AI Technical Summary

Technical Problem

When existing breast cancer sampling devices deal with breast cancer tissues with diverse textures and complex anatomical structures, it is difficult to achieve rapid, accurate, and low-traumatic sampling, resulting in poor sample integrity, long operation time and high complication risk.

Method used

A tumor quick sampling device is designed, combining negative pressure adsorption with directional cutting wire to ensure that the cutting direction is consistent with the adsorption direction. The cutting wire is driven to move at high speed in the vertical direction with a spring to achieve vertical breaking, and the negative pressure control is assisted with scale marking to improve sampling accuracy and safety.

Benefits of technology

It achieves rapid, accurate and low trauma acquisition of breast cancer samples, reduces the risk of intraoperative bleeding and postoperative complications, and is suitable for scenarios such as laparoscopic surgery that require high operating space and accuracy.

Abstract

The rapid tumor sampling device comprises a lower cylinder body and an upper cylinder body, one side of the top of the upper cylinder body is communicated with an adsorption tube through an opening, a first ring and a second ring are fixedly arranged on the inner wall of the top of the adsorption tube, and a diaphragm is bonded to the inner wall of the corresponding side of the first ring and the second ring; a cutting wire is inserted into a gap between the first ring and the second ring, and the outer walls of the two ends of the cutting wire penetrate through one side of the top of the adsorption pipe to be fixedly connected with the outer wall of the top of the first sliding block. According to the device, through organic combination of directional cutting mechanical design and negative-pressure adsorption positioning, a quick, accurate and low-trauma acquisition mode of a tumor sample is realized, and the controllability of the cutting direction and the path stability are obviously superior to those of a traditional clamping or puncture needle rotary cutting technology; the device is especially suitable for scenes with strict requirements on operation space and precision, such as deep tumor biopsy, and an efficient and safe standardized sampling solution is provided for clinic.
