Surgical Device Design and Development
The design and development of surgical devices demands not only a deep and thorough technical expertise but also a comprehensive approach. At HaA PD, we have over thirty years of experience developing Class I, II, and III medical devices. From concept to commercialization, our team drives innovation within every step of the process from research to engineering, human factors design, regulatory strategy, and manufacturing optimization.
Core Focus Areas
We concentrate on several key areas of surgical medical devices development, ensuring we address both clinical needs and technological opportunities. Our expertise ranges from handheld instruments to integrated systems and targeted therapy delivery. We have deep expertise and experience in 5 key areas of surgical device development.
Handheld Surgical Tools
Handheld surgical instruments play a major role in the medical world. Whether our goal is to improve an existing design or create a new one, we design handheld instruments that prioritize ergonomics, surgeon control, clinical workflow, and manufacturability.
We apply human‑factors engineering early on, define use and task flows, and make sure that the device aligns with surgical requirements while meeting sterilization, durability, and regulatory needs. Using our industrial-design and mechanical-engineering expertise, we maximize shape, weight, balance, interface, tactile mechanics, and usability. This attention to detail makes our devices not just function clinically, but intuitive and dependable in practice.
Energy‑Based Systems
Systems that are based on energy, such as electrosurgical, ultrasonic, RF, microwave, or laser devices, present specific design challenges, such as power electronics integration, thermal management, sterility and safety, user-interface, and treatment verification. At HaA PD, we are well-versed in the design of systems where controlled energy delivery is the target of the therapy. Our expertise encompasses the entire system architecture, from the source of energy through the delivery interface, control electronics, embedded sensors, system safety interlocks, and manufacturing readiness. In each case, we meet regulatory requirements for biocompatibility, electrical safety, sterility, and performance qualification. The result is surgical devices that deliver energy-based therapy effectively and with clinical precision.
Fluidic and Jet‑Driven Devices
Fluidic and jet‑driven modalities deliver minimally invasive, high‑precision surgical capabilities for tissue cutting, irrigation, aspiration, drug infusion, etc. We design devices that safely manage fluid dynamics, pressure, flow, and jet behavior. Our engineering and design process allows for precision actuators, microfluidic control, medical-grade materials, integrated sensors for feedback, and clinical workflow usability.
We consider piping, tubing, flow‑paths, burst‑pressure safety, sterilization‑cycles, manufacturing‑scalability, and user‑interface in parallel. Thanks to our expertise, we can deliver devices for advanced surgical application areas such as water‑jet cutting, irrigation systems, and high‑velocity fluid delivery.
Optical and Illumination Integration
In today’s modern surgery, lighting and imaging are key, whether we’re talking about integrated lighting on handheld devices, fibre‑optic scopes, endoscopes, or image‑guided systems. To provide surgical teams with the visibility and accuracy they need, we combine optical hardware with mechanical and electronic systems.
We specialize in incorporating optical components, designing ergonomics for around lighting, and aligning optics with user workflow and safety standards. This includes LED‑based lighting within retractors, fiber optic visualization, and combined imaging modules for surgical hand‑instruments. We thus make sure of uniformity of light, provide intuitive controls for clinicians, and minimize shadows and interaction with sterile surroundings.
Implant Delivery and Targeted Therapy Instruments
One of the most demanding parts of developing surgical devices concerns implants and targeted therapies. These types of tools typically combine mechanical precision, biocompatible materials, controlled delivery systems, and minimally invasive access.
At HaA PD, we design implant delivery jigs, targeted‑therapy applicators, seed‑dispensers, and specialty instrumentation. Work here involves paying close attention to deployment mechanisms, anchoring, imaging feedback, sterilization, integration into surgical practice, and regulatory classification. The result is equipment that makes safe, effective, and reliable delivery of therapy possible, whether in orthopaedics, oncology, or cardiovascular applications.
Representative Surgical Devices
The following are real examples of medical-device projects that we have helped design, develop, and commercialize. Each is a case study demonstrating our expertise, innovation, and ability to bring challenging devices to market.
Tissue Ablation Device
The AngioDynamics' Solero MTA System is a device we helped optimize for a future-generation tissue ablation platform. For the case study, HaA PD addressed problems of catheter design, material selection, cost profile, and device reliability. We replaced some welded housing parts with snap-fit assemblies, simplified the complexity of component integration, and made prototyping and testing easier to bring an improved ablation system to market.
Radiation / Dosimetry / Oncology Tools
We partnered in the radiation‑therapy industry and helped develop Radiadyne’s Radiation Dose Monitoring that measures radiation doses in real time using a reusable catheter interface and sensor. This project demonstrated our ability to produce devices for monitoring and maintaining radiation therapies in sophisticated clinical environments.
Handheld / Mechanically Driven Devices
We specialize in designing surgical instrument precision mechanisms. For Symmetry's Steerable Drill Guide, we created a one-time precision mechanism with a ratcheting lever and a spring-loaded handle, both made of plastic pieces. This study describes how we developed a compact, robust disposable tool for high-volume surgery applications.
Optical / Illumination Integration
The Symmetry Cobra Lighted Retractor was designed for acetabular/hip surgery. We embedded LED illumination into a surgical retractor in the device, taking into account ergonomics, sterilization compatibility, battery mechanics, and light distribution to improve surgical visibility in tight anatomy.
Other Instrumentation & Systems
One of our medical device systems concerned fluidic systems. We worked with Smith & Nephew on their CDS (Disc Repair / Delivery) System, where fluid delivery and monitoring are controlled automatically for spinal disc repair. Our experts demonstrated their expertise in integrating fluidics, control, and disposability for surgical instruments.
