Abstract
The utility model discloses a kind of memory alloy rib bones plate, flat stringer including having 90-180 side angle degree, the two sides of flat stringer be symmetrically arranged with it is several encircle arm and be located at flat stringer most both ends encircles arms equipped with end tooth, encircle arm and be located at using flat stringer middle position as the both ends in line of demarcation and be located at each pair of arm of encircling of flat stringer wherein one end and form ellipsoidal structure, form circular configuration positioned at each pair of arm of encircling of the flat stringer other end.The end tooth of the utility model can prevent bone plate axial float, reinforce fixing；Meanwhile the structure of the utility model is designed according to aft rib bone physiological structure, can be reinforced fixing, normally be healed conducive to bone close to bone after installation；The acyclic folded arm in the middle position of flat stringer, can avoid rib cage fracture, injury region, and compressing of the arm to bone stump is encircled in elimination.It is implanted into the utility model surgical procedure, takes out easy to operate, can be shortened operating time, effectively increase surgical result and life in patients.
Description
Technical field
The utility model belongs to the field of medical instrument technology, and in particular to a kind of memory alloy rib bone plate.
Background technique
Human body rib cage is the bone for protecting the organs such as lung, heart, liver, is the framework in entire thoracic cavity.It is made because unexpected
Many at the patient of fracture of rib, fracture can be brought great pain to patients and inconvenience, especially rib cage aft rib position are fractured,
Because rear portion ribbed shape is different from front side ribbed shape, general instrument can make aft rib malunion.Generally during surgery frequently with
Bone plate is fixed at rib cage knochenbruch by encircle type metal bone fracture plate by encircling pawl, and re-treatm ent takes out after knochenbruch healing.Specially
Benefit number discloses a kind of encircle type metal bone fracture plate for 201420635714.5 patent, which includes: mainboard, symmetrically sets
Several fixed jaws of mainboard two sides are placed in, mainboard is equipped with screw hole, and screw hole is cone shaped countersink, and screw hole is longitudinally arranged in master
On plate and screw hole is equidistant apart from mainboard two sides, and fixed jaw end is equipped with flat contact plate, and mainboard both ends are equipped with arc
Notch.But there is following 2 aspects in the bone plate: 1, the physiological structure of skeleton is considered not in structure, such as
Fruit bone plate will cause after aft rib position is fixed and encircle pawl and not encircle in place, only screw is fixedly connected, and causes bone not
Energy healing or malunion and the risk for increasing product fracture.2, the bony structures of human body rib cage bone are not accounted for, if
Bone plate uses screw fixtation, takes out screw after suffering from knitting, will cause the secondary damage of bone.Based on above two original
Cause, existing encircle type metal bone fracture plate Shortcomings.
Utility model content
Purpose of the utility model is to solve the technical problems existing in the prior art, provide after a kind of installation close to
Bone is conducive to suffer from bone and normally heals and be implanted into, takes out easy to operate, can be shortened operating time, improve surgical result
Memory alloy rib bone plate.
In order to achieve the above object, the utility model uses a kind of following technical scheme: memory alloy rib bone plate, packet
It includes with 900-1800The flat stringer of side angle degree, the two sides of the flat stringer be symmetrically arranged with it is several encircle arm and be located at it is flat
Stringer most both ends encircle arm equipped with end tooth, it is described encircle arm be located at using flat stringer middle position as the both ends in line of demarcation and
Each pair of arm of encircling positioned at flat stringer wherein one end forms ellipsoidal structure, encircles arm positioned at flat each pair of of the stringer other end
Form circular configuration.
Further, the end for encircling arm is arc-shaped.
Further, the flat stringer is the arc beams that radius is 30-150mm.
Further, the arm of encircling is 2-6 pairs.
Further, the flat stringer and encircle arm be structure as a whole and material be Ultimum Ti.
The utility model has the advantages that the memory alloy rib bone plate of the utility model compared with the prior art
Mainly include flat stringer, be symmetricly set on flat stringer two sides it is several encircle arm and most both ends be set encircle on arm
End tooth, end tooth can prevent bone plate axial float, reinforce fixing；Meanwhile wherein each pair of of one end encircles arm positioned at flat stringer
It forms ellipsoidal structure, encircle arm formation circular configuration positioned at each pair of of the flat stringer other end, be raw according to aft rib bone
Structure design is managed, can reinforce fixing, normally heal conducive to bone close to bone after installation；The middle position of flat stringer without
Arm is encircled, rib cage fracture, injury region can be avoided, compressing of the arm to bone stump is encircled in elimination.It is planted in the utility model surgical procedure
Enter, take out easy to operate, can be shortened operating time, effectively increase surgical result and life in patients.In addition, this reality
Be with the novel end for encircling arm it is arc-shaped, be conducive to avoid rib nerve during installation, be avoided that intercostal nerve compression forced labor
Raw pain.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the top view of Fig. 1；
Fig. 3 is the structural schematic diagram that each pair of ellipsoidal structure of the utility model encircles arm；
Fig. 4 is the structural schematic diagram that each pair of circular configuration of the utility model encircles arm.
The utility model appended drawing reference meaning is as follows: 1, flat stringer；2, arm is encircled；3, end tooth.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figs 1-4, a kind of memory alloy rib bone plate, including have 900-1800The flat stringer 1 of side angle degree,
Flat stringer 1 is the arc beams that radius is 30-150mm, and the two sides of flat stringer 1 are symmetrically arranged with 2-6 to encircling arm 2 and be located at flat
The flat most both ends of stringer 1 encircle arm 2 equipped with end tooth 3, flat stringer 1 with encircle that arm 2 is structure as a whole and material is that NiTi is remembered
Recall alloy, encircles arm 2 and be located at using flat 1 middle position of stringer as the both ends in line of demarcation and be located at flat stringer 1 wherein one end
Each pair of arm 2 of encircling forms ellipsoidal structure, encircles the formation circular configuration of arm 2 positioned at each pair of of flat 1 other end of stringer, encircles arm
2 end is arc-shaped.
The memory alloy rib bone plate of the utility model: being put into sterile brine ice by specifically used method when operation,
It is allowed to after being fully cooled in brine ice to encircle arm 2 with specific purpose tool and be expanded to be open to be greater than to suffer from bone outer diameter, it is then right
It notch and removes tissue exposing at knochenbruch and suffers from bone, bone is suffered from reduction, which is placed in fracture, with disappearing
Scorchingly hot SS saline soaked gauze hot compress memory alloy rib bone plate makes to encircle the reset of arm 2, is securely fixed in fracture, pacifies
It installs into.After suffering from knitting, notch is needed when taking out memory alloy rib bone plate, removing tissue exposes memory alloy rib synthetism
Plate, rejecting are enclosed in the poroma encircled on arm 2, and the gauze cold compress memory alloy rib bone plate impregnated with disinfection brine ice is used
Specific purpose tool can easily take out.
