Abstract
This utility model relates to a kind of rib semi-surrounding compression fixator; Scheme is, comprise two U-board and two screws, be connected with the connecting plate paralleled with U-board upper plate between the upper plate of two U-board, the upper plate of U-board has can through the through hole of screw, the lower plate of U-board offers the screwed hole corresponding with through hole, and screwed hole matches with screw; This utility model can reduce intercostal nerves blood vessel injury, reduces osseous tissue damage, the fixing pressurization of upper and lower plates, fixation, reduces hold-down screw and to get loose probability.
Description
Technical field
This utility model relates to medical apparatus, particularly a kind of easy and simple to handle, use safety, wound are little, therapeutic effect is good rib semi-surrounding compression fixator.
Background technology
Fracture of rib injured by road traffic accident, exceed in the caused thoracic trauma such as Falling Injury very common.Along with the progress of the vehicles and increasing further of Architectural Equipment, many, multistage fracture of rib is in significantly increasing trend.And the thoracic wall therefore caused is unstable, flail chest causes breathing, circulatory function obstacle, clinical treatment is more difficult, and mortality rate is higher.The treatment principle of fracture of rib is analgesia, fixes thorax, recovers the stability of thorax and prevent and treat complication etc.In the treatment of multiple multistage fracture of rib, surgical menopause has more and more become everybody common recognition, and application is at present NiTi memory alloy embracing plate, Absorbable rod rib nail, multi-claw blade plate more widely.
1, Ultimum Ti is embraced ring device and has been widely used in clinical at present, but due to its price costly, be difficult to promote at basic hospital, and its circumferential type structure is avoiding there is certain defect in intercostal nerves, blood vessel constriction, damaged.
2, Absorbable rod rib nail due to rib thickness less, in art, action need is too much peeled off periosteum and easily occurs in drill process that secondary is fractured, therefore needs other internal fixtion such as auxiliary steel wire, Kirschner wire more, is difficult to be applied to separately clinical.
3, multi-claw blade plate is avoiding there is certain defect in intercostal nerves, blood vessel constriction, damaged on the one hand, and on the other hand because rib thickness is less, internal fixation screw is difficult to effectively be combined with rib, and fixation degree is low.
Utility model content
For above-mentioned situation, for overcoming the defect of prior art, the object of this utility model is just to provide a kind of rib semi-surrounding compression fixator.
The technical solution of the utility model is, comprise two U-board and two screws, the connecting plate paralleled with U-board upper plate is connected with between the upper plate of two U-board, the upper plate of U-board has can through the through hole of screw, the lower plate of U-board offers the screwed hole corresponding with through hole, and screwed hole matches with screw.
This utility model can reduce intercostal nerves blood vessel injury, reduces osseous tissue damage, the fixing pressurization of upper and lower plates, fixation, reduces hold-down screw and to get loose probability.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
As shown in Figures 1 to 9, this utility model comprises two U-board 1 and two screws 2, the connecting plate 3 paralleled with upper plate 101 is connected with between the upper plate 101 of two U-board 1, the upper plate 101 of U-board 1 has can through the through hole 4 of screw 2, the lower plate 102 of U-board 1 offers the screwed hole 5 corresponding with through hole 4, and screwed hole 5 matches with screw 2.
The upper plate 101 of described U-board 1 and lower plate 102 can be close to each other when applying power in opposite directions, and it has certain elasticity.
Described U-board 1 and connecting plate 3 are in integrative-structure.
Described U-board 1 and connecting plate 3 are made by metal material.U-board 1 can design different radian according to human body ribbed shape, also can carry out artificial bending as required moulding in operation application process.
Described through hole 4 is positive bellmouth, and its minimum diameter is greater than screw 2 diameter, has the mobility of certain orientation bottom it, be convenient to screw 2 lower end and combine with screwed hole 5 when making screw 2 penetrate through hole 4 with through hole 4.
This utility model is in concrete operation process, according to rib 6 fracture site, number, get corresponding angular cut or vertical incision, successively cut each layer of thoracic wall, peel off rib upper limb periosteum, after giving fracture site reset, anatomical form rib semi-surrounding compression fixator is fixed (moulding if desired).Then give on corresponding rib and hole, after choosing appropriate length screw, screw via through holes 4, epicostal hole are fixed on screwed hole.
This utility model adopts semi-surrounding instead of encircles structure, can be inserted fixing, and intercostal nerves, blood vessel is all positioned at rib lower edge on rear side of anterior axillary line, both reduce operation wound, additionally reduce intercostal nerves, blood vessel injury risk by rib 6 upper limb.Adopt upper and lower plates condensation technique, internal fixation screw 2 is directly combined with lower plate 102 screwed hole 5, stressed in rib 6 by upper and lower plates, minimizing rib 6 surface pressure, and fixation and screw 2 do not stress in rib 6, decreases rib 6 splitting and internal fixtion and to get loose probability.Operation technique is simple, operating technology is easily grasped, and reduces operation wound, shortens operating time, thus is beneficial to patient's recovery and reduces operation risk.
This utility model can reduce intercostal nerves blood vessel injury, reduces osseous tissue damage, the fixing pressurization of upper and lower plates, fixation, reduces hold-down screw and to get loose probability.
