Description

Technical Field

[0001] The invention relates to the technical field of anesthesia puncture devices, in particular to an anesthesia puncture device for surgical patients. Background Art

[0002] Spinal anesthesia is one of the commonly used anesthesia methods. Spinal anesthesia is achieved by injecting anesthetic drugs into specific areas in the spinal canal, such as the subarachnoid space, to block the conduction of spinal nerves. When performing spinal anesthesia, such as lumbar puncture, the anesthesiologist will be exposed to cerebrospinal fluid during the anesthesia operation. If relevant cerebrospinal fluid examinations are required clinically, the anesthesiologist can sample the cerebrospinal fluid during the anesthesia process. When the current surgical patient anesthesia puncture device is used for anesthesia puncture, the doctor relies on feeling the breakthrough feeling when the arachnoid membrane is punctured. It is not convenient to remind the doctor to penetrate the subarachnoid space, which may easily cause excessive puncture. At the same time, it is not convenient to automatically remove the bubbles of cerebrospinal fluid. When the traditional puncture device is used to inject anesthetic after docking the syringe, bubbles are easily generated. If the number of bubbles entering is large or the volume is large, it may cause serious consequences such as air embolism. At the same time, the puncture needle is not accurately adjusted when the small fiber bundle on the front side is blocked. It is not convenient to move the puncture needle in a small range manually, and the use accuracy is poor.

[0003] To this end, we propose a surgical patient anesthesia puncture device. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention adopts an anesthetic drug delivery part that can cooperate with the puncture needle sheath, which can facilitate doctors to quickly perform puncture anesthesia work. The structure is simple to operate, and it is more convenient for doctors to locate the arachnoid membrane and ensure the accuracy of drug injection into the subarachnoid space. The operation is flexible, and the elastic squeezing force of the anesthesia drug delivery part can be used to directly control the anesthetic needle to be pushed out after the doctor punctures the arachnoid membrane. The doctor can observe and understand intuitively, and avoid relying on the judgment method of breakthrough feeling. The doctor needs to frequently adjust the needle insertion depth many times and perform negative pressure testing with the syringe to determine the accuracy of the needle insertion position. The needle insertion depth control accuracy is poor, and it is also easy to damage the cauda equina nerve.

[0017] By adopting the bubble removal guide, the cerebrospinal fluid that needs to be drained during the patient's lumbar puncture can be drained. At the same time, this structure can avoid the appearance of bubbles when the anesthetic mixed with the cerebrospinal fluid is injected, so as to avoid the bubbles affecting the safety of the patient's anesthetic injection and causing serious consequences such as air embolism. At the same time, this structure can retain samples of the cerebrospinal fluid at one time, without the need to use a needle sheath to drain the cerebrospinal fluid and drip it into a test tube. This structure is more convenient for retaining samples and at the same time ensures the bubble isolation effect.

[0018] The fine-tuning control part can be used to achieve fine-tuning control work, which can be used to fine-tune the insertion depth of the anesthetic needle. The fine-tuning accuracy is higher, which can prevent the doctor from sliding directly on the patient's puncture tissue. Because the skin is elastic, the precision control is poor. This structure can hold the puncture sheath to ensure that the puncture sheath remains stable, and adjust the anesthetic needle inside the puncture sheath. It can assist in cerebrospinal fluid drainage through negative pressure before anesthesia injection, without the need for cumbersome docking syringes.

[0019] The puncture disinfection device used can disinfect the front end of the anesthesia needle and the surface of the puncture sheath, making the disinfection and cleaning more comprehensive and avoiding the inconvenience of manual cleaning and disinfection wiping, as well as the problem of easy omissions.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figures 1 to 11 As shown:

[0034] The present invention provides a technical solution: a surgical patient anesthesia puncture device, comprising a puncture handpiece 1, on which a puncture needle sheath 2 is installed; an anesthesia administration part 3 is installed on the puncture handpiece 1; the anesthesia administration part 3 is used to slide on the puncture needle sheath 2; the puncture needle sheath 2 is used to guide the anesthesia administration part 3; a debubble guide 4 is installed on the puncture handpiece 1; the debubble guide 4 is used for exhaust; a sampling closure 5 is installed on the debubble guide 4; the sampling closure 5 is used to close the debubble guide 4; a fine-tuning control part 6 is installed on the puncture handpiece 1; the fine-tuning control part 6 is used to magnetically attract the anesthesia administration part 3; a puncture disinfection part 7 is installed on the puncture needle sheath 2; the puncture handpiece 1 comprises: a puncture connecting tube 101 and a handle 102, and the handle 102 is installed on the puncture connecting tube 101; the handle 102 is used for a doctor to hold.

[0035] Among them, the puncture handpiece 1 also includes: an exhaust guide tube 103, which is fixedly installed on the puncture connecting tube 101; the inner side of the exhaust guide tube 103 is provided with a thread; the puncture needle sheath 2 includes: a closing cover 201, a hand-held ear 2011 and a puncture sheath 202, the closing cover 201 is threadedly connected to the front end of the puncture connecting tube 101; the puncture sheath 202 is fixedly installed on the closing cover 201, and the front end of the puncture sheath 202 is a bevel structure; two hand-held ears 2011 are fixedly installed on the closing cover 201; the puncture sheath 202 is provided with segmented scale marks; the anesthesia administration part 3 includes: an anesthesia movable plug 301, a docking magnet 302, a tension spring 303, an anesthesia needle 304 and a needle tip bevel 3041, the anesthesia movable plug 301 is slidably sleeved on the puncture connecting tube 101; a rubber ring is provided on the outer side of the anesthesia movable plug 301; two docking magnets 302 are fixedly embedded at the tail of the anesthesia movable plug 301, and the two docking magnets The iron 302 protrudes from the anesthesia movable plug 301 respectively, and the two docking magnets 302 are used to limit the anesthesia movable plug 301. The two docking magnets 302 protrude from the anesthesia movable plug 301 respectively. Even if the docking magnets 302 are attached to the inner wall of the puncture connecting tube 101, a gap can be formed between the anesthesia movable plug 301 and the inner wall of the puncture connecting tube 101, ensuring that the air vent 4011 on the debubble guide tube 401 can smoothly relieve pressure and ventilate; a tension spring 303 is sleeved inside the puncture connecting tube 101; the end of the tension spring 303 is connected to the front side of the anesthesia movable plug 301; the other end of the tension spring 303 is connected to the inner side of the closing cover 201; an anesthesia needle 304 is fixedly installed on the anesthesia movable plug 301, and the anesthesia needle 304 is slidably inserted into the inside of the puncture sheath 202; the anesthesia needle 304 is used for lumbar anesthesia puncture; a needle tip bevel 3041 is provided at the front end of the anesthesia needle 304, and the needle tip bevel 3041 is used to prevent the front end of the anesthesia needle 304 from being blocked and affecting the injection;The anesthetic needle 304 penetrates the anesthetic mobile plug 301, and the anesthetic administration part 3 can cooperate with the puncture needle sheath 2, which can facilitate the doctor to quickly perform puncture anesthesia. The structure is simple to operate, which is more convenient for the doctor to locate the arachnoid membrane and ensure the accuracy of the drug injection in the subarachnoid space, and can improve the flexibility of structural operation. By using the elastic squeezing force of the anesthetic administration part 3, the anesthetic needle 304 can be directly controlled to be pushed out after the doctor punctures the arachnoid membrane. The doctor can observe and understand intuitively, avoiding the problem that the doctor needs to make frequent adjustments many times and the depth control accuracy of the needle insertion is not good. The muscle tissue between the lumbar vertebrae will produce resistance to the anesthetic needle 304, and the anesthetic needle 304 will push the anesthetic mobile under the action of the resistance. The plug 301 moves backward, stretching the tension spring 303. At this time, only the sharp part of the front end of the anesthesia needle 304 is exposed at the front end of the puncture sheath 202. However, as the depth of the needle increases, when the front end of the anesthesia needle 304 pierces the arachnoid membrane, the front end of the puncture sheath 202 has just passed through the arachnoid membrane. The subarachnoid space is mainly cerebrospinal fluid, small fiber bundles and cauda equina nerves, and its resistance is relatively small. Under the pull of the tension spring 303, the anesthesia mobile plug 301 will drive the anesthesia needle 304 to move forward and extend from the front end of the puncture sheath 202 to ensure that the anesthesia position is located inside the subarachnoid space. During this process, the doctor can observe that the anesthesia mobile plug 301 moves forward inside the puncture connecting tube 101. At this time, the staff immediately stops the needle insertion and can carry out subsequent cerebrospinal fluid drainage and anesthesia work. ;

[0036] The debubble guide 4 includes: a debubble guide cylinder 401, a lower limit ring 402 and an air leakage hole 4011. The bottom of the debubble guide cylinder 401 is provided with a thread; the bottom of the debubble guide cylinder 401 is threadedly connected to the exhaust guide pipe 103; the inner side of the debubble guide cylinder 401 is fixedly installed with a lower limit ring 402; a circle of air leakage holes 4011 is provided on the debubble guide cylinder 401; the air leakage hole 4011 is connected to the puncture connection cylinder 101; the top of the inner side of the debubble guide cylinder 401 is a slope structure; the sampling closure 5 includes: a sampling connection shaft 501, a lower baffle 502 and an upper baffle 503, and the sampling connection shaft 501 is slidably installed on the upper baffle 503. The sampling connection shaft 501 is fixedly provided with a lower baffle 502 at the bottom thereof; the lower baffle 502 is attached to the lower limit ring 402; the sampling connection shaft 501 is fixedly provided with an upper baffle 503; the top of the upper baffle 503 is attached to the inner inclined surface of the debubble guide cylinder 401; the outer surfaces of the lower baffle 502 and the upper baffle 503 are respectively provided with a rubber coating; the sampling sealing member 5 further comprises: a safety spring 504, the sampling connection shaft 501 is sleeved with the safety spring 504, and the end of the safety spring 504 is connected to the sampling connection shaft 501; the other end of the safety spring 504 is fixedly provided on the top of the debubble guide cylinder 401; The safety spring 504 is used to elastically push the sampling connection shaft 501 upward. The bubble removal guide 4 can be used to drain the cerebrospinal fluid that needs to be drained during the patient's lumbar puncture. At the same time, this structure can avoid the appearance of bubbles when the anesthetic mixed with the cerebrospinal fluid is injected, and play a role in discharging bubbles, which can prevent bubbles from affecting the safety of the patient's anesthetic injection. If the number of bubbles entering is large or the volume is large, it may cause serious consequences such as air embolism. At the same time, this structure can retain samples of cerebrospinal fluid at one time, without using a needle sheath to drain cerebrospinal fluid dripping into a test tube. This structure is more convenient for retaining samples, while ensuring the bubble isolation effect and operation. The method is simple and convenient. As the cerebrospinal fluid flows out normally, the puncture connecting tube 101 will gradually be filled, and the liquid level in the debubble guide tube 401 will rise to fill the debubble guide tube 401. When the liquid level is close to the top of the debubble guide tube 401, the downward pressure sampling connecting shaft 501 can be released. At this time, the lower baffle plate 502 is immersed in the cerebrospinal fluid. When the sampling connecting shaft 501 is released, under the pressure of the safety spring 504, the lower baffle plate 502 and the upper baffle plate 503 will be sealed and fit the lower limit ring 402 and the inner side of the debubble guide tube 401 to achieve sample retention and sealing. At this time, there are no more bubbles in the puncture connecting tube 101, and the bubbles can be discharged.

[0037] The fine-tuning control part 6 includes: a regulating shaft 601 and a needle plugging rubber block 602, wherein the regulating shaft 601 is slidably plugged into the handle 102; a through hole is provided on the regulating shaft 601; a needle plugging rubber block 602 is fixedly sleeved inside the regulating shaft 601; the needle plugging rubber block 602 is used to insert the syringe; groove structures are provided on both sides of the needle plugging rubber block 602; the fine-tuning control part 6 also includes: a regulating piston 603 and a moving magnet ring 604, wherein the regulating piston 603 is fixedly mounted at the end of the regulating shaft 601; The piston 603 is slidably sleeved inside the handle 102; a rubber ring is provided on the outer side of the regulating piston 603; a movable magnet ring 604 is fixedly installed on the regulating piston 603, and the movable magnet ring 604 is used to magnetically attract the two docking magnets 302. The fine-tuning control part 6 is adopted to realize fine-tuning control work, which can be used to fine-tune the insertion depth of the anesthesia needle 304. The method of sliding the regulating shaft 601 on the handle 102 is more accurate and has a higher fine-tuning accuracy, which avoids the doctor from sliding directly on the patient's punctured tissue because the skin The skin is elastic and the precision control is poor. The present structure can hold the puncture sheath 202 to ensure that the puncture sheath 202 remains stable, and the anesthetic needle 304 can be adjusted inside the puncture sheath 202. At the same time, the cerebrospinal fluid can be drained by negative pressure before the anesthesia injection. Sometimes, due to the patient's weak constitution or low intracranial pressure, the cerebrospinal fluid will flow out very slowly or not at all, which makes it impossible for the doctor to directly judge whether the puncture needle has accurately entered the subarachnoid space. At this time, it is particularly important to perform a negative pressure test. The drainage test currently requires the doctor to operate the syringe, which has poor flexibility; pull the regulating shaft 601 outward in a small range to accelerate the extraction of cerebrospinal fluid. The cerebrospinal fluid can be discharged faster under negative pressure suction, which is convenient for the doctor to know whether the cerebrospinal fluid can be discharged. Pushing the regulating shaft 601 can drive the regulating piston 603 to move close to and magnetically attract the docking magnet 302. At this time, sliding the regulating shaft 601 can drive the anesthesia moving plug 301 to fine-tune the position of the anesthetic needle 304, because the diameter of the anesthetic needle 304 is small, and small fiber bundles and other tissues are prevented from blocking the anesthetic needle 304.

[0038] Embodiment 2, on the basis of embodiment 1, the puncture disinfection piece 7 comprises: a cleaning ring 701 and a cleaning cotton ring 702, the cleaning ring 701 is a rubber elastic structure; the cleaning ring 701 is sleeved on the puncture sheath 202; the cleaning cotton ring 702 is fixedly installed on the inner side of the cleaning ring 701; disinfectant is adsorbed on the cleaning cotton ring 702, and the adopted puncture disinfection piece 7 can be used to disinfect the front end of the anesthesia needle 304 and the surface of the puncture sheath 202 before the preliminary injection work is carried out, which can ensure the safety of the use of this structure. At the same time, the disinfection and cleaning of this structure is more comprehensive, avoiding the inconvenience of manual cleaning and disinfection wiping, and can be disinfected simply and quickly.

[0039] The working principle of this embodiment is as follows: first, holding the handle 102, inserting the puncture sheath 202 and the anesthetic needle 304 between the patient's lumbar vertebrae, the needle tip bevel 3041 can be easily inserted between the lumbar vertebrae by virtue of its sharp structure, as the needle tip is inserted into the patient's lumbar vertebrae, the muscle tissue between the lumbar vertebrae will produce resistance to the anesthetic needle 304, at this time, the anesthetic needle 304 will push the anesthetic movable plug 301 backward under the action of the resistance, and stretch the tension spring 303, at this time, only the front end of the anesthetic needle 304 is exposed at the front end of the puncture sheath 202, but as the needle insertion depth increases, when the front end of the anesthetic needle 304 pierces the arachnoid membrane, the front end of the puncture sheath 202 has just passed through the arachnoid membrane, and the subarachnoid space is mainly cerebrospinal fluid, small fiber bundles and cauda equina, and the resistance is relatively small, and under the pulling of the tension spring 303 , the anesthesia moving plug 301 will drive the anesthesia needle 304 to move forward and extend from the front end of the puncture sheath 202 to ensure that the anesthesia position is located inside the subarachnoid space. During this process, the doctor can observe that the anesthesia moving plug 301 moves forward inside the puncture connecting tube 101. At this time, the doctor immediately stops inserting the needle and holds the handle 102 for puncture. When the anesthesia needle 304 pierces the subarachnoid space, the doctor presses down the sampling connecting shaft 501 with his fingers, driving the lower baffle plate 502 and the upper baffle plate 503 to move downward, and no longer fits the closed lower limit ring 402 and the inner inclined surface of the bubble removal guide tube 401. At this time, the cerebrospinal fluid led out by the anesthesia needle 304 will flow out, and the air vent 4011 plays a role in relieving pressure to ensure that the cerebrospinal fluid can be discharged. Cerebrospinal fluid is an important criterion for the success of puncture, and the anesthetic needs to be mixed. The cerebrospinal fluid is pushed into the subarachnoid space. As the cerebrospinal fluid flows out normally, it will gradually fill up the puncture connecting tube 101, and the liquid level in the debubble guide tube 401 will rise to fill up the debubble guide tube 401. When the liquid level is close to the top of the debubble guide tube 401, the downward pressure sampling connecting shaft 501 can be released. At this time, the lower baffle plate 502 is immersed in the cerebrospinal fluid. When the sampling connecting shaft 501 is released, under the pressure of the safety spring 504, the lower baffle plate 502 and the upper baffle plate 503 will be sealed and fit the lower limit ring 402 and the inner side of the debubble guide tube 401 to achieve sample retention and sealing work. After the subsequent anesthesia work is completed, the debubble guide tube 401 can be directly rotated and removed from the exhaust guide tube 103 for subsequent inspection work; when the sampling connecting shaft 501 is pressed to pass through the anesthesia needle 304, the debubble guide tube 401 can be removed. Before the cerebrospinal fluid flows out, the regulating shaft 601 can be pulled outward in a small range to accelerate the extraction of cerebrospinal fluid. The cerebrospinal fluid can be discharged faster under negative pressure suction. When the cerebrospinal fluid is discharged, after pressing down the sampling connection shaft 501, the regulating shaft 601 is pushed inward, which can drive the regulating piston 603 to move close to and magnetically attract the docking magnet 302. At this time, the sliding regulating shaft 601 can drive the anesthesia movable plug 301 to fine-tune the position of the anesthesia needle 304 to prevent small fiber bundles from blocking the anesthesia needle 304. During the process, the syringe is inserted into the needle plug-in rubber block 602 to inject the anesthetic. Before using this structure for puncture, disinfectant is dripped on the cleaning cotton ring 702. The doctor pulls the cleaning ring 701 outward to drive the cleaning cotton ring 702 to be sleeved on the surface of the puncture sheath 202 for disinfection.
