Below Knee Suspension Socket

---

A Base Lock Suspension Socket is a modern below-knee prosthetic socket system designed to provide secure suspension, comfort, and easy usage for transtibial amputees. This system uses a silicone or gel locking liner with a distal pin that locks into a shuttle lock mechanism placed at the bottom base of the prosthetic socket.

• Secure pin locking suspension system
• Easy donning and doffing
• Comfortable silicone/gel liner interface
• Improved stability during walking
• Durable and reliable mechanism
• Suitable for daily functional use

• Enhances patient confidence and mobility
• Reduces accidental prosthesis slipping
• Provides better prosthetic control
• Comfortable fit with cushioning liners
• Simple maintenance and easy handling

• Below-knee amputees
• Long and medium residual limbs
• Low to moderate activity users
• First-time prosthetic patients
• Elderly users needing secure suspension

• Pistoning may occur in long-term use
• Distal traction can cause skin issues
• Less suitable for very short residual limbs
• Lock maintenance required periodically

A Passive Vacuum Socket is an advanced below-knee prosthetic suspension system that uses a one-way expulsion valve to create vacuum pressure between the residual limb, liner, and socket. This vacuum helps maintain a secure fit by reducing air inside the socket during walking and movement.

• One-way vacuum valve system
• Secure suction suspension
• Reduced pistoning movement
• Better socket fit and limb control
• Improved comfort and proprioception
• Lightweight and low-maintenance design

• Enhances prosthetic stability
• Helps maintain residual limb volume
• Reduces friction and skin movement
• Improves walking confidence and gait
• Provides intimate socket fit
• Better energy transfer during ambulation

• Below-knee amputees
• Moderate to high activity users
• Patients requiring improved suspension
• Users with stable residual limb volume
• Individuals seeking enhanced comfort and control

• Higher cost than normal suspension systems
• Needs proper sealing for good suspension
• Slightly difficult to wear and remove
• Sweat may reduce comfort in hot weather
• Not suitable for all residual limb conditions
• Need to use Vacuum Machine for Casting.

An Active Vacuum Socket is an advanced below-knee prosthetic suspension system that uses a mechanical or electronic pump to actively create vacuum pressure between the residual limb and the socket. This continuous vacuum provides a highly secure fit, improved limb stability, and enhanced comfort during walking and daily activities.

• Mechanical or electronic vacuum pump
• Continuous active suction suspension
• Strong and secure socket fit
• Reduced pistoning movement
• Improved residual limb volume management
• Enhanced comfort and proprioception

• Excellent suspension and stability
• Better gait control and balance
• Improved comfort for long-term wear
• Reduced skin movement and friction
• Helps maintain healthy residual limb volume
• Increased confidence during walking

• Below-knee amputees
• Moderate to high activity users
• Active lifestyle patients
• Users requiring maximum suspension control
• Patients with stable skin condition

• Higher cost compared to traditional systems.
• Requires regular maintenance.
• Not suitable for all residual limb conditions.
• Need to use Vacuum Machine for Casting.
