Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment technology, specifically to an elastic telescopic strap for an operating table. Background Technology

[0002] Restraint straps are devices used to protect patient safety during treatment, securing specific body parts, restricting limb movement, and reducing the risk of falls. Operating table restraints, on the other hand, are specifically designed to secure patients to the operating table during surgery, ensuring they remain in a safe position and preventing accidental movement, thus guaranteeing the smooth progress of the procedure and patient safety. Operating table restraints not only help reduce surgical risks but also improve surgical efficiency, making them an indispensable auxiliary device in modern operating rooms.

[0003] In clinical practice, medical staff use traditional restraint straps to cover the patient and then tie the ends of the straps to the fixation brackets on both sides of the operating table to ensure that the patient remains in a safe and stable position during surgery. However, traditional restraint straps have the following problems: 1) The length is fixed and cannot be adjusted. For larger patients, longer restraint straps need to be replaced, increasing the workload of medical staff; 2) The ends of the restraint straps are fixed to the fixation brackets by wrapping and knotting, which is not a secure connection and is prone to loosening and falling off, posing a safety hazard.

[0004] Therefore, how to design an elastic and retractable operating table strap that can adapt to patients of different body types is a technical problem that has not yet been solved in the existing technology. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the technical defect in the prior art that the traditional restraint belt has a fixed length, which requires larger patients to replace the restraint belt with one of different lengths, so as to provide an elastic telescopic restraint belt for operating tables that can adapt to patients of different body sizes.

[0006] Therefore, this utility model provides an elastic telescopic strap for an operating table, comprising two main components respectively adapted to be installed on fixed supports on both sides of the operating table; each main component includes: a retractable structure, which can be detachably installed on a fixed support on one side of the operating table via an installation structure; a restraint strap, one end of which is connected to the retractable structure and can be retracted or released via the retractable structure; and a limiting structure disposed on the retractable structure for locking the restraint strap; after the two restraint straps are extended, their other ends can be detachably connected via a buckle structure.

[0007] As a preferred embodiment, the retractable structure includes: a housing having an inner cavity and an elongated opening communicating with the inner cavity on one side; a fixed shaft fixedly disposed in the inner cavity, one end of which is fixed to the inner wall of the housing; and a coil spring wound around the outside of the fixed shaft, one end of which is connected to the constraint strap and the other end of which is connected to the fixed shaft.

[0008] As a preferred embodiment, the housing has an installation opening on its side that communicates with the inner cavity, and also includes a side cover plate that can be opened and closed to cover the installation opening and is fixedly connected by bolts.

[0009] As a preferred embodiment, the limiting structure includes: a vertical opening, formed above the elongated opening, vertically penetrating the shell and communicating with the upper end of the elongated opening; a limiting groove, with a circular cross-section, formed below the elongated opening and communicating with the lower end of the elongated opening through the limiting opening; a limiting insert plate, slidably installed in the vertical opening, with a limiting post integrally formed at the bottom; the limiting post is made of elastic plastic material, with an outer diameter slightly smaller than the inner diameter of the limiting groove and slightly larger than the width of the limiting opening; when the limiting insert plate is pressed, the limiting post undergoes elastic deformation under pressure, reducing its outer diameter, thereby allowing it to enter the limiting groove through the limiting opening; when the limiting post is fully inserted into the limiting groove, it elastically returns to its original outer diameter, the outer wall of the limiting post fits against the inner wall of the limiting groove, and the constraint band sandwiched between them is pressed and locked; when the limiting post moves upward from the limiting groove into the elongated opening, the locking of the constraint band can be released.

[0010] As a preferred embodiment, the mounting structure includes: a fixing member, which is an inverted U-shaped structure, with a through hole on one side; the through hole has an internal thread; a movable rod, which has an external thread, and the movable rod is screwed to the internal thread of the through hole through the external thread, with one end passing through the through hole and engaging with the other side of the fixing member, thereby clamping and fixing the fixing member to the fixed bracket of the operating table.

[0011] As a preferred embodiment, it also includes a movable seat, which is fixedly mounted on one end of the movable rod by a fixing screw.

[0012] As a preferred embodiment, the buckle structure includes a plug disposed on one of the main body components at the other end of the constraint band, and a socket disposed on the other end of the constraint band on another of the main body components; the plug is capable of being plugged into or disconnected from the socket.

[0013] As a preferred embodiment, it also includes two insert plate pull rods, which are arranged opposite each other at both ends of the limiting post to assist in lifting the limiting insert plate to release the locking of the constraint band.

[0014] As a preferred embodiment, the other end of the movable rod is provided with a torsion handle.

[0015] As a preferred embodiment, the restraint band is made of a tough fabric.

[0016] The technical solution provided by this utility model has the following advantages:

[0017] This utility model discloses an elastic telescopic strap for an operating table, comprising two main components adapted to be installed on fixed supports on both sides of the operating table. Each main component includes a retractable structure, a restraint strap, and a limiting structure. The retractable structure can be detachably installed on a fixed support on one side of the operating table via an installation structure. One end of the restraint strap is connected to the retractable structure and can be retracted or released via the retractable structure. The limiting structure is provided on the retractable structure for locking the restraint strap. After the two restraint straps are extended, their other ends can be detachably connected via a buckle structure.

[0018] When using the elastic telescopic restraint for the operating table of this invention, the patient first lies on the operating table. Then, the two main components are installed on the fixed supports on both sides of the operating table via the mounting structure. Next, the two restraint straps are connected together via a buckle structure, and the restraint straps are adjusted to a suitable length according to the patient's body shape. Then, the length of the restraint straps is locked by a limiting structure, thereby securing the patient to the operating table. After the surgery, the buckle structure is disconnected, and then the limiting structure is operated to release the restraint straps, which are then retracted into the retraction structure. This elastic telescopic restraint for the operating table of this invention can shorten or lengthen the restraint straps through the retraction structure, thus adapting to patients of different body shapes, avoiding the need to change restraint straps due to differences in patient body shape, and reducing the workload of medical staff. Furthermore, this invention uses a mounting structure to fix the restraint straps to the fixed supports of the operating table, ensuring a secure and reliable connection and avoiding the safety hazard of loosening and falling off the restraint straps.

[0032] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0033] This embodiment provides an elastic and retractable strap for an operating table, such as... Figure 1-2 and Figure 6 As shown, the device includes two main components 1 respectively mounted on fixed supports on both sides of the operating table. Each main component 1 includes: a retractable structure 4, a restraint strap 2, and a limiting structure 5. The retractable structure 4 can be detachably mounted on a fixed support on one side of the operating table via a mounting structure 3. One end of the restraint strap 2 is connected to the retractable structure 4 and can be retracted or released via the retractable structure 4. The limiting structure 5 is provided on the retractable structure 4 and is used to lock the restraint strap 2. When the two restraint straps 2 are extended, their other ends can be detachably connected via a buckle structure 6.

[0034] When using the elastic telescopic strap for the operating table in this embodiment, the patient first lies on the operating table. Then, the two main components 1 are installed on the fixed supports on both sides of the operating table via the mounting structure 3. Next, the two restraint straps 2 are connected together via the buckle structure 6. The restraint straps 2 are adjusted to a suitable length according to the patient's body shape. Then, the length of the restraint straps 2 is locked by the limiting structure 5, thereby securing the patient to the operating table. After the surgery, the buckle structure 6 is disconnected, and then the limiting structure 5 is operated to release the restraint straps 2, which are then retracted into the retraction structure 4. The elastic telescopic strap for the operating table in this embodiment can shorten or lengthen the restraint straps 2 via the retraction structure 4, thus adapting to patients of different body shapes. This avoids the need to change the restraint straps 2 due to differences in patient body shape, reducing the workload of medical staff. Furthermore, this embodiment uses the mounting structure 3 to fix the restraint straps 2 to the fixed supports of the operating table, ensuring a secure and reliable connection and preventing the safety hazard of the restraint straps 2 loosening and falling off.

[0035] like Figure 7-8 As shown, the retractable structure 4 includes a housing 41, a fixed shaft 42, and a coil spring 43. The housing 41 has an inner cavity 410, with an elongated opening 40 communicating with the inner cavity 410 on one side. The fixed shaft 42 is fixedly disposed within the inner cavity 410, with one end fixed to the inner wall of the housing 41. The coil spring 43 is wound around the outside of the fixed shaft 42, with one end connected to the constraint band 2 and the other end connected to the fixed shaft 42. Specifically, one end of the fixed shaft 42 is fixed to the inner wall of the housing 41, and the other end has a fixed opening along the axial direction. The coil spring 43 is sleeved on the outside of the fixed shaft 42, with its outer end fixedly connected to the constraint band 2 by rivets, and its inner end integrally formed with a fixed vertical plate, which can be installed in the fixed opening, thereby fixing the coil spring 43 to the fixed shaft 42. The constraint band 2 can automatically retract and adjust its length by means of the elastic deformation of the coil spring 43, simplifying operation and improving convenience.

[0036] The housing 41 has a mounting opening 411 on its side that communicates with the inner cavity 410, and also includes a side cover plate 44. The side cover plate 44 can be opened and closed to cover the mounting opening 411 and is fixedly connected by bolts. During installation, the side cover plate 44 is opened, and the coil spring 43 is inserted into the inner cavity 410 through the mounting opening 411; after installation, the side cover plate is closed and fixed with screws.

[0037] like Figure 4As shown, the limiting structure 5 includes a vertical opening 51, a limiting groove 52, and a limiting plate 53; wherein the vertical opening 51 is opened above the elongated opening 40, vertically penetrates the housing 41, and communicates with the upper end of the elongated opening 40; the limiting groove 52 has a circular cross-section, is opened below the elongated opening 40, and communicates with the lower end of the elongated opening 40 through the limiting opening 52; the limiting plate 53 is slidably installed in the vertical opening 51, and a limiting post 54 is integrally formed at the bottom; the limiting post 54 is made of elastic plastic material, with an outer diameter slightly smaller than the inner diameter of the limiting groove 52, and slightly larger than the inner diameter of the elongated opening 40. The width of the limiting opening 520 is described. When the limiting insert 53 is pressed, the limiting post 54 undergoes elastic deformation under pressure, reducing its outer diameter, thereby pressing the constraint band together through the limiting opening 520 into the limiting groove 52. After the limiting post 54 is fully inserted into the limiting groove 52, it elastically returns to its original outer diameter, and the outer wall of the limiting post 54 and the inner wall of the limiting groove 52 can press and lock the constraint band 2 sandwiched between them. When the limiting post 54 moves upward from the limiting groove 52 into the elongated opening 40, the locking of the constraint band 2 can be released. This design enables rapid locking and unlocking of the constraint band 2 and ensures the stability of the locking of the constraint band 2.

[0038] like Figure 5 As shown, the mounting structure 3 includes a fixing member 31 and a movable rod 32. The fixing member 31 has an inverted U-shaped structure with a through hole 310 on one side. The through hole 310 has an internal thread 311. The movable rod 32 has an external thread 321. The movable rod 32 is screwed to the internal thread 311 of the through hole 310 via the external thread 321. One end of the movable rod passes through the through hole 310 and engages with the other side of the fixing member 31, thereby clamping and fixing the fixing member 31 onto the fixed support of the operating table. In use, the fixing member 31 is first placed on the fixed support, and then the other end of the movable rod 32 is rotated. The one end of the movable rod 32 will move closer to the other side of the fixing member 31 under the action of the external thread 321 and the internal thread 311 until the fixing member 31 is clamped and fixed onto the fixed support of the operating table. This design allows the mounting structure 3 to be used with fixed supports of different sizes, improving its versatility.

[0039] It also includes a movable seat 33, which is fixedly mounted on one end of the movable rod 32 by a fixing screw 331. The movable seat 33 increases the contact area between the movable rod 32 and the fixing member 31, thereby improving the stability of the connection.

[0040] The buckle structure 6 includes a plug 61 disposed on the other end of the constraint band 2 on one of the main body parts 1, and a socket 62 disposed on the other end of the constraint band 2 on another of the main body parts 1; the plug 61 can be plugged into or disconnected from the socket 62.

[0041] like Figure 3 As shown, it also includes two insert plate pull rods 541, which are arranged opposite each other at both ends of the limiting post 54 to assist in lifting the limiting insert plate 53 to release the locking of the constraint band 2. This design makes it easier for medical staff to apply force when operating the limiting structure, reduces the difficulty of operation, and improves the convenience and flexibility of use.

[0042] The other end of the movable rod 32 is provided with a torsion handle 322, which allows medical staff to rotate the movable rod 32 more easily, making the installation process smoother.

[0043] The constraint band 2 is made of tough fabric. When pressing the limiting plate, the constraint band 2 can be pressed into the limiting groove more smoothly, avoiding jamming due to excessively hard material. This makes the operation of the limiting structure more effortless and convenient, while ensuring a tight fit between the constraint band and the limiting groove, thus improving the reliability of the locking state.

[0044] In this embodiment, the plug 61 and socket 62 use existing nylon snap fasteners, which are currently available devices on the market.

[0045] The elastic telescopic strap for the operating table in this embodiment is used as follows:

[0046] First, the patient lies on the operating table. Then, the fixing parts 31 of the two main components 1 are placed on the fixed support. Next, the other end of the movable rod 32 is rotated. One end of the movable rod 32 will move closer to the other side of the fixing part 31 under the action of the external thread 321 and the internal thread 311 until the fixing part 31 is clamped and fixed to the fixed support of the operating table. After fixing, the plugs 61 and sockets 62 at the ends of the two restraint straps 2 are connected together, and the restraint straps 2 are adjusted to a suitable length according to the patient's body shape. Then, the limiting plate 53 and the restraint straps 2 below it are pressed and clamped together in the limiting groove 52 to lock the restraint straps 2, thereby fixing the patient on the operating table. After the operation, the connection between the plugs 61 and sockets 62 is disconnected, the limiting plate 53 is pulled out, thereby releasing the restraint straps 2, and then the restraint straps 2 are retracted into the retraction structure 4.

[0047] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this innovative technical solution.
