Description

Technical Field

[0001] This utility model relates to the field of traction device technology, specifically to a traction frame for shoulder arthroscopic surgery. Background Technology

[0002] Shoulder arthroscopy is a minimally invasive surgical procedure for treating joint diseases. An optical lens is placed in front of the arthroscope, which is inserted into the joint through a surgical incision of about 0.5 cm. An image converter displays the captured images inside the joint on a television screen. Extended surgical instruments are then inserted into the joint through several other surgical incisions of about 0.5 cm. Under direct visualization with the arthroscope, the damaged tissue is repaired, reconstructed, removed, or excised. Due to its advantages of being minimally invasive, intuitive, and causing minimal damage, it has become an important technique in shoulder joint surgery, reflecting the trend towards minimally invasive and precise surgical techniques.

[0003] In shoulder arthroscopic surgery, in order to obtain a good surgical field and facilitate surgical operation, it is often necessary to use an upper limb traction device to pull the patient's upper limb upward. The quality of the traction device has a significant impact on the operation. Currently, some existing traction devices have many problems. For example, some traction devices that are fixed to the operating table or wall have poor flexibility in practical application. In addition, some traction devices are inconvenient to adjust, which can easily affect the efficiency of the operation. Utility Model Content

[0004] To address the aforementioned problems, this utility model aims to provide a traction frame for shoulder arthroscopy surgery. By designing a sliding adjustment component, the traction belt can be adjusted by using a slider and telescopic rod structure to drive the rollers on both sides, thereby tractioning the patient's upper limb to different heights. Combined with a sliding and height-adjustable main support, it can improve flexibility in practical applications and has the advantages of being easy to use, having good stability, high flexibility, and simple structure.

[0005] The main idea of ​​the technical solution adopted by this utility model is to design a sliding adjustment component. By setting a slider and a fixed frame on the top of the main support, and symmetrically setting an adjusting slide rod and a connecting rod that are rotatably connected between the slider and the fixed frame, the slider can be used to adjust the multiple rollers on the connecting rod and the fixed frame. The traction height of the patient's upper limb can be adjusted by adjusting the traction belt sleeved on the rollers.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A traction frame for shoulder arthroscopy includes a movable main support, the top of which is provided with a traction strap for traction of the patient's upper limb during shoulder arthroscopy, and the top of which is provided with a sliding adjustment component for adjusting the traction strap.

[0008] The sliding adjustment assembly includes a slider that is slidably mounted on the main support. Adjusting slide rods are fixed on both sides of the slider. A fixing frame is also provided on the top of the main support. Two connecting rods are rotatably mounted on both sides of the fixing frame. The end of each adjusting slide rod away from the slider is rotatably connected to the connecting rod on the same side. Rollers are provided on the top of the fixing frame and the end of the connecting rod away from the fixing frame. A traction belt is sleeved on multiple rollers.

[0009] Based on the above technical solution, the slider is further provided with a slider locking bolt, the adjusting slide rod is provided with an adjusting slide rod locking bolt, and the fixing frame is provided with a fixing frame locking bolt.

[0010] Based on the above technical solution, further, one end of the traction belt is provided with an upper limb strap for fixing the patient's upper limb, and the other end of the traction belt is provided with a buckle for connecting with a heavy object.

[0011] Based on the above technical solution, the main support includes a base, a plurality of lockable casters are provided below the base, a support slide rod is fixed at the center of the base, and a top rod for mounting the slider and the fixing frame is fixed at the top of the support slide rod.

[0012] Based on the above technical solution, the support slide rod is further provided with a support slide rod locking bolt.

[0013] The beneficial effects of this utility model are:

[0014] 1. By designing a sliding adjustment component, the slider can be slid up and down along the main support, and the angle of the connecting rods on both sides can be adjusted by the adjustment rod, thereby adjusting the traction angle of the traction belt on the rollers sleeved on the connecting rods. This makes the present invention convenient to use.

[0015] 2. By setting slider locking bolts on the slider, adjusting slide rod locking bolts on the adjusting slide rod, fixing frame locking bolts on the fixing frame, and supporting slide rod locking bolts on the supporting slide rod, the moving structures in this traction frame are locked to ensure the traction stability of the support frame during surgery.

[0016] 3. By setting multiple lockable casters under the main support, the casters can be locked during surgery to maintain the overall stability of the traction frame, or the casters can be unlocked to move the entire traction frame, making the device highly flexible. In addition, the overall structure of this utility model is simple, and each structure is easy to disassemble and replace. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] The inventors discovered that in shoulder arthroscopy, in order to obtain a good surgical field and facilitate surgical operation, it is often necessary to use an upper limb traction device to pull the patient's upper limb upward. However, some existing traction devices have many problems. For example, some traction devices that are fixed to the operating table or wall have poor flexibility in practical application. In addition, some traction devices are inconvenient to adjust, which can easily affect the efficiency of the operation.

[0027] Based on the above findings, this application proposes a traction frame for shoulder arthroscopy. By designing a sliding adjustment assembly, a slider and a fixing frame are installed on the top rod at the top of the main support. Adjusting rods and connecting rods, symmetrically arranged and rotatably connected between the slider and the fixing frame, are used to adjust the traction belt fitted onto the rollers by sliding the slider relative to multiple rollers on the connecting rod and the fixing frame. Multiple locking bolts are used to lock the adjustment points between the various structures to ensure the stability of traction during surgery. This design offers advantages such as ease of use, good stability, high flexibility, and simple structure.

[0028] See Figure 1 , Figure 2 This application discloses a traction frame for shoulder arthroscopy, including a main support 1, see reference. Figure 6 In some implementations, the main support 1 includes a base 101 with multiple casters 102 below. The base 101 is made of a high-strength metal material. The casters 102 facilitate the movement of the traction frame as a whole. The casters 102 can be locked when the traction frame is used to traction the patient's upper limb to fix the main support 1 on the ground and prevent the traction frame from slipping and affecting the traction effect.

[0029] In some implementations, a downwardly recessed threaded hole is provided at the upper center of the base 101, and an external thread that mates with the threaded hole is provided at the bottom end of the support slide rod 103. The support slide rod 103 can be fixed to the base 101 by the threaded engagement. The support slide rod 103 is a metal rod with high strength. When using this traction frame to traction the patient's shoulder joint, the height of the traction frame can be adjusted by adjusting the length of the support slide rod 103. After adjustment, the length of the support slide rod 103 can be locked using the support slide rod locking bolt 105 to ensure the stability of the traction frame during traction. The support slide rod 103 is vertically set, and a cuboid top rod 104 is fixed to the top of its upper movable end by threaded connection or welding. The top rod 104 is a two-section cuboid rod, and the cross-sectional area of ​​its lower section is larger than that of its upper section.

[0030] The top of the main support 1 is provided with a sliding adjustment component 3 for adjusting the traction belt 2, see reference. Figure 3 , Figure 4 as well as Figure 5 The sliding adjustment assembly 3 includes a slider 301 that is slidably mounted on the main support 1, i.e., slidably mounted on the lower section of the top rod 104. In some embodiments, the slider 301 is a cuboid structure with a cuboid through hole in its middle that matches the lower section of the top rod 104. The entire slider is made of metal. Adjusting slide rods 302 are laterally fixed on both sides of the slider 301 by welding or other means. The adjusting slide rods 302 are made of high-strength metal. The fixed end and the movable end are tightly fitted together. The fixed end is fixed to the side of the slider 301, and a set of symmetrical rotating shafts are fixed at the farthest point of the movable end.

[0031] A fixing bracket 303 is fixed to the upper section of the top rod 104 by a plug-in connection. (See reference) Figure 7 The fixing frame 303 is a symmetrical frame structure with a through hole at the bottom that matches the upper section of the top rod 104. The fixing frame 303 has through holes at both ends and is located in the through holes on both sides. A set of symmetrical connecting rods 304 are rotatably arranged by inserting a rotating shaft. Each connecting rod 304 has a cavity structure near the middle and a through hole that can be engaged by the rotating shaft at the movable end of the adjusting slide rod 302. When the slider 301 slides up and down along the top rod 104, the two connecting rods 304 can be driven to rotate synchronously up or down through the adjusting slide rods 302 on both sides.

[0032] Meanwhile, the two connecting rods 304 have through holes at the ends away from the fixing frame 303, and rotatable rollers 305 are installed in the through holes. In addition, rollers 305 of the same specifications are installed on the top of the fixing frame 303. Each roller 305 has an inwardly recessed groove structure on its end face. A traction belt 2 is nested in the groove structure on each roller 305. That is, one side of the roller 305 can drive the other side and the roller 305 on the fixing frame 303 to rotate through the traction belt 2. In some embodiments, upper limb straps 4 for fixing the patient's upper limb and buckles 5 for connecting heavy objects are fixed at both ends of the traction belt 2.

[0033] In use, this utility model uses a buckle 5 to connect to a heavy object, such as a kettlebell, placed on the ground, and the other end of the upper limb strap 4 is fixed to the patient's upper limb. At this time, the height of the slider 301 can be adjusted to drive the connecting rods 304 on both sides to rotate upward. Then, through the pulley structure formed by the three rollers 305, the patient's upper limb is raised to the required height for shoulder arthroscopy. After adjustment, the slider 301 is fixed relative to the lower section of the top rod 104 using the slider locking bolt 306, and the adjusting sliders 302 on both sides are fixed using the adjusting slider locking bolt 307. Alternatively, the fixing frame 303 can be fixed relative to the upper section of the top rod 104 using the fixing frame locking bolt 308, thereby locking the entire sliding adjustment assembly 3 so that the traction frame can provide stable traction for the patient's upper limb, so that the surgery can be performed smoothly.

[0034] In some implementations, the support slide bar 103 in the main support 1 can be replaced with an electric push rod structure to adjust the overall height of the traction frame; or multiple electric push rod structures that can push the slider 301 upward can be vertically installed on the top rod 104 to slide the slider 301 along the top rod 104, thereby facilitating the adjustment of the traction height of the patient's upper limb.

[0035] Specific application examples

[0036] Move the main support 1 to one side of the operating table and lock the universal caster 102 at the bottom. Then, pre-adjust the overall height of the main support 1 according to the height of the patient lying flat on the operating table. After the adjustment is completed, tighten the support slide rod locking bolt 105 on the support slide rod 103 to fix the main support 1 as a whole.

[0037] The upper limb strap 4 at one end of the traction strap 2 is used to fix the upper limb on the side of the shoulder joint required for the patient's surgery, and the other end is fixed to a weight on the ground by a buckle 5.

[0038] Depending on the height to which the patient's upper limb is lifted by a heavy object, the slider 301 is slid up or down along the top rod 104 to adjust the height so that the patient's upper limb reaches the height required for shoulder arthroscopy. After adjustment, the slider 301 is locked relative to the top rod 104 using the slider locking bolt 306, and the adjusting sliders 302 on both sides are locked using the adjusting slider locking bolt 307 to ensure the overall traction stability of the traction frame. Then, the patient undergoes shoulder arthroscopy.
