Kelly forceps (also known as Mosquito or Rochester forceps) are a type of
hemostat usually made of stainless steel. They resemble a pair of scissors with
the blade replaced by a blunted grip. They also feature a locking mechanism to
allow them to act as clamps. Kelly hemostats are distinguished from the crile
variety, in part, by their cross-hatched grip pattern, as opposed to a simple
system of grooves. They may be either curved or straight. In
surgery, they may be used for holding off blood vessels or tissues, as general
purpose clamps, or for assorted other purposes. The name comes from its original
A Brief History of Surgical Instruments
instruments have been manufactured since the dawn of pre-history. Rough
trephines for performing round craniotomies were discovered in neolithic sites
in many places. It is believed that they were used by shamans to release evil
spirits and alleviate headaches and head traumas caused by war-inflicted wounds.
Surgeons and physicians in India used sophisticated surgical instruments
since ancient times. Sushruta (circa 500 BC) was probably the most important
surgeon in ancient history, often known as the "father of surgery". In his text
Sushruta Samhita he described over 120 surgical instruments, 300 surgical
procedures and classified human surgery in 8 categories.
In Antiquity, surgeons and physicians in Greece and Rome developed many
ingenious instruments manufactured from bronze, iron and silver, such as
scalpels, lancets, curettes, tweezers, speculae, trephines, forceps, probes,
dilators, tubes, surgical knifes, etc. They are still very well preserved in
several medical museums around the world. Most of these instruments continued to
be used in Medieval times, albeit with a better manufacturing technique.
In the Renaissance and post-Renaissance era, new instruments were again
invented and designed, in order to accompany the increased audacity of surgeons.
Amputation sets originated in this period, due to the increased severity of
war-inflicted wounds by shot, grapnel and cannon.
However, it was only with the discovery of anesthesia and surgical asepsis
that new surgical instruments were invented to allow the penetration of the
inner sanctum, or the previously forbidden body cavities, namely the skull,
the thorax and the abdomen. A veritable explosion of new tools occurred with the
hundreds of new surgical procedures which were developed in the 19th century and
first decades of the 20th century. New materiais, such as stainless steel,
chrome, titanium and vanadium were available for the manufacturing of these
instruments. Precision instruments for microsurgery in neurosurgery,
ophthalmology and otology were possible and, in the second half of the 20th
century, energy-based instruments were first developed, such as electrocauteries,
ultrasound and electric scalpels, surgical tools for endoscopic surgery, and
finally, surgical robots
