摘要： A full thickness resection device comprises a control handle including an actuator wherein, when the device is in an operative position within a body lumen of a patient, the control handle remains outside the patient's body and a working head assembly coupled to a control handle by a flexible sheath, wherein, when the device is in the operative position; the working head assembly is located within a body lumen of the patient adjacent to a portion of tissue to be treated, the working head assembly including a tissue stapling mechanism including first and second tissue stapling members moveable relative to one another in combination with a first cable extending from the actuator through the flexible sheath to the first tissue stapling member so that, when the actuator is operated to draw the first cable proximally from the sheath, the first tissue stapling member is moved in a first direction relative to the second tissue stapling member.

摘要： Boring apparatus for forming a generally horizontal underground passage in soil for a utility conduit or the like that includes a tool head with a base portion and a nose portion mounted on the base portion. The base portion is rotatable relative to the nose portion between a first position in which nose portion surfaces are symmetrical with respect to the tool axis so that the tool will move along a straight path and a second position in which nose portion surfaces are in asymmetrical position with respect to the tool axis so that said tool will move along a curved path. By application of torque to the base portion, the base portion is shifted relative to the nose portion to shift the tool head from between an asymmetrical configuration and symmetrical configuration. Torque generating surface structure interacts with the soil and generates clockwise torque in one tool head position and counter clockwise torque in the other tool head position.

摘要： This invention is a new device for installing press fit couplings to join steel pipelines. This apparatus is a joining press which fits inside the pipes to be joined and grabs them on their inside surfaces. It then pulls the pipes together, forcing the pipe ends into the coupling. The invention is comprised of two hydraulically operated grippers to grip the pipe and a hydraulically operated cylinder to pull the pipes together. The entire press is controlled using only two hydraulic lines. The grippers can be retracted and the apparatus moved within the pipeline from one joint to the next.

摘要： Tool for slitting and laterally expanding underground steel gas mains and inserting replacement plastic piping into the spread apart pipeline has a forward end cylindrical portion mounting a single, rearwardly angled blade to make only one line of cut, and a conical pipe spreader portion at its rearward end. The conical spreader portion is eccentrically disposed with respect to the forward end cylindrical portion. A single roller type pipe slitter aligned with the fixed blade may be mounted on a removable extension of the forward end cylindrical portion, to initially groove and weaken the pipe along the intended line of cut. A pneumatically operated impact ram is attached to the rearward end of the tool, as is the leading end of the replacement piping. A wire cable pulls the tool through the underground pipe, thereby grooving, slitting and laterally expanding the pipe. The spacing of the roller slitter in advance of the fixed knife blade is dimensionally related to the length of any coupling or clamp as may be anticipated along the line of cut, and the spacing distance of the fixed knife blade forwardly of the conical spreader portion is related to the cone angle of the latter to increase hoop tension immediately in front of the fixed blade as the cutting proceeds.
摘要翻译：用于切割和横向扩展地下钢管燃气管道的工具并将更换的塑料管道插入扩展的管道中具有前端圆柱形部分，其安装单个向后倾斜的叶片以仅形成一条切割线，并且在其后方形成锥形管扩展部分结束。圆锥形吊具部分相对于前端圆柱形部分偏心地设置。与固定刀片对准的单个辊式管道分切机可以安装在前端圆柱形部分的可移除的延伸部上，以沿着预定的切割线开始凹槽和减弱管道。气动冲击冲头连接到工具的后端，替换管道的前端也是如此。线缆通过地下管道拉动工具，从而开槽，切割和横向膨胀管道。固定刀片之前的滚筒分切机的间距与沿着切割线所预期的任何联接器或夹具的长度尺寸上有关，并且固定刀片在锥形扩张器部分向前的间隔距离是与后者的锥角相关，以在切割进行时立即增加固定刀片前方的箍紧力。
