Abstract
Description
Technical Field
[0001] This utility model relates to the field of traction frame technology, specifically a surgical bed clamp-type shoulder arthroscopy traction frame. Background Technology
[0002] Shoulder arthroscopy is widely used in the diagnosis and treatment of shoulder joint diseases due to its minimally invasive and precise characteristics. However, due to the unique anatomy of the shoulder joint, patients usually need to be placed in a lateral decubitus position during the operation, and appropriate traction is applied to the shoulder joint to open the joint cavity and create a clear surgical field to facilitate the operation. In this position, the traction angle and traction force of the patient's upper limb are particularly important to maintain specific positions such as 20° of extension, 45° of abduction, and 10° of flexion.
[0003] Traditional traction devices have many shortcomings. For example, traction frames are fixed on one side of the operating table by inserting a rod into a clamp, resulting in poor stability, easy wobbling, and significant damage to the side rails of the operating table. Furthermore, the traction frame is a single unit, occupying a large amount of space when not in use, and adjusting its orientation requires overall adjustment, which is inconvenient. Standing traction frames, on the other hand, suffer from poor stability, heavy chassis, inconvenient movement, and excessive storage space requirements. Traditional traction frames often use sandbags or water bags as force carriers, making it difficult to precisely control the traction force applied to the shoulder joint, potentially leading to over-traction and injury.
[0004] Therefore, we propose a surgical table-clamped shoulder arthroscopic traction frame to address the problems mentioned above.
[0005] The information disclosed above in this background section is only for enhancing the understanding of the background section of this invention, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0022] Example 1
[0023] Please see Figure 1 A surgical table clamp-type shoulder arthroscopic traction frame, comprising:
[0024] The base 1 includes a support seat 11, with movable sleeves 12 sleeved at both ends of the support seat 11. A connector 14 is installed at the bottom end of the movable sleeve 12. An installation seat 2 is provided on the upper surface of the support seat 11. An insertion rod 3 is inserted into the installation seat 2. A support rod 4 is installed on the insertion rod 3. A rotating rod 6 is rotatably connected to the top end of the support rod 4. A deflector 8 is provided on the rotating rod 6. A traction member 9 is provided on the deflector 8.
[0025] Please see Figure 1 and Figure 3 The support base 11 and the mounting base 2 have a "T" shaped structure. The movable sleeve 12 is slidably connected to the support base 11. Tension springs 13 are fixedly installed at both ends of the support base 11. The other end of the tension spring 13 is fixedly connected to the movable sleeve 12, so that the two movable sleeves 12 are clamped towards the support base 11 in the normal state. The mounting base 2 is an octagonal sleeve or other sleeves that can play the same role. The insertion rod 3 is an octagonal insertion rod that is compatible with the mounting base 2.
[0026] In use, the connector 14 of the movable sleeve 12 can be inserted into a hospital-standard clamp for fixation. The insertion rod 3 is directly inserted into the mounting base 2. The double-sided fixation greatly increases stability. At the same time, the orientation of the rotating rod 6 can be easily adjusted by rotating the angle of the insertion rod 3 as needed. The support rod 4 is used to install the rotating rod 6. One end of the rotating rod 6 is rotatably connected to the support rod 4. The connection between the rotating rod 6 and the support rod 4 is interference-fitted. The other end of the rotating rod 6 extends out. The deflector 8 is set on the rotating rod 6 to change the direction of the rope of the traction component 9. By setting the support base 11 and two movable sleeves 12, the operating table can be clamped from both sides of the operating table using the connector 14, thereby increasing the overall stability of the device. By setting the mounting base 2 and the insertion rod 3, the device is separated into two parts, which reduces the space occupied when not in use, facilitates installation when in use, and allows for easy adjustment of the orientation of the device.
[0027] Example 2
[0028] Please see Figure 1 and Figure 2 A rotating seat 5 is fixedly installed at the top of the support rod 4. A rotating rod 6 is rotatably connected to the inner wall of the rotating seat 5. The rotation center between the rotating rod 6 and the rotating seat 5 is located at the tail of the rotating rod 6. Mounting grooves 7 are opened at both ends of the rotating rod 6. The deflector 8 is installed in the mounting groove 7. The mounting groove 7 is a through groove.
[0029] The rotating seat 5 is used to install the rotating rod 6. The rotating seat 5 is equipped with a rotating shaft. The rotating rod 6 is rotatably connected to the rotating shaft and is interference-fitted. The rotating rod 6 can maintain its own angle when no large external force is applied. The mounting groove 7 is used to install the deflector 8, and also allows the traction component 9 to pass through the mounting groove 7.
[0030] Please see Figure 2 The deflector 8 is a movable pulley, which is installed in the mounting groove 7 and is rotatably connected to the rotating rod 6. The traction component 9 includes a traction rope 91 installed on the deflector 8. A hand crank 92 is installed on the surface of the support rod 4. One end of the traction rope 91 is connected to the hand crank 92, and the other end of the traction rope 91 hangs down from the top of the rotating rod 6 through the deflector 8. A pull ring 93 is provided at the end of the traction rope 91 away from the hand crank 92.
[0031] The mounting slot 7 is provided at both ends of the rotating rod 6, so there are two movable pulleys. The two movable pulleys are on the same plane. The traction rope 91 passes through the two movable pulleys. The hand crank 92 is a commonly used hand crank with a self-locking function. This device is a common technology and will not be described in detail here. By rotating the hand crank 92, the traction rope 91 can be retracted or released. The pull ring 93 at the top of the traction rope 91 is hooked on the traction device of the patient's shoulder joint. By rotating the hand crank 92, the retraction and release of the traction rope 91 are controlled, thereby controlling the traction force on the patient's shoulder joint.
[0032] Please see Figure 1 and Figure 4 The traction rope 91 is equipped with a pull ring 93 at one end, which is also connected to a tension gauge 10. Both ends of the tension gauge 10 are equipped with pull rings 93.
[0033] By installing a force gauge 10 at the pull ring 93 of the traction rope 91, and then connecting the force gauge 10 to the traction device of the patient's shoulder joint, the force applied to the shoulder joint can be monitored in real time during traction, thus preventing over-traction and injury to the patient's shoulder joint.
