Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a myoma enucleation device for gynecology. Background Art

[0002] Uterine myoma is a benign tumor originating from the hyperplasia of uterine smooth muscle cells, which may cause symptoms such as irregular menstruation, abdominal pain and a sense of compression. In severe cases, it will affect the quality of life of patients. Myoma enucleation is a commonly used surgical treatment method aimed at removing the myoma on the uterus. Although most myomas are benign, timely treatment is still very important.

[0003] Traditional uterine myoma enucleation surgery usually adopts the method of making an abdominal incision. By inserting various enucleation instruments into the uterus and using an enucleation knife to separate and remove the myoma. For smaller myomas, they can be directly taken out from the incision. However, for larger myomas, due to their large volume and the relatively small abdominal opening, medical staff need to place the myoma under the incision, gradually cut and separate it before taking it out. This direct cutting method has certain risks, which may cause myoma fragments to remain in the body, increasing the possibility of postoperative complications. In addition, the surface of the myoma is smooth and its texture is relatively hard, and the existing surgical clips are prone to loosen and slip during the operation, further increasing the difficulty and risk of the operation.

[0004] In the prior art, some improved uterine myoma enucleation devices have been proposed. For example, the uterine myoma enucleation device with the authorization announcement number CN219000473U designs an umbrella-shaped head structure for covering the surface of the myoma, and uses a cutting knife to cut along the edge of the umbrella-shaped head to achieve a safer and more convenient resection and separation effect. This device improves the surgical safety to a certain extent, but there are still deficiencies: for larger myomas, although they can be protected by the umbrella-shaped structure, due to the size limitation of the myoma, the subsequent problem of taking out the myoma is still difficult to solve. At the same time, this method of cutting at the uterine orifice also has risks, making the overall treatment effect have potential hazards and increasing the uncertainty and complexity of the operation.

[0005] Therefore, it is necessary to propose a myoma enucleation device for gynecology that can address the difficulties in removing larger myomas, the slipping of surgical clips and the retention of fragments, so as to improve the surgical safety and reduce the risk of postoperative complications. Summary of the Invention

A second right-angle plate is hinged to the hinge seat at the rearmost end through a hinge piece. A connecting piece is arranged on the second right-angle plate, and an insertion ring adapted to the connection of the connecting piece is arranged on the installation cylinder.

[0011] As an improvement of the above solution, the hinge piece includes a fitting pad, a rotating rod and a screw. Rotating rods are rotatably arranged on the hinge seats.

[0032] In addition, the terms "first", "second", and "third" are for descriptive purposes only and should not be construed as indicating or implying relative importance. The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. It should be noted that the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] Embodiment 1: A myoma dissection device for gynecology, as Figures 1-6 shown, includes: An installation cylinder 1, which is a hollow installation carrier. An extension frame 11 is fixedly arranged at the bottom end of the installation cylinder 1, and the end of the extension frame 11 is in a closed ring structure; An electric lead screw 2 is installed inside the top end of the installation cylinder 1, and the lead screw body of the electric lead screw 2 extends upward. A sliding frame 21 is threadedly arranged on the lead screw body of the electric lead screw 2. The lower end of the sliding frame 21 is slidably passed through the installation cylinder 1 and is allowed to be driven by the electric lead screw 2 to drive the sliding frame 21 to move up and down. The lower half of the sliding frame 21 is placed in the peripheral area of the extension frame 11. When the sliding frame 21 is placed at the top end of the electric lead screw 2, the sliding frame 21 and the bottom end of the extension frame 11 are flush. Four clamping plates 22 are circumferentially and spacedly hinged on the ring structure at the bottom end of the extension frame 11. The clamping plates 22 are arc-shaped plates, and serrated structures are arranged at intervals on their inner walls to enhance the grasping ability of the myoma tissue, prevent slippage during the dissection process, improve the safety and efficiency of the operation. Longitudinal chutes 221 are opened on the clamping plates 22. Grooves adapted to the number and layout of the clamping plates 22 are opened at the bottom end of the sliding frame 21. Push rods 222 slidably embedded in adjacent chutes 221 are arranged in the grooves to achieve precise control of the opening and closing actions of the clamping plates 22. The electric lead screw 2 drives the sliding frame 21 to move up and down, and the push rods 222 move synchronously with the sliding frame 21 and slide along the chutes 221 on the clamping plates 22, thereby driving the clamping plates 22 to rotate on the extension frame 11. When the sliding frame 21 moves up, the clamping plates 22 expand accordingly; when the sliding frame 21 moves down, the clamping plates 22 close accordingly, realizing the opening and closing actions of the clamping plates 22, ensuring that the actions of the clamping plates 22 are stable and controllable, and can flexibly adjust the opening and closing degree according to the size and shape of the myoma, meeting the precise grasping requirements for different types of myomas during the treatment process; The extraction tube 3 is slidably disposed inside the installation cylinder 1 and the extension frame 11. The extraction tube 3 can be externally connected to an extraction device for processing the excised myoma tissue. A slicing tube 31 is provided at the end of the extraction tube 3. The connection end of the extraction tube 3 and the slicing tube 31 is made of a flexible tube material. An electric cutting ring for slicing the myoma is provided at the end of the slicing tube 31. The electric cutting ring can accurately slice the myoma tissue, especially suitable for the treatment of larger myomas. Through the fine cutting of the electric cutting ring, it can ensure that the myoma is completely and smoothly removed from the incision, effectively solve the problem of difficult removal of large myomas, avoid myoma residue at the same time, and reduce the risk of postoperative complications. A limiting ring 32 is provided on the inner wall at the end of the extension frame 11. A guiding groove is circumferentially formed on the inner wall of the limiting ring 32. Two clamping balls 331 are rotatably and slidably disposed in the guiding groove. A moving ring 33 is disposed between the two clamping balls 331. Symmetrically arranged sliding blocks 332 are disposed inside the moving ring 33. The sliding blocks 332 are respectively embedded on one side of the slicing tube 31 and are slidably engaged with each other.

[0034] During use, first, limit and expand the abdominal incision to ensure that the device can smoothly extend into the abdomen and reach the inside of the uterus. Then, determine the specific position of the myoma. Next, start the electric lead screw 2 to drive the sliding frame 21 to move up and down, and drive the clamping plate 22 to open and close by means of the push rod 222. Since the clamping plate 22 has an arc-shaped structure and a serrated design, it can closely fit the surface of the myoma to achieve stable grasping and prevent falling off during subsequent peeling and taking processes. Subsequently, peel the grasped myoma and move it below the incision, and then confirm that the extraction tube 3 is externally connected to the extraction device. Push the extraction tube 3 to drive the slicing tube 31 to extend downward. The slicing tube 31 slides along the sliding block 332 until the electric cutting ring contacts the myoma and accurately slices the myoma. During this process, the clamping balls 331 adapt to the movement of the slicing tube 31 under the guidance of the guiding groove. At the same time, the moving ring 33 rotates or slides on the limiting ring 32 to ensure that the slicing action is stable and efficient. Finally, the sliced myoma is smoothly extracted through the extraction tube 3 to complete the entire myoma peeling process.

[0035] It can be seen that the operation process is reasonably designed, ensuring the coherence of myoma grasping, slicing, and extraction, thus effectively dealing with the problems of difficult removal of large myomas, slipping of surgical clips, and retention of fragments, significantly improving the surgical efficiency and safety, and reducing the risk of postoperative complications.

[0036] Embodiment 2: On the basis of Embodiment 1, as Figure 1 、 Figure 5 and Figure 7As shown in the figure, it further includes a guide frame 4 and a clamping frame 41. Guide frames 4 are provided on both the left and right sides of the installation cylinder 1. A clamping frame 41 for fitting and restricting the position of the extraction tube 3 is slidably penetrated on each guide frame 4. The two clamping frames 41 have roller structures at their ends close to each other. By pushing the clamping frame 41 to move, the position of the extraction tube 3 can be effectively restricted, ensuring its stability when not in use. At the same time, with the flexible adjustment of the clamping frame 41, precise control of the extraction tube 3 can also be achieved, thereby improving the operation accuracy during its use.

[0037] As Figure 7 shown in the figure, it further includes a support plate 42, a rotating frame 43 and a torsion spring 44. Support plates 42 are provided on both the front and rear sides of the clamping frame 41. A rotating frame 43 is rotatably arranged between the two support plates 42 on the same side. The rotating frame 43 is inserted and matched with the guide frame 4 on the same side, and a torsion spring 44 is arranged between the rotating frame 43 and the corresponding support plate 42. By pushing the rotating frame 43 to rotate, the restriction on the clamping frame 41 is released. At this time, the torsion spring 44 deforms accordingly. When the clamping frame 41 is adjusted to fit the extraction tube 3, the rotating frame 43 is released, and the torsion spring 44 returns to its original state and drives the rotating frame 43 to reset, so that the rotating frame 43 is inserted into the guide frame 4, thereby fixing the position of the clamping frame 41 to ensure its stability and reliability.

[0038] As Figure 1 、 Figure 8 and Figure 9 shown in the figure, it further includes a support rod 5, an adjusting rod 51, a first right-angle plate 52, a hinge seat 53, a hinge member, a second right-angle plate 57, a connecting member and an insertion ring 59. There is one support rod 5 and two adjusting rods 51. Hinge seats 53 are provided at the ends of the support rod 5 and the adjusting rods 51. A first right-angle plate 52 is also provided at the end of the adjusting rod 51. The adjacent first right-angle plates 52 and the hinge seats 53 are hinged together through hinge members. A second right-angle plate 57 is hinged to the hinge seat 53 at the rearmost end through a hinge member. A connecting member is provided on the second right-angle plate 57, and an insertion ring 59 adapted to be inserted and matched with the connecting member is provided on the installation cylinder 1. Through the coordinated cooperation of the above-mentioned components, a multi-joint support and adjustment assembly is formed, which can adjust the overall posture and angle of the device according to the actual needs during the operation, and is suitable for the requirements of patients with different body types and surgical sites.

[0039] As Figure 8 and Figure 9As shown, the hinge includes a fitting pad 54, a rotating rod 55, and a screw 56. Rotating rods 55 are rotatably arranged on the hinge seats 53. At the end of each rotating rod 55, there is a screw 56 that is threadedly connected to the adjacent right-angle plate 1 52 or right-angle plate 2 57. On one side of the hinge seat 53, there is also a fitting pad 54. The fitting pad 54 is in close contact with the right-angle plate 1 52 or right-angle plate 2 57 and forms a frictional fit. When it is necessary to firmly fix the positions of each joint, first hold the corresponding right-angle plate 1 52 or right-angle plate 2 57 by hand, and then rotate the screw 56. Driven by the thread, the screw 56 drives the corresponding right-angle plate 1 52 or right-angle plate 2 57 to move towards the fitting pad 54 until it is in close fit with the fitting pad 54. With the friction of the fitting pad 54, the effective restriction and fixation of the joint position are achieved.

[0040] As Figure 8 and Figure 9 shown, the connecting piece includes a plug rod 58 and an elastic card 581. On both sides of the right-angle plate 2 57, there are plug rods 58 that are inserted and matched with the insertion ring 59. On each plug rod 58, there is an elastic card 581 that is clamped and matched with the insertion ring 59. The insertion design of the plug rod 58 and the insertion ring 59 enables the right-angle plate 2 57 to be quickly assembled or separated from the installation cylinder 1, simplifying the preparation process and assembly work before the operation. At the same time, the clamping connection method of the elastic card 581 and the insertion ring 59 enhances the stability of the connection, achieving a fast, firm, and reliable connection effect, providing an important guarantee for the operation convenience and surgical safety of the entire device.

[0041] As Figure 1 , Figure 10 and Figure 11 shown, it also includes a fitting set 6, a syringe 61, a delivery tube 62, and an injection head 621. On both sides of the installation cylinder 1, there are also fitting sets 6. Inside each fitting set 6, there is a syringe 61 for loading injection liquid. On both sides of the installation cylinder 1, there is also an embedded delivery tube 62 that extends into the adjacent splint 22. The head end of the delivery tube 62 is connected to the syringe barrel of the syringe 61 on the same side, and the tail end of the delivery tube 62 is provided with an injection head 621 for spraying drugs. Combining the above components, the delivery tube 62 directly delivers the liquid medicine in the syringe 61 to the surface or surrounding tissues of the myoma near the splint 22, and accurately penetrates and injects it into the target area through the injection head 621, ensuring that the drug can accurately act on the myoma or surrounding tissues, thereby simplifying the drug delivery process. Just push the syringe 61 to complete the drug delivery without additional operations, saving the operation time.

[0042] The above has introduced the present application in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope.
