Whether it's wonderful workmanship or whimsy, an excellent finished product is always presented to us. However, we often overlook an important issue. Behind these beautiful scenes, we need to use some tools. Similarly, a perfect operation is of course inseparable from surgical instruments. The patented rhinoplasty instrument invented by Wu combined with years of clinical experience is not only more convenient for doctors to operate, but also more humanized and comfortable. As early as 20 10, three patents obtained national patent certificates and were widely used in clinic. All the beauty seekers who asked Wu for nasal plastic surgery benefited a lot, which not only ensured the success of every operation, but also brought a relatively comfortable feeling of operation to the guests, greatly shortened the operation time and, most importantly, ensured the perfection of the operation effect. It should be said that these tools have certain functions.
1), and obtained the patent certificate of utility model.
Function of this tool: It is an indispensable tool for autologous cartilage nose plastic surgery. Squeeze the cartilage with a cartilage extruder to soften it, and then shape it as needed.
Advantages of Wu's improved cartilage squeezer;
① It can not only deal with the requirements of high shaping, but also deal with cartilage simply.
② Rough interface and smooth interface exist in the groove at the same time, giving doctors more choices.
(3) The operation is simple, the rough interface can crush the cartilage slightly, and the smooth surface can be used after simple treatment.
④ Lightweight and flexible design enhances functionality.
2) alar cartilage fixing plate, and obtained utility model patent certificate.
Function of this tool: alar cartilage is located in the upper part of nasal vestibule. Nasal surgery often requires operations such as peeling and cutting alar cartilage. Because alar cartilage is suspended, it is not easy to fix, and it cannot be accurately located during surgery. After the alar cartilage was fixed correctly with the alar cartilage fixing plate, the operation was accurate and quick.
Introduction of perfect design concept: the shape and performance of spoon are introduced into the design concept of alar cartilage fixing plate. The old fixed plate is stiff and straight, and it lacks affinity to the inner wall of nose during operation, which is not convenient for operation; The new spoon surface is designed to fit the nose wing, making the scalpel easier to operate.
Practice leads to true knowledge: Wu improved alar cartilage fixation plate with 5~7 teeth. The design of the number of teeth on the back has strict technical requirements. According to the data summarized from practical experience, 5 ~ 7 teeth are suitable. The distribution of vertical teeth presents a five-pointed star layout. A tooth at the tip can cling to the inner wall of the alar, making it easier to fix. The four vertical teeth at the back can independently form an operation interface, which is convenient for operation. Non-straight, the number and distribution of vertical teeth are strict, easy to fix and accurate to operate.
3) Nasal septum retractor, and obtain utility model patent certificate.
Function of this tool: Also called rhinoscope, it is an essential medical instrument for nasal septum in otolaryngology clinical examination. It mainly includes a handle and a mouth, which are integrated front and back. The left and right handles are connected together by hinges, and a joint is formed at the hinge joint of the left and right handles.
Disadvantages of old equipment
① Short mouth and small opening face are not conducive to observing the diseased parts in patients' nostrils;
(2) Mouth stricture causes patients too much pain and psychological burden;
③ The distance between the mouth and the joint is short, which makes the patient feel uncomfortable because of the inconvenience of the doctor's operation;
④ The distractor is made of metal, which is in contact with the patient's face, which is not conducive to surgery or examination.
⑤ The joint is immobile, and its expansion can only be controlled by the doctor's experience and hand movements. Too much support will cause pain to patients, and too little support is not conducive to doctors to observe the nostrils for surgery.
Wu improved the nasal septum distractor: it overcame the discomfort caused by its short mouth. After the mouth is elongated, the patient's nostrils can be observed more clearly and further; Moreover, the flat circular arc design increases the contact surface between the distractor and the nostril, which is more comfortable and convenient for doctors to operate.
