Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example (b): as shown in the attached drawings 1 to 4, the positioning tool for the orthopedic operation of the valgus osteotomy of the foot mother comprises a positioning cutting block 1 and is characterized in that: the positioning and cutting block 1 comprises an inner fixing arm 11 and an outer fixing arm 12, the inner fixing arm 11 comprises a short-distance inner side arm 111 and a long-distance inner side arm 112, the outer fixing arm 12 comprises a short-distance outer side arm 121 and a long-distance outer side arm 122, the short-distance inner side arm 111 and the long-distance inner side arm 112 are integrally arranged in an angle mode, the short-distance outer side arm 121 and the long-distance outer side arm 122 are arranged in parallel relative to the short-distance inner side arm 111 and the long-distance inner side arm 112, a short-arm cutter groove 21 is formed between the short-distance inner side arm 111 and the short-distance outer side arm 112, a long-arm cutter groove 22 is formed between the long-distance inner side arm 121 and the long-distance outer side arm 122, the short-arm 21 and the long-arm cutter groove 22 form a cutting positioning cutter groove 2, the cutting positioning cutter groove 2 has an inclination angle, the short-arm cutter groove 21 is communicated with the long-, the long-distance inner side arm 112 and the long-distance outer side arm 122 are connected at one end, and the inner fixing arm 11 and the outer fixing arm 12 are provided with positioning holes 3.
The positioning hole 3 comprises a shaft positioning hole 31 and an arm positioning hole 32, the shaft positioning hole 31 comprises an outer side wall shaft positioning hole 312 and an inner side arm shaft positioning hole 311, and the arm positioning hole 32 is oppositely arranged on the inner fixing arm and the outer fixing arm 12. The shaft positioning holes 31 can determine the cutting position, so that the purpose of cutting and positioning is achieved, the two shaft positioning holes 31 of the inner arm shaft positioning hole 311 and the outer arm shaft positioning hole 31 can meet the requirements of bone cutting at different positions, and the inner arm shaft positioning hole 311 can be used when the outer arm shaft positioning hole 31 cannot be fixed on a bone.
The outer arm shaft positioning hole 31 is formed at the connection position of the short-distance outer arm 121 and the long-distance outer arm 122. The fixture is arranged at the joint of the short-distance outer side arm 121 and the long-distance outer side arm 122, so that the whole fixture can be effectively adjusted in angle, and the fixture can be fixed on a bone. The inner arm shaft positioning hole 311 is formed at the connection between the short-distance inner arm 111 and the long-distance outer arm 122. The installation at the junction of the short-distance inner side arm 111 and the long-distance inner side arm 112 can effectively enable the whole body to be adjustable in angle, and the fixture can be fixed on the foot skeleton. In general, only one of the outer arm shaft positioning hole 31 and the inner arm shaft positioning hole 311 needs to be fixed, so that the shaft positioning hole 31 can be disposed.
The arm positioning holes 32 are formed in the short distance outer arm 121, the long distance outer arm 122, the short distance inner arm 111 and the long distance outer arm 122, and at least one further arm positioning hole 32 is formed in the short distance outer arm 121, the long distance outer arm 122, the short distance inner arm 111 and the long distance outer arm 122. The plurality of arm positioning holes 32 are formed in the short-distance outer side arm 121, the long-distance outer side arm 122, the short-distance inner side arm 111 and the long-distance outer side arm 122, so that different conditions can be met, the cutting stages with different sizes and different angles can be adapted, and the purpose of arranging the arm positioning holes 32 can be achieved only by fixing at least two arm positioning holes 32 in a fixed mode.
The positioning hole 3 can be matched with a common orthopedic fixing device for use. The bone nail is generally in different sizes, and is respectively fixed in the shaft positioning hole 31 and the arm positioning hole 32, so that the purpose of fixing the tool at the operation part can be achieved, the tool cannot be randomly changed in the cutting process, the smooth operation of the bone cutting operation is ensured, and the occurrence of medical accidents is reduced.
The cutting locator groove 2 is inclined toward the outer fixing arm 12. Generally, the incision of the orthopaedics for the valgus osteotomy of the foot needs to cut a certain inclination angle so as to meet the aim of adjusting the foot bones after the incision, but the inclination angle of the incision is not very large and is generally maintained between 0 degree and 45 degrees, and the same inclination angle is used in a specific operation in the orthopaedics for the valgus osteotomy of the foot, so the adjustment of the incision inclination angle is not needed in general.
The cutting positioning knife groove 2 can be matched with a bone cutting device commonly used in the orthopaedics of the valgus osteotomy of the foot mother. The foot bone cutting device commonly used in the existing orthopedic operation of the valgus osteotomy of the foot mother is provided with a cutting moment and a osteotome, generally, points are drilled first, and then the points are connected with one another to achieve the purpose of cutting the bone, so if the cutting positioning knife groove 2 is not used for limiting the cutting inclination angle, the problem of angular deviation is likely to occur to doctors without abundant clinical experience and work experience.
The positioning cutting block 1 is of an integrated metal structure. Adopt integral type metal construction can guarantee integrality on the one hand, if adopt many parts package assembly, appear very probably long-time use the back, appear becoming flexible between the frock cooperation and rock the problem, prevent to appear cutting inclination, cutting vestige change when using, do not conform to the operation requirement, can not reach the purpose of operation.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
