The invention relates to a connecting rod construction. One or more than one elastic element is arranged on a connecting rod, and each elastic element is provided with one or more than one hollow slot, wherein the hollow slots on each elastic element are arranged at a bending side and/or an opposite side of the bending side, and when the hollow slots are arranged at the two opposite sides of each elastic element, the hollow slots are respectively arranged at the two opposite sides of the elastic element in an interval staggered manner; and the hollow slots of the elastic element are utilized, thus a gap space of the hollow slot can stretch out and draw back correspondingly when the connecting rod is under stress, elastic deformability of the connecting rod is improved, and the connecting rod can have the functions of bending, twisting, compressing, stretching, absorbing and buffering oscillation.
Description
Technical field
The present invention is relevant a kind of connecting rod structure, refers to especially a kind ofly be used to lock knot to be connected in nail solid between a plurality of nails of vertebrae, and the connecting rod of its body of rod tool strain usefulness structure.
Background technology
Vertebra in case displacement takes place or produce compressing or even muscle, ligament tissue are nervous on every side, all can directly influence the nerve in the vertebra, cause the terminal organ of neural supply indirectly; Muscle or secretion line body; Cause handicapped or pain, uncomfortable, this symptom of general therapeutic operation method capable of using fixing device for installing between the vertebra spine is to reach the effect of decompression; And known this treatment operation slightly is that first nail is implanted the suitable position that is fixed on upper and lower two joint vertebra spines respectively; And then lock knot sets firmly a connecting rod between two nails, makes to connect to one between nail and rigidly fix the bar structure, keeps the location between two joint vertebra spines in view of the above; And the support force of an appropriateness is provided, reach the usefulness of decompression.Only all inequality because of the generation combination angle that respectively saves vertebrae of human body; Rigidly fix the bar structure so aforementioned operation is installed, for the human vertebra that is curvature, have no the elastic space of angle fully; This result not only makes the postoperative mobility of sufferer receive great restriction; And the serious sense of discomfort that produces, especially as far as suffering from the patient of osteoporosis, this bar structure that rigidly fixes makes through regular meeting and plants nail and produce the bad problem of fixed steadiness; It is loosening or come off that nail takes place, very and will thereby hurt vertebrae and its peripheral cell tissue; Again; This rigidly fixes the bar structure will make original joint ineffective; Cause hypozygal must bear the function in original joint; And it can't provide pliable and tough, pooling feature like intervertebral disc, thereby makes that easily saving spinal joint up and down does sth. in advance aging or damage because of excessively using, and has necessity of improvement in fact.
Summary of the invention
Main purpose of the present invention is to improve foregoing problems; Be that a kind of connecting rod structure is provided, possess the usefulness of suitable flexible distortion, with in response to the vertebrae position that is installed in various various combination angles by connecting rod; Can simplify the operation technique difficulty; And the postoperative sense of discomfort of sufferer is improved, and natural mobility and range of movement between adjacent two vertebraes of therapentic part are provided, face the degeneration that saves vertebrae to reduce effectively.
Of the present invention time a purpose provides a kind of connecting rod structure; This connecting rod can be provided at different directions in response to user demand, and to have different elasticity distortion usefulness required to meet; Therefore connecting rod is possessed and meet flexible deformation's usefulness that vertebra operates engineering; Can assist to rebuild original natural mobility of vertebra and range of movement, guarantee the comfortableness when the sufferer vertebral body is movable.
For reaching above-mentioned purpose; Connecting rod of the present invention structure, it mainly is on connecting rod, to be provided with one or more than one elastic, and is provided with one or more hollow slots in this elastic; Utilize the hollow slots setting of this elastic; Make the gap space of connecting rod this hollow slots when stressed can produce corresponding stretching,, make this connecting rod possess function flexible, that reverse, compress, stretch, absorb and cushion concussion to promote the elastic deformability of connecting rod.
Particularly; This elastic use has high strength and corrosion proof material is processed into; Its material is to be selected from titanium alloy, tantalum alloy, rustless steel ... Deng alloy material; But practical range does not exceed with previous materials, and all kinds of macromolecule polymer materials (Biocompatible polymer) that are fit to plant the alloy material with good mechanical strength and anti-chemical that in human body, uses or bio-compatibility all are suitable for.
Particularly, the hollow slots on this elastic is to be set at the side of desiring curved side and/or its subtend, and when said hollow slots is arranged on subtend two sides of this elastic, and said hollow slots is to put subtend two sides that are separately positioned on this elastic alternately.
Particularly; The hollow slots set-up mode of this elastic can be made the setting of optimization parameter in response to the diastrophic performance of desire; And these parameter is set is the quantity offered of the well width, groove depth and the groove that comprise hollow slots, position, direction, angle etc.; Even the shape of hollow slots all belongs to it, for example: have more flexible usefulness for making connecting rod, can be in elastic be intended to the hollow slots that a crooked side be provided with a greater number; Or offer the wide hollow slots of larger slot, and offer darker hollow slots in subtend one side simultaneously.Therefore, the shape of offering quantity, position, direction, angle and hollow slots of the hollow slots width of the present invention's different choice capable of using, the hollow slots degree of depth, hollow slots etc. is provided with parameter, just can form the strain usefulness that connecting rod is desired to reach.
Particularly, this elastic and connecting rod are made of one piece.
Particularly, be to form one by engagement means between this elastic and the connecting rod; This engagement means, for example be screw togather, riveted, chimeric or welding manner; Understandable; In the application of reality, the structure of the junction of this elastic and connecting rod is to make corresponding structure design according to the various engagement means that adopts; This for example is to use when screwing togather means; Can be provided with screwed hole and external screw thread be set on connecting rod in this elastic, or external screw thread is set and on connecting rod, is provided with screwed hole in this elastic, screwed hole and the external screw thread that therefore makes the two arranged in pairs or groups each other and screwed togather and be integral.
