A long articulating steerable clip applier affixed to a user-operated handle. A surgical jaw assembly is attached to the other end of the clip applier. The clip applier is composed of articulating phalanges that are connected end to end by pivoting links and capable of angulations relative to one another when subjected to a tensile force. Each phalange has opposing s-shaped exterior grooves that form two continuous spiral-shaped channels for holding tension wires once the phalanges are assembled. Multiple tension wires are attached to opposite ends of adjacent phalanges. When each wire is pulled, this tensile force causes the phalanges to pivot at equivalent angles with each other. As each individual phalange pivots by an equivalent angle, the sum of these angles causes the free end of the clip applier to pivot by a large angle or a cascading actuation effect.

Methods and apparatus for repair of toe deformities using a bioabsorbable pin. The apparatus is a kit of part comprising a bioabsorbable pin, a predrill, a bone tamp, a cutter and a forceps. One surgical method of repairing toe deformities includes resecting a proximal interphalangeal joint, drilling a hole in a proximal phalanx using a proximal portion of a pin, removing the pin from the proximal phalanx, drilling a tip of a toe through middle and distal phalanxes, driving the pin retrograde and traversing the distal, middle and proximal phalanxes until the pin stops advancing due to resistance at a proximal cortex, holding the pin and powering a pin driver to separate a distal portion of the pin, and suturing the wound.

The invention belongs to the technical field of robots, and relates to a finger structure and a robot. In the finger structure, a proximal phalanx shell, a middle phalanx shell, a distal phalanx shelland a connecting rod form a four-rod mechanism, the proximal phalanx shell serves as a fixing frame, a driving assembly drives the middle phalanx shell to swing, the distal phalanx shell is in linkage with the connecting rod, the distal phalanx shell swings in the swinging direction of the middle phalanx shell, and the finger structure is integrally bent and straightened. The connecting rod is arranged to be a first bent section, and a notch of the first bent section faces the back face of the middle phalanx shell. When the finger structure is straightened, namely the distal phalanx shell isflush with the middle phalanx shell, the inner wall of the first near end at a distal phalanx opening extends into the bottom of the notch of the first bent section, so that the inner wall of the first near end can be closer to the center of the distal phalanx opening. The far finger opening of the finger structure can be manufactured to be small, and the integrity of the appearance of the distalphalanx shell is improved. Due to the existence of the first bent section of the connecting rod, when the distal phalanx shell is impacted, the connecting rod shows certain elasticity and absorbs theimpact.
