The difficulty of operating hernias in the abdominal cavity is not only to remove them. It is important to accurately measure, cut out and install a mesh prosthesis on the hernia ring of exactly the size that a particular patient needs. If it is larger than necessary, the patient will at least experience discomfort. If it is less, a hernia recurrence or mesh displacement is possible.

Russian surgeons often are forced to resort to artisanal methods for measuring of hernia sizes. Now a special ruler will be inserted into the abdominal cavity through the trocar using a laparoscopic instrument.

Analogues of the device are already used in medical practice abroad. In Russia, there were no such developments until that moment.
