Description

Technical Field

[0001] This utility model relates to a fixation device, specifically an improved limb fixation device for orthopedic surgery, belonging to the technical field of clinical surgical physiotherapy equipment. Background Technology

[0002] As is well known, surgery refers to the treatment performed by doctors using medical instruments to remove or suture a patient's body. It involves operations performed on specific parts of the human body using instruments such as scalpels, scissors, and needles to maintain the patient's health. During surgery, pain or muscle contractions can cause the affected limb to move erratically, affecting the surgeon's work. Therefore, doctors often choose to use limb immobilization devices to fix the patient's affected limb, facilitating their own procedures.

[0003] Limb immobilization devices are commonly used auxiliary methods in orthopedic surgery to facilitate intraoperative manipulation by surgeons. Existing orthopedic limb immobilization devices generally utilize modular fixation devices, providing temporary fixation during surgery, but occasional slight movement of the limbs still occurs. This makes it difficult to guarantee absolute stability of the affected limb during robot-assisted surgery, where absolute stability is required.

[0004] Currently, existing limb fixation devices require doctors to change the direction of the support rods as needed. The support rods are limited by the rotation of the control rods, requiring simultaneous operation with both hands, which is inconvenient. Furthermore, limb fixation devices used in orthopedic surgery typically have a simple adjustable structure, making them difficult to adjust and unable to be customized to patient comfort, potentially impacting patient comfort. Additionally, some modular fixation devices are bulky, obstructing the robot's operating space.

[0005] Therefore, the key to solving the above-mentioned technical problems lies in developing a stable, reliable, and flexible improved limb fixation device for orthopedic surgery. Summary of the Invention

[0052] The connecting pipe is a flexible metal tube.

[0053] The working principle is as follows: Before using this utility model, the operator only needs to manually carry the limb fixation device with the above-mentioned design structure to the place of use.

[0054] In use, the operator only needs to install the above-mentioned limb fixation device on the corresponding position of the hospital bed according to the medical operation requirements, and fix it firmly and reliably.

[0055] Once the installation is complete and reliable, the corresponding surgery can be performed on the patient. During the surgery, when the operator needs to rotate the support rod to adjust the angle, the operator first presses down on the support rod. As the support rod moves downward, it causes the gear to disengage from the rotation limit block, putting the support telescopic rod in a compressed state. Then, the operator rotates the support rod to the predetermined position and releases it. At this time, under the elastic action of the support spring, the support telescopic rod moves upward to reset. At the same time, the gear is doubly limited by the rotation limit block and the height limit block, restoring it to its normal limit state, thus simplifying the operation and saving time. Meanwhile, the operator wraps the patient's affected limb with the cooperation of the buckle and the fixing airbag, and fixes it with the locking rod, thereby achieving fixation of the affected limb.

[0056] When the installation position needs to be adjusted, the operator first grasps the control frame and then pushes it towards the locking block. This causes the mounting rods to expand outward through the control frame, thereby widening the gap between the two mounting rods and allowing the anti-slip fixing device to be removed from the operating table. When the position is adjusted, the operator pulls the middle of the control frame away from the locking block, thereby compressing the gap between the two mounting rods and fixing the anti-slip fixing device onto the operating table.

[0057] When it is necessary to adjust the direction of the connecting pipe, rotate the connecting seat to drive the connecting pipe to rotate to the predetermined direction, and then tighten the limit bolt to fix the connecting seat on the horizontal axis rotating seat, thereby realizing the lateral rotation adjustment of the connecting pipe.

[0058] The rotating longitudinal axis seat rotates by extending and retracting the limiting telescopic rod and repeatedly engaging the abutment with the limiting groove, thereby enabling the longitudinal axis seat to drive the connected transverse axis seat to rotate. In turn, the transverse axis seat drives the connected connecting tube to rotate and limits the connection tube, thus meeting the needs of the operation.

[0059] Finally, as time goes by, once the corresponding surgery is completed, the operator only needs to remove the limb fixation device of this utility model, and then clean and disinfect it for the next cycle of use.

[0060] The beneficial effects of this utility model compared with the prior art are:

[0061] 1. Because this utility model is equipped with an adjustment transmission component, it can quickly adjust the support rod to meet adjustment requirements, thereby simplifying the operation of rotating the support rod;

[0062] 2. The adjustment transmission component in the mounting groove of this utility model cooperates with the support rod to realize the rapid lifting, resetting, rotation and limiting of the support rod, thereby improving the adjustment efficiency of the support rod;

[0063] 3. The limb fixation device of this utility model is equipped with a fixation airbag, which can provide uniform support and pressure around the patient's affected limb, helping to prevent abnormal movement or twisting of the affected limb, thereby maintaining the stability of the joint or fracture site; at the same time, the fixation airbag can reduce the patient's pain during movement or exercise, improve the patient's comfort; it can also help control the patient's posture, ensuring that the affected limb is in the correct position and angle, thus significantly improving the patient's treatment effect and rehabilitation process.

[0064] 4. The base of this utility model is equipped with an anti-slip fixing device in the fixing groove, which can quickly realize the installation, disassembly and adjustment with the operating table, and can be used for the installation and disassembly fixing of various operating tables.

[0065] 5. This utility model, through the cooperation of the horizontal axis rotating seat, the connecting seat and the limiting bolt, can quickly realize the lateral rotation and limiting of the connecting pipe;

[0066] 6. This utility model, through the mutual cooperation of the longitudinal axis rotating seat, the connecting rod and the connecting rod longitudinal axis rotating assembly connected to it, can quickly realize the longitudinal rotation and limiting of the connecting pipe by rotating the longitudinal axis rotating seat;

[0067] 7. This utility model is convenient to operate and safe and reliable. During use, the operator can easily adjust the direction of the support rod according to the specific needs of use, so as to avoid obstructing the operation of the robot surgery and avoid the problem that traditional equipment requires two hands to operate at the same time, which is inconvenient.

[0068] 8. This utility model has a simple structure and a novel and reasonable design, which ensures the safety of orthopedic surgery, provides basic support and assistance for the success of the surgery, greatly reduces the operation time, and completes orthopedic surgery in a time-saving and efficient manner. It is highly practical and also achieves better safety and efficiency in the surgical treatment of patients, ensuring the smooth progress of the entire operation. Attached Figure Description

[0140] The specific steps for using it are:

[0141] During the surgery, when the operator needs to rotate the support rod 3 to adjust the angle, the operator first presses down on the support rod 3. As the support rod 3 moves downward, it causes the gear 23 to disengage from the rotation limit block 25, putting the support telescopic rod 21 in a compressed state. Then, the operator rotates the support rod 3 to the predetermined position and releases it. At this time, under the elastic action of the support spring 22, the support telescopic rod 21 drives the support rod 3 to move upward to reset. At the same time, the gear 23 is doubly limited by the rotation limit block 25 and the height limit block 24, restoring it to its normal limit state, thus simplifying the operation and saving time. Meanwhile, the operator wraps the patient's affected limb with the cooperation of the buckle 51 and the fixing airbag 52, and fixes it with the locking rod 53, thereby achieving fixation of the affected limb.

[0142] When the installation position needs to be adjusted, the operator first holds the control frame 64 and then pushes it towards the locking block 63. This causes the mounting rods 61 to expand outward through the control frame 64, thereby widening the gap between the two mounting rods 61 and thus removing the anti-slip fixing device 6 from the operating table 8. When the position is adjusted, the operator pulls the middle of the control frame 64 away from the locking block 63, thereby compressing the gap between the two mounting rods 61 and thus fixing the anti-slip fixing device 6 onto the operating table 8.

[0143] When it is necessary to adjust the direction of the connecting pipe 73, the connecting seat 74 is rotated to drive the connecting pipe 73 to rotate to the predetermined direction. The connecting seat 74 is fixed on the horizontal axis rotating seat 72 by tightening the limit bolt 721, thereby realizing the lateral rotation adjustment of the connecting pipe 73.

[0144] The longitudinal axis rotating seat 71 rotates by extending and retracting the limiting telescopic rod 41 and repeatedly engaging the abutment 42 with the limiting groove 711, thereby enabling the longitudinal axis rotating seat 71 to drive the connected transverse axis rotating seat 72 to rotate. In turn, the transverse axis rotating seat 72 drives the connected connecting pipe 73 to rotate and limits the connection of the connecting pipe 73.

[0145] Finally, as time goes by, once the corresponding surgery is completed, the operator only needs to remove the limb fixation device of this utility model, and then clean and disinfect it for the next cycle of use.

[0146] Finally, it should be noted that the above provides a detailed description of the present invention, and the principles of the present invention have been described herein. The explanation of the working principles above is only for the purpose of helping to understand the core idea of ​​the present invention. It should be pointed out that those skilled in the art can make improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
