A surgical device is any instrument, apparatus, implement, or machine used to perform surgical procedures or to facilitate diagnosis and treatment in a clinical setting. Devices may cut, dissect, grasp, retract, deploy implants, deliver energy, or enhance visualization and access. They can be used in open surgery or minimally invasive approaches and are designed to be sterilized between uses.

Common categories include cutting and dissecting tools such as scalpel blades and scissors; grasping and holding instruments like forceps and clamps; retractors and exposure devices including surgical retractors and specula; access and visualization tools such as trocars, dilators, and endoscopes; energy-based devices such as electrosurgical pencils, ultrasonic or harmonic scalpels, and lasers; suturing and stapling devices including needle holders, staplers, and ligating clips; and implant delivery systems such as bone screws, vascular graft delivery, and mesh implants.

Advances in surgery emphasize minimally invasive techniques and precision. Robotic-assisted systems provide articulated instruments with motion scaling and tremor reduction, while improved imaging, navigation, and fluorescence-guided guidance aid accuracy. Disposable single-use instruments reduce cross-contamination, whereas reusable tools require sterilization and maintenance protocols. Device design emphasizes ergonomics, sterilization compatibility, and biocompatible materials.

Regulatory oversight ensures safety and effectiveness. In many jurisdictions, surgical devices require premarket clearance or approval, quality management systems, and post-market surveillance. Materials commonly used include stainless steel, titanium, and medical-grade polymers. Proper use depends on training, institutional protocols, and adherence to sterilization standards to minimize infection and device-related injuries.
