在现有胸腔镜手术过程中，一般是在患者的胸壁上穿刺孔洞，以便胸腔镜手术所使用的器械进入患者的胸腔内部，然而容易导致胸腔镜手术所使用的器械与患者胸壁上穿刺的孔洞内壁相接触，进而造成划伤患者胸壁上穿刺的孔洞内壁，给患者带来额外损伤，同时由于患者胸壁上穿刺的孔洞内壁对胸腔镜手术所使用的器械的挤压，严重影响手术视野，不利于手术顺利的进行，此外在手术过程中患者胸腔内部的积液不能被及时吸出，过多的积液威胁患者的生命安全，为此，提出一种胸腔镜手术用辅助装置。During the existing thoracoscopic surgery, holes are generally punctured on the chest wall of the patient so that the instruments used in the thoracoscopic surgery can enter the patient's chest cavity. The inner wall of the puncture hole on the patient’s chest wall is in contact with each other, which will cause scratches on the inner wall of the puncture hole on the patient’s chest wall, which will bring additional damage to the patient. It is conducive to the smooth progress of the operation. In addition, the effusion inside the patient's pleural cavity cannot be sucked out in time during the operation, and the excessive effusion threatens the life safety of the patient. Therefore, an auxiliary device for thoracoscopic surgery is proposed.

The effusion is sucked out in time, and the instruments used in thoracoscopic surgery enter the patient's thoracic cavity through the inner tube 4 to treat the diseased tissue in the patient's thoracic cavity, which is conducive to the smooth progress of the operation. The air is discharged through the exhaust pipe 23, and the device can be taken out, and the wound of the patient is then sterilized, sutured and bandaged.
