Isolation instrument and medical equipment

Abstract

Embodiments of the present invention provide an isolation instrument and medical equipment, and relate to the technical field of medical instruments. The isolation instrument provided by the embodiments of the invention comprises a guide rod and a balloon, and the balloon is connected to the guide rod. The balloon has elasticity, the inside of the balloon is provided with an accommodating cavity for accommodating a medium, the inside of the guide rod is provided with a medium channel communicated with the accommodating cavity; the medium is filled into the accommodating cavity through the medium channel to cause the balloon to deform elastically, so as to change the volume of the balloon; and during isolation, the volume of the balloon is increased by filling the accommodating cavity withthe medium, so as to effectively isolate a nidus from normal organs, and the isolation effect is good. At the same time, the external surface of the balloon is provided with ribs, and the multiple ribs are uniformly arranged around the circumference of the balloon, so that the deformation of the balloon is more uniform when the accommodating cavity is filled with the medium, which helps to improvethe isolation effect.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an isolation device and medical equipment. Background technique [0002] Thermal ablation technology is currently the mainstream clinical tumor treatment method. The main methods include radiofrequency ablation and microwave ablation. The operation is guided by medical images, and implantable radiofrequency ablation needles, microwave ablation needles, etc. The mirror is placed in the tumor tissue, and the temperature is raised to a local high temperature above 50°C through power radiation and maintained for several minutes until the tumor cells are coagulated and necrotic, so as to achieve the purpose of in situ inactivation or local eradication of the tumor tissue. [0003] In thermal ablation, in order to ensure the therapeutic effect, it is generally used to increase the ablation area to achieve the purpose of completely inactivating the lesion, but the transition of ...

Problems solved by technology

[0003] In thermal ablation, in order to ensure the therapeutic effect, it is generally used to increase the ablation area to achieve the purpose of completely inactivating the lesion, but the transition of ablation can easily cause damage to the normal organs around the lesion. In order to improve this problem, clinical practice Normal organs are generally protected by injecting normal saline, but due to the fluidity of water, even injecting a large amount of normal saline often cannot achieve a good protective effect
