An embodiment of the present invention provides a hysteroscope operation monitoring system, and specifically, referring to fig. 1, fig. 1 shows a structural block diagram of a hysteroscope operation monitoring system in one embodiment of the present invention, which includes a uterus swelling liquid bag 1, a waste liquid collecting bottle 2, a two-wheel uterus swelling pump, a liquid inlet monitoring device, a liquid outlet monitoring device and an intelligent terminal.

The uterus expanding liquid bag 1 is used for a liquid medium for expanding the uterus in hysteroscopy operation, and the commonly used uterus expanding liquid medium comprises normal saline, mannitol solution and the like. The waste liquid collecting bottle 2 is used for collecting uterine distention medium flowing out of the uterine cavity, and it should be noted that in the operation, three paths of the uterine distention liquid medium flowing out of the uterine cavity are provided, wherein one path is flowing out of the body through a backflow channel of the hysteroscope, and is a main flowing path of the uterine distention liquid medium; secondly, the liquid flows out of the body from the gap between the hysteroscope and the cervical canal; thirdly, the medicine enters the abdominal cavity through the oviduct for absorption, or enters the blood vessel through the surgical wound (when the blood sinus is opened, the arteriole is cut off and the like) for absorption, and the liquid volume flowing out is the loss volume. The amount of the fluid loss is also called as the amount of deficiency or difference, the value reflects the capacity of a human body to absorb the uterine distention liquid medium, and the excessive absorption of the uterine distention liquid medium is easy to cause great risk of postoperative or postoperative complications such as water poisoning and the like. Correspondingly, the inflow in the embodiment of the invention refers to the volume of the uterine distention liquid medium entering the uterine cavity through the double-wheel uterine distention pump, and is also called the inflow, and the outflow refers to the volume of the uterine distention liquid medium flowing out of the uterine cavity, including the volume flowing out through the outflow channel of the hysteroscope and the gap between the hysteroscope and the cervix, and is also called the outflow.

Specifically, referring to fig. 2, fig. 2 is a schematic structural diagram of a two-wheel uterine distention pump in an embodiment of the invention (some components are not shown in the drawing, for example, the pressure sensor 5 and the first liquid flow sensor 6 are spatially located at the same position, and only the pressure sensor 5 is shown in fig. 2), which includes a peristaltic wheel for driving a uterine distention liquid medium into a uterine cavity through a perfusion pipeline and a perfusion channel of a hysteroscope, which is called a perfusion wheel 3 for short; and a peristaltic wheel which drives the uterus expanding liquid medium flowing out of the uterine cavity in the operation to enter a waste liquid collecting bottle through a waste liquid pipeline, and is called a collecting wheel 4 for short.

Certainly, the liquid uterus expanding medium needs to flow through a corresponding pipeline, in this embodiment, a liquid inlet pipeline is arranged on the perfusion wheel 3, the liquid inlet pipeline is connected with the uterus expanding liquid bag 1, and the perfusion wheel 3 is used for driving the uterus expanding medium in the uterus expanding liquid bag 1 to enter the uterine cavity through the liquid inlet pipeline; the collecting wheel 4 is provided with a liquid outlet pipeline, the liquid outlet pipeline is connected with the waste liquid collecting bottle 2, and the collecting wheel 4 is used for driving a womb swelling medium flowing out of a uterine cavity to enter the waste liquid collecting bottle 2 through the liquid outlet pipeline.

The inlet monitoring device in this embodiment is including locating pressure sensor 5 and first liquid flow sensor 6 on the inlet line, go out liquid monitoring device is including locating second liquid flow sensor 7 on the play liquid pipeline. The first liquid flow sensor 6 and the second liquid flow sensor 7 are used for monitoring the inflow and outflow to obtain corresponding flow data, and the pressure sensor 5 is used for detecting the perfusion pressure and is generally arranged at the outlet of the pump tube of the perfusion wheel 3 of the double-wheel uterus swelling pump.

The intelligent terminal in this embodiment is used for acquiring flow data of the liquid inlet monitoring device and the liquid outlet monitoring device, performing data processing, and feeding back corresponding control signals to the double-wheel uterus swelling pump 5, so as to ensure that safe perfusion pressure and uterus swelling liquid medium amount meeting the surgical requirements are maintained.

As described in the background of the invention, it is important to take safe and effective measures in hysteroscopic surgery to reduce the risk of complications caused by excessive absorption of distending liquid media. Especially for operations with high risk and expected to require longer operation time or operations involving muscle layer excision, a set of operation schemes for avoiding excessive absorption of liquid should be established before the operation, including using hormone or diuretic, selecting isotonic womb swelling liquid medium, selecting operation instruments with higher operation efficiency or safety, strictly controlling operation time, performing staged operation, etc. The uterus expanding liquid medium must be accurately and strictly monitored and managed in the operation of an operation team, and the uterus expanding liquid medium must be accurately monitored and managed in the whole process by using a uterus expanding pump with an advanced function as much as possible.

At present, most of liquid medium uterine expansion pumps used in hysteroscopy operations in the prior art are single-peristaltic-drive uterine expansion pumps (hereinafter referred to as single-wheel uterine expansion pumps), and the peristaltic wheel of a commonly-used single-wheel uterine expansion pump is a one-way perfusion wheel (a small number of uterine expansion pump perfusion wheels have a reverse suction function, the same applies below), and is responsible for driving liquid media into a uterine cavity uterine expansion chamber through a perfusion pipeline and a hysteroscopy perfusion channel, so that a corresponding operation space is provided for the hysteroscopy operations.

The single-wheel uterus expanding pump is mainly divided into two functional types of products, one is provided with the functions of filling and monitoring the filling pressure, and the other is connected with a liquid medium input and output weighing and measuring functional unit on the basis of the functions of filling and monitoring the filling pressure. The single-wheel uterine expansion pump with the functions of filling and monitoring the filling pressure is the most common, and the uterine expansion liquid medium pumped out by the filling wheel of the single-wheel uterine expansion pump flows through the pressure measuring module at the outlet of the pipeline of the filling wheel, the pressure measuring module monitors and controls the filling pressure of the perfusion pipeline (namely the filling pressure), but the single-wheel uterine expansion pump does not have the functions of monitoring the outflow, the loss and the like of the uterine expansion liquid medium in real time and controlling the system. During or after the operation, the inflow and the estimated outflow are subtracted manually to obtain the outflow with a certain error. The real-time and accurate process monitoring of the capacity of the human body for absorbing the uterine distention liquid medium in the operation can not be carried out, so that the risk of complications caused by excessive absorption of the uterine distention liquid medium is higher.

On the basis of having the functions of filling and monitoring the filling pressure, the single-wheel uterus swelling pump externally connected with a liquid medium input and output weighing and measuring functional unit only finds that a few foreign manufacturers develop the technology at present, but the practicability is limited. The problems mainly lie in that: 1. the assembly is complex, and the operation is complex; 2. the working state of the weighing and measuring unit is easily interfered by external factors, such as vibration, movement, collision, salt water bag replacement, waste liquid bottle replacement and the like, and large data errors are likely to occur. To avoid excessive errors, the uterus expansion pump or the weighing and measuring unit may even be forced to pause; 3. measurement data under different endoscopic surgical conditions lack clinical reference or instructional value; 4. the occupied space of the field is large; 5. the weighing unit and the special trolley need to be purchased additionally; 6. the weighing unit only has the function of alarming the abnormal loss, the perfusion pressure and the flow of the uterine cavity pump need to be adjusted manually, the real-time controllability is not high, and the attention of an operator is also easily interfered.

The hysteroscope operation monitoring system provided by the embodiment of the invention integrates all independent functional units for monitoring and controlling the input and output amount into a whole to form a liquid monitoring and management system taking microcomputer control system technology as a core, accurately and timely monitors and analyzes the perfusion pressure, the flow rate, the inflow amount, the outflow amount and the loss amount of the uterine distention liquid medium, automatically and timely implements process control such as warning, adjustment and the like, and ensures that the safe perfusion pressure and the uterine distention liquid medium amount which meet the operation requirements are maintained. Aiming at different hysteroscopic operations, the working parameters of the liquid medium in a special mode can be selected. In addition, when special requirements are required by special cases, the operating doctor or the instrument nurse can adjust the working parameters of the system correspondingly.

Further, in the embodiment of the present invention, the intelligent terminal includes a processor 8, a human-computer interaction interface 9, an alarm module 10, and an auxiliary control module 11; the signal communication end of the processor 8 is respectively connected with the liquid inlet monitoring device, the liquid outlet monitoring device, the human-computer interaction interface 9 and the alarm module 10; the control end of the processor 8 is respectively connected with the double-wheel uterus swelling pump and the auxiliary control module 11.

Further, in the above embodiment, the hysteroscope operation monitoring system further comprises a hip-bottom collection sheet 12; the hip bottom collection sheet 12 is used for collecting uterine swelling medium flowing out of the uterine cavity, and a liquid outlet of the hip bottom collection sheet is connected with the liquid outlet pipeline.

Specifically, referring to fig. 3, fig. 3 is a schematic flow diagram of a uterine distention liquid medium in one embodiment of the present invention, wherein the uterine distention medium is driven by the perfusion wheel 3, flows to the uterine cavity under the monitoring of the pressure sensor 5, is then discharged from the body, is collected by the hip bottom collection unit 12, and flows to the waste liquid collection bottle 2 under the driving of the collection wheel 4. The uterus expanding liquid medium is driven by the perfusion wheel 3 to be conveyed to the outlet of the pump pipe for perfusion pressure measurement, the hysteroscope operation monitoring system continuously monitors the perfusion pressure by taking the set perfusion pressure as the upper limit, simultaneously measures the inflow of the uterus expanding liquid medium, and the tail end of the perfusion pipeline is connected to a perfusion channel of the hysteroscope to enter the uterine cavity. The uterus expanding liquid medium flowing out of the uterine cavity is collected by a hip bottom collection sheet 12 and then is driven by a collection wheel 4 to be conveyed to a waste liquid collection bottle 2, the outflow of the uterus expanding liquid medium is continuously measured by a hysteroscope operation monitoring system, and the loss is calculated according to the inflow and the outflow measured in real time.

In the operation process, if the real-time perfusion pressure reaches the upper limit of the preset safety value, the hysteroscope operation monitoring system can warn in time, reduce the speed and reduce the volume and stop perfusion when necessary. And when the perfusion pressure is reduced to be within the upper limit of the safety value, the peristaltic wheel automatically restarts perfusion. If the patient is in a special condition, the operation team can reset the relevant parameters according to the actual condition, and the details are not repeated herein.

The hysteroscope operation monitoring system monitors the change of the loss in real time, and if the real-time loss reaches the upper limit of the preset safety value, the hysteroscope operation monitoring system gives an audible and visual alarm in time and stops the perfusion. The operation team can also set an early warning value for 1 time or multiple times within the upper limit of the safety value according to the actual situation, and the sound-light alarm is used for reminding the operating doctor to pay attention to the operation and timely dispose the operation so as to ensure that the operation is safely, leisurely and efficiently carried out.

For the human-computer interaction interface 9 on the intelligent terminal, preferably, data such as real-time perfusion pressure, flow, outflow, loss and the like are simultaneously displayed on the human-computer interaction interface 9 of the double-wheel uterus dilating pump, so that medical staff can conveniently watch and refer in time.

The principle of the hysteroscopic operation monitoring system of the present invention will be described in detail below by taking the bipolar plasma hysteroscopic resectioning operation of the submucosal myoma of uterus as an example.

Firstly, the patient puts the hip-bottom collection sheet 12 on the sleeve, and positions the patient to complete anesthesia. Preparing a bipolar plasma electric cutting hysteroscope instrument on the platform, connecting a camera system and a bipolar plasma controller under the platform, and starting up to complete self-checking; then, the height of the double-wheel uterine expansion pump is adjusted, and the horizontal height of the double-wheel uterine expansion pump is kept approximately close to the horizontal height of the uterine cavity of the patient; then, installing a sterilized double-wheel uterus expanding pump liquid pipeline, in this embodiment, the liquid pipeline includes a liquid inlet pipeline and a liquid outlet pipeline, specifically, please refer to fig. 4 and 5, fig. 4 shows a schematic structural diagram of the liquid inlet pipeline in one embodiment of the present invention, fig. 5 shows a schematic structural diagram of the liquid outlet pipeline in one embodiment of the present invention, the liquid inlet pipeline includes a first liquid inlet pipeline section 13, a perfusion wheel pump pipeline section 14 and a first liquid feeding pipeline section 15, one end of the first liquid inlet pipeline section 13 is connected to the uterus expanding liquid bag 1, the other end of the first liquid inlet pipeline section 13 is connected to one end of the perfusion wheel pump pipeline section 14, the perfusion wheel pump pipeline section 14 is disposed on the perfusion wheel 3, the other end of the perfusion wheel pump pipeline section is connected to one end of the first liquid feeding pipeline section 15, and the other end of the first liquid feeding pipeline section 15 is connected to a water inlet valve of the hysteroscope, so that uterus expanding medium enters the uterine cavity.

Go out the liquid pipeline and include that second feed liquor pipeline section 16, collection wheel pump pipeline section 17 and second send liquid pipeline section 18, the one end of second feed liquor pipeline section 16 with single 12 connections are collected at the bottom of buttockss, the other end of second feed liquor pipeline section 16 with the one end of collection wheel pump pipeline section 17 is connected, collection wheel pump pipeline section 17 is located collect on the wheel 4, its other end with the second send the one end of liquid pipeline section 18 to be connected, the second send the other end of liquid pipeline section 18 with waste liquid receiving flask 2 connects.

Then, the double round uterus expansion pump is started to complete self-checking, an electrotomy operation mode in the hysteroscope mode is selected, the uterus expansion liquid medium type (normal saline) is selected, the system automatically sets the safety upper limit of the working parameters such as the perfusion pressure (such as 100 mmHg) and the loss (such as 2000 ml), and if the patient condition is special (such as the uterus expansion effect in the operation is not good), the operation doctor can also reset the relevant parameters according to the actual condition. After the gas in the perfusion pipeline and the hysteroscope is exhausted, the hysteroscope is put in to complete the perfusion and the uterus expansion, and then the myoma electrostomy operation can be carried out.

In the operation process, the perfusion wheel 3 of the double-wheel uterus expansion pump continuously conveys the physiological saline to the uterus cavity for expanding the uterus cavity through the liquid inlet pipeline and the perfusion channel of the hysteroscope. When filling wheel 3 and rotating extrusion pump line and carry normal saline, pressure sensor 5 lasts and monitors the liquid pressure of feed liquor pipeline promptly and fills the pressure to reach intelligent terminal with the real-time transmission of monitoring data. In addition, the intelligent terminal can calculate the inflow through the rotating speed of the perfusion wheel 3, and the inflow can also be obtained through the arrangement of the first liquid flow sensor 6. If the water inlet valve of the hysteroscope liquid inlet pipeline is closed or the hysteroscope liquid outlet pipeline is blocked, the system can automatically detect that the filling pressure is changed, and if the filling pressure exceeds the set upper limit of the filling pressure, the system automatically sends out a warning and adjusts the filling flow, and stops filling when necessary. Below the set upper limit, the system re-drives the pump.

In the embodiment, the collecting wheel 4 is continuously driven by the double-wheel uterus expanding pump while the filling wheel 3 drives the pump to fill, so that the normal saline which flows out of the body through the hysteroscope backflow channel and the gap between the hysteroscope and the cervical canal and is collected in the buttock bottom collecting unit 12 is sucked to the waste liquid collecting bottle. When the physiological saline sucked by the hip bottom collection sheet 12 flows in the collection pipeline, the physiological saline is continuously monitored by the second liquid flow sensor 7 of the pump pipe section 17 of the collection wheel, and the measured data is the real-time outflow.

The intelligent terminal subtracts the real-time inflow from the outflow to obtain the real-time loss, and the real-time loss is displayed on the human-computer interaction interface 9 of the double-wheel uterine distention pump in real time. If the loss reaches the set upper limit (such as 2000 ml), the system gives out sound and light alarm through the alarm module 10, and the water pumping is automatically stopped. After the operating doctor takes corresponding measures, if the operation can be continued, the operating key is pressed to confirm, the system is restarted, and the relevant working parameters are continuously monitored until the operation is finished.

Of course, in the bipolar plasma hysteroscope resectioning operation process for the submucosal myoma of uterus of this embodiment, if other surgical instruments such as a plasma electrode need to be replaced, the water inlet valve of the hysteroscope can be directly closed. After the instrument is replaced, the water inlet valve is opened, the double-wheel uterine expansion pump is started, and after the pipeline and the inner channel of the endoscope are emptied, the endoscope is re-inserted for continuing the operation. Similarly, if the liquid pipeline needs to be replaced, the pause key on the intelligent terminal needs to be pressed down first, and the operation can be continued by canceling the pause instruction after the replacement is finished.

After the operation is finished, withdrawing the hysteroscope, closing the water inlet valve, pressing the pause key, closing the pipe clamp of the liquid inlet pipeline, pulling out the liquid inlet pipeline from the outlet pipe of the saline bag, emptying the normal saline of the liquid inlet pipeline, and completely sucking the normal saline in the collection unit 12 at the bottom of the buttocks. The liquid inlet pipeline can be repeatedly used, and the liquid outlet pipeline is disposable. Certainly, the intelligent terminal in this embodiment can store data, and after the operation is finished, the operating doctor can enter the human-computer interaction interface 9 of the intelligent terminal of the hysteroscope operation monitoring system, and copy out the relevant data stored in real time for analysis and research.

Specifically, referring to fig. 6, fig. 6 shows a schematic flow chart of a hysteroscopic operation monitoring method provided in one embodiment of the present invention, which is applied to the above-mentioned hysteroscopic operation monitoring system, and the method specifically includes steps S1 to S4:

s1, starting the double-wheel uterus expanding pump and carrying out self-checking;

s2, determining various parameters required by the hysteroscope operation;

s3, calculating the loss of the uterine distention medium in real time according to data results obtained by the first liquid flow sensor and the second liquid flow sensor in the operation process;

and S4, if the loss is higher than a preset safety threshold, correspondingly controlling the working states of the double-wheel uterus swelling pump and the intelligent terminal.

In the above embodiment, the loss of the uterine distention medium is calculated in real time according to the data results obtained by the first liquid flow sensor and the second liquid flow sensor, specifically by using the following formula:

V＝V1-V2

wherein V is the loss of the uterine distention medium, V1 is the data result obtained by the first liquid flow sensor, and V2 is the data result obtained by the second liquid flow sensor.

In the above embodiment, the correspondingly controlling the working states of the double-wheel uterine expansion pump and the intelligent terminal specifically includes controlling the double-wheel uterine expansion pump to stop pumping water, and controlling the intelligent terminal to alarm. Certainly, in order to improve the safety and controllability of the operation, if the operation duration exceeds a preset threshold value, the double-wheel uterine expansion pump is controlled to stop pumping water, and the intelligent terminal is controlled to remind. Preferably, the timing is performed at the beginning of the operation and is displayed simultaneously in the human-computer interaction interface time window. When the time is up to 40 minutes, the time window flickers for 5 seconds every 5 minutes, and when the time is up to 60 minutes, the time window flickers red, the sound and light alarm is given, and the liquid perfusion is suspended. The surgeon can choose to end the operation according to the situation, or continue the operation after the peristaltic wheel is recovered to operate and perfuse. The surgeon can set the warning starting time point, the interval warning time, the buffering time before pause and the like according to the actual situation, and the details are not repeated.
