Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a vaginal dilator. Background Art

[0002] A vaginal dilator is a conventional instrument for vaginal examination and surgical operations. Its principle is to insert the sliding pin on the lower leaf of the dilator into the sliding hole of the upper leaf, move the upper leaf up and down to dilate the vagina, and lock the expansion range with the teeth on the handle; or use a rotating shaft to dilate, and use the teeth to lock the expansion size to achieve the purpose of expanding the size of the vagina.

[0003] Transvaginal operation and surgery is one of the common approaches in obstetrics and gynecology. Drainage of bleeding during surgery is a common problem. The current solution is to use an aspirator connected to a suction tube to suction the surgical site. However, due to the small operating space at this site, the suction tube partially blocks the surgical field, resulting in the inability to promptly detect the patient's bleeding point during the operation, making the suction operation inconvenient. Due to the small operating space, the suction tube needs to be removed after the observation is completed. When the suction tube is removed, the bleeding point may still continue. When the bleeding is turbulent, it is more difficult for the operator to determine the bleeding location, resulting in increased difficulty and risk of the operation. Summary of the invention

[0004] Therefore, the present invention aims to solve the problems in the prior art that it is difficult to determine the bleeding location, the suction operation is inconvenient, and the observation of the surgical field is affected when performing suction operation during surgery, thereby providing a vaginal dilator.

[0005] In order to solve the above technical problems, the technical solution of the present invention is as follows:

[0007] Furthermore, both ends of the drainage tube away from the handle are through-type, and the other end of the drainage tube is suitable for introducing an aspirator.

[0008] Furthermore, a groove is provided on the handle, a partition is provided in the groove, a drainage channel is formed between the handle and the partition, the other end of the drainage tube is connected to the drainage channel, the drainage channel is through-set at one end away from the drainage tube, and the suction device is suitable for being introduced from the drainage channel.

[0009] Furthermore, the top of one end of the upper leaf connected to the handle is open, and one end of the tube body is suitable for passing through the opening of the upper leaf.

[0010] Furthermore, mounting plates are provided on opposite sides of the upper leaf near one end of the handle, mounting posts are provided at the bottom of the inner side of the mounting plates, and mounting holes matching the mounting posts are provided at the bottom of the side walls of the handle.

[0011] Furthermore, the mounting hole is L-shaped, the aperture of the L-shaped mounting hole at a turning point is matched with the outer diameter of the mounting column, and the aperture of one end of the L-shaped mounting hole close to the upper lobe is larger than the aperture of the L-shaped mounting hole at a turning point; when the expander is in an expanded state, the mounting column is located on one end of the L-shaped mounting hole close to the upper lobe, and when the expander is in a merged state, the mounting column is located on the other end of the L-shaped mounting hole.

[0012] Furthermore, a strip-shaped limiting groove is provided on one end of the mounting plate close to the upper leaf, and a limiting column located in the limiting groove is provided on the outer side wall of the handle.

[0013] Furthermore, a fixing strip is provided at the top of one end of the two mounting plates away from the upper leaf.

[0014] Furthermore, flexible material is provided at one end of the upper leaf and the lower leaf away from the handle.

[0015] Furthermore, a plurality of drainage holes are provided on the side wall of the drainage tube, and the aspirator is suitable for extending out from the drainage holes; and two tube bodies are provided, including a first tube body suitable for accommodating a lens and a second tube body suitable for accommodating a lighting component.

[0016] The technical solution of the present invention has the following advantages:

[0017] 1. The vaginal dilator provided by the present invention, by placing the drainage tube inside, does not occupy additional operating space, and also avoids affecting the surgical field, so that surgery can be performed without removing the drainage tube during the operation. In this way, if a large amount of bleeding or continuous bleeding occurs during the operation, the overflowing blood can still be sucked out and discharged to the patient's body, avoiding the presence of blood in the dilator and affecting the observation of the surgical field; by placing the tube body accommodating the lens and the lighting component inside, it is convenient for the operator to illuminate the surgical field when performing the operation, and at the same time, it can avoid the linear body of the lens and the lighting component affecting the surgical field, and avoid the overlap of surgical instruments to limit the operation field.

[0018] 2. The vaginal dilator provided by the present invention has two ends of the drainage tube away from the handle that are through-set, and the other end of the drainage tube is suitable for introducing an aspirator. In this way, the aspirator is located in the drainage tube during surgery, which can prevent the aspirator's line from affecting the surgical field and prevent the aspirator from overlapping with other surgical instruments and limiting the surgical field.

[0019] 3. The vaginal dilator provided by the present invention has a groove on the handle, a partition is arranged in the groove, a drainage channel is formed between the handle and the partition, the other end of the drainage tube is connected to the drainage channel, the end of the drainage channel away from the drainage tube is through-set, and the suction device is suitable for being introduced from the drainage channel. In this way, by using a partition on the handle to separate the drainage channel, the suction device enters from the drainage channel, which can prevent the suction device on the handle from affecting the operator's holding of the dilator, and prevent the suction device from restricting the operator's operation of the dilator, and at the same time prevent the suction device from affecting the operation of the dilator when using the dilator.

[0020] 4. The vaginal dilator provided by the present invention has an L-shaped mounting hole, the diameter of the hole at the turning point of the L-shaped mounting hole is matched with the outer diameter of the mounting post, and the diameter of the end of the L-shaped mounting hole close to the upper leaf is larger than the diameter of the hole at the turning point of the L-shaped mounting hole; when the dilator is in the expanded state, the mounting post is located at the end of the L-shaped mounting hole close to the upper leaf, and when the dilator is in the merged state, the mounting post is located at the other end of the L-shaped mounting hole. With such an arrangement, when the dilator is expanded, the mounting post can be pushed from the turning point of the mounting hole to the end of the mounting hole close to the upper leaf. Since the diameter of the hole at the turning point of the L-shaped mounting hole is matched with the outer diameter of the mounting post, and the diameter of the end of the L-shaped mounting hole close to the upper leaf is larger than the diameter of the turning point of the L-shaped mounting hole, the dilator can be kept in the expanded state continuously.

[0021] 5. The vaginal dilator provided by the present invention has a strip-shaped limit groove on one end of the mounting plate close to the upper leaf, and a limit column located in the limit groove is provided on the outer wall of the handle. In this way, by providing the limit column and the strip-shaped limit groove, the limit column can always move only in the strip-shaped limit groove, thereby limiting the rotation range of the upper leaf when rotating.

[0022] 6. In the vaginal dilator provided by the present invention, a fixing strip is arranged at the top of one end of the two mounting plates away from the upper leaf. With such arrangement, since the top of the end of the upper leaf connected to the handle is open, the dilator can be opened by pressing the fixing strip; at the same time, the fixing strip is arranged at the end of the upper leaf, and the lever principle can make it easier and more labor-saving to press the fixing strip.

[0023] 7. In the vaginal dilator provided by the present invention, the ends of the upper leaf and the lower leaf away from the handle are both provided with flexible materials, so that when the dilator enters the human body, it is in flexible contact with the human body, which can reduce the pain of the patient.

[0024] 8. The vaginal dilator provided by the present invention has a plurality of drainage holes on the side wall of the drainage tube, and the aspirator is suitable for extending from the drainage holes; the tube body is provided with two, including a first tube body suitable for accommodating a lens and a second tube body suitable for accommodating an illuminating element. With such a configuration, the aspirator can be conveniently extended from any drainage hole to aspirate the spilled blood. By providing two tube bodies to accommodate the lens and the illuminating element respectively, the wires of the lens and the illuminating element can be prevented from being entangled.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0034] like Figure 1-Figure 3 A vaginal dilator shown in the figure comprises a handle 7, a lower leaf 2 bent and connected to the handle 7, and an upper leaf 1 rotatably connected to one end of the handle 7; a drainage groove 3 is provided at the bottom of the lower leaf 2, a drainage tube 4 suitable for being connected to an aspirator is provided in the drainage groove 3, a tube body suitable for accommodating a lens and a lighting component is provided on the inner side of the upper leaf 1 close to the lower leaf 2, the drainage tube 4 is provided closely to the bottom wall of the drainage groove 3, and the tube body is provided closely to the inner top wall of the upper leaf 1.

[0035] This vaginal dilator, by having the drainage tube 4 built in, does not occupy additional operating space and avoids affecting the surgical field, so that surgery can be performed without removing the drainage tube 4. In this way, even if there is a lot of bleeding or continuous bleeding during the operation, the overflowing blood can still be sucked out of the patient's body, avoiding the presence of blood in the dilator and affecting the observation of the surgical field; by having the tube body accommodating the lens and the lighting component built in, it is convenient for the operator to illuminate the surgical field when performing the operation, and at the same time, it can avoid the linear body of the lens and the lighting component affecting the surgical field, and avoid the overlapping of surgical instruments to limit the operating field.

[0036] In this embodiment, both ends of the drainage tube 4 away from the handle 7 are through-set, and the other end of the drainage tube 4 is suitable for introducing the suction device. In this way, the suction device is located in the drainage tube 4 during the operation, which can prevent the suction device's line from affecting the surgical field and avoid the suction device overlapping with other surgical instruments to limit the operation field.

[0037] In this embodiment, a groove is provided on the handle 7, and a partition 8 is provided in the groove at intervals. A drainage channel 9 is formed between the handle 7 and the partition 8. The other end of the drainage tube 4 is connected to the drainage channel 9, and the end of the drainage channel 9 away from the drainage tube 4 is through-set, and the aspirator is suitable for being introduced from the drainage channel 9. In this arrangement, by using the partition 8 on the handle 7 to separate the drainage channel 9, the aspirator is allowed to enter from the drainage channel 9, which can prevent the wire body of the aspirator on the handle 7 from affecting the operator's holding of the dilator, and prevent the wire body of the aspirator from restricting the operator's operation of the dilator, and at the same time prevent the aspirator from affecting the operation and use of the dilator when using the dilator.

[0038] In this embodiment, the top of one end of the upper leaf 1 connected to the handle 7 is open, and one end of the tube body is suitable for passing through the opening of the upper leaf 1.

[0039] In this embodiment, mounting plates 10 are provided on opposite sides of the upper leaf 1 near one end of the handle 7, mounting posts 11 are provided at the bottom inner side of the mounting plates 10, and mounting holes 12 matching the mounting posts 11 are provided at the bottom of the side wall of the handle 7.

[0040] In this embodiment, the mounting hole 12 is L-shaped, the aperture of the L-shaped mounting hole 12 at the bend is matched with the outer diameter of the mounting column 11, and the aperture of the end of the L-shaped mounting hole 12 close to the upper lobe 1 is larger than the aperture of the L-shaped mounting hole 12 at the bend; when the expander is in the expanded state, the mounting column 11 is located at the end of the L-shaped mounting hole 12 close to the upper lobe 1, and when the expander is in the merged state, the mounting column 11 is located at the other end of the L-shaped mounting hole 12. With such a configuration, when the expander is expanded, the mounting column 11 can be pushed from the bend of the mounting hole 12 to the end of the mounting hole 12 close to the upper lobe 1. Since the aperture of the L-shaped mounting hole 12 at the bend is matched with the outer diameter of the mounting column 11, and the aperture of the end of the L-shaped mounting hole 12 close to the upper lobe 1 is larger than the aperture of the L-shaped mounting hole 12 at the bend, the mounting part can be stuck in the L-shaped mounting hole 12 after the expander is expanded, thereby allowing the expander to continue to maintain the expanded state. Specifically, one end of the L-shaped mounting hole 12 close to the upper leaf 1 is tilted upward. This arrangement can prevent the mounting column 11 from sliding to the other end of the L-shaped mounting hole 12 after the expander is expanded, and can keep the expander in an open state at all times when no external force is applied.

[0041] In this embodiment, a strip-shaped limiting groove 13 is provided on one end of the mounting plate 10 close to the upper blade 1, and a limiting column 14 located in the limiting groove is provided on the outer wall of the handle 7. In this arrangement, by providing the limiting column 14 and the strip-shaped limiting groove 13, the limiting column 14 can always move only in the strip-shaped limiting groove 13, thereby limiting the rotation range of the upper blade 1 when rotating.

[0042] In this embodiment, a fixing strip 15 is provided at the top of one end of the two mounting plates 10 away from the upper leaf 1. In this way, since the top of the end of the upper leaf 1 connected to the handle 7 is open, the dilator can be opened by pressing the fixing strip 15; at the same time, the fixing strip 15 is located at the end of the upper leaf 1, and the lever principle can make it easier to press the fixing strip 15.

[0043] In this embodiment, the ends of the upper leaf 1 and the lower leaf 2 away from the handle 7 are both provided with flexible materials. Such a configuration enables the expander to be in flexible contact with the human body when entering the human body, which can reduce the pain of the patient.

[0044] In this embodiment, a plurality of drainage holes are provided on the side wall of the drainage tube 4, and the aspirator is suitable for extending from the drainage holes; two tube bodies are provided, including a first tube body 5 suitable for accommodating a lens and a second tube body 6 suitable for accommodating an illuminator. In this way, the aspirator can be conveniently extended from any drainage hole to aspirate the overflowed blood. By providing two tube bodies to accommodate the lens and the illuminator respectively, the wires of the lens and the illuminator can be prevented from being entangled.

[0045] In summary, this vaginal dilator, by placing the drainage tube 4 inside, does not occupy additional operating space and avoids affecting the surgical field, so that surgery can be performed without removing the drainage tube 4. In this way, even if heavy bleeding or continuous bleeding occurs during the operation, the overflowing blood can still be sucked out of the patient's body, avoiding the presence of blood in the dilator and affecting the observation of the surgical field; by placing the tube body accommodating the lens and the lighting component inside, it is convenient for the operator to illuminate the surgical field when performing the operation, and at the same time, it can avoid the linear body of the lens and the lighting component affecting the surgical field, and avoid the overlapping of surgical instruments to limit the operating field.

[0046] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
