How it works

How do pin lock sockets work?

In a Pin Lock System, a pin is screwed into the lower end of the liner. The pin is inserted into a shuttle lock integrated into the socket, thereby connecting the residual limb to the prosthesis.

The system is easy to unlock using a simple mechanism. Shuttle lock fittings are frequently used with transtibial prostheses, making donning and doffing intuitive even for new prosthetic users.

No suspension sleeve is required with this system, which simplifies the daily routine and reduces the number of components to manage.

Benefits

Benefits of pin lock systems.

Quick and easy donning

Insert the pin into the shuttle lock and you're connected — no extra sleeves or vacuum systems required.

Intuitive release

A simple release mechanism lets you doff the prosthesis quickly, supporting independence at home and on the go.

Fewer components

No suspension sleeve simplifies the system and reduces the number of items you need to maintain and replace.

Reliable suspension

The mechanical lock provides secure, repeatable suspension throughout the day.

Widely compatible

Pin lock fittings are commonly used with transtibial prostheses and pair with a wide range of liner systems.

Easy to learn

The straightforward mechanism is well-suited to new prosthetic users and clinicians introducing first-time fittings.

Active Vacuum

Active vacuum provides the ultimate socket comfort by means of a pump unit creating a vacuum between the suspension sleeve and the liner.

Passive Vacuum

Passive vacuum, also referred to as a one-way valve, provides a high level of socket comfort when a vacuum is created between the suspension sleeve and the liner. When you begin to walk, the air is driven out of the socket to form a solid connection.
