Bioglue syringe suitable for surgical positioning of tiny nodules in the lung

Abstract

The invention discloses a bio-glue syringe suitable for surgical positioning of tiny intrapulmonary nodules, which comprises a plastic storage bag with a sealed accommodation cavity, the storage cavity is arranged at one end inside the plastic storage bag, and the plastic storage bag is easily deformed when it is under pressure; The middle of the bottom of the plastic bag is fixedly connected with a hollow cylinder communicating with the containing cavity, and the inner wall of the cylinder is provided with an internal thread; the upper end has a transparent hollow tube with a tip, and the upper end of the hollow tube is provided with an external thread that matches the internal thread , the upper end of the hollow tube is sheathed in the cylinder, and is detachably connected with the internal thread in the cylinder. When the upper end of the hollow tube moves toward the cylinder, the tip is used to pierce the diaphragm between the accommodation chamber and the plastic storage bag, so that the biological The glue flows into the containing cavity, and by pressing the plastic storage bag, the biological glue flows into the patient's affected part through the hollow tube; it also includes a hard protective shell arranged outside the plastic storage bag and the cylinder, and the protective shell is arranged along its length or width. Has a tear-off seal. The bio-glue syringe suitable for surgical positioning of tiny intrapulmonary nodules is convenient for medical staff to operate and relieves pain of patients.

Description

technical field [0001] The invention relates to the medical field, in particular to a biological glue syringe suitable for surgical positioning of tiny nodules in the lung. Background technique [0002] In recent years, with the improvement of people's health awareness and the development of multi-slice spiral CT imaging technology, clinically found small solitary pulmonary nodules (SPN), especially groundglass opacity (GGO) more and more. In clinical work, since nearly 50% of small pulmonary nodules are malignant, most scholars believe that if the small pulmonary nodules or ground-glass changes increase within a short period of time, surgical resection should be performed. Surgical methods can be divided into traditional thoracotomy and video-assisted thoracoscopic surgery (VATS). Compared with traditional thoracotomy, video-assisted thoracoscopic surgery has no significant difference in surgical effect. Because of its advantages of minimal invasiveness, fast postoperativ...

Problems solved by technology

Intraoperative ultrasound requires the cooperation of ultrasound equipment. At the same time, for patients with emphysema, the gas in the alveoli will interfere with the identification of nodules by ultrasound. For individual small nodules, the resolution of ultrasound is not enough for identification
