    • Medical instrument for implantation of radioactive seeds in a body, the instrument including an elongated support rod and an elongated stylet rod spaced apart from and parallel to the support rod, and being held in that relationship by a stop block and a slide block spaced apart from each other and longitudinally slidable with respect to both the support rod and the stylet rod. The stop block is attached to the support rod and the slide block is clampable to each of the support rod and the stylet rod. A seed cartridge with transverse spaced passageways and a central longitudinal through bore receives, stores, and discharges a plug of spaced radio-active seeds by the stylet rod through a connectible hollow elongated implantation needle through which the plug may be implanted in body tissue.
    • 用于将放射性种子植入体内的医疗仪器,仪器包括细长的支撑杆和与支撑杆间隔开并平行于支撑杆的细长的探针杆,并且通过止动块和与其相隔的滑动块保持在该关系中 彼此相对于支撑杆和通孔针两者可纵向滑动。 止动块连接到支撑杆上,并且滑动块可夹紧到每个支撑杆和通孔针杆上。 具有横向隔开的通道和中心纵向通孔的种子筒通过通孔针通过可连接的中空细长植入针接收,储存和排出间隔开的放射性活性种子的塞子,通过该连接的中空细长植入针将插塞植入体内组织。
