A dermal conditioning device is for creating at least one pressure point on at least an external surface of an eyelid. The device includes at least one skin tissue lesion generator, at least one controller, a power supply and a housing, the controller coupled to the skin tissue lesion generator. A power supply couples to the skin tissue lesion generator and the controller and the housing encasing the skin tissue lesion generator and the controller. The controller controls the skin tissue lesion generator to generate at least one signal and to apply the signal to stress the external surface of an outer layer of the eyelid, the stress causing a formation of the pressure point on the eyelid without tissue coagulation, thereby activating at least one of a corneal reflex, a menace reflex, and a lacrimation reflex of the eyelid by activating at least one nociceptor on the eyelid.

The invention provides a device, a kit for repairing and fixing articular cartilage, and a method for the same. The device comprises a costal cartilage rod, an outer sleeve, a drilling part, and an auxiliary implantation component; the drilling part comprises a drill sleeve and a drill bit matching an inner diameter of the drill sleeve; the auxiliary implantation component comprises a cartilage rod sleeve and an auxiliary pushing element, the costal cartilage rod has a rod-shaped structure with a diameter ranging from 3 mm to 8 mm and less than an inner diameter of the cartilage rod sleeve, and the costal cartilage rod is obtained from processing of costal cartilage. The costal cartilage is selected from the group consisting of autologous costal cartilage, allogeneic costal cartilage, or xenogeneic costal cartilage. Costal cartilage is processed into a costal cartilage rod by using the device provided in the present invention.

A surgical tool and method for engaging and manipulating a bone includes a tool body having a main body axis, a threaded end, and a handling end, the threaded end having threads and a tool stop. The handling end is positioned to allow a user to grasp, manipulate, and rotate the tool body around the main body axis. The threads are positioned to allow the surgical tool to bore into and engage the bone when the tool body is rotated in a boring direction around the main body axis, the threads allowing for tightening engagement with the bone as the tool body is rotated in the boring direction around the main body axis. The tool stop is positioned to prevent the tool from being further rotated around the main body axis to prevent further boring into the bone when the tool stop contacts the bone.

Disclosed herein are patient-specific cutting guides for guiding a surgical instrument for resecting a portion of a glenoid of a patient. The cutting guides include a base portion having a contact surface shaped to substantially match at least a portion of a cavity of the glenoid. The base portion has a guide hole extending therethrough in which the guide hole has an axis coaxial with an axis of rotation. The cutting guides include one or more stabilization members extending outwardly from the base portion and having a contact surface shaped to substantially match an outer surface of a portion of a scapula of the patient. The stabilization members are oriented to take into account the patient's anatomy in orienting and stabilizing the guide with respect to the glenoid. The guide hole of the base portion is for guiding the surgical instrument to create a guide hole in the glenoid.

A handle of a device such as an endoscopic surgical appliance is provided with a grip for actuation of an effector mechanism positioned at a distal end. A grip force attenuator within the handle absorbs excessive force after the grip force required to fully actuate the effector mechanism has been reached. The handle includes a first spring which deflects in response to hand grip force up to a predetermined level for actuation of the effector mechanism and a second spring which deflects in response to hand grip force which exceeds the predetermined level without applying such excess force to the first spring.

A surgical sizer sound, comprising an actuatable shaft. The surgical sizer sound also comprises an angled shaft coupled to the actuatable shaft. The surgical sizer sound also comprises a sizer coupler comprising a guide tip and a limit, pivotably coupled to the angled shaft and a sizer, removably coupled to the sizer coupler.

A surgical stapler includes a first half having a first elongate member and a surface with staple forming pockets. The stapler also includes a second half for releasably coupling with the first half and including a second elongate member having a distal portion for deploying staples. The elongate members are pivotable relative to each other about a pivot axis when the halves are releasably coupled. The stapler further includes a latching member for selectively clamping the halves in a clamped state. The stapler also includes a detent member extending laterally from one of the halves toward the other. The stapler further includes a shoulder member positioned on the other of the halves and configured to selectively engage the detent member in response to rotation of the first elongate member away from the second elongate member to an open state in which the elongate members assume a maximum angular orientation.

Embodiments generally relate to preventing overpenetration of a drill bit during surgery. A system comprises a drill guide comprising a housing; a tubular member extending from the housing; a depth-stop movably disposable within the housing; and a ratchet adjacent to the depth-stop, the ratchet configured to retract or extend the depth-stop relative to the housing.

A system is provided for increasing skin rejuvenation of a region of a patient's skin comprising a pulsed electromagnetic field (PEMF) frequency generator for constantly providing electromagnetic pulses to said region of a patient's skin and a deep tissue diathermy device for constantly applying heat to said region of a patient's skin up to temperature T. The system is adapted for simultaneously applying heat and PEMF to the region of a patient's skin. Application of the system increases skin rejuvenation such that the skin rejuvenation increase (SRI) is greater than the sum of the SRI provided by electromagnetic pulses increase and the SRI provided by the deep tissue diathermy device increase.

Implants include fixation features which slidingly receive fixation elements. The fixation features may be negative or positive features, such as undercut channels or posts. Examples include unicompartmental tibial trays having a ridge protruding from the bone-facing side, an undercut channel formed within the ridge. Instruments are disclosed for preparing a ridge-receiving feature in bone.
