When in use, the sliding lock block is relatively displaced by the rear end retraction button 14 or the front end retraction button 13, so that the sliding lock block and the retaining ring 213 are triggered to rebound the puncture needle tube 21. The invention is different from the prior art in that after the positioning marker enters the target position, the manual pushing action is not needed, and after the retraction button is pressed, the puncture needle automatically retracts to keep the positioning marker in the affected part, thereby preventing the possibility of inaccurate positioning caused by manual operation after the positioning marker enters the affected part.
When the puncture positioning component 2 needs to be replaced, the cover cap is taken down, and the puncture positioning component 2 is directly replaced; during replacement, the fixing protective sleeve 23 is placed in the front cavity 123 to abut against the unlocking block 1231, and then the puncturing needle tube is held by a hand to be compressed continuously, so that the fixing protective sleeve and the anti-slip groove 257 and the anti-slip protrusion 258 on the retraction sleeve move, the fixing protective sleeve is unlocked, and the trigger structure formed by the locking sliding block, the abutting ring and the spring is respectively contacted with the rear-end retraction button 14 or the front-end retraction button 13.
The puncture positioning component 2 can be replaced conveniently, quickly and efficiently through the structure.
The using method comprises the following steps: the device is guided by B-ultrasonic or other imaging equipment, subcutaneous tissues are punctured, a positioning marker is conveyed to a desired position, a puncture needle retraction button or a handle tail end retraction button of a handle assembly 1 is pressed, and the tail part of the puncture needle retracts to the bottom position of a cavity of the handle assembly 1 under the action of a spring 24 of an inner cavity of the puncture needle positioning assembly, so that the positioning marker is separated from the front inner cavity of the puncture needle and is kept in focus tissues, and the keeping operation of the positioning marker is completed.
The action principle is as follows: after the puncture needle is inserted into the affected part, the unlocking button is pressed by hand to make the sliding lock block slide downwards, the needle tube gets rid of the constraint of the lock block, the puncture needle tube 21 is retracted to the bottom of the inner cavity of the handle component under the action of the spring 24, and the positioning marker is left in the affected part. The needle tube is retracted by the biasing force of the spring 24, and the positioning mark is left on the affected part. When the locking piece is unlocked, the arm is not moved, and no external acting force is exerted. Ensuring that the positioning mark is placed at the correct position.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
