Andrological surgeryCircumcisionPediatric surgeryPhimosisPlastic surgery


An instrument adapted to perform circumcisions in a mechanical way, with or without the aid of various equipment or electrical supply. The device allows an improvement of the tools previously used to perform circumcision. It is characterized by perfect symmetry of the cut, rapidity in execution, less bleeding, increased prevalence without needing to use stitches.

Technical features

Mechanism composed of: a suitably shaped plastic pistol, a pistol trigger handle, a fixed stem connected to the central pin of the pistol, which holds a protective bell for the glans and which also acts as a blanking template, a blanking template bell integral with the stem, two concentric medical steel cannulas, one of which fixed internal integral with the bell-shaped blanking template and one external mobile, two blades in titanium or biomedical steel, suitably shaped and connected to the external cannula, a wheel for rotation of the gun around its longitudinal axis and finally an internal mechanism that transforms the angular motion of the trigger into longitudinal motion of the cannula. The two blades are shaped so as to cut the excess skin of the foreskin in a perfectly circular manner and to compress the two flaps of skin, internal and external of the foreskin, in a specific area. A circumferential cut is obtained, a cut in the contact area of ​​the two blades and a cauterization of the compressed tissues. The invention stems from the need to practice circumcision, a medical practice that often has religious origins and motivations, at the hospital level and not in safety and with greater precision.

Possible Applications

  • Urology for phimosis;
  • Pediatric surgery for phimosis;
  • Ritual surgery;
  • Andrology in case of penile malformations.


  • Minimally invasive surgery with lower risk of bleeding;
  • Less need for suturing;
  • Easy to use reduction of intervention times (about 10 minutes);
  • Symmetry of the cut;
  • Safe protection of the glands;
  • Hygienic procedure for the interchangeability of disposable components in contact with the patient’s blood.
