We live in exciting times. Robotic assisted surgery pushes the boundaries of minimal invasive surgery beyond the limits of laparoscopic surgery. Surgeons manipulate various instruments guided by tiny video cameras attached to the tip of endoscopes and laparoscopes or via x-ray imaging systems in trans-catheter approaches. Miniaturization of surgical instruments, delivery systems and imaging devices plays a crucial role in the development of all of these innovative MIS interventions.

STI is an expert manufacturer of miniature metal components with ample experience in medical device manufacturing of specialized surgical tools such as: rigid and flexible endoscopic tools, laparoscopic suturing devices, arthroscopic reaming devices, probing instruments, scalpels, graspers, hooks, cannulae, needles, guidewires, etc.

Endoscopic surgical tools

Modern medicine uses endoscopes to diagnose a wide variety of medical conditions and in some cases insert instruments through or in conjunction with the endoscope to treat them. Endoscopic procedures apply to hollow organs and cavities, such as: the gastrointestinal tract, urinary tract, respiratory tract, reproductive system, the ear canal, and more. Depending on the medical application, endoscopic surgical tools can be machined to meet exact directional, flexibility and functional specifications.

STI uses its laser cutting technology to machine both the specialized surgical instruments (effectors) and the metal components that determine directional flexibility and torsional transmission of the endoscopic tube. When required, STI applies laser seam welding for attaching surgical effectors to the tip of endoscopic tubes thereby achieving hermetic sealing and minimal profile of the surgical tool.

Arthroscopic surgical instruments

Arthroscopic surgeries are minimally invasive procedures for examining and treating the interior part of joints, including the knee, shoulder, wrist and spine. Arthroscopic interventions treat different orthopedic conditions from cartilage problems to ACL reconstruction.

STI uses laser tube cutting technology to machine intricate vertebra designs from metal tubes. Vertebra design provides flexibility and enables a reaming tool, for example, to deliver torque to the drill bit while maintaining the anatomical positioning of the device.

Laparoscopic surgery

Laparoscopic surgeries are minimally invasive surgeries performed through small keyhole incisions in the abdomen known as ports.

STI manufactures metal parts and provides clean room services for various products used in laparoscopic surgery procedures, for example: needles and mechanical components used in a port closure suturing device.

Guidewires for trans-catheter interventions

Guidewires are thin metal tubes that give catheter-based delivery systems their stiffness and flexibility which enable precise steering through tortuous vasculature. Stiffness helps to push the catheter forward and resist kink build-up, while flexibility is crucial for precisely navigating the catheter through complex vascular structures without damaging or perforating their walls.

Catheter-based systems are used for stent implantation, diagnostic procedures, rotational treatment procedures, drug eluting balloon treatments, trans-catheter implantation of heart valves, and more. The specific application determines the catheter and corresponding guidewire specifications.

Laser cutting enables selective cutting patterns which determine directional flexibility and torsional transmission. Companies using spiral designs for their catheter-based systems and wishing to improve the controlled directional flexibility of their product are encouraged to contact us regarding selective laser cutting alternatives.

Robotic assisted surgery

In robotic assisted surgery the surgeon manipulates complex systems that integrate ultra-precise surgical instruments with moving mechanical mechanisms and advanced imaging capabilities. Since the surgeon is no longer hampered by the physical limitations of traditional surgery, newer and more efficient surgical techniques are developed minimizing the complications associated with highly-invasive operations.

STI manufactures both specialized surgical instruments (scalpels, graspers, hooks, probes, cannulae, needles) and metal components used in miniature mechanical mechanisms of robotic systems (cog wheels, bars, connectors, joints, safety catches).

Aesthetic plastic surgery

Body contouring constitutes a prominent objective for aesthetic plastic surgery. Radio frequency assisted liposuction (RFAL) is a promising technology that offers nonexcisional body contouring.

STI provides micro welding and clean room product assembly services for assembling complete products composed of surgical instruments, mechanical parts, plastic parts, and electrical components.
