Abstract

The invention discloses a sleeve component, which comprises a sleeve and a jacket which are relatively fixed, wherein an air pipe is arranged on the sleeve and comprises an air hole for ventilation; the sleeve component is characterized in that: an air joint is sleeved at the periphery of the air pipe, comprises a circular hole which can be connected with an air source, and can rotate relative to the air pipe; and a communicating and disconnecting mechanism for communicating or disconnecting the air hole and the circular hole is arranged between the air joint and the air pipe. The sleeve component is used for a structure of a rotary handle for communicating or disconnecting the air source and is more rationally positioned in comparison with the prior art, so that a doctor cannot touch the sleeve component during operation; and thus, the danger of air leakage during the operation is avoided, safety factor is improved, and the sleeve component can be widely applied to a puncture outfit.

Description

technical field [0001] The invention relates to a puncture device, in particular to a sleeve assembly of the puncture device, and belongs to the technical field of medical instruments. Background technique [0002] A trocar is a surgical instrument that pierces the abdominal wall and provides a passage for other surgical instruments to enter the body cavity, and belongs to a minimally invasive surgical instrument. [0003] A trocar usually includes a sleeve assembly serving as an access channel for other surgical instruments and a puncture rod penetrating through the sleeve assembly. To penetrate the skin, the epidermis of the skin is first cut with a scalpel, and then the puncture rod penetrates the skin and enters the body cavity. By applying pressure to the proximal end of the lancet, the tip of the lancet is pushed through the skin until it enters the body cavity. After the puncture device enters the body cavity, the puncture rod is drawn out, and the sleeve assembly c...
