Biopsy system

A biopsy system is provided including a housing and a biopsy instrument operatively associated with the housing and configured and dimensioned to remove a tissue sample from a patient. A firing module is included that is detachably engageable with the housing and operatively associated with the biopsy instrument to facilitate selective rapid advancement of at least a portion of the biopsy instrument toward a targeted location with the patient. The biopsy instrument includes a tissue receiving portion. The system may include an indexing assembly disposed within the housing and configured to cooperate with the biopsy instrument to selectively orient the tissue receiving portion. The indexing assembly may include a manual gearing assembly configured for selective orientation of the tissue receiving portion. The system may include a linear advancement control assembly disposed within the housing and configured to effect linear actuation of a tubular knife member. An optical sensor may be disposed adjacent a portion of the tubular knife member and oriented to detect the orientation of a lateral opening formed through the tubular knife member. A carriage may be slidably disposed within the housing and configured to releasably retain at least a portion of the biopsy instrument. A method of performing a surgical biopsy is disclosed.

Robot cable gallery field fire early warning and fire extinguishment method, device and system

The invention discloses a robot cable gallery field fire early warning and fire extinguishment method, device and system. The method comprises the steps that whether to receive a warning signal or notis judged; if not receiving the warning signal, a fire protection inspection robot conducts automatic inspection, receives tunnel internal environment information and crucial location temperature information, compares the tunnel internal environment information and the crucial location temperature information with set fire threshold values and generates a fire signal or conducts field fire risk assessment; if receiving the warning signal or generating the fire signal during automatic inspection, the robot conducts fire pre-identification according to the risk analysis and assessment result, optimizes fire pre-identification at the early smoldering stage, rapidly positions the location of a pre-identified fire source, determines the authenticity, performs the fire extinguishment task and then safely evacuates after completing the task. Through the robot cable gallery field fire early warning and fire extinguishment method, device and system, the capabilities of conducting fire safety pre-warning and fire warning, rapidly searching for the fire source and extinguishing the fire for a cable gallery (tunnel) are greatly improved.

Brake structure for a roll-up door

A brake structure for a roll-up door includes a brake drum fixed to a transmission shaft of a speed reducer. The brake drum receives a pair of brake shoes in opposite inner sides thereof. The brake shoes are pivotably connected to each other at an end of each brake shoe. A linking resilient member is connected between the free ends of the brake shoes. A brake pad is attached to a surface of each brake shoe facing the inner surface of the brake drum. A controlling lever is disposed at the top of the speed reducer corresponding to the free ends of the brake shoes. One end of the controlling lever is connected to an end of a fixing resilient member. The other end of the fixing resilient member is connected to a moving iron of a first solenoid. A clasping block is connected to the moving iron of the first solenoid. The other end of the controlling lever is connected to a moving iron of a second solenoid. A controlling block is disposed at the controlling lever between the free ends of the brake shoes and in contact to the free ends of the brake shoes. A brake control solenoid is disposed at the top of the speed reducer. The brake control solenoid is connected to a power supply with capacitance character. A moving iron of the brake control solenoid is connected to a connecting rod mechanism. The clasping block is connected to the connecting rod mechanism.
