Talking about scissors, forceps and scissors can be enough to frighten some people. Surgical instruments in the past were more raw and backward than they are today, but still impressive. Although the modern versions of these tools are not identical to those of the past centuries, most are simply more advanced versions.

1-Trokar

The trocar is still a widely used surgical tool. In its simple form, the traditional trocars consist of a handle and a shawl, which is a perforator, where three sharp edges come to a point. The trocar blades slide through an outer sheath or cannula. Historically, the car was used to reduce abdominal fatness. This procedure, known as aspiration, is now used in embalming and emergency situations, especially in humans and in homes. Trops are now commonly used in laparoscopic surgeries (abdominal cavity examination procedure) where tools such as laparoscopes can be passed through the cannula.

2-Gorget

Gorget, historically, is an instrument used to extract stones from the stomach. It is concave and conical for the "beak" at the end opposite the bar. The old gorgets were blunt, but later a cut edge was added on the sides of the conical tip (or in some cases on both sides) in designs. Gaga acted as a guided scroll down a groove on an instrument known as the staff under the gorget. The gorgetin cutting edge was then used to create an opening in the waist. After the operation has been performed and the stone has been placed, the surgeon can then be shifted to the waist to recognize and remove a pair of forceps and stones along the concave side of the gorget. Unfortunately, it was not a job and it was not a rare event to cause unnecessary cuts to the rectum or prostate gland.19 Century,

3-Trepan ve Trephine

Trepan was a small tubular saw in the form of a screw, operated as a rubber in which a handle was used to rotate the teeth of the saw. Its main use is in the construction of a skull channel where another instrument can be placed to remove bone fragments that hit the brain following traumatic injury. The procedure, known as trepanning, is thought to relieve intracranial compression by allowing effusion blood to escape. The Trepan was successfully accomplished by a crossbar and a handrail; which used a center-pin to stabilize the saw for cutting first into a circular threaded skull. Later, as the saw blade was pressed deeper, the pin was removed to prevent it from penetrating the dura mater material. The refin is no longer used in western medicine.

4. Eye Spekulum

In the 18th century, the speculum school, an instrument that reached the height of popularity, consisted of a cleft and a claw-like ring attached to a handle holding the sliding knob. The ring is placed so that the eyelids can be locked in a suitable area with the position of the knob on the cord so that the eyelids are pushed towards the eye.
The speculum school was used to fix on-site for various procedures. However, it was a painful tool, because he put a lot of pressure on his pupils. And some doctors discover that they can easily keep the eyelid out with their fingers. Speculum school fell down from use in the 19th century.

5- Amputation Knife

Surgeons have experimented with amputation knives in all shapes and sizes for centuries, but perhaps the most recognizable shape was the sickle that emerged in the 16th century. The instrument is designed to facilitate the cutting of a limb in a single scan, with some surgeons using a knife with a convex cutter edge and a blade with a concave cutter edge. Some model curved amputation blades were double-edged and provided flexibility as the case required. However, generally more straight blades were started to be preferred in general.

6- Prob-Razor

The probing machine looked like a sharp rib with a twist. It was used for a situation known as torticollis and neck pain that was held in a subdued or twisted position. In some patients, contraction of the necked sternomastoid muscle is caused, in which case the 18th century surgeons resorted to cutting the muscles. They did this by cutting a little from the clavicle and passing it through the underside of the narrowing cradle, then the muscles around the cradle were cleaned and cut. Today, this surgical procedure has been shifted in favor of a much simpler procedure in which the tendon of the muscle is cut instead of the Probe-Razor.
