Straight seam cutter

Abstract

The invention discloses a linear type suturing and excising device, comprising a body, a staple cartridge rack, a staple anvil, a staple cartridge, a cocking block and a knife pushing rod, wherein the staple cartridge rack, the staple anvil and the staple cartridge are arranged at the far end of the body, the cocking block is used for pushing a staple pushing piece and is arranged in a chute of the staple cartridge, the knife pushing rod pushes the cocking block to move, the staple cartridge rack is provided with a safety block for preventing secondary cocking, the safety block has a linear motion trail, the moving direction of the safety block is vertical to the moving direction of the knife pushing rod, and the safety block is arranged at the far end of the knife pushing rod and the excising knife, and is used for limiting the movement of the knife pushing rod and the excising knife from the near end of the linear suturing and excising device to the far end of the linear suturing and excising device when the linear type suturing and excising device is under the initial state and under the state of cocking completion. The linear type suturing and excising device has the beneficial effects that a doctor is effectively prevented from performing the next operation under the condition of not replacing a cocked staple cartridge, the occurrence of medical negligence is avoided, and the structure is simple and effective.
