Among them, one end of the first bracket plate 301 and the second bracket plate 302 are movably hinged in the channel steel through a shaft rod, and the shaft rod used to connect the first bracket plate 301 and the second bracket plate 302 is rotated and connected to the upper and lower ends of the channel steel in a state of one up and one down in parallel, and the first bracket plate 301 and the second bracket plate 302 are interference-fitted on the shaft rod. After installation, the first bracket plate 301 and the second bracket plate 302 are in a crossed state.

[0047] In the above, a first hinge position 309 is provided between the two ends of the first bracket plate 301, and the first hinge position 309 is closer to one side of the channel steel. One end of the third bracket plate 303 is movably hinged to the first hinge position 309, and the other end is movably hinged to the end of the second bracket plate 302 away from the channel steel. One end of the fourth bracket plate 304 is movably hinged to the end of the first bracket plate 301 away from the channel steel, and the other end of the fourth bracket plate 304 is movably hinged to one end of the fifth bracket plate 305, and the other end of the fifth bracket plate 305 is hinged to the second bracket plate 302 and the third bracket plate 303 at the same point, so that the first bracket plate 301, the third bracket plate 303, the fourth bracket plate 304 and the fifth bracket plate 305 form a four-bar structure.

[0048] At the same time, one end of the sixth bracket plate 306 is hinged to the second bracket plate 302, the third bracket plate 303 and the fifth bracket plate 305 at the same point, and a second hinge position 310 is provided between the two ends of the sixth bracket plate 306; one end of the seventh bracket plate 307 is hinged to the first bracket plate 301 and the fourth bracket plate 304 at the same point, and a third hinge position 311 is provided between the two ends of the seventh bracket plate 307, the second hinge position 310 is hinged to the third hinge position 311, and the seventh bracket plate 307 The other end of the eighth bracket plate 308 is movably hinged to the fixing frame 2 of the thoracotomy component 4, one end of the eighth bracket plate 308 is hinged to the other end of the sixth bracket plate 306, the other end of the eighth bracket plate 308 is movably hinged to the fixing frame 2 of the thoracotomy component 4, and the length between the third hinge position 311 and one end connected to the thoracotomy component 4 is equal to the length of the eighth bracket plate 308, so that the sixth bracket plate 306, the seventh bracket plate 307, the eighth bracket plate 308 and the fixing frame 2 of the thoracotomy component 4 form another four-bar structure.

[0049] In the above, the fixing frame 2 of the thoracotomy component 4 is also a channel steel structure, and the seventh bracket plate 307 and the eighth bracket plate 308 are movably hinged to one side of the channel of the channel steel through an axle, the axle is fixedly arranged on the inner side of the channel steel of the thoracotomy component 4, and the seventh bracket plate 307 and the eighth bracket plate 308 are rotatably mounted on the axle.

[0050] from Figure 3 It can be seen that when the multi-link telescopic folding bracket 3 is in the extended state, the chest opening component 4 fixing frame 2 is in the horizontal state. Figure 4 It can be seen that when the multi-link telescopic folding bracket 3 is in the folded state, the fixing frame 2 of the chest-opening assembly 4 is in a vertical state and close to the channel steel, and the fixing frame 2 of the chest-opening assembly 4 is opposite to the notch of the channel steel, so that the multi-link telescopic folding bracket 3 can be stored. Of course, in order to increase the connection firmness between the fixing frame 2 of the chest-opening assembly 4 and the fixing bracket 1, the multi-link telescopic folding bracket 3 is set as at least two groups.

[0051] In one embodiment, in order to control the folding and unfolding state of the multi-link telescopic folding bracket 3, as shown in FIG. Figure 4 and Figure 5 As shown, a handle 5 for realizing the rotation of the second bracket plate 302 is provided on the channel steel, which can be understood as follows: one end of the shaft rod for fixing the second bracket plate 302 extends to the outside of the mounting frame 102 and is integrally formed with the handle 5. By rotating the shaft rod through the handle 5, the second bracket plate 302 can be driven to rotate, thereby linking the activities of other bracket plates to complete the state change of the multi-link telescopic folding bracket 3. Of course, in order to maintain the unfolded state of the multi-link telescopic folding bracket 3 during thoracotomy, as shown in FIG. Figure 5As shown, a slot is provided on the handle 5, a sleeve is provided on the base 101, and a spring cone head pin 6 is installed in the sleeve. When the handle 5 is turned to make the multi-link telescopic folding bracket 3 in a fully expanded state, the slot is located at the top of the spring cone head pin 6, and the spring cone head pin 6 pops up and snaps into the slot, thereby fixing the handle 5 to prevent arbitrary rotation, so as to ensure that the multi-link telescopic folding bracket 3 is in a fully expanded state during the operation, and keep the thoracotomy assembly 4 fixing frame 2 in a horizontal state.

[0052] In this embodiment, the thoracotomy component 4 includes an external support power unit and an external support clamp 405. The external support power unit is arranged on the fixed frame 2 of the thoracotomy component 4. A pair of the external support clamps are transmission-connected to the external support power unit through a telescopic rod 406. The external support clamp 405 is driven by the external support power unit to move in the same direction and reverse direction.

[0053] Specifically, if Figure 1 As shown, the external support power unit includes a screw rod 401 and a polished rod 402. A seat body is provided on the front surface of the fixing frame 2 of the thoracotomy component 4. The screw rod 401 is rotatably installed between the seat bodies through a bearing, and a knob 404 is provided at one end of the screw rod 401. The screw rod 401 can be rotated by the knob 404. The polished rod 402 is arranged between the seat bodies parallel to the screw rod 401. The screw rod 401 is symmetrically provided with threads in opposite directions at its midpoint. Slide blocks 403 are arranged on the threads at both ends. The slide blocks 403 are slidably provided on the polished rod 402. Therefore, by rotating the screw rod 401 with the knob 404, the slide blocks 403 can realize the same direction and reverse movement.

[0054] Further, such as Figure 1As shown, the external support fixture 405 includes a connecting rod 4051, a fixed hook 4052 and a movable hook 4053, wherein the fixed hook 4052 is integrally formed at the bottom of the connecting rod 4051, and a sleeve 4057 is integrally formed at one end of the connecting rod 4051 away from the fixed hook 4052, and a pin hole is arranged in the sleeve 4057, one end of the telescopic rod 406 is horizontally fixed to the slider 403 along a direction perpendicular to the long axis of the fixing frame 2 of the thoracotomy component 4, and a spring round head pin is arranged at the other end of the telescopic rod 406, and the telescopic rod 406 is inserted into the sleeve 4057, and the detachable connection between the external support fixture 405 and the telescopic rod 406 is completed by the spring round head pin being inserted into the pin hole. After the external support assembly is arranged between the telescopic rod 406 and the external support driving unit, when performing a thoracotomy, the fixed bracket 1 is fixed to the operating table, the fixed bracket 1 is located on the side of the head and neck, and the telescopic rod 406 is stretched so that the thoracotomy assembly 4 is located above the chest cavity, thereby forming an open space between the thoracotomy assembly 4 fixed frame 2 and the telescopic rod 406, which is convenient for performing the operation. It can be understood that the external support clamp 405 is a device that needs to contact the surgical incision when performing a thoracotomy. By adopting a detachable structure to set the external support clamp 405, when the thoracotomy is not in use, the external support clamp 405 can be removed and sterilized for sterile storage, and it also further releases space for the storage of the thoracotomy, which is convenient for storage. Similarly, the connection structure between the external support driving unit and the external support clamp 405 is designed as a telescopic rod 406, which is also for the purpose of achieving convenient storage.

[0055] In addition, in the above, a plurality of detachable movable hooks 4053 are provided on both sides of the fixed hook 4052, specifically, as Figure 6 As shown, first countersunk holes 4054 are provided on both sides of the fixed hook 4052, a first magnet block is provided in the first countersunk hole 4054, a boss 4055 is provided on one side of the movable hook 4053 to be inserted into the first countersunk hole 4054, a second magnet block is provided on the boss 4055 to be attracted to the first magnet block, a second countersunk hole 4056 is provided on the other side of the movable hook 4053 to be matched with the boss 4055, and a third magnet block is provided in the second countersunk hole 4056 to be attracted to the second magnet block. It is not difficult to imagine that, according to actual needs, multiple movable hooks 4053 can be installed on both sides of the fixed hook 4052, so as to realize external support of chest cavities of different sizes, which is very convenient.

[0056] It can be seen that the method of using a thoracotomy device for thoracic surgery provided in the embodiment of the present application is:

[0057] First, fix the fixing bracket 1 to both sides of the operating table through the clamping part 103, and the fixing bracket 1 is close to the head and neck;

[0058] Next, the multi-link telescopic folding bracket 3 is opened by turning the handle 5, and the chest opening assembly 4 fixing frame 2 is flipped to a horizontal state. At this time, the spring cone head pin 6 is inserted into the slot, locking the handle 5 to prevent it from rotating at will;

[0059] Then, the telescopic rod 406 is extended, and the external support clamp 405 is taken out and assembled on the telescopic rod 406, and at the same time, it is considered whether to add an appropriate amount of movable hooks 4053 to adapt to the chest cavity size;

[0060] Finally, the screw rod 401 is rotated by the knob 404 to drive the outer support clamp 405 to move to both sides to open the skin component.

[0061] After the operation is completed, the used external support clamp 405 is removed, the telescopic rod 406 is recovered, and the handle 5 is turned to shrink and fold the multi-link telescopic folding bracket 3 for easy storage.

[0062] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
