A method for repairing for repairing stenosis in an airway of a patient is disclosed using laryngeal forceps having a measurement scale. The method includes harvesting a cartilage graft from a patient and inserting a laryngoscope into the respiratory tract of the patient. The stenotic region is prepared by removing stenotic tissue to create a recipient site for insertion of the cartilage graft. A width measurement of the recipient site is obtained using the laryngeal forceps. The width measurement is shown on the laryngeal forceps indicating a distance value between the first jaw tip and second jaw tip of the forceps. The measurement scale may include graduated markings or a digital display. A thumbscrew may be included for locking the jaws and handle in a fixed position. The forceps may include triangular jaws with pointers for precise alignment with and measurement of the stenotic region.

The application discloses a combined digital guide plate system for free gingival grafting and belongs to the technical field of stomatology. The combined digital guide plate system for free gingival grafting comprises a base guide plate, a recipient site semi-thick incision indicating guide plate, a recipient site full-thickness incision indicating guide plate, a temporary restoration-soft tissue fixation clamping plate and a donor site indicating guide plate; the base guide plate is used for positioning and fixing the guide plates and the temporary restoration-soft tissue fixation clamping plate of the recipient site. The application covers the recipient site semi-thick incision indicating guide plate, the recipient site full-thickness flap incision indicating guide plate, the temporary restoration-soft tissue fixation clamping plate and the donor site indicating guide plate, and realizes the functional integration of the whole free gingival grafting treatment process in combination with the composite structure design of the base guide plate and the split accessory guide plate. The application can realize accurate positioning, avoid damaging anatomical structures, accurately prepare semi-thick flaps and full-thickness flaps, shorten the tooth loss period of the patient, prevent the rebound of the vestibular groove, and ensure the curative effect of the free gingival grafting.

This invention discloses an autologous bone graft guide assembly and an autologous bone trimming method. The guide assembly includes a bone harvesting guide, a titanium screw guide, a bone grafting guide, a trephine, a drill bit, and titanium screws. Each of the bone harvesting guide, titanium screw guide, and bone grafting guide includes interconnected positioning and operating areas. The operating area of ​​the bone harvesting guide includes a trephine positioning hole. The operating area of ​​the titanium screw guide includes a titanium screw positioning hole, the positioning area of ​​which is the same as that of the bone harvesting guide, and the position of the titanium screw positioning hole corresponds to the center of the trephine positioning hole. The operating area of ​​the bone grafting guide includes a bone graft positioning hole of the same size as the trephine positioning hole. This guide assembly unifies the donor site bone harvesting boundary, pre-drilled hole site, and recipient site bone graft fixation position on the same spatial reference, achieving millimeter-level precise navigation and titanium screw fixation throughout the autologous bone grafting process. It is particularly suitable for "more harvesting, less grafting" clinical scenarios in the oral cavity where bone removal is required in the donor site and bone grafting is required in the recipient site, significantly improving autologous bone utilization and surgical predictability.
