Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, the particularly a kind of fixture that is applicable to post-surgery skull and other osseous tissue that can dismantle.
Background technology
Traditional post-surgery skull fixing employing suture mode or special screw fix skull.And modern craniotomy operation is to bore a plurality of holes earlier on skull, then, again the skull between two holes is carried out annular cutting operation art.Obviously, traditional skull fixed form is not suitable for the fixing of the modern movable skull in craniotomy operation back.At present, have the post-surgery skull fixing device of various ways, be called the patent of invention of " fixer for loop after cranial bone operation " as the name of CN 1229081C bulletin; This device comprises: one regulates tie rod has a combining mechanism; Once stator combines with this adjusting tie rod; Stator has a through hole and can pass this adjusting tie rod on one, and combines with this adjusting tie rod with a combining mechanism, forms one and easily advances the combining mechanism that slides that difficulty moves back.And for example the name of CN200951105Y bulletin is called the utility model patent of " the fixing lock of a kind of skull "; Should include an adjusting lever by fixing lock, one is fixed on the following stator of adjusting lever bottom, and stator is arranged on the adjusting lever by an adjustable locking mechanism that slides on one.But these skull locking devices have deficiency: the retaining mechanism that has adopted Yi Jinnan to move back, locking force are transferred joint difficulty down, damage skull easily, in case fixing back just can not be dismantled the skull lock again, have increased the risk of carrying out the secondary operation of opening cranium greatly; Need must shear with special-purpose clamp the connecting rod of residue length with more aid during installation, and shear the out-of-flatness meeting and cause the scalp rubbing damage to suppurate, influence the postoperative healing.
Summary of the invention
The present invention provides a kind of fixture that is applicable to post-surgery skull and other osseous tissue that can dismantle in order to overcome the deficiency that above-mentioned skull fixator exists, and it is simple in structure, and is fixing reliable, mounts and dismounts quick, easy.
A kind of fixture that is applicable to post-surgery skull and other osseous tissue that can dismantle of the present invention, comprise locking plate, upper collet and lifting rod down, it is characterized in that: be provided with a perpendicular adjustable column above the infra locking plate, adjustable column is an integral body with following locking plate, the center of adjustable column is provided with a screwed hole, and the surface of adjustable column is provided with an outer locking structure; Be provided with a perpendicular adjusting tube below upper collet, regulating tube is an integral body with upper collet, the inwall of regulating tube be provided with one with the interior locking mechanism of the outer locking respective outer side edges on following adjustable column surface above the locking plate; Regulate the tube size and adapt,, increase constant intensity, be difficult for loosening slippage, easily healing to reduce the crack between skull with the width of opening the diameter in cranium hole or milling seam.Following locking plate, upper collet and lifting rod available metal or nonmetallic materials are made.Bottom at lifting rod is provided with external screw thread, and the adjusting tube that lifting rod passes below the upper collet cooperates with the screwed hole at following adjustable column center above the locking plate.
The described a kind of fixture that is applicable to post-surgery skull and other osseous tissue that can dismantle, it regulates the interior locking mechanism of tube inwall and the outer locking structure on adjustable column surface is anti-skidding ratchet structure or special-shaped snap arrangement.
The described a kind of fixture that is applicable to post-surgery skull and other osseous tissue that can dismantle, the outer locking structure that the surface of its adjustable column is provided with is an external screw thread, the interior locking mechanism that the inwall of adjusting tube is provided with is a female thread.Helicitic texture is best, is convenient to dismounting.
The described a kind of fixture that is applicable to post-surgery skull and other osseous tissue that can dismantle, locking plate and upper collet are the polygon of circular, oval or chamfering under it; The edge of following locking plate is provided with a plurality of lower tooths that are bent upwards slightly, and the edge of upper collet is provided with a plurality of reclinate slightly teeth of going up.Its role is to make down locking plate and upper collet to be fixed on reliably on the skull plate, avoid producing slippage.
The described a kind of fixture that is applicable to post-surgery skull and other osseous tissue that can dismantle, the top of its lifting rod is provided with one and rotates handgrip, and rotating handgrip is one section bending, middle part and lifting rod upper end cross bar connected vertically or disk.
Advantage of the present invention is: owing to retaining mechanism can fasteningly can be dismantled again, so, alleviated the risk of carrying out the secondary operation of opening cranium greatly; The aid that need use during installation and removal is few, and is not only fixing reliable, mount and dismount fast, easy, and needn't shear the connecting rod of residue length, can not cause the frictionally damage to scalp, helps postoperative and heals.
