Pelvic cavity bilobate drag hookTechnical field
This utility model relates to and keeps the open apparatus of wound, specifically is the pelvic cavity bilobate drag hook that a kind of medical science surgical operation uses.
Background technology
Cystectomy is the important Urology Surgery operation method of the many bladder diseases of treatment.The blood supply of bladder mainly is to be derived from hypogastric important branch-bladder upper, middle and lower tremulous pulse, and these tremulous pulsies enter bladder by the bladder side ligament.In bladder excision process, cutting off the bladder side ligament is necessary step, and when handling the bladder side ligament, for avoiding damaging the pelvic tissue organs such as rectum that close on, appearing the art open country clearly is the key of operation.When appearing the bladder side ligament, press down rectum with finger along the bladder side ligament by the assistant usually, then, the patient uses operating forceps gradation clamp, pricks the bladder side ligament from disconnected, seam.Because operating field is darker, the surrounding tissue organ is more, and the aforesaid operations process is comparatively complicated, and especially the assistant presses down rectum with finger along the bladder side ligament, more makes operative space narrow and small, has increased the difficulty of operation, has increased labor intensity again.
Chinese patent 2167681 discloses a kind of " bladder retractor ", and it is made of drag hook and handle.Drag hook is convexly curved, its length and full bladder deep equality, and handle end has a small half of serpentine bending, is convenient to control firmly.This utility model is compared with existing serpentine drag hook, has the wild exposure of art fully, easy to operate advantage, shorten operating time effectively, reduced patient's misery and amount of bleeding, not only be suitable for operation on bladder, and operation on prostate and the terminal operation application of ureter, effect is also good.
Chinese patent 2600059 discloses a kind of " multiple wing sheet pelvic cavity drag hook ", and it is to be combined by fin (1) and handle (2).Fin (1) is sleeved on handle (2) threaded foremost " protruding " the shape step successively, and is fan-shaped and opens, and fixes and regulates with nut (3).Compared with prior art, simple in structure, easy to operate, serviceability is good, can satisfy the exposure requirement at operation on pelvis position, the sectorial area size can be regulated, and is easy to promote.
Summary of the invention
This utility model be exactly for solve clamp in the cystectomy, from disconnected, when seam is pricked the bladder side ligament, darker because of operating field, the surrounding tissue organ is more, the narrow and small problem that is not easy to perform a surgical operation of operative space, and a kind of pelvic cavity bilobate drag hook is provided.
This utility model is realized by following technical scheme.
A kind of pelvic cavity bilobate drag hook, the handle that comprises an end, and be formed with pressing plate successively at the handle other end, elongated narrow and be divided into the leaf portion of 2 leaves arranged side by side through the joint portion trouble, whole side-looking is " it " font, and the pressing plate between handle and the leaf portion, joint portion to leaf portion are formed with reverse arc-shaped bend respectively.
Described pelvic cavity bilobate drag hook, the leaf portion that its joint portion trouble arranged side by side is divided into 2 leaves is nose circle head breadth leaf portion, rounded head narrow leaf portion, is equidistant gap between wide leaf portion and the narrow leaf portion.
She Ji this utility model like this, when enlarging operative space as far as possible, can realize that the bladder side ligament obtains to appear more clearly, enlarged operative space, rectum outside the operation open country, is avoided histoorgan such as rectum around the damage by the retaining of safety, makes from disconnected bladder side ligament and can finish smoothly under the visual field clearly, both shorten operating time, reduced manpower again.

The specific embodiment
Below in conjunction with drawings and Examples this utility model is described in detail.
A kind of pelvic cavity bilobate drag hook, thehandle 1 that comprises an end, and be formed withpressing plate 2 successively athandle 1 other end, elongated narrow 3 and through thejoint portion 4 troubles are divided into theleaf portion 5 of 2 leaves arranged side by side, whole side-looking is " it " font, and thepressing plate 2 betweenhandle 1 and theleaf portion 5,joint portion 4 toleaf portion 5 are formed with reverse arc-shaped bend respectively.
Described pelvic cavity bilobate drag hook, theleaf portion 5 that its joint portion trouble arranged side by side is divided into 2 leaves is nose circle headbreadth leaf portion 6, rounded headnarrow leaf portion 7, isequidistant gap 8 betweenwide leaf portion 6 and thenarrow leaf portion 7.
Described pelvic cavity bilobate drag hook, itspressing plate 2 centrage both sides become symmetrical arc, and are formed with byplate hole 10 in the center of circle, not only can alleviate weight of the present utility model, and increase the frictional force when pushing, and skid when avoiding firmly.Skid in order to prevent to push, pressingplate 2 faces also can form and vertical many grooves of centrage (not shown),
Described pelvic cavity bilobate drag hook, itshandle 1 is the tabular of button-head, andhandle 1 spoke narrows down theformation handle hole 10 identical with its profile on thehandle 1 gradually towards pressing plate 2.Like this, promptly alleviated weight of the present utility model, can be convenient to the patient again and firmly grip.
Described pelvic cavity bilobate drag hook, pressingplate 2 between itshandle 1 and theleaf portion 5 andjoint portion 4 are formed with reverse R30mm arc-shaped bend respectively, form the bending of R120-140mm cancave cambered surface betweenjoint portion 4 to theleaf portion 5 on the face.Make it to form smooth " it " word shape of transition circle slip-stream, the pelvic cavity that enters preferably is operated.
Described pelvic cavity bilobate drag hook, the button-head breadth of itshandle 1 is identical with the breadth of the diameter ofpressing plate 2,joint portion 4 andleaf portion 5.
Described pelvic cavity bilobate drag hook, this drag hook are the platy structures that adopts the stainless steel materials integrated punching to form.The long 300mm of She Ji this utility model like this, the wideest 40mm of breadth, the wide 10mm of isthmus, gap spacing 10mm, the 93 * 10mm of narrow leaf portion, the wide leaf 93 * 20mm of portion, the arc circle R20mm of pressing plate both sides, the shoulder of joint portion and isthmus junction is the circular arc of R20mm, and the whole edge of this utility model of making smoothness is in order to avoid damaged tissue.
During use, after the patient finishes fully dissociating of bladder side ligament, preparing before disconnected bladder side ligament, with the operating forceps tractive bladder that makes progress, hand-heldhandle 1 is placed this utility model along the bladder side ligament, with the bladder side ligament place that this utility model front end is wide, 8 li of gap between thenarrow leaf portion 6,7, and this utility model put to pushing away to the front lower place, can be according to different patient's pelvic cavity degree of depth and radian, adjust the pelvic cavity bilobate drag hook angle and the degree of depth, utilizewide leaf portion 6 that rectum,narrow leaf portion 7 are blocked in the pelvic diaphragm muscle tissue outside the operating field respectively.The bladder side ligament is fully appeared.Use operating forceps gradation clamp, prick the bladder side ligament from disconnected, seam.
