Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to an operating bed for hepatobiliary and pancreatic surgery with limb fixation. Background Art

[0002] In hepatobiliary and pancreatic surgery, it is inevitable to perform surgeries on patients. When patients undergo surgeries, they need to lie on the operating bed. For patients with limited mobility, moving them to the operating bed generally involves medical staff and the patient's family members transferring the patient from the hospital bed in the ward to a transfer bed, and then moving the transfer bed into the operating room for a second transfer, so that it is convenient for doctors to perform surgeries on the patient on the operating bed. After the patient's surgery is completed, the medical staff will transfer the patient to the transfer ward again and take care of the patient in the hospital bed in the ward. The patient's repeated bed transfer not only requires the assistance of multiple people, but also is not good for the patient's injury. In addition, the common existing operating beds on the market are inconvenient for users to adjust the angle of the backrest during operation, resulting in inconvenience for users to operate the entire operating bed. At the same time, the common operating beds do not have a height adjustment function. In hepatobiliary and pancreatic surgery, the patient's body position also needs to be adjusted to facilitate surgical operations, including lying flat, lying on the side, etc., and the patient's arms also need to be fixed during the operation. The existing operating beds do not have relevant structures. Therefore, commonly, an external binding belt is used to wrap around the operating bed for one week, and then the patient is bound and protected. The use is complicated, and the binding belt is not fixed to the operating bed and is prone to sliding off, which will affect the working and use effects of the operating bed. Summary of the Invention

[0003] The purpose of the present invention is to provide an operating bed with a detachable and adjustable limb placement frame. The operating bed of the present invention can be used as a general hospital bed. Based on the mechanical control of lifting by setting a crank handle and the multi-angle swing adjustment of the bed board, it can not only meet the use requirements in hepatobiliary and other surgeries, but also directly move the operating bed to the ward after the operation, without the need for the patient to transfer beds, etc., which is convenient for use.

[0004] The technical solution adopted by the present invention is as follows: A hospital bed for assisting hepatobiliary and pancreatic surgery with limb fixation, including a bed frame. The main body of the bed frame includes a frame body and side beams with chutes and mounting grooves. The mounting grooves and chutes on the side beams are arranged opposite to each other. The chute forms a moving travel track for the auxiliary component in the length direction of the side beam, and the mounting groove facilitates the installation and disassembly of the lateral pushing of the auxiliary component into the chute, enabling quick assembly and disassembly. The adjustable bed board is arranged on the upper side of the frame body of the bed frame. Here, the connection between the adjustable bed board and the frame body is hinged or partially fixed according to its swinging and moving states. The adjustable bed board is provided with at least two groups of adjusting bottom plates along the length direction. Each group of the adjusting bottom plates is provided with two relatively independent top plates that can be flipped along the width direction. Here, the adjusting bottom plates are used to swing relative to the frame body to form support for the upper or lower limbs of the patient, and they carry the top plates when swinging. When the top plates do not flip and swing, the adjusting bottom plates and the top plates remain parallel and stacked. The top plates are mainly used to form a slope relative to the other side of the bed board to facilitate the back support for the side lying position required by some patients.

[0035] As a further setting of the above solution, a detachable medicine bottle hanger 5 is further provided on the bed frame 1, and a plurality of pulley members 8 are further provided on the frame body 11 at the bottom of the bed frame 1.

[0036] Reference Figure 1 As shown in the bed frame 1 of the present invention, an adjustable bed board 2 is provided, and the bed frame 1 is constructed into a frame body 11 by metal for the installation of the adjustable bed board 2. A side beam 12 is provided on the side of the frame body 11. The adjustable bed board 2 is installed between the two side beams 12. A lifting bracket 31 is provided on the frame body 11, and the top of the lifting bracket 31 is hinged to the adjustable bed board 2. As Figure 2 And Figure 4 As shown in the present invention, by rotating the lifting crank lever 300, based on the setting that the lifting crank lever 300 is axially fixed relative to the frame body 11 and the threaded fit of the external thread structure 308 and the threaded sleeve 309, the lifting crank lever 300 only rotates circumferentially. Thus, the sliding beam 302 fixed to the threaded sleeve 309 slides along the sliding grooves 304 at both ends. As Figure 2 As shown in the present invention, when the sliding beam 302 moves along the sliding groove 304, the first strut 301 hinged in the middle of the cross swings, forming an effect of pushing the upper bed board up and down. The operating bed of the present invention adjusts the height of the supporting bed body through a mechanical structure drive, and is adjusted by rotating the lifting crank lever 300, which is convenient for adjusting based on the change of the height requirement during the operation process.

[0037] Further, as Figure 1 And Figure 9 As shown in the structure of the limb fixing assembly 4 installed on the side beam 12 of the present invention, there are two solutions. Figure 9 Generally used for fixing and supporting the limb, it is mostly used during the operation and for children to prevent sudden movements of such patients, which may affect the operation of medical staff or affect the instrument (needle). And Figure 1The bundling setting in it is mainly aimed at some special patients, especially those who have a fever or infection after surgery. Some patients may have problems such as delirium and hyperactivity. Therefore, the present invention designs a lower limb fixing band 44 that can bundle both feet at the same time and an upper limb fixing band 45 that can optionally bundle each of the left and right hands or a single hand. The upper limb fixing band 45 of this embodiment is provided with a palm sleeve 444 to protect the palm and fingers of the hand and prevent the patient from scratching randomly. Through the limb fixing assembly 4 of this embodiment, the side beam 12 is used as a fixing point to support and fix the limb, meeting the nursing needs of patients during or after surgery.

[0038] Reference Figure 3 As shown, the adjustment bracket 3 of the present invention of the present invention is further provided with a first swing bracket 32 and a second swing bracket 33. As Figure 3 shown, by using a mechanical structure similar to the above principle, the first swing bracket 32 of this embodiment rotates the first crank handle 321. The first crank handle 321 is in threaded cooperation with the internal threaded hole 322 on the frame body 11 to realize the axial expansion and contraction of the first crank handle 321, thereby pushing the swing rod member 323 hinged to its end to swing. The other end of the swing rod member 323 is hinged to the adjustment bottom plate 21. Based on the axial expansion and contraction of the first crank handle 321, the adjustment bottom plate 21 is pushed to swing up with a single-side hinge, so as to form an angle adjustment convenient for the upper limb of the patient relative to the tilt angle of the head of the bed.

[0039] Furthermore, the second swing bracket 33 of this embodiment drives the swing arm one 333 to swing by rotating the second crank handle 331. When the swing arm one 333 swings and pushes the third plate body 203 to swing, the swing arm two 335 connected to the waist-shaped sliding hole 334 on the swing arm one 333 pushes the fourth plate body 204 to swing, so that the third plate body 203 and the fourth plate body 204 form an angle adjustment relative to the lower limb of the patient, meeting the requirements of the surgical process.

[0040] Reference Figure 4 and Figure 5As shown, the adjustable bed board 2 of the present invention is structurally divided into two layers. The lower layer is the adjustment bottom board 21 which is relatively connected to the frame body 11, and can be swing-adjusted through adjustment brackets 3 such as the lifting bracket 31. The upper layer is the top board 22. The top board 22 is hinged to the inner side of the adjustment bottom board 21. A sliding groove 343 is provided on the back of the bottom. A flipping bracket 34 is designed on the frame body 11. The sliding block 342 hinged to the end of the rotating crank 341 provided on the flipping bracket 34 is located in the sliding groove 343 and slides along the sliding groove 343. The rotating crank 341 of the flipping bracket 34 is in threaded cooperation with the adjustment bottom board 21. When rotating, it extends upward relative to the adjustment bottom board 21. Based on the sliding of the sliding block 342 along the sliding groove 343, the top board 22 is pushed to swing relative to the adjustment bottom board 21, and its swinging direction is to tilt and turn up from the outside to the inside, which can provide support for the patient's back during a lateral lying operation and is convenient for use.

[0041] Furthermore, through the arrangement of the installation groove 14 and the sliding groove 13 on the side beam 12 of the bed frame 1 of the present invention, during use, the movable block 422 of the C-shaped sliding frame 42 of the limb fixing assembly 4 is aligned with the side of the installation groove 14 and pressed in, and then the movable block 422 slides along the sliding groove 13, so as to realize the adjustment of the position of the fixing bracket 41 according to the limb position of the patient. Further, the fixing bracket 41 of the present invention further includes a placement rack 43. The placement rack 43 is used for stably placing the limb, and the placement rack 43 of this embodiment is connected to the C-shaped sliding frame 42 through a swing shaft 431. During use, it can swing back and forth by 30 degrees through the swing shaft 431 to adapt to the limb placement. In addition, the placement rack 43 is also provided with a finger buckle 433 and an insertion buckle binding band 434 design. There are at least two insertion buckle binding bands 434, and side plate bodies 435 are arranged on both sides of the limb. Its function is that during use, the upper belt body 437 forms a restriction on the limb, and the side plate bodies 435 on both sides cooperate with the belt body 437 to form a loose binding on the side of the limb. This setting takes into account the situation of limb intravenous injection during the operation to avoid the binding band from pressing on the blood vessels.

[0042] The surgical hand-assisted hospital bed of the present invention adopts a mechanical structure and can quickly adjust the bed body through the operating handle crank to meet the patient's body position requirements during the operation. And its operation is very simple, and it can be adjusted at any time when needed, quickly meeting the use requirements, which is convenient for surgical assistance. And the limb fixing bracket of the present invention adopts a simple structure for side-mounted and easy-disassembly design, which can be quickly and conveniently disassembled and assembled, and can be installed and used when needed. And the limb fixing assembly can be adjusted relative to the bed frame according to needs, meeting the fixing requirements of different patients' limb lengths, positions and body postures.

[0043] Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the present invention's technical solution and its equivalent technologies, the present invention also intends to encompass these modifications and variations.
