Description
Technical field
This utility model relates to bone surgery technical field, especially relates to posterior cruciate ligament of knee joint reconstruction operations, is specially a kind of safety and makes the apparatus of posterior cruciate ligament tibial tunnel.
Background technology
When posterior cruciate ligament reconstruction art makes tibial tunnel, first have to squeeze into tunnel central guide pin, then utilize core drill to drill through sclerotin along guide pin and make tibial tunnel, by manual operations more than more than working, complete with " feel ", but owing to tibial tunnel internal orifice is positioned on rear side of knee joint, operation process still suffers from existing " accidentally dropping " causes guide pin to pierce deeply, core drill pierced deeply or guide pin moves with core drill, causes the possibility that nest neural blood vessel damages.Although having clinically by measuring length of tunnel, installing at guide pin and core drill surface and limit the method for deep module to avoid piercing deeply, but its method being loaded down with trivial details, time-consuming, poor accuracy, also cannot limit guide pin with boring core drill reach.Therefore, it is proposed that a kind of method making posterior cruciate ligament tibial tunnel and apparatus, with minimizing, operator is avoided " accidentally dropping " or guide pin move with core drill and cause blood vesssls and nerves injuries, to make posterior cruciate ligament tibial tunnel safely and fast.
Utility model content
The purpose of this utility model is in that the apparatus providing a kind of safety to make posterior cruciate ligament tibial tunnel, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme: a kind of safety makes the apparatus of posterior cruciate ligament tibial tunnel, pierce device including guide pin, guide pin, core drill, core drill pierce device, orthopaedic drill, and its surface being mainly characterized by guide pin is provided with guide pin and pierces labelling and core drill pierces labelling, guide pin pierces device and is provided with that guide pin limits deep sleeve, core drill bare terminal end to be provided with drill jig clipped labels, core drill pierces device and is provided with guide pin holder and deep sleeve limit by core drill.
Guide pin pierces labelling and core drill pierces labelling, both are positioned at the fixed position of guide pin, wherein guide pin pierces the labelling air line distance from guide pin top is that locating tip arrives the air line distance stopping hole, when piercing guide pin, no matter the length in tunnel is how many, drill jig is all held on herein, and core drill pierces the labelling air line distance from the guide pin top air line distance equal to core drill clipped labels to core drill top.This labelling is it is meant that core drill moves along guide pin, and core drill nose motion is to guide pin tip, and drill jig is synchronized with the movement herein.Preferably, this is labeled as annular, wide 1mm, laser marking machine scribe and form.
Preferably, described guide pin pierces device and includes tunnel central guide pin localizer, the guide pin deep sleeve of limit, guide pin limits deep sleeve set on the surface of guide pin positioning wrap cylinder, both are fixed by the first fastening screw of guide pin depth stop, guide pin limits deep sleeve, guide pin positioning wrap cylinder and guide pin positioning inner sleeve cylinder three coaxial, and axial line passes through locating tip.Guide pin is limit deep sleeve set behind the surface of guide pin positioning wrap cylinder, the distance that the deep sleeve of limit is set to locating tip is made to fix, it is consistent that this numerical value pierces mark depths with the guide pin of the guide pin on guide pin surface, that is pierce mark when drill jig is fixed to guide pin, when the deep matter of guide pin pointed drill touches locating tip, drill jig also touches guide pin and limits deep sleeve pipe, makes electric drill be stopped, reaches to limit deep purpose.The length of tibial tunnel only affects location guide pin inner sleeve seesawing in the guide pin outer sleeve of location, and the internal diameter of the guide pin deep sleeve of limit is bigger, it is allowed to the tail end of location guide pin inner sleeve is at internal motion.Therefore apply this device and proceed to guide pin, the tunnel degree of depth mustn't be paid close attention to again.
Preferably, described guide pin limits deep sleeve to be tubular, interior warp is more than guide pin positioning wrap cylinder, one end is completely unlimited, and the other end is closed, and the stop hole of a circle is opened in centre, stop bore dia can hold guide pin by, limit drill jig pass through, the surface of the nearly opening end of guide pin depth stop offers through hole, is inside provided with the first fastening screw, tightens this screw and guide pin depth stop can be fixed to tunnel central guide pin locator surfaces.
Preferably, described core drill pierces device and includes guide pin holder and core drill and limit deep sleeve.Core drill limits the outer surface of deep sleeve to be set with guide pin holder, and both are coaxial, and inner containment core drill passes through along guide pin.Both can relative sliding, and can pass through second fastening screw fix.Guide pin holder and core drill are limit deep sleeve to pass through simple connection to combine one by this device, play guide pin simultaneously and fix and the core drill deep function of limit.Its principle is, but core drill top along guide pin move to guide pin point time, tunnel is drilled through.Therefore after correctly piercing guide pin, connecting guide pin holder, slip core drill depth stop makes its outside opening be positioned at core drill and pierces mark, will screw the second fixed screw.When core drill drills through osseous tunnel, drill jig also receives stop, it is prevented that core drill pierced deep.
Preferably, described guide pin holder includes core drill sleeve, the second fastening screw, can fix groove, the 3rd fastening screw and connect support, and core drill sleeve is connected by connection support with fixing groove, and both are positioned on same axis.Guide pin is set with core drill sleeve, core drill, electric drill successively, can fix groove after squeezing into, after tibia sclerotin is close to by core drill sleeve, fastens screw by the 3rd and be fixed on by guide pin and can fix in groove.Its objective is to be limited by guide pin by outside support, it is prevented that owing to the excessive guide pin of frictional force moves forward with core drill.
Preferably, described core drill sleeve fastens screw with second, and the opening of one end is inclined-plane.Owing to tunnel is that its opening is that inclined-plane can make guide pin holder be close to tibia sclerotin to the oblique passage on rear by front lower.Inclined-plane and guide pin holder major axis be 50 degree comparatively suitable.
Preferably, described groove of fixing is lateral opening, and bottom offers through hole, is interspersed with the 3rd fastening screw in this through hole.Side opening is easy to preventing of guide pin.
Preferably, described core drill limits deep sleeve diameter less than drill jig diameter, more than core drill diameter, in order to it stops electric drill, is easy to core drill and passes freely through.One end edge diameter increases, and external diameter is equal to core drill sleeve diameter, can prevent core drill from limitting deep sleeve whole slide in core drill sleeve.
Compared with prior art, the beneficial effects of the utility model are:
The method and apparatus that application this utility model is mentioned, it is possible to be prevented effectively from the making posterior cruciate ligament tibial tunnel of injured nerve blood vessel, safety.
This apparatus is easy to assembly, and operational approach is simple, and in art, orthopedist does not need to measure and calculate the tibial tunnel degree of depth, just can accurately make tibial tunnel, shorten operating time, improves work efficiency.
Application process and apparatus, do not need too much to operate with feel, and the experience dependency of doctor is little, makes the program standardization of making posterior cruciate ligament tibial tunnel, reduces operating difficulty, shortens the learning curve of low age and service seniority orthopedist.
