Abstract
The utility model relates to the technical field of a medical appliance, in particular to a bone seam inserting device which is composed of a force bearing cap, a grab handle, a thread, a fastening unit, a retracting cylinder and deformation seams. The grab handle is a cylinder with the thread on the side wall at the lower end. The flat cylindrical force bearing cap is arranged at the upper end of the grab handle and forms a whole with the grab handle. The cylindrical retracting cylinder has certain taper with the upper part smaller and the lower part larger, is arranged at the lower end of the grab handle, and forms a whole with the grab handle. The thread is arranged in the outer side wall of the retracting cylinder. Four deformation seams are uniformly distributed on the outer side wall of the retracting cylinder, and the width of each deformation seam is three times larger than the wall thickness of each deformation seam. The fastening unit in threaded combination with the grab handle is sheathed at the connecting position between the grab handle and the retracting cylinder. The bone seam inserting device has the functions of fastening and loosening bones at proper time, is simpler as well as more convenient for operation, and can lead operations to be more reliable and safer.
Description
Technical field
This utility model relates to technical field of medical instruments, particularly relates to a kind of bone piece interpolation slit device.
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 bone piece interpolation slit device, 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.
The utility model content
This utility model is for solving the deficiencies in the prior art, provides a kind of energy fastening in good time and unclamp the bone piece interpolation slit device of bone piece.
The scheme that solves this utility model technical problem is: bone piece interpolation slit device 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.
This utility model 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 utility model;
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 utility model will be further described below in conjunction with drawings and Examples.
Bone piece interpolation slit device 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. bone piece interpolation slit device, 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.
