Abstract: Embodiments of this application provide a fire-fighting switch device and a fire-fighting system, which are applied to the field of fire-fighting. The fire-fighting switch device includes a plurality of fire detection switch units, where the fire detection switch unit includes one or more fire detection switches, the one or more fire detection switches form at least one switch path, the fire detection switch is configured to turn on when a fire is detected, and any one of the switch paths is configured to transmit a voltage signal to a fire-extinguishing device when all of the fire detection switches on the switch path are turned on. In this solution, when a fire is detected by one fire detection switch unit, the fire-extinguishing device can be controlled to extinguish the fire provided that all fire detection switches on one switch path in the fire detection switch unit are turned on.

Abstract: A bone trabecular fusion cage for implanting into an intervertebral disc is disclosed. The fusion cage includes a bone trabecular housing made of titanium alloy powder material with trabecular housing accommodation space therein. A side wall of the bone trabecular housing is provided with a plurality of pores, and sclerotin can grow into the bone trabecular housing through the pores to securely fix the bone trabecular fusion cage in the intervertebral disc; and a liner made of polyether-ether-ketone material and fixed in the accommodating space of the bone trabecular housing, wherein the polyether-ether-ketone liner gpores can provide good elastic modulus of bone. With the product of the present disclosure, bone implantation is not required, the patient recovers fast, and excellent fusion effect can be obtained.

Abstract: The present invention discloses a renovated titanium mesh used for repairing bone defects in knee joint replacement. The renovated titanium mesh (1) includes transverse ribs (2) for implanting the renovated titanium mesh into a human body and longitudinal ribs (3) for supporting the transverse ribs (2). The transverse ribs (2) and the longitudinal ribs (3) are crisscrossed to form the meshed renovated titanium mesh (1). In the renovated titanium mesh of the present invention, the meshed structure of the renovated titanium mesh can ensure the bone ingrowth of a patient, and the renovated titanium mesh can be cut to provide a high degree of matching for the patient and to thus satisfy the patient's demand; the renovated titanium mesh can better ensure the bone ingrowth of the patient and be advantageous for the later recovery of the patient.
