Balloon type uterus raising deviceTechnical field
The present invention relates to technical field of medical instruments, more particularly, to a kind of balloon type uterus raising device.
Background technology
As laparoscopic technique is in the popularization and application of Gynecology, at present almost all of Gynecological acute abdomwn is all by abdomenEndoscope-assistant surgery is substituted.And laparoscopic surgery possess abdominal it is unsurpassable it is minimally invasive, get a clear view, recover fast, go outThe advantages of insufficiency of blood.Most gynecological laparoscopic operations all be unable to do without an important operating theater instruments --- uterus raising device.Uterus raising deviceInitial design be for manipulating uterus producing appropriate tension force, appearing operative space or convenient some special portions for reaching pelvic cavityPosition, its application provides important guarantee for the exposure of female pelvic cavity surgical field of view.Uterus raising device is used for the lower Jing of peritoneoscope auxiliaryVaginal hysterectomy and total hysterectomy under laparoscopy, the logical fluid inspection of fallopian tube dyeing under peritoneoscope, and various abdomensCoordinate positioning uterus during endoscope-assistant surgery.At present uterus raising device is widely used in gynecological's total hysterectomy inside fascia operation, due to pelvic cavity and the external worldCommunicate, substantial amounts of swollen abdomen gas and interior liquid can overflow from uterine cavity after hysterectomy.
In order to prevent intrauterine gas and interior hydrorrhea from going out and preferably expose surgical field of view, just derive except with sacculusUterus raising device, existing balloon type uterus raising device has two air bags mostly, and one is arranged on the front end of pendulum palace bar again after its expansion,On the one hand uterus is lifted, on the other hand pendulum palace bar and uterus is carried out position and fixed, it is to avoid pendulum palace bar is to endometriumDamage；Another air bag is arranged on the rear end of pendulum palace bar, is expanded after expansion, and vaginal walls of fitting, and prevents from performing the operationIntraabdominal gas and interior liquid in journey flows out, and advantageously ensures that surgical field of view after expanding.On the one hand, existing balloon type is liftedThe air bag of the rear end of palace device is fixed with uterus raising device mostly, and due to age etc., the size of factor cavity of uterus is also different, and utricule is certainDepth is difficult to perfect laminating vaginal walls, be to uterus raising device anterior displacement so that utricule keeps complete laminating to maintain pneumoperitoneum, veryEasily make pendulum palace bar bore a hole uterus, affect operation safety, and maintain pneumoperitoneum effect poor；On the other hand, put palace bar to adjustSection is difficult, it is difficult to provides optimal operation angle, exposure surgical field of view, affects procedure efficiency and postoperative effect.
In order to solve the problems, such as prior art, people have carried out long-term exploration, it is proposed that solution miscellaneousScheme.For example, Chinese patent literature discloses a kind of folding type versatile uterus lifting machine [application number：200920171562.7], byPendulum palace bar, in utero sacculus, the injection mouth of pipe, cervix uteri support, vagina blocking capsule, support rod, rotary handle, positioning knob are with synchromesh gearToothed Belts Gearing is connected and composed.The annular tooth clutch of positioning knob joystick, handle is rotated and drives synchronous toothed belt gear and Bai GongBar, the upper and lower swing of cervix uteri support or stop；Swung with swing control pendulum palace bar, cervix uteri support of handle.
Such scheme solves the problems, such as to a certain extent existing uterus raising device, but remains：Pendulum palace barAdjust inconvenience, it is difficult to uterus is lifted well, there is provided optimal surgery location；In total hysterectomy, it is difficult to by adjustingThe position of section positioning utricule maintains the technical problems such as pneumoperitoneum effect difference reaching optimal seal state.
The content of the invention
The purpose of the present invention is for the problems referred to above, there is provided a kind of simple structure, simple operation, can effectively maintain pneumoperitoneumBalloon type uterus raising device.
To reach above-mentioned purpose, following technical proposal is present invention employs：This balloon type uterus raising device, including bar shaped support,Pendulum palace bar is hinged with the front end of bar shaped support, described puts palace bar and can control to put what palace bar swung relative to bar shaped supportSwing driving mechanism is connected, it is characterised in that described pendulum palace bar periphery is arranged with the act palace cup that can be swung with pendulum palace bar, andThe front end of pendulum palace bar is exposed to act palace cup, and described bar shaped support is provided with positioning utricule and positions utricule and conveys with first mediumMechanism is connected, and being provided between described positioning utricule and bar shaped support can be along the axially adjustable positioning utricule position of bar shaped support and energyPositioning utricule is positioned at into the adjustable positioning mechanism of bar shaped support.
