Description

Cutting equipment with freely adjustable medical bone block forming size
Technical Field
The application belongs to the technical field of broken bone cutting equipment, and particularly relates to medical cutting equipment with freely adjustable bone block forming size.
Background
Bone grafting refers to a procedure in which bone tissue is transplanted into a patient where the bone is defective or requires reinforcement or fixation.
After bone grafting, the process of integrating human bones and implanted bone blocks can be seen under a microscope. The bone graft pieces are placed in operation tightly between two or more pieces of bone that are desired to be grown as one piece. Over time, the bone cells within the bone graft die gradually leaving only empty cavities in the bone matrix. At the same time, new bone tissue is continually grown in. Finally, the bone graft is completely phagocytized and absorbed, and replaced with new, living bone tissue. Bone grafting techniques are increasingly used in surgery, just as bone grafting has the effect of promoting bone growth and healing. When the fracture is not healed, especially the fracture is not healed or a false joint is formed due to fracture defect, the fracture can be healed through bone grafting; filling the cavity left after the benign bone tumor is scraped, or bone defect formed after the benign bone tumor is resected; filling the remained cavity after the bone tuberculosis focus is cleared; in the field of orthopaedics, bone grafting is utilized in spinal fusion surgery and joint fusion surgery to improve fusion efficiency.
In the current operation, medical staff on one hand can form required bone blocks by means of biting forceps, but the method is time-consuming and labor-consuming, and the bone blocks with uneven shapes and sizes cannot be guaranteed, so that the bone grafting filling effect is affected. On the other hand, medical staff can also use the broken bone equipment to make the bone piece, but current broken bone equipment mainly relies on the blade that takes shape to cut the skeleton, if need to adjust bone piece shape or size, need change equipment cutting tool to cutting tool specification is limited, can't deal with some special cases, can't cut the bone piece of arbitrary size.

As shown in fig. 7 below, the bone slicing device 7 is composed of an eccentric blade 33, a blade rotating motor 32, a shift screw 30, a screw shift motor 29, a guide rail 35, and a slider 31. The screw rod shifting motor 29 is fixed on the side surface of the chassis (the case guard plate) 1, the rotating shaft of the screw rod shifting motor 29 is in interference fit with the hole shaft of the shifting screw rod 30, the shifting screw rod 30 is in threaded connection with the sliding block 31, the blade rotating motor 32 is fixed in the groove inside the sliding block 31 through screws, the bottom of the sliding block 31 is not contacted with the lower part of the chassis (the case guard plate) 1, and the two sides of the sliding block 31 are provided with guide rails 35. The eccentric blade 33 is fixedly connected (interference fit connection) with the rotating shaft of the blade rotating motor 32 through a hole shaft, wherein the connecting hole of the eccentric blade 33 is deviated from one end of the blade, and when the eccentric blade 33 does not work, one end, which is close to a bone to be cut, of the eccentric blade 33 is a short side, and one end, which is close to the bone block storage box 4, is a long side. When the bone piece is required to be completely cut from the bone, the screw rod shifting motor 29 drives the shifting screw rod 30 to rotate, the shifting screw rod 30 rotates in the sliding block 31, and the sliding block 31 is limited to move in the angle direction due to the fact that the sliding block 31 is clamped between the guide rails 35 on the two sides, so that the sliding block 31 can only move forwards and backwards along the guide rails 35 in the axial direction. According to the bone piece size finally needed to be cut, the eccentric blade 33 is moved to the position below the bone to be cut through the sliding block 31 along the guide rail, and because one end of the eccentric blade 33, which is close to the bone to be cut, is a short side, interference with the bone cannot be formed in the moving process of the eccentric blade 33, after the sliding block 31 drives the eccentric blade 33 to move in place, the blade rotating motor 32 drives the eccentric blade 33 to rotate, the bone is completely cut into the needed bone piece through the long side of the eccentric blade 33, the bone piece can finally fall into the bone piece storage box 4, the bone piece storage box 4 is not fixedly connected with any mechanism, and a user can freely extract the bone piece storage box 4 to take out the bone piece for bone grafting operation.
The cutting device with freely adjustable medical bone block forming size allows a user to input the required bone block size in a touch screen, then the user fixes the allogeneic bone or the synostotic bone on the bone clamping plate, and a control system with a PLC programmable controller cuts the bone downwards by adjusting the distance between blades according to the bone size data input by the user, so as to cut the bone above the clamped part into sheet-shaped bone blocks. The blade is then rotated 90 deg. to continue cutting the bone down, cutting the bone above the clamped portion into strip-shaped bone pieces. The turnover motor drives the bone clamping plate to turn over by 90 degrees, the eccentric blade moves to the lower part of the bone according to user input data, the eccentric blade is rotated to cut the bone into a plurality of granular bone pieces, and the bone pieces finally fall into the bone piece storage box below. According to the application, under the condition that the blade is not replaced, bones with different sizes can be cut into sheet-shaped, strip-shaped or granular bone blocks with different sizes by inputting different parameters into the touch screen, and the requirements of various bone grafting operations can be met.
