Description

Technical Field

[0001] This invention relates to the field of biomedical technology, and in particular to a stabilizing traction frame for orthopedic incisions. Background Technology

[0002] An orthopedic incision stabilization traction frame is an auxiliary medical device used in orthopedic surgery. Its main function is to maintain the tension stability of the surgical incision while expanding the surgical field of view to facilitate the surgeon's operation. This traction frame usually has an adjustable function, which can be adapted to different patient differences and surgical sites to provide sufficient support, ensure that the incision remains stable during the operation, and improve the accuracy and efficiency of the operation.

[0003] In existing technologies, orthopedic incision stabilization traction frames inevitably come into contact with the patient's muscle tissue during use. Since the traction frame needs to remain fixed for a long time during surgery, when muscles, tendons, and other tissues are in a static state and the blood has coagulated, they are prone to adhesion to the traction frame. If the adhered tissues are forcibly separated when the traction frame is removed after surgery, it will cause muscle tears, affecting suturing and postoperative recovery. Summary of the Invention

[0004] To address the problems mentioned in the background section, the present invention provides an orthopedic incision stabilization traction frame.

[0005] The technical implementation of the present invention is as follows: an orthopedic incision stabilizing traction frame includes a movable frame, a first movable frame slidably connected to the movable frame, an arc-shaped support plate fixedly connected to the upper side of the first movable frame, symmetrically distributed sliding frames on the first movable frame, each of the symmetrically distributed sliding frames being fixedly connected to a scorpion tail telescopic frame, the telescopic end of the scorpion tail telescopic frame being slidably connected to two centrally symmetrically distributed L-shaped frames, a plurality of hinge frames being provided between the two L-shaped frames, adjacent two hinge frames being hinged to each other and the L-shaped frame being hinged to adjacent hinge frames, adjacent two hinge frames being rotatably connected to a rotating sleeve, the rotating sleeve being fixedly connected to a movable frame, the movable frame being fixedly connected to a contact plate, the contact plate being provided with a plurality of through holes, the movable frame being slidably connected to a second movable frame in contact with the contact plate, the second movable frame being fixedly connected to a plurality of sealing posts, the sealing posts corresponding one-to-one with the through holes, and the sealing posts being used to seal adjacent through holes.

[0006] Preferably, the telescopic part of the scorpion tail telescopic frame is rotatably connected to two bidirectional threaded rods that are threadedly connected to the two L-shaped frames that are symmetrically distributed around the center.

[0007] Preferably, the contact plate is an arc-shaped plate.

[0008] Preferably, the movable frame is slidably connected to a connecting rod, the connecting rod is fixedly connected to a U-shaped block slidably connected to the movable frame, the movable frame is slidably connected to a first connecting member, the portion of the first connecting member passing through the movable frame is fixedly connected to a second sliding frame, the U-shaped block is provided with an inclined groove, and the first connecting member is slidably connected to the inclined groove on the U-shaped block.

[0009] Preferably, a liquid-containing shell is fixedly connected to the upper side of the movable frame, the connecting rod passes through the liquid-containing shell and is slidably connected thereto in a sealed manner, a liquid-guiding shell is slidably connected to the upper side of the movable frame and the upper side of the liquid-containing shell, the liquid-guiding shell is fixedly connected to the upper end of the connecting rod, a spring is fixedly connected between the liquid-guiding shell and the liquid-containing shell, a liquid-guiding port is provided on the lower side of the liquid-guiding shell, the liquid-guiding port is used to transport liquid into the liquid-containing shell, an infusion tube is fixedly connected between the liquid-containing shell and the movable frame, the liquid-containing shell is used to transport liquid through the infusion tube to the space between the movable frame and the contact plate, and a liquid bladder is detachably connected to and communicates with the liquid-guiding shell.

[0010] Preferably, the first sliding frame is rotatably connected to a rotating rod, and the symmetrically distributed sliding frames are all slidably connected to the rotating rod. The rotating rod is provided with symmetrically distributed threaded grooves, and the sliding frames are slidably connected to a second connecting member that slides along an adjacent threaded groove on the rotating rod.

[0011] Preferably, the first sliding frame is slidably connected to a T-shaped frame, and the symmetrically distributed sliding frames all pass through the T-shaped frame. The first sliding frame is provided with a deformable element that contacts the symmetrically distributed sliding frames. The T-shaped frame contacts the deformable element. The second connecting member is slidably connected to the T-shaped frame for limiting. The T-shaped frame is used to compress the deformable element. The first sliding frame is fixedly connected to a symmetrically distributed multi-stage spring telescopic rod. The multi-stage spring telescopic rod corresponds one-to-one with the sliding frame.

[0014] Preferably, the deformable part has a frosted surface on all parts except for the smooth surface on the lower side.

[0015] The beneficial effects of this invention are as follows: When traction is applied to the muscles of the incision, the sealing column on the second sliding frame blocks the through holes on the contact plate, making the former a complete traction plate, thereby achieving stable traction of the incision muscles. When removal is required, the sealing column on the second sliding frame no longer blocks the through holes on the contact plate, making the former a porous structure, thus achieving the effect of separating the contact with the muscles of the patient's incision in sections. Compared with the prior art, this invention can achieve contact between the contact plate and the patient's incision muscles without forcibly separating the adhesions. On this basis, by injecting saline solution into the part of the patient's incision muscles, the adhesions between the contact plate and the patient's incision muscles are gradually loosened, avoiding forced separation that could lead to muscle tears. At the same time, the removal time is shortened, thereby reducing the operation time and facilitating postoperative suturing and patient recovery.

[0016] After the surgery, the sliding frame can be quickly reset by pressing the T-shaped frame, eliminating the need for manual reset. This reduces the user's workload and makes the reset process of the sliding frame more stable and controllable. Attached Figure Description

Detailed Implementation

[0031] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0032] This invention addresses the problems of adhesions caused by prolonged contact between orthopedic incision stabilizing traction frames and muscle tissue during surgery, as well as muscle tears and impaired postoperative recovery during removal. The specific solution is as follows:

[0033] Example 1

[0034] An orthopedic incision stabilizing traction frame, such as Figures 1-8As shown, it includes a movable frame 1, a first sliding frame 2 slidably connected to the movable frame 1, an arc-shaped support plate fixed to the upper side of the first sliding frame 2, symmetrically distributed sliding frames 3 on the first sliding frame 2, each symmetrically distributed sliding frame 3 fixedly connected to a scorpion tail telescopic frame 4, the telescopic end of the scorpion tail telescopic frame 4 slidably connected to two centrally symmetrically distributed L-shaped frames 5, several hinge frames 6 between the two L-shaped frames 5, adjacent two hinge frames 6 and L-shaped frames 5 and adjacent hinge frames 6 respectively hinged to each other, adjacent two hinge frames 6 are rotatably connected to a rotating sleeve 7, the rotating sleeve 7 is fixedly connected to a movable frame 8, the movable frame 8 is fixedly connected to a contact plate 9, the contact plate 9 is provided with several through holes 901, the movable frame 8 is slidably connected to a second sliding frame 10 in contact with the contact plate 9, the second sliding... The frame 10 is fixedly connected with several sealing posts 1001, each corresponding to a through hole 901. The sealing posts 1001 are used to block adjacent through holes 901. When the muscles of the incision are pulled, the sealing posts 1001 on the second sliding frame 10 block the through holes 901 on the contact plate 9, so that the sealing posts 1001 and the contact plate 9 form a complete traction plate. Thus, the muscles of the patient's incision are stably pulled by the movement of the two. When it is necessary to separate the sealing posts 1001 and the contact plate 9 from the muscles of the patient's incision, the sealing posts 1001 on the second sliding frame 10 no longer block the through holes 901 on the contact plate 9. Through the porous structure of the contact plate 9 itself, the effect of separating the sealing posts 1001 and the contact plate 9 from the muscles of the patient's incision in different areas is achieved.

[0035] like Figure 4 and Figure 5 As shown, the telescopic part of the scorpion tail telescopic frame 4 is rotatably connected to two L-shaped frames 5 that are symmetrically distributed with the center and are threaded together with a bidirectional threaded rod 501. When the bidirectional threaded rod 501 rotates, it increases or decreases the distance between the two L-shaped frames 5. The contact plate 9 is an arc-shaped plate used to limit the cutting position.

[0036] like Figures 6-10 As shown, the movable frame 8 is slidably connected to a connecting rod 11, and the connecting rod 11 is fixedly connected to a U-shaped block 12 that is slidably connected to the movable frame 8. The movable frame 8 is slidably connected to a first connecting member 13, and the part of the first connecting member 13 that passes through the movable frame 8 is fixedly connected to the second sliding frame 10. The U-shaped block 12 is provided with an inclined groove, and the first connecting member 13 is slidably connected to the inclined groove on the U-shaped block 12. When the U-shaped block 12 moves downward, the inclined groove of the U-shaped block 12 squeezes the first connecting member 13, causing the first connecting member 13 to move away from the adjacent contact plate 9.

[0037] like Figures 6-9As shown, a liquid-containing shell 14 is fixedly connected to the upper side of the movable frame 8. A connecting rod 11 passes through the liquid-containing shell 14 and is slidably connected to it in a sealed manner. A liquid-guiding shell 15 is slidably connected to the upper side of the movable frame 8 and the upper side of the liquid-containing shell 14 in a sealed manner. The liquid-guiding shell 15 is fixedly connected to the upper end of the connecting rod 11. A spring is fixedly connected between the liquid-guiding shell 15 and the liquid-containing shell 14. A liquid-guiding port 1501 is provided on the lower side of the liquid-guiding shell 15. The liquid-guiding port 1501 is used to transport liquid into the liquid-containing shell 14. An infusion tube 16 is fixedly connected between the liquid-containing shell 14 and the movable frame 8. The liquid-containing shell 14 is used to transport liquid through the infusion tube 16 to the space between the movable frame 8 and the contact plate 9. The liquid-containing shell 14 is connected to the movable frame 8 and the contact plate 9 through the infusion tube 16. A liquid bladder 1601 is detachably connected to the liquid-guiding shell 15 and communicates with it. Before use, physiological saline (as mentioned above) is added to the liquid bladder 1601. The liquid is physiological saline. The spring between the fluid guide shell 15 and the fluid holding shell 14 is used to give the fluid guide shell 15 a reset force. When the spring between the fluid guide shell 15 and the fluid holding shell 14 is not in a compressed state, the fluid guide shell 15 is not connected to the fluid holding shell 14 through the fluid guide port 1501. Conversely, when the spring between the fluid guide shell 15 and the fluid holding shell 14 is in a compressed state and the fluid guide port 1501 is exposed in the adjacent fluid holding shell 14, the fluid guide shell 15 is connected to the fluid holding shell 14 through the fluid guide port 1501. By squeezing the fluid bladder 1601, the physiological saline in the fluid bladder 1601 enters the gap between the contact plate 9 and the second sliding frame 10 through the fluid guide shell 15, the fluid guide port 1501, the fluid holding shell 14 and the infusion tube 16. Then, it flows into the gap between the patient's incision muscle and the contact plate 9 through the through hole 901, reducing the friction between the patient's incision muscle when the contact plate 9 is removed.

[0038] When surgery is required on a patient's leg bones (for illustrative purposes only), the user first pushes the device to the surgical site, then pulls the telescopic parts of both scorpion tail telescopic frames 4 upwards, causing the scorpion tail telescopic frames 4 to lift the corresponding L-shaped frame 5 and the moving frame 8 and their accessories upwards. Then, the patient's leg is placed on the arc-shaped support plate on the upper side of the first sliding frame 2, and the user performs surgery on the patient's leg.

[0039] When traction is needed on the patient's leg incision, the user presses down the telescopic parts of the two scorpion tail telescopic frames 4, causing the scorpion tail telescopic frames 4 to move the corresponding L-shaped frame 5 and the moving frame 8 and their accessories downward to the patient's incision.

[0040] When the moving frame 8 is located at the patient's incision, the user locks the telescopic parts of the two scorpion tail telescopic frames 4 (an existing locking mechanism can be used). Then, the user adjusts the distance between the two adjacent L-shaped frames 5 according to the size of the patient's incision. When the patient's incision needs to be opened to a large extent, the user rotates the bidirectional threaded rod 501 to shorten the distance between the two L-shaped frames 5. To this end, the bending degree of several hinge frames 6 on the same L-shaped frame 5 is increased to adapt to the scenario where the patient's incision needs to be opened to a large extent. Conversely, when the patient's incision needs to be opened to a small extent, the user rotates the bidirectional threaded rod 501 in the opposite direction to increase the distance between the two L-shaped frames 5, thereby reducing the bending degree of several hinge frames 6 on the same L-shaped frame 5.

[0041] After the bending degree of several hinged frames 6 on the same L-shaped frame 5 is adjusted, all contact plates 9 and corresponding sealing columns 1001 on the same L-shaped frame 5 are in contact with the muscles of the patient's incision. Then, the user controls the two sliding frames 3 to move away from each other. The sliding frames 3 drive the corresponding L-shaped frame 5, moving frame 8 and its accessories to move through the scorpion tail telescopic frame 4, thereby expanding the patient's incision to facilitate diagnosis and treatment inside the incision. Then, the two sliding frames 3 are fixed by the existing fixation equipment.

[0042] After completing the diagnosis and treatment of the patient's incision, the user shortens the distance between the two sliding frames 3 to reduce the size of the incision. The user needs to disconnect the L-shaped frame 5 from the muscles at the incision site. Details are as follows (taking the disconnection process of one L-shaped frame 5 from the muscles at the incision site as an example): The user presses the fluid guide shell 15. As the fluid guide shell 15 moves downward, it squeezes the adjacent spring and drives the adjacent connecting rod 11 to move downward synchronously. The connecting rod 11 drives the U-shaped block 12 to move downward synchronously. As the U-shaped block 12 moves, it squeezes the adjacent first connecting piece 13 through the inclined groove on it, causing the first connecting piece 13 to drive the second sliding frame 10 and the corresponding sealing column 1001 to move away from the patient's incision site (a gap is generated between the second sliding frame 10 and the contact plate 9 during the movement), so as to achieve the effect of disconnecting the contact with the muscles at the patient's incision site in sections.

[0043] Once the second sliding frame 10 and the corresponding sealing post 1001 are no longer in contact with the patient's incision, the fluid guide shell 15 communicates with the fluid collection shell 14 through its fluid guide port 1501. The fluid collection shell 14 is then connected to the gap between the contact plate 9 and the second sliding frame 10 through the infusion tube 16. Subsequently, the user squeezes the fluid bladder 1601, and the saline solution inside the fluid bladder 1601 flows through the fluid guide shell 15, the fluid guide port 1501, the fluid collection shell 14, and the infusion tube 16 into the gap between the contact plate 9 and the second sliding frame 10, allowing the saline solution to pass through the gap. The gap and the corresponding through hole 901 flow into the space between the patient's incision muscle and the contact plate 9. With the lubrication of physiological saline, the friction between the patient's incision muscle is reduced when the contact plate 9 is removed, avoiding forced separation that could cause muscle tearing. Through the above steps, the separation of the contact plate 9 from the patient's incision muscle is completed without prolonging the operation time. Then, the user lifts the telescopic parts of the two scorpion tail telescopic frames 4, so that the auxiliary parts of the telescopic parts of the scorpion tail telescopic frames 4 are away from the surgical area. At this time, other users can suture the patient.

[0044] After the user removes the auxiliary parts of the telescopic part of the scorpion tail telescopic frame 4, the user releases the liquid guide shell 15 and stops squeezing the liquid bladder 1601. Under the action of the adjacent spring, the liquid guide shell 15 drives the connecting rod 11 to move upward and reset. The connecting rod 11 drives the U-shaped block 12 to move synchronously. The inclined groove on the U-shaped block 12 squeezes the first connecting member 13, causing the first connecting member 13 to drive the second sliding frame 10 and the corresponding sealing column 1001 to move towards the contact plate 9, so that the sealing column 1001 re-seals the corresponding through hole 901.

[0045] In orthopedic surgery, traction frames are used to open the incision and provide the surgeon with a clear surgical field. However, existing traction frames achieve traction and reduction through mechanical drive of threaded rods and sliders. Although they can effectively open the incision during surgery, the reduction operation still requires manual adjustment of the threaded rods and sliders after surgery. This reduction method not only requires additional operation time for the surgeon but also increases the operation time. The above-mentioned problems are now solved by the following method.

[0046] Example 2

[0047] Based on Example 1, such as Figure 2 and Figures 11-13 As shown, the first sliding frame 2 is rotatably connected to the rotating rod 20, and the symmetrically distributed sliding frames 3 are all slidably connected to the rotating rod 20. The rotating rod 20 is provided with symmetrically distributed threaded grooves. The sliding frames 3 are slidably connected to the second connecting piece 21 that slides along the adjacent threaded grooves on the rotating rod 20. The second connecting piece 21 slides vertically along the adjacent sliding frame 3. During the rotation of the rotating rod 20, the adjacent second connecting piece 21 is pressed by the threaded groove on it, so that the second connecting piece 21 drives the sliding frame 3 to translate.

[0048] like Figures 11-13 As shown, a first sliding frame 2 is slidably connected to a T-shaped frame 22. Symmetrically distributed sliding frames 3 all pass through the T-shaped frame 22. The first sliding frame 2 is provided with deformable parts 23 that contact the symmetrically distributed sliding frames 3. The T-shaped frame 22 contacts the deformable parts 23. A second connecting piece 21 is slidably connected to the T-shaped frame 22 for limiting. The T-shaped frame 22 is used to compress the deformable parts 23. A symmetrically distributed multi-stage spring telescopic rod 24 is fixedly connected to the first sliding frame 2. Each multi-stage spring telescopic rod 24 corresponds to one of the sliding frames 3. The telescopic ends of the multi-stage spring telescopic rods 24 are fixedly connected to adjacent sliding frames 3. The T-shaped frame 22 slides vertically along the adjacent first sliding frame 2, and the deformable parts 23... As an airbag, the multi-stage spring telescopic rod 24 provides a force for the adjacent sliding frames 3 to automatically reset. The cross-section of the deformable part 23 is elliptical, with the major axis of the ellipse being vertical. The upper and lower sides of the deformable part 23 are in contact with the T-shaped frame 22 and the symmetrically distributed sliding frames 3, respectively. The lower side of the deformable part 23 is a smooth surface. The purpose of this smooth surface is to reduce the friction between it and the two sliding frames 3. Except for the smooth surface on the lower side, the other parts of the deformable part 23 are all frosted surfaces. After the deformable part 23 is deformed, its frosted surface contacts the two sliding frames 3, thereby increasing the friction between it and the two sliding frames 3, thus achieving the effect of reducing the moving speed of the sliding frames 3.

[0049] This embodiment replaces the existing fixed equipment in Embodiment 1 with a rotating rod 20 and related parts.

[0050] When surgery is required, the distance between the two sliding frames 3 needs to be increased. At this time, the user rotates the rotating rod 20. During its rotation, the rotating rod 20 presses the corresponding second connecting piece 21 through its two threaded grooves. This causes the second connecting piece 21 to move the corresponding sliding frame 3 and the scorpion tail telescopic frame 4 away from the middle of the moving first sliding frame 2. During the movement of the second connecting piece 21, it moves along the T-shaped frame 22. During the movement of the sliding frame 3, its inner side slides relative to the lower side of the deforming part 23 (during the movement of the sliding frame 3, it presses the telescopic end of the adjacent multi-stage spring telescopic rod 24, causing the telescopic part of the multi-stage spring telescopic rod 24 to retract into it). The friction between the two is reduced by the smooth surface of the lower side of the deforming part 23. After the adjustment of the distance between the two sliding frames 3 is completed, the user can stop rotating the rotating rod 20.

[0051] When surgery is no longer needed, the two sliding frames 3 should be quickly returned to the middle of the first sliding frame 2 without affecting the surgery. The specific workflow is as follows:

[0052] When the user presses the T-shaped frame 22, the T-shaped frame 22 drives the two second connecting parts 21 to move downward synchronously. During the movement of the T-shaped frame 22, the deformable part 23 is squeezed, causing the deformable part 23 to change from a vertically shaped ellipse to a horizontally distributed ellipse. After the deformable part 23 is deformed, its original left and right sides are in contact with the inner sides of the two sliding frames 3. After the second connecting part 21 moves downward and disengages from the adjacent threaded groove on the rotating rod 20, the adjacent sliding frames 3 are reset and moved under the pushing force provided by the multi-stage spring telescopic rod 24. During this process, the deformable part 23 generates friction between the sliding frames 3, thereby reducing the moving speed of the sliding frames 3 and reducing the impact force on the first sliding frame 2. Through the above, the sliding frames 3 are automatically reset in a slow state, reducing the user's workload and making the reset process of the sliding frames 3 more stable and controllable.

[0053] When the sliding frame 3 is reset and the telescopic part of the multi-stage spring telescopic rod 24 is fully extended, the user no longer presses the T-shaped frame 22. After the T-shaped frame 22 no longer applies pressure to the deformable part 23, the deformation of the deformable part 23 itself drives the T-shaped frame 22 to move upward and reset. During the movement of the T-shaped frame 22, the two second connecting parts 21 move synchronously, so that the second connecting parts 21 resume contact with the adjacent threaded grooves on the rotating rod 20.

[0054] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
