Abstract
The invention discloses a device for taking bone cement out of marrow cavities. The device comprises a tubular drill bit and a driving device, the driving device is connected with the drill bit and drives the drill bit to rotate around the axis of the drill bit, and multiple protruding excavation teeth are arranged at the top of the pipe wall of the front end of the drill bit, wherein the excavation teeth surround the pipe wall. The device has the technical advantages that a transmission rod is connected and can change the direction at will to be adapted to different types of marrow cavities. A head of a tubular saw blade is inclined to the inner side, so that the head of the tubular saw blade can avoid bone cortex, only the bone cement is cut in the advancing and cutting processes, and the bone cortex cannot be damaged. The bone cement which is cut down is moved upward, squeezed and stored in a tubular storage tube. When the bone cement is taken out completely or stored to be full, the storage tube is provided with a squeezing device, and aggregated bone cement fragments can be squeezed out one time.
Description
Technical field
The present invention relates to medical instruments field, refer more particularly to the pulp cavity bone cement extractor of the femur used in the middle of hip revision operation.
Background technology
Hip revision is performed the operation: hip revision operation is the common surgical of joint surgery, and after being mainly used in hip replacement, Prosthesis related infections loosens or the patient of aseptic loosening.Along with the arrival of Chinese aging society and the development of joint surgery, the patient needing row hip revision to perform the operation increases year by year.Revision procedure difficulty is large, if the type femoral bone end prosthesis that previous operation uses is bone cement prosthese, in overhaul technology, in femoral bone cavitas medullaris, the cleaning of original bone cement and taking-up are a major challenge.
In overhaul technology, the necessary thoroughly cleaning of bone cement that femoral bone cavitas medullaris is residual, existing bone cement removal equipment comprises: pulp cavity round bur, pulp cavity directly bore, curet, pulp cavity osteotome, pulp cavity finger pin, splitting cutter, nucleus pulposus clamp etc.There is Railway Project in existing apparatus, and the first, drill bit is solid round bur or directly bores, can only cement in crush and grind pulp cavity, causes pulp cavity local pressure excessive, femoral cortex perforation or fracture easily occur.The second, connecting rod is rectangular stiff rod, is unfavorable for turning to, and cause easily grinding during drill bit burr in the femoral shaft cortex of local, the good guider of neither one can regulate burr direction, causes femoral cortex to be bored a hole or fracture.In addition, existing apparatus, while destruction pulp cavity bone cement, can not take out easily, needs to change apparatus and again takes out, and cement block may be caused to move to femoral bone cavitas medullaris far-end.
Because femoral bone cavitas medullaris is deep narrow, the hard and locked engagement of part bone cement, in femoral cortex, is easy to cause the destruction of femoral cortex by during existing apparatus cleaning in art, even fracture of shaft of femur of boring a hole.Once there is femoral cortex perforation or fracture, greatly can increase operating time, increase operative hemorrhage and cause the fixing difficulty of jointing repair prosthesis, affect surgical effect.Therefore, how safer sooner the original bone cement in cleaning femoral bone cavitas medullaris be difficult point and the key of hip revision operation.
