Problems solved by technology

Traditionally, obtaining patient data through CT, MRI and other imaging equipment is the basis for doctors to pre-plan surgery, but the obtained medical images are two-dimensional, and these data are difficult for doctors to obtain during clinical operations. Accurately grasp the accuracy of the operation, which leads to many failed operations
Especially in the case of orthopedic surgery that requires screw placement and accurate connection of bone blocks, it is difficult to perform precise surgery with two-dimensional data

Embodiment 1

[0016] Patient 1: female, 49 years old, in late June 2019, due to accidental “swelling and pain in the right foot, limited movement” due to accidental “sprain” while walking on the mountain in late June 2019. At that time, the X-ray showed that the 2nd to 4th metatarsal bones of the right foot were fractured, and a plaster fixation was given and local symptoms were given. Treatment and other conservative treatment, after 7 weeks of treatment, he felt that the swelling and pain were limited and his activities were not relieved, so he went to the doctor again for examination and was diagnosed with "Lisfranc fracture and dislocation of right foot", and was admitted to the hospital for further treatment. After being admitted to the hospital, complete examinations, such as right foot MRI / CT / foot weight-bearing anteroposterior and lateral X-rays, were performed to confirm the diagnosis, and about 8 weeks after the injury, "right foot Lisfranc fracture dislocation open reduction, plate...

Embodiment 2

[0035] Patient 2: Male, 49 years old, underwent open reduction of the lateral malleolus plate and internal fixation of the medial malleolus cannulated screw due to "left double malleolus fracture" in the inpatient department one year ago. The hollow nail guide pin broke during the operation, resulting in a broken guide pin remaining in the bone. Considering that the broken guide pin is in the tibial medullary cavity, it is difficult to remove during the operation, and it is easy to cause bone destruction and affect fracture healing. After communicating with the patient, it was agreed not to take out the broken guide pin for the time being, and to take out the residual guide pin when the fracture healed and the internal fixation was removed. After the operation, the patient recovered well and was followed up regularly. During the period, no special circumstances were reported. A review film one year after the operation indicated a fracture Healed, then admitted to the hospital f...

Abstract

The invention relates to a manufacturing method of a medical tool, in particular to a preparation method of a 3D printing body surface guide plate. The method comprises the steps of collecting data, and reconstructing a 3D model with a positioning gasket with the help of three-dimensional design software in data processing equipment; importing the obtained 3D model into three-dimensional modelingsoftware through an STL format file, and establishing an original body surface base guide plate on the body surface around the model metal gasket; re-importing the original body surface guide plate into the three-dimensional design software through an STL format file, and designing at least two positioning holes in the positions of central holes of the two metal gaskets by the original body surface base guide plate; and determining the position of the guide hole sleeve on three-dimensional modeling to form a 3D body surface guide plate model, guiding the 3D body surface guide plate model intoa 3D printer, and forming a 3D printing body surface guide plate through printing. By utilizing the guide plate, the positioning accuracy can be actively improved, and the positioning accuracy can beeffectively improved by using more positioning points, so that the accuracy and the success rate of an operation are improved.

Description

technical field [0001] The invention relates to a method for making a medical tool, in particular to a method for preparing a 3D printed body surface guide plate for inserting or removing screws. Background technique [0002] For high-risk and difficult surgeries, preoperative planning is very important. Traditionally, obtaining patient data through CT, MRI and other imaging equipment is the basis for doctors to pre-plan surgery, but the obtained medical images are two-dimensional, and these data are difficult for doctors to obtain during clinical operations. Accurately grasp the accuracy of the operation, which leads to many failed operations. Especially in the case of orthopedic surgery that requires screw placement and precise connection of bone blocks, it is difficult to perform precise surgery with two-dimensional data. Contents of the invention [0003] In view of the above-mentioned technical problems, the present invention in order to greatly improve the surgical...
