However, the use of auxiliary devices can further improve the efficiency and effect of thoracotomy. In summary, the inventors have found that the existing thoracotomy assisting device mainly has the following defects: since the area where the current thoracotomy assisting device contacts the ribs is very likely to fall off automatically due to the body's toughness rebound when there is no manual support from medical staff during the operation, it will reflect the defect that the assisting device cannot remain stable without human intervention. At the same time, the thoracotomy assisting device has a certain volume, which will block part of the thoracotomy area, thereby hindering the stable progress of the operation.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is based on the surgical groove of the spliced ​​body, which can avoid the obstruction of the surgical area caused by the intervention of the auxiliary device, and then use the two sets of internal expansion contactors to evenly and stably pry the ribs apart after the thoracotomy (for use in some large and complex thoracotomy surgeries that require rib cutting, such as lung transplantation surgery, by auxiliary expansion of the ribs to obtain a better field of view and surgical operation space), while the contact body of the force-bearing block can be combined with the anti-rust plate and the flexible sleeve to contact and align with each rib, and finally the ribs will be fixed one by one by the limiting ring and the circular groove, avoiding automatic sliding caused by no one watching.

[0019] 2. The present invention is further improved by the flexible sleeve. The solid wall of the rubber block can be in direct contact with the ribs. The characteristics of the medical rubber can increase the friction between the instrument and the body, thereby improving the fixation and preventing damage to the muscles around the ribs caused by fixation, thereby improving the protection effect. Finally, the block and the frame at the bottom connecting end can facilitate the removal of the rubber block from the anti-rust plate area, thereby achieving the effect of facilitating the cleaning and disinfection of the rear area.

[0020] 3. After the fixer of the present invention is further improved, the plate body will be combined with the central protrusion to complete the connection with the force-bearing block, and then the positioning block on the edge can determine the position of the pull rod, so that the pull rod can enter the inside of the force-bearing block when it is pushed inward through the disassembly block, and then the magnetic block of the disassembly block can be adsorbed and fixed on the outer surface of the parallel rail, thereby completing the effect of auxiliary fixation of thoracotomy, and further preventing the device from falling off due to the influence of the flexible rebound of the muscle trunk. On the contrary, the magnetic block of the disassembly block is separated from the external foundation of the parallel rail to pull the pull rod out of the force-bearing block area, so that the force-bearing block can drive the contact body to slide parallel in the parallel rail area again, thereby achieving the adjustment of the fixing range according to the actual position of the ribs, thereby improving the stability and matching of assisted thoracotomy.

[0041] Specific functions and operation procedures of this embodiment: In the present invention, First: the splicing body 2 of the thoracotomy auxiliary device for clinical thoracic surgery can be combined with the positioning block 1 to determine the position of the surgical slot 3, so that the splicing body 2 can be installed on the bed through the positioning block 1, and then the surgeon can determine the positioning position by himself, so that the positioning block 1 will be embedded in both sides of the bed, so that the splicing body 2 can be positioned parallel to the patient's chest, and then the splicing body 2 can avoid the obstruction of the surgical position through the cooperation of the surgical slot 3. For some complex thoracotomy operations (such as lung transplantation operations), the chest ribs need to be surgically disconnected, and then the two sets of internal expansion contactors 5 can be used to slide in parallel in the parallel rail 4 area to stably expand the ribs on both sides evenly, thereby achieving the effect of thoracotomy auxiliary surgery. At the same time, the expansion contactor 5 can be fixed in position after moving in parallel with the parallel rail 4, so that the automatic detachment of the device caused by the body's toughness rebound due to unattended operation can be avoided; Second: the force block 52 of the opening contactor 5 can form a stable "L" shape with the contact body 53, so that the control block 54 on the force block 52 can allow the surgeon to manually control it. Therefore, the force block 52 can slide in parallel in the parallel rail 4 area in combination with the edge fixer 51, so that the contact body 53 of the force block 52 can stably open the ribs, and finally be positioned at any area of ​​the parallel rail 4 through the fixer 51, so that the limitation of the fixed area can be avoided, the auxiliary device can be adapted to various personnel for use, and the difficult stable fixation caused by different degrees of thoracotomy can be avoided; Third: the solid plate 532 of the contact body 53 can be embedded in the force-bearing block 52 in parallel through the plug block 531, and then fixed by two locking bolts 533, so that the anti-rust plate 534 and the flexible sleeve 535 can be easily removed from the force-bearing block 52 area at a later time through the interlaced locking effect, so as to achieve the characteristic of being able to be disassembled and disinfected separately, and then the surface of the anti-rust plate 534 at the lower end of the solid plate 532 will be covered by the flexible sleeve 535, so that the flexible sleeve 535 will replace the anti-rust plate 534 to be directly contacted and fixed with the ribs, and then the medical rubber material of the flexible sleeve 535 can be used in the process of contacting with the ribs and muscles without causing secondary damage such as friction to them, so as to ensure that the disconnection surface can be kept consistent, and prevent secondary damage from increasing the risk of patients; Fourth: The flexible sleeve 535 can achieve a protective effect according to its own medical rubber block 352, and then the rubber block 352 can be vertically embedded in the surface of the anti-rust plate 354 through the overlap groove 351 to cover it, completing the connection with the anti-rust plate 534, and then through the multiple groups of positioning plates 353 and the limiting rings 354 and the circular grooves 355 on the surface, it can be aligned, contacted and fixed with each rib one by one, achieving a complete protection and limitation effect, and at the same time, the increased friction of the rubber can further prevent automatic shedding caused by the influence of body fluids; Fifth: the solid wall 3521 of the rubber block 352 can complete the connection with the positioning plate 353, and then the card block 3523 can carry the frame 3524 to connect to the lower end of the rubber block 352 through the connecting end 3522 at the lower end, so that the frame 3524 can be manually pulled downward through the empty groove 3525, so as to force the rubber block 352 to be pulled out from the surface of the anti-rust plate 354, thereby achieving the effect of easy disassembly and assembly, so that it can be disinfected and maintained separately or replaced with a new one, avoiding the cross-infection caused by the failure to properly handle the detailed areas due to the overall unified disinfection and subsequent reuse.

Its structure includes: the fixer 51 is provided with a central protrusion 511, a plate body 512, a positioning block 513, a pull rod 514, and a disassembly block 515. The central protrusion 511 is welded to the center of the plate body 512 and is perpendicular to each other. The surface of the plate body 512 is equipped with two positioning blocks 513 and are symmetrical to each other. There are two pull rods 514 in total, and they penetrate the center of the positioning block 513 one by one from both sides of the plate body 512 and the central protrusion 511. The disassembly block 515 is fixedly connected to one end of the pull rod 514.

[0043] Among them, the length of the central protrusion 511 is consistent with the length of the plate body 512, the two positioning blocks 513 on the plate body 512 are both square in shape and have a through groove in the center with the same shape as the pull rod 514, and the area of ​​the disassembly block 515 is larger than the area of ​​one end of the pull rod 514.

[0044] Among them, the disassembly and assembly block 515 is provided with an anti-deviation block 151, a restraining block 152, a handheld body 153, a magnetic block 154, and an assembly groove 155. The anti-deviation block 151 and the restraining block 152 are on the same parallel line and are both installed on the surface of the handheld body 153 and are matched with each other at a distance. The handheld body 153 is precisely overlapped and connected with the lower end of the magnetic block 154 through the restraining block 152 and the anti-deviation block 151. The assembly groove 155 runs through the center of the magnetic block 154 and the center is the same as that of the restraining block 152.

[0045] There are two anti-deflection blocks 151 on the surface edge of the restraining block 152 . The handheld body 153 is a square solid shape. The shape and position of the magnetic block 154 are consistent with the shape and position of the handheld body 153 and are connected through the anti-deflection block 151 .

[0046] Specific functions and operation procedures of this embodiment: In the present invention, First, the plate 512 of the fixer 51 can be fixedly connected with the two sides of the force block 52 through the central protrusion 511, and then the positioning block 513 of the plate 512 allows the pull rod 514 to penetrate, so that after the position of the force block 52 is adjusted by the control block 54, the pull rod 514 will be pushed into the force block 52, and then the disassembly block 515 at the other end of the pull rod 514 can be stably adsorbed on the outside of the parallel rail 4 in parallel according to its own magnetic attraction effect, and the forced adsorption can make the open contactor 5 have a fixing effect at any place, and then the magnetic attraction characteristic can achieve an effect of easy control; Second: The handheld body 153 of the disassembly block 515 can be connected with the magnetic block 154 in parallel through the surface restraint block 152 and the anti-bias block 151 to prevent the center point from being inconsistent after assembly. Then, the assembly groove 155 at the center of the magnetic block 154 allows the pull rod 514 to be embedded, so that after the pull rod 514 enters the center of the handheld body 153 through the disassembly groove 155, the restraint block 152 at the center of the handheld body 153 can be embedded in the center of the pull rod 514, thereby improving the center of the pull rod 514. The restraint limitation prevents tilting caused by center point error. Finally, the magnetic block 154 can be adsorbed on the outside of the parallel rail 4 according to its own magnetic characteristics to achieve a positioning effect. On the contrary, after the operation is completed, the magnetic block 154 is first forcibly pulled out of the parallel rail 4 area through the handheld body 153, so that the pull rod 514 will be separated from the inside of the force-bearing block 52, so that after the restraint force on both sides of the force-bearing block 52 disappears, it can slide left and right in the parallel rail 4 area again, achieving an effect of easy control and improving the strength of surgical assistance.
