Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a uterine expansion instrument. Background Art

[0002] Hysteroscopic surgery is one of the common surgical procedures in gynecological surgery. During hysteroscopic surgery, it is usually necessary to use distending fluid (usually saline) to fill the patient's uterine cavity, thereby exposing a larger field of view and better cooperating with image acquisition equipment such as electronic mirrors and optical mirrors, so that medical staff can find the lesions. In addition, when using planing equipment to remove lesions, distending fluid is also needed to flush the lesion site. Although distending fluid can better assist surgical operations, if the patient absorbs too much distending fluid, there may be a risk of acute water intoxication and other complications. Therefore, when performing hysteroscopic surgery, the amount of distending fluid in and out must be monitored so that medical staff can know in time whether the patient has absorbed too much distending fluid and ensure the patient's life safety.

[0003] Currently, clinically used image acquisition devices, such as electronic and optical scopes, can not only capture images but also inject distending fluid into the patient's uterine cavity and remove waste fluid from the uterine cavity. Specifically, the operating handles of electronic and optical scopes are equipped with channels for injecting distending fluid and removing waste fluid. Furthermore, clinically used planing devices can not only remove lesions but also remove waste fluid and tissue from the uterine cavity. Specifically, the planing devices are equipped with channels for removing waste fluid and tissue. Therefore, waste fluid generated during surgery may have multiple outlets.

[0004] Accurately monitoring the output of waste fluid is an important prerequisite for accurately calculating the input and output of uterine distension fluid.

[0037] like Figure 1-Figure 3 As shown, the embodiment of the present application provides a distending device, comprising a main unit 1, a second weight sensor 3, and a liquid pump unit. The main unit 1 is provided with a main control system MCU 4 for controlling the operation of all electrical components of the distending device and the operation of the built-in algorithm program.

[0038] In this embodiment, the main unit 1 is provided with a first hook 5 for hanging a waste liquid collection container 2. It should be noted that the waste liquid collection container 2 is a structure used in conjunction with the uterine distension device and is used to hold waste liquid generated during surgery. The waste liquid collection container 2 is mainly a bag commonly used in clinical practice and is relatively light in weight.

[0039] The second weight sensor 3 is installed on the host 1, specifically set at the position of the first hook 5, for collecting the weight data of the waste liquid collection container 2 and transmitting the weight data to the main control system MCU4 for processing, so as to monitor the waste liquid generated during the operation in real time and accurately.

[0040] The liquid pump unit is installed on the host 1 and is electrically connected to the main control system MCU4, and is controlled by the main control system MCU4. The liquid pump unit includes an infusion pump 6, a first suction pump 7, a second suction pump 15, and a third suction pump 8. The infusion pump 6 is used to inject uterine distension fluid into the patient's uterine cavity, and the first suction pump 7, the second suction pump 15, and the third suction pump 8 are used to transport waste fluid generated during surgery to the waste fluid collection container 2. The infusion pump 6 can correspond to an image acquisition device, and the uterine distension fluid can be injected into the patient's uterine cavity through the image acquisition device. The first suction pump 7 and the second suction pump 15 can correspond to an image acquisition device and a planing device 10, respectively, and the waste fluid generated during surgery can be transported to the waste fluid collection container 2 through the image acquisition device and the planing device 10. The third suction pump 8 is mainly used to transport waste fluid overflowing from the uterine cavity during surgery to the waste fluid collection container 2.

[0041] By adopting the above-mentioned technical solution, the waste liquid generated during the operation can be transported to the waste liquid collection container 2 through multiple channels for unified management, and the output of the waste liquid can be monitored in real time to ensure the accuracy of the subsequent calculation of the input and output of the uterine distension fluid, thereby reducing the risk of the operation and ensuring the patient's life safety.

[0042] It should be noted that the image acquisition equipment associated with the distending device in this embodiment primarily comprises an electronic scope 24 and an optical scope 9. Both are designed with channels for inputting distending fluid and discharging waste fluid. The planing device 10 associated with the distending device in this embodiment also has channels for discharging waste fluid and for cutting tissue.

This arrangement enables real-time monitoring of the amount of distending fluid introduced into the patient's uterine cavity during surgery.

[0046] In addition, when the main control system MCU4 receives the weight data of the uterine distension fluid container 23 collected by the first weight sensor 13 and the weight data of the waste liquid collection container 2 collected by the second weight sensor 3, it can calculate the input and output of the uterine distension fluid based on the built-in algorithm, thereby monitoring the input and output of the uterine distension fluid in real time, thereby reducing the risk of surgery and ensuring the patient's life safety.
