Compass (Calliper, Caliper)

A compass (eng. calliper, caliper) is a tool that is used to measure the diameters of circles. It consists of two legs connected by a hinge. The distance between the ends of the legs shows the diameter of the object being measured.

The compass is used in various fields:

1. In obstetric practice to measure the size of the pelvis during childbirth. This allows you to assess how well the woman’s pelvis corresponds to the size of the baby’s head and identify possible complications during childbirth.

2. In orthopedics, a special type of compass is used - a calliper splint. This is a leg splint consisting of metal rods attached to a soft ring on the thigh. The rods support the patient's body weight and allow the deformed or paralyzed leg to be unloaded and extended as a component of orthopedic treatment.

3. In technology for measuring the diameters of parts, workpieces, holes and other dimensions with high accuracy. Different types of compasses are used - from simple mechanical to electronic with digital readout.

4. In jewelry and watchmaking for precise measurements of small parts.

Thus, a compass is a universal measuring instrument with a wide range of applications in medicine, technology and other fields. Its design allows you to quickly and accurately determine the size of objects.

A compass (Calliper, Caliper) is a tool that is used to measure the diameters of circles. It is widely used in various fields, including obstetric practice, where it is used to measure the diameter of the pelvis.

One of the most common uses of a compass is its use in obstetric practice. During labor, doctors and midwives use a caliper to measure the diameter of the mother's pelvis. This information helps them determine whether the baby can pass through the birth canal, and if not, a caesarean section may be required.

However, the compass can also be used in other areas of medicine. For example, in orthopedics, a compass can be used to measure the diameter of bones to help doctors select the correct implant size.

In addition, there is also a so-called calliper splint, which is also called a compass. This is an orthopedic device that is used to traction a deformed or paralyzed leg. A leg splint contains metal rods attached to a soft ring in the upper leg that support the body's weight. This allows the patient to keep the leg in the correct position and speeds up the healing process.

In general, compasses are an important tool in various fields, from medicine to construction. It can accurately measure the diameter of circles and is used for a variety of purposes, including diagnosis and treatment.

A compass is a tool for measuring the diameters of a circle. It is used in obstetrics to measure the size of the pelvic circumferences in women, as well as in orthopedic medicine to stretch deformed and paralyzed legs.

In obstetrics, a compass is a mandatory device at all stages of obstetric procedures, starting with
