Description
Translated fromChinese技术领域technical field
本发明涉及宫腔镜技术领域，具体为一种妇科宫腔镜手术用气泡排出装置。The invention relates to the technical field of hysteroscopy, in particular to a bubble discharge device for gynecological hysteroscopic surgery.
背景技术Background technique
宫腔镜手术是指用宫腔镜来进行的微创手术。宫腔镜是对子宫腔内疾病进行诊断和治疗的先进设备，它能清晰地观察到了宫腔内的各种改变，明确做出诊断。目前，宫腔镜手术一般采用截石位，过程中需要持续泵入宫腔灌流液，避免在手术过程中气体进入宫腔，造成危害，并且也可以通过不断向宫腔内进水、排水将因为手术时造成的血水以及杂质冲出宫腔，使得置入宫腔内的宫腔镜探头能够更加清晰，方便医生观察宫腔进行手术。Hysteroscopic surgery is a minimally invasive surgery performed with a hysteroscope. Hysteroscopy is an advanced equipment for diagnosing and treating diseases in the uterine cavity. It can clearly observe various changes in the uterine cavity and make a clear diagnosis. At present, hysteroscopic surgery generally adopts the lithotomy position, which requires continuous pumping of uterine perfusate during the process to avoid gas entering the uterine cavity and causing harm during the operation. Because the blood and impurities caused by the operation are flushed out of the uterine cavity, the hysteroscopic probe placed in the uterine cavity can be clearer, and it is convenient for doctors to observe the uterine cavity for surgery.
在向宫腔内注水过程中且未注满时，内部残留的气体会从出水管处排出，当水量到达出水管的最低端口时，水和气体一同排出，此时宫腔内的絮状物杂质容易挂到出水端的管口处，减小管口的截流面积，影响气体的排出效果，随着注水冲洗的时间增加，而且杂质会越聚越多，造成管口堵塞，在后续的电切手术过程中产生的大量气泡无法排出，既影响医生的手术视野，使手术不能顺畅进行，同时大量气泡会通过宫腔开放的血窦进入循环发生空气栓塞，给患者带来致死性的危害。During the process of injecting water into the uterine cavity and it is not full, the residual gas inside will be discharged from the water outlet pipe. When the water volume reaches the lowest port of the water outlet pipe, the water and gas will be discharged together. At this time, the floc in the uterine cavity is Impurities are easy to hang on the nozzle of the water outlet, reducing the interception area of the nozzle and affecting the discharge effect of the gas. As the time of water injection and flushing increases, the impurities will accumulate more and more, causing the nozzle to be blocked. A large number of air bubbles generated during the operation cannot be discharged, which not only affects the doctor's surgical field of vision and makes the operation difficult to perform smoothly, at the same time, a large number of air bubbles will enter the circulation through the open blood sinus of the uterine cavity and cause air embolism, which will bring fatal harm to the patient.
例如申请号为202023075564.1的实用新型专利，一种临床宫腔镜手术灌注系统中的气体过滤置，该过滤装置包括进水管、排气管、出水管、过滤瓶、阻气夹和塞子，过滤瓶内装有过滤液，过滤瓶上盖有塞子，塞子上开有三个孔，分别插有进水管、排气管和出水管，进水管和排气管位于过滤液的液面上方，出水管位于过滤液的液面下。虽然该专利可以避免进水管内气体进入人体宫腔，但是在手术过程中，宫腔内部也会产生气体和杂质，在排水管堵塞的情况下气体无法排出，该装置无法解决。For example, the utility model patent with the application number of 202023075564.1, a gas filter device in a clinical hysteroscopic surgical perfusion system, the filter device includes a water inlet pipe, an exhaust pipe, a water outlet pipe, a filter bottle, an air blocking clip and a stopper, and the filter bottle There is filtrate inside, the filter bottle is covered with a stopper, and there are three holes on the stopper, which are respectively inserted with a water inlet pipe, an exhaust pipe and a water outlet pipe. below the liquid level. Although the patent can prevent the gas in the water inlet pipe from entering the human uterine cavity, during the operation, gas and impurities will also be generated inside the uterine cavity. When the drainage pipe is blocked, the gas cannot be discharged, and the device cannot solve the problem.

1、该妇科宫腔镜手术用气泡排出装置，通过壳体与膜板、转杆与锥台的配合设置，水流充斥到壳体内时，在水流的作用下推动膜板转动，膜板带动转球转动，通过锥台和转杆的配合设置，锥台可以转动，通过棘轮和棘爪的配合设置，锥台只能单方向转动，设置膜板，减小膜板与水流的接触面积和摩擦力，水流中杂物不会挂到膜板上，避免了堵塞。1. The air bubble discharge device for gynecological hysteroscopic surgery is set by the cooperation between the shell and the diaphragm, the rotating rod and the cone frustum. When the water flow fills the shell, the diaphragm is driven to rotate under the action of the water flow, and the diaphragm drives the rotation. When the ball rotates, the truncated cone can be rotated through the cooperation of the truncated cone and the rotating rod. The truncated cone can only be rotated in one direction through the cooperation of the ratchet and the pawl. The diaphragm is set to reduce the contact area and friction between the diaphragm and the water flow. force, the debris in the water flow will not hang on the membrane plate, avoiding clogging.
2、该妇科宫腔镜手术用气泡排出装置，设置活塞柱，在壳体中水流减小的情况下，膜板带动锥台转动变缓，从而降低了滑块受到第四齿轮的离心力，继而打破活塞柱的受力平衡，在拉簧的作用下拉动活塞柱横向移动，抽动挂在排水管管口处堆积的杂质，对管口进行清理。2. The bubble discharge device for gynecological hysteroscopic surgery is equipped with a piston column. When the water flow in the casing is reduced, the diaphragm plate drives the cone to rotate slowly, thereby reducing the centrifugal force of the fourth gear on the slider. Break the force balance of the piston rod, pull the piston rod to move laterally under the action of the tension spring, twitch the accumulated impurities hanging on the nozzle of the drain pipe, and clean the nozzle.

在使用时，在使用该妇科宫腔镜手术用气泡排出装置时，首先将该装置放到病人宫腔内部，然后通过进水管4将水注入到宫腔中，此时宫腔内的气体从排水管2端口处进入，然后经过排水支管6排出，在水流经过排水支管6并通过进水口10进入到壳体23中时，水流推动膜板21转动，膜板21带动转球22转动，转球22带动转杆20转动，转杆20在自转的同时，带动锥台19进行转动，锥台19通过主动轴17带动第一齿轮12转动，第一齿轮12通过第三齿轮16带动转轴15转动，然后转轴15通过第二锥齿轮42带动第一锥齿轮41转动，第一锥齿轮41带动通过传动块32带动第五齿轮33转动，接着第五齿轮33通过活塞柱9表面的齿槽时活塞柱9拉动拉簧8缓慢拉伸，同时齿槽带动拨板31顺时针拨动，当第五齿轮33与齿槽脱离后，活塞柱9通过拉簧8的拉力带动拨板31逆时针转动，接着拨板31的另一端与翘板29抵接，阻挡拨板31的转动，对活塞柱9的位置进行固定。When in use, when using the air bubble discharge device for gynecological hysteroscopic surgery, the device is first placed inside the patient's uterine cavity, and then water is injected into the uterine cavity through the
在转轴15转动的同时，第二齿轮14对第四齿轮25进行加速转动，使第四齿轮25获得较大的离心力，滑块26在离心力的作用下沿着滑槽向第四齿轮25的边缘移动，并挤压第三压簧40带动压环28向上移动。When the
当水量刚接触到排水管2时，宫腔内的絮状物会挂到排水管2管口的边缘，随着时间的增加，水流不断对宫腔进行冲洗和手术不断的进行，管口的絮状物会越聚越多，减小排水管2的通水量，膜板21的转速减小，此时第四齿轮25的离心力会降低，压环28在第三压簧40的作用下向下移动，压动翘板29的一端向下移动，此时翘板29的另一端翘起，与拨板31脱离，活塞柱9在拉簧8的作用下快速向支撑板1接近，此时扇形板45在吸力的作用下与定位板47闭合，阻挡排水支管6中液体的回流，同时对排水管2端口处挂着堵塞的杂质进行疏通，如果扇形板45表面同样有絮状漂浮物，通过与定位板47的闭合，切刀44对其进形切断。When the amount of water just touches the
在压环28压动翘板29移动的同时，翘板29的另一端会带动推板35移动，推板35带动挡板38在限位壳37中滑动，挡板38与传动轴36脱离，传动轴36在第二压簧39的作用下推动传动块32带动传动轴36移动，此时第一锥齿轮41与第二锥齿轮42脱离，接着活塞柱9向支撑板1接近。When the
综上，该妇科宫腔镜手术用气泡排出装置，通过壳体23与膜板21、转杆20与锥台19的配合设置，水流充斥到壳体23内时，在水流的作用下推动膜板21转动，膜板21带动转球22转动，通过锥台19和转杆20的配合设置，锥台19可以转动，通过棘轮11和棘爪18的配合设置，锥台19只能单方向转动，设置膜板21，减小膜板21与水流的接触面积和摩擦力，水流中杂物不会挂到膜板21上，避免了堵塞，设置活塞柱9，在壳体23中水流减小的情况下，膜板21带动锥台19转动变缓，从而降低了滑块26受到第四齿轮25的离心力，继而打破活塞柱9的受力平衡，在拉簧8的作用下拉动活塞柱9横向移动，抽动挂在排水管2管口处堆积的杂质，对管口进行清理。To sum up, the air bubble discharge device for gynecological hysteroscopic surgery is arranged through the cooperation between the
