Surgical instrument for establishing posterior sternum space

Abstract

The invention discloses a surgical instrument for establishing a posterior sternum space. The surgical instrument comprises a cleaning rod head, a cleaning rod and a hook rod part which are sequentially connected, wherein the cleaning rod and the hook rod part are detachably connected, a trapezoidal head with the bottom surface inclining upwards is arranged at the end part of the cleaning rod head, and a through hole perpendicular to the surface of the cleaning rod head is formed in the trapezoidal head; and the hook rod part is provided with a fixing plate, the fixing plate is provided with a hook ring, the angle of the hook ring relative to the hook rod part can be adjusted and can be locked at a certain fixed position, and an operation hole is formed in the hook ring. The hook rod part adopts the same incision as the operation, namely a xiphoid lower incision approach, the direction of the hook rod part is consistent with the long axis direction of the sternum, a small incision does not need to be additionally arranged, the possibility of damaging arteries and veins in the thorax is avoided, and the safety traction force is large. The hook rod part is further provided with a smoke exhaust channel which can be connected with a negative pressure suction device, so that the problem that the operation field is fuzzy due to the fact that smoke generated in the use process of an operation energy platform cannot be effectively exhausted is solved. The part further adopts a multi-angle adjustable design, so that an operator can better master the balance of the traction force in the operation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a surgical device for establishing a retrosternal space. Background technique [0002] During the diagnosis and treatment of retrosternal / anterior mediastinal diseases, such as (thoracoscopic) anterior mediastinal tumor resection; (thoracoscopic) pericardial cyst resection, incision and drainage, pericardiectomy and other operations; (thoracoscopic) radical resection of esophageal cancer Establishment of the retrosternal tunnel; (thoracoscopic) surgical treatment of subxiphoid mediastinal / pulmonary diseases, etc., requires the use of a complete set of instruments for the establishment of the retrosternal space. In the prior art, the retrosternal retractor is usually used, but the limitation of the retrosternal retractor is relatively large. The specific performance is that the retrosternal retractor is perpendicular to the long axis of the sternum, and it is necessary to ...
