Description

A kind of female ureter bracket extractor

Technical field

The utility model belongs to the field of medical instrument technology more particularly to a kind of female ureter bracket extractor.

Background technique

Damage and the formation of postoperative ureterostoma are one of the risk symptoms that gynaecology can often encounter in ureter art.According to urine output Pipe traveling feature, easy damaged part are predominantly located at pelvic cavity, including ureter is crossed and entered at blood vessel, below uterine artery inside and outside ilium On the outside of uterosacral ligament and at cardinal ligament, bladder inlet；The displacement of tumor of pelvis passage simultaneously, tumor-infiltrated, mullerianosis Disease, inflammation adhesion, the past operation on pelvis history etc. lead to topography level, ureter position change, and big section is free in gynaecology's art Ureter, the excessive connective tissue of removing, or ligatured too close to uterine artery root, ureter blood supply is damaged, is caused postoperative defeated Urinary catheter ischemic, necrosis, because coagulation or cutting cause ureter thermal damage etc. in the laparoscopic surgery being especially widely used at present, It is the reason of ureteral injury in gynecological surgery occurs.

Therefore, at present in clinical position, as preoperative evaluation need row radical hysterectomy, there are tumour passage infiltration or son Endometriosis and inflammation adhesion wait injury of ureter high risk condition again when, it is placed in bilateral ureteral in advance before gynecological surgery Bracket plays a supporting role in protection simultaneously to indicate that ureter traveling avoids damaging in art in more preferable art, avoids postoperative lack Postoperative ureterostenosis even ureterostoma caused by blood, necrosis, inflammation package etc..The ureter bracket of preventative merging is usual It needs to take out at 1 month or so after surgery, traditional pipe mode that takes is to enter urethra by cystoscope, looks at lower nipper clamp bilateral straight Ureter bracket " J " type tail end is extracted, but this mode needs to anaesthetize down using cystoscope, and process is cumbersome, it has not been convenient to, and pelvic cavity The postoperative female patient urethra local susceptibility of gynaecology increases, and patient is easily made to generate pain and discomfort, while postoperative pelvic tissue knot Structure changes, such as misoperation, and rigid cystoscope will also result in unnecessary urethral injury and surrounding organ damage.

Summary of the invention

The utility model provides a kind of female ureter bracket extractor aiming at defect of the existing technology, It is easy to operate, without anesthesia and economic cost it is low.

Specific embodiment

As shown in Figure 1-3, the utility model includes push rod 1 and the support sleeve being sheathed on outside push rod 13.

The push rod 1 passes through the support sleeve 3, which is greater than 3 length of support sleeve and push rod 1 can be in support sleeve 3 It is moved forward and backward.

One end of the push rod 1 is a V-type bifurcation structure 6；It is provided between the middle and lower part of the bifurcation structure 6, two bifurcateds of left and right For the V-type elastic slice 5 of gathering, suture 4 is provided between the open end of the bifurcation structure 6, two bifurcateds of left and right；The bifurcation structure 6 Using elastic material, under natural conditions, the bifurcation structure 6 is under the effect of V-type elastic slice 5, open-shaped state.

The other end of the push rod 1 is pierced by 3 end of support sleeve, and the end is fixed with a ring-shaped handle 2, push rod 1 it is another End sequentially passes through the end of support sleeve 3 and ring-shaped handle 2, and silica gel sheath is arranged with outside the support sleeve 3.

Preferably, one end of the V-type elastic slice 5 is connected with the left bifurcated of the bifurcation structure 6, the V-type elastic slice 5 it is another End is connected with the right bifurcated of bifurcation structure 6.

Preferably, the suture 4 is using using PVC elasticity suture 4, one end of the suture 4 with it is described The left bifurcated of bifurcation structure 6 is connected, and the other end of the suture 4 is connected with the right bifurcated of bifurcation structure 6.

Preferably, the silica gel sheath and support sleeve 3 are connected, and the material of the silica gel sheath is medical silica-gel.

Preferably, the bifurcation structure 6 uses micro-elasticity material, and the body of rod 7 of the push rod 1 uses plasticity PVC material, should The body of rod 7 of bifurcation structure 6 and push rod 1 is connected.

Preferably, the push rod 1 can be moved forward and backward in support sleeve 3, pull 1 body of rod 7 of push rod along the direction far from handle 2 One end of handle 2,5 compressive deformation of V-type elastic slice are stretched out, elastic bifurcation structure 6 is retracted in support sleeve 3；(at this point, hand-holdable Handle 2 is by the push rod 1 for being cased with support sleeve 3 to entering in sufferer urethra.) along close to the direction of the handle 2 promotion stretching handle 2 of push rod 1 One end, bifurcation structure 6 stretch out support sleeve 3 outside；V-type elastic slice 5 restores deformation, and bifurcation structure 6 opens；(at this point, rotating push rod 1 So that suture 4 is hung on double J pipe, then pull out push rod 1, double J pipe can be taken out).

Preferably, the sum of the support sleeve 3 and the length of handle 2 are less than the length of 1 body of rod 7 of push rod.

Preferably, the diameter of 1 body of rod 7 of push rod is less than 2 internal diameter of 3 internal diameter of support sleeve and ring-shaped handle.

Preferably, the V-type elastic slice 5 uses elastic material.

The utility model rapidly, easily can entangle the intravesical ureter bracket circle of female patient in art and from urine Road takes out, and without using cystoscope, without using anesthesia, silica gel material and tissue are inviscid, and 6 flexibility of bifurcation structure is good, nothing Wound avoids rigid cystoscope from causing Accessory injury and the pain and discomfort of patient.Meanwhile it is simple and convenient for operation, do not increase patient Pain and infection probability, economic cost is low, noninvasive operation, is easy to be accepted by patients.

The use process of the utility model is illustrated in conjunction with attached drawing and technical solution: holding 3 handle 2 of support sleeve slowly by this reality With in new front per urethra merging sufferer bladder, one end of the stretching handle 2 of push rod 1 is pushed along the direction close to handle 2, before making Bifurcation structure 6 is held to stretch out outside support sleeve 3, V-type elastic slice 5 restores deformation, and bifurcation structure 6 opens, the mobile support sleeve 3 of left and right horizontal Hand 2 detects double J pipe tail end in bladder, and then rotating clockwise support sleeve 3 and push rod 1 makes elastic joint zygonema 4 be hung on double J pipe tail End then pulls out push rod 1 again and recycles bifurcation structure 6, takes out together with double J pipe per urethra, repeats aforesaid operations and takes out another piece of double J Pipe.

It is understood that being merely to illustrate the utility model above with respect to the specific descriptions of the utility model and not being It is limited to technical solution described in the utility model embodiment, those skilled in the art should understand that, it still can be with It modifies to the utility model or equivalent replacement, to reach identical technical effect；Needs are used as long as meeting, all in this reality Within novel protection scope.
