Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a liquid collection device for hysteroscopy. Background Technology

[0002] In gynecological clinical diagnosis and treatment, hysteroscopy is a widely used endoscopic technique. During the procedure, distending fluid is continuously injected into the patient's uterine cavity to expand the cavity, provide a clear view, and flush away tissue debris, blood, and endometrium. The resulting large amount of mixed outflow fluid needs to be effectively collected and treated. This is not only related to maintaining surgical cleanliness and preventing cross-infection, but also, with the development of precision medicine and rapid postoperative diagnosis, the demand for immediate or in vitro pathological and biochemical testing of these recovered fluids is becoming increasingly prominent. These indicators include specific tumor markers, inflammatory factors, and drug metabolic concentrations.

[0003] However, the hysteroscopic fluid collection devices widely used in clinical practice are usually simple collection bags, buckets, or bottles. For example, application number 202410975239.4, entitled "A Fluid Collection Device for Hysteroscopic Surgery," can collect the distension fluid mixture during surgery in a timely manner. However, it has certain shortcomings in meeting the needs of modern surgery and testing. On the one hand, its installation adaptability is poor. Existing devices are mostly suspended from the operating table rail or IV stand by hooks, or placed directly on the ground. This fixing method is unstable and has poor adjustability, making it difficult to adapt to different operating table heights, specific patient positions, and surgeon's operating habits. It cannot optimize the efficiency of gravity-based drainage, and sometimes even... Improper height can lead to poor drainage or backflow. On the other hand, when conducting biochemical tests on the collected liquid, sample temperature is a key pretreatment factor affecting the accuracy of the test results. Many biomarkers, such as enzymes, active proteins, and cell morphology, are sensitive to temperature fluctuations after being removed from the in vivo environment. Existing collection devices are simply storage containers without temperature control functions, which can cause changes in the activity or degradation of certain components, thus introducing detection errors. If the container is simply heated as a whole, it is difficult to avoid local overheating or undercooling areas caused by uneven heat conduction. Such temperature gradients can also damage the uniformity and representativeness of the sample, affecting the reliability of the test data. Summary of the Invention

[0004] To address the aforementioned problems, the main objective of this invention is to provide a hysteroscopic liquid collection device that can be stably and flexibly installed on the operating table base and whose position can be adaptively adjusted to adapt to complex surgical environments.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] First Embodiment like Figure 1The diagram shows the structure of the hysteroscopic fluid collection device of the present invention. In this embodiment, the hysteroscopic fluid collection device includes a positioning structure, an adjustment structure, a fixing structure, and a collection device body. The positioning structure includes a bottom support frame 11 and a clamping member 12. The clamping member 12 is installed on the base of the operating table. Specifically, the clamping member 12 includes a bottom plate 121, a side plate 122, a top plate 123, and a positioning rod 124. The bottom plate 121, side plate 122, and top plate 123 are arranged in a square structure. The side plate 122 is fixed to one side of the bottom plate 121, and the top plate 123 is fixed to the top surface of the side plate 122. The top plate 123 has a threaded hole, and the positioning rod 124 is screwed into the threaded hole. The lower end of the positioning rod 124 has a buffer pad. By rotating the positioning rod 124, the position of the buffer pad at the bottom of the positioning rod 124 can be adjusted. Thus, the positioning rod 124 fixes the positioning rod to the side of the base at the bottom of the operating table, and the installation position can be adjusted. In addition, in this embodiment, the bottom support frame 11 is installed on the side plate 122 opposite to the bottom plate 121. The bottom of the bottom support frame 11 is provided with a support block 111, which is in contact with the ground and provides stable support force for the entire device.

[0026] Please see Figure 1 and Figure 2 As shown, in this embodiment, the adjusting structure includes a lifting rod 21 and a mounting block 22. The lower end of the lifting rod 21 is rotatably mounted inside the bottom support frame 11, and the mounting block 22 is movably sleeved on the lifting rod 21. In this embodiment, the mounting block 22 has a vertically arranged mounting hole with an internal thread structure on the inner wall of the mounting hole. The lifting rod 21 has an external thread structure 211, which cooperates with the internal thread structure. The upper end of the lifting rod 21 has a rotating part 212. By rotating the rotating part 212, the lifting rod 21 can be rotated, thereby adjusting the height of the mounting block 22. In other embodiments, the mounting block 22 has an electromechanical compartment (not shown in the figure) inside, which contains a drive mechanism and a drive gear. The lifting rod 21 has an external thread structure 211, and a driven gear is sleeved at any position on the external thread structure 211 of the lifting rod 21. The center hole of the driven gear meshes with the external thread structure 211 of the lifting rod 21, and the drive gear drives the driven gear to rotate, thereby driving the rotation of the lifting rod 21.

[0027] Please see Figure 1 and Figure 2As shown, in this embodiment, the fixed structure includes a first square tube 31, a second square tube 32, and a support member 33. The second square tube 32 is movably fitted inside the first square tube 31, and the support member 33 is fixedly connected to the second square tube 32. The first square tube 31 has several vertically distributed first through holes 311, and the second square tube 32 has several vertically distributed second through holes 321. The overlapping first through holes 311 and second through holes 321 are provided with fixing bolts 34. The position of the support member 33 can be adjusted by adjusting the position of the fixing bolts 34. The support member 33 is used to fix the collection device body, thereby adjusting the position of the collection body.

[0028] Therefore, the hysteroscopic fluid collection device in this embodiment is equipped with a positioning structure and an adjustment structure. The two work together to stably install and fix the bottom of the collection device on any side of the operating table base, while the adjustment structure can adaptively adjust the height and position of the collection device body, and the adjustment process is simple.

[0029] Second Embodiment like Figure 4 As shown, in this embodiment, the main body of the collection device is provided with a liquid collection chamber 41, a constant temperature chamber 42, a constant temperature stirring system, and a heating element 43. The constant temperature chamber 42 is sleeved on the outer wall of the liquid collection chamber 41. The constant temperature stirring system and the heating element 43 are used to maintain the temperature of the constant temperature chamber 42. In this embodiment, the support member 33 is provided with a support plate 331, a bottom clamping plate 332, and a limiting ring 333. The support plate 331 has a U-shaped structure. The bottom clamping plate 332 and the limiting ring 333 are fixedly connected to the bottom and top of the support plate 331, respectively. The heating element 43 is fixedly installed on the support plate 331. The constant temperature chamber 42 is located inside the limiting ring 333, and its bottom is located inside the bottom clamping plate 332.

[0030] Please refer to the figure. Figure 4 and Figure 5As shown, in this embodiment, the constant temperature stirring system is provided with a first inner wall gear 51, a stirring shaft 52, a second inner wall gear 53, a limiting member 54, a drive motor 55, and a driving gear 56. The upper end of the stirring shaft 52 is provided with a first connecting gear 57, which meshes with the first inner wall gear 51. The top of the constant temperature chamber 42 and surrounding the outer periphery of the liquid collection chamber 41 is provided with an adjusting chamber 60. The top of the constant temperature chamber 42 is provided with an annular notch 61, and the adjusting chamber 60 and the constant temperature chamber 42 are connected through the annular notch 61. The second inner wall gear 53 is rotatably disposed on the outer periphery of the bottom of the regulating chamber 60. A connecting rod 58 is provided at the top center of the first connecting gear 57. The connecting rod 58 passes through the annular notch 61 and connects to the bottom center of a second connecting gear. The second connecting gear meshes with the second inner wall gear 53. The second inner wall gear 53, the limiting member 54, and the driving gear 56 are all located inside the regulating chamber 60. The drive motor 55 is installed on the top of the regulating chamber 60. The output end of the drive motor 55 is fixedly connected to the central shaft of the driving gear 56. The driving gear 56 meshes with the second inner wall gear 53. In addition, in this embodiment, the top of the liquid collection chamber 41 is provided with a collection pipe 70, and the bottom is provided with a liquid outlet pipe 80. A valve 81 is provided on the liquid outlet pipe 80.

[0031] In this embodiment, during the use of the collection device, under negative pressure or gravity, the liquid mixed with distending fluid is transported to the collection tube 70 and enters the liquid collection chamber 41. Prior to this, the constant temperature chamber 42 is filled with constant temperature liquid, which is heated to body temperature by the heating element 43. The heated liquid can be made to uniformly temperatured by the constant temperature stirring system, which can keep the liquid collection chamber 41 at a relatively stable temperature. During the operation, the accuracy of the bioactivity indicators and some detection indicators of the liquid sample will not be affected by temperature changes. Furthermore, the constant temperature system in this invention does not directly heat the liquid sample. Instead, the constant temperature stirring system can make the liquid sample temperature more uniform, keeping the liquid sample in a uniform, stable temperature range close to physiological body temperature. This maximizes the preservation of the sample's bioactivity and the authenticity of the detection indicators, laying a reliable foundation for subsequent accurate detection.

[0032] Specifically, in this embodiment, the drive motor 55 is activated to drive the drive gear 56 to rotate. The drive motor 55 is fixed to the adjustment chamber 60, and the drive gear 56 is rotatably fixed inside the adjustment chamber 60. Furthermore, since the drive gear 56 meshes with the second inner wall gear 53, and the bottom of the second inner wall gear 53 has a protrusion 531, while the bottom surface of the adjustment chamber 60 has an annular groove 62, the protrusion 531 can rotate within the annular groove 62. Thus, the drive gear 56 drives the second inner wall gear 53 to rotate, and simultaneously the second connecting gear 59 begins to rotate. In addition, the second inner wall gear... The center of 53 moves around the center of the circle; it should be noted that in this embodiment, the first inner wall gear 51 and the second inner wall gear 53 have the same structure, and the first connecting gear 57 and the second connecting gear 59 also have the same structure. Therefore, the rotation and movement trajectory of the first connecting gear 57 and the second connecting gear 59 connected to the bottom of the second connecting gear 59 are the same. This drives the stirring shaft 52 to rotate while moving along the above trajectory. The stirring shaft 52 is equipped with stirring blades, which can fully stir the liquid in the constant temperature chamber 42, improve the temperature stability in the constant temperature chamber 42, and prevent uneven temperature.

[0033] Third Embodiment The difference between this embodiment and the previous embodiment is that the bottom of the constant temperature chamber 42 in this embodiment is provided with a built-in retaining ring 421, and the bottom of the stirring shaft 52 is provided with a retaining member 521. The retaining member 521 moves within the built-in retaining ring 421, and the retaining member 521 will not disengage from the built-in retaining ring 421. This provides a limiting effect on the movement of the stirring shaft 52 and improves its movement stability. It should be noted that the bottom of the stirring shaft 52 and the retaining member 521 are rotatably connected, so the rotation of the stirring shaft 52 will not be affected during the movement.

[0034] Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
