Devices, systems and methods are disclosed for repairing soft tissue. The surgical system allows for the creation of tissue repair by grasping, aligning and sewing or fixing tissue. For example, this system may be used for clipping together excessive capsular tissue and reducing the overall capsular volume. The deployment device includes a central grasping mechanism and an outer clip delivery system. The clip embodiments may be single or multi-component (penetration and locking base components) that penetrate tissue layers and deploy or lock to clip the tissue together. An example of the system is used to reduce the joint capsule tissue laxity and reduces the potential for subluxation or dislocation of the joint by either restricting inferior laxity (anterior or posterior) and resolving or eliminating pathologic anterior or posterior translation.

A glenoid component for treatment of rotator cuff arthropathy includes attachment to the coracoid process by a pin or post imbedded into a hole formed in the coracoid process. The glenoid component preferably also has a keel for extending into the glenoid fossa and protrusions such as ridges cemented to the acromion process. This way, an attachment point is preferably provided in/on the coracoid process, the acromion process, and the glenoid fossa, and at least two of the attachment points include a protrusion extending into a hole/slot drilled or otherwise formed in the bone. A jig is used for guiding/drilling into the bone, wherein the jig has both a glenoid fossa drill guide and a coracoid drill guide. The coracoid drill guide includes structure that abuts against opposing sides of the base of the coracoid process to prevent rotation of the jig relative to the scapula.

In one embodiment, a method for treating an infected implant area of a knee joint comprises surgically accessing the implant area, and inserting a tibial component into the tibia using an antibiotic-impregnated material.

The invention discloses a sand stabilization and water locking net suitable for desertified soil, and belongs to the technical field of soil sand stabilization and water locking. A plurality of lowerembedded water locking bodies and upper anti-raising sand stabilization bodies which are distributed in a staggered manner are arranged at the upper end and the lower end of a sand prevention net, theupper anti-raising sand stabilization bodies achieve an effect of preventing raising and stabilizing sand on the surface layer of the upper end of sandy soil, the lower embedded water locking bodieslocated in the surface layer of the sandy soil are used for naturally locking water under the environment of natural rainfall or manual irrigation, the stored water is guided into the soil through a plurality of capillary drainage pipes, arc-shaped sand grabbing pieces and matching structures of flow guide soil breaking cones and conical seepage-proofing bodies, the balanced and slow wetting on the soil is effectively achieved, through cooperation of embedded rods and the conical seepage-proofing bodies, the seepage-proofing effect is effectively achieved while good sand stabilization is achieved, meanwhile, soil fixing agent permeation bags are arranged in the lower embedded water locking bodies, when water is stored in the lower embedded water locking bodies, soil fixing agents can be released and dispersed into the soil, and the sand stabilization and water locking effects of the soil are further improved.

The engineering problem of the claimed invention is to enhance wear-resistance of drill pipe tool joints. The proposed drill pipe consists of a body with upset ends and tool joints connected by means of friction welding, having tapered thread and a double coating, the first layer being applied by means of thermo-diffusion zincing and the second one, by means phosphate treatment. Enhancement of tool joint life, as compared to the tool joints with phosphate coating only, allows no overdimension to be stipulated for future repair purposes, which saves up to several kilos of metal per tool joint, decreasing the drill string weight by several tons. With a view to increasing the joints' durability and reliability of welding seams the thickness δ of the first coating layer as function of thread conicity K is adjusted according to the following formula: δ=0.09 . . . 0.13 K. The segment at 15 to 25 mm from the welding spot on joints is coated with phosphate only.
