The guiding retainer ring is fixed on two sides of an operating table by a fixing knob, and the height and position of the guiding retainer ring can be adjusted according to requirements. One or two semicircular guiding retainer rings can be chosen to fix to provide a dragging range with 180 degrees or 360 degrees. The adjustable hook is composed of a bottom seat and a lifting table. In using, the adjustable hook is lodged on the guiding retainer ring and connected with various shaped drag hooks by drag hook holes. For both the bottom seat and the lifting table adopts a positioning control structure composed of a push button, a coupled rod, a drive block, a reset spring and a positioning bead, and the hook handles of the drag hooks are all provided with corresponding positioning holes, not only can the length of the drag hooks be fine adjusted, but also the height of the lifting table of the adjustable hook can be adjusted.

Description

Adjustable surgery tractor

[affiliated technical field]

This utility model relates to a kind of operating theater instruments, particularly a kind of can meticulous adjusting length and the three-dimensional surgery tractor of adjusting direction.

[background technology]

Carrying out surgical operation particularly needs surgery tractor with abundant exposure surgical field of view when abdomen, pelvic part surgical operation.We can say there is not the exposure of surgical field of view, also just do not have surgical operation.Therefore, diversified surgery tractor is arisen at the historic moment.Wherein, a kind of surgery tractor is disclosed in the Chinese patent 99305618.0, it has advantage simple in structure, easy to use and that can tentatively reach the multi-direction adjusting drag hook angle on the two dimensional surface, yet its shortcoming is: 1. owing to adopt sectional type hook regulative mode, the spacing of each sections hook is bigger, therefore meticulous inadequately for the adjusting of drag hook length, such as elongating or shortening of each drag hook length, often in the actual operation process, cause drag hook to cross the inconvenience of pine or tension apart from about 2-3 centimetre; 2. because above-mentioned shortcoming, cause usually only to be used for drawing back of more tough tissues such as stomach wall in actual applications, and be used for the internal organs that liver etc. must softly draw back less; 3. only can tentatively reach on the two dimensional surface rather than the adjusting of the multi-direction drag hook angle of 3 D stereo; 4. when using a plurality of drag hook simultaneously, all drag hooks all can only be in the same plane, is difficult to satisfy the problem of drawing back of multi-level anatomical structure in the operation.These shortcomings are the insoluble problem of surgery tractor of present other kind equally.

[summary of the invention]

Be the function of further improving surgery tractor, the exposure of convenient surgical field of view, and the physical demands that reduces operative doctor, this utility model provide a kind of can meticulous adjusting length and the three-dimensional surgery tractor of adjusting direction.

The purpose of this utility model is achieved in that this surgery tractor is linked up with by guide securement circle, scalable and the drag hook three parts are formed.Described guide securement circle across and be fixed in the operating-table both sides, scalable hook lodge is on the circle body of guide securement circle, drag hook passes drag hook hole on the scalable hook and links up with scalable and socket-connect.

Further improvement of the utility model is: described guide securement circle is made of circle body, fixed arm, reference column and holder.Circle body can be semicircle or analogous shape, but is good with semicircle, and its cross section is circular; Have a plurality of reference columns on the circle body, preferably be equally spaced; The circle body two ends prolong the formation fixed arm downwards; Fixed arm passes holder, the latter adopt the fixed mode of knob make the guide securement circle across and be fixed in the both sides of operating-table.Two semicircle circle bodies constitute a circle, and 360 ° tractive angle can be provided, and also a semicircle circle body can only be installed as required simultaneously.

Further improvement of the utility model is: described scalable hook is combined by base and lifting platform.Both all have the location adjustment structure of being made up of button, trace, pushing block, back-moving spring and positioning bead.Lifting platform also has elevating lever and drag hook hole, and elevating lever and base socket-connect, and the drag hook pore volume is received the neck of hook of drag hook and moved within it; Also have hook and lift span on the base, the hook lodge is on the circle body of guide securement circle, and the elevating lever that lift span holds lifting platform moves within it.

Further improvement of the utility model is: described drag hook comprises a plurality of and multiple style, as abdominal retractor, S type drag hook and right-angle retractor etc., it all has following characteristics: 1. be divided into the neck of hook and gib head two parts, gib head can become difformity with the different designs of function, and neck of hook structure is fixed; 2. the neck of hook has a plurality of equidistant circular locating hole of vertical arrangement, the positioning bead tabling on the lifting platform of the latter and scalable hook.

Compared to prior art, this utility model is owing to adopted the guide securement circle of being with reference column, the drag hook that has locating hole, and the scalable hook structure that both couple together is made up of base and lifting platform with this, so can realize: 1. the three-dimensional regulation of drag hook angle; 2. the meticulous adjustment of drag hook length; 3. when using a plurality of scalable hooks and drag hook simultaneously, can realize that tractive on a plurality of horizontal planes is with the satisfied requirement of organizing tractive at many levels; 4. need not rely on tension force antagonism that drag hook is fixed, but thereby both tough tissues of tractive, but also tractive delicate tissue.
