摘要： A staple cartridge assembly and a medical anastomat. The staple cartridge assembly comprises: a staple belt (2) and a support member (3), the staple belt (2) comprising a staple belt body (21) which is mounted on one side of the support member (3) and comprises a first surface (211) away from the support member (3); a staple cartridge cover (1), which at least partially covers the first surface (211) of the staple belt body (21) and comprises a second surface (13) opposite the first surface (211) of the staple belt body (21), a first gap (6) being formed between the first surface (211) of the staple belt body (21) and the second surface (13) of the staple cartridge cover (1); and a trigger block (4), which is movably arranged at the bottom of the staple cartridge cover (1) and is movable in an axial direction, wherein the trigger block (4) comprises a staple cutting portion (41), the height (P1) of the highest point of the staple cutting portion (41) being greater than the height (P2) of the first surface (211) of the staple belt body (21). According to the present invention, by means of providing the first gap (6) between the first surface (211) of the staple belt body (21) and the second surface (13) of the staple cartridge cover (1), the staple cutting portion (41) of the trigger block (4) is higher than the first surface (211) of the staple belt (2), which is convenient for the staple cutting portion (41) to drive an anastomosis staple (22) to be separated from the staple belt (2).

摘要： A system and method of variable velocity control of a surgical instrument in a computer-assisted medical device including an end effector located at a distal end of the instrument, an actuator, and drive mechanisms for coupling force or torque from the actuator to the end effector. To perform an operation with the instrument, the computer-assisted medical device sets a velocity set point of the actuator to an initial velocity, monitors force or torque applied by the actuator, reduces the velocity set point when the applied force or torque is above a first threshold, increases the velocity set point when the applied force or torque is below a second threshold, decreases the velocity set point to zero when the applied force or torque is above a maximum threshold, and drives the actuator based on the velocity set point. The first and second thresholds are lower than the maximum threshold.

摘要： A surgical instrument, comprising an elongated body assembly (100) adapted for being attached with a loading unit (200), wherein the loading unit may have various types. The elongated body assembly (100) is provided with a loading unit type recognition portion (100a) comprising: a first sliding member (101), configured for being actuated by the loading unit (200) during assembling of the loading unit, so as to be moved to a predetermined position; a first trigger member (102) arranged on the first sliding member (101); a first circuit board (103), the first circuit board (103) being provided with at least two first response members (104), and each first response member (104) being configured to cooperate with the first trigger member (102) to conduct or cut off one first electrical branch (A1), and each of the first electrical branches (A1) may have a different load value; and a controller configured to determine the type of the loading unit (200) according to a feedback signal from the first circuit board (103).
