Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medical equipment in a medical radiation environment, and in particular to a manual injection bracket for auxiliary radiation equipment. Background Art
[0002] In modern hospitals, the pain department is a newly emerging clinical department in recent years. It mainly treats some chronic pain syndromes, neuropathic pain, cancer pain, musculoskeletal pain and other pain symptoms. It often uses minimally invasive interventional treatments and has achieved good results in the field of intractable pain that cannot be relieved by many external and internal medications and physical therapy, allowing patients to get rid of the side effects and toxic effects of long-term drug therapy and physical therapy.
[0003] Most patients suffer from trauma and degenerative bone hyperplasia in the spine and cervical spine, which compress the nerves and cause long-term pain. Minimally invasive interventional treatment mainly treats pain by injecting drugs into the lesions, and through anti-inflammatory, dehydration, swelling, analgesic and other treatment methods. When injecting drugs into the bone gaps of the spine and cervical spine, a CT machine is required for radiation irradiation to assist in precise positioning so that the liquid in the needle can be injected directly into the lesion.
[0004] However, in reality, it is impossible for doctors to position the needle by exposing it to CT radiation. They can only conduct experiments by going back and forth between the control room and the operating bed. In view of this, how to achieve accurate positioning of the needle to the lesion in a radiation environment while reducing the risk of radiation damage to medical staff has become an urgent problem that technicians in this field need to solve.

[0019] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.
[0020] Figure 1 and Figure 2 The structure of the manual injection support 100 for auxiliary radiation equipment according to an embodiment of the present invention is shown together.

[0021] When the manual injection support 100 for auxiliary radiation equipment of the embodiment of the present invention is in use, the support base plate 1 can be installed in the slideway at the edge of the operating bed through a pulley, and locked beside the operating bed by a positioning bolt after the sliding position is in place; by adjusting the rotation and positioning of the horizontal rotating shaft 2 relative to the support base plate 1, the position of the retractable fixed beam 4 on the horizontal plane can be adjusted, and by adjusting the extension and retraction of the retractable fixed beam 4, it can be retracted to the patient's injection area and then locked and opened by the locking bolt 41; by adjusting the rotation and positioning of the retractable fixed beam 4 relative to the vertical column 3, the position of the retractable fixed beam 4 on the vertical plane perpendicular to the horizontal plane can be adjusted; by adjusting the needle adjustment assembly 5 connected to the free end of the retractable fixed beam 4, the spherical rotating shaft 52 is rotated and positioned in the shaft sleeve 51, and the deflection angle of the syringe 54 fixedly connected to the spherical rotating shaft 52 can be adjusted, so as to finally adjust the alignment position of the syringe 54.
[0022] The manual injection stand 100 for assisting radiation equipment according to the embodiment of the present invention can accurately align the needle of the syringe 54 with the injectable position of the lesion based on the regional position of the lesion given by the radiation equipment (such as CT) and the doctor's experience, which avoids the doctor holding the syringe and exposing it to the CT radiation to manually position the needle tube, and does not need to go back and forth between the control room and the operating bed for many times to conduct experimental exploration, thereby achieving the precise positioning of the lesion by the needle tube in the radiation environment while reducing the risk of radiation injury to medical staff. The manual injection stand 100 for assisting radiation equipment according to the embodiment of the present invention can be used in radioactive environments such as hospital pain departments and places where human individuals cannot stay for a long time, but at the same time require diagnosis and surgery.
[0023] According to the present invention, in Figure 2 In the preferred embodiment shown, a medical silicone 53 is provided between the shaft sleeve 51 and the spherical shaft 52. The medical silicone 53 plays the role of making the spherical shaft 52 rotate smoothly, increasing damping, and positioning away from the hand. The medical silicone 53 is a high-strength medical silicone, which can provide sufficient damping to maintain the position of the spherical shaft 52. Further, medical silicone can also be provided between the through hole 55 and the syringe 54. The medical silicone can be a high-strength medical silicone sleeve, which can provide sufficient damping to fix the syringe 54.
[0024] It should be noted that during the application process, the damping performance of the high-strength medical silicone needs to be examined, and disinfection work should be done to ensure the accuracy of the positioning of the syringe 54 and avoid the occurrence of infection problems.
[0025] According to the present invention, in Figure 1 In the preferred embodiment shown, a first positioning assembly may be provided on the horizontal rotation shaft 2, and the first positioning assembly may include a transverse support arm 61 connected to the horizontal rotation shaft 2 and a first positioning bolt 62 (preferably made of stainless steel 304) vertically connected to the transverse support arm 61, and the first positioning bolt 62 is used to lock with the bracket bottom plate 1 to achieve positioning of the horizontal rotation shaft 2. In this embodiment, when the horizontal rotation shaft 2 needs to be rotated, the first positioning bolt 62 can be adjusted to be separated from the bracket bottom plate 1, and when the horizontal rotation shaft 2 needs to be positioned and rotated, the first positioning bolt 62 can be rotated to be pressed against the bracket bottom plate 1, and the setting of the first positioning assembly achieves rapid positioning of the horizontal rotation shaft 2 with a simple structure.
[0026] Furthermore, if Figure 1As shown, the support base plate 1 may also be formed with a first limiting rod 63 and a second limiting rod 64 located on both sides of the horizontal rotation axis 2, and the lateral support arm 61 can move within a first range defined by the first limiting rod 63 and the second limiting rod 64. Preferably, the first range may be configured such that the rotation angle range of the horizontal rotation axis 2 is 0° to 180°. In this embodiment, the provision of the first limiting rod 63 and the second limiting rod 64 enables the limitation of the rotation range of the horizontal rotation axis 2, and can prevent the horizontal rotation axis 2 from being rotated unrestrictedly at a large angle that may occur when the first positioning assembly is unstable during use, thereby helping to improve the safety of the manual injection support 100 for auxiliary radiation equipment during use.
[0027] In such Figure 1 In the preferred embodiment shown, a second positioning bolt 71 (preferably made of stainless steel 304) may be provided on the vertical column 3, and the second positioning bolt 71 is used to lock with the telescopic fixed beam 4 to achieve positioning of the telescopic fixed beam 4. In this embodiment, when the telescopic fixed beam 4 needs to be rotated, the second positioning bolt 71 can be adjusted to be separated from the telescopic fixed beam 4, and when the telescopic fixed beam 4 needs to be positioned, the second positioning bolt 71 can be rotated to be pressed against the telescopic fixed beam 4. The second positioning bolt 71 is provided to achieve rapid positioning of the telescopic fixed beam 4 with a simpler structure.
[0028] Furthermore, if Figure 1 As shown, a limit block 72 may be provided on the lower surface of the telescopic fixed beam 4 or the area of the vertical column 3 opposite to the lower surface of the telescopic fixed beam 4. The setting of the limit block 72 can prevent the telescopic fixed beam 4 from rotating without limit at a large angle due to unstable positioning of the second positioning bolt 71 during use, thereby helping to further improve the safety of the manual injection support 100 for auxiliary radiation equipment during use.
[0029] In such Figure 1In the preferred embodiment shown, a third limiting rod assembly may also be provided at the top of the vertical column 3, and the third limiting rod assembly may include a vertical rod 73 connected to the vertical column 3 and a horizontal rod 74 vertically connected to the vertical rod 73, the axial direction of the horizontal rod 74 is perpendicular to the axial direction of the horizontal rotation axis 2, and the telescopic fixed beam 4 can move within a second range defined by the limiting block 72 and the horizontal rod 74. Preferably, the second range is configured so that the rotation angle range of the telescopic fixed beam is 0° to 150°. In this embodiment, the setting of the limiting block 72 and the horizontal rod 74 realizes the limitation of the rotation range of the telescopic fixed beam 4, which can further prevent the telescopic fixed beam 4 from rotating at a large angle that may occur when the positioning of the second positioning bolt 71 is unstable during use, thereby helping to further improve the safety of the manual injection support 100 for auxiliary radiation equipment during use.
[0030] According to the present invention, in Figure 2 In the preferred embodiment shown, the sleeve 51 can be a stainless steel sleeve, the spherical shaft 52 can be a 316 medical stainless steel spherical shaft, and the sleeve 51 can be opened and locked by bolts 56 (preferably 304 stainless steel bolts) to facilitate the installation and removal of the spherical shaft 52 and the medical silicone 53 in the sleeve 51. Preferably, the spherical shaft 52 can rotate freely in the sleeve 51, and the rotatable angle is preferably 150 degrees.
