Anti-injury chest puncture device

Abstract

The invention discloses an anti-injury chest puncture device. The device comprises a puncture needle body and a protection plate used in cooperation with the puncture needle body. The puncture needlebody comprises a needle base, a stop ring and a needle tube. The needle tube is fixedly connected to the bottom of the needle base. The top of the needle tube penetrates through the needle base and iscommunicated with the needle base. The stop ring is rotationally connected to the bottom of the needle base. The protection plate comprises an upper panel, an adjusting table and a lower liner. A needle hole running through the lower liner is formed in the surface of the upper panel. The adjusting table is slidably connected to the surface of the upper panel and is in a wedge shape, and needle grooves are formed longitudinally in the surface of the adjusting table. Wing plates are fixedly symmetrically connected to the two sides of the adjusting table. Locking bolts penetrating through the upper panel are arranged on the surfaces of the wing plates. According to the anti-injury chest puncture device, owing to the protection plate with the wedge-shaped adjusting table and the puncture needle body provided with the stop ring, puncture operation can be conveniently conducted by a doctor with insufficient experience, and injuries, caused by faults in operation, to patients are effectivelyavoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a thoracentesis injury prevention device. Background technique [0002] Thoracentesis is one of the most commonly used diagnostic and therapeutic techniques in thoracic surgery. It treats unilateral or bilateral pneumothorax, hemothorax, or hemopneumothorax through suction, fluid extraction, and pleural cavity decompression. [0003] At present, in the process of clinical thoracentesis, the phenomenon of lung injury often occurs, especially when there is less pleural effusion or encapsulated effusion, the above phenomenon is more likely to occur, and the requirements for the doctor's operating experience are relatively high, which increases the doctor's operation. Difficulty, and interns or junior physicians cannot quickly master it, which is likely to cause harm to patients. For this reason, need to design a kind of new technical scheme to give solution.
