Devices, Systems, and Methods for detecting a 3-dimensional position of an object, and surgical automation involving the same. The surgical robot system may include a robot having a robot base, a robot arm coupled to the robot base, and an end-effector coupled to the robot arm. The end-effector, surgical instruments, the patient, and/or other objects to be tracked include active and/or passive tracking markers. Cameras, such as stereophotogrammetric infrared cameras, are able to detect the tracking markers, and the robot determines a 3-dimensional position of the object from the tracking markers.

The present disclosure is directed to an inflatable-cushion inflation and sealing device. The device includes an inflation assembly configured for insertion between first and second overlapping film plies. The inflation assembly includes a fluid conduit configured to direct a fluid in between the plies to form one or more cushions. The fluid conduit includes a nozzle. The inflation assembly includes a cutting member. The cutting member includes a blade holder with a blade and a blade guard mounted thereon. The blade guard has a safety position in which the blade is covered and a retracted position in which the blade is exposed. Installation of the blade holder onto the inflation assembly automatically positions the blade in the working position with the blade guard retracted. Removing the tray from the inflation assembly automatically positions the blade in the safety position by covering the blade with the blade guard.

A scalpel body including an attachment for a removable blade, a spray head adapted to operatively deliver a surgical liquid as a spray proximal to a removable blade, and an external connection for allowing the spray head to be connected to an external supply of surgical liquid. A release mechanism allows for selective release of the spray, proximal to the blade.

Surgical knives are disclosed, for initiating percutaneous access to a surgical site. The knife has a body with a rear handle and a front cutter portion. It may have a central cannulation to receive a guide wire, along a front-to-rear operating axis. The cutter portion has first and second blades opposed across the axis, each having an outward cutting edge directed laterally outwardly relative to the operating axis and a flat outward face also directed laterally outwardly relative to the operating axis and transversely to the respective outward cutting edge. The first and second outward faces of the two blades converge forwardly to their tip points, which lie close to the axis, and their cutting edges are oppositely directed. Alternatively a single blade may be used, forwardly convergent with the axis.

A blade holder for assembling a replaceable blade comprises a supporting base assembling with a shank, a mounting rod integrally extending from the supporting base, and a blade limiting assembly. The mounting rod is formed with a first mounting hole. The blade limiting assembly comprises a limiting member provided on the mounting rod and is controlled to move a displacement stroke relative to the mounting rod, a limiting block provided in the first mounting hole, and an elastic member provided in the first mounting hole and connected to the limiting block. The limiting member comprises a limited position and an unblocked position in the displacement stroke. The limiting block is located on a path of the displacement stroke, and the limiting block comprises a stop position that the limiting block protrudes a surface of the mounting rod, and a release position that sinks into the first mounting hole.

An ultrasonic scalpel handle, comprising a handle housing (11) and a transducer assembly (12). The transducer assembly (12) is integrally accommodated in the handle housing (11) and can rotate about its own axis. The transducer assembly (12) comprises a transducer shell (121) and a transducer (122) fixedly disposed to each other, and a conductive member (123) fixedly provided outside the transducer shell (121). The conductive member (123) has at least a conductive portion. The transducer (122) is fixedly and electrically connected to the conductive portion. An electric element (13) is further fixedly provided in the handle housing (11). In the process that the transducer assembly (12) rotates about its own axis with respect to the handle housing (11), the electric element (13) is always in contact with the conductive portion to maintain electric connection. In this way, in the process that the transducer assembly rotates about its own axis in the handle housing, power cord does not rotate with it, and the power cord may further extend in the lower part of the handle, such that a series of problems of heavy burden on the arm and easy fatigue, and knotting of the power cord, etc. caused by the power cord extending from the rear portion of the handle housing are avoided.
