Description
Technical field
This utility model belongs to operation device field, relates in particular to and under a kind of total joint mirror, treats ligamentum intraarticulare stop avulsion fracture device.
Background technology
In knee joint, there are two ligamentaum cruciatums.Anterior cruciate ligament is attached to tibia area intercondylaris anterior, and oblique rear outer top terminates in the rear part of condylus lateralis femoris inner face, has the effect of preventing tibia reach.Posterior cruciate ligament is positioned at the rear inner side of anterior cruciate ligament, short compared with anterior cruciate ligament, rises from the rear end of tibia area intercondylaris posterior and lateral meniscus, and oblique front upper interior side, invests front part of condylus medialis femoris outside, has the effect moving after restriction tibia.
Posterior cruciate ligament reconstruction difficult point is because tibial insertion of posterior cruciate ligament is positioned at 15mm left and right, tibial plateau below, do not reach dead-centre position, reached dead-centre position but in above-mentioned structure arthroscope anterior lateral cervical approach cannot see tibial insertion of posterior cruciate ligament, knee joint rear is covered with important blood vessels nerve, as damage can cause causing lower limb disorder, be difficult to guiding steel wire to pass from tibia rear, be also difficult to reach Anatomical Reconstruction location.
Utility model content
The purpose of this utility model is to provide under a kind of total joint mirror treats ligamentum intraarticulare stop avulsion fracture device, is intended to solve the deficiency in above-mentioned background technology.
This utility model is achieved in that and comprises soft conduit, seal wire, guide rod and expansion skin device; Described expansion skin device is plastic conduit, one end opening is greater than other end opening, and described expansion skin device both ends open is all greater than conduit diameter, wherein, described guide rod one end is provided with axle center perpendicular to the through hole of the guide rod body of rod, the aperture of described through hole is not less than the diameter of conduit, and described conduit is built-in with mobilizable seal wire, and described guidewire length is greater than conduit; Described conduit is built-in and expansion Pi Qizhong in movable mode, and described catheter length is greater than expansion skin device length.
Preferably, to expose to conduit one end be that elasticity is hook-shaped to described seal wire.
Preferably, described guide rod is the end that holds that is provided with rubbing surface away from through hole one end.
Preferably, described guide rod is provided with scale.
Preferably, described conduit is provided with scale.
Shortcoming and defect than prior art, the utlity model has following beneficial effect: this utility model is simple in structure, design ingenious, can apply with total joint mirror under treat ligamentum intraarticulare stop avulsion hands art, because whole operative process is all to have operated by outer cannula, can effectively avoid in conventional operative process, easily occur that damage knee joint rear important blood vessels is neural, cause causing the problem of lower limb disorder, and, this utility model can be able to pass guiding steel wire very easily from tibia rear, and reach Anatomical Reconstruction location.
Accompanying drawing explanation
Fig. 1 treats conduit in ligamentum intraarticulare stop avulsion fracture device, seal wire and expands the structural representation under skin device assembled state under total joint mirror;
Fig. 2 is the structural representation for the treatment of guide rod in ligamentum intraarticulare stop avulsion fracture device under total joint mirror.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, and be not used in restriction this utility model.
As shown in Fig. 1～2, wherein, Fig. 1 treats conduit in ligamentum intraarticulare stop avulsion fracture device, seal wire and expands the structural representation under skin device assembled state under total joint mirror; Fig. 2 is the structural representation for the treatment of guide rod in ligamentum intraarticulare stop avulsion fracture device under total joint mirror.
Under total joint mirror, treat a ligamentum intraarticulare stop avulsion fracture device, comprise soft conduit 1, seal wire 2, guide rod 3 and expansion skin device 4; Described expansion skin device 4 is plastic conduit, one end opening is greater than other end opening, and described expansion skin device 4 both ends opens are all greater than conduit 1 diameter, wherein, described guide rod 3 one end are provided with axle center perpendicular to the through hole 5 of guide rod 3 bodies of rod, the aperture of described through hole 5 is not less than the diameter of conduit 1, and described conduit 1 is built-in with mobilizable seal wire 2, and described seal wire 2 length are greater than conduit 1; Described conduit 1 with movable mode built-in with expand in skin device 4, and described conduit 1 length is greater than and expands skin device 4 length.
In this utility model embodiment, more specifically, described guide rod 3 is to be provided with holding of rubbing surface to hold 5 away from through hole one end.Described guide rod is provided with scale.Described conduit is provided with scale.
In actual application of the present utility model, rear cross reconstruction guider inserts through the interior below of PCL from front medial approach, inner underside in sclerite under Arthroscopy pierces diameter 2.0mm bone hole, by rear intersection sight, from front lateral approach, through the outer lower side of PCL, inserting, outside lower sidetracking in sclerite under Arthroscopy enters 2.0mm bone hole, guide rod 3 is inserted between two borings, by two, expanding skin device 4 (diameter is insertion end compared with small end) is inserted into respectively in two bone hole side otch skin histologies, and the pipeline opening that expands skin device 4 is all aimed at bone hole, then conduit 1 being inserted to a side expands in skin device 4, conduit 1 enters in bone hole the through hole 4 from guide rod 3 again and passes, guide rod 3 is moved to inner underside hole and through hole 4 is alignd with inner underside hole, conduit 1 is expanded in skin device 4 and extend out to lower limb outside to another side from inner underside hole, seal wire 2 is inserted in conduit 1, seal wire 2 is connected with the steel wire that is connected with prosthetic ligament tissue away from insertion end, seal wire 2 is stretched out from conduit 1 other end, then conduit 1 is extracted from inner underside nose end, and extract guide rod 3.Under seal wire 2 tractions and Arthroscopy, prosthetic ligament tissue is placed in to precalculated position, prosthetic ligament organizes two ends steel wire to be arranged in respectively both sides expansion skin device 4, two ends steel wire is connected respectively to the stop may be stuck in outside bone hole, make two ends steel wire be separately fixed at outside, two bone holes, extract both sides and expand skin device 4, sew up the incision, complete operation.
In this utility model, because whole operative process is all to have operated by outer cannula, can effectively avoid in conventional operative process, easily occur that damage knee joint rear important blood vessels is neural, cause causing the problem of lower limb disorder, and this utility model can be able to pass guiding steel wire very easily from tibia rear, and reach Anatomical Reconstruction location.
In this utility model embodiment, more specifically, for avoiding seal wire 2 to be easier to be connected with steel wire, and in the problem without easily extracting from conduit 1 under mode of operation, it is that elasticity is hook-shaped that described seal wire 2 exposes to conduit one end.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
