[0023] In order to enable those skilled in the art to better understand the technical solutions in the utility model, the technical solutions for achieving the invention purpose of the utility model will be further described below through several specific embodiments. It should be noted that the technical solutions claimed for protection by the utility model include but are not limited to the following embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the utility model.

[0024] This embodiment discloses an integrated uterine distention fluid circulation system for hysteroscopy simulation training. Figure 1 As shown, the system is composed of a hysteroscopic surgical instrument 1, a mold placement box 2, a uterine distension machine 3, and a uterine distension fluid storage container 4; wherein the hysteroscopic surgical instrument 1 is used to perform hysteroscopic surgical operations, the mold placement box is used to place a uterine cavity mold that simulates the human uterine cavity, the uterine distension machine 3 is used to pressurize the uterine distension fluid and adjust the flow rate of the uterine distension fluid, and transport it to the hysteroscopic surgical instrument 1, and the uterine distension fluid storage container 4 stores uterine distension fluid. In the utility model, in order to realize the recycling of uterine distension fluid and reduce the cost of simulation training, the mold placement box 2 is connected to the uterine distension fluid storage container 4 through a water outlet pipe 7, and the uterine distension fluid storage container 4 is connected to the uterine distension machine 3 through a return pipe 9, and the uterine distension machine 3 is connected to the hysteroscopic surgical instrument 1 through a water inlet pipe 8. Furthermore, a horizontal placement plate 10 is provided inside the mold placement box 2, and the horizontal placement plate 10 divides the internal cavity of the mold placement box 2 into two layers, wherein the upper space is the mold placement bin 201, and the lower space is the uterine distension fluid collection bin 202. A uterine cavity mold is fixed in the mold placement bin 201, and an opening for a hysteroscopic surgical instrument 1 to pass through is provided on the front side wall of the mold placement bin 201. One end of the hysteroscopic surgical instrument 1 is located in the mold placement bin 201, and the other end is connected to the uterine distension machine 3 through a water inlet pipe 8; the uterine distension fluid storage container 4 and the uterine distension machine 3 are connected to the uterine distension fluid collection bin 202 through a water outlet pipe 7 and a water inlet pipe 8, respectively; and a channel 11 for fluid to pass through is provided on the horizontal placement plate 10.

[0025] When using this system for hysteroscopic surgery simulation training, the uterine cavity mold is placed on the horizontal placement board 10, and then the hysteroscopic surgical instrument 1 is installed in place, and the uterine distension machine 3 is turned on. The uterine distension machine 3 sucks the uterine distension fluid in the uterine distension fluid storage container 4 through the return pipe 9, and then transports the uterine distension fluid to the hysteroscopic surgical instrument 1 through the water inlet pipe 8. The medical staff operates the hysteroscopic surgical instrument 1 to simulate the corresponding uterine cavity surgery operation on the uterine cavity mold in the placement bin. During the simulated operation, the uterine distension fluid entering the mold placement bin 201 flows into the uterine distension fluid collection bin 202 below through the channel on the horizontal placement board, and then is discharged back to the uterine distension fluid storage container 4 through the outlet pipe 7, finally realizing the recycling of the uterine distension fluid during the hysteroscopic surgery simulated using the system.

[0026] In the embodiment described in the present invention, physiological saline is usually used as the uterine distension fluid for simulation training of hysteroscopic surgery.

[0027] In the embodiment described in the present invention, it is understood that the channel 11 for fluid to pass through can be a plurality of strip-shaped slots arranged on the horizontally placed plate 10, or a through hole of any shape such as a circle or a square. The present invention does not limit the specific shape and structure of the channel 11, whether it is a strip-shaped slot or a through hole, as long as the fluid can pass through.

[0028] In the embodiment described in the utility model, in order to improve the training effect and truly restore the actual hysteroscopic surgery operation process during the simulation training, the utility model filters the circulating uterine distension fluid entering the uterine distension fluid storage container 4, removes the tissue cut during the simulation operation and the impurities generated, and ensures that the uterine distension fluid injected during the simulation operation is clean. Specifically, the uterine distension fluid storage container 4 is composed of a two-part structure, including a storage container body 401 and a filtering mechanism 5 arranged in the storage container body 401. The filtering mechanism 5 divides the internal space of the storage container body 401 into two layers, the upper part is the filtering space, and the lower part is the storage space. Based on the above filtering structure, the outlet of the water outlet pipe 7 is located in the filtering space, and the inlet of the water return pipe 9 is located in the storage space. The uterine distension fluid discharged from the uterine distension fluid collection chamber 202 first enters the filtering space, and then the tissue cut during the operation is left in the filtering space of the upper layer. The clean liquid after filtration flows into the storage space of the lower part for storage, and then the clean uterine distension fluid enters the uterine distension machine through the water return pipe, so as to realize the reciprocating circulation of the uterine distension fluid.

[0029] It is understood that, referring to the attached manual Figure 3As shown, the filtering mechanism 5 is a filter screen 501 arranged in the storage container body 401. In order to achieve the fixation and quick disassembly of the filter screen 501, the inner wall of the storage container body 401 is circumferentially provided with a protruding step portion, and the bottom of the filter screen abuts against the step surface of the step portion, thereby achieving the fixation of the filter screen.

[0030] Furthermore, the filter 501 is composed of a filter plate and a filter wall enclosed around the filter plate, the filter wall is cylindrical, filter holes are arranged on the filter plate and the filter wall, and a cross bar is radially arranged on the filter wall, which acts as a handle of the filter. The filter can be quickly removed from the storage container body 401 by hooking the cross bar with fingers, thereby removing the substances filtered on the filter plate and the filter wall.

[0031] In the embodiments described in the present utility model, refer to the attached specification Figure 2 As shown, the mold placement chamber 201 is provided with a clamping mechanism 6 for fixing the uterine cavity mold. Specifically, the clamping mechanism 6 includes a clamping plate 601 and a card slot 602 arranged on the side walls of the mold placement chamber 202. In order to simplify the device structure, the number of the clamping plate 601 is one, and the sandwich space formed between the clamping plate 601 and the front side wall is the clamping and fixing space of the uterine cavity mold by cooperating with the front side wall of the mold placement chamber 201 (i.e., the side wall through which the hysteroscopic surgical instrument 1 passes). The top cover of the mold placement chamber 201 is detachable. The top cover of the placement chamber is opened, and the uterine cavity mold used in the simulation training process is placed in the sandwich space between the clamping plate 601 and the front side wall. After the uterine cavity mold is fixed, the system can be used for simulation training.

[0032] Furthermore, in order to better adapt to uterine cavity molds of different sizes, a plurality of the clamping slots 602 are provided along the length direction of the side walls on both sides of the mold placement chamber 202. When fixing the uterine cavity mold, the size of the interlayer space formed between the clamping plate 601 and the front side wall of the placement chamber can be changed by clamping the clamping plate 601 into the corresponding clamping slot 602, thereby fixing uterine cavity molds of different sizes.

[0033] It is understandable that in actual hysteroscopic surgery, improper injection of distension fluid can cause internal environmental disturbances in patients, which can easily lead to water intoxication and even death in severe cases. Therefore, how to accurately estimate the amount of distension fluid absorbed during surgery is particularly important to prevent patients from having internal environmental disturbances, and becomes a key factor in preventing water intoxication. Distension fluid is usually calculated by subtracting the amount injected from the amount collected. Therefore, in order to more realistically restore the actual surgical situation and further improve the simulation training effect of the system, the utility model also monitors the injection and collection amounts of distension fluid during the simulation training. Specifically, a first flow meter is provided on the water inlet pipe 8, and a second flow meter is provided on the water outlet pipe. The first flow meter is used to monitor the flow of the uterine distension fluid entering the uterine cavity mold, and the second flow meter is used to monitor the flow of the uterine distension fluid discharged from the uterine cavity mold. The two flow meters are respectively connected to the host computer of the entire system and transmit the monitored flow signals. The host computer obtains the injection and collection amounts of the uterine distension fluid during the simulated hysteroscopic surgery based on the signals of the two flow meters. The host computer can calculate the absorption amount of the uterine distension fluid by real-time monitoring of these two key data. When the absorption amount exceeds the limit, the host computer will alarm to prompt the medical staff.

[0034] In the implementation method described in the utility model, the utility model patent does not limit the flow meter, and the liquid flow meter currently available on the market can be used, for example, the flow meter of the LDC series produced by Shanghai Chikong Company can be used. The flow meter itself and flow monitoring are not improvements and innovations of the utility model, and will not be described and expanded in detail here.

[0036] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "setting", "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components.
