Description
Technical field
Bone surgery appliance technology is the utility model is related to, especially a kind of novel orthopaedics are clamped with screw clamping.
Background technology
At present, piece or fixed plate are fixedly connected with bone surgery to be frequently necessary to use spiral shell when orthopaedics reseting fixture
Nail, due to screw small volume, when being fixed using screw, clamp screws easily come off, and cause operating time to extend, and
When screw is tightened in rotation, the apparatus of clamp screws cannot be rotated with screw, and screw loosening is easy to cause in rotary course
Offset direction, operation is time-consuming and laborious, considerably increases the difficulty of medical worker's surgical procedure.
Utility model content
A kind of novel orthopaedics are provided the purpose of this utility model is to overcome above-mentioned technical disadvantages to be clamped with screw clamping.
The utility model solve the technical solution that uses of technical problem for:A kind of novel orthopaedics are clamped with screw clamping, including
Clamp handle, arc tong arm, folder cylinder, rotation clamping piece, the left and right clamp handle is hinged by hinge shaft, and the rear end of clamp handle, which is equipped with, to be referred to
Ring, the clamp handle end of hinge shaft front end are equipped with arc tong arm, and the end of arc tong arm is equipped with semicircular folder cylinder, rotation is equipped with folder cylinder
Turn clamping piece.The present apparatus uses clamp type structure, and finger ring opening and closing gripper clamp is inserted into by finger, easy to use, equipped with arc
Tong arm, when clamping rotary screw, will not block surgical field of view, surgical procedure will not be caused to interfere, gripper clamp pinching screw
When at left and right sides of semicircular folder cylinder can close to form complete annular, left and right folder cylinder inner cavity can communicate, rotate clamping piece
Pinching screw, rotation can rotate when tightening screw with screw, and screw will not loosen in rotary course, firm grip, spiral shell
Nail will not fall off or offset direction, after screw rotation is screwed into most, can unclamp screw, easy to use, time saving and energy saving, saves
Operating time, reduces the operation difficulty that medical worker tightens screw.
The rotation clamping piece is made of intermediate plate, connecting rod, support shell, ball, and the inner side of the folder cylinder is equipped with sliding groove, connecting rod
It is inserted in sliding groove, presss from both sides the interlinking lever end in cylinder and be equipped with support shell, ball is housed in support shell, the connecting rod other end is equipped with intermediate plate.Rotation
Clamping piece can will ask shell and ball to load in folder cylinder by sliding groove, and during intermediate plate pinching screw, ball is withstood on folder cylinder inner wall,
When screw is tightened in rotation, intermediate plate pinching screw, ball can roll between support shell and folder cylinder inner wall, and connecting rod can be along sliding groove
Rotated with screw, so that rotation clamping piece is integrally rotated with screw, during screw-driving, rotation clamping piece will not pine
Screw is opened, firm grip, will not cause toner screw or screw off normal, easy to use, save operation time.
Beneficial effect is possessed by the utility model:The structure design of the utility model is reasonable, easy to use, operation
Shi Buhui blocks surgical field of view, and surgical procedure will not be caused to interfere, and screw clamping is firm, rotates clamping piece when tightening screw
It can be rotated with screw, toner screw or off normal will not be caused, save operating time, the operation for reducing medical worker is difficult
Degree.
Brief description of the drawings
Attached drawing 1 is the structure diagram of the utility model.
Attached drawing 2 is the structure diagram of the folder cylinder of the utility model.
Attached drawing 3 is the structure diagram of the rotation clamping piece of the utility model.
Embodiment
1~attached drawing 3 is described below the utility model below in conjunction with the accompanying drawings.
As shown in FIG. 1 to 3, the utility model includes clamp handle 1, arc tong arm 4, folder cylinder 5, rotation clamping piece 2, the left side
Right clamp handle 1 is hinged by hinge shaft 3, and the rear end of clamp handle 1 is equipped with finger ring 6, and 1 end of clamp handle of 3 front end of hinge shaft is equipped with arc
Tong arm 4, the end of arc tong arm 4 are equipped with semicircular folder cylinder 5, rotation clamping piece 2 are equipped with folder cylinder 5.The present apparatus uses jaw type
Structure, 6 opening and closing gripper clamp of finger ring is inserted into by finger, easy to use, equipped with arc tong arm 4, when clamping rotary screw, no
Surgical field of view can be blocked, surgical procedure will not be caused to interfere, during gripper clamp pinching screw at left and right sides of semicircular folder
Cylinder 5 can close to form complete annular, and the inner cavity of left and right folder cylinder 5 can communicate, and rotate 2 pinching screw of clamping piece, and spiral shell is tightened in rotation
It can be rotated during nail with screw, screw will not loosen in rotary course, firm grip, and screw will not fall off or offset side
To, after screw rotation is screwed into most, screw can be unclamped, it is easy to use, it is time saving and energy saving, operating time is saved, reduces doctor
Business personnel tighten the operation difficulty of screw.
The rotation clamping piece 2 is made of intermediate plate 21, connecting rod 22, support shell 23, ball 24, and the inner side of the folder cylinder 5 is equipped with
Sliding groove 7, connecting rod 22 are inserted in sliding groove 7, are pressed from both sides 22 end of connecting rod in cylinder 5 and are equipped with support shell 23, ball 24 is housed in support shell 23,
22 other end of connecting rod is equipped with intermediate plate 21.Rotation clamping piece 2 can will ask shell 23 and ball 24 to load in folder cylinder 5 by sliding groove 7,
During 21 pinching screw of intermediate plate, ball 24 is withstood on folder 5 inner wall of cylinder, when screw is tightened in rotation, 21 pinching screw of intermediate plate, and ball 24
It can be rolled between support shell 23 and folder 5 inner wall of cylinder, connecting rod 22 can be rotated along sliding groove 7 with screw, so that rotating clamp
Hold piece 2 to rotate with screw, during screw-driving, rotation clamping piece 2 will not unclamp screw, and firm grip, will not cause screw
Come off or screw off normal, it is easy to use, save operation time.
In use, by the downside of the nut for rotating 2 pinching screw of clamping piece, rotation then is put to indexing and tightens screw, works as spiral shell
Nail be not screwed into position only remain rotation 2 clamped position of clamping piece when, open clamp handle 1, will rotation clamping piece 2 open disengaging screw, after
Continue screw-driving.
