背景技术Background technique
现有通用型模板属于定点式模板，无法改变模板通道的角度和朝向，也就是无法改变入针时的轨迹，当入针轨迹上遇到阻挡物如耻骨等，无法改变其角度，不能准确的到达病灶，使用效果差。以前列腺部位的植入手术为例，手术前将患者体态摆成截石位，根据亚洲人体结构特征，绝大多数男性在该体位下通过设备由会阴区垂直观察体内，但如果前列腺体积过大，其边缘部分会被耻骨遮挡，受现有器械无法调整入针角度所限，不能到达遮挡前列腺部分，通常医生会脱离器械辅助凭借经验徒手入针或依靠器械紧贴住耻骨入针，尽量靠近耻骨后前列腺部分，但实际效果均不理想。The existing general-purpose template is a fixed-point template, which cannot change the angle and orientation of the template channel, that is, it cannot change the trajectory of the needle insertion. Reaching the lesion, the effect is poor. Take the implantation of the prostate as an example. Before the operation, put the patient in the lithotomy position. According to the structural characteristics of the Asian human body, most men can observe the body vertically from the perineal area in this position. However, if the prostate is too large , the edge part will be blocked by the pubic bone, limited by the inability to adjust the needle insertion angle of the existing equipment, and cannot reach the part that covers the prostate gland, usually the doctor will break away from the equipment and rely on experience to insert the needle by hand or rely on the equipment to cling to the pubic bone insertion needle, as close as possible Retropubic prostate, but the actual effect is not ideal.
