| Popis: | In order to reduce the time of wound healing of the operated animals and the prevention of complications, we have developed the device of the wound notched hook form by increasing its non-invasive and handling, as well as the retractor for moving apart organs in the abdominal cavity to facilitate the surgical approach, sufficient visibility and control designated and recorded organs by it during surgery. Wound notched hook consists of framing handle with a longitudinal through hole connected to the retaining ring, while on the other side of the fixation ring is formed with the rod with operating element consisting of bent tines. Unlike the commonly used wound notched hook its free ends of the tines are made with drop-shaped thickening for their non-invasive reliance on soft tissue. Application of the developed wound hook notched allows you to: achieve fast and safe placing of the free end tines into the operating cavity as well as the smooth and safe removal of wound hooks notched outside the operating cavity or wound; avoid undue injury tissue of the operated animal. Upgraded retractor comprises a carcass handle connected to the retaining ring, while on the other side of the fixation ring formed conically widening plate bent at right angles and forming the operating element in the form of restrictive platforms. Unlike the conventional retractor restrictive site are made through identical longitudinal rectangular openings arranged parallel to each other and to the longitudinal axis of the retractor for moving apart organs. Developed retractor allows you to: reduce the overlapping area of the continuous operating member retractor in the side aperture of the abdomen; eliminate long clamping organs between the retractor and lateral aperture of the abdomen; reduce the time for the operation; facilitate ligation; reduce the weight of the retractor for moving apart organs; improve the usability of the tool. Together, these tools significantly improve performance with auxiliary surgical instruments and improves the safety of working with them. |
