摘要： A surgical instrument and a linear stapler. By providing a staple pushing assembly (3) and a variable direction transmission device (6), when a stapling mechanism is closed, the variable direction transmission device (6) drives a first screw (31) in the staple pushing assembly (3) to rotate, so that a firing nut (32) sleeved on the first screw (31) moves in a first axis direction (A) with respect to the first screw (31), and thus staples (23) in a staple cartridge (21) are fired in sequence. Therefore, the use of a sequential stapling manner in the surgical instrument and the linear stapler can save the required firing force, thereby avoiding deformation of an anvil (11), and achieves a good stapling effect, a good suturing effect, and high surgical safety.

摘要： Dual-motor clip applying forceps, comprising an operating head (1), and a first motor (2), a second motor (3), a first driving assembly (4), a second driving assembly (5), and a clip compartment assembly that are provided in the operating head (1). The clip compartment assembly comprises a clip compartment (6) for accommodating a ligature clip and a clip clamp (7) provided on one side of the clip compartment (6). The operating head (1) is further provided with a firing lever (11) and a clip pushing lever (12). The firing lever (11) is connected to the clip clamp (7) to drive the clip clamp (7) to open or fire. The first driving assembly (4) is connected to the firing lever (11) and the first motor (2), and the second driving assembly (5) is connected to the clip pushing lever (12) and the second motor (3). The clip pushing lever (12) pushes the ligature clip within the clip compartment (6) into the clip clamp (7). The dual-motor clip applying forceps solve the problem of conventional clip applying forceps, in which clip feeding and firing movements need to be completed by using a single shaft and have significant dependencies and constraints, which are likely to cause operational errors. The clip applying forceps are controlled by dual motors, thereby simplifying operations, increasing the degree of freedom, and reducing error rates.
