Description
Technical Field
The utility model relates to a medical supplies field, concretely relates to multidirectional expanded steel sheet of rebuilding.
Background
At present, the steel plate is a reliable device for treating fracture clinically. There are many types of steel plates, including locking plates, reconstruction plates, anatomical plates, and the like. The deep grooves are formed between the bone plate holes of the reconstruction steel plate, so that the bone plate is subjected to shaping pre-bending on the plane by using a specially designed bone plate shaping tool, the shape is accurately changed to fit the shape of a bone, the reconstruction steel plate is suitable for fracture with a complex three-dimensional geometric shape and is mainly used for pelvis, acetabulum, clavicle, humerus far end, radicle and the like, but the strength of the reconstruction steel plate is greatly weakened after shaping, particularly after sharp bending; in addition, the steel plate has insufficient longitude and latitude length in the use process.
Disclosure of Invention
The to-be-solved technical problem of the utility model is how to overcome the not enough of prior art existence, provides a multidirectional expanded steel sheet of rebuilding.
The technical solution of the utility model is that: the utility model provides a multidirectional expanded rebuilt steel sheet, includes steel sheet and lower steel sheet, go up the steel sheet and all include integrated into one piece's fixed part and connecting portion with lower steel sheet, the fixed part is a plurality ofly, the fixed part is circular, tangent between the fixed part, it has the concave point to go up steel sheet fixed part downside equipartition, it has the through-hole to go up steel sheet fixed part center, down steel sheet fixed part upside equipartition have with concave point matched with bump, open threaded hole down at steel sheet fixed part center, go up the steel sheet fixed part with the diameter of steel sheet fixed part is the same down.
Furthermore, the number of the upper steel plate fixing parts is two, and the number of the lower steel plate fixing parts is two.
Furthermore, the number of the upper steel plate fixing parts is two, and the number of the lower steel plate fixing parts is three.
The reconstruction steel plate of the utility model adopts the staggered connection of the upper steel plate and the lower steel plate fixing part, extends according to the shape of the skeleton, can be tightly attached to the skeleton, does not have the condition that the longitude and latitude lengths of the steel plates are not enough, and is suitable for the fracture of complex three-dimensional geometric shapes; due to the occlusion of the concave points and the convex points of the fixing parts of the upper steel plate and the lower steel plate, the fixed connection of the lower threads of the connecting screws to the skeleton and the lower steel plate, and the pressing of the screw caps of the connecting screws to the upper steel plate, the reconstructed steel plate can be firmly fixed at the skeleton, the better strength is kept, and the problem of strength reduction of pre-shaping is avoided. The utility model discloses have potential market value.

Detailed Description
The following describes a multidirectional expandable rebuilt steel plate in detail with reference to the accompanying drawings and embodiments.
Example 1
As shown in fig. 1, 2 and 3, a multidirectional expandable reconstruction steel plate comprises an upper steel plate 1 and a lower steel plate 2, wherein the upper steel plate 1 and the lower steel plate 2 both comprise integrally formed fixing portions 11 and 21 and connecting portions 12 and 22, the fixing portions 11 and 21 are multiple, the fixing portions 11 and 21 are circular, the fixing portions 11 and 21 are tangent to each other, concave points 111 are uniformly distributed on the lower side of the upper steel plate fixing portion 11, a through hole 112 is formed in the center of the upper steel plate fixing portion 11, convex points 211 matched with the concave points 111 are uniformly distributed on the upper side of the lower steel plate fixing portion 21, a threaded hole 212 is formed in the center of the lower steel plate fixing portion 21, and the upper steel plate fixing portion 11 and the lower steel plate fixing portion 21 have the same diameter.
Further, there are two upper steel plate fixing portions 11 and two lower steel plate fixing portions 21.
Example 2
As shown in fig. 4 and 5, a multidirectional expandable reconstruction steel plate comprises an upper steel plate 1 ' and a lower steel plate 2 ', the upper steel plate 1 ' and the lower steel plate 2 ' both comprise integrally formed fixing portions 11 ', 21 ' and connecting portions 12 ', 22 ', the fixing portions 11 ', 21 ' are multiple, the fixing portions 11 ', 21 ' are circular, the fixing portions 11 ' and the fixing portions 21 ' are tangent, concave points are uniformly distributed on the lower side of the upper steel plate fixing portion 11 ', through holes 112 ' are formed in the center of the upper steel plate fixing portion 11 ', protruding points 211 ' matched with the concave points are uniformly distributed on the upper side of the lower steel plate fixing portion 21 ', threaded holes 212 ' are formed in the center of the lower steel plate fixing portion 21 ', and the diameter of the upper steel plate fixing portion 11 ' is the same as that of the lower steel plate fixing portion 21 '.
Further, there are two upper steel plate fixing portions 11 'and three lower steel plate fixing portions 21'.
In the use of the embodiment 1 of the present invention, as shown in fig. 3, a fixing portion 11 of the upper steel plate 1 is buckled with a fixing portion 21 of the lower steel plate 2, so that the concave point 111 and the convex point 211 are engaged, and the connecting screw is screwed into the through hole 112 and the threaded hole 212, so as to fixedly connect the upper steel plate 1 and the lower steel plate 2 to the bone; the other fixing portion 11 of the upper steel plate 1 may be connected to the fixing portion 21 of the other lower steel plate 2, and the other fixing portion 21 of the lower steel plate 2 may be connected to the fixing portion 11 of the other upper steel plate 1. Example 2 is the same in principle as example 1. As shown in fig. 5, the difference is that the other two fixing portions 21 'of the lower steel plate 2' may be connected with the fixing portions 11 'of the other one or two upper steel plates 1'.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and those skilled in the art can make many variations and modifications of the present invention without departing from the scope of the present invention as defined in the appended claims.
