Patent CA-3015433-A1 (CA)
Inventor: HU XIAOPING
IPC: H01F27/02
Filed: 2016-02-29
Abstract: Disclosed are an electromagnetic induction device and a method for manufacturing the same. The device comprises a magnetic cover (110) and at least one set of coils (120). The magnetic cover (110) consists of two or more magnetic units (111), and a closed magnetic flux loop can be formed within each magnetic unit (111). The magnetic units (111) are joined together to form a substantially closed integrated body having at least one cavity (112) therein, and dividing surfaces between the magnetic units (111) are disposed substantially along the magnetic flux loop without interrupting the magnetic flux loop. The coils (120) are placed in the cavity (112) formed by the magnetic cover (110), electrodes of the coils (120) are led out of the magnetic cover (110), and the magnetic flux loop in the magnetic cover (110) is formed after energization of the coils (120). The electromagnetic induction device of the present invention can substantially close coils, preventing magnetic flux leakage to a maximum extent. Further, since dividing surfaces between magnetic units are disposed along a magnetic flux loop, no air gap is generated in the magnetic flux loop, thereby effectively decreasing magnetic resistance.

Title: Laparoscopic clip applier
Inventor: PATEL ATAL C
IPC: A61B17/128
Filed: 2017-04-21
Abstract: A laparoscopic clip applier can have a geared clip feed mechanism and a direct jaw clamping mechanism to provide smooth operation over a clip application stroke of a movable handle. The geared clip feed mechanism can include an idler gear and two drive gear racks to advance a feed slider feeding a clip to a jaw assembly. The two drive gear racks can be positioned to provide different gearing during clip feed and firing portions of the clip application stroke, allowing efficient packaging of the clip feed mechanism. A spring can rapidly withdraw the feed slider once the clip has been fed and before clamping begins. The movable handle can have a direct connection to a clamping slider to enhance user feedback during clamping of the clip. After clamping the clip, the movable handle can also assist in returning the clamping slider to an initial position for firing another clip.
