Abstract
The invention relates to the technical field of medical devices, in particular to a splenial bone implanting handle. The splenial bone implanting handle consists of a force-bearing cap, a grab handle, threads, a fastening nut, a shrink cylinder and deformation joints. The grab handle is a cylinder with the thread on the side wall at the lower end, the flat cylindrical force-bearing cap which is integrated with the grab handle into a whole is arranged at the upper end of the grab handle, and the cylindrical shrink cylinder which is integrated with the grab handle into the whole and has conicity which is small at top and big at bottom on the outer wall is arranged at the lower end of the grab handle. The thread is arranged on the outer side wall of the shrink cylinder. Four deformation joints are uniformly distributed on the outer side wall of the shrink cylinder, and the width of each deformation joint is larger than the wall thickness of the deformation joint by three times. The fastening nut which is combined with the grab handle through the thread is sheathed on the junction of the grab handle and the shrink cylinder. The splenial bone implanting handle has the functions of fastening and loosening a bone block at appropriate time, and can lead the operation to be simpler and more convenient and lead the surgery to have higher reliability and safety.
Description
Technical field
The present invention relates to technical field of medical instruments, particularly relate to a kind of Splenial bone implanting handle.
Background technology
Usually need bone grafting in bone surgery, plant bone mass can be fixed preferably in order to make, and needs to adopt a kind of Splenial bone implanting handle, and it is made of handle and the support and the location-plate that are positioned at the handle two ends.The shortcoming of this device is that it is merely able to the bone piece is played the pushing effect, does not have function in good time fastening and that unclamp the bone piece, therefore through regular meeting location-plate and the situation that the bone piece slips away takes place in the process of bone grafting, has increased the difficulty of operating like this.
Summary of the invention
The present invention is for solving the deficiencies in the prior art, provides a kind of energy fastening in good time and unclamp the Splenial bone implanting handle of bone piece.
The scheme that solves the technology of the present invention problem is: Splenial bone implanting handle is made of force-bearing cap, lever, screw thread, clamp nut, shrink cylinder and movement joint.Lever is the threaded cylinder of lower end side cornice, the upper end of lever be with lever be holistic, flat cylindrical force-bearing cap, the lower end of lever be with lever be columnar shrink cylinder holistic, that outer wall has up-small and down-big tapering.On the lateral wall of shrink cylinder screw thread is arranged.There are four movement joints that are evenly distributed the lateral wall of shrink cylinder, and the width of every movement joint is greater than three times of the movement joint wall thickness.The junction of lever and shrink cylinder be with lever with the bonded clamp nut of screw thread.
Adopt such scheme, can receive following effect:
During operation, earlier an end of bone piece is put into shrink cylinder, rotate clamp nut again, make it to move down, because shrink cylinder has up-small and down-big tapering, under the constraint of clamp nut, shrink cylinder just clamps the bone piece.During bone grafting, hand-held lever, with bone block alignment sutura crack, the force-bearing cap that pounds with a hammer can be knocked in sutura with the bone piece.
The present invention not only can play the pushing effect to the bone piece, also has function fastening in good time and that unclamp the bone piece simultaneously, therefore can avoid that location-plate takes place with the situation that the bone piece slips away in the process of bone grafting, make operation easier, also making performs the operation has higher reliability and safety.
Description of drawings
Fig. 1 is a cross-sectional view of the present invention;
Fig. 2 is the bottom plan view of shrink cylinder.
Among the figure: 1. force-bearing cap 2. levers 3. screw threads 4. clamp nuts 5. shrink cylinder 6. movement joints
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
Splenial bone implanting handle is made of force-bearing cap 1, lever 2, screw thread 3, clamp nut 4, shrink cylinder 5 and movement joint 6.Lever 2 is cylinders that the lower end side cornice has screw thread 3, and the upper end of lever 2 is to be holistic, flat cylindrical force-bearing cap 1 with lever 2, and the lower end of lever 2 is to be the columnar shrink cylinder 5 holistic, that outer wall has up-small and down-big tapering with lever 2.On the lateral wall of shrink cylinder 5 screw thread is arranged.There are four movement joints 6 that are evenly distributed the lateral wall of shrink cylinder 5, and the width of every movement joint 6 is greater than three times of movement joint 6 wall thickness.The junction of lever 2 and shrink cylinder 5 be with lever 2 with the bonded clamp nut 4 of screw thread.
During operation, earlier an end of bone piece is put into shrink cylinder 5, rotate clamp nut 4 again, make it to move down, because shrink cylinder 5 has up-small and down-big tapering, under the constraint of clamp nut 4, shrink cylinder 5 just clamps the bone piece.During bone grafting, hand-held lever 2, with bone block alignment sutura crack, the force-bearing cap that pounds with a hammer 1 can be knocked in sutura with the bone piece.
Claims (1)
1. Splenial bone implanting handle, by force-bearing cap, lever, screw thread, clamp nut, shrink cylinder and movement joint constitute, it is characterized in that: lever is the threaded cylinder of lower end side cornice, the upper end of lever be with lever be holistic, flat cylindrical force-bearing cap, the lower end of lever be with lever be holistic, outer wall has the columnar shrink cylinder of up-small and down-big tapering, on the lateral wall of shrink cylinder screw thread is arranged, there are four movement joints that are evenly distributed the lateral wall of shrink cylinder, the width of every movement joint is greater than three times of the movement joint wall thickness, the junction of lever and shrink cylinder be with lever with the bonded clamp nut of screw thread.
