Description

Technical Field

[0001] The utility model relates to human daily necessities, in particular to the technical field of medical devices, in particular to a near-infrared drainage device after neurosurgery surgery. Background Art

[0002] Near infrared (NIR) and infrared refer to visible and invisible light with wavelengths between 620-1150. Near infrared and infrared can regulate the state of cytochrome C oxidase and thus affect mitochondrial activity and cell metabolism, improve the metabolism of neurons in damaged brain tissue, and achieve therapeutic purposes. In the field of neurosurgery, clinical studies at home and abroad have shown that transcranial NIR therapy can effectively improve the prognosis of cortical brain tissue infarction, and this has been verified in animal experiments.

[0003] External ventricular drainage and hematoma drainage are the most common drainage methods in neurosurgery, and their application range covers almost all craniotomy surgeries. Based on traumatic brain injury, these two external drainage methods play two major roles: monitoring and drainage. In addition to draining cerebrospinal fluid or bleeding, the external drainage tube can also monitor the physical properties of cerebrospinal fluid such as pressure and temperature through the probe.

[0004] In the current field of craniocerebral trauma, near-infrared technology can be seen in the application of detection technologies such as non-invasive intracranial pressure detection and non-invasive intracranial hematoma detection. However, the weak penetration ability of near-infrared technology is its biggest limitation in application transformation. In terms of detection technology application, near-infrared technology is also limited to epidural hematomas and subdural hematomas under the skull, and cannot detect deep hematomas. Research on the therapeutic application of near-infrared technology has also found that there is no therapeutic effect on patients with deep lesions. Although increasing the power can improve the penetration of near-infrared, it also produces a lot of heat generation side effects. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model provides a neurosurgery postoperative near-infrared drainage device, which overcomes the shortcomings of the existing technology, has a reasonable design, and avoids the treatment efficiency reduced by traditional near-infrared treatment due to penetrating the skull. Only a low dose of light intensity is required to achieve the treatment purpose required by the patient, reducing heat generation and further reducing the side effects of near-infrared treatment.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] A near-infrared drainage device for postoperative neurosurgery, comprising a transparent tube body and a near-infrared controller, wherein the inner cavity of the transparent tube body is fixedly mounted with the drainage tube body along the axial direction, and a drainage hole is arranged on the front end side of the transparent tube body, and the drainage hole is connected with the inner cavity of the drainage tube body; a near-infrared lamp bead is fixedly mounted on the front end of the inner cavity of the transparent tube body, and the near-infrared lamp bead is connected with the control port of the near-infrared controller through a first conductive wire;

[0008] A plurality of near-infrared light probes are evenly and fixedly installed along the axial direction on the front half of the inner wall of the transparent tube body, and the signal output end of each near-infrared light probe is connected to the signal input port of the near-infrared controller through a second conductive wire; the near-infrared controller is connected to an external power supply through a plug, and the near-infrared light probes and the near-infrared lamp beads are both located on the same side of the inner wall of the transparent tube body.

[0009] Preferably, the first conductive thread and the second conductive thread are both arranged along the inner wall of the transparent tube and pass through the rear end of the transparent tube.

[0010] Preferably, the front end of the transparent tube body is configured as an arc surface or a spherical surface.

[0011] Preferably, the near-infrared lamp bead is arranged at the front end of the transparent tube body and emits near-infrared light outward at 240° on a two-dimensional plane.

[0012] Preferably, three groups of near-infrared light probes are provided, and the three groups of near-infrared light probes are embedded in the inner wall of the transparent tube body, and the sensing ends of the near-infrared light probes face the outside of the transparent tube body.

[0013] The utility model provides a near-infrared drainage device for postoperative neurosurgery. It has the following beneficial effects: by arranging near-infrared lamp beads at the front end of the drainage tube body, the near-infrared lamp beads can reach deep around the lesion, thereby effectively avoiding the treatment efficiency of traditional near-infrared treatment reduced by penetrating the skull.

[0019] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention.

[0020] Embodiment 1, as Figure 1-2 As shown, a postoperative near-infrared drainage device for neurosurgery comprises a transparent tube body 1 and a near-infrared controller 2. A drainage tube body 3 is fixedly installed in the inner cavity of the transparent tube body 1 along the axial direction. A drainage hole 8 is provided on the side of the front end of the transparent tube body 1. The drainage hole 8 is connected to the inner cavity of the drainage tube body 3. A near-infrared lamp bead 4 is fixedly installed at the front end of the inner cavity of the transparent tube body 1. The near-infrared lamp bead 4 is connected to the control port of the near-infrared controller 2 through a first conductive wire 5.

[0021] A plurality of near-infrared light probes 6 are evenly and fixedly installed along the axial direction on the front half of the inner wall of the transparent tube body 1, and the signal output end of each near-infrared light probe 6 is connected to the signal input port of the near-infrared controller 2 through a second conductive wire 7; the near-infrared controller 2 is connected to an external power supply through a plug 10; the near-infrared light probes 6 and the near-infrared lamp beads 4 are located on the same side of the inner wall of the transparent tube body 1 and are arranged in the same axial direction.

[0022] Working principle:

[0023] When in use, the doctor inserts the transparent tube body 1 into the patient as an extraventricular drainage tube and / or a hematoma cavity drainage tube during surgery; after the patient returns to the intensive care unit after surgery, the first conductive wire 5 and the second conductive wire 7 on the transparent tube body 1 are connected to the near-infrared controller 2, so that the entire transparent tube body 1 can exert a near-infrared therapeutic effect.

[0024] When performing near-infrared therapy, firstly, the near-infrared controller 2 is used to control various parameters of the near-infrared lamp beads 4 (such as wavelength (nm), voltage (mV), current (mA), working power (W), whether pulsed operation (CW or PW), working time (h), cumulative energy generated by the work (joules) and thermal effect caused by the energy (℃) etc.) to select the appropriate wavelength and voltage for operation. If the brain temperature is high or the thermal effect of light therapy is more obvious, the voltage and working power can be reduced. If the penetration effect decreases after reducing the working power of the near-infrared lamp beads and cannot meet the treatment needs, pulse operation can be selected while maintaining normal power to reduce the thermal effect by reducing the working time.

[0025] When the near-infrared lamp bead 4 is in use, the near-infrared light emitted by the near-infrared lamp bead 4 is refracted and reflected when passing through different media, so that the original light path is changed and then received by the near-infrared light probe 6. The near-infrared light probe 6 then converts the optical signal into an electrical signal and transmits it to the near-infrared controller 2 for analysis. After the patient's near-infrared treatment course and the hematoma cavity drainage and ventricular external drainage courses are completed, the entire transparent tube body 1 can be directly taken out, and the first conductive wire 5 and the second conductive wire 7 can be cut off and discarded.

[0026] In this embodiment, by arranging each near-infrared light probe 6 and near-infrared lamp bead 4 on the same side of the inner wall of the transparent tube 1 in the same axial direction, because different media have different refractive indices, the distance between the near-infrared light probe 6 that receives more light (considering that the light path is also affected by tissue scattering) and the near-infrared lamp bead 4 can reflect the different refractive indices of the tissues passed by the light path, and determine the type of tissue and its content of water, melanin particles and other substances. For example, the refractive index of pure water is small and the refraction angle is large, so the light path needs to travel a longer distance to be received by the near-infrared light probe 6; on the contrary, the melanin particles in the brain tissue and skin contain more, the refractive index is large, and the refraction angle is small, so the light path only needs a shorter distance to be received by the near-infrared light probe 6. At the same time, affected by scattering, near-infrared light of different intensities can also be received by the near-infrared light probe 6. The water content is high, the light scattering rate is small, and the intensity of the near-infrared light that can be received is also higher; in the case of high mitochondrial content, the light refractive index is high, and the intensity of the near-infrared light that can be received is low. After receiving the near-infrared light signal, each near-infrared light probe 6 will transmit the signal to the near-infrared controller 2, which will analyze the signal and further adjust and control various parameters of the near-infrared lamp beads 4.

[0027] The utility model sets near-infrared lamp beads 4 at the front end of the drainage tube body 3, so that the near-infrared lamp beads 4 can reach the periphery of the lesion, thereby effectively avoiding the treatment efficiency reduced by traditional near-infrared treatment due to penetration of the skull. And only a low dose of light intensity is needed to achieve the treatment purpose required by the patient, reducing heat generation, thereby effectively further reducing the side effects of near-infrared treatment. It can improve the metabolism of brain tissue in deep injury lesions, increase the survival rate and improve the prognosis of patients.

[0028] Embodiment 2, as a further preferred embodiment of embodiment 1, the first conductive wire 5 and the second conductive wire 7 are both fixed along the inner wall of the transparent tube body 1 and pass through the rear end of the transparent tube body 1. By fixing the first conductive wire 5 and the second conductive wire 7 along the inner wall of the transparent tube body 1, the near-infrared light probe 6 and the near-infrared lamp bead 4 can be separated from the drainage space of the drainage tube body 3 to avoid mutual influence.

[0029] Embodiment 3, as a further preferred embodiment of embodiment 1, the front end of the transparent tube 1 is provided with an arc surface 9. The arc surface 9 can play a separating role when the transparent tube 1 enters the brain tissue, so as to reduce the damage to the brain tissue.

[0030] Embodiment 4, as a further preferred solution of embodiment 1, the near-infrared lamp bead 4 is arranged at the front end of the transparent tube body 1 and emits near-infrared light outward at 240° in a two-dimensional plane. There are three groups of near-infrared light probes 6, and the three groups of near-infrared light probes 6 are embedded in the inner wall of the transparent tube body 1, and the sensing ends of the near-infrared light probes 6 face the outside of the transparent tube body 1. And the three groups of near-infrared light probes 6 and the near-infrared lamp bead 4 are used as follows Figure 2 The sequence shown enables the three groups of near-infrared light probes 6 to measure different refractive indices and light scattering rates of different tissues.

[0031] Specifically, the near infrared controller 2 in the present invention adopts a well-known technical solution in the prior art, which will not be described in detail here.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
