From August 13 to 16, the 17th Annual Meeting of the Chinese Association of Orthopaedic Surgeons (CAOS 2026) was held in Jinan, Shandong Province.

At the event, Liangyi presented three new product lines: a universal positioning arm, a large-bone surgical power system, and a high-speed surgical power system.

The launches extend Liangyi’s product portfolio beyond conventional orthopedic instruments and surgical robot accessories, adding positioning and powered execution components used in orthopedic procedures.

Universal Arm Targets Flexible Positioning in Orthopedic Surgery

The first new product is Liangyi’s universal arm, designed as an auxiliary positioning device for orthopedic procedures.

In orthopedic robotic and minimally invasive surgery, instruments, retractors and other components often need to be positioned and maintained at specific angles throughout a procedure. Operating-room space is limited, while the surgical field can change as the procedure progresses. This places demands on both positioning flexibility and fixation stability.

Liangyi’s universal arm uses a multi-joint structure to provide a broader adjustment range. According to the company, the product is intended to allow surgeons to reposition and secure instruments more efficiently while reducing the space occupied by conventional supporting structures.

The product also reflects the growing role of supporting components such as positioning arms, fixation devices and end-effectors in orthopedic robotic systems.

Large-Bone Power System Covers Trauma and Joint Procedures

Liangyi also introduced a large-bone surgical power system, targeting procedures such as trauma surgery and joint reconstruction.

Powered surgical tools are widely used in orthopedic procedures for drilling, reaming, sawing and other bone-processing steps. Compared with smaller powered instruments, large-bone systems need to address higher load requirements while maintaining controllability during cutting and drilling.

The system presented at CAOS includes handheld powered instruments designed for different orthopedic operating scenarios. According to Liangyi, its development focused on handling, power output and compatibility with different surgical applications.

For orthopedic surgical robots, powered tools are also becoming more closely connected with robotic execution. Joint replacement and trauma systems may require dedicated saws, drills and other actuators that can be integrated with robotic planning and guidance.

Liangyi has previously supplied surgical instruments, saw blades and other components for orthopedic robotic systems. The addition of a large-bone power platform broadens the company’s coverage of the execution side of orthopedic surgery.

High-Speed Power System Reaches 95,000 rpm

The third launch is a high-speed surgical power system, with a maximum speed of up to 95,000 rpm, according to information presented at the event.

High-speed powered instruments are used in procedures requiring more refined bone cutting, grinding or shaping. Their applications can extend across multiple orthopedic surgical scenarios, where stable speed control and precise manipulation are important.

Liangyi said the system was developed around cutting efficiency and operational stability, with different handpieces and accessories intended to support varied procedural requirements.

Compared with conventional orthopedic instruments, power systems involve a broader combination of mechanical design, motor control, handpiece engineering, sterilization compatibility and consumable interfaces. For companies serving surgical robotics manufacturers, these capabilities also provide a basis for developing customized powered end-effectors.

Liangyi Expands Further Upstream in Orthopedic Robotics

The three product lines presented at CAOS 2026 broaden Liangyi’s orthopedic product portfolio.

The company has traditionally focused on orthopedic surgical instruments, precision components and accessories for surgical robots. Its portfolio includes products used in joint replacement, trauma and other orthopedic procedures, as well as surgical robot saw blades and related instruments.

With the addition of the universal arm and two powered surgical systems, Liangyi is extending its product coverage toward positioning, fixation and powered execution.

For orthopedic robot manufacturers, these modules form part of the hardware layer connecting surgical planning with intraoperative execution. End-effectors, powered tools, fixation components and other supporting devices are therefore important elements of system integration and surgical workflow design.

The latest launches further expand Liangyi’s upstream product portfolio around orthopedic surgery and surgical robotics.
