Multi-point biopsy sampling device for breast tumor minimally invasive surgery

Abstract

The invention provides a multi-point biopsy sampling device for breast tumor minimally invasive surgery, and relates to the technical field of sampling devices. The pincer handle assembly comprises a first pincer handle, a second pincer handle, an arc-shaped inserting plate, a driving column and a limiting rod, the first pincer handle and the second pincer handle are rotationally connected through a rotating shaft, the left side of the upper end of the first pincer handle is fixedly connected with a long cylinder part, and a sampling mechanism is arranged at the left end of the long cylinder part. According to the sampling device, through the arrangement of the locking assembly, the phenomenon that two clamping pieces are opened during sampling can be avoided, the stability during pathological tissue clamping is improved, through the arrangement of the medicine pumping mechanism, medicine applying operation can be conveniently carried out on a pathological part, the practicability of the sampling device is improved, and the problem that when an existing sampling device is used for sampling, the sampling efficiency is greatly improved is solved. The problems that in the prior art, due to the fact that two clamping pieces are opened, the stability of clamping diseased tissue is reduced, and an existing sampling device is single in function and inconvenient to apply medicine to the diseased part are solved.

Description

technical field [0001] The invention relates to the technical field of sampling devices, in particular to a multi-point biopsy sampling device for breast tumor minimally invasive surgery. Background technique [0002] Breast tumors are lumps that occur in the breast, and breast lumps are the most common symptoms of breast cancer. During the treatment of breast tumors, a biopsy is required. Biopsy is to take out the diseased tissue from the patient's body, clamp or puncture, and perform pathology. Examination techniques, and biopsy sampling devices are usually required during biopsy. [0003] In the current sampling device, although the two clamp handles can be grasped to clamp the diseased tissue, the two clamps after clamping the diseased tissue, due to the lack of effective The shielding structure makes the clamped diseased tissue easy to fall off, thus reducing the reliability of the sampling device in use, and the current sampling device needs to hold the two clamp hand...

AI Technical Summary

Problems solved by technology

[0003] Although the current sampling device can grasp the lesion tissue by grasping the two gripper handles tightly when sampling, the two grippers cannot grasp the diseased tissue due to the lack of effective The shielding structure makes it easy for the clamped diseased tissue to fall off, thereby reducing the reliability of the sampling device during use, and the current sampling device needs to hold the two pliers handles tightly during sampling. Loosening will cause the opening phenomenon of the two clamping parts, thereby reducing the stability of the two clamping parts when clamping the diseased tissue, and the current sampling device has a single function, which cannot be convenient for the operation of applying medicine to the lesion, thus Reduced utility of sampling devices
