briquetting 2, and both constitute sliding connection structure, and press the lower terminal surface of briquetting 2 to install vertical axis 3 and guide rod 4, the bottom of vertical axis 3 is connected with the up end of smashing piece 7, and vertical axis 3 runs through vertical cylinder 8 perpendicularly, and vertical cylinder 8 vertical fixation is in the inside of shell 1, the bottom end opening part threaded connection of shell 1 has bottom 11.

Guide rod 4 is about pressing the central equal angular distribution of piece 2, and perpendicular distribution's guide rod 4 passes through spring 5 sliding connection in the fixed diaphragm 6 of shell 1 inner wall, medical personnel press down when pressing piece 2, vertical axis 3 can drive and smash piece 7 together downstream, until its bottom fully contacts with the bone tissue, and simultaneously, guide rod 4 also can be on diaphragm 6 downstream, spring 5 atress is compressed, when the user loosens the finger, spring 5's resilience effort passes through guide rod 4 and upwards removes, press piece 2 just can kick-back automatically.

Smash the bottom of piece 7 and be bellied arc structure downwards, and this skin weld has the crushing strip 9 of angular distribution such as, the inside and the fluted twist pole 10 threaded connection of vertical cylinder 8, and the both ends of fluted twist pole 10 and the middle disconnection department fixed connection of vertical axis 3, and the bottom and the top of vertical axis 3 respectively with smash piece 7 and press piece 2 fixed connection and rotate and be connected, when the contact is pressed perpendicularly to the bone tissue that smashes the crushing strip 9 in 7 bottoms and keep off net 12 top, smash strip 9 and smash piece 7 and can carry out the high efficiency through horizontal pivoted mode to bone tissue and chew.

The internally mounted of bottom 11 has the fender net 12 of arc structure, and this arc structure coincide with smashing piece 7 from top to bottom, and the bottom of bottom 11 is installed and is accomodate lid 13, accomodate lid 13 and be transparent material, the elastic ball 14 that its top set up coincide in ball groove 15, and ball groove 15 is seted up on the bottom lateral wall of bottom 11, bone tissue granule diminishes, just can pass and keep off net 12 and fall in accomodating lid 13, medical personnel only need to accomodate lid 13 and take off alone and collect bone tissue can.

The working principle is as follows: firstly, medical staff can unscrew the bottom cover 11 from the bottom end of the shell 1, bone tissues needing to be bitten are placed above the blocking net 12 in fig. 5, the bottom cover 11 is installed at the bottom end of the shell 1 again on the premise that the containing cover 13 is stably connected, then the arc-shaped concave areas on two sides of the shell 1 can be held by hands, and the biting operation can be started by applying force to the pressing block 2 through fingers, when the medical staff presses the pressing block 2 downwards, the vertical shaft 3 can drive the crushing block 7 to move downwards together until the bottom end of the crushing block is fully contacted with the bone tissues, meanwhile, the guide rod 4 can also slide downwards on the transverse plate 6, the spring 5 is compressed under force, when the fingers of the user are released, the rebounding acting force of the spring 5 moves upwards through the guide rod 4, and the pressing block 2 can rebound automatically;

when vertical axis 3 follows crushing piece 7 and together moves perpendicularly downwards, vertical axis 3 middle section welded twist rod 10 can be synchronous reciprocates in vertical cylinder 8, because vertical cylinder 8 is the immovable state, under the screw drive effect of twist rod 10 and vertical cylinder 8 inner wall, so twist rod 10 self can be in the rotation state, vertical axis 3 also can be synchronous presses the terminal surface to rotate under briquetting 2, and drive crushing piece 7 and rotate together, consequently when the contact is pressed perpendicularly to the crushing strip 9 in crushing piece 7 bottom and the bone tissue that keeps off net 12 top, crushing strip 9 can carry out high-efficient bite to bone tissue through horizontal rotation's mode with crushing piece 7, bone tissue granule diminishes this moment, just can pass and keep off net 12 and fall in accomodating lid 13, medical personnel only need to accomodate lid 13 and take off alone and collect bone tissue can.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
