Embodiment approach

[0048] According to one embodiment, the movement means comprise a cartridge movement means 22 adapted to move the staple cartridge 10 distally towards the stationary anvil 11 . Alternatively, an anvil moving device adapted to move the anvil proximally toward the stationary staple cartridge may be provided.

[0049] The staple cartridge moving device 22 includes a guide 23 that enables the staple cartridge 10 to move longitudinally relative to a preferably generally C-shaped support structure 24 of the staple fastening assembly 5, and a first push member (in FIG. hidden in the center) is placed between the staple cartridge 10 and the support structure 24 and is connected to the manual operation member provided at or near the handle 2 through the first motion transmission member and the motion conversion or multiplication mechanism.

[0050] According to one embodiment, the first movement transmitting member comprises a rotation rod or a tension or compression rod received in th...

Abstract

A surgical stapling instrument (1) for laparoscopic manipulation of tissue in a patients body comprises a support shaft (4), a handle (2) connected to a proximal end (3) of the support shaft (4), a staple fastening assembly (5) connected to a distal end (6) of the support shaft (4) and having a curved cartridge (10) and a curved anvil (11) adapted to cooperate with the cartridge (10) for clamping the tissue and forming the ends of staples exiting from the cartridge (10). The support shaft (4) comprises a curved shaft segment (7) formed between a proximal shaft segment (8) and a distal shaft segment (9) so that a longitudinal axis (D-D) of the distal shaft segment (9) and staple fastening assembly (5) is inclined with respect to a longitudinal axis (P-P) of the proximal shaft segment (8).

Description

technical field [0001] The present invention relates to a surgical suturing instrument that can be used in the diagnosis and treatment of all pathologies that are optimally treated, for example, by curved suture resection. Background technique [0002] Curved staplers have proven to be very effective in cutting and stapling tissue with improved visibility and access compared to traditional staplers. The contoured shape of the curved end effector enables better positioning and visualization of the end effector and the tissue to be treated. [0003] Although the known curved staplers are very satisfactory in open surgery, they cannot be used in laparoscopic surgery because their general shape and the size of their instrument shaft and staple fastening assembly make them unsuitable. It may or may be difficult to guide an instrument through a laparoscope access port, such as a trocar port or a hand aid port, to comfortably reach a target site remote from the laparoscope access ...
