Description

Technical Field

[0001] This utility model belongs to the field of treatment equipment technology, and specifically relates to a fixation device. Background Technology

[0002] In craniocerebral surgeries and treatments, precise head fixation is a crucial technical aspect to ensure surgical accuracy and treatment outcomes. Specifically, in current treatment procedures, patients typically lie on a treatment table with their heads fixed using traditional head pins or thermoplastic mesh materials for craniocerebral surgery.

[0003] However, traditional head pin fixation requires directly screwing the cranial implant into the patient's skull to achieve a rigid connection. Therefore, this approach carries a high surgical risk and is not conducive to multiple fixations of the patient's head during multiple treatments. Furthermore, the thermoplastic mesh material used in fixation lacks rigidity, which causes slight head and body swaying even when the patient is fixed. This swaying not only reduces the accuracy of target area positioning during treatment but also affects patient safety and treatment effectiveness, thereby reducing the treatment outcome.

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] It is understood that the specific embodiments and accompanying drawings described herein are merely for explaining the present invention and are not intended to limit the present invention.

[0034] It is understood that, without conflict, the various embodiments of this utility model and the features thereof can be combined with each other.

[0035] It is understood that, for ease of description, the accompanying drawings of this utility model only show the parts related to the embodiments of this utility model, while the parts unrelated to the embodiments of this utility model are not shown in the drawings.

[0036] It is understood that, without conflict, the functions and steps marked in the flowcharts and block diagrams of the embodiments of this utility model may occur in a different order than that marked in the accompanying drawings.

[0037] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.

[0038] This embodiment provides a fixation device that can be used to fix the human body, specifically in a treatment system for cranial and brain treatment, such as a transcranial ultrasound device ultrasound treatment system.

[0039] like Figures 1 to 6 As shown, the fixation device proposed in this embodiment includes a support base 1, a flexible molded bag 2, a strap assembly 3, and a head fixation assembly 4. The support base 1 has a support surface, specifically, for example, a horizontal surface. The head fixation assembly 4 is used to fix the patient's head. The head fixation assembly 4 is fixedly connected to the support base 1. It is easy to understand that the head fixation assembly 4 is fixed on the support base 1 at a position corresponding to the patient's head. Taking a rectangular support base 1 as an example, the head fixation assembly 4 can be fixed at the position of one of the shorter sides of the rectangular support base 1, so that the patient's body has sufficient extension space when lying on the support base 1.

[0040] like Figure 1 and Figure 2As shown, a flexible molding bag 2 is disposed on the support surface. The interior of the flexible molding bag 2 has a filling space for foam material to expand and take shape. Specifically, the patient can lie on the side of the flexible molding bag 2 away from the support surface, allowing the foam material to expand and form a shape corresponding to the patient's body. This is equivalent to forming a groove that closely matches the patient's body shape. This groove has multiple surfaces that can support multiple sides of the patient's torso, such as the hips, waist, and armpits, thereby fixing the patient's body in multiple directions parallel to the support surface to prevent lateral movement. Moreover, because the shape of the foam material after foaming conforms closely to the patient's body, the flexible molding bag 2 filled with foam material can effectively improve the patient's lying comfort.

[0041] like Figure 1 and Figure 5 As shown, the strap assembly 3 includes multiple straps 31, at least one end of each strap 31 is fixedly connected to the support base 1; the multiple straps 31 and the support surface form a binding space for fixing the patient's torso, so that the patient is pressed onto the flexible molded bag 2 and the support base 1 by the multiple straps 31, thereby fixing the patient's torso in a direction perpendicular to the support base 1 by the cooperation of the multiple straps 31 with the support base 1 and the molded foam material.

[0042] The fixation device proposed in this embodiment, by combining the support base 1, the flexible molding bag 2, and the strap assembly 3, can fix the patient's body from multiple directions. It can then work with the head fixation assembly 4 to fix the patient as a whole, preventing the patient's head from moving due to body movement during treatment. This improves the reliability of the patient's head fixation, thereby enhancing the safety and effectiveness of the treatment and helping to improve the accuracy of the treatment. For example, it can improve the alignment accuracy between the focus point of the ultrasound treatment signal and the target point inside the patient's brain.

[0043] Specifically, foamed materials can undergo a gas-generating reaction under the catalysis of a catalyst or heating. The generated gas creates voids within the foamed material, thereby achieving volume expansion and completing the foaming process. Furthermore, foamed materials can be, for example, polyurethane foamed materials, epoxy resin-based foamed materials, and other similar materials.

[0044] For example, before foaming, the operator can first flatten the surface of the flexible molded bag 2 so that the thickness of the foam material in the flexible molded bag 2 is uniform in the direction perpendicular to the bearing surface. For example, a long rod-shaped tool can be used to roll the foam material evenly so that the foam material under the patient's body is evenly distributed, so that the side of the patient's body can contact the lying groove formed by the foam material as much as possible, so as to fully restrict the lateral movement of the patient's body.

[0045] For example, such as Figure 1 As shown, the length of the flexible molding bag 2 is approximately equal to the distance from the patient's neck to the thigh after foaming and molding, and the width of the flexible molding bag 2 is approximately equal to the width of the patient's shoulder after foaming and molding.

[0046] In some embodiments, the flexible molded bag 2 includes at least one waterproof layer and at least one heat insulation layer to prevent leakage of the foam material and to prevent the patient from feeling uncomfortable due to heat generation during the foaming process.

[0047] In some embodiments, such as Figure 2 and Figure 3 As shown, the flexible molding bag 2 has at least one connecting port 21. When open, each connecting port 21 connects to the filling space and the external environment, respectively, to allow gas and / or foaming material to pass through. Specifically, the connecting port 21 can be used to expel residual gas in the flexible molding bag 2 before the foaming material foams, to avoid air mixing in the foaming material, which would result in large pores in the final foamed lying pad, thus affecting the support strength of the lying pad. Moreover, when it is necessary to increase or decrease the amount of foaming material, such as when the patient is too large or too small, foaming material can be added to the flexible molding bag 2 or some foaming material can be discharged from the flexible molding bag 2 through the connecting port 21.

[0048] In some embodiments, a first connecting portion 22 is provided on the side surface of the flexible molded bag 2 facing the support base 1, and a second connecting portion 11 is provided on the side surface of the support base 1 facing the flexible molded bag 2. The first connecting portion 22 and the second connecting portion 11 are detachably connected so that the flexible molded bag 2 is detachably fixed on the support base 1, thereby allowing the flexible molded bag 2 to be replaced when it is damaged or when different patients are treated.

[0049] Furthermore, in some embodiments, such as Figure 3 and Figure 4 As shown, one of the first connecting part 22 and the second connecting part 11 includes at least one protruding structure, and the other includes a groove structure corresponding to the protruding structure. The protruding structure and the corresponding groove structure are inserted and matched to fix the flexible molded bag 2 on the support base 1 through the insertion. This allows different flexible molded bags 2 to be located at the same position in the support surface, so that different patients are located at the same position in the support surface. This enables the edge operator to quickly find the target point of the patient to be treated during the treatment process.

[0050] Furthermore, in some embodiments, such as Figure 4As shown, there are multiple protrusion structures, including at least one first strip protrusion 111 extending along the first direction X and at least one second strip protrusion 112 extending along the second direction Y; there is an angle between the first direction X and the second direction Y to restrict the flexible molded bag 2 in directions perpendicular to the first direction X and the second direction Y.

[0051] For example, such as Figure 4 As shown, the first direction X and the second direction Y can both be parallel to the bearing surface.

[0052] For example, such as Figure 4 As shown, multiple protruding structures are provided on the bearing surface, and correspondingly, the flexible molded bag 2 has multiple groove structures on the surface facing the bearing surface. Moreover, the bearing surface is rectangular, with the first direction X and the second direction Y parallel to the two sides of the bearing surface, respectively.

[0053] In some embodiments, each of the multiple straps 31 has a first end and a second end. For example... Figure 1 As shown, the first end of each strap 31 is connected to the support base 1, and the second ends of multiple straps 31 are interconnected, so that the multiple straps 31 are arranged radially, thereby providing binding forces to the patient in multiple different directions. Moreover, the first ends of at least two of the multiple straps 31 are located on both sides of the flexible molded bag 2 to fix the patient's waist. Furthermore, the first end of at least one of the multiple straps 31 is located on the side of the flexible molded bag 2 near the head fixation component 4, and the first end of at least one of the multiple straps 31 is located on the other side of the flexible molded bag 2 near the head fixation component 4, so that at least two straps 31 are connected to both sides of the head fixation component 4. Thus, when the patient is fixed by the fixation device, at least two straps 31 can extend from near the patient's shoulders to near the torso, thereby strengthening the fixation of the patient's shoulders and further improving the reliability of the fixation of the patient's head.

[0054] For example, such as Figure 5 As shown, the bandage assembly also includes a buckle 33. The second ends of the multiple bandages 31 can be connected to each other via the buckle 33, so that the multiple bandages 31 can be released simultaneously using the buckle 33, so that the multiple bandages 31 can be quickly untied after the treatment is completed.

[0055] For example, such as Figure 1As shown, the strap assembly 3 includes two first straps 31a and two second straps 31b. Specifically, the first ends of both first straps 31a are connected to the middle region of the support base 1, and the first ends of the two first straps 31a are respectively located on both sides of the flexible molded bag 2. The first ends of the two second straps 31b are spaced apart, and the first ends of the two second straps 31b are respectively located on the side of the flexible molded bag 2 closer to the patient's head; the second ends of the two first straps 31a and the second ends of the two second straps 31b are connected to each other.

[0056] For example, the first ends of the multiple straps 31 can be fixed to the support base 1 with screws.

[0057] In some embodiments, such as Figure 5 As shown, each of the multiple straps 31 is provided with a length adjustment element 32, which is used to adjust the length of the corresponding strap 31 so that the length of the corresponding strap 31 can be adjusted to fit the patient's body shape, and the patient's body can also be tightened by adjusting the length of the strap 31.

[0058] In some embodiments, as shown in the figure, the head fixation assembly 4 includes a head clamping component 41 and a fixation bracket 42. The head clamping component 41 has a clamping space for clamping and fixing the patient's head. The fixation bracket 42 is connected to the head clamping component 41 and the support base 1 respectively, for fixing the relative position of the head clamping component 41 and the support base 1.

[0059] For example, such as Figure 6 As shown, the head clamping component 41 includes a first thermoplastic plate and a second thermoplastic plate; the first thermoplastic plate is formed by pressing onto the patient's face to conform to the shape of the patient's face; the second thermoplastic plate is formed by pressing onto the back of the patient's head to conform to the shape of the back of the patient's head; the first thermoplastic plate and the second thermoplastic plate are clamped relative to each other on the front and back sides of the patient's head, and the adjacent ends of the first thermoplastic plate and the second thermoplastic plate are connected and fixed by a mounting assembly to clamp and fix the patient's head.

[0060] For example, the head-holding component 41 may further include a conformal mask and a conformal headrest. The conformal mask is used to fix the patient's face; the conformal mask can be manufactured using a 3D printing process to conform to the shape of the patient's face, thereby fixing the patient's face by conforming to the protruding surface of the patient's face. The conformal headrest is used to support and fix the back of the patient's head; the conformal headrest can be manufactured using a 3D printing process or made from a headrest bag filled with foam material, so that the surface of the conformal headrest conforms to the shape of the back of the patient's head, thereby achieving stable support for the patient's head and improving patient comfort.

[0061] In some embodiments, such as Figure 6As shown, the fixing bracket 42 includes a crossbeam structure 421, two support column structures 422, and two cantilever structures 423. The two support column structures 422 are disposed on one side of the crossbeam structure 421, and one end of each support column structure 422 is connected to both ends of the crossbeam structure 421, forming a "U"-shaped structure. Furthermore, the crossbeam structure 421 and the two support columns can enclose a hollow area with a top opening, which can accommodate the head clamping component 41, thereby accommodating the back of the patient's head. The other ends of the two support column structures 422 are connected to the two cantilever structures 423, which are connected to the head clamping component 41. Specifically, the two cantilever structures 423 are used to connect and fix to both ends of the head clamping component 41.

[0062] For example, the two cantilever structures 423 can be bolted together with the head clamping component 41 to achieve a detachable connection.

[0063] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
