Responses- shuttle lock with suction

Thanks to all who took the time to respond--this is very helpful. Coyote Design was by far the most recommended. Also mentioned were Ohio Willowwood and PDI.




My original Question:

I am looking for recommendations for a pin lock that is air-tight so I can use
a suction sleeve as a supplementary means of suspension. I would like to know
reliability, ease of fabrication, ease of replacing a faulty unit, cost, etc.

suction as the sole means of suspension (based on a sample I showed her.) And
she wants to have the option of using only the pin if she deems the suction a
failure. An air-tight pin lock gives us the option to use both suspension
methods together, or either individually.

Coyote Air Lock. Have had good success.

coyote design makes a lock for this method
-----------------------------------------------------------------------------------
Take a look at Coyote Design Air Lock System. Fabrication is a little different
then hockey puck drop in style locks, but well worth it. One you have the pin
and lock aligned together (No Pin Dance to don) and second you have your
alignment of the foot transferable.
I have fit a lot of these, it became my standard lock. You may find on your
patient you may not need a sleeve to reduce/eliminate pistoning. Sealing air
from coming in or being pulled in distally prevents almost ALL motion. I would
test fit with Airlock, remove the pin from the liner (1-5ply fit) and patient
could walk around the room and the prostheses would not move or slide down.

Feel free to call me or check out Coyotedesign.com they have video's on fab and
product fitting.

Also, The cost of Air Lock may be a little higher (~ $100.00), The only parts
that may need/require service (Although I never had to service one) are the 3
Surgical steel springs and lock piece. These are very easily accessed by
removing the release button assembly.
The construction is a high impact plastic, the lock pins have a stainless steel
set pin through it. Air Lock is strong, light and durable. Don't worry about pin
wear, just make sure the lock is in alignment with the pin.
Many options for connecting components.
*In the 6 years using these locks I not once had a patient cram a sock in the
lock and get stuck*

I like coyote locks for precisely this Reason.

I like to use the coyote design air lock. I am actually doing a distal pressure
study between airtight locks and non-airtight locks. I am presenting this at the
continuing ed in Vegas. The study is pretty telling. In fact one of the test
that we do is actually walking the patient without the pin and just using the
airtight nature of the socket.

Most of the Willow Wood locks are suction also and easy to fabricate.

We use Coyote air lock with great success and no maintainence.
