Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hysteroscopes, and particularly relates to a rapid exhaust device for a hysteroscope. Background Art
[0002] Hysteroscopy generally refers to hysteroscopic examination, which is a minimally invasive gynecological diagnosis and treatment technique. It is an examination using a hysteroscope to view the situation inside the patient's uterine cavity. Through the fiber optic glass fiber endoscope inserted into the uterine cavity, the physiological and pathological changes of the cervical canal, internal os of the cervix, endometrium, and fallopian tube openings can be directly observed. Diseased tissues can also be taken for pathological analysis, and treatment can also be directly carried out under hysteroscopic examination. In related technologies, during the diagnosis and treatment examination process, distending fluid needs to be injected into the uterine cavity to fill the uterus, and then the hysteroscope is used to observe or treat the filled and expanded uterus. However, when the distending fluid is first injected, due to the distending fluid itself or the equipment, there are a certain amount of bubbles in the distending fluid transported in the catheter, and the bubbles will decrease only after continuous transportation for a period of time. This results in the waste of the distending fluid transported during this period and also reduces the efficiency. Content of the Utility Model
[0003] The utility model aims to at least solve one of the technical problems existing in the prior art. For this purpose, the utility model provides a rapid exhaust device for a hysteroscope, which can quickly separate the bubbles generated by gas in the distending fluid, improve the efficiency when injecting the distending fluid, reduce waste, and increase the convenience of using the hysteroscope.
[0004] The rapid exhaust device for a hysteroscope according to the first aspect embodiment of the utility model includes a housing and a cover body. The upper section of the housing is cylindrical, and the lower section is inverted cone-shaped. A liquid inlet joint is arranged on the side of the housing, and the liquid inlet joint is used to pump the distending fluid through a delivery pipe. The lowest part of the housing is provided with a liquid outlet joint, and the liquid outlet joint is used to communicate with the hysteroscope through a delivery pipe. The cover body covers the top of the housing, and an exhaust pipe is arranged in the middle of the cover body. The axis of the exhaust pipe is collinear with the axis of the housing. The top of the exhaust pipe extends out of the top of the cover body, and the bottom extends into the housing and is located above the liquid outlet joint. The distending fluid flows into the housing from the liquid inlet joint, moves spirally downward along the circumference of the housing, and is discharged through the liquid outlet joint. The gas is precipitated and discharged through the exhaust pipe.
[0005] The rapid exhaust device for hysteroscope according to the embodiments of the present utility model has at least the following beneficial effects: The expansion liquid is pumped into the liquid inlet joint, and the expansion liquid with a certain pressure enters the interior of the housing. In cooperation with the structure that the upper part of the housing is cylindrical and the lower part is inverted conical, the expansion liquid moves along the inner wall of the housing. Under the action of gravity, a spiral water flow is formed and flows downward. The air in the expansion liquid is separated from the liquid under the action of centrifugal force and rotates downward. The rotating downward air flow continuously flows into the central part of the separator, forming a centripetal radial air flow. This part of the air flow forms a rotating upward inner swirl flow, with the same direction as the outer swirl flow. Finally, the air flow is discharged upward along the exhaust pipe, and the expansion liquid from which the air is separated flows out from the lower conical opening, realizing the separation of water and vapor. The injection efficiency of the expansion liquid is significantly improved, the surgical waiting time is reduced, the continuity and efficiency of surgical operations are improved, and moreover, since the gas is effectively separated and discharged, the waste of the expansion liquid caused by the presence of gas is avoided, which not only reduces the medical cost but also conforms to the concept of green medical treatment and reduces unnecessary resource consumption.

[0020] A hysteroscope generally refers to hysteroscopy, which is a minimally invasive gynecological diagnosis and treatment technique. It is an examination using a hysteroscope to view the conditions inside the patient's uterine cavity. By inserting a fiber-optic endoscope into the uterine cavity, it directly observes the physiological and pathological changes of the cervical canal, internal os of the cervix, endometrium, and fallopian tube openings. It can also take diseased tissues for pathological analysis and can also be directly treated under hysteroscopy. In the related art, during the diagnosis and treatment process, distending fluid needs to be injected into the uterine cavity to fill the uterus, and then the hysteroscope is used to observe or treat the filled and expanded uterus. However, when the distending fluid is first injected, due to the distending fluid itself or the equipment, there are a certain amount of air bubbles in the distending fluid transported in the catheter. It takes a certain period of continuous transportation for the air bubbles to decrease. This results in the distending fluid transported during this period being unusable, causing waste and reducing efficiency.
[0021] Therefore, with reference to Figure 1 and Figure 2, a rapid exhaust device for a hysteroscope proposed by the present utility model, includes a housing 100 and a cover 200. The upper section 101 of the housing 100 is cylindrical, and the lower section 102 is inverted conical. A liquid inlet joint 300 is provided on the side of the housing 100. The liquid inlet joint 300 is used to pump the uterine distension fluid through a delivery tube. A liquid outlet joint 400 is provided at the bottom of the housing 100. The liquid outlet joint 400 is used to communicate with the hysteroscope through a delivery tube. The cover 200 is covered on the top of the housing 100. A exhaust pipe 210 is provided in the middle of the cover 200. The axis of the exhaust pipe 210 is collinear with the axis of the housing 100. The top of the exhaust pipe 210 extends out of the top of the cover 200, and the bottom extends into the housing 100 and is located above the liquid outlet joint 400. The uterine distension fluid flows into the housing 100 from the liquid inlet joint 300, moves in a spiral downward along the circumferential direction of the housing 100, and is discharged through the liquid outlet joint 400. The gas is separated out and discharged through the exhaust pipe 210. It can be understood that the uterine distension fluid is pumped into the liquid inlet joint 300. The uterine distension fluid with a certain pressure enters the interior of the housing 100, and in cooperation with the structure that the upper part 101 of the housing 100 is cylindrical and the lower part 102 is inverted conical, the uterine distension fluid moves along the inner wall of the housing 100. Under the action of gravity, a spiral water flow is formed and flows downward. The air in the uterine distension fluid is separated out from the liquid under the action of centrifugal force and rotates downward. The rotating downward air flow continuously flows into the central part of the separator, forming a centripetal radial air flow. This part of the air flow forms a rotating upward inner swirl flow, and the direction is the same as that of the outer swirl flow. Finally, the air flow is discharged upward along the exhaust pipe, and the uterine distension fluid from which the air is separated flows out from the lower conical opening, realizing the separation of water and vapor. The injection efficiency of the uterine distension fluid is significantly improved, the surgical waiting time is reduced, the continuity and efficiency of the surgical operation are improved. And, since the gas is effectively separated and discharged, the waste of the uterine distension fluid caused by the presence of the gas is avoided, which not only reduces the medical cost, but also conforms to the concept of green medical treatment and reduces unnecessary resource consumption. On the other hand, the device has a compact structure, is easy to install and maintain, can be directly connected to the existing hysteroscope system without additional complex operations, greatly simplifies the surgical preparation process, improves the convenience and comfort of the doctor's operation, and at the same time reduces the risks that may be caused by equipment problems during the operation.
[0022] It should be noted that when the distending fluid (a liquid containing gas bubbles) is pumped into the housing 100 through the liquid inlet connector 300, due to the much lower density of the gas than the liquid, the bubbles will naturally rise to the upper layer of the liquid. The inverted conical design of the housing 100 further promotes the aggregation and rising of the bubbles, making it easier for the bubbles to be guided near the exhaust pipe 210. On the other hand, when the distending fluid flows spirally downward in the circumferential direction within the housing 100, a dynamic water flow field is formed. This spiral flow not only increases the degree of turbulence of the liquid, helps the bubbles detach from the liquid, but also makes the gas in the liquid more easily carried to the top area of the housing 100. At the same time, the coaxial design of the axis of the exhaust pipe 210 and the axis of the housing 100 ensures that the bubbles can be directly and efficiently discharged through the exhaust pipe 210 without affecting the normal flow and discharge of the liquid below.
[0023] Referring to Figure 2 , the liquid inlet connector 300 is tubular, and the axis of the liquid inlet connector 300 is tangent to the circumferential direction of the housing 100. Further, a flow guiding groove 120 is provided on the inner side wall of the housing 100. The flow guiding groove 120 is arranged around the liquid inlet connector 300 to guide the distending fluid to flow spirally downward along the circumferential direction of the housing 100. The liquid inlet connector 300 is designed to be tubular, and its axis is tangent to the circumferential direction of the housing 100. In this way, when the distending fluid enters the housing 100 through the liquid inlet connector 300, it will be subjected to a tangential force, which prompts the distending fluid to start flowing in the circumferential direction within the housing 100. A spiral flow guiding groove 120 is provided on the inner side wall of the housing 100. These flow guiding grooves 120 closely surround the liquid inlet connector 300 to ensure that the distending fluid can gradually descend in a spiral manner along the guidance of the flow guiding groove 120. The liquid inlet connector 300 is located at the uppermost part 101 of the side wall of the housing 100. Such a design can maximize the utilization of the space within the housing 100 and at the same time ensure that the distending fluid starts its spiral downward movement when it enters the housing 100. By making the liquid inlet connector 300 tangent to the circumferential direction of the housing 100 and combining it with the flow guiding groove 120, the distending fluid can immediately start its spiral downward movement after entering the housing 100, greatly enhancing the hydrodynamic effect and promoting the effective separation of gas and liquid.
[0024] Preferably, the liquid inlet connector 300 is located at the uppermost part of the side wall of the housing 100, thereby maximizing the travel of the distending fluid within the housing 100 and thus maximizing the gas separation effect.
[0025] Optionally, in some embodiments, a one-way valve is provided in the exhaust pipe 210. The one-way valve is located at a position near the top of the exhaust pipe 210 to ensure that the gas can only be discharged from the housing 100 to the outside world, and the outside air will not enter the housing 100 to contaminate the distending fluid, ensuring the use safety.
[0026] Referring to Figure 1 and Figure 2, a first side plate 110 is circumferentially provided at the top of the housing 100, and a second side plate 220 is circumferentially provided at the bottom of the cover 200. A number of fixing holes are provided at corresponding positions on the first side plate 110 and the second side plate 220, and the fixing holes are used for passing through fasteners to fix the housing 100 and the cover 200. A number of fixing holes are respectively provided at corresponding positions on the first side plate 110 and the second side plate 220, and these fixing holes are used for passing through fasteners (such as screws, bolts, etc.) to tightly fix the housing 100 and the cover 200 together. This not only simplifies the installation process but also improves the sealing performance of the device and the stability of the overall structure.
[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention.
