Connector for connecting medical tool and positioning module

Abstract

A connector for linking a medical tool to a positioning module includes: a first base, a second base, a positioning connecting part, and a detachable bushing. The second base is openable and closable relative to the first base, and together they define an accommodating space. The positioning connecting part is disposed on a first side of the first base and is configured outside the relative opening and closing movement path of the second base. The detachable bushing is disposed in the accommodating space and defines a clamping space. This connector allows surgeons to quickly and easily link medical tools to the positioning module.

Claims

1. A connector for connecting a medical tool and a positioning module, comprising: a first base; a second base, which is openable and closable relative to the first base and together with the first base defines an accommodating space; a positioning connection portion disposed on a first side of the first base, the positioning connection portion being configured outside the relative opening and closing movement path of the second base; and a removable bushing disposed in the accommodating space to define a clamping space, wherein the removable bushing includes two magnetic bushing components, which are magnetically attracted to the first base and the second base respectively, and the two magnetic bushing components are magnetically attracted to each other to jointly define the clamping space.

2. The connector for connecting a medical tool and a positioning module as described in claim 1, wherein the detachable bushing is provided with a plurality of screw holes, and the first base and the second base are provided with a plurality of through holes corresponding to the plurality of screw holes.

3. The connector for connecting a medical tool and a positioning module as described in claim 1, wherein the removable bushing includes two bushings, each bushing having a dovetail tenon for engaging with a dovetail groove of the first seat and a dovetail groove of the second seat, respectively.

4. The connector for connecting a medical tool and a positioning module as described in claim 3, wherein each of the bushings has a positioning bead configured to protrude from and retract from the surface of the dovetail tenon, and the dovetail groove of the first seat and the dovetail groove of the second seat each have a positioning hole corresponding to the positioning bead.

5. The connector for connecting a medical instrument and a positioning module as described in claim 1, wherein the clamping space has a longitudinal direction and the removable bushing has a first abutment to restrict displacement of the medical instrument along the longitudinal direction.

6. The connector for connecting a medical tool and a positioning module as described in claim 5, wherein the first base has a second abutment to limit the reverse displacement of the medical tool along the longitudinal direction.

7. The connector for connecting a medical tool and a positioning module as described in claim 1, wherein the second body is pivotally connected to a second side of the first body.

8. The connector for connecting a medical tool and a positioning module as described in claim 1 or 7, further comprising a locking part disposed on the second base, the locking part being configured to be lockable to the first side of the first base.

9. The connector for connecting a medical tool and a positioning module as described in claim 8, wherein the locking part includes a pin and a spring, the pin being disposed on the second base and used to connect to the first base, and the spring connecting the pin.

10. The connector for connecting a medical tool and a positioning module as described in claim 9, wherein the locking portion further includes a rotating handle connected to the pin, the rotating handle being used to change the orientation of the pin relative to the second seat, the second seat being configured such that, with the pin in a specified orientation relative to the second seat, the second seat allows the pin to retract into the second seat.

11. The connector for connecting a medical tool and a positioning module as described in claim 10, wherein the end of the pin away from the rotating handle is provided with a head, and the second body is provided with a socket of a shape matching the head, wherein the head is opposite the socket in the specified orientation, and the head and the second body do not interfere with each other.

12. The connector for connecting a medical tool and a positioning module as described in claim 8, wherein the locking part includes a rotating handle, a rotating post, and a spring, the rotating handle being connected to one end of the rotating post, the rotating post being disposed on the second base and used to connect to the first base, and the spring abutting against the second base and the rotating handle; wherein, The first base has a positioning protrusion facing the rotating column. The surface of the rotating column has a spiral groove, which is configured to allow the positioning protrusion to slide so that the rotating column rotates relative to the first base. The spiral groove has a reverse section so that the positioning protrusion is positioned in the reverse section.
