Embodiment Construction
[0030] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0031] Such as Figure 7As shown, this embodiment provides a spiral groove for drug delivery, including a spiral assembly and a circular tube 2 for positioning the spiral assembly. The spiral assembly is a plurality of spiral parts stacked in a helical manner with the circular tube 2 as the center Connected in sequence, the spiral piece includes a side vertical plate 3 and several spiral pieces 1, and the spiral piece is bent to form the side vertical plate 3 and the spiral piece 1 after blanking as a whole, and the bottom surface of the spiral piece 1 Bolts 4 are all provided, and a connecting head 5 is provided on one side, and the connecting head 5 of the spiral sheet 1 is provided with an adaptive bending process hole for the bolt 4 of the adjacent spiral sheet 1 to pass through. 1. Form a helical shape around the round tube 2 in turn, a...
