 技术问题
现有的用裂隙灯显微镜联合裂隙灯前置镜检查法检查眼底时，裂隙灯前置镜无法固定，检查医生需要手持裂隙灯前置镜，操作不便，医生无法腾出手来进行其他操作，需要进一步加以改进。
 技术解决方案
一种在检查眼底中使用的支架，其特征是：包括固定在裂隙灯显微镜下巴托调节手轮下方下巴托支架处的固定夹，固定夹通过易弯折的连接管与裂隙灯前置镜夹持器连接。
所述固定夹包括左、右夹体，左、右夹体内侧呈直角形状，与裂隙灯显微镜下巴托调节手轮下方下巴托支架配合，左、右夹体外表面呈圆弧型，左、右夹体两端设置相互嵌合固定的嵌合结构；在左、右直角夹体内侧，设有弹性垫；固定夹上设有与所述连接管一端连接的螺纹孔。
所述裂隙灯前置镜夹持器包括左、右二个将裂隙灯前置镜抱合固定的抱合半环，使裂隙灯前置镜于左、右二个抱合半环形成的圆环中；左、右二个抱合半环通过连接铰链连接，使左、右二个抱合半环能按需要开合；左、右二个抱合半环内衬有增加抱合半环与裂隙灯前置镜的静摩擦力、使抱合更加稳固的弹性垫：左、右二个抱合半环通过嵌合结构嵌合连接固定。
左、右二个抱合半环中一个的基部有基座，基座底面设有与连接件螺纹接头配套的内螺纹孔。
所述弹性垫由下列原料组分制得：NBR3445100份、轻钙粉50份N77450份增塑剂60份、氧化锌6份、防老化剂4010NA1份、发泡剂AC600010份、发泡助剂尿素10份、发泡剂H7份、发泡剂OBSH21份、碳酸钙20份、促进剂10～15份、填充剂25～35份、分散剂1～2份、软化油4～8份、硫磺1.5份。
