Embodiment 1

[0036] Such as figure 1 with figure 2 As shown, the embodiment of the present invention provides a guide plate, which includes a base 11 and a guide column 12 . The abutment 11 is used to be attached to the surface of the greater trochanter of the femur, specifically to the cortical bone below the greater trochanter of the femur, so as to fix the relative position between the guide plate and the femur. The thickness of the abutment 11 can be set between 2 to 5 millimeters, in this embodiment, it is 3 millimeters, so that the abutment 11 can have a certain strength, and at the same time has the advantages of lightness.

[0037] The guide column 12 is disposed on the base 11 , and a guide hole 120 is disposed in the guide column 12 . Such as image 3 As shown, the guide post 12 is used to guide the guide pin 14, so that the guide pin 14 can drill into the femoral head 15 and enter the center of the necrotic lesion. Then you can use the guide wire to ream the marrow to estab...

Embodiment 2

[0042] An embodiment of the present invention provides a kind of manufacturing equipment of the above-mentioned guide plate, such as Figure 4 As shown, the manufacturing equipment includes a medical image control system (Materialise's interactive medical image control system, Mimics for short) 21 and a 3D printer 22 .

[0043]Among them, the Mimics system 21 is used to create the shape model of the guide plate. Mimics system 21 is a set of highly integrated and easy-to-use 3D image generation and editing software. data, and create a 3D model for editing, and then output general-purpose computer-aided design (Computer Aided Design, referred to as CAD), finite element analysis (Finite Element Analysis, referred to as FEA), rapid prototyping (Rapid Prototyping, referred to as RP) and other formats, so you can Perform large-scale data conversion processing on the computer.

[0044] The FEA function of the Mimics system can quickly process the scanned input data and output the c...

Abstract

The invention provides a guide plate and manufacturing equipment thereof and relates to the technical field of medical instruments. The problem that an existing hip-preserving operation is not good in treatment effect is solved. The guide plate comprises a base table and a guide column. The base table is used for being attached to the surface of the greater trochanter of the thigh bone. The guide column is arranged on the base and used for guiding-in of a guide needle, and then the guide needle drills into the thigh bone.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a guide plate and manufacturing equipment thereof. Background technique [0002] Femoral head necrosis is a common disease. The etiology of femoral head necrosis is varied, but its common pathological mechanism is bone tissue ischemia. Due to various internal and external pathogenic factors, the nutritional blood flow of bone tissue is reduced, the intraosseous vascular network is compressed, or the outflow vein is blocked, resulting in local blood supply disturbance, and severe cases can cause bone tissue ischemic necrosis. [0003] Debridement of femoral head necrosis lesions and compression of bone grafting and fibula support is the basic surgical procedure for hip-preserving treatment of femoral head necrosis. The purpose of the operation is to prevent the collapse of the femoral head and promote the repair of necrosis. In order to obtain a good surgical effect, ...
