Embodiment Construction

[0020] In a specific embodiment, the navigator (1) selects an electromagnetic navigator, and the light source of the photodynamic therapy machine (4) selects a semiconductor laser (LD) that can emit a wavelength of 630 nanometers. The photodynamic interventional treatment equipment under the navigation guidance of this design includes an electromagnetic navigator (1) a computer (2) a three-dimensional treatment planning software (3) a laser photodynamic treatment machine (4). Such as figure 2 shown.

[0021] The electromagnetic navigator (1) further includes a probe (5) with a microcoil, a multi-channel signal processor (6) and a magnetic field generator (7). Such as image 3 Shown.

[0022] Probe with micro-coil (5) The micro-coil has a diameter of less than 0.8 mm and a length of about 4 mm. It is placed on the front end of the probe and has an output flexible wire connected to the multi-channel signal processor (6) to be generated by the magnetic field generator (7). A...

Abstract

The invention provides a navigator and three-dimensional treatment planning software, and aims at overcoming the shortages that the solid organ tumor in a human body cannot be accurately positioned and cannot be tracked on real time due to the lack of treatment plan guide in the existing photodynamic interventional surgery. A navigation-guided photodynamic treating device comprises the navigator, a computer, the three-dimensional treatment planning software, a photodynamic treating machine and an auxiliary surgical instrument. The navigation-guided photodynamic treating device is in combination with the nidus of the organ of a patient, and an operator can be guided by the navigator to monitor the moving path of the surgical instrument and correct the error with the planned path on real time, so as to send the optical fibers to a tumor target area of the patient by puncturing by a visual manner in the whole process according to the treatment plan.

Description

technical field [0001] The invention relates to treatment equipment in medical instruments, and more specifically, to a navigation-guided photodynamic interventional surgery treatment equipment. Background technique [0002] Photodynamic therapy is a cold photochemical reaction, the basic elements of which are oxygen, photosensitizer and visible light (usually laser). The photosensitizer is selectively absorbed by the tumor tissue and stored in it, and then the photosensitizer is activated under the local irradiation of the laser with an appropriate wavelength, thereby producing a photosensitizing effect and killing tumor cells. In recent years, due to the development and progress of photosensitive substances, photoactivation devices and light guide systems, this therapy has become one of the basic means of tumor treatment. [0003] At present, photodynamic therapy is mostly used in the treatment of cavity organ tumors in the human body, including esophageal cancer, gastric...
