本方案的超声换能单元300具有发射面310，所述发射面310形成有位于所述治疗窗111外侧的多个聚焦点，多个所述聚焦点汇聚成一聚焦区400。该聚焦区400可对应多个深度，以使得超声换能单元300具有多个深度的治疗效果。因此，该超声换能单元300可以同时进入到人体皮下组织的不同深度范围，当超声波治疗头10工作时，超声波治疗头10可以同时对人体皮下组织内不同深度的部位发生作用，起到治疗的目的，进一步满足客户不同的需求。
在一实施例中，所述聚焦区400的深度范围为0.5 mm~2.5 mm。具体地，超声换能单元300进入人体皮下组织的深度范围可以是0.5 mm~2.5 mm，该深度为人体的真皮层，当超声波治疗头10工作时，超声波治疗头10可以引起机械效应和热效应，导致胶原蛋白的即刻收缩，引起炎症效应，促进胶原蛋白新生，在该深度范围内，超声波治疗头10主要用于皮肤紧致和皱纹的治疗等。
在一实施例中，所述聚焦区400的深度范围为1.5 mm~3.5 mm。具体地，超声换能单元300进入人体皮下组织的深度范围也可以是1.5 mm~3.5 mm，该深度为人体的皮下脂肪层，当超声波治疗头10工作时，超声波治疗头10可以灭活脂肪细胞，引起脂肪干细胞的分化，分化成纤维细胞，促进组织的紧致和致密，在该深度范围内，超声波治疗头10主要用于治疗萎缩性瘢痕，肥胖等临床问题。
