Disposable Skin Retractor

In medicine, a skin retractor, also known as a skin anastomosis device or "skin stapler," is a medical instrument that uses sterile metal staples to quickly close skin incisions. It primarily replaces traditional needle and suture suturing, significantly shortening surgical time.

Core Structure: Mainly composed of an upper handle, a lower handle, and a staple cartridge assembly (containing the staples). Some models also include a staple pusher and a staple storage box.

Working Principle: Employs a dual-action mode. The first press of the handle exposes the staple feet (loading); the second press fires and bends the staples, "hooking" the two sides of the skin together like a stapler.

Staple Material: Typically uses high-purity titanium or stainless steel staples, for single use only, and sterilized before leaving the factory.

This technology has been commercialized and is manufactured by multiple companies. Its functions include adjustable tension and dynamic tension reduction, making it suitable for various clinical departments such as orthopedics, general surgery, plastic surgery, and obstetrics and gynecology.

Often used in conjunction with it is the skin retractor, a medical instrument used in surgery to retract the skin and superficial soft tissues, exposing the surgical field. It is mostly claw-shaped or hook-shaped and widely used in superficial surgeries (such as thyroid and breast tumor removal) to help surgeons gain clear operating space.

Skin retractors are mainly used for retracting superficial tissues. For deeper surgeries (such as laparotomy and thoracotomy), other types are used:

S-shaped retractors (such as abdominal retractors): Deep arc design, used to retract abdominal or thoracic organs.

Automatic retractors: Equipped with a robotic arm device, maintaining deep exposure for extended periods.

Specialized retractors: Such as models specifically designed for neurosurgery and cardiovascular surgery, with more specialized functions.

In actual surgery, surgeons will select different shapes and sizes of retractors to use based on the incision depth, tissue characteristics, and exposure requirements.
