The utility model relates to a needle holder for vascular surgery, which comprises an inverted L-shaped fixing plate, one side of the upper end of the fixing plate is provided with a fixing clamp body, the other side is articulated with a movable clamp body, the fixing clamp body and the movable clamp body are both provided with a clamping part, the lower end of the movable clamp body is articulated with a connecting block, and the lower end of the connecting block is connected with each other. The lower end of the reset spring is sleeved in the fixed sleeve fixed on the fixed plate. The upper end of the fixed sleeve is opened and the lower end is closed. The connecting block is also connected with a pull line passing through the reset spring and the fixed sleeve. The lower end of the pull line is provided with a fixed ring. The lower end of the fixed plate is connected with a handgrip rod, and the handgrip rod is provided with and fixed. The fixed pin matching the inner diameter of the ring has the advantages of simple structure and convenient operation. By hanging the fixed ring on the fixed pin, the clamping force and the clamping state can be ensured, and the drop of the surgical needle can be effectively prevented, thus avoiding the need for the medical staff to hold the hand firmly throughout the suture process and reducing the labor intensity.

一种血管外科用持针钳
本技术涉及医疗设备领域,具体是一种血管外科用持针钳。
技术介绍
持针钳也叫持针器。主要用于夹持缝针缝合各种组织。有时也用于器械打结。外科医生在进行手术的过程中,往往需要将手术所使用的手术针进行拿持。现有大都采用的是一般的持针钳,手握持针钳将手术使用的针夹持住。然而,这种持针钳需要不停地握住钳柄,否则手术用的针就会脱落,不利于手术的进行,也给医务人员增加了劳动量。
技术实现思路
针对上述不足,本技术的目的在于,提供一种保证夹持力和夹持状态,有效防止手术针掉落,避免了缝合过程中需要医护人员手部始终用力紧握,降低了劳动强度的血管外科用持针钳。为实现上述目的,本技术提供以下技术方案:一种血管外科用持针钳,包括倒L型固定板,固定板上端一侧设置有固定夹持体,固定板上端另一侧铰接连接有活动夹持体,固定夹持体和活动夹持体相对的面上均设置有夹持部,活动夹持体下端铰接连接有连接块,连接块下端连接有复位弹簧,复位弹簧下端套设于固定在固定板上的固定套内,固定套上端开口、下端封闭设置,连接块还连接有从复位弹簧和固定套内穿过的拉线,拉线下端设置有固定环,固定板下端连接有手握杆, ...
