Hollow tubular multi-warhead nano tumor heat therapy instrument

Abstract

The invention discloses a hollow tubular multi-warhead nano tumor heat therapy instrument, which comprises an injection inner cavity, one end of which is provided with a T-shaped plug, wherein the outer side of the other end of the injection inner cavity is provided with an inner cavity convex edge; a coaxial injection outer cavity is outside the injection inner cavity; the inside diameter of theinjection outer cavity is equal to or slightly greater than the sum of the outside diameter of the injection inner cavity and the height of the inner cavity convex edge; the inner side, close to one end of the T-shaped plug, of the injection outer cavity is provided with an outer cavity convex edge; the height of the outer cavity convex edge is equal to or slightly smaller than the height of the inner cavity convex edge; the other end of the injection outer cavity is provided with a closed connecting plate; after a cavity probe passes through the connecting plate, the probe tail is positionedin the injection outer cavity, and the probe body of the cavity probe is positioned in a probe outer tube; one end of the probe outer tube is a cylindrical tube body, positioned outside the injectionouter cavity and coaxial with the injection outer cavity; and the other end of the probe outer tube is a conical tube body with an open conical end. The invention has the advantage that: a plurality of injection needles spread to form an umbrella shape and encircle the tumor after penetrating the tumor, so that secondary trauma caused by interventional therapy is avoided.

Description

technical field [0001] The invention belongs to the field of medical equipment, relates to an instrument in the field of tumor treatment, in particular to a hollow tube type multi-warhead nanometer tumor hyperthermia instrument. Background technique [0002] For a long time, how to effectively eliminate tumors has been a major goal pursued by the academic and clinical medical circles. Compared with tumor treatment measures such as surgical resection, chemotherapy and radiotherapy, tumor hyperthermia has less side effects and harm, so it is known as "green therapy". Tumor hyperthermia is to increase the temperature of tumor tissue and its surrounding tissue through various heating methods. When the tumor tissue is heated to a certain temperature, it can kill tumor cells. At the same time, normal cells have better heat resistance than tumor cells, so Under the same heating conditions, it is not easy to be burned, so it can protect normal tissues to a certain extent.

AI Technical Summary

Problems solved by technology

[0005] In direct injection, if it is single-needle injection, since the nanoparticle solution will not diffuse quickly after being directly injected into the tissue, it will even be blocked by the tissue network, so the nanoparticles are usually concentrated in the small area around the injection point. In this range, the surrounding tumor tissue does not reach the predetermined temperature value because the nanoparticles are not distributed; if it is changed to multiple injection needle injections, it will cause obvious interventional mechanical trauma to the tissue, and in some cases may also be in the In the process of inserting into the body, it will cause trauma to the large blood vessels, resulting in obvious bleeding. The adverse effects on the treatment and rehabilitation cannot be ignored, and it needs to be improved urgently.
