Description

Technical Field

[0001] This utility model relates to the field of molybdenum target positioning seats, and in particular to an adjustment mechanism and a molybdenum target positioning seat. Background Technology

[0002] The existing mammography positioning chair requires patients to sit with their backs straight, which can easily put them in a state of high tension. Maintaining this position for a long time can cause patients to move involuntarily, resulting in a decrease in the pressure of the compression plate, affecting the positioning process and accuracy. Therefore, the existing chair has certain defects in use.

[0003] The chair lacks a platform for placing anesthetics and disinfection dressings needed by doctors. Doctors have to walk a few steps to the table to retrieve and store these items when needed, which prolongs the positioning time to some extent.

[0004] Existing mammography puncture positioning chairs cannot assist patients in leaving the examination gantry. Patients need to stand up before the puncture needle is fully bandaged, which poses a challenge for weakened patients who have just completed the positioning procedure. Chairs with three-wheeled casters on the market are prone to movement, causing patients to unconsciously shift during prolonged positioning, leading to inaccurate positioning. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to solve the problems of patients being easily highly nervous, having difficulty standing, and having difficulty picking up items when using a molybdenum target puncture positioning chair during puncture positioning.

[0010] In a preferred embodiment of the adjustment mechanism of the present invention: the first lateral adjustment member includes a first sleeve portion and a second sleeve portion that are sleeved on each other, and one end of the first sleeve portion is sleeved on the operating rod.

[0011] In a preferred embodiment of the adjustment mechanism of the present invention: a limit hole is provided at one end of the angle adjustment rod, and a second locking switch is rotatably connected and movable in the limit hole.

[0012] In a preferred embodiment of the adjustment mechanism of the present invention: a first through hole is provided on the first sleeve part, and limit plates are fixedly connected to both sides of the first through hole. A rotating rod is rotatably connected between the two limit plates, and a first locking switch is fixedly connected to the rotating rod.

[0013] In a preferred embodiment of the adjustment mechanism of the present invention: the second lateral adjustment member includes a lever, the end of which is provided with a curved portion.

[0014] In a preferred embodiment of the adjustment mechanism of the present invention: the second locking switch is eccentrically connected to the limiting hole, and the first locking switch is eccentrically connected to the rotating rod.

[0015] In a preferred embodiment of the adjusting mechanism described in this invention, it further includes:

[0016] The longitudinal adjustment component includes a threaded hole formed in the side wall of the first sleeve portion, and a locking bolt is threadedly connected to the threaded hole.

[0017] In a preferred embodiment of the adjustment mechanism of the present invention: a push rod is fixedly connected to one end of the operating rod, the push rod is T-shaped, and an operating platform and a trash can are fixedly connected to the operating rod.

[0018] The beneficial effects of this invention are as follows: It achieves precise adjustment of the chair back angle, lateral distance, and longitudinal height through multi-dimensional adjustment, adapting to the needs of patients of different heights.

[0031] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0032] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0033] Reference Figure 1 This embodiment provides an adjustment mechanism and a molybdenum target positioning seat, including a seat 5, a backrest 3, and an adjustment mechanism for adjusting the relative position of the seat 5 and the backrest 3, including an angle adjustment component 2 connected to the backrest 6; and a lateral adjustment component 1, including a first lateral adjustment member 11 and a second lateral adjustment member 12, wherein: the first lateral adjustment member 11 is connected to the angle adjustment component 2; and the second lateral adjustment member 12 is installed on the seat 5.

[0034] Furthermore, the longitudinal adjustment component 3 is installed on one side of the first lateral adjustment component 11.

[0035] Specifically, the operating lever 4 is equipped with a horizontal adjustment component 1 and a vertical adjustment component 3; wherein, the angle adjustment component 2 and the horizontal adjustment component 1 form an adjustable angle; the vertical adjustment component 3 can move along the vertical direction of the operating lever 4; and the horizontal adjustment component 1 can extend and retract along the horizontal direction of the operating lever 4.

[0036] Furthermore, armrests 7 are installed on both sides of the seat 5, a support 8 and casters 9 are installed at the bottom of the seat 5, and a foot pedal 81 is fixedly connected to the support 8.

[0037] The chair back 6 supports the patient's lower back, keeping it straight and facilitating puncture.

[0038] The bracket 8 connects the pulley 9 to the seat 5, the bracket 8 supports the seat, the pulley 9 facilitates the movement of the seat, and the design of the two armrests 7 provides support for the patient to stand up on their own after the puncture.

[0039] The angle of the chair back 6 can be adjusted by adjusting the angle adjustment component 2 on the horizontal adjustment component 1, so as to provide appropriate back support for patients of different heights.

[0040] The lateral adjustment component includes a first lateral adjustment component 11, which is connected to one side of the angle adjustment component. The first lateral adjustment component 11 can be extended and retracted to adjust the distance between the chair back 6 and the operating lever 4, making it suitable for patients of different heights.

[0041] The height of the chair back 6 is adjusted by moving the longitudinal adjustment component on the operating lever 4 via the first lateral adjustment component 11. The longitudinal adjustment component works together with the first lateral adjustment component 11 to provide appropriate back support for patients of different heights.

[0042] The lateral adjustment component also includes a second lateral adjustment component 12. One end of the second lateral adjustment component 12 is fixed to the operating rod 4, and the other end is fixed to the chair seat 5. The distance between the chair seat 5 and the operating rod 4 can be adjusted by extending and retracting the second lateral adjustment component 12. The adjustment together with the chair seat 5 facilitates the mammography puncture operation on the patient.

[0043] Reference Figure 1 In some embodiments, a push rod 41 is fixedly connected to one end of the operating lever 4. The push rod 41 is T-shaped, and an operating platform 42 and a trash can 43 are fixedly connected to the operating lever 4.

[0044] The push rod 41 at the top of the control lever 4 is used to push the seat and move it to the desired position. The horizontal section of the T-shaped structure provides a larger contact area for force application, allowing the operator's palm to fit naturally and reducing fatigue during pushing. Compared with the traditional straight lever design, the T-shaped structure allows the operator to apply force at a more flexible angle, especially when adjusting the seat direction or moving it, reducing the twisting motion of the arm and wrist, which is ergonomic. The lateral extension of the T-shaped structure can also serve as a stabilizing fulcrum, preventing the control lever 4 from shifting due to lateral forces during pushing.

[0045] Meanwhile, the push rod 41 and the operating rod 4 are designed with an inclined angle so that when medical staff push the seat, their arms and torso form a natural angle, reducing operational fatigue. Compared with the traditional straight rod design, the T-shaped structure provides a larger force application contact area, reducing the risk of slippage caused by single-point force. The operating platform 42 is located on the upper part of the operating rod 4 and is used to place the anesthetic and disinfection bandages needed by the doctor. The trash can 43 is installed at the bottom of the operating rod 4 and is used to place medical waste.

[0046] Reference Figure 2 and Figure 3 In some embodiments, the first lateral adjustment member 11 includes a first sleeve portion 111 and a second sleeve portion 112 that are sleeved on each other, and one end of the first sleeve portion 111 is sleeved on the operating lever 4.

[0047] Furthermore, a first through hole 113 is provided on the first fitting part 111, and limit plates 114 are fixedly connected to both sides of the first through hole 113. A rotating rod 115 is rotatably connected between the two limit plates 114, and a first locking switch 116 is fixedly connected to the rotating rod 115. The first locking switch 116 is eccentrically connected to the rotating rod 115.

[0048] The interlocking of the first sleeve portion 111 and the second sleeve portion 112 allows for adjustment of their overall length. Simultaneously, a first through hole 113 is formed on the first sleeve portion 111, allowing the second sleeve portion 112 to be directly exposed, facilitating observation of the overlap between the first sleeve portion 111 and the second sleeve portion 112 and preventing them from detaching. Furthermore, the first through hole 113 facilitates the locking of the second sleeve portion 112 by the first locking switch 116, thus fixing the relative positions of the first sleeve portion 111 and the second sleeve portion 112.

[0049] The first locking switch 116 is installed on the first sleeve part 111 via the limiting plate 114. The rotating rod 115 is fixedly connected to the first locking switch 116. The connection point between the rotating rod 115 and the first locking switch 116 is off-center from the rotation axis. When the first locking switch 116 rotates, its end will generate radial displacement. The end of the first locking switch 116 and the second sleeve part 112 are pressed against each other to counteract the sliding friction between the sleeve parts and ensure locking reliability.

[0050] Reference Figure 2 and Figure 5 In some embodiments, the second lateral adjustment member 12 includes a lever 121, the end of which is provided with a curved portion.

[0051] The second lateral adjustment member 12 has the same structure as the first lateral adjustment member 11, both using a sleeve structure to achieve length adjustment. The first locking switch 116 of the first lateral adjustment member 11 is equivalent to the toggle lever 121 of the second lateral adjustment member 12. The toggle lever 121 is longer than the first locking switch 116, and the extended part forms a larger operating lever arm. When applying the same torque, the required force is smaller. At the same time, the toggle lever 121 is toggle vertically. The vertical toggle direction reduces the interference of the trash can 43 during operation. The curved part at the end of the toggle lever 121 matches the natural bending angle of human fingers, providing a more stable grip and facilitating the locking and unlocking of the second lateral adjustment member 12.

[0052] Reference Figure 2 and Figure 4 In some embodiments, the angle adjustment component 2 includes a support block 21 fixedly connected to one end of the second sleeve part 112, an angle adjustment rod 22 installed in the hole of the support block 21, a limit hole 221 opened at one end of the angle adjustment rod 22, a second locking switch 23 rotatably connected in the limit hole 221, and an angle connecting block 24 fixedly connected to the angle adjustment rod 22, and the angle connecting block 24 is fixed to the backrest 6.

[0053] Furthermore, the second locking switch 23 is eccentrically connected to the limiting hole 221.

[0054] The support block 21 is provided in two parts, and the support block 21 is U-shaped. Each U-shaped support block 21 has a circular hole on its parallel surface. An angle adjustment rod 22 is rotatably connected in the four circular holes. The angle adjustment rod 22 rotates in the circular holes but cannot move horizontally in the circular holes. A second locking switch 23 is rotatably connected in the limiting hole 221. A limiting rod is installed at one end of the second locking switch 23. The limiting rod rotates in the limiting hole 221. The connection point between the limiting rod and the second locking switch 23 is off the axis of rotation. When the second locking switch 23 rotates, its end will generate radial displacement. The end of the second locking switch 23 and the support block 21 are pressed against each other to ensure the reliability of locking.

[0055] Reference Figure 2 and Figure 7 In some embodiments, the longitudinal adjustment component 3 includes a threaded hole 31 opened in the side wall of the first sleeve 111, and the threaded hole 31 is threadedly connected to a locking bolt 32.

[0056] The locking bolt 32 rotates within the threaded hole 31 and abuts against the operating rod 4, fixing the first lateral adjustment member 11 to the operating rod 4.

[0057] Reference Figure 6 In some embodiments, locking elements 91 are installed on the two pulleys 9.

[0058] Since the seat 5 and the bracket 8 cannot rotate, the two pulleys 9 with locking elements 91 are always located behind the seat.

[0059] Furthermore, the locking component 91 includes a support piece 913 fixedly connected to the bracket 8, a locking rod 911 fixedly connected to the support piece 913, a third locking switch 912 rotatably connected to the locking rod 911, and the third locking switch 912 being eccentrically connected to the locking rod 911.

[0060] The support plate 913 adopts a convex structure, and the locking rod 911 is fixed to the center of the support plate 913 by threads. Its end is eccentrically connected to the third locking switch 912. This eccentric structure causes the end of the third locking switch 912 to generate radial displacement when it rotates, thereby generating a greater locking force. When the third locking switch 912 rotates to the locked position, its end presses against the outer edge of the pulley 9 through the eccentric structure, locking the pulley 9 and thus locking the seat.

[0061] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
