Embodiment 1

[0041] Such as Figure 1-4 As shown, the spinal bone surface anastomosis positioning drill guide includes an anastomosis module 1, and a connecting plate 2 is also arranged on the anastomosis module 1, and a fixing hole is arranged on the connecting plate 2, and a module fixing screw 3 is arranged in the fixing hole With the integral fixing screw 4, the anastomosis module 1 includes a left anastomosis module 11 and a right anastomosis module 12, and a guide hole 5 is respectively arranged on the left anastomosis module 11 and the right anastomosis module 12, and a guide hole 5 is arranged on the inner wall of the guide hole 5. Provided with thin-walled stainless steel tubes. Setting a thin-walled stainless steel tube inside the guide hole can well isolate the guide hole from the middle through hole. When drilling with the guide hole, it avoids the contact between the guide hole and the drill bit of the drill hole, thereby preventing the guide hole from being blocked by the dri...

Embodiment 2

[0045]The preparation method of the positioning drill guide for spinal bone surface anastomosis comprises the following steps:

[0046] A. Use the 3D design software to reverse the 3D model of the patient's bone provided by the medical institution to obtain the 3D models of the left and right anastomotic modules; Figure 5 As shown, the specific design steps are as follows:

[0047] A1. Import the 3D model of the patient's bone into the 3D design software, and create a cuboid model slightly larger than the bone model;

[0048] A2. Adjust the relative position of the skeleton model and the cuboid model, so that the skeleton model is in the center of the cuboid model, and make the skeleton model completely wrapped by the cuboid model;

[0049] A3. Through Boolean subtraction, remove the area overlapping with the skeleton model in the long-haired body model, and then obtain a cuboid shell that completely matches the skeleton model;

[0050] A4. Divide it into left and right par...

Abstract

The invention discloses a spine bone surface anastomosis positioning drilling guider which comprises an anastomosis module. The anastomosis module comprises a bone surface fitting face, two guide holes are formed in the anastomosis module and in two sides of a central line of a fitting body respectively, and a thin-wall stainless steel pipe is arranged on the inner wall inside each guide hole. By the spine bone surface anastomosis positioning drilling guider and the manufacturing method, the problems of high operating risk, large time consumption, high cost and high patient infection probability in the prior art are solved, risk and time consumption of operation are lowered well, and patient infection probability and operating cost are lowered greatly.

Description

technical field [0001] The invention relates to a guide and a preparation method thereof, in particular to a bone-surface anastomosis guide used in surgical operations and a preparation method thereof. Background technique [0002] The implantation of surgical internal fixation requires drilling a prefabricated screw track on the bone of the patient's surgical site, and then implanting screws along the screw track. There are two main methods of prefabricating the nail path: one is that the doctor directly prefabricates the hole with a medical gram drill based on the image photos and personal experience; During the process of filming for many times, adjustments were made, and then filming and adjustments were made to finally determine the entry point and entry angle of the nail path for prefabrication of holes. The first method relies entirely on experience, and it is very risky for the difficult and harsh implantation surgery; the second method requires cumbersome operatio...
