This invention discloses a series of osteotomy guides for condylar osteotomy and their manufacturing method, relating to the field of medical device technology. The manufacturing method includes the following steps: creating a hard plaster dental model; establishing a virtual three-dimensional craniomaxillary model; acquiring virtual dentition data and replacing the dentition data in the three-dimensional model with virtual data; determining the target position of the mandibular bone segment; planning and virtually designing the osteotomy lines for coracoid and condylar resection, and virtually resecting the affected side's coracoid and condylar processes, and virtually designing the affected side's temporomandibular joint reconstruction to obtain a three-dimensional model of the affected side's ascending ramus; drawing the coracoid osteotomy guide; drawing the condylar osteotomy guide based on the mandibular morphology and osteotomy line position; and three-dimensionally printing the guide. By employing the above method, the guide can be fixed using its own shape, eliminating the need for additional fixation measures, reducing the difficulty of the procedure, shortening the operation time, and improving the accuracy of condylar resection; it also reduces the possibility of design errors caused by multi-data matching and fusion during the digital design process.

The utility model provides an acromioclavicular dislocation resetting and pressurizing thread passing device which comprises a thread passing structure, an adjusting structure and a longitudinal pressurizing thread guiding structure. The wire passing structure assists the lead to be arranged around the coracoid; the wire passing structure comprises two wire passing handles; the adjusting structure adjusts the second end of the wire passing structure to be opposite and separated; and the longitudinal pressurizing thread guide structure is a thread kirschner wire for guiding the thread kirschner wire to drill into the bone. Therefore, the adjusting structure adjusts the opening size of the opening end of the thread passing structure, and convenient and accurate thread winding on the coracoid through the thread passing handle is achieved. Besides, the longitudinal pressurizing thread guide structure can pressurize and reset the clavicle, and the thread kirschner wire is guided by the longitudinal pressurizing thread guide structure when drilling a bone tunnel, so that the positioning is more accurate, the surgical operation is facilitated, the surgical time is saved, the surgical success rate is improved, and the satisfaction degree of a patient is increased.

The invention discloses a series of osteotomy guide plates for condylar osteotomy and a manufacturing method of the series of osteotomy guide plates, and relates to the technical field of medical instruments. The manufacturing method comprises the following steps: manufacturing an anhydrite tooth model; establishing a virtual three-dimensional cranio-jaw model; acquiring virtual dentition data, and replacing the dentition data in the three-dimensional data with the virtual dentition data; determining a target position of the mandibular dental bone section; planning and virtually designing osteotomy lines for coracoid resection and condyle resection, virtually resecting coracoid and condyle on the affected side, and virtually designing temporal-mandibular joint reconstruction on the affected side to obtain a three-dimensional model of the ascending branch on the affected side; drawing a coracoid osteotomy guide plate; drawing a condylar osteotomy guide plate based on the form of the mandible and the position of an osteotomy line; and three-dimensionally printing the guide plate. By the adoption of the method, the guide plate can be fixed through the shape of the guide plate, additional fixing measures are not needed, the operation difficulty is lowered, the operation time is shortened, and the precision of the condylar process resection is improved; and the possibility of design errors caused by multi-data matching fusion in the digital design process is reduced.

The application discloses a coracoid bone cutting, drilling and wire passing system, which comprises a coracoid bone cutting positioner, a box type drilling guider and a scapuloglenoid stable anchor guider, a guide needle is punched to fix the relative position of the coracoid bone cutting positioner and the coracoid bone, then a wire saw, a swing saw or other tools are used to cut the bone along the bone cutting guide plane on the coracoid bone cutting positioner, the accuracy of cutting the coracoid bone is improved, the box type drilling guider serves as an auxiliary tool for drilling the bone cutting block and helps to improve the accuracy of drilling, and the scapuloglenoid stable anchor guider serves as an auxiliary tool for punching an anchor hole and positions the tool for punching the anchor hole, so that the position accuracy of the anchor hole is improved.

The application provides a coracoid wire passing and clavicle drilling positioning auxiliary device, two sides of the clavicle in the length direction are a sternum side and a shoulder joint side respectively, and the coracoid wire passing and clavicle drilling positioning auxiliary device comprises a clavicle positioning piece, the clavicle positioning piece is arranged along the length direction of the clavicle, a positioning hole is formed in the side of the clavicle positioning piece, and the clavicle positioning piece is suitable for clavicle drilling positioning through the positioning hole; a wire passing assembly, the wire passing assembly comprises a wire passing main body connected below the clavicle positioning piece, the wire passing main body is an open structure in an arc shape, and the arc-shaped inner side of the wire passing main body surrounds a coracoid accommodating area. The coracoid wire passing and clavicle drilling positioning auxiliary device can avoid coracoid drilling, maximally reduce secondary stimulation of soft tissues by instruments, reduce the reoperation rate and the opportunity of iatrogenic fracture, shorten the operation time to a certain extent, and reduce the intraoperative infection rate.

The invention belongs to the technical field of molecular markers, particularly relates to an early screening method for low-browning coracoid walnut germplasm resources based on transcription factor expression quantity, and particularly provides a molecular marker related to coracoid walnut germplasm browning, and the molecular marker is a transcription factor AsbHLH68 and / or AsMYB232 gene or an encoding protein thereof, the nucleotide sequence of the AsbHLH68 gene is shown as SEQ ID NO: 5 or a sequence which has more than 90% of homology and has the same function with the nucleotide sequence of the AsbHLH68 gene; the nucleotide sequence of the AsMYB232 gene is as shown in SEQ ID NO: 6; or a sequence which has more than 90% of homology and has the same function. By the adoption of the technical scheme, the breeding cost is reduced, the breeding efficiency is improved, the seedlings can be checked on a large scale in the nursery stage, and most of high-browning-risk inferior single plants can be removed before transplanting and afforestation.
