摘要： An endoscopic vessel harvesting device and a method of endoscopic harvesting of vessels from a patients body. The method comprises locating the vessel, and inserting the vessel harvesting device through an incision. Dissecting the vessel from the surrounding tissue, and capturing side branch vessels in a vessel capturing device. Ligating and transecting the side branch vessels using electrodes and a knife located in the vessel capturing device. Finally, ligating and transecting the vessel, and removing the vessel from the patients body. The vessel harvesting device comprises a head piece, a shaft having a lumen for receiving an endoscope, and a vessel capturing device located on the head piece for capturing the side branch vessels in the receiver.

摘要： In accordance with the present invention there is provided a method for suturing tissue using a needle holder device, The device includes a handle for holding it, the handle has distal and proximal ends. The device also has right and left arms extending distally from the handle. The arms of the device have proximal ends attached to the handle and distal ends having grippers attached thereto for gripping and releasing a needle. The device includes at least one mechanism for moving the distal ends of the arms closely adjacent to one another and for passing the needle from one gripper to the other and thereafter for moving the distal ends of the arms further apart from one another. The right gripper is holding a needle having a suture attached thereto. The method first involves moving the distal ends of the arms apart from one another and manually inserting the needle into the tissue and back out again. Thereafter, the method involves actuating the mechanism so as to move the arms closely adjacent one another so that the left gripper holds the needle, the right gripper releases the needle. Then the method involves moving the distal ends of the arms further apart from one another. Lastly, the method involves removing the needle from the tissue.

摘要： An electrosurgical hemostatic instrument including a curved end effector. A preferred embodiment of the invention provides a bipolar endoscopic clamping, coagulation and cutting device. In this device, a substantially straight, axially flexible knife is used to cut tissue grasped by the jaws of the end effector. The end effector includes a knife channel which is wider than the knife. The knife may include sacrificial contact points adapted to contact the walls of the knife channel as the knife moves through the channel, protecting the cutting edges of the knife blade from damage.

摘要： A surgical stapling instrument for performing a circular anastomosis stapling operation is provided. The surgical instrument includes a stapling head assembly mounted by a curved shaft to an actuator handle assembly and incorporates an improved actuator mechanism for transmitting the required operating forces and movements from the actuator handle assembly through the curved shaft to an anvil and staple driver of the stapling head assembly. The stapling head assembly includes a longitudinally movable trocar detachably secured by one or more retainer clips on a hollow shaft of the anvil. When the trocar is retracted, the anvil shaft slides into a central support tube which aligns the anvil axially and circumferentially with a staple holder on the stapling head assembly. The retainer clips are locked against the trocar by the support tube and transmit tension from the trocar to the anvil with no tension load on the anvil shaft. The actuator mechanism permits adjustment of the anvil gap to produce a desired staple height and precludes actuation of the staple head assembly if the anvil gap is set outside of a predetermined range. Also, the actuator mechanism is adapted to both advance and retract the staple driver relative to the staple holder in the stapling head assembly. Further, an improved arrangement for attaching the support shaft to the stapling head assembly and to the actuator handle assembly is provided.
摘要翻译：提供了一种用于执行圆形吻合缝合操作的外科缝合器械。手术器械包括一个装订头组件，该装订头组件通过弯曲的轴安装到致动器手柄组件上并且包括改进的致动器机构，用于将所需的操作力和从致动器手柄组件通过弯曲轴的运动传递到钉子的砧座和缝钉驱动器头组件。缝合头组件包括可由一个或多个保持夹固定在砧座的空心轴上的可纵向移动的套管针。当套管针缩回时，砧座轴滑入中心支撑管，该中心支撑管使砧座轴向和周向与钉在钉头组件上的缝钉保持架对准。保持夹通过支撑管锁定在套针针上，并将张力从套管针传递到砧座，在砧座轴上没有张力负载。致动器机构允许调整砧座间隙以产生期望的钉高度，并且如果砧座间隙设定在预定范围之外，则阻止钉头组件的致动。此外，致动器机构适于相对于缝合头组件中的缝钉保持器使订书钉驱动器前进和缩回。此外，提供了一种用于将支撑轴附接到装订头组件和致动器手柄组件的改进的布置。

摘要： A multiple-load cartridge assembly for use with a linear surgical stapling instrument of the type which, when actuated, simultaneously implants at least one row of staples in the tissue of a patient and forms or clinches the staples of the row against the instrument anvil. The cartridge assembly comprises a cartridge having a row of staple-containing forming pockets and a driver having a plurality of blades equal in number to the number of forming pockets and configured to drive the staples from the forming pockets through the tissue to be sutured and against the instrument anvil to be clinched, when the surgical stapling instrument is actuated. The cartridge has at least one row of storage pockets, equal in number to the forming pockets, and each containing at least one staple. An indexing mechanism is provided to shift the at least one staple in each storage pocket to the line of action between the driver and the anvil after the first actuation of the surgical stapling instrument, for at least another actuation of the surgical stapling instrument. A safety interlock within the cartridge assembly assures correct sequential operation of the cartridge assembly and prevents jamming thereof. An indicator visually shows the number of the load of staples ready to be implanted and formed.

摘要： A medical instrument handle includes a stem, a joystick assembly, and a medical-instrument-member first articulation cable. The stem has a proximal stem portion and a distal stem portion. The joystick assembly includes a platform, a proximal joystick portion and a distal joystick portion, wherein the distal joystick portion is articulatably connected to the proximal stem portion. The first articulation cable includes a proximal cable portion which is connected to the platform and which is substantially transversely constrained by the stem. Articulation of the joystick assembly with respect to the stem changes a distance between the platform and the stem as measured along the first articulation cable. A medical instrument includes a medical instrument handle and a medical end effector. Examples of medical end effectors include, without limitation, a medical grasper and a medical snare.
