Problems solved by technology

However, the bending modulus of metal materials is much higher than that of cortical bone, which is prone to stress shielding effect, reduces the speed and quality of new bone formation, leads to osteopenia or osteoporosis, and has the possibility of refracture
After the fracture is repaired, the metal implant needs to be removed by surgery, which brings pain and financial burden to the patient for the second surgery

Embodiment 1

[0028] Please refer to Figure 1 to Figure 4 As shown, the embodiment of the present invention provides an absorbable bone plate, which includes: a bone plate main body 1 and at least one bone plate branch 2 .

[0029] The bone plate main body 1 is made of medical absorbable material; the bone plate branch 2 is made of medical absorbable material. The gears limit the rotation so that the bone plate main body 1 and the bone plate branches 2 form different shapes.

[0030] In this embodiment, specifically, since the bone plate main body 1 and the bone plate branches 2 are made of medical absorbable materials, when the bone plate is implanted in the patient, as the patient slowly recovers, the The bone plate itself will be absorbed by the human body. You only need to take out the limiter 3 in the later stage (if the limiter 3 is a metal piece). At the same time, the limiter 3 can also be made of absorbable materials. If the limiter 3 The part 3 is made of absorbable material an...

Embodiment 2

[0032] refer to figure 1 with figure 2 As shown, on the basis of Embodiment 1, preferably, the bone plate branch 2 is one, and the bone plate branch 2 and the bone plate main body 1 are multi-positioned to limit the rotation through the stopper 3, so that the bone plate main body 1 and the bone plate main body 1 The plate branches 2 form an included angle of the set angle.

[0033] Specifically, in this embodiment, the value range of the setting angle is 0-180°. When the angle between the bone plate branch 2 and the bone plate main body 1 is 180°, the bone plate branch 2 and the bone plate main body 1 is "I"-shaped; when the angle between the bone plate branch 2 and the bone plate main body 1 is 90°, the bone plate branch 2 and the bone plate main body 1 are "L"-shaped; when the bone plate branch 2 and the bone plate When the angle between the main body 1 is other angles, the bone plate branch 2 and the bone plate main body 1 have other corresponding shapes, such as an obli...

Embodiment 3

[0042] refer to image 3 , Figure 4 with Figure 5 As shown, on the basis of Embodiment 1, preferably, there are two bone plate branches 2, and the two bone plate branches 2 are both arranged at one end of the bone plate main body 1, and are connected to the bone plate main body 1 through a limiting member 3. Rotation is limited by multiple gears, so that the bone plate main body 1 and the bone plate branch 2 form a branch shape.

[0043] Specifically, in this embodiment, when the two bone plate branches 2 are perpendicular to the bone plate main body 1 and located on both sides of the bone plate main body 1, the bone plate is in a "T" shape; when the two bone plate branches When the angle between 2 and the bone plate main body 1 is between 90° and 180°, the bone plate is in a "Y" shape; thus, the specific shape of the bone plate can be adjusted according to different usage conditions to improve the bone plate applicability.

[0044] It should be understood that, except f...

Abstract

The invention discloses an absorbable bone fracture plate which comprises: a bone plate body made of a medical absorbable material; and at least one bone plate branch, the bone plate branch is made of a medical absorbable material, the bone plate branch is arranged on the bone plate main body, and the bone plate branch and the bone plate main body are in multi-gear limited rotation through a limiting piece, so that the bone plate main body and the bone plate branch form different shapes. The bone fracture plate can be absorbed by a human body after being implanted into the body of a patient, so that pain of a secondary operation and economic burden brought to the patient are avoided. Meanwhile, stress shielding generated by using a metal bone fracture plate is avoided, and adverse effects on new bones are reduced; by means of the penetrating holes in the absorbable bone fracture plate, flowing of interstitial fluid is facilitated, and the fracture healing speed is increased; in addition, the bone fracture plate can be suitable for more parts, and the applicability of the absorbable bone fracture plate is improved.

Description

technical field [0001] The invention relates to the field of medical auxiliary tools, in particular to an absorbable bone plate. Background technique [0002] Currently, many orthopedic implants are made of metal materials. Metal materials are easy to sterilize, have good biocompatibility, and can provide the necessary fixation strength to support or fix bone tissue. However, the bending modulus of metal materials is much higher than that of cortical bone, which is prone to stress shielding effect, reduces the speed and quality of new bone formation, leads to osteopenia or osteoporosis, and has the possibility of refracture. After the fracture is repaired, the metal implant needs to be surgically removed, which brings pain and financial burden to the patient for a second operation. Contents of the invention [0003] The present invention provides an absorbable bone plate to reduce the stress shielding effect and reduce the adverse effects on new bone, which is suitable f...
