Description
Technical field
The present invention relates to the bone taking device of a kind of bone surgery, experiment usefulness, especially shell and the convenient means of the spongy bone that reveals about periosteum being cut, for after obtaining spongy bone, being smashed again or cut to pieces little bulk in order to the application in orthopaedics implantation surgery or the experiment.
Background technology
In the running of medical care system, generally not from Prevention is better than cure, especially pay attention to most prevention infection in the operation with bone surgery, if because accidentally infecting, it will cause the healing difficulty increase of fracture, to patient body also quite consume.
Clinical orthopaedics has many different situations, such as: fracture, dislocation, arthritis, congenital distortion, tumor, degenerative disorders etc., some patient's condition can adopt conservative treatment, as take medicine or rehabilitation gets final product, but some patient's condition still needs active treatment can reach the purpose that the patient's condition is improved, as operates on operative treatment, displacement or transplant operation etc.
The bone transplant operation is that the skeleton (for the bone place) that will obtain is from elsewhere transferred to another position (bone grafting place).Traditionally, the purpose of employing bone grafting is to promote the healing situation of skeleton, so that enough intensity to be provided, as promote the firm healing of fracturing, arthrodesis, spinal fusion is filled the reconstruction etc. of cavity, tumor resection or the wound limbs of the tumor that cuts bone, and makes the sufferer limbs have good function.
And the above-mentioned bone mode of getting can be divided in vivo and two classes in vitro; In vivo get bone, namely there is sponge bone place to get bone in human body, its acquisition place is many at tibia front end or ilium ridge place, for knocking the os osseum on surface open separation first, expose the sponge bone and dug out and collect for subsequent use, it is limited that the bone that this mode can be taken owing to sufferer is afterwards transplanted number of blocks, and cause easily inflammation or complication, therefore develops separately the technology such as live body treatment with external measures bone.
Live body treatment with external measures bone: namely so-called bone separates the parent from human body, but still can continue to cultivate survival, and can be provided as and mend the bone use, Here it is gets " bone bank " (BONE BANK) deposits bone and comes live body treatment with external measures bone as bone grafting, present alleged " bone bank " of frozen bone bank (BONE BANK) i.e. is the freezing cabinet of a 40 degrees below zero, its function is: can be with the bone that downcuts, again via the screening of infectious disease and give freezing, dry, add after the strict processing of the multiple formality such as radiation give frozen, reduce its antigenicity, to reduce rejection, and determine without just using behind the pathogenic infection, its frozen bone namely is an aseptic bone rigid piece after taking-up, very ice-cold and hard, generally after taking-up, be not suitable for using immediately, decorticate bone and the stripping and slicing of also need being thawed can be used.
And the techno-absence of live body treatment with external measures bone is after taking out bone by bone bank now, and must can get bone via the supervisor that thaws, but this program takes 15～20 minutes at least, and must constantly change deionized water in the process to reduce osteocyte death or to infect, more need afterwards to get cortical bone manually progressively to cut, can cut or fragmentation spongy bone.
In addition, in the operation of now cartilage, also can be cut by bone surface and be made for In vitro culture after getting, directly plant go back to the affected part after the cultivation or be made for organizational project and use, but as aforementioned program, mostly be by manually progressively cutting the mode of getting, time and effort consuming not only, and more increase the danger that antibacterial infects.
So how to improve for this above-mentioned disappearance, for the present inventor for desiring most ardently the purpose that reaches, benefit with this and to execute patient and vast sufferer.
Summary of the invention
The object of the invention is to design a kind of bone device of getting that can use fast and reduce the antibacterial infection chance.
Be a kind of bone device of getting based on above-mentioned purpose the present invention, it comprises: one cuts osteon, a gear unit and a pulverizing unit;
This cuts osteon, this cut osteon be tubular and in be provided with one first accommodation space, and these two ends of cutting osteon have respectively a link and a bearing end;
This gear unit, this gear unit be tubular and in be provided with one second accommodation space, and the two ends of this gear unit are respectively equipped with one and cut epiphysis and a pulverizing end, this second accommodation space links setting for a power unit and at least one rotating unit, this cuts epiphysis and this link of cutting osteon links setting, and this is cut epiphysis and links and to be provided with one and to cut the osteotome tool and be located in this first accommodation space, and this pulverizings end then binding is provided with a crushing knife tool;
This pulverizing unit, this pulverizing unit be tubular and in be provided with one the 3rd accommodation space, the 3rd accommodation space is installed with for this crushing knife tool, and the two ends of this pulverizing unit have respectively a link and a blind end, and this pulverizing unit is pulverized end binding setting by this link and this.
Rely on technique scheme, the present invention is a kind of bone device of getting, its bone to be got puts and is placed in this this first accommodation space of cutting osteon, and cut the osteotome tool with this and contact, and by this gear unit transmission, bone being cut the bone program, wait cutting after the bone program finishes, spongy bone is taken out and is placed in this pulverizing unit, carry out block or pulverization program with this crushing knife tool again.
The advantage that the present invention has is: use not only can integral body carries out disinfection, and for the freezing bone that is taken out by bone bank, can directly cut easily the stripping outer cortical bone and capture in the bone spongy bone use for operative treatment, in this way, can actively reduce expending of manpower and time, more can significantly reduce the chance that antibacterial infects, operation quality and front and back for the patient all can reach perfect looking after.
