A washpipe assembly is described for a passage of pressurized drilling fluid from a stationary first conduit member to a rotating second conduit member. The washpipe assembly comprises a lower union secured to the rotating second conduit member, an upper union secured to the stationary first conduit member, a floating seal assembly attached to the upper union, a rotating seal ring attached to the lower union, and a stationary seal ring attached to the floating seal assembly. The washpipe assembly also includes a washpipe suspended inside the upper union and the floating seal assembly through a waveform snap ring.

Washpipe assembly

A handle for an electric surgical stapler. The electric surgical stapler includes an end effector. The handle includes a casing, a linear motor, a power transmission mechanism, and a quick change interface. The linear motor is disposed in the casing and configured to supply linear motion. The power transmission mechanism transmits the linear motion from the linear motor to the end effector. The quick change interface is connected to the end effector.

Handle for electric surgical stapler

A surgical stapler including a safety apparatus, including: a stapler part, a fixed handle, a safety apparatus, a transmission assembly, a propulsion assembly, and a trigger handle. The safety apparatus includes a safety piece and a fixing block. The propulsion assembly includes an ejector sleeve. The safety apparatus is fixed on the propulsion assembly and contacts with a surface of the transmission assembly. The safety piece is disposed inside the fixing block. At least one spring is disposed inside the fixing block to ensure elasticity of the safety piece.

Surgical stapler comprising safety apparatus

A surgical stapler, including: an anvil assembly, a reload assembly, a movable handle, a fixed handle, a transmission assembly, a propulsion assembly, a safety apparatus, and an anti-triggering device. The anti-triggering device includes two rows of holes and clamp strips. The transmission assembly is disposed inside the fixed handle. The clamp strips are arranged in longitudinal symmetry on one side of the anti-triggering device. A row of counterbores and a clamp plate having a structure matching with the clamp strip of the anti-triggering device are arranged at an inner side of the casing of the fixed handle. The safety apparatus is fixed at one side of the propulsion assembly. The anti-triggering device is clamped inside the casing of the fixed handle and is attached to a side surface of the safety apparatus.

Surgical stapler

A torque wrench apparatus comprises a top wrench, a bottom wrench, and a middle wrench. The top and bottom wrenches are configured such that either one of them rotates a first joint in a first direction, and the middle wrench is configured to rotate a second joint in a second direction opposite the first direction; or the top and bottom wrenches are configured such that either one of them immobilizes a first joint, and the middle wrench is configured to rotate a second joint in a first direction; or the middle wrench is configured to immobilize a first joint, and the top and bottom wrenches are configured such that either one of them rotates a second joint in a second direction opposite the first direction. A method for making and breaking joints with the apparatus is also introduced.
