Abstract
The utility model discloses a poking and hinging device of a minimally-invasive poking plastic internal fixing device. The poking and hinging device 1 is internally provided with a stepped hole A11, a hole B12 and a screw hole 13, and the longitudinal cross section of the poking and hinging device 1 is in a pentagon shape which is formed by cutting one corner from a rectangular shape, i.e. the lower end of the poking and hinging device 1 is a sharp corner 14 with an inclined surface. When the poking and hinging device disclosed by the utility model is in use, the minimally-invasive poking plastic internal fixing device is assembled by arranging a fixing bar and a vertebral pedicle locking screw rod of the minimally-invasive poking plastic internal fixing device on the poking and hinging device, the defects that a wound is long, more blood loss is caused, the infection is easily caused, the external beauty of a patient can be affected, and the like due to a conventional open operation treatment method at present can be overcome, and compared with the prior art, the poking and hinging device has the advantages that the application range is wide, the operation is simple and convenient, the structure is stable and reliable in a using process, the anti-rotation effect is stronger, and the like.
Description
Technical field
This utility model relates to a kind of orthopedic operating apparatus, particularly a kind of for correcting Wicresoft's sled group shaping inner fixer sled group hinge means of spinal defect.
Background technology
Both at home and abroad for the patient of idiopathic scoliosis, adopt conventional therapy to carry out orthopedic internal fixation treatment at present more.This Therapeutic Method wound is long, hemorrhage many, easily infects, and particularly affects patient's external beauty treatment and is difficult to be accepted by patient.Along with the high-precision technology of medical apparatus and instruments, the development of electronic digital imaging technique, and vertebral column minimally invasive orthopedic surgical technique is also rapidly developed, realize the orthopedic internal fixation treatment of minimally invasive spine surgical, the orthopedic Internal Fixation of this Minimally Invasive Surgery is because wound is little, go out insufficiency of blood, not easy infection, do not affect patient's beauty treatment and accepted extensively by patient, overcome to a certain extent the deficiency of conventional therapy, pedicle screw as a kind of in the minimally invasive spine surgical internal fixation device of being invented by No.2 Hospital Attached to No.3 Military Medical College, PLA and a kind of spinal column percutaneous internal fixation system (CN201210395392.7), it is only adapted to Wicresoft's internal fixation treatment of fixing in lumbar vertebra compression fracture micro-wound orthopedic and some breast lumbar vertebra sexually transmitted disease (STD)s, the scope of application is narrow, cannot carry out micro-wound orthopedic internal fixation treatment for idiopathic scoliosis disease, and poor stability (its adopt be that two dimension is fixing).
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide, one is applied widely, easy and simple to handle, in use Stability Analysis of Structures is reliable, and Wicresoft's sled with certain anti-rotate effect is dialled shaping inner fixer sled group hinge means.
The technical solution of the utility model is: a kind of Wicresoft sled is dialled shaping inner fixer sled and dialled hinge means, sled is dialled in hinge means and is provided with shoulder hole A, hole B and screw hole, the longitudinal section of sled group hinge means is shaped as rectangle and cuts away the pentagon at an angle below, and the lower end of sled group hinge means is a wedge angle with inclined-plane.
Hold-down bars and the pedicle of vertebral arch lock nut of when use, Wicresoft's sled being dialled to shaping inner fixer are arranged on this utility model, be assembled into Wicresoft's sled and dial shaping inner fixer, the wound that can overcome present conventional therapy Therapeutic Method existence is long, hemorrhage many, easily infect, affect patient's the weak point such as external beauty treatment, compared with prior art, have applied widely, easy and simple to handle, in use Stability Analysis of Structures is reliable, has the advantages such as stronger anti-rotate effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the right view of Fig. 2;
Fig. 4 is this utility model using state schematic diagram.
The specific embodiment
Below in conjunction with figure and embodiment, detailed construction of the present utility model is further described.
As Figure 1-3: a kind of Wicresoft sled is dialled shaping inner fixer sled and dialled hinge means, sled is dialled in hinge means 1 and is provided with shoulder hole A11, hole B12 and screw hole 13, the longitudinal section of sled group hinge means 1 is shaped as rectangle and cuts away the pentagon at an angle below, and the lower end of sled group hinge means 1 is a wedge angle 14 with inclined-plane.
When use, the hold-down bars 2 of Wicresoft's sled being dialled to shaping inner fixer is arranged in this utility model shoulder hole A11, and fixing by adjustment screw 4, pedicle of vertebral arch sled is dialled to screw rod 3 and be arranged on this utility model hole B12, and pedicle of vertebral arch sled is dialled screw rod 3 vertical with hold-down bars 2 (as shown in Figure 4), this utility model adjustment screw 4 has sled and dials fixing function in orthopedic and elastic pressurized, regulate described adjustment screw 4 can make hold-down bars 2 swing in shoulder hole A11, and then drive pedicle of vertebral arch sled group screw rod 3 to swing, easy to adjust reliable.
