Neurosurgical tumor extraction device

Abstract

The invention discloses a neurosurgery tumor extraction device, and belongs to the field of medical instruments. The device comprises an adsorption head and a negative pressure pipe, the adsorption head comprises a round-head adsorption head and a connecting pipe, and an adsorption channel is formed in the center of the round-head adsorption head; a first groove is formed around the top end of theadsorption channel; and the negative pressure pipe comprises a supporting pipe and an air pipe, and a cavity is formed between an inner concave of the supporting pipe and the adsorption channel. Theround-head adsorption head of the device can effectively prevent blunt devices from injuring nervous tissues. The adsorption channel is formed in the center of the round-head adsorption head and can provide negative pressure. Negative pressure is generated through the air pump, and the device is large in pressure, capable of achieving thorough adsorption, capable of improving the operation process, good in stability, convenient to operate, suitable for different operation environments and good in adaptability.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a neurosurgery tumor extraction device. Background technique [0002] Tumor refers to a new organism formed by the abnormal growth of monoclonal abnormal growth due to the change of genes under the action of carcinogenic factors and the loss of normal regulation of its growth. At present, most of the treatment of tumors is surgical resection. For the resection of tumors in surgical operations, hospitals usually use vascular forceps to clamp and pull them to achieve the purpose of removing tumors during surgical treatment. The disadvantages are: the use of vascular forceps When clamping, when the clamp opens the opening, it takes up a lot of space, and the clamp is easy to cause tissue damage. And neurosurgery, because nerve tissue is fine, generally adopt negative pressure type extraction device, such as a kind of neurosurgery operation negative pressure type tumor extraction devi...

At present, most of the treatment of tumors is surgical resection. For the resection of tumors in surgical operations, hospitals usually use vascular forceps to clamp and pull them to achieve the purpose of removing tumors during surgical treatment. The disadvantages are: the use of vascular forceps When clamping, when the clamp opens the opening, it takes up a lot of space, and the clamp is easy to cause tissue damage

However, the suction pressure of the syringe is small and the adsorption is not complete

At the same time, because it is easy to cause the liquid to flow back, it will affect the vision
