Description

A wireless illuminated vaginal speculum utilizing the principle of magnetic coupling resonance Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a wireless illuminated vaginal speculum utilizing the principle of magnetic coupling resonance. Background Technology

[0002] Speculae are widely used in obstetrics and gynecology. They are required for physical examinations and various gynecological surgical procedures.

[0003] For a long time, the issue of illumination inside the speculum during gynecological examinations or surgeries has plagued clinicians. The current common clinical solution is to place a light behind the surgeon or operator. There are also solutions that integrate the lighting device into the speculum itself, but these all require additional batteries or external power cords.

[0004] Most endoscopes used in clinical practice today lack built-in lighting. Endoscopes with lighting are typically battery-powered, requiring additional lighting equipment or batteries to address illumination issues during surgery and procedures. These endoscopes present several problems: 1. The lighting equipment is often heavy and difficult to move, making it unsuitable for special situations such as outpatient visits; 2. During operation, the lighting is often placed behind the surgeon, making it difficult for the light source to directly illuminate the surgical and operational areas. Furthermore, the surgeon's body inevitably blocks the light, resulting in less than ideal illumination; 3. It increases costs and occupies operating room space; 4. Endoscopes are mostly disposable, battery-powered operation is cumbersome, battery consumption is high, and subsequent recycling and disposal costs are significant; 5. Current endoscopes often rely on rotating screws and knobs to fix and control the angle between the upper and lower blades, which is time-consuming and labor-intensive.

[0005] Therefore, there is an urgent clinical need for a disposable endoscope that has its own light source, does not require battery power, and does not need to be connected to the outside world by wires.

[0006] In recent years, contactless power transfer technology has developed rapidly. Among them, magnetically coupled resonant wireless power transfer technology mainly utilizes the principle of magnetic coupling resonance. It employs two electromagnetic systems with the same resonant frequency and high quality factor. When the transmitting coil operates at a specific frequency, electromagnetic coupling resonance occurs in the receiving coil at a certain distance. High-frequency electromagnetic energy is exchanged between the two coils in a large proportion. When a load is connected to the receiving coil, the load absorbs a portion of the energy, thus achieving wireless power transmission. This wireless power transfer technology eliminates the dependence on wires and batteries, providing a completely new solution for power supply in specialized fields such as medicine. Its transmission distance can reach meters, while its transmission power and efficiency are high, and it is generally unaffected by spatial obstacles. It consumes only one millionth of the electrical energy of traditional electromagnetic induction power supply technology. When the transmitting end is energized, the transmitting coil does not emit electromagnetic waves but only forms a non-radiative magnetic field around it. This magnetic field couples with the receiving coil at the receiving end, exciting the receiving coil and providing power to the circuit, thus transmitting electrical energy at minimal cost. Its magnetic field strength is similar to that of the Earth's magnetic field, and it will not have adverse effects on the body or other equipment. Currently, pacemakers and cochlear implants powered by resonant magnetic coupling are already in use.

[0007] Therefore, applying wireless power transmission technology to vaginal speculum can greatly solve the clinical use problems faced by traditional speculum.

[0008] Utility Model Content

[0009] The technical problem to be solved by this utility model is to provide a wireless illuminated vaginal speculum that utilizes the principle of magnetic coupling resonance to address the shortcomings of the prior art. In this device, the speculum that comes into contact with the human body is disposable, while the power supply base can be used for a long time. The device is simple to operate, convenient to use, and has good lighting effect, which provides convenience for clinical operation and can be widely applied.

[0010] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a wireless illumination vaginal speculum using the principle of magnetic coupling resonance, characterized in that it includes an upper blade and a lower blade, the lower blade is provided with connecting holes on both sides, the upper blade is fixedly installed with connecting posts on both sides, the connecting posts are rotatably installed in the connecting holes, the upper blade can rotate relative to the lower blade, so that the front ends of the upper blade and the lower blade are close to or far away, and when they are far away, they have an expansion effect, which is convenient for use.

[0011] An observation window is provided in the middle of the lower blade near the corner. When the front ends of the upper and lower blades are far apart, observation or operation can be performed through the observation window.

[0012] A wireless receiver base is fixedly connected to the upper part of the upper blade near the corner. A small receiving coil is provided inside the wireless receiver base. A light is fixedly installed at the front end of the wireless receiver base. The receiving coil is electrically connected to the light.

[0013] It also includes a power supply base, which comprises a gel pad and a wireless transmitter, the wireless transmitter being embedded within the gel pad.

[0014] The wireless transmitter is equipped with a transmitting coil, which is used to convert electrical energy into electromagnetic energy, and the receiving coil is used to convert electromagnetic energy into electrical energy.

[0015] The transmitting and receiving resonant circuits corresponding to the transmitting and receiving coils have the same resonant frequency. Utilizing the principle of electromagnetic coupling, the alternating magnetic field generated by the transmitting coil of the power source is coupled to the non-contact receiving coil of the load, thereby achieving non-contact power transfer between the power source and the load. In other words, energy coupling and transfer are achieved through the resonance of the magnetic fields at the same frequency between the transmitting and receiving coils. This method features long transmission distance, high transmission power and efficiency, and is unaffected by spatial obstacles.

[0016] The power supply base converts electrical energy into electromagnetic energy through a transmitting coil, and the receiving coil generates an induced current through the principle of electromagnetic induction to provide power to the lighting lamp. The lighting lamp illuminates from the upper blade, which facilitates the operation and avoids the obstruction of light by external wires and other factors.

[0017] The lower blade has a mounting hole on its upper side and the upper blade has a horizontally oriented slot. An adjusting shaft is movably installed in the mounting hole and the slot. A clamping plate is fixedly installed on the adjusting shaft. The clamping plates are symmetrically arranged on the upper and lower sides of the adjusting shaft. The clamping plates are spaced at the same distance and the net distance between the clamping plates is equal to the wall thickness of the upper blade.

[0018] The height of the slotted hole is equal to the diameter of the adjusting shaft, and the width of the slotted hole is equal to the edge distance of the clamping plate. When the adjusting shaft is rotated, and the clamping plate is parallel to the slotted hole, it can pass through the slotted hole. At this time, the upper blade can rotate relative to the lower blade. As the upper blade rotates, its lower part is positioned on different clamping plate components. Rotating the adjusting shaft then makes the clamping plate perpendicular to the slotted hole, thus locking the upper blade and preventing it from rotating relative to the lower blade. The clamping plate thus limits and fixes the upper blade.

[0019] Preferably, a limiting block is fixedly installed at one end of the crossbar near the lower blade, and a torsion plate is fixedly installed at the other end of the crossbar. The crossbar can be rotated by the torsion plate so that the clamping plate is parallel or perpendicular to the strip hole, thereby facilitating the adjustment of the position and angle of the upper and lower blades and making operation easier.

[0020] Preferably, a pressure sensor is provided on the gel pad, and the pressure sensor is electrically connected to the power supply base through a control circuit. The gel pad is placed under the patient to position the power supply base, facilitating adjustments to the patient's position and ensuring stable power supply from the wireless transmitter to the wireless receiver base. When the pressure sensor detects pressure, the control circuit activates the power supply base, and the wireless transmitter within the power supply base begins operation.

[0021] Preferably, the upper and lower blades are made of transparent medical-grade plastic, which is inexpensive and easy to observe.

[0022] This utility model has the following advantages compared with the prior art:

[0023] 1. This utility model is equipped with a wireless transmitter and a wireless receiver base. Through the cooperation of the transmitting coil and the receiving coil, the power supply base supplies power to the lighting lamp, providing direct illumination on the upper blade. This avoids the problem of light obstruction, resulting in good lighting effect. The power supply base can be used for a long time and is inexpensive, solving the problems of high resource consumption and cost associated with disposable batteries. The gel pad can be directly laid on the hospital bed, making it convenient to use, space-saving, and compact, easy to carry for use, and suitable for large-scale promotion.

[0024] 2. This utility model has a pressure sensor installed on the gel pad. When a gynecological examination or surgery is performed, the gel pad bears the patient's weight, the pressure sensor is pressed and connects the circuit, the wireless transmitter works, and the transmitting coil generates electrical energy in the receiving coil through the electromagnetic coupling principle, so that the light is turned on. After the operation is completed, the patient leaves the gel pad, the pressure sensor no longer bears pressure, the wireless transmitter is powered off, the light is turned off, and the automatic start and stop of the light saves energy.

[0025] 3. This utility model has an adjustment shaft on the lower blade, and a clamping plate is set at equal intervals on the adjustment shaft. The upper blade can be clamped by the clamping plate, so that the upper blade cannot rotate, thus achieving a positioning effect. A strip hole is set on the upper blade so that the adjustment shaft will not affect the rotation of the upper blade. It saves time and effort when fixing the distance between the upper and lower blades, and is simple to operate and convenient to use.

[0038] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0040] As shown in Figures 1-3, this utility model provides a wireless illuminated vaginal speculum utilizing the principle of magnetic coupling resonance, including an upper blade 1 and a lower blade 2. The lower blade 2 has connecting holes 4 on both sides, and connecting posts 3 are fixedly installed on both sides of the upper blade 1. The connecting posts 3 are rotatably installed in the connecting holes 4. The upper blade 1 can rotate relative to the lower blade 2, so that the front ends of the upper blade 1 and the lower blade 2 are close to or far away. When they are far away, they have an expansion effect, which is convenient for use.

[0041] An observation window 14 is provided in the middle of the lower blade 2 near the corner. When the front ends of the upper blade 1 and the lower blade 2 are far apart, observation or operation can be performed through the observation window 14.

[0042] A wireless receiver base 5 is fixedly connected to the upper part of the upper blade 1 near the corner. A small receiving coil 6 is provided inside the wireless receiver base 5. A lighting lamp 7 is fixedly installed at the front end of the wireless receiver base 5. The receiving coil 6 is electrically connected to the lighting lamp 7.

[0043] It also includes a power supply base, which includes a gel pad 13 and a wireless transmitter 8, the wireless transmitter 8 being embedded in the gel pad 13.

[0044] The wireless transmitter 8 is equipped with a transmitting coil, which is used to convert electrical energy into electromagnetic energy, and the receiving coil 6 is used to convert electromagnetic energy into electrical energy.

[0045] The transmitting and receiving resonant circuits corresponding to the transmitting coil and receiving coil 6 have the same resonant frequency to obtain unified inductance parameters and improve energy transmission efficiency. Utilizing the principle of electromagnetic coupling, the alternating magnetic field generated by the power supply transmitting coil is coupled to the non-contact load receiving coil, thereby achieving non-contact energy transmission between the power supply and load ends. That is, energy coupling and transfer are achieved through the resonance of the same-frequency magnetic fields between the transmitting coil and receiving coil 6. This method features long transmission distance, high transmission power and efficiency, and is generally unaffected by spatial obstacles.

[0046] The power supply base converts electrical energy into electromagnetic energy through the transmitting coil. The receiving coil 6 generates an induced current through the principle of electromagnetic induction, which provides power to the lighting lamp 7. The lighting lamp 7 provides illumination from the upper blade 1, which facilitates the operation and avoids the obstruction of light by external wires and other factors.

[0047] The lower blade 2 has a mounting hole on its upper side at the bottom, and the upper blade 1 has a horizontally arranged strip hole 9 at the bottom. An adjusting shaft 10 is movably installed in the mounting hole and the strip hole 9. A clamping plate 11 is fixedly installed on the adjusting shaft 10. The clamping plates 11 are symmetrically arranged on the upper and lower sides of the adjusting shaft 10. The clamping plates 11 are spaced at the same distance, and the net distance between the clamping plates 11 is equal to the wall thickness of the upper blade 1.

[0048] The height of the strip hole 9 is equal to the diameter of the adjusting shaft 10, and the width of the strip hole 9 is equal to the edge distance of the clamping plate 11. When the adjusting shaft 10 is rotated, and the clamping plate 11 is parallel to the strip hole 9, the clamping plate 11 can just pass through the strip hole 9. At this time, the upper blade 1 can rotate relative to the lower blade 2. As the upper blade 1 rotates, the lower part of the upper blade 1 is located on different clamping plates 11. At this time, when the adjusting shaft 10 is rotated, so that the clamping plate 11 is perpendicular to the strip hole 9, the clamping plate 11 clamps the upper blade 1, so that the upper blade 1 cannot rotate relative to the lower blade 2. The clamping plate 11 plays a limiting and fixing role for the upper blade 1.

[0049] In this embodiment, a limiting block is fixedly installed at one end of the crossbar 10 near the lower blade 2, and a torsion piece 12 is fixedly installed at the other end of the crossbar 10. The crossbar 10 can be rotated by the torsion piece 12 so that the clamping plate 11 is parallel or perpendicular to the strip hole 9, thereby facilitating the adjustment of the position and angle of the upper blade 1 and the lower blade 2, and making operation convenient.

[0050] In this embodiment, a pressure sensor is installed on the gel pad 13. The pressure sensor is electrically connected to the power supply base through a control circuit. The gel pad 13 is placed under the patient to position the power supply base, facilitating adjustments to the patient's position and ensuring stable power supply from the wireless transmitter 8 to the wireless receiver base 5. When the pressure sensor detects pressure, the control circuit activates the power supply base, and the wireless transmitter 8 within the power supply base begins operation.

[0051] In this embodiment, the upper blade 1 and the lower blade 2 are made of transparent medical-grade plastic, which is inexpensive and easy to observe.

[0052] When using, place the gel pad 13 under the patient and determine the position of the power supply base.

[0053] When the patient lies on the gel pad 13, the pressure sensor detects the pressure and activates the power supply base through the control circuit. The wireless transmitter 8 inside the power supply base starts working, and the transmitting coil inside the wireless transmitter 8 converts electrical energy into electromagnetic energy.

[0054] First, place the front ends of the upper leaf 1 and the lower leaf 2 together tightly, and then insert the front ends of the upper leaf 1 and the lower leaf 2 into the patient's vagina.

[0055] Rotate the adjusting shaft 10. When the clamping plate 11 is parallel to the strip hole 9, the clamping plate 11 can just pass through the strip hole 9. At this time, the upper blade 1 can rotate relative to the lower blade 2.

[0056] When the patient's vagina is dilated to the appropriate degree, rotate the adjusting shaft 10 so that the clamping plate 11 is perpendicular to the strip hole 9. At this time, the upper blade 1 cannot rotate relative to the lower blade 2, and the clamping plate 11 plays a limiting and fixing role on the upper blade 1.

[0057] At this time, the wireless receiver base 5 is located above the power supply base. The receiving coil 6 inside the wireless receiver base 5 generates an induced current through the principle of electromagnetic induction, which provides power to the lighting lamp 7. The lighting lamp 7 provides illumination from the upper blade 1, which facilitates the operation and avoids the obstruction of light by external wires and other factors.

[0058] At this time, the front ends of the upper blade 1 and the lower blade 2 are far apart, and observation or operation can be performed through the observation window 14.

[0059] After the surgery, the patient left the gel pad 13, the pressure sensor could not detect any pressure, and the power supply base stopped working.

[0060] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any simple modifications, alterations, and equivalent changes made to the above embodiments based on the technical essence of this utility model shall still fall within the protection scope of this utility model.
