Detailed Description

The present invention is described in detail below with reference to the attached drawings:

as shown in fig. 1, 2, 3, and 4, a minimally invasive light source visual retractor includes a base 1 made of a material meeting the standards of medical surgical equipment, a retractor 2 extending forward from the bottom of the base 1, and a light source visual component (not shown in the drawings) mounted on the base 1, where the light source visual component is a commonly-used device for acquiring the surgical field in a wound, the device having a front light source and a light guide structure or a high definition camera, and the front end of the retractor 2 is a tilted arc-shaped curved surface for poking out a visual space for the light source visual component below the retractor, and the tilted structure can limit tissue organs poked out by the retractor from slipping and affecting the surgical field and space. 2 bottoms of drag hook are equipped with expanding unit, expanding unit includes base 31, adjust the expansion piece 33 of seat 32 and two symmetries, base 31 passes through bolted connection rigid coupling in 2 bottoms of drag hook, base 31 is passed to the mode of the horizontal threaded connection of screw rod 34, the front end swivelling joint of screw rod 34 is on adjusting seat 32, it realizes along drag hook 2 extending direction adjustable connection in base 31 to adjust seat 32 through the rotation effect of screw rod 34, the end of expansion piece 33 is connected in base 31 through rivet or round pin axle movablely, the middle part of expansion piece 33 and adjust and be connected through connecting rod 35 movablely between the seat 32. Before the expansion in the operation wound, expansion piece 33 draws in drag hook 2 below, inserts the wound with this drag hook after, and operating personnel can make the relative base 31 of regulation seat 32 forward movement through twisting screw 34, and the connecting rod motion between each part of expansion device drives expansion piece 33 promptly and opens to both sides and realize opening of wound department fat, tissue or viscera and provide space and field of vision for the operation this moment. Because the number of turns that the screw rod was twisted is controllable, the aperture that opens between two expansion pieces 33 also can carry out corresponding regulation according to the operation position of difference and operation demand, the power that supports its aperture after expansion piece 33 opens simultaneously is provided by screw rod 34 and screw thread frictional force, the reaction force that the human tissue provided is not enough to press it back, so can realize stable expansion effect, and then realize controllable, stable expansion in the wound under the effect of a structure, and its simple structure.

In this embodiment, correspond on base member 1 and the base 31 and be equipped with the first passageway 11 and the second passageway 12 that set up side by side, the visual subassembly of optics wears to locate in the first passageway 11 to through the route of the visual subassembly of the spacing visual subassembly of optics of first passageway 11, with its 2 the place ahead of directional drag hook, guarantee that it observes the operation field of vision, make the pipeline of the visual subassembly of optics simultaneously hidden the drag hook can not make the pipeline contact wound when pulling open the operation wound, guarantee the cleanness of operation and the safety of wound, the parcel that realizes the visual subassembly of optics through setting up first passageway 11 makes the operating personnel can not touch the visual subassembly of optics when holding base member 1 removal drag hook, guarantees to walk the line and is not disturbed.

In this embodiment, 2 below of drag hook are equipped with the couple 13 that is located the base 31 front side, and couple 13 and the suspension of the visual subassembly front end of optics are realized to the visual subassembly releasable connection of optics, guarantee the stability of its installation, and then provide stable operation field of vision.

In this embodiment, a rigid (such as made of medical stainless steel) through pipe 14 is arranged in the second channel 12, and the safety of the patient is ensured by the smoke suction channel which can be used as a smoke discharge channel for discharging smoke generated by an electrotome and an electric coagulation forceps in an operation; and can also pass through and guide small tools such as an sampling forceps and the like to facilitate the operation of the operating personnel.

In this embodiment, the horizontal position of the expansion piece 33 is higher than that of the first channel 11 and the second channel 12, and the lower surface of the expansion piece extends downwards to form an enclosing part 36, and the enclosing part 36 is in an L-shaped cross section. When the expansion piece 33 is closed, it is located above the first and

second channels

11, 12, so that it can be completely received under the retractor 2 in a small space, while the enclosure 36 can receive the base 31 and the duct 14, the optical viewing element, by its opposite L-shaped enclosure. Therefore, when the drag hook 2 stretches into the wound, the whole sectional area is small, meanwhile, the part of the structure which is easily contacted with the human body of the patient is regular and tidy (is surrounded by the surrounding part 36), so that the smaller opening size can be selected when the operation wound is cut, the wound of the patient is reduced, the subsequent recovery effect of the patient is improved, and meanwhile, the possible damage of the contact between the drag hook and the wound to the wound can be reduced.

In this embodiment, the top of the base 1 is connected with a nut 15 detachably connected to the end portions of the first channel 11 and the second channel 12, and the nut 15 can seal the end portions when the channels are not used, so that the probability that dust, germs and the like in the outside air enter the wound through the channels is reduced, and the possible pollution problem caused by the fact that the channels are not used can also be reduced.

In this embodiment, the front end of the expansion piece 33 is a curved surface tilted upward, so that on one hand, the function of the expansion piece is the same as that of the drag hook 2, and on the other hand, the tilted angle and radian of the expansion piece are preferably the same as those of the drag hook 2, so that the expansion piece and the lower surface of the drag hook 2 are close to each other when the expansion piece is folded (as shown in fig. 3), the size of the wound is further reduced, the contact with the human body is reduced, and the possibility that the human body tissue is clamped by the drag hook 2 and the expansion piece 33.

In this embodiment, the base 1 extends forward to form an extension portion 16, and the extension portion 16 includes at least two portions that are opposite to each other in the vertical direction for holding, thereby providing a structure for the operator to hold comfortably and stably.

In this embodiment, the extension 16 that is located the top has the connecting portion 17 of indent with base member 1 within a definite time, and this structure sets up with the form of circular arc indent and makes can make the structure of external form also can be stable realization drag hook effect in connecting portion 17 department with the stores pylon card through structures such as external stores pylon, even adopt artifical the gripping, the probability that operating personnel's forefinger reduction slippage also can be held to this structure.

The above embodiments are only described for the preferred embodiments of the present invention, and are not intended to limit the concept and scope of the present invention, and the various modifications and improvements made by the ordinary person in the art without departing from the design concept of the present invention all fall into the protection scope of the present invention.
