摘要： An electrosurgical device for laparoscopic use in tissue dissection and coagulation. The device includes a barrel member having a dissection tip at the distal end thereof that is connected to a source of electrical energy. An insulating sheath member surrounds the barrel member. The sheath member is movable between a first position wherein the distal end thereof extends distally beyond the dissection tip and a second position wherein the dissection tip extends distally beyond the distal end portion of the sheath member. The device includes means to flush and vacuum the surgical site. The device also includes pressure relief means to limit the internal pressure within the device.

摘要： The present invention is directed towards a mechanical morcellator which includes a rotatable and relatively retractable cutting head. User manipulation varies the amount the cutting head extends out of a sheath, the amount of suction communicated to the cutting head, and the operation of a motor which rotatably drives the cutting head. Suction is communicated to the cutting head to aspirate the tissue fragmented by the cutting head. The morcellator is adapted to be inserted through a laparoscopic port site and directly fragment and aspirate tissue from within a patient's body. Alternate embodiments of the present invention provide different cutting head extension and retraction devices. The morcellator of the present invention allows removal of tissue without the need for large entry incisions.
摘要翻译：本发明涉及一种包括可旋转且相对可缩回的切割头的机械旋转器。用户操纵会改变切割头从护套延伸出来的量，传递到切割头的抽吸量以及可旋转地驱动切割头的马达的操作。抽吸被传送到切割头以吸出由切割头分割的组织。旋转器适于通过腹腔镜端口部位插入，并直接从患者体内分离和抽吸组织。本发明的替代实施例提供了不同的切割头延伸和缩回装置。本发明的发明者允许去除组织而不需要大的进入切口。

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。
