Utilize the release unit of this utility model embodiment, miniature actuator (such as monitor, therapeutic device) biological tissue be can be fixed to and the monitoring of various vital signs or the treatment of physiological decease carried out, described actuator is sent into safely enclosed space such as esophagus after, can realize the safe escape of actuator and external force mechanisms easily.
Continue below the work process of this utility model embodiment elastic deformation safety release device to be described in further detail in conjunction with Fig. 1, Fig. 4, Fig. 5 and Fig. 6.
Wherein, Fig. 4 is that this utility model embodiment elastic deformation safety release device enters the view before actuator is fixed behind the live body tract; Fig. 5 is that this utility model embodiment elastic deformation safety release device enters the view after actuator is fixed behind the live body tract; Fig. 6 is that this utility model embodiment elastic deformation safety release device enters the view after actuator behind the live body tract breaks away from described device.
The state that the actuator 15 that links to each other with this utility model embodiment elastic deformation safety release device by interior backguy 2 enters behind the live body tract can be with reference to Fig. 1.
In this utility model embodiment, for the ease of fixing of actuator 15, described actuator 15 has positioner, and described positioner comprises: rotating shaft 11, the clamping limb 9 that is arranged on the locking pin 12 around the rotating shaft 11 and can rotates around rotating shaft 11.
As shown in Figure 4, after actuator 15 entered the live body tract, tract soft tissue 17a entered in the clearance volume space 19, and locking pin 12 opens, and clamping limb 9 is in off-state with locking pin 12.
As shown in Figure 5, interior backguy 2 makes clamping limb 9 after rotating shaft 11 rotates by the effect of the pulling force of elastic deformation component 4 generations, falls into locking pin 12, thereby actuator 15 is clamped on the biological tissue wall.
As shown in Figure 6, continue tractive external cable 7, when the pull strength of 7 pairs of elastic deformation component of external cable, 4 generations surpasses the deformation strength degree of elastic deformation component 4, elastic arm 23 opens, interior backguy 2 is hauled out from line outlet 21, backguy 2 breaks away from elastic deformation component 4 promptly, thereby backguy 2 and this utility model embodiment elastic deformation safety release device separates in realizing.Then, by external cable 7 described device is pulled out from described live body tract.
Certainly, in this utility model embodiment, do not limit the concrete structure of described actuator 15 and positioner thereof, interior backguy 2 can reliably be connected with actuator 15 get final product.
As seen, utilize this utility model embodiment elastic deformation safety release device, can be safely, reliably enclosed space is sent in actuator, and realize the safe escape of actuator and external force mechanisms easily.
More than disclosed only be preferred implementation of the present utility model; but this utility model is not limited thereto; any those skilled in the art can think do not have a creationary variation; and, all should drop in the protection domain of the present utility model not breaking away from some improvements and modifications of being done under this utility model principle prerequisite.
