Tumor extractors for oncology

Abstract

The invention discloses a tumor taking device for oncology. The tumor taking device includes a taking piece, a gas pipe and a negative pressure generator; the taking piece is connected to the negativepressure generator through the gas pipe, and the taking piece includes a body, a press handle and a taking pipe; and the interior of the body is provided with a pressure regulating cavity channel anda negative pressure channel, the body is provided with a valve hole, a control valve is installed in the valve hole, the taking pipe is fixedly connected to the pressure regulating cavity end openingof the pressure regulating cavity channel, the taking pipe communicates with the pressure regulating cavity channel, the press handle is hinged on the body, the press handle can press and cooperate with the control valve after being pulled, the bottom of the valve hole is provided with a gas hole, the valve core of the control valve is provided with a gas inlet channel, the gas inlet channel communicates with the gas hole, and the pressure regulating cavity channel communicates with the exterior of the body through the gas inlet channel and the gas hole. The tumor taking device is reasonablein design and convenient to use, and uses the negative pressure principle to effectively take and fix tumors without causing tumor rupture.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a tumor extractor used in oncology departments. Background technique [0002] Tumor refers to the new organism formed by the proliferation of local tissue cells under the action of various tumor-causing factors, because this new organism is mostly in the form of space-occupying blocky protrusions, also known as neoplasm. Under the action, a certain cell in the local tissue loses its normal regulation of its growth at the gene level, resulting in abnormal lesions formed by its clonal abnormal proliferation. There are varying degrees of difference. [0003] When a surgeon performs an operation on a patient, the tumor is generally extracted with medical tweezers during tumor resection. However, when the tweezers are used to extract the tumor, there are only two stress points on the tumor and the force area is small. If it is too small, the tumor cannot be clamped. If the force is...

Problems solved by technology

[0003] When a surgeon performs an operation on a patient, the tumor is generally extracted with medical tweezers during tumor resection. However, when the tweezers are used to extract the tumor, there are only two stress points on the tumor and the force area is small. If it is too small, the tumor cannot be clamped. If the force is too large, it is easy to crush the tumor, which is very inconvenient, and sometimes even adds some unnecessary difficulties to the operation, because it is easy to destroy the tumor focus with hands or instruments , loses the original shape, which affects the surgeon's judgment of the pathological condition of the lesion from its appearance, and has a certain impact on the further diagnosis of the disease. During the operation, the opening is relatively small, and the tweezers are easy to touch the surrounding tissue and cause damage to the surrounding tissue. , and the process of tumor clipping will lead to tumor rupture. After the rupture, the incomplete tumor will have the risk of implantation and metastasis to other parts. There is no good clamping fixture to stably fix the tumor, which makes it necessary to do fine In the tumor resection operation, the accuracy of the operation is not high, and it takes a long time, so the innovation of the complete tumor removal tool is particularly important
