The invention provides an eccentric puncture outfit which comprises a first sleeve and a second sleeve, the first sleeve is arranged in the second sleeve in a sleeved mode, an air inlet channel is formed in the first sleeve, and a smoke exhaust channel is formed between the first sleeve and the second sleeve; the first sleeve comprises a first pipe head and a first pipe body which are communicated with each other, the second sleeve comprises a second pipe head and a second pipe body which are communicated with each other, the first pipe head is located in the second pipe head, the first pipe body is located in the second pipe body, and the first pipe body deviates from the center of the first pipe head; the second pipe body deviates from the center of the second pipe head, independent operation of gas injection and smoke exhaust is achieved through the gas inlet channel and the smoke exhaust channel, in addition, an eccentric structure is adopted, the good operation effect can be achieved in the operation scene with the operation space or the operation range limited, and the operation requirements of various angles are met.
Description
technical field [0001] The invention relates to the field of medical instruments, in particular to an eccentric puncturer. Background technique [0002] A trocar is a surgical instrument that pierces the wall of a body cavity and provides a passage for other surgical instruments to enter the body cavity. It belongs to a minimally invasive surgical instrument. The traditional trocar generally includes a sleeve assembly and a trocar needle core. Apply pressure to the trocar, push the tip of the trocar through the skin until the trocar enters the body cavity, withdraw the trocar needle core, and the sleeve assembly can be used as a minimally invasive instrument channel for performing endoscopic surgery and endoscopic inspection operations. Introduction of various instruments and tools into body cavities. [0003] When the electric knife in the puncturer burns or coagulates human tissue, it will produce a lot of smoke and water vapor. On the one hand, the smoke produced by the ...
