Product Analysis：Pulley-type Lumbar Fixation Brace

1. Basic Product Information

• Model: KDZJ-JZ-018
• Specification: One-size adjustable, fits S-4XL
• Material: Support sheets, elastic textile fabric, nylon pull ropes, etc.
• Core Structure: Double movable pulley rope-pulling system

2. Core Functional Highlights

Double movable pulley system (Core Selling Point) Adopting a pulley-rope structure, pulling the rope applies even compression on the waist. It features flexible and convenient operation. Users can independently adjust tightness and binding force without assistance from others to achieve compressive lumbar fixation.

Comparison with ordinary hook-and-loop Waist Braces: Conventional hook-and-loop braces are fixed by direct sticking, which tends to cause uneven pressure on both sides. The pulley structure enables synchronous bilateral tightening for betterbalanced force distribution on the waist.

3. Application Scenarios

1. Lumbar spine injury
2. External fixation during recovery after lumbar spine surgery
3. Lumbar disc herniation
4. Degenerative lumbar instability
5. Protection for lumbar muscle strain

4. Target Users

1. Post-operative rehabilitation group: Patients requiring external lumbar support and fixation during recovery after lumbar surgery.
2. Patient group: People suffering from lumbar disc herniation, degenerative lumbar instability and lumbar spine injury.
3. Daily-strain group: General users with lumbar muscle strain, long-term office-sitting habit, or those in need of waist support and protection.
