Description

A fluid collection device for hysteroscopic surgery

technical field

The utility model relates to the technical field of hysteroscopic electric resection, in particular to a liquid collecting device for hysteroscopic surgery.

Background technique

Hysteroscopic resection is a newly developed minimally invasive surgery in the field of gynecology in recent years. It has the advantages of short operation time, less trauma and less bleeding. It gradually replaces hysterectomy or laparotomy. , welcomed by the majority of doctors and patients. Hysteroscopic surgery needs to use dilatation equipment and perfusate to expand the uterine cavity, which is convenient for the surgeon to observe the operative field and operation. While forming a visual space, the perfusate may also be excessively absorbed by the body in a short period of time, causing the body fluid to exceed the limit. Load and (or) dilution hyponatremia (TURP syndrome), electrolyte balance disorders, heart failure, pulmonary edema and cerebral edema, and even death. Its incidence rate is 0.17% in China and 0.2% in foreign countries. Early diagnosis is the key to cure. Therefore, how to prevent the leakage of perfusate during hysteroscopic surgery, effectively collect and measure the perfusate flowing out of the uterine cavity, to calculate the amount of perfusion fluid, has positive significance for the prevention of TURP syndrome.

At present, the hospital uses one-piece single-use disposable hole towel combined with vaginal brain surgery film in urological and gynecological hysteroscopic surgery, but the tail of the film towel is open, and we put the tail in a bucket during the operation. It is used to collect the fluid flowing out of the uterine cavity. The amount cannot be accurately estimated during the operation. If the operation time is long, the liquid in the collection bucket is full and needs to be replaced during the operation, which will affect the operation of the surgeon and even prolong the operation time. Increasing the workload of nurses in the operating room brings great inconvenience and is ineffective. Because the last hole towel is not completely aligned with the patient's skin, the liquid will flow into the patient's body through the hole of the film towel during the operation, so that the perfusate leaked during the operation often soaks the sterile cotton sheet and contains some liquid. It will leak the floor of the operating room. If the foot pedal placed on the floor is soaked, electrical conductivity will also occur, which will also affect the accurate calculation of the absorption of perfusate, so that TURP syndrome cannot be detected in time, which is not conducive to early prevention and treatment. If the uterine cavity or prostate tissue falls into the film bag during the operation, the surgeon will also search for the surgical specimen in the barrel after the operation, which brings great inconvenience to the operation. At present, the measuring bucket is placed in front of the surgeon to facilitate the collection of liquid, but the height and width of the bucket directly affect the operation of the surgeon, and during hysteroscopy and urological operations, the operating room nurses are busy before the operation begins. Connecting instruments and equipment, placing measuring buckets, and hanging irrigation fluid, sometimes it is inevitable to miss work details. During the operation, pay attention to the irrigation fluid, avoid the liquid from emptying, and pay attention to the output. The workload is very huge. Therefore, how to use an efficient and simple method to collect intraoperative fluid output and collect surgical specimens is the focus of current clinical attention.

In order to solve the above problems, workers in the field have conducted different studies on a collection device for hysteroscopic surgery:

Chinese Patent Publication No. CN212547014U discloses a hysteroscopic dilatation fluid collection device. A hysteroscopic uterine distention fluid collection device comprises a surgical film that can be pasted for medical use, a hole for the uterine distention fluid to pass through is arranged in the middle of the operating film, and a storage bag is arranged below the hole, wherein an anti-blocking device is connected to the bottom of the storage bag Pipe, the outlet end of the anti-blocking pipe is communicated with a confluence cavity, and the confluence cavity is communicated with a collection bag for collecting dilatation fluid through the connecting pipe, and the anti-blocking pipe comprises a first branch pipe and a second branch pipe, the first branch pipe and the second branch pipe The water inlet ends of the branch pipes are respectively connected with the water outlet ends of the bottom of the storage bag, the water outlet ends of the first branch pipe and the second branch pipe are connected and both are connected with the water inlet end of the confluence cavity, the storage bag, the first branch pipe, the second branch pipe, the confluence cavity It forms an anti-clogging collection channel with the functions of storage, shunt filtration and confluence with the filter screen. The utility model is a hysteroscope dilatation fluid collection device, which is convenient to use and can effectively reduce the probability of pipeline blockage. However, in this patent application, the position where the collection bag is placed must be lower than the position where the storage bag is placed, so that the dilatation fluid can flow into the collection bag, and it is not easy to observe the scale on the collection bag at this time, requiring staff Bend down to get closer to see clearly.

Therefore, it is necessary to further improve a liquid collecting device for hysteroscopic surgery to solve the above-mentioned various misconduct.
