The present invention relates to a nasal implant that is inserted under the skin of the nose and adheres to the nasal bone, hump, and nasal cartilage to improve the shape and function of the nose. Specifically, the nasal implant, which is inserted under the skin of the nose and used in rhinoplasty, comprises a nasal bone implant formed to be in contact with the nasal bone and formed with a curved surface, a cartilage implant extending from the nasal bone implant and formed to be in contact with the cartilage, and a hump implant connecting the cartilage implant and the nasal bone implant, which is formed to be inwardly recessed to be in contact with the hump.

A nose prosthesis (50) for insertion into the nose bridge of a human body comprises: an insertion tip (51) having a tip; the diameter of the conical main body part (52) is gradually increased backwards; a rear end portion (53) provided at the rear of the cone portion (52); and a position adjusting portion (54) extending from a rear end portion (53) of the tapered body portion (52) to adjust a position of the nose prosthesis (50), in which the rear end portion (53) is formed in a hemispherical shape or a tapered shape, and a groove (54a) is formed circumferentially at a connection portion of the rear end portion (53) and the position adjusting portion (54).

This application discloses a nasal implant processing apparatus, relating to the field of nasal implant processing. It includes a base, a support ring, a first rotating ring, and a second rotating ring. The support ring is fixedly mounted on the base. The first rotating ring is coaxially rotatably mounted on the support ring. Three clamping components are slidably arranged at intervals along the circumference of the first rotating ring, with their close-to-each ends clamping and limiting the nasal implant. The second rotating ring is coaxially rotatably mounted on the support ring, and a support component is mounted on the second rotating ring. The support end of the support component abuts and supports the opposite side of the nasal implant to be processed. This application uses three clamping components to clamp and limit the nasal implant, combined with the support component to abut and support the nasal implant, making it less prone to shaking during processing and carving, thus improving the processing accuracy of the nasal implant. By rotating the first rotating ring, the nasal implant can be rotated and adjusted without releasing the clamping and limiting state, thereby improving the processing efficiency of the nasal implant.

The application relates to an intelligent controllable super-deformation nose prosthesis, belonging to the field of plastic surgery medical instruments, which combines an inner concave hollow omega-shaped structure frame main body shell layer, a Janus interface outer coating and intelligent response materials to construct an anatomic-structure-function integrated nose prosthesis, performs micropore design and hydroxyapatite coating on the ventral side of the nose prosthesis to form a high-adhesion and high-stability nose prosthesis structure, performs smooth design and spermidine coating on the dorsal side of the nose prosthesis to inhibit envelope formation and avoid envelope constraint, combines the inner concave hollow omega-shaped structure design to realize super-orientation deformation performance, and the application of the intelligent response materials can realize non-invasive deformation adjustment through a temperature signal during or after surgery to meet the clinical requirements of intraoperative and postoperative fine adjustment. The nose prosthesis can be applied to plastic surgery, postoperative modification, repair and reconstruction scenes to meet higher-level medical and aesthetic requirements.

The utility model discloses a kind of guide for preventing prosthesis skew, it is related to orthopedic surgery auxiliary instrument technical field.The guide includes handle, handle one end two sides are puncture structure, puncture structure is equipped with guide through-hole, for the through of guide wire.Setting.The total length of guide is 18cm, the diameter range of guide wire that guide through-hole can pass is 0.5mm-1mm.When using, guide wire is connected prosthesis and is set to guide through-hole, guide is inserted into nasal cavity from incision, pulls guide wire and makes prosthesis move to predetermined position along guide direction, avoids prosthesis skew, finally cuts off guide wire, withdraws guide, and guide wire and prosthesis are left in nasal cavity, complete surgery.The utility model improves the precision and stability of nasal prosthesis implant by the cooperation of guide and guide wire, reduces the risk of surgery, and is suitable for rhinoplasty.

The present application relates to the field of biological medical materials and preparation technology, and specifically provides a 3D printing nose prosthesis based on a preset folding line sheet origami structure, the nose prosthesis is made of a biocompatible material, is integrally formed in a foldable sheet form through a 3D printing technology, and is provided with a plurality of preset folding line origami structures on the nose prosthesis, the nose prosthesis can be implanted into the body after being folded along the preset folding lines, and is unfolded along the preset folding lines after being implanted, so as to form a three-dimensional nose support structure; a preparation method of the 3D printing nose prosthesis based on the preset folding line sheet origami structure specifically includes five steps. Through the sheet structure and the preset folding line design, the present application significantly reduces the manufacturing and operation difficulty; the implantation can be completed through a small incision, so that the surgical incision and the infection probability are reduced; the folding and unfolding paths are controllable, and the unfolded form is stable; the material and the printing process selection range are wide, and the adaptability is strong; and the present application is beneficial to the realization of personalized customization and clinical popularization and application.

The utility model discloses a nose prosthesis capable of preventing displacement, which comprises a nose bridge part, a nasal columella and a positioning support leg, and a nose tip part is arranged at one end of the nose bridge part; the nasal columella is positioned at the nose tip part and is bent towards the inner side so as to form a preset angle with the nose bridge part; the positioning support leg is connected to one end, far away from the nose bridge part, of the nasal columella, and the positioning support leg is vertically connected with the nasal columella to form a T-shaped structure. According to the nose prosthesis capable of preventing displacement, the vertical positioning supporting leg is arranged at one end, far away from the nose bridge part, of the columella nasi, the positioning supporting leg and the columella nasi form the T-shaped structure, and the T-shaped structure is embedded into tissues, so that the contact area between the prosthesis and the surrounding tissues is remarkably increased, and the stability of the prosthesis is greatly improved; according to the nose prosthesis, the prosthesis is effectively prevented from moving in all directions, especially moving in the up-down direction and the front-back direction, so that the nose prosthesis can keep a long-acting attractive shape, and the satisfaction degree of a user is improved.
