Abstract
The utility model relates to a wing type inner fixing device in lumbar isthmus. The device belongs to the field of medical instruments and is applied to an operation of lumbar spondylolysis. The wing type inner fixing device in the lumbar isthmus is composed of a wing (1) and a fixing device body (2) and is characterized in that the wing (1) is in an arc sheet shape, the fixing device body (2) is in a U-shaped structure, an appropriate inner fixing device is selected to implement the operation according to diagnosis, depth and directions of the operation is first determined, the inner fixing device is planted into an operation opening to be fixed at a position required by the operation, and an operation aim is achieved.
Description
Technical field
This utility model relates to a kind of airfoil type lumbar isthmus inner fixer, belongs to medical instruments field, is applicable in the spondylolysis and spondylolithesis of the lumbar spine operation.
Background technology
Spondylolysis and spondylolithesis of the lumbar spine is that the isthmus bony defect between the inferior articular process is discontinuous on the vertebral arch of lumbar vertebra one or both sides, also claims spondylolysis or isthmus not to connect.
Spondylolysis and spondylolithesis of the lumbar spine is the commonly encountered diseases therefore that causes low back pain, also is the major reason that causes lumbar spondylolisthesis, and its basic lesion is the fracture of isthmus bone, and to the forfeiture of the little joint antagonism of vertebral body shear stress ability, the lumbar vertebra unstability finally causes forward slippage of vertebral body.Its cardinal symptom is lumbago and skelalgia, and painful area and character are had nothing in common with each other, and can be persistence or intermittence, and only pain person when overworked is also arranged, and pain can be confined to lumbosacral region, also can be to hip, and sacrococcygeal region or lower limb radiation.
The drug treatment that isthmus splits not yet is promoted at present, and the Therapeutic Method of clinical general employing has: the same prolapse of lumbar intervertebral disc of (1) non-operative treatment; (2) slippage degree severe patient and cauda equina nerve root pressure symptom non-operative treatment appears and can not alleviation person, feasible operative treatment, operation interior fix etc. that comprise decompression, merge and reset.
Along with the increasingly mature of technique for fixing in the pedicle nail and the plurality of advantages that provides is be provided, the operative treatment spondylolysis and spondylolithesis of the lumbar spine becomes the primary treatment method gradually, but simultaneously consequently also increasing with the operation related complications, modus operandi that should How to choose the best in clinical is to obtain best surgical effect.
Summary of the invention
This utility model provides a kind of airfoil type lumbar isthmus inner fixer with the characteristics such as simple in structure, easy to operate.
The technical solution of the utility model is as follows:
Airfoil type lumbar isthmus inner fixer is characterized in that by wing (1), fixedly body (2) forms: the curved lamellar of wing (1), and head is hook-shaped; Fixedly body (2) is U-shaped structure, both sides arc step, and the step middle part is hollow structure.
The curved lamellar of wing (1) is utilized the tension band principle, makes isthmus reach fixing in the elasticity, can the Isthmic bone grafting direct weighting be conducive to isthmus and split bony union with fashion, is used for the treatment of spondylolysis and spondylolithesis of the lumbar spine.
Fixedly the design of the U-shaped and step of body (2) has elasticity, can prevent to close on the effect of the regression of intervertebral disc.
By imaging examination before the art, the diagnosis patient diseases such as row x-ray, CT examination, determine patient's surgery location, type of surgery and implement internal fixation operation, select suitable inner fixer according to diagnosis, implement operation: at first determine the degree of depth and the orientation of operation, the row operation opening is implanted inner fixer, be fixed to the requirements of operation position, realize the operation purpose.
Airfoil type lumbar isthmus inner fixer of the present utility model intends adopting up and down between two spinous process and 3 of both sides superior articular process's basilar part, transverse process basilar part and pedicle of vertebral arch three junctions as interior fixed pivot, can not affect the processing of complication, simultaneously to split direction almost vertical for the cohesion that produces of holder and isthmus, meet interior fixedly requirement, in addition, distinctive design can make holder laterally pressurize, and the assurance fixation hook can not come off and break transverse process.
Airfoil type lumbar isthmus inner fixer has advantage simple in structure, easy to operate, that operation wound is little, safe and reliable, but fixing in its few intercurrent disease and the elasticity, meets spondylolysis and spondylolithesis of the lumbar spine anatomy and biomechanical characterization, is suitable for Orthopedic Clinical and applies.
Description of drawings
Figure is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Airfoil type lumbar isthmus inner fixer is characterized in that by wing (1), fixedly body (2) forms: the curved lamellar of wing (1), and head is hook-shaped; Fixedly body (2) is U-shaped structure, both sides arc step, and the step middle part is hollow structure, select suitable inner fixer according to diagnosis, implement operation: at first determine the degree of depth and the orientation of operation, the row operation opening, implant inner fixer, be fixed to the requirements of operation position, realize the operation purpose.
Claims (1)
1. airfoil type lumbar isthmus inner fixer is characterized in that by wing (1), fixedly body (2) forms: the curved lamellar of wing (1), and head is hook-shaped; Fixedly body (2) is U-shaped structure, both sides arc step, and the step middle part is hollow structure.
