Description
Technical field
The present invention relates to fixed networks outside bone rehabilitation, correction field more particularly to bone rehabilitation, more specifically,
More particularly to a kind of step-less adjustment with guiding role is threaded a needle fixture.
Background technique
In the treatment of surgery bone-operating, when fixed device, is essential, and traditional fixed form generally uses steel plate
Also there is the therapeutic modality of the smaller outer fixation of wound now in interior fixation.Common external fixer is mainly Ilizarov
External fixator, Taylor's skeleton；Ilizarov technology runs through limbs and bone tissue using the thin Kirschner wire of more planes, and it is solid to connect annular
Determine device；Taylor doctor improves ILizarov external fixation system, and six telescopic extension rods are connected obliquely proximally and distally
It on ring, and can be rotated freely at tie point, as long as adjusting the length of a wherein extension rod, a ring will be relatively another
A ring changes position.The extension pole length that relatively lopsided parameter can be calculated using computer software, can imitate and appoint
What deformity constructs Taylor space frame in advance, is treated and corrected various simple or complicated fracture and deformity.Taylor's skeleton
It constitutes are as follows:
1, upper and lower two rings, are referred to as proximal loop and distal loop.
2, the extension rod of six adjustable length, and the length of each extension rod can directly be read.
3, the Universal rotary connector that extension rod is connected with ring.
4, the steel needle and needle folder of ring and bone section are connected and fixed.
Steel needle is generally fixed on the appropriate location near fracture by the process of operation, is pressed from both sides by needle and is fixed steel needle
The fixation and adjusting of bone are realized on Ilizarov external fixator or Taylor's skeleton.Ilizarov external fixator and Taylor's frame
Fixed fixture of threading a needle is all made of in certain hole location in upper and lower fixed ring, to reach the ring up and down of human fracture and external fixing rack
It is mutually permanently connected.But middle punch position and asymmetric is operated in actual operation, the hole location of conventional brace might not can be complete
Beauty matches position of threading a needle, furthermore, when steel needle is hammered into subjects bones by surgical, since the height of technical level is different, meeting
Occur steel needle the case where training off need to carry out it is secondary hammer into, will cause secondary or even multiple injury, so that operating difficulty is big, threshold
Height, and the error of very little will be brought great pain to patients.
Summary of the invention
It is an object of the invention to solve conventional brace can not perfect matching position of threading a needle cause surgical to follow closely steel needle
Be easy to appear when entering in subjects bones will appear the case where steel needle trains off need to carry out it is secondary hammer into, cause secondary or even multiple wound
Evil proposes a kind of nothing with guiding role to make the problem that operating difficulty is big, threshold is high, brings very big pain to patient
Grade adjusts fixture of threading a needle, and fine tuning may be implemented and fix, the accuracy and peace of the clinical reduction of the fracture not only can be improved in guiding of threading a needle
Quan Xing, and mitigate the operation strength of clinician, greatly improve the success rate of operation.
A kind of present invention folder through the following technical solutions to achieve the above objectives: step-less adjustment with guiding role is threaded a needle
Tool, including stepless regulator, steel needle guide locking device and fixture nut above and below steel needle, step-less adjustment fills the steel needle up and down
It sets including screw rod, upper fastening nut, lower fastening nut and sliding ring, the screw rod includes adjustable side and fixing end, and adjustable side is solid
Be scheduled on above fixing end, screw thread be covered on the adjustable side, on adjustable side 90 degree of interval open up there are two be parallel to screw rod axle center
The perforative straight-line groove of line, the sliding ring are sleeved on the adjustable side of screw rod, the internal screw thread of upper fastening nut and lower fastening nut
It is connect with being threadedly engaged on the adjustable side of screw rod, the upper and lower ends of sliding ring are fixed by upper fastening nut and lower fastening nut
In the middle part of the adjustable side of screw rod；The internal diameter of the sliding ring and the adjustable side clearance fit of screw rod offer bolt on sliding ring
90 degree of hole and sleeve connection hole through entire sliding ring, the bolt hole and sleeve connection interval are arranged；The steel needle guiding
Locking system includes steel needle sleeve and locking bolt, and one end of steel needle sleeve is provided with protrusion, and steel needle sleeve passes through on sliding ring
Sleeve connection hole and screw rod adjustable side on straight line slot, be provided with a locking hole on the side of steel needle sleeve, lock
Only bolt passes through the locking hole of bolt hole and steel needle cartridges sides on sliding ring, and steel needle is held out against in steel needle sleeve；It is described
The fixing end of screw rod is fixed on exterior I lizarov external fixator or Taylor's skeleton by fixture nut.
Further, the sleeve connection hole on the lateral surface and sliding ring of steel needle sleeve is interference fitted, outside steel needle sleeve
Straight line slot clearance fit on side and the adjustable side of screw rod.
Further, one end of the steel needle sleeve is provided with boss, and the outer diameter of boss is greater than the sleeve on sliding ring and connects
Connect the diameter in hole.
Further, the sliding ring realizes upper bottom by upper fastening nut and moving up and down for lower fastening nut
The step-less adjustment set.
Further, the width of the straight-line groove on the screw rod adjustable side is slightly larger than the outer diameter of steel needle sleeve.
Further, the screw thread matched with locking bolt is provided on the bolt hole on the sliding ring.
The beneficial effects of the present invention are: the present invention may be implemented fine tuning and fix, and provides guiding of threading a needle, not only can be improved
The accuracy and safety of the clinical reduction of the fracture, and mitigate the operation strength of clinician, greatly improve the success of operation
Rate.
