Description

Technical Field

[0001] The invention relates to the technical field of nursing equipment, and in particular to an adjustable supporting device for otorhinolaryngology and head and neck surgery. Background Art

[0002] Otorhinolaryngology and head and neck surgery requires high neck stability. In otolaryngology and head and neck surgery, accurate and stable positioning and support of the patient's neck is the key to ensure the smooth progress of the operation. For example, the master's thesis of the University of South China, "Analysis of Related Factors of Difficult Exposure of Laryngopharyngeal Cavity under Indirect Laryngoscope", was published online in 2018. The good exposure of the laryngopharyngeal cavity analyzed is conducive to the accurate diagnosis of laryngopharyngeal cavity diseases, the smooth progress of surgical operations, and the reduction of intraoperative and postoperative complications. Therefore, the prediction of poor exposure of the laryngopharyngeal cavity is extremely important for the selection and smooth progress of surgical methods; in addition, more common surgeries such as thyroid surgery and laryngeal cancer resection also require precise exposure of the surgical field.

[0003] However, in the prior art, most support devices have difficulty in accurately controlling the angle and posture of the patient's neck when adjusting it, especially when the neck operating area needs to be adjusted to a horizontal state, which is usually difficult to do. Existing devices may include traditional headrests, adjustable support frames, and robotic arm systems. The problem with traditional fixed headrests is that they are not adjustable, and the adjustable support frame may only have single-axis adjustment. Although the multi-axis robotic arm system is accurate, it is costly and complicated to operate, such as Mizuho OSI Armored (orthopedic operating table), which is mainly used for overall control of the whole body. When it comes to otolaryngology, head and neck, the cost is too high. Therefore, it is difficult to ensure that the patient's neck is stable in an ideal state compared to conventional solutions. Especially during surgery, when it is necessary to accurately expose the surgical area, the instability or incorrect posture of the neck will affect the surgical field of view and increase the difficulty and risk of medical staff's operation.

[0004] For example, the U.S. invention patent US20200100973A1 discloses a patient support structure for supporting a patient in a supine position for surgery and a method for using the patient support structure, and the Chinese invention patent CN109953864B discloses an auxiliary support device for pharyngeal head and neck surgery. In the above device, when adjusting the head and neck, a head fixing plate or a fixing belt is used to perform a simple clamping operation on the patient's head, so as to achieve the purpose of limiting the patient's head; when adjusting the patient's neck, only a simple supporting operation can be performed on the patient's neck, and the adjustment angle is limited and the accuracy is poor; although the basic angle adjustment function is provided, due to the lack of precise adjustment mechanism and stable support structure, the patient's neck often rotates or tilts unnecessarily during operation. This unstable posture not only hinders the surgical operation of medical staff, but also may cause accidental stretching or damage to the neck tissue, affecting the surgical effect. There is also a problem of insufficient three-dimensional space adjustment ability, which cannot meet the influence of differences between different patients in clinical practice, and the problem of intraoperative adjustment interfering with the surgical process. Summary of the invention

[0005] 1. Technical issues to be solved

[0009] Furthermore, in order to better fix the patient's head, the head limiting device also includes a supporting unit for supporting the patient's head; the supporting unit is vertically arranged on the movable supporting frame, and the supporting unit is centrally arranged at one end of the movable supporting frame away from the fixed supporting frame; the adjusting unit is vertically arranged on one side of the supporting unit; and the adjusting unit is provided with a first limiting component and a second limiting component that can be capable of approaching or moving away from the patient's head.

[0010] In order to further increase the adjustable range, the supporting unit includes a supporting portion for supporting the patient's head; and the supporting portion can be longitudinally adjusted according to supporting requirements.

[0011] In combination with the first aspect, in order to achieve more convenient angle adjustment, the adjustment unit also includes a guide ring capable of guiding the first limit assembly and the second limit assembly to rotate circumferentially along the supporting unit; and a synchronous adjustment frame capable of synchronously driving the first limit assembly and the second limit assembly to adjust along the axis of the guide ring; the synchronous adjustment frame is coaxially rotatably arranged in the guide ring, and the two ends of the synchronous adjustment frame are respectively fixedly connected to the first limit assembly and the second limit assembly; the guide ring is vertically fixed on the fixed supporting frame through the first mounting frame, that is, the guide ring can act as a guide rail.

[0012] On the second aspect, in order to achieve better support for the patient's head, the first limiting assembly includes a second sliding frame, a second guide rod, a second telescopic frame, a limiting rod, a second locking bolt and a third locking bolt; the second sliding frame is slidably arranged in the guide ring; the second guide rod is centrally and vertically arranged on the second sliding frame; the second telescopic frame is slidably sleeved outside the second guide rod; the limiting rod is hingedly arranged at the front end of the second telescopic frame; the second locking bolt is threadedly arranged outside the second sliding frame to lock the second sliding frame adjusted to the sliding stroke; the third locking bolt is threadedly arranged on one side of the front end of the second telescopic frame to limit and fix the limiting rod adjusted to the limiting angle.

[0013] On the basis of fixing the head, corresponding support also needs to be provided for the neck. Specifically, the neck support device includes a supporting part for longitudinally supporting the patient's neck and an adjusting component that can adjust the supporting position and height of the supporting part. Further, the adjusting component includes a guide rod, a driving screw, a driving knob, a slide rail and a slide plate; there are two groups of slide rails, and the two groups of slide rails are fixedly arranged on the lower surface of the movable support frame in parallel along the long side direction of the movable support frame; the slide plate is arranged across the two groups of slide rails and slidingly cooperates with the two groups of slide rails; the guide rod and the driving screw are relatively vertically arranged on the lower surface of the supporting part, and the connection between the driving screw and the supporting part is rotatably connected; the rod parts of the guide rod and the driving screw are both arranged through the slide plate, the guide rod is slidingly cooperated with the slide plate, and the driving screw is threadedly cooperated with the slide plate; the driving knob is fixedly arranged at the end of the driving screw away from the supporting part.

[0014] In combination with the second aspect, a first limiting plate and a second limiting plate are further provided on the movable supporting frame, which can limit the patient's two sides respectively; the first limiting plate and the second limiting plate are arranged parallel to the long side direction of the movable supporting frame on both sides of the movable supporting frame.

[0015] In the third aspect, the inclination control and corresponding driving of the movable bracket are performed through an angle adjustment device, and the angle adjustment device includes a first linear drive and a second linear drive that can respectively adjust the inclination angles of both sides of the movable bracket.

When the first linear drive and the second linear drive on the same side are synchronously driven, and / or the first linear drive and the second linear drive on the same side are synchronously driven, the first movable frame and the second movable frame are synchronously tilted in one direction as a whole.

[0017] In certain implementations of the third aspect, in order to further achieve hyperextension of the patient's neck to achieve a better surgical field display, the connection between the second linear drive and the second movable frame is close to the hinge of the first movable frame and the second movable frame. When the second linear drive is driven synchronously, the hinge of the first movable frame and the second movable frame is pushed upward, thereby achieving more dimensional adjustment and support for the patient.

[0018] Optionally, the guide ring is vertically fixed on the fixed supporting frame through a first mounting frame.

[0019] Alternatively, in order to further reduce the patient's discomfort, the guide ring is hinged to the first mounting frame via a damping shaft.

[0040] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0041] Embodiment 1:

[0042] like Figure 1 , Figure 3 As shown, the adjustable support device for otolaryngology and head and neck surgery of this embodiment is used to support and adjust the head and neck of a patient, and includes: a base frame 1; a fixed support frame 2, which is horizontally fixedly arranged on the base frame 1; a movable support frame 3, which is horizontally rotatably arranged at one end of the fixed support frame 2; a neck support device 4, which is arranged on the movable support frame 3 and is located at the end away from the fixed support frame 2; a head limiting device 5, which is arranged on the movable support frame 3 and is located on the side of the neck support device 4 away from the fixed support frame 2; the head limiting device 5 is provided with an adjustment unit 51 for tilting the patient's head; and a detection unit 52 for real-time detection of the adjustment angle of the patient's head; an angle adjustment device 6, which is fixedly arranged on the base frame 1 in an inclined state and the adjustment end is hinged to the adjustment end of the movable support frame 3.

[0043] When a surgical operation is required on the patient's neck, the patient is first laid flat on the fixed support frame 2 and the movable support frame 3, with the patient's waist located between the fixed support frame 2 and the movable support frame 3, and the buttocks located on the fixed support frame 2. Then, the patient's neck and head are respectively arranged on the neck support device 4 and the head limit device 5. Next, according to the requirements of the surgical operation, if the patient's head and neck need to be twisted at a certain angle, the patient's head and neck are first precisely limited and fixed by the neck support device 4 and the head limit device 5 to ensure that no unnecessary deviation occurs. Then, the head limit device 5 is driven to make precise angle adjustments in the required direction to twist the patient's head to a predetermined angle.

[0044] In this process, if Figure 2 As shown, the detection unit 52 monitors the torsion angle of the head in real time, and synchronously transmits the data to the control unit of the device, and controls the angle adjustment device 6 through the control unit. The angle adjustment device 6 automatically adjusts the movable support frame 3 according to the detected angle signal to keep it consistent with the angle of the head. Since the patient's neck is placed between the head and the upper body, the synchronous adjustment of the head and the upper body ensures the accurate synchronous adjustment of the neck angle, avoids unnecessary twisting or spraining of the neck caused by independent twisting, thereby effectively ensuring the stability of the neck, and facilitating medical staff to perform precise surgical treatment during the operation.

[0045] By transferring the twisting operation that would have directly acted on the neck to the waist and adjusting it synchronously, the problem of neck injury or strain caused by excessive twisting is avoided. At the same time, the stability of the patient's neck during the operation is ensured by the precise angle adjustment mechanism, and the stability and convenience of operation during the operation are enhanced. Therefore, the adjustment action of the neck is transferred to the patient's waist through the cooperation of the movable support frame 3, the head limit device 5 and the angle adjustment device 6, so that the pathological area of ​​the patient's neck is always kept stable and horizontally set upward during the operation, which is very convenient for maintaining the surgical field. That is, the neck originally needed to be twisted to a certain angle during the operation to maintain the doctor's good field of vision during the operation. Now, only a preliminary twist needs to be performed in advance through the head limit device 5. The angle adjustment device 6 monitors the twisting angle of the head according to the detection unit 52, and performs a reverse angle rotation to drive the body to twist a certain angle. At this time, the patient's head is synchronously rotated to the state facing upward at the head limit device 5. At the same time, due to the twisting of the body, an angle synchronization compensation effect is achieved, which does not affect the surgical field and is more convenient for the doctor to perform the operation.

[0046] like Figure 2 , Figure 4 and Figure 7As shown, the head limiting device 5 also includes a supporting unit 53 for supporting the patient's head; the supporting unit 53 is vertically arranged on the movable supporting frame 3, and the supporting unit 53 is centrally arranged at one end of the movable supporting frame 3 away from the fixed supporting frame 2; the adjusting unit 51 is vertically arranged on one side of the supporting unit 53; and the adjusting unit 51 is provided with a first limiting component 511 and a second limiting component 512 that can move closer to or away from the patient's head.

[0047] After the patient lies flat on the fixed support plate and the movable support plate, when the patient's head needs to be limited and fixed, the medical staff first places the patient's head on the supporting element, thereby supporting the patient's head through the supporting element; after the patient's head is placed in the correct position, when the left and right inclination angles of the patient's head need to be adjusted according to the surgical requirements, the adjustment unit 51 is driven to operate, and the first limiting component 511 and the second limiting component 512 in the adjustment unit 51 are used to limit and support the two sides of the patient's temples respectively, so as to achieve the purpose of limiting and fixing the patient's head, finally, the adjustment unit 51 is driven to operate to adjust the patient's head to the desired angle and then the adjustment unit 51 is locked.

[0048] like Figure 5 , Figure 8 As shown, the supporting unit 53 includes a supporting portion 531 for supporting the patient's head; and the supporting portion 531 can adjust the support height according to the supporting requirements. Specifically, the supporting unit 53 also includes a first sliding frame 532, a first guide rod 533, a first locking bolt 534 and a first telescopic frame 535; the first sliding frame 532 is slidably set in the guide ring 513 and is set on one side of the guide ring 513; the first guide rod 533 is centrally and vertically set on the first sliding frame 532; the first telescopic frame 535 is centrally and vertically set on the outer side of the supporting portion 531; the supporting portion 531 is slidably set outside the first guide rod 533 through the first telescopic frame 535; the first locking bolt 534 is screwed on the outer wall of the first telescopic frame 535, so as to lock the first telescopic frame 535 adjusted to the desired position.

[0049] When the support height needs to be adjusted according to the head size of different patients, the medical staff first loosens the first locking bolt 534 to release the limiting function of the first telescopic frame 535 to ensure that the first telescopic frame 535 can be freely adjusted. Then, the medical staff adjusts the longitudinal position of the supporting part 531 according to the current head size of the patient to ensure that the patient's head is fully supported at an appropriate height. After the adjustment is completed, the medical staff re-tightens the first locking bolt 534 to ensure that the first telescopic frame 535 is firmly locked in the predetermined position, thereby fixing the height of the supporting part 531 to prevent unnecessary displacement or adjustment during use.

[0050] like Figure 8 and Fig.10 As shown, the adjustment unit 51 also includes a guide ring 513 capable of guiding the first limit assembly 511 and the second limit assembly 512 to rotate circumferentially along the supporting unit 53; and a synchronous adjustment frame 514 capable of synchronously driving the first limit assembly 511 and the second limit assembly 512 to adjust along the axis of the guide ring 513; the synchronous adjustment frame 514 is coaxially rotatably arranged in the guide ring 513, and the two ends of the synchronous adjustment frame 514 are respectively fixedly connected to the first limit assembly 511 and the second limit assembly 512, so that the first limit assembly 511, the second limit assembly 512 and the synchronous adjustment frame 514 can synchronously slide and rotate in the guide ring 513; in this embodiment, the guide ring 513 is vertically fixedly arranged on the fixed supporting frame 2 through the first mounting frame 515, and the second limit assembly 512 and the first limit assembly 511 have the same structure.

[0051] When the tilt angle of the patient's head is precisely adjusted according to the medical adjustment requirements, first, under the guidance of the medical staff, the patient's head is placed on the supporting part 531. At this time, the medical staff synchronously drives the first limit assembly 511 and the second limit assembly 512, and uses them to support the sideburns of the patient on both sides, respectively, to ensure that the patient's head is stably placed on the supporting part 531. Then, the medical staff adjusts the spacing between the first limit assembly 511 and the second limit assembly 512 according to the patient's head diameter, so that it matches the size of the patient's head, ensuring that the patient's head is in an ideal position and stably fixed. After completing this adjustment, operate the synchronous adjustment frame 514 to drive the first limit assembly 511 and the second limit assembly 512 to synchronously tilt and adjust until the tilt angle of the patient's head is adjusted to the desired precise angle. Not only that, the surgical field of view can be adjusted multiple times during the operation, and the adjustment process is simple and efficient, ensuring that the patient's head is always at the best angle during the operation.

[0052] like Figure 8 As shown, the first limiting assembly 511 includes a second sliding frame 5111, a second guide rod 5112, a second telescopic frame 5113, a limiting rod 5114, a second locking bolt 5115 and a third locking bolt 5116; the second sliding frame 5111 is slidably arranged in the guide ring 513; the second guide rod 5112 is centrally and vertically arranged on the second sliding frame 5111; the second telescopic frame 5113 is slidably sleeved outside the second guide rod 5112; the limiting rod 5114 is hingedly arranged at the front end of the second telescopic frame 5113; the second locking bolt 5115 is screwed outside the second sliding frame 5111 to lock the second sliding frame 5111 adjusted to the sliding stroke; the third locking bolt 5116 is screwed on one side of the front end of the second telescopic frame 5113 to limit and fix the limiting rod 5114 adjusted to the limiting angle.

[0053] When the medical staff needs to accurately limit and fix the patient's head through the first limiting assembly 511 to achieve the angle adjustment of the head, first drive the second locking bolt 5115 and the third locking bolt 5116 to release the restrictions on the second telescopic frame 5113 and the limiting rod 5114 respectively. Then, according to the limiting requirements, the medical staff slides and adjusts the limiting rod 5114 and the second telescopic frame 5113 to the required limiting position and angle. Since the limiting rod 5114 is hingedly arranged at the front end of the second telescopic frame 5113, it has a large degree of freedom in angle adjustment, so that the limiting rod 5114 can be adjusted to the required angle according to different surgical requirements. After the adjustment is completed, the medical staff re-tightens the second locking bolt 5115 and the third locking bolt 5116 to lock the second telescopic frame 5113 and the limiting rod 5114 to ensure the stability and precise positioning of the patient's head during the entire operation. This can provide medical staff with greater adjustment flexibility while ensuring that the patient's head always remains at the optimal angle and position, that is, before preparing for surgery, the above structure is preoperatively adjusted according to the patient's body size.

[0054] Embodiment 2:

[0055] Compared with Example 1, Figure 6 and Fig.10 As shown, the neck support device 4 includes a support portion 41 for longitudinally supporting the patient's neck and an adjustment component 42 capable of adjusting the support position and height of the support portion 41. The support portion 41 is an arc-shaped pillow adapted to the patient's neck. The support portion 41 is used to longitudinally support the patient's neck, so that the patient's neck can be freely adjusted to a desired height and position according to surgical requirements.

[0056] like Figure 6 As shown, the adjustment component 42 includes a guide rod 421, a driving screw 422, a driving knob 423, a slide rail 424 and a slide plate 425; the slide rail 424 is provided with two groups, and the two groups of slide rails 424 are fixedly arranged on the lower surface of the movable supporting frame 3 in parallel along the long side direction of the movable supporting frame 3; the slide plate 425 is arranged across the two groups of slide rails 424 and slides with the two groups of slide rails 424; the guide rod 421 and the driving screw 422 are relatively vertically arranged on the lower surface of the top support part 41, and the connection between the driving screw 422 and the top support part 41 is rotationally connected; the rod parts of the guide rod 421 and the driving screw 422 are both arranged through the slide plate 425, the guide rod 421 and the slide plate 425 are slidingly matched, and the driving screw 422 and the slide plate 425 are threadedly matched; the driving knob 423 is fixedly arranged at the end of the driving screw 422 away from the top support part 41.

[0057] When the height of the patient's neck support needs to be adjusted according to surgical requirements, the medical staff can operate by holding the driving knob 423. When the driving knob 423 is rotated, the driving screw 422 will drive the top support part 41 to perform precise longitudinal adjustment along the axial direction of the guide rod 421. This adjustment process can flexibly adjust the height of the support part according to the neck characteristics of different patients to meet different treatment or surgical requirements.

[0058] like Figure 5 As shown, the detection unit 52 is an angle sensor. By adopting the angle sensor, the adjustment angle of the adjustment unit 51 can be accurately detected in real time. The angle sensor monitors the real-time angle change of the adjustment unit 51 through a high-precision sensor, and synchronously transmits these data to the control part of the device, and controls the angle adjustment device 6 through the control part. The angle adjustment device 6 synchronously adjusts the movable carrier 3 according to the received real-time detection data to ensure that the movable carrier 3 always remains within the predetermined angle range.

[0059] like Figure 2 and Fig. 9 As shown, the angle adjustment device 6 includes a first linear driver 61 and a second linear driver 62 which can respectively adjust the tilt angles of the two sides of the movable support frame 3. Specifically, the angle adjustment device 6 includes a first linear driver 61a, 61b and a second linear driver 62a, 62b which can respectively adjust the tilt angles of the two sides of the movable support frame 3. The angle adjustment device 6 also includes a first hinge part 63 and a second hinge part 64; the first linear driver 61 and the second linear driver 62 are respectively hinged to the bottom of the base frame 1 through the first hinge part 63; the driving ends of the first linear driver 61 and the second linear driver 62 are respectively hinged to the lower surfaces of the two sides of the movable support frame 3 through the second hinge part 64.

[0060] The first linear driver 61 and the second linear driver 62 are connected to the detection unit 52 through signals. The system automatically starts the first linear driver 61 and / or the second linear driver 62 according to the angle signal of the detection unit 52. The first linear driver 61 and / or the second linear driver 62 drive the movable support frame 3 to perform precise adjustment, thereby adjusting the angle of the movable support frame 3 to ensure that the movable support frame 3 remains in the desired tilt state. The adjustment process can be automatically performed according to the surgical requirements or the real-time changes in the patient's head posture.

[0061] The present invention can not only effectively limit the position of the patient's head and neck but also accurately adjust the tilt angle of the head and neck.

[0062] Embodiment 3:

[0063] Compared with Example 1, Figure 2As shown: the movable supporting frame 3 is also provided with a first limiting plate 31 and a second limiting plate 32 which can limit the two sides of the patient respectively; the first limiting plate 31 and the second limiting plate 32 are arranged parallel to the two sides of the movable supporting frame 3 along the long side direction of the movable supporting frame 3.

[0064] In order to ensure that when the patient's head is tilted by the adjustment unit 51, the angle adjustment device 6 simultaneously adjusts the tilt angle of the movable support frame 3 to ensure that the patient has sufficient support in the tilted state, before adjusting the head tilt, it is necessary to first operate the first limit plate 31 and the second limit plate 32 to provide auxiliary support on both sides of the patient's upper body, so as to ensure that the patient's upper body remains stable during the tilting process, and avoid the patient from slipping due to the shift of the center of gravity when the adjustment angle is large. At the same time, the first limit plate 31 and the second limit plate 32 provide necessary support by closely contacting the two sides of the patient's upper body, ensuring that the patient's posture will not be excessively tilted or unstable, thereby ensuring his safety.

[0065] Embodiment 4:

[0066] Compared with Example 1, Figure 3 As shown, the movable supporting frame 3 includes a first movable frame 3a and a second movable frame 3b, the second movable frame 3b is located between the first movable frame 3a and the fixed supporting frame 2, and the first movable frame 3a and the second movable frame 3b are hinged.

[0067] The first linear drivers 61a and 61b are located at two sides of the bottom of the first movable frame 3a, and the second linear drivers 62a and 62b are located at two sides of the bottom of the second movable frame 3b.

[0068] When the first linear drive 61a and the second linear drive 62a on the same side are driven synchronously, and / or the first linear drive 61b and the second linear drive 62b on the same side are driven synchronously, the first movable frame 3a and the second movable frame 3b are synchronously tilted in one direction as a whole, that is, used to achieve the adjustment effect in Example 1.
