[0025] The following further describes the present utility model in conjunction with the Figures 1-5 accompanying drawings.

[0026] In order to solve the problems existing in the background art, the present application proposes the following technical solution: a fixing device for thoracic surgery.

[0027] In the specific technical solution, it includes a first fixing plate 1, a plurality of elastic bands 4, and a plurality of length-adjusting and tightening components 3. A plurality of mounting grooves 2 are provided on both sides of the first fixing plate 1. Two shoulder straps 5 are fixed above the first fixing plate 1. A second fixing plate 6 is fixed between one ends of the two shoulder straps 5. A plurality of grooves 7 are provided on both sides of the second fixing plate 6. The number of mounting grooves 2 on both sides of the first fixing plate 1 is opposite to the number of grooves 7 on both sides of the second fixing plate 6. A fixing strip 8 is fixed to one side of the elastic band 4. The fixing strip 8 is fixed inside the groove 7 by a plurality of screws. As Figure 1 shown, taking the example that three mounting grooves 2 are respectively provided on both sides of the first fixing plate 1, the number of elastic bands 4 and the length-adjusting and tightening components 3 corresponds to the number of mounting grooves 2, and the elastic bands 4 are located on both sides of the first fixing plate 1, and are used to connect the first fixing plate 1 and the second fixing plate 6, and determine the distance between the first fixing plate 1 and the second fixing plate 6.

[0028] A plurality of length-adjusting and tightening components 3 are respectively arranged inside a plurality of installation grooves 2. The length-adjusting and tightening components 3 are used to adjust the length and tightness of the elastic band 4, so as to change the distance between the first fixing plate 1 and the second fixing plate 6. This can not only improve the comfort and applicable range for patients, but also extend the service life of the elastic band 4 with reduced elasticity and reduce the replacement frequency of the elastic band 4. The length-adjusting and tightening component 3 includes an adjusting member. The adjusting member includes a fixing shell 31 which is fixed inside the installation groove 2. An adjusting knob 32 is rotatably arranged on the top of the fixing shell 31. A hidden shell is arranged around the adjusting knob 32, and the top of the hidden shell is rotatably arranged on the top of the inner wall of the installation groove 2 without interfering with the normal rotation of the adjusting knob 32. And anti-slip lines are arranged on the outside of the adjusting knob 32 to increase the contact friction between the hand and the adjusting knob 32. An arrow indication is arranged on the fixing shell 31, and the word "out" is marked in the arrow direction to facilitate knowing the adjustment effect that can be obtained by the rotation direction. A bevel gear disk 33 is rotatably arranged on the top of the inner wall of the fixing shell 31. The adjusting knob 32 and the bevel gear disk 33 are fixedly connected by a short shaft. A limiting strip 34 is slidably arranged inside the fixing shell 31. A first spring 36 is fixed to the bottom of the limiting strip 34. The first spring 36 functions to automatically snap the locking plate 37 into the inside of the bevel teeth to automatically lock the bevel gear disk 33. A locking plate 37 is rotatably arranged on one side of the L-shaped fixing plate 35. One end of the first spring 36 is fixed to one side of the locking plate 37. A positioning screw 38 is threadedly installed above the fixing shell 31 through a support piece. A threaded hole is formed in the limiting strip 34. When the locking plate 37 is inside the bevel teeth, the threaded hole formed in the limiting strip 34 is aligned with one end of the positioning screw 38. The cooperation between the positioning screw 38 and the threaded hole can limit the locking plate 37 and the L-shaped fixing plate 35. The elastic band 4 is arranged inside the fixing shell 31.

[0029] The length adjustment and tightening assembly 3 also includes a disassembly component, which is convenient for quickly replacing the elastic band 4 with severe elastic failure. The disassembly component is arranged inside the fixed shell 31, and the disassembly component is used to quickly replace the elastic band 4 that has lost its elasticity. The disassembly component includes two square hole seats 39 fixed inside the fixed shell 31 and a cover plate 310 hinged to the outside of the fixed shell 31. The cover plate 310 is fixed and closed with a small stud and the fixed shell 31. The two square hole seats 39 are fixed with a positioning card plate on the opposite side, and the positioning card plate is U-shaped. A winding rod 311 is arranged between the two square hole seats 39. The elastic band 4 is wrapped around the outside of the winding rod 311. Hollow shells 312 are fixed at both ends of the winding rod 311. Two alignment cards are placed in the two hollow shells 312 respectively. When the plate is on the inside, the clamping column 314 and the square hole of the square hole seat 39 are aligned, and the outside of the two hollow shells 312 are provided with vertical grooves 313. The inside of the two hollow shells 312 are slid with a clamping column 314, and one end of the clamping column 314 extends to the inside of the square hole seat 39. A second spring 315 is fixed to one end of the clamping column 314. The second spring 315 plays a role in automatically pulling the clamping column 314 into the square hole of the square hole seat 39. The outside of the clamping column 314 and the outside of the hollow shell 312 are both fixed with a booster rod 316. The booster rod 316 located on the clamping column 314 facilitates pulling the clamping column 314 to slide in the vertical groove 313, and the booster rod 316 fixed on the hollow shell 312 plays a role in assisting the other booster rod 316.

[0030] In order for those skilled in the art to fully understand the technical solution, this application makes the following overall summary:

[0031] When in use, the fixing device is put on the patient's head so that the patient's head is between the two shoulder straps 5, and the first fixing plate 1 and the second fixing plate 6 are respectively on the patient's chest and back. If the elastic band 4 is too tight or short for the patient, the adjusting button 32 can be turned to rotate the helical gear wheel disc 33 in the direction of the arrow marked thereon. During the rotation of the helical gear wheel disc 33, the locking plate 37 will be automatically pushed to deflect out of the inner side of the helical teeth, and the locking plate 37 squeezes the first spring 36. Under the reaction force of the first spring 36, the locking plate 37 can automatically snap into the inner side of the helical teeth to automatically fix it after the helical gear wheel disc 33 stops rotating, preventing the helical gear wheel disc 33 from rotating. The rotation of the helical gear wheel disc 33 drives the winding rod 311 to rotate through the clamping column 314 clamped with the square hole seat 39, and the winding rod 311 releases a section of the wound elastic band 4 until the elastic band 4 is suitable for comfortable and normal use by the patient.

[0032] On the contrary, if the elastic band 4 is too loose or too long for the patient, the positioning screw 38 can be first screwed out of the screw hole on the limiting strip 34 to release the limitation of the limiting strip 34 and the L-shaped fixing plate 35. At this time, the L-shaped fixing plate 35 will drop under the action of gravity, and the locking plate 37 will fall out of the inner side of the helical teeth. At this time, without the locking of the helical gear wheel 33, the helical gear wheel 33 can be rotated in the opposite direction of the arrow marked with words, driving the winding rod 311 to wind the elastic band 4 back into the fixed shell 31. After adjusting to a length suitable for the patient to use, pull the limiting strip 34 upward to drive the L-shaped fixing plate 35 and the locking plate 37 upward. At the same time, the adjusting knob 32 can be appropriately rotated to drive the inner side of the helical teeth of the helical gear wheel 33 to correspond to the locking plate 37 so that the locking plate 37 can be inserted. Subsequently, the position of the locking plate 37 can be fixed by screwing the positioning screw 38 into the screw hole. The length of the elastic band 4 can be adjusted according to the patient's body shape to change the distance between the first fixing plate 1 and the second fixing plate 6, increasing the comfort of the patient during use, expanding the applicable range of the device, and it can also be adjusted for normal use after the elasticity of the elastic band 4 decreases, without frequently replacing the elastic band 4, reducing the replacement frequency of the elastic band 4.

[0033] If the elastic band 4 fails severely in elasticity, the cover plate 310 can be opened. Hold the two assisting rods 316 on the two hollow shells 312 with both hands respectively. The assisting rods 316 on the clamping posts 314 will drive the clamping posts 314 to squeeze the second spring 315 out of the square hole seat 39, and then the winding rod 311 can be taken out of the fixed shell 31. The fixing strip 8 on the second fixing plate 6 where the elastic band 4 is installed can be removed to remove the elastic band 4. The winding rod 311 with the new elastic band 4 installed is installed between the two square hole seats 39 by using the clamping posts 314, the cover plate 310 is covered, and the fixing strip 8 is fixed in the groove 7 by screws to complete the replacement of the elastic band 4.

[0034] The standard parts used in the present utility model can all be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The machines, parts, and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here.
