Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, the present invention relates to a fire needle device with intelligent temperature control and rapid needle insertion. Background Art

[0002] Fire needle is a method of treating diseases by quickly inserting the tip of a needle that has been heated red into acupoints. As early as in "The Spiritual Pivot - Official Acupuncture", it was recorded that "For quenching acupuncture, when using a burning needle, it is used to treat arthralgia." "Treatise on Febrile Diseases" also discussed the indications of fire needle and the syndromes that are not suitable for treatment with fire needle. "Supplement to the Thousand Ducat Formulas" has the statement "For treating boils, carbuncles and sores, the needle should only be made extremely hot." "Compendium of Acupuncture and Moxibustion" summarized the experience of treating diseases with fire needles before the Ming Dynasty and can be referred to.

[0003] After retrieval, a fire needle device is disclosed in Chinese Patent No. CN113397968A, which includes a housing and a needle sleeve, a needle tool, a heating component, a transmission component and a control component provided on the housing. The control component receives an external force and transmits it to the needle tool through the transmission component, and the needle tool can be controlled through the control component. The fire needle is hidden by the needle sleeve to reduce the patient's fear. After positioning the puncture point, then operate the control component. The control component receives the operating force and transmits the force to the needle tool through the transmission component, so that the needle tool pops out in the needle sleeve, which is convenient to operate; before the needle tool pops out, the heating component can heat the tip of the needle tool. The fire needle pops out quickly. The acupoint can be positioned through the needle sleeve, and the preset insertion depth can be set by adjusting the position of the needle sleeve. Through the rotation of the transmission component, the popped fire needle can be quickly retracted into the needle sleeve, avoiding the fire needle staying in the body for too long due to the uneven operation skills of the operator. It improves the quality of fire needle puncture and drainage and enhances safety and operability.

[0004] When the needle tool of the above-mentioned existing fire needle device pops out, it needs to be manually operated and controlled. That is, when the tip of the needle is heated, the staff operates to pop out the tip of the needle. This method makes it impossible to accurately control the heating temperature of the tip of the needle. Or when the heating temperature of the tip of the needle reaches the preset range, the tip of the needle cannot be popped out in time, which may cause the tip of the needle to overheat or the tip of the needle to be popped out before reaching the preset temperature range, thereby affecting the treatment effect of the fire needle. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a fire needle device with intelligent temperature control and rapid needle insertion. The technical problem to be solved by the present invention is that in the existing fire needle device, the heating temperature cannot be accurately controlled, or when the heating temperature of the tip of the needle reaches the preset range, the tip of the needle cannot be popped out in time, which may cause the tip of the needle to overheat or the tip of the needle to be popped out before reaching the preset temperature range, thereby affecting the treatment effect of the fire needle.

[0006] To achieve the above object, the present invention provides the following technical solution: A fire needle device with intelligent temperature control and rapid needle insertion, comprising:

[0007] A handle, one axial end of the handle is provided with a sheath;

[0008] A connecting rod coaxially penetrates through the handle. One end of the connecting rod penetrating into the handle is coaxially fixed with a heat conduction rod. One end of the heat conduction rod away from the connecting rod is coaxially fixed with a needle tip. A perforation for the free passage of the heat conduction rod is provided on the sheath;

[0009] A heating component for heating the heat conduction rod;

[0010] A floating ring is arranged in the handle. A sliding cavity for engaging the floating ring is coaxially opened in the handle. The floating ring and the sliding cavity form a sliding fit. A heat conduction oil storage cavity is formed between the floating ring and the inner wall of the sliding cavity adjacent to the sheath. Heat conduction oil is stored in the heat conduction oil storage cavity. The connecting rod slidably penetrates through the floating ring;

[0011] A driving component for driving the connecting rod to move downward, so that the needle tip penetrates out of the perforation;

[0012] A release component for limiting the movement of the connecting rod, and when the floating ring moves upward, the limitation on the movement of the connecting rod can be released.

[0013] As Figures 1-10 shown, the specific implementation method is: The heat conduction rod is heated by the heating component, and then the needle tip can be heated. During heating, the heat of the heat conduction rod will be transferred to the heat conduction oil in the heat conduction oil storage cavity, and then the heat conduction oil is heated synchronously. When the needle tip is heated to a certain degree, the volume of the heat conduction oil expands and generates an upward thrust on the floating ring, so that the floating ring can act as a release component, and then the release component releases the limitation on the movement of the connecting rod, so that the driving component can drive the connecting rod to move downward quickly, so as to realize the rapid penetration of the needle tip out of the sheath and achieve rapid needle insertion. In addition, since the needle insertion is automatically started after the needle tip is heated to a certain temperature, it is possible to perform the needle insertion operation synchronously after the needle tip is heated to the preset degree without manual intervention, avoiding problems that affect the fire needle treatment effect caused by the overheating of the needle tip or the temperature of the needle tip not reaching the standard. In addition, by storing the needle tip in the sheath, the fear caused by the exposure of the needle tip to the patient is reduced.

[0014] In another preferred embodiment, the heating component includes:

[0015] An electric heating wire installed in the installation cavity opened in the handle;

[0016] A temperature detection module installed in the handle and used for detecting the temperature of the heat conduction rod;

[0017] The power supply control module is electrically connected to the temperature detection module and the heating wire through a cable, and is used to supply power to the heating wire.

[0018] After adopting the above scheme, the heating wire is powered by the power supply control module, so that the heating wire is energized to generate heat and heat the heat-conducting rod and the needle. In addition, the temperature of the heat-conducting rod is collected by the temperature detection module, and the power supply control module collects the signal of the temperature detection module. Then, the power supply parameters of the heating wire can be adjusted according to the temperature data value fed back by the temperature detection module, so that the heating wire can adjust the heating temperature of the heat-conducting rod, thereby realizing intelligent heating and temperature control of the needle.

[0019] In another preferred embodiment, the drive assembly includes:

[0020] A magnetic conductive ring is fixedly sleeved on one end of the connecting rod that passes through the sliding cavity;

[0021] The permanent magnet is fixedly connected to the sliding cavity and is located below the magnetic conductive ring. The permanent magnet has a magnetic attraction force on the magnetic conductive ring.

[0022] After adopting the above solution, the permanent magnet generates magnetic attraction on the magnetic ring, which enables the magnetic ring to drive the connecting rod to move downward quickly, so that the needle can quickly pass through the sheath, thereby achieving rapid insertion of the needle.

[0023] In another preferred embodiment, the release assembly comprises:

[0024] A fixing ring, fixedly installed in the sliding cavity, and the connecting rod freely penetrates the fixing ring;

[0025] The swing arm is hinged to the fixed ring and its two ends in the length direction respectively pass through the two ends of the fixed ring. The end surface of the fixed ring is provided with a clearance groove for the swing arm to swing freely through. The upper end of the swing arm is provided with a horizontally bent limit arm. The upper end of the connecting rod is provided with an annular groove. The end of the limit arm away from the swing arm is engaged with the annular groove. The lower end of the swing arm is in contact with the upper end surface of the floating ring.

[0026] The straightening unit is used to drive the swing arm from its natural state to a vertical state.

[0027] After adopting the above solution, when the heat-conducting oil expands in volume after being heated and can continuously push the floating ring to move upward, when the floating ring moves upward, it will exert a force on the lower end of the swing arm, causing the lower end of the swing arm to swing towards the radially inner direction of the handle, and further causing the upper end of the swing arm to swing in the opposite direction, and causing the limiting arm to disengage from the engagement state with the annular card slot, that is, to release the restriction on the movement of the connecting rod, so that the connecting rod can move, and thus the needle insertion operation can be performed. At the same time, the alignment unit can drive the swing arm to be in a vertical state in the natural state, so that the limiting arm can be engaged in the annular card slot and restrict the movement of the connecting rod, so that the connecting rod will not move during the heating process of the heat-conducting rod and avoid accidental needle insertion of the needle.

[0028] In another preferred embodiment, the alignment unit includes:

[0029] A stop ring, fixedly sleeved on the upper end of the swing arm and located above the fixed ring;

[0030] An alignment spring, sleeved on the swing arm, and the two ends of its elastic force direction elastically abut against the stop ring and the fixed ring respectively.

[0031] After adopting the above solution, when the swing arm swings along the hinge joint with the fixed ring, the alignment spring is synchronously elastically bent. When the floating ring moves downward and resets, the elastic bending of the alignment spring itself recovers and returns to a vertical state, and then can drive the swing arm to swing to a vertical state, realizing the reset swing of the swing arm, so that the limiting arm can be engaged in the annular card slot.

[0032] In another preferred embodiment, a return spring is sleeved on the connecting rod, and the two ends of the elastic force direction of the return spring elastically abut against the fixed ring and the floating ring respectively.

[0033] After adopting the above solution, by setting the return spring, when the floating ring moves upward, it can compress the return spring, and then the return spring accumulates elastic potential energy. When the temperature of the heat-conducting oil drops and the volume shrinks, the return spring can quickly drive the floating ring to move downward and reset.

[0034] In another preferred embodiment, an inclined section is provided at the lower end of the swing arm. The length direction of the inclined section forms an angle with the axial direction of the floating ring, and the minimum angle is an acute angle. A roller is rotatably connected to the lower end of the inclined section, and the roller is in rolling contact with the upper end surface of the floating ring.

[0035] After adopting the above solution, by setting the roller to be in rolling contact with the upper end surface of the floating ring, when the floating ring moves upward, it can drive the swing arm to swing more smoothly. In addition, the lower end of the inclined section extends towards the radially inner side of the handle, so that the swing arm can swing quickly when the floating ring moves upward, and then the limiting arm can disengage from the engagement state with the annular card slot more smoothly.

[0036] In another preferred embodiment, a pull ring is provided at one end of the connecting rod passing through the handle.

[0037] After adopting the above solution, by providing a pull ring, the needle can be retracted into the sheath by pulling the connecting rod toward the outside of the handle.

[0038] Technical effects and advantages of the present invention:

[0039] 1. The present invention is provided with a driving component, a heating component and a releasing component. The heating component heats the heat-conducting rod, thereby heating the needle. During heating, the heat of the heat-conducting rod is transferred to the heat-conducting oil in the heat-conducting oil storage chamber, thereby synchronously heating the heat-conducting oil. When the needle is heated to a certain degree, the volume of the heat-conducting oil expands and generates an upward thrust on the floating ring, so that the floating ring can act as a releasing component, thereby causing the releasing component to release the movement restriction of the connecting rod, thereby enabling the driving component to drive the connecting rod to move downward rapidly, thereby realizing the rapid penetration of the needle out of the sheath and rapid needle insertion. In addition, since the needle insertion is automatically started after the needle is heated to a certain temperature, the needle can be inserted synchronously after the needle is heated to a preset degree without human intervention, thereby avoiding the problem of overheating of the needle or the needle temperature not meeting the standard, which affects the effect of fire needle treatment.

[0040] 2. The present invention is provided with a heating wire, a temperature detection module, and a power supply control module. The power supply control module supplies power to the heating wire, thereby causing the heating wire to generate heat and heat the heat-conducting rod and the needle. In addition, the temperature detection module collects the temperature of the heat-conducting rod, and the power supply control module collects the signal from the temperature detection module. The power supply parameters of the heating wire can be adjusted according to the temperature data value fed back by the temperature detection module, thereby enabling the heating wire to adjust the heating temperature of the heat-conducting rod, thereby realizing intelligent heating and temperature control of the needle.

[0041] 3. The present invention provides a fixed ring, a swing arm, and a swaying unit. When the heat transfer oil is heated, the volume expands and the floating ring is continuously pushed upward. When the floating ring moves upward, a force is exerted on the lower end of the swing arm, causing the lower end of the swing arm to swing toward the radial inner side of the handle, thereby causing the upper end of the swing arm to swing in the opposite direction and causing the limit arm to disengage from the engagement state with the annular groove, that is, contacting the restriction on the movement of the connecting rod, thereby allowing the connecting rod to move, thereby enabling the needle insertion operation. At the same time, the swaying unit can drive the swing arm to a vertical state in its natural state, so that the limit arm can be engaged in the annular groove and limit the movement of the connecting rod. In this way, the connecting rod will not move during the heating process of the heat transfer rod, thereby preventing the needle from being inserted accidentally.

[0042] 4. The present invention is provided with a reset spring, so that when the floating ring moves upward, it can compress the reset spring, thereby enabling the reset spring to accumulate elastic potential energy. When the temperature of the heat-conducting oil drops and its volume shrinks, the reset spring can quickly drive the floating ring to move downward and reset. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0054] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0055] As Figures 1-10 shown, the present invention provides a fire needle device with intelligent temperature control and rapid needle insertion, including a handle 3. The outer surface of the handle 3 is provided with a rubber layer, so that the staff can hold the handle 3 by hand. In addition, a sheath 6 coaxial with the handle 3 is provided at one axial end of the handle 3. A connecting rod 2 is coaxially inserted through the other end of the handle 3 away from the sheath 6. The connecting rod 2 can slide freely on the handle 3. In addition, a heat-conducting rod 18 is coaxially fixed to the end of the connecting rod 2 inserted into the handle 3. A needle 22 is coaxially fixed to the end of the heat-conducting rod 18 away from the connecting rod 2. A perforation 21 for the heat-conducting rod 18 to pass through freely is provided on the sheath 6. An installation cavity 13 is coaxially opened at one end of the handle 3 adjacent to the sheath 6. A spiral heating wire 14 is arranged in the installation cavity 13. The heat-conducting rod is inserted into the heating wire 14. In addition, both ends of the heating wire 14 are electrically connected to a power supply control module 33 through cables. In this way, the power supply control module 33 energizes the heating wire 14, so that the heating wire 14 can generate heat after being energized, and heat the heat-conducting rod and the needle. After the needle is heated to a predetermined degree, it passes through the sheath, so that the needle can perform needle insertion;

[0056] Please refer with emphasis to Figure 10, since the heating wire 14 is energized, the temperatures of the heat conducting rod and the needle tip will continue to rise, which may cause the heating temperature of the needle tip to exceed the predetermined range. Therefore, in this embodiment, a temperature detection module 32 is installed on the handle 3. The probe of the temperature detection module 32 contacts the heat conducting rod 18 and can collect the temperature data of the heat conducting rod 18. Then, the temperature detection module 32 feeds back the temperature data to the power supply control module 33 through a cable or a wireless transmission module. In this way, the power supply control module 33 can collect the temperature data in the temperature detection module 32 in real time, and then determine the heating temperature of the heat conducting rod 18. According to the difference between the heating temperature of the heat conducting rod 18 and the predetermined heating temperature, the power supply control module can adjust the current supplied to the heating wire 14, so that the heating wire 14 adjusts the temperature according to the real-time heating temperature of the heat conducting rod 18, realizing the constant temperature control of the needle tip, and avoiding the poor fire needle treatment effect caused by the needle tip temperature exceeding the predetermined range during treatment;

[0057] Please refer specifically to Figure 2 , 3, 6, 7, 8, and 9. Since the needle insertion of the needle 22 needs to be adapted to its heating temperature, that is, the needle can only be inserted after the needle 22 is heated to a predetermined degree. Therefore, in this embodiment, a sliding cavity 7 is coaxially opened in the handle 3. A floating ring 11 is engaged in the sliding cavity 7. The floating ring 11 forms a sliding fit with the sliding cavity 7 and can slide up and down freely. A heat-conducting oil storage cavity 12 is formed between the floating ring 11 and the inner wall of the sliding cavity 7 adjacent to the sheath 6. Heat-conducting oil is stored in the heat-conducting oil storage cavity 12. The connecting rod 2 slidably penetrates the floating ring 11. A magnetic conductive ring 8 is fixedly sleeved on the end of the connecting rod 2 that penetrates into the sliding cavity 7. A fixed ring 9 is coaxially and fixedly installed in the sliding cavity 7. The connecting rod 2 freely penetrates the fixed ring 9. In addition, a permanent magnet 27 is fixedly connected to the upper end surface of the fixed ring 9. The permanent magnet 27 is located below the magnetic conductive ring 8. The permanent magnet 27 has a magnetic attraction force on the magnetic conductive ring 8. A swing arm 24 is hinged on the fixed ring 9, and both ends of the swing arm 24 in the length direction penetrate through both ends of the fixed ring 9. An avoidance groove 31 for the free passage of the swing of the swing arm 24 is opened on the end surface of the fixed ring 9. A limiting arm 23 with a horizontal bend is provided at the upper end of the swing arm 24. An annular clamping groove 28 is opened at the upper end of the connecting rod 2. The end of the limiting arm 23 away from the swing arm 24 is engaged in the annular clamping groove 28. The lower end of the swing arm 24 is in contact connection with the upper end surface of the floating ring 11. When heating the heat-conducting rod 18 and the needle, the heat-conducting oil is heated synchronously. When the heat-conducting oil is heated, its volume expands and can continuously push the floating ring upward. When the floating ring moves upward, it will generate a force on the lower end of the swing arm, causing the lower end of the swing arm to swing towards the radially inner direction of the handle, and then causing the upper end of the swing arm to swing in the opposite direction, and causing the limiting arm to disengage from the engaged state with the annular clamping groove, that is, releasing the restriction on the movement of the connecting rod. At this time, the permanent magnet generates a magnetic attraction force on the magnetic conductive ring, so that the magnetic conductive ring can drive the connecting rod to move downward quickly, so that the needle quickly penetrates through the sheath, and thus realizes the quick needle insertion of the needle. Since only when the temperatures of the needle and the heat-conducting rod reach a predetermined degree can the floating ring move upward in place, and then the swing arm swings to the state where the limiting arm disengages from the engaged state with the annular clamping groove, enabling the connecting rod to move. In this way, the needle can perform self-insertion after being heated to a predetermined degree without manual interference, so the operation is more convenient;

[0058] Please refer specifically to Figure 2 , 3And 7, in the natural state, the swing arm 24 may swing by itself and cause the limit arm 23 to be out of the engagement state with the annular groove 28, thereby making it impossible to restrict the movement of the connecting rod 2. Therefore, in this embodiment, a stop ring 25 is fixedly sleeved on the upper end of the swing arm 24, and the stop ring 25 is located above the fixed ring 9. In addition, a straightening spring 26 is wound around the swing arm 24, and the two ends of the straightening spring 26 in the elastic direction elastically press against the stop ring 25 and the fixed ring 9 respectively. When the swing arm swings along the hinge with the fixed ring, the straightening spring is synchronously elastically bent. When the floating ring moves down and resets, the straightening spring itself elastically bends and recovers to a vertical state, thereby driving the swing arm to swing to a vertical state, realizing the reset swing of the swing arm, so that the limit arm can be engaged in the annular groove;

[0059] Please refer to Figure 2 In the natural state or before the fire needle is inserted, the floating ring 11 may not be in its original position, thereby exerting a force on the swing arm 24, causing the swing arm 24 to swing, and causing the limit arm 23 to be unable to accurately engage in the annular groove 28, thereby affecting the movement restriction of the connecting rod 2. Therefore, in this embodiment, a return spring 10 is wound around the connecting rod 2, and the two ends of the return spring 10 in the elastic direction elastically press against the fixed ring 9 and the floating ring 11 respectively. When the floating ring moves upward, it can compress the return spring, thereby causing the return spring to accumulate elastic potential energy, so that after the temperature of the heat transfer oil drops and the volume shrinks, the return spring can quickly drive the floating ring to move downward and reset.

[0060] Please refer to Figure 2 、 7, since the lower end of the swing arm 24 directly contacts the upper end surface of the floating ring 11, when the floating ring 11 moves upward and there is relative sliding between the lower end of the swing arm 24 and the floating ring 11, the wear amount of the contact surface between the two is relatively large. At the same time, the swing arm 24 may not be able to swing quickly, that is, the lower end of the swing arm 24 cannot swing quickly towards the radially inner direction of the handle 3, resulting in the limit arm 23 being unable to disengage from the engaged state with the annular card slot 28. Therefore, in this embodiment, an inclined section 29 is provided at the lower end of the swing arm 24. The length direction of the inclined section 29 forms an angle with the axis of the floating ring 11, and the minimum angle is an acute angle. A roller 30 is rotatably connected to the lower end of the inclined section 29, and the roller 30 is in rolling contact with the upper end surface of the floating ring 11. When the floating ring moves upward, the upper end surface of the floating ring can exert a force on the roller 30. Due to the setting of the inclined section, the roller 30 will swing towards the radially inner side of the handle 3, and thus can drive the swing arm to swing more smoothly. In addition, the lower end of the inclined section extends towards the radially inner side of the handle, so that the swing arm can swing quickly when the floating ring moves upward, and thus the limit arm can disengage from the engaged state with the annular card slot more smoothly. At the same time, the setting of the roller reduces the wear amount of the contact surface between the swing arm and the upper end surface of the floating ring. In addition, a pull ring 1 is provided at one end of the connecting rod 2 that passes through the handle 3. Thus, by pulling the connecting rod towards the outer side of the handle, the needle can be retracted into the sheath;

[0061] Please refer specifically to Figure 1 , 2, 5, and 6. Since the puncture site needs to be disinfected with alcohol after the use of the needle 22 for the convenience of the next use, and since the needle 22 is stored in the through hole 21 of the sheath 6 after the needle insertion is completed, it is inconvenient to disinfect the needle 22 with alcohol. Therefore, in this embodiment, an annular communication cavity 20 is coaxially provided in the sheath 6. In addition, a plurality of capillary liquid outlet holes 19 communicating with the communication cavity 20 are provided on the hole wall of the through hole 21. After the needle insertion is completed, the heat conducting rod 18 moves towards the outer side of the sheath 6 and can just block the capillary liquid outlet holes 19. In addition, a connecting pipe 4 is commonly connected to the upper end of the handle 3 and the sheath 6. The two ends of the connecting pipe 4 communicate with the sliding cavity 7 and the communication cavity 20 respectively. A storage seat 5 is connected to the connecting pipe 4. The inside of the storage seat 5 is hollow and a piston 17 is slidably engaged inside. The piston 17 can freely slide up and down in the storage seat 5, and the connecting pipe 4 is communicated with the inside of the storage seat 5. A liquid storage cavity 15 is formed between the piston 17 and the inner wall of the lower side of the storage seat 5. A telescopic spring 16 is vertically installed in the liquid storage cavity 15. The telescopic spring 16 has an upward elastic abutting force on the piston 17. In addition, disinfected alcohol is stored in the liquid storage cavity 15. When the floating ring 11 moves upwards, the air in the upper space of the sliding cavity 7 will be compressed, and then the air will enter the storage seat 5 and generate a downward thrust on the piston 17, so that the piston 17 can squeeze the disinfected alcohol in the liquid storage cavity 15, and then squeeze the disinfected alcohol into the communication cavity 20 and spray it onto the needle 22 retracted into the through hole 21 through the plurality of capillary liquid outlet holes 19, so that the disinfected alcohol can disinfect the needle 22. In addition, since the heat conducting rod moves downwards to close the capillary liquid outlet holes 19 during needle insertion, the disinfected alcohol will not spray out from the capillary liquid outlet holes 19 when the needle 22 is performing needle insertion and puncture. When the needle 22 is completely inserted and retracted into the through hole, at this time, the disinfected alcohol will be sprayed out from the capillary liquid outlet holes into the through hole under the extrusion of the piston, so as to disinfect the needle. Therefore, the operation of disinfecting the needle with disinfected alcohol does not require manual operation and does not require the needle to be exposed outside the sheath for disinfection operation, which saves time and effort. When the floating ring 11 moves downwards, through the elastic abutting of the telescopic spring 16, the piston moves upwards to reset, preventing the disinfected alcohol from overflowing from the capillary liquid outlet holes by itself.
