Description

Thoracic cavity opening fixer Technical Field The utility model relates to the technical field of medical equipment, in particular to a thoracic cavity opening fixer. Background The thoracic vertebral tuberculosis is most common in spinal tuberculosis, and the current clinical common operation method has a lateral front access, but the lateral front access needs to cut off ribs or transverse processes, so that the operation is large in wound, long in operation time and large in bleeding amount, the front middle column of a pathological change vertebral body cannot be fully exposed, the operation field is limited, and the focus is not easy to clear thoroughly and is easy to relapse. Therefore, new alternative surgical modes, such as a surgical mode for improving the intercostal thoracic access, are gradually needed in the industry, and the surgical mode does not need to cut off ribs or transverse processes because the intercostal access enters the pleural cavity, so that the surgical mode has the advantages of small surgical wound, short surgical time, clear surgical field exposure and the like. The rib and the skin are strutted by the chest cavity strutted fixer in the two operation modes, at present, the most common chest cavity strutted fixer comprises a dental plate and a pair of strutted arms, at least one strutted arm is slidably arranged on the dental plate, each strutted arm is provided with a strutted plate, the strutted arm which slides relative to the dental plate is provided with a rotary handle, and the rotary handle is used for adjusting the sliding position of the strutted arm on the dental plate. The outward ends of the two expanding arms on the thoracic cavity expanding fixer are easy to deform due to extrusion of the pleural cavity and the ribs, so that the expanding distance between the outward ends of the two expanding arms is reduced, and the operation field is affected. Aiming at such a situation, the prior patent CN 202011405709.1-a chest opener for chest surgery operation discloses that the guard board is supported by the fixing board, so that the guard board is prevented from being stressed to shrink, the chest of a patient can be spread to an accurate position, and the visual field space of doctor operation and the later recovery of the patient are not influenced, so that the whole production is not influenced. Although adjusting device can realize the flexible, but this structure can not slide relatively the sliding arm, and position adjustment is inconvenient, and this structural design itself also has the problem that shelters from the art field in specific region appearance simultaneously. Disclosure of utility model In order to overcome one of the defects in the prior art, the utility model aims to provide the thoracic cavity opening fixer, which can keep the opening degree of one outward end of two opening arms, ensure the operation visual field and is convenient to adjust. In order to solve the problems, the technical scheme adopted by the utility model is as follows: The utility model provides a chest struts fixer, includes dental lamina and a pair of arm that struts, at least one strut arm slidable mounting is on the dental lamina, every strut all be provided with on the arm and strut the board, it is relative be provided with twist grip on the arm is struts to dental lamina gliding, still include auxiliary stay device, auxiliary stay device includes rotatory sleeve and screw thread spin-on the regulating arm on rotatory sleeve both ends, two screw thread revolves to opposite direction between regulating arm and the rotatory sleeve, two the outside one end of regulating arm all is provided with the connecting block, every all articulates on the connecting block has the briquetting, two the briquetting can respectively with two prop the inner wall butt of the outside one end of arm. Further, each pressing block is provided with a hinge shaft in the middle of one side, and the two connecting blocks are respectively and rotatably connected with the hinge shafts on the corresponding pressing blocks. Further, a clamping groove for accommodating the supporting arm is formed in the side face of each supporting block, which is opposite to the hinge shaft. Further, two ends of each propping block are located at two ends of the opening of the clamping groove, and extension parts are outwards arranged and are propped against the inner walls of the corresponding propping arms. Further, the connecting block comprises a connector and a rotating head, at least one connecting unit block is arranged between the connector and the rotating head, one end of the adjusting arm, which is far away from the rotating sleeve, is sleeved on one outward end of the connector, and one end of the rotating head, which is far away from the connector, is rotatably arranged on the hinge shaft. Further, each pressing block is provided with a spreading part on one side, one outward end of the spreading part is
