Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a nasal prosthesis implantation device. Background Art

[0002] As people's pursuit of beauty continues to improve, rhinoplasty has become the most popular plastic surgery project, and more and more beauty-conscious people choose rhinoplasty to correct their nose shape. In surgical rhinoplasty, an incision is first made on the columella or the inner side of the nasal cavity, and then the periosteum of the bridge of the nose is separated. After the periosteum and the nasal dorsum fascia are stretched, a prosthesis (such as human tissue, silicone, expanded material, etc.) is implanted under the periosteum to reshape the nose contour, and finally the incision is sutured. During the rhinoplasty process, a clamping tool is generally required to implant the nasal prosthesis into the nasal cavity.

[0003] However, the existing nasal prosthesis implantation equipment still has certain shortcomings when used. The incision for nasal prosthesis implantation surgery is generally selected on the inner side of the columella. After the material is implanted, the incision is sutured. However, due to the small size of the wound, the insufficient field of view inside the wound can easily affect the operation of medical staff, so the wound needs to be retracted to facilitate the medical staff to implant the nasal prosthesis. The existing traction device uses manual traction, which may cause the exposed field of view of the wound to deviate or cause the wound to tear due to improper operation due to different forces. In addition, the existing nasal prosthesis implantation equipment is manually clamped, and medical staff need to always maintain the clamping state during use. The prosthesis is prone to fall off when relaxed, and once the medical staff uses too much force, it may even cause damage to the prosthesis. Utility Model Content
