Description

Abdominal part is around drag hook

This utility model relates to a kind of medical apparatus and instruments that is used for abdominal operation.

At present, when carrying out the operation of abdominal part, need to hook the abdominal incision tissue of cutting open, or need a plurality of assistants to help to hold the abdominal incision tissue, internal organs are revealed, just conveniently undergo surgery with the monolateral drag hook that is supported on the bedstead.Above-mentioned this monolateral drag hook only catches on the monolateral tissue in operative incision place, easily the position of the whole health of patient is drawn mobilely, perhaps makes internal organs appear not good enough, is difficult to satisfy the requirement of operation technique.And adopt a plurality of assistants to assist waste of manpower.

Task of the present utility model is will provide a kind of can evenly catch on the tissue on both sides, operative incision place securely and keep the constant circumtractor of its openings of sizes.

Task of the present utility model is finished like this: it has two shelves, two crotches are installed on each shelf at least, all there is the straight rotating shaft of one section weak point at the two ends of each shelf, respectively there is a pedestal that has two parallel axis holes at the two ends of shelf, straight rotating shaft is inserted in the axis hole and can be rotated therein, also have the localizer that shelf can not be rotated in axis hole, this localizer is installed on the pedestal or straight roller end.

Because this utility model has two shelves that can rotate in the axis hole of pedestal, the localizer that shelf can not be rotated in axis hole is arranged again simultaneously, thereby when using this utility model to carry out abdominal operation, can make operative site otch two relative edges' tissue, can be subjected to the mutual application of force of positive interaction power and counteracting force, make stressed even, pull hook is firm, the incision opening is stable, and internal organs expose fully, make things convenient for operation technique; Assist assistant's number of pull hook incision tissue in the time of can reducing simultaneously operation; This utility model is particularly suitable for using when various large, medium and small type abdominal operation.

Be elaborated with drawings and Examples below.

Fig. 1 is the sketch map of an embodiment of this utility model.Fig. 2 amplifies triple cutaway view along the A-A line among Fig. 1.Fig. 3 is the cutaway view of another embodiment drag hook and shelf junction.Fig. 4 is the cutaway view of the third embodiment drag hook and shelf junction.Fig. 5 amplifies triple cutaway view along the B-B line among Fig. 1.Fig. 6 amplifies triple cutaway view along the C-C line among Fig. 1.Fig. 7 is the cutaway view of straight rotating shaft of another embodiment and pedestal junction.Fig. 8 is the cutaway view of straight rotating shaft and detachable pedestal junction.

With reference to accompanying drawing 1, present embodiment has the shelf 1 of two falcates, and the cross section of shelf material is ellipse or round rectangle preferably.Can 2 to 6 crotches 2 be installed according to its size on each shelf, all there is straight rotating shaft 3 one section weak point, co-axial at the two ends of each shelf, the two ends of shelf respectively have a pedestal 4 that the same end of two shelves is connected together again, two parallel axis holes 5 are arranged on the pedestal, and straight rotating shaft 3 is inserted in the axis hole and can be rotated therein.Also have a localizer 6 in the outside of pedestal 4, this localizer is actually a location-plate, and hole, two sides 7 is arranged above it.Straight rotating shaft 3 is slightly longer than pedestal 4, and its outer end is stretched out from axis hole 5 and square toes 8 are arranged.Hole, two of location-plate sides 7 is enclosed within on the square toes 8 of two straight roller end just, and shelf 1 can not be rotated in axis hole 5, thus two positions that two shelves are positioned at close up or launch to shakeout.

Also can prevent that as localizer shelf from rotating without location-plate, but as shown in Fig. 7 or Fig. 8: with holding screw 9.At this moment need process a milling flat 10 in straight rotating shaft 3, holding screw 9 is installed on the pedestal the corresponding axis hole of milling flat 5 places with straight rotating shaft, inwardly is screwed into holding screw and makes it to be pressed on the milling flat and can make shelf stop.

For making crotch 2 flexible easily when colluding the draw cut mouth and organize, with the position of adjusting crotch with collude the elasticity of drawing, can as depicted in figs. 1 and 2 cross section increase portion 11 be made at the position that crotch is installed on the shelf 1.There is a straight hole 12 in this cross section increase portion, the axis of straight hole and shelf plane parallel, on the straight-arm 13 of crotch 2 zigzag tooth bar 14 is arranged, straight-arm 13 can insert straight hole 12 and slippages therein, and this cross section increase portion 11 also has one with spring 15 returns and the ratchet 16 that acts on mutually with tooth bar 14.When ratchet and tooth bar engagement, the hook portion 17 that pushes hard crotch 2 can make crotch retraction backward.Pull it,, can upwards draw the head 18 above the ratchet, make the claw of its below and tooth bar break away from engagement for sliding ratchet (shown in Fig. 1 to Fig. 4 is exactly this ratchet).For the swing type ratchet, then need push the ratchet head and swing by it, make its claw and tooth bar break away from engagement.The hook portion 17 of crotch 2 will do slightly widely and slightly to palintrope, the surface is slick and sly, has so not only caught on the tissue of organizing but also can not scratch easily.The shape of crotch 2 can do the curved greatly formula of growth foot, also can make the little curved formula of short foot.

The cross section of straight hole 12 can be circular, also can be rectangle, and the shape of crotch straight-arm 13 will adapt with the shape of straight hole 12, promptly also is circle or rectangle.For prevent that the crotch straight-arm from rotating in straight hole, when its cross section is circle, a spline groove along axis to be arranged on the straight-arm, need there be one piece of alignment pin that stretches in the spline groove at the straight hole place of shelf.

For ease of making, the cross section increase portion 11 of shelf can be made independent part one drag hook shelf in addition, as shown in Figure 3 and Figure 4, shelf 1 is attached thereto by hole 19 on this part (drag hook shelf) or groove 20.When adopting way shown in Figure 4 to make shelf 1 and groove 20 on the drag hook shelf is connected, anti-skidding tooth 21 need be arranged at the exterior arc surface of shelf and the side of groove on the other side.This structure was was both conveniently installed and used, and was convenient to again unpick and wash.

In order to be more conducive to adjust the size of shelf opening, but also shown in the image pattern 8 like that: on the basis of structure shown in Figure 7, pedestal made a detachable left side, right two halves 4A, 4B, the straight rotating shaft 3 of two shelves is inserted respectively in the axis hole of two halves pedestal, with the screw rod 23 that has the shaft shoulder 22 the two halves pedestal is coupled together, wherein the screw 24 of left half axle frame 4A screws with the thread segment of screw rod left end, the unthreaded hole 25 of right axle shaft frame 4B and the optical axis section of screw rod right-hand member are movingly, and with two round nuts 26 back of the body tightening positions, the outer end refills the handwheel 27 in order to rotary screw 23, rotation hand wheel can make screw rod rotate, thereby adjusts the relative position of two halves pedestal.

During use, select suitable shelf and crotch (perhaps also having drag hook shelf) according to the position and the otch size of operation earlier, and they are installed, make two shelves become to launch to shakeout shape, with localizer they are fixed then and keep shakeouing shape, the reuse crotch catches on incision tissue, and slightly firmly pulls crotch backward, make it to contract backward, thereby the jail is colluded by incision tissue.After using up localizer is unclamped, two shelves are pulled back closed up state,, be convenient to put into box and preserve to dwindle its volume.
