U.S. Pat. No. 7,003,827

  SUMMARY OF THE INVENTION It is a main object of the present invention to provide a clamp device capable of performing a positioning operation and an attaching / detaching operation quickly and easily and maintaining good safety during use.

  A clamping device for solving the above-described problem includes a support base, a handle, a fastener, and a lock member. The handle is located at one end of the support. The fastener has a fastener upper portion, a slide portion, and a fastener lower portion. The upper fastener is secured to the top of the support. The slide portion is disposed on the support base, can be moved horizontally by the handle, and can move horizontally toward the support base, and has a slope at the tip end. The lower part of the fastener is disposed on the support base so as to be able to move up and down, and has a slope at the bottom. Since the slope of the slide portion comes into contact with the slope of the lower portion of the fastener, when the slide portion is moved by the handle, the slide portion raises the lower portion of the fastener from the release position to the tightening position. The lower part of the fastener reaching the fastening position sandwiches the rail of the operating table between the two by the upper part of the fastener. The locking member has a stopper, a restoring spring, and a rod-shaped locking portion. The stopper is disposed on the support base so as to be able to move up and down, and has a second positioning portion. The second positioning portion of the stopper and the first positioning portion of the slide portion correspond to each other. The restoring spring acts on the stopper and moves the stopper in the direction of the slide. The rod-shaped locking portion is disposed on the support base so as to be able to move horizontally, and is operated by the handle to act on the stopper between the locking position and the unlocking position. When the rod-shaped locking portion is set in the locking position, the stopper is pressed by the locking portion of the rod-shaped locking portion to stop the slide portion. At this time, the lower part of the fastener is maintained in the tightening position. When the rod-shaped locking part is set in the unlocking position, the stopper is released from the locking part of the rod-shaped locking part and moves the slide part horizontally. At this time, the clamp device according to the present invention is moved upward, and the lower part of the fastener is pushed by the rail contacting the lower part of the fastener and the upper part of the fastener, and the slide part is moved to the left to move the lower part of the fastener. Once lowered to the release position, the rails can be loosened.

  Due to the above-mentioned structural features, the attachment / detachment work of the clamp device according to the present invention can be performed with one hand, a safety function can be ensured, and a component can be prevented from coming off due to a human error. That is, the positioning operation and the attaching / detaching operation can be performed quickly and easily, and safety in use can be improved.

  If relatively preferred, the rail has an outer surface. The handle is arranged on the support base by the rotating shaft. Since the axial direction of the rotating shaft is perpendicular to the extending direction of the outer surface of the rail, it is possible to prevent the operation of the steering wheel from interfering with a surrounding person or object, thereby improving the operational convenience.

  If relatively preferred, the handle has an arcuate abutment surface. The slide has a passive plane. When the handle is lowered, the arc-shaped contact surface of the handle comes into contact with the passive plane of the slide portion, so that the handle can move the slide portion smoothly.

  If relatively preferred, the handle has a first bar and a second bar. The first bar and the second bar are located on the same side on the handle. The first bar is smaller in length than the second bar and lower in position than the second bar. The rod-shaped locking part has a locking part at one end, and has an upright part and a contact part at the other end. When the contact portion of the rod-shaped locking portion is moved by the first horizontal bar of the handle, the rod-shaped locking portion moves from the locking position to the unlocking position. When the upright part of the rod-shaped locking part is moved by the second horizontal bar of the handle, the rod-shaped locking part moves from the unlocked position to the locked position.

  Where relatively preferred, the support further comprises slots. The rod-shaped locking portion has a toggle member that is vertical to the upright portion. The toggle member is formed at one end of the rod-shaped locking part, is inserted into a slot of the support base so that it can reciprocate horizontally, and projects to the side facing the rail of the support base, so that it is convenient for unlocking with one hand. You can measure sex.

  If relatively preferred, the support further has an opening. The stopper has a protrusion. The protrusion of the stopper fits into the opening of the support base. The locking member further has a lever. The lever abuts against the side surface of the support base facing the rail, one end is fixed to the protrusion of the stopper, and the other end has a convex portion. The second safety function is to move the convex part of the lever by the toggle member of the rod-shaped locking part when the rod-shaped locking part is set in the locking position. When the rod-shaped locking part is set in the unlocking position, the convex part of the lever is released from the toggle member of the rod-shaped locking part, so that the stopper moves the slide part without obstructing.

  In a relatively preferred case, the support has a magnet inside. The handle has a slot. Since the magnet is fitted into the notch in the handle and attracts and stabilizes the handle, malfunction of the handle can be suppressed.

  The detailed structure, features, assembly or use of the clamp device according to the present invention will be clarified through the detailed description of the following embodiments. It is to be noted that the following detailed description and the embodiments presented by the present invention are merely examples for describing the present invention, and the claims of the present invention cannot be limited by those skilled in the art related to the present invention.

As shown in FIGS. 1 to 5, a clamp device 10 according to an embodiment of the present invention includes a support 20, a handle 30, a fastener 40, and a lock member 60.

  The support base 20 includes a front plate 21 and a rear plate 23. The front side plate 21 has a fitting groove 22 on the inner side surface. The rear plate 23 has a slot 24 formed at one end and an opening 25 formed at the center. The slot 24 and the opening 25 penetrate the inside and outside surfaces of the rear plate 23.

  The handle 30 is disposed at one end of the support base 20 by a rotation shaft 35, has a cutout 31 on a side surface facing the front side plate 21, and has a first horizontal bar 32 and a second horizontal bar 33 on a side surface facing the rear side plate 23. Having. The first horizontal bar 32 is smaller in length than the second horizontal bar 33 and lower in position than the second horizontal bar 33. The handle 30 further has an arc-shaped contact surface 34 adjacent to the second horizontal bar 33.

  The fastener 40 has a fastener upper portion 41, a slide portion 44, and a fastener lower portion 48.

  The fastener upper portion 41 is fixed to the top of the rear plate 23 of the support base 20 by a fastening member such as a screw, has a pair of upper jaws 42 at one end, and is connected to the holder 43 at the other end to be integrated. . A surgical auxiliary device, for example, a robot arm (not shown in the figure) is mounted on the holder 43.

The slide part 44 is disposed in the support base 20 and has a passive plane 45. When the passive flat surface 45 of the slide portion 44 is moved by the arcuate contact surface 34 of the handle 30, the slide portion 44 moves horizontally toward the support base 20. The slide portion 44 further has a slope 46 formed on the top and a first positioning portion 47 formed on the bottom.
As shown in FIG. 9, in the present embodiment, the first positioning portion 47 includes a plurality of concave grooves 472 arranged at intervals. Each concave groove 472 has a first plane 474 on a wall surface and a first slope 476 facing the first plane 474.

The fastener lower part 48 has a shaft 49, a lower jaw 50, and a slope 51. The shaft 49 is disposed on the support base 20 so as to be able to move up and down, and the top is connected to the lower jaw 50 to be integrated. The lower jaw 50 is exposed outside the support base 20. The slope 51 is formed at the bottom of the shaft 49.
As shown in FIG. 6A, since the slope 51 of the fastener lower portion 48 abuts the slope 46 of the slide portion 44, the horizontally moving slide portion 44 can raise the fastener lower portion 48.

  The lock member 60 has a stopper 61, a restoration spring 64, a rod-shaped locking portion 66, and a lever 71.

The stopper 61 is arranged on the support base 20 so as to be able to move up and down, and has a second positioning portion 62 on the top surface.
As shown in FIG. 9, in the present embodiment, the second positioning portion 62 includes a plurality of convex portions 622 arranged at intervals. The plurality of convex portions 622 are fitted into the concave grooves 472 of the first positioning portion 47 one by one, and have a second plane 624 and a second inclined surface 626 facing the second plane 624, respectively. The second plane 624 of the projection 622 abuts the first plane 474 of the concave groove 472. The second slope 626 of the convex portion 622 contacts the first slope 476 of the concave groove 472. Due to the structural features described above, the second positioning portion 62 of the stopper 61 and the first positioning portion 47 of the slide portion 44 correspond to each other. The stopper 61 further has a protrusion 63 at one end. The stopper 61 is fitted into the opening 25 of the rear plate 23 by the projecting portion 63, and the size of the projecting portion 63 is smaller than the opening 25 of the rear plate 23, so that the stopper 61 is not hindered when moving up and down.

  The restoring spring 64 (compression spring) has a leading end contacting the bottom surface of the stopper 61 and a distal end contacting the top surface of the support plate 65. Since the support plate 65 is fixed to the front side plate 21 by a fastening member such as a screw, the restoring spring 64 can generate elasticity for moving the stopper 61 in the direction of the slide portion 44.

The rod-shaped locking portion 66 is disposed on the support base 20 so as to be able to move horizontally, and has a fitting portion 67, a locking portion 68, an upright portion 69, a toggle member 70, and a contact portion 81. The fitting portion 67 is formed at the center of the rod-shaped locking portion 66 and fits into the fitting groove 22 of the front side plate 21. The locking portion 68 is formed at one end of the rod-shaped locking portion 66 and is located below the protrusion 63 of the stopper 61. The upright portion 69, the toggle member 70, and the contact portion 81 are formed at the other end of the rod-shaped locking portion 66.
As shown in FIGS. 4 and 5, the toggle member 70 and the contact portion 81 are perpendicular to the upright portion 69. The toggle member 70 of the rod-shaped locking portion is inserted into the slot 24 of the rear plate 23 and protrudes from the outer surface of the rear plate 23 (i.e., the side facing the rail 12 on the support 20, see FIG. 1).

  The lever 71 is in contact with the outer side surface of the rear side plate 23 (that is, the side surface facing the rail 12 on the support base 20; see FIG. 1), and has a fixing portion 74 and a convex portion 72. The fixing portion 74 is formed at one end of the lever 71 and is fixed to the projecting portion 63 of the stopper 61 by a fastening member such as a screw, so that the lever 71 can operate together with the stopper 61. The convex portion 72 is formed at the other end of the lever 71, and the second safety function is to abut on the toggle member 70 of the rod-shaped locking portion 66.

When performing the attaching operation, the handle 30 is turned to bring the first horizontal bar 32 of the handle 30 into contact with the contact portion 81 of the stick-shaped locking portion 66, thereby moving the stick-shaped locking portion 66 to the right. Since the handle 30 is operated by the rotation shaft 35, the first horizontal bar 32 comes into contact with the contact portion 81 of the rod-shaped locking portion 66 and then separates from the contact portion 81.
As shown in FIGS. 6A and 6B (the illustration of the lever 71 is omitted for convenience of explanation), the locking portion 68 of the rod-shaped locking portion 66 and the protruding portion 63 of the stopper 61 are displaced, that is, the rod-shaped locking portion 66 When reaches the unlock position P3, the stopper 61 can operate up and down. Subsequently, when turning the handle 30 to the left, the first horizontal bar 32 of the handle 30 is relatively short, so that even if the handle 30 is continuously rotated as shown in FIGS. It does not occur that the horizontal bar 32 comes into contact with the upright portion 69 of the rod-shaped locking portion 66 to interfere therewith. Subsequently, the handle 30 pushes the passive flat surface 45 of the slide portion 44 by the arcuate contact surface 34.
At this time, as shown in FIGS. 6C and 6D, since the stopper 61 is in a state where it can be moved up and down, the slide portion 44 can move to the right. The moving slide portion 44 pushes the second flat surface 624 of the second positioning portion 62 of the stopper 61 by the first flat surface 474 of the first positioning portion 47, and the stopper 61 is actuated together with the dual action of the slide portion 44 and the restoring spring 64. Reciprocate up and down. At the same time, the slope 46 pushes the slope 51 of the fastener lower part 48 to raise the fastener lower part 48 from the release position P1 (see FIG. 6a) to the tightening position P2 (see FIG. 6d). When the fastener lower part 48 rises to the fastening position P2, the operating table rail 12 can be sandwiched between the fastener upper part 41 and the both.
Subsequently, as shown in FIG. 6E, the handle 30 is turned clockwise, and the upright portion 69 of the rod-shaped locking portion 66 is pushed by the second horizontal bar 33 of the handle 30. At this time, since the second horizontal bar 33 of the handle 30 is relatively long, when the handle 30 is turned in the reverse direction, the second horizontal bar 33 of the handle 30 continuously contacts the upright portion 69 of the rod-shaped locking portion 66, and The locking unit 66 is continuously moved to the left.
As shown in FIG. 6F, the locking portion 68 of the rod-shaped locking portion 66 comes into contact with the projection 63 of the stopper 61, and the toggle member 70 of the rod-shaped locking portion 66 comes into contact with the convex portion 72 of the lever 71, that is, the rod-shaped locking. When the portion 66 reaches the locking position P4, the stopper 61 cannot operate up and down. At this time, the slide portion 44 cannot move as the stopper 61 stops. That is, the mounting operation is completed.

  In order to avoid malfunction of the handle 30 due to human error, a magnet 73 is arranged on the inner side surface of the front side plate 21 as shown in FIG. When the handle 30 is maintained in the initial state (see FIG. 6A), the magnet 73 fits into the cutout 31 of the handle 30 and attracts the handle 30 to stand still. After the mounting operation is completed, the axial direction A of the rotating shaft 35 is perpendicular to the extending direction of the outer surface 14 of the rail 12, so that the operation of the handle 30 and the surrounding people or objects do not interfere with each other. Can be.

  When performing the removal work, as shown in FIG. 6g, the toggle member 70 of the rod-shaped locking portion 66 is moved to the right with one hand to separate the toggle member 70 of the rod-shaped locking portion 66 and the convex portion 72 of the lever 71 at the same time. Then, the locking portion 68 of the rod-shaped locking portion 66 and the projecting portion 63 of the stopper 61 are separated. That is, the rod-shaped locking section 66 is moved to the unlocking position P3. Subsequently, the fixing portion 74 of the lever 71 is lowered with one hand. At this time, since the fixing portion 74 of the lever 71 and the extension 63 of the stopper 61 are collectively fixed, the stopper 61 descends together with the lever 71, compresses the restoring spring 64, and releases the stationary state of the slide portion 44. Subsequently, the holder 43 is lifted, and the fastener lower portion 48 is forcibly lowered by the rail 12 abutting between the fastener upper portion 41 and the fastener lower portion 48 to move the slide portion 44 to the left. When the fastener lower portion 48 is lowered to the release position P1 (see FIG. 6A), the rail 12 can be loosened and the removal operation can be performed.

The structures of the concave groove 472 of the slide portion 44 and the convex portion 622 of the stopper 61 are not limited to those described above, and may be changed.
As shown in FIG. 10, the concave groove 472 of the slide portion 44 has a first plane 474 and a first circular surface 478 facing the first plane 474. The convex portion 622 of the stopper 61 has a second plane 624 and a second arc surface 628 facing the second plane 624. The first plane 474 of the concave groove 472 of the slide part 44 and the second plane 624 of the convex part 622 of the stopper 61 abut each other. The first arc surface 478 of the concave groove 472 of the slide portion 44 and the second arc surface 628 of the convex portion 622 of the stopper 61 abut each other. With the above-described structural features, the first positioning portion 47 of the slide portion 44 and the second positioning portion 62 of the stopper 61 can exhibit a positioning effect corresponding to each other.

  In summary, the clamping device 10 according to the present invention can be attached and detached with one hand to ensure a safety function. In other words, it is possible to avoid the problem that parts are detached due to malfunction due to human error, perform the positioning operation and the attaching / detaching operation quickly and easily, and improve the safety in use.
