    摘要： A disposable ligator for applying clamping clips to veins, arteries and blood vessels. The ligator comprises a first handle terminating at its forward end in a first jaw and a second jaw and a second handle, both pivotally mounted on the first handle near the forward end thereof. The handles are shiftable between open and closed positions and shift the jaws between open and closed clip-clamping positions. A clip tube containing a plurality of clips and a spring biased feeder shoe to constantly urge the clips forwardly therein is mounted in the first handle. A pusher is mounted in the first handle parallel to the clip tube in a pusher track which extends to the forward ends of the jaws. The pusher is shiftable by the first and second handles between a retracted position when the handles are closed and an extended position to locate a clip in the pusher track at the forward ends of the jaws when the handles are open. The first handle provides a ramp structure leading to the pusher track at the forward end of the clip tube which is covered by the pusher when in its extended position and exposed by the pusher when in its retracted position, thus enabling the forwardmost clip to be transferred to the pusher track in front of the pusher due to the forward urging of the clips in the clip tube, and without the necessity of moving transfer parts.

    摘要： A safety trocar is provided which includes a spring-loaded shield that shields the cutting tip of the obturator after the obturator penetrates tissue. The distal end of the shield is hemispheric in profile and contains slides within cutting tip. The rounded distal end enables the shield to spring forward to shield the cutting tip as soon as the tip perforates the tissue. In other embodiments, positive mechanical means effect shielding.

    摘要： A safety trocar is provided which includes a spring-loaded shield that shields the cutting tip of the obturator after the obturator penetrates tissue. The distal end of the shield is hemispheric in profile and contains slides within cutting tip. The rounded distal end enables the shield to spring forward to shield the cutting tip as soon as the tip perforates the tissue. In other embodiments, positive mechanical means effect shielding. Alternately, the obturator tip is retractable into the cannula or shield, by use of mechanical means such as a spring mechanism.

    摘要翻译： 提供了一种安全套针，其包括弹簧加载的屏蔽件，其在闭孔器穿透组织之后屏蔽封闭器的切割尖端。 屏蔽的远端是半球形的，并在切割尖端内包含滑块。 圆形的远端使得护罩能够弹起向前以在尖端穿孔组织时一直屏蔽切割尖端。 在其他实施例中，正机械装置影响屏蔽。 或者，通过使用诸如弹簧机构的机械装置，闭塞器尖端可缩回插入或屏蔽。
