A cardiac pacing system and a pacemaker fixation device are disclosed. The pacemaker fixation device includes a ring-shaped stent and at least one contractible member. The ring-shaped stent is configured to load a leadless pacemaker and easily fix it at a target site in a patient's body reliably without dislodgement. A connecting element in the contractible member can be reliably connected to an external mechanism, thus facilitating retrieval and removal of the cardiac pacing system with an increased success rate. During implantation, the contractible member can be adapted by operating the external mechanism to adjust the pacing location for the leadless pacemaker, thus allowing the operator to easily determine the best pacing location that can result in enhanced pacing performance of the leadless pacemaker. Further, the leadless pacemaker may be fixed in the atrium in order to pace the atrium, thus reducing non-physiological pacing with atrioventricular desynchronization.

This invention discloses a method for etching a see-through thin film solar module, comprising: printing ink paste which resists the etching of etching solutions in the protected area of the thin film solar module which is placed under a screen; drying and solidifying the ink paste; coating etching solutions on the thin film solar module; and removing the ink paste. The method of this invention can accurately position the see-through area, achieve various selections of see-through patterns, facilitate the realization of the see-through function in large-area thin film solar modules, and alleviate the problem that a short circuit easily occurs in a see-through thin film solar module.
