Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to an optic nerve sheath intra-pressure monitor. Background Art

[0002] Traumatic optic neuropathy, also known as TON, refers to the structural and pathological changes of the optic nerve caused by a sudden blunt external force on the head and face. Its incidence rate accounts for about 0.5% to 5% of craniocerebral trauma, and its consequences are serious. About 70% of patients suffer from severe visual impairment after injury and have difficulty recovering. It is the primary cause of permanent visual impairment in young and middle-aged people.

[0003] The current treatment for TON is generally ETOCD surgery. With the continuous development and progress of medical methods, the success rate and safety of ETOCD surgery itself have been greatly improved.

[0004] However, during ETOCD surgery, the patient's "individualized" clinical data still cannot be further used on the basis of routine clinical factors to accurately evaluate the nature of optic nerve damage using objective imaging examination methods to screen patients who will benefit from surgery and predict visual prognosis. At the same time, there is no reference basis for the extent of removal of the optic canal and its surrounding bone and whether the optic nerve sheath is incised during surgery, which depends solely on the surgeon's clinical experience.

[0005] Therefore, it is necessary to provide a new optic nerve sheath pressure monitor to solve the above technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides an optic nerve sheath intra-pressure monitor.

[0007] The utility model provides an optic nerve sheath pressure monitor comprising:

[0008] A measuring needle, one end of which is fixedly connected to a pressure-guiding pipe A, and the other end of which is fixedly connected to an electronic pressure sensor, the electronic pressure sensor is fixedly connected to a pressure-guiding pipe B, and the other end of which is fixedly connected to a sterile barrel, the electronic pressure sensor is fixedly connected to a display via a data cable, a mounting bracket is provided on the pressure-guiding pipe A, both ends of the mounting bracket are provided with bayonet holes, and the pressure-guiding pipe A is located in the two bayonet holes, a mounting seat is slidably connected in the mounting bracket, and the top and bottom of the mounting seat are rotatably connected to limit rods.

[0009] Preferably, a fixing frame is provided on one side of the measuring needle, a load-bearing seat is slidably connected to the fixing frame, a mounting rod is rotatably connected to the load-bearing seat, a fixing clamp is fixedly connected to the mounting rod, and the measuring needle is located between the fixing clamps.

[0010] Preferably, an anti-backflow solenoid valve A is fixedly connected between the measuring needle and the electronic pressure sensor via a pressure-guiding pipeline A, and the measuring needle and the pressure-guiding pipeline A are interconnected.

[0011] Preferably, a micro water pump and an anti-backflow solenoid valve B are respectively fixedly connected between the electronic pressure sensor and the sterile barrel through a pressure-conducting pipe B, and the anti-backflow solenoid valve B is located between the electronic pressure sensor and the micro water pump.

[0012] Preferably, a screw rod is threadedly connected to the mounting frame, and one end of the screw rod is rotatably connected to the mounting seat, and the other end of the screw rod is fixedly connected to a knob B.

[0013] Preferably, a roller is rotatably connected inside the bayonet, and a magnet is fixedly connected to the end of the limit rod.

[0014] Preferably, a screw rod is rotatably connected in the fixing frame, and a knob A fixedly docked with the top end of the screw rod is provided at the top of the fixing frame, and the screw rod is threadedly connected to the load-bearing seat.

[0015] Compared with the related art, the optic nerve sheath pressure monitor provided by the utility model has the following beneficial effects:

[0016] 1. The utility model inserts a measuring needle into the optic nerve at the corresponding position of the movement, converts the liquid pressure in the pressure-guiding pipe A and the pressure-guiding pipe B into a real-time electrical signal through a sensor, and finally converts the electrical signal into a real-time pressure signal, which is presented on a display in the form of a waveform curve and a blood pressure value, so that the specific value of the pressure inside the optic nerve sheath can be known. The obtained value can be used to accurately evaluate the nature of optic nerve damage to screen patients who will benefit from surgery and predict visual prognosis. At the same time, it can be used as a reference for the range of bone removal of the optic canal and its surroundings and whether the optic nerve sheath should be incised during surgery.

[0017] 2. During use of the utility model, the pressure-conducting pipeline A is stuck in the bayonet of the mounting frame, and then the screw rod is rotated to drive the mounting seat to move. At this time, the limit rod moves with the mounting seat, and the mounting seat can be used to pull the pressure-conducting pipeline A to bend the pressure-conducting pipeline A and retract it into the mounting frame, thereby changing the length of the pressure-conducting pipeline A to avoid the pressure-conducting pipeline A being too long, which may cause the pressure-conducting pipeline A to be easily obstructed and affected during the monitoring operation, resulting in inconvenient operation.

[0018] 3. The utility model can fix the measuring needle by using a fixing clamp, change the inclination of the measuring needle by rotating the mounting rod, and use a screw to drive the load-bearing seat to rise or fall along the fixing frame, thereby changing the height of the measuring needle, which effectively improves the auxiliary function of the device for medical personnel during operation.

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0026] See also Figures 1 to 4 The embodiment of the utility model provides an optic nerve sheath pressure monitor, which includes: a measuring needle 1, an electronic pressure sensor 2, a display 3, a sterile barrel 4 and a mounting frame 6.

[0027] In the embodiments of the present invention, please refer to Figure 1 and Figure 2One end of the measuring needle 1 is fixedly connected to a pressure-guiding pipe A11, and the other end of the pressure-guiding pipe A11 is fixedly connected to an electronic pressure sensor 2, a pressure-guiding pipe B21 is fixedly connected to the electronic pressure sensor 2, and the other end of the pressure-guiding pipe B21 is fixedly connected to a sterile barrel 4, a display 3 is fixedly connected to the electronic pressure sensor 2 via a data line, an anti-backflow solenoid valve A12 is fixedly connected between the measuring needle 1 and the electronic pressure sensor 2 via the pressure-guiding pipe A11, and the measuring needle 1 and the pressure-guiding pipe A11 are interconnected, a micro-water pump 22 and an anti-backflow solenoid valve B23 are respectively fixedly connected between the electronic pressure sensor 2 and the sterile barrel 4 via the pressure-guiding pipe B21, and the anti-backflow solenoid valve B23 is located between the electronic pressure sensor 2 and the micro-water pump 22.

[0028] It should be noted that: the sterile barrel 4 is filled with sterile liquid. When monitoring the pressure inside the optic nerve sheath, the measuring needle 1 is inserted into the optic nerve, and then the sterile liquid in the sterile barrel 4 is transported to the pressure-guiding pipe B21 and the pressure-guiding pipe A11 through the micro water pump 22. At this time, the anti-backflow solenoid valve B23 and the anti-backflow solenoid valve A12 can prevent the sterile liquid from flowing back. The optic nerve can block the sterile liquid due to the internal pressure. At this time, the electronic pressure sensor 2 can measure the pressure, and the measurement result is transmitted to the display 3 through the data line by converting the electrical signal into a real-time pressure signal. At this time, the display 3 presents the waveform curve and blood pressure value through the display 3, so that there is an objective basis for the intraoperative optic nerve wall bone removal range and whether the optic nerve sheath is cut, and the ETOCD operation process is improved and optimized. At the same time, the imaging group data of orbital HRCT, MRI and ultrasound, the optic nerve sheath pressure and the intraoperative condition, and the visual follow-up prognosis of TON patients are correlated and analyzed to clarify the value of imaging group data and optic nerve sheath pressure monitoring for disease diagnosis, treatment guidance and prognosis prediction, and establish a precise diagnosis and treatment system for TON, so as to standardize the diagnosis and treatment of TON and improve the visual prognosis of TON.

[0029] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 A fixing frame 5 is provided on one side of the measuring needle 1, a load-bearing seat 51 is slidably connected to the fixing frame 5, and a mounting rod 52 is rotatably connected to the load-bearing seat 51, a fixing clamp 53 is fixedly connected to the mounting rod 52, and the measuring needle 1 is located between the fixing clamps 53, a screw rod 54 is rotatably connected inside the fixing frame 5, and a knob A55 fixedly docked with the top of the screw rod 54 is provided on the top of the fixing frame 5, and the screw rod 54 is threadedly connected to the load-bearing seat 51.

[0030] It should be noted that the measuring needle 1 can be fixed by the fixing clamp 53, so that the measuring needle 1 can be more stably rotated during use. The deflection angle of the measuring needle 1 can be adjusted by rotating the mounting rod 52, and the screw 54 can be driven to rotate by turning the knob A55. At this time, the rotating screw 54 can be used to drive the load-bearing seat 51 to move up and down, which is used to change the height of the measuring needle 1. The up and down movement direction of the load-bearing seat 51 can be controlled by the different rotation directions of the screw 54.

[0031] In the embodiments of the present invention, please refer to Figure 1 , Figure 3 and Figure 4 A mounting frame 6 is provided on the pressure-conducting pipe A11, and bayonet holes 61 are provided at both ends of the mounting frame 6, and the pressure-conducting pipe A11 is located in the two bayonet holes 61. A mounting seat 63 is slidably connected in the mounting frame 6, and the top and bottom of the mounting seat 63 are rotatably connected to a limit rod 64. A screw rod 66 is threadedly connected on the mounting frame 6, and one end of the screw rod 66 is rotatably connected to the mounting seat 63, and the other end of the screw rod 66 is fixedly connected to a knob B67, and a roller 62 is rotatably connected in the bayonet holes 61, and the ends of the limit rods 64 are fixedly connected to magnet sheets 65.

[0032] It should be noted that: when using this device, the pressure-conducting pipe A11 is stuck in the bayonet 61, and then the limit rod 64 is rotated. The magnet sheet 65 at the end of the limit rod 64 is used to fix the ends of the two limit rods 64 to each other, and then the knob B67 is used to drive the screw rod 66 to rotate. The screw rod 66 will move when it rotates, and at this time, the mounting seat 63 rotatably connected to the screw rod 66 will move along the mounting frame 6 with the screw rod 66. At this time, the limit rod 64 can be used to retract the pressure-conducting pipe A11 into the mounting frame 6, so as to change the length of the pressure-conducting pipe A11. When the pressure-conducting pipe A11 is being retracted and pulled, the roller 62 can reduce the pressure and friction between the pressure-conducting pipe A11 and the mounting frame 6, so that the pressure-conducting pipe A11 will not affect the size of its inner diameter during the contraction process.

[0033] The working principle of the optic nerve sheath pressure monitor provided by the utility model is as follows:

[0034] First, the devices are connected in sequence, and then the pressure-conducting pipe A11 is clamped in the bayonet 61, and then the limiting rod 64 is rotated, and the ends of the two limiting rods 64 are fixedly connected to each other by using the magnet sheet 65 at the end of the limiting rod 64, and then the screw rod 66 is driven to rotate by the knob B67. When the screw rod 66 rotates, it moves, and at this time, the mounting seat 63 connected to the screw rod 66 will move along the mounting frame 6 with the screw rod 66. At this time, the limiting rod 64 can be used to shrink the pressure-conducting pipe A11 into the mounting frame 6, so as to change the length of the pressure-conducting pipe A11 and store the excess length of the pressure-conducting pipe A11;

[0035] Then, the measuring needle 1 is inserted into the optic nerve. At this time, the measuring needle 1 can be fixed by the fixing clamp 53, so that the measuring needle 1 is more stable during use. The deflection angle of the measuring needle 1 can be adjusted by rotating the mounting rod 52, and the screw rod 54 can be driven to rotate by turning the knob A55. At this time, the rotating screw rod 54 can be used to drive the bearing seat 51 to move up and down to change the height of the measuring needle 1.

[0036] Afterwards, the sterile liquid in the sterile barrel 4 is transported to the pressure-guiding pipe B21 and the pressure-guiding pipe A11 through the micro water pump 22. At this time, the anti-backflow solenoid valve B23 and the anti-backflow solenoid valve A12 can prevent the sterile liquid from flowing back. The optic nerve can block the sterile liquid due to the internal pressure. At this time, the electronic pressure sensor 2 can measure the pressure, and convert the measurement result into a real-time pressure signal by converting the electrical signal, and transmitting it to the display 3 through the data line. At this time, the display 3 presents the blood pressure value through the display 3 in the form of a waveform curve. Then, according to the pressure value, in combination with the imaging genomics data of the orbital HRCT, MRI and ultrasound of TON patients, the ETOCD surgical operation process is improved and optimized.
