Abstract
The utility model discloses a ware is demolishd to memory alloy coaptation board, including the casing of a rectangle tubulose, the arm lock on two guide bars rotate to be connected respectively to two guide bars of slidable mounting in the casing, and the pulling frame with two guide bar fixed connection is established the casing outside just to the cover, two arm lock symmetry sets up, and the tip is buckled in opposite directions and is formed pull -up portion under two arm lock, it is used for ordering about the extension spring that two arm lock lower extremes are close to in opposite directions to be connected with between two arm lock lower parts, pulling frame lateral wall has two arm -ties with the position shaping of pressing mouthful homonymy. Carry the staple bolt arm of memory alloy coaptation board through two arm lock, the rethread press down in opposite directions pulling frame and casing with the staple bolt arm to the pull -up toward the casing in, treat the staple bolt arm and is all pulled out the back, press down the arm lock upper end and make pull -up portion and staple bolt arm break away from, after pulling out the staple bolt arm one by one, can accomplish removing of coaptation board, convenient operation is swift.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of remover being exclusively used in dismounting memory alloy plate osteosynthesis.
Background technology
At present when removing memory alloy plate osteosynthesis, do not have special instrument, it is convenient not to remove, and the operating time is longer.Research and develop the eager desire that a kind of specific purpose tool being convenient to remove memory alloy plate osteosynthesis is orthopedist.
Summary of the invention
Technical problem to be solved in the utility model is: the deficiency existed for prior art, provides a kind of simple and compact for structure, can remove the remover of memory alloy plate osteosynthesis in direction.
For realizing the object of this utility model, be achieved by the following technical solutions: a kind of memory alloy plate osteosynthesis remover, include the housing of a rectangular tubular, be slidably mounted on two guide posts in housing, be rotatably connected on the jig arm on two guide posts respectively, be set in housing outer and be fixedly connected with two guide posts pull frame; Described housing upper end is closed, and housing upper end forms the recessed depressed part in a centre; Housing bottom forms the positioning port in order to coordinate with the anchor ear arm width of memory alloy plate osteosynthesis; Described housing two relative walls form two groups and coordinates with two described guide posts the targeting port be slidably connected; Another two relative walls of described housing form two pressing mouths stretched out with described jig arm upper end; Two described jig arm are symmetrical arranged, and two jig arm bottoms are bent to form pull-up portion in opposite directions; Be connected with between two jig arm bottoms to order about the extension spring close in opposite directions of two jig arm lower ends; The described frame sidewall that pulls forms two arm-ties with the position of pressing mouth homonymy.
Compared with prior art, the beneficial effects of the utility model are: the anchor ear arm being clamped memory alloy plate osteosynthesis by two jig arm, again by pressing in opposite directions pull frame and housing by anchor ear arm in housing to pull-up, after anchor ear arm is all drawn out, pressing jig arm upper end makes pull-up portion and anchor ear arm depart from, after being pulled out one by one by anchor ear arm, the dismounting of blade plate can be completed, convenient to operation.
