Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an intrauterine suture kit for uterine scar diverticulum. Background Technology

[0002] For patients with symptomatic uterine scar diverticula, the main surgical treatment methods currently include: 1. Hysteroscopic uterine scar diverticulum repair; 2. Combined hysteroscopic and laparoscopic folding and suturing of the uterine scar; 3. Vaginal, open, and laparoscopic uterine scar diverticulum resection and repair. Hysteroscopic uterine scar diverticulum repair is minimally invasive, mainly involving smoothing the slope of the diverticulum outflow tract to allow menstrual blood to flow out, improving symptoms of prolonged menstrual bleeding, but the success rate is less than 70%. Uterine scar folding and suturing requires combined hysteroscopic and laparoscopic surgery, which involves opening the vesicoperitoneal reflection and folding the thin anterior wall of the diverticulum to reduce its size. This procedure is highly invasive and costly for patients. Uterine scar diverticulum resection and repair also requires opening the vesicoperitoneal reflection, removing the diverticulum, and then suturing and repairing it. This procedure is highly invasive, has a long healing time, and is costly. Currently, there is no device for intrauterine suturing in this type of patient. Therefore, this case study was conducted to further investigate this issue. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an intrauterine suture kit for uterine scar diverticulum that can be operated through natural cavities such as the vagina and uterine cavity, achieve intrauterine suturing and treat scar diverticulum, and has the effects of minimal surgical trauma, low patient cost and more definite treatment effect.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an intrauterine suture kit for uterine scar diverticulum, including a puncture suture, a first puncture device, a second puncture device, and a puncture needle. One end of the puncture suture is fixed with a retaining ring. One end face of the first puncture device is provided with a groove for the retaining ring of the puncture suture to fit over it. The puncture needle is arranged side by side at one end of the second puncture device, and one end of the needle is connected to the second puncture device for opening and closing via a linkage mechanism. The other end of the second puncture device is provided with an angle adjustment mechanism for adjusting the opening and closing angle between the puncture needle and the second puncture device. The other end of the puncture needle is provided with a hook groove for hooking the retaining ring of the puncture suture.

[0005] Furthermore, the second puncture device has a cavity extending through both ends. On one outer surface of the second puncture device, there is a strip-shaped slot extending through one end and communicating with the cavity, allowing the puncture needle and linkage mechanism to pass through. When the puncture needle is adjusted from the open position of the puncture state to the closed position of the tightened state, it passes through the strip-shaped slot and enters the cavity.

[0006] Furthermore, the linkage mechanism includes a first link, a second link, a third link, and a sliding block. The first link and the second link are arranged crosswise and hinged to each other. One end of the first link is hinged to the cavity of the second puncture device, and the other end of the first link is hinged to one end of the third link. The other end of the third link is hinged to the puncture needle. One end of the second link is hinged to the sliding block, and the other end of the second link is hinged to one end of the puncture needle. The sliding block is located in the cavity of the second puncture device and is slidably connected to it. The angle adjustment mechanism is used to drive the sliding block to slide along the length direction of the second puncture device.

[0007] Furthermore, the second link, the puncture needle, the third link, and the first link are arranged sequentially from one side of the second puncture device to the opposite side, and the puncture needle is provided with a notch to avoid the first hinge axis between the first link and the second link.

[0008] Furthermore, two symmetrical inner surfaces inside the cavity of the second puncture device are provided with strip-shaped grooves. The strip-shaped grooves are arranged along the length of the second puncture device and extend through one end. The sliding block is adapted to the strip-shaped grooves, and the two ends of the sliding block are respectively embedded in the two strip-shaped grooves.

[0009] Furthermore, the angle adjustment mechanism includes an adjustment rod and an adjustment knob. The adjustment rod passes through the cavity of the second puncture device. One end of the adjustment rod is fixedly connected to the sliding block, and the other end of the adjustment rod passes through the cavity of the second puncture device and is threadedly connected to the adjustment knob. The adjustment knob is rotatably connected to the other end face of the second puncture device.

[0010] Furthermore, an annular protrusion is fixedly provided on the other end face of the second puncture device, and a rotating hole is provided on one end face of the adjusting knob. The rotating hole of the adjusting knob is sleeved on the outside of the annular protrusion and is rotatably connected to the annular protrusion through a bearing.

[0011] Furthermore, the adjusting knob has an internal threaded hole, and the other end of the adjusting rod has an external threaded section on its outer circumference that matches the internal threaded hole.

[0012] Furthermore, the length of both the first and second puncture devices is greater than 25cm, the outer diameter of the first puncture device is no greater than 2mm, the outer diameter of the second puncture device is no greater than 3mm, and the puncture length of the puncture needle is 15-20mm.

[0013] Furthermore, the outer surface of the first puncture device is provided with a first scale along its length, and the outer surface of the second puncture device is provided with a second scale along its length.

[0014] As described above, the intrauterine suture kit for uterine scar diverticulum provided by this invention has the following beneficial effects: In clinical use, under hysteroscopic visualization and with the uterus distended, the fixing loop of the puncture suture is first placed in the groove at one end of the first puncture device. Then, the first puncture device, with the puncture suture attached, is inserted into the uterine cavity along the vagina and the cervix. The first puncture device then inserts the fixing loop of the puncture suture approximately 1 cm below the scar diverticulum and into the scar diverticulum. Finally, the first puncture device is withdrawn from the uterine cavity. The puncture suture loop is left inside the scar diverticulum. The puncture needle on the second puncture device is then adjusted to the closed position using the angle adjustment mechanism. Next, the second puncture device, along with the puncture needle, is inserted into the uterine cavity through the vagina and cervix. The puncture needle is then opened outwards again using the angle adjustment mechanism and adjusted to the open position for puncture. The angle between the puncture needle and the second puncture device is adjusted to a suitable opening angle. Finally, the second puncture device inserts the puncture needle approximately 1 cm above the scar diverticulum. The needle is inserted into the scar diverticulum, and the suture loop is hooked onto the groove of the puncture needle. The needle is then retracted back into the uterine cavity. The angle adjustment mechanism is used to retract the needle inward and adjust it to the closed position. Then, the second puncture device is withdrawn from the uterine cavity. After the second puncture device is withdrawn, the end of the suture with the loop is brought out of the uterine cavity. At this point, both ends of the suture are outside the uterine cavity. The two ends of the suture left outside the uterine cavity are then tied together and tightened into the scar diverticulum using a knot pusher to close the scar diverticulum. The upper and lower ends of the uterine cavity are tightened to achieve the effect of intrauterine suturing. By closing the scar diverticulum within the uterine cavity, menstrual blood is prevented from remaining in the diverticulum and causing spotting after menstruation. This intrauterine suturing kit is operated through natural cavities such as the vagina and uterine cavity, achieving the effect of treating scar diverticula with minimal surgical trauma. While ensuring the effect, it avoids causing major trauma to the patient. At the same time, the cost to the patient is low, and the effect of closing the scar diverticulum within the uterine cavity is more certain than traditional surgical treatment. Moreover, it can be performed on an outpatient basis. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below through specific embodiments.

[0025] like Figures 1 to 8 As shown, the intrauterine suture kit of the present invention includes a puncture suture 1, a first puncture device 2, a second puncture device 3, and a puncture needle 4. One end of the puncture suture 1 is fixedly provided with a retaining ring 11. One end face of the first puncture device 2 is provided with a groove 21 for the retaining ring 11 of the puncture suture 1 to be fitted. The puncture needle 4 is arranged side by side at one end of the second puncture device 3, and one end of the needle 4 is connected to the second puncture device 3 through a connecting rod mechanism 5. The other end of the second puncture device 3 is provided with an angle adjustment mechanism 6 for adjusting the opening and closing angle between the puncture needle 4 and the second puncture device 3. The other end of the puncture needle 4 is provided with a hook groove 41 for hooking the retaining ring 11 of the puncture suture 1.

[0026] In clinical use, under hysteroscopic visualization and with the uterus distended, the fixing loop 11 of the puncture suture 1 is first placed into the groove 21 at one end of the first puncture device 2. Then, the first puncture device 2, with the puncture suture 1 attached, is inserted into the uterine cavity 81 of the uterus 8 along the vagina and the cervical opening. The first puncture device 2 inserts the fixing loop 11 of the puncture suture 1 approximately 1 cm below the scar diverticulum 82 and into the scar diverticulum 82. Then, the first puncture device 2 is withdrawn from the uterine cavity 81, leaving the fixing loop of the puncture suture 1 in the scar diverticulum 82. Then, the second puncture device 3 is inserted... The puncture needle 4 is adjusted to the closed position of the tightened state by the angle adjustment mechanism 6. Then, the second puncture device 3, along with the puncture needle 4, is inserted into the uterine cavity 81 through the vagina and the cervical opening of the uterus 8. The puncture needle 4 is then opened outward again by the angle adjustment mechanism 6 and adjusted to the open position of the puncture state. The puncture needle 4 and the second puncture device 3 are adjusted to a suitable opening and closing angle. Then, the second puncture device 3 inserts the puncture needle 4 into the scar diverticulum 82 from about 1 cm above it, and then through the groove of the puncture needle 4. 41. Hook the fixing loop 11 of the puncture suture 1, and then allow the puncture needle 4 to retract back into the uterine cavity 81 along the original path. The angle adjustment mechanism 6 then retracts the puncture needle 4 inward and adjusts it to the closed position of the tightened state. Then, the second puncture device 3 is withdrawn from the uterine cavity 81. After the second puncture device 3 is withdrawn from the uterine cavity 81, one end of the puncture suture 1 with the fixing loop 11 can be brought out of the uterine cavity 81. At this time, both ends of the puncture suture 1 are outside the uterine cavity 81. The two ends of the puncture suture 1 remaining outside the uterine cavity 81 are then tied together and tightened to the scar using a knot pusher. The scar diverticulum 82 is tightened at both ends to achieve the effect of suturing within the uterine cavity 81. By closing the scar diverticulum 82 within the uterine cavity 81, menstrual blood is prevented from remaining in the scar diverticulum 82, thus avoiding postmenstrual spotting. This intrauterine cavity suturing kit is operated through natural cavities such as the vagina and uterine cavity 81, achieving the effect of treating the scar diverticulum 82 with minimal surgical trauma. While ensuring the effect, it avoids causing major trauma to the patient, and the cost to the patient is low. Moreover, by closing the scar diverticulum 82 within the uterine cavity 81, the effect is more certain than traditional surgical treatment, and it can be performed on an outpatient basis.

[0027] In addition, the second puncture device 3 has a cavity 31 extending through both ends. On one side of the outer surface of the second puncture device 3, there is a strip-shaped slot 32 extending through one end and communicating with the cavity 31, allowing the puncture needle 4 and the connecting rod mechanism 5 to pass through. When the puncture needle 4 is adjusted from the open position of the puncture state to the closed position of the tightened state, it passes through the strip-shaped slot 32 and enters the cavity 31. Furthermore, a sealing block 36 is fixedly provided at one end of the opening of the second puncture device 3.

[0028] The linkage mechanism 5 includes a first link 51, a second link 52, a third link 53, and a sliding block 54. The first link 51 and the second link 52 are arranged crosswise and hinged together. Correspondingly, the first link 51 and the second link 52 are hinged through a first hinge shaft 551. One end of the first link 51 is hinged to the cavity 31 of the second puncture device 3. Correspondingly, the first link 51 and the second puncture device 3 are hinged through a second hinge shaft 552. The other end of the first link 51 is hinged to one end of the third link 53. Correspondingly, the first link 51 and the third link 53 are hinged through a third hinge shaft 553. The other end of the third link 54 is hinged to... The puncture needle 4 is hinged to the first connecting rod 53. Correspondingly, the third connecting rod 53 is hinged to the puncture needle 4 via a fourth hinge shaft 554. One end of the second connecting rod 52 is hinged to the sliding block 54. Correspondingly, the second connecting rod 52 and the sliding block 54 are hinged via a fifth hinge shaft 555. The other end of the second connecting rod 52 is hinged to one end of the puncture needle 4. Correspondingly, the second connecting rod 52 and the puncture needle 4 are hinged via a sixth hinge shaft 556. The sliding block 54 is located within the cavity 31 of the second puncture device 3 and is slidably connected to it. Furthermore, the center distance between the first hinge shaft 551 and the third hinge shaft 553, and the center distance between the fourth hinge shaft 554 and the sixth hinge shaft 556 are... The center distances between the first hinge shaft 551 and the sixth hinge shaft 556 are consistent, as are the center distances between the third hinge shaft 553 and the fourth hinge shaft 554. This allows the first connecting rod 51, the second connecting rod 52, the third connecting rod 53, and the puncture needle 4 to form a parallel four-bar linkage structure. The center distance between the first hinge shaft 551 and the sixth hinge shaft 556 is less than the center distance between the first hinge shaft 551 and the second hinge shaft 552, and the center distance between the first hinge shaft 551 and the third hinge shaft 553 is less than the center distance between the first hinge shaft 551 and the fifth hinge shaft 555. Additionally, the angle adjustment mechanism 6 is used to... The sliding block 54 slides along the length of the second puncture device 3. When the angle adjustment mechanism 6 drives the sliding block 54 to slide closer to the end of the second puncture device 3 and reduces the center distance between the second hinge shaft 552 and the fifth hinge shaft 555, the linkage mechanism 5 can be driven to unfold outward, thereby driving the puncture needle 4 to unfold outward to the open position of the puncture state. When the angle adjustment mechanism 6 drives the sliding block 54 to slide away from the end of the second puncture device 3 and increases the center distance between the second hinge shaft 552 and the fifth hinge shaft 555, the linkage mechanism 5 can be driven to retract inward, thereby driving the puncture needle 4 to retract inward to the closed position of the tightened state.

[0029] Correspondingly, the second connecting rod 52, the puncture needle 4, the third connecting rod 53, and the first connecting rod 51 are arranged sequentially from one side of the second puncture device 3 to the opposite side. The puncture needle 4 is provided with a notch 42 for avoiding the first hinge shaft 551 between the first connecting rod 51 and the second connecting rod 52, so as to avoid the puncture needle 4 interfering with the retraction of the connecting rod mechanism 5, thereby effectively ensuring that the puncture needle 4 can be smoothly retracted and switched to the closed position of the tightened state.

[0030] The cavity 31 of the second puncture device 3 has two symmetrical inner surfaces with strip grooves 33. The strip grooves 33 are arranged along the length of the second puncture device 3 and extend through one end. The sliding block 54 is adapted to the strip grooves 33. The two ends of the sliding block 54 are respectively embedded in the two strip grooves 33, which can guide the sliding of the sliding block 54 and realize the sliding cooperation between the sliding block 54 and the second puncture device 3, effectively ensuring the smoothness and stability of the sliding block 54 when sliding.

[0031] The angle adjustment mechanism 6 includes an adjustment rod 61 and an adjustment knob 62. The adjustment rod 61 passes through the cavity 31 of the second puncture device 3. One end of the adjustment rod 61 is fixedly connected to the sliding block 54, and the other end of the adjustment rod 61 passes through the cavity 31 of the second puncture device 3 and is threadedly connected to the adjustment knob 62. The adjustment knob 62 is rotatably connected to the other end face of the second puncture device 3. Since the adjustment position of the adjustment knob 62 is relatively constant, through the threaded transmission between the adjustment rod 61 and the adjustment knob 62, when the adjustment knob 62 is rotated, the adjustment rod 61 can move relative to the adjustment knob 62, thereby driving the sliding block 54 to slide along the strip groove 33 of the second puncture device 3. Through the transmission of the linkage mechanism 5, the opening and closing angle of the puncture needle 4 is adjusted. When the adjustment knob 62 is stopped from being rotated, the adjustment rod 61 will also be in a stationary state to ensure that the puncture needle 4 is stably in the corresponding opening and closing angle.

[0032] Correspondingly, an annular protrusion 35 is fixedly provided on the other end face of the second puncture device 3, and a rotating hole is provided on one end face of the adjustment knob 62. The rotating hole of the adjustment knob 62 is sleeved on the outside of the annular protrusion 35 and is rotatably connected to the annular protrusion 35 through the bearing 7, thereby facilitating the rotational connection between the adjustment knob 62 and the second puncture device 3.

[0033] Correspondingly, the adjusting knob 62 is provided with an internal threaded hole, and the other end of the adjusting rod 61 is provided with an external threaded section on its outer circumferential surface that is adapted to the internal threaded hole, thereby facilitating the threaded connection between the adjusting knob 62 and the adjusting rod 61.

[0034] The lengths of both the first puncture device 2 and the second puncture device 3 are greater than 25 cm. The outer diameter of the first puncture device 2 is no greater than 2 mm, and the outer diameter of the second puncture device 3 is no greater than 3 mm, to effectively ensure that the first puncture device 2 and the second puncture device 3 smoothly pass through the cervical opening of the uterus 8 and enter the uterine cavity 81. In addition, both the first puncture device 2 and the second puncture device 3 are cylindrical or flat. When the first puncture device 2 is flat, its width is no greater than 2 mm and its thickness is no greater than 1.5 mm. When the second puncture device 3 is flat, its width is no greater than 3 mm and its thickness is no greater than 1.5 mm. Furthermore, the inner diameter of the cavity 31 of the second puncture device 3 is no greater than 1 mm.

[0035] The puncture length of the puncture needle 4 is 15-20mm to effectively ensure that the puncture needle 4 is smoothly inserted into the scar diverticulum 82 from above.

[0036] The first puncture device 2 has a first scale 22 on its outer surface along its length, so that the medical operator can quickly know the insertion depth of the first puncture device 2. The second puncture device 3 has a second scale 34 on its outer surface along its length, so that the medical operator can quickly know the insertion depth of the second puncture device 3.

[0037] The above are merely some specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be considered as infringing upon the protection scope of the present invention.
