Abstract
A kind of bone surgery punching sight, is provided with handle, is provided with bending link arm in one end of handle, be provided with location hook in link arm front end, be provided with supporting projections, between supporting projections and location hook, form pit in the position of the inner side 8mm ~ 30mm of location hook; Be provided with the pilot hole run through in handle, be provided with long straight guide pipe, the front end of guide pipe and the retaining wall vis-a-vis of pit bottom surface through pilot hole is supporting.This punching sight makes the drilling operation in bone surgery process become simply accurate, safe and reliable, and structure of the present utility model is simple, without the need to Electric control and measuring system, only need outlet and the entrance of the pit of the application's product and guide pipe being distinguished alignment settings boring, entering bit bore along guide pipe can accurately hole or squeeze into Kirschner wire.
Description
Technical field
This utility model relates to medical apparatus and instruments, is a kind of punching sight of bone surgery specifically.
Background technology
The action need of threading a needle of bone surgery uses boring bar tool to carry out drilling operation that is oblique to skeleton or vertical direction in the appointed part of skeleton in advance, accurate positioning is needed after muscular tissue being peeled off during boring, really the muscle on opposite or the tissue such as neural can not be injured after fixing a point to drill to skeleton with position accurately and angle, the accuracy of operation only relies on the experience of doctor at present, and during operation, the assurance difficulty of accuracy is larger.
Summary of the invention
Technical problem to be solved in the utility model solves the problem, and provides a kind of bone surgery punching sight, make the drilling operation of orthopaedics become easy, accurate, safe and reliable.
Described bone surgery punching sight, it is characterized in that: be provided with handle, bending link arm is provided with in one end of described handle, location hook is provided with in the front portion of described link arm or front end, be provided with supporting projections in the position of the inner side 8mm ~ 30mm of described location hook, between described supporting projections and location hook, form pit; Be provided with the pilot hole run through in described handle, be provided with long straight guide pipe, the front end of described guide pipe and the retaining wall vis-a-vis of described pit bottom surface through described pilot hole is supporting.
A kind of embodiment is, the end face of described guide pipe and described pilot hole is circular, the external diameter 0.2mm ~ 1.5mm less of the internal diameter of pilot hole of guide pipe.
Another kind of embodiment is that the outer surface of described guide pipe and the inner surface of described pilot hole are provided with the screw thread complemented one another.
Described guide pipe is provided with Multiple Type, and the guide pipe of different model is provided with different internal diameters, to adapt to drill bit or the Kirschner wire of different-diameter.
Further, the pilot hole position of described handle is provided with outstanding protecting stand.
This utility model makes the drilling operation in bone surgery process become simply accurate, safe and reliable, and structure of the present utility model is simple, without the need to Electric control and measuring system, only need the two ends by the pit of the application's product and the boring of guide pipe difference alignment settings, enter bit bore along guide pipe and get final product accurate contraposition.And the design of pit and retaining wall makes the drilling tool that drills to fall through sense due to the load generation that suddenly disappears, and due to the protection of retaining wall, drill bit can not be damaged to the tissue such as muscle, nerve in front.Guide pipe Activities Design can instantaneously changing guide pipe, uses the guide pipe of suitable inner diameter, to coordinate drill bit or the Kirschner wire of different-diameter.Protecting stand makes pilot hole be extended, and enhances the stability of guiding, and makes the hands holding handle because the isolation of protecting stand can not directly touch guide pipe and affect guiding.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In figure: 1-link arm, 2-handle, 3-guide pipe entrance, 4-pilot hole, 5-protecting stand, 6-pit, 7-guide pipe, 8-location hook, 9-supporting projections, 10-retaining wall.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further illustrated: as shown in Figure 1, described bone surgery punching sight, be provided with handle 2, bending link arm 1 is provided with in the upper end of described handle, location hook 8 is provided with in the front end of described link arm 1, location hook bends to the inside, is provided with supporting projections 9 in the position of the upside 8mm ~ 30mm of described location hook, forms pit 6 between described supporting projections and location hook.Link arm part in figure from front end shank portion in one's hands thicker gradually, handle portion diameter is comparatively large, is convenient to grip, front end is deep in muscular tissue, diameter is less, and setting material makes link arm have enough rigidity, and can not there be unstable variation at position, front end by opposite handle after fixing.
The pilot hole 4 run through is provided with in described handle 2, long straight guide pipe 7 is provided with through described pilot hole is supporting, as the embodiment in figure, the end face of described guide pipe and described pilot hole is circular, the external diameter 0.5mm less of the internal diameter of pilot hole of guide pipe, the front end of described guide pipe and retaining wall 10 vis-a-vis of described pit 6 bottom surface.Only need the two ends by the pit of the application's product and the boring of guide pipe difference alignment settings during use, enter drill bit along guide pipe, carry out drilling operation, get final product accurate contraposition.And the design of pit and retaining wall makes the drilling tool that drills to fall through sense due to the load generation that suddenly disappears, and due to the protection of retaining wall, drill bit can not be damaged to the tissue such as muscle, nerve in front.
Described guide pipe is provided with Multiple Type, and different guide pipes is provided with different internal diameters, to adapt to drill bit or the Kirschner wire of different-diameter.The Activities Design of guide pipe can make guide pipe instantaneously changing, uses the guide pipe of suitable inner diameter, to coordinate drill bit or the Kirschner wire of different-diameter.
A kind of design embodiments can be that the outer surface of described guide pipe and the inner surface of described pilot hole are provided with the screw thread complemented one another.Guide pipe, by being threaded into, makes coordinating comparatively closely between guide pipe with pilot hole, and is not easily changed angle by the collision of accidental external force, and axial movement also not easily occurs.
The pilot hole position of described handle is provided with outstanding protecting stand 5.Protecting stand makes pilot hole be extended, and enhances the stability of guiding, and makes the hands holding handle because the isolation of protecting stand can not directly touch guide pipe and affect guiding.
