Tumor puncture localizing needle

Abstract

The invention discloses a tumor puncture localizing needle. The tumor puncture localizing needle is characterized by comprising a sheathing canal (1) and a grasping needle (2), wherein the tip end of the sheathing canal (1) is of a needle-shaped structure and the tail end is provided with operating handles (5); the grasping needle (2) sleeves in the sheathing canal (1); elastic grabbers (3), which are represented as umbrella ribs when expanded, are connected to the front end of the grasping needle (2); the elastic grabbers (3) can be accommodated in the sheathing canal (1); an operating end (4) is arranged at the other end of the grasping needle (2); a small sheathing canal (6) is arranged at the tail end of the grasping needle (2); the elastic grabbers (3) are be gathered into a bundle, so that the elastic grabbers (3) can move in and out of the tail end of the sheathing canal (1) conveniently; small erasers (7) are arranged on the outer wall of the sheathing canal (1); the small erasers can move up and down on the outer wall of the sheathing canal (1); and the small eraser are in charge of controlling a depth of the sheathing canal (1) pierced into a human body. The tumor puncture localizing needle provided by the invention is simple in structure and convenient to use, and the speed and the accuracy of tumor puncture can be greatly enhanced.

Description

technical field [0001] The invention relates to a medical device, especially a puncture positioning needle used in the lung tumor puncture process, specifically a needle that can prevent the position of the lung tumor from moving with breathing movement, so as to facilitate tumor puncture biopsy or Tumor puncture positioning needle for tumor ablation therapy and placement of radiation particle therapy. Background technique [0002] The basis of tumor treatment is pathological diagnosis, which often relies on tumor biopsy. Accurate tumor puncture is very important in order to reduce the damage to normal tissue by puncture. At the same time, the implementation of treatment methods such as tumor ablation therapy and radiation seed implantation therapy also requires precise puncture of the tumor. However, in the actual puncture process, especially for tumors in the lung, mediastinum, etc., due to the influence of the patient's breathing, the tumor location will move within a c...

Problems solved by technology

[0003] The purpose of the present invention is to design a simple tumor puncture positioning needle that can keep the tumor almost immobile, aiming at the problem of difficulty in puncturing due to the indeterminate position of the tumor during puncture biopsy of chest tumors
