Disclosure of Invention
The invention aims to provide an artificial alar cartilage implant for a patient with nasal alar cartilage malformation or defect.
In order to achieve the above object of the present invention, the present invention provides an artificial nasal ala cartilage implant for correcting a nasal ala cartilage malformation or defect, the artificial nasal ala cartilage implant comprising a trimmable nasal ala cartilage sheet and a trimmable nasal septal cartilage sheet for supporting a nasal height at a middle-lower portion of a bridge of a nose; wherein, the nasal greater alar cartilage sheet body also comprises the nasal greater alar cartilage lateral foot which mainly plays a role of supporting a nasal alar, the nasal greater alar cartilage fornix part which mainly plays a role of supporting a nasal tip, and the nasal greater alar cartilage medial foot which mainly plays a role of prolonging a nasal columella; the nasal alar cartilage sheet body is connected to the nasal septum cartilage sheet body, or the nasal alar cartilage sheet body and the nasal septum cartilage sheet body are integrally formed.
In the artificial nasal alar cartilage implant of the present invention, the nasal alar cartilage vault mainly supporting the nasal apex is located at the turning point between the trimmable nasal alar cartilage sheet and the trimmable nasal septal cartilage sheet, and is a protrusion, which may be a regular circular arc protrusion, an irregular circular arc protrusion, or a protrusion of other shapes. The alar nasal cartilage sheet body and the septal nasal cartilage sheet body are required to be trimmable, because different patients have different nasal shapes such as nostrils and nasal tips, even if the same patient is treated by the same patient, doctors can perform different adjustments under different conditions, so that for the nasal alar nasal cartilage sheet body and the septal cartilage sheet body, the trimming by the doctors can be facilitated, the smooth operation can be facilitated, and the satisfactory postoperative effect of the patients can be obtained.
For the artificial alar cartilage implant of the present invention, it is preferable that the alar cartilage sheet and the septal cartilage sheet are integrally formed in most cases, but this does not mean that the present invention excludes other attachment means of the alar cartilage sheet to the septal cartilage sheet. Any type of connection permitted on the medical material is possible, such as adhesive bonding, crimping, fusion bonding, etc.
The artificial nasal greater alar cartilage implant of the invention can be of a single structure or a double structure. The single structure means that the artificial nasal alar cartilage implant only comprises a left membrane or only comprises a right membrane, wherein the left membrane comprises a left nasal alar cartilage sheet body and a nasal septum cartilage sheet body, and the right membrane comprises a right nasal alar cartilage sheet body and a nasal septum cartilage sheet body. The single construct is suitable for correcting one side (left or right) of a nasal ala cartilage deformity or defect, while the double construct includes both left and right membranes suitable for correcting a bilateral nasal ala cartilage deformity or defect.
In one embodiment of the invention, the artificial nasal greater ala cartilage implant comprises both a left membrane and a right membrane. The left and right film sheets can be connected by an integral forming process or can be bonded, and the adhesive can be a silicon rubber adhesive or other high polymer materials meeting medical standards. If an adhesive is used, the adhesive area usually occupies only a portion, or even a small portion, of the cartilaginous disc of the nasal septum. In such an artificial nasal greater alar cartilage implant, a gap is formed between the septal cartilage sheet body of the left iris and the septal cartilage sheet body of the right iris at a position of the non-bonded portion. The adhesive must meet medical standards and not release harmful components after implantation in the body.
In another embodiment of the present invention, in the case where the artificial nasal greater alar cartilage implant includes both the left and right diaphragms, the left nasal greater alar cartilage sheet, the septal cartilage sheet, and the right nasal greater alar cartilage sheet are integrally formed, because in this case, there is no practical significance in distinguishing the septal cartilage sheet of the left diaphragm from the septal cartilage sheet of the right diaphragm, and both of them may be combined into one. In this case, of course, one or more grooves are provided in the nasal septal cartilage sheet to save material and facilitate trimming by the physician.
Preferably, in the artificial nasal pterocardial implant of the present invention, one or more reinforcing ribs are further included on the nasal pterocardial plate body, and the position of the reinforcing ribs is preferably the back of the nasal pterocardial plate body. Set up the purpose of strengthening rib, can improve the hardness of the big wing cartilage lamellar body of nose on the one hand, on the other hand can also increase the area of contact with musculature after implanting for the implant is more firm.
Preferably, in the artificial alar cartilage implant of the present invention, the septal cartilage sheet further includes on the septal cartilage sheet medial feet of the nasal septum that mainly function to prop up or maintain the height of the nasal tip.
Preferably, in the artificial nasal pterygoid cartilage implant of the present invention, the nasal pterygoid cartilage sheet and/or the nasal septum cartilage sheet further comprises one or more through holes. The purpose of the arrangement is to ensure that muscle tissues grow in the through holes after the nasal greater alar cartilage is implanted into a human body, so that the nasal greater alar cartilage is firmly fixed on the nose of the human body.
In the invention, the selection of the material for preparing the artificial nasal pterocardial cartilage implant is also important, the material is compatible with the human body, does not generate strong rejection reaction, and has proper hardness, and the excessively hard material is easy to generate higher brightness at the implanted part to destroy the aesthetic feeling or is unnatural, and the excessively soft material is difficult to play a corresponding supporting role. Preferably, according to the state of the art at present, the artificial nasal greater pterygoid cartilage implant is made of silicone rubber.
The artificial nasal greater alar cartilage implant can repair nasal alar cartilage defect or dysplasia, and achieve the novel nasal prosthesis which modifies the nasal alar form of the nostril and enables the postoperative effect to be more real and natural.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
