Embodiment Construction

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0035] Figure 1 to Figure 3 Schematically shows a tumor thrombus retrieval device according to the first embodiment of the present invention.

[0036] Such as Figure 1 to Figure 5 As shown, the tumor thrombus retrieval device includes an outer sheath 20, an inner sheath 70, a mobile unit 50, and a thrombus remover 30; wherein, the outer sheath 20 is integrally formed or processed with an accommodation cavity 23, and the outer sheath 20 Both ends of the outer sheath tube 20 communicate with the outside, one end of the outer sheath tube 20 is the front end 21, and the other end is the rear end 22, the outer sheath tube 20 is set to be able to be placed inside the portal vein, specifically, the outer sheath tube 20 The diameter of the tube is set to be smaller than the inner diameter of the pipeline (such as a blood vessel) with tumor thrombus 60 in the tumo...

Abstract

The invention discloses cancer embolus taking apparatus. The apparatus includes an external sheath tube, an internal sheath tube, a moving unit and an embolus taking device; the internal sheath tube is movably arranged in the external sheath tube; the moving unit is movably arranged in the internal sheath tube; the embolus taking device is arranged at the end part, located on the same side with the front end of the external sheath tube, of the moving unit; the embolus taking device is made of a memory material which can deform, so that the embolus taking device can have an initial unfolding state of a basket-liked structure when the embolus taking device is located at the external of the internal sheath tube, and have a contraction state when the embolus taking device is located in the internal sheath tube; and a catcher is also arranged into a device that, at the initial unfolding state, the opening of the basket-liked structure faces toward the moving unit, so that the front end of cancer embolus can be caught. As the external diameter of the apparatus is small when the embolus taking device is located in the internal sheath tube, the performing of an operation can be avoided, percutaneous transhepatic minimally invasive surgery can be adopted, and the apparatus can be adopted to take out the cancer embolus under the circumstance of locating the cancer embolus through B-ultrasound or X-ray.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tumor thrombus retrieval device. Background technique [0002] As one of the common complications of tumor patients, cancer thrombus affects the survival period and quality of life of cancer patients. When cancer thrombi occurs in important tissues and organs of the human body, it may also endanger the life of tumor patients. Therefore, removing cancer thrombus from tumor The extraction from the patient's body is particularly important for delaying the progression of the tumor patient's condition and improving the survival rate and quality of life of the tumor patient. Existing thrombectomy methods generally require the use of tumor thrombus retrieval forceps to remove the tumor thrombus from the body of a tumor patient under the condition of an operation. The medical curved liver cancer portal vein tumor thrombectomy forceps all disclose a kind of tumor thrombus retri...
