Devices for assisting with heart valve manufacturing
An assistance system that can be used for prosthetic heart valve manufacturing or suturing procedures includes an automated fixture that can comprise an articulation arm and a target device holder. The target device holder can be positioned and oriented to reduce operator strain during a manufacturing or inspection process. The assistance system includes a user input device enabling the operator to move between positions to assist in such processes. The assistance system can also be trained by capturing sequences of position data corresponding to a manufacturing or inspection process.
1. A suturing assistance system comprising:
an automated suture fixture comprising a plurality of motorized actuator devices and a suture target holder, the automated suture fixture being configured to position a target suture device mounted to the holder, the target suture device comprising an outside surface and an inside surface defining an at least partially open inside cylinder cavity;
a user input device configured to receive user input; and
a controller configured to receive user input from the user input device and to provide position control signals to the automated suture fixture to position the target suture device, the controller further configured to:
in response to a first input received from the user input device, cause the automated suture fixture to position the target suture device in a first position to enable an operator to use a first hand to execute an outside-to-inside stitch by puncturing a needle through the outside surface to the inside cylinder cavity; and
in response to a second input received from the user input device, cause the automated suture fixture to position the target suture device in a second position to enable the operator to use the first hand to execute an inside-to-outside stitch by puncturing the inside surface.
2. The suturing assistance system of claim 1 , wherein the target suture device positioned in the second position enables the operator to perform a pre-punch on the prosthetic human implant device using a handheld tool operated by a second hand of the operator.
3. The suturing assistance system of claim 1 , wherein the target suture device is a prosthetic human heart valve implant device.
4. The suturing assistance system of claim 1 further comprising a data store storing suturing procedure script data that includes data representing a plurality of positions of the automated suture fixture assembly.
5. The suturing assistance system of claim 4 , wherein the controller is configured to retrieve the first position and the second position from the suturing procedure script data.
6. The suturing assistance system of claim 1 further comprising a camera system configured to generate an image of the target suture device.
7. The suturing assistance system of claim 6 , wherein the first position corresponds to a focal length from a camera lens of the camera system.
8. The suturing assistance system of claim 6 , wherein the controller is further configured to, in response to a third input received from the user input device, cause the automated suture fixture to circumferentially rotate the target suture device in place while maintaining at least some portion of the outside surface of the target suture device in focus of the camera system.
9. The suturing assistance system of claim 1 , wherein operation of the automated suture fixture provides for reduced physical strain of the operator.
10. The suturing assistance system of claim 1 , wherein the first position presents the outside surface to the operator and the second position presents the inside surface to the operator.
11. A suturing assistance system comprising:
an automated suture fixture comprising a plurality of motorized actuator devices and a suture target holder, the automated suture fixture being configured to position a target suture device mounted to the holder;
a data store configured to store data indicating a position of the automated suture fixture;
a user input device configured to receive user input; and
a controller communicatively coupled to the user input device, the data store, and to the automated suture fixture, the controller configured to:
in response to a first input received from the user input device, store first data in the data store indicating a position of the automated suture fixture, the automated suture fixture having been at least partially manually manipulated so that the target suture device is in a first targeted position prior to receiving the first input; and
in response to a second input received from the user input device, store second data in the data store indicating a position of the automated suture fixture, the automated suture fixture having been at least partially manually manipulated so that the target suture device is in a second targeted position prior to receiving the second input.
12. The suturing assistance system of claim 11 , wherein the controller is further configured to:
generate the first data at least in part by capturing position information indicative of the first targeted position; and
generate the second data at least in part by capturing position information indicative of the second targeted position.
13. The suturing assistance system of claim 11 , wherein the controller is further configured to adjust a position of the automated suture fixture to arrive at the first targeted position or the second targeted position in response to positioning information received from the user input device.
14. The suturing assistance system of claim 11 , wherein the user input device includes a foot pedal.
15. The suturing assistance system of claim 11 , wherein the automated suture fixture comprises an articulation arm and a holder component.
16. The suturing assistance system of claim 15 , wherein a transition from the first targeted position to the second targeted position includes a rotation of the holder component about an axis of the holder component.
17. A suturing assistance system comprising:
an automated suture fixture comprising a plurality of motorized actuator devices and a suture target holder, the automated suture fixture being configured to position a target suture device mounted to the holder;
a camera system including a camera configured to generate an image of the target suture device;
a data store configured to store data indicating a position of the automated suture fixture, a position of the camera, or a focus setting of the camera;
a user input device configured to receive user input; and
a controller communicatively coupled to the user input device, the camera system, the data store, and the automated suture fixture, the controller configured to:
in response to a first input received from the user input device, store first data in the data store indicating a first fixture position of the automated suture fixture and a first camera position of the camera; and
in response to a second input received from the user input device, store second data in the data store indicating a second fixture position of the automated suture fixture and a second camera position of the camera.
18. The suturing assistance system of claim 17 , wherein first data further indicates a focus setting of the camera in the first camera position.
19. The suturing assistance system of claim 17 , wherein the camera remains focused on the target suture device with the automated suture fixture in the second fixture position without adjustment of a position or focus of the camera.
20. The suturing assistance system of claim 17 , wherein the controller is further configured to:
generate the first data at least in part by capturing position information indicative of the first fixture position, capturing position information indicative of the first camera position, and capturing focus information indicative of a first focus setting of the camera; and
