This specialized instrument system is designed for the safe removal of broken screws following orthopedic trauma internal fixation, comprising 52 core tools that comprehensively address the key challenges of broken screw extraction—precise localization, screw head type adaptation, bone integration management, and safe efficient removal.
The set focuses on resolving critical pain points in broken screw removal procedures: engaging stripped screw heads, addressing callus encapsulation, adapting to various screw head types (Phillips, slotted, hex, star) and diameters, and achieving secure non-damaging grasping.
Instruments are manufactured from high-strength medical-grade stainless steel and carbide alloys, with critical working ends (e.g., trephine teeth, hollow saw blades, extractor threads) undergoing specialized reinforcement treatments to ensure efficient cutting and reliable grasping in bony environments.
With a core design philosophy of "Precise Localization + Targeted Management + Secure Extraction," the system utilizes modular driver systems, graduated trephines/hollow saws, specialized stripped screw extractors, and powerful removal devices to achieve minimally invasive, safe, and efficient removal of fractured portions of various metal implants (screws, small plate fixation screws).
This significantly reduces surgical difficulty and surrounding tissue damage risks, meeting the complex demands of broken metal screw removal following trauma internal fixation in long bones, pelvis, and periarticular regions.
Material Excellence
Instruments are constructed from premium stainless steels (05Cr17Ni4Cu4Nb, 420B, 316L, 304), offering high fatigue resistance. Electropolished surfaces minimize tissue friction and surgical trauma.
Comprehensive Coverage and Precision Adaptation
The set provides an extensive driver specification combination covering virtually all clinically common screw head types and sizes—including Phillips, triangle, slotted (3.0/6.0mm), square (1.2/1.5mm), hex (1.5-5.5mm), and star (T6-T30)—ensuring precise matching to different intact or minimally damaged screw heads. This establishes the most direct, effective tool foundation for conventional screw removal, preventing repeated attempts and damage escalation from tool mismatch.
Specialized Instrumentation for Efficient Obstacle Resolution
Addressing the most challenging broken screw removal issues of callus encapsulation and screw head stripping, the set includes graduated specialized processing tools. Multiple specification trephines (4.0/5.0/6.5mm) and serialized broken screw hollow saws (Ø2.0 to Ø8.0), combined with high-strength alloy drill bits (Ø4.0/5.0/6.0) and reamers, efficiently and controllably remove hyperplastic bone or bone cement encapsulating broken screws, precisely establishing removal channels and trimming screw peripheries. Specialized stripped screw extractors (2.0-4.0mm) utilize reverse-thread or cutting designs to forcefully embed into stripped screw heads, achieving reliable torque transmission and significantly improving stripped screw removal success rates.
Secure Grasping and Powerful Extraction
When screws cannot be removed via rotational methods, the set provides powerful mechanical grasping solutions. Including broken screw extractors in Ø3.5 and Ø4.5 specifications, these achieve secure, non-damaging powerful grasping of exposed screw shanks through precision tapered threads or mechanical clamping designs. Supplemented by heavy-duty screw holding forceps providing additional clamping force and fixation screw extractors for specific designs, combined with the leverage effect and stable control from T-type and straight quick-connect handles, this ensures safe, controllable removal of firmly integrated broken screws.
Systematic Design and Closed-Loop Workflow
The set features a clear design philosophy establishing a complete operational closed loop from "basic removal attempt → bone channel/screw periphery clearing → stripped screw head management → screw shank grasping and extraction." Instrument materials primarily include high-strength medical stainless steel and carbide alloys, with critical working ends (e.g., saw blades, extractor threads, drill bits) receiving specialized reinforcement treatments to ensure durability and efficiency in bony environments. Auxiliary tools like sharp hooks for meticulous debris and soft tissue clearing and round osteotomes for managing hard callus or limited osteotomy jointly ensure smooth, safe, and efficient surgical workflows, meeting the clinical demands of complex broken screw removal in extremities, pelvis, and joints.
Comprehensive Compatibility for Complex Clinical Scenarios
Through coverage of six major driver categories (Phillips, triangle, slotted, square, hex, star) with multiple precision specifications, and serialized hollow saws and trephines from Ø2.0 to Ø8.0, the set achieves gap-free adaptation for removing virtually all types, sizes (including rare specifications), and damage levels (intact, minimally damaged, stripped, callus-encapsulated) of metal internal fixation screws in orthopedic practice. Regardless of broken screw location in long bones, pelvis, or complex periarticular anatomical positions, surgeons need not compromise surgical plans due to instrument lack, significantly enhancing complex case management capability.
Specialized Instrumentation Resolving Core Operational Difficulties
Targeting the two major pain points of broken screw removal—difficult rotational extraction of stripped screws and callus/bone cement encapsulation—the set provides precise solutions: specialized stripped screw extractors utilize reverse-thread/cutting designs to forcefully embed into stripped screw heads for reliable torque transmission; graduated trephines/broken screw hollow saws combined with high-strength alloy drill bits efficiently and controllably remove encapsulating bone, establishing clear channels and precision-trimming screw peripheries. This targeted design greatly reduces operational difficulty, significantly improving single-attempt success rates for removing stripped and bone-integrated screws while avoiding additional damage from ineffective maneuvers.
Powerful Stability Ensuring Safe and Efficient Extraction
When conventional rotational removal fails, the set provides mechanical grasping solutions: broken screw extractors (Ø3.5/Ø4.5) with precision tapered thread designs and heavy-duty screw holding forceps achieve non-damaging, ultra-powerful stable grasping of exposed screw shanks. Combined with the powerful leverage and stable control from ergonomic T-type/straight quick-connect handles, this ensures safe, controllable en bloc removal of completely bone-integrated or firmly lodged broken screws, effectively preventing screw retention or secondary fracture risks during extraction.
Systematic Closed Loop Optimizing Entire Surgical Workflow
The set's logical closed-loop design of "basic attempt → channel clearing → stripped screw management → powerful extraction," complemented by auxiliary tools like sharp hooks for meticulous clearing and round osteotomes for hard callus management, ensures smooth operational workflow transitions. This significantly shortens procedure time, reduces intraoperative fluoroscopy frequency, decreases surgeon operational fatigue, and maximizes protection of surrounding healthy bone and soft tissue, ultimately achieving safe and efficient broken screw removal.
