Anti-clogging sampling structure and sampling probe with same and sampling system with sampling probe

Abstract

The invention relates to an anti-clogging sampling structure and a sampling probe with the same and a sampling system with the sampling probe. According to the anti-clogging sampling structure, an elastic device is arranged in an anti-clogging sampling channel, a puncture head is connected to one end of the elastic device, and the other end of the elastic device is always in an inner tube during the sampling process. A certain space always exists between the elastic device and the inner wall of an outer tube to prevent the size of tissue adsorbed into the anti-clogging sampling channel duringthe sampling process from exceeding the size of the anti-clogging sampling channel, so that the anti-clogging effect is achieved. The anti-clogging sampling structure further includes two fluid flow channels, the two fluid flow channels are disposed at both ends of a sampling tank, and the tissue is fixed by negative pressure suction. The anti-clogging sampling structure and the sampling probe with the same and the sampling system with the sampling probe have the beneficial effects that through the arrangement of the elastic device and the two fluid flow channels, the anti-clogging performanceof the channel is effectively improved, the integrity of tissue cutting is ensured, the functions of tissue adsorption, rotary cutting sampling, and surgical site irrigation are combined together, and the one-time success rate of a surgery is improved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an anti-clogging sampling structure, a sampling needle with the structure and a sampling system thereof. Background technique [0002] In recent years, with the continuous improvement of medical examination methods and methods, the accuracy of tumor diagnosis has gradually increased, and the early detection of tumors is of great significance to the treatment of diseases. To determine whether a tumor is benign or malignant, it is necessary to obtain tumor cell tissue through biopsy and rely on pathology for confirmation. Biopsy includes two forms of puncture-cut and open biopsy. In clinical practice, a puncture needle is often used to obtain tumor tissue samples. In addition, compared with traditional surgical resection, minimally invasive resection has many advantages such as less trauma, shorter operation time, less pain for patients, and faster postoperative recovery, etc., ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an anti-clogging sampling structure by combining biological histology and fluid dynamics design, which can effectively solve the problems of pipeline blockage and tissue incompleteness in tissue biopsy or minimally invasive resection. At the same time, the functions of tissue adsorption, rotary cutting sampling, and surgical site washing are combined to improve the first-time success rate of surgery and improve the safety and reliability of biopsy sampling or minimally invasive surgery.
