Product Features

The Lapoc-SL prosthesis system is a system designed with the objective of being simple, light, and safe. With the following features, it's ideal for older users.

SL義足全体像 Built with a minimum of parts, it allows you to sit cross-legged or in Japanese seiza fashion.
It contains only four components: a socket holder with turn-table mechanism, a short-axle knee with tube joint, a lower-thigh tube, and a single-axle ankle joint.

The length of prosthetic can be easily adjusted through the thigh and lower leg tube.

Adjustments to the socket connection and support as well as the angle can be easily made between the metal plate of the lower socket and the socket holder with turn-table mechanism.
By adding an adapter attachment, you can use a 100R double socket for the lower socket.

Adjustments to the socket rotation angle are easily made between the main thigh tube and the knee joint.

The user can choose from two types of knee joints: an auto-locking manual-release knee joint or an auto-locking semi-free knee joint.
Both are the same length, so substituting one for the other does not change the length of the prosthetic. The knee lock can be released by pulling lightly on a waist-high cable.

The auto-locking semi-free knee joint allows you to walk with a cleaner gait than normal auto-locking knees.
There is no danger of falling over when the knee bends, and the knee bends by about 30° while walking.

The single-axle ankle joint allows sitting in Japanese seiza fashion without doing anything special.
A rubber band is used in place of the heel rubber, allowing minimum-force plantar flexion. The shape of the ankle is also nice.

There is no worry of damaging the cover over the knee area.
You can achieve an outer appearance similar to that of exoskeletal prostheses, divided at the knee joint into upper and lower sections.

The overall weight of the leg prosthesis is 2.0–2.3 kg.

Four Steps to Achieving the Right Fit

STEP 1

SL0250: Socket Base Module with Turn-Table Mechanism
A turn-table mechanism is combined with a tube to form a single unit, and the knee height can be adjusted by cutting the tube.
Adjustments to the socket connection and support as well as the angle can be easily made between the metal plate of the lower socket (M0205, M0206, or M0280) and the socket holder with turn-table mechanism.
If you use an adapter attachment, you can use a 100R double socket for the lower socket.


STEP 2

SL0701: Auto Locking, Manual Release Knee Joint (Lightweight Model)
Identical right and left sides, easy adjustment, emergency knob included. With the turn-table mechanism incorporated, upper knee space is reduced by 55 mm. (using SL0250)


SL0710: Auto-Locking, Manual Release Knee Joint Designed for Two-Piece Covering
This variant offers dual-action lock release using the front button or the cable. By adding a covering to the knee surface, you can achieve an outer appearance similar to that of exoskeletal prostheses, divided at the knee joint into upper and lower sections.


SL0720: Semi-Free Knee Joint
The semi-free knee joint allows you to walk with a cleaner gait than normal auto-locking knees. It allows knee flexion of up to 30 degrees and prevents any further bending. In addition, it allows the user to clear the floor without toe dragging during the swing phase, eliminating concerns about tripping and falling.


STEP 3

SL0810, SL0811: Carbon Tubes with Internal Titanium Film
With their internal titanium film, these tubes are designed to be 40% lighter than aluminum tubes. When using an SL0810 or SL0811 carbon tube, you should insert the attachment plugs into both ends of the tube.


STEP 4

SL1010: Rubber Loop Ankle Joint

  1. Lightweight. (173 g)
  2. It's compact, so it's easy to add padding or a covering to it.
  3. Adjustment of sagittal plane alignment is possible by changing the height of the dorsal flexion bumper.

SL1020: Rubber-Seated Ankle Joint

  1. This ankle joint uses a rubber base and allows multi-axle motion.
  2. Different bumpers can be chosen according to the user's weight and activity level. (three types each for rubber bases, dorsal flexion bumpers, and plantar flexion bumpers)
  3. Simple structure and lightweight. (260 g)

The Concept

This product was developed in order to show consideration for users through surprising lightweightness and optional plans.

We want to deliver more natural movement and a more comfortable user experience.
It was with that "more" in mind that we developed the Lapoc-SL leg prosthesis system. We have many different parts available among those four steps that make up the leg prosthesis. We've developed many leg prosthesis components to provide a better fit for the user's body type and movements. Since these parts all have simple designs, we've reduced the weight of the prosthetic leg itself and all other troublesome issues as much as possible.
Because your daily life relies on it, and because it becomes a part of your body.
