Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an auxiliary retractor operating table. Background Technology

[0002] During surgery, the surgeon typically requires an assistant to use surgical retractors to pull on the wound site, increasing the exposed area and facilitating internal surgical procedures. Using surgical retractors does not require the assistant to possess specialized surgical skills; it can be performed under the surgeon's guidance. The angle of traction with the retractors is determined by the surgeon.

[0003] However, when the assistant uses the surgical retractor for traction, their physical strength declines significantly as the surgery time increases, making it impossible to maintain the strength and angle of holding the surgical retractor for an extended period, which may affect the surgeon's work. Utility Model Content

[0004] The purpose of this application is to provide an auxiliary retractor operating table that uses an auxiliary arm assembly to replace an assistant in performing traction operations with surgical retractors. This allows for the maintenance of traction force and angle for extended periods when using surgical retractors, thereby reducing the workload of the assistant and effectively improving the surgical efficiency of the surgeon.

The fourth rotating shaft passes through the fifth swing flange end, and the axis of the fourth rotating shaft is perpendicular to the extension direction of the second shaft hole. The third swing arm also includes a sixth electromagnetic chuck, two sixth swing flange ends, and two fourth bearing seats. The two sixth swing flange ends are respectively located at one end of the fifth connecting rod, and the two sixth swing flange ends are spaced apart by a predetermined distance along the extension direction of the fourth rotating shaft to form a third swing space between them. The two sixth swing flange ends are symmetrically provided with the same type of bearing as the first... The four rotating shafts extend in the same direction with a third shaft hole. Two fourth bearing seats are respectively installed on the side of the two sixth swing flange ends away from the third swing space, corresponding to the two third shaft holes. The two ends of the fourth rotating shaft are rotatably connected to the two fourth bearing seats. A sixth suction cup mounting groove is opened on each of the sixth swing flange ends.

[0013] Furthermore, the fifth link also includes a control button, which is electrically connected to an external power source to control the on / off state of the external power source; the control button is electrically connected to the first electromagnetic chuck, the second electromagnetic chuck, the third electromagnetic chuck, the fourth electromagnetic chuck, the fifth electromagnetic chuck, and the sixth electromagnetic chuck.

[0014] Analysis reveals that this utility model discloses an auxiliary retractor surgical table. When performing surgery using this table, the surgeon or assistant can adjust the angle and height of each joint in the entire auxiliary arm assembly by holding the third swing arm. This allows the surgical retractor connected to the end of the third swing arm to traction the wound at the angle required by the surgeon. After the surgeon or assistant has adjusted the posture of the entire auxiliary arm assembly, they can simultaneously energize the electromagnetic suction cups at each joint using the control button on the third swing arm. At this time, the electromagnetic suction cups at each joint can electromagnetically attract and fix the movable joints in the auxiliary arm assembly, thus maintaining the entire auxiliary arm assembly at the angle required by the surgeon for wound traction. Using the auxiliary arm assembly to replace the assistant for surgical retractor traction prevents changes in traction angle and force due to the assistant's physical exhaustion, effectively reducing the assistant's workload and simultaneously improving the surgeon's surgical efficiency.

Example

[0020] like Figures 1 to 12As shown, according to an embodiment of this application, an auxiliary retractor surgical bed is provided, which includes a bed body 1 and two auxiliary arm assemblies 2. The bed body 1 includes a body placement area 102 and head placement areas 101 at both ends of the body placement area 102, so that the patient to be operated on can lie on the bed body 1 in two directions according to the position of the operation. A mounting platform 103 is provided on one side of the tongue placement area. The mounting platform 103 has a mounting surface 103a parallel to the horizontal plane, and two auxiliary arm assemblies 2 are mounted on the mounting surface 103a by threaded connectors. Each auxiliary arm assembly 2 includes a base 201, a rotating arm 202, a first sliding arm 203, a first swing arm 204, a second swing arm 206, a third swing arm 207, and a plurality of electromagnetic suction cups 4. The end of the third swing arm 207 is detachably connected to a surgical retractor 3. Multiple electromagnetic chucks 4 include a first electromagnetic chuck 4a, a second electromagnetic chuck 4b, a third electromagnetic chuck 4c, a fourth electromagnetic chuck 4d, a fifth electromagnetic chuck 4e, and a sixth electromagnetic chuck 4f. Each electromagnetic chuck 4 includes a disc-shaped chuck metal body 401. A coaxial annular groove 401b is formed inside the chuck metal body 401. An annular iron core 402 wound with a copper coil 403 is disposed inside the annular groove 401b. One side of the annular iron core 402 has a connection with the copper coil. The power cord 404 is electrically connected to the coil 403. The annular iron core 402 has a magnetic surface 401a on the side facing away from the copper coil 403. When each electromagnetic chuck 4 is electrically connected to an external power source through the power cord 404 and is in a powered state, the magnetic surface 401a of each electromagnetic chuck 4 is magnetic; when each electromagnetic chuck 4 is electrically connected to an external power source through the power cord 404 and is in a de-powered state, the magnetic surface 401a of each electromagnetic chuck 4 is not magnetic. The rotating arm 202, the first sliding arm 203, the first swing arm 204, the second swing arm 206, and the third swing arm 207 are all made of magnetic metal or nickel-plated material so that they can be magnetically attracted by their respective electromagnetic chucks 4.

[0021] Specifically, the base 201 includes a mounting flange seat 201a, a support flange platform 201b, a first bearing seat 201e, and multiple first spherical balls 201h. The mounting flange seat 201a is located at the bottom of the base 201, and the base 201 is mounted to the mounting surface 103a of the bed 1 via a threaded connector. The support flange platform 201b is located at the top of the mounting flange seat 201a. A longitudinally extending mounting cavity 201c is formed between the support flange platform 201b and the mounting flange seat 201a. The first bearing seat 201e is installed in the mounting cavity 201c, and the shaft hole of the first bearing seat 201e extends longitudinally. A first suction cup mounting groove 201d is also formed longitudinally on the support flange platform 201b, and a first electromagnetic chuck 4a is embeddedly connected to the support flange platform 201b through the first suction cup mounting groove 201d. Multiple first ball grooves 201g are evenly provided on the support flange 201b around the shaft hole of the first bearing seat 201e, and each first ball groove 201g is provided with a first spherical ball 201h that can roll.

[0022] The rotating arm 202 includes a first rotating shaft 202a and a rotating disk 202c. The first rotating shaft 202a extends longitudinally, and its bottom end is rotatably connected to the shaft hole of the first bearing seat 201e. A first annular groove 202b is formed at the bottom end of the first rotating shaft 202a corresponding to the bottom side of the first bearing seat 201e. A first shaft buckle 201f is engaged in the first annular groove 202b. The rotating disk 202c is coaxially connected to the circumference of the first rotating shaft 202a corresponding to the top side of the first bearing seat 201e. The relative displacement of the first rotating shaft 202a and the first bearing seat 201e in the longitudinal direction can be restricted by the first shaft buckle 201f and the rotating disk 202c. The bottom of the rotating disk 202c abuts against a plurality of first spherical balls 201h, and the bottom of the rotating disk 202c is in contact with the magnetic suction surface 401a of the first electromagnetic chuck 4a. When the first electromagnetic chuck 4a is de-energized, the first rotating shaft 202a can drive the rotating disk 202c to rotate relative to the supporting flange 201b around its axis; when the first electromagnetic chuck 4a is energized, the magnetic surface 401a of the first electromagnetic chuck 4a attracts the bottom surface of the rotating disk 202c, so that there is no relative rotation between the first rotating shaft 202a and the base 201.

[0023] The first sliding arm 203 includes a second electromagnetic chuck 4b, a first connecting rod 203a, and a first sliding sleeve 203b disposed at one end of the first connecting rod 203a. Two symmetrical first guide surfaces 202d extending longitudinally toward the rotating disk 202c are provided on the top side of the first rotating shaft 202a. Each first guide surface 202d has a first limiting block 202e and a second limiting block 202f at both ends of its extension direction. The first sliding sleeve 203b has a first guide hole 203c longitudinally that matches the two first guide surfaces 202d. The first sliding sleeve 203b is fitted onto the periphery of the first rotating shaft 202a through the first guide hole 203c and the two first guide surfaces 202d. The first sliding sleeve 203b has a second suction cup mounting groove 203d perpendicular to any of the first guide surfaces 202d on one side. The second electromagnetic chuck 4b is embedded in the first sliding sleeve 203b through the second suction cup mounting groove 203d, and the magnetic suction surface 401a of the second electromagnetic chuck 4b is in contact with its corresponding first guide surface 202d. When the second electromagnetic chuck 4b is de-energized, the first sliding sleeve 203b can drive the first connecting rod 203a to slide back and forth between the first limiting block 202e and the second limiting block 202f along the extension direction of the first guide surface 202d. When the second electromagnetic chuck 4b is energized, the magnetic suction surface 401a of the second electromagnetic chuck 4b attracts its corresponding first guide surface 202d, so that there is no relative sliding between the first sliding sleeve 203b and the first rotating shaft 202a.

[0024] The first sliding arm 203 further includes a third electromagnetic chuck 4c, two second bearing seats 203h, two first swing flange ends 203e disposed at the end of the second connecting rod 204a opposite to the first sliding sleeve 203b, and a plurality of second spherical balls 203k. The two first swing flange ends 203e are spaced apart by a predetermined distance in the horizontal direction so that there is a first swing space 203f between the two first swing flange ends 203e, and a first shaft hole 203g is opened on the two first swing flange ends 203e in the horizontal direction to pass through them. A second bearing seat 203h is installed on the side of each first swing flange end 203e opposite to the first swing space 203f and corresponding to the first shaft hole 203g thereon. The first swing arm 204 includes a second connecting rod 204a, a second swing flange end 204b disposed at one end of the second connecting rod 204a, and a second rotating shaft 204c. The second rotating shaft 204c passes through the second swing flange end 204b and abuts against both sides of the second swing flange end 204b via two second shaft clips 204d. The second swing flange end 204b is built into the first swing space 203f and is rotatably connected to two second bearing seats 203h via both ends of the second rotating shaft 204c. Two second annular grooves 204e are formed at both ends of the second shaft hole 206d corresponding to the two second bearing seats 203h. A third shaft clip 204f is engaged in each second annular groove 204e to prevent relative displacement between the second rotating shaft 204c and the two second bearing seats 203h. Multiple second ball grooves 203j are formed on the side of each first swing flange near the first swing space 203f. A second spherical ball 203k is provided in each second ball groove 203j, and each second spherical ball 203k abuts against the second swing flange end 204b. A third suction cup mounting groove 203i is provided on the side of any first swing flange end 203e near the first swing space 203f. The third electromagnetic chuck 4c is embedded in its corresponding first swing flange end 203e through the third suction cup mounting groove 203i, and its magnetic suction surface 401a is in contact with the second swing flange end 204b. When the third electromagnetic chuck 4c is de-energized, the second swing flange end 204b can drive the second connecting rod 204a to swing back and forth around the second rotating shaft 204c relative to the two first swing flange ends 203e. When the third electromagnetic chuck 4c is energized, its magnetic suction surface 401a attracts the second swing flange end 204b, so that there is no relative swing between the second swing flange end 204b and the two first swing flange ends 203e.

[0025] The second sliding arm 205 includes a fourth electromagnetic chuck 4d, a third connecting rod 205a, and a second sliding sleeve 205b, with the second sliding sleeve 205b disposed at one end of the second connecting rod 204a. The end of the second connecting rod 204a facing away from the second swing flange end 204b, along the extending direction of the second connecting rod 204a, has two symmetrically formed second guide surfaces 204g extending towards the second swing flange end 204b. Each second guide surface 204g has a third limiting block 204h and a fourth limiting block 204i at its two ends in the extending direction. The second sliding sleeve 205b has a second guide hole 205c extending in the same direction as the second guide surfaces 204g and matching the two second guide surfaces 204g. The second sliding sleeve 205b is fitted onto the periphery of the second connecting rod 204a through the second guide hole 205c. The second sliding sleeve 205b has a fourth suction cup mounting groove 205d on its side, corresponding to any second guide surface 204g. The fourth electromagnetic chuck 4d is embedded in the fourth suction cup mounting groove 205d, and its magnetic suction surface 401a is in contact with its corresponding second guide surface 204g. When the fourth electromagnetic chuck 4d is de-energized, the second sliding sleeve 205b can drive the third connecting rod 205a to slide back and forth between the third limiting block 204h and the fourth limiting block 204i along the extension direction of the second guide surface 204g. When the fourth electromagnetic chuck 4d is energized, its magnetic suction surface 401a attracts the corresponding second guide surface 204g, so that there is no relative sliding between the second sliding sleeve 205b and the second connecting rod 204a.

[0026] The second sliding arm 205 also includes a third swing flange end 205e and a third rotating shaft 205f.

When the sixth electromagnetic chuck 4f is de-energized, the two sixth swing flange ends 207b can drive the fifth connecting rod 207a to swing back and forth around the fourth rotating shaft 206j relative to the fifth swing flange end 206i. When the sixth electromagnetic chuck 4f is energized, its magnetic suction surface 401a attracts the fifth swing flange end 206i, so that there is no relative swing between the two sixth swing flange ends 207b and the fifth swing flange end 206i.

[0028] The third swing arm 207 also includes a hook mounting bracket 207i, which is detachably connected to the end of the fifth link 207a opposite to the two sixth swing flange ends 207b via a threaded connector. On the side of the hook mounting bracket 207i opposite to the fifth link 207a, a first hook clamping member 207j and a second hook clamping member 207k are mounted via a threaded connector. Before the surgical procedure, the surgeon or assistant can select a surgical hook 3 of the corresponding specification according to the surgical requirements, and install the corresponding hook mounting bracket 207i onto the fifth link 207a according to the specifications of the selected surgical hook 3. The surgical hook 3 and the hook mounting bracket 207i are then fixed relative to each other via the first hook clamping member 207j and the second hook clamping member 207k.

[0029] The fifth link 207a of the third swing arm 207 is equipped with a control button 5 consisting of a first button 501 and a second button 502. The first button 501 and the second button 502 are electrically connected to multiple electromagnetic suction cups 4. The first button 501 energizes the electromagnetic suction cups 4, and the second button 502 energizes them. When the surgeon or assistant adjusts the angle of the auxiliary arm assembly 2, they can hold the fifth link 207a and de-energize the electromagnetic suction cups 4 using the first button 501. At this time, the joints in the auxiliary arm assembly 2 can rotate, slide, or swing according to their respective connections. After the surgeon or assistant adjusts the joints in the auxiliary arm assembly 2 to the target position, they energize the electromagnetic suction cups 4 at each joint using the second button 502. At this time, there is no relative movement at any joint in the auxiliary arm assembly 2, thus fixing the auxiliary arm assembly 2 in the target position.

[0030] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects: This application provides an auxiliary retractor operating table. During use, the surgeon or assistant can adjust the angle and height of each joint in the entire auxiliary arm assembly 2 by holding the third swing arm 207. This allows the surgical retractor 3 connected to the end of the third swing arm 207 to perform traction on the wound at the angle required by the surgeon. After the surgeon or assistant has adjusted the posture of the entire auxiliary arm assembly 2, they only need to use the control button 5 on the third swing arm 207 to simultaneously energize the electromagnetic suction cups 4 at each joint of the auxiliary arm assembly 2. At this time, the electromagnetic suction cups 4 at each joint can electromagnetically attract and fix each movable joint in the auxiliary arm assembly 2, thereby maintaining the entire auxiliary arm assembly 2 at the angle required by the surgeon for wound traction. By using the auxiliary arm assembly 2 to replace the assistant in performing traction on the surgical retractor 3, the phenomenon of changes in traction angle and force due to the assistant's physical exhaustion can be prevented, effectively reducing the assistant's workload and simultaneously improving the surgeon's surgical efficiency.

[0031] The above descriptions are merely some embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
