Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a biodegradable support diaphragm device for preventing intrauterine adhesions. Background Technology

[0002] Intrauterine adhesions occur when trauma to the uterus, whether during pregnancy or not, damages the basal layer of the endometrium, causing partial or complete blockage of the uterine cavity. This can lead to menstrual abnormalities, infertility, or recurrent miscarriages. Symptoms of intrauterine adhesions are often not typical, mainly involving changes in menstruation, such as scanty menstruation, amenorrhea, or dysmenorrhea. Due to the serious consequences of intrauterine adhesions, most women undergoing abortion or curettage choose to use a diaphragm to prevent their recurrence.

[0003] Existing biodegradable support diaphragm devices for preventing intrauterine adhesions generally include a biodegradable support diaphragm and a placement structure. However, the existing placement structure can only be used after hysteroscopic observation is completed, and the device cannot be used to clean the hysteroscope and the insertion end of the diaphragm placement structure in real time during use.

[0004] The information disclosed in the background section is only intended to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a biodegradable support diaphragm device for preventing intrauterine adhesions. By driving the push mechanism and the real-time cleaning mechanism to work synchronously through a linkage mechanism, it can not only achieve real-time cleaning of the surface of the hysteroscope and the movable cannula of the diaphragm installation structure and the hysteroscope in an intermittent rightward movement, but also allow the hysteroscope to be used in conjunction with the diaphragm installation structure, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a biodegradable support diaphragm device for preventing intrauterine adhesions, comprising a base and a mounting platform fixedly disposed on the top of the base, wherein two vertically arranged perforations are provided through the mounting platform.

[0007] Preferably, a fixing tube is provided on the top of the mounting platform, and a pushing mechanism is located at the upper end of the mounting platform.

[0008] Priority is given to a real-time cleaning mechanism located at the end of the fixed pipe furthest from the mounting platform, and a linkage mechanism is provided between the push mechanism and the real-time cleaning mechanism.

[0009] Preferredly, the fixed tube has a push port at the position corresponding to the push mechanism and a cleaning port at the position corresponding to the real-time cleaning mechanism.

[0010] Preferably, a movable sleeve is movably fitted inside the fixed tube, and a supporting diaphragm tube is movably fitted inside the movable sleeve.

[0011] Preferably, a hysteroscopy tube is movably inserted inside the supporting diaphragm tube. An eyepiece is installed at one end of the hysteroscopy tube and a hysteroscopy lens is installed at the other end. The outer periphery of the supporting diaphragm tube near the hysteroscopy lens is covered with a supporting diaphragm.

[0012] The technical effects and advantages of this invention are as follows:

[0013] 1. This invention uses double-sided cams on a linkage mechanism to repeatedly push trapezoidal block two upwards to squeeze trapezoidal block one, causing trapezoidal block one to move to the right and, in conjunction with spring one, to push the movable cannula containing the diaphragm installation structure and hysteroscope to move intermittently to the right. At the same time, the rotation of a single-sided cam drives the lower circular plate to swing left and right, and under the transmission of bevel gears, drives the upper circular plate to swing left and right. This achieves real-time cleaning of the surface of the movable cannula containing the diaphragm installation structure and hysteroscope while it moves intermittently to the right, thus avoiding infection during the operation.

[0014] 2. By placing the diaphragm installation structure inside the movable sleeve and the hysteroscope inside the supporting diaphragm tube, the present invention allows the diaphragm installation structure and the hysteroscope to enter the uterine cavity simultaneously with the insertion end of the movable sleeve, enabling the hysteroscope to be used in conjunction with the diaphragm installation structure, which is precise and convenient to operate.

[0015] 3. By setting a telescopic rod at the bottom of the push assembly, the present invention can press the second round rod according to actual use needs, so that the second limiting strip at the bottom of the inner circumference of the slot on the second round rod moves along the limiting strip to separate from the second limiting strip. Then, by rotating the second round rod, the pushing direction of the push assembly can be adjusted, which is convenient and quick to operate.

[0016] 4. By emitting waves to secretions using ultrasound, the water content of the tissue or secretion is determined according to a preset ratio based on the ultrasound return value. When identifying secretions with ultrasound, if the water content of the secretion increases, the water will absorb more ultrasound energy, resulting in a decrease in the ultrasound echo. Conversely, if the water content decreases, the echo will increase. The echo value of the ultrasound is proportionally distributed to different types of secretions with different water contents, thereby improving the convenience of secretion identification.

[0035] Refer to the instruction manual appendix Figure 1-5 and Figure 8-13An embodiment of the present invention provides a biodegradable support diaphragm device for preventing intrauterine adhesions, comprising a base 1 and a mounting platform 2 fixedly disposed on the top of the base 1.

[0036] Furthermore, the push mechanism 4 includes a baffle 41 and a crossbar 42 fixedly connected to the baffle 41 and movably passing through the upper end of the mounting platform 2. A trapezoidal block 44 is fixedly provided at the end of the crossbar 42 away from the baffle 41. A spring 43 is movably sleeved on the outer periphery of the crossbar 42 between the baffle 41 and the mounting platform 2. A crossbar 45 is fixedly provided on the side of the mounting platform 2 away from the baffle 41 and movably fits against the top surface of the trapezoidal block 44. Horizontal ear plates 46 are fixedly provided on both the front and rear sides of the crossbar 45. An inverted U-shaped plate 47 is fixedly mounted between the top surfaces of the two horizontal ear plates 46. A telescopic rod 49 is provided at the top of the U-shaped plate 47, and a push assembly 48 is provided at the top of the telescopic rod 49.

[0037] Furthermore, the real-time cleaning mechanism 5 includes a left arc plate 51 and a right arc plate 52 arranged opposite to each other. An upper circular plate 54 and a lower circular plate 55, arranged from top to bottom, are positioned between the left arc plate 51 and the right arc plate 52. Connecting plates 53 are fixedly installed at the front and rear ends of the left arc plate 51 and the right arc plate 52 at positions between the upper circular plate 54 and the lower circular plate 55. A bevel gear 56 is rotatably connected to the center of each connecting plate 53 via a rotating rod. Gear teeth 57 that mesh with the corresponding bevel gear 56 are provided at the corresponding edges of the upper circular plate 54 and the lower circular plate 55. Cleaning cotton 513 is fixedly provided at the center of the opposite side of the lower circular plate 55 and the opposite side of the two bevel gears 56. T-shaped blocks 511 are fixedly provided at the center of the top of the opposite side of the left arc plate 51 and the right arc plate 52. Limiting grooves 512 are opened at the positions of the two T-shaped blocks 511 on the outer periphery of the upper circular plate 54, and the two T-shaped blocks 511 are slidably connected to the corresponding limiting grooves 512. A slot 510 is provided through the center of the bottom end of one side of the left arc plate 51. A moving tube 58 is fixedly provided at the center of the bottom of the lower circular plate 55. The bottom end of the moving tube 58 is movably connected to a fixed tube 59 fixedly connected to the base 1 through a bearing.

[0038] Furthermore, the linkage mechanism 6 includes a motor 61 fixedly installed on one side of the mounting platform 2. A rotating shaft 62, which movably passes through the through holes at the upper and lower ends of the mounting platform 2, is fixedly connected to the end of the output shaft of the motor 61. A single-sided cam 63 is fixedly connected to the end of the rotating shaft 62. A connecting rod 64 is fixedly installed at the end of the single-sided cam 63 that is offset from the rotating shaft 62. A transmission rod 67 passes through the slot 510. A traction groove 68 is opened on the side of the bottom of the moving tube 58 facing the slot 510. A connecting block 66 is fixedly installed at the end of the transmission rod 67 near the traction groove 68 and at the end away from the traction groove 68. A ball 65, which is fixedly connected to the connecting rod 64, is rolled and embedded on the side of the mounting platform 2 facing the motor 61. Two parallel straight bars 610 are fixedly installed on the side of the mounting platform 2 away from the motor 61. A trapezoidal block 611 is set between the two straight bars 610. Guide grooves 612 are opened on both the front and rear sides of the trapezoidal block 611. A limiting rod 613 is fixedly embedded on the opposite side of the two straight bars 610 at the position corresponding to the two guide grooves 612. The opposite ends of the two limiting rods 613 are slidably connected to the inside of the guide grooves 612 at the corresponding positions. A double-sided cam 69 is fixedly sleeved on the outside of the rotating shaft 62 at the position corresponding to the trapezoidal block 611.

[0039] It should be noted that the inclined surfaces of trapezoidal block 1 44 and trapezoidal block 2 611 are arranged opposite each other, so that trapezoidal block 2 611 can push trapezoidal block 1 with less effort. The side of trapezoidal block 2 611 away from the inclined surface is set as an arc surface, which can prevent the double cams 69 from being blocked during rotation and unable to rotate. The bottom of the end of the supporting diaphragm tube 8 near the eyepiece 10 is fixed with a push handle 13, which makes it easy to push the supporting diaphragm tube 8 out of the movable sleeve with the push handle 13, thereby exposing the supporting diaphragm 12. There are four cleaning ports 31, which are arranged one-to-one with the cleaning cotton 513 of the upper circular plate 54, the lower circular plate 55 and the two bevel gears 56. The cleaning surface of the cleaning cotton 513 is in close contact with the outer surface of the movable sleeve 7, so as to achieve cleaning of the movable sleeve with the diaphragm installation structure and the hysteroscope. The outer circumference of tube 7 is thoroughly cleaned. The cleaning cotton 513 used is soaked in medical alcohol. The pushing component 48 is aligned with the pushing port 32. Before using this device to install the diaphragm, the supporting diaphragm 12 to be installed is placed at the end of the supporting diaphragm tube 8, and the hysteroscope is fitted inside the supporting diaphragm tube 8. The supporting diaphragm tube 8 is then fitted inside the movable sleeve 7, exposing the hysteroscope 11. Then, the movable sleeve 7, which contains the diaphragm installation structure and the hysteroscope, is inserted into the fixed tube 3, ensuring that the inserted end of the movable sleeve 7 does not enter the cleaning area and is exposed in the pushing area. The position of the device is then adjusted so that the inserted end of the movable sleeve 7 is aligned with the vaginal opening. When starting the diaphragm installation, the device is controlled externally. The starter motor 61 is activated. The motor operates at a slow speed to avoid excessively rapid insertion, which could cause discomfort to the patient or even secondary damage to the uterine cavity. When the motor 61 drives the rotating shaft 62, it drives the single-sided cam 63 and the double-sided cam 69 to rotate synchronously. During this process, as the double-sided cam 69 rotates, it intermittently squeezes the arc surface on the trapezoidal block 611. As the double-sided cam 69 separates from the initial squeezing state, the trapezoidal block 611 gradually moves upward under the cooperation of the limiting rod 613 and the guide groove 612. At this time, because the inclined surfaces of the trapezoidal block 44 and the trapezoidal block 611 are in relative contact, and the top surface of the trapezoidal block 44 is in contact with the bottom surface of the horizontal plate 45, the upward movement of the trapezoidal block 611 pushes the trapezoidal block 611 upward. Trapezoidal block 44 moves to the right along the horizontal plate 45. This movement causes the horizontal bar 42 to move to the right simultaneously, compressing the spring 43. The rightward movement of trapezoidal block 44 also causes the pushing assembly 48 to move to the right, thus pushing the movable sleeve 7 to the right. Once the double-sided cam 69 completely separates from the compression state of trapezoidal block 611 and enters the next compression cycle, the pushing assembly 48 will reset under the restoring force of the spring 43. Then, as the double-sided cam 69 and trapezoidal block 611 compress again, the movable sleeve 7 continues to be pushed forward, thus achieving intermittent pushing of the movable sleeve 7. As the single-sided cam 63 rotates, because the connecting rod 64 and the connecting block 66 are connected by a rolling ball 65, the connecting rod 64 moves in a circular motion along with the single-sided cam 63.While the transmission rod 67 moves up and down along the traction groove 68, it also swings left and right within the groove opening 510, thereby driving the moving tube 58 and the lower circular plate 55 to swing left and right synchronously. Since the upper circular plate 54 and the lower circular plate 55 are engaged with the corresponding bevel gears 56 through the gear teeth 57 at their opposite edges, the upper circular plate 54, under the action of the T-shaped block 511 and the limiting groove 512, swings in the opposite direction to the lower circular plate 55 as the lower circular plate 55 swings left and right. Thus, the cleaning cotton 513 on the upper circular plate 54, the lower circular plate 55, and the two bevel gears 56 is in close contact with the outer surface of the movable sleeve 7 to achieve cleaning of the movable sleeve with the diaphragm installation structure and the hysteroscope. The outer circumference of the cannula 7 is thoroughly cleaned, ensuring that the insertion end of the movable cannula 7 and the exposed hysteroscope 11 are cleaned before entering the vaginal opening. After the insertion end of the movable cannula 7 and the exposed hysteroscope 11 are in the designated position within the uterine cavity, the motor 61 is turned off. Then, the push handle 13 is pushed to expose the support diaphragm 12 to be installed. Subsequently, rotating the push handle 13 drives the support diaphragm tube 8 to rotate, completing the installation of the support diaphragm 12. This device not only allows for real-time cleaning of the surface of the movable cannula 7, which is fitted with the diaphragm installation structure and the hysteroscope, while intermittently moving to the right, thus preventing infection during the procedure, but also allows the hysteroscope to be used in conjunction with the diaphragm installation structure, making it suitable for widespread use.

[0040] Example 2

[0041] Refer to the instruction manual appendix Figure 5 In one embodiment of the present invention, the telescopic rod 49 on the push mechanism 4 includes a first round rod 491 fixedly connected to the U-shaped plate 47. A second round rod 494 is provided at the top of the first round rod 491. A slot 495 is provided at the bottom of the second round rod 494. An insert rod 492 is fixedly provided at the position of the top of the first round rod 491 corresponding to the slot 495. The top end of the insert rod 492 is movably inserted into the slot 495. A third spring 493 is movably sleeved on the part of the insert rod 492 located between the first round rod 491 and the second round rod 494. The bottom of the inner circumference of the slot 495 is... Annular baffles 496 are fixedly provided at the edge of the end and the top edge of the outer peripheral surface of the insertion rod 492. Two sets of limiting strips 498 are fixedly provided at the bottom of the inner peripheral surface of the slot 495, which are symmetrically arranged about the vertical central axis of the round rod 491. Each set has two vertically parallel ones. Two limiting strips 497 are fixedly provided at the top of the outer peripheral surface of the insertion rod 492, which are symmetrically arranged about the vertical central axis of the round rod 491. The two limiting strips 497 are slidably connected to the groove formed between the two limiting strips 498 in the corresponding set.

[0042] It should be noted that spring three 493 is initially in a compressed state, and the length of limit bar two 498 is one-third the length of limit bar one 497. That is, when pressing down on ring two 494, the top surface of limit bar two 498 can be completely below the bottom surface of limit bar one 497. The outer diameter of the annular baffle 496 is equal to the inner diameter of the slot 495. On the one hand, this ensures that after pressing down on the round rod two 494 to the specified depth, the round rod one 491 can be rotated to change the pushing direction of push block 483. On the other hand, it prevents the round rod one 491 and the round rod two 494 from being pressed against spring three 493. Complete separation under restoring force. When using this device to install the supporting diaphragm 12, simply hold the second round rod 494 vertically downward and compress the third spring 493. This will cause the second limiting strip 498 at the bottom of the inner circumference of the slot 495 on the second round rod 494 to move down along the first limiting strip 497 until it separates from the second limiting strip 498. Then, rotate the second round rod 494 so that the pushing component 48 moves in the forward direction toward the insertion end of the movable sleeve 7. Conversely, after use, repeat the above operation to adjust the pushing component 48 in the retraction direction toward the insertion end of the movable sleeve 7. The operation is convenient and quick.

[0043] Example 3

[0044] Refer to the instruction manual appendix Figure 5-7 In one embodiment of the present invention, the pusher assembly 48 on the pusher mechanism 4 includes two vertical ear plates 481 arranged symmetrically about the central axis of the second round rod 494 and fixedly connected to the top surface of the second round rod 494. A fixing rod 482 is fixedly connected to the center position of the opposite side of the two vertical ear plates 481. A pusher block 483 is arranged between the two vertical ear plates 481. Insertion holes 484 are opened on both the front and rear sides of the bottom end of the pusher block 483. The two fixing rods 482 are respectively movably inserted into the corresponding insertion holes 484. An arc-shaped guide hole 485 is provided through one side of the top end of the pusher block 483. A guide rod 486 is movably inserted inside the guide hole 485. One end of the guide rod 486 is fixed with a limit plate 487 and the other end is fixedly connected to the outer peripheral surface of the second round rod 494. A spring 488 is movably sleeved on the part of the outer peripheral surface of the guide rod 486 between the pusher block 483 and the second round rod 494.

[0045] It should be noted that the push block 483 has an arc groove 489 at the middle of the end away from the second round rod 494. The surface of the arc groove 489 is covered with an anti-slip pad, which allows the top surface of the push block 483 to better fit the movable sleeve 7 and prevents relative sliding between the push block 483 and the movable sleeve 7 during intermittent pushing of the movable sleeve 7. The second spring 488 is initially in a compressed state, and the elastic coefficient of the third spring 493 is greater than that of the second spring 488, which ensures that the push block 483 will not push the movable sleeve 7 back during the reset and next round of pushing. In particular, when using this device to install the supporting diaphragm 12. At this time, the top of the push block 483 is facing the forward direction of the insertion end of the movable sleeve 7, and the arc groove 489 on it is in close contact with the outer surface of the movable sleeve 7. As the push block 483 moves to the right, it will push the movable sleeve 7 into the uterine cavity in a synchronized manner. When the push block 483 steps back in one step, since the elastic coefficient of spring three 493 is greater than the elastic coefficient of spring two 488, the push block 483 will compress spring two 488 along the guide rod 486, so that when the push block 483 retracts, it will not drive the movable sleeve 7 to move back, thereby realizing the intermittent forward push of the movable sleeve 7. Conversely, after use, the inserted movable sleeve 7 can be withdrawn according to the above operating principle.

[0046] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

[0047] As a further solution to the above-mentioned solution, a method for identifying secretions from a biodegradable support diaphragm device for preventing intrauterine adhesions is provided.

[0048] S1 places a moisture sensor, an ultrasonic feedback module, a controller, and a signal transceiver module on the supporting diaphragm tube or secretion contact component;

[0049] S2 classifies the humidity of secretions and assigns different levels of secretions and corresponding tissues to the moisture ratio value of the secretions. When the corresponding moisture ratio value is called, the controller directly returns the value of the secretions to be separated.

[0050] S3 emits ultrasound waves onto the secretions, and determines the water content of the tissue or secretions according to a preset ratio based on the return value of the ultrasound waves. Then, it uses the water ratio value in S2 to correspond to the type of secretions or tissues.

[0051] S4 When the secretion type value returned by the ultrasonic feedback module is inconsistent with the secretion type value returned by the water ratio value, the average value of the two water ratio values ​​is taken and the secretion type value is matched a second time.

[0052] In a preferred embodiment,

[0053]

[0054] Where μx and E{x} are used to express the average value of ultrasound echoes when ultrasound is irradiated onto secretions, x represents the echo signal sequence value of ultrasound, T represents the echo time of ultrasound, N represents all sampling points in ultrasound, and n represents one of the echo sampling points in N.

[0055] When the water content of secretions increases, the energy absorbed by the water also increases, causing the echo of the ultrasound to decrease. Conversely, the echo will increase. The echo value of the ultrasound is used to distribute the secretions of different water contents proportionally.

[0056] Further explanation is needed. By emitting waves to the secretions using ultrasound, the water content of the tissue or secretion is determined according to a preset ratio based on the ultrasound return value. Then, the water ratio value in S2 is used to correspond to the secretion or tissue type value. When the secretion type value returned by the ultrasound feedback module is inconsistent with the secretion type value returned by the water ratio value, the two water ratio values ​​are averaged and used for secondary matching of secretion type values. When ultrasound identifies secretions, when the secretion water content increases, the water absorbs more ultrasound energy, causing the ultrasound echo to decrease, and vice versa. The ultrasound echo value is proportionally distributed to secretion types with different water contents, thereby improving the convenience of secretion identification.

[0057] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may change.

The supporting diaphragm tube (8) near the hysteroscope lens (11) is covered with a supporting diaphragm (12). The biodegradable support diaphragm device for preventing intrauterine adhesions is also used for secretion identification, and is performed through the following steps: S1. Place a moisture sensor, an ultrasonic feedback module, a controller, and a signal transceiver module on the supporting diaphragm tube. S2. Classify the humidity of secretions and assign different levels of secretions to the moisture ratio value of secretions. When the corresponding moisture ratio value is called, the secretion type value is returned directly through the controller. S3. The ultrasonic feedback module emits waves to the secretions. Based on the return value of the ultrasonic waves, the water content of the secretions is determined according to a preset ratio. Then, the water content in S2 is used to determine the type of secretions. S4. When the secretion type value returned by the ultrasonic feedback module is inconsistent with the secretion type value returned by the moisture sensor, the average of the two moisture ratio values ​​is used to perform a second matching of the secretion type value.
