Title: SEALING FILM CONTAINING GROOVE AND ASSEMBLY
Abstract:
Provided are a sealing film (130) containing a groove (140) and an assembly (100, 200). The sealing film (130) comprises a proximal opening (132), a distal hole (133) and a sealing wall (135) extending from the distal hole (133) to the proximal opening (132). The sealing wall (135) comprises a proximal end face and a distal end face. The distal hole (133) is formed by a sealing lip (134) for receiving an inserted instrument and forming a seal; The sealing wall (135) comprises a body rotatable wall (138) and a plurality of grooves (140). The grooves (140) are recessed from a proximal end face toward a distal end face of the body rotatable wall (138). And an openings of the grooves (140) face the proximal end face, each groove (140) comprising two side walls (142). The grooves (140) extend laterally and outwardly from the sealing lip (134), and a depth of the groove gradually increases. The sealing wall (135) also includes a flange (136) and a plurality of sloping walls (143) extending from the flange (136) and intersecting with the sidewalls (142) of the grooves (140). Wall thickness of the main body rotatable wall (138) and the groove (140) are overall uniformed. Since the grooves (140) have functions of increasing circumferential length, improving lubrication reliability, increasing axial tensile rigidity and the like, friction resistance and the stick-slip can be greatly reduced.
