20140103094 | LINEAR SURGICAL STAPLER WITH ROTATABLE OPERATION BUTTON - A linear surgical stapler includes upper and lower jaws, an anvil and a cartridge respectively mounted on opposite far ends of the upper and lower jaws, a handle portion, a slider, and a button base relatively fixed to the slider. The lower jaw therein includes a staple drive bar and a cutter pusher. The slider is mounted with the button base. Each lateral side of the button base is pivotally associated with an operation button which is rotatable between a first status where an operating surface of the operation button is perpendicular to an axis of the linear surgical stapler, and a second status where the operating surface of the operation button is parallel to the axis of the linear surgical stapler. Since the operation buttons can be simultaneously collapsed adjacent to the jaws, the profile of the whole instrument and the packaging costs can be reduced. | 04-17-2014 |
20130327808 | STAPLE CHAMBER ASSEMBLY AND LINEAR SURGICAL STITCHING DEVICE USING SAID STAPLE CHAMBER ASSEMBLY - 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. | 12-12-2013 |
