Embodiment Construction

[0043] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0044] see figure 1 , showing a schematic diagram of a surgical cutting and stapling instrument. As shown, the surgical cutting and suturing instrument 1 generally mainly includes a handle 2, a trigger 3, an elongated body 4 and a clamp 5, wherein the trigger 3 is arranged on the handle 2, and the elongated body 4 is from the handle 2 to the distal end (herein The direction close to the handle is called the proximal end, and the direction away from the handle, the end of the elongated body is called the distal end). A clamp 5 is provided at the distal end of the elongated body 4 .

[0045] One clamp arm of the clamp 5 is provided with a staple cartridge 51 , and the other clamp arm of the clamp 5 is provided with a nail anvil 52 . The staple cartridge 51 and the staple anvil 52 are arranged oppositely, and can be closed / opened relatively. ...

Abstract

The invention discloses an operation cutting suture instrument. The operation cutting suture instrument comprises a hand shank, a trigger, a slender body, a drive device, a drive worm, a transmission part, and an execution part, wherein the slender body extends from the hand shank to a far end, the drive device comprises a drive worm gear, the drive worm gear is connected with the trigger and is driven through the trigger, the drive worm is meshed with the drive worm gear and is driven through the drive worm gear, the execution part and the transmission part form lead screw connection, the drive worm gear drives the drive worm to rotate along a first direction to cause the fact that the drive worm and the transmission part are meshed with each other, so that the transmission part is driven to rotate, and therefore through the lead screw connection, the execution part is driven to move in a flat mode to the far end. The operation cutting suture instrument can enable transmission of drive force to be stable, and conveniently provides larger reset force.

Description

technical field [0001] The invention relates to the field of surgical instruments, in particular to surgical cutting and suturing instruments. Background technique [0002] Surgical cutting and suturing instruments are widely used in surgical operations at present. Usual surgical cutting and suturing instruments mainly include handles, clamps and cutting knives, wherein the two clamp arms of the clamps are respectively provided with opposite staple bins and nail anvils, the staple bins contain staples, and the handle is provided with a drive device. When working, the clamps are used to clamp the tissue first, and then driven by the driving device, the staple pusher in the staple magazine pushes the staples towards the anvil, and the staples pass through the tissue and are formed with the cooperation of the anvil to complete The tissue is sutured, so as to realize the firing and suturing of the staples; at the same time, the driving device drives the cutting knife to cut th...
