Description

Technical Field

[0001] The utility model belongs to the technical field of allogeneic bones, in particular to a bone sawing machine used for allogeneic bone production. Background Art

[0002] Allogeneic bone transplantation is an important medical technology used for fracture repair, bone defect repair, and other bone tissue repair surgeries. In this surgery, allogeneic bone from the same species is transplanted into the patient's body to promote bone healing and reconstruction. Allogeneic bone usually undergoes special treatments, such as decellularization and disinfection, to reduce the risk of rejection and increase the success rate of transplantation. In order to meet the needs of allogeneic bone transplantation surgery, an efficient, precise, and safe device is needed to process allogeneic bone. A bone saw is a commonly used tool used to cut allogeneic bone into appropriate sizes to meet the actual needs of the operation.

[0003] After searching, the existing patent (Announcement No.: CN210203133U) discloses a bone sawing machine for allogeneic bone production, including a bone sawing machine body, support plates are arranged on both sides of the lower part of the bone sawing machine body, a workbench is fixed on the upper end of the support plate by welding, a groove is provided in the middle of the rear part of the upper side surface of the workbench, a cutting saw blade is arranged inside the groove, electric telescopic rods are installed on both sides of the front part of the upper side surface of the workbench, the telescopic end of the electric telescopic rod is fixedly connected with a connecting plate by bolts, and positioning blocks are symmetrically arranged on the rear side surface of the connecting plate, an arc-shaped placement groove is arranged on the upper side surface of the positioning block, and a fixed pressure block is connected to the rear part of the upper side surface of the positioning block by a hinge. The utility model can avoid the cutting saw blade from causing harm to the staff, protect the staff, and improve safety. At the same time, it can prevent the allogeneic bone from shaking during cutting, and improve the accuracy of the cutting size.

[0004] However, in the actual use of the above scheme, the temperature of allogeneic bone needs to be paid attention to during the cutting process. Controlling the temperature during the cutting process can ensure the quality and integrity of the bone tissue, while reducing thermal damage and damage to the bone tissue structure. If the temperature during the cutting process is too high, it will cause overheating damage to the bone tissue, making the bone protein inactive, affecting the biological activity and healing ability of the bone. At the same time, high temperature may cause the degeneration of bone tissue and change its structure, thereby affecting the mechanical properties and biological functions of the bone. However, the above device cannot control the cutting temperature.

[0005] To this end, the utility model provides a bone sawing machine for allogeneic bone production. Utility Model Content

[0019] The beneficial effects of the utility model are as follows:

[0020] 1. The utility model discloses a bone sawing machine for allogeneic bone production.
