Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a tracheal anastomosis device. Background Art

[0002] The purpose of bronchial sleeve lobectomy is to remove the diseased lobe and the affected bronchus, and then anastomose the upper and lower stumps of the bronchus to maximize the patient's lung function and improve the prognosis. Whether it is open chest or thoracoscopic, anastomosis of the upper and lower stumps of the bronchus becomes the most critical and challenging surgical link. Limited by the anatomical position and anatomical structure characteristics of the trachea, the current operation can only use manual silk suture to anastomose the tracheal ends, which is extremely difficult to operate under a single-port thoracoscopic approach, and the quality of suture directly determines the incidence of postoperative complications and prognosis of patients. This type of surgery faces several major difficulties: First, the angle and depth of needle insertion determine whether the trachea is damaged during the suturing process and whether the trachea is narrowed and leaking after the suturing is completed. Because it is extremely dependent on the surgeon's tracheal suturing experience and personal ability, the medical institutions that can carry out this type of surgery are relatively limited, and the incidence of postoperative complications varies greatly among different surgeons. Secondly, the surgeon needs to suture the trachea needle by needle during the operation. The single-port thoracoscopic operation requires many needles to be inserted and the space is limited. The sutures are prone to entanglement and knotting, making it difficult to organize the sutures, which will also affect the suture quality. This shows that tracheal anastomosis is difficult and has a high threshold during bronchial sleeve lobectomy. Summary of the invention
