Cruciate-Ligament-Inspired Compliant Joints: Application to 3D-Printed Continuum Surgical Robots
Summary
Additive manufacturing enables patient-specific surgical robots. A novel cruciate-ligament-inspired compliant joint (CLCJ) enhances bending stability in 3D-printed continuum robots, simplifying assembly and improving performance.
Area of Science:
- Robotics
- Biomedical Engineering
- Additive Manufacturing
Background:
- Additive manufacturing (3D printing) allows rapid fabrication of patient-specific surgical robots.
- Compliant joints simplify assembly of robotic systems compared to rigid-link mechanisms.
- Continuum robots require stable bending mechanisms for surgical applications.
Purpose of the Study:
- To introduce a novel cruciate-ligament-inspired compliant joint (CLCJ) for 3D-printed continuum surgical robots.
- To improve the bending stability and simplify the assembly of these robotic systems.
- To demonstrate the application and performance of the CLCJ in a prototype.
Main Methods:
- Detailed description of the tendon-driven CLCJ mechanism and its kinematic model.
- Finite Element Method (FEM) simulation to evaluate bending performance.
- Experimental testing of the CLCJ and a prototype CLCJ-based surgical robotic system.
Main Results:
- The CLCJ mechanism was successfully modeled and its bending performance was evaluated.
- FEM simulations and experimental tests confirmed the stability and effectiveness of the CLCJ.
- A functional prototype demonstrated the practical application of the CLCJ in 3D-printed continuum surgical robots.
Conclusions:
- The cruciate-ligament-inspired compliant joint (CLCJ) is a viable solution for enhancing bending stability in 3D-printed continuum surgical robots.
- This joint design simplifies assembly and improves the overall performance of patient-specific robotic systems.
- The CLCJ shows significant potential for advancing the field of minimally invasive surgery through additive manufacturing.

01:07Development of the Limb Synovial Joints

Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.

01:23Knee Joint
2.5K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

01:17Structural Joints: Cartilaginous Joints
3.0K
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...

01:16Bones of the Lower Limb: Femur and Patella
3.6K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

01:10Ankle Joint
2.0K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

01:16Structural Joints: Synovial Joints
5.2K
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...
