An orthopedic implantation operation system includes a power drill mechanism and a linear advancing mechanism. The linear advancing mechanism includes a linear motor; the linear motor is connected with the power drill mechanism to drive the power drill mechanism to make a linear reciprocating motion to realize the advancement motion of the surgical tool. The present invention provides the driving force of the linear reciprocating motion of the power drill mechanism through a linear advancing mechanism, and combines with a power drill mechanism to clamp surgical tools such as a guide pin, reamer, tap and a vertebral pedicle screw, etc. so as to realize the operation of orthopedic implantation. Compared with artificial orthopedic implantation operations, the operation is stable, the impact on the human body is small, and the operation efficiency and accuracy of orthopedic implantation operations are higher, avoiding accidental injuries that may be caused by manual orthopedic implantation.

The slip ring assembly includes a slip ring, a first conductor mounted on the slip ring, a commutator rotatable relative to the slip ring, and a second conductor mounted on the commutator. The slip ring assembly further includes a flexible member disposed between the slip ring and the commutator. The flexible member comprises a body and flexible protrusions extending from the body, wherein the flexible protrusions are elastically deformed against the first slip ring.

A surgical apparatus having an electrical conductor with a strain relief is provided. A tool assembly is supported on a body portion and is articulable relative to the body portion. The tool assembly includes an identification assembly in electrical communication with a powered handle assembly. An electrical conductor extends from a connection assembly in the body portion to the identification assembly. The electrical conductor includes a strain relief portion for accommodating the articulation of the tool assembly relative to the body portion.

Medical systems and methods for making and using medical systems are disclosed. Example medical systems may include an atherectomy system configured to engage and remove plaque from walls in vessels of a vascular system. The atherectomy system may include a drive shaft, a rotational member coupled to an end of the drive shaft, a motor coupled to the drive shaft to rotate the rotational tip, and a control unit configured to control a motor state of the motor. The motor may be an electric motor. The control unit may adjust the motor state to decelerate the motor in response to detecting a jam or a stall condition. The jam or stall condition may be detected when a speed of the motor or other motor state reaches or goes beyond a threshold value as prescribed by a reference schedule.

An end effector for a surgical clip applier includes a body having a proximal end and a distal end, a head arranged at the distal end, and first and second jaw members mounted to the head. A linear actuator is arranged within the head and is operable to collapse and open the first and second jaw members.

A surgical instrument comprising an end effector is disclosed. The end effector comprises a surgical dissector. The surgical dissector can apply mechanical and/or electrosurgical energy to treated tissue.

A surgical system includes a control circuit, a surgical instrument, and a user interface is disclosed. The surgical instrument includes a plurality of components and a sensor. Each of the plurality of components of the surgical instrument includes a device parameter and is configured to transmit its respective device parameter to the control circuit. The sensor of the surgical instrument is configured to detect a tissue parameter associated with a proposed function of the surgical instrument, and transmit the detected tissue parameter to the control circuit. The control circuit is configured to analyze the detected tissue parameter in cooperation with each respective device parameter based on a system-defined constraint. The user interface is configured to indicate whether the surgical instrument comprising the plurality of components is appropriate to perform the proposed function.

A surgical stapling instrument is disclosed. An end effector for the surgical stapling instrument comprises a staple cartridge assembly and an anvil. The staple cartridge assembly comprises a proximal end, a distal end, and a cartridge body comprising a shortened nose at the distal end. The staple cartridge assembly further comprises staples removably stored in the cartridge body, a driver configured to support at least one of the staples, and a sled movable toward the distal end. The sled comprises a ramp configured to lift the driver and at least one of the staples and a base, wherein the shortened nose of the cartridge body is shorter than the base of the sled. The anvil comprises a staple forming surface comprising a plurality of staple forming pockets and a blunt distal nose extending downward toward the staple cartridge assembly.

A surgical instrument connectable to a surgical energy module that is configured to provide a first drive signal at a first frequency range for driving a first energy modality and a second drive signal at a second frequency range for driving a second energy modality is provided. The surgical instrument can comprise a surgical instrument component configured to receive power from a direct current (DC) power source, an end effector, and a circuit. The circuit can be configured to convert the first electrical signal to a DC voltage, apply the DC voltage to the surgical instrument component, and deliver the second energy modality to the end effector according to the second drive signal. Alternatively, the circuit can be disposed within a cable assembly configured to connect the surgical instrument to the surgical energy module.

A modular energy system including a header module configured to removably connect to an energy module. The energy module can comprise a port configured to deliver one or more energy modalities to a surgical instrument connected thereto. The header module can comprise a display screen configured to display a user interface. The header module can further include a control circuit configured to detect attachment of energy modules to the modular energy system and control the display of the user interface to display UI portions for each connected module and reconfigure the displayed UI portions to accommodate the new UI portions as additional energy modules are connected to the modular energy system.
