Description

The operation self-retaining retractor

This utility model relates to a kind of operation self-retaining retractor.

Any operation must just can be carried out after good appearing obtaining, and epigastrium relies on manpower to retract and often is difficult to obtain to appear fully because internal organs such as liver, board are dirty, esophagus, stomach is hidden in behind the rib under the diaphram arched roof deeply.Especially for some complicated operation, rely on artificial traction not only to be difficult to obtain satisfied and persistent art open country, also a large amount of muscle power and energy that consume operative doctor.And tight during artificial drag hook, the time pine, unbalance stress, the often process even the quality of influence operation.The existing mechanical drag hook, structure heaviness, complexity are used, all inconvenience of operation, can not arbitrarily regulate and control continuously, and retract the direction that can not comply with otch well, easily cause abdominal wall tissue to be pulled and cause postoperative pain etc.Existing pull device, unreasonable structure, surgical staff is mistake latch rifle and cause release in operation easily, retracts mouthful malfunctioningly suddenly, very easily causes contingency, and the safety of use is lower.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provides a kind of simple in structure, and is easy to use, can comply with cut-out direction to retract automatically, and the degree of retracting is step-less adjustment arbitrarily, safe and reliable operation self-retaining retractor.

The purpose of this utility model can reach by following measure:

A kind of operation self-retaining retractor comprises drag hook 15 and the lead 8 that is attached thereto, and its special character is: described lead 8 links to each other with adjusting device; Described adjusting device comprise be arranged on the support 5, rotating reel 3, described lead 8 is wound on the reel 3, handgrip 1 and gear 7 all are arranged on the central shaft of reel 3, the front end of ratchet 20 is stuck on the gear 7, the rear end of ratchet 20 links to each other with pin 21, and pin 21 is arranged on the support 5 by axle 22, and described pin 21 rotates with axle 22 and cooperates, spring 19 1 ends are fixed on the pin 21, and the other end is fixed on the support 5.

On the drag hook 15 of the present utility model anti-slip open-work 23 can be set.

Support 5 of the present utility model comprises two support plates 6,11 that reel 3 can be set, and support column 10, two support plates 6,11 of being located at 6,11 of two stands are fixed on the pedestal 18.

Pedestal 18 of the present utility model is a prism, and described two support plates 6,11 are individually fixed in its both sides, and pedestal 18 bottoms are provided with the groove 17 that can be arranged on the pillar 16.

The lead 8 of art utility model can lead to clip wheel 14 is connected with drag hook 15.

The accompanying drawing drawing is described as follows:

Fig. 1 is the structural representation of this utility model adjusting device;

Fig. 2 is an overall structure sketch map of the present utility model:

Fig. 3 is provided with the structural representation of the drag hook of anti-slip open-work for this utility model.

Down and will the utility model is described in further detail in conjunction with the accompanying drawings:

Referring to Fig. 1～2, this utility model is mainly by drag hook 15, and lead 8 and adjusting device constitute.Adjusting device comprises handgrip 1, and it is fixed on the central shaft of reel 3 by nut 2.The central shaft two end supports of reel 3 can rotate on the support plate 6,11 of both sides.Be provided with support column 10 between two support plates 6,11,, be convenient to be provided with reel 3 to keep the spacing of 6,11 of two support plates.Support plate 6,11 is individually fixed in pedestal 18 both sides, constitutes support 5.Pedestal 18 can be multiedge cylinder, is advisable with cuboid.Adjusting device is arranged on the pillar 16 by the groove 17 of pedestal 18 lower ends, and pedestal 18 can freely rotate on pillar 16.Pillar 16 lower ends can be fixed on the operation table.One side of the close handgrip 1 of reel 3 is provided with gear 7, and gear 7 is fixed on the central shaft of reel 3.Can make gear 7 forward or reverse by handgrip 1.Lead 8 is wound on the reel 3, and the one end is fixed in the circular groove 9 on the reel 3, and fixing by trip bolt 4, the other end links to each other with drag hook 15.Ratchet 20 rear ends are connected with pin 21, and pin 21 is its control crank.Pin 21 is arranged on the pedestal 18 by axle 22, and pin 21 can rotate around axle 22.The front end of ratchet 20 is stuck on the gear 7, dials with it to change to cooperate.Pin 21 is provided with back-moving spring 19, and an end of spring 19 is fixed on the pin 21, and the other end is fixed on the pedestal 18.Push the outer end of pin 21 downwards, spring 19 is compressed, and the ratchet 20 that links to each other with pin 21 upwarps, and out-of-gear 7 rotates counterclockwise gear 7 by handgrip 1, and then gear 7 rotates with reel 3, can loosen lead 8.Decontrol pin 21, under spring 19 restoring force effects, ratchet 20 front ends are stuck on the gear 7, and reel 3 can only clockwise rotate, and tightens up lead 8, thus the dynamics that retracts of 15 pairs of otch of scalable drag hook.Lead 8 links to each other with drag hook 15 rear ends by clip wheel 14, and lead 8 can be fixedly welded on the clip wheel 14, or is placed on the clip wheel 14, uses lead end socket 13 with lead head sealing.Drag hook 15 front ends are gib head 12, on the gib head 12 anti-slip open-work 23 can be set, and see Fig. 3.The stainless steel cable of plastic packaging that lead 8 of the present utility model is convenient to sterilize, sterilize with employing is advisable.

The utility model compared with prior art has following advantage:

1. compactness simple in structure, dexterous, firm; Easy to use, save manpower;
