Percussion hammer (Plessor), Plexor (Plexor)

A percussion hammer, also known as a Plessor, and a plexor, or Plexor, is a medical instrument used to examine nerve reflexes and perform percussion. These instruments have been used in medical practice for over a century.

Percussion hammers were developed in the 19th century and became an integral part of medical practice. They consist of a handle and a metal head, which can be flat or round. The instrument is used to stimulate nerve endings by pressing on various points on the patient's body. This allows medical professionals to assess the nervous system's response to various stimuli and determine the presence of pathologies.

Percussion hammers are also used for percussion, which is a method of studying the condition of internal organs, based on the study of sounds that are created by lightly tapping the patient’s body. In this case, the instrument is used to create light shocks on the patient's body, which allow the healthcare professional to determine the boundaries of internal organs and the presence of fluid or air in certain areas of the body.

Percussion hammers and plexors come in a variety of shapes and sizes to suit the varying needs of medical practices. Some hammers have adjustable impact force, allowing the healthcare professional to control the amount of nerve stimulation.

Although more modern methods exist for studying nerve reflexes and percussion, percussion hammers and plexors are still widely used in medical practice. They are an important part of the diagnostic arsenal of medical professionals and help ensure accurate diagnosis and treatment of patients.



A percussion hammer (plexor) is a small hammer that is used to study nerve reflexes and is also used for percussion.

A plexor is a metal rod about 15 cm long, with a handle attached at one end and a hammer weighing 5-10 grams at the other.

Using a plexor, the doctor examines tendon and periosteal reflexes, and also uses it for percussion - a method of physical examination based on tapping areas of the body with a hammer and listening to the sounds that arise.

Percussion and examination of reflexes using a plexor allows the doctor to obtain important information about the condition of the patient’s internal organs and nervous system.



In medical practice, the device examines the state of the human nervous system and is carried out by influencing it. A percussion hammer is a specialized instrument, which in medicine is called a plexor. The instrument is intended for both research and treatment of the patient. Using a percussion hammer, the condition of the nerve fibers and muscle corset of a person is assessed.
