Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to an orthopedic bone-setting plate fixer. Background Art

[0002] Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the musculoskeletal system, and uses drugs, surgery and physical methods to maintain and develop the normal form and function of this system. With the changes of the times and society, the spectrum of orthopedic injuries has changed significantly. For example, diseases such as bone and joint tuberculosis, osteomyelitis, and poliomyelitis have decreased significantly, while trauma caused by traffic accidents has increased significantly. Bone plates are perforated plate-shaped fracture internal fixation devices. In clinical practice, they are often used in conjunction with bone screws or bone wires. Common bone plates are long strips.

[0003] At present, there is a clear trend towards minimally invasive orthopedics. Small incisions and minimally invasive plate osteosynthesis are limited exposures. Currently, there is no relevant instrument that can stably control the center position of the plate to allow the plate to fit directly against the fracture surface. Now, it still depends on the clinical experience of the surgeon to expose the bone surface and press to expose the fixed position of the plate. If the fluoroscopy finds that the plate is offset and not centered, it will cause a misalignment deviation in the fit with the fracture surface, making it impossible to disperse stress, reducing the fixation effect of the plate, and ultimately affecting the rapid healing of the patient's fracture position, which will prolong the patient's recovery period. Summary of the invention

DETAILED DESCRIPTION

[0036] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment, this embodiment provides an orthopedic bone plate fixator, such as Figure 1 As shown, it includes: a fixator, the fixator has a long clamp handle 1A and a short clamp handle 1, one end of the long clamp handle 1A and the short clamp handle 1 is transversely bent and provided with a holding ring, the long clamp handle 1A and the short clamp handle 1 are cross-distributed, and a pin is provided for rotation at the cross position, the long clamp handle 1 and the short clamp handle 1 cross to form a clamp structure, and the end of the long clamp handle 1A and the short clamp handle 1 away from the holding ring is set as the clamping end. Clinically, when using it, the surgeon holds the two holding rings with one hand to control the long clamp handle 1A and the short clamp handle 1 to rotate around the pin, and can selectively separate the clamping ends of the long clamp handle 1A and the short clamp handle 1, that is, expand or reduce the clamping gap size of the clamping end of the clamp, so as to be suitable for bones of different shapes and different bone diameters.

[0038] like Figure 1 , Figure 3 and Figure 4As shown, the pliers handle is set to be one long and one short, and a telescopic member is provided on the outer wall of the short pliers handle 1, and a clip 15 is provided at the end of the telescopic member. Specifically, the telescopic member includes an I-shaped slider 12, a connecting rod 13 fixed to the bottom wall of the I-shaped slider 12, and a bottom plate 14 fixed to the end of the connecting rod 13. The short pliers handle 1 is provided with a sliding hole 11 for the I-shaped slider 12 to slide and engage. The connecting rod 13 is located at the side of the short pliers handle 1, and the clip 15 is fixed on the side wall of the bottom plate 14 facing the long pliers handle 1A. The I-shaped slider 12 is tightly engaged with the sliding hole 11. When the short pliers handle 1 is in a vertical downward state, the I-shaped slider 12 will not slide down along the sliding hole 11 due to the gravity of the connecting rod 13 and the bottom plate 14. When a downward thrust is given to the I-shaped slider 12, the telescopic member can be adjusted to slide downward relative to the short pliers handle 1.

[0039] like Figure 1 and Figure 6 As shown, a second clamp 16 is provided at the end of the long clamp handle 1A. Here, two clamps 15 are provided, and one clamp 16 is provided, which is located below the two clamps 15. A clamping space is formed between the second clamp 16 and the first clamp 15. Figure 5 As shown, further, it also includes a compression sheet 17 fixed to the bottom wall of the clip 15, the compression sheet 17 is an arc-shaped elastic sheet extending downwardly, and the compression sheet 17 can be Figure 5 The bending deformation is in the direction indicated by the arrow A. The greater the deformation, the greater the elastic potential energy and the greater the clamping force. When the clamp 15 presses the orthopedic steel plate to fit the side of the bone, the end of the pressing piece 17 presses down on the side of the bone at an angle, and the bone is pressed toward the side of the long clamp handle 1A. In this way, the bone is not only clamped in the up and down direction, but also further limited at the side of the bone by the pressing piece 17 and the long clamp handle 1A, thereby enhancing the fixation stability.

[0040] In clinical practice, pliers are used to pull and reset the fracture position, correct the fracture displacement, and achieve the purpose of temporary fixation. Subsequently, the fracture position is fixed by a steel plate, and the patient slowly recovers in the later stage. It is precisely because the shapes and diameters of bones at different positions are different that in order to increase the convenience of using pliers, the position of the telescopic part is adjusted according to the bone diameter of the fracture position, and the position of the clamp 15 relative to the clamp 2 16 can be adjusted synchronously, thereby adjusting the height of the clamping space. In addition, the clamp 15 is staggered with the long clamp handle 1A. When the long clamp handle 1A and the short clamp handle 1 rotate and merge, the end of the clamp 15 can continue to move forward over the side of the long clamp handle 1A, so that the long clamp handle 1A and the short clamp handle 1 rotate and merge around the pin without affecting the clamping end.

[0041] During the operation, anesthesia and exposure are first performed. Under effective anesthesia, the skin, subcutaneous tissue, fat layer, etc. are cut to expose the fracture site. The fracture is anatomically reduced by manipulation or instruments, and then a steel plate is placed according to the fracture position, and the steel plate is close to the bone surface. According to the size of the bone diameter, the space size is adjusted, and the clip 15 is pressed down to fit the orthopedic steel plate on the side of the bone. The clip 2 16 is used to fit on the opposite side of the bone. The doctor holds the fixator still to achieve temporary fixation of the steel plate. The steel plate can firmly fix the fracture end to prevent displacement and create good conditions for fracture healing. Then, screws are used to fix the steel plate and the bone. By providing continuous fixation and support, it helps the formation and growth of bone callus and accelerates the fracture healing process. The length and number of locking screws need to be determined according to the specific situation. Finally, the incision is rinsed and sutured to complete the operation.

[0042] In summary, two clamp handles, one long and one short, are used, and a telescopic part capable of adjusting the position of the clip 15 is provided at the end of the short clamp handle 1. The clamping space between the clip 15 and the clip 2 16 is adjusted according to the requirements of the steel plate fixation at the fracture position, so as to make the steel plate highly fit to the fracture surface. As long as the surgeon holds the position of the fixator unchanged, the position of the steel plate fitted to the fracture surface will not change, which helps maintain the normal anatomical structure of the fracture site, is beneficial to the recovery of limb function, prevents the steel plate from being displaced from the fracture surface, and fails to disperse stress, thereby reducing the fixation effect of the steel plate and reducing the risk of complications such as nonunion of the fracture and abnormal healing.

[0043] In this embodiment, in addition to Figure 1 The clip 2 16 shown is fixed to the bottom wall of the long forceps handle 1A, and forms a clamping space with the clip 15 up and down. The size of the clamping space can be adjusted to meet the use requirements of different bone diameters by simply adjusting the position of the clip 15. In order to further reduce secondary damage to the patient during surgery, the smaller the incision at the surgical site, the better. If the incision is small, the blood supply to the fracture end will be less damaged, and the periosteum will be less damaged, which is less likely to cause delayed healing or even nonunion. In this case, when the clip 2 16 is fixed to the end of the long forceps handle 1A, the lateral width is large, which makes it inconvenient to quickly insert the clip 2 16 into the incision along the incision direction and place it on the lower side of the bone surface. Therefore, by rotating the end of the long forceps handle 1A and the clip 2 16, the clip 2 16 can be rotated around the rotation position to adjust the parallel distribution or vertical distribution between the clip 2 16 and the clip 1 15. Figure 6 As shown, first rotate the second clamp 16 around the rotation point until the first clamp 15 is vertical, and place the long forceps handle 1A along the incision through the subcutaneous tissue and fat layer to the side of the fracture site, and then use the forceps to surround the fracture site as shown in FIG. Figure 6Rotate the second clamp 16 in the direction indicated by arrow B until the second clamp 16 is parallel to the first clamp 15. At this time, the second clamp 16 can be placed on the lower side of the fracture position to form a clamping structure for clamping the bone in cooperation with the first clamp 15.

[0044] The design of the adjustable direction of the second clip 16 has relatively low requirements on the clinical operation skills of the surgeon, making it convenient for the surgeon to pass through the subcutaneous tissue and fat layer at the best angle, without the need to use auxiliary instruments to significantly expand the incision, thereby avoiding enlargement of the incision due to expansion.

[0045] After the above-mentioned fixator presses the steel plate onto the bone surface, the doctor needs to continuously apply force with his hands to rotate the long forceps handle 1A and the short forceps handle 1 around the pin and close the clamping ends. Once the force is slightly relaxed, the clamping ends of the long forceps handle 1A and the short forceps handle 1 are separated, which may easily cause the steel plate to shake and slide sideways on the bone surface.

[0046] For this purpose, it also includes limiters, such as Figure 7 and Figure 8 As shown, the limiting member includes two limiting slide plates 3, and a sliding hole 2 is opened on the long clamp handle 1A. The two limiting slide plates 3 are respectively located at the two sides of the long clamp handle 1A, and a connecting block 31 that slides through the sliding hole 2 is fixed between the two limiting slide plates 3; the limiting slide plate 3 can slide up and down along the sliding hole 2 to adjust the position by using the connecting block 31, and the connecting block 31 is tightly connected with the inner wall of the sliding hole 2. In the absence of external force, the connecting block 31 will not slide easily. Fig. 9 As shown, the side wall of the limiting slide plate 3 is provided with a plurality of insertion notches 33, and the clip 15 is slidably inserted into the insertion notches 33, as shown in FIG. Fig.10 As shown, a plug 32 is provided on the top wall of the insertion notch 33 , and a plurality of insertion holes 18 capable of being plugged with the plug 32 are provided on the clip 15 .

[0047] First, adjust the clamping space between the clamp 15 and the clamp 2 16 according to the bone diameter, and then rotate the long clamp handle 1A and the short clamp handle 1 around the pin to close the clamping ends. Here, the clamp 15 is an arc-shaped structure, which is convenient for smooth insertion into the insertion gap 33. The end of the clamp 15 slides over the side of the long clamp handle 1A and continues to move forward to insert into the insertion gap 33 of the limiting slide 3. As the clamping ends of the two clamp handles continue to close together, the downward pressure of the pressing plate 17 on the bone surface becomes greater. After the steel plate is stably pressed down on the bone surface, the limiting slide 3 is moved along the Figure 7 Slide in the direction indicated by arrow C to insert the plug 32 in the insertion notch 33 into a corresponding plug hole 18. After that, the doctor only needs to hold the fixator and does not need to continuously apply force to hold the two holding rings, which reduces physical exertion. Figure 8Slide in the direction indicated by arrow D to disengage the plug 32 from the socket 18 , and then separate the long clamp handle 1A and the short clamp handle 1 to pull the clip 15 out of the insertion notch 33 .

[0048] It should be noted that the height of the insertion notch 33 is greater than the sum of the thickness of the clip 15 and the height of the plug 32, and the height of the sliding hole 2 is greater than the height of the limiting slide 3. In this way, the space in the insertion notch 33 can meet the requirements of the clip 15 to be smoothly inserted without touching the end of the plug 32, and at the same time, the sliding hole 2 has enough height to meet the requirements of the limiting slide 3 to slide up and down.

[0049] In addition, in order to further enhance the stability of the steel plate being pressed, a guide is also included, such as Figure 2 As shown, the guide includes two arc-shaped guide plates 2, and an arc-shaped connecting plate 22 is fixed between the two arc-shaped guide plates 2, the bottom end of the outer wall of one arc-shaped guide plate 2 is fixedly connected to the side wall of the clamping piece 15, and an interlacing gap is provided between the two arc-shaped guide plates 2, and the interlacing gap is used to lock the screw guide. At the same time, the guide also includes a fixing sleeve 21 threadedly sleeved on the outer wall of the two arc-shaped guide plates 2, a buffer hole is provided on the side wall of the arc-shaped guide plate 2, and an elastic sheet 23 is fixed on the top wall of the buffer hole, and a protrusion 24 extends from the bottom end of the elastic sheet 23 facing the side wall of the interlacing gap, and the upper end surfaces of the two protrusions 24 form a supporting plane, and the supporting plane is used to support the locking screw cap. An inclined plate 25 is fixed to the side wall of the elastic sheet 23 facing away from the interlacing gap, and the fixing sleeve 21 rotates and feeds downward, and the inner wall of the fixing sleeve 21 continues to rotate after contacting the inclined surface, which can horizontally squeeze the inclined plate 25, and can deform the elastic sheet 23 into the interlacing gap, thereby adjusting the size of the gap between the two protrusions 24.

[0050] After the fixator presses the steel plate down and positions it on the bone surface, the locking screw is directly inserted into the interpenetrating gap, and the two arc-shaped guide plates 2 are used to enclose the outside of the locking screw. There is no need to support the locking screw. The diameter of the selected locking screw varies according to the bone diameter, so the gap between the two protrusions 24 is pre-adjusted to ensure that the two protrusions 24 can stably support the nail cap of the locking screw. The locking screw can be selected by a screwdriver to pass through the locking hole of the steel plate and then drilled into the bone, while the nail cap of the locking screw is retained in the interpenetrating gap. In this state, the fixator, steel plate, and bone are temporarily fixed together. The doctor holds the fixator to prevent the steel plate from shaking and dislocating. When other locking screws pass through the fixed holes of the steel plate and drill into the bone in a predetermined manner, the locking screw passing through the interpenetrating gap can be reversely rotated and removed.

[0051] In addition, the bottom wall of the arc guide plate 2 is arranged at the same height as the bottom wall of the clamp 15. This design prevents the bottom wall of the arc guide plate 2 from being lower than the clamp 15 and contacting the upper end surface of the steel plate, affecting the effective downward pressing operation of the clamp 15 on the steel plate.

[0052] A guide is used as a locking bolt to pass through the locking hole of the steel plate and drill into the bone. In addition to being able to temporarily fix the fixator, steel plate, and bone together to prevent the steel plate from shaking, another purpose is to reduce the number of fixators or bone clamps used clinically. Only one fixator is needed to limit one end of the steel plate, and no fixator or bone clamp is needed at the other end. This is very suitable for small incision surgical operations in clinical practice.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
