Classification according to their function 

They are classified into instruments for dieresis or cutting, separation, hemostasis, apprehension, synthesis instruments, drainage. 

Dieresis or cutting instruments: for tissue sectioning. They can be classified into blunt umlaut and acute umlaut. To cut, separate or excise tissue and to cut materials, these instruments require careful handling when handling them to avoid accidents due to their sharp and sharp points. These include: 

  1. a) Scalpel handles: a single instrument body, they can be long, short, straight, and curved; we find them in numbers of 3, 4, 7.

Scalpel blades 20, 21, 22 are large to accommodate number 4 long or short handles. 
  2. b) Scissors: cutting elements or diaresis that is used to cut, remove tissues. Among these, we have mayo scissors for cutting materials and curved or straight Metzenbaum scissors for fabrics. We also find plenty of scissors, torex scissors or hysterectomy scissors, dura mater scissors, common scissors. 
  3. c) Electro scalpel: element at its tip an electrode which performs the function, either cutting or hemostasis; The cable is connected to the electro-cautery equipment and to make contact it needs two poles, one that is the electrode and the other that is the conductive plate that is placed on the patient, which is also connected to the equipment through its cable. 
  4. d) Bipolar: it is an element used to perform hemostasis and cut in delicate and small tissues. It is used in neurosurgery, otorhinolaryngology, and plastic General Surgery Instruments
  5. e) other elements such as gouges, shears, curettes, chisels, osteotomes, electric or manual craniotomes, electric or manual sternotomy can be considered cutting. f) Cutting, specialized: electric or manual saws, electric or manual drills.

-Straight and curved mosquito forceps -Straight and curved Kelly forceps -Straight and curved Kelly Adson forceps -Straight and curved Rochester forceps -Electro scalpel 

❍ Synthetic instruments: it is the instruments used to suture tissues, face, or reestablish their continuity; it consists of a set of elements or instruments such as: 

-Needle holder (specific) -May Hagar scissors-Potts scissors or hard stem -Creels forceps 

-Metzenbaum Scissors-Dissection forceps with and without claws -Sutures of different gauges -Widows needles
