Abstract
The utility model discloses an internally fixing device for sacroiliac joint anatomical plate, which comprises a sacrum support rod (5) and a sacrum screw (1) and a universal mobile screw (6) matched and connected with the rod. The utility model is characterized in that: a polygonal connection steel plate is connected with one end of the sacrum support rod; two rows or more nail holes are arranged laterally from up to down on the connection steel plate; the number of each row of nail holes is confirmed according to the width of the connection steel plate. The fixing type of the device is scientific and reasonable and adapts to bio-morph of a pelvis for human body; the fixing device is arranged along the lateral surface of the pelvis and is tightly arranged together with the lateral surface of the pelvis, thereby forming a new combination structure similar to the role of an arch bridge; two rows or more of nail holes arranged on the fixing device enable the pelvis firmer; no remarkable difference exists between the straining, the displacement, the rigidity and the limit load and normal pelvis, thereby being superior to prior internally fixing mode. The utility model has the advantages of simple structure, convenient operation and use and safety and effectiveness.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specially a kind of sacroiliac joint anatomical plate inner fixing device.
Background technology
Pelvis C type fracture is more common in vehicle accident, high-altitude high-energy damage such as fall, and is all unstable on vertical and horizontal direction, is the most serious one type of damage in the fracture of pelvis, and it treats difficult, and complication is more.Chinese scholars is advocated positive open reduction internal fixation treatment at present, to reduce its disability rate.Various in recent years operation fixing meanss are increasing, as sacrum rod fix, the sacro-iliac joints screw is fixed, reconstruction plate, S1 screw be in conjunction with GaLveston technology internal fixation etc.Sacrum rod has the ability of good anti-vertical shear, but almost can't reverse; When adopting the sacro-iliac joints screw fixedly, it easily causes caving in of nail tail loosening in the single-point contact of ilium face; Reconstruction plate has certain anti-vertical shear and anti-torsion ability, but its fixed range is limited; The S1 screw is that single rod inserts the bone wing in conjunction with GaLveston technology internal fixation, has the fine motion between rod and ilium.At present existing 03210706.4 sacral screw is in conjunction with the patent of rod-plate inner fixing device, and it cooperates with pelvis by be connected the strip connection steel plate that is provided with single dog holes with rumpbone supporting rod one end, has problems such as fixation poor performance.More than the biomechanical property of these factors influence internal fixation, and there are shortcomings such as specification requirement height, big, the strong insufficient rigidity of operation wound, nerve and blood vessel injury complication be more in various art formula.
The utility model content
The purpose of this utility model is to overcome the above-mentioned problems in the prior art, and design provides a kind of technical scheme of sacroiliac joint anatomical plate inner fixing device of the biological structure that meets human pelvis.
Described sacroiliac joint anatomical plate inner fixing device, comprise the rumpbone supporting rod and be mated and connect sacral screw and the universal active screw that is provided with, it is characterized in that the connection of rumpbone supporting rod one end is provided with polygonal connection steel plate, described connection steel plate is horizontally set two or more rows nail hole from top to bottom, and every dog holes number is determined according to the width of the connection steel plate of present position.
Described sacroiliac joint anatomical plate inner fixing device is characterized in that described connection steel plate is triangle or trapezium structure, and the arrangement in corresponding nail hole is pyramid structure from top to bottom.
Described sacroiliac joint anatomical plate inner fixing device is characterized in that described connection steel plate thickness dwindles from top to bottom gradually, and the base angle is arc-shaped structure down.
Described sacroiliac joint anatomical plate inner fixing device is characterized in that the rumpbone supporting rod and to be connected steel plate one-body molded.
Described sacroiliac joint anatomical plate inner fixing device is characterized in that sacral screw is connected by nut and connector, and connector is fixedlyed connected with the rumpbone supporting rod with set bolt by the through hole that is provided with on it.
Described sacroiliac joint anatomical plate inner fixing device, it is characterized in that universal active screw by its upper end the tiger groove fixedly connected with the rumpbone supporting rod with corresponding nut.
Described sacroiliac joint anatomical plate inner fixing device is characterized in that following closely the outer little tapered structure of imperial palace of bore dia.
Above-mentioned sacroiliac joint anatomical plate inner fixing device, fixed form is scientific and reasonable, the biomorph that meets human pelvis, fixing more stable, this fixture is along the side of pelvis, make itself and pelvis side be close to layout, the effect of similar arch bridge, constitute new combinative structure with pelvis, the two or more rows nail hole that is provided with on the fixture, it is more firm to make it be connected ground with pelvis, and its strain, displacement, rigidity, ultimate load and normal pelvis there was no significant difference, be better than existing internal fixation mode, this apparatus structure is simple, easy for operation, safe and effective.
Description of drawings
Fig. 1 is this utility model structural representation;
Fig. 2 is for connecting the steel plate structure sketch map.
Among the figure: 1-sacral screw, 2-nut, 3-connector, 4-set bolt, 5-rumpbone supporting rod, the universal active screw of 6-, 7-nut, 8-connect steel plate, 9-follows closely the hole.
The specific embodiment
Below in conjunction with Figure of description, technical solutions of the utility model are described further by embodiment.
As shown in the figure, biological structure according to human pelvis, the connection of rumpbone supporting rod 5 one ends is provided with polygonal connection steel plate 8, connecting steel plate 8 is triangle or trapezium structure, the arrangement in corresponding nail hole 9 is pyramid structure from top to bottom, and the effect of nail hole 9 is to strengthen itself and the fastness of pelvis, and the little tapered structure of imperial palace outside should nail hole 9 diameters, purpose is to make things convenient for screw to knock in pelvis, adds stiff stability.These connection steel plate 8 thickness dwindle from top to bottom gradually, and down the base angle is arc-shaped structure, and itself and pelvis are fitted more closely and can be not sharp excessively because of the bight, damage pelvis.Relative set sacral screw 1 and universal active screw 6 on the rumpbone supporting rod 5, sacral screw 1 is connected by nut 2 and connector 3, connector 3 is fixedlyed connected with rumpbone supporting rod 5 with set bolt 4 by the through hole that is provided with on it, and universal active screw 6 is fixedlyed connected with rumpbone supporting rod 5 with corresponding nut 7 by the tiger groove of its upper end.
During use, on bone surface, get CCP,,, generate curved surface by these curves again with the horizontal secant of successive spline curve fitting with 2 hypotenuses of sectional spline curve fitting by certain dissection design.Press rumpbone supporting rod 5 and the almost plane direction that is connected steel plate 8, knock in screw on 9 positions, nail hole on the curved surface, the radius parameter that connects the fillet cutting of 8 times base angles of steel plate is 3mm, and curved surface is fitted tight with pelvis.
