A kind of Combined type rib bone plate
Technical field
The present invention relates to the field of medical instrument technology, a kind of particularly Combined type rib bone plate.
Background technique
For the bone surgery that fracture of rib is carried out, in early days using with foraminate steel plate, in the bone of rib cage
Steel plate is bundled in broken rib cage on broken rib cage, or with steel wire with screw by two side perforatings of broken line by Interal fixation
On be fixed.This surgical procedure is cumbersome, and new damage may be brought to patient.With advances in technology, it is directed to rib at present
The carried out bone surgery of bone fracture starts using fixation bone fracture plate in the rib cage with fixed jaw.Rib with fixed jaw
Fixation bone fracture plate structure is simple in bone, operates more convenient in operation, and the histocompatbility of its material used is good, after operation such as
Without discomfort, without taking out.In rib cage with fixed jaw fixation bone fracture plate as it is a kind of it is special be placed in intracorporal medical instrument,
Whether the rehabilitation that the reasonability of its structure is directly related to sufferer is smooth, so require very stringent.
101669839 A of Chinese patent literature CN discloses a kind of rib-shaped memory embracing bone plate, by crossbeam and
It is constituted with each and every one several identical pawls of encircling of crossbeam one;It is characterized in that: encircling pawl is divided into left and right two groups, every group of middle ring
Spacing is equal between holding claw, encircles the distance between pawl two groups of crossbeam middle section and is every group and encircles spacing between pawl middle ring holding claw
2-8 times.On this kind of rib plate encircle the distance between pawl be it is determining, when coping with actual operation process, can not effectively,
The breaking part or damage position for reasonably avoiding rib cage increase the resulting pain of the wounded and other complication.
Summary of the invention
The technical problem to be solved by the present invention is can not effectively and reasonably avoid rib to solve existing rib cage pawl
The problem of breaking part or damage position of bone, the present invention provides a kind of Combined type rib bones plate, comprising: crossbeam and several cards
Connect and encircle pawl on crossbeam, can according to the actual conditions of patient to crossbeam length, encircle the quantity of pawl and encircle pawl clamping
Specific location on crossbeam is selected, and then makes to encircle breaking part or damage position that pawl avoids rib cage completely, adjusting side
Just, it is entirely avoided resulting pain and other complication.
The technical solution adopted by the present invention to solve the technical problems is: a kind of Combined type rib bone plate, comprising: crossbeam
Pawl is encircled with several be connected on crossbeam.

Portion's width is w, wherein w > h, is a spring beam on the downside of the card slot, when two rib cage pawl stress move toward one another, spring beam is forced to
Bending, enters in card slot, crossbeam is fixed in card slot by spring beam under the action of screen resilience convenient for crossbeam.Wherein card slot is transversal
Face shape can be isosceles trapezoid, or two base angles are the isosceles trapezoid of fillet.
Preferably, above-mentioned card slot is dovetail groove.
Preferably, the cross section of above-mentioned crossbeam is to match with card slot shape.
Specifically, above-mentioned crossbeam is equipped with several bayonets to match with card slot shape.
Specifically, the stop mechanism slided for preventing from encircling pawl along crossbeam is equipped between above-mentioned card slot and crossbeam.Wherein
Stop mechanism can be the frosted setting of card slot inner wall, be also possible to pit or protrusion setting.
Specifically, above-mentioned stop mechanism include several protrusions being arranged in card slot or pits and setting on crossbeam with card
Several pits or protrusion that several protrusions or pit in slot match.
Specifically, above-mentioned rib cage pawl and shackle member are integrally formed.
Specifically, above-mentioned crossbeam is made of biodegradable material.
Specifically, above-mentioned pawl of encircling is made of biodegradable material.
Wherein, biodegradable material can be high-molecular biologic degradation material, such as PGA, PLA, PCL and its copolymerization
Object is also possible to degradable metal and its alloy material, such as magnesium and magnesium alloy, titanium and titanium alloy.
The beneficial effects of the present invention are:
A kind of Combined type rib bone plate provided by the invention encircles pawl including crossbeam and several be connected on crossbeam,
Can according to the actual conditions of patient to crossbeam length, encircle the quantity of pawl and encircle specific location that pawl is connected on crossbeam into
Row selection, and then make to encircle breaking part or damage position that pawl avoids rib cage completely, it is easy to adjust, it is entirely avoided thus to generate
Pain and other complication.
A kind of Combined type rib bone plate provided by the invention, shackle member include a card slot, and it is h's that card slot, which has a width,
Upper opening, card slot bottom width are w, wherein w > h, are a spring beam on the downside of card slot, when two rib cage pawl stress move toward one another, bullet
Property beam is forced to be bent, and enters in card slot convenient for crossbeam, crossbeam is fixed in card slot by spring beam under the action of screen resilience, this
Clamping is securely, easy to use, does not need that the fixation encircled between pawl and crossbeam can be completed by other instruments.
