本发明涉及医学成像领域，尤其是涉及一种超声探头及含有该超声探头的超声检测装置。
 背景技术
超声成像技术广泛应用在人体组织成像及病理诊断领域。超声检测装置是通过超声波信号对人体进行探测，从而获得人体组织图像的仪器。超声波由超声探头产生及接收，探头对探测效果有决定性的作用。针对不同的成像区域使用不同的超声探头。根据病人年龄、体型以及被扫描组织器官位置不同，探头的尺寸、外形及工作频率也各不相同。
传统的体外医用超声探头一般为非固定式结构，使用时由医生手持，按在被检查者的检测部位，根据图像需要转动、移动或加压超声探头，以获得需要的超声图像。但某些疾病的检查需长时间使超声探头固定在人体的某一个部位，传统非固定式结构的超声探头难以适应，因为医生长时间用手将超声探头固定在人体的某一部位不仅增加劳动强度，浪费人力，而且手持位置难免发生变化，会影响检测效果。

请结合图1、图2和图3，本实施方式的调节组件300包括底座310、弹性调节座320以及调节旋钮330。弹性调节座320设在底座310上，调节旋钮330套设在弹性调节座320上。
请参图3，本实施方式的底座310为圆板状结构，中部开设有可供探测部120穿过的通孔（未标示）。底座310在其开设的通孔的四周设有3个第一限位块312和3个卡接块314。3个第一限位块312和3个卡接块314间隔分布且围绕底座310上通孔的外周均匀分布。第一限位块312的厚度大于卡接块314的厚度。
如图3所示，本实施方式的弹性调节座320由4片弹性夹片322构成。弹性夹片322的一端固定在底座310上通孔的周围，另一端为自由端。弹性夹片322的内壁形状与弹性内衬200的外侧壁形状相匹配，二者可实现无缝抵接，从而4个弹性夹片配合围绕形成一收容弹性内衬200的容置腔324。弹性夹片322的外壁设有外螺纹326。多个弹性夹片322之间设有空隙缺口，但多个弹性夹片322上的外螺纹匹配形成非连续的外螺纹结构。
请结合图1、图2和图3，本实施方式的调节旋钮330为中空的圆柱体结构，内壁设有与弹性调节座320上外螺纹326匹配的内螺纹332，外壁设有便于手握旋转的沿调节旋钮330轴向延伸的条纹334。
当将弹性内衬200组装完毕之后，置于容置腔324内，在弹性调节座320的外周套上调节旋钮330，再将探测部120插入弹性内衬200中，当探测部120深入深度合适之后，旋紧调节旋钮330，通过调节旋钮330挤压弹性调节座320进而挤压弹性内衬200来实现对探测部120的固紧；当需要调节探测部120的深入深度之后，只需要旋松调节旋钮330，将探测部120深入至合适的深度再旋紧调节旋钮330即可，操作简便。
可理解，上述弹性调节座320及调节旋钮330的形状不限于上面所述，如弹性夹片的数量还可以为2片或3片等；弹性调节座320也可以采用弹性材料制作形成的带外螺纹的完整的中空柱体结构；弹性调节座320与调节旋钮330也可以通过其他非螺纹调节方式连接，如可以设置弹性调节座320的厚度（即容置腔324的壁厚）随靠近底座310逐渐增加，调节旋钮330直接套设在弹性调节座320上，当将调节旋钮330向靠近底座310的方向移动时可逐渐增大对弹性调节座320的挤压力从而弹性调节座320弹性挤压弹性内衬200；调节旋钮330上可以不设置条纹334，或者条纹334也不限于上面沿调节旋钮330的轴向分布等；进一步，该弹性调节座320可直接固定在固定件400上而不需要设置底座310。
请结合图2和图3，本实施方式的固定件400为一粘贴板，包括固定部410以及粘贴部420。粘贴部420为采用医用高分子材料（如热塑性聚氨酯弹性体塑料（TPU）等）制作的薄板，用于粘贴固定在目标物体上。粘贴部420的中部开设可供探测部120穿过的通孔。固定部410围绕固定件400上通孔的外周设置，包括3个第二限位块412。3个第二限位块412围绕该通孔均匀分布，中间设有与第一限位块312尺寸适配的缺口。第二限位块412上开设有卡槽414。卡槽414的形状及尺寸与卡接块314的形状及尺寸匹配，从而卡接块314可旋入该卡槽414中，相应地，第一限位块312卡在相邻的两个第二限位块412中间的缺口部位，从而实现固定件400与底座310的卡接。
可以理解，在其他实施方式中，固定件400还可以为其他可固定在目标物体表面的机构，如吸附板等，且固定件400与底座310还可以通过螺纹方式固定连接，或者通过其他的粘接等方式固接，如可以在底座310上设置几个定位块，在固定件400上对应位置开设定位槽，再将底座310的定位块通过粘胶等方式粘贴在定位槽内；且第一限位块312、卡接块314及第二限位块412的数量也不限于上面所述，还可以为其他合适的数量。
上述超声探头10可广泛应用在医学超声检测装置、超声诊断仪、超声监护仪等超声检测装置中，具有可调节探头本体100的超声角度及加压深度的优势，并可将超声探头10固定在目标物体上进行长时间的超声成像，获取的扫描切面与传统的手持探头无异，可广泛应用在需要长时间进行超声连续监测的临床场合。进一步的，本申请中的超声探头还可以增加自动控制系统，对探头的扫描角度和/或加压深度根据需要进行自动调节，如此可使超声监护装置进一步的智能化。本申请的超声检测装置包括前述的超声探头和一般超声设备中具有的控制系统，包括实现扫描、接收、信号处理、显示等的各种功能模块或电路，在此不再赘述。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
