[0002] Video-assisted thoracoscopic surgery (VATS) uses modern video technology and high-tech surgical instruments and equipment to complete minimally invasive thoracic surgery for complex intrathoracic operations through chest wall trocars or small incisions. It has changed the treatment concept of thoracic diseases, is regarded as one of the major breakthroughs in the thoracic surgery field in the last century, is a representative operation in minimally invasive thoracic surgery, and is also the future development direction of thoracic surgery. During the operation, under the guidance of the video system, the doctor accurately locates and treats the diseased area, and directly removes the tissue to be removed under the display of the video system. VATS has currently been widely used in the surgical treatment of various diseases such as pleural diseases, pulmonary diseases, esophageal diseases, and mediastinal diseases.
[0003] An incision protector is a medical device widely used in surgical operations, and its main functions include retracting the incision, reducing bleeding and oozing of blood from the incision, protecting the incision and preventing it from being contaminated. Incision protectors are also widely used in VATS. The surgical instruments for VATS can enter the patient's thoracic cavity through the channel provided by the incision protector, and the doctor also needs to observe the lesion through the channel provided by the incision protector. This makes it easy for the surgical instruments for VATS to block the view and affect the surgical operation. At the same time, surgical smoke is easily generated during VATS, which also blocks the view. Summary of the Utility Model
