Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a support device for supporting medical devices. Background Technology

[0002] Cryotherapy is a technique that has developed alongside interventional tumor treatment and minimally invasive techniques. It is based on the principle that cells undergo irreversible damage at extremely low temperatures, forming ice crystals inside and outside the cells, leading to cell membrane rupture and cell death. Cryotherapy often uses ablation needles.

[0003] With the increasing demand for high-precision surgery, doctors hope to use medical imaging technologies such as CT and MRI before, during, and after cryotherapy to observe the positional relationship between the treatment area and the ablation needle, in order to effectively destroy tumors while minimizing damage to normal tissues. This requires that the ablation needle inserted into the patient's body be fixed in position during medical imaging without the doctor's hand. However, most ablation needles currently on the market are designed for doctor-handled operation and cannot achieve effective fixation during medical imaging without the doctor's hand. Utility Model Content

[0004] The purpose of this invention is to provide a support device for medical devices, which can be used to fix medical devices in place during medical imaging without the doctor holding them.

[0005] This utility model provides a support device for a medical device, comprising a base plate, a connecting unit, and a bracket. The bottom surface of the base plate is used to attach a support surface. The base plate has a load-bearing section. The load-bearing section extends through the base plate along its length and is used to support a human body placed on it along its length. The connecting unit faces the top surface of the base plate and is spaced apart from the base plate so that the space between them can accommodate the human body supported by the load-bearing section. The connecting unit is used to securely connect the object to be supported. The bracket connects the base plate and the connecting unit to fix the relative positions of the base plate and the connecting unit. The bracket connects the portion of the base plate outside the load-bearing section to avoid obstructing the human body supported by the load-bearing section.

[0006] The support device of this medical device can fix the medical device in place, and can be used to fix the medical device in place during medical imaging without the doctor holding it.

[0007] In another illustrative embodiment of the support device for a medical device, the base plate is configured to deform to attach to support surfaces of different shapes. This improves the applicability of the support device for the medical device.

[0008] In another illustrative embodiment of the support device for the medical device, the base plate is a thermoplastic base plate. This facilitates operation.

[0009] In another illustrative embodiment of the support device for the medical device, the support includes several support legs. One end of each support leg is fixedly connected to a base plate. The other end of each support leg is rotatably connected to a connecting unit so that its posture can be adjusted according to the deformation of the base plate. This structure is simple and has good stability.

[0010] In another illustrative embodiment of the support device for the medical device, the support device further includes a positioning element. The positioning element is connected to the base plate. The positioning element is capable of adsorbing and / or sticking to the support surface to fix the position of the base plate on the support surface. This helps to prevent unintended displacement of the support device for the medical device during use.

[0011] In another illustrative embodiment of the support device for a medical device, the connecting unit includes a connecting seat, an angle adjusting member, and a connecting head. The connecting seat is connected to a bracket. The angle adjusting member is rotatably connected to the connecting seat. The connecting head is connected to the angle adjusting member and used to fix the object to be supported. The position and angle of the connecting head can be adjusted by the angle adjusting member.

[0012] In another illustrative embodiment of the support device for the medical device, the connecting unit further includes a support rod. The angle adjustment member and the connector are interconnected via the support rod. At least a portion of the support rod has a telescopic rod structure. This increases the dimensionality of position adjustment of the connector.

[0013] In another illustrative embodiment of the support device for a medical device, the connector includes a main body and a connecting member. The main body connects to an angle adjustment member. The connecting member is in the form of a curved plate extending along a planar curve. The two ends of the connecting member along its extension trajectory are fixed sections connecting to the main body. A connecting section is provided between the two fixed sections of the connecting member. The connecting section is bent to form a receiving groove. The connecting section can fix the object to be supported, inserted into the receiving groove, through its own plastic deformation. This allows for adaptation to objects of different shapes.

[0014] In another illustrative embodiment of the support device for the medical device, the main body has two connecting arms. Each connecting arm has a slot. The fixing section has a wavy structure. Each fixing section is inserted into a slot and elastically abuts against the slot wall through the protrusions of its wavy structure. This structure is simple and easy to assemble.

[0015] In another illustrative embodiment of the support device for the medical device, the connecting section has a wavy structure. This facilitates operation. Attached Figure Description

[0049] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, specific embodiments of the present utility model are now described with reference to the accompanying drawings. In the drawings, the same reference numerals indicate components with the same or similar structures but the same function.

[0050] In this document, “illustrative” means “serving as an example, illustration or description”, and any illustration or implementation described herein as “illustrative” should not be construed as a more preferred or advantageous technical solution.

[0051] To keep the drawings simple, each drawing only schematically shows the parts related to this utility model, and they do not represent the actual structure of the product.

[0052] Figure 1 This is a schematic structural diagram illustrating one embodiment of a support device for a medical device. This support device is used, for example, to secure an ablation needle inserted into a patient during medical imaging, but is not limited thereto; it can also be used to secure other medical devices. Figure 1 As shown, the support device for the medical device includes a base plate 10, a connecting unit 40, and a bracket 30.

[0053] Figure 2 for Figure 1 The diagram shows the usage status of the support device for the medical device. (See diagram for example.) Figure 2 As shown, the bottom surface of the base plate 10 is used to attach a support surface F. The support surface F is, for example, the bed surface of a medical bed for supporting a patient. The medical bed is, for example, an examination bed of a medical imaging system. The medical imaging system is, for example, an X-ray imaging system, a computed tomography (CT) system, a magnetic resonance imaging (MRI) system, an ultrasound imaging system, a nuclear medicine imaging system, etc., but is not limited to these.

[0054] like Figure 1 As shown, the base plate 10 has a load-bearing section 11 ( Figure 1The area between the two parallel dotted lines is the load-bearing section 11. The load-bearing section 11 extends through the base plate 10 along the length direction L and is used to support the human body 100 placed on it along the length direction L (see...). Figure 2 In use, the base plate 10 is placed, for example, under the patient's body. Figure 1 and Figure 2 As shown, the connecting unit 40 faces the top surface of the base plate 10 and is spaced apart from the base plate 10 so that the human body 100 supported by the bearing section 11 can be accommodated between them. The connecting unit 40 is used to fix the object to be supported. The object to be supported is, for example, an ablation needle, but is not limited to this.

[0055] The bracket 30 connects the base plate 10 and the connecting unit 40 to fix the relative positions of the base plate 10 and the connecting unit 40. The bracket 30 connects the portion of the base plate 10 located outside the load-bearing section 11 to avoid the human body supported by the load-bearing section 11.

[0056] During medical imaging, the support device of the medical device can be placed on the medical bed of the medical imaging system. The patient lies on the base plate 10 along the length L and is located between the base plate 10 and the connecting unit 40. The medical device acting on the patient (e.g., an ablation needle) is fixed to the connecting unit 40. The support device of the medical device can achieve the fixation of the medical device.

[0057] In the illustrative embodiment, the base plate 10 is configured to deform to attach to support surfaces of different shapes. This deformation can be, for example, plastic deformation. This improves the applicability of the support device for medical devices.

[0058] Furthermore, in the illustrative embodiment, the base plate 10 is a thermoplastic base plate, that is, the base plate 10 is made of a thermoplastic material with a glass transition temperature, for example, between 40°C and 80°C, but not limited to this. Each time it is used, the base plate 10 can be heated to soften it, and then manually pressed onto the support surface. After it cools and hardens, it can be used for stable support. This facilitates operation.

[0059] In an illustrative embodiment, the support device of the medical device may include, for example, a flexible electric heating pad that can be laid on the surface of the base plate 10, which can generate heat when energized to soften the base plate 10.

[0060] like Figure 1 As shown, in the illustrative embodiment, the support 30 includes four support legs 31. The support legs 31 are, for example, in the shape of bent rods. One end of each support leg 31 (i.e....) Figure 1 The lower end of each support leg 31 is fixedly connected to the base plate 10. Figure 1 The upper end of the base plate 10 is rotatably connected to the connecting unit 40 so that the posture can be adjusted as the base plate 10 deforms. Figure 3 for Figure 1A top view of the support device for the medical device shown. Figure 4 for Figure 3 An enlarged view of Part IV. Specifically, as shown... Figure 4 As shown, in this illustrative embodiment, four support legs 31 are rotatably connected to the connecting unit 40 about axes Z1, Z2, Z3, and Z4, respectively. Axes Z1, Z2, Z3, and Z4 are, for example, approximately perpendicular to the thickness direction of the base plate 10 in its flat state (i.e.,...). Figure 1 (As shown in the diagram, in the vertical direction). Thus, when the base plate 10 deforms according to the shape of the supporting surface, the four supporting legs 31 can adapt to the deformation of the base plate 10 by rotating relative to the connecting unit 40. This structure is simple and has good stability.

[0061] In other illustrative embodiments, the number of support legs 31 of the bracket 30 can be adjusted as needed, for example, not less than three.

[0062] like Figure 1 As shown in the illustrative embodiment, the support device of the medical device also includes four connectors 50. Each connector 50 is fixedly connected to the base plate 10. One end of each support leg 31 (i.e. Figure 1 The lower end of the support leg 31 can be plugged into a connector 50. This allows for easy removal of the support leg 31 from the base plate 10. In use, for example, the base plate 10 can be placed on the support surface first, then the patient can lie on the base plate 10, and then the support leg 31 can be installed. After use, it can be removed in reverse. This improves the ease of use of the support device for medical devices.

[0063] like Figure 1 and Figure 3 As shown in the illustrative embodiment, the support device of the medical device further includes two positioning fasteners 60. The positioning fasteners 60 are connected to the base plate 10. The positioning fasteners 60 are capable of adsorbing and / or sticking to the support surface to fix the position of the base plate 10 on the support surface. This helps to prevent unintended displacement of the support device of the medical device during use. Specifically, in this illustrative embodiment, the positioning fasteners 60 are suction cups; in other illustrative embodiments, the positioning fasteners 60 may also be silicone pads, but are not limited thereto. In other illustrative embodiments, the number of positioning fasteners 60 can be adjusted as needed.

[0064] like Figure 1As shown in the schematic embodiment, the connecting unit 40 includes a connecting seat 44, an angle adjusting member 41, a support rod 42, and a connector 43. The connecting seat 44 is connected to the support leg 31 of the bracket 30. In this embodiment, the angle adjusting member 41 can be, for example, a universal joint. Typically, a universal joint has an input shaft and an output shaft; here, we do not distinguish between them and refer to both shafts as connecting shafts. One of the connecting shafts of the universal joint is rotatably connected to the connecting seat 44 along its own axis Z5. One end of the support rod 42 is fixedly connected to the other connecting shaft of the universal joint. The connector 43 is connected to the other end of the support rod 42 and is used to fix the object to be supported. The position and angle of the connector 43 can be adjusted via the universal joint.

[0065] In the illustrative embodiment, the rotational position is locked between the movable parts of the angle adjusting member 41 and between the angle adjusting member 41 and the connecting seat 44, for example, by a locking member. Figure 5 As shown, the locking element 70, for example, is a structure that serves as a pivot in the rotational relationship by being sleeved and threaded together. Tightening the locking element 70 (by...) Figure 5 The state change shown in A is as follows: Figure 5 As shown in Figure B, the locking member 70 can be abutted against a structure that acts as a bushing in the rotational relationship, thereby locking the rotational position. In other illustrative embodiments, rotational position locking can also be achieved using other structures known in the art.

[0066] In other illustrative embodiments, the angle adjustment element 41 may be replaced, for example, with a spherical substructure.

[0067] In other illustrative embodiments, the support rod 42 may be omitted if necessary, and the angle adjustment member 41 and the connector 43 may be directly connected instead.

[0068] like Figure 1 As shown, in the illustrative embodiment, the support rod 42 is a telescopic rod structure. This increases the dimensionality of position adjustment of the connector 43. In other illustrative embodiments, the support rod 42 may also have a telescopic rod structure partially provided. In other illustrative embodiments, the support rod 42 may also be configured to be assembled from splicing modules in a free splicing method similar to Lego bricks. By adjusting the number, type, or splicing method of the splicing modules, the extension length of the support rod 42 can be changed or the angle can be increased or decreased (for example, some splicing modules have angles).

[0069] In the illustrative embodiment, the telescopic rod structure achieves position locking, for example, through an existing locking structure (such as the locking structure disclosed in publication number CN210338183U), after which the telescopic rod cannot continue to move. However, it is not limited to this; in other illustrative embodiments, the position locking of the telescopic rod can also be achieved through other existing structures.

[0070] In an illustrative embodiment, connector 43 is detachably connected to support rod 42, for example. Specifically, connector 43 is detachably inserted into the end of support rod 42 and secured to it by a snap-fit ​​structure, but is not limited thereto. In other illustrative embodiments, connector 43 may also be fixedly connected to the end of support rod 42. Alternatively, in other illustrative embodiments, connector 43 may also be rotatably connected to the end of support rod 42 via a spherical joint structure to provide more adjustment options.

[0071] Figure 6 for Figure 1 The diagram shows the structure of the connector. Figure 7 for Figure 1 The exploded view of the connector shown. Figure 8 for Figure 1 A partial cross-sectional view of the connector shown. (See attached image.) Figures 6 to 8 As shown in the schematic embodiment, the connector 43 includes a main body 431 and a connector 432. The main body 431 connects to the support rod 42, and the connection method is, for example, but not limited to, a plug-in connection. The connector 432 is in the form of a curved plate extending along a planar curve. At both ends of the connector 432 along its extension trajectory are two fixed segments P1 connecting to the main body 431. A connecting segment P2 is provided between the two fixed segments P1 of the connector 432. The connecting segment P2 is bent to form a receiving groove G. The connecting segment P2 can fix the object to be supported inserted into the receiving groove G through its own plastic deformation. This allows for the adaptation to objects of different shapes.

[0072] The connector 432 is made of, for example, a thermoplastic material, and its glass transition temperature is, for example, between 40°C and 80°C. Each time it is used, the connecting segment P2 of the connector 432 can be heated to soften it. Then, the object to be supported is inserted into the receiving groove G, and the softened connecting segment P2 is manually bent to deform it to fit the shape of the object to be supported. After it cools and hardens, it can be used to stably connect the object to be supported.

[0073] In an illustrative embodiment, the support device of the medical device may further include, for example, a heating element capable of enclosing the connecting segment P2 of the connector 432, which can provide heat to the connecting segment P2 to soften it. This heating element may be flexible and electrically heated.

[0074] like Figures 6 to 8 As shown in the schematic embodiment, the main body 431 has two connecting arms 4311. Each connecting arm 4311 has a slot S. The fixing segment P1 has a wavy structure. Each fixing segment P1 is inserted into a slot S and elastically abuts against the wall of the slot S through the protrusions of its wavy structure to fix the relative position of the main body 431 and the connector 432. This structure is simple and easy to assemble. The connector 432 is, for example, a disposable medical device.

[0075] In the illustrative embodiment, the connecting segment P2 has a wavy structure. Each time it is used, the connecting segment P2 of the connector 432 can be heated until softened. The softened connecting segment P2 maintains its wavy structure without external force (i.e., the softened connecting segment P2 maintains its wavy structure when the user does not squeeze it). Then, the object to be supported is inserted into the receiving groove G, and the softened connecting segment P2 is manually bent so that the protruding part of its wavy structure contacts the surface of the object to be supported. After it cools and hardens, it can be used to stably connect the object to be supported. This facilitates operation.

[0076] In an illustrative embodiment, the support device of the medical device is made of, for example, a non-metallic material. Non-metallic materials have the advantages of being non-magnetic and having low density, which helps to avoid affecting the imaging results during CT and MRI imaging.

[0077] It should be understood that although this specification is described according to various embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0078] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. All equivalent implementation schemes or modifications made without departing from the spirit of the present utility model, such as combinations, divisions or repetitions of features, should be included within the scope of protection of the present utility model.
