Abstract
The invention discloses a kind of memory alloy plate osteosynthesis remover, include the housing of a rectangular tubular, two guide rods being slidably mounted in housing, the jig arm being rotatably connected on respectively on two guide rods, it is set in the pulling frame that housing is outer and is fixedly connected with two guide rods；Two jig arm are symmetrical arranged, and two jig arm bottoms are bent to form pull-up portion in opposite directions；It is connected with to drive the opposite close extension spring in two jig arm lower ends between two jig arm bottoms；It is described to pull frame side wall to form two arm-ties with pressing the position of mouth homonymy.The anchor ear arm of memory alloy plate osteosynthesis is clamped by two jig arm, pull frame and housing by anchor ear arm toward pulling up in housing by pressing in opposite directions again, after anchor ear arm is drawn out, pressing jig arm upper end makes pull-up portion depart from anchor ear arm, after anchor ear arm is pulled out one by one, the dismounting of bone plate can be completed, it is easy to operate.
Description
Technical field
The invention belongs to medical instruments field, and in particular to a kind of remover for being exclusively used in removing memory alloy plate osteosynthesis.
Background technology
At present when removing memory alloy plate osteosynthesis, without special instrument, it is not convenient enough to remove, and the operating time is longer.
Research and develop it is a kind of be easy to remove memory alloy plate osteosynthesis specific purpose tool be orthopedist eager desire.
The content of the invention
The technical problems to be solved by the invention are：In view of the deficienciess of the prior art, provide a kind of simple in construction tight
Gather, can conveniently remove the remover of memory alloy plate osteosynthesis.
To realize the purpose of the present invention, it is achieved using following technical scheme：A kind of memory alloy plate osteosynthesis remover,
Include the housing of a rectangular tubular, two guide rods being slidably mounted in housing, be rotatably connected on two guiding respectively
Jig arm on bar, it is set in the pulling frame that housing is outer and is fixedly connected with two guide rods；Described housing upper end closing, and
Housing upper end forms the recessed depressed part in a centre；Housing bottom is formed to the anchor ear arm with memory alloy plate osteosynthesis
The positioning port that width coordinates；Two groups are formed on described two relative walls of housing and coordinates slip with two guide rods
The targeting port of connection；Two pressing mouths stretched out with the jig arm upper end are formed on the housing another two relative wall；Two
The individual jig arm is symmetrical arranged, and two jig arm bottoms are bent to form pull-up portion in opposite directions；Use is connected between two jig arm bottoms
To drive the opposite close extension spring in two jig arm lower ends；It is described to pull frame side wall to form two drawings with pressing the position of mouth homonymy
Plate；The pulling frame takes the shape of the letter U with the wall that two guide rods are connected, and the upper-end part of driving of the jig arm is in the lower section of arm-tie；It is described
Pull the gap that 1-2mm is left between frame and housing.
Compared with prior art, the beneficial effects of the invention are as follows：Memory alloy plate osteosynthesis is clamped by two jig arm
Anchor ear arm, then pull frame and housing toward pulling up in housing, after anchor ear arm is drawn out, to press anchor ear arm by pressing in opposite directions
Pressure jig arm upper end makes pull-up portion depart from anchor ear arm, after anchor ear arm is pulled out one by one, you can complete the dismounting of bone plate, operation side
Just it is quick.
Brief description of the drawings
Fig. 1, Fig. 2 are the structural representations of the present invention.
1st, housing；11st, positioning port；12nd, targeting port；13rd, depressed part；14th, mouth is pressed；2nd, jig arm；21st, pull-up portion；3rd, lead
To bar；4th, frame is pulled；41st, arm-tie；5th, extension spring.
Embodiment
The embodiment of the present invention is made a detailed explanation below according to accompanying drawing.
According to Fig. 1 and Fig. 2, a kind of memory alloy plate osteosynthesis remover described in the present embodiment, include a square
The housing 1 of shape tubulose, two guide rods 3 being slidably mounted in housing, the jig arm being rotatably connected on respectively on two guide rods
2, it is set in the pulling frame 4 that housing is outer and is fixedly connected with two guide rods；Described housing upper end closing, and housing upper end
Portion forms the recessed depressed part 13 in a centre；Housing bottom is formed to the anchor ear arm width side with memory alloy plate osteosynthesis
To the positioning port 11 of cooperation；Two groups are formed on described two relative walls of housing to be slidably connected with two guide rods cooperations
Targeting port 12；Two pressing mouths 14 stretched out with the jig arm upper end are formed on the housing another two relative wall；Two
The individual jig arm is symmetrical arranged, and two jig arm bottoms are bent to form pull-up portion 21 in opposite directions；It is connected between two jig arm bottoms
To drive the opposite close extension spring 5 in two jig arm lower ends；It is described to pull frame side wall to form two with pressing the position of mouth homonymy
Individual arm-tie 41；The pulling frame takes the shape of the letter U with the wall that two guide rods are connected, and the upper-end part of driving of the jig arm is under arm-tie
Side；It is described to pull the gap that 1.5mm is left between frame and housing.
In use, pressing jig arm upper end makes two jig arm clamp the anchor ear arm of memory alloy plate osteosynthesis, positioning port, which is stuck in, to be embraced
Arm and memory alloy plate osteosynthesis main body connected position are bound round, then pulls frame and housing by anchor ear arm toward in housing by pressing in opposite directions
Pull up, after anchor ear arm is drawn out, pressing jig arm upper end makes pull-up portion depart from anchor ear arm, and anchor ear arm is pulled out one by one
Afterwards, you can the dismounting of bone plate is completed, it is easy to operate.
