Description

Technical Field

[0001] The present invention relates to a medical device, in particular to a surgical platform. Background Art

[0002] In the field of biomedical research, rats are widely used as key experimental animal models in surgical operations, such as drug metabolism and kinetics research, neurosurgical intervention, organ transplantation, and chronic disease model construction. However, the currently commonly used rat surgical fixation platform has a series of core defects that restrict experimental efficiency and reliability: the body position adaptability is highly limited, and traditional fixation plates usually only support a single supine or prone posture, which is difficult to flexibly switch according to the surgical site (such as supine for chest and abdominal cavity exposure, prone for brain stereotactic positioning), and there is a lack of special avoidance structures for rat models of intracranial implants (such as brain electrodes and catheters), which leads to compression and displacement of implants and even damage to brain tissue during supine surgery; the fixation stability is seriously insufficient, relying on simple binding limb fixation (such as elastic straps, L-shaped bayonet) and basic incisor hooks, which is difficult to effectively inhibit the relaxation sliding of rat muscles under anesthesia, especially in the separation of neck blood vessels, Delicate operations such as pituitary removal can easily lead to loss of critical surgical fields of view; the excreta contamination control mechanism is weak, and the existing sewage collection tank design has a limited coverage (can only receive hindquarters excreta), which cannot effectively deal with intraoperative saliva, blood or forequarters contamination, and the disassembly and cleaning process is cumbersome, significantly increasing the risk of surgical interruption and the probability of postoperative infection; the body adaptability is poor and the adjustment efficiency is low. Faced with the significant body length difference between SD rats and Wistar rats (up to 10 cm or more), the traditional slide-type limb fixation device relies on a manual knob to drive the slider, which is time-consuming to adjust and difficult to achieve quick locking. At the same time, there is a lack of modular quick-change accessory systems for different surgeries (such as kidney surgery requiring lumbar support and cervical surgery requiring a cervical table).

[0003] Furthermore, the life support system is severely disconnected. Gas anesthesia relies on external tubes and masks installed separately, occupying valuable surgical space and increasing operational complexity. Constant temperature maintenance is often achieved through passive heat conduction from a metal platform (such as aluminum), lacking uniform heat distribution. This can easily lead to localized hyperthermia (>39°C) or hypothermia (<36°C), compromising the physiological homeostasis of experimental animals and data accuracy. These systemic deficiencies not only significantly prolong preoperative preparation and intraoperative time but also directly impact surgical precision, model establishment success rate, and experimental reproducibility. Therefore, there is an urgent need to develop a multifunctional surgical platform that integrates rapid multi-position switching (supine / prone), adaptive intracranial implant avoidance, highly stable linked limb-head locking, fully removable contamination protection, wide-range body adaptation and modular quick assembly, as well as a built-in gas anesthesia interface and a distributed constant temperature system to comprehensively improve the standardization, safety, and efficiency of rat surgery.

DETAILED DESCRIPTION

[0018] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.

[0019] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0020] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values of the parts and steps set forth in these embodiments do not limit the scope of the present invention. Meanwhile, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to actual proportional relationships. In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary, rather than as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once an item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0021] like Figure 1-2 As shown: A multifunctional, fast-fixed, angle-adjustable, constant-temperature surgical platform for rats, comprising: a box 10, the surface of which is provided with a plurality of expansion modules 20; four movable devices 30, each of which is composed of a plurality of movable grooves of different sizes, and the movable devices 30 are arranged in the aforementioned box 10; a moving device 40, the moving devices are respectively fixedly arranged at the bottom of the four movable devices 30, an upper fixed plate 50, the upper fixed plate is fixedly connected to the moving device; a lower fixed plate 60, the lower fixed plate is fixedly connected to the bottom of the box 10; and a lifting device 70, the lifting device is arranged between the upper fixed plate and the lower fixed plate.

[0022] like Figure 3 As shown, the expansion module 20 includes a fixing column 201 and a fixing buckle 202. The fixing column is fixedly set on the box body 10, and the fixing buckle is movably connected to the fixing column. Both of them are designed to be conductors and can be used to transmit current and signals transmitted by the controller. The fixing buckle can be pulled out from the fixing column with force. Similarly, when installing, you only need to press the fixing buckle hard to fix it on the fixing column.

[0023] like Figure 4-6 As shown, the movable device 30 includes an inner movable groove 302, a middle movable groove 303, and an outer movable groove 304. Each of the three movable grooves is composed of a shell with a semi-hollowed bottom. The hollow space of the groove body and the bottom of the three movable grooves increases from the inside to the outside. A silicone pad 301 is provided on the top of the inner movable groove 302, and a pressure block 306 is provided at the bottom of the inner movable groove. The pressure block is movably connected to the inner movable groove 302 via a first spring 307. Rebound plates 305 are provided between each side wall of the inner movable groove, the middle movable groove, and the outer movable groove. The surgical platform also includes a leveling block 308, one end of which extends and connects to the movable groove, and the other end is fixedly connected to the movable device via a second spring 309.

[0024] During use, the rat's limbs are inserted into the inner movable groove 302 via the silicone pad 301. The presence of the pressure block 306 at the bottom of the inner movable groove provides a certain shock absorption effect and leaves a large amount of room for the rat's limbs to move, greatly reducing the mechanical rigidity of the limbs in the longitudinal direction. Because the movable groove is composed of movable grooves of different sizes, the inner, middle, and outer movable grooves can move relative to each other. In other words, the inner movable groove 302 can be offset within the middle movable groove 303, and similarly, the middle movable groove 303 can also be offset within the outer movable groove 304. This allows the rat's limbs to move back and forth horizontally at any angle. To further enhance the linearity of this movement, the sidewalls of each movable groove are provided with a rebound plate 305. Under the action of the rebound plate, the movement of the limbs is more like walking, which provides a certain resistance. At the same time, to simulate the walking posture of a rat on uneven roads, the balance block 308 and the second spring 309 can be adjusted to simulate bumpy roads on one hand, and smooth roads on the other hand.

[0025] like Figure 7 As shown, the mobile device 40 is composed of an I-shaped screw 401, which is equipped with motors. The motors include a first motor M1, a second motor M2, a third motor M3, and a fourth motor M4, each of which is independent of each other. Each motor includes a transverse motor 402 and a longitudinal motor 403, respectively, and is mounted on the I-shaped screws of the four mobile devices. Because each motor is independently controlled, the surgical platform can manually intervene in the movement of the rat's limbs. For example, the first motor can be fixed, and the second, third, and fourth motors can be adjusted to maintain the rat in a fixed posture.

[0026] like Figure 8 As shown, the lifting device includes multiple support arms 702 and multiple damping hinges 701, and the support arms are movably connected through the damping hinges to raise or lower the entire surgical platform to facilitate better operation by the surgeon.

[0027] like Figure 9-11 As shown, the expansion module 20 is connected to a surgical retractor 80, which includes a handle 803 that is movably fixed to a sleeve 804, a hook 802 at the top of the handle, and a steel wire 806 fixedly connected to the bottom; a rotating device 805 that is rotatably arranged at the bottom of the sleeve 804 and connected to the steel wire 801 at one end; and a hose 801 connected to the bottom of the sleeve 804. During use, the handle is placed in the sleeve, and then the rotating device is rotated. The rotating device drives the steel wire to tighten the wire, thereby fixing the handle to the sleeve. The presence of the hose ensures that the surgical retractor can move in any direction.

[0028] The expansion module is also connected to a camera, which is fixed to the expansion module through a hard hose; a lighting module, which uses full-spectrum Ra>95 lamp beads; an oxygen tube fixture, which is also equipped with a carbon dioxide monitoring device; an electrode needle, the bottom of which is connected to a universal hose, which is used to accurately stimulate small structures with microcurrent. A retractor can hook the rat's part to better expose the surgical field of view. Using a universal hose, the angle can be adjusted arbitrarily, and it can communicate with the controller to achieve microcurrent stimulation of traction structures, such as muscles and nerves. The camera interface is a hard hose with a standard camera screw interface, which can realize surgical video recording and photography. The lighting module uses full-spectrum Ra>95 lamp beads to achieve true color reproduction, and can adjust the focus or astigmatism to cope with different surgical scenarios. The oxygen tube fixture can realize oxygen supply to rats, is equipped with a carbon dioxide monitoring device, and is connected to the controller through contacts. The electrode needle uses a universal hose, the angle can be adjusted arbitrarily, and is equipped with a locking device to communicate with the controller to achieve microcurrent accurate stimulation of small structures, such as muscles and nerves. The surgical platform also includes a controller C connected to switches, motors, and an expansion module 20. The switches include a four-way master switch S and a first four-way switch S1, a second four-way switch S2, a third four-way switch S3, and a fourth four-way switch S4. The motors include a first motor M1, a second motor M2, a third motor M3, and a fourth motor M4, each of which is independent of each other. Each motor includes a transverse motor 402 and a longitudinal motor 403, which are respectively arranged on the I-shaped screws of the four moving devices 40. The first, second, third, and fourth four-way switches independently control the first, second, third, and fourth motors, respectively. The four-way master switch is used to simultaneously control the first, second, third, and fourth motors. This achieves synchronous movement and stretches or relaxes the rat's limbs.

[0029] The device also features a Bluetooth module, enabling communication with a computer and control via computer software. This includes controlling lighting, brightness, and convergence, as well as adjusting the motor. It generates microcurrent stimulation, adjusting and recording the voltage and waveform of the microcurrent. The contraction and contraction of the rat's muscles causes slight movement of the fixture, which in turn drives the motor, generating a weak current. The controller records the current waveform for electromyographic analysis, controlling the motor's movement.

[0030] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0031] For ease of description, spatially relative terms such as "above," "on the upper surface of," "on top of," and the like may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "on top of" another device or structure would then be positioned as "below" or "below" the other device or structure. Thus, the exemplary term "above" may include both the orientations of "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used herein should be interpreted accordingly.

[0032] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0033] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
