Abstract

The invention relates to the technical field of medical instruments, and discloses a pushing device and a steam ablation instrument. The pushing device of the present invention comprises a box body, a clamping device, a driving device and a controller. The clamping device is arranged on the side wall of the box body. The driving device comprises a pushing base, a lead screw and a servo motor. The servo motor and the pushing base are arranged on a fixed support in the box body. The servo motor is connected with the lead screw, and the lead screw is connected with the pushing base. The pushing device is used for the steam ablation instrument. The clamping device vertically clamps an injector, so that the air in the injector moves upwards to an outlet of the injector. A plunger of the injector is pushed, so that the air overflows from the outlet of the injector. The controller controls rotation of the lead screw through the servo motor so as to drive the pushing base to push the plunger of the injector in the vertical direction. Liquid in the injector is accurately output to a steam generation device of the steam ablation instrument, thereby ensuring accurate output of the liquid.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of medical devices, and in particular to a pushing device and a steam ablation device. Background technique [0002] Steam ablation is an emerging non-implantable endoscopic interventional technology. It uses an endoscope to send a steam catheter into the lesion of the human organ, and the steam acts on the diseased tissue of the human body through the catheter to repair the organ function of the human body. . [0003] The existing steam ablation equipment mainly includes: a fixing device, a steam generating device and a catheter. The syringe is horizontally fixed on the fixing device. One end of the steam generating device is connected to the outlet of the syringe, and the other end is connected to the input end of the catheter. The liquid inside is transported to the steam generating device, and the steam generating device converts the input liquid into steam, and sends the steam...
