Abstract
Description
Technical Field
[0001] This utility model relates to the field of minimally invasive anesthesia puncture auxiliary needle technology, and in particular to a novel minimally invasive anesthesia puncture auxiliary needle. Background Technology
[0002] A spinal anesthetic needle (also known as a lumbar anesthetic needle or epidural needle) is a medical device used to administer spinal anesthesia. It involves puncturing the patient's lumbar region to inject anesthetic drugs into the epidural space or subarachnoid space, thereby blocking nerve signals and achieving an anesthetic effect. The main components of a spinal anesthetic needle include the needle body, needle tip, handle, and sometimes a guiding system. This type of anesthesia is commonly used for lower abdominal, pelvic, or lower limb surgeries. When performing spinal anesthesia, an auxiliary puncture needle is needed. Using an auxiliary puncture needle allows for precise positioning of the lumbar region, ensuring the puncture needle enters the correct epidural or subarachnoid space, and reducing potential errors during the puncture process, thus improving the accuracy of the anesthetic injection. However, during use, due to the small size of the auxiliary needle, improper grip by medical personnel may lead to unstable operation, causing unexpected movement during the puncture process, thus affecting the accurate injection site of the anesthetic drug.
[0003] Existing minimally invasive anesthesia puncture auxiliary needles lack protective devices. When disposable anesthesia puncture auxiliary needles are retrieved, the unprotected needles may prick medical personnel or cleaning personnel during handling, increasing the risk of occupational injury. In addition, the needles may carry bodily fluids or blood, and the lack of protective devices increases the risk of infection, especially during handling. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel minimally invasive anesthesia puncture auxiliary needle.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel minimally invasive anesthesia puncture auxiliary needle, comprising a needle tube, a needle tip at the top of the needle tube, a fixing sleeve fixedly connected to the bottom of the needle tube, a baffle fixedly connected to the bottom of the fixing sleeve, a handle fixedly connected to the bottom of the baffle, a limiting ring fixedly connected to the top of the handle, a connecting block fixedly connected to the right side of the limiting ring, and a finger fixing ring fixedly connected to the end of the connecting block away from the limiting ring.
[0006] As a further description of the above technical solution:
[0007] The needle tube is provided with a protective shell on the outside, a rubber protective groove is fixedly connected to the top of the inner side of the protective shell, and a threaded sleeve is fixedly connected to the bottom of the inner side of the protective shell.
[0008] As a further description of the above technical solution:
[0009] The outer side of the fixing sleeve is provided with a threaded groove.
[0010] As a further description of the above technical solution:
[0011] Limiting rings are fixedly connected to the top, middle and bottom of the handle, and the number of limiting rings is set to three sets.
[0012] As a further description of the above technical solution:
[0013] The surface of the syringe is provided with multiple sets of scale lines, and the number of scale lines is several.
[0014] As a further description of the above technical solution:
[0015] The bottom of the protective shell is threadedly connected to the fixing sleeve.
[0016] This utility model has the following beneficial effects:
[0017] 1. In this utility model, by setting a limiting ring on the handle and a finger fixing ring on one side of the limiting ring, the improved grip can provide better stability, improve the accuracy of puncture, reduce hand tremors or accidental movement during operation, and make the puncture process smoother, thereby reducing the pain and discomfort felt by the patient during the puncture. The improved grip can reduce the doctor's hand fatigue and provide a more comfortable operating experience. The improved grip can improve the efficiency of operation, enabling the doctor to complete the puncture faster and shorten the patient's waiting time.
[0018] 2. In this utility model, by providing a protective shell on the outside of the needle tube and a rubber protective groove on the top of the inner side of the protective shell, the needle tip can be effectively covered, reducing the risk of needle stick injuries to medical staff and waste disposal personnel, preventing the needle tip from being exposed during the processing, reducing the possibility of infection and cross-contamination, and the bottom of the shell is provided with a threaded sleeve for easier installation. By setting up a protective device, the collection and processing of needle tips can be made more convenient and efficient, reducing the need for manual operation. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figure 1-3 The present invention provides an embodiment of a novel minimally invasive anesthesia puncture auxiliary needle, comprising a needle tube 1, a needle tip 2 at the top of the needle tube 1, a fixing sleeve 5 fixedly connected to the bottom of the needle tube 1, the bottom of the needle tube 1 being fixedly connected to the top of the fixing sleeve 5, a baffle 7 fixedly connected to the bottom of the fixing sleeve 5, the bottom of the fixing sleeve 5 being fixedly connected to the top of the baffle 7, a handle 13 fixedly connected to the bottom of the baffle 7, the bottom of the baffle 7 being fixedly connected to the top of the handle 13, a limiting ring 10 fixedly connected to the top of the handle 13, a connecting block 8 fixedly connected to the right side of the limiting ring 10, and a finger fixing ring 9 fixedly connected to the end of the connecting block 8 away from the limiting ring 10.
[0026] The needle tube 1 is provided with a protective shell 4 on the outside. A rubber protective groove 11 is fixedly connected to the top of the inner side of the protective shell 4. A threaded sleeve 12 is fixedly connected to the bottom of the inner side of the protective shell 4. A threaded groove 6 is opened on the outside of the fixed sleeve 5. Limiting rings 10 are fixedly connected to the top, middle and bottom of the handle 13. The number of limiting rings 10 is set to three sets. Multiple sets of scale lines 3 are provided on the surface of the needle tube 1. The bottom of the protective shell 4 is threadedly connected to the fixed sleeve 5.
[0027] Working principle: A fixing sleeve 5 is set at the bottom of the needle tube 1, and a threaded groove 6 is set on the outside of the fixing sleeve 5. A threaded sleeve 12 is set on the bottom of the inner side of the protective shell 4. The needle tube 1 is protected by rotating the protective shell 4 to prevent the needle from being exposed during the treatment process, thereby reducing the possibility of infection and cross-contamination. Three sets of limiting rings 10 are set on the outside of the handle 13. A finger fixing ring 9 is set on one side of the top limiting ring 10. During use, medical staff insert their fingers into the finger fixing ring 9, and place other fingers in the grooves of the limiting ring 10 and the handle 13. This changes the original grip force, provides better stability, improves the accuracy of puncture, and reduces hand tremors or accidental movement during operation. It also makes the puncture process more stable, thereby reducing the pain and discomfort felt by the patient during the puncture.
