Problems solved by technology

In this environment, it is required that there should be no objects with magnetic and electromagnetic properties, such as magnetic metal products such as iron and nickel, which will interfere with imaging; in addition, in an alternating magnetic field, objects with good conductivity such as metal and carbon fiber products will The generation of eddy currents, and then heat may cause damage to the human body, so there should be no such items
The control of light involves the need for a device that can control the state of the optical fiber in real time, and at the same time cannot interfere with the normal operation of the magnetic resonance imaging equipment, nor can it be interfered by the magnetic resonance imaging equipment so that it cannot work normally or cause harm to the human body. accidental injury

Abstract

The invention discloses a driving mechanism suitable for a magnetic resonance imaging environment and a laser ablation treatment head. The driving mechanism comprises a body part and a driving part, one end of the driven object is connected with the driving part, and the driving part comprises an axial movement driving part and a rotary movement driving part; the driven object is driven by the axial movement driving part to reciprocate along the axis direction of the driving mechanism; the driven object is driven by the rotary motion driving part to rotate around the axis of the driving mechanism; and the body part and the driving part are made of engineering plastics. The driving mechanism is made of engineering plastics, the engineering plastics do not have conductivity, magnetism and electromagnetic characteristics, and the engineering plastics have the performance close to that of metal, so that the use requirement of a magnetic resonance imaging environment is met; the driving part comprises the rotary motion driving part and the axial motion driving part, the two parts can work independently and can also work cooperatively, linear motion and rotary motion of the treatment head assembly are achieved, and the driving effect is more accurate and sensitive.

Description

technical field [0001] The invention relates to the technical field of laser optical fiber treatment heads, in particular to a driving mechanism suitable for use in a magnetic resonance imaging environment and capable of longitudinal reciprocating movement and forward and reverse rotation of the treatment head, and a treatment head with the drive mechanism. Background technique [0002] Human tissue ablation surgery is a minimally invasive surgical method developed in recent years. It uses light to transmit laser light to the lesion and heat the lesion to solidify and inactivate the diseased tissue in the human cavity. This surgical method has no radiation, produces small wounds, and recovers quickly after surgery. It has applications in tumor treatment and epilepsy treatment. Especially in the treatment of epilepsy, a very good therapeutic effect can be achieved through ablation of the interstitium, and this surgical method has been approved in many regions. [0003] Becau...
