具体实施方式
本发明的提供的实施方式中，在环形支架上设置调节组件，调节组件的按压部在伸缩部的驱动下，可改变其位置，进而改变环形支架适配的直径，提高架体的通用性，以下进行具体说明。
图1为本发明实施方式提供的架体的结构示意图。如图1所示，架体包括环形支架1和调节组件2；环形支架1用于套设在体内超声探头上；调节组件2包括按压部20和伸缩部21，按压部20设于环形支架1内，伸缩部21第一端与按压部20连接，第二端穿出环形支架1，从而位于环形支架1外；伸缩部21驱动按压部20在环形支架1径向方向的第一位置和第二位置之间移动，从而使按压部20与环形支架1的内壁夹紧体内超声探头的外壁。
伸缩部21驱动按压部20到达指定位置后，伸缩部21可保持按压部20在此位置固定不变，按压部20沿环形支架1的径向方向移动，可改变环形支架1的适配尺寸，按压部20在第一位置时，环形支架1的直径最大，按压部20在第二位置时，环形支架1的直径最小，环形支架1能适范围为最大直径和最小直径之间的任意尺寸，使用时，先将环形支架1套设在超声探头的外壁，之后，在适用性的调整按压部20的位置，使按压部20压紧超声探头的外壁，从而到达环形支架1和超声探头相对固定的目的。
图2为本发明实施方式提供的架体的剖视图。如图1和图2所示，按压部20为垫片201，垫片201的第一板面为弧形表面2011，第二板面与伸缩部21连接。使用时，垫片201抵接在超声探头保持部的表面，超声探头保持部的形状一般为圆柱状，因此，将垫片201的第一板面设置为弧形，其与超声探头的外壁之间具有更高的贴合度，进而提高环形支架1与超声探头连接的稳定性。进一步地，在第一板面上设置摩擦垫，摩擦垫采 用如橡胶等柔性材质制成，可进一步提高垫片201与超声探头之间的摩擦力，使架体与超声探头的连接更加稳定。
本方实施方式中，环形支架1的内壁上设有凹槽122，垫片201位于第一位置时，垫片201置于凹槽122内，并且垫片201上的弧形表面2011与环形支架1的内壁形成连续的环形面，此状态下，垫片201和环形支架1形成一个完整的环形结构，该环形结构的表面是连续的，其与所连接的超声探头的外壁具有更高的贴合度，从而使两者连接的更加稳定。
图3为本发明实施方式提供的架体中旋钮处的结构示意图。如图1至图3所示，伸缩部21包括螺杆211和旋钮212；螺杆211的第一端与垫片201的第二板面垂直连接，环形支架1上设有通孔121，螺杆211的第二端穿过通孔121，从而位于环形支架1外；旋钮212与螺杆211螺纹连接，旋钮212位于环形支架1外。伸缩部21采用螺纹连接实现伸缩移动，使用时，旋钮212自转驱动螺杆211沿其轴线方向移动，螺杆211带动垫片201同步移动，从而驱动垫片201沿环形支架1的径向方向移动。
本发明实施方式中，旋钮212包括连接柱2121，连接柱2121上沿其轴向设有贯通的螺纹孔2122；连接柱2121的侧壁123设有周向设置的第一环形凸起2123和第二环形凸起2124，第一环形凸起2123和第二环形凸起2124沿连接柱2121轴向间隔设置；环形支架1的外壁上设有凸起的侧壁123，侧壁123和环形支架1的外壁围成卡槽，通孔121设于卡槽内，侧壁123远离环形支架1的一端设有限位挡板124；第二环形凸起2124卡接于卡槽内，限位挡板124卡接于第一环形凸起2123和第二环形凸起2124之间的间隔内。旋钮212在卡槽内自转，从而驱动螺杆211直线运动，限位挡板124抵接在第二环形凸起2124的一侧，当垫片201达到指定位置后，限位挡板124限制旋钮212沿螺杆211轴线方向移动，进而可保持垫片201在所调节的位置固定不动。优选地，侧壁123和环形支架1的外壁围成半圆形卡槽，半圆形卡槽包括插入口；第二环形凸起2124沿插入口卡接入半圆形卡槽内，并且，第二环形凸起2124与半圆形卡槽卡接时， 半圆形卡槽的圆心、通孔121的圆心和螺杆211的轴心重合。，在进行旋钮212的拆装操作时，第二环形凸起2124沿插入口卡入卡槽内即可，操作简单快捷。
第一环形凸起2123的周面上设有防滑纹，以及第一环形凸起2123远离第二环形凸起2124的一侧设有指示标签。对旋钮212进行操作时，防滑纹可增大旋钮212与手指之间的摩擦力，利于调节操作；指示标签起提示作用，方便对旋钮212进行操作，例如指示标签为旋转方向指示。
图4为本发明实施方式提供的架体中螺杆211处的俯视图。如图2至图4所示，螺杆211的周面上设有沿螺杆211轴向设置的限位平面2111；通孔121上设有与限位平面2111贴合的挡块1211，两者连接时，必须将限位平面2111和挡块1211对齐，才可将螺杆211连接到通孔121内，本实施方式中，螺杆211非圆柱形，通孔121非圆形，无法实现自由转动，进而可避免垫片201自转。
本发明实施方式中，环形支架1包括对称的上支架11和下支架12，调节组件2设于下支架12，下支架12用于连接穿刺支架；上支架11和下支架12的第一端转动连接，第二端卡接，其中，分体结构的环形支架1更利于与超声探头连接。
图5为本发明实施方式提供的体内超声探头穿刺支架的机构示意图。如图5所示，体内超声探头穿刺支架包括上述架体，以及架体上连接的穿针结构3。图6为本发明实施方式提供的体内超声探头穿刺支架的使用状态图。如图6所示，使用时，先将环形支架1套接在体内超声探头4的保持部41上，如果环形支架1的内径大于保持部41的外径，两者未连接稳定，从而可会产生相对位移，因此，需要进一步对体内超声探头4进行固定。此时，手动旋拧旋钮，旋钮驱动螺杆转动，垫片沿环形支架1径向移动，压紧在体内超声探头4的保持部41的外表面，进而实现环形支架1和体内超声探头4的固定连接。
此结构的架体，具有较高的通用性，可适配多种尺寸的超声探头，无需针对每种超声探头独立设计适配的穿刺支架，进而降低了穿刺支架的生产成本和使用成本。
上述具体实施方式，并不构成对本发明保护范围的限制。本领域技术人员应该明白的是，取决于设计要求和其他因素，可以发生各种各样的修改、组合、子组合和替代。任何在本发明的精神和原则之内所作的修改、等同替换和改进等，均应包含在本发明保护范围之内。
