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： A computer-based apparatus, including: a memory element storing computer readable instructions; a processor; and a source element to expel a first plurality of drops of a substance with a known density through a medium, and under a set of conditions. The processor executes the computer readable instructions to calculate uncalibrated volumes for the first plurality of drops using respective images of drops in the first plurality of drops. The source element expels a second plurality of drops of the first substance through the medium, and under the first conditions. The processor executes the computer readable instructions to: calculate, using a weight for the second plurality of drops and the known density, actual volumes for the second plurality of drops; and generate, using uncalibrated volumes and the actual volumes, an equation to modify the uncalibrated volumes to match the actual volumes.
