Description

Technical Field

[0001] The utility model relates to the technical field of ablation isolation protection, in particular to an ablation isolation protection device. Background Art

[0002] Ablation technology uses an ablation needle to puncture directly into the tumor site and kill tumor cells through microwave or radio frequency. However, ablation technology has a certain probability of destroying normal tissue, so it is necessary to separate and protect the diseased tissue and normal tissue before microwave ablation to prevent normal tissue from being damaged during the ablation process.

[0003] China's invention patent (patent number 202211482326.3) is an isolation and protection device for ablation surgery. It uses a syringe to inject liquid into the filling cavity and balloon through a connecting tube and a control valve, and then checks whether the support effect meets the isolation and protection requirements with the assistance of CT or ultrasound; if it does not meet the requirements, loosen the spiral head and the locking tube, adjust the position of the sealing sleeve by moving the slider, and then inject liquid into the balloon again, and so on. This method of injection is cumbersome and requires frequent manual adjustment of the spiral head and the locking tube, manual movement of the slider and the sealing sleeve. The operation is cumbersome and inefficient. Utility Model Content

[0006] A telescopic chamber is provided in the handle, a servo motor is provided at the tail end of the telescopic chamber, a nut seat is provided at the tail end of the adjusting sleeve, the front end of the screw rod is rotatably connected to the front end of the telescopic chamber, the tail end of the screw rod passes through the nut seat and is connected to the rotating shaft of the servo motor, an injection hose is provided inside the guide rod, the front end of the injection hose passes through the guide rod and is connected to the balloon, the tail end of the injection hose is located inside the handle and is connected to the liquid storage assembly on the handle, a peristaltic pump is provided in the handle, and the peristaltic pump is provided on the injection hose.

[0007] The beneficial effects of the utility model are as follows: by starting the peristaltic pump, the liquid is transported to the balloon through the injection hose, so that the balloon expands and normal tissues are isolated and protected. When the supporting effect of the balloon does not meet the requirements, the servo motor drives the screw rod to rotate, and the nut seat moves linearly in the telescopic cavity, thereby driving the movement of the adjustment sleeve to achieve the purpose of adjusting the exposed part of the balloon. The size of the balloon is adjusted again by supplying or pumping liquid through the peristaltic pump, without manual injection through a syringe, and automatic adjustment of the adjustment sleeve is achieved. The adjustment method is efficient, fast and simple to operate. The peristaltic pump will not come into direct contact with the liquid, and the injection speed is slow, uniform, easy to control, and safer.
