An insertable probe for cryotherapy for liver cancer

Abstract

The invention discloses a novel inserted-type liver cancer cryotherapy probe. The probe comprises a handle, a first electric retractable rod is arranged in the inner cavity of the handle, the upper surface of the handle is provided with a first switch and a second switch separately, the first switch is electrically connected with an external power supply and a first electric retractable rod separately, and the end portion of the first electric retractable rod penetrates out of the side surface of the handle and is connected with a working rod. According to the novel inserted-type liver cancer cryotherapy probe, the working rod is separated from and not in contact with the probe and a heat insulation pipe, the heat insulation effect is better, and surrounding organs and cells are unlikely to be damaged; during the treatment, a patient cannot feel uncomfortable, and the treatment effect is improved; a heat insulation layer is arranged in each movable plate, sealing rubber pads are arranged on the surfaces of the contact sides of the two movable plates, and the heat insulation effect is improved; the surface of the lower side of the handle is provided with a ring, and the surface of inner side of the ring is provided with a non-slip pattern, so that the probe is more stable to take and convenient to use during operation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a plug-in cryotherapy probe for liver cancer. Background technique [0002] With the continuous advancement of medical technology, many new treatment methods have emerged while the traditional liver cancer treatment methods are gradually improving. Cryotherapy is one of them, and it also plays a prominent role in the treatment of liver cancer. The therapy is mainly suitable for patients with small tumors that cannot be removed or those with small nodules in the remaining liver after resection of the main tumor. [0003] The principle of cryotherapy is to use low temperature to form crystals inside and outside the cells, rupture the nucleus and cell membrane, protein denaturation, pH value change, blood stasis and microthrombosis, resulting in local tissue ischemia and necrosis to achieve therapeutic purposes. Most of the existing plug-in liver cancer cryotherapy probes a...

AI Technical Summary

Problems solved by technology

Most of the existing plug-in liver cancer cryotherapy probes are integrated with the heat insulation part, the heat insulation effect is poor, and it is easy to cause damage to the surrounding organs and cells, which makes the patient feel uncomfortable during treatment and affects the treatment effect
