Embodiment approach

[0037] According to one embodiment, the step of applying the distal portion 3 of the traction member 2 to the target tissue 1 and / or the step of applying traction on the traction member 2 is performed under the control of the visualization device 14 . Specifically, in the step of applying the distal portion 3 of the traction member 2 to the target tissue 1 and / or in the step of applying traction on the traction member 2, a portion of the silk or suture 13 extends through the visualization device 14 ( FIG. 10 and Figure 19 ), wherein the proximal end of the wire or suture 13 protrudes from the proximal end of the visualization device 14, and the distal end 12 of the wire or suture 13 protrudes from the distal end 15 of the visualization device 14.

[0038] According to a different embodiment of the present invention (not shown in the figures), in the step of applying the distal portion 3 of the traction member 2 to the target tissue 1 and / or in the step of applying traction on...

Abstract

The present invention discloses a surgical device for endoluminally or laparoscopically grasping and excising a target tissue (1) sample from areas in a patient's body comprises a surgical stapling device (4) having a distal staple fastening assembly (5) connected via one or more flexible force transmitters (25) to a proximal handle, wherein the staple fastening assembly (5) comprises a cartridge device (8) containing one or more curved open rows of staples as well as a knife, a curved anvil (7) having a staple forming face adapted to cooperate with the cartridge device (8) to form the ends of the staples expelled from the cartridge device (8). The anvil (7) is movable with respect to the cartridge device (8) along a longitudinal axis (L) of the staple fastening assembly (5) and the staple fastening assembly (5) is curved about the longitudinal axis (L). A lateral end of the anvil (7) and a corresponding lateral end of the cartridge device (8) are connected by a longitudinally extending lateral shaft (9) so that a substantially C shaped frame is formed which defines a window (6) for receiving the target tissue (1) and a lateral opening (10) opposite the lateral shaft (9) configured to provide lateral access to the window (6).

Description

technical field [0001] The present invention relates to methods and devices for endoluminally or laparoscopically capturing and resecting tissue samples from regions within a patient's body. More specifically, the present invention relates to a method suitable for covering the lower and upper portions of the gastrointestinal tract, laparoscopic surgery and more advanced transgastric, transvaginal or transanal / rectal procedures. Background technique [0002] There is a great need for methods and instruments for endoluminally or laparoscopically resecting tissue samples from regions within a patient to allow safe and effective removal of tissue samples, such as lesions. In particular, there is a need for a method and instrument for resecting a defined and precise amount of tissue and allowing better control of the field of view during each step of the method. [0003] It is known to grab and excise tissue samples by conventional open surgery. The disadvantages of traditional...
