Description

Technical Field

[0001] The present invention relates to the technical field of surgical equipment, and more particularly to a spinal surgery bracket device. Background Art

[0002] Spinal diseases refer to the lesions of the bones, intervertebral discs, ligaments, and muscles of the spine, which then compress, traction, and stimulate the spinal cord, spinal nerves, blood vessels, and autonomic nerves, resulting in complex and diverse symptoms. The main symptoms include inability to stand upright, headache, dizziness, blurred vision, memory loss, neck and shoulder soreness, loss of appetite, nausea, vomiting, weakness in the lower limbs, and in severe cases, paralysis may occur.

[0003] The Chinese invention patent with the publication number CN110215292A discloses a bracket device for spinal surgery, which effectively solves the problems in the prior art that it is necessary to lift the patient to adjust the spinal curvature, the existing spinal bracket cannot adjust the length according to the patient's body type, has a single function, a simple structure, cannot support parts other than the abdomen, and it is easy to cause pressure sores to the patient due to too long operation time. Through the liftable support plate, the effect of quickly adjusting the spinal curvature of the patient during the operation is achieved, saving time and effort; through the movable and adjustable bed board, it can be used by patients of various body types and provides a comfortable spinal surgery bracket for the patient.

[0004] It can be seen that currently, the commonly used brackets for the spine are still of an arc structure, and the size and curvature of the arc are adjusted by driving the rise and fall of the arc plate by a motor. However, it can be known from the actual use process that although the arc-shaped bracket forms a support at the bottom of the patient, the arc position is generally at the lumbar vertebra and below the lumbar vertebra, and it cannot form a good working plane for thoracic and cervical spine surgeries, and for continuous surgeries such as scoliosis, the arc-shaped bracket cannot provide a good supporting effect; in addition, the existing bracket does not have a transfer function after the operation. Although the patient's posture can be changed to a horizontal prone position as the bracket contracts, the raised parts of various support structures do not allow the patient to move, and the transfer process is difficult.

Detailed implementation manners

[0032] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the drawings in the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. A spinal surgery bracket device related to the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0033] Refer to Figures 1-4, the present invention provides a spinal surgery bracket device, including a bedplate assembly 1. The bedplate assembly 1 includes a bedplate main body 101. First sliding grooves 102 are provided on the sides of the front and back of the bedplate main body 101. A baffle assembly 5 is installed between the first sliding grooves 102. On the other side of the back of the bedplate main body 101, a second sliding groove 106 is provided. A head support plate 6 is installed at the second sliding groove 106. A plurality of first positioning holes 107 are provided at the top of the second sliding groove 106, and a support bracket hole 108 is provided on the side of the second sliding groove 106. A middle groove 105 and a footrest groove 103 are provided at the top of the bedplate main body 101. Footrest secondary grooves 104 are provided on both sides of the footrest groove 103. A first support plate 2 and a second support plate 3 are installed at the middle groove 105 on the top of the bedplate main body 101. The sides of the first support plate 2 and the second support plate 3 are respectively connected to the head support plate 6 and the thigh support plate 14. Telescopic brackets 9 are installed on the fronts of the first support plate 2 and the second support plate 3. The second support plate 3 and the thigh support plate 14 are hingedly connected by a first connecting plate 15. The other side of the thigh support plate 14 is hinged with a leg sliding frame 4. A control square groove 109 is provided on the side of the bedplate main body 101, and a start-stop assembly 13 is installed inside the control square groove 109;

[0034] In this embodiment, it should be specifically noted that: a head assembly 7 and a tightening belt 8 are installed on the top of the head support plate 6. A driving motor 11 and a transmission assembly 12 are installed at the bottom of the bedplate main body 101. The transmission assembly 12 is composed of a transmission rod and a screw rod. The two ends of the transmission rod are respectively installed at the bottom of the screw rod and the first support plate 2. When the screw rod rotates, the transmission rod pushes the first support plate 2 to rise.

[0035] The main difference between this embodiment and the prior art is that in this embodiment, the driving of the motor is used to realize the rise and fall of the first support plate 2 and the second support plate 3, forming a horizontal platform during the patient's surgery, which is beneficial to achieving a better support effect on various parts of the patient's spine. At the same time, the extensibility of the first support plate 2 and the second support plate 3 is used to increase the adjustment of the support plane, so that the plane has a relatively accurate support ability for various types of personnel. Specifically, it lies in the first support plate 2, the second support plate, the baffle assembly 5, and the head assembly 7;

[0036] The above structure is the main structure of this embodiment, which solves the problem that the working horizontal plane during the patient's surgery cannot be adjusted in width according to the actual situation of the patient, and at the same time, the problem that the patient cannot perform convenient posture adjustment after the surgery. The telescopic bracket 9 is an existing structure, and the specific structure and elongation method of the telescopic bracket 9 are not specifically described in this embodiment.

[0037] Refer to Figure 5, the first support plate 2 includes a lower support plate body 201. One side of the lower support plate body 201 is fixedly connected with a cloth support 202. One end of the support cloth 10 is installed on the cloth support 202. A first connection groove 205 is formed on the front surface of the lower support plate body 201. The other end of the lower support plate body 201 is divided into upper and lower layers. A transmission hole 204 is formed in the upper layer, and a lower support rod 203 is fixedly connected to the lower layer. The lower support rod 203 is installed on the second support plate 3. The second support plate 3 includes an upper support body 301. A second connection groove 302 is formed on the right side of the upper support body 301. A first connecting plate 15 is hinged inside the second connection groove 302. A third connection groove 303 and a first rotation groove 304 are formed on the front surface of the upper support body 301. A rotating rod 305 is installed inside the first rotation groove 304. The rotating rod 305 is meshed and connected with an upper screw rod 306. The upper screw rod 306 is composed of a gear and a screw rod. The screw rod is installed inside the transmission hole 204, and the gear is meshed with the spiral groove on the rotating rod 305.

[0038] In this embodiment, it should be specifically noted that: when the patient is too tall or the surgical site is above the cervical vertebra or below the thoracic vertebra, it is necessary to expand the support surface of the first support plate 2 and the second support plate 3. At this time, rotate the rotating rod 305. Since the rotating rod 305 is provided with a thread groove and is meshed with the gear of the upper screw rod 306, when the rotating rod 305 rotates, the rotating rod 305 and the upper screw rod 306 form a worm mechanism. The rotating rod 305 drives the upper screw rod 306 to rotate inside the transmission hole 204, so that the first support plate 2 and the second support plate 3 move relatively to realize the elongation and expansion of the support surface.

[0039] Refer to Figure 6 , the baffle assembly 5 includes a moving frame 501. A rotation groove is formed on the top of the moving frame 501. A rotating baffle 502 is installed inside the rotation groove. A rubber block 503 is fixedly connected to the side surface of the rotation groove. One-way side plates 504 are fixedly connected to both sides of the moving frame 501. The one-way side plates 504 are installed at the bottom of the one-way side plates 504. When in use, rotate the rotating baffle 502 to the vertical position and push the baffle assembly 5 towards the patient's feet to block it. The one-way structure makes the above operation convenient.

[0040] In this embodiment, it should be specifically noted that after the operation, the rotating square plate 1302 is moved. At this time, the moving inclined block 1303 loses contact with the one-way inclined plate 1304, and the one-way inclined plate 1304 rises under the action of the reset spring 1305, so that the one-way side plate 504 can move bidirectionally at this time. The medical staff move the baffle assembly 5 to the farthest position and rotate the rotating baffle 502 to the horizontal position, take out the patient placed on the footrest groove 103, then untie the tightening belt 8 and start the drive motor 11. The first support plate 2 and the second support plate 3 start to descend under the drive of the drive assembly 12, and the rotating baffle 502 and the ankle joint bracket 16 move to the bottom of the leg sliding frame 4 to complete the storage.

[0041] Refer to Figure 7 And Figure 2 , the start-stop assembly 13 includes a first moving rod 1301 and a one-way inclined plate 1304. One end of the first moving rod 1301 is equipped with a rotating square plate 1302. A moving inclined block 1303 is fixedly connected to the first moving rod 1301. A reset spring 1305 is installed on the top of the one-way inclined plate 1304. The reset spring 1305 is in the same position as the moving inclined block 1303. When the rotating square plate 1302 moves, the moving inclined block 1303 and the one-way inclined plate 1304 will be disengaged, and the one-way inclined plate 1304 rises under the action of the reset spring 1305, so that the one-way side plate 504 can move bidirectionally.

[0042] In this embodiment, it should be specifically noted that when in the original state, the moving inclined block 1303 exerts a downward pressure on the one-way inclined plate 1304, so that the one-way teeth at the bottom of the one-way inclined plate 1304 are engaged with the one-way teeth on the one-way side plate 504, and the one-way side plate 504 can only move to the left.

[0043] Refer to Figure 8 And 10 , the head assembly 7 includes a head bracket 701. An oxygen connecting pipe 702 is fixedly connected to the bottom of the head bracket 701. A buffer ring 703 and a lower fixing ring 705 are installed at the bottom of the head bracket 701. The head bracket 701 is fixedly connected to the lower fixing ring 705 through a fixing rod. The buffer ring 703 is installed outside the fixing rod. The side of the buffer ring 703 is installed inside the buffer groove. A buffer assembly 707 is installed inside the buffer groove. When the fixing rod moves downward, the buffer assembly 707 buffers the up and down vibration of the fixing rod. First springs 706 are installed at the tops of the outer sides of the lower fixing ring 705 and the buffer ring 703.

[0044] The buffer assembly 707 is composed of an inclined rod and a spring. The inclined rod is fixedly connected to the buffer ring 703 through a pin. The whole of the head assembly 7 is installed on the head support plate 6 through a pin. After removing the pin, the head assembly 7 can be taken out from the head support plate 6. The length of the inclined rod is the same as the length of the buffer groove on the support plate body 601. After removing the head assembly 7, the inclined rod can be reversely rotated and placed inside the buffer groove.

[0045] In this embodiment, it should be specifically noted that: A buffer ring 703 is installed between the buffer ring 703 and the lower fixed ring 705. The buffer ring 703 is composed of a rotary knob and a connecting rod. When it is necessary to adjust the height of the head bracket 701, turn the rotary knob, and the height between the buffer ring 703 and the lower fixed ring 705 changes. The first spring 706 between the buffer ring 703 and the lower fixed ring 705 plays a supporting role, so that the maximum distance is maintained between the buffer ring 703 and the lower fixed ring 705.

[0046] Refer to Figure 8 And Figure 9 As shown in, the head support plate 6 includes a support plate body 601. Two hand support grooves 602 are opened on the upper surface of the support plate body 601. Tightening straps 8 are installed on both sides of the top of the hand support grooves 602. The two sides of the support plate body 601 are fixedly connected with a lower sliding block 603 and an upper sliding block 604. A through hole is opened at the top of the upper sliding block 604. The upper sliding block 604 is installed inside the second sliding groove 106. The lower sliding block 603 is installed inside the first sliding groove 102. When moving, the head support plate 6 is fixed by placing a pin inside the first positioning hole 107 into the through hole. A collecting rod 605 and a guiding rod 606 are installed at the bottom of the support plate body 601. The collecting rod 605 serves as the fixed axis of the support cloth 10, and a scroll spring and a cam are installed at both ends. The support cloth 10 passes through the bottom of the guiding rod 606 and is fixed on the cloth support 202. When the support cloth 10 is pulled, the scroll spring stores kinetic energy and keeps the support cloth 10 in a tensioned state.

[0047] In this embodiment, it should be specifically noted that: A disinfectant solution tank and a disinfectant solution release groove are opened inside the support plate body 601. A nozzle 607 is opened at the bottom of the support plate body 601. A pressing plate assembly 608 is installed on the side of the disinfectant solution release groove. The pressing plate assembly 608 is composed of a spring, a push rod and a pressing plate. When the cam drives the push rod to move, the pressing plate moves inside the disinfectant solution release groove to increase the internal pressure, and the disinfectant solution is released from the collecting rod 605 onto the support cloth 10.

[0048] The working principle of the present invention:

[0049] The main problems solved by this embodiment are as follows: using the transmission of the motor to realize the rise and fall of the first support plate 2 and the second support plate 3, forming a horizontal platform during the patient's operation, which is beneficial to achieving a better support effect on various parts of the patient's spine. At the same time, using the extensibility of the first support plate 2 and the second support plate 3 to increase the adjustment of the support plane, so that the plane has a more accurate support ability for various types of personnel, solving the problem that the working horizontal plane during the patient's operation cannot be adjusted in width according to the actual situation of the patient, and at the same time, the problem that the patient cannot perform convenient posture adjustment and transfer after the operation.

[0050] The specific steps are as follows:

[0051] During the patient's operation, let the patient lie prone above the device, start the drive motor 11, the drive motor 11 drives the drive assembly 12 to rotate, and drives the first support plate 2 and the second support plate 3 to rise through the drive rod. During the rise, since the telescopic brackets 9 are mirror-mounted on the first support plate 2 and the second support plate 3, the first support plate 2 and the second support plate 3 always remain horizontal during the rise, and the telescopic brackets 9 continuously extend to support the patient's chest. When reaching the operation height, adjust the support lengths of the first support plate 2 and the second support plate 3 according to the patient's height and the operation site;

[0052] When the patient's height is too high or the operation site is above the cervical vertebra or below the thoracic vertebra, it is necessary to expand the support surface of the first support plate 2 and the second support plate 3. At this time, rotate the rotating rod 305. Since the rotating rod 305 is provided with a threaded groove and is meshed with the gear of the upper screw rod 306, when the rotating rod 305 rotates, the rotating rod 305 and the upper screw rod 306 form a worm mechanism, and the rotating rod 305 drives the upper screw rod 306 to rotate inside the transmission hole 204, so that the first support plate 2 and the second support plate 3 move relative to each other to realize the elongation and expansion of the support surface;

[0053] During the rising process of the first support plate 2 and the second support plate 3, at the leg position, the thigh support plate 14 changes its position through the first connecting plate 15 driven by the second support plate 3. The top height is flush with the second support plate 3, and the bottom height is flush with the leg sliding bracket 4. The patient's thigh is placed in the upper surface groove of the thigh support plate 14, and the leg sliding bracket 4 supports the patient's calf. At this time, the medical staff places the patient's foot tip down inside the footrest groove 103, and the ankle joint bracket 16 moves to the patient's ankle to support it. Then rotate the rotating baffle 502 to the vertical position and push the baffle assembly 5 towards the patient's sole to block it. Since the two ends of the ankle joint bracket 16 are installed inside the footrest sub-groove 104 and can move left and right, to prevent the patient from sliding to both sides under anesthesia, at this time the rotating baffle 502 fixes the patient's foot position, and under the action of the one-way structure of the start-stop assembly 13, the user can more conveniently perform the blocking operation on the baffle assembly 5;

[0054] Meanwhile, at the head position, as the first support plate 2 and the second support plate 3 rise, since one end of the support cloth 10 is installed on the cloth bracket 202, the other end of the support cloth 10 drives the collection rod 605 to rotate. Since cams are installed at both ends of the collection rod 605, the movement of the support cloth 10 causes the cams to drive the push rod to reciprocate. In each rightward movement, the pressure on the disinfection liquid release groove by the pressing plate assembly 608 increases, and the disinfection liquid is released from the nozzle 607 onto the support cloth 10, so that the used part of the support cloth 10 always remains clean;

[0055] After the adjustment of the patient's legs, the medical staff move the head support plate 6, so that the upper sliding block 604 slides inside the second sliding groove 106, and re-fix the position of the pin in the first positioning hole 107 to achieve the adjustment of the horizontal position of the head. Then loosen the adjusting rod 704. As the length continuously increases, the first spring 706 between the buffer ring 703 and the lower fixing ring 705 pushes the buffer ring 703 to rise continuously, so that the height of the head bracket 701 continuously increases. When the head bracket 701 reaches the appropriate horizontal position of the patient's head, the height adjustment is completed. Oxygen is connected from the oxygen connecting pipe 702 to adjust the inhaled gas during the patient's operation. Then, the binding belt 8 is used to bind the patient's elbows to complete the fixation of the upper body position.

[0056] After the operation, first move the rotating square plate 1302. At this time, the moving inclined block 1303 loses contact with the one-way inclined plate 1304. The one-way inclined plate 1304 rises under the action of the return spring 1305, so that the one-way side plate 504 can move bidirectionally at this time. The medical staff move the baffle assembly 5 to the farthest position and rotate the rotating baffle 502 to the horizontal position, take out the patient placed on the footrest groove 103, and then untie the binding belt 8 and start the drive motor 11. The first support plate 2 and the second support plate 3 start to descend under the drive of the drive assembly 12. The rotating baffle 502 and the ankle joint bracket 16 move to the bottom of the leg sliding frame 4 to complete the storage. The patient's toes are located at the gap between the leg sliding frame 4 and the baffle assembly 5 after descending. On the other hand, since the buffer assembly 707 and the first spring 706 buffer the patient's head, during the descending process, the head bracket 701 descends slightly to support the patient's head. In the second half of the descent, the medical staff remove the pin at the inclined rod of the buffer assembly 707, remove all the components of the head assembly 7 upward, and place the inclined rod in the slot after rotating it in the reverse direction. At this time, the head assembly 7 is removed, and then the position of the head assembly 7 is replaced with a headrest to complete the postoperative support for the patient's head.

[0057] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
