Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to an orthopedic perspective auxiliary device. Background Art
[0002] In orthopedic surgery, especially in trauma orthopedic surgery, the affected limb is often required to be fixed and C-arm fluoroscopy is performed. In some cases, joint stress position examination is also required. In the current situation, medical staff need to manually fix the affected limb at the stress position for fluoroscopy, which exposes the medical staff to radiation and is not conducive to their health.
[0003] Among the fluoroscopic equipment in the imaging department, some metal baffles can be used for stress position fluoroscopy of the affected limb, but this cannot be used in sterile surgery. In orthopedic sterile surgery, there are requirements for the material and fluoroscopy of the equipment. It needs to have sufficient strength and hardness, and it needs to be able to pass the existing instrument disinfection technology requirements. The material needs to be able to pass through X-rays without developing, so as not to affect the judgment of bone position during surgery.
[0004] In the prior art, some medical institutions have auxiliary devices for limiting the patient's body position, posture or limbs during surgery. Such auxiliary devices generally include a plate-like structure and multiple limiting rods. The plate-like structure is provided with multiple holes, and the multiple limiting rods are inserted into different holes. The patient's limbs are then placed on the plate-like structure, and the patient's limbs are limited by the multiple limiting rods to facilitate the operation.
[0005] However, the hole of the auxiliary device in the prior art is fixed, which results in that during actual use of the auxiliary device, the limiting rod thereof cannot be in good contact with the patient's limb, resulting in a failure to properly limit the patient's limb. Utility Model Content
[0006] The technical problem to be solved by the utility model is to provide an orthopedic fluoroscopic auxiliary device to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.
[0007] The solution of the utility model to solve the technical problem is:
[0008] Orthopedic fluoroscopic auxiliary device, including:
[0009] A panel, wherein the panel is provided with a plurality of strip holes, and the plurality of strip holes are parallel to each other;
[0010] A bottom plate, wherein a clamping space is formed between the bottom plate and the panel;
[0011] A tension adjustment structure, the tension adjustment structure is arranged between the panel and the bottom plate, and the tension adjustment structure is used to adjust the height of the clamping space;
[0012] An adjustable chassis is arranged in the clamping space, the two end surfaces of the adjustable chassis are respectively in contact with the panel and the bottom plate, the number and position of the adjustable chassis and the strip holes are arranged one by one; the width of the adjustable chassis is greater than the width of the strip holes;
[0013] A limiting rod is connected to the adjusting chassis, the limiting rod passes through the clamping space from the strip hole, and the width of the limiting rod is smaller than the width of the strip hole.
[0014] Through the above technical solution, the medical staff first places the patient's limb on the panel, and then one person puts the affected limb into the required posture, and the other person operates the limit rod to adjust the position of the limit rod. Compared with the limit rod of the prior art, the limit rod of this solution has a certain range of motion, which can make the limit rod better fit the patient's limb, and there is no need to align the limit rod with the hole position and then insert it, and there is no need to lose the stress position requirement of the affected limb in order to accommodate the hole position. The position adjustment of the limit rod is relatively simple.
[0015] When all the limit rods are adjusted, the medical staff rotates the tension adjustment structure to adjust the distance between the bottom plate and the panel, so that the bottom plate and the panel clamp the adjustment chassis, thereby fixing the adjustment chassis and fixing the position of the limit rods.
[0016] As a further improvement of the above technical solution, the tension adjustment structure is a screw, the head of the tension adjustment structure abuts against the panel, and the tension adjustment structure is threadedly connected to the base plate.
[0017] As a further improvement of the above technical solution, it also includes a plurality of supporting structures, the thickness of the supporting structures is the same as the thickness of the adjusting chassis, and the supporting structures are arranged in the clamping space.
[0018] Through the above technical solution, when the tension adjustment structure drives the base plate and the panel to be close together, the base plate and the panel will contact the supporting structure. By setting the supporting structure, compared with only setting the adjustment base plate between the base plate and the panel, serious local deformation can be avoided, thereby effectively avoiding the situation where the adjustment chassis cannot be effectively clamped, to ensure that the limit rod does not move when limiting, and to achieve the goal of keeping the limb in the stress position for perspective, thereby ensuring the smooth progress of the operation and making the judgment of fracture reduction more accurate.
[0019] As a further improvement of the above technical solution, the limiting rod is detachably connected to the adjusting chassis.
[0020] Through the above technical solution, the limit rod is set to be detachably connected to the adjustment chassis, so that medical staff can choose whether to install the limit rod, thereby avoiding the redundant limit rod from hindering the operation. Moreover, the limit can be implemented by adjustment for the limbs of patients with different sizes.
[0021] As a further improvement of the above technical solution, the limiting rod is detachably connected to the adjusting chassis via a threaded structure.
[0022] Through the above technical solution, by arranging the limit rod and the adjusting chassis in a threaded connection form, the installation of the limit rod is more convenient.
[0023] As a further improvement of the above technical solution, the limit rod is inserted into the adjusting chassis, and a positioning structure is provided between the limit rod and the adjusting chassis. The positioning structure includes a positioning hole and a positioning pin. The number of the positioning holes is two, and the two positioning holes are respectively arranged on the limit rod and the adjusting chassis. The positioning hole is inclined relative to the central axis of the limit rod, and the positioning pin is inserted into the two positioning holes.
[0024] As a further improvement of the above technical solution, a connecting rope is provided between the positioning pin and the limiting rod.
[0025] Through the above technical solution, by providing a connecting rope, the positioning pin can be prevented from being lost, thereby preventing the loss of the positioning pin from affecting the normal use of the orthopedic fluoroscopy auxiliary device.
[0026] As a further improvement of the above technical solution, the side wall of the limit rod includes a plurality of arcuate surfaces, which are arranged in a circular array around the central axis of the limit rod, and the central axis of the arcuate surface is eccentrically arranged with respect to the central axis of the limit rod.
[0027] Through the above technical solution, the curved surface can better fit the patient's limbs.
[0028] As a further improvement of the above technical solution, the radii of the multiple arc-shaped surfaces of the same limiting rod are different.
[0029] Through the above technical solution, through such a setting, medical staff can select the corresponding curved surface to contact the patient's limb according to the arc of the patient's limb, so that the limit rod can better fit the patient's limb, and will not cause long-term use of the device to cause pressure on the limbs, especially on the shallow skin.
[0030] As a further improvement of the above technical solution, two adjacent arc-shaped surfaces are transitioned by a round chamfer.
[0031] Through the above technical solution, a round chamfer is set between two adjacent arc-shaped surfaces, which can reduce the edges and corners of the limiting rod, thereby preventing the patient's limbs from being damaged due to the edges and corners or feeling uncomfortable after surgery due to long-term compression of the edges and corners.
[0032] The beneficial effects of the utility model are: during orthopedic surgery, the affected limb is fixed, and a fluoroscopic device is provided for medical staff, so that special orthopedic positions, such as ankle joint stress position, calcaneal axis position, etc., can be seen during the fluoroscopic operation. Therefore, it is not necessary to fix it manually as before, which would expose it to radiation too much. Moreover, due to the special material of the device, the quality of the fluoroscopic view is guaranteed, and no artifacts will appear. On the other hand, the special design of the limit rod of the device can make the limit rod better fit the patient's limb, and the position adjustment of the limit rod is relatively simple, and no iatrogenic damage will be caused to the patient's limb. The detachable design of the limit rod avoids the influence of the limit rod on the operation, and can be adjusted according to the size and length of the patient's limb, which is suitable for most traumatic orthopedic surgeries.
[0033] The utility model is used in the technical field of medical equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Reference Figures 1 to 3 The orthopedic perspective auxiliary device is provided with a first direction and a second direction, and comprises a panel 100, a bottom plate 200, a tension adjustment structure 300, an adjustment chassis 400 and a limit rod 500.
[0044] The upper end of the panel 100 is provided with a placement area.
[0045] Specifically, the panel 100 is a rectangular plate-shaped member, the length direction of the panel 100 is arranged parallel to the first direction, the width direction of the panel 100 is arranged parallel to the second direction, and the panel 100 is provided with strip holes 110, the number of the strip holes 110 is set to be multiple, and the multiple strip holes 110 are all arranged parallel to the first direction. The multiple strip holes 110 are divided into two groups, and the two groups of strip holes 110 are respectively arranged on both sides of the placement area in the first direction.
[0046] Specifically, in this embodiment, the number of the strip holes 110 is set to six. In other embodiments, the number of the strip holes 110 may also be set to four, eight, etc. Those skilled in the art may select the number of the strip holes 110 according to actual needs.

[0048] A clamping space is formed between the bottom plate 200 and the panel 100 .
[0049] The tension adjustment structure 300 is arranged between the bottom plate 200 and the panel 100, and the tension adjustment structure 300 is used to adjust the height of the clamping space. Specifically, in the present embodiment, the tension adjustment structure 300 is arranged as a screw, the head of the tension adjustment structure 300 abuts against the panel 100, and the threaded portion of the tension adjustment structure 300 is threadedly connected to the bottom plate 200. In other embodiments, the tension adjustment structure 300 may also be arranged as a scheme in which the head abuts against the bottom plate 200 and the threaded portion is threadedly connected to the panel 100, and those skilled in the art may select the specific connection scheme of the tension adjustment structure 300 according to actual needs.
[0050] The adjusting chassis 400 is arranged in the clamping space, and the adjusting chassis 400 is movably connected with the bottom plate 200 and the panel 100. The number of the adjusting chassis 400 is consistent with the number of the strip holes 110, and the adjusting chassis 400 and the strip holes 110 are arranged one by one. The upper and lower end surfaces of the adjusting chassis 400 are respectively in contact with the bottom plate 200 and the panel 100. The adjusting chassis 400 is arranged in a disc-shaped structure so that the adjusting chassis 400 can rotate and slide relatively freely in the clamping space. The diameter of the adjusting chassis 400 is greater than the width of the strip holes 110, so that the adjusting chassis 400 will not escape from the clamping space through the strip holes 110.
[0051] The limiting rod 500 is connected to the adjusting chassis 400 , and the limiting rod 500 passes through the clamping space from the strip hole 110 .
[0052] Specifically, the limiting rod 500 is detachably connected to the adjusting chassis 400, and the limiting rod 500 is arranged to be detachably connected to the adjusting chassis 400 so that medical staff can choose whether to install the limiting rod 500, thereby avoiding redundant limiting rods 500 from obstructing the operation.
[0053] Specifically, in the present embodiment, the limiting rod 500 is detachably connected to the adjusting chassis 400 via a threaded structure. By arranging the limiting rod 500 and the adjusting chassis 400 in a threaded connection, the installation of the limiting rod 500 is more convenient.
[0054] Specifically, the width of the limiting rod 500 is smaller than the width of the strip hole 110, so that the limiting rod 500 can additionally have the freedom to slide in the second direction relative to the panel 100, that is, the limiting rod 500 can slide in the first direction and the second direction, so that the adjustment range of the limiting rod 500 is increased, so that the limiting rod 500 can better limit the patient's limbs.
[0055] Specifically, in this embodiment, the side wall of the limiting rod 500 is composed of a plurality of arcuate surfaces 510. Specifically, in this embodiment, the side wall of the limiting rod 500 is composed of three arcuate surfaces 510, the circumferential axes of the three arcuate surfaces 510 are all eccentrically arranged with respect to the central axis of the limiting rod 500, and the three arcuate surfaces 510 are arranged in a circumferential array around the central axis of the limiting rod 500. The arcuate surfaces 510 can better fit the patient's limbs.
[0056] Specifically, a round chamfer is provided between two adjacent arc-shaped surfaces 510 for transition, and the round chamfer is provided between two adjacent arc-shaped surfaces 510 to reduce the edges and corners of the limiting rod 500, thereby preventing the patient's limbs from being damaged due to the edges and corners or feeling discomfort after surgery due to prolonged compression of the edges and corners.
[0057] Specifically, in this embodiment, the radii of the multiple curved surfaces 510 of the limiting rod 500 are different. Through such a setting, medical staff can select the corresponding curved surface 510 to contact the patient's limb according to the arc of the patient's limb, so that the limiting rod 500 can better fit the patient's limb.
[0058] Specifically, in this embodiment, the orthopedic fluoroscopy auxiliary device also includes a supporting structure 600, and the number of the supporting structures 600 is set to be multiple, and the multiple supporting structures 600 are evenly arranged in the clamping space. The thickness of the adjusting chassis 400 is the same as the thickness of the supporting structure 600. When the tension adjustment structure 300 drives the base plate 200 and the panel 100 to approach, the base plate 200 and the panel 100 will contact the supporting structure 600. By setting the supporting structure 600, compared with only setting the adjusting base plate 200 between the base plate 200 and the panel 100, severe local deformation can be avoided, thereby effectively avoiding the situation where the adjusting chassis 400 cannot be effectively clamped, so as to ensure that the limit rod 500 does not move when limiting, thereby ensuring the smooth progress of the operation.
[0059] The medical staff first places the patient's limb on the panel 100, and then one person assumes the required posture, and the other person operates the limit rod 500 to adjust the position of the limit rod 500, so that the limit rod 500 can better fit the patient's limb. The position adjustment of the limit rod 500 of this solution is relatively simple, and there is no need to align the limit rod 500 with the hole and then insert it.
[0060] When all the limit rods 500 are adjusted, the medical staff rotates the tension adjustment structure 300 to adjust the distance between the bottom plate 200 and the panel 100. Thus, the bottom plate 200 and the panel 100 clamp the adjustment chassis 400, thereby fixing the adjustment chassis 400 and fixing the position of the limit rods 500. Example
[0061] Reference Figure 4 Different from the first embodiment, in this embodiment, the lower end of the limiting rod 500 is inserted into the adjusting chassis 400 , and the limiting rod 500 and the adjusting chassis 400 are connected via a positioning structure 700 .
[0062] The positioning structure 700 includes a positioning pin 710 and a positioning socket 720. The number of the positioning sockets 720 is set to two, and the two positioning sockets 720 are respectively set on the limit rod 500 and the adjustment chassis 400. The central axis of the positioning socket 720 is inclined relative to the central axis of the limit rod 500, and the two positioning sockets 720 are connected to each other.
[0063] The positioning pin 710 is plugged into and matched with the two positioning holes 720 . By means of the positioning pin 710 and the positioning holes 720 , the relative fixation of the limit rod 500 and the adjustment base plate 200 can be completed after the positioning pin 710 is inserted into the two positioning holes 720 .
[0064] Specifically, in this embodiment, a connecting rope 730 is further provided between the positioning pin 710 and the limiting rod 500. By providing the connecting rope 730, the positioning pin 710 is not easily lost, thereby preventing the loss of the positioning pin 710 from affecting the normal use of the orthopedic fluoroscopy auxiliary device.
