Description
Technical field
The present invention relates to medical instruments field, especially a kind of posterior cruciate ligament of knee ligament tibia locator.
Background technology
In daily life, ligament injury easily occurs in aggravating activities for ordinary people, and lives beyond joint rapidly making
When moving the action of range, posterior cruciate ligament of knee easily causes tearing or completely fracture due to passively pulling, and often with strain and bone
Folding, answers timely diagnoses and treatment and multiple connection after ligament injury.Posterior cruciate ligament of knee ligament tibia locator is posterior cruciate ligament of knee joint reparation
Indispensable surgical instrument in corrective surgery, existing posterior cruciate ligament of knee joint are repaired patient's generally use anterior approach mode and are determined
There is soft tissue obstruction in knee joint cavity room in position, sight is unclear, destroys blood transports equivalent risk, and such case needs patient in the process
With abundant clinical practice experience.Soft tissue obstruction in knee joint cavity room is reduced in order to reduce appearance in the course of surgery, is regarded
The problems such as line is unclear and the risk for destroying blood fortune, it is particularly necessary to develop new posterior cruciate ligament of knee ligament tibia locator.
Invention content
The object of the present invention is to provide a kind of posterior cruciate ligament of knee ligament tibia locators of simple operation, and inside enters after
The mode that road is placed carries out positioning and prosthesis, and reduction soft tissue in knee joint cavity room occurs and hinders, regards in the course of surgery
The problems such as line is unclear and the risk for destroying blood fortune, and without excision ligament stump, be conducive to Ligament healing and nervus vasculairs, increase
The strong possibility of successful surgery.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：
A kind of posterior cruciate ligament of knee ligament tibia locator, including caster assembly therefor, location hook, locking wheel, casing and locking mechanism, institute
It states and offers sliding slot on caster assembly therefor, the location hook is set in sliding slot, runs through offering threaded hole, the spiral shell in the sliding slot
It is threaded with locking wheel on pit, runs through on the caster assembly therefor and offers through-hole, casing, the set are equipped in the through-hole
It is fixed through locking mechanism between pipe and caster assembly therefor.
Posterior cruciate ligament of knee ligament tibia locator above-mentioned, the location hook include integrally formed sliding area and positioning area, institute
It states sliding area to be slidably connected in sliding slot, there is label on the sliding area.
Posterior cruciate ligament of knee ligament tibia locator above-mentioned, the locking mechanism include lock hole, limit scotch, spring and spiral shell
Mother, the lock hole are opened in caster assembly therefor side, and the lock hole is connected to through-hole, and the axis of the lock hole and through-hole hangs down
Directly and intersect, limit scotch, spring and nut, one end of the limit scotch and set have been sequentially arranged in the lock hole
Pipe contacts, and the nut is threadedly coupled with lock hole.
Posterior cruciate ligament of knee ligament tibia locator above-mentioned, the tail portion of the positioning area is integrally formed with locating cone, the positioning
Cone is cone, and the locating cone is vertically built in positioning area tail portion, and tip is towards caster assembly therefor, and the tail portion of the positioning area is also
Integrally formed with locating slot, the locating slot is circular groove, and the elongated central line of described sleeve pipe intersects with locating slot.
The tail portion of posterior cruciate ligament of knee ligament tibia locator above-mentioned, the positioning area is bent towards casing side, the positioning
The tail portion tip in area is overlapped integrally formed with locating cone, the elongated central line of described sleeve pipe with the axis of locating cone.
Posterior cruciate ligament of knee ligament tibia locator above-mentioned, the limit scotch offer and casing side close to one end of casing
The matched locking slot of face radian.
Posterior cruciate ligament of knee ligament tibia locator above-mentioned, described sleeve pipe upper end are additionally provided with anti-delinking part, are also opened up in described sleeve pipe
There are anti-skid chequer, described sleeve pipe lower end to be further opened with binding groove.
Posterior cruciate ligament of knee ligament tibia locator above-mentioned is further opened with open slot and portable slot on the caster assembly therefor, described
Through through-hole side is opened in, the portable slot is opened on caster assembly therefor open slot.
Posterior cruciate ligament of knee ligament tibia locator above-mentioned offers several lightening holes in the sliding slot.
Compared with prior art, the invention has the beneficial effects that：
1) a kind of posterior cruciate ligament of knee ligament tibia locator is positioned and is repaired hand by the way of the placement of rear medial approach
Art reduces the risk for occurring the problems such as soft tissue hinders, sight is unclear in knee joint cavity room in the course of surgery and destroying blood fortune,
And without excision ligament stump, is conducive to Ligament healing and nervus vasculairs, enhances the possibility of successful surgery；
2) by opening up sliding slot on caster assembly therefor, location hook is made to be slidably connected in sliding slot, to realize caster assembly therefor
It is relatively close and separate between location hook, it adjusts and positions into row distance with the posterior cruciate ligament of knee shin bone to different patients,
And caster assembly therefor is fixed also extremely convenient and stablizes by locking wheel, cooperation graduation mark is using can accurately control locator
The size of folding, to adapt to the positioning and clamping of different patients, and by open up multiple through-holes be used as lightening hole can
To mitigate the weight of locator so that patient's operation is more flexible light；
3) casing is fixed by using limit scotch, so that the distance between casing relative positioning hook energy
Enough adjustment, and limit scotch close to casing one end the setting at limit scotch of arc-shaped locking slot, casing to be arranged anti-
Sliding line each contributes to fixation of the limit scotch to casing；
4) since locking mechanism will be using will limit scotch and spring is set in the lock hole in ladder cellular type simultaneously
The structure screwed by nut, when nut push the spring pushes limit scotch to compress casing in turn, due to
The elastic force of spring-compressed persistently pushes limit scotch to compress casing, can prevent casing pine caused by nut loosening
It is de-, and lock hole is set as stepped hole, and the stroke of nut is limited, to prevent from screwing the too big stripped thread of dynamics and be made to casing
At damage, the spring travel is also limited, and to control compressed spring force, is avoided spring force and is made to casing greatly very much
At damage, it is too small and be not enough to compress casing to also avoid spring force；
5) a variety of patterns are arranged in the tail portion of locator, and to cope with the different situations of different patients, wherein locating cone contact is suffered from
The anti-skidding anticreep of energy behind person injury coordinates the binding groove of casing so that locator is more firm to the fixation of patient injury, and covers
The design form that the elongated central line of pipe is overlapped with the axis of locating cone, the elongated central line of casing and locating slot intersect all makes
Locator preferably positions patient injury；
6) by opening up open slot on caster assembly therefor, convenient for the installation of the components such as casing, by being opened on caster assembly therefor
If portable slot, convenient for locator carrying and take.
