Abstract
The utility model provides a surgery operation is with universal ware that struts, including two sets of poles that strut, strut the pole by the handle of an organic whole with strut the arm and constitute, two intermediate positions that strut the pole are articulated, the middle part of handle sets up the reset spring piece, the tip of handle sets up the locking lever, every tip that struts the arm sets up the rotation dead axle, the periphery cooperation of rotating the dead axle sets up rotates the cover, the tip that rotates the cover sets up the fix with screw hole, rotate the cover inboard and offer interior ring channel, rotate the inboard of dead axle and offer outer ring channel, interior ring channel corresponds with outer ring channel, set up the several ball between interior ring channel and the outer ring channel, the rotation is sheathe in and is seted up the screw, and the cooperation sets up bolt, the tip and the cooperation of rotation dead axle of bolt on the screw. The utility model discloses in, the rotation cover rotation flexibility that struts the arm tip is stronger, adopts the ball cooperation softer, can prevent axial displacement simultaneously, improves the stability and the security of use.
Description
Technical field
This utility model belongs to medical instruments field, specifically a kind of universal dilator of surgical operation.
Background technology
At present conventional clinically dilator mostly is unidirectional and struts mode, its direction strutted and angle are changeless, dilator is once install and having determined that the direction strutted, this is appearing merely joint or fracture end internal structure fashion can meet demand, and in operation, need to change corresponding fracture the relative angle in joint can be beneficial to the nest point and the angle that reset be accomplished by again regulating by operation requirement dilator time fixing, sometimes operation needs repeated multiple times being adjusted, not only waste the operating time of preciousness, be more easily caused and resetted and fixing partial failure.CN204468233U discloses a kind of universal orthopedic distraction reduction device, the universal fixture motility of the end of this device, less stable.
Utility model content
This utility model provides a kind of universal dilator of surgical operation, in order to solve defect of the prior art.
This utility model is achieved by the following technical programs:
A kind of universal dilator of surgical operation, bar is strutted including two groups, strut bar by the handle of one and to strut arm and form, two centre positions strutting bar are hinged, the middle part of handle arranges reseting spring leaf, the end of handle arranges securing rod, each end strutting arm arranges rotation dead axle, the periphery rotating dead axle is equipped with turning set, the end of turning set arranges screw fixed hole, offers interior annular groove inside turning set, and outer annular groove is offered in the inner side rotating dead axle, interior annular groove is corresponding with outer annular groove, arranges several ball between interior annular groove and outer annular groove；Offering screw on turning set, screw is equipped with bolt, the end of bolt coordinates with rotating dead axle.
A kind of universal dilator of surgical operation as above, annular trough is offered in the described periphery rotating dead axle, and the end of bolt coordinates with annular trough.
A kind of universal dilator of surgical operation as above, the end of described bolt arranges slipmat, and slipmat can coordinate with rotating dead axle.
A kind of universal dilator of surgical operation as above, the end of described bolt arranges the handler of buttferfly-type.
The utility model has the advantages that: in this utility model, the turning set strutting arm end rotates motility relatively by force, adopts ball engagement softer, is possible to prevent to move axially simultaneously, improves stability and the safety of use procedure.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Figure number marks: 1 handle, and 2 strut arm, 3 screw fixed holes, 4 turning sets, 5 reseting spring leafs, 6 securing rods, and 7 rotate dead axle, 8 interior annular groove, 9 outer annular groove, 10 balls, 11 bolts, 12 screws, 13 inside grooves, 14 slipmat.
Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in this utility model embodiment, technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
A kind of universal dilator of surgical operation, as shown in the figure, bar is strutted including two groups, strut bar by the handle 1 of one and to strut arm 2 and form, two centre positions strutting bar are hinged, the middle part of handle 1 arranges reseting spring leaf 5, the end of handle 1 arranges securing rod 6, each end strutting arm 2 arranges rotation dead axle 7, the periphery rotating dead axle 7 is equipped with turning set 4, the end of turning set 4 arranges screw fixed hole 3, interior annular groove 8 is offered inside turning set 4, outer annular groove 9 is offered in the inner side rotating dead axle 7, interior annular groove 8 and outer annular groove 9 are corresponding, several ball 10 is set between interior annular groove 8 and outer annular groove 9；Offering screw 12 on turning set 4, screw 12 is equipped with bolt 11, the end of bolt 11 coordinates with rotating dead axle 7.In this utility model, the turning set strutting arm end rotates motility relatively by force, adopts ball engagement softer, is possible to prevent to move axially simultaneously, improves stability and the safety of use procedure.
Specifically, in order to improve turning set 4 and rotate the fitment stability of dead axle 7, annular trough 13 is offered in the periphery rotating dead axle 7 described in the present embodiment, and the end of bolt 11 coordinates with annular trough 13.Bolt 11 is possible to prevent turning set 4 and rotates dead axle 7 axially relative movement.
Concrete, in order to improve turning set 4 and rotate stability when dead axle 7 is relatively fixed, the end of the bolt 11 described in the present embodiment arranges slipmat 14, and slipmat 14 can coordinate with rotating dead axle 7.The coefficient of friction of slipmat 14 is big, and stability is higher.
Further, in order to and conveniently twist bolt 11, the end of the bolt 11 described in the present embodiment arranges the handler of buttferfly-type.
Last it is noted that above example is only in order to illustrate the technical solution of the utility model, it is not intended to limit；Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent replacement；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of this utility model.
