Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary appliances, and particularly relates to a fire needle treatment device based on precise positioning and its usage method. Background Art

[0003] Currently, during clinical treatment, the main method is to manually insert the fire needle. The traditional manual insertion of the fire needle has the following problems: The fire needle is very thin. After being heated red, the optimal operation time window during the process of transferring it from the alcohol lamp to the skin is only 1 - 2 seconds. During these 1 - 2 seconds, the operator needs to quickly and accurately find the point manually, insert the needle into the skin quickly, and at the same time control the depth of needle insertion. This requires very high skills for the acupuncture operator. It is very easy to have a deviation in the needle insertion point of the fire needle, which requires repeated needle insertion, increasing the patient's pain and affecting the treatment efficiency. If the depth is too shallow, the treatment expectation cannot be achieved. If the depth is too deep, it will prolong the healing time of the patient's acupuncture wound and may also not achieve the treatment expectation.

[0004] To solve the problems existing in the above - mentioned manual insertion of the fire needle, some existing manufacturers have designed a fire needle device. For example, the Chinese patent "A Fire Needle Device" with the publication number CN113397968A discloses a fire needle device, which includes a housing, 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. In this invention, 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, causing the needle tool to pop 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 adjusted by adjusting the position of the needle sleeve. The pop - out of the fire needle tool is caused by the second push block receiving an external thrust and then popping out after being transmitted through the gear. However, the existing fire needle device has the following deficiencies during use:

[0005] 1) The needle tool of the existing fire needle device is hidden in the needle sleeve and requires its supporting special long - shaped needle tool, with poor compatibility. Some multi - needle needle tools cannot be used, and the treatment method is relatively single;

[0006] 2) The existing fire needle device sets the heating tube at the front end of the needle sleeve. The high - temperature heating tube cannot be positioned closely to the skin. If the fire needle pops out short, there is also a problem that the heating tube is too close to the skin, resulting in burns;

[0007] 3) The puncture point is positioned through the needle sleeve, and only a rough regional positioning can be achieved. The acupoint positioning for needle insertion still depends on the operator's experience, with a large degree of uncertainty. Summary of the Invention

[0008] The object of the present invention is to overcome the deficiencies of the prior art.

The height of the sliding groove gradually expands from the right end to the left end. An I-shaped slider is formed at the bottom end of the laser emitter base, which is detachably inserted into the sliding grooves of the two groups of emitter brackets through the I-shaped slider at the bottom. The laser emitter base can finely adjust the laser alignment point of the laser emitter up, down, left, and right.

[0012] Furthermore, the support measuring structure includes a support measuring ruler and an insulating foot pad, the support measuring ruler is installed on one side of the cam bin, the insulating foot pad is located at one end of the support measuring ruler and is connected to it, and the installation location of the support measuring ruler and the cam bin is also provided with a measuring dial that matches the scale reading of the support measuring ruler.

[0013] Furthermore, the driving structure includes a motor fixing seat, a DC motor, and a cam. The motor fixing seat is fixed to the upper accommodating chamber of the cam bin, the DC motor is installed on the motor fixing seat, the motor shaft of the DC motor is connected to the cam, and the driving structure is connected to the fire needle clamping adjustment structure through the cam.

[0014] Furthermore, the fire needle clamping and adjustment structure includes a fire needle, a clamping mechanism, and a fire needle depth adjustment mechanism. The clamping mechanism is located at one end of the fire needle and connected to it. One end of the fire needle depth adjustment mechanism is connected to the fire needle through the clamping mechanism, and the other end of the fire needle depth adjustment mechanism is connected to the cam of the driving structure.

[0015] Furthermore, the fire needle depth adjustment mechanism includes a pushing connecting rod, an adjusting drive rod, and a positioning bore head. The positioning bore head is installed in front of the cam bin, one end of the adjusting drive rod is connected to the cam of the driving structure, the other end of the adjusting drive rod passes through the positioning bore head and is connected to one end of the pushing connecting rod, one end of the pushing connecting rod is connected to the other end of the adjusting drive rod, and the other end of the pushing connecting rod is fixed with an internal connecting joint, and the pushing connecting rod is connected to the clamping mechanism through the internal connecting joint to realize the connection between the fire needle depth adjustment mechanism and the fire needle.

[0016] Furthermore, the clamping mechanism includes a fastening nut, a fire needle clamp, and an external connecting joint. The fire needle clamp is a split bolt with a hollow channel inside. The fire needle passes through the hollow channel inside the fire needle clamp. The fastening nut is threadedly connected to the right end of the fire needle clamp.

[0018] On the other hand, the present invention also provides a method for using a fire needle treatment device based on precise positioning, the method comprising the following steps:

[0019] Step 1) Initially fix the needle: fix the fire needle on the fire needle clamping and adjusting structure, and when the power switch is not turned on, the fire needle treatment device is not powered and can move freely forward and backward;

[0020] Step 2) The fire needle is manually extended to the farthest end: The fire needle is manually extended to the farthest end. At this time, after the fire needle treatment device is powered on, the cam of the driving structure can drive the fire needle to the farthest end of its travel;

[0021] Step 3) Align the insulating foot pad of the support measurement structure with the needle tip: loosen the fastening bolts, then move the support measurement ruler, translate the insulating foot pad of the support measurement ruler to a position flush with the farthest end of the fire needle tip, and read the scale of the support measurement ruler at this time;

[0022] Step 4) Adjust the depth of the fire needle: set the fire needle to penetrate the patient's skin H mm for this operation, then move the support measuring ruler in the support measuring structure back to H scale, tighten the fastening bolts, and fix the relative distance H between the insulation foot pad and the farthest end of the fire needle;

[0023] Step 5) Start the motor to align the laser with the acupuncture point: When the operator is performing acupuncture, turn on the power switch. At this time, the laser transmitter will emit a laser to locate the expected acupuncture point. The laser transmitter base can be used to fine-tune the laser alignment point of the laser transmitter up, down, left and right. The speed of the DC motor can be adjusted using the speed knob. After the fire needle is heated and red by an external heat source, the insulated foot pad at one end of the support measuring ruler is used to press against the patient's skin as a support point and reference height control for the fire needle operation. Pressing the trigger can start the DC motor and drive the fire needle to move back and forth in a straight line. The farthest end of the fire needle tip extends H mm relative to the insulated foot pad, which means the fire needle is inserted into the patient's skin to a depth of H mm.

[0024] Compared with the prior art, the technical solution of the present invention has at least the following beneficial effects:

[0025] 1) The fire needle treatment device of the present invention includes a fire needle clamping adjustment structure, a laser positioning structure, a holding structure, a support and measurement structure, a driving structure, and a power supply and control structure. The driving structure and the power supply and control structure are respectively installed on the upper and lower sides of the holding structure. The laser positioning structure is installed on the upper end of the holding structure, and the support and measurement structure is installed on one side of the holding structure. The fire needle clamping adjustment structure is installed on the front end of the holding structure. The driving structure is connected to the fire needle clamping adjustment to drive the fire needle clamping adjustment structure to perform linear reciprocating motion. The fire needle treatment device of the present invention cooperates with the driving structure, the laser positioning structure, and the support and measurement structure to enable the fire needle treatment device to visually, accurately, and stably control the acupuncture position and acupuncture depth, significantly reducing the operational difficulty of fire needle treatment, improving the accuracy of treatment, and solving technical problems such as the difficulty in controlling the acupuncture depth of traditional fire needle treatment instruments, the inability to accurately and visualize the acupuncture position, and the slow electric heating of the fire needle.

[0026] 2) The laser positioning structure provided by the present invention includes a laser emitter base, two sets of emitter brackets, and a laser emitter. The two sets of emitter brackets are symmetrically fixed at the upper end of the cam chamber of the holding structure. Each set of emitter brackets is provided with a sliding groove. An I-shaped slider matching the sliding groove is formed at the bottom end of the laser emitter base. The laser emitter base is detachably inserted into the sliding grooves of the two sets of emitter brackets through the I-shaped slider at the bottom. By emitting laser light, the laser emitter can provide the most direct and accurate laser point indication of the needle insertion target position for the operator, helping the operator quickly visually locate, reducing the repeated needle insertions caused by the needle being inserted in the wrong position or deflected due to technical or experience reasons during manual acupuncture, greatly reducing the operation threshold and operation speed of the operator, and effectively reducing the pain of the patient.

[0027] 3) The support and measurement structure provided by the present invention includes a support measurement ruler, an adiabatic foot pad, and a fastening bolt. A strip-shaped groove is provided in the middle of the support measurement ruler. The fastening bolt is slidably inserted through the strip-shaped groove of the support measurement ruler. The support measurement ruler is installed on one side of the cam chamber through the cooperation of the fastening bolt and the strip-shaped groove. The adiabatic foot pad is located at one end of the support measurement ruler and is connected thereto. A measurement scale disk matching the scale reading of the support measurement ruler is also provided at the installation position of the support measurement ruler and the cam chamber. The support and measurement structure of the present invention makes the acupuncture operation have high certainty and high stability in the needle insertion depth. The support measurement ruler has the functions of measuring the depth before needle insertion and supporting the reference height during needle insertion. Before acupuncture, the scale of the support measurement ruler is matched with the measurement scale disk to quickly and accurately adjust the extended length of the support measurement ruler, thereby controlling the acupuncture depth of the fire needle. Its extended length serves as the reference height. During acupuncture, the support measurement ruler supports on the patient's skin, avoiding positioning errors caused by the fire needle being suspended and the hand shaking. The support measurement ruler plays a role in stabilizing the reference height. Therefore, by presetting the length of the fire needle exceeding the support measurement ruler, the depth of each time the fire needle penetrates the skin can be stably controlled.

[0028] 4) The fire needle clamping and adjusting structure provided by the present invention includes a fire needle, a clamping mechanism, and a fire needle depth adjusting mechanism. The clamping mechanism is located at one end of the fire needle and is connected thereto. One end of the fire needle depth adjusting mechanism is connected to the fire needle through the clamping mechanism, and the other end of the fire needle depth adjusting mechanism is connected to the cam of the driving structure. The present invention facilitates the disassembly and installation of the fire needle through the clamping mechanism. Most of the fire needles used in medical institutions can be installed on the fire needle treatment device of the present invention, without the need for special fire needles, greatly increasing the scope of application, facilitating the operator to replace different fire needle types at any time, quickly replacing fire needles with different effects or cleaning the fire needles.

The DC motor 52 is fixed to the upper accommodation chamber 321 of the cam chamber 32 through the motor fixing seat 51. The DC motor 52 is started to rotate, thereby driving the cam 53 to rotate. The power switch 36 provided in the present invention has two working states: on and off. The fire needle treatment device can be conveniently turned on and off through the power switch 36. The speed adjustment knob 35 provided is a flat knob that can be rotated clockwise and counterclockwise, mainly used to adjust the rotation speed of the DC motor 52 in the driving structure 5, and further adjust the needle insertion speed and number of times of the fire needle treatment.The fire needle treatment device of the present invention can fix different types of fire needles 11 through the fire needle clamping and adjusting structure, and visually locate the treatment position through the laser positioning structure 2, so that the operation of the fire needle 11 has a high target point for needle insertion, improving the visibility and high precision of the needle insertion of the fire needle 11.

Specifically, in implementation, a connecting shaft 135 is provided at the connection between the adjusting driving rod 133 and the cam 53. One end of the adjusting driving rod 133 is connected to the cam 53 through the connecting shaft 135.
