Anti-misoperation type cutting stapler

Abstract

The invention discloses an anti-misoperation type cutting stapler which comprises a nail pressing seat, a nail bin, a bracket and a nail pushing device, wherein a plurality of suturing nails are arranged inside the nail bin; the bracket takes a supporting effect on an assembly; the nail pushing device is used for pushing the suturing nails in the nail bin; the nail pushing device comprises a pushing plate, a nail pushing sledge and a nail pushing particle; the nail pushing particle inside the nail bin directly acts on the suturing nails; the nail pushing sledge is initially positioned in an initial position of the nail bin; the front part of the nail pushing sledge pushes the nail pushing particle and a hasp bridged with the front end of the pushing plate is arranged at the rear part of the nail pushing sledge; the rear end of the pushing plate is connected with a sliding block; a locking boss is formed in the front part of the pushing plate; the bracket between the locking boss and the nail pushing sledge is provided with a clamping groove; a pushing plate spring sheet is arranged on a guide block. When the stapler is in an initial state, the pushing plate is pushed forwards, the front end of the pushing plate is bridged with the rear part of the nail pushing sledge, the locking boss passes through the clamping groove, the pushing plate pushes the nail pushing sledge to reach the front end of the nail bin, the nail pushing sledge is clamped by the nail pushing particle to stay at the front end of the nail bin, and the pushing plate is reset backwards; when the pushing plate is pushed again, the pushing plate cannot be bridged with the nail pushing sledge, the pushing plate spring sheet presses down the pushing plate, the locking boss falls into the clamping groove and the pushing plate is locked. The structure can prevent the empty nail bin from being pushed by mistake.

Description

technical field [0001] The invention belongs to the field of medical instruments, and in particular relates to a misoperation-preventing cutting stapler. Background technique [0002] The linear cutting stapler is a commonly used clinical instrument. The instrument has two functions of suturing and cutting. While suturing the wound, the specimen tissue is resected. It generally includes upper and lower jaws, and a closing handle for closing the upper and lower jaws. The nail anvil and the nail bin arranged at the far ends of the upper and lower jaws are relatively arranged in the nail bin and can be opposite to all nail bins at the same time. The staple pushing sled that the staple cartridge moves and the pusher bar that is provided with a cutter at the far end, and the push button used to drive the moving of the nail pushing sled and the pusher bar. Staples are arranged in the staple cartridge, the staple pusher sled sequentially pushes the staple pushers and the staples t...
