Abstract
The utility model relates to a tumor puncturing biopsy needle, which comprises a needle tube with a handheld seat and a needle core. The lower end of the tube body of the needle tube is provided with a beveled opening, and the lowest end of the beveled opening is provided with an inverted hook; and the core body part of the needle core is inserted in the inner hole of the needle tube and is matched with the inner hole in a sliding way, and the lower end of the core body of the needle core is provided with a solid inclined surface matched with the angle of the beveled opening at the lower end of the needle tube. Biopsy tissues can be obtained conveniently, the tumor puncturing biopsy needle has a simple structure and is easy to operate, less damage can be caused to patients, pains of the patients can be eased, and a good clinical effect can be achieved.
Description
Technical field:
This utility model relates to a kind of tumor aspiration biopsy pin, is used for oncology sampling biopsy.
Background technology:
Oncology need be used the aspiration biopsy pin that is made of needle tubing and nook closing member when the sampling biopsy, the body lower end of used needle tubing is the inclined-plane opening, when needle point arrives the sampling of sample position extraction nook closing member, differ and effectively obtain biopsy surely, influence the accuracy of biopsy, perhaps repetitive operation brings more misery to patient.
Summary of the invention:
The purpose of this utility model provides a kind of tumor aspiration biopsy pin, solves original tumor aspiration biopsy pin and is difficult for an accurately convenient difficult problem that obtains biopsy.
The purpose of this utility model realizes as follows: this tumor aspiration biopsy pin, comprise the needle tubing and the nook closing member of the hand-held seat of band, the body lower end of needle tubing is the inclined-plane opening, the inclined-plane opening barb arranged bottom; The core body of nook closing member partly is inserted in the needle tubing endoporus and is slidingly matched with this endoporus, and the core body lower end of nook closing member is the solid inclined-plane that matches with inclined-plane, needle tubing lower end opening angle.During use, the needle tubing that will have nook closing member thrusts human body sampling organ, after making the arrival biopsy position, body lower end of needle tubing, pull back nook closing member one segment distance, spur needle tubing then and break away from human body, the barb of needle tubing cuts the part biopsy and is trapped in the needle tubing endoporus, easily obtains biopsy samples.
This utility model can conveniently obtain biopsy, and is simple in structure, and operation is little to patient's damage easily, has alleviated patient's misery, and clinical effectiveness is good.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
With reference to accompanying drawing, this tumor aspiration biopsy pin comprises the needle tubing 1 and the nook closing member 2 of the hand-held seat of band, and the body lower end of needle tubing 1 is the inclined-plane opening, the inclined-plane opening barb 3 arranged bottom; The core body of nook closing member 2 partly is inserted in needle tubing 1 endoporus and with this endoporus and is slidingly matched, and the core body lower end of nook closing member 2 is the solid inclined-plane that matches with inclined-plane, needle tubing 1 lower end opening angle.
