Description

Technical Field

[0001] The invention relates to the technical field of epidural anesthesia, and more specifically, to an epidural anesthesia auxiliary needle insertion device. Background Art

[0002] Epidural anesthesia refers to epidural space block anesthesia, which is to inject local anesthetics into the epidural space to block the spinal nerve roots and temporarily paralyze the area controlled by them. This is called epidural space block anesthesia, abbreviated as epidural block. During epidural anesthesia, an auxiliary needle inserter is used to guide the anesthetic needle. However, the existing epidural anesthesia auxiliary needle inserter has the following shortcomings: during epidural anesthesia, the patient adopts a lateral position, and the anesthetic needle is inserted at a horizontal angle when the patient adopts a lateral position. At this time, the auxiliary needle inserter has a poor clamping effect on the anesthetic needle, which can easily cause a certain positional deviation of the anesthetic needle during insertion. At the same time, the auxiliary needle inserter attached to the patient's skin is also prone to loosening, which makes it difficult to stabilize the anesthetic needle and accurately insert the patient for anesthesia. Summary of the invention

[0003] The technical solution adopted by the present invention to achieve the technical purpose is: an epidural anesthesia auxiliary needle insertion device, whose structure includes a clamp composed of an outer ring plate, a guide plate and an inclined support rod. The outer ring plate is supported directly above the guide plate by symmetrically installed inclined support rods on both sides of the guide plate. A spring is also provided inside the outer ring plate, and the spring applies a sliding elastic force to the sliding shaft inside the outer ring plate. The sliding shaft is connected to one end of a connecting rod provided on the inner side of the outer ring plate, and the connecting rod drives the clamping plate provided at the other end to move in conjunction. The silicone sheet provided on the inner side of the clamping plate buffers and clamps the anesthesia syringe. A magnetic sheet is provided at the end of the outer ring plate. The outer ring plate is a semi-annular structure and is provided with two magnetic sheets. Each end of the outer ring plate is provided with a magnetic sheet, and the magnetic sheets on the two outer ring plates have opposite magnetic properties. There are two springs, sliding shafts and connecting rods on the outer ring plate.

[0004] As a further improvement of the present invention, a top spring is further provided inside the guide plate, which provides elastic force for the extrusion rod arranged on the inner side of the guide plate, and a hinge plate and a ball are provided at the inner end of the extrusion rod, and the ball slides on the hinge plate to assist the sliding of the anesthesia syringe. The top spring, extrusion rod, hinge plate and ball are each provided with three, and are equidistantly distributed in a ring shape inside the guide plate. Through the cooperation of three groups of top springs, extrusion rods and hinged plates, the lateral positions of the three balls inside the guide plate are adjusted.

[0005] As a further improvement of the present invention, a bonding plate is provided at the lower end of the guide plate, and a binding mechanism is provided on the bonding plate. The binding mechanism consists of a mounting rod, a disassembly rod and a strap. The mounting rod is provided at the side end of the bonding plate, and the disassembly rod is clamped and installed inside the mounting rod. The strap is provided on the outer surface of the long connecting plate on the disassembly rod. Two mounting rods and two disassembly rods are provided, and the head and tail ends of the strap are connected to the outside of the two disassembly rods.

[0006] As a further improvement of the present invention, a positioning rod is fixed on the inner side of the end of the disassembly rod and is plugged into the mounting hole set at the end of the mounting rod. Two disassembly rods are provided and are arranged at the head and tail ends of the long connecting plate. The positioning rods on the two disassembly rods are plugged into the mounting holes at the head and tail ends of the mounting rod.

[0007] As a further improvement of the present invention, the bonding plate is also provided with an adsorption mechanism, which is composed of a pull ring, a telescopic hose and a suction cup. A spring rod is provided at the lower end of the pull ring, and a plug provided at the lower end of the spring rod abuts against the top opening of the telescopic hose to seal the upper end of the suction cup. The telescopic hose has a pleated structure and is made of rubber material and has good elasticity.

[0008] As a further improvement of the present invention, a limit block and a ventilation groove are further provided inside the bonding plate. The limit block is arranged at the upper end of the ventilation groove to limit the pull ring inside the bonding plate, and a limit plate is provided at the middle end of the ventilation groove. When the spring rod pulls the plug to move inside the ventilation groove, it is limited by the limit plate. The ventilation groove has a structure that is narrow at both ends and wide in the middle.

[0009] The beneficial effects of the present invention are: 1. The anesthesia syringe is inserted into the outer ring plate and contacts the clamping plate. Under the linkage of the linkage rod and the spring applying sliding elastic force to the sliding shaft, the clamping plates on both sides elastically clamp the anesthesia syringe, thereby improving the stability of the anesthesia syringe. The lower end of the anesthesia syringe is elastically adjusted in the lateral position inside the guide plate by the cooperation of the top spring, the extrusion rod and the hinged plate. The balls play an auxiliary sliding effect, so that the anesthesia needle connected to the bottom of the anesthesia syringe is stably inserted into the position where the patient is anesthetized; 2. When the patient is in the side-lying position for anesthesia, the guide plate is attached to the skin of the patient's anesthesia position. At this time, the patient's limbs are wrapped around with a strap, and the positioning rod on the disassembly rod is inserted into the mounting hole of the mounting rod for fixation. At the same time, the suction cup is vacuum-adsorbed on the skin of the patient's anesthesia position through the elastic squeezing of the telescopic hose, thereby improving the firmness of the guide plate attached to the skin of the patient's anesthesia position, ensuring that the clamp stably clamps the anesthesia syringe, thereby improving the stability of the anesthesia needle when it is inserted horizontally.

The outer ring plate 11 is supported by the inclined support rods 13 on both sides, and the magnetic sheet 115 between the outer ring plates 11 on both sides is magnetically connected to form a ring-shaped structure. At this time, the anesthesia syringe is inserted into the outer ring The inside of the plate 11 is in contact with the clamping plate 114, and under the linkage of the connecting rod 113 and the spring 111 applying sliding elastic force to the sliding shaft 112, the clamping plates 114 on both sides elastically clamp the anesthetic syringe to improve the stability of the anesthetic syringe, and the lower end of the anesthetic syringe is elastically adjusted in the lateral position inside the guide plate 12 by the cooperation of the top spring 121, the extrusion rod 122 and the hinged plate 123 for three balls 124 inside the guide plate 12, and the ball 124 plays an auxiliary sliding effect, so that the anesthetic needle connected to the bottom of the anesthetic syringe can be stably inserted into the position for anesthesia of the patient.

[0020] A preferred technical solution, the outer ring plate 11 is a semi-annular structure, and is provided with two, each end of the outer ring plate 11 is provided with a magnetic sheet 115, and the magnetic sheets 115 on the two outer ring plates 11 have opposite magnetic properties, which can provide magnetic attraction between the two outer ring plates 11, so that the two outer ring plates 11 are firmly connected to form a ring structure; A preferred technical solution is that the outer ring plate 11 is provided with two springs 111, two sliding shafts 112 and two linkage rods 113. When the two springs 111 apply sliding elastic force to the sliding shaft 112, the two linkage rods 113 are linked to support the clamping plate 114 to provide a linkage support elastic force, so that the clamping plate 114 can clamp and support anesthesia syringes of different diameters, thereby improving the stability of the anesthesia syringes. A preferred technical solution, the top spring 121, the extrusion rod 122, the hinge plate 123 and the ball 124 are each provided with three, and are equidistantly distributed in a ring shape inside the guide plate 12. Through the cooperation of the three groups of top springs 121, the extrusion rod 122 and the hinge plate 123, the lateral positions of the three balls 124 inside the guide plate 12 are adjusted, and it is ensured that the balls 124 can assist in sliding, so that the anesthesia syringe stably penetrates into the guide plate 12 and remains on the same axis, so that the anesthesia needle connected to the bottom of the anesthesia syringe stably pierces the patient's anesthesia position; A preferred technical solution is that two mounting rods 211 and two disassembly rods 212 are provided, and the ends of the strap 213 are connected to the outside of the two disassembly rods 212, so that a closed loop structure is formed between the strap 213 and the laminating plate 2, so that the laminating plate 2 can be firmly attached to the skin position of the patient for anesthesia; A preferred technical solution is that there are two disassembly rods 212, and they are arranged at the head and tail ends of the long connecting plate 2122. The positioning rods 2121 on the two disassembly rods 212 are inserted into the mounting holes 2111 at the head and tail ends of the mounting rod 211, so that the long connecting plate 2122 is installed on the end of the bonding plate 2, so that the strap 213 can be quickly disassembled and assembled on the bonding plate 2. Embodiment 2: Based on embodiment 1, as shown in the attached Figure 5 To Attachment Figure 7 As shown: The laminating plate 2 is also provided with an adsorption mechanism 22, which is composed of a pull ring 221, a telescopic hose 222 and a suction cup 223. A spring rod 2211 is provided at the lower end of the pull ring 221, and a plug 2212 provided at the lower end of the spring rod 2211 abuts against the top opening of the telescopic hose 222 to seal the upper end of the suction cup 223. A limit block 23 and a vent groove 24 are also provided inside the laminating plate 2. The limit block 23 is provided at the upper end inside the vent groove 24 to limit the pull ring 221 inside the laminating plate 2, and a limit plate 241 is provided at the middle end inside the vent groove 24. When the spring rod 2211 pulls the plug 2212 to move inside the vent groove 24, it is limited by the limit plate 241. In the present invention, when the patient is anesthetized in the side-lying position, the guide plate 12 is attached to the skin of the patient's anesthesia position. At this time, the patient's limbs are restrained by the strap 213 It is wrapped around once, and the positioning rod 2121 on the disassembly rod 212 is inserted into the mounting hole 2111 of the mounting rod 211 for fixation. At the same time, the suction cup 223 is vacuum-adsorbed on the skin of the patient's anesthesia position through the elastic squeezing of the telescopic hose 222, thereby improving the firmness of the guide plate 12 fitting on the skin of the patient's anesthesia position, ensuring that the clamp 1 can stably clamp the anesthesia syringe, thereby improving the stability of the anesthesia needle during transverse insertion. After anesthesia, the guide plate 12 needs to be removed from the patient's skin, and the pull ring 221 is pulled under the connection of the spring rod 2211, so that the plug 2212 is separated from the upper end of the telescopic hose 222 inside the ventilation groove 24, and the external air enters the suction cup 223 along the ventilation groove 24, causing the suction cup 223 to lose its vacuum adsorption ability, thereby facilitating the removal of the bonding plate 2 from the patient's skin.

[0021] A preferred technical solution, the telescopic hose 222 is of a pleated structure and is made of rubber material with good elasticity. Under the elastic extrusion of the telescopic hose 222, the suction cup 223 squeezes out the air inside, so that the suction cup 223 can vacuum the patient's skin, thereby improving the firmness of the laminating plate 2 laminating on the patient's skin. A preferred technical solution is that the ventilation groove 24 is narrow at both ends and wide in the middle. When the plug 2212 is pulled to the middle of the ventilation groove 24, external air can enter the suction cup 223 along the ventilation groove 24, causing the suction cup 223 to lose its vacuum adsorption ability, making it easier to remove the bonding plate 2 from the patient's skin. Utilizing the technical solution of the present invention, or those skilled in the art designing similar technical solutions inspired by the technical solution of the present invention to achieve the above-mentioned technical effects, all fall within the protection scope of the present invention.
