Technical Field
The utility model relates to a surgical operation instrument, in particular to an integral supporting sleeve of a sealing ring of a puncture outfit used in laparoscopic surgery.
Background
Laparoscopic surgery is increasingly used, and disposable puncture devices (trocars) are used in laparoscopic surgery in an increasing amount to avoid iatrogenic infections. In the process of frequent passing in and out of surgical instruments, the key for ensuring the smooth operation is to ensure the dynamic tightness of the puncture outfit. Moreover, in the operation process, various surgical instruments in different shapes can be used, so the puncture outfit also needs to be suitable for the surgical instruments in different shapes, the instruments can conveniently enter and exit, and the entering and exiting processes of the instruments need to keep low resistance, thereby ensuring the fluency of the motion process of the instruments.
In the prior art, a general radial seal ring is a funnel-shaped seal ring, and in order to ensure that the seal ring is not punctured by surgical instruments and leakage is caused in a long-time operation process, a seal ring protection plate is usually installed on the upper portion of the funnel-shaped seal ring, so that the instruments move inwards along the surface of the protection plate to pass through the radial seal ring when entering and exiting the puncture outfit. The design of the sealing ring protection plate can reduce the thickness of the sealing ring as much as possible while keeping the sealing performance, thereby reducing the resistance of the sealing ring to the in-and-out of instruments, but in turn, the sealing ring protection plate can increase the movement resistance to the in-and-out of the instruments. Particularly for special-shaped surgical instruments, such as 7-shaped forceps or surgical instruments with convex steps or grooves, the protective sheets in the prior art are embedded in the convex steps or the grooves, and a large resistance is formed when the surgical instruments are inserted or pulled out. Accordingly, there is a need for an improved gasket protection sheet that provides adequate protection to the gasket while further reducing the resistance of the protection sheet to movement of the device in and out.
