Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a broken bone auxiliary traction device. Background Art

[0002] Bone traction is a common medical treatment method; it uses the principle of action and reaction in mechanics to relieve the tension of soft tissue at the fracture or dislocation through the traction of gravity, thereby reducing the fracture or dislocation.

[0003] At present, the main types of fracture traction include femoral condyle traction, tibial traction, ulnar olecranon traction, etc.; and depending on the type of fracture traction, the Brown frame and traction standards used in treatment will also be different, for example:

[0004] When performing femoral condyle traction, the patient's femur needs to be placed against the inclined section of the Brown's frame, and the patient's tibia needs to be placed against the horizontal section of the Brown's frame, so that the patient's lower limbs are in a natural shape; then a horizontal line perpendicular to the femur is made on the upper edge of the patella, and a vertical line intersecting with the horizontal line on the upper edge of the patella is made along the anterior edge of the fibular head and the highest point of the medial femoral condyle. The intersection is used as the entry and exit point of the needle, and the Kirschner wire is used to puncture from the inside to the outside at the entry and exit point; after the puncture is completed, the traction arch is connected to the two ends of the Kirschner wire. Then, hook the traction rope with a heavy hammer or weight tied to it on the traction bow, and use the pulley to make the heavy hammer or weight fall naturally. It should be noted that the weight of the heavy hammer or weight used for femoral condyle traction is 1 / 10 to 1 / 7 of the patient's body weight. The traction direction of the traction rope usually needs to be parallel to the axis of the femur. However, because maintaining the traction force in the same direction for a long time may cause excessive stretching or damage to soft tissues such as muscles and ligaments, the medical staff will adjust it according to the patient's condition.

[0005] When performing tibial traction, the patient's femur needs to be placed against the inclined section of the Brown's frame, and the patient's tibia needs to be placed against the horizontal section of the Brown's frame, so that the patient's lower limbs are in a natural shape; then, 1-1.5 cm below the tibial tuberosity is used as the entry and exit points, and a Kirschner wire is used to puncture from the outside to the inside at the entry and exit points; after the puncture is completed, the traction bow is connected to both ends of the Kirschner wire, and then the traction rope with a heavy hammer or weight is hooked on the traction bow, and the heavy hammer or weight is placed in a naturally falling state through the pulley; it should be noted that the weight of the heavy hammer or weight used for tibial traction is 1 / 10 to 1 / 7 of the patient's body weight, and the traction direction of the traction rope needs to be adjusted according to the fracture or dislocation of the tibia;

[0006] When performing traction on the olecranon, the patient is required to lie supine with the elbow flexed 90 degrees, hang the wrist under the traction frame with a sling, and keep the forearm neutral; then, use the entry and exit points 2 cm below the apex of the olecranon and one horizontal finger beside the ulnar crest, and use a Kirschner wire to puncture from the inside to the outside at the entry and exit points; after the puncture is completed, connect the traction bow to the two ends of the Kirschner wire, and then hook the traction rope with a heavy hammer or weight tied to it on the traction bow, and use the pulley to make the heavy hammer or weight fall naturally; it should be noted that the weight of the heavy hammer or weight used for traction of the olecranon is 1 / 20 of the patient's body weight.

[0007] Affected by the different types of fracture traction, although the existing fracture traction equipment (such as a bone traction device proposed in the Chinese patent with publication number CN213098249U) can meet the use conditions of a certain type of fracture traction; but in the process of use, firstly, it cannot be universally applied to different types of fracture traction, resulting in the need for orthopedics to be equipped with a variety of styles of Brownian frames and traction frames, which are inconvenient to find when using and occupy a large amount of storage space; secondly, it is not easy to adjust. Most of the existing Brownian frames are integrally welded or bolted. When adjusting the traction direction, pulleys of different angles need to be added, which is not conducive to medical staff to adjust the direction of the traction force.

[0008] As is known from the above, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] See also Figures 1 to 8 , the present invention provides a fractured bone auxiliary traction device, comprising a patient bed pad 1, an upper body carrier plate 4, a femoral carrier plate 5 and a tibial carrier plate group 6;

[0047] The patient mattress board 1 is fixedly installed on the bed, the upper body carrier board 4 is slidably arranged above the patient mattress board 1, and the upper body carrier board 4 is provided with a rotating shaft 1 41 at one end near the end of the bed; one end of the femoral carrier board 5 is rotatably installed on the rotating shaft 1 41, and the other end is provided with a rotating shaft 2 51; the tibial carrier board group 6 includes a support plate 61 and a bearing plate 62, and the support plate 61 and the bearing plate 62 are both rotatably installed on the rotating shaft 2 51, and the support plate 61 and the bearing plate 62 are mutually embedded, and the end of the bearing plate 62 near the end of the bed is rotatably connected with a plurality of telescopic hooks 621; in addition, both sides of the top of the patient mattress board 1 near the end of the bed are connected with The protective rod 11, the two protective rods 11 are both provided with a slide groove 12 in the vertical direction, and between the two protective rods 11 from bottom to top are a baffle 13, a support rod 14 and a support rod 2 15; and the support rod 14 and the support rod 2 15 are both vertically slidably installed between the slide grooves 12 of the two protective rods 11, and both ends of the support rod 14 and the two ends of the support rod 2 15 are provided with fixing parts 2 that fix themselves between the slide grooves 12 of the two protective rods 11, and a guide part 1 3 is installed on the support rod 2 15; in this way, before treatment, the medical staff first flips the bearing plate 62 to the top of the femoral bearing plate 5, and then The carrier plate 4 is pushed toward the tail side of the bed; because the baffle 13 blocks the support plate 61, the femoral carrier plate 5 is turned over based on the rotation axis 1 41, and the support plate 61 is turned over based on the rotation axis 2 51; so that the femoral carrier plate 5 and the support plate 61 form a pagoda shape, and the femoral carrier plate 5 is in an upward tilted state based on the upper body carrier plate 4; then the medical staff adjusts the support rod 14 to make it flush with the highest point of the femoral carrier plate 5, and uses the fixing member 2 to fix the support rod 14, and then turns the carrier plate 62 so that the telescopic hook 621 on it is hooked on the support rod 14, so that the carrier plate 62 is in a state parallel to the patient's mattress board 1, thereby forming A support structure similar to a Brown's frame, and the support structure is composed of multiple triangles, and the support effect is stronger than that of the existing Brown's frame; in addition, because the natural morphology of the lower limbs of different patients may be different, the angle formed by the femoral support plate 5 and the support plate 62 does not necessarily match the angle formed by the femur and the tibia; in this regard, the medical staff can adjust the movement distance of the upper body support plate 4 to adjust the angle formed by the femoral support plate 5 and the support plate 62 to match the natural morphology of the lower limbs of different patients; at the same time, in order to ensure that the support plate 62 is always in a state parallel to the patient's mattress board 1, the medical staff also needs to adjust the height of the support rod 14 accordingly;

[0048] Furthermore, when performing traction on a broken bone, the present invention uses a Kirschner wire to puncture the patient's traction site, connects the traction bow to the two ends of the Kirschner wire, and then hooks the traction rope with a heavy hammer or weight tied to it on the traction bow, and uses a guide piece 3 to make the heavy hammer or weight fall naturally, so as to perform traction on the broken bone; and depending on the type of traction on the broken bone, the medical staff can adjust the height of the support rod 2 15 according to the specific situation, so as to adjust the relative position of the guide piece 3 and the traction site; for example, when performing traction on the femoral condyle, the support rod 2 15 can be adjusted to rise or fall, so that the traction rope between the guide piece 3 and the Kirschner wire is in a state parallel to the femoral axis, so that the traction direction meets the standard of femoral condyle traction; in this way, the present invention can assist medical staff in performing different types of traction on broken bones, and is universal; and it is convenient for medical staff to adjust the traction direction according to the type of traction on broken bones and the actual situation of the broken bones.

[0049] See also Figure 4 , Figure 6 , Figure 7 Preferably, when traction of the femoral condyle is performed, the traction direction of the traction rope usually needs to be parallel to the axis of the femur, which requires medical personnel to make judgments based on experience and adjust the height of the guide member 3, and errors are inevitable; in this regard, the two opposite sides of the femoral support plate 5 of the present invention are both provided with obturators along their own long axis direction, and positioning rods 52 are slidably arranged in the two obturators; and the support rod 15 is provided with a positioning groove 151 that cooperates with the positioning rod 52 in the horizontal direction; thereby, when traction of the femoral condyle is performed, the positioning rod 52 is pulled out of the obturator hole, and the height of the support rod 15 is adjusted according to the positioning rod 52, so that the end of the positioning rod 52 is inserted into the positioning groove 151 of the support rod 15 ; Since the extension direction of the positioning rod 52 is the same as the long axis direction of the femoral plate 5, and the patient's femur is placed against the femoral plate 5, the axis of the femur is also in a relatively parallel state with the extension direction of the positioning rod 52, so the axis of the femur can be quickly determined, providing an intuitive reference for the traction direction; and when adjusting the angle between the femoral plate 5 and the supporting plate 62 to match the angle formed by the femur and the tibia, the positioning rod 52 will also deflect with the femoral plate 5; the corresponding position of the support rod 2 15 will also change according to the extension direction of the positioning rod 52; so that the positioning rod 52 is always parallel to the axis of the femur, so that medical staff can quickly determine the axis of the femur when treating different patients.

[0050] See also Figure 1 , Figure 2Specifically, a pushing member 7 is provided at one end of the patient bed mattress board 1 close to the head of the bed, which pushes the upper body carrier plate 4 to move toward the end of the bed foot; in this way, the medical staff can use the pushing member 7 to push the upper body carrier plate 4 to move toward the end of the bed foot, and support the upper body carrier plate 4 so that it cannot return to its original position automatically, so that the femoral carrier plate 5 and the carrier plate 62 always maintain the supporting structure, continuously supporting the patient, with a simple structure, convenient operation and strong practicality.

[0051] See also Fig. 9 Preferably, one end of the femoral loading plate 5 rotatably mounted on the rotating shaft 41 can move axially along the rotating shaft 41; in this way, by pushing the femoral loading plate 5 to move axially along the rotating shaft 41, the femoral loading plate 5 and the tibial loading plate group 6 can be changed in position as a whole, so that the femoral loading plate 5 and the tibial loading plate group 6 can be moved from the right leg to the left leg or from the left leg to the right leg; in this way, broken bone traction treatment can be performed for different injured parts, with a wider range of applications and a simple operation method.

[0052] See also Figure 5 Specifically, the guide member 3 includes a pipe clamp, a short rod, a channel steel and a guide wheel; wherein the pipe clamp is installed on the support rod 2 15, the short rod connects the channel steel and the pipe clamp, and the guide wheel is installed in the notch of the channel steel; thereby, by loosening the pipe clamp and rotating it appropriately, the relative position relationship between the guide wheel and the Kirschner wire can be slightly corrected, so that the medical staff can adjust the traction direction according to the actual situation; and when the femoral loading plate 5 and the tibial loading plate group 6 change their positions as a whole, the pipe clamp can also be loosened and dragged to move along the support rod 2 15, so as to ensure that the position of the guide wheel always corresponds to the traction position.

[0053] See also Figure 1 , Fig.10 , Fig.12Preferably, a hanger 42 is provided above the upper body carrier 4, and the hanger 42 consists of a horizontal section and two vertical sections connected to the two ends of the horizontal section and perpendicular to the horizontal section; the two vertical sections of the hanger 42 are respectively connected to the two opposite sides of the patient's mattress board 1; the horizontal section of the hanger 42 is provided with a second slide groove 421 along its own long axis direction, and a guide member 2 8 is installed above the horizontal section of the hanger 42, and a guide member 3 9 is installed at the outer end of the connection between the horizontal section and the vertical section of the hanger 42; in this way, when the patient's ulna olecranon bone needs to be pulled, the patient's upper limbs are made to lie flat on the upper body carrier 4, and then the patient is supine and the elbow is bent 90 degrees, and the wrist is suspended using The sling is hung below the hanger 42, and the forearm is kept neutral; then, 2 cm below the apex of the olecranon and one horizontal finger beside the ulnar crest are used as the entry and exit points, and a Kirschner wire is used to puncture from the inside to the outside at the entry and exit points; after the puncture is completed, the traction bow is connected to the two ends of the Kirschner wire, and then the traction rope hook with a heavy hammer or weight is hung on the traction bow, and after being guided by the guide member 2 8, the heavy hammer or weight is placed in a naturally falling state through the guide member 3 9, thereby completing the broken bone traction of the olecranon; in summary, the present invention can not only assist medical staff in performing femoral condyle traction and tibial traction, but also support traction of the olecranon, and has a wider range of applications.

[0054] See also Fig.10 Specifically, the guide member 2 8 includes a screw, a channel steel and a guide wheel, the guide wheel is installed in the notch of the channel steel, one end of the screw is connected to the channel steel, and the other end passes through the second slide groove 421 to extend to the bottom of the horizontal section of the hanger 42 and is provided with a fixing member 2; the guide member 3 9 includes two relatively arranged mounting plates and a guide wheel installed between the two mounting plates; because the patient has a left and right arm when performing traction on the fracture of the ulnar olecranon, the present invention sets the screw in the second slide groove 421, and the medical staff can push the screw to move in the second slide groove 421 after loosening the fixing member 2, so as to match the patient's left and right arms for traction on the fracture of the ulnar olecranon, which is flexible to use and has a wider range of applications.

[0055] See also Figure 1 , Fig.11Preferably, two opposite sides of the patient's mattress board 1 are provided with slide rails 16 at one end close to the head of the bed, and electric sliders 17 are slidably arranged in the two slide rails 16, and the two electric sliders 17 are in the same plane and slide synchronously; the two electric sliders 17 are connected to a screw rod on the side away from the patient's mattress board 1, and the two screw rods are provided with fixing members 2; the two vertical sections of the hanger 42 are provided with a slide groove 3 422 along their own long axis direction, and the two slide grooves 3 422 are respectively slidably sleeved on the periphery of the two screw rods, and the two vertical sections of the hanger 42 are always restricted to the screw rod by the fixing member 2; due to the different heights of patients, there may be position deviations when traction is performed on the fractured bone of the ulna olecranon bone; therefore, the present invention uses a synchronously sliding electric slider 17 to drive the hanger 42 to slide along the slide rail 16, and the position of the hanger 42 can be adjusted according to the electric slider 17 The sliding condition of the hanger 42 can be adjusted to match patients of different heights for traction of the fractured olecranon bone; and considering that the different arm lengths of the patients may affect the use of the hanger 42 (for example, a longer arm causes the hanger 42 to interfere with the forearm when the patient flexes his elbow in the supine position, and the patient cannot flex his elbow 90 degrees and keep his forearm neutral), the present invention provides a slide groove 422 along the long axis direction of the two vertical sections of the hanger 42, and the medical staff can adjust the height difference between the horizontal section of the hanger 42 and the upper body carrier plate 4 by loosening the fixing piece 2, so that the hanger 42 is suitable for patients with different arm lengths; in addition, when the hanger 42 is not needed, the hanger 42 can be put in a rotatable state by loosening the fixing piece 2, and then the hanger 42 is rotated to the side of the patient's mattress board 1 close to the head of the bed, and the hanger 42 is stored to prevent the hanger 42 from hitting the patient or others.

[0056] It should be noted that the pusher 7 of the present invention is a stud, one end of which abuts against the upper body carrier plate 4, and the other end penetrates the mattress board 1 and is connected to the crank; those skilled in the art can choose other pushers 7 according to actual conditions.

[0057] It should be noted that the fixing member 2 of the present invention is a nut, and two oppositely positioned paddles are fixedly connected to one side of the nut; those skilled in the art may select other fixing members 2 according to actual conditions.

[0058] The working process of the present invention is:

[0059] Preparatory stage: the medical staff first flips the supporting plate 62 to the top of the femoral supporting plate 5, and then uses the pushing member 7 to push the upper body supporting plate 4 to the end of the bed; at this time, the baffle 13 blocks the support plate 61, the femoral supporting plate 5 flips based on the rotation axis 1 41, and the support plate 61 flips based on the rotation axis 2 51; the femoral supporting plate 5 and the support plate 61 form a pagoda shape, and the femoral supporting plate 5 is in an upward tilted state based on the upper body supporting plate 4; then the medical staff adjusts the support rod 14 to make it flush with the highest point of the femoral supporting plate 5, and uses the fixing member 2 to fix the support rod 14, and then flips the supporting plate 62 so that the telescopic hook 621 on it is hooked on the support rod 14, so that the supporting plate 62 is in a state parallel to the patient's mattress board 1.

[0060] Femoral condyle traction: let the patient's upper limbs lie flat on the upper body support plate 4, so that the patient's femur fits the femoral support plate 5, and the patient's tibia fits the support plate 62, so that the patient's lower limbs are in a natural shape; then make a horizontal line perpendicular to the femur on the upper edge of the patella, and make a vertical line intersecting with the horizontal line of the upper edge of the patella along the highest point of the anterior edge of the fibular head and the medial femoral condyle, and use the intersection as the entry and exit point of the needle, and use the Kirschner wire to puncture from the inside to the outside at the entry and exit point; after the puncture is completed, connect the traction bow with the two ends of the Kirschner wire, and then hook the traction rope with a heavy hammer or weight tied to it on the traction bow, and make the heavy hammer or weight in a naturally falling state through the guide member 13; at the same time, pull the positioning rod 52 out of the obturator foramen, and adjust the height of the support rod 2 15 with the extension direction of the positioning rod 52 as the reference line, so that the traction rope between the guide member 13 and the Kirschner wire is in a state parallel to the femoral axis; that is, the femoral condyle traction is completed.

[0061] Tibial traction: let the patient's upper limbs lie flat on the upper body support plate 4, let the patient's femur fit the femoral support plate 5, and the patient's tibia fit the support plate 62, so that the patient's lower limbs are in a natural shape; then use 1-1.5 cm below the tibial tuberosity as the entry and exit points, and use Kirschner wires to puncture from the outside to the inside at the entry and exit points; after the puncture is completed, connect the traction bow with both ends of the Kirschner wire, and then hook the traction rope with a heavy hammer or weight tied to it on the traction bow, and make the heavy hammer or weight in a natural falling state through the guide piece 3; unlike femoral condyle traction, tibial traction does not require the use of a positioning rod 52, and the traction direction of the traction rope needs to be adjusted according to the fracture or dislocation of the tibia; that is, tibial traction is completed.

[0062] Traction of the olecranon: let the patient's upper limb lie flat on the upper body carrier 4, and adjust the height and position of the hanger 42 and the position of the guide member 2 8 according to the patient's arm length, lying position and arm to be traction; after the adjustment is completed, let the patient lie supine with his elbow flexed 90 degrees, hang the wrist under the traction frame with a sling, and keep the forearm neutral; then use 2 cm below the apex of the olecranon and one horizontal finger beside the ulna crest as the entry and exit points, and use a Kirschner wire to puncture from the inside to the outside at the entry and exit points; after the puncture is completed, connect the traction bow with both ends of the Kirschner wire, and then hang the traction rope hook with a heavy hammer or weight tied to it on the traction bow, and after being guided by the guide member 2 8, let the heavy hammer or weight be in a naturally falling state through the guide member 3 9; that is, the traction of the olecranon is completed.

[0063] In summary, the present invention provides a fracture auxiliary traction device, which arranges a traction structure on a patient mattress board, and directly installs the patient mattress board on the bed for use; on the one hand, when fracture traction is not needed, the device can be used as a normal bed by covering the upper surface of the device with bedding, which will not hinder the patient's daily life and the treatment of medical staff; on the other hand, when fracture traction is performed, the medical staff can directly place the patient on the patient mattress board for treatment after lifting the bedding, without the need to temporarily build or find a suitable Brown's frame or traction frame, thereby shortening the preparation period before treatment; by arranging the second adjustable support rod, it is convenient for medical staff to adjust the traction direction according to the type of fracture traction and the actual situation of the fracture, and assist medical staff to perform different types of fracture traction, which has universality; by arranging a positioning rod that is always parallel to the femoral support plate, it can provide an intuitive reference for the traction direction, which is convenient for medical staff to quickly determine the axis of the femur when treating different patients; by pushing the femoral support plate to move axially along the first axis, The femoral plate and the tibial plate group can be changed in position as a whole, so that the femoral plate and the tibial plate are moved from the right leg to the left leg or from the left leg to the right leg; in this way, traction treatment of broken bones is performed for different injured parts, the application range is wider, and the operation method is simple; by loosening the pipe hoop and rotating it appropriately, the relative position relationship between the guide wheel and the Kirschner wire can be slightly corrected, so that the medical staff can adjust the traction direction according to the actual situation; and when the femoral plate and the tibial plate group are changed in position as a whole, the pipe hoop can also be loosened and dragged to move along the support rod 2, so as to ensure that the position of the guide wheel always corresponds to the traction position; by setting the hanger and the second and third guide members used in conjunction, not only can the medical staff be assisted in femoral condyle traction and tibial traction, but also the ulna olecranon traction can be supported, so that the application range is wider; by loosening the fixing member to make the hanger in a rotatable state, and then rotating the hanger to the side of the patient's mattress board close to the bed head, the hanger can be stored to prevent the hanger from hitting the patient or others when not in use.
