A halfbody is fixed together by the connector of screw one kind, screw hole location and two halfbody connections when cleaning rongeur
Easily there is the dead angle for being difficult to clean up in place, be unfavorable for completely cleaning up rongeur.
The content of the invention
The technical problems to be solved by the invention are：In view of the deficienciess of the prior art, provide a kind of laminectomy rongeur：
Include caliper component, claw beam, Handleset.
The claw beam component includes the vice body of obtuse angle shape, and the upper and lower side of the vice body front portion side forms two
A symmetrical positioning plate；Formed with sliding groove between the vice body and two positioning plates, the two side walls of the sliding groove are pair
The interior concaved circular cambered surface claimed, and the notch position of sliding groove is in the necking shape of outer narrow inner width；On the downside of the sliding groove front end into
Type has width gradually small sliding panel；The slip front edge of board, which is formed, vertical with the sliding panel stings hone lamella；The pincers
The position of the remotely located plate of body forms first handle；The vice body forms rotational support column in angle position；Described
The first magnet of fixed handle component is formed in rotational support column；The sliding groove slidably connects claw beam；The pincers
Pole length is more than the length of positioning plate；Hone lamella is stung in the front end of the claw beam for activity, and the claw beam rear end forms slide head.
The handle body and second handle of Handleset integrally connected successively；The handle body is corresponding with slide head
Position form limiting slot；The handle body top forms to suck the 4th magnet of the slide head；Described
Handle body position corresponding with rotational support column forms the U-shaped rotation slot coordinated with rotational support column；The handle body exists
The bead formed on back of rotation slot has the 3rd magnet；First handle position corresponding with the 3rd magnet forms and the 3rd magnet
The second magnet to repel each other；Stainless steel one-pass molding is respectively adopted in the caliper component, claw beam, Handleset.
Compared with prior art, the beneficial effects of the invention are as follows：
When specifically used, sliding panel is placed in and will sting under the vertebral plate of bone by operator, and first, second hand is mediated with hand-power
Handle, claw beam move forward under the promotion of sliding groove, and the vertebral plate for being now placed in stinging among hone lamella and claw beam is stung under pressure
Disconnected, bone operation is once stung in completion；Unclamp hand pressure of holding with a firm grip after, since the second magnet and the 5th magnet repel each other, first handle and
Second handle can automatically spring open, and claw beam is also due to slide head and the 4th magnet are attracting, the caliper component, claw beam and handle group
Part is detachable；By this design, make the convenient installation of the present invention and cleaning and sterilizing；Caliper component, claw beam and the hand
Stainless steel one-pass molding is respectively adopted in handle component.

Embodiment
The embodiment of the present invention is made a detailed explanation below according to attached drawing.
According to Fig. 1 to Fig. 6, the present embodiment is a kind of laminectomy rongeur：Include caliper component 1, claw beam 2, handle
Component 3.
The claw beam component includes the vice body 11 of obtuse angle shape, and the upper and lower side of the vice body front portion side forms
Two symmetrical positioning plates 12；Formed with sliding groove 121, two sides of the sliding groove between the vice body and two positioning plates
Wall is symmetrical interior concaved circular cambered surface, and the notch position of sliding groove is in the necking shape of outer narrow inner width；On the downside of the sliding groove
Front end forms width gradually small sliding panel 13；The slip front edge of board, which is formed, vertical with the sliding panel stings hone lamella
14；The position of the remotely located plate of the vice body forms first handle 15；The vice body forms rotation in angle position
Support column 16；The first magnet 161 of fixed handle component is formed in the rotational support column.
The sliding groove slidably connects claw beam 2；The claw beam length is more than the length of positioning plate；The claw beam
Hone lamella is stung in front end for activity, and the claw beam rear end forms slide head 21.
The Handleset handle body 31 of integrally connected and second handle 32 successively；The handle body and slide head
Corresponding position forms limiting slot 34；The handle body top forms to suck the 4th magnet of the slide head
