Abstract
A surgical tool control apparatus according to an embodiment comprises: a housing; and a control assembly including a frame connected to the housing, and a first roller module, a second roller module, and a third roller module which are installed on the frame, wherein the second roller module can horizontally move toward the first roller module so that a first surgical tool can be held between the first roller module and the second roller module, and can horizontally move toward the third roller module so that a second surgical tool can be held between the second roller module and the third roller module.
Core Innovation
The invention is a surgical tool control apparatus that includes a housing and a control assembly with a frame connected to the housing. On the frame, a first roller module, a second roller module, and a third roller module are installed, and the control assembly selectively grips either a first surgical tool or a second surgical tool by movement of the second roller module.
The second roller module moves toward the first roller module so that the first surgical tool is gripped between the first roller module and the second roller module, and moves toward the third roller module so that the second surgical tool is gripped between the second roller module and the third roller module. The roller modules include a roller plate and a rotatably provided roller member, and the second roller module includes a vertical movement portion that vertically moves an upper roller plate relative to a lower roller plate.
The apparatus further includes a horizontal movement portion configured to move the roller plate horizontally in accordance with a horizontal movement driving motor, a horizontal movement lead screw, and a horizontal movement lead screw nut. Clamping portions are provided so that a first surgical tool is clamped when it is not gripped by the first and second roller modules, and a second surgical tool is clamped when it is not gripped by the second and third roller modules.
Claims Coverage
The document contains one independent claim with dependent claims that add roller-module structure, actuation, and additional gripping support. Across the claims, the inventive features cover selective gripping by an intermediate roller module, roller-plate and roller-member construction, horizontal and vertical movement actuation, and additional clamping portions, with expanded independent control in arrangements using additional roller modules.
Selective tool gripping by movement of an intermediate roller module
A control assembly selectively grips either the first surgical tool or the second surgical tool by movement of the second roller module, where the second roller module moves toward the first roller module to grip the first surgical tool between the first and second roller modules and moves toward the third roller module to grip the second surgical tool between the second and third roller modules.
Roller plate with rotatably provided roller member
Each roller module includes a roller plate connected to the frame and a rotatably provided roller member.
Horizontal movement portion using motor, lead screw, and lead screw nut
A horizontal movement portion includes a horizontal movement driving motor, a horizontal movement lead screw, and a horizontal movement lead screw nut that engages the lead screw so that a roller plate is moved horizontally in accordance with lead screw rotation.
Vertical movement of upper and lower roller plates
A roller plate includes a lower roller plate connected to the frame and an upper roller plate positioned above the lower roller plate, and the second roller module includes a vertical movement portion that vertically moves the upper roller plate relative to the lower roller plate.
Additional clamping portions for tools when not gripped by roller module pairs
A first clamping portion clamps the first surgical tool when it is not gripped by the first and second roller modules, and a second clamping portion clamps the second surgical tool when it is not gripped by the second and third roller modules.
Independent control using additional roller modules and tool pairs
Independently controls each of the first and third surgical tools when corresponding roller module pairs grip those tools, and independently controls each of the second and fourth surgical tools when corresponding roller module pairs grip those tools.
The independent claim centers on selectively gripping one of two surgical tools by moving an intermediate second roller module toward adjacent roller modules. Dependent features specify roller-module substructure with a roller plate and rotatably provided roller member, actuation of horizontal movement via a motor, lead screw, and lead screw nut, vertical movement via upper and lower roller plates, added clamping portions to hold tools when not gripped, and expanded independent multi-tool control using additional roller modules.
Stated Advantages
Independent control of multiple tools and applicability to complicated PCI.
Documented Applications
Use in complex PCI (complicated PCI), where the apparatus selectively grips and controls surgical tools.
