[0002] The thyroid gland is a very important gland in vertebrates and is an endocrine organ. In mammals, it is located below the thyroid cartilage in the neck and on both sides of the trachea. The human thyroid gland is shaped like a butterfly, like a shield, hence the name. At present, surgery is the preferred treatment for thyroid diseases. The thyroid gland is located in the neck. The treatment of thyroid nodules usually involves surgery in the neck, using a scalpel to remove part or all of the patient's thyroid gland in the neck. During the operation, the patient's position should be in a head-up position to fully expose the thyroid gland. In order to facilitate the exposure of the surgical field of view, an air pressure bag or a water bag is generally used to support the neck so that the patient's neck is propped up. Because the height that needs to be propped up varies slightly for patients of different body sizes, the propped-up height will affect the surgical field of view after the operation, and after the operation, the doctor can no longer adjust the support height of the air pressure belt or water bag, so it can only be estimated with the help of the doctor's personal experience, and it is impossible to accurately determine whether the propped-up height is appropriate.

[0034] The invention provides an operating table for assisting thyroid surgery.

[0035] like Figures 1 to 5 The operating table for assisting thyroid surgery shown in the figure comprises a bed body 1, a controller, a camera 14, a first lifter 24 and a support frame 2. The bed body 1 is provided with a mounting through hole 11 in the vertical direction, and the support frame 2 is arranged in the mounting through hole 11; a lying space 12 is formed on the top side of the bed body 1, and the lying space 12 is used for patients to lie down; a first lifter 24 is arranged on the side of the bed body 1 away from the lying space 12, and the output end of the first lifter 24 is connected to the support frame 2, and the support frame 2 is located outside the lying space 12, and the first lifter 24 is used to The support frame 2 is vertically driven to extend along the mounting through hole 11 into the lying space 12, so that the support frame 2 supports the neck of the patient located in the lying space 12; a mounting frame 13 is also provided on the side of the bed body 1 away from the first lifter 24, and a camera 14 is provided on the mounting frame 13. The controller is electrically connected to the camera 14 and the first lifter 24 respectively, and the camera 14 is used to take an image of the patient's neck and send it to the controller; the controller is used to control the first lifter 24 according to the neck image, so that the support frame 2 props up the patient's neck to a corresponding height.

[0036] The camera 14 is used to obtain the surgical image of the surgical site of the patient's neck, and then the lifting height of the first lifter 24 is controlled according to the exposure of the thyroid gland in the surgical image, so that the patient's neck is fully supported by the support frame 2 to ensure that the thyroid gland is fully exposed, thereby ensuring the smooth progress of the operation.

[0037] Specifically, the camera 14 is also used to obtain the size data of the patient's neck and send it to the controller. The controller measures the gap height between the patient's back neck and the support frame according to the size data of the neck, and controls the first lifter 24 to raise the height of the support frame 2 according to the gap height. The larger the gap height, the lower the support frame 2 is raised, so as to avoid excessive support, which causes the muscle tissue of the patient's back neck to over-compress the cervical vertebrae, and avoids postoperative complications caused by excessive compression of the cervical vertebrae.

[0038] Specifically, the controller is also used to determine the lesion location based on the surgical image, and to determine whether the edge position of the lesion location contacts other human tissues at the surgical site. When the edge position contacts other human tissues, the controller controls the support frame 2 to rise to increase the exposed area of ​​the lesion location; when the edge position does not contact other human tissues, the support frame 2 maintains the current support height.

[0039] Specifically, the mounting frame 13 is provided with a display 15, and the controller is electrically connected to the display 15. The controller is used to obtain the patient's image picture from the hospital system so that the display 15 displays the image picture. This makes it convenient for doctors to assist in the operation by comparing the image picture. The camera 14 is also used to obtain the surgical image of the patient's incision during the operation and send it to the controller, and the controller is also used to display the surgical image through the display 15. This makes it convenient for doctors to compare the image picture with the surgical image to determine whether there is a hidden lesion, effectively improve the success rate of the operation, and also leave the surgical image to facilitate the record of the operation process, which can be used as medical evidence and surgical guidance. The camera 14 obtains the surgical image during the operation interval, which can avoid affecting the normal operation.

[0040] A lesion sample image is input into the controller, and the controller is used to obtain a surgical image and identify the lesion in the surgical image based on the lesion sample image, and mark the identified lesion area on the image displayed on the monitor; the controller is also used to compare the image and the surgical image to find the difference, and compare the difference with the lesion sample image to determine whether the difference is a lesion. If so, mark the difference on the image displayed on the monitor.

[0041] Specifically, the controller also controls the first lifter 24 according to the surgical image, so that when the exposed area of ​​the thyroid gland is smaller than the preset area, the first lifter 24 is controlled to drive the support frame 2 to rise, thereby increasing the exposed range of the thyroid gland.

[0042] The support frame 2 includes a connecting plate 21 and two clamping plates 22. The connecting plate 21 is arranged horizontally, and the output end of the first lifter 24 is connected to one side of the connecting plate 21. The two clamping plates 22 are arranged at intervals on the side of the connecting plate 21 away from the first lifter 24. An accommodating space 23 is formed between the two clamping plates 22. The two connecting plates 21 are used to abut against the patient's neck so that the patient's neck is located between the two clamping plates 22. The two clamping plates 22 clamp the patient's neck, which can prevent the neck from moving accidentally during the operation and ensure the safety of the operation.

[0043] The two clamping plates 22 are hinged by hinge shafts and connecting plates 21 respectively, and the two hinge shafts are arranged in parallel and spaced apart; the support frame 2 also includes two first telescoping devices 25, one of which is located on the side of one of the clamping plates 22 away from the accommodating space 23, and the other first telescoping device 25 is located on the side of the other clamping plate 22 away from the accommodating space 23; the output end of one of the first telescoping devices 25 is hinged to an adjacent clamping plate 22, and the output end of the other first telescoping device 25 is hinged to an adjacent clamping plate 22; the two first telescoping devices 25 are used to drive the two clamping plates 22 to move closer or farther away so that the two clamping plates 22 fit the patient's neck.

[0044] Specifically, the controller controls the two first retractors 25 respectively according to the neck image, so that the two clamping plates 22 are closely attached to the patient's neck.

[0045] A flexible layer (not shown in the figure) is arranged in the accommodation space 23, and the flexible layer is respectively connected to the side of the connecting plate 21 facing the accommodation space 23 and the side of the two clamping plates 22 facing the accommodation space 23. The flexible layer is used to abut against the patient's neck to lower the support frame, so as to prevent the support frame from rigidly contacting the patient and reduce damage to the patient's neck.

[0046] An adjustment mechanism 3 is also provided on one side of the bed body 1 forming the lying space 12. The adjustment mechanism 3 is located on the side of the support frame 2 away from the lying space 12. The controller is electrically connected to the adjustment mechanism 3. The controller is used to drive the patient's head to rotate and drive the cervical vertebra to rotate to expand the exposure range of the thyroid gland after the support frame 2 lifts the patient's neck to a suitable height and performs surgery. The adjustment mechanism 3 rotates the cervical vertebra by rotating the human head, thereby changing the position of the thyroid gland. At the same time, it cooperates with the two clamping plates 22 so that the skin layer outside the neck does not rotate, thereby increasing the exposure range of the thyroid gland without causing the expansion of the incision, thereby reducing the difficulty of surgery and the difficulty of recovery after surgery.

[0047] The adjustment mechanism 3 includes a mounting seat 31, a motor 32, a connecting frame 33, a second retractor 34 and a head cover 4. The second retractor 34 is arranged on the side of the support frame 2 away from the lying space 12, and the head cover 4 is located between the second retractor 34 and the support frame 2. A fixed space is formed on the side of the head cover 4 facing the support frame 2, and the fixed space is used to accommodate the patient's head; the output end of the second retractor 34 is connected to the mounting seat 31, and a motor 32 is arranged on the side of the mounting seat 31 away from the second retractor 34; the output end of the motor 32 is connected to the connecting frame 33, and the end of the connecting frame 33 away from the motor 32 is connected to the head cover 4, and the motor 32 is used to drive the head cover 4 to rotate through the connecting frame 33; the controller is electrically connected to the second retractor 34 and the mounting seat 31 respectively, and the controller is used to control the second retractor 34 to drive the head cover 4 to move toward the direction of the support frame 2, so as to accommodate the patient's head in the fixed space, so that the motor 32 drives the patient's head to rotate through the head cover 4 and drives the cervical spine to rotate, thereby increasing the exposure range of the thyroid gland. The human body lies in the bed 1, and the second retractor 34 drives the headgear 4 to approach the patient's head until the patient's head enters the fixed space, and then the motor 32 drives the headgear 4 to rotate, thereby controlling the head to drive the cervical spine to rotate and increase the exposure range of the thyroid gland.

[0048] Specifically, two limit plates 43 are arranged at the outer edge of the head cover 4, and two third lifters 16 are arranged at the bottom side of the bed body 1. The two third lifters 16 are symmetrically arranged along the telescopic path of the second telescoping device 34. Top plates 17 are arranged at the output ends of the two third lifters 16, one of which is used to abut against one of the limit plates 43; the other top plate 17 is used to abut against the other limit plate 43; the controller is electrically connected to the two third lifters 16, and the controller is used to control the lifting and lowering of each top plate 17, so that each top plate 17 limits the rotation distance of the adjacent limit plate 43. The purpose of limiting the rotation angle of the head cover 4 is achieved by limiting the rotation distance of the limit plate 43 by the top plate 17, so as to avoid accidents of the motor 32 and avoid the head cover 4 from twisting the patient's neck due to excessive rotation angle. The two top plates 17 play the role of insurance.

[0049] Specifically, the motor 32 is a stepping reduction motor 32 .

[0050] The bed body 1 is provided with a rectangular through hole 18, and the rectangular through hole 18 extends along the telescopic direction of the second telescopic member 34; the adjustment mechanism 3 also includes a second lifter 35 and a fixing frame 36, the second lifter 35 is located at the bottom side of the bed body 1, and the second lifter 35 is arranged near the end of the rectangular through hole 18 away from the support frame 2, the output end of the second lifter 35 is connected to the second telescopic member 34 through the fixing frame 36, and the controller is electrically connected to the second lifter 35, and the controller is used to adjust the horizontal height of the headgear 4 through the second lifter 35, so that the height of the patient's head is reduced to increase the exposure range of the thyroid gland. Through the cooperation of the second lifter 35 and the first lifter 24, the exposure range of the thyroid gland can be further increased.

[0051] Specifically, the first lifter 24, the second lifter 35 and the third lifter 16 are all fixed to the bottom side of the bed 1 through a suspension frame.

[0052] The headgear 4 includes a base cover 41 and a headband 42. The base cover 41 is horizontally arranged, and the headband 42 is located on the top side of the base cover 41. The base cover 41 is used to support the patient's head so that the headband 42 is sleeved on the patient's head. The headband 42 is provided with two clamping structures 5, and the two clamping structures 5 are symmetrically arranged. One of the clamping structures 5 is used to clamp one side of the patient's head so that the other clamping structure 5 can clamp the other side of the patient's head to fix the patient's head in the headband 42.

[0053] Specifically, the headband 42 and the bottom cover 41 are hinged by two hinged short shafts, and the headband 42 swings along the telescopic direction of the second telescopic 34 through each hinged short shaft. The lifting of the cervical spine and the lowering of the head will inevitably lead to slight changes in the positions of the head and the headband 42, and the setting of the hinged short shaft can be adjusted in accordance with these slight changes, so as to avoid severe friction between the compression structure 5 and the patient's head when the headgear 4 is lowered.

[0054] The headband 42 has two threaded through holes 44, which are coaxially arranged and symmetrically arranged. The clamping structure 5 includes a pressing plate 51, a screw 52 and a handle 53 connected in sequence, wherein one screw 52 is threadedly connected to one of the threaded through holes 44, and the other screw 52 is threadedly connected to the other threaded through hole 44. The two pressing plates 51 are arranged in parallel and spaced apart in the headband 42, and are used to clamp the patient's head. The doctor drives the corresponding pressing plate 51 to be close to the patient's head by rotating the two handles 53 located on the outside of the headband 42.

[0055] Specifically, a silicone layer is provided on the side of the pressing plate 51 facing the patient's head.

[0056] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
