Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-3 This utility model provides a technical solution: a bedside tracheotomy operating table, including an instrument placement table 3 and a cross frame 4 set at the bottom of the instrument placement table 3, and a support frame mechanism 1 that is synchronously adjusted in opposite directions is set on the cross frame 4.

[0031] The support frame mechanism 1 includes a first support frame 102 and a second support frame 106. The first support frame 102 and the second support frame 106 are disposed on both sides of the bottom of the cross frame 4. A first nut 103 is disposed on the first support frame 102, and a second nut 105 is disposed on the second support frame 106. The first nut 103 and the second nut 105 are symmetrically disposed and connected to a bidirectional ball screw 101. The bidirectional ball screw 101 is rotatably disposed in a groove 107. The groove 107 is disposed on one side of a storage groove, which is disposed at the bottom of the cross frame 4.

[0032] A plum blossom handwheel 108 is also provided on one side of the cross frame 4. One end of the plum blossom handwheel 108 is connected to the first bevel gear 109. The first bevel gear 109 meshes with the second bevel gear 110. The second bevel gear 110 is located on one side of the bidirectional ball screw 101. Through the transmission of the first bevel gear 109 and the second bevel gear 110, the rotation direction of the bidirectional ball screw 101 can be controlled.

[0033] First, rotate the plum blossom handwheel 108. The plum blossom handwheel 108 drives the first bevel gear 109 to rotate, the first bevel gear 109 drives the second bevel gear 110 to rotate, and the second bevel gear 110 drives the bidirectional ball screw 101 to rotate. The first nut 103 and the second nut 105 simultaneously drive the first support frame 102 and the second support frame 106 to move in opposite directions. The first support frame 102 and the second support frame 106 moving in opposite directions drive the two sets of support leg mechanisms 2 to move in opposite directions, so that the two sets of support leg mechanisms 2 move to the width of the mattress. Then, the two sets of support leg mechanisms 2 fix the device under the mattress, which can quickly set up the operating table and fix it under the mattress.

[0034] Furthermore, a limiting plate 104 is provided in the middle of the storage slot. The limiting plate 104 is flush with the crossbar 4. After the first support frame 102 and the second support frame 106 are stored, the storage position of the first support frame 102 and the second support frame 106 can be limited.

[0035] As a specific embodiment of this application, please refer to Figures 4-7 Both the first support frame 102 and the second support frame 106 are equipped with foldable support leg mechanisms 2. The support leg mechanism 2 includes a fixed foot 201, which is located on one side of the bottom of the first support frame 102 and the second support frame 106. A rotating shaft 204 is rotatably installed inside the fixed foot 201. An ear seat 211 is installed on the rotating shaft 204 and is connected to the upright frame 202. A positioning plate 203 is installed at the bottom of the upright frame 202, which can rotate the upright frame 202 and fix the upright frame 202 to the mattress of the hospital bed. An arc-shaped guide port 206 is provided on one side of the fixed foot 201, and a fixing port 208 is provided at one end of the arc-shaped guide port 206. A positioning pin 205 is engaged in the fixing port 208 to position the upright frame 202 after rotation.

[0036] The positioning pin 205 is movably mounted on the positioning rod 209, which is located on one side inside the upright 202. A return spring 210 is sleeved on the positioning rod 209, and one end of the return spring 210 is connected to the positioning pin 205, which can automatically engage the positioning pin 205 into the fixing port 208 and fix the upright 202.

[0037] First, the upright frame 202 is rotated, which drives the rotating shaft 204 to rotate via the ear seat 211. At the same time, the upright frame 202 drives the adjusting buckle 207 to move within the arc-shaped guide opening 206. At this time, the positioning pin 205 compresses the return spring 210. When the upright frame 202 rotates to the position where the first support frame 102 and the second support frame 106 are perpendicular, the return spring 210 drives the positioning pin 205 to move and engage the positioning pin 205 in the fixing opening 208. The positioning pin 205 fixes the upright frame 202. Then, the distance between the two sets of upright frames 202 is adjusted by the support frame mechanism 1. Then, the positioning plate 203 on the upright frame 202 is inserted into the gap between the mattress and the bed frame. Then, the support frame mechanism 1 drives the two sets of upright frames 202 to reset and move, and at the same time, the two sets of upright frames 202 are in contact with the side of the mattress, fixing the device to the bed frame. Then, the tracheotomy operation is performed using the surgical instruments on the instrument placement table 3.

[0038] Furthermore, an adjustment buckle 207 is provided on the other side of the positioning pin 205. The adjustment buckle 207 can move within the arc-shaped guide opening 206. When not in use, press the adjustment buckle 207, and the adjustment buckle 207 will drive the positioning pin 205 to move within the fixed opening 208. The positioning pin 205 moves to compress the return spring 210 and causes the positioning pin 205 to move out of the fixed opening 208. Then, the upright frame 202 is reset and rotated to fold and store the two sets of upright frames 202, making it easy to fold and store the upright frames 202.

[0039] Please see Figure 8 The instrument placement table 3 includes a contaminated tray 32 and an instrument placement tray 31. The instrument placement tray 31 is connected to the crossbar 4.

The limiting slider is slidably located in a limiting groove 33. The limiting groove 33 is located on the upper side of the instrument placement tray 31, which enables the instruments to be counted after the operation.

[0040] After the operating table is set up, push the contaminated placement tray 32. The contaminated placement tray 32 moves within the limiting groove 33 via the limiting slider, thereby unfolding the contaminated placement tray 32. Then, medical staff take the sterile instruments from the instrument placement tray 31 to perform the operation, and place the used instruments and waste into the contaminated placement tray 32. After the operation, the instruments can be quickly counted, and the waste can be easily cleaned.

[0041] Furthermore, the instrument placement tray 31 is also equipped with multiple sets of partitions 6 to facilitate the placement of cutting instruments of different specifications.

[0042] Furthermore, the contaminant placement tray 32 is also equipped with a detachable cover 5, which facilitates sealing of the contaminant placement tray 32 and achieves a dustproof effect.
