Description
Technical field
The present invention is relevant a kind of vertebra Counterboring apparatus, a kind of vertebra Counterboring apparatus with coating unit.
Background technology
In bone surgery, in order to meet these it is often necessary to first carry out reaming at vertebra, the most common orthopaedics reaming operation has two kinds: a kind of
To utilize mechanical type Counterboring apparatus to carry out reaming, such as: United States Patent (USP) 20110196494,20110184447,
20100076426、20070067034、20060009689、20050143827、20220052623、6354995、6676665
Deng, TaiWan, China patent 585091, I318110 etc., but the problem of above-mentioned technology maximum is: squeeze broken spongy bone during reaming
(cancellous bone) fragment, often falls in Counterboring apparatus, makes described Counterboring apparatus block, and causes first assembly of reaming
Cannot regain (recovering the state most shunk), the most whole Counterboring apparatus is stuck in reaming position, it is impossible to take out.
Another kind is to utilize filled type Counterboring apparatus, the such as series of products of U.S. Kyphon company, Kyphon company
Series of products are balloon miscellaneous, to coordinate different demand, the Patents of its device itself such as: United States Patent (USP)
5972015,6066154,6235043,6423083,6607544,6623505,6663647,6716216 etc., its using method
Patents such as: United States Patent (USP) 5972015,6048346,6235043,6248110,6280456,6440138,
6607544,6716216,6719761,6726691 etc..Combine Counterboring apparatus and the expanding method of opinion Kypon, nothing more than utilizing height
Pressure, pours into liquid (such as water) in balloon (according to different demands, use balloon miscellaneous), makes balloon expansion, to push
Spongy bone in vertebra, reaches the purpose of reaming.But said apparatus or method have shortcomings, such as: described balloon is necessary
Connect and fill mouth (nozzle), when therefore high pressure pours into liquid, be likely to result in balloon by filling the phenomenon that mouth comes off, in some instances it may even be possible to have gas
The situations such as ball fractured occur, and its modus operandi is the most complex；Furthermore, for coordinating different demand, balloon must design inside
Limit resistance part divides (internal restraint) or outside limit resistance part to divide (external restraint), for example, see above-mentioned U.S.
State's patent 6066154, or the Counterboring apparatus of particular design, such as United States Patent (USP) 6235043 so that the manufacture of balloon and use phase
For to relatively difficult.
