背景技术Background technique
肺癌发生于支气管黏膜上皮，近50年来肺癌的发病率显著增高，在欧美工业发达国家和我国的一些工业大城市中，肺癌发病率在男性恶性肿瘤中已居首位，在女性发病率也迅速增高，占女性常见恶性肿瘤的第2位或第3位。肺癌成为危害生命健康的一种主要疾病。肺癌的治疗有外科治疗、放射治疗、化学疗法和免疫疗法。外科治疗已被公认为治疗肺癌的首选方法，要依据肺癌临床分期选择治疗方案。根治性切除到目前为止是惟一有可能使肺癌病人获得治愈从而恢复正常生活的治疗手段。术前必须评估病人是否耐受手术。这些检查通常包括：临床物理检查、肺通气功能、血液检查等。对于边缘病人，应采用肺灌注扫描以更准确评估肺功能，或采用耐力试验和冠状动脉造影来评估心脏功能。Lung cancer occurs in the epithelium of the bronchial mucosa. The incidence of lung cancer has increased significantly in the past 50 years. In industrialized countries in Europe and the United States and some large industrial cities in my country, the incidence of lung cancer has ranked first among malignant tumors in men, and the incidence of lung cancer has also rapidly increased in women. Increased, accounting for the second or third of the common malignant tumors in women. Lung cancer has become a major disease that endangers life and health. Treatments for lung cancer include surgery, radiation therapy, chemotherapy, and immunotherapy. Surgical treatment has been recognized as the first choice for the treatment of lung cancer, and the treatment plan should be selected according to the clinical stage of lung cancer. Radical resection is so far the only possible treatment for lung cancer patients to be cured and return to normal life. The patient's tolerance to surgery must be assessed preoperatively. These tests usually include: clinical physical examination, pulmonary ventilation function, blood tests, etc. For borderline patients, lung perfusion scan should be used to more accurately assess lung function, or endurance testing and coronary angiography should be used to assess cardiac function.
肺癌发病率逐年上升，随着检查方法的进步，早期肺癌的诊断率大大提高，国内外已有研究证明：早期肺癌采用大分割立体定向放疗技术可获得和外科手术同样的疗效。目前肺癌大分割立体定向放疗时，相当一部分因肿瘤位置贴近胸壁，放疗后会产生胸壁和肋骨坏死，阻碍了部分肺癌患者立体定向放疗的实施。目前国内外正采用的方法是：在早期肺癌病灶贴近胸壁时，通过限制肿瘤放疗剂量降低肋骨和胸壁损伤发生率，是得放疗疗效受到影响。目前国内外没有此类产品研究。The incidence of lung cancer is increasing year by year. With the improvement of inspection methods, the diagnosis rate of early lung cancer has been greatly improved. Studies at home and abroad have proved that early lung cancer can obtain the same curative effect as surgery with hypofractionated stereotactic radiotherapy. At present, during hypofractionated stereotactic radiotherapy for lung cancer, a considerable part of the tumor is located close to the chest wall, resulting in chest wall and rib necrosis after radiotherapy, which hinders the implementation of stereotactic radiotherapy for some lung cancer patients. At present, the method being adopted at home and abroad is: when the early lung cancer lesion is close to the chest wall, the incidence of rib and chest wall injury is reduced by limiting the dose of tumor radiotherapy, so that the curative effect of radiotherapy is affected. There is no such product research at home and abroad at present.
为解决上述问题，现在提出一种经皮穿刺胸膜腔内留置球囊肺推开器。In order to solve the above problems, a percutaneous puncture and indwelling balloon lung pusher is now proposed in the pleural cavity.

本发明一种经皮穿刺胸膜腔内留置球囊肺推开器，包括球囊，所述球囊内部有可视标记，所述球囊一端设有导丝，所述球囊另一端有导管，所述导管上设有连接头，所述导管上设有滴管，所述滴管上设有压力表，所述压力表上连接盐水袋。The present invention is a percutaneous puncture indwelling balloon lung pusher in the pleural cavity, comprising a balloon, a visible mark inside the balloon, a guide wire at one end of the balloon, and a catheter at the other end of the balloon , the conduit is provided with a connector, the conduit is provided with a dropper, the dropper is provided with a pressure gauge, and the pressure gauge is connected to a saline bag.
进一步的，所述盐水袋保持300mmHg压力。Further, the saline bag maintains a pressure of 300mmHg.
本发明的有益效果是：通过本发明在微创条件下将肺脏与胸壁推离，以避免大剂量放疗时，放射线对胸膜、胸壁肋骨、及神经等软组织的损伤，从而避免放疗后胸膜炎及肋骨坏死的发生。患者可免遭手术之苦，通过立体定向放疗即可达到治愈目的。本发明获得实施后可填补国内外空白。使立体定向放疗技术在早期肺癌的应用更趋于完善。球囊肺推开器为我自创发明，此前无此类产品研究。但通过此发明将肿瘤组织与胸壁分离，使贴近胸膜的肺癌早期患者通过放疗进行治愈成为可能。The beneficial effects of the present invention are: the lungs and the chest wall are pushed away under minimally invasive conditions, so as to avoid radiation damage to soft tissues such as the pleura, chest wall ribs, and nerves during high-dose radiotherapy, thereby avoiding pleurisy and ribs after radiotherapy. The occurrence of necrosis. Patients can avoid the suffering of surgery, and can be cured through stereotactic radiotherapy. After the present invention is implemented, it can fill up the gaps at home and abroad. Make the application of stereotactic radiotherapy technology in early lung cancer more perfect. The balloon lung pusher is my own invention, and there is no such product research before. However, by separating the tumor tissue from the chest wall through this invention, it is possible to cure early-stage lung cancer patients close to the pleura through radiotherapy.

具体实施方式detailed description
下面将结合本发明实施例中的附图，对本发明实施例中的设计方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The design solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
实施例1Example 1
如图1所示，一种经皮穿刺胸膜腔内留置球囊肺推开器，包括球囊3，所述球囊3内部有可视标记2，所述球囊3一端设有导丝6，所述球囊3另一端有导管4，所述导管4上设有连接头1，所述导管上设有滴管5，所述滴管5上设有压力表7，所述压力表上连接盐水袋8。As shown in Figure 1, a percutaneous puncture indwelling balloon lung pusher in the pleural cavity includes a balloon 3 with a visible mark 2 inside the balloon 3, and a guide wire 6 at one end of the balloon 3 , the other end of the balloon 3 has a catheter 4, the catheter 4 is provided with a connector 1, the catheter is provided with a dropper 5, the dropper 5 is provided with a pressure gauge 7, and the pressure gauge is Connect the saline bag 8.
所述盐水袋8保持300mmHg压力，保持稳定的压力能使球囊均匀的增大，胸腔穿刺针外套管为可撕裂型，可增加患者穿刺后的舒适度。导丝6用于固定球囊3的位置，利用放疗剂量的与距离平方成反比的定律，在将肿瘤推离胸壁一定距离，留下剂量跌落空间留下剂量跌落空间，在从而使需要立体定向放疗的肿瘤组织与胸壁产生距离，以免误伤对放射线耐受性差的正常胸壁组织。The saline bag 8 maintains a pressure of 300mmHg, and maintaining a stable pressure can make the balloon evenly enlarged, and the outer sleeve of the thoracentesis needle is tearable, which can increase the comfort of the patient after puncture. The guide wire 6 is used to fix the position of the balloon 3. Using the law that the radiation dose is inversely proportional to the square of the distance, the tumor is pushed away from the chest wall by a certain distance, leaving a space for the dose to fall, so that stereotaxic therapy is required. The distance between the irradiated tumor tissue and the chest wall is to avoid accidentally injuring the normal chest wall tissue that is poorly tolerant to radiation.
需要说明的是，本发明一种经皮穿刺胸膜腔内留置球囊肺推开器使用方法为：通过特定胸膜腔穿刺针，将本发明导管4送入胸膜腔内既定位置，通过注水口注入无菌生理盐水30-50ml，使球囊3充盈，将肺组织向纵膈方向推离，并进行位置固定。采用微创技术在无菌条件下将本发明装置留置于病人的胸膜腔内，推离肺周围贴近胸壁的肺癌病灶与胸壁产生和保持一定安全距离。待两周放射治疗结束后，去除本装置。It should be noted that the method of using a percutaneous puncture indwelling balloon lung pusher in the pleural cavity of the present invention is as follows: through a specific pleural cavity needle, the catheter 4 of the present invention is sent to a predetermined position in the pleural cavity, and injected through the water injection port. 30-50 ml of sterile saline is used to inflate the balloon 3, push the lung tissue away from the mediastinum, and fix the position. The device of the present invention is placed in the patient's pleural cavity under aseptic conditions by using minimally invasive technology, and the lung cancer focus close to the chest wall around the lungs is pushed away to create and maintain a certain safe distance from the chest wall. After two weeks of radiation therapy, the device is removed.
最后应说明的是：以上所述仅为本发明的优选实施例而已，并不用于限制本发明，尽管参照前述实施例对本发明进行了详细的说明，对于本领域的技术人员来说，其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。Finally, it should be noted that: the above is only a preferred embodiment of the present invention, and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still The technical solutions recorded in the foregoing embodiments may be modified, or some technical features thereof may be equivalently replaced. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
