Ergonomi, temel olarak insanın makineye değil makinenin insana uyumunu amaç
edinir. Geleneksel diseksiyon makasları tek bir düzlemde olup, sap ve gövde
bölümlerinde herhangi bir eğim bulunmaz. Bunun sonucunda makası kullanan kişi
sürekli olarak bileğini bükmesine bağlı olarak ağrı ve strese maruz kalır. Standart
makaslarda el nadiren nötr pozisyona gelir. Diseksiyonda dokular kat kat
birbirinden ayrılarak incelenir. Dokuların birbirinden ayrılma işlemi diseksiyon
makasları, oluklu sonda ve bisturi ile yapılır. Ergonomik diseksiyon makasının
tasarımının temel amacı, sap kısmı ve kulplarının insan anatomisine uygun
ergonomik yapıda olmasıdır. Makasın sap bölümde; kulplar ve kulp sapları tamamen
parmak ergonomisine uygun hale getirilmiştir. Ayrıca ergonominin temeli olan aletin
bükülmesi gerekliliği olarak sap bölümü eli nötr pozisyonda kalabilecek şekilde
değiştirilmiştir. Makasın, kulpların bulunduğu sap bölümünde parmaklarla, el bileği
ile ve makas-zeminle olan ilişkileri tasarımda temeli oluşturmuştur. Diseksiyonun
sadece makasla yapılmadığı ve kullanılan diğer aletlerinde makasa nasıl adapte
edileceği de düşünülmüştür. Çalışmada bahsedilen tasarım patent almış ve
tescillenmiştir. Makas ve oluklu sonda aynı malzemede olması kullanıcıya diseksiyon
sırasında oldukça rahatlık sağlayacaktır.

ERGONOMIC DISSECTION SCISSORS

Öz

Ergonomics essentially aims to adapt the machine to the human, not the human to
the machine. Conventional dissecting shears lie in a single plane, and there is no bevel
on the handle and body parts. Consequently, the person using the scissors is subjected
to pain and stress due to the constant bending of the wrist. With normal scissors, the
hand rarely comes to a neutral position. Dissection involves separating and
examining tissues in layers. Tissues are separated using dissecting scissors, a
corrugated probe, and a scalpel. The purpose of the design of the ergonomic
dissecting scissors is that the handle and grips have an ergonomic structure suitable
for the anatomy. In the handle area of the scissors, the grips and handles have been
fully adapted to finger ergonomics. Moreover, due to the need to bend the tool, which
is the basis of ergonomics, the handle part was modified to allow the hand to remain
in the neutral position. The relationships of the scissors to the fingers, wrist and base
of the scissors are the basis for the design of the handle part, where the handles are
located. It is also considered that the dissection is not performed only with scissors
and how it can be adapted to the scissors in other instruments used. The design
mentioned in the study has been patented and registered. The fact that the scissors
and the slotted probe are made of the same material provides the user with a high
level of comfort during dissection.
