Device for performing puncture biopsy under laser guide

Abstract

The invention belongs to the technical field of medical devices and particularly relates to a device for performing puncture biopsy under laser guide. The device comprises a propelling device and a puncture biopsy device, wherein the puncture biopsy device is fixedly connected to the propelling device; the puncture biopsy device comprises a puncture needle sheath and a sampler, a sampling hole isformed in the front end of the puncture needle sheath, a cutting disc is arranged at the orifice of the sampling hole, a laser sensor and a prompter are arranged at the rear end of the sampler, and the central line of the laser sensor is colinear with the axis of a conical needle head. By means of the propelling device and the puncture biopsy device, the propelling device is used for pushing the puncture biopsy device to move forward to reach the pathological tissue position, the puncture biopsy device is used for cutting down a small piece of pathological tissue and taking out the pathological tissue to be used for follow-up section examination; the laser sensor and the prompter are used for realizing laser guide to prevent skewing of puncture and guarantee puncture accuracy.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a device for puncture biopsy guided by laser. Background technique [0002] Biopsy (biopsy) referred to as "biopsy", also known as surgical pathological examination, referred to as "external examination"; refers to the need for diagnosis and treatment, to remove diseased tissue from the patient's body, such as cutting, forceps or puncture, for pathological examination. Check the technique. It is the most important part of diagnostic pathology. It can make a clear histopathological diagnosis for the vast majority of cases submitted for inspection, and it is used as the final clinical diagnosis. [0003] The diagnosis of many diseases requires pathological section examination. In order to obtain pathological tissue, especially the pathological tissue hidden inside the body, puncture sampling is required. At present, there is a needle aspiration puncture method,...

Problems solved by technology

[0003] The diagnosis of many diseases requires pathological section examination. In order to obtain pathological tissue, especially the pathological tissue hidden inside the body, puncture sampling is required. At present, there is a needle aspiration puncture method, which is to puncture the puncture needle into the mass and then use a syringe The principle of negative pressure suction is to obtain a small amount of pathological tissue or interstitial fluid for diagnosis. However, due to the tissue toughness of pathological living tissues, it is often difficult to aspirate the tissue or the interstitial fluid obtained cannot be used for pathological diagnosis, and the existing puncture The process lacks guidance and requires medical staff to locate the puncture position through experience. There is a possibility of deviation in puncture, and the depth of puncture cannot be accurately grasped.

For beginners or inexperienced medical personnel, the problem of puncture deviation often occurs during use, which damages the tissue and is very dangerous.
