[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example: Refer to Figure 1-5 , an otorhinolaryngology endoscope support, used for fixing an endoscope 5, comprising a mounting frame 1,

[0029] A fixing member is arranged on the mounting frame 1, and the fixing member includes a support frame 4 with one end connected to the mounting frame 1, and a fixing seat 2 is hingedly connected to the other end of the support frame 4. The fixing seat 2 is provided with a mounting hole, and the endoscope 5 is arranged in the mounting hole. The endoscope 5 is detachably connected to the fixing seat 2;

[0030] The auxiliary component is located on the fixed seat 2. The auxiliary component includes a plurality of auxiliary units arranged along the circumference of the mounting hole. The auxiliary units are used to assist the endoscope 5 in detection, and the plurality of auxiliary units have different auxiliary functions. One end of the plurality of auxiliary units extends along a side away from the fixed seat 2, and the endoscope 5 abuts against the plurality of auxiliary units.

[0031] The present invention uses an otorhinolaryngology endoscope 5 bracket to fix the endoscope 5. By providing mounting holes on the fixing base 2, the endoscope 5 is detachably connected within the mounting holes, and a corresponding auxiliary unit is provided on the fixing base 2. Through a number of different auxiliary units, a number of different auxiliary functions are correspondingly provided, thereby enhancing the functionality of the endoscope 5 for observing surgeries, expanding the applicable range of the endoscope 5 bracket. Moreover, the endoscope 5 is disposed within the mounting hole, and one end thereof extends out of the fixing base 2 and abuts against a number of auxiliary units. While assisting the endoscope 5 to be shaped to improve the observation accuracy, through a number of auxiliary units extending in a direction away from the fixing base 2, and the endoscope 5 abuts against a number of auxiliary units respectively, the endoscope 5 is fixed correspondingly by a number of auxiliary units, further ensuring the effective stability of the endoscope 5.

[0032] Further, one end of the auxiliary unit close to the fixing base 2 is fixedly connected to the fixing base 2. A functional area is provided on the auxiliary unit, and a functional component is installed within the functional area. One end of the functional component is connected to a functional part provided externally, and the other end of the functional component faces the endoscope 5.

[0033] Refer to Figure 1-2 , in this technical solution, the auxiliary unit is a support structure for correspondingly arranging functional components. Specifically, during the conventional otorhinolaryngology surgery process, for the detection of the endoscope 5 within the oral cavity, nasal cavity, and ear cavity, the functional component is preferably but not limited to a contrast device for assisting the shaping of the endoscope 5, a suction device for sucking the squeezed liquid within the cavity, a cleaning device for cleaning the cavity, and a drug delivery device for delivering drugs to the corresponding area within the cavity for treatment. By circumferentially arranging at least four auxiliary units, the functional component is thus stabilized, ensuring a clear division of the functional area and the effective operation of the corresponding device, and cooperating to improve the fixing effect on the endoscope 5 and ensure the imaging detection accuracy.

[0034] Further, the auxiliary unit includes a fixing rod 6. A number of collar rings 7 are successively fixedly connected to the fixing rod 6. The fixing rod 6 is a bendable structure. The functional component successively passes through the collar rings 7 and is fixedly connected to the fixing rod 6. One end of the functional component close to the fixing base 2 passes through the fixing base 2. The ends of a number of fixing rods 6 away from the fixing base 2 are distributed in a circumferential shape coaxially with the mounting hole. One end of the endoscope 5 extends out of the fixing base 2 and abuts against a number of fixing rods 6. An adjusting component is provided within the fixing base 2, and the endoscope 5 is detachably connected to the adjusting component.

[0035] Correspondingly, a transport pipe 8 is provided for the above-mentioned imaging, aspiration, cleaning, and drug delivery devices. One end of the transport pipe 8 sequentially passes through a number of sleeves 7 and is fixed on a fixed rod 6. The other end of the transport pipe 8 is correspondingly connected to a supply device (not shown in the figure). After the endoscope 5 extends into the cavity, the supply device is controlled externally to complete the auxiliary functions through the transport pipe 8. The supply of imaging, aspiration, cleaning, and drug delivery in this patent through the transport pipe 8 is prior art and will not be elaborated further. Preferably but not necessarily, the fixed rod 6 adopts a wire or a connecting rod structure with a damping rotating end, which is convenient for medical staff to adjust the angle in a timely manner during the detection of the endoscope 5. Corresponding to the detection end of the endoscope 5, while the circumferentially arranged fixed rod 6 provides multiple functional areas, it can also effectively expand the cavity and improve the convenience of observing with the endoscope 5.

[0036] Further, the adjusting member includes an installation sleeve 3 provided in the fixed seat 2. The installation sleeve 3 is slidably connected to the fixed seat 2. An installation hole is opened on the installation sleeve 3, and both ends of the installation hole penetrate through the installation sleeve 3 and are coaxially arranged with the installation sleeve 3. One end of the fixed rod 6 is fixedly connected to the installation sleeve 3. A communication hole is correspondingly opened on the installation sleeve 3 corresponding to the fixed rod 6. One end of the functional member penetrates through the communication hole. A connecting member is provided on the side wall surface of the fixed seat 2, and one end of the connecting member penetrates through the installation sleeve 3 and abuts against the endoscope 5.

[0037] By opening an empty groove in the fixed seat 2, the installation sleeve 3 is arranged in the empty groove and slidably connected to the fixed seat 2. The installation hole is opened on the installation sleeve 3, and a communication hole is correspondingly opened on the installation sleeve 3 on the outer peripheral side of the installation hole corresponding to the fixed rod 6, which is convenient for passing the transport pipe 8 through the communication hole and fixing it on the fixed rod 6. And one end of the connecting member extends into the fixed seat 2 and penetrates through the installation sleeve 3. When the bracket is not in use, the installation sleeve 3 can be disassembled through the connecting member for cleaning and maintenance.

[0038] Further, the connecting member includes a connecting plate 9 integrally formed with the fixed seat 2. A groove is correspondingly opened on the outer wall surface of the installation sleeve 3 and the connecting plate 9. A rubber pad 14 is fixedly connected to the inner wall of the bottom end of the groove. One end of the connecting plate 9 abuts against the rubber pad 14. A threaded hole is opened on the connecting plate 9, and an adjusting bolt 10 is threadedly connected in the threaded hole. One end of the adjusting bolt 10 extends into the installation sleeve 3, and a buffer member is arranged in the installation sleeve 3. One end of the buffer member abuts against the endoscope 5.

[0039] By rotating the adjusting bolt 10, one end of the adjusting bolt 10 extends into the installation sleeve 3 and abuts against the buffer member, so that the buffer member abuts against the endoscope 5. By the combined action of the rubber pad 14 and the buffer member, the influence of the vibration generated by the external force on the endoscope 5 is reduced, and the service life of the device is improved.

[0040] Furthermore, the buffer member includes a limit plate 11 which is slidably connected with the mounting sleeve 3. One end of the adjusting bolt 10 extends into the mounting sleeve 3 and abuts against one side of the limit plate 11. A buffer pad 13 is fixedly connected to the other side of the limit plate 11. A limit member is provided on the inner wall surface of the mounting sleeve 3 corresponding to the limit plate 11. The limit member is used to cover the inner wall surface of the mounting sleeve 3.

[0041] Furthermore, the limiting member includes a limiting sleeve 15 fixedly connected to the mounting sleeve 3, the limiting sleeve 15 is arranged in the mounting hole, a slot is provided on the inner wall surface of the mounting sleeve 3, a clamping block 16 is fixedly connected to one end of the limiting sleeve 15, the clamping block 16 is clamped in the slot, a sliding groove is provided in the clamping block 16, the limiting plate 11 is arranged in the sliding groove, a plurality of limiting slide rails 12 are fixedly connected on both sides of the limiting plate 11, limiting grooves are provided on the inner wall surface of the sliding groove corresponding to the limiting slide rails 12, and the limiting slide rails 12 are slidingly connected with the limiting grooves.

[0042] Reference Figure 1 When the adjusting bolt 10 is extended into the mounting sleeve 3, it passes through the block 16 and slides with the limiting plate 11 in the limiting sleeve 15. Under the action of the limiting slide rail 12, the limiting plate 11 moves along the slide groove until it abuts against the endoscope 5 to fix it. After the imaging is completed, the adjusting bolt 10 is reversed so that the limiting plate 11 does not abut against the endoscope 5, and the endoscope 5 is removed from the mounting hole, so as to improve the actual use effect during the treatment observation process.

[0043] Furthermore, the mounting frame 1 includes two relatively arranged mounting plates 101 and a clamping plate 102, and a limiting screw 103 is transferred to the mounting plate 101. One end of the limiting screw 103 extends out of the mounting plate 101 and is threadedly connected to the clamping plate 102. One end of the support frame 4 is transferred to the mounting plate 101. The mounting plate 101 and the support frame 4 are correspondingly provided with driving components, and the driving component is transmission-connected to the mounting frame 1.

[0044] By setting the limiting screw 103, the mounting plate 101 and the clamping plate 102, it is convenient to fix the overall endoscope 5 bracket in a specific area for observation and treatment during actual work. The driving member assists the support frame 4 to rotate, thereby controlling the movement of the endoscope 5 on the fixed seat 2, thereby reducing the workload of medical staff.

[0045] Furthermore, the driving component includes a motor plate 18 fixedly connected to the mounting plate 101, a servo motor 19 fixedly connected to the motor plate 18, an output shaft of the servo motor 19 fixedly connected to a gear 20 through a coupling, an adapter seat 402 is provided on the side of the support frame 4 close to the mounting plate 101, two ends of a rotating rod 22 are connected between the adapter seat 402 and the mounting plate 101, and gear teeth 21 are fixedly connected to the outer wall surface of the adapter seat 402, and the gear teeth 21 are meshed with the gear 20.

[0046] Further, the support frame 4 includes an electric push rod 401. One end of the electric push rod 401 close to the adapter seat 402 is fixedly connected with a ball hinge 403. The adapter seat 402 is correspondingly provided with a ball hinge groove for the ball hinge 403. The other end of the electric push rod 401 is hinged to one side of a base 404 through a hinge shaft, and the other side of the base 404 is detachably connected to the fixed seat 2.

[0047] When adjusting the observation position of the endoscope 5, start the servo motor 19 to drive the adapter to rotate. At the same time, the electric push rod 401 moves the base 404, so that the fixed seat 2 connected to the base 404 by bolts moves for the detection of the endoscope 5. During the observation of the surgical process, the staff can hold the rotary handle 17 and control the fixed seat 2 to perform fine position adjustment in the narrow area through the cooperation of the ball hinge 403 groove and the hinge shaft, reducing the labor intensity of the medical staff while improving the flexible mobility of the endoscope 5.
