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 technique
Currently, Orthopedic Clinical is screwed into screw, when especially operating space is narrow, spiral shell mostly is held instead of hand using holding pincers
Nail comprising left handle and right handles, the connecting rod of left handle and the connecting rod of right handles are hinged, two connecting rod rear portions difference
It is connected with tooth form fixing card, the front end of two connecting rods is respectively provided with jaw, and each jaw inwardly curves semicircle, two jaw closures
Become a circle afterwards；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 a circle, and with pincers is held, to hold stickfast solid, does not fall off, solve hand-held nail be easy to slide and
The unworkable problem of operating space hand of lower hour.Hand-held nail is avoided to stab the danger of hand simultaneously.But it is effective to hold pincers
Holding 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 being 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.
Summary of the invention
The present invention provides a kind of orthopaedic screw guide-localization pincers, realizes screw rotation while realization to 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 that: 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 for clamping front end
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
Two rotatable roller bearings, the shaft of roller bearing are arranged on the side of inner groovy, and the central axis 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 clamped to orthopaedic screw, 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 with it.
The groove is criss-cross 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 and bottom surface of roller bearing slot.
It is rotation setting between the roller bearing and shaft, upper top surface and the bottom surface of roller bearing slot are fixed in the both ends of shaft
On, filled solid lubricating grease in gap is rotated between roller bearing and shaft as the mutual rotation of the two, and lubrication is provided.
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, both ends of the shaft rotates in rotation slot.
It solves the problems, such as that tradition holds pincers and holds nail and be screwed into screw and cannot be considered in terms of, 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 guiding that original needs can only be more loose and is downwardly applied to pressure without being capable of clamping, position
It moves without horizontal displacement, pressure can be applied to screw by holding pincers, be screwed into conducive to screw.

Specific embodiment
The utility model is a kind of clamp screws use when installing fixing screws for orthopaedics, clamps while guaranteeing screw
Rotation can be turned.
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 first caliper 1 and the second caliper 2
Front and rear end is in the angle of 120-150 degree, and the first caliper 1 and the second caliper 2 are hinged and connected in the rear end of angular position, and first
The medial surface of caliper 1 and the second caliper 2 in clamping front end sets the inner groovy 3 of arc respectively, and the inner groovy 3 of two calipers is opposite to be formed
Round shape, the side of the inner groovy 3 of each caliper are set there are two rotatable roller bearing 4, and inner groovy 3 is arranged in the shaft 6 of roller bearing 4
On side, roller bearing 4 is spaced 90 degree of settings in the circle that inner groovy forms, i.e., on the circle of inner groovy composition in caliper front end
Side is as initial position with 45 °, 135 °, 225 °, 315 ° of setting roller bearings.
The central axis 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 clamps,
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 with it.
