Description
Technical field
The invention belongs to medical apparatus and instruments, be specifically related to a kind of acetabular bone osteotome。
Background technology
Human hip is a kind of spherical joint, comprises a spherical femoral head and a seemingly bowl-shape acetabular bone。Its joint formed for Thigh bone (femur) and pelvis, spherical top layer and bowl endosexine cover by smooth cartilago acetabularis, and it is minimum that synovial bursa film secreting mucus makes friction be reduced to。When hip joint produces pathological changes, cartilago acetabularis is no longer smooth, synovial bursae inflammation and atrophy, and joint can not as usual be gone slick again。When hip joint because degenerating, pathological changes or wound cause pain, stiff or deformation, even handicapped, it is impossible to during with medicine or other treatment method relief of symptoms, it will usually to replace artificial hip joint in the mode of operation for patient, make patient recover daily mobility。
Artificial hip prosthesis copies the structure of human hip, is inserted in femoral bone cavitas medullaris by prosthese shank, utilizes head to be formed with cotyla or prosthese metal cup and rotates, it is achieved the bending and stretching and moving of femur。Prosthese adopts the material manufactures such as titanium alloy, vitallium, pottery, rustless steel。The hip prosthesis no matter any material manufactures, all has corresponding service life, after reaching corresponding service life, it is necessary to take out prosthese in human body。
Hip revision operation generally adopts acetabular bone osteotome to take out acetabular component, existing acetabular bone osteotome is made up of the cambered blade of handle and the one end being arranged on handle, during use, hold handle to cut, the cartilago acetabularis near acetabular component is cut so that acetabular component separates with cartilago acetabularis and is removed by cambered blade one cutter one cutter。When existing acetabular bone osteotome uses, it is entirely and carries out cutting location by doctor is hand-held, it is not easy to control cutting position and cutting output, use inconvenience, after acetabular component cuts out, it is attached to the cartilago acetabularis variable thickness on acetabular component surface, and the efficiency taking out acetabular component is also low。
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is provided that a kind of easy to use and acetabular bone osteotome that efficiency is high。
The present invention is achieved through the following technical solutions: a kind of acetabular bone osteotome, including handle and be arranged on one end of handle, for cutting the cambered blade of acetabular bone, described handle is additionally provided with swivel head in one end of position set by corresponding cambered blade, and cambered blade is positioned at the outside of swivel head。
In such scheme, during use, cambered blade inserts the cartilago acetabularis outside acetabular component, and swivel head is placed in the groove of acetabular component, doctor's turning handle, swivel head carries out auxiliary positioning as center of rotation, cambered blade circles with swivel head for center of rotation, it is achieved the cartilago acetabularis outside acetabular component is cut so that acetabular component separates with cartilago acetabularis, then mentioning acetabular bone osteotome, acetabular component can be stayed to be jammed between cambered blade and swivel head and not fall out。Reaching cutting purpose by rotary handle mode, easy to use, rotation is turned around or can cut open the cartilago acetabularis around acetabular component after some circles, quickly removes acetabular component, and efficiency is high。
In order to reach the groove fit of swivel head and acetabular component, improving auxiliary positioning precision, above-mentioned swivel head is hemispherical。
In order to facilitate turning handle, above-mentioned handle is provided with handle away from the sidewall of the one end of position set by cambered blade。
Similarly, in order to facilitate turning handle, above-mentioned handle is provided with handle set away from an end of position set by cambered blade。
In order to simplify manufacturing process, convenient for assembly, above-mentioned handle is provided with fixing seat in one end of position set by corresponding cambered blade, and swivel head and cambered blade are individually fixed on fixing seat。
In order to ensure installation reliability, above-mentioned fixing seat offers breach in the fixed position of corresponding cambered blade, and one end that cambered blade is corresponding and fixing seat is connected is provided with the cutter head that the breach with fixing seat coordinates, and cutter head is connected with the wall portion of breach。
In order to facilitate the handling of blade assembly, the wall portion of above-mentioned cutter head and breach is connected by screw。
Similarly, in order to ensure installation reliability, above-mentioned swivel head and fixing seat are by Stud connection, and threadeding with swivel head in one end of stud, the other end of stud welds with fixing seat。
The present invention by installing cambered blade and swivel head in handle one end, and make cambered blade be positioned at the outside of swivel head, the other end arranges the handle facilitating rotatable handle, during use, cambered blade inserts the cartilago acetabularis outside acetabular component, swivel head is placed in the groove of acetabular component, doctor holds handle and band fixed handle rotates, swivel head carries out auxiliary positioning as center of rotation, cambered blade circles with swivel head for center of rotation along acetabular component, the cartilago acetabularis outside acetabular component is realized to cut, acetabular component is separated with cartilago acetabularis, then acetabular bone osteotome is mentioned, acetabular component can stay be jammed between cambered blade with swivel head and by together with mention。The present invention drives cambered blade to circle cutting purpose outside acetabular component by rotary handle, easy to use, and the thickness ratio that cuts cartilago acetabularis is more uniform, rotary handle one encloses or can cut open the cartilago acetabularis around acetabular component after some circles, can quickly removing acetabular component, efficiency is high。In order to adapt to different operation demands, the screw of swivel head and blade and Stud connection mode, it is simple to change swivel head and the blade of different size specification at any time, and then meet the taking-up demand of different size acetabular component。The acetabular bone knife structure of the present invention is simple, it is easy to clean。
