摘要： A linear cutting stapler comprises: an upper jaw and a lower jaw (5) capable of closing or opening relative to each other. A staple cartridge (51) is disposed at a distal end of the lower jaw (5). The lower jaw (5) is U-shaped, and has a staple driving rod (3) and a blade driving rod (4) slidably disposed therein. The linear cutting stapler further comprises a safety mechanism. The safety mechanism comprises an engagement member. A notch fitting the engagement member is disposed on a bottom surface of the staple driving rod (3). The safety mechanism further comprises a floating block (1). The floating block (1) may perform longitudinal displacement in the lower jaw (5). When the floating block (1) is pressed against the staple cartridge (51) or an anvil (6), a top end of the engagement member is driven to perform longitudinal displacement, so that the engagement member is separated from the notch. The linear cutting stapler has a simple structure, is easy to be fabricated, and is safe and reliable.

摘要： A linear cutting stapler includes an upper jaw and a lower jaw capable of closing or opening relative to each other. A staple cartridge is disposed at a distal end of the lower jaw. The lower jaw is U-shaped, and has a staple driving rod and a blade driving rod slidably disposed therein. The linear cutting stapler further includes a safety mechanism which includes an engagement member. A notch fitting the engagement member is disposed on a bottom surface of the staple driving rod. The safety mechanism further includes a floating block which is displaceable in the lower jaw in an up-down direction perpendicular to the length direction of the lower jaw. When the floating block is pressed against the staple cartridge or an anvil, a top end of the engagement member is driven to displace in the up-down direction, thus the engagement member is separated from the notch.

摘要： A linear surgical stapler includes an upper staple cartridge receiving half-section, a lower staple cartridge receiving half-section and a staple cartridge assembly. The staple cartridge assembly includes a cutting groove in which a reciprocating movement cutter is mounted. The cutter includes a bottom surface and a knife blade located at a far end of the cutter. The staple cartridge assembly includes a restricting member mounted therein and an elastic stopper. The elastic stopper abuts against the restricting member when the staple cartridge assembly is in an initial state. The restricting member breaks away from the staple cartridge assembly when the staple cartridge assembly is in a firing complete state, thereby preventing the cutter from sliding towards the far end of the staple cartridge. As a result, misfiring throughout the whole operation of the linear surgical stapler is prevented.
摘要翻译：线性外科缝合器包括接收半部分的上部钉仓，下部钉仓接收半部分和钉仓组件。钉仓组件包括其中安装有往复运动切割器的切割槽。切割器包括位于切割器远端的底面和刀片。钉仓组件包括安装在其中的限制构件和弹性塞子。当钉仓组件处于初始状态时，弹性止动件抵靠限制构件。当钉仓组件处于点火完成状态时，限制构件脱离钉仓组件，从而防止刀具朝向钉仓的远端滑动。结果，可以防止线性外科缝合器整个操作过程中的点火不足。

摘要： An introducer accessory for being fitted with a circular stapler is disclosed, and pertains to the technical field of medical instrument. The introducer accessory at least comprises a sleeve portion sleeved around a distal end of the circular stapler and an introducing portion disposed at a distal end of the sleeve portion. And the introducing portion comprises a spiral member in a conical shape with a cavity and a traction member, the traction member extends in the cavity of spiral member to connect with the distal end of the spiral member such that when the traction member is pulled by an external force, the distal end of the spiral member is pulled out by the traction member through the cavity which causes the spiral member to be unwound internally and finally to form a strip body to withdraw through the circular stapler. Thus, the withdrawing process of introducer accessory can avoid injury to patient during surgery.
