When a joint is injured, a doctor may need to see the condition of the tissues from the inside rather than assess them only through indirect signs. Arthroscopic examination is used for this purpose. An optical endoscope is inserted into the joint cavity through a small surgical access, and the image is transmitted to a monitor. This allows the specialist to examine intra-articular structures and, if necessary, immediately proceed with a therapeutic procedure.

Diseases of the urinary system cannot always be accurately diagnosed based on test results or ultrasound findings. When a doctor needs to directly assess the condition of the urethra and urinary bladder, an endoscopic examination is performed.

Hysteroscopy is a modern endoscopic method used for the diagnosis and treatment of intrauterine pathology. During the procedure, the physician obtains a direct view of the cervical canal and uterine cavity, assesses the condition of the endometrium, identifies the location of pathological lesions, and, when necessary, performs therapeutic procedures. The quality of the examination depends on the optics, lighting, instrument design, and equipment of the endoscopic system.

<p> Many ENT patients are interested in what an ENT endoscope looks like. When a doctor shows them the device, the first impression can be misleading: externally, it is a thin metal tube with an optical system at the end. The working diameter is small, but the interior contains sophisticated optical components that directly determine image quality. </p> <br>

Laparoscopy and endoscopy are often perceived as two identical methods because in both cases the doctor uses optical equipment and obtains images of internal structures. In practice, however, they are different methods of performing diagnostic and surgical procedures. The main difference is related to access to the organs: during laparoscopy, equipment is inserted through small incisions in the abdominal wall or another area of the body, whereas in conventional endoscopy, the endoscope is introduced through natural openings.

<p> Examination of the nose is rarely limited to what the doctor can see during an external examination. The main changes are located inside the nasal cavity: on the mucous membrane, nasal turbinates, septum, nasal passages, and deeper structures such as the nasopharynx. To assess these structures, an otorhinolaryngologist performs rhinoscopy. </p> <p> <br> </p>

A laparoscope is a metal tube with a diameter of 10 or 5 mm, fitted with a complex lens system and a light guide. Laparoscopes are designed to transmit images from within the human body using lens or rod optics and a rigid outer tube. They are classified as rigid endoscopes.

Pre-sterilization cleaning is the most critical stage in preparing laparoscopic instruments for reuse. During this process, blood, protein residues, tissue fragments, pharmaceutical residues, and detergent residues are completely removed from the instrument surfaces.

Laparoscopic instruments are designed for repeated use; however, their service life and operational safety directly depend on proper reprocessing. Even high-quality instruments can quickly become damaged if cleaning protocols are not followed, inappropriate chemicals are used, or sterilization is performed without considering the manufacturer's recommendations.

Modern urology is actively adopting minimally invasive endoscopic technologies that make it possible to perform complex procedures with high precision. One of the advanced solutions on the market is the “Plazmatic” high-frequency electrosurgical unit by ElePS. This system is specifically designed for use with bipolar electrodes in a liquid medium — NaCl solution — providing safe and effective treatment of urogenital conditions.
