一种手触式粒子植入器
摘要：
本实用新型公开了一种手触式粒子植入器，本实用新型包括外保护套、穿刺套管针和导杆，导杆插在穿刺套管针中，外保护套套在穿刺套管针外，外保护套、穿刺套管针和导杆三者相对滑动设置，穿刺套管针上滑动设置有位于外保护套之后的穿刺定位滑块。本实用新型通过穿刺定位滑块预定刺入深度，在进入结直肠时通过保护外套罩住穿刺套管针的针尖，防止扎伤手术者的手指及直肠，当接触到肿瘤时，驱动穿刺套管针插入肿瘤组织内，到达预设定深度，再通过导杆将粒子推入肿瘤组织内，能准确的将粒子植入设定深度，从而可以控制粒子的植入深浅。操作方法简单、使用、安全。
摘要（英）：

The utility model discloses a hand contact type seed implantation device. The hand contact type seed implantation device comprises an outer protection sleeve, a puncture trocar and a guide rod, wherein the guide rod is inserted into the puncture trocar, the puncture trocar is sleeved with the outer protection sleeve, the outer protection sleeve, the puncture trocar and the guide rod slide relatively, and a puncture positioning slide block located behind the outer protection sleeve slides on the puncture trocar. The puncture depth of the puncture positioning slide block is predetermined, so that when the hand contact type seed implantation device is arranged into colorectum, the point of the puncture trocar is covered by the outer protection sleeve, and the fingers of an operator and rectum are prevented from being stabbed; when the hand contact type seed implantation device is in contact with the tumor, the puncture trocar is driven to be inserted into the tumor tissue and reaches the preset depth, then seeds are pushed into the tumor tissue through the guide rod and can be accurately implanted to reach the set depth, and accordingly the implantation depth of the seeds can be controlled. The hand contact type seed implantation device is simple in operation and safe in use.
