Detailed description of the invention
In order to make those skilled in the art person better understand this utility model scheme, below in conjunction with the accompanying drawing in this utility model embodiment, clear, complete description is carried out to the technical scheme in this utility model embodiment.
As shown in Figure 1 and Figure 2, a kind of nail taking out apparatus in orthopaedics, comprises base 1, and the upper surface of base 1 is connected with a pad 12, and pad 12 adopts the soft materials such as sponge to make, and the upper surface of pad 12 is set to the curved concave surface in cross section.The design of concave surface of pad 12 upper surface and the shape of the limbs of human body adapt, more comfortable when when making to get nail, the limbs of patient are placed in pad 12, and also can not feel well when the fixing head 41 on top is fixed it.Base 1 affixed with support arm 2 bottom, crossbeam 3 is positioned at above base 1, and described base 1 axis and crossbeam 3 axis being parallel are arranged.Get nail piece 5 to comprise and get oncomelania bar 51, get nail slide block 52, motor 53 and get ailhead 54, get nail piece 5 and be located on crossbeam 3, and can move freely on crossbeam.Mainly through arranging realization as follows, the second chute 8 of two strips is offered in the both sides of crossbeam 3, get nail slide block 52 and tighten up that nut 9 is mobilizable to be placed in this second chute 8 then by both sides, thus make to get nail piece and can move on crossbeam, slide block can be fixed on assigned address during fastening nut.This central part position of getting nail slide block 52 offers a tapped through hole, gets oncomelania bar 51 and is placed in this tapped through hole, and by screw thread between the two, making to get oncomelania bar 51 can move up and down relative to getting nail slide block 52.A handle 13 is connected with on the top of getting oncomelania bar 51, turning handle 13, both can control screw rod 51 by handle 13 to rotate, screw rod 51 is rotated in tapped through hole, thus move up and down relative to getting nail slide block 52, after having added handle 13, increase the operations area between hands on screw rod 51 top, make operation more simple and efficient.And on handle 13, be provided with anti-slip veins, make, in the process being controlled screw rod 51 rotation by handle 13, increase the frictional force before handle 13 and hands, thus turning handle 13 to be more prone to, and the phenomenon of skidding not easily occurs.
The fixture 4 be made up of fixing head 41 and outrigger shaft 42 is positioned at below crossbeam 3, above base 1.Crossbeam 3 is provided with rectangular hollow bulb, and the width of rectangular hollow bulb is equal with getting the width following closely slide block 52, thus above-mentioned corresponding nail slide block 52 of getting moves in this hollow bulb.Accordingly, the fillet rectangle hollow groove 43 that the hollow bulb that fixing head 41 is also provided with shape, size and crossbeam 3 matches, after the limbs getting patient during nail are fixing by fixing head 41, the position that needs on limbs carry out getting nail can be exposed from hollow groove 43, while serving good fixed effect, make to get nail more efficient.One end of fixing head 41 is fixedly connected with an outrigger shaft 42, a wherein end of outrigger shaft 42 offers a screwed hole, the first chute 6 of a strip is then offered at the sidepiece of support arm 2, the nut of locking nut 7 is placed in the outer surface of support arm 2, thread spindle passes in the screwed hole of the first chute 6 and outrigger shaft 42, and fixing head 41 can be fixed on a certain position of support arm 2 by fastening nut.
The bottom of getting oncomelania bar 51 is provided with a cylindrical cavity 10, the outer wall of this cavity is provided with screw thread, be provided with the recess 11 that shape, size and a cavity matches getting ailhead 54 top, the inwall of this recess 11 is provided with screw thread, is connected between cavity 10 with recess 11 by screw-thread securing.And can change the ailhead 54 of getting of bottom when performing the operation.Motor 53 is placed in this cavity 10, and is connected to bottom motor 53 and gets ailhead 54.
Support arm 2 top is cylinder bottom is cuboid, and the top of support arm 2 is arranged with sleeve 21, and the length of sleeve 21 is set to 1/2 of the length being greater than support arm 2, is less than or equal to the length of support arm 2.All offer screwed hole in the two side of sleeve 21, the axis of two screwed holes is positioned at same straight line, is all placed with fastener 22 in screwed hole, and fastener can adopt and tighten up nut.The top of sleeve 21 is provided with the first protuberance 23, second protuberance 24 and the first recess 25, first recess 25 between the first protuberance 23, second protuberance 24.The central part position, end of crossbeam 3 is connected with connecting axle 31, and the end opens of connecting axle 31 has a through hole, and the position the first protuberance 23 and the second protuberance 24 corresponding to through hole all offers screwed hole.When connecting axle 31 is placed in the first recess 25, connecting axle 31 through hole and the first protuberance 23 and the second protuberance 24 on screwed hole overlapping, by a thread spindle 32 through in three above-mentioned holes, sleeve lateral wall is stretched out at two ends, overlap top nut 33 in the part of the thread spindle 32 stretching out sleeve lateral wall, such crossbeam 3 can do relative to support arm 2 and have rotated up and down.Bottom the first recess 25, be also provided with a baffle plate 251 perpendicular to support arm 2, it can play interception function to the rotation up and down of crossbeam 3, and when crossbeam turns to support arm 2 upright position, crossbeam 3 just can not rotate.
Concrete operations are as follows:
Upper and lower rotating beam, crossbeam is turned to outside support arm 2 with support arm 2 upright position, turn on locking nut 7 afterwards, fixture 4 moved to the first chute 6 top.After limbs being put on pad 12 Deng patient, fixing head 41 being moved down on limbs, after finding the correct position of fixed limb, tightens locking nut 7 and fixture 4 is fixed on this position, complete limbs of patient and fix.Then, upper and lower rotating beam 3 again, crossbeam is turned to inside support arm 2 with support arm 2 upright position, unclamp the fastener 22 on sleeve 21 afterwards, left-right rotation crossbeam 3, make the axis of crossbeam 3 can with get that to follow closely position crossing.That turns on slide block 52 both sides afterwards tightens up nut 9, and moving slider 52 need get the position of nail to limbs, tightens afterwards and tightens up nut 9, makes slide block 51 be fixed on this position, can not be subjected to displacement getting in nail process.Select handle 13 to control to get oncomelania bar 51 afterwards to move down, the ailhead in limbs of patient is inserted and gets in ailhead, then electric motor starting, nail is taken out.
Obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of this utility model protection.
