Description

Special surgical instrument for lung segment of single-hole thoracoscope

Technical Field

The utility model relates to the technical field of surgical instruments, in particular to a surgical instrument special for a lung section of a single-hole thoracoscope.

Background

In the last decade, with the popularization of low-dose spiral CT, the epidemiology and treatment mode of lung tumor have changed greatly, and the number of early-stage lung cancer patients and advanced-stage lung cancer patients is increasing, and the corresponding surgical treatment method for lung cancer is rapidly developed in different layers. The Chinese Society for Clinical Oncology (CSCO) primary lung cancer treatment guideline (2018 edition) shows that lobectomy has long been considered by most thoracic surgeons as the standard surgical procedure for stage I non-small cell lung cancer surgical resection, while recent clinical evidence supports that for peripheral stage I non-small cell lung cancers not exceeding 2cm in diameter, especially pure ground glass nodules, segmental or wedge resection may be the better surgical resection procedure. Churchill et al first reported cases of lung resection for treatment of bronchiectasis in 1939. During the next decades, segmental lung resection was attempted for the treatment of NSCLC. The first use of segmental lung resection by Murakami et al, Japan in the treatment of NSCLC is that segmental lung resection can retain more lung tissue and thus have less effect on the patient's lung function than lobectomy. Lobectomy cannot be tolerated due to cardiopulmonary insufficiency, where a segmental or wedge resection of the lung becomes a surgical option for these patients. A number of retrospective studies suggest: the lung segmental resection is used for treating selective early lung cancer, has similar oncological curative effect with the lung lobe resection, has the advantage of protecting the lung function, and has better oncological curative effect than the wedge resection due to the advantage of the margin width. The ideal lung resection is: ensuring that the tumor margin minimizes resection of the target segment and leaving the lung segment fully functional requires precise lung segment resection. Therefore, in the lung segment operation of the single-hole thoracoscope, a thoracic surgeon urgently needs a special surgical instrument capable of completing the fine operation, and the requirements of the surgical instrument on radian, precision, angle and the like are high.

However, the conventional suture forceps for lung segment surgery has the following problems in the use process: (1) the used surgical instruments are set for the lung lobe resection, when the lung lobe resection is performed, the artery, vein and bronchus of the lung lobe need to be dissociated from the lung tissue or the mediastinal tissue, and then the artery, vein and bronchus are sutured and disconnected by using the linear cutting suturing device, at the moment, the disconnected artery, vein and bronchus are all main passages which are relatively thick, the diameter is about 5mm-10mm, the surgical instruments used at present are thick, the operation is inconvenient, the bending amplitude of the end part of a forceps used for suturing the lung is unreasonable, and the force application and the accurate operation are inconvenient; (2) in order to ensure the normal operation of the operation, the suturing instruments of different types and sizes are used in the operation process, the types are complicated, and the burden is increased on the later-stage disinfection and cleaning. For this reason, a corresponding technical scheme needs to be designed to solve the existing technical problems.
