Description

A kind of vagina guide
Technical field
This utility model relates to technical field of medical instruments, specifically, is a kind of vagina guide.
Background technology
Laparoscopic surgery is an invasive methods that new development is got up, and is an inexorable trend of following operation method development.Along with advancing by leaps and bounds of industrial manufacturing technology, new technique is carried out in being fused to of related discipline, new method has been established firm basis, add the operation that doctor is more and more consummate, the open operation in many past is replaced by laparoscopic surgery now, significantly increased the chance of Minimally Invasive Surgery.
Traditional uterectomy is the operation of abdomen formula, and along with the development of gynecological's Minimally Invasive Surgery technology, laparoscopic surgery replaced traditional abdominal gradually in recent years.In hysterectomy, mainly contain that uterus time is cut, total hysterectomy inside fascia and Radical Hysterectomy and pelvic lymphadenectomy.
In operation process, need to expose corresponding operative site, and avoid important internal organs around, as ureter, bladder, rectum etc., to avoid damage, this all be unable to do without the auxiliary of uterus raising device.The most frequently used uterus raising device structure of hysterectomy transvaginal used under existing peritoneoscope is more complicated, and abecedarian be difficult for to grasp, and easily passes uterus and causes damage; Can only move all around in addition, cannot accomplish to rotate to the left or to the right; Also have after hysterectomy, because the opening of Vaginal Stump is leaked gas, so Vaginal Stump is sewed up, can only carry out by transvaginal, to operation technique, make troubles.For example, the cup-shaped formula uterus raising device using in total hysterectomy inside fascia operation at present, be to use a rigid cup-shaped device fill in intravaginal and entangle cervix uteri and lift palace from vaginal orifice, guide rod inserts cervix uteri mouth and also enters cavity of uterus, and makes its rim of a cup entangle cervical orifice to lift palace.In actual operation process, operation is more difficult to abecedarian, often cannot be guide rod intron cervix uteri fixing in cup-shaped device, make to lift palace effect not in place; Or undue force passes uterus by guide rod, cause damage.When extensive panhysterectomy and pelvic lymphadenectomy, higher to the requirement of uterus raising device.
In sum, need a kind of easy to operate, safe and reliable, operating theater instruments that still can keep pneumoperitoneum state after hysterectomy badly, but about this class apparatus, have not been reported at present.
Summary of the invention
The purpose of this utility model is that a kind of vagina guide is provided.
For achieving the above object, the technical scheme that this utility model is taked is:
A vagina guide, comprises uterus guide, conduit and handle; Described uterus guide is provided with guide rod and is connected in the support arm of the bifurcated of guide rod head end; Described guide rod is socketed on the inside of conduit, and described support arm stretches out in outside catheter head, and described guide rod tail end stretches out in outside tail end of conduit and connects handle; Described guide rod respectively with conduit and handle threaded engagement.
Preferably, described support arm has two, between two support arms and guide rod, all has inclination angle.
Preferably, described support arm head is blunt round.
Preferably, described catheter head is tapered, and is important actor shape.
Preferably, described vagina guide is also provided with vagina sealed tube, and described vagina sealed tube tail end is provided with the seal cover with through hole and flap valve, and described sheathed catheter is connected to the inside of vagina sealed tube, and tail end passes in flap valve and through hole, stretch out in the outside of seal cover.
Preferably, described micro-the sticking up of vagina sealed tube head, with the inclination angle of vagina sealed tube main body be 1-10 degree.Preferred, the upper limb of described vagina sealed tube head is slightly short than lower edge.
Preferably, the edge of described vagina sealed tube head thickens.
This utility model advantage is:
1, uterus guide is established forked two support arms, guide rod tail end and conduit, handle screw thread are tightened, thereby making patient can realize uterus by operating handle moves to front, rear, left and right, also can rotate a certain angle to the left or to the right, lift palace more light, operate also more flexible;
2, conduit head end is important actor shape, is convenient to insert cervix uteri internal orifice, can strengthen fixation;
3, support arm head is blunt round, and behind insertion uterus, double end stretches into angle, palace, both sides naturally, be difficult for horizontally slipping, and stress point dispersion, local pressure reduces, and is difficult for penetrating uterus and causes damage, and safety coefficient is high;
4, be provided with vagina sealed tube, and be combined with the seal cover with flap valve, guarantee still can maintain pneumoperitoneum state after hysterectomy, be convenient to sew up Vaginal Stump under peritoneoscope, or after hysterectomy, continue at the descending pelvic cavity lymphadenectomy of peritoneoscope, while vagina sealed tube can serve as gets sundries, and the lymph transvaginal scaling off is taken out external, difficult omission, can save again and get thing bag;
5, the shape of vagina sealed tube head design Cheng Weiqiao, and upper limb is short compared with lower edge, can guarantee that it meets the naturalness of vagina;
6, the edge of vagina sealed tube head is slightly thick, and after insertion vagina, this place is slightly protruding, is convenient to the position of operator identification TURP while cutting uterus.
In a word, vagina guide of the present utility model is practical, safety, and no matter full uterus or extensively full uterus can be general, and particularly extensively panhysterectomy, more has incomparable advantage.
