Various embodiments of tool assemblies are provided having at least one rotary input coupling and at least one linear input coupling for allowing either a rotary output or a linear output (e.g., from a tool driver on a surgical robot) to activate at least one mechanism of the tool assembly. For example, mechanisms of the tool assembly can include a clamping assembly, a firing assembly, an articulation assembly, and a roll assembly. The clamping assembly can open and close jaws of an end effector, the firing assembly can translate a knife assembly through the end effector to fire staples and cut tissue, the articulation assembly can articulate the end effector, and the roll assembly can rotate the elongate shaft and/or the end effector.

An endoscopic tissue resecting system that includes a reciprocating rotary surgical instrument for cutting tissue that includes a planetary gear assembly to vary rotational speed. A method of cutting and detaching tissue includes positioning an outer member such that tissue is located within a window in the outer member, engaging the tissue with an inner member, and simultaneously rotating at an increased speed relative to a rotary driver and translating the inner member to cut the tissue. A tangential cutting force is applied to the tissue with the inner member to mechanically cut and detach the tissue.

This invention is a method and tool for measuring and correcting deformities during osteotomy and treatment of fractures. The tool designed to restoring, alignment and correcting deformities of bone and joints is based on preoperative imaging and calculation of the deformity angle and planning for the deformity correction, the tool has a mechanism and power to force the bone to move according to the planning trajectory aiming at normal alignment during osteotomy and treatment of fracture and dislocation, it has a gauge to measure the degree of correction and the value of the bone displacement needed to overcome the bone overlapping and deformity angle in the fracture zone.

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

It is known to use pedicle screws and connectors to treat deformities in a spinal column. However, there are cases when screws must be installed in certain positions relative to each other as otherwise the connector may not fit correctly between them. A spinal anchoring element system is therefore provided, comprising a guide tool 60 for aligning a screw-path forming instrument 90 for use in forming a screw-path in a vertebra 10 for the subsequent installation of a pedicle screw 20, the guide tool comprising a guide tool stem 80 and a screw-path forming instrument receiving section 70, the guide tool stem and the screw-path forming instrument receiving section being immovable relative to one another.

Provided is an ultrasonic surgical knife blade. The projection of the blade on a shear plane is banana-like curved shape. From a proximal end to a distal end, the thickness of the blade varies from thick to thin, and then to thick and to thin again. The projection on a vertical shear plane is fruit knife-shaped. The height of the blade varies from high to low, and then gradually decreases, and an arc-shaped cutting groove is formed in the middle position. The present invention allows for an increase of swing amplitude in the bending direction and the effective working length of the blade. A boat-shaped or arc-shaped balance cutting groove is provided between the most distant node and a tip of the blade, such that the stability of ultrasonic vibration is improved.

A positioner, a conveyor, a tunnel-type wire passing system and an operating method thereof. The positioner includes first and second locating rods, a guide wire and a drive unit. The first locating rod defines a first channel extending therethrough along its axial direction. The second locating rod is connected to the first locating rod. The second locating rod defines a second channel extending therethrough along its axial direction. A distal end of the second channel extending in a direction intersecting a direction in which a distal end of the first channel extends. The guide wire is movably inserted in the second channel along the axial direction of the second locating rod. The guide wire is provided at a distal end thereof with a connecting unit. The drive unit is connected to the guide wire and drives the guide wire to move in the axial direction of the second locating rod.

A blood clot trimmer device and method for operating such is provided. The blood clot trimmer device is configured to pass through a work channel that is releasably attachable to an existing gastrointestinal examining device or through a working channel of an existing gastrointestinal examining device, and is configured to trim blood clots while the work channel that is releasably attachable to an existing gastrointestinal examining device is configured to remove trimmed blood clots from a site internal to a patient body via suction.

The invention provides systems, devices, and methods for the delivery, deployment, and positioning of magnetic compression devices at a desired site so as to improve the accuracy of anastomoses creation between tissues, organs, or the like.

In some embodiments, an apparatus includes a shaft, and a guide coupled and angularly deflectable relative to the shaft via a guide coupler to be transitioned between a delivery configuration and a deployed configuration in which a distal end of the guide points away from a centerline of the shaft. The apparatus further includes an elongate member removably and slidably disposable within a lumen of the guide and extendable distally relative to the distal end of the guide. The apparatus further includes a puncture member slidably disposable within a lumen of the elongate member and extendable distally relative to a distal end of the elongate member. The guide is configured to have the elongate member and the puncture member removed from the lumen of the guide and to receive in the lumen of the guide a therapeutic device, and to be angularly deflected while holding the therapeutic.
