Abstract
Description
Technical Field
[0001] The invention relates to the field of medical equipment, in particular to an automatic fire needle. Background Art
[0002] Abscesses on the surface of the body refer to the accumulation of pus in the surface tissue, causing local redness, swelling, pain, tenderness, temperature rise and fluctuation or systemic symptoms. They are mostly caused by pathogen infection, especially Staphylococcus aureus. If abscesses are not treated promptly and effectively, they may cause bacteremia, systemic inflammatory response syndrome and even multiple organ dysfunction. Currently, conventional treatment options for abscesses on the surface of the body mainly rely on percutaneous puncture aspiration, small incision catheter drainage and surgical incision and drainage.
[0003] However, these methods each have their own advantages and disadvantages: percutaneous aspiration causes minimal trauma and has certain advantages for smaller abscesses, but it is easy to cause poor and incomplete drainage; the surgery causes great trauma and easily forms scars, affecting the appearance and organ function; catheter drainage can take into account both efficacy and appearance, but the indwelling drainage tube is easy to fall off, and postoperative care is cumbersome, increasing the physical and mental burden on patients.
[0004] In order to seek a more minimally invasive and efficient treatment method, traditional Chinese medicine fire needle therapy has been introduced into the treatment of surface abscesses. Fire needle therapy uses high-temperature burning needles to form a scab channel at the abscess site, achieving the dual effects of debridement and drainage. Compared with traditional surgery, fire needle therapy has the advantages of small wounds, smooth drainage, fast recovery, small scars, and simple care, which greatly reduces the pain and inconvenience of patients.
[0005] However, the efficacy of fire needle therapy is highly dependent on the precise control of parameters such as temperature, speed, depth, angle and dwell time during the operation. At present, the control of these parameters mainly depends on the doctor's personal experience and touch, resulting in individual differences in treatment effects, which are difficult to standardize and quantify.
[0006] Therefore, how to accurately control the operating parameters of fire needle therapy and improve the stability and repeatability of treatment has become an urgent problem to be solved. Summary of the invention

[0042] See also Figure 1 The figure shows a schematic diagram of the structure of an automatic fire needle of the present invention.
[0043] See also Figures 1 to 4 An automatic fire needle comprises a shell 100 and a fire needle assembly installed in the shell 100. When in use, the fire needle assembly can be driven to extend out of the shell 100 for fire needle treatment.
[0044] The housing 100 can be operated by hand, or placed on an operating plane and supported by the operating surface. Usually, the operator holds the housing 100 on one side of the patient to treat the patient.
[0045] When the housing 100 described in the present invention is placed on an operating plane, the housing 100 generally has a flat bottom surface 105, or a bottom surface 105 that is close to a flat state. Generally, when in use, the bottom surface 105 of the housing 100 can be placed on the operating surface, and the inclination angle of the bottom surface 105 can be adjusted by an external three-axis bracket or an omnidirectional pan-tilt head. Alternatively, in some other embodiments, the bottom surface 105 of the housing 100 can also be provided with supporting feet.
[0046] Preferably, the housing 100 is a commonly used square housing 100, for example, the housing 100 is a rectangular parallelepiped, the interior of the housing 100 is hollow, and the bottom surface 105 is a plane. Alternatively, in some other embodiments, the housing 100 may also be a structure of other shapes, such as a cube, a cylindrical structure, etc.
[0047] Alternatively, in some other embodiments, the housing 100 may not be placed on an operating surface for use, but may be installed on other devices and used in conjunction with other devices, which is not limited here.
[0048] The fire needle assembly of the present invention generally includes a fire needle 210, which is used to quickly pierce the affected part of the patient to treat the disease. The fire needle assembly of the present invention can be used to treat abscesses on the body surface.
[0049] Preferably, the fire needle 210 is generally made of a thicker stainless steel round tube, such as a round tube or a stainless steel tube with a diameter of 3-6 mm.
[0050] The fire needle assembly also includes a guide needle 230, which is used to navigate the puncture of the fire needle 210. Before the fire needle 210 is inserted, the doctor first punctures the guide needle 230 to the lesion point to determine the puncture site, and then quickly inserts the fire needle 210 for treatment, so that the positioning of the fire needle 210 is more accurate during treatment.
[0051] Preferably, the diameter of the fire needle 210 is slightly larger than the diameter of the guide needle 230 so as to surround the guide needle 230 .
[0052] Furthermore, the guide needle 230 and the fire needle 210 have the same moving direction, and the guide needle 230 can move relative to the fire needle 210. When in use, the guide needle 230 can move to a predetermined position and be positioned, and the fire needle 210 can move to a predetermined position according to the moving direction of the guide needle 230, so that the guide needle 230 is used to navigate the puncture of the fire needle 210.
[0053] Preferably, the fire needle 210 and the guide needle 230 are parallel to each other, and the guide needle 230 is at least partially located in the fire needle 210 and can move in the fire needle 210. Specifically, in this embodiment, a through hole 220 is provided in the middle of the fire needle 210, and the through hole 220 penetrates the fire needle 210 along the length direction of the fire needle 210, which allows the guide needle 230 to pass smoothly, and allows the guide needle 230 to move therein, so that the guide needle 230 can move relative to the fire needle 210.
[0054] It is understandable that in some other embodiments, the guide needle 230 may not be set inside the fire needle 210, but may be set on one side of the fire needle 210, or surround the fire needle 210 in the form of an outer sleeve, as long as it can be used to guide the fire needle 210 to accurately insert into the patient's affected area, and there is no limitation here.
[0055] Both the fire needle 210 and the guide needle 230 can move within the shell 100 and are used to extend or be stored within the shell 100 for guidance and treatment respectively, and to prevent the fire needle 210 and the guide needle 230 from being exposed to the outside and accidentally injuring others or causing damage to the fire needle 210 and the guide needle 230.
[0056] refer to Figure 1 A first slider 101 is provided in the shell 100, and a first base 102 is movably mounted on the first slider 101. The fire needle 210 is mounted on the first base 102. When the first base 102 moves from the first slider 101, the fire needle 210 can move along with the first slider 101, so that the fire needle 210 can be extended or retracted in the shell 100.
[0057] Furthermore, the shell 100 is provided with a second slider 103, on which a second base 104 is movably mounted, and a guide needle 230 is mounted on the second base 104. When the second base 104 moves from the second slider 103, the guide needle 230 can move on the second slider 103 along with the second base 104, so that the guide needle 230 can be extended or retracted in the shell 100.
[0058] Preferably, the first slider 101 and the second slider 103 are arranged in parallel in the shell 100, so that the fire needle 210 and the guide needle 230 installed on the first base 102 and the second base 104 can move in parallel in the same direction, so that the guide needle 230 can guide the fire needle 210.
[0059] Preferably, the first slider 101 and the second slider 103 are arranged on opposite sides of the housing 100 and are arranged opposite to each other in the housing 100. When the fire needle 210 and the guide needle 230 are respectively mounted on the first base 102 and the second base 104, the guide needle 230 can extend into the fire needle 210 and can move relative to the fire needle 210. Specifically, in this embodiment, the first slider 101 is arranged on the inner side of the top surface of the housing 100, and the second slider 103 is arranged on the bottom surface 105 of the housing 100. In the housing 100, the first slider 101 and the second slider 103 are arranged opposite to each other, and the fire needle 210 and the guide needle 230 thereon can be simultaneously located in the middle of the height of the housing 100. The fire needle 210 and the guide needle 230 overlap in the height direction, and the guide needle 230 can extend into the fire needle 210 and move.
[0060] Preferably, a sliding groove is also provided on the side of the fire needle 210 , and the sliding groove is provided along the moving direction of the guide needle, so that the second base 104 can pass through the fire needle 210 through the sliding groove to connect to the guide needle 230 inside the fire needle 210 , and can push the guide needle 230 to move relative to the fire needle 210 .
[0061] Preferably, the housing 100 is provided with an extension hole (not shown) on one side, and the fire needle 210 and the guide needle 230 are installed in the housing 100, and the end of one end thereof is facing the extension hole, and can be extended or retracted from the extension hole. Specifically, in this embodiment, the extension hole is provided on the right side of the rectangular housing 100, and the fire needle 210 and the guide needle 230 can move along the length direction thereof in the housing 100, and are used to extend or retract on the right side of the housing 100.
[0062] Preferably, the extension hole may be a round hole or a square hole, the diameter of which is larger than the diameters of the fire needle 210 and the guide needle 230, so that the fire needle 210 and the guide needle 230 can be extended or retracted therefrom.
[0063] Preferably, the end of the guide needle 230 extending out of the housing 100 is a pointed end, so that the guide needle 230 can be inserted into the patient's body.
[0064] It is understandable that the fire needle 210 can also be implemented as a tubular or tapered end at the end extending out of the shell 100, so that the fire needle 210 can be inserted into the patient's body more conveniently.
[0065] It also includes a heating structure 300, which can be used to heat the fire needle 210, so that the fire needle 210 can be inserted into the patient's affected area after being heated. The fire needle 210 is electrocauterized at high temperature, so that the affected area tissue can be denatured and carbonized when the fire needle 210 is inserted, and a tissue hardening channel can be formed at the insertion site, thereby achieving the effect of continuous drainage of the affected area.
[0066] Specifically, the heating structure 300 is a ceramic heater disposed in the housing 100 , which can be used to heat the fire needle 210 .
[0067] Preferably, the ceramic heater is inside the housing 100 and is sleeved on the outside of the fire needle 210 , and a channel is provided therein for the fire needle 210 to pass through, so that the movement of the fire needle 210 is not affected during heating.
[0068] Preferably, the ceramic heater is located at the front side of the base in the moving direction of the fire needle 210 .
[0069] Preferably, the heating temperature of the ceramic heater on the fire needle 210 is 100-800°C.
[0070] Preferably, the fire needle 210 is a hollow fire needle with a pointed end for tissue puncture, and is made of 316L stainless steel that can withstand high temperatures and has biocompatibility, which is convenient for heating.
[0071] It also includes a braking device, which includes a first driving device connected to the first base 102 and a second driving device connected to the second base 104. The first driving device and the second driving device can respectively drive the first base 102 and the second base 104 to move, so that both the fire needle 210 and the guide needle 230 can move.
[0072] Specifically, the first driving device and the second driving device can both be linear motors, which are mainly responsible for controlling the stroke, speed and dwell time of the fire needle 210 and the guide needle 230. The fire needle 210 and the guide needle 230 are moved by the linear motors, and the speed, dwell time and stroke are precisely controlled, so that they can be quickly positioned to the patient's affected area.
[0073] Alternatively, in some other embodiments, the first drive device and the second drive device may both be stepper motors, or the first drive device may be a linear motor and the second drive device may be a stepper motor, or the first drive device may be a stepper motor and the second drive device may be a linear motor. As long as the precise displacement of the fire needle 210 and the guide needle 230 can be achieved, there is no limitation here.
[0074] Preferably, the guide needle 230 can also be moved by manually pushing a handle on the shell 100. For example, the second base can be configured as a handle that is at least partially located outside the shell 100. During operation, the doctor first manually pushes the guide needle 230 to allow the guide needle 230 to penetrate the designated position of the affected area.
[0075] It is understandable that when the second driving device is configured as a linear motor or a stepping motor, the second base 104 should be allowed to be pushed by forces other than the second driving device, so that the guide needle 230 can also be pushed by the handle.
[0076] Preferably, the second slider 103 is provided with a guide rail clamp. When the operator pushes the handle to drive the guide needle to the specified position, the second slider can be locked on the slide rail through the controller 600. This prevents the guide needle from sliding during the extension of the fire needle. After the fire needle reaches the specified position and the treatment time is preset, the controller 600 can feedback-control the guide rail clamp of the second slider 103 to release so that the second drive device can drive the second slider to retract.
[0077] It also includes a liquid storage box 400, which can be used to collect pus flowing out of the patient's affected area to prevent the splashed pus from entering the shell 100 and directly contaminating the core components in the shell 100.
[0078] Preferably, the liquid storage box 400 is arranged in the housing 100. Specifically, the liquid storage box 400 is a hollow polyhedron, the interior of which can be used to collect pus, and the liquid storage box 400 is provided with an air-avoiding hole 410 on the side. When the liquid storage box 400 is installed in the housing 100, the fire needle 210 passes through the air-avoiding hole 410 of the liquid storage box 400, so that the fire needle 210 passes through the liquid storage box 400, so that the liquid storage box 400 in the housing 100 will not affect the extension of the fire needle 210.
[0079] Preferably, the liquid storage box 400 is close to the extension hole in the housing 100, and the fire needle 210 passes through the liquid storage box 400 and then extends out of the housing 100 through the extension hole, so that when the fire needle 210 pierces the patient's affected part, the splashing pus will first flow into the liquid storage box 400, avoiding the splashing pus directly entering the housing 100 and contaminating the core components in the housing 100. For example, when the fire needle pierces the affected part obliquely upward, the pus flows along the fire needle 210 to the housing 100 and is first stored in the liquid storage box 400.
[0080] The liquid storage box 400 can also be disassembled in the housing 100. The liquid storage box 400 can be disassembled to clean the fire needle 210 and the guide needle 230, and the disassembled liquid storage box 400 can also be cleaned to prevent pus from contaminating the inside of the device. For example, a mounting groove (not shown) for mounting the liquid storage box 400 is provided in the housing 100, and the shape of the mounting groove is adapted to the shape of the liquid storage box 400. When the liquid storage box 400 is installed in the mounting groove, it is fixed, and the liquid storage box 400 can be taken out in the mounting groove for cleaning the liquid storage box 400.
[0081] It also includes a heat-insulating pad 500, which is used to pad between the patient and the shell 100 to prevent the fire needle 210 from scalding other parts of the patient.
[0082] Preferably, the thermal insulation pad 500 is arranged outside the housing 100. Specifically, the thermal insulation pad 500 is arranged outside the extension hole of the housing 100, and the thermal insulation pad 500 is also provided with a channel, which is opposite to the extension hole, so that the thermal insulation pad 500 surrounds the outer side of the fire needle 210 and the guide needle 230, does not affect the use of the fire needle 210 and the guide needle 230, and after the fire needle 210 is heated, it extends out of the extension hole, and the thermal insulation pad 500 is cushioned between the patient and the extension hole of the housing 100.
[0083] Preferably, the thermal insulation pad 500 is made of thermal insulation materials such as silica gel, polyurethane and aerogel.
[0084] It also includes a controller 600, which is electrically connected to the braking device and the heating structure 300. The controller 600 heats the fire needle 210 by controlling the heating structure 300, and controls the movement of the fire needle 210 and the guide needle 230 by controlling the braking device to treat the patient.
[0085] Preferably, the controller 600 may be a PLC controller or a single chip microcomputer.
[0086] A displacement sensor (not shown) is also included, which can sense the pushing distance of the fire needle 210 and the guide needle 230.
[0087] Specifically, the displacement sensor is arranged in the housing 100, and two displacement sensors are arranged, which are used to respectively sense the moving distance of the ignition needle 210 and the guide needle 230, and respectively sense the moving distance of the ignition needle 210 and the guide needle 230, and then feed back to the controller 600, and then the controller 600 controls the first driving device to control the moving distance of the ignition needle 210, so as to achieve the effect of device linkage. And the controller 600 can be responsible for automatically resetting the ignition needle 210 or the guide needle 230 within a preset time according to the sensing of the displacement sensor.
[0088] It is understandable that the displacement sensor can also sense the first slider 101 and the second slider 103, or the first base 102 and the second base 104 respectively, and feed back to the controller 600 as a basis for the displacement distance of the fire needle 210 and the guide needle 230.
[0089] A temperature sensor (not shown) is also included. The temperature sensor can be used to sense the temperature of the fire needle 210. By cooperating with the controller 600 and the heating structure 300, the heating temperature of the fire needle 210 can be accurately controlled.
[0090] Specifically, the temperature sensor is arranged in the shell 100. The temperature sensor can be attached to the fire needle 210 to measure the temperature of the fire needle 210, and it is electrically connected to the controller 600 to transmit the measured temperature of the fire needle 210 to the controller 600. The controller 600 can control the switch of the heating structure 300 according to the temperature of the fire needle 210, thereby controlling the temperature of the fire needle 210 and maintaining the fire needle 210 within the set temperature.
[0091] refer to Figure 1 , Figure 3 and Figure 4 The treatment process of the automatic fire needle 210 in the present invention is:
[0092] refer to Figure 3 The operator holds the color Doppler ultrasound probe in one hand to detect the abscess site of the patient, and holds the handle in the other hand to push the guide needle 230 out and insert it into the abscess site of the patient.
[0093] The displacement sensor connected to the controller 600 automatically senses the advancement depth of the guide needle 230 and feeds back to the controller 600. The operator operates the controller 600 to control the heating structure 300 to heat the fire needle 210 through the controller 600, and locks the second slider through the slide rail clamp of the second slider 103 to prevent the guide needle 230 from moving.
[0094] refer to Figure 4 When the fire needle 210 is heated to a predetermined temperature, the operator operates the controller 600 to control the first driving device to drive the fire needle 210 forward at a specific speed, and the advancement depth is the depth of the guide needle 230 pierced by the displacement sensor. Since the fire needle 210 is closely attached to the outer edge of the guide needle 230 for puncture, the full stroke of the fire needle 210 is completely consistent with the guide needle 230, and the abscess of the patient is accurately pierced.
[0095] The fire needle 210 is heated and inserted into the affected part, so as to achieve tissue denaturation and carbonization of the affected part, form a hardened drainage channel, and achieve the effect of continuous drainage. During operation, the liquid storage box 400 can catch the pus splashed into the housing 100 through the extension hole.
[0096] As the fire needle 210 begins to penetrate, the controller 600 calculates the time. After reaching the preset time, the controller 600 simultaneously controls the slide rail clamp of the second slider 103 to release, and controls the first drive device and the second drive device to respectively drive the fire needle 210 and the guide needle 230 to move and retract into the shell 100 to complete the treatment operation.
[0097] The present invention provides a guide needle 230 so that the operator can use color ultrasound to predict the position of the fire needle 210 inserted into the body through the guide needle 230 before the fire needle 210 is stimulated, thereby improving the predictability and safety of the puncture site of the fire needle 210; a controller 600, a braking device and a variety of sensors are provided, and the sensors sense the position and temperature. The controller 600 controls the braking device to control the stimulation time, recovery time and guide needle recovery time of the fire needle 210, thereby achieving precise adjustment of the treatment duration of the fire needle 210 and the puncture speed, and through the depth feedback of the guide needle 230, the puncture depth is controlled through feedback, thereby reducing human operating errors; a liquid storage box 400 is provided, and pus is collected through the liquid storage box 400, which can prevent pus splashing and contaminating the device.
[0098] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
