Abstract
The utility model discloses a spinous process reconstruction bone fracture plate which comprises a plurality of short drum coils with equal length, adjacent short drum coils are connected to a row through connecting bridges in parallel, and inner holes of the short drum coils are screw penetrating and fixing holes. The spinous process reconstruction bone fracture plate is applied to a spinous process fracture surgery, injured spine skeletons are convenient and stable to fix, the plurality of the short drum coils are arranged so that a plurality of fixing positions are provided for selection when fixation is conducted, both sides of each connecting bridge is arranged in an arc shape so that the bone fracture plate is good in tenacity and entire intensity, and each short drum coil is good in rigidity and not easy to deform when each short drum coil bears fastening force.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, relate in particular to a kind of spinous process Reconstruction plate.
Background technology
Spinal fracture is very common, accounts for 5%-6% of whole body fracture, and breast waist section note spinal fracture is common.Spinal fracture can and be grown spinal cord or end cauda equina injury, particularly fracture of cervical vertebra, and dislocation is associated with spinal cord injury person, it was reported to reach as high as 70%, can seriously disable even loss of life.The common male of spinal fracture is between twenty and fifty.How to be caused by indirect external force that buttocks or foot land when being fallen by eminence, impact external force fractures to being uploaded to breast waist section; Minority causes by direct external force, collapse such as the house weigh wounded, automobile presses and wounds or firearm injury.The person of being in a bad way can cause paraplegia, even threat to life; The simple compression fracture of malpractice also can be left over chronic back pain.
The stability of spinal column is determined by the bone of spinal column and the integrity of ligament structure, and the stable of posterior column structure also plays great role, and for the fracture of spinous process of rear pillar, past and tradition adopt expectant treatment, lack effective holder.The present domestic blade plate that there is no the spinous process special use, fixedly spinous process adopted wire binding more or did not deal with in the past, caused Lumbar spine, thereby produced various problems, accelerated scar hyperplasia, spinal canal stenosis etc. such as regression.
Summary of the invention
The present invention provides a kind of spinous process Reconstruction plate for problem related in the background technology.
Technical scheme of the present invention is: a kind of spinous process Reconstruction plate, formed by some isometric short cylinder circles, and to place side by side by cross structure between described each adjacent short cylinder circle and connect in a rowly, the endoporus of short cylinder circle is that screw fastens the hole.
As a kind of preferred, the endoporus of short cylinder circle is the truncated cone shape hole.
As a kind of preferred, the upper oral part of described each short cylinder circle endoporus is provided with screw cap and places restrictions on step.
As a kind of preferred, curved of the both sides of described cross structure.
As a kind of preferred, the quantity of described short cylinder circle is 2-12.
As a kind of preferred, described short cylinder circle is made by titanium alloy.
In sum, the present invention has the following advantages:
Blade plate structure of the present invention is in the fracture of spinous process operation, can put convenience and stably fix injured spinal column skeleton, and a plurality of short cylinder circles be arranged so that fixedly the time, to have more that the fixed position is available, and the curved blade plate that is arranged so that in the both sides of cross structure has preferably toughness and bulk strength, so that each short cylinder circle has preferably not changeableness of rigidity when bearing fastening force.
Description of drawings
Fig. 1 is the sketch map of present embodiment;
Fig. 2 is along the cutaway view of A-A among Fig. 1.
The specific embodiment
The invention will be further described with embodiment below in conjunction with accompanying drawing.
Shown in Fig. 1 to 2, a kind of spinous process Reconstruction plate is comprised of some isometric short cylinder circles 1, places side by side by cross structure 2 between described each adjacent short cylinder circle 1 to connect in a rowly, and the endoporus 11 of short cylinder circle 1 fastens the hole for screw.The endoporus 11 of short cylinder circle 1 is the truncated cone shape hole.The upper oral part of described each short cylinder circle endoporus 1 is provided with screw cap and places restrictions on step 12.Curved of the both sides of described cross structure 2.The quantity of described short cylinder circle 1 is 2-12.Described short cylinder circle 1 is made by titanium alloy.
Blade plate of the present invention only need to penetrate fastening bolt in the endoporus 11 in use, and being placed on screw cap, bolt head places restrictions on step 12, so so that bolt head is not easy to the blade plate separation, and endoporus 11 for truncated cone shape hole compressing fastening bolt so that have stronger adhesion between itself and the blade plate, and then so that the fixed effect of spinous process is more firm.
More than explanation only is explanation of the invention, so that complete enforcement this programme of those of ordinary skills' energy, but be not limitation of the present invention, those skilled in the art can make the modification that does not have creative contribution to present embodiment as required after reading this description, these all are not creative modifications.But as long as in claim scope of the present invention, all be subject to the protection of Patent Law.
