Embodiment Construction

[0070] One object of the present invention is to provide a single-sleeve optical fiber conduit with a cooling function. The optical fiber conduit is designed as a single-sleeve structure. In this structure, both The cooling circulation water circuit including the water inlet chamber and the water outlet chamber greatly reduces the volume of the fiber optic catheter, making it more suitable for minimally invasive operations such as tumor ablation.

[0071] In the following, the present invention will be described in detail in conjunction with the accompanying drawings and specific examples, with the background of tumor hyperthermia technology, in which the schematic examples and descriptions are only used to explain the present invention, but not as a limitation to the present invention. In addition, in order to better explain the creation of the present invention, the proximal end mentioned in the present invention is the end of the optical fiber close to the lesion tissue, and...

Abstract

The invention discloses an optical fiber conduit cooling system capable of removing fluid bubbles. The optical fiber conduit cooling system comprises an optical fiber conduit, the optical fiber conduit is only composed of an optical fiber and a sleeve arranged outside the optical fiber in a sleeving mode, a plurality of interval parts are arranged in the mode that the inner wall of the sleeve extends towards the axis direction of the sleeve, a plurality of gaps which extend in the length direction of the sleeve and are not communicated with one another are formed among the optical fiber, the sleeve and the interval parts, one part of the gaps form a water inlet channel, and the other part of the gaps form a water outlet channel; and one end of the water inlet channel is communicated with one end of the water outlet channel, the other end of the water inlet channel is communicated with a cold source, and the other end of the water outlet channel is used for discharging the cold source. According to the optical fiber conduit with the single-sleeve structure, the coaxiality and the straightness of the optical fiber and the sleeve become very easy. The invention further provides a method for eliminating bubbles from the cooling liquid distribution system. The method ensures that the liquid entering the optical fiber guide pipe is free of bubbles.

Description

technical field [0001] The invention belongs to the field of cooling circulation equipment and cooling liquid distribution of medical technical equipment, in particular to an optical fiber catheter cooling system capable of removing fluid bubbles. Background technique [0002] Hyperthermia is the fifth leading cancer therapy after surgery, radiotherapy, chemotherapy and immunotherapy. The basic principle of tumor hyperthermia is to use physical energy to heat the whole body or part of the human body, so that the temperature of the tumor tissue rises to the effective treatment temperature, and lasts for a certain period of time, using the difference in temperature tolerance between normal tissue and tumor cells to achieve both tumor The therapeutic purpose of apoptosis without damaging normal tissues of the body. Current clinical tumor hyperthermia mainly adopts local hyperthermia, and the heat sources used include: infrared rays, hot water baths, hot baths, ultrasonic waves...
