And inserting a surgical instrument into the through hole of the sealing valve, and injecting air into the puncture outfit sleeve, wherein the sealing valve plays a sealing role at the moment. The side wall of the connecting piece is in an arc shape which is inwards concave along the circumferential direction, namely, the connecting piece adopts a necking design, when the surgical instrument is swung at any angle, the surgical instrument drives the necking of the sealing valve to fold, the central point of the sealing valve moves along with the swinging position of the surgical instrument, and the port part of the sealing valve cannot leak air due to pulling deformation, so that the sealing valve is always kept in a sealing state.
Furthermore, an annular clamping groove is formed in the top of the air blocking sealing valve, and a clamping ring matched with the annular clamping groove extends upwards from the top end of the puncture outfit sleeve. The annular clamping groove is matched with the clamping ring for use, the effect of easy disassembly is achieved, and when the choke seal valve or the puncture outfit casing is damaged or aged, the change is convenient.
Further, the mode that sealed lid adopted the joint sets up on the seal receptacle, sealed lid bottom surface downwardly extending is provided with the rand, the annular breach has been seted up to rand lateral wall week, sealed cap card is established in the annular breach.
The utility model has the advantages that: the utility model provides a puncture outfit sealing valve component, simple structure, reasonable design, safe and effective use, through setting up choke seal valve, retainer plate and seal valve at the puncture outfit sleeve pipe top, thus during the operation, after the surgical instruments pass above-mentioned sealing valve component, the sealing valve component contacts with the surgical instruments parcel, play a sealing role; in the operation process of the surgical instrument, the surgical instrument is swung at any angle, the surgical instrument drives the sealing valve to shrink and fold, the central point of the sealing valve moves along with the swinging position of the surgical instrument, air leakage caused by pulling deformation of the opening part of the sealing valve is avoided, and the whole sealing valve is always kept in a sealing state.
