The lhotomy position surgery traction-to-open support is characterized in that: the upper surface of the traction-to-open support has a planar structure; the lower surface of the traction-to-open support has a point-shaped ball structure; Knurling fastening screws are provided between the outer rings of two chucks. The frame is provided with a channel section every certain distance for fixing a chucking bead chain draw hook. Two fork heads extend out from the small chuck. Each fork head is provided with a countersink locking screw and a butterfly nut. The two arc-shaped draw hooks are respectively provided with a halfmoon-shaped chute for positioning the arc-shaped draw hook. The halfmoon-shaped chutes of the two arc-shaped draw hooks are respectively provided with a circular port for sleeving the arc-shaped draw hook. High-temperature and high-pressure disinfection can be performed on the traction-to-open support. Not only is expense expenditure of the operating room reduced, but also maintenance is facilitated. The lthotomy position surgery traction-to-open support has high popularization value.

Description

Retractor frame for lithotomy position operation

Technical field

This utility model relates to a kind of apparatus of convenient operation, particularly a kind of frame that retracts that makes things convenient for the calculi position operation.

Background technology

Fully exposing that operative incision broadens one's vision is one of key factor of successful surgery, and the calculi position surgical patient is lain on the back, the operating doctor people operation of all can't standing, and more impossible many people carry out the sterile working, are difficult to effectively perform the operation.

Summary of the invention

For addressing the above problem, this utility model provides a kind of frame that retracts that makes things convenient for the calculi position operation, utilize patient posture to fix, cooperate card bead chain drag hook tractive to open operative incision, operative incision is fully exposed, enlarge patient's the visual field, not only omit patient assistant but also save patient's muscle power, reduced to greatest extent waiting time of operation and hemorrhage.

This utility model is to realize by following technical scheme:

A kind of applicable calculi position operation retract frame, comprise a large chuck, a little chuck and two arcuation drag hooks that the semilune chute is arranged, it is characterized in that described retracting above the frame is planar structure, the below is point-like ball structure, the size chuck has the annular knurl trip bolt in the middle of the outer ring, and frame just has a draw-in groove every a segment distance, and lesser calorie dish extension has two jaws.

Described lesser calorie dish extension has two jaws, and countersunk head lock-screw and wing nut are arranged on the jaw.

On described two arcuation drag hooks semi-moon shaped chute and round mouth are arranged all.

The described frame that retracts is made with rustless steel.

The beneficial effects of the utility model are:

When (1) implementing the calculi position operation, in narrow and small operating room, the people can't standing state under, cooperate and open otch with card bead chain drag hook tractive, operative incision is fully exposed, enlarge patient's the visual field, not only omitted patient assistant but also save patient's muscle power, reduced to greatest extent waiting time of operation and hemorrhage.

(2) reduce the expense of operating room and maintaining easily.

The specific embodiment

Below in conjunction with accompanying drawing, this utility model is described further.

Such as Fig. 1, to retract shelf structure figure, comprise large chuck 1 and draw-in groove 9, be used for the fixing of card bead chain drag hook, lesser calorie dish 2 is used for the fixing of card bead chain drag hook and arcuation drag hook with draw-in groove 9, two annular knurl trip bolts 3, be used for adjusting arbitrarily the evolution that retracts frame, countersunk head lock-screw 4 is arranged on the jaw and can not twist wing nut 5, it is to guarantee that small articles is not omitted in the art that wing nut on the countersunk head lock-screw 4 can not be back-outed, guarantee operation safety, arcuation drag hook 6 is used for fixedly patient's two crotch, drag hook chute 7 is used for regulating the fixedly distance of the crotch region of patient, and round mouth 8 is used for fashionable wing nut and the countersunk head lock-screw of passing through of arcuation drag hook cover, and ball 10 structures are to alleviate weight and the conveniently moving that retracts frame.

Such as Fig. 2, be arcuation drag hook schematic diagram, arcuation drag hook 6, drag hook chute 7, round mouth 8.

Such as Fig. 3, it is the work schematic diagram that retracts frame, the calculi position operation, patient's shape of lying on the back, large chuck 1 is converted into 90 ° of right angles with lesser calorie dish 2, with annular knurl trip bolt 3 lockings in the middle of two chuck outer rings, little chuck is lain in patient's lower abdomen, then large chuck unscrews the wing nut 5 on the countersunk head lock-screw 4 perpendicular to patient's perineal position, is placed on patient's crotch about two arcuation drag hook 6 lower ends are divided, round mouth on the semilune chute of upper end is aimed at wing nut 5 and is put down, the arcuation drag hook 6 that is inserted in is taken out tightly along the semilune chute, wing nut 5 is tightened, retract like this frame and just be the shape of standing like the legs of a tripod and be completely fixed.The frame that retracts that fixes just can be in narrow and small operating room space, the people can't use card bead chain drag hook 11 under the standing state, retract operative incision 12, then be stuck in the draw-in groove 9 that retracts frame, operative incision just can fully expose like this, not only can omit patient's assistant but also can save patient's muscle power, to greatest extent the waiting time of minimizing operation and hemorrhage, improve operation safety.Point-like ball 10 structures are for weight reduction makes things convenient for again mobile.

This utility model retractor frame for lithotomy position operation is made with rustless steel, and rustless steel is to use one of general and the safest material, and available autoclave sterilization not only reduces the expense expenditure of operating room but also maintains easily, and meets the effective basic concept of Safe of Medical Device.
