Tumor sampling device facilitating tumor separation

Abstract

The invention discloses a tumor sampling device facilitating tumor separation. A moving assembly drives an opening assembly and a sampling assembly to move left and right; a lifting assembly drives the opening assembly and the sampling assembly to move up and down, so that the sampling accuracy of the device can be improved, and the sampling error is small; the opening assembly is arranged, so that skin and flesh at the wound can be prevented from blocking the tumor and affecting the sight of sampling personnel; the output end of a servo motor drives a third screw rod to rotate, the third screw rod drives a moving cylinder and a sampling mechanism to move downwards, meanwhile, the third screw rod drives the lower portion of a sampler to be opened through a linkage assembly, when a tumor is located in an inner cavity of the sampler, the output end of the servo motor rotates reversely, a winding rope is released from a winding wheel, and under the action of a second spring, two sampling devices are closed, the tumor is cut through the cutting edges, the opposite ends of the two sampling devices are provided with the cutting edges in the circumferential direction, and the tumor can be rapidly cut and separated from surrounding tissue.

Description

technical field [0001] The invention relates to the technical field of tumor sampling devices, more specifically, it relates to a tumor sampling device for conveniently separating tumors. Background technique [0002] Tumor refers to the new organism formed by the proliferation of local tissue cells under the action of various tumorigenic factors, because this new organism is mostly in the form of space-occupying blocky protrusions, also known as neoplasm; studies have found that tumor cells will appear differently. Metabolic changes in normal cells, while tumor cells themselves can adapt to changes in the metabolic environment through the conversion between glycolysis and oxidative phosphorylation; [0003] According to the cell characteristics of new organisms and the degree of harm to the body, tumors are divided into two categories: benign tumors and malignant tumors; malignant tumors can be divided into carcinoma and sarcoma. Refers to malignant tumors that occur in me...

Problems solved by technology

[0004] After the doctor finds a tumor, he needs to take a sample to test whether the tumor is malignant or benign, so as to facilitate the doctor's symptomatic treatment. When the existing tumor sampling device is used, it is found that most of the existing devices have a relatively simple structure. When sampling the tumor, due to unstable It is too high to achieve accurate positioning, which leads to deviations in sampling, so that the sample after sampling does not conform to the expected sample, which is inconvenient for follow-up observation or inspection, and reduces work efficiency; and most of the existing devices do not have The structure of opening the surgical wound at the tumor will cause the skin and flesh at the surgical wound to block the sight of the sampling personnel, which is not conducive to the sampling operation; at the same time, when the existing device samples the tumor, the tumor sample is not easy to be cut and separated. This requires multiple cuts of the sample to separate the sample, which is time-consuming and laborious, and will cause some pain to the patient. Therefore, we propose a tumor sampling device that is convenient for separating tumors
