Description

Technical Field

[0001] This utility model relates to the field of cervical spondylosis research technology, specifically to a limb fixation device for imaging the cervical spine of mice. Background Technology

[0002] In research on cervical spondylosis, researchers need to establish a rat-assisted model. By taking photos of rats from multiple angles and positions, they can simulate the angle selection used when taking X-rays of patients with cervical spondylosis, thus meeting the detection requirements in basic experimental procedures for cervical spondylosis.

[0003] In traditional methods, when photographing rats in prone and lateral positions, the limbs of the anesthetized rats are manually adjusted and fixed to the desired state. Especially in the lateral position, it is necessary to photograph the rat's head from different angles (upward, downward, and sideways). The rat's head is not easy to fix, and other methods of fixation, such as tape, can easily damage the rat's normal physiological tissues. Moreover, the uncertainty of the fixation position leads to inconsistent overall data results, affecting the experimental process and results.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a limb fixation device for imaging the cervical spine of mice. Utility Model Content

Detailed Implementation

[0025] 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.

[0026] like Figure 1-5As shown, a limb fixation device for imaging the cervical spine of a mouse includes a fixing platform 1 and a limiting member 2. The limiting member 2 is installed in the middle of the top surface of the fixing platform 1, and a label 3 is installed at one corner of the top surface of the fixing platform 1. A supplementary light 4 is provided in the middle of one end of the top of the fixing platform 1, and fixing corner plates 5 are symmetrically arranged on the left and right sides of the fixing platform 1. The limiting member 2 includes a limiting strap 201, a fixing rod 202, and an anti-slip pad 203. The fixing rod 202 is vertically arranged at both ends of the limiting strap 201, and the lower end surface of the fixing rod 202 is covered with an anti-slip pad 203. The fixing platform 1 includes an operating... The operating platform 101 includes a placement area 102, an adjustment socket 103, and a frame 104. The placement area 102 is located at the top center of the operating platform 101, and the adjustment socket 103 is located around the placement area 102. A frame 104 is located at one corner of the top surface of the operating platform 101. The two ends of the limiting strap 201 are connected to the upper end of the fixed rod 202 by a sleeve structure. The limiting strap 201 is made of elastic material. The inner surface structure of the adjustment socket 103 matches the outer surface structure of the lower end of the fixed rod 202. The anti-slip pad 203 is made of rubber and is tightly attached to the lower surface of the fixed rod 202.

[0027] Specifically, since a rectangular ring structure with equidistantly spaced adjustment holes 103 is used around the placement area 102, when the rat is placed in the middle of the placement area 102, two sets of fixing rods 202 are vertically inserted into the adjustment holes 103. The two ends of the limiting straps 201 are respectively fitted onto the upper ends of the two sets of fixing rods 202. Using this structure, the rat's position can be adjusted within a certain adjustable range according to its size, thus maximizing the limitation and fixation of the rat's body. This ensures that the rat can be more accurately photographed in prone and lateral positions after anesthesia, and also ensures the usability of the device structure. The design offers flexibility and ease of use. Furthermore, an anti-slip pad 203, made of rubber, is affixed to the lower surface of the fixed insertion rod 202. This design ensures the stability and firmness of the fixed insertion rod 202 when inserted into the adjustment hole 103 without affecting the insertion of the structure into the fixed insertion rod 202 and the operating platform 101. Combined with a limiting strap 201 made of elastic material, this design minimizes unnecessary damage to the rat's body tissues while ensuring the safety of the structure and the effectiveness of the limiting mechanism. This significantly improves imaging quality, reduces operation time, and increases experimental efficiency and data accuracy.

[0028] Furthermore, the adjustment sockets 103 are arranged in a rectangular structure at equal intervals around the placement area 102. The insertion frame 104 and the operating table 101 are integrated into one structure. The insertion frame 104 is arranged in a horizontal "U" shape. The label card 3 is arranged in a sliding insertion structure inside the insertion frame 104.

[0029] Specifically, an insertion frame 104 is provided at one corner of the top surface of the operating platform 101. The insertion frame 104 adopts a horizontal "U"-shaped structure, which allows the label card 3 to be inserted horizontally. This enables a quick insertion and removal of the two components. Using the structure of the label card 3, auxiliary labels can be written on its surface. This method can help record data labels in the images of rats, improve image recognition, and facilitate subsequent image retrieval and organization. In addition, since the insertion frame 104 and the label card 3 are located at one corner of the top surface of the operating platform 101, this structural arrangement can minimize unnecessary interference with rat photography and ensure the convenience and flexibility of the structural components.

[0030] Furthermore, the fixed platform 1 also includes a docking groove 105 and a connecting groove 106. The docking groove 105 is provided at the center of one end of the top surface of the operating platform 101, and the connecting grooves 106 are symmetrically provided on the front and back sides of the operating platform 101. The supplementary light 4 includes a stabilizing platform 401, a flexible support rod 402, and a lamp head 403. The flexible support rod 402 is installed in the middle of the top of the stabilizing platform 401, and the lamp head 403 is installed at the end of the flexible support rod 402 away from the stabilizing platform 401. Holes for bolt installation are provided at the four opposite corners of 1, and the inner surface structure of the docking groove 105 matches the bottom surface structure of the stabilizing platform 401. The flexible support rod 402 is made of flexible material that can be bent and adjusted, and the lamp head 403 is fixedly connected to the flexible support rod 402. The inner surface structure of the connecting groove 106 matches the side surface structure of the fixed angle plate 5, and the fixed angle plate 5 is symmetrically arranged on the side of the operating platform 101 and is movably connected to each other.

[0031] Furthermore, by symmetrically providing connecting grooves 106 on both the left and right sides of the operating platform 101, and by matching the inner surface structure of the connecting grooves 106 with the side surface structure of the fixing angle plate 5, and using bolts, the fixing angle plate 5 can be fixed to the side of the fixing platform 1. Simultaneously, the entire fixing platform 1 can be connected and fixed to the operating table surface. Using this structure, the entire device can be structurally fixed to the maximum extent, ensuring the structural stability of the device and avoiding any impact on the photography of the rats. Additionally, the supplementary lighting 4... The structure is designed such that the stabilizing platform 401 and the docking groove 105 fit together to install the entire supplementary light 4 at one end of the fixed platform 1. At the same time, the stabilizing platform 401 has holes at the four opposite corners for bolt installation. With the use of bolts, the entire supplementary light 4 can be further fixed. The flexible support rod 402 can be bent and adjusted to adjust the orientation of the lamp head 403. The structure of the entire supplementary light 4 can provide good structural lighting for rat examinations and other operations when X-ray imaging is not being performed, thus ensuring ease of operation.

[0032] Working principle: When it is necessary to fix the limbs of the rat, the rat is first anesthetized. During this process, the four sets of fixing angle plates 5 are respectively connected to the connecting grooves 106 opened on both sides of the operating table 101, and the entire fixing table 1 is fixed on the operating table surface in conjunction with the use of bolts to ensure the stability of the device structure.

[0033] After the anesthetic takes effect, the rat is placed in the middle of the placement area 102. Then, the rat is positioned in a prone or lateral position as needed. Next, the two ends of the restraint strap 201 are respectively attached to the upper sections of the two sets of fixing rods 202. Then, the fixing rods 202 are vertically inserted into the adjustment holes 103 around the placement area 102 using the anti-slip pads 203 attached to the lower surface. At the same time, the sliding adjustment of the restraint strap 201 on the upper surface of the fixing rods 202 is adjusted to effectively fix the rat's body and ensure the fixation of the rat's head and neck.

[0034] Then, according to the shooting needs, the relevant labels or recording information can be written on the surface of the label card 3 and horizontally inserted into the inside of the insertion frame 104 to assist in subsequent shooting. When the fill light 4 is needed, the stabilizer 401 is inserted into the docking slot 105 and the entire fill light 4 is connected and fixed to the fixed platform 1 with bolts. Then, the flexible support rod 402 can be bent and adjusted to adjust the orientation of the lamp head 403 appropriately, thereby providing good lighting assistance to the surface of the fixed platform 1 to meet different work needs.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
