Description
Technical field
The utility model discloses a kind of preceding tibial avulsion fracture of posterior cruciate ligament fixed guider, under arthroscope
Bone block is maintained to reset in the art of preceding tibial avulsion fracture of posterior cruciate ligament treatment, accurate tunnel preparation guiding, fracture fixation,
It is related to technical field of surgical instruments.
Background technique
For the patient of preceding tibial avulsion fracture of posterior cruciate ligament, assist maintaining bone block multiple in arthroscopic surgical procedures
Position is stablized, the preparation of accurate tunnel is oriented to, fracture fixation, is being guaranteed that bone block is maintained to reset simultaneously, is not being interfered in tunnel preparation process
Pilot pin and 4.0mm core drill are smoothly pierced by sclerotin, and subsequent draught line importing process tunnel between proximal tibia and sclerite
Road point-blank, prevents from maintaining bone block to reset bone block in difficult and tunnel preparation process usually using cruciate ligament locator
Displacement and subsequent conducting wire introduce difficult good bit after more conducively bone block being maintained to reset compared with single-point stress by two points stress
It sets, dispersive stress is conducive to reduce the iatrogenic fragmentation of sclerite in actual mechanical process, guarantees the success rate of operation, when shortening operation
Between, it is significant to mitigate postoperative complications.
It well resets and maintains after resetting currently, routine clinical surgical instrument cannot achieve auxiliary arthroscope progress bone block
Position, precise positioning and maintenance difficulty are big when prepared by osseous tunnel, it is desirable that and do not interfere pilot pin, 5.0mm core drill to be pierced by sclerite,
While the implantation of draught line is not interfered in osseous tunnel direction unanimously at maintenance 2.Therefore, it researches and develops one kind and has both the reset of maintenance bone block, essence
Certainly position, while not interfering osseous tunnel to prepare, the operation suitable for preceding tibial avulsion fracture of posterior cruciate ligament minimally-invasive treatment
Instrument improves success rate of operation to shorten operating time, early postoperation functional training, adapts at present precisely medical operating, quickly
There is very big market value in the theory of rehabilitation and direction.
Summary of the invention
The purpose of this utility model is to provide a kind of preceding tibial avulsion fracture of posterior cruciate ligament of fast accurate to control
Guider is treated, minimal invasive operation under arthroscope has both and maintains bone block reset, precise positioning under mirror, while not interfering osseous tunnel
Preparation, improves the success rate of operation, shortens operating time, it is postoperative can early functional exercise, accelerate rehabilitation.
A kind of preceding tibial avulsion fracture of posterior cruciate ligament fixed guider described in the utility model, feature exist
In: it is made of curved frame, leading arm and disassembled casing etc.；
Wherein, the middle part of curved frame be equipped with angle indicator scale, 0 ° ~ 75 ° of angular range；Leading arm by bolt with
Hinge connection in the middle part of curved frame can arcuately locating support be slided；The end of leading arm, which is equipped with, resets locator, and it is fixed to reset
Position device is arch, the center of circle that two tip lines of arch pass through circle where main body arc locating rack；
Curved frame bottom is additionally provided with casing and consolidates cylinder, and casing consolidates in cylinder and is fitted with disassembled casing；It is removable to overcome difficulties
It is carved with scale on pipe tube body, tape measure marrow road length can be passed through.
Tibial avulsion fracture of posterior cruciate ligament Minimally Invasive Surgery before the utility model is suitble to.
The utility model has the following positive effects: leading arm is fixed on main body curved frame by fixing bolt, pass through
Angle indicator scale selects appropriate angle to fix；Two point precisely resets locator and is conducive to that bone block is maintained to reset, while not interfering and determining
Position needle, core drill are pierced by sclerotin, and then in draught line importing process between proximal tibia and sclerite tunnel in straight line
On, it prevents that bone block is maintained to reset bone block displacement in difficult and tunnel preparation process and subsequent lead usually using fork ligament locator
Line introduces difficult；Two point precisely resets good after locator more conducively maintains bone block to reset by two points stress compared with single-point stress
Position, dispersive stress are conducive to reduce the iatrogenic fragmentation of sclerite in actual mechanical process, guarantee the success rate of operation, shorten operation
Time, it is significant to mitigate postoperative complications.Disassembled casing above has scale that can measure osseous tunnel length as needed, interior
Diameter can accommodate 2.0mn Kirschner wire and facilitate positioning.The utility model is applied under arthroscope in minimal invasive operation, has both and ties up under mirror
Bone block reset, precise positioning are held, while not interfering osseous tunnel to prepare, improves the success rate of operation, shortens operating time, postoperative energy
Enough early functional exercises accelerate rehabilitation.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is that the utility model resets locator structure schematic diagram；
Wherein: 1, arc locating support；2, angle indicator scale；3, bolt；4, leading arm；5, locator is resetted；6, it covers
Manage firm cylinder；7, disassembled casing.
Specific embodiment
The following further describes the utility model with specific embodiments.
As shown in Figure 1, preceding tibial insertion of posterior cruciate ligament fracture guider described in the utility model is by main body fixed frame
1, leading arm 4 and disassembled casing 7 etc. form；
Wherein, the middle part of curved frame 1 be equipped with angle indicator scale 2,0 ° ~ 75 ° of angular range；Leading arm 4 passes through spiral shell
Bolt 3 is connect with 1 middle part hinge of curved frame, is located at 2 position of angle indicator scale, can arcuately locating support 1 be slided, be passed through
Fixed angle indicator scale 2 selects appropriate angle to fix, it is ensured that the vertical fracture line of sclerite is fixed.
The end of leading arm 4, which is equipped with, resets locator 5, and resets locator 5 is arch (reference Fig. 2 shown in), and the two of arch
Tip (two point is accurate) line passes through the center of circle of circle where main body arc locating rack 1, resets locator and passes through two tip (two points
Precisely) bone block is maintained to reset, gap is more than or equal to 5.0mm, and pilot pin and 5.0mm core drill is not interfered to be pierced by sclerotin.
1 bottom of curved frame is additionally provided with casing and consolidates cylinder 6, and is located on concentric radius of circle extended line；Disassembled casing 7
It consolidates cylinder 6 by casing to connect with curved frame 1, Intraoperative position Kirschner wire is by disassembled casing 7, from the double of leading arm 4
Two tip line midpoints that point precisely resets locator 5 pass through, and reach precise positioning purpose.On disassembled casing pipe 7
It is carved with scale, 2.0mn Kirschner wire can be accommodated by tape measure marrow road length, internal diameter, reach precise positioning purpose.
