Retraction Mechanism For Medical Device

A device comprises a retractable shaft; a shaft biasing spring; and an actuator button. The retractable shaft is biased away from the actuator button by the shaft biasing spring. A magnetic attracting force is created between the retractable shaft and the actuator button upon actuation of the actuator button. Before actuation, a distance between the actuator button and the retractable shaft is great enough that the magnetic attracting force is less than a biasing force of the shaft biasing spring such that the retractable shaft is biased away from the actuator button. Upon actuation, the actuator button is depressed to make the distance between the actuator button and the retractable shaft sufficiently small such that the magnetic attracting force is greater than the biasing force of the shaft biasing spring to allow the retractable shaft to be biased towards the actuator button.

Device for the repeated piercing of an organic tissue, an application module and a method thereof
09808286 · 2017-11-07 · ·

A device for repeated piercing of an organic tissue and method thereof are disclosed. The device may comprise an arrangement of application tools each of which is connected to an operating mechanism and has a distal tool end which is formed for at least one application tool with a penetration device, whereby by way of the operating mechanism the tools can be displaced relative to each other between an initial position and a penetration position. During the relative movement, the effect direction of an application force provided by at least one application tool is counter to the effect direction of the application force provided by the other application tool. A mechanical actuation device, which is connected to the operating mechanism, is suitable for repeatedly effecting the relative displacement of the at least one application tool between the initial position and the penetration with an operating frequency.

MULTI-SENSOR PROCESSING FOR SURGICAL DEVICE ENHANCEMENT

A computing device may include an input, a processor, and an output. The device may be configured to receive two points of surgical sensor data from different sensors. The sensors may include wearable patient sensors and/or surgical theater environmental sensor system. The processor may determine a surgical device setting (e.g., a closure load for a powered surgical stapler, or for example, a power level of a surgical energy device). And the output may send a signal indicative of the determined setting. A surgical device may receive the signal and perform a surgical action based on the determined setting. Using a combination of patient-specific and/or surgical-environment-specific sensor inputs to determine a more optimal device setting may lead to better device perform and ultimately better patient outcomes.
