During medieval times, barbers performed surgery on customers, as well as tooth extractions. 在中世纪，理发师为顾客做外科手术，并为顾客拔牙。 The original pole had a brass wash basin at the top (representing the vessel in which leeches were kept) and bottom (representing the basin that received the blood). 原来的柱子上下各有一个黄铜脸盆（上面的表示放水蛭的容器，下面的是盛血的水盆）。 The pole itself represents the staff that the patient gripped during the procedure to encourage blood flow. 杆子本身代表着手术过程中病人紧紧抓着的工作人员，以促进血液流动。 |
