Description

Minimally Invasive Surgery device for spreading with microcam and light source

Technical field

This utility model relates to a kind of Minimally Invasive Surgery device for spreading.

Background technology

Conventional surgical operation is with drawing structure that otch is drawn back, undergo surgery under the situation by Light on head for surgery or shadowless lamp illumination again, the transmission of operation record and operation process if desired, need to finish by hand-held or shadowless lamp video camera, operative incision drawn back by auxiliary doctor continue firmly to finish, cause fatigue easily, and auxiliary doctor can take the footprint of operating-table, to such an extent as to image operator doctor's operation is carried out, if shadowless lamp illumination in the small incision surgery process, can cause the surgical field of view illuminance not enough, if use the head lamp illumination, because head is mobile, can cause light source to shine rocking of zone, usually if desired the record or the transmission operation process, need hand-held camera or with video camera as on operation shadowless lamp and the head lamp, but the record or image transmitted rock owing to artificial reason causes easily.

Summary of the invention

The purpose of this utility model is: a kind of surgical operation device for spreading of realizing from key lighting and the transmission of operation video is provided, promptly has the Minimally Invasive Surgery device for spreading of microcam and light source.

Concrete structure improves as follows:

Minimally Invasive Surgery device for spreading with microcam and light source, comprisering support 4, be arranged with 4-8clamper 2 on thering support 4,coaxial ratchet 15 and thegear 14 of being provided with inclamper 2 tops,ratchet 15 bottom correspondences are provided withcam 18, andpull bar 1 is located atclamper 2 tops, rack andpinion 14 corresponding matching ofpull bar 1 bottom surface,pull bar 1 is positioned atring support 4 footpaths upwards, and pullbar 1 the inner is connectingsupport 6, and support 6 front ends are provided with the vertical operation gin pole of stretching down 11.

The front portion of one of themclamper 2 is connecting fore-stock 5, and the front end of fore-stock 5 is provided with miniature 9 vertically downward;

Wherein fore-stock 5 front ends of anotherclamper 2 are provided withphotographic head 19 vertically downward.

Miniature 9 is a led light source.

Miniature 9 is for having the led light source of battery case.

Describedphotographic head 19 is the CCD photographic head.

Be provided with angle adjuster between describedphotographic head 19 and the fore-stock 5.

This device has the advantage of following several respects:

When 1, this utility model is used to perform the operation, need not special doctor's drag hook and draw back surgical wound, the operation gin pole draws back wound easily, and is easy to operate, and the size of wound is stable, can not change convenient operator operation doctor's operation because of operator are tired.

2, the fore-stock front end setting miniature vertically downward of clamper realizes that illumination is stable, can not rock because of the rocking of carrier of illumination.

3, the fore-stock front end of clamper is provided with video camera and can be intactly the process record of operation be got off, and can not should be artificial reason and rock, and the image of picked-up does not have any blocking, and realizes taking clearly and completely.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described by embodiment.

Embodiment 1:

Referring to Fig. 1 and Fig. 2, Minimally Invasive Surgery device for spreading with microcam and light source, comprisering support 4, be installed with 6clampers 2 on thering support 4,clamper 2 is fixed on thering support 4 byset lever 3, andclamper 2 tops are coaxially installed withratchet 15 andgear 14, and correspondence is equipped withcam 18 on theclamper 2 ofratchet 15 bottoms, on 18 on thecam spring 16 is housed, 18 front ends of cam are equipped with lockingspring 17;

L shapedpull bar 1 is loaded onclamper 2 tops, rack andpinion 14 corresponding matching ofpull bar 1 bottom surface,pull bar 1 is positioned atring support 4 footpaths upwards, pullbar 1 the inner is connectingsupport 6 byscrew 13, support 6 front ends are equipped with the vertical operation gin pole of stretching down 11, betweenoperation gin pole 11 and thesupport 6adjustor 8 are housed;

The front portion of one of themclamper 2 is connecting fore-stock 5, and the front end of fore-stock 5 is equipped with miniature 9 vertically downward, and miniature 9 is a led light source, andfocus adjustment knob 10 is equipped with in its front portion, and its rear portion is connectingoptical fiber 12;

Wherein fore-stock 5 front ends of anotherclamper 2 are equipped withphotographic head 19 vertically downward,photographic head 19 is the CCD photographic head, betweenphotographic head 19 and the fore-stock 5angle adjuster 7 is housed,photographic head 19 is connecting sevenheart yearns 20, sees Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 6.
