Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to an otolaryngology endoscope bracket. Background Art

[0002] As an important optical device in the otolaryngology department, ENT endoscope can conduct in-depth and detailed examination of the nasal cavity, throat and ears. In the actual operation process, medical staff need to hold the endoscope and support it stably throughout the whole process. The continuous occupation of the medical staff's hands greatly limits the flexibility of operation and brings many inconveniences to the inspection work. In addition, long-term holding of the endoscope can easily cause fatigue to the medical staff, affecting the accuracy and efficiency of the inspection. Therefore, it is generally used to fix and support the endoscope with the help of an endoscope stand, thereby effectively freeing the hands of medical staff.

[0003] At present, the endoscope bracket mainly relies on the clamping plate at the bottom to clamp the work surface to ensure stable placement. However, during the fixing process, it is usually necessary to manually tighten the bolts to drive the clamping plate to move in order to clamp the work surface. This operation is not only labor-intensive, but also difficult to accurately control the clamping force. If the clamping force is too large, it may damage the clamping plate and the work surface; if the clamping force is too small, stable clamping cannot be guaranteed, affecting the use of the equipment.

[0016] Compared with the existing technology, the advantages of an otolaryngology endoscope bracket are: 1. The driving unit, clamping monitoring unit and PLC controller work together to achieve precise control of the clamping force. The micro servo motor drives the worm gear to drive the lead screw to rotate, so that the lower clamping plate moves smoothly. During the clamping process, the flexible pressure sensor monitors the clamping pressure in real time and feeds the signal back to the PLC controller. When the clamping force reaches the preset value, the PLC controller can shut down the micro servo motor in time to avoid excessive clamping force that damages the equipment or work surface, and prevents the clamping force from being too small and causing unstable fixation. Compared with the traditional manual bolt tightening clamping method, the clamping accuracy and safety are greatly improved.

[0017] 2. Through the dust removal unit, before clamping, the micro air pump sprays gas through the air guide cavity and the dust removal hole inclined at 45 degrees, which can deal with dust particles on the bottom of the load-bearing workbench that are difficult to clean manually. It not only reduces the tedious operation of manual cleaning, but also provides a good clamping environment for the lower clamping plate, reduces the impact of dust on the clamping stability and equipment wear, and, during clamping, the airflow ejected from the dust removal hole forms an air cushion layer, which alleviates the rigid contact between the lower clamping plate and the workbench, and further protects the equipment and the workbench.

[0018] 3. The clamping stability of the bracket is enhanced by the cooperation of the suction unit and the power control unit. The electromagnetic plate and the permanent magnet sheet cooperate with each other to provide additional magnetic suction assistance during the clamping process, sharing the load-bearing load of the screw. Moreover, as the lower clamping plate rises, the power control unit will automatically adjust the resistance value in the electromagnetic plate circuit according to the change in the distance between the electromagnetic plate and the permanent magnet sheet, so that the magnetic suction assistance is always maintained within an appropriate range. This magnetic suction assistance and mechanical clamping force form a double guarantee, which effectively prevents the bracket from shifting or falling off due to vibration, external force collision and other factors during use, ensuring the stability of the endoscope during inspection or surgery.

[0019] 4. The angle adjustment unit, fixing unit, electric slide rail, drive motor and other components are set to make the adjustment of the endoscope more flexible and convenient. The combination of the rolling ball and the rolling groove allows the fixing frame to be adjusted at multiple angles to meet the needs of different inspection or surgical scenarios. The micro electric push rod controls the arc-shaped rubber clamp to accurately lock the endoscope body, and the two fixing units improve the stability of the locking. The electric slide rail and drive motor respectively realize the lateral displacement and horizontal angle adjustment of the fixing frame, which is convenient for medical staff to quickly adjust the position of the endoscope and improve work efficiency.

[0020] 5. By setting up a locking maintenance monitoring unit, it is convenient for medical staff to lock the ball in the angle adjustment unit in real time, and can monitor the use of the angle adjustment unit. When the angle adjustment unit needs to be maintained, the PLC controller controls the maintenance sound and light prompt to start, giving medical staff a reminder, avoiding the uncertainty and tediousness of manual judgment of the timing of ball maintenance, and promptly reminding medical staff to lubricate and maintain the ball connection parts to ensure the normal use of the commonly used angle adjustment units, so that the locking maintenance monitoring unit realizes the dual functions of precise locking of angle adjustment and intelligent monitoring of the angle adjustment unit.

This is a prior art and will not be elaborated on.

[0034] The operating principle of the present invention is now described as follows: When using the present bracket, first clean the upper surface of the workbench which is easy to clean, then insert the workbench between the L-shaped clamp seat 2 and the lower clamp plate 5, and make the upper part of the L-shaped clamp seat 2 press the cleaned surface of the workbench, then turn on the power supply [the power supply method can use an external power supply or configure a battery on the bracket, which is a prior art and will not be elaborated on here]. Subsequently, the micro servo motor 62, the micro air pump 71, the electromagnetic plate 91 and the arc-shaped electromagnetic block 142 are controlled by the PLC controller 3 to start. After the micro servo motor 62 is started, it will control the worm 63 to rotate. Under the transmission cooperation of the two worm wheels 64, the two lead screws 4 can rotate synchronously, so that both sides of the lower clamp plate 5 can be stably stressed. During the upward movement, the magnetic force between the electromagnetic plate 91 and the permanent magnetic sheet 92 will pass through the plate surface of the bearing workbench to attract each other, and the magnetic attraction of the permanent magnetic sheet 92 provides additional assistance for the upward movement of the lower clamping plate 5, sharing part of the workload of the micro-servo motor 62 and the lead screw 4, and extending the service life of the two. As the lower clamping plate 5 gradually moves upward, the lower clamping plate 5 will drive the sliding end of the sliding rheostat 102 to move upward through the insulating slider 19, so that the resistance of the sliding rheostat 102 connected to the circuit of the electromagnetic plate 91 gradually increases, and the magnetic force of the electromagnetic plate 91 is correspondingly weakened, so as to adapt to the reduction of the distance between the permanent magnetic sheet 92 and the electromagnetic plate 91, and ensure that the magnetic attraction between the two is always maintained in an appropriate range; During the upward movement of the lower clamping plate 5, the micro air pump 71 will guide the external air to the three-way pipe 16 through the corrugated telescopic tube 17. A filter screen can be set at the input end of the micro air pump 71 to prevent dust from being sucked in. The three-way pipe 16 will divert the airflow to the air guide cavity 72 and the dust removal seat 74, and spray it out through each dust removal hole 73 and the dust removal port 31. The airflow sprayed through the dust removal hole 73 will blow away the dust particles on the bottom surface of the workbench that are not easy to clean as much as possible, thereby reducing the wear of the lower clamping plate 5 by dust particles when the lower clamping plate 5 is clamped later. The dust removal holes 73 are arranged outwardly at an angle of 45 degrees, so that the dust particles can be blown away from the outside of the lower clamping plate 5. At the same time, under the action of the airflow generated by the dust removal ports 31 of the dust removal seat 74, the dust particles can be further blown out of the lower clamping plate 5, thereby reducing the tedious operation of manually cleaning the bottom surface of the workbench. When the lower clamping plate 5 clamps the worktable, the air cushion layer formed by the dust removal hole 73 can relieve the rigid contact between the lower clamping plate 5 and the worktable. When the clamping force reaches the preset value, the flexible pressure sensor 82 in the clamping monitoring unit 8 will feedback an electrical signal to the PLC controller 3. After receiving the signal, the PLC controller 3 immediately controls the micro servo motor 62 and the micro air pump 71 to stop working, thereby automatically terminating the clamping action to ensure that the clamping force is within an appropriate range. Under the magnetic suction assistance of the permanent magnet sheet 92 and the electromagnetic plate 91, the screw 4 can be shared. The load-bearing load, the mechanical clamping force generated by the magnetic suction power and the lower clamping plate 5 and the L-shaped clamping seat 2 cooperate with each other to ensure the stability of the clamping. Compared with the simple clamping by mechanical force, it may be loose due to vibration, external force collision and other factors. The magnetic suction power generated can make the lower clamping plate 5 and the L-shaped clamping seat 2 attract each other, and form a double guarantee with the mechanical clamping force between the clamps, which greatly improves the fixing effect of the endoscope bracket on the workbench, prevents displacement or falling off during use, and ensures that the endoscope maintains a stable position during inspection or surgery; Subsequently, the endoscope body shell is inserted into the two sockets 151, and then the PLC controller 3 controls the movement of each micro electric push rod 152. The program preset by the PLC controller 3 controls the extension length of the micro electric push rod 152, so that each arc-shaped rubber clamp 153 can firmly clamp the endoscope body shell. After the endoscope is fixed, the electric slide rail 25 can be used to achieve the lateral displacement adjustment required during the use of the endoscope. The drive motor 27 drives the swivel seat 28 to rotate, thereby driving the support rod 11 and the fixing frame 13 to rotate, so as to achieve the endoscope. Horizontal angle adjustment of the endoscope. When the pitch angle of the endoscope needs to be adjusted, the operator cuts off the current of the arc-shaped electromagnetic block 142 through the PLC controller 3 to unlock the ball 122 in the angle adjustment unit 12. At this time, the operator can adjust the angle of the fixed frame 13 through the ball 122. When the lens of the endoscope is accurately extended into the detection part, the arc-shaped electromagnetic block 142 is energized again through the PLC controller 3 to generate magnetic attraction to the ball 122, thereby locking the position of the endoscope to ensure that the endoscope can remain stable during the inspection or operation; During daily use, the ball 122 continuously rolls and squeezes the arc-shaped electromagnetic block 142. With the cooperation of the reset spring 22, the ceramic piezoelectric piece 143 in the sensing cavity 23 supporting the slider 141 is subjected to the vibration force. The ceramic piezoelectric piece 143 converts the vibration force into a tiny electrical signal, which is amplified by the electrical signal amplifier 144 and then fed back to the PLC controller 3. The PLC controller 3 continuously monitors the duration of the electrical signal generation. When it is detected that the total duration of the electrical signal generated by the electrical signal amplifier 144 reaches a preset threshold, the PLC controller 3 starts the maintenance sound and light reminder 24 to remind medical staff to lubricate and maintain the connection parts of the ball 122 in time, so as to avoid the uncertainty and tediousness of manually judging the maintenance timing of the ball 122 and ensure the normal operation of the ball 122.
