Abstract

The invention discloses a retractor frame for the lithotomy position operation. The retractor frame comprises a big chuck, a small chuck and two arc draw hooks with half-moon-shaped chutes. The upper surface of the retractor frame is of a plane structure. The lower surface of the retractor frame is of a point-like round ball structure. The middles of outer rings of the two chucks are provided with knurled fastening screws. Clamping grooves are arranged on a border of the retractor frame at intervals and are used for fixing clamping bead chain draw hooks. The small chuck extends outwards to form two forkheads. Countersunk head locking screws and butterfly nuts which cannot be screwed out are arranged on the forkheads. The two arc draw hooks are provided with the half-moon-shaped chutes. The half-moon-shaped chutes are used for positioning the arc draw hooks. Round mouths are arranged in the half-moon-shaped chutes of the two arc draw hooks and are used for ensuring the arc draw hooks to be sleeved in. The retractor frame can be disinfected at a high temperature under high pressure. Not only is the cost of the operation reduced, but also the retractor frame is convenient to maintain. The retractor frame has popularization value.

Description

The calculi position operation retracts frame

Technical field

The present invention 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 successful key factor of operation, and the calculi position surgical patient is lain on the back, and patient people's operation of all can't standing more can not many people be carried out the sterile working, is difficult to carry out effective surgery.

Summary of the invention

For addressing the above problem; The present invention provides a kind of frame that retracts that makes things convenient for the calculi position operation, utilizes patient posture to fix, and cooperates card pelletron 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 waiting time of operation and hemorrhage to greatest extent.

The present invention realizes through following technical scheme:

A kind of suitable calculi position operation retract frame, comprise a big chuck, a little chuck and two arcuation drag hooks that the semilune chute is arranged; Retracting above the frame is planar structure, is point-like ball structure below, and the annular knurl trip bolt is arranged in the middle of the big or small chuck outer ring; Frame whenever just has a draw-in groove at a distance from a segment distance; Lesser calorie dish extension has two jaws, the countersunk head lock-screw is arranged on the jaw and can not twist wing nut, and two arcuation drag hooks all have semi-moon shaped chute and round mouth.

Beneficial effect of the present invention is:

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

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

The specific embodiment

Below in conjunction with accompanying drawing, the present invention is further specified.

Like Fig. 1, be to retract shelf structure figure, comprise big chuck 1 and draw-in groove 9; Be used to the fixing of card pelletron drag hook, lesser calorie dish 2 is used to the fixing of card pelletron drag hook and arcuation drag hook, two annular knurl trip bolts 3 with draw-in groove 9; Being used for arbitrarily adjustment retracts the evolution of 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 the wing nut on the countersunk head lock-screw 4 can not be back-outed, and guarantees operation safety; Arcuation drag hook 6 is used for fixing patient's two crotch; Drag hook chute 7 is used to regulate 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.

Like Fig. 2, be arcuation drag hook sketch map, arcuation drag hook 6, drag hook chute 7, round mouth 8.

Like Fig. 3, be the work sketch map that retracts frame, the calculi position operation; Patient's shape of lying on the back is converted into 90 ° of right angles with big chuck 1 with lesser calorie dish 2, with two intermediary annular knurl trip bolts 3 lockings in chuck outer ring; Little chuck is lain in patient's lower abdomen, and big chuck is unscrewed the wing nut 5 on the countersunk head lock-screw 4 then perpendicular to patient's perineal position; With the crotch that is placed on patient about two arcuation drag hook 6 lower ends branches, the round mouth 8 on the semilune chute 7 of upper end is aimed at wing nuts 5 and is put down, and the arcuation drag hook 6 that is inserted in is taken out tightly along semilune chute 7; Wing nut 5 is tightened, retracted frame like this 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 pelletron drag hook 11 down by standing state, retracts operative incision 12, is stuck in then 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 move for weight reduction is convenient again.

The present invention retracts frame and processes with rustless steel, and rustless steel is to use one of the most general and safe material, and available autoclave sterilization not only reduces the expense expenditure of operating room but also maintains easily, and meets medical apparatus and instruments basic concept safely and effectively.
