A pliers includes a first member having a first head and a first handle, and a second member having a second head and a second handle. Each of the handles includes a recessed grip area bounded by a forward lip and a rear lip. The rear lip has a cross-sectional area not greater than a cross-sectional area of a portion of the handle adjacent the rear lip and opposite the grip area. The pliers also includes a first grip positioned on the grip area of the first handle and a second grip positioned on the grip area of the second handle.

A three-dimensional printer includes: a machine mainframe, formed with a carrying plane; a three-dimensional printing module, installed on the machine mainframe, and used for forming a three-dimensional object on the carrying plane according to a three-dimensional model data; and a color spraying nozzle module, installed on the machine mainframe and used for coloring a surface of the three-dimensional object according to the three-dimensional model data, wherein the color spraying nozzle module includes at least one color spraying nozzle and at least one screen member, the color spraying nozzle is formed with at least one nozzle hole, the screen member is formed with at least one screen hole, the screen hole is arranged corresponding to the nozzle hole, and the area of the screen hole is smaller than the area of the nozzle hole thereby enabling the color spraying nozzle module to more efficiently color the three-dimensional object.

A method is used to manufacture an anvil of a surgical circular stapler. The anvil includes a head and a shank extending proximally from the head. The method includes forming the head of a surgical circular stapler using a metal injection molding process. The method also includes forming an annular array of staple forming pockets in the head. The method also includes machining the shank of the surgical circular stapler. The method also includes coupling together the head and the shank of the surgical circular stapler that were separately manufactured.

A pliers includes a first member and a second member pivotally coupled to the first member. The first member and the second member each include a head and a handle having a recessed area with a non-circular cross-sectional shape and an exposed end portion adjacent the recessed area. The recessed area is bounded by a forward lip and a rear lip. The forward lip has a cross-sectional area not greater than a cross-sectional area of a portion of the handle adjacent the forward lip and opposite the recessed area. The pliers also includes a first grip positioned on the recessed area of the handle of the first member and a second grip positioned on the recessed area of the handle of the second member. The end portions of the handles are made of metal.

A method is used to manufacture a frame of a curved surgical stapler. The method includes manufacturing a first portion of the frame of the curved surgical stapler separate from the first portion. The first portion includes a first curvilinear portion of an end effector and a first alignment feature. The method also includes manufacturing a second portion of the frame of the curved surgical stapler. The second portion includes a second alignment feature. The method also includes manufacturing a third portion of the frame of the curved surgical stapler separate from either of the first or second portions. The third portion includes a C-shaped track. The method also includes aligning the first and second portions portion with the second portion by aligning the first and second alignment features. The method also includes coupling the first and second portions of the frame of the curved surgical stapler together.
