Embodiment Construction

[0013] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0014] see figure 1 and figure 2 The shown rib rongeur under thoracoscopy includes a fixed handle 110, a movable handle 120, a lower clamp piece 210, an upper clamp piece 220, and a compression spring 300. The upper ends of the fixed handle 110 and the movable handle 120 are hinged by a pin shaft 400, Two ends of the compression spring 300 are respectively connected to the inside surfaces of the fixed handle 110 and the movable handle 120 .

[0015] The top of the fixed handle 110 is integrally formed with the lower forceps 210, and the front end of the lower forceps 210 is provided with a occlusal groove 213. The length of the occlusal groove 213 is 15mm, the width is 10mm, and the height is 9mm, which is compatible with the size of human rib...

Abstract

The invention discloses a rib rongeur used under a thoracoscope. The rib rongeur comprises a fixed handle, a movable handle, a lower rongeur piece, an upper rongeur piece and a compressed spring. The compressed spring is connected between the fixed handle and the movable handle, the upper end of the fixed handle is hinged to the upper end of the movable handle through a hinge part, the top of the fixed handle and the lower rongeur piece are integrally formed, and the top of the movable handle is connected with the tail of the upper rongeur piece. The rib rongeur used under the thoracoscope is characterized in that a rib biting groove is formed in the front end of the lower rongeur piece, a conical cutter portion is arranged at the front end of the upper rongeur piece, and the conical cutter portion moves back and forth in the rib biting groove. The rib rongeur is used in the thoracoscope operation, only a small incision needs to be cut in the chest wall, the rib rongeur is extends into the thoracic cavity of the human body through the small incision, then rib biting groove is aligned to the portion which needs to be excised, and then rib excision is conveniently achieved. No large incision needs to be cut in the chest wall, and the operation risk and pain of a patient are greatly reduced.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a rib rongeur under a thoracoscope. Background technique [0002] Lung cancer is a malignant tumor that threatens human health. With the development of routine health checkups and the advancement of influential medical technologies such as thin-section CT examinations, more and more lung cancer patients can be detected and treated early. At present, patients with early lung cancer with small pulmonary nodules are generally treated by thoracoscopic surgery, which is a minimally invasive surgery, and the patient feels less pain and recovers quickly after surgery. However, lung cancer most often metastasizes directly or invades adjacent ribs. In the past, regardless of the size of the nodule, if local rib metastases were found in lung cancer patients, minimally invasive thoracoscopic surgery was generally given up, and a conventional posterolateral incision (about 30 cm in length...
