CAUTION
Mechanical damage to the product
Risk of injury due to change in or loss of functionality
• Use caution when working with the product.
•
If the product is damaged, check it for proper function and
readiness for use.
•
In case of changes in or loss of functionality, do not continue
using the product (see "Signs of changes in or loss of functionality
during use" in this section).
•
Take any necessary measures (e.g. repair, replacement, inspec-
tion by the manufacturer's customer service, etc.).
Signs of changes in or loss of functionality during use
Among other factors, changes in functionality can be indicated by an alte-
red gait pattern, a change in the positioning of the prosthetic components
relative to each other and by the development of noises.
3 5Y14 Tool
The 5Y14 Tool is available in three sizes to correspond with the 5R6 Modu-
lar Adapters. This tool makes it easier to accurately shape the distal end of
the plaster extension of a plaster positive or vacuum formed inner socket.
To calculate the amount of space needed for fabrication, measure the dis-
tance from the ischial tuberosity to the lower edge of the modular adapter
(a) and substract the tool depth (b): Size 1 = 50 mm, Size 2 = 45 mm, Size 3
= 35 mm (g. 1).
Draw reference lines on the positive to show the desired alignment. Use a
piece of polyethylene sheet material to extend the model (inner socket). Pour
plaster into the polyethylene sheet, lling to the marked height (correspond-
ing to the upper edge of the tool). Square off the end of the extension with
respect to the alignment lines (g. 2).
For a stronger bond, drive a few brads into the hardened plaster insert.
Coat the inner surface of the 5Y14 Tool with plaster parting agent cream.
Then, ll in with thin plaster (g. 3).
Set the plaster model precisely on the tool and align using the plumb lines
drawn on earlier (g. 4).
