대표청구항 ▼

1. A medical instrument, comprising: a shaft comprising a threaded portion on a distal end of the shaft and at least one slot on the distal end of the shaft;a handle connected to the shaft;a tool insert receivable in the shaft, comprising: a tool portion including a bearing with at least one protrusion for engagement with the at least one slot to prevent rotation of the tool portion relative to the shaft;a collar on a proximal side of the bearing and rotatable relative to the tool portion, the collar comprising threads that correspond to the threaded portion of the shaft; andan elongated member for engagement with the handle for actuation of the tool portion. 2. The medical instrument of claim 1, wherein the shaft further comprises two slots formed between four protrusions on the distal end of the shaft. 3. The medical instrument of claim 2, further comprising that each protrusion includes at least one surface inclined at an angle relative to the longitudinal axis of the shaft at its distal end. 4. The medical instrument of claim 1, wherein the tool insert further comprises a ball attached at a proximal end of the elongated member for engaging with the handle and the handle further comprising an opening for engaging with the ball. 5. The medical instrument of claim 4, wherein the opening is a keyhole opening for accepting and retaining the ball that is moveable between a retaining position and an accepting position. 6. The medical instrument of claim 5, wherein the handle further comprises an actuation assembly which receives a proximal end of the elongated member and in which the keyhole opening is disposed, and wherein the keyhole opening is moveable in a direction perpendicular to the longitudinal axis of the portion of the elongated member disposed in the actuation assembly. 7. The medical instrument of claim 6, further comprising that the keyhole opening is biased in the retaining position. 8. The medical instrument of claim 1, wherein the shaft further comprises a rotation member on its proximal end for rotating the shaft and the tool insert relative to the handle, the rotation member being moveable along the longitudinal axis of the shaft at the portion of the shaft that is connected to the handle. 9. A medical instrument, comprising: a shaft comprising a threaded portion on a distal end of the shaft and at least one slot on the distal end of the shaft;a handle connected to the shaft, comprising: a retaining member comprising an opening and being moveable between a retaining position and an accepting position;a tool insert receivable in the shaft, comprising:a tool portion including a bearing with at least one protrusion for engagement with the at least one slot to prevent rotation of the tool portion relative to the shaft;an elongated member including a ball on a proximal end thereof for engaging with the opening; anda collar on a proximal side of the tool portion and rotatable relative to the tool portion, the collar comprising threads that correspond to the threaded portion of the shaft;wherein the retaining member permits the handle to exert force on the elongated member along a longitudinal axis thereof for actuation of the tool portion. 10. The medical instrument of claim 9, wherein the handle further comprises an actuation assembly in which the retaining member is disposed and which receives the proximal end of the elongated member and wherein the retaining member is moveable in a direction perpendicular to the longitudinal axis of the portion of the elongated member disposed in the actuation assembly. 11. The medical instrument of claim 10, wherein the opening is a keyhole opening including an accepting portion sized larger than the ball and a retaining portion sized smaller than the ball. 12. The medical instrument of claim 11, wherein when the retaining member is in the retaining position, the retaining portion of the opening is aligned with the longitudinal axis of the portion of the elongated member disposed in the actuation assembly and wherein when the retaining member is in the accepting position, the accepting portion is aligned with the longitudinal axis of the portion of the elongated member disposed in the actuation assembly. 13. The medical instrument of claim 12, wherein the retaining member is a rod and is biased in the retaining position. 14. The medical instrument of claim 9, wherein the shaft further comprises two slots formed between four protrusions on the distal end of the shaft. 15. A medical instrument, comprising: a shaft comprising a threaded portion on a distal end of the shaft and at least one slot on the distal end of the shaft;a handle connected to said shaft, comprising: a retaining member comprising an opening and being moveable between a retaining position and an accepting position;a tool insert receivable in the shaft, comprising: a tool portion including a bearing with at least one protrusion for engagement with the at least one slot to prevent rotation of the tool portion relative to the shaft;a collar on a proximal side of the tool portion and rotatable relative to the tool portion, the collar comprising threads that correspond to the threaded portion of the shaft; andan elongated member including a ball on a proximal end thereof for engaging with the opening;wherein the retaining member permits the handle to exert force on the elongated member along a longitudinal axis thereof for actuation of the tool portion. 16. The medical instrument of claim 15, wherein the shaft further comprises two slots formed between four protrusions on the distal end of the shaft. 17. The medical instrument of claim 16, further comprising that each protrusion includes at least one surface inclined at an angle relative to the longitudinal axis of the shaft at its distal end. 18. The medical instrument of claim 15, wherein the handle further comprises an actuation assembly in which the retaining member is disposed and which receives the proximal end of the elongated member and wherein the retaining member is moveable in a direction perpendicular to the longitudinal axis of the portion of the elongated member disposed in the actuation assembly. 19. The medical instrument of claim 18, wherein the opening is a keyhole opening including an accepting portion sized larger than the ball and a retaining portion sized smaller than the ball. 20. The medical instrument of claim 19, wherein when the retaining member is in the retaining position, the retaining portion of the opening is aligned with the longitudinal axis of the portion of the elongated member disposed in the actuation assembly and wherein when the retaining member is in the accepting position, the accepting portion is aligned with the longitudinal axis of the portion of the elongated member disposed in the actuation assembly. 21. The medical instrument of claim 20, wherein the retaining member is a rod and is biased in the retaining position.
