Abstract
The invention relates to the technical field of medical apparatus, in particular to a multi-direction locking steel plate for a long bone. The multi-direction locking steel plate for the long bone comprises a steel plate body and locking nails, wherein a plurality of first locking nail holes are formed in the steel plate body; a plurality of extension arms are symmetrically arranged on the two sides of the steel plate body, and a second locking nail hole is formed in each extension arm; the locking nails are arranged in part of the first locking nail holes and part of the second locking nail holes, accordingly, various combination manners are obtained; the steel plate body and the extension arms are of an integrated structure to form a cambered steel plate, and the cambered steel plate has a radian consistent with physiological radians of the long bones, thereby being more accordant with the shapes of the long bones of human limbs. The multi-direction locking steel plate can be beneficially combined in various manners based on patient conditions during operations by designing multi-row locking nails and locking nail holes, is enabled to be more firmly fixed, and can be adopted as the finally reliable selection for part of patients; moreover, second-phase replacement and fixing methods are not required.
Description
Technical field
The present invention relates to technical field of medical instruments, especially relate to a kind of multidirectional locking steel plate of long bone.
Background technology
Acropathy long bone fractures is more typically, account for about the 2/3 of fracture, at extremity fracture especially open fracture or invisible open fracture, although namely epidermis is complete, but because swelling, wiping contusion etc. cause that blood fortune is impacted, being likely to downright bad, ulceration person after a period of time, extenal fixation has the advantage that it is very big, shows themselves in that
(1) phase can accomplish fracture fixation, take into account skin soft tissue and process;
(2) the especially interior fixing myelitic incidence rate caused of osteomyelitis is significantly reduced;
(3) partial fracture distance joint relatively farther is not intended to joint motion, feasible early functional exercise;
(4) fracture of part extenal fixation effect stability can as final system of selection.
So, for long bone of limbs open fracture or invisible open fracture, extenal fixation is as first-selected fixing means, and this has become as the final conclusion of orthopaedics.
But, traditional external fixation is exterior fixation bracket, although through the tireless exploration of several generations, updating, current exterior fixation bracket has had very huge improvement, such as weight saving, and compound mode is diversified, multiple fixing means bilateral, changeable, etc., but, as the shortcoming of support itself, still exist.
For open fracture, its fixed effect is not good enough, and majority needs secondary to change fixing means; Exterior fixation bracket is provided with certain difficulty, and especially various combined methods are each disunity monolateral, bilateral, changeable such as; Patch VSD difficulty, wastes time and energy, vacuum suction less effective; This point is especially prominent, and part pad pasting is easy to by exterior fixation bracket friction, punctures ulceration, affects vacuum suction effect; And; the frameworks exposure of fixing long bone is external; prominent more apparent; in its fixing period; especially in the north or in cold season, the patient of cold injury often occur because exterior fixation bracket protection is improper, patients with functional exercise is also affected by impact to a certain extent simultaneously; to a certain degree affecting the self-confidence of patient, this is also the shortcoming that exterior fixation bracket itself cannot overcome.
Summary of the invention
The multidirectional locking steel plate of long bone that it is an object of the invention to provide, to solve the technical problem that there is fixed effect difference, vacuum suction weak effect in prior art.
The multidirectional locking steel plate of long bone provided by the invention, including steel plate body and locking nail, described steel plate body is provided with multiple first locking nail;
Described steel plate body lateral symmetry arranges multiple extension arm, and each described extension arm is respectively provided with one second locking nail;
Described locking nail is set in the described second locking nail of the described first locking nail of part and part, thus obtaining multiple combination mode;
The multidirectional locking steel plate of this long bone is by the design of multiple rows of locking nail and locking nail, can be conducive to operation carries out multiple combination according to patient's condition, and make it fixing more firm, some patients as reliably finally selecting, and can need not be changed fixing means the second phase.
Further, described steel plate body and described extension arm are integral type structure, form curved plate, and described curved plate has the radian consistent with long bone physiologic radian, more meets the shape of human limb long bone, fixing more firm.
Further, described first locking nail is arranged as a row, and described second locking nail is arranged as two rows;
The described first locking nail of one row second locking nail described with two rows is staggered; Be staggered make locking steel plate fixing more firm.
Further, described first locking nail and described second locking nail are respectively provided with multiple rows of;
Single described first locking nail second locking nail described with adjacent two rows is staggered.
Further, after described curved plate is fixed by described locking nail with long bone, the centrage of long bone is pointed at the tip of described locking nail.
Further, described locking nail includes thread segment and screw thread smooth section, and described thread segment is positioned at inside long bone, and described screw thread smooth section is positioned at inside skin soft tissue, it is possible to avoid soft tissue is carried out secondary insult.
Further, described curved plate length in the width direction is 5.5cm��8cm.
Further, the top in the width cross section of described curved plate is 1cm��2cm to the height of bottom.
Further; the inner side of described curved plate is additionally provided with vacuum suction layer; described vacuum suction layer is fixed on affected part by after described locking nail; the tissue that is wound can be protected; it is beneficial to damaged skin growth and the later stage processes; prevention is infected, and again owing to the design of curved plate makes vacuum suction layer airtight performance good, improves the effect of vacuum suction.
Further, the size in described vacuum suction layer length and width direction, respectively more than the size in described curved plate length and width direction, it can be avoided that curved plate is really up to the mark and make patient not feel well time fixing, also avoids skin soft tissue impaired.
The invention have the benefit that
The multidirectional locking steel plate of long bone provided by the invention is by the design of multiple rows of locking nail and locking nail, can be conducive to operation carries out multiple combination according to patient's condition, and make it fixing more firm, some patients as reliably finally selecting, and can need not be changed fixing means the second phase.
Additionally; by having the design of the curved plate consistent with long bone physiologic radian; and the design of vacuum suction layer, and each through being fixed on affected part after locking nail, it is possible to protect the tissue that is wound; it is beneficial to damaged skin growth and the later stage processes; prevention is infected, and again owing to the design of curved plate makes vacuum suction layer airtight performance good, improves the effect of vacuum suction; the face of hindering being beneficial to open fracture processes and postoperative function exercise, and especially near joint part fracture effect is more preferably.
