Description

Technical Field

[0001] The utility model relates to the technical field of limb fixation, in particular to a limb fixation frame. Background Art

[0002] During surgeries in departments such as gynecology and urology, in order to support the patient's feet and obtain a larger surgical field, a foot support is usually installed on the operating table to fix the position of the patient's lower limbs so that medical staff can perform the operation better.

[0003] At present, the existing foot support for operating tables is composed of components such as an arc plate, a support rod and Velcro. In actual use, the patient directly places the lower limbs on the arc plate, and then the medical staff uses Velcro to fix the lower limbs. However, with the increase in the number of uses, the hook surface of the Velcro will become straight, and the hair surface will become uncurled, so that it will not stick, while the arc plate is still intact. Since the Velcro and the arc plate are fixedly connected, in order to ensure the fixation effect of the limbs, the entire foot support needs to be discarded and replaced, which will increase the use cost of the device. For this reason, we propose a limb fixation frame to solve the above problem. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and provides a limb fixing frame.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-5 A limb fixation frame comprises an operating bed 1, support rods 2 are symmetrically distributed on the sides of the operating bed 1, and an arc-shaped plate 3 is provided at the top of the support rod 2. The connection method between the operating bed 1 and the support rod 2 is the prior art and will not be described in detail here. The top of the arc-shaped plate 3 is covered with a fixing belt 4, and the side of the arc-shaped plate 3 is connected to a fixing block 5, and a receiving groove 6 is opened inside the fixing block 5, and a moving block 7 is engaged with the inside of the receiving groove 6, and one end of the moving block 7 is connected to a limiting block 8, and a card slot adapted to the limiting block 8 is opened equidistantly inside the fixing belt 4, and the other end of the moving block 7 is connected to a pulling block 10 through a connecting rod 9.

[0024] Further, see Figure 2 and Figure 4 It can be known that the bottom end of the arc plate 3 is connected to a threaded sleeve 13, and the top end of the support rod 2 is provided with an external thread that matches the threaded sleeve 13. Through the threaded cooperation of the arc plate 3 and the support rod 2, the staff can quickly replace the damaged arc plate 3.

[0025] Further, see Figure 1 and Figure 2 It can be known that there are two groups of fixing blocks 5, and the two groups of fixing blocks 5 are symmetrically distributed about the central axis of the arc plate 3. Since two groups of fixing blocks 5 are provided on the outer side of the arc plate 3, the locking and limiting of the two ends of the fixing belt 4 can be achieved. Therefore, when the fixing belt 4 is damaged after long-term use, the staff can quickly remove the fixing belt 4 from the upper side of the arc plate 3 for replacement.

[0026] Further, see Figure 2 and Figure 4 It can be known that a rubber pad 14 is glued to the upper surface of the arc plate 3, and anti-slip grooves are evenly arranged on the upper side of the rubber pad 14. The rubber pad 14 made of rubber material can effectively improve the comfort of the patient during placement, so as to effectively prevent the patient's lower limbs from being crushed, and the opening of the anti-slip grooves can effectively improve the limiting effect on the patient's lower limbs.

[0027] Further, see Figure 3 It can be known that the inner wall of the accommodating groove 6 is connected with a spring 11, and the other end of the spring 11 is fixedly connected to the moving block 7. The spring 11 connected between the accommodating groove 6 and the moving block 7 can effectively improve the tightness of the limit block 8 when it is engaged in the internal slot of the fixing belt 4, which can effectively prevent the limit block 8 from moving easily during the engagement process.

[0028] Further, see Figure 3 It can be known that the ends of the moving block 7 are symmetrically provided with insertion grooves, and guide rods 12 are inserted inside the insertion grooves. The ends of the guide rods 12 are fixedly connected to the inner wall of the accommodating groove 6. When in use, the moving block 7 can be guided by the guide rods 12 and the insertion grooves provided inside the moving block 7, thereby preventing the stability of the limit block 8 during the movement process.

[0029] Further, see Figure 2 , Figure 4 and Figure 5 It can be known that docking grooves compatible with the fixing block 5 are provided at both ends of the curved plate 3, a threaded rod 15 is vertically inserted inside the fixing block 5, and a rotating block 16 is connected to the top of the threaded rod 15, and a positioning groove compatible with the threaded rod 15 is provided inside the curved plate 3. When the spring 11 is deformed after long-term use, it is difficult for the limit block 8 to limit the fixing belt 4. At this time, the staff can rotate the rotating block 16, so that the threaded rod 15 and the internal thread in the positioning groove can be threadedly matched to pull the threaded rod 15 out of the interior of the curved plate 3. At this time, the limit of the fixing block 5 can be released, thereby realizing the disassembly of the damaged fixing block 5, so that the damaged fixing block 5 does not need to be discarded together with the curved plate 3, which can further save the use cost of the device.

[0030] Working principle: When the utility model is in use, the patient can first lie flat on the operating table 1 and place the lower limbs on the arc plate 3. Then the medical staff can pull the pulling block 10 in sequence, so that the connecting rod 9 and the movable block 7 can drive the limit block 8 to move, so as to pull the limit block 8 out from the inside of the fixing belt 4. At this time, the staff can pull the fixing belt 4 and abut it against the patient's limbs. When the fixing belt 4 is pulled to the appropriate position, the staff can stop pulling the pulling block 10, so that the limit block 8 is again engaged with another set of slots opened inside the fixing belt 4, so that the patient's lower limbs can be fixed. The above is the entire working principle of the utility model.

[0031] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

[0032] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
