hANDi hand orthose假肢模型分享

是fflood在2014年4月23日上傳至Thingiverse網(wǎng)站的目前項(xiàng)目還在更新中。原文地址為（有可能被墻）：https://www.thingiverse.com/thing:308124

歷史：
我們今年春天從上海收養(yǎng)了我們的兒子。
他有一個(gè)輕微的痙攣性腦癱病例，使得他的身體左側(cè)不能完美運(yùn)作。
他的左手一直彎曲著肌肉緊張。我們需要每天多次伸展和進(jìn)行不同類型的訓(xùn)練。
我有這個(gè)想法，但我沒有任何3D設(shè)計(jì)經(jīng)驗(yàn)。
但后來我的一個(gè)朋友給我發(fā)了一個(gè)鏈接來解決這個(gè)挑戰(zhàn)，這給了我新的動(dòng)力。
花了一些時(shí)間來學(xué)習(xí)一個(gè)軟件程序和很多從頭開始，當(dāng)我得到一個(gè)正確的設(shè)計(jì)我打印，測(cè)試，有時(shí)不得不重做，但現(xiàn)在我明白了:)
所以這是我對(duì)Thingiverse #AssistiveTech Challenge的貢獻(xiàn)
使用：
對(duì)于我兒子來說，這只手只是為了一個(gè)目的，伸展......但事實(shí)證明，他現(xiàn)在也可以把手握在他以前從未有過的直立位置。
這是一個(gè)巨大的獎(jiǎng)金，它在玩的時(shí)候真的會(huì)幫助他。
hANDi將手伸向“上手板”，伸出手。同時(shí)它伸出手指。
在設(shè)計(jì)添加到“筆架”后，我現(xiàn)在必須添加到此部分
是的，與此同時(shí)，他得到了他能夠畫出的拉伸，這真的有助于他掌握運(yùn)動(dòng)技能。坐下來看看他用手臂取得的進(jìn)展真是太棒了......太棒了!!!
手的其他目的是肌肉康復(fù)。彈簧張力的原因。
我希望這只手可以幫助其他孩子接受CP或某種手部傷害。
所以我確保做了設(shè)計(jì)，所以它可以在左手和右手使用;）
我還在環(huán)和手板之間增加了一個(gè)可選擇的手臂，它具有20度的向上角度，可以更加伸展。
關(guān)于大小，我們的兒子已經(jīng)4歲了，這個(gè)設(shè)計(jì)的指尖非常適合他...如果它不適合，只需縮小一點(diǎn);）或者問我，我會(huì)幫助你它:)如​​果你使用Fusion 360我可以邀請(qǐng)你到項(xiàng)目文件夾:)
另外......我有一些融合選項(xiàng)來提取文件。我是新手，所以我不知道最好分享哪個(gè)文件擴(kuò)展名？我見過有人上傳.STEP文件。
你想讓我這樣做嗎？
打印后，我在手臂環(huán)內(nèi)側(cè)和手掌頂部下方添加了一些柔軟材料。然后我用Velcro收緊它。
我用彈簧和釣魚線連接指尖。

易于打印的部件
使用支撐材料，臂環(huán)易于打印，寬大部分朝下。
同樣的指尖，指尖朝上站起來......他們需要支撐材料。
兩個(gè)臂，一個(gè)用于拇指，一個(gè)用于將環(huán)和板固定在一起，最好在側(cè)面印刷，帶有支撐材料。
使用支撐材料，手指板最好平放，手指浮動(dòng)。
添加：筆架打印平放，就像它坐在手上一樣�？姿�需的支撐材料;）
我打印所有的0層高度，支撐材料和50％填充，使部件強(qiáng)大，但也許它不必那么高。
我使用“printrbot簡(jiǎn)單金屬”沒有加熱床和糟糕的橋設(shè)置，所以有一個(gè)更好的打印機(jī)這些部分甚至不需要支持材料:)
其他需要的材料：
2個(gè)彈簧
6個(gè)M4螺釘和螺母
大約1米的釣魚線和谷歌搜索釣魚結(jié);）

一些柔軟的材料放在里面，使其舒適。
我是如何設(shè)計(jì)的：

這是我設(shè)計(jì)的第一步。 就在睡覺前我們坐下來做了這個(gè):)

我使用了Fusion 360，這是我做過的第一個(gè)真正的3D設(shè)計(jì):)版本1.0

所有部件加上Addon pennhoder（舊手環(huán)）

用筆筒的hANDi

使用釣魚線鎖定

使用這樣的鎖..只需將線槽穿過并用鉗子壓在一起:)

隨著新的手臂環(huán)！ 適合手臂更好，更舒適:)

Hitstory
We adopted our son from Shanghai this spring.
He has a mild case of Spastic Cerebral palsy that is making his left side of the body not working perfectly.
His left hand is bent with muscle tension all the time. We need to stretch and do different kinds of training several times a day.

I had the idea for this hand for i while but haven't had any experience in 3D design.
But then a friend of mine sent me a link to this challenge and that gave me new motivation.

It took some time to learn a software program and a lot of starting all over, and when I got a design right I printed, tested and sometimes had to redo, but now I got it :)
So this is my contribution for the Thingiverse #AssistiveTech Challenge

Use
For my son right now the hand was made for only one purpose, to stretch.. but it turned out that somehow he also can now hold the hand in a upright position he never could before.
that's a huge bonus, it will really help him when playing.
hANDi both stretch his hand out by pulling it up against the "overhand plate". At the same time it stretches his fingers up.
One thing I have to add to this section now after designing the add on "pen holder"
is that at the same time he gets the stretching he needs he can draw, and that really helps him with hit motor skills. It is amazing to sit down and see the progress he makes in using his arm.. amazing!!!

Other purposes for the hand is muscle rehabilitation. cause of the spring tension.
I hope this hand can help other kids to with CP or some kind of hand injury.
So i made sure to do the design so it can be used on both left and right hand ;)
I also added a alternative arm between the ring and hand plate that has a 20 degree upward angle for more stretch.

About the size, our son is 4 years old and the finger tips of this design is a perfect fit for him... if it doesn't fit, just scale it up a little ;) or ask me and I will help you with it :) If you are using fusion 360 I can invite you to the project folder :)
Also... I have some options in fusion to extract the files. I am new to this so I dont know what file extension is the best to share? I have seen some people upload .STEP files.
Do you want me to do that?

After printing I added some soft materials to the inside of the arm ring and under the plate that lays on top of the hand. Then i used Velcro to tighten it all up.
I used springs and fishing line to attach the fingertips.

Notes:
(some kind of error with the markdown in this section, I have tried to make understandable by adding < br > for new line.. hope it gets fixed)

Easy to print parts
Arm ring is easy to print standing up with wide part down, using support material.
The same with the fingertips, standing up with the fingertip facing up.. and they need support material to.
The two arms, the one for the thumb and the one that holds the ring and plate together is best printed on the side, with support material for the hook.
The over hand plate is best printed flat with the fingers floating.. using support material.
The add on: pen holder is printed flat down like it is suppose to sit on hANDi. support material needed for the holes ;)
I printed all with 0,2 layer height, support material and 50% infill to make the parts strong but maybe it doesn't have to be that hight.
I use a "printrbot simple metal" without heated bed and bad bridge settings so with a better printer some of these parts don't even need support material :)

Other materials needed:
2 springs
6 M4 screws and nuts
about 1 meter of fishing line and a google search on fishing knots ;)

Or use cable lug to lock line, see image a bit down on this page ;) (<--recommendation)
Download my design Knut 2 or Knut and use between spring and the fingers:
(image below)
Some sort of soft mateial to put on the inside to make it comfortable.

How I Designed This

This was the first step of my design. right before bed time we sat down and did this :)

I used fusion 360, this is the first real 3D design I have ever done :) version 1.0

Complete hANDi with updated parts including pen holder... version 2.0
YouTube and pics

Here is hANDi with my multi attachment Knut, find Knut here: http://www.thingiverse.com/thing:1075335

All parts plus Addon pennhoder (old hand ring)

hANDi with the pennholder

Make locks for the fishing line using

use the locks like this.. just thread the line trough and press together with pliers :)

With new arm ring! fits mush better to the arm and is more comfortable :)
