Abstract
The utility model discloses a device is demolishd to memory alloy coaptation board, including the casing of a rectangle tubulose, two guide bars of slidable mounting in the casing rotate the arm lock of connecting on two guide bars respectively to reach the linkage frame of being connected with two guide bars, 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, linkage frame upper portion is rotated and is connected with an upward handle, the casing outer wall rotates and is connected with a lower handle, go up handle, handle rotation connection down. Clip the staple bolt arm of memory alloy coaptation board through two arm lock, thus the rethread press in opposite directions the handle, down the handle make the arm lock rise to draw the staple bolt arm toward the casing top, treat the staple bolt arm and all pulled out the back, press the arm lock upper end and make pull -up portion and staple bolt arm break away from, pull out the back one by one with the staple bolt arm, can accomplish demolising 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 detaching device 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 detaching device 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 detaching device, 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, and the linkage rack be connected with two guide posts;
Described 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;
Described linkage rack top is rotatably connected to a up knob, and described housing exterior walls is rotatably connected to a lower handle, and described up knob, lower handle are rotationally connected; Described housing forms the through hole passed for up knob;
Described linkage rack is fixedly connected with rotating shaft, and the leading section of described up knob forms the bar hole be connected with axis of rotation.
Preferably: described linkage rack includes the connecting plate of the inversion V-arrangement that two be arranged in parallel, and is connected to the linkage board between two connecting plate middle upper portion, and described rotating shaft is fixedly connected on described linkage board.
Preferably: the front portion of described up knob has two parallel plate bodys, and described lower handle, between two plate bodys, two described plate bodys all forms the described bar hole be connected with described axis of rotation.
Preferably: described housing exterior walls is welded with the hinged seat be rotationally connected with described lower handle.
Preferably: the both sides, position that described up knob and lower handle are rotationally connected are the arc of back-flexing.
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 up knob in opposite directions, lower handle makes jig arm rise thus be drawn above housing by anchor ear arm, 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.

Detailed description of the invention
With reference to the accompanying drawings detailed description of the invention of the present utility model is made a detailed explanation below.
According to shown in Fig. 1 to Fig. 3, the present embodiment is a kind of memory alloy plate osteosynthesis detaching device, includes the housing 1 of a rectangular tubular, is slidably mounted on two guide posts 3 in housing, be rotatably connected on the jig arm 2 on two guide posts respectively, and the linkage rack 4 be connected with two guide posts.
Described housing bottom forms the positioning port 11 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 12 be slidably connected; Another two relative walls of described housing form two pressing mouths 13 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 21 in opposite directions; Be connected with between two jig arm bottoms to order about the extension spring 7 close in opposite directions of two jig arm lower ends.
Described linkage rack top is rotatably connected to a up knob 5, and described housing exterior walls is rotatably connected to a lower handle 6, and described up knob, lower handle are rotationally connected; Described housing forms the through hole passed for up knob.
Described linkage rack is fixedly connected with rotating shaft 41, the leading section of described up knob forms the bar hole 51 be connected with axis of rotation.
Described linkage rack includes the connecting plate of the inversion V-arrangement that two be arranged in parallel, and is connected to the linkage board between two connecting plate middle upper portion, and described rotating shaft 41 is fixedly connected on described linkage board.
