Abstract

The invention discloses a split-connection cryoablation needle and a needle-head assembly and needle-tail assembly thereof. The split-connection cryoablation needle comprises a needle-head assembly and a needle-tail assembly which are detachably connected; a first detachable connecting structure and a second detachable connecting structure are matched to form detachable connection, and are configured to the mode that an extending section of a first double-layer nesting pipe is inserted into a medium pipe of a second double-layer nesting pipe. The safe antibacterial requirement can be met onlyby replacing the needle-head assembly after operation every time, the needle-tail assembly can be recycled after disinfection, raw materials can be saved, and waste is avoided; compared with the priorart, on the basis that the heat exchanging requirement in the treatment process is met, in the technical scheme, cost consumption of the cryoablation needle in an ablation operation can be reduced, thus the consumable cost of the ablation operation can be effectively reduced, and it is guaranteed that the doctor seeing cost of a patient is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a split-connected cryoablation needle and a needle head assembly and a needle tail assembly. Background technique [0002] Cryoablation is a surgical technique that uses freezing to eliminate target tissue. During the operation, an ablation needle is used to deliver a low-temperature medium to the affected part of the patient, so that the heat of the tissue can be taken away by the heat-absorbing evaporation of the liquid refrigerant, and the temperature of the target ablation site can be lowered. Reduce, thereby destroying abnormal electrophysiological cells and tissues to achieve therapeutic purposes. [0003] The existing cryoablation needle has an integrated structure, including a needle part and a needle tail pipeline part. The needle part is used to directly act on the human body, and the needle tail pipeline is used to connect to the host device for cryoablation su...
