Abstract: A prosthesis system for minimally invasive femoral head replacement surgery includes a prosthesis having a first and second ends, a femoral head prosthesis being provided at the first end of the prosthesis, the prosthesis being provided with a nail hole, and the femoral head prosthesis partially protruding from the first end of the channel; an extension rod detachably and fixedly connected with the second end of the prosthesis; a guiding frame having a positioning sleeve and a guiding sleeve, the positioning sleeve being sleeved outside the extension rod and positioning the extension rod, after the extension rod is positioned, a center line of the guiding sleeve and a center line of the nail hole are on the same straight line; and a locking nail fixed to the nail hole of the prosthesis, both ends of the locking nail protruding out of the prosthesis.

Abstract: A flow battery field, an electrode slurry, a slurry electrode, a flow battery, and a stack are disclosed. The electrode slurry comprising electrode particles and electrolyte that contains active substance. Based on 100 pbw active substance, the electrode particles are 10-1,000 pbw. The slurry electrode comprises: a bipolar plate, a current collector, and a slurry electrode reservoir configured to store electrode slurry. In the two opposite sides of the bipolar plate, one side is adjacent to the current collector, and the other side is arranged with a slurry electrode cavity, and flow channels are arranged and extended between the bipolar plate and the slurry electrode cavity, so that the electrode slurry is circulated between the slurry electrode cavity and the slurry electrode reservoir. A flow battery that employs the electrode slurry can provide higher and more stable power output under the same current condition and is lower in cost.

Abstract: A stable female terminal comprises a substrate. Two side edges of the front end of the substrate are turned to form two opposite elastic pieces. A slot allowing a male terminal to be inserted therein is formed between the two elastic pieces. The two elastic pieces draw close to each other to form an elastic jaw used for clamping two sides of the male terminal inserted into the slot. A female terminal external connection part is formed at the rear end of the substrate. Contacts have a large positive force when the male terminal and the female terminal are connected, so that the male terminal and the female terminal can be in contact more stably and reliably, and larger currents can pass through the male terminal and the female terminal.

Abstract: The invention discloses an electrical connection terminal comprising a substrate, wherein an edge of the front end of the substrate is extended and folded to form an elastic piece, a convex contact is formed on the elastic piece, and an external connection part is formed at the rear end of the substrate. The invention further discloses a male-female matching type electrical connector using the electrical connection terminal, wherein at least one of two terminals to be connected is the electrical connection terminal. The structure is simple, elasticity is high, contacts are in close contact, electrical connection is more reliable, and production and assembly of products using the electrical connection terminal are facilitated.

Abstract: An insulated electrical connector formed by one-time injection molding is disclosed. A base of each metal female terminal has two edges extending upward and inclining relative to each other to form elastic clamping pieces, and an edge extending outwards to form a weld leg. An insulated rubber core is formed on the metal female terminals by one-time injection molding. The bases are embedded in the insulated rubber core. The elastic clamping pieces are received in cavities of the insulated rubber core. Insertion holes corresponding to the elastic clamping pieces are formed in bottoms of the cavities. Conical guide-in faces are formed at bottoms of the insertion holes. The weld legs stretch out of the insulated rubber core. The insulated electrical connector is convenient to install and realizes stable electric connection.
