Description

Technical Field

[0001] The utility model belongs to the technical field of nose augmentation dissection devices, and particularly relates to a nose augmentation dissection device for minimally invasive surgery. Background Technique

[0002] Rhinoplasty refers to a surgery that improves the appearance of the nose by filling the nose with autologous, allogeneic tissues or tissue substitutes to elevate the external nose. There are two surgical methods for rhinoplasty incisions: columella incision and internal nasal incision. Among them, the internal nasal incision is commonly used because the incision is concealed and there is no visible scar on the surface. At the beginning of surgical rhinoplasty, the patient is first under general anesthesia or local anesthesia. Generally, a plastic surgeon first separates the nasal skin from the subcutaneous soft tissue, sutures the incision, and fixes the just-operated nose with tape to promote healing. Depending on the needs of different patients, sometimes autologous cartilage transplantation or simultaneous use of general fillers is adopted to strengthen or change the contour of the nose. The autologous transplanted tissue is usually obtained from the nasal septum, but if there is not enough, it can be obtained from costal cartilage or auricular cartilage. Therefore, higher requirements should be placed on the skills of plastic surgeons. In rhinoplasty surgery, a nasal dissector is an essential surgical instrument for incising and dissecting the mucosa in the nasal cavity to facilitate the placement of a prosthesis and assist in completing the rhinoplasty surgery.

[0003] The publication number of the comparative patent document is: "CN218356318U A dissector for minimally invasive rhinoplasty, including a main body. A round hole is provided on the outer surface of the main body. A telescopic component is sleeved on the outer surface of the main body. Adjusting components are slidably connected to both sides of the main body. A first dissection head and a second dissection head are respectively arranged at both ends of the adjusting component. The telescopic component includes a sliding ring. A first spring is fixedly connected to the inner cavity at the top of the sliding ring. The bottom end of the first spring is fixedly connected to a sliding plate. The dissection head angle of the dissector for minimally invasive rhinoplasty of the utility model can be adjusted and can be appropriately adjusted according to the different angles of nose depression of each person. Therefore, it can adapt to more rhinoplasty surgeries without replacing the dissector, reducing the difficulty of dissection operations; the dissector for minimally invasive rhinoplasty can change the length of the dissector, ensuring that doctors of different heights can use it more conveniently and improving the dissection efficiency."
