Description

Bone anchoring device
Technical field
The invention relates to a kind of bone anchoring device, particularly one and there is coating unit and expanding unit, the bone anchoring device launching Yu shrink can be carried out.
Background technology
Carrying out pouring into or filling in the operation of medical implant in skeleton, modus operandi common at present has following several:
Mechanical type Counterboring apparatus (such as United States Patent (USP) 20110196494,20110184447,20100076426,20070067034,20060009689,20050143827,20220052623,6354995,6676665) is utilized to carry out skeleton reaming, a space is produced in skeleton, after completing reaming, Counterboring apparatus is taken out, then put into coating unit again, then carry out the operation pouring into or fill in medical implant.This kind of modus operandi has following shortcoming: mechanical type Counterboring apparatus squeezes broken spongy bone (cancellous bone) fragment when reaming, often fall in mechanical type Counterboring apparatus, this mechanical type Counterboring apparatus is blocked, cause first assembly of reaming cannot regain (recovering the state of most shrinking), cause whole mechanical type Counterboring apparatus to be stuck in reaming position, cannot take out.
Filled type Counterboring apparatus (such as United States Patent (USP) 5972015,6066154,6235043,6423083,6607544,6623505,6663647,6716216) is utilized to carry out skeleton reaming, a space is produced in skeleton, again Counterboring apparatus is taken out after completing reaming, then put into coating unit, then carry out the operation pouring into or fill in medical implant.Because filled type Counterboring apparatus is mostly that a balloon is put into skeleton, utilize high pressure, liquid (such as water) is poured into balloon (according to different demand, use balloon miscellaneous) in, make balloon expansion, to push the spongy bone in skeleton, reach the object of reaming; Such as, but this apparatus/method has shortcomings: this balloon must be connected with filling mouth (nozzle), therefore, when high pressure pours into liquid, balloon may be caused by the phenomenon of filling with mouth and coming off, the situations such as balloon breaks even may be had to occur.
When not reaming in advance, directly coating unit put into skeleton and pour into medical implant, pressure when utilizing medical implant to be poured into coating unit, reaches the effect strutting skeleton.This kind of coating unit, when pouring into medical implant, has effect (such as TaiWan, China patent 1321467,201112995 of Counterboring apparatus and bone anchoring device simultaneously; United States Patent (USP) 6248110), or even give up coating unit, directly utilize a device for casting that medical implant is poured into operative site, to strengthen fixing (such as the United States Patent (USP) 5514137) of operative site.This kind of modus operandi has following shortcoming: owing to first not carrying out reaming, therefore cannot control scope when pouring into accurately, makes the direction after having poured into originally may expect that different situations occurs from doctor; In addition, even may appear at after filling with medical implant, find that this coating unit does not prop up skeleton completely, or there is medical implant to flee everywhere in skeleton, flow out that outer, that slurry formula medical treatment implant even the occurs concentration of skeleton is too rare or granular size is too small, the situations such as skeleton cannot be strutted smoothly when making to pour into medical implant, thus greatly reduce due effect originally.
Mechanical type Counterboring apparatus is used (such as United States Patent (USP) 20120071977,20110046739,20100069913,20100217335,20090234398,20090005821) as bone anchoring device, skeleton is implanted at mechanical type Counterboring apparatus, and after strutting skeleton, namely the perfusion of medical implant is carried out, allow the coated mechanical type Counterboring apparatus of medical implant, and after perfusion completes, by mechanical type Counterboring apparatus and medical implant together indwelling in human body.This kind of modus operandi, owing to not having coating unit, therefore effectively cannot control the flow direction of medical implant, and medical implant may be fled everywhere in skeleton, even likely flows out outside skeleton; In addition, medical treatment implant cannot be effective and complete coated mechanical type Counterboring apparatus, likely cause mechanical type Counterboring apparatus slowly by the state launched completely, be shrunk to the state do not launched completely, thus, skeleton is namely not softened completely, namely loses bone anchoring device object originally.
Applicant once proposed a kind of bone anchoring device (No. 101139150, TaiWan, China application for a patent for invention case), it utilizes the coated expanding unit of coating unit, effectively prevent when reaming crowded broken cancellous bone chips from falling in expanding unit, allow expanding unit can launch and shrink to carry out reaming in skeleton.In addition, in time pouring into medical implant, this device effectively can control the scope of medical implant perfusion, medical implant is avoided to run helter-skelter in skeleton, and after having poured into, the coated expanding unit of medical implant can completely, avoids expanding unit to have the possibility of contraction.But the structure comparatively unification of the expanding unit of this kind of bone anchoring device, because the bone hardness of each patient and skeleton mode of subsiding is neither identical, this kind of expanding unit also cannot carry out corresponding adjustment for different status of patient.Moreover, find in implementation process: when this kind of bone anchoring device uses on the patient that bone hardness is higher, it struts effect not as expected.Therefore, the present invention is this device of improvement, to adapt to the situation of different patient.
Summary of the invention
For the foregoing reasons, the present invention is the deployed configuration utilizing the coated expanding unit of a coating unit, make bone anchoring device when reaming is carried out in operation, effectively prevent crowded broken cancellous bone chips from falling in expanding unit, enable expanding unit successfully launch in skeleton by this and shrink to carry out reaming, adjusting the direction of reaming or the size of reaming scope.In time pouring into medical implant, this coating unit effectively can control the scope of medical implant perfusion, avoids medical implant to run helter-skelter in skeleton, and after having poured into, medical implant can completely fills expanding unit, avoids deployed configuration to have the possibility of contraction; And have a small amount of or medical implant of part can ooze out from the hole of coating unit, to be combined into one with bone trabecula.In addition, bone anchoring device of the present invention is through arranging multiple deployed configuration on coating unit, not only can increase the intensity of expanding unit, make expanding unit can support the harder skeleton of bone hardness, more can by the adjustment length of each deployed configuration and arrangement mode, deal with various different skeleton and to subside situation.
