Description
Technical field
The present invention relates to a kind of orthopaedic screw guide-localization pincers, belong to a kind of tool that medical field uses.
Background technology
Currently, Orthopedic Clinical is screwed into screw, when especially operating space is narrow, screw mostly is held instead of hand using holding pincers,
It includes left handle and right handles, and the connecting rod of left handle and the connecting rod of right handles are hinged, and two connecting rod rear portions connect respectively
It is connected to tooth form fixing card, the front end of two connecting rods is respectively provided with jaw, and each jaw inwardly curves semicircle, after two jaws are closed
As a circle；The jaw of left handle connecting rod front end and the jaw of right handles connecting rod front end merge exactly one
Nail, can be fixed in jaw by circle, and with pincers is held, to hold stickfast solid, does not fall off, and solve hand-held nail and be easy to slide and behaviour
Make the unworkable problem of space hand of lower hour.Hand-held nail is avoided to stab the danger of hand simultaneously.But it holds pincers effectively to hold
Nail needs jaw and screw to be in close contact, when both having held screw can not rotary screw, this makes troubles to be screwed into screw, especially
When hip replacement when acetabular bone drivescrew, narrow space when using soft bar universal screwdriver, can not treat being screwed into screw and apply
Pressure, and unresolved screw is screwed into difficult problem.
Invention content
The present invention provides a kind of orthopaedic screw guide-localization pincers, realizes to realizing screw rotation while screw clamping, guiding
Turn to be screwed into, solves the problems, such as that original pliers can not rotate screw in clamp screws and turn.
To achieve the above object, the technical solution adopted by the present invention is：A kind of orthopaedic screw guide-localization pincers, feature
It is, including the first caliper and the second caliper that the front and rear end of the first caliper and the second caliper is in the angle of 120-150 degree, the
One caliper and the second caliper are hinged and connected in the rear end of angular position, and the first caliper and the second caliper are in the medial surface that front end is clamped
The inner groovy of arc is set respectively, and the inner groovy of two calipers is opposite to form round shape, and the side of the inner groovy of each caliper is equipped at least
The shaft of two rotatable roller bearings, roller bearing is arranged on the side of inner groovy, and the central shaft of roller bearing and the front end of caliper open and close
Vertical between the face that swing sweeping is crossed, the surface of roller bearing is equipped with groove, and roller bearing contacts after the first caliper and the engagement of the second caliper front end
The outer surface of orthopaedic screw simultaneously applies the power that orthopaedic screw is clamped, the circle that roller bearing is formed in inner groovy at least four directions
Spaced at equal angles around, orthopaedic screw rotation roller bearing rotate therewith.
The groove is crisscross concave convex texture or the round shape lines along circumferential surface.
The side of the inner groovy of each caliper is provided with roller bearing slot, and the roller bearing is arranged in roller bearing slot, the roller bearing
Shaft be arranged on the upper top surface of roller bearing slot and bottom surface.
It is fixed on the upper top surface and bottom surface of roller bearing slot, rolls for rotation setting, the both ends of shaft between the roller bearing and shaft
Gap filled solid lubricating grease is rotated between axis and shaft provides lubrication for the mutual rotation of the two.
The end that integral structure between the roller bearing and shaft, the upper top surface of roller bearing slot and bottom surface are equipped with shaft is embedded in
Rotation slot, shaft both ends rotate in rotation slot.
It solves the problems, such as that tradition holds pincers and holds nail and be screwed into screw and can not take into account, is changed on the basis of tradition holds pincers
Into the design not only plays the role of securely holding screw, and does not influence being screwed into for screw, and can to give screw certain by holding pincers
Pressure is screwed into conducive to screw.
Addition plane roller bearing, the cylindrical roller that can be rolled at pincers jaw are held in tradition to contact with screw, both play handle
It holds screw, and can be acted on because of the synchronous rotary of roller bearing and do not influence screw and be screwed into, because the design uses roller bearing, and aspheres, make spiral shell
Nail only has relative rotation with jaw, abandons the direction that original needs can only be more loose and is oriented to and cannot be clamped and be downwardly applied to pressure, position
It moves without horizontal displacement, pressure can be applied to screw by holding pincers, be screwed into conducive to screw.

Specific implementation mode
The present invention is a kind of clamp screws use when installing fixing screws for orthopaedics, is clamped while ensureing that screw can
Turn rotation.
The primary structure of the present apparatus as shown in Figure 1,
7 guide-localization pliers of orthopaedic screw, including the first caliper 1 and the second caliper 2, the front end of the first caliper 1 and the second caliper 2
It is in the angle of 120-150 degree with rear end, the first caliper 1 and the second caliper 2 are hinged and connected in the rear end of angular position, the first caliper
1 and second medial surface of the caliper 2 in clamping front end set the inner groovy 3 of arc respectively, the opposite composition of inner groovy 3 of two calipers is justified
The side of shape, the inner groovy 3 of each caliper is set there are two rotatable roller bearing 4, and the shaft 6 of roller bearing 4 is arranged in the side of inner groovy 3
On face, roller bearing 4 is spaced 90 degree of settings in the circle that inner groovy forms, i.e., with caliper leading inside on the circle of inner groovy composition
Face is as initial position with 45 °, 135 °, 225 °, 315 ° of setting roller bearings.
The central shaft of roller bearing 4 is vertical between swinging the face that sweeping is crossed with the folding of the front end of caliper, and the surface of roller bearing 4 is equipped with groove
5, the first caliper 1 and 2 front end of the second caliper engagement after roller bearing 4 contact orthopaedic screw 7 outer surface and four direction apply pair
The power that orthopaedic screw 7 is clamped,
The round spaced at equal angles around that roller bearing 4 is formed in inner groovy 3, orthopaedic screw 7 rotate roller bearing 4 and rotate therewith.
The groove 5 is crisscross concave convex texture or the round shape lines along circumferential surface.
The side of the inner groovy 3 of each caliper is provided with roller bearing slot 8, and the roller bearing 4 is arranged in roller bearing slot 8, described
The shaft 6 of roller bearing 4 is arranged on the upper top surface of roller bearing slot 8 and bottom surface.
There are two types of connection type between roller bearing 4 and shaft 6, one is being rotation setting between roller bearing 4 and shaft 6, the two of shaft 6
End is fixed on the upper top surface and bottom surface of roller bearing slot 8, and it is two that gap filled solid lubricating grease is rotated between roller bearing 4 and shaft 6
The mutual rotation of person provides lubrication.
Another kind is integral structure between roller bearing 4 and shaft 6, and the upper top surface of roller bearing slot 8 and bottom surface are equipped with shaft 6
The rotation slot of end insertion, 6 both ends of shaft rotate in rotation slot.
It is contacted with orthopaedic screw by roller bearing, as shown in fig. 6, while effectively accommodating orthopaedic screw, because of the rotation of roller bearing, spiral shell
Nail can rotate while being accommodated, and be screwed into convenient for screw, and cylindrical roller only has screw displacement, and can not do other fortune
Dynamic, surgeon can be by hand-held pliers to screw pressure testing, while providing rotary power to screw by universal screwdriver, is convenient for
Screw is screwed into steel plate and bone.
