Handheld electric particle implantation device driven by linear motor

Abstract

The invention provides a handheld electric particle implantation device driven by a linear motor, and belongs to the field of medical instruments. The handheld electric particle implantation device ischaracterized in that a guide rail is installed on a body, wherein a first sliding block and a second sliding block are installed on the guide rail; a front baffle is installed at the front end of the guide rail; a linear motor stator is installed on the body; a linear motor rotor is installed on the lower face of the first sliding block and matched with the linear motor stator; a flat plate is installed on the first sliding block; an inner needle driving mechanism, a shifting rod mechanism and a clip module are installed on the flat plate; the clip module is in threaded connection with a quick connector; the quick connector is connected with a puncture needle; an outer needle driving button and an inner needle driving button which are installed on a handle of the body are used for controlling the linear motor and the inner needle driving mechanism to move; a speed adjusting knob is used for controlling the movement speed of the linear motor; a battery is installed at the tail of thebody and provides power for the whole mechanism; a middle supporting structure is installed on the second sliding block; the puncture needle is prevented from being stressed and bent in the working process; and the supporting effect is achieved. By means of the device, horizontal and vertical needle insertion at a certain angle can be achieved, and the problems existing in an existing device are solved.

Description

technical field

[0001] The invention relates to a hand-held electric particle implantation device driven by a linear motor, which belongs to the field of medical equipment. Background technique

[0002] Brachytherapy is one of the important methods in cancer treatment. It has been recognized and accepted by doctors and patients because of its definite curative effect, no side effects, small trauma, and quick recovery. At present, in terms of particle implantation treatment at home and abroad, most of the radioactive particles are manually implanted into the lesion by doctors one by one. During the operation, doctors need to be highly focused, and the hands and eyes are consistent to ensure the accuracy of particle implantation. , The requirements for doctors are high, and due to the long operation time, it is easy to cause fatigue, and it is difficult to guarantee the quality of the operation.
