Hypophysoma cutting and removing device

Abstract

The invention discloses a hypophysoma cutting and removing device. The hypophysoma cutting and removing device comprises an operating rod the interior of which is provided with a sucking hose in a penetrating manner, wherein the sucking hose is connected with a negative pressure sucking machine, a liquid inlet hose is further arranged in the operating rod in a penetrating manner, the rear end part of the liquid inlet hose is connected with a liquid pump, the front end of the operating rod is provided with an operating head capable of rotating in a positioning manner, a sucking head connected with the sucking hose and a liquid knife head connected with the liquid inlet hose are mounted on the operating rod, the liquid knife head comprises a flat tube the rear end of which is communicated with the liquid inlet hose, the front end of the flat tube is provided with a strip-shaped liquid outlet gap allowing liquid to be sprayed out to form a liquid knife, and the operating rod is provided with a sucking controller for controlling the on-off of the sucking hose and the sucking head, and a removing controller for controlling the liquid flow pressure in the liquid inlet hose. The hypophysoma cutting and removing device is simple in structure and convenient to operate, and has the advantages that the operation time is shortened, the operation effect is improved, and the operation injuries are reduced.

Description

technical field [0001] The invention relates to a device for cutting and removing pituitary tumors. Background technique [0002] Pituitary tumors are a group of tumors originating from the anterior pituitary gland. Pituitary tumors usually occur in young adults, and often affect the patient's growth and development, reproductive function, learning and work ability. The clinical manifestations are abnormal hormone secretion syndrome, tumor compression of the surrounding tissues of the pituitary gland, pituitary apoplexy and other pituitary anterior lobe Dysfunctional manifestations. At present, the treatment of pituitary tumors is still mainly surgery, supplemented by drug therapy and radiation therapy. The pituitary tumor is located in the sellar region, surrounded by important nerve structures such as the optic nerve, internal carotid artery, cavernous sinus, and hypothalamus, so surgery still has certain risks. At present, there are two surgical methods: transsphenoida...

Problems solved by technology

[0003] During resection of pituitary tumors, most of the tumors are soft and easy to be cured and sucked under low pressure. Therefore, stripper strippers and suction tubes are mostly used to prevent the tumor "capsule" or sellar septum from collapsing prematurely The resection of tumors around the internal influence should be performed in the order of peripheral resection first and then the center. At present, the method of stripping and curettage or suction through the sphenoid sinus is the main surgical method, that is, the stripper or suction tube is inserted through the sphenoid sinus. During the operation, since the sphenoid sinus is limited in space and needs to be peeped with an endoscope, the surgeon uses the stripper and the suction tube repeatedly and alternately, which greatly prolongs the operation time. Physicians have high requirements for operating skills, and rupture of blood vessels in the "capsule" of the tumor may occur, resulting in subarachnoid hemorrhage, or cerebrospinal fluid leakage due to damage to the sellar diaphragm.
