Double-lumen catheter side port incision device of bronchial blanking plug

Abstract

The invention relates to a double-lumen catheter side port incision device of a bronchial blanking plug. A linked clamping mechanism comprises a rear slide block, a front slide block, a movable clamp plate and an operating handle, wherein the front slide block and the rear slide block are respectively arranged in guide grooves or guide holes which are positioned on the front part and the rear part of a machine base; at least two push rods are arranged in the guide holes of the machine base and supported against on the guide surface of the rear slide block; the movable clamp plate arranged on the front part of the machine base is connected with the push rods; the operating handle articulated with the machine base is respectively articulated with the front slide block and the rear slide block through a front connecting rod and a rear connecting rod; a blade is arranged between a tool apron and a pressing block and fixed through a fastening screw; the tool apron is adjustably connected with the front slide block; both ends of an adjustment rod and both ends of a guide pillar are respectively connected with the machine base and a positioning plate; an adjustment part positioned at the outer side of the positioning plate is connected with the adjustment rod; and a catheter rod is arranged on the positioning plate and positioned at the rear part of the blade. The double-lumen catheter side port incision device provided by the invention has the advantages of reasonable structure, reliability for positioning and clamping, handiness for operation and capability of enhancing production efficiency and finished product ratio.

Description

technical field [0001] The invention relates to a side hole incision device for a double-lumen catheter of a bronchial occluder, which is used to make a double-lumen catheter for a disposable bronchial occluder assisted by tracheal intubation for lung ventilation or ventilation of a predetermined lung area during chest surgery. It belongs to the technical field of medical equipment. Background technique [0002] The bronchial occluder is used to separate the lungs for ventilation during thoracotomy, and it is used in combination with a tracheal tube. The bronchial occluder is mainly composed of a double-lumen catheter, an endotracheal catheter, a four-way connector, and a balloon installed at the bottom of the double-lumen catheter. The balloon is inflated with gas into the air cavity of the double-lumen catheter, and the balloon is inflated to position the double-lumen catheter so as to block one side of the bronchi. The double-lumen catheter of the bronchial occluder is ...

AI Technical Summary

Problems solved by technology

Due to the circular shape of the double-lumen catheter and the small diameter of the side hole, it is very difficult to make an incision manually on the side hole, and the labor intensity of the operator is high. Either less cutting will cause the wall of the side hole to not be completely removed, or more cutting will cause the The guide wire lumen is cut through, so that the guide wire lumen communicates with the air cavity, so the production efficiency of the side hole incision process is low, and the yield is low, which is the bottleneck problem in the current production of bronchial occluders
