[0006] Furthermore, a smooth slot for plugging is provided at one end of the fixing rod, and a threaded hole is provided at the other end. The smooth slot and the threaded hole are symmetrically arranged about the middle of the fixing rod, and a pin is threadedly connected inside the threaded hole.

[0007] Furthermore, the latch is slidably connected with a block away from the threaded connection end of the threaded hole, a spring is fixed to the latch end, the other end of the spring is fixed inside the latch, the smooth slot is connected with a through slot, and the block is clamped inside the through slot.

[0008] Furthermore, the fixing rod is provided with a groove, the interior of the groove is slidably connected with a sliding block, and the sliding block is fixed to the lifting ring at an end away from the groove.

[0009] Furthermore, a locking screw is threadedly connected to the sliding block, and the locking screw contacts the surface of the groove after being screwed in.

[0010] The beneficial effects of the utility model are: the arm is fixed by a fixing rod, which replaces the traditional method of winding multiple layers of gauze to connect the arm to the traction fixation frame, and at the same time, the two fixing rods can be plugged and connected, so that a suitable number of fixing rods can be installed according to the different arm lengths of different patients, and the fixing rod and the arm are fixed by cross-sticking gauze belts, and the cross-sticking method can be adjusted according to the different arm circumferences, and each fixing rod is located at a different position on the arm, so the setting method of the gauze belt is flexible, so that the arm fixation can be completed efficiently, which is convenient for doctors to operate and improves the efficiency of shoulder arthroscopy.

[0015] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0016] Please also refer to Figures 1 to 3 The shoulder arthroscopy surgery traction arm fixing structure of the utility model embodiment will be described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 As shown, the shoulder arthroscopy surgery traction arm fixing structure includes a fixing rod 1, and the fixing rod 1 is provided with a plurality of fixing rods 1, and the plurality of fixing rods 1 are plugged in and connected end to end, and one side of the fixing rod 1 is arranged in an arc shape, and gauze strips 2 are bonded on both sides of each fixing rod 1, and Velcro public patches 3 are sewn on the ends of the gauze strips 2 away from the fixing rod 1, and the positions of the Velcro public patches 3 sewn by the two gauze strips 2 are opposite, and the two gauze strips 2 on each fixing rod 1 are cross-bonded through the two Velcro public patches 3, and a hanging ring 4 is slidably connected to the fixing rod 1.

[0018] In this embodiment, a plurality of fixing rods 1 and gauze strips 2 on the sides of the fixing rods 1 are used to form a multi-joint structure. Each gauze is sewn with Velcro at the end away from the fixing rod 1. Two gauze strips 2 can be cross-pasted at the end away from the fixing rod 1, with the outer side of one gauze strip 2 pasted on the inner side of the other gauze strip 2. The length of the fixing rod 1 is 10 cm, and the material is made of silicone plate.

[0019] As an implementation mode, a smooth slot 5 for plugging is provided at one end of the fixing rod 1, and a threaded hole 6 is provided at the other end. The smooth slot 5 and the threaded hole 6 are symmetrically arranged about the middle of the fixing rod 1, and a pin 7 is threadedly connected inside the threaded hole 6.

[0020] Among them, the surface of the end of the pin 7 away from the threaded connection with the threaded hole 6 is smooth. A smooth slot 5 for plug-in is provided at one end of the fixing rod 1, and a threaded hole 6 is provided at the other end. The smooth slot 5 and the threaded hole 6 are symmetrically arranged about the middle part of the fixing rod 1, and the pin 7 is threadedly connected inside the threaded hole 6.

[0021] The latch 7 is slidably connected with a block 8 away from the threaded connection end with the threaded hole 6, and a spring 9 is fixed to the end of the block 8 facing the latch 7. The other end of the spring 9 is fixed inside the latch 7. The smooth slot 5 is connected with a through slot 10, and the block 8 is clamped inside the through slot 10, wherein the block 8 is wedge-shaped.

[0022] When installing multiple fixing rods 1, firstly, thread the pin 7 into the threaded hole 6 on the fixing rod 1. After the pin 7 is fixed, the end of the plug-in connection block 8 is inserted into the smooth slot 5. When the block 8 is inserted, it slides into the pin 7 as the spring 9 contracts. When the pin 7 is inserted into the bottom of the smooth slot 5, the block 8 pushes out along the through slot 10 after the spring 9 is reset, so that the two fixing rods 1 are fixed.

[0023] As an implementation manner, a groove 11 is provided on the fixing rod 1 , a sliding block 12 is slidably connected inside the groove 11 , and the sliding block 12 is fixed to the lifting ring 4 at the end away from the groove 11 .
