Technical field
The utility model relates to a kind of orthopaedics medical instruments, and in particular to bone used in a kind of operation of foramen intervertebrale lens
Shovel.
Background technique
In foramen intervertebrale lens operation, causes pressure object that need to be removed decompression in some bones, use bone shovel, often to complete hand
Art.Existing bone shovel top is crescent, and cutting edge is positioned using the wedge angle at its both ends, is then dug deep superfluous.But its two
End wedge angle is easy to appear abrasion or deformation after a number of uses, and procedure efficiency is caused to reduce, or even bone shovel occurs and skid, and causes hand
Art risk.
Summary of the invention
The purpose of this utility model is to provide a kind of high-efficient, durable foramen intervertebrale lens are shoveled with efficient bone.
To achieve the goals above, the utility model includes handle, and operating stick, operating stick one end and handle are arranged on handle
Shovel head is arranged in connection, the other end, and the shovel head includes a curved edge, and shovel head further includes two anchoring points, and anchoring point is located at
The two sides of curved edge are anchored point level and are greater than the thickness of curved edge with the thickness in cutting edge vertical direction, are anchored point
Top lengthwise position is higher than the lengthwise position at curved edge any point, and two anchoring points are symmetrically set in curved edge two sides
It sets.
Preferably, the shovel head is wide at the top and narrow at the bottom, lower thick thin.
Further, the blind hole coaxial with handle is set on the handle, the operating stick is inserted into blind hole, and the one of handle
Side is equipped with sliding slot, and sliding slot is connected to blind hole, and fixed connecting rod in the operating stick, connecting rod is pierced by from sliding slot, vacant end
It is connect with transmission mechanism, the transmission mechanism pushes connecting rod to move reciprocatingly in sliding slot along handle axis direction.
Further, the transmission mechanism includes first connecting rod, second connecting rod, runner and speed reducer, and described first connects
The vacant end of bar and connecting rod is hinged, and the vacant end of second connecting rod one end and first connecting rod is hinged, and the other end is hinged with runner, subtracts
Fast machine driving runner rotation.
Preferably, the speed reducer is fixed in handle.
The beneficial effects of the utility model are that setting anchoring point is anchored the enlarged in thickness of point, can effectively improve bone shovel
Locating effect, improve procedure efficiency, and thicken anchoring point it is more durable.Setting transmission mechanism enables operating stick to do back and forth
Movement, the movement of frequency low-amplitude realize that automatically chisel cutting is made, and greatly improves working efficiency.

Specific embodiment
The utility model is described in detail with reference to the accompanying drawing.
As shown in Fig. 1 to 5, a kind of foramen intervertebrale lens are shoveled with efficient bone, including handle 10, and operating stick 20 is arranged on handle 10,
20 one end of operating stick is connect with handle 10, and shovel head 21 is arranged in the other end, which is characterized in that the shovel head 21 includes an arcuate blade
Mouth 212, shovel head 21 further include two anchorings points 211, and anchoring point 211 is located at the two sides of curved edge 212, it is horizontal to be anchored point 211
And it is greater than the thickness of curved edge 212 with the thickness in cutting edge vertical direction, the top lengthwise position of anchoring point 211 is higher than arc
The lengthwise position at 212 any point of cutting edge, and two anchoring points 211 are symmetrical arranged in 212 two sides of curved edge.
It in use, anchoring point contradicts vertebrae, can quickly position, then vertebrae is carried out using curved edge 212
Chisel is cut.It is anchored curved edge 212 at sharp disengaging itself, is positioned with the both ends blade tip in the prior art using crescent cutting edge
Difference, more sturdy and durable using independent anchoring point, effect is higher, and risk factor is lower.
Preferred embodiment, the shovel head 21 is wide at the top and narrow at the bottom, lower thick thin.Lower thickness wide at the top and narrow at the bottom is above thin to make shovel head more
It is sturdy and durable.
The blind hole coaxial with handle, the insertion of operating stick 20 blind hole are arranged on the handle 10 for preferred embodiment
In, the side of handle 10 is equipped with sliding slot 11, and sliding slot 11 is connected to blind hole, fixed connecting rod 22 in the operating stick 20, connecting rod
22 are pierced by from sliding slot 11, and vacant end is connect with transmission mechanism 30, and the transmission mechanism 30 pushes connecting rod 22 in sliding slot 11
It is middle to move reciprocatingly along 10 axis direction of handle.Transmission mechanism drives shovel head 21 automatically to carry out chisel to vertebrae and cuts, and is convenient for art
Person's operation, improves efficiency.
Preferred embodiment, the transmission mechanism 30 include first connecting rod 31, second connecting rod 32, runner 33 and slow down
Machine 34, the first connecting rod 31 and the vacant end of connecting rod 22 are hinged, the vacant end of 32 one end of second connecting rod and first connecting rod 31
Hingedly, the other end and runner 33 are hinged, and speed reducer 34 drives runner 33 to rotate.This mode can generate high frequency, by a narrow margin past
Multiple movement, cuts convenient for the chisel to vertebrae.
