Pulmonary lobe occlusion device for minimally invasive surgery of thymoma

Abstract

The invention provides a pulmonary lobe occlusion device for a minimally invasive surgery of thymoma. The device comprises a push rod, a sleeve rod, a front support plate, a rear support plate, a compression spring, a connecting rod and a trachea device, and a push rod straight rod of the push rod is inserted into a sleeve rod straight rod of the sleeve rod; the compression spring sleeves the pushrod straight rod of the push rod, and is located between the push rod and the sleeve rod; the right end of the push rod straight rod of the push rod is welded with a pin rod; the front support plateis disposed on the right side of the push rod, the front support plate and the push rod are connected by the connecting rod, one end of a pin hole of the connecting rod is mounted on the pin rod, andthe other end is mounted on a connecting plate of the front support plate; the rear support plate is disposed on the rear side of the front support plate, and the rear support plate and the push rod are also connected by the connecting rod; the trachea device is disposed inside the sleeve rod straight rod of the sleeve rod and located at the upper end of the push rod straight rod of the push rod;the device effectively blocks opened pulmonary lobes and protects a lung tissue; the cooperation use of the trachea device and a compression airbag increases the opened occlusion area, and the removalrange is larger.

Description

technical field [0001] The invention relates to the technical field of medical instruments for minimally invasive surgery, in particular to a lung lobe shielding device for minimally invasive surgery of thymoma. Background technique [0002] Thymus is an important lymphoid organ of the body, its function is closely related to immunity, and it is the place where T cells differentiate, develop and mature. It can also secrete thymus hormones and hormone-like substances. It is an organ with endocrine function, which is located in the front part of the upper mediastinum of the thoracic cavity. Thymoma is a disease caused by lesions around the thymus. It mostly occurs in middle-aged and elderly people. The incidence of men and women is basically the same. The clinical manifestations are cough, chest pain, dysphagia, dyspnea, hoarseness, neck mass and superior vena cava obstruction syndrome. Some patients may be asymptomatic and only found on chest X-ray examination. Once a thymo...

Problems solved by technology

[0004] However, in the minimally invasive surgery for thymoma, the lungs expand and contract in the chest cavity, which blocks the sight of the operator to remove the thymoma, affects the operation of the operator, and easily causes damage to the lung tissue, which also brings many difficulties to the operator. It is inconvenient, so a lung lobe shielding device for minimally invasive surgery is needed to effectively block the expanded lung lobes and protect lung tissue; however, the shielding range of the lung lobe shielding device is limited, and a lung lobe shielding device with a large shielding range is needed to ensure more extensive thymoma resection
