Description

Technical Field

[0001] This utility model relates to the field of head-mounted intraoperative neurophysiological monitoring elastic mesh cap, specifically a head-mounted intraoperative neurophysiological monitoring elastic mesh cap. Background Technology

[0002] Spinal surgery is highly complex and risky. Intraoperative neurophysiological techniques can reduce surgical risks and safeguard the operation by analyzing and assessing the functional integrity of various nerve conduction pathways under the influence of surgical procedures in real time. Currently, the commonly used method for fixing head electrodes is to install head stimulation electrodes and recording electrodes and then wrap them with tape from the top of the patient's head to the chin. This method cannot achieve effective fixation. Changes in body position during surgery, intraoperative medication adjustments by the anesthesiologist, or accidental touches by the circulating nurse can all cause the fixation to loosen and the electrodes to fall off.

[0003] Therefore, those skilled in the art have provided a head-mounted elastic mesh cap for intraoperative neurophysiological monitoring to address the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to provide a head-mounted elastic mesh cap for intraoperative neurophysiological monitoring to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A head-mounted elastic mesh cap for intraoperative neurophysiological monitoring includes an elastic mesh cap body; a plurality of slot bases are fixedly connected to the outer surface of the elastic mesh cap body, the slot bases have internal slots for electrode slots, and the inner surface of the electrode slots has a plurality of limiting grooves; a plurality of side slot bases are provided on the outer side of the slot bases, the side slot bases have internal slots for side electrode slots, and the side electrode slots have internal slots for a plurality of side limiting grooves.

[0007] As a further embodiment of this utility model, an elastic headband is fixedly connected to the lower outer side of the main body of the elastic headband, and a female buckle fixing strap is fixedly connected to the lower left side of the elastic headband.

[0008] As a further embodiment of this utility model, a plurality of snap fasteners are fixedly connected to one side of the female buckle fixing strap.

[0009] As a further embodiment of this utility model, a sub-buckle fixing strap is fixedly connected to the lower right end of the elastic forehead band, and a plurality of buckles are fixedly connected to one side of the sub-buckle fixing strap.

[0010] As a further embodiment of this utility model, an inner comfort layer is fixedly connected to the inner surface of the elastic mesh cap body, and a sweat-absorbing and antibacterial layer is fixedly connected to the outer surface of the inner comfort layer.

[0011] As a further embodiment of this utility model, an elastic support layer is fixedly connected to the outer surface of the sweat-absorbing and antibacterial layer, and an outer protective layer is fixedly connected to the outer surface of the elastic support layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The electrode slots and limiting slots provide stable physical restraint for the electrodes, preventing displacement or loosening during surgery, even with slight head movements or external forces such as surgical manipulation. For example, in delicate brain surgeries requiring prolonged neurophysiological monitoring, firmly fixed electrodes ensure continuous and accurate signal acquisition, guaranteeing smooth monitoring. The electrode position can be adjusted by inserting it into the lateral electrode slot on the other side. This allows for precise placement of the electrodes based on individual patient head characteristics, surgical site, and nerve distribution, ensuring accurate stimulation of the motor center and stable reception of electrical activity in specific brain regions. This reduces signal errors caused by electrode position deviations, improving the accuracy and efficiency of input signals. It also provides a reliable foundation for subsequent signal processing and analysis, better supporting research and applications in related fields. Furthermore, the elastic mesh cap body, which allows for electrode position adjustments, facilitates quick and easy changes during surgery, eliminating the need to reposition the entire monitoring system.

[0014] 2. The inner comfort layer is mainly made of cotton or soft medical-grade silicone, which comes into direct contact with the patient's scalp. Its main purpose is to improve the patient's comfort and reduce discomfort such as skin allergies, itching, and stuffiness that may be caused by wearing the cap for a long time. It can also further enhance the adhesion stability between the electrodes and the scalp and ensure the accuracy of signal acquisition. The sweat-absorbing and antibacterial layer is mainly made of bamboo fiber, which has a porous structure and strong moisture absorption capacity. It can quickly absorb sweat, and bamboo fiber naturally contains an antibacterial substance called "bamboo kun", which has a significant inhibitory effect on a variety of bacteria, thereby ensuring the patient's hygiene and safety.

Detailed Implementation

[0020] Please see Figures 1-4 In this embodiment of the present invention, a head-mounted intraoperative neurophysiological monitoring elastic mesh cap includes an elastic mesh cap body 1; a plurality of slot bases 2 are fixedly connected to the outer surface of the elastic mesh cap body 1, the slot bases 2 have internal slots for electrode slots 3, and the inner surface of the electrode slots 3 has a plurality of limiting grooves 4; a plurality of side slot bases 5 are provided on the outer side of the slot bases 2, the internal slots of the side slot bases 5 have side electrode slots 6, and the internal slots of the side electrode slots 6 have a plurality of side limiting grooves 7; an elastic forehead band 8 is fixedly connected to the lower outer side of the elastic mesh cap body 1. A female buckle fixing strap 9 is fixedly connected to the lower left end of the elastic headband 8; several female buckles 10 are fixedly connected to one side of the female buckle fixing strap 9; a male buckle fixing strap 11 is fixedly connected to the lower right end of the elastic headband 8, and several male buckles 12 are fixedly connected to one side of the male buckle fixing strap 11; an inner comfort layer 13 is fixedly connected to the inner surface of the elastic headband 1, and a sweat-absorbing and antibacterial layer 14 is fixedly connected to the outer surface of the inner comfort layer 13; an elastic support layer 15 is fixedly connected to the outer surface of the sweat-absorbing and antibacterial layer 14, and an outer protective layer 16 is fixedly connected to the outer surface of the elastic support layer 15.

[0021] The working principle of this utility model is as follows: When the elastic net cap body 1 needs to be worn on the patient's head, simply adjust the elastic net cap body 1 to the same size as the patient's head using the elastic headband 8, then put the elastic net cap body 1 on the patient's head, and then loosen the elastic headband 8. It will then return to its original position and fit snugly against the patient's head, thus securing the elastic net cap body 1 to the patient's head. Then, the female buckle 10 and the female buckle 12 are secured against both sides of the patient's face using the female buckle 9 and the female buckle 11, making the elastic net cap body 1 more stable during subsequent use and preventing accidental contact. In the event of electrode displacement due to the elastic mesh cap body 1, align the locking block at one end of the electrode with the limiting groove 4 in the electrode slot 3, and then insert the electrode into the limiting groove 4 through the locking block until one end of the electrode is in complete contact with the patient's head surface. Release the locking block, and the electrode will be fixed in the electrode slot 3, ready for normal use. To adjust the electrode position, simply remove the electrode and insert it into the side electrode slot 6 in the side slot base 5 on the other side in the same manner. This completes the electrode position adjustment. The adjustment of electrode position allows for precise placement based on individual patient head characteristics, surgical site, and nerve distribution, ensuring accurate stimulation of the motor center and stable reception of electrical activity in specific brain regions. This reduces signal errors caused by electrode position deviations, improving the accuracy and efficiency of input signals. Furthermore, it provides a reliable foundation for subsequent signal processing and analysis, offering better support for research and applications in related fields. During surgery, adjustments to monitoring focus or the addition of new monitoring points may be necessary; the adjustable electrode cap body 1 facilitates these changes quickly and easily without requiring the repositioning of the entire monitoring system. The inner comfort layer 13 is mainly made of cotton or soft medical-grade silicone, which comes into direct contact with the patient's scalp. Its main purpose is to improve the patient's comfort and reduce discomfort such as skin allergies, itching, and stuffiness that may be caused by wearing the mesh cap for a long time. At the same time, it can also further enhance the stability of the fit between the electrodes and the scalp and ensure the accuracy of signal acquisition. The sweat-absorbing and antibacterial layer 14 is mainly made of bamboo fiber, which has a porous structure and strong moisture absorption capacity. It can quickly absorb sweat, and bamboo fiber naturally contains an antibacterial substance called "bamboo kun", which has a significant inhibitory effect on a variety of bacteria, thereby ensuring the patient's hygiene and safety.
