Patent CA-2851747-C (CA)
Inventor: JI YING
IPC: A61B34/20

Granted: 2016-07-26
Abstract: Disclosed are a determination method for the directional calibration parameters of a surgical instrument and a calibration tool thereof and a determination method for the action direction of the surgical instrument. The determination method for the directional calibration parameters comprises: installing an analyte (40) of a tracking marker (21) on a calibration tool (30), making the analyte maintain a constant direction and revolve on its axis, determining at least two three-dimensional rotation matrices of the tracking marker by a position tracking device, and using the three-dimensional rotation matrixes to determine the direction calibration parameters by means of the two-point correlation formula or the rectilinear rotation equation in a three-dimensional space. The current action direction of the surgical instrument is determined based on the determined directional calibration parameters and the current three-dimensional rotation matrices of the tracking marker. The method can determine the directional calibration parameters of the surgical instrument without placing the analyte in a known direction or determining two points of the direction, and thus can determine the action direction of the surgical instrument in actual use, providing reliable directional information for doctors, and ensuring a smooth operation and improving surgical precision.

Abstract: A sliding sleeve (100) opens with a deployed ball (B). The sleeve has a seat (150) disposed in the housing (120), and the seat has segments (152) biased outward from one another with a C-ring or other biasing element (154). Initially, the seat has an expanded state in the sliding sleeve so that the seats segments expand outward against the housing's bore. When an appropriately sized ball is deployed downhole, the ball engages the expanded seat. Fluid pressure applied against the seated ball moves the seat into the inner sleeve's bore. As this occurs, the seat contracts, which increases the engagement area of the seat with the ball. Eventually, the seat reaches the shoulder (137) in the inner sleeve so that pressure applied against the seated ball now moves the inner sleeve in the housing to open the sliding sleeve's flow port (126).
