消融手术隔离装置
By setting a deformable cannula and a sac on the catheter and using a compression component to control the deformation of the deformable cannula, the problem of increased catheter weight caused by large fluid injection volume is solved, thereby increasing the expansion range and facilitating surgical operations.

Abstract
Claims
1. An ablation procedure isolation device, comprising: include: A catheter having a tip for insertion into the human body, wherein the catheter has a liquid inlet channel for introducing liquid, the liquid inlet channel extending along the length of the catheter; A deformable sheath is connected to the periphery of the conduit. One end of the deformable sheath is connected to the conduit, and the other end is connected to a compression assembly. The compression assembly compresses one end of the deformable sheath, moving it along the length of the conduit. The middle portion of the deformable sheath bulges away from the conduit. A bladder is provided on the surface of the deformable sheath opposite to the conduit. The bladder and the deformable sheath enclose a chamber, which communicates with the liquid inlet channel. A handle is located at the end of the conduit away from the tip and has a groove, and one end of the extrusion assembly is slidably disposed within the groove.
2. The ablation procedure isolation device of claim 1, wherein, The conduit has an installation groove on its periphery, the deformable sleeve is installed in the installation groove, and one end of the sleeve moves along the length of the installation groove via the extrusion assembly.
3. The ablation procedure isolation device of claim 1, wherein, The extrusion assembly includes a connecting part, a push rod, and a slider. The connecting part and the slider are respectively connected to the two ends of the push rod. The end of the deformable sleeve is connected to the connecting part, and the slider slides in the groove.
4. The ablation procedure isolation device of claim 3, wherein, The portion of the conduit away from the tip has a through groove for mounting the push rod.
5. The ablation procedure isolation device of claim 4, wherein, The push rod and the through slot are each provided in three locations, arranged in a circular array.
6. The ablation procedure isolation device of claim 3, wherein, The handle is provided with an anti-slip block, and the surface of the anti-slip block facing the handle is provided with a locking protrusion. The bottom wall of the groove is provided with a locking groove corresponding to the locking protrusion. The anti-slip block is installed on the handle through the locking protrusion and the locking groove to restrict the movement of the slider.
7. The ablation procedure isolation device of claim 1, wherein, The end of the conduit near the handle is provided with a connecting pipe that connects to the liquid input channel, and one end of the connecting pipe is provided with a one-way valve.
8. The ablation surgery isolation device according to claim 1, characterized in that, The deformable sleeve is thermo-pressed to the bladder body.
