Key Feature:


1.Adopted brushless motor matched with lithium battery, featuring compact size, high torque and extended service life. The lithium battery is lightweight with large capacity, supporting 3 hours of continuous no-load discharge, fully meeting the demands of various complex surgical procedures.


2.This is the first domestic device featuring an integrated drive control system and battery, which differs from traditional models with built-in non-removable control systems inside the handpiece. The advantages of this design are as follows: the control system can be detached together with the battery during high-temperature and high-pressure autoclave sterilization, preventing damage to core electronic components in sterilization cycles and greatly prolonging the equipment’s service life.


3.The drive control system and battery can be easily disassembled. If the control system malfunctions, only the control unit needs to be replaced in later maintenance, without shipping the whole machine back to the factory for disassembly and repair. This eliminates cross-border shipping troubles, cuts transport time and costs, and significantly optimizes after-sales service.

Features of Oscillating Saw


High oscillation frequency shortens surgical time and delivers efficient cutting performance. The unique double-row tooth design of saw blades offers superior wear resistance and reduces operating costs. The saw blades integrate optimal hardness, toughness, length and width to produce smoother cutting surfaces on bone.


Features of Hollow Drill


It features a 4.2 mm hollow inner diameter to pass various guide wires, equipped with full professional interfaces compatible with soft drill intramedullary reaming attachments of all mainstream brands. The spindle and chuck are tightly fitted without welding, greatly improving concentricity and enhancing surgical outcomes.


Features of Bone Drill


The speed and torque reach an optimal balance to ensure smooth drilling and shorten operation duration. The spindle and chuck adopt tight non-welded fitting for excellent concentricity, with axial runout less than 30 μm (3 wire). It supports long single continuous working time to avoid surgical interruptions.


Features of Reciprocating Saw (Sternum Saw)


Equipped with sector gears for low noise and a long 4.2 mm reciprocating stroke. The elastic saw bow design prevents blade fracture and minimizes injury to surrounding soft tissues; high reciprocating frequency effectively shortens surgical duration.


Features of Acetabular Reamer Drill


Delivers ultra-high torque, the maximum torque among domestic reaming drills. It enables smooth, effortless acetabular replacement surgeries, equipped with complete quick-coupling interfaces compatible with attachments from all major manufacturers. It boasts outstanding concentricity and superior bone reaming effects.
