Abstract
This utility model relates to a kind of micro-wound percutaneous spinal column dilator, and comprise distraction forcep main body and strut blade, its main body comprises the distraction forcep in 6 joints, can increase the arm of force strutted, and rear is provided with and is in clamping connection bar; Strut blade to be connected with body normal, blade is half arc, and remote design becomes semicircular breach, can percutaneous insert between pedicle screw pitman on strut.This utility model simplicity of design, application is convenient, and it is large to strut the arm of force, and rear is in clamping connection bar, can percutaneous distraction pedicle screw, and the operation in favourable Rhizoma Atractylodis Macrocephalae, application safety, should be widely promoted application.
Description
Technical field
The present invention relates to a kind of micro-wound percutaneous spinal column dilator, belong to medical instruments field.
Background technology
Along with the development of vertebral column minimally invasive technology, the application of percutaneous cervical arc root screw technology is more extensive, and for the patient of lumbar vertebra compression fracture, percutaneous puts the wound that nail can reduce operation.But, often more difficult for the distraction reduction of fracture, body surface to strut limited strength, reset effect not good, need simpler, the effective instrument of one, pedicle of vertebral arch strutted, thus reach pyramidal support, make the object of the reduction of the fracture.
Summary of the invention
The purpose of this utility model is to provide a kind of micro-wound percutaneous spinal column dilator, and strut problem with what solve micro-wound percutaneous pedicle screw, it can strut screw by the mini-incision through putting nail, and soft tissue injury is little.
The micro-wound percutaneous versus posterior vertebral dilator that the utility model proposes, comprise distraction forcep main body 1 and strut blade 3, distraction forcep main body 1 comprises binding clip and hands handle, the binding clip place of distraction forcep main body 1 is connected with joint connector 4, distraction forcep main body 1 and joint connector 4 are positioned at same plane, described joint connector 4 is 6 articulation structures, two, its top joint is respectively equipped with and struts blade 3, the described blade 3 that struts is arranged vertically with described distraction forcep main body 1, strut blade 3 in half arcuate structure, described two actuated position strutting blade 3 are positioned opposite, its far-end is provided with semicircular indentations, the handle place of described distraction forcep main body 1 is provided with and is in clamping connection bar 2.
In this utility model, described in strut blade and be connected with distraction forcep body normal, strutting blade is half arc, and remote design becomes semicircular breach, can percutaneous insert between pedicle screw pitman on strut.This structural design is simple, and application is convenient, and it is large to strut the arm of force, and rear is in clamping connection bar, can percutaneous distraction pedicle screw, the operation in favourable Rhizoma Atractylodis Macrocephalae.
This utility model adopts the joint connector of 6 articulation structures, the arm of force strutted can be increased, easy to operate, strut blade and distraction forcep body normal is connected, can make to strut blade and vertically insert mini-incision, the arc notch of far-end can effectively contact with pitman, convenient strutting screw, being in clamping connection bar and effectively maintaining and strut distance of main body rear, simple to operate, practical.
The effect that this utility model is useful is: this utility model structure is simple, reasonable in design, can strut pedicle of lumbar vertebral arch screw through the otch percutaneous of lumbar vertebra Wicresoft, be convenient to the operation of operator, reduce soft tissue injury, the problem of effective solution percutaneous cervical arc root screw fracture distraction reduction, has saved operating time.This infrastructure cost is low, simple to operate, definite effect, can wide popularization and application.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is for strutting blade 3 structural representation.
Number in the figure: 1 is distraction forcep main body, and 2 for being in clamping connection bar, and 3 for strutting blade, and 4 is joint connector.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to shown in accompanying drawing 1-2: this minimal invasion pedicle screw distraction forcep, comprise distraction forcep main body 1, wherein distraction forcep main body 1 comprises binding clip and handle, distraction forcep main body 1 clamp headend be provided with joint connector 4; The handle rear end of distraction forcep main body 1 is provided with and is in clamping connection bar 2, and what distraction forcep main body 1 front end was provided with two arcs struts blade 3, struts that blade 3 is vertical with distraction forcep main body 1 to be connected, and struts the curved breach of blade 3 far-end.
To strut blade 3 percutaneous inserts between pedicle screw, the arc notch strutting blade 3 is stuck on pedicle screw pitman, the handle of pressurizing and propping clamp main body 1, make to strut blade 3 distraction pedicle screw by the joint connector of 6 articulation structures of distraction forcep main body 1, be in clamping connection bar 2 to clamp, complete strutting pedicle screw.This utility model structure is simple, easily operates, Wicresoft can carry out strutting of pedicle screw, little to muscle tissue damage, struts effective, is worthy of popularization.
Although this utility model illustrates by reference to preferred enforcement and describes, those skilled in the art should understand, and in the scope of claims, can do the various change in form and details.
