In medical treatment, thoracic surgery is a medical specialty that mainly specializes in the study of organs in the chest cavity. Medical staff need to use a thoracotomy when performing thoracic surgery. The thoracotomy is an auxiliary device that mainly expands the ribs to facilitate surgical treatment by medical staff.

[0003] A thoracotomy is an instrument used to open the ribs to present a surgical field of view during thoracotomy. Currently, some thoracotomies are generally directly clamped on the patient's ribs, and completely rely on the bonding force of the movable connection structure between the movable support rods and the cross rails to support the ribs. The patient's ribs are always used as the force point. Under long-term contact during surgery, the patient's ribs are easily damaged, so this needs to be solved. Utility Model Content

[0034] In this embodiment, when in use, the support frame 1 is placed on the edge of the operating table. When the medical staff rotates the bolt 202 inside the trapezoidal groove 201, the trapezoidal block 102 on the outer surface of the bolt 202 is driven to move, so that the movable plate 101 on the surface of the support frame 1 and the mounting seat 2 are installed on the surface of the operating table, and then the threaded rod 105 inside the long groove 103 is rotated to drive the cross bar 106 on the outer surface of the threaded rod 105 to adjust the height. At the same time, the end of the cross bar 106 away from the threaded rod 105 is movably embedded with a guide rod 104, which is fixedly installed on the inner wall of the long groove 103 through the guide rod 104, so that the position of the cross bar 106 is limited when it moves. By adjusting the height of the cross bar 106, when performing thoracotomy on different patients, it can be adjusted to the corresponding height, thereby improving the applicability of the device. At the same time, the overall device is installed on the surface of the support frame 1, which reduces the force applied to the patient's ribs and reduces the harm to the patient.

At the same time, the end of the cross bar 106 away from the threaded rod 105 is movably embedded with a guide rod 104, which is fixedly installed on the inner wall of the long groove 103 through the guide rod 104, so that the position of the cross bar 106 is limited when moving. By adjusting the height of the cross bar 106, when performing thoracotomy on different patients, it can be adjusted to the corresponding height, thereby improving the applicability of the device. At the same time, the overall device is installed on the surface of the support frame 1 to reduce the force applied to the patient's ribs and reduce damage to the patient. At the same time, a connecting block 3 is slidably embedded on the surface of the cross bar 106. When the limiting plate 302 is pulled, the spring 301 on one side of the limiting plate 302 is connected to the surface of the connecting block 3, so that the short axis 303 on the surface of the limiting plate 302 is separated from the surface of the through hole 107 and the positioning hole 304, thereby moving the long plate 305 on the surface of the connecting block 3 laterally. When the position of the patient requiring surgery deviates, there is no need to adjust the position of the patient's body. The first expansion piece 306 on the surface of the long plate 305 is aligned with the patient's rib on the other side. When the threaded rod 2 308 inside the limiting groove 307 is rotated, the second expansion piece 309 on the outer surface of the threaded rod 2 308 is driven to move, thereby expanding the patient's rib on the other side. At the same time, one end of the second expansion piece 309 is movably embedded in the inner wall of the limiting groove 307 to prevent deflection during movement and affect the operation. Through the rapid adjustment of the position, the risk caused by the long preparation time for surgery is reduced.
