Description

Technical Field

[0001] The invention belongs to the technical field of human body fluid collection, and in particular relates to a device for collecting and measuring uterine distension fluid during hysteroscopic surgery. Background Art

[0002] Hysteroscopic surgery refers to minimally invasive surgery performed with a hysteroscope. Hysteroscope is an advanced device for diagnosing and treating diseases in the uterine cavity. It can clearly observe various changes in the uterine cavity and make a clear diagnosis. During hysteroscopic surgery, it is necessary to first inject distension fluid into the uterine cavity to fill the uterus and form an ideal visual space. Because the distension fluid continuously injected into the human body will be absorbed by the human body, if the amount absorbed is too much, it will cause water poisoning and even threaten life. Therefore, during the operation, it is necessary to monitor the amount of distension fluid absorbed by the human body in real time (usually the amount of distension fluid injected into the human body minus the amount of fluid discharged by the human body).

[0003] At present, the method of measuring the liquid discharged from the human body is usually to collect the liquid discharged from the human body in a container with a scale to directly measure the volume, or to collect the liquid in a collection bag and convert it to obtain the volume by measuring the weight. If a container is used to collect the liquid discharged from the human body during the operation, there is a problem of overflowing the container, and the liquid in the container needs to be packaged and transferred after the operation to avoid contamination. If a collection bag is used to collect the liquid discharged from the human body, it does not need to be packaged again, but when weighing the weight of the collection bag and the liquid therein, an electronic hanging scale is usually used for weighing. If the capacity of the collection bag is too large, it is easy to deform or even break during the long hanging process. Therefore, multiple collection bags are usually needed to collect distending fluid during the operation. This requires someone to observe whether the liquid in the collection bag is full in real time during the operation and replace it in time. If the observer is negligent, the liquid discharged from the human body cannot be collected in time, affecting the accuracy of the statistics, and then affecting the operation process. Therefore, it is necessary to improve the liquid collection and measurement method. Summary of the invention

[0004] In order to solve the above-mentioned defects of the prior art, the present application provides a hysteroscopic surgery distension fluid collection and metering device, which can automatically switch the collection bag to collect the fluid discharged by the human body during the hysteroscopic surgery, and can automatically measure the weight of the collected fluid without manual monitoring and weighing.

DETAILED DESCRIPTION

[0033] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the implementation modes of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] The present application embodiment provides a device for collecting and measuring uterine distension fluid during hysteroscopic surgery, such as Figure 1-Figure 9 As shown, it includes a liquid accumulation basin 1, an electronic hanging scale 2, a driving mechanism 5, a rotating disk 201, etc.

[0035] Specifically, the bottom of the effusion basin 1 is connected to the front end of an infusion tube 101, and a plug 102 is provided at the rear end of the infusion tube 101; the electronic hanging scale 2 is arranged in a hollow rotating disk 201, and the rotating disk 201 is driven by a rotating mechanism, and the rotating disk 201 is rotatably arranged in an annular shell 3, and the annular shell 3 is arranged on one side of the effusion basin 1, and a plurality of fixing components are arranged in a circular array at the bottom of the annular shell 3, and the hanging end of the electronic hanging scale 2 extends out of the bottom of the rotating disk 201 and is connected to a connecting disk 202, and a plurality of hooks 203 are arranged in a circular array at the bottom of the connecting disk 202, and a collecting device is hung on the hook 203 Bag 4, the collecting bag 4 is connected to a liquid inlet pipe 401, and the multiple liquid inlet pipes 401 are respectively fixed on multiple fixed components, and the outward end of the liquid inlet pipe 401 is provided with a joint 402 matching the plug 102, and the axial direction of the joint 402 is parallel to the radial direction of the annular shell 3; the pushing mechanism 5 is arranged on the outer side of the annular shell 3, and the telescopic end of the pushing mechanism 5 is connected to the plug 102, and the axial direction of the plug 102 is parallel to the radial direction of the annular shell 3. When the rotating disk 201 rotates to any one of the joints 402 toward the plug 102, and the telescopic end of the pushing mechanism 5 is fully pushed out, the plug 102 is inserted into the joint 402.

[0036] In actual use, before the operation, multiple collection bags 4 are hung on multiple hooks 203, and then the liquid inlet tubes 401 of the multiple actual bags are fixed to multiple fixed components. The rotating mechanism is controlled to drive the rotating disk 201 to rotate until any joint 402 is facing the plug 102, and the telescopic end of the pushing mechanism 5 is controlled to be fully pushed out so that the plug 102 is inserted into the joint 402. During the operation, the liquid discharged by the human body during the hysteroscopic operation flows into the fluid collection basin 1, and the liquid will flow into the collecting bag 4 connected to it through the infusion tube 101. When the liquid collected in the collecting bag 4 is full, the hanging end of the electronic hanging scale 2 will be subjected to a certain gravity. At this time, the telescopic end of the pushing mechanism 5 is controlled to retract, and then the rotating mechanism is controlled to drive the rotating disk 201 to rotate until the connector 402 of the next collecting bag 4 is aligned with the plug 102, and then the telescopic end of the pushing mechanism 5 is controlled to push the plug 102 into the connector 402 to continue collecting liquid. After the collecting bag 4 is full, the above steps can be repeated to replace the collecting bag 4 again to collect the liquid. Because multiple collecting bags 4 are suspended on the connecting disk 202, and the connecting disk 202 is connected to the hanging end of the electronic hanging scale 2, the total weight of all suspended collecting bags 4 and the liquid therein can be directly weighed to calculate the amount of uterine distension fluid absorbed by the human body.

[0037] Specifically, a driving motor 9 may be directly disposed above the annular housing 3 to drive the rotating disk 201 to rotate. In one embodiment, refer to Figure 1 , Figure 2The rotating mechanism includes a motor 9, a gear 901, and a ring gear 902. The ring gear 902 is sleeved on the outside of the rotating disk 201. The motor 9 is fixed on the annular shell 3. A notch is opened on the side of the annular shell 3. The gear 901 is arranged at the notch, and the gear 901 is meshed and connected with the ring gear 902. The output shaft of the motor 9 is connected to the gear 901. The gear 901 with fewer teeth drives the ring gear 902 with more teeth to rotate, which is convenient for more accurate control of the rotation angle of the rotating disk 201, so that the connector 402 is aligned with the plug 102.

[0038] For details, see Figure 3 , Figure 5 , Figure 6 The fixing component is a U-shaped fixing head 6. The tops of the two vertical sections of the U-shaped fixing head 6 are connected to the annular housing 3. The top of the transverse section of the U-shaped fixing head 6 is provided with a receiving groove 601. The width of the receiving groove 601 matches the diameter of the joint 402. The joint 402 is in the receiving groove 601. Figure 4 Two convex rings 4021 are provided outside the joint 402 at intervals. The two convex rings 4021 are respectively located on both sides of the U-shaped fixing head 6 to prevent the joint 402 from tilting after being inserted into the accommodating groove 601. The diameter of the convex ring 4021 is set to be smaller than the distance between the two vertical sections of the U-shaped fixing head 6, so that the convex ring 4021 can directly pass through the U-shaped fixing head 6, which is convenient for removing and replacing the collection bag 4 after the operation.

[0039] For more details, see Figure 2 , Figure 3 A pressing rod 602 is provided in the U-shaped fixing head 6, and a plurality of through holes are provided in a circular array on the rotating disk 201. A plurality of pressing rods 602 are inserted into the plurality of through holes, and the top of the pressing rod 602 protrudes from the top of the rotating disk 201. The pressing rod 602 is driven by a pressing mechanism provided above the rotating disk 201. The pressing mechanism can press down a plurality of pressing rods 602 at the same time, and press the connector 402 down to abut the bottom of the accommodating groove 601, so that the connector 402 maintains the same axial direction as the plug-102, thereby preventing the connector 402 from moving upward and being unable to connect with the plug-102.

[0040] Preferably, see Figure 2 , Figure 3 , Figure 7The pressing mechanism includes a plurality of pressing blocks 7. A plurality of connecting blocks 701 are arranged in a circular array on the top of the annular shell 3. The plurality of pressing blocks 7 are arranged on one side of the plurality of connecting blocks 701 facing the center of the annular shell 3, and the bottom of the plurality of pressing blocks 7 has an inclined surface 702. When the rotating disk 201 rotates to any one of the connectors 402 facing the plug 102, the tops of the plurality of pressing rods 602 abut against the lower ends of the plurality of inclined surfaces 702, and the pressing rods 602 press the connector 402 down to abut against the bottom of the accommodating groove 601. The pressing rods 602 can be controlled by a power source of the rotating mechanism to press the connector 402 tightly, and no additional power source is required. A first spring 703 is sleeved on the pressing rod 602, and the bottom of the first spring 703 is connected to the annular shell 3, and the top of the first spring 703 is connected to the pressing rod 602. When the pressing rod 602 presses the joint 402 down to abut the bottom of the accommodating groove 601, the first spring 703 is in a compressed state. When the collecting bag 4 needs to be replaced after the operation, the rotating mechanism is controlled to drive the rotating disk 201 to rotate, so that the pressing rod 602 rotates to disengage from the inclined surface 702, and the pressing rod 602 can move upward under the drive of the first spring 703. At this time, the joint 402 can be moved upward and taken out.

[0041] In the process of collecting liquid, when the pushing mechanism 5 drives the plug 102 to separate from the connector 402 of the collection bag 4, the liquid in the infusion tube 101 may flow out. A valve can be set to close the front end of the infusion tube 101 to prevent the liquid from flowing out. Figure 7-Figure 9 The bottom of the annular housing 3 is rotatably connected with a pair of vertical plates 8 through a pair of rotating shafts 801. The plug 102 is fixed in a push block 501. The push block 501 is connected to the telescopic end of the pushing mechanism 5. The push block 501 is in the pair of vertical plates 8, and the rotating shaft 801 is on the side of the push block 501 facing the effusion basin 1. When the telescopic end of the pushing mechanism 5 is fully retracted, the push block 501 pushes the vertical plates 8 to rotate around the rotating shaft 801 to press the infusion tube 101 tightly, and no additional valve is required to close the rear end of the infusion tube 101. Specifically, a second spring 802 is connected between the pair of vertical plates 8. When the vertical plates 8 press the infusion tube 101 tightly, the second spring 802 is in a stretched state. When the push block 501 is pushed out by the driving of the pushing mechanism 5, that is, when the plug 102 is inserted into the connector 402, the second spring 802 will drive the pair of vertical plates 8 to reset. At this time, the rear end of the infusion tube 101 is no longer squeezed by the vertical plates 8, and the liquid in it can flow into the collection bag 4.

[0042] Preferably, see Figure 1, the height of the rear end of the infusion tube 101 is higher than the height of the front end of the infusion tube 101, so that the infusion tube 101 is U-shaped after being connected to the liquid inlet tube 401 of the collection bag 4, so that the liquid in the infusion tube 101 will flow into the liquid inlet tube 401 of the collection bag 4 only after it is filled with liquid. When the amount of liquid discharged by the human body is counted in real time, the amount of liquid in the infusion tube 101 can be regarded as a fixed amount, and added to the amount of liquid in the collection bag 4 as the amount of liquid discharged by the human body, which can improve the accuracy of statistics compared to directly adding the amount of liquid in the collection bag 4 as the amount of liquid discharged by the human body. However, after the operation is completed and the collection bag 4 is removed, some liquid will still remain in the infusion tube 101, which needs to be manually discharged, which increases the workload.

[0043] As a further preferred embodiment, see Figure 1 , Figure 7 , a plurality of support columns 1001 are vertically arranged at the bottom of the annular housing 3, a support plate 10 is vertically arranged at the bottom of the support columns 1001, a plurality of telescopic rods 1002 are vertically arranged at the bottom of the support plate 10, and the plurality of telescopic rods 1002 are arranged on a fixed plate 11, and a lifting mechanism 12 is arranged between the fixed plate 11 and the support plate 10 to drive the support plate 10 to move up and down. When the operation is finished, the lifting mechanism 12 is controlled to drive the support plate 10 to move downward, so that the height of the rear end of the infusion tube 101 is lower than the height of the front end, so that the liquid in the infusion tube 101 can flow into the collection bag 4.

[0044] For details, see Figure 1 The effusion basin 1 is fixed on the fixed plate 11 through a fixing frame 103, and two pairs of universal wheels 13 are provided at the bottom of the fixed plate 11. In this way, the entire device is fixed on the fixed plate 11 in an integrated manner, and the universal wheels 13 facilitate the movement of the device.

[0045] The above description is only a preferred embodiment of the present invention, and is not intended to be the only one or to limit the present invention. Those skilled in the art should understand that various changes or equivalent substitutions made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
