A minimally invasive approach for surgery on portions of the heart and great vessels. A parasternal incision is made extending across a predetermined number of costal cartilages, e.g., a right parasternal incision extending from the lower edge of the second costal cartilage to the superior edge of the fifth costal cartilage. One or more costal cartilages, e.g., the third and fourth, are then excised to provide access to the portion of the heart or great vessels of interest, for example between a point approximately three centimeters above supra annular ridge and the mid ventricular cavity, and a desired procedure completed. A minimally invasive procedure for repair or replacement of the aortic valve is disclosed that includes making a transverse incision of about 10 cm in length over the second or third intercostal space in the thorax of the patient, dividing the sternum transversely following the incision, retracting the transversely divided sternum, exposing the ascending aorta, and incising the ascending aorta to provide access to an area adjacent the aortic valve.

A mask suitable for protecting the face of a patient during surgery comprises a transparent plastic shield which includes a transverse cutout that provides access to the nose and mouth, and a vertical gap which runs from the cutout to the shield's perimeter. Padding affixed to the perimeter of the shield's underside provides a cushion between the shield and face. The padding is preferably arranged such that the mask can be installed or removed without dislodging tubing inserted into the patient's nose or mouth via the transverse cutout. An attachment mechanism secures the shield to the face. A warming hood may be coupled to the protective mask. The hood preferably comprises outer and inner layers, with an access point at which air can be introduced between the layers; perforations on the inner layer permit warm air to be dispersed onto the patient.

The invention relates to a web-feeding printer including a plurality of printing mechanisms at least for printing over a printed material rail, and a fold mechanism (18) which splits samples from one or each printed material rails by means of transverse incision and forms at least one longitudinal flexure and / or at least one transverse flexure, and a turning and folding mechanism disposed between the printing mechanism and the fold mechanism, in this structure, at least one printed material rail (11) can be split into sub-rails (13, 14) by means of longitudinal incision, and / or one or each printed material rail or one or each sub-rail (13, 14) can be conveyed to at least one fold corrector via a turning rod and / or a guide roller (15). In accordance with the invention, at least one guide roller is arranged along conveying paths of one or more each printed material rail or one or each sub-rail by the turning and folding mechanism, both ends of the guide roller respectively include a regulation unit (21).

The invention relates to a pneumatic tyre tread of width W. This tread comprises a central region of a width of between 70% and 80% of the width W of the tread. The central region comprises one or more circumferential strips (17), each circumferential strip of the central region being delineated by two grooves of a width greater than or equal to 2 mm. Each circumferential strip of the central region comprises a contact surface intended to come into contact with the ground and a plurality of transverse incisions (19a, 19b, 19c) distributed uniformly in the circumferential direction. Each incision on the contact surface has a width of less than 2 mm so as to define an average circumferential cuts ratio. This average circumferential cuts ratio is between 0.5 times and 1.5 times the ratio between a mean thickness (E) of the circumferential strip and a mean circumferential radius of curvature (Rc) of said circumferential strip. The incisions divide the circumferential strip into a succession of blocks (21, 21b, 21c), each block having two edges (22a, 22b, 22c, 24) that intersect the contact surface of the circumferential strip. For each block of the circumferential strip, at least one of the edges of said block is extended radially by an inclined part (29a, 29b, 29c, 31) that forms a chamfer. This inclined part connects the edge to a side wall of the block in order to generate a circumferential offset between said edge and said side wall of the block.

Provided is a leg support for a rehabilitation training robot of lower extremity exoskeleton. The support is mostly composed of an inserting sleeve used for being movably connected with a movable sliding block, a support used for being movably connected with the inserting sleeve, and a binding strip used for penetrating through the support such that the leg support is connected with a person's thigh. The leg support for the rehabilitation training robot of lower extremity exoskeleton has following beneficial effects: the leg support is used for being installed on a thigh's mechanism of the robot; due to the fact that a movable groove is arranged in the thigh's mechanism and the movable groove is connected with the movable sliding block, the movable sliding block can drive the leg support to slide with passive movement of a mechanical leg so that discomfort caused by pulling and extrusion during the exercise training process of the leg support is avoided; due to the fact that a transverse cut is arranged in an inserting piece of the support, a second pin of the inserting sleeve is inserted through the transverse cut and can move up and down along a vertical inserting groove of the support; and the leg support is not easy to fall down and convenient to use.

The invention relates to a tyre tread (1) for a HGV divided into a central portion (20) and edge portions (30), the central portion (20) having a width Lc at least equal to 40% of the total width W ofthe tread and at most equal to 90% of said width W, the edge portions (30) being free of any transverse cut, the central portion (20) being provided with a tread design determined by at least one incision having a circumferential orientation (21) and a plurality of incisions having a transverse orientation (22, 22', 22'') distributed over the perimeter of the tread, said circumferential and transverse incisions having a depth at least equal to 60% of the thickness E of wearing material and being interconnected with one another in order to constitute a network, said circumferential and transverse incisions being extended by hidden channels (210, 220). Said tread (1) is such that the central portion (20) is axially defined by transverse incisions (22', 22''), each of said transverse incisions (22', 22'') ending in an end channel (221', 221'') open onto the tread surface (10) and extending into the thickness of the thread, and such that each end channel (221', 221'') is connected to thenetwork formed by the hidden channels (210, 220, 220', 220'').
