Summary of the invention:
The purpose of this utility model is to provide a kind of universal operation hand support, described this universal operation hand support to solve prior art in to the therapeutic process of some patients were or in the operation process that adopts special posture patient be difficult to obtain the technical problem rationally supporting.
This universal operation hand support of the present utility model, comprise that is put a hands plate, wherein, in the described bottom side of putting palm, be fixedly connected with a Connection Block, the lower end of described Connection Block is provided with a ballhead to downward-extension, described ballhead is connected with a ball cup downwards, in described ball cup, be provided with inner chamber, ballhead is arranged in described inner chamber, the internal diameter of the upper end open of inner chamber is less than the maximum gauge of ballhead, the lower end of ball cup has been threaded connection first screw rod, the first described screw rod is coaxial with ball cup, upper surface and the ballhead of the first screw rod are adjacent, the lower end of the first screw rod is connected with first turning handle, one side of ball cup is fixedly connected with one end of a support arm, the other end of described support arm is cylindrical and be connected with a holder, in described holder, be provided with a cylindrical hole, cylindrical one end of support arm is arranged in described cylindrical hole, in holder, be provided with a screwed hole, axially intersecting vertically of the axial and cylindrical hole of described screwed hole, screwed hole is communicated with cylindrical hole, in screwed hole, be provided with second screw rod, the excircle of one end end face of the second described screw rod and cylindrical one end of support arm is tangent, the other end of the second screw rod extends to outside holder and is connected with second turning handle, one side of holder is provided with a link slot.
Further, be provided with a guide rail in described link slot, described guide rail is fixedly installed on the bedstead side of an operation table.
Further, the end face of described link slot is C type.
Further, the length direction of described link slot and cylindrical hole is axial vertical.
Further, described support arm is U-shaped.
Further, described to put palm rectangular, puts in the upper side of palm and be provided with arc-shaped recess.
Operation principle of the present utility model is: in to patient's therapeutic process, holder is relative fixing with operation window, for example the link slot on holder is connected with the guide rail of the bedstead side of operation table.By regulating support arm and high and low position and the angle of holder, the angle of putting palm and ball cup, can set arbitrarily the locus of putting palm, make patient's arm obtain best support angle.The position that utilizes the first screw rod and the second screw rod lockable to put palm.
This utility model and prior art are compared, and its effect is actively with obvious.This utility model utilizes a universal hand support to connect and puts palm, in to patient's therapeutic process, holder is relative fixing with operation window, can be according to conditions of patients, operation position demand, regulate support arm and high and low position and the angle of holder, the angle of putting palm and ball cup, can set arbitrarily the locus of putting palm, make patient's arm obtain best support angle.The position that utilizes the first screw rod and the second screw rod lockable to put palm.
Accompanying drawing explanation:
Fig. 1 is the structural representation of universal operation hand support of the present utility model.
The specific embodiment:
Embodiment 1:
As shown in Figure 1, universal operation hand support of the present utility model, comprise that is put a palm 1, wherein, in the described bottom side of putting palm 1, be fixedly connected with a Connection Block 2, the lower end of described Connection Block 2 is provided with a ballhead 3 to downward-extension, described ballhead 3 is connected with a ball cup 4 downwards, in described ball cup 4, be provided with inner chamber, ballhead 3 is arranged in described inner chamber, the internal diameter of the upper end open of inner chamber is less than the maximum gauge of ballhead 3, the lower end of ball cup 4 has been threaded connection first screw rod 5, the first described screw rod 5 is coaxial with ball cup 4, the upper surface of the first screw rod 5 is adjacent with ballhead 3, the lower end of the first screw rod 5 is connected with first turning handle 6, one side of ball cup 4 is fixedly connected with one end of a support arm 7, the other end of described support arm 7 is cylindrical and be connected with a holder 8, in described holder 8, be provided with a cylindrical hole, cylindrical one end of support arm 7 is arranged in described cylindrical hole, in holder 8, be provided with a screwed hole, axially intersecting vertically of the axial and cylindrical hole of described screwed hole, screwed hole is communicated with cylindrical hole, in screwed hole, be provided with second screw rod 9, described one end end face of the second screw rod 9 and the excircle of cylindrical one end of support arm 7 are tangent, the other end of the second screw rod 9 extends to outside holder 8 and is connected with second turning handle 10, one side of holder 8 is provided with a link slot 11.
Further, be provided with a guide rail in described link slot 11, described guide rail is fixedly installed on the bedstead side of an operation table.
Further, the end face of described link slot 11 is C type.
Further, the length direction of described link slot 11 and cylindrical hole is axial vertical.
Further, described support arm 7 is U-shaped.
Further, described to put palm 1 rectangular, puts in the upper side of palm 1 and be provided with arc-shaped recess.
Operation principle of the present utility model is: in to patient's therapeutic process, holder 8 is relative fixing with operation window, for example the link slot on holder 8 11 is connected with the guide rail of the bedstead side of operation table.By regulating support arm 7 and high and low position and the angle of holder 8, the angle of putting palm 1 and ball cup 4, can set arbitrarily the locus of putting palm 1, make patient's arm obtain best support angle.The position that utilizes the first screw rod 5 and the second screw rod 9 lockables to put palm 1.
