Abstract

The invention discloses a multi-layer retractor frame which comprises a frame body shaped like the Arabic numeral '8', two arc drag hooks and four parallel drag hooks. The frame body shaped like the Arabic numeral '8' is composed of a large chuck and a small chuck. The multi-layer retractor frame is characterized in that the upper face of the retractor frame is of a plane structure, the lower face of the retractor frame is of a punctiform circular structure, knurling fastening screws are arranged in the middles of the outer circles of the two chucks, clamping grooves are formed in the frames of the large and small chucks at certain intervals, and six pile feet are arranged on two outward-extending fork heads of the small chuck and arranged at the three o'clock position, six o'clock position, nine o'clock position and twelve o'clock position of the large chuck respectively. According to the multi-layer retractor frame, the surgical incision epidermis can be retracted in all directions, the surgeon view field is enlarged, and the surgery is facilitated for the human tissue with the retracted surgical incision; the number of medical personnel is reduced, the multi-layer retractor frame can be disinfected at high temperature and high pressure, the incur expense of a surgery room is reduced, surgery safety is improved, and resources are saved for medical institutions.

Description

Multilamellar retracts frame

Technical field

The multilamellar that the present invention relates to a kind of convenient operation retracts frame.

Background technology

It is one of key factor of successful surgery that abundant exposure operative incision is broadened one's vision, and during calculi position operation, patient need lie on the back, and because operating room is narrower and small, people stands and can have any problem, and being therefore difficult to hold many people carries out sterile working, implements effectively to perform the operation.

Summary of the invention

For solving the problems of the technologies described above, the present invention has designed a kind of operation and has retracted frame by multilamellar, comprise a large chuck and 8 cabinet frames that lesser calorie dish forms, two arcuation drag hooks and four parallel drag hooks, utilize patient's position, by two arcuation drag hooks that retract frame, firmly at fixing patient's two hips, ground floor leads scalloping epidermis with card bead chain drag hook, the second layer leads scalloping tissue with parallel drag hook, so just can effectively perform the operation.

The present invention is that a kind of multilamellar realizing by following technical scheme retracts frame, comprise a large chuck and 8 cabinet frames that lesser calorie dish forms, two arcuation drag hooks and four parallel drag hooks, what it is characterized in that retracting frame is plane structure above, be point-like circular configuration below, in the middle of two described chuck outer rings, there is annular knurl trip bolt, the frame of size chuck just has a draw-in groove every a segment distance, and there are six footings 3,6,9,12 positions on two jaws of lesser calorie dish extension and on large chuck.

The footing that described multilamellar retracts on frame 8 cabinet frames is comprised of lock-screw and wing nut, and the wing nut on footing can only be tightened and unclamp but and can not screw out.

Described multilamellar retracts on the L shaped arcuation drag hook of frame semilune chute, has round mouth in chute.

Described multilamellar retracts on the L shaped parallel drag hook of frame chute, has round mouth in chute.

The point-like circular configuration that described multilamellar retracts below frame forms with steel ball.

Beneficial effect of the present invention is: during calculi position operation, in narrow and small operating room, people stands under difficult state, with card bead chain drag hook, retract the epidermis of operative incision, with parallel drag hook, retract tissue, operative incision is fully exposed, convenient operation, not only omit patient assistant but also saved patient's muscle power, and reduced to greatest extent waiting time of operation and hemorrhage.

The specific embodiment

Below in conjunction with accompanying drawing, the present invention will be further described.

As Fig. 1, multilamellar retracts shelf structure figure, comprise large chuck 21, lesser calorie dish 22, two footings fixing for arcuation drag hook on lesser calorie dish 22 jaws, two annular knurl trip bolts 23, for adjusting the evolution that retracts frame, six footings on 8 cabinet frames are comprised of lock-screw 24 and wing nut 25, wing nut 25 on footing can only be tightened and unclamp but and can not screw out, to guarantee that in art, accessory is difficult for omitting, L shaped arcuation drag hook 26 is fixed for the crotch patient, round mouth 27, for the fashionable footing that passes through of arcuation drag hook cover, chute 28, for regulating fixing distance, draw-in groove 29, for fixing of card bead chain drag hook, L shaped parallel drag hook 30, be used for retracting tissue 34, be fixed on 3 on large chuck, 6, 9, on 12 footings, steel ball 31 for point-like circular configuration, weight and convenient movement that retracts frame in order to alleviate.

As Fig. 2, L shaped arcuation drag hook schematic diagram, shape arcuation drag hook 26, drag hook chute 27, round mouth 28.

As Fig. 3, L shaped parallel drag hook schematic diagram, parallel drag hook 30.

As Fig. 4, multilamellar retracts the work schematic diagram of frame, calculi position hands art, patient's shape of lying on the back, by large chuck 21 and lesser calorie dish 22 folding right angles in 90 °, by 23 lockings of the annular knurl trip bolt in the middle of two chuck outer rings, little chuck is lain in to patient's lower abdomen, large chuck is perpendicular to patient's perineal position, then unscrew the wing nut 25 on two footing lock-screws 24 on lesser calorie dish 22 jaws, divide left and right to be placed on patient's crotch two L shaped arcuation drag hook 26 lower ends, the wing nut 25 that round mouth 27 is aimed at footing puts down, taking out of semilune chute 28 is tight, wing nut 25 on lesser calorie dish 22 jaws is tightened fixing, retracting like this frame is just the shape of standing like the legs of a tripod and has been completely fixed.The frame that retracts fixing just can be in narrow and small operating room space, people cannot use card bead chain drag hook 32 under standing state, retract operative incision epidermis 33, be fixed in draw-in groove 29, then use L shaped parallel drag hook 30, retract operative incision tissue 34, with the round mouth of flat L shaped row drag hook 30, aim at footing and put down, smooth groove is drawn to correct position, with wing nut 25, is tightened fixingly, and operative incision epidermis and tissue just can fully expose like this.

Multilamellar of the present invention retracts frame and makes with rustless steel, both can be in surgical operation the comprehensive operative incision epidermis that retracts, can retract the tissue of operative incision again, expand the convenient operation in the patient visual field, can also reduce personnel's outfit.Multilamellar retracts the available autoclave sterilization of frame, and the disbursement of operating room is reduced, and medical institutions have not only been increased to operation safety but also saved resource.
