Abstract

An operation support device having a surgical instrument unit and a surgical instrument unit support section, includes: an intermediate member connected to the surgical instrument support section and configured to hold the surgical instrument unit; a shielding member having a hole portion engaged with the intermediate member; and a driving force supply unit installed at the surgical instrument support section. A first space and a second space are formed by an assembly constituted by the shielding member and the intermediate member engaged with the hole portion as a boundary. The intermediate member is connected to the surgical instrument support section at a side of the first space, and holds the surgical instrument unit at a side of the second space. The driving force supply unit and the surgical instrument support section are disposed in the first space.

Claims

1. An operation support device having a surgical instrument unit and a surgical instrument unit support section configured to detachably support the surgical instrument unit, the operation support device comprising:

a sterilizable intermediate member rotatably connected to the surgical instrument support section and configured to detachably hold the surgical instrument unit;

a sterilizable drape having at least one hole portion, the hole portion being engaged with the intermediate member; and

a driving force supply unit installed at the surgical instrument support section and configured to supply a driving force to the surgical instrument unit via the intermediate member,

wherein a first space and a second space are formed by an assembly constituted by the drape and the intermediate member engaged with the hole portion of the drape as a boundary,

the intermediate member is detachably connected to the surgical instrument support section at a side of the first space,

the intermediate member detachably holds the surgical instrument unit at a side of the second space, and

the driving force supply unit and the surgical instrument support section are disposed in the first space.

2. The operation support device according to claim 1, wherein, as at least the intermediate member is rotated, a rotary driving force is supplied to the surgical instrument unit.

3. The operation support device according to claim 1, wherein at least a pair of hole portions are provided, and

the intermediate member has a through-hole portion, into which the surgical instrument unit is inserted, provided to pass through the pair of hole portions and constituting a part of the second space.

4. The operation support device according to claim 3, wherein the through-hole portion has a detachable sterilized sheath.

5. The operation support device according to claim 1, wherein the driving force supply unit has at least a linear driving force supply unit configured to advance and retract a drive shaft section in a certain direction to supply a linear driving force,

the intermediate member has at least a linear driving transmission shaft section movably installed in the same direction as the drive shaft section, and

the surgical instrument unit is driven by the linear driving force received from the linear driving transmission shaft section.

6. The operation support device according to claim 1, wherein the intermediate member and the surgical instrument unit are detachably installed to advance and retract with respect to the hole portion in a certain axial direction.

7. The operation support device according to claim 6, wherein the intermediate member and the driving force supply unit are detachably installed in the axial direction.

8. The operation support device according to claim 1, wherein the drape is provided with a frame member joined with the drape, and

the hole portion on which the intermediate member is mounted is formed at an inner circumferential portion of the frame member.

9. The operation support device according to claim 8, wherein the frame member joined with the drape is detachably installed with respect to the driving force transmission section.

10. The operation support device according to claim 1, wherein

the drape is provided with a coated housing joined with the drape, and

the hole portion through which the intermediate member is capable of passing is formed at the coated housing.

11. The operation support device according to claim 10, wherein the coated housing joined with the drape is detachably installed with respect to the driving force transmission section.

12. An assembly method of an operation support device having a surgical instrument unit and a surgical instrument unit support section configured to detachably support the surgical instrument unit, wherein the operation support device comprises:

a sterilizable intermediate member rotatably connected to the surgical instrument support section and configured to detachably hold the surgical instrument unit;

a sterilizable shielding member having at least one hole portion engaged with the intermediate member; and

a driving force supply unit installed at the surgical instrument support section and configured to supply a driving force to the surgical instrument unit via the intermediate member,

the assembly method comprising;

a shielding member disposition process of disposing the shielding member to cover the driving force supply unit and the surgical instrument support section;

a first connecting process of engaging the hole portion of the shielding member with the intermediate member to form an assembly, positioning the driving force supply unit and the surgical instrument support section in a first space using the assembly as a boundary, and detachably connecting the intermediate member and the surgical instrument support section in a side of the first space; and

a second connecting process of detachably holding the intermediate member and the surgical instrument unit in a side of a second space opposite to the first space using the assembly as a boundary.
