Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to a device for resecting submucosal fibroids in conjunction with a hysteroscope. Background Technology

[0002] Submucosal fibroids, a common type of uterine fibroid, mainly grow in the uterine mucosa and often cause symptoms such as excessive menstrual bleeding, prolonged menstrual periods, abdominal pain, and infertility, seriously affecting women's reproductive health and quality of life. In clinical treatment, hysteroscopic surgery has become the mainstream method for treating submucosal fibroids due to its advantages such as being minimally invasive, having a fast postoperative recovery, and causing less damage to the overall structure of the uterus.

[0003] Currently, there are still significant shortcomings in the techniques and instruments used in conjunction with hysteroscopy for the resection of submucosal myomas. From the perspective of the core process of myoma treatment, existing technologies are unable to achieve a coordinated and integrated operation of "clamping-crushing-discharge of debris". Some instruments only have a single clamping or cutting function and lack a stable clamping structure, which makes the myomas easy to shift during the cutting process and increases the risk of damage to normal tissues. Summary of the Invention

[0004] In view of the problem that some existing instruments only have a single clamping or cutting function and lack a stable clamping structure, which makes the fibroids easy to shift during the cutting process and increases the risk of damage to normal tissue, the purpose of this invention is to provide a device for submucosal fibroid resection in conjunction with hysteroscopy.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A device for resecting submucosal fibroids in conjunction with hysteroscopy includes an operating rod with a clamping mechanism fixed by a connecting component. The clamping mechanism includes a cover and a clamping plate installed inside the cover. The clamping plate can be opened and closed to clamp or release the fibroid. A pulverizing component is installed inside the cover to pulverize the fibroid. A suction component is connected to the cover.

[0007] Optionally, the clamping mechanism includes a cover cylinder fixed to the operating rod by a connecting assembly. The cover cylinder has several straight slots, and a movable shaft is slidably installed in each of the straight slots. A clamping plate is fixedly installed on the movable shaft. An adjusting plate is rotatably installed inside the cover cylinder. The adjusting plate has several adjusting grooves that cooperate with the movable shafts. A protrusion is fixedly installed on the adjusting plate. A control rope is fixedly installed on the protrusion. The end of the control rope away from the protrusion passes through the cover cylinder.

[0008] Optionally, a protruding plate is fixedly installed on the adjusting plate, a first spring is fixedly installed on the protruding plate, a limiting plate is fixedly installed inside the cover, and the end of the first spring away from the protruding plate is fixedly connected to the limiting plate.

[0009] Optionally, the operating lever is provided with a locking assembly that cooperates with the control rope. The locking assembly includes a locking platform fixedly installed on the operating lever. The locking platform has an installation cavity. A pair of rotating shafts are rotatably installed in the installation cavity. An arc-shaped locking plate is fixedly installed on each rotating shaft. An anti-slip groove is provided at the end of the arc-shaped locking plate that contacts the control rope. A spring strip is fixedly installed on each arc-shaped locking plate. The other end of the spring strip is fixedly connected to the inner wall of the installation cavity. The connecting rope passes through the installation cavity and is located between the pair of arc-shaped locking plates.

[0010] Optionally, a second spring is fixedly installed inside the mounting cavity, and a release sleeve is fixedly installed at the other end of the second spring. The control rope passes through the release sleeve, and through holes are provided on both sides of the release sleeve for the arc-shaped locking plate to abut against the control rope.

[0011] Optionally, the crushing assembly includes a set of first motors, on the output shaft of which a set of staggered blades are fixedly mounted.

[0012] Optionally, the rotating assembly includes a second motor fixedly mounted on the cover, the output shaft of the second motor passing through the cover and fixedly mounted on a mounting plate, and the first motor fixedly mounted on the mounting plate.

[0013] Optionally, the suction assembly includes a pair of suction tubes fixedly installed on the cover, an integrated box fixedly installed on the suction tubes, an air pipe fixedly installed on the integrated box, and the end of the air pipe away from the integrated box being connected to a suction air source.

[0014] Optionally, a filter plate is fixedly installed inside the integrated box, and a wiping plate that cooperates with the filter plate is slidably installed on the integrated box.

[0015] Optionally, the connecting assembly includes a mounting block fixedly mounted on the cover, an insert plate fixedly mounted on the mounting block, a slot provided on the operating rod, a limit post slidably mounted inside the insert plate, a third spring fixedly mounted on the limit post, one end of the third spring away from the limit post being fixedly connected to the inner wall of the insert plate, and a limit hole provided on the operating rod that cooperates with the limit post.

[0016] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0017] In the above procedure, during the submucosal fibroid resection, the doctor first holds the operating lever and, guided by the visualization of the hysteroscope, sends the end of the device with the clamping mechanism to the fibroid location. Then, the clamping mechanism is used to firmly clamp the fibroid, ensuring that the fibroid will not move randomly during subsequent operations. After the fibroid is clamped, the rotating component is activated, which drives the crushing component to move inside the sleeve of the clamping mechanism, enabling the crushing component to break up the clamped fibroid.

[0018] During and after the pulverization process, the suction component continues to work, generating negative pressure suction to promptly aspirate and remove the pulverized fibroid fragments from the body. This process achieves coordinated operation of fibroid clamping, pulverization, and fragment removal, avoiding the retention of fibroid fragments in the uterine cavity, reducing the risk of surgical complications, and improving the convenience and accuracy of the surgical procedure.

It should also be noted that, to make the embodiments more comprehensive, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some well-known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0038] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0040] It is understood that the meanings of “on”, “above”, and “above” in this invention should be interpreted in the broadest manner, such that “on” means not only “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” means not only “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0041] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings.

[0042] like Figures 1 to 8 As shown, this embodiment of the invention provides a device for submucosal myoma resection in conjunction with hysteroscopy, including an operating rod 10. The operating rod 10 is equipped with a clamping mechanism 20 fixed by a connecting component 70. The clamping mechanism 20 is used to clamp the myoma and, in conjunction with a crushing component 40, crush it. A rotating component 50 is disposed within a sleeve 21 in the clamping mechanism 20. The rotating component 50 is used to drive the crushing component 40 to rotate and crush within the sleeve 21. A suction component 60 is disposed on the clamping mechanism 20 and the operating rod 10, and is used to suction out the crushed myoma.

[0043] During submucosal fibroid resection, the surgeon first holds the operating lever 10 and, guided by hysteroscopy, guides the device with the clamping mechanism 20 to the fibroid location. The clamping mechanism 20 then securely clamps the fibroid, ensuring it won't shift during subsequent procedures. Once clamped, the rotating component 50 is activated, driving the pulverizing component 40 within the sleeve 21 of the clamping mechanism 20 to break up the clamped fibroid. During and after pulverization, the suction component 60 continuously operates, generating negative pressure to promptly remove the pulverized fibroid fragments. This process achieves coordinated clamping, pulverization, and fragment removal of the fibroid, preventing fragments from remaining in the uterine cavity, reducing the risk of surgical complications, and improving the convenience and accuracy of the procedure.

[0044] like Figure 2 and Figure 3 As shown, the clamping mechanism 20 includes a cover 21 fixed to the operating rod 10 by a connecting assembly 70. The cover 21 has several straight slots 22, and a movable shaft 23 is slidably installed in each of the straight slots 22. A clamping plate 24 is fixedly installed on the movable shaft 23. An adjusting plate 25 is rotatably installed inside the cover 21. The adjusting plate 25 has several adjusting grooves 211 that cooperate with the movable shaft 23. A protrusion 26 is fixedly installed on the adjusting plate 25. A control rope 27 is fixedly installed on the protrusion 26. The end of the control rope 27 away from the protrusion 26 passes through the cover 21.

[0045] When the clamping mechanism 20 is needed to clamp the fibroid, the doctor pulls the control rope 27. The control rope 27 drives the fixedly connected protrusion 26 to move. The protrusion 26 then drives the adjusting plate 25 to rotate inside the cover 21. Since the adjusting plate 25 has an adjusting groove 211 that cooperates with the movable shaft 23, when the adjusting plate 25 rotates, the adjusting groove 211 will exert a force on the movable shaft 23, forcing the movable shaft 23 to slide in the straight groove 22 on the cover 21. As the movable shaft 23 slides, it will drive the clamping plate 2 fixed to it. 4. Synchronous movement: Several clamping plates 24 move closer to each other to clamp the fibroid. The straight groove 22 guides the sliding of the movable shaft 23, ensuring the stability of the movement direction of the clamping plates 24 and preventing deviation that could lead to insecure clamping. By controlling the tension of the rope 27, the rotation angle of the adjusting disc 25 can be adjusted, thereby controlling the opening and closing degree of the clamping plates 24 to adapt to fibroids of different sizes, improving the versatility and clamping effect of the clamping mechanism 20, and ensuring that the subsequent crushing component 40 can stably crush the fibroid.

[0046] For example Figure 2As shown, a protruding plate 28 is fixedly installed on the adjusting plate 25, a first spring 29 is fixedly installed on the protruding plate 28, a limiting plate 210 is fixedly installed inside the cover 21, and the end of the first spring 29 away from the protruding plate 28 is fixedly connected to the limiting plate 210.

[0047] During the procedure, as the doctor pulls the control rope 27 to rotate the adjusting plate 25 and clamp the fibroid with the splint 24, the protruding plate 28 on the adjusting plate 25 moves along with it. At this time, the protruding plate 28 compresses the first spring 29, causing it to store elastic potential energy due to deformation. The limiting plate 210 provides a fixed support point for the first spring 29, ensuring that it can stably generate elastic force. When the surgery is complete and the splint 24 needs to be loosened, the doctor releases the control rope 27, at which point the first spring 29 releases its stored elastic potential energy. Yes, it can push the convex plate 28 to move, and the convex plate 28 drives the adjusting plate 25 to rotate in the opposite direction. The adjusting plate 25, through the cooperation of the adjusting groove 211 and the movable shaft 23, makes the movable shaft 23 slide in the opposite direction in the straight groove 22, thereby driving the clamps 24 to move away from each other, realizing the automatic reset of the clamps 24. The doctor does not need to manually operate to reset the clamps 24, which simplifies the surgical procedure, saves surgical time, and at the same time ensures the stability and consistency of the reset of the clamps 24, avoiding device failure or unnecessary damage to the uterine cavity tissue due to improper manual reset.

[0048] like Figure 5 and Figure 6 As shown, the operating lever 10 is provided with a locking assembly 30 that cooperates with the control rope 27. The locking assembly 30 includes a locking platform 31 fixedly installed on the operating lever 10. The locking platform 31 has an installation cavity 32. A pair of rotating shafts 33 are rotatably installed in the installation cavity 32. An arc-shaped locking plate 34 is fixedly installed on each of the rotating shafts 33. An anti-slip groove 241 is provided at the end of the arc-shaped locking plate 34 that contacts the control rope 27. One end of a spring strip 35 is fixedly installed on each of the arc-shaped locking plates 34. The other end of the spring strip 35 is fixedly connected to the inner wall of the installation cavity 32. The connecting rope passes through the installation cavity 32 and is located between the pair of arc-shaped locking plates 34.

[0049] After the doctor pulls the control rope 27 to clamp the fibroid with the splint 24, the locking assembly 30 activates to prevent the control rope 27 from loosening and reducing the clamping force of the splint 24 on the fibroid. During the pulling of the control rope 27, it exerts a force on the arc-shaped locking plate 34. Since the arc-shaped locking plate 34 is rotatably mounted in the mounting cavity 32 of the locking platform 31 via the pivot 33, and a spring clip 35 is fixed to the arc-shaped locking plate 34 with its other end fixed to the inner wall of the mounting cavity 32, the arc-shaped locking plate 34 rotates slightly around the pivot 33 when the control rope 27 is pulled, causing the spring clip 35 to deform. When the control rope 27 is pulled to the appropriate position, i.e., the splint 24 clamps the fibroid... After the fibroid is securely clamped, the elastic force of the spring clip 35 will push the arc-shaped locking plate 34 to return to its original position, making the arc-shaped locking plate 34 in close contact with the control rope 27. The anti-slip groove on the arc-shaped locking plate 34 can increase the friction between it and the control rope 27, thereby locking the control rope 27 in its current position and preventing the control rope 27 from moving during the operation due to external force or its own loosening. This ensures the stability of the clamping of the fibroid by the clamping plate 24, so that the fibroid will not move due to loose clamping when the pulverizing component 40 pulverizes the fibroid, ensuring that the pulverizing operation can be carried out smoothly. At the same time, it also reduces the burden on the doctor to continuously pull the control rope 27 during the operation, improving the doctor's comfort and focus during the operation.

[0050] For example Figure 5 As shown, one end of the second spring 37 is fixedly installed in the mounting cavity 32, and the other end of the second spring 37 is fixedly installed with a release sleeve 36. The control rope 27 passes through the release sleeve 36. The release sleeve 36 has through holes 361 on both sides for the arc-shaped locking plate 34 to abut against the control rope 27.

[0051] When it is necessary to release the locking state of the locking assembly 30 on the control rope 27, the doctor pulls the release sleeve 36 into the installation cavity 32. The release sleeve 36 will exert a tensile force on the second spring 37, causing the second spring 37 to deform. During the movement, the release sleeve 36 will push the arc-shaped locking plate 34 to rotate around the pivot 33, causing the arc-shaped locking plate 34 to separate from the control rope 27. At this time, the control rope 27 is no longer subject to the locking force of the arc-shaped locking plate 34, and the doctor can pull or loosen the control rope 27 as needed to adjust the opening and closing state of the clamp 24. After the doctor releases the release sleeve 36, the second spring 37 releases its elastic potential energy, the release sleeve 36 returns to its original position, and the force exerted by the release sleeve 36 on the arc-shaped locking plate 34 disappears. Under the elastic force of the spring bar 35, the arc-shaped locking plate 34 returns to the state of contact with the control rope 27. If the position of the control rope 27 is appropriate at this time, it can be locked again, making the unlocking operation simple and convenient, without complicated operation steps, ensuring the smoothness of the surgical procedure, and at the same time, it can accurately control the timing of the lock release, avoiding misoperation that would cause the control rope 27 to loosen when the lock does not need to be released.

[0052] like Figure 4 As shown, the crushing component 40 includes a set of first motors 41, and a set of staggered blades 42 are fixedly mounted on the output shaft of the first motors 41.

[0053] Once the clamping mechanism 20 has secured the fibroid, the first motor 41 in the crushing assembly 40 is activated. The output shaft of the first motor 41 begins to rotate, driving a set of blades 42 fixed on the output shaft to rotate at high speed. Since the blades 42 are arranged in an alternating manner, the cutting area formed between adjacent blades 42 can more comprehensively cover the fibroid during rotation, performing multi-angle and multi-layer cutting and crushing of the fibroid, avoiding crushing dead angles, improving the crushing efficiency and effect of the fibroid, and enabling the fibroid to be crushed into smaller fragments, which are then easily sucked out by the subsequent suction assembly 60.

[0054] For example Figure 4 As shown, the rotating assembly 50 includes a second motor 51 fixedly mounted on the cover cylinder 21. The output shaft of the second motor 51 passes through the cover cylinder 21 and is fixedly mounted on a mounting plate 52. The first motor 41 is fixedly mounted on the mounting plate 52.

[0055] While the crushing component 40 is working, the second motor 51 in the rotating component 50 is started. The output shaft of the second motor 51 begins to rotate. Since the output shaft of the second motor 51 passes through the cover cylinder 21 and is fixedly mounted on the mounting plate 52, and the first motor 41 is fixed on the mounting plate 52, the rotation of the output shaft of the second motor 51 will drive the mounting plate 52 to rotate around the axis of the output shaft of the second motor 51. The mounting plate 52 then drives the first motor 41 and the blade 42 fixed on the output shaft of the first motor 41 to rotate together inside the cover cylinder 21. This rotational motion allows the blade 42 to perform circumferential motion around the fibroid while it is cutting at high speed, thus expanding the crushing range of the blade 42. This allows for more thorough crushing of the fibroids clamped in the cover cylinder 21, avoiding the situation where some fibroids cannot be crushed due to the blade 42 being fixed in place. The second motor 51 can control the rotation speed of the mounting plate 52 by adjusting its rotation speed, thereby adjusting the overall crushing rhythm of the blade 42 according to the actual situation such as the size and hardness of the fibroid, further improving the crushing effect and efficiency.

[0056] like Figure 1 and Figure 7 As shown, the suction assembly 60 includes a pair of suction tubes 61 fixedly installed on the cover 21. An integrated box 62 is fixedly installed on the suction tubes 61. An air tube 63 is fixedly installed on the integrated box 62. The end of the air tube 63 away from the integrated box 62 is connected to the suction air source.

[0057] While the pulverizing component 40 is pulverizing the fibroids, the suction air source connected to the trachea 63 in the suction component 60 is simultaneously activated. The suction air source generates negative pressure in the integrated box 62 through the trachea 63. The integrated box 62 then forms a negative pressure environment in the cover 21 through the suction tube 61 fixedly connected to it. Since the suction tube 61 is fixedly installed on the cover 21 and is set in pairs, it can suction the pulverized fibroid fragments from different positions in the cover 21, expanding the suction range and ensuring that the fibroid fragments generated in the cover 21 can be fully sucked into the suction tube 61. The fibroid fragments enter the integrated box 62 through the suction tube 61, ensuring that the fibroid fragments do not accumulate in the cover 21 during the pulverizing process, preventing fragments from clogging the device or remaining in the uterine cavity and causing complications such as infection.

[0058] For example Figure 7 As shown, a filter plate 64 is fixedly installed inside the integrated box 62, and a wiping plate 65 that cooperates with the filter plate 64 is slidably installed on the integrated box 62.

[0059] During the aspiration of fibroid fragments by the aspiration assembly 60, after the fibroid fragments enter the integrated box 62 through the aspiration tube 61, they first pass through the filter plate 64 fixedly installed inside the integrated box 62. The filter plate 64 can filter the fibroid fragments, intercepting larger particles on the side of the filter plate 64 facing the aspiration tube 61, preventing larger particles from entering the trachea 63 and avoiding blockage of the trachea 63, thus ensuring the continuous unobstructed aspiration channel. As the aspiration operation proceeds, a certain amount of fibroid fragments will gradually accumulate on the filter plate 64. If not cleaned in time, it may affect the filtration effect and aspiration efficiency of the filter plate 64. At this time, the doctor can push the wiping plate 65 slidably installed on the integrated box 62. During the sliding process, the wiping plate 65 will contact the surface of the filter plate 64 to wipe and clean the fibroid fragments accumulated on the filter plate 64, removing the fragments from the surface of the filter plate 64 and restoring the filter plate 64 to good filtration performance.

[0060] like Figure 7 As shown, the connecting assembly 70 includes a mounting block 71 fixedly mounted on the cover 21, an insert plate 72 fixedly mounted on the mounting block 71, a slot 73 provided on the operating rod 10, a limiting post 75 slidably mounted inside the insert plate 72, a third spring 74 fixedly mounted on the limiting post 75, one end of the third spring 74 away from the limiting post 75 being fixedly connected to the inner wall of the insert plate 72, and a limiting hole 76 provided on the operating rod 10 to cooperate with the limiting post 75;

[0061] When assembling the clamping mechanism 20 and the operating rod 10, the insert plate 72 fixed on the mounting block 71 on the cover 21 is aligned with the slot 73 opened on the operating rod 10, and the insert plate 72 is inserted into the slot 73. During the insertion of the insert plate 72, the inner wall of the slot 73 of the operating rod 10 will exert a squeezing force on the limiting post 75 slidably installed in the insert plate 72, causing the limiting post 75 to slide into the insert plate 72. At the same time, the limiting post 75 will compress the third spring 74 fixedly connected to it. The third spring 74 will deform and store elastic potential energy. When the insert plate 72 is fully inserted into the slot 73, the limiting post 75 in the insert plate 72 will engage with the operating rod 10. When the limiting holes 76 are aligned, the third spring 74 releases its elastic potential energy, pushing the limiting post 75 to slide outwards towards the insert plate 72, so that the limiting post 75 is inserted into the limiting hole 76, thereby fixing the insert plate 72 and the operating rod 10 together. This achieves the assembly and fixation of the clamping mechanism 20 and the operating rod 10. The connection component 70 enables quick assembly and disassembly between the clamping mechanism 20 and the operating rod 10, facilitating the maintenance, upkeep, and component replacement of the device. At the same time, the cooperation between the limiting post 75 and the third spring 74 ensures the firmness of the connection, preventing the clamping mechanism 20 from separating from the operating rod 10 during the operation, thus ensuring surgical safety.

[0062] The specific workflow of the technical solution provided by this invention is as follows:

[0063] When performing submucosal myoma resection surgery in conjunction with hysteroscopy, the clamping mechanism 20 and the operating rod 10 are first assembled through the connecting component 70. The insert plate 72 of the mounting block 71 on the cover 21 is inserted into the slot 73 of the operating rod 10. The inner wall of the slot 73 squeezes the limiting post 75 to compress the third spring 74. After the insert plate 72 is inserted into place, the third spring 74 returns to its original position and pushes the limiting post 75 into the limiting hole 76, so that the two are firmly connected.

[0064] The doctor holds the operating lever 10 and, guided by hysteroscopy, guides one end of the device with the clamping mechanism 20 to the fibroid. Pulling the control rope 27 causes the protrusion 26 to rotate the adjusting disc 25 within the casing 21. The adjusting groove 211 drives the movable shaft 23 to slide along the straight groove 22, allowing the clamping plate 24 to approach and clamp the fibroid. During this process, the protrusion 28 stretches the first spring 29. Once the clamping plate 24 is securely clamped, the spring bar 35 of the locking assembly 30 pushes the arc-shaped locking plate 34 to rotate around the rotating shaft 33. Its anti-slip groove makes close contact with the control rope 27, locking the control rope 27 within the mounting cavity 32 of the locking platform 31 to prevent loosening.

[0065] Then, the crushing component 40 and the rotating component 50 are activated. The first motor 41 drives the staggered blades 42 to rotate at high speed to cut the fibroids. The second motor 51 drives the mounting plate 52 on the output shaft to rotate. The mounting plate 52 carries the first motor 41 and the blades 42 to rotate around the output shaft of the second motor 51 inside the cover 21, expanding the crushing range and achieving thorough crushing of the fibroids.

[0066] Simultaneously, the suction assembly 60 is activated: the suction air source generates negative pressure in the integrated box 62 through the air pipe 63, and the negative pressure acts on the hood 21 through the suction pipe 61, sucking the crushed fibroid fragments into the suction pipe 61. After the fragments enter the integrated box 62, the filter plate 64 intercepts larger particles to prevent blockage of the air pipe 63. If the filter plate 64 accumulates fragments, the sliding wipe plate 65 can be used to clean it. The fragments are finally discharged from the device through the air pipe 63.

[0067] After the surgery, pulling the release sleeve 36 stretches the second spring 37, and the release sleeve 36 pushes the arc-shaped locking plate 34 to separate from the control rope 27. The first spring 29 resets and drives the adjustment plate 25 to rotate in the opposite direction, so that the splint 24 releases the fibroid.

[0068] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
