Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to an epidural puncture positioning and automatic emergency treatment device. Background Art

[0002] Nowadays, epidural anesthesia is a commonly used clinical anesthesia method. Anesthetic drugs are injected into the epidural space to block the spinal nerve roots, temporarily paralyzing the areas they innervate to block the pain sensation in body regions (such as the lower abdomen, buttocks, legs, pelvis, etc.) during surgery.

[0003] Since these medical procedures pose certain risks to patients, it is very important to pay attention to the main parts of the human body involved in these procedures, such as protecting the meninges and cerebrospinal fluid of the central nervous system. As is well known, the meninges include three layers: the dura mater, the arachnoid mater, and the pia mater. The dura mater is the outermost, strongest, and non-flexible layer of these three layers; the arachnoid mater is the intermediate septum and the pia mater is the innermost and fragile layer of the meninges. Also, cerebrospinal fluid is a clear body fluid that occupies the subarachnoid space, which is between the arachnoid mater and the pia mater of the meninges. In addition, the epidural venous plexus is widely distributed on the inner side of the spinal canal and is directly adjacent to the dura mater and nerve roots.

[0004] Epidural anesthesia uses a hollow spinal puncture needle to puncture the skin and subcutaneous tissue until the epidural space has been reached, which is spatially located below the dura mater. Initially, the area where the needle is inserted is blocked by local anesthesia. Subsequently, an epidural catheter is inserted through the inside of the needle into the epidural space, and is inserted cephalad or caudad according to the surgical site. Then the needle is removed, and the catheter is left in the epidural space. As needed, anesthetic drugs are injected into the patient's epidural space through the catheter to paralyze the body region in segments above and below the injection point.

[0005] Since the anatomical positions of the dura mater and the arachnoid mater are adjacent and closely attached, during epidural anesthesia puncture, sometimes the dura mater and the arachnoid mater may be accidentally punctured and entered the subarachnoid space, resulting in complications such as headache or total spinal anesthesia (more severe sensorimotor disorders and respiratory dysfunction than expected). If a vein is accidentally punctured during the puncture process, it may lead to an epidural hematoma compressing the spinal cord, causing potential destructive neurological consequences.

[0006] Therefore, during the puncture process, it is most important that the doctor must accurately insert the puncture needle into the designated position, quickly recognize, make a decisive decision, stop the puncture in a timely manner when an accidental puncture occurs, and complete remedial measures. This process places very high requirements on the doctor's operation.

[0007] The present invention aims at the above problems and provides an epidural puncture positioning and automatic emergency treatment device. Summary of the Invention

[0008] To overcome the problems presented in the background art, the present invention provides an epidural puncture positioning and automatic emergency treatment device.

[0009] An epidural puncture positioning and automatic emergency treatment device, comprising:

[0010] A puncture part, including a limit component, a puncture component, a pressing component and a control component. The pressing component includes a first presser, a second presser and a sliding tube. The first presser is fixedly connected to the sliding tube. The sliding tube slides inside the second presser. The second presser slides along the limit component. The control component is located on the side of the second presser away from the first presser. The puncture component is fixed inside the sliding tube.

[0011] The control component includes a control motor and a control ring. The outer wall of the control ring is provided with a control arm, and the inner wall is provided with a positioning block. The control arm is away from the limit component, the positioning block abuts against the sliding tube, and the control component is in the free mode. The control motor drives the control ring to rotate, so that the control arm abuts against the limit component and the positioning block disengages from the sliding tube, and the control component enters the limit mode.

[0012] Further, the puncture part further includes an adjustment component. One end of the adjustment component is inserted between the first presser and the second presser.

[0013] Further, a detection device is provided at the end of the drive rod away from the drive chamber. The detection device includes a calibration object and a sensor. The calibration object is fixedly connected to the drive rod.

[0014] Further, a sliding hole is provided inside the second presser. A limiting block is provided on the inner wall of the sliding hole. A sliding groove adapted to the limiting block is provided on the outer wall of the sliding tube.

[0015] Further, the control component further includes a control rod. One end of the control rod is rotatably connected to the control motor, and the other end is rotatably connected to the control ring.

[0016] Further, the puncture component includes a puncture needle, a convex block and a limiting structure. The convex block is fixedly connected to the outer side wall of the puncture needle. The limiting structure is detachably connected to the outer side wall of the puncture needle. The convex block and the limiting structure are respectively located on both sides of the pressing component.

[0017] Further, the limit component includes a guide rod and a connecting ring. The connecting ring is fixedly connected to the guide rod. The second presser slides along the guide rod.

[0018] Further, it further includes an induction part. The induction part includes a first detector, a vertical tube and a first connecting tube. One end of the first connecting tube is connected to the puncture component, and the other end is connected to the vertical tube. The first detector is located on the outer side wall of the vertical tube.

[0019] Further, it also includes an anesthesia unit. The anesthesia unit includes an anesthesia chamber, an anesthesia pump, and a second connecting tube. One end of the second connecting tube is detachably connected to the puncture assembly, and the other end is detachably connected to the anesthesia chamber. The anesthesia pump is located inside the second connecting tube.

[0020] Further, it also includes a detection unit. The detection unit includes a suction pump, a second detector, and a third connecting tube. One end of the third connecting tube is detachably connected to the puncture assembly, and the other end is connected to the suction pump. The second detector is located inside the third connecting tube.

[0021] Further, it also includes a patch unit; the patch unit includes a storage chamber, an injection pump, and a fourth connecting tube; one end of the fourth connecting tube is connected to the puncture assembly, and the other end is connected to the storage chamber; the injection pump is located inside the fourth connecting tube.

[0022] Advantages of the present invention: When in use, first connect the induction unit, the detection unit, the patch unit, and the puncture unit, and then insert the puncture assembly into the patient's body. When the liquid level in the induction unit drops, it indicates that the tip of the puncture assembly has reached the epidural space. At this time, the first detector emits an electrical signal to drive the control motor to work, causing the control arm to abut against the limit assembly, the positioning block to disengage from the sliding tube, and the control component to enter the limit mode; at this time, the second presser is limited on the limit assembly by the control component. Then, after the first presser drives the sliding tube to slide along the second presser to a suitable position, the driving motor locks to prevent the first presser from compressing the working hydraulic cylinder, thus restricting the relative positional relationship between the first presser and the second presser; then the suction pump is turned on to suck the body fluid at the front end of the puncture assembly into the third connecting tube, and the second detector analyzes whether there is blood or cerebrospinal fluid in the body fluid. If there is blood or cerebrospinal fluid in the body fluid, the driving motor is turned on, and the working hydraulic cylinder is driven to work through the driving hydraulic cylinder, causing the first presser to move away from the second presser, thus pulling the puncture assembly outward; after the puncture assembly reaches a suitable position, the injection pump is turned on to inject the liquid medicine in the storage chamber into the patient's body. If there is no blood and cerebrospinal fluid in the body fluid, the sealing cap is opened, the second connecting tube reaches through the epidural space through the puncture assembly, then the puncture assembly is removed, and then the second connecting tube is connected to the anesthesia chamber and the anesthesia pump, and the anesthesia pump is turned on to inject anesthetic into the patient's body.

[0039] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0040] AsFigure 1-13 An epidural puncture positioning and automatic emergency treatment device shown in the figure includes:

[0041] The puncture part 1 includes a limit component 11, a puncture component 12, a pressing component 13 and a control component 15. The pressing component 13 includes a first presser 131, a second presser 132 and a sliding tube 133. The first presser 131 is fixedly connected to the sliding tube 133. The sliding tube 133 slides inside the second presser 132. The second presser 132 slides along the limit component 11. The control component 15 is located on the side of the second presser 132 away from the first presser 131. The puncture component 12 is fixed inside the sliding tube 133.

[0042] The control component 15 includes a control motor 151 and a control ring 153. A control arm 1533 is provided on the outer wall of the control ring 153, and a positioning block 1534 is provided on the inner wall. The control arm 1533 is away from the limit component 11, and the positioning block 1534 abuts against the sliding tube 133, and the control component 15 is in the free mode. The control motor 151 drives the control ring 153 to rotate, so that the control arm 1533 abuts against the limit component 11, and the positioning block 1534 disengages from the sliding tube 133, and the control component 15 enters the limit mode. When the control component 15 is in the free mode, the second presser 132 can slide freely along the limit component 11, and the first presser 131 cannot drive the sliding tube 133 to pass through the second presser 132; when the control component 15 is in the limit mode, the second presser 132 is fixed on the limit component 11, and the first presser 131 can drive the sliding tube 133 to pass through the second presser 132.

[0043] Furthermore, the control component 15 further includes a control rod 152. One end of the control rod 152 is rotatably connected to the control motor 151, and the other end is rotatably connected to the control ring 153. The control motor 151 is a linear telescopic motor. When the linear telescopic motor extends, the control ring 153 is driven to rotate through the control rod 152, so that the control arm 1533 abuts against the limit component 11, and the positioning block 1534 disengages from the sliding tube 133, and the control component 15 enters the limit mode. When the linear telescopic motor contracts, the control ring 153 is driven to rotate in the reverse direction through the control rod 152, the control arm 1533 is away from the limit component 11, and the positioning block 1534 abuts against the sliding tube 133, and the control component 15 is in the free mode.

[0044] Furthermore, the puncture part 1 further includes an adjustment component 14. One end of the adjustment component 14 is inserted between the first presser 131 and the second presser 132. The purpose of the adjustment component 14 is:

[0045] When the control component 15 is in the limit mode, the adjusting component 14 can adjust the distance between the first presser 131 and the second presser 132. Since the puncture component 12 is fixed inside the sliding tube 133 and the first presser 131 is fixedly connected to the sliding tube 133, when the adjusting component 14 drives the first presser 131 away from the second presser 132, the puncture component 12 is pulled out of the patient's body, causing the puncture component 12 to gradually separate from the patient.

[0046] In some embodiments of the present application, as Figure 1-13 shown, the adjusting component 14 includes a working hydraulic cylinder, a driving tube 144, a driving hydraulic cylinder, and a driving motor 148. One end of the driving tube 144 is communicated with the working hydraulic cylinder, and the other end is communicated with the driving hydraulic cylinder. The driving motor 148 is connected to the driving hydraulic cylinder. When the driving motor 148 presses the driving hydraulic cylinder, the liquid inside the driving hydraulic cylinder can be injected into the working hydraulic cylinder through the driving tube 144, causing the working hydraulic cylinder to elongate and the first presser 131 to move away from the second presser 132. Similarly, when the first presser 131 approaches the second presser 132, the first presser 131 presses the working hydraulic cylinder, and the liquid inside the working hydraulic cylinder is injected into the driving hydraulic cylinder through the driving tube 144.

[0047] Specifically, the working hydraulic cylinder includes a working chamber 141, a push rod 142, and a working slider 143. One end of the push rod 142 is connected to the first presser 131, and the other end is inserted into the working chamber 141 and then connected to the working slider 143. The end of the working chamber 141 away from the push rod 142 is connected to the second presser 132.

[0048] Preferably, the adjusting component 14 includes two sets of working hydraulic cylinders. The two sets of working hydraulic cylinders are respectively located at both ends of the first presser 131, enabling the first presser 131 to move smoothly and preventing the first presser 131 from being displaced.

[0049] Specifically, the driving hydraulic cylinder includes a driving chamber 145, a driving piston 146, and a driving rod 147. One end of the driving rod 147 is connected to the driving motor 148, and the other end is inserted into the driving chamber 145 and then connected to the driving rod 147.

[0050] In the illustrative embodiments of the present application, as Figure 1-13 shown, a detection device 149 is provided at the end of the driving rod 147 away from the driving chamber 145. The detection device 149 includes a calibration object and a sensor. The calibration object is fixedly connected to the driving rod 147. The purpose of the detection device 149 is:

[0051] When the control component 15 is in the limit mode, check the moving distance of the driving rod 147 to determine the compressed length of the working hydraulic cylinder. After the first presser 131 drives the sliding tube 133 to slide along the second presser 132 to a suitable position, the driving motor 148 is locked to prevent the first presser 131 from compressing the working hydraulic cylinder, thus restricting the relative positional relationship between the first presser 131 and the second presser 132.

[0052] As Figure 1-13 shown, a sliding hole 1321 is provided inside the second presser 132. A limiting block 1324 is provided on the inner wall of the sliding hole 1321. A sliding groove 1331 adapted to the limiting block 1324 is provided on the outer wall of the sliding tube 133. The purpose of this design is to prevent the sliding tube 133 from rotating during the movement along the second presser 132, thereby driving the puncture assembly 12 to rotate and causing unnecessary damage to the patient.

[0053] As Figure 1-13 shown, a sliding arm 1322 is provided on the outer wall of the second presser 132. The sliding arm 1322 is slidably connected to the limiting assembly 11. A rotating groove 1325 is provided on the side of the second presser 132 away from the first presser 131. The control ring 153 rotates along the rotating groove 1325.

[0054] A through hole 1311 is provided inside the first presser 131. The through hole 1311 penetrates the sliding tube 133. The puncture assembly 12 passes through the pressing assembly 13 through the through hole 1311.

[0055] In some examples of the present application, as Figure 1-13 shown, the puncture assembly 12 includes a puncture needle 121, a convex block 123 and a limiting structure 124. The convex block 123 is fixedly connected to the outer side wall of the puncture needle 121. The limiting structure 124 is detachably connected to the outer side wall of the puncture needle 121. The convex block 123 and the limiting structure 124 are respectively located on both sides of the pressing assembly 13.

[0056] After passing the puncture needle 121 through the first presser 131 and the sliding tube 133, the limiting structure 124 is fixed on the outer wall of the puncture needle 121. Specifically, the limiting structure 124 is threadedly connected to the puncture needle 121.

[0057] Furthermore, the puncture assembly 12 further includes a mounting tube 122. The mounting tube 122 is located on the outer side wall of the puncture needle 121. One end of the mounting tube 122 is fixedly connected to the convex block 123, and the other end is detachably connected to the limiting structure 124. The limiting structure 124 is threadedly connected to the mounting tube 122. The function of the mounting tube 122 is to locally increase the strength of the puncture needle 121 and increase the stability of the connection between the puncture needle 121 and the pressing assembly 13.

[0058] In a specific example of the present application, asFigure 1-13 As shown, the limiting component 11 includes a guide rod 111 and a connecting ring 112. The connecting ring 112 is fixedly connected to the guide rod 111. The second presser 132 slides along the guide rod 111.

[0059] Furthermore, the connecting rings 112 are respectively located at both ends of the guide rod 111.

[0060] Specifically, the connecting ring 112 is a circular ring structure to prevent damage to the patient's skin.

[0061] Preferably, the limiting component 11 includes at least two guide rods 111 to prevent the pressing component 13 from rotating on the limiting component 11.

[0062] In some embodiments of the present application, as Figure 1-13 shown, it further includes a sensing part 2. The sensing part 2 includes a first detector 21, a vertical tube 22 and a first connecting tube 23. One end of the first connecting tube 23 is connected to the puncture assembly 12, and the other end is connected to the vertical tube 22. The first detector 21 is located on the outer side wall of the vertical tube 22. The purpose of the sensing part 2 is to detect whether there is negative pressure at the front end of the puncture needle 121. When there is negative pressure at the front end of the puncture needle 121, it means that the puncture needle 121 has passed through the dura mater. At this time, the liquid inside the vertical tube 22 will be inhaled into the patient's body through the puncture needle 121, causing the liquid level inside the vertical tube 22 to drop and triggering the alarm of the first detector 21.

[0063] Preferably, the first detector 21 is a photoelectric sensor to detect the change of the liquid level inside the vertical tube 22 at all times.

[0064] Preferably, a first one-way valve is provided inside the first connecting tube 23, so that the liquid inside the first connecting tube 23 can only flow unidirectionally. During the puncture process, the liquid inside the puncture needle 121 cannot flow out reversely through the first connecting tube 23, making the inside of the puncture needle 121 in a sealed state, preventing the patient's internal tissues from entering the inside of the puncture needle 121 to prevent the puncture needle 121 from being blocked.

[0065] When the patch part is working, the first one-way valve can also prevent the liquid inside the storage bin 51 from entering the vertical tube 22 through the first connecting tube 23, thus affecting the repair effect on the dural trauma.

[0066] In some embodiments of the present application, as Figure 1-13 shown, it further includes a detection part 4. The detection part 4 includes a suction pump 42, a second detector 43 and a third connecting tube 44. One end of the third connecting tube 44 is detachably connected to the puncture assembly 12, and the other end is communicated with the suction pump 42. The second detector 43 is located inside the third connecting tube 44.

[0067] Specifically, the second detector 43 is a spectrometer, which adopts Fourier transform infrared spectroscopy technology. This technology obtains corresponding spectra based on information such as the relative vibration between atoms inside molecules and molecular rotation. By analyzing the intensity, position, and shape of absorption peaks, the molecular structure of substances can be determined. In the wavelength range > 10 μm, by identifying individual or combined molecular vibration and rotation modes, the components of unknown compounds can be identified and qualitative and quantitative analyses can be carried out. FTIR (Fourier transform infrared absorption spectrometer) technology is widely used in the research of the structure and conformation of biological molecules such as proteins, lipids, carbohydrates, and nucleic acids. It not only has a series of advantages such as high light flux, low noise, and fast measurement speed, but also has a long infrared wavelength and small energy, and will not damage the living tissue structure during detection. FTIR technology has high sensitivity, accurate wave numbers, and good repeatability. It can analyze samples at the microgram or even nanogram level. It can not only be used for qualitative analysis, but also for quantitative determination, and can also analyze the components of unknown substances. Therefore, it can assist in judging whether cerebrospinal fluid or blood exists in the patient's body fluid. Cerebrospinal fluid or blood contains various electrolytes, proteins, a small amount of cells, etc., which are different from physiological saline or local anesthetic drugs, both of which are inorganic compounds. Therefore, there are significant differences in their spectroscopy. Through infrared spectroscopy technology, it is possible to distinguish the components in the body fluid sample and whether it is mixed with cerebrospinal fluid or blood.

[0068] The detection unit 4 further includes a buffer bin 41. One end of the suction pump 42 away from the third connecting pipe 44 is provided with a catheter. The catheter is communicated with the buffer bin 41. The function of the buffer bin 41 is to store the body fluid sucked out by the suction pump 42.

[0069] In some embodiments of the present application, as Figure 1-13 shown, it further includes a patch unit; the patch unit includes a storage bin 51, an injection pump 52, and a fourth connecting pipe 53; one end of the fourth connecting pipe 53 is connected to the puncture assembly 12, and the other end is communicated with the storage bin 51; the injection pump 52 is located inside the fourth connecting pipe 53. The storage bin 51 stores physiological saline or blood. When the second detector 43 detects that the body fluid contains blood or cerebrospinal fluid, the injection pump 52 is turned on to make the liquid inside the storage bin 51 enter the patient's body to block the needle track and repair the dura mater trauma.

[0070] In some embodiments of the present application, as Figure 1-13 shown, it further includes an anesthesia unit 3. The anesthesia unit 3 includes an anesthesia bin 31, an anesthesia pump 32, and a second connecting pipe 33. One end of the second connecting pipe 33 is detachably connected to the puncture assembly 12, and the other end is detachably connected to the anesthesia bin 31. The anesthesia pump 32 is located inside the second connecting pipe 33.

[0071] Preferably, a connection port is provided on the puncture assembly 12. A sealing cap is detachably connected to the connection port. The connection port is located at the end of the puncture needle 121 away from the patient. By opening the sealing cap, the second connecting tube 33 can reach through the epidural space via the puncture needle 121.

[0072] Preferably, the second connecting tube 33 is inserted into the interior of the puncture assembly 12 through the connection port.

[0073] The usage method of the present invention:

[0074] 1. The sensing part 2, the detection part 4, the patch part are connected to the puncture part 1;

[0075] 2. Push the pressing assembly 13 to insert the puncture assembly 12 into the patient's body;

[0076] 3. Continue to push the pressing assembly 13 until the control motor 151 is locked;

[0077] 4. If the cerebrospinal fluid is detected in the body fluid by the second detector 43, the puncture assembly 12 is automatically withdrawn until the inductor 2 indicates reaching the epidural space. After the injection pump 52 injects the liquid medicine in the storage bin 51 into the patient's body, the puncture assembly 12 is withdrawn from the patient's body; if blood is detected in the body fluid by the second detector 43, the puncture assembly 12 is withdrawn from the patient's body;; if neither blood nor cerebrospinal fluid is detected in the body fluid by the second detector 43, the sealing cap is opened, the second connecting tube 33 reaches through the epidural space via the puncture assembly 12, then the puncture assembly 12 is removed, and then the second connecting tube 33 is connected to the anesthesia chamber 31 and the anesthesia pump 32, and the anesthesia pump 32 is turned on to inject anesthetic into the patient's body.

[0078] The operating principle of the present invention:

[0079] When in use, first connect the induction part 2, the detection part 4, the patch part and the puncture part 1, and then insert the puncture assembly 12 into the patient's body. When the liquid level in the induction part 2 drops, it indicates that the tip of the puncture assembly 12 has reached the epidural cavity. At this time, the first detector 21 emits an electrical signal to drive the control motor 151 to work, so that the control arm 1533 abuts against the limit assembly 11, and the positioning block 1534 disengages from the sliding tube 133, and the control assembly 15 enters the limit mode; at this time, the second presser 132 is limited on the limit assembly 11 by the control assembly 15. Then, after the first presser 131 drives the sliding tube 133 to slide along the second presser 132 to a suitable position, the driving motor 148 is locked to prevent the first presser 131 from compressing the working hydraulic cylinder, thus restricting the relative positional relationship between the first presser 131 and the second presser 132; then the suction pump 42 is turned on to suck the body fluid at the front end of the puncture assembly 12 into the third connecting tube 44, and the second detector 43 analyzes whether there is blood or cerebrospinal fluid in the body fluid. If there is blood or cerebrospinal fluid in the body fluid, the driving motor 148 is turned on, and the working hydraulic cylinder is driven to work through the driving hydraulic cylinder, so that the first presser 131 moves away from the second presser 132, thus pulling the puncture assembly 12 outward; after the puncture assembly 12 reaches a suitable position, the injection pump 52 is turned on to inject the medicine in the storage bin 51 into the patient's body. If there is no blood and cerebrospinal fluid in the body fluid, the sealing cap is opened, so that the second connecting tube 33 passes through the puncture assembly 12 to reach and pass through the epidural cavity, then the puncture assembly 12 is taken out, and then the second connecting tube 33 is connected to the anesthesia bin 31 and the anesthesia pump 32, and the anesthesia pump 32 is turned on to inject anesthetic into the patient's body.
