Referring to fig. 1 to 5, the present invention provides a fracture fixation structure 100. The fracture fixation structure 100 is mainly used for fixing a fracture site, and particularly, for connecting two fractured bones of the fracture site to heal the fracture site. Of course, the fracture fixation structure 100 can fix a fracture site, and also can achieve the connection of ligament, tendon, and other sites, thereby achieving the repair of a damaged site. The present invention is described by taking the fixed fracture site as an example, and the principle of the fracture fixation structure 100 for fixing the ligament and tendon is substantially the same as the principle of fixing the fracture site, which is not repeated herein.

The utility model discloses a fracture fixed knot constructs 100 fixed fracture position back, can not deviate from the fracture position easily, it is only contrary effectual to end to reliable connection fracture position, make the fracture position can not take place the drunkenness, and then the fracture position healing of being convenient for does benefit to the patient and resumes healthily.

Referring to fig. 1-5, in one embodiment, a fracture fixation structure 100 includes a fixation member 110 and a slip prevention member 120. The fixing member 110 is used to connect the fracture site. The anti-slip member 120 is disposed on the fixing member 110, and after the fixing member 110 is connected to the fracture site, the anti-slip member 120 contacts the fracture site, so as to increase the friction force between the fixing member 110 and the fracture site.

The fixing member 110 may be nailed into the fracture site. It is understood that when a patient is fractured, a crack or fracture will occur in the bone, and the fracture site is the fracture site. At this time, the fixing member 110 is driven into the bones to be connected at the fracture site. The bones to be spliced are connected by the fixing member 110. The fixing member 110 has a certain adhesive force, and after the fixing member 110 is driven into the fracture site, the adhesive force of the fixing member 110 drags the bones of the fracture site, so that the bones of the fracture site are spliced together. In the later healing process, as the fixing part 110 can always splice the bones of the fracture part together, the fracture part can be gradually healed, and the health of the patient can be conveniently recovered.

However, the anchor needs to be driven into the fractured part of the patient during use, and the anchor may be pulled out of the fractured part of the patient by the force such as repulsive force of the bone. That is, the fixation member may have a possibility of moving out to the outside of the fracture site. After the fixing piece is separated from the fracture part, the fixing piece can not be reliably connected with the fracture part, so that the bone separation of the fracture part is caused, the healing of the fracture part is not facilitated, and the conditions of fracture growth dislocation and the like exist in serious cases. Therefore, the anti-slip member 120 is added to the fixing member 110 in the fracture fixation structure 100 of the present invention, and the friction between the fixing member 110 and the fracture site is increased by the anti-slip member 120, so as to restrict the fixing member 110 from moving out of the fracture site.

Specifically, the anti-slip member 120 is disposed on the surface of the fixing member 110. When the fixing member 110 is driven into the fractured portion of the patient, the anti-slip member 120 is also positioned in the fractured portion and is brought into contact with the bone of the fractured portion. The anti-slip member 120 can increase the contact area of the fixing member 110 with the fracture site, and increase the friction force of the fixing member 110 with the fracture site. When the fixing member 110 tends to move toward the outside of the fracture site, the contact of the anti-slip members 120 with the fracture site provides a reaction force, so that the fixing member 110 is reliably located in the fracture site. Thus, the fixing member 110 can reliably connect the fracture part to splice the bones of the fracture part together, so that the fracture part is gradually healed in the later process, and the patient can conveniently recover the health. It should be noted that the inside herein refers to the inside of the fracture site, i.e., the direction in which the fixing member 110 is driven into the fracture site; the outer side refers to the outer side of the fracture site, i.e., the direction opposite to the direction in which the fixing member 110 is driven into the fracture site.

The utility model discloses a fracture fixed knot constructs 100 passes through mounting 110 and connects the fracture position after, antiskid 120 and fracture position contact, and antiskid 120 can increase the frictional force at mounting 110 and fracture position. The problem that the existing U-shaped nail is easy to fall out of bone fragments is effectively solved, the fixing piece 110 is limited to fall out of a fracture part, the non-return effect is good, and the fixing piece 110 is firmly positioned in the fracture part. Thus, the fracture fixation structure 100 can reliably connect the fracture part, so that the fracture part does not move, the fracture part can be conveniently healed, and the recovery of the patient is facilitated.

In one embodiment, the fixing member 110 includes a connecting section 111 and two fixing sections 112, the two fixing sections 112 are oppositely disposed on the connecting section 111, and the two fixing sections 112 are nailed into the fracture site. The two ends of the connecting section 111 are respectively connected with the fixing sections 112. The fixing segments 112 are located on the side of the connecting segment 111 and are arranged to protrude from the connecting segment 111, and the extending directions of the two fixing segments 112 are the same. Specifically, the two fixing sections 112 are respectively nailed into two bones to be spliced at the fracture part, and the connecting section 111 connects the two fixing sections 112, so that the two bones can be spliced together by the connecting force of the connecting piece on the two fixing sections 112 without being separated from each other, thereby realizing the reliable fixation of the fracture part.

Alternatively, the lengths of the two fixed segments 112 may be the same or different. Illustratively, the two fixed segments 112 are the same length. Optionally, the fixing section 112 has a tip 1121, the tip 1121 is located at the end of the fixing section 112 away from the connecting section 111, and the tip 1121 can facilitate the nailing of the fixing section 112 into the fracture site for convenient use. It is understood that the sectional shape of the connection section 111 is not limited in principle as long as the fracture site can be fixed. Alternatively, the cross-sectional shape of the connecting section 111 is circular, elliptical, polygonal, or other shape, etc. Alternatively, the cross-sectional shape of the fixed segment 112 is circular, elliptical, polygonal, or other shape, etc. Optionally, the cross-sectional shapes of the fixing segment 112 and the connecting segment 111 are the same or different. Illustratively, as shown in fig. 1, the cross-sectional shapes of the fixing section 112 and the connecting section 111 are both circular; as shown in fig. 1 to 5, the cross-sectional shapes of the fixing section 112 and the connecting section 111 are both polygonal.

In one embodiment, the cross-sectional area of the connection portion 111 connected to the fixed section 112 is larger than the cross-sectional area of the end of the fixed section 112 away from the connection portion 111. That is, the sectional area of the fixing section 112 is gradually reduced from the connection with the connection section 111 to a position away from the connection section 111. This may facilitate driving of the fixation section 112 into the fracture site.

In one embodiment, the number of fixed segments 112 is at least three. That is, the number of the fixed segments 112 may also be increased. When more bones need to be connected and fixed, the plurality of fixing sections 112 are connected through one connecting section 111, so that the connection and fixation of a plurality of bones at the fracture part are realized. Optionally, the connecting segment 111 has at least one fixed segment 112 on each side, with a space between adjacent fixed segments 112. Of course, the number of the connecting sections 111 is also at least two, and the plurality of fixing sections 112 are connected by at least two connecting sections 111.

Referring to fig. 1, in one embodiment, the anti-slip member 120 includes an anti-slip groove 121, and the anti-slip groove 121 is disposed on at least one surface of the fixed segment 112 along the extending direction of the fixed segment 112. That is, the anti-slip member 120 may be an anti-slip groove 121. The anti-slip groove 121 is recessed in the surface of the fixing section 112. After the anti-slip groove 121 is formed on the surface of the fixing section 112, the anti-slip groove 121 can increase the contact area between the fixing section 112 and the fracture part, so as to increase the friction force between the fixing section 112 and the fracture part and limit the movement of the fixing section 112 out of the fracture part.

Alternatively, the anti-slip groove 121 is provided on one surface of the fixing segment 112. Of course, the anti-slip groove 121 may be disposed on two or more surfaces of the fixing section 112. Alternatively, the surfaces of the two fixing segments 112 having the anti-slip grooves 121 may be the same or different. Illustratively, the anti-slip groove 121 is located on the outer side surface of the fixed segment 112, as shown in FIG. 1. Of course, the anti-slip groove 121 may be located on the inner side surface of the fixing segment 112. Alternatively, the number of the anti-slip grooves 121 is plural, and the plural anti-slip grooves 121 are arranged at intervals along the extending direction of the fixing segment 112.

Referring to fig. 2, 3 and 5, in one embodiment, the anti-slip member 120 includes a stud 122, and the stud 122 is disposed on at least one surface of the fixing segment 112 along the extending direction of the fixing segment 112. That is, the cleats 120 may be cleats 122. The anti-slip protrusions 122 are disposed to protrude from the surface of the fixing section 112. After the anti-slip protrusions 122 are disposed on the surface of the fixing section 112, the anti-slip protrusions 122 may increase the contact area between the fixing section 112 and the fracture site, so as to increase the friction force between the fixing section 112 and the fracture site and limit the movement of the fixing section 112 out of the fracture site.

Optionally, a non-slip protrusion 122 is provided on one surface of the fixed segment 112. Of course, the anti-slip protrusions 122 may be disposed on two or more surfaces of the fixing section 112. Alternatively, the surfaces of the two segments 112 having the cleats 122 may be the same or different. Illustratively, the cleats 122 are located on the outer side surface of the securing segment 112, as shown in FIG. 2. Of course, the stud 122 may also be located on the inside surface of the anchor segment 112. Optionally, anti-slip protrusions 122 are provided on at least two surfaces of the fixed segment 112. Illustratively, the cleats 122 may also be located on the inside and outside surfaces of the securing segment 112, as shown in FIG. 5. Alternatively, the number of the antiskid projections 122 is plural, and the plural antiskid projections 122 are arranged at intervals along the extending direction of the fixing section 112.

Referring to fig. 2 and 3, in one embodiment, the stud 122 has an inclined surface 1221, one end of the inclined surface 1221 is connected to the fixing section 112, and the other end of the inclined surface 1221 protrudes from the fixing section 112, and the inclined surface 1221 is used to guide the fixing section 112 to move into the fracture site. That is, the inclined surface 1221 is inclined away from the fixed segment 112. The inclined surface 1221 makes the fixing section 112 taper, increasing the cross-sectional area of the fixing section 112 away from the tip 1121. Thus, the inclined surface 1221 may guide the fixation section 112 into the bone of the fracture site during the process of driving the fixation section 112 into the fracture site of the patient. The inclined surface 1221 may increase the contact area of the fixing section 112 with the fracture site after the fixing section 112 is driven into the fracture site. After the fixing section 112 is driven into the fracture part, the inclined surface 1221 can limit the end portion protruding out of the fixing section 112 and can limit the fixing section 112 from moving out of the fracture part due to the inclined direction of the inclined surface 1221, thereby ensuring that the fixing section 112 can reliably fix the fracture part.

The section of the inclined surface 1221 connected to the fixed section 112 is a fixed end, and the end portion extending away from the fixed section 112 is a free end. That is, the free end serves as a stop to prevent the fixation section 112 from moving out of the fracture site and to restrict the reverse movement of the fixation section 112. Illustratively, as shown in fig. 2, the anti-slip member 120 is located on the outer side surface of the fixed section 112, one end of the inclined surface 1221 close to the end of the fixed section 112, i.e., the fixed end, is connected to the fixed section 112, and one end of the inclined surface 1221 away from the end of the fixed section 112, i.e., the free end, is inclined toward the outer side of the fixed section 112.

In one embodiment, the stud 122 further has a stop surface 1222, the stop surface 1222 is located at the end of the inclined surface 1221 protruding from the fixation section 112, and the stop surface 1222 can abut the fracture site. That is, the stop surface 1222 is connected to the free end of the inclined surface 1221. The reverse movement of the fastening portion 112 is stopped by the stop surface 1222. When the fixation section 112 has a tendency to move toward the outside of the fracture site, the contact of the stop surface 1222 with the fracture site provides a reaction force that secures the fixation section 112 in the fracture site. Alternatively, the stop surface 1222 may be planar. Of course, the stop surface 1222 may also be an inclined surface, which is inclined in the same or different direction as the inclined surface 1221.

Of course, in other embodiments of the present invention, the anti-slip protrusions 122 may also be anti-slip ribs, anti-slip particles, or other components capable of increasing friction.

In one embodiment, the anti-slip device 120 includes a stud 122 and a groove 121, the stud 122 and the groove 121 are respectively disposed on the fixing section 112, and the stud 122 and the groove 121 are disposed in a different plane or coplanar. That is, the stud 122 and the cleat groove 121 may be used in combination, and the fixing segment 112 is fixed by the stud 122 and the cleat groove 121 together, so that the fixing segment 112 is reliably located in the fracture site. The stud 122 and the groove 121 may be located on the same surface or different surfaces. It should be noted that the specific arrangement of the anti-slip protrusions 122 and the anti-slip grooves 121 has been mentioned above, and is not described herein.

Referring to fig. 3, in an embodiment, the anti-slip device 120 further includes a fixing protrusion 123, the fixing protrusion 123 is disposed on the connecting section 111, the fixing protrusion 123 extends in the same direction as the fixing section 112, and the fixing protrusion 123 can be driven into the fracture site. The fixing protrusion 123 has a fixing function, and further fixing of the fixing section 112 in the fracture site is achieved. The fixing protrusion 123 is disposed on the surface of the connecting section 111 and protrudes from the surface of the connecting section 111, and the fixing protrusion 123 is aligned with the extending direction of the fixing section 112. Thus, after the fixing section 112 is driven into the fracture site of the patient, the fixing protrusion 123 is driven into the fracture site of the patient, thereby further fixing the fracture site. Meanwhile, the fixing protrusion 123 increases a contact area of the fixing member 110 with the fracture site, and further increases a frictional force between the fixing member 110 and the fracture site, so that the fixing member 110 is restricted in the fracture site, and the fixing member 110 is not easily separated from the fracture site.

Alternatively, the fixation protrusion 123 is a tapered protrusion through which the fracture site is driven. Of course, in other embodiments of the present invention, the fixing protrusion 123 may also be a fixing column or other component that can be driven into the fracture site.

Referring to fig. 4, in one embodiment, the anti-slip device 120 further includes a fixing hook 124, the fixing hook 124 is disposed at an end of the fixing segment 112, and the fixing hook 124 protrudes toward between the two fixing segments 112. After the fixing section 112 is driven into the fracture site of the patient, the fixing hook 124 is hooked on the fracture site. Moreover, since the fixing hook 124 hooks the fracture part, the fixing hook 124 can limit the fixing section 112 from moving out of the fracture part, thereby ensuring the fixing of the fixing section 112 to be reliable.

In one embodiment, the fixing member 110 and the anti-slip member 120 are of a unitary structure. That is, the fixing member 110 and the anti-slip member 120 are integrally formed. Thus, the number of parts can be reduced, and the medical staff can use the medical staff without assembling. In addition, the strength of the joint of the fixing member 110 and the anti-slip member 120 which are integrally formed can be ensured, so that the fixing member 110 is prevented from being separated from the anti-slip member 120 in the fixing process, and the fixing effect is ensured.

Referring to fig. 5, in an embodiment, the connection section 111 further has a limiting hole 1111 disposed therethrough, and the limiting hole 1111 is used for fastening a fracture site. The limiting hole 1111 also has a limiting function, so that the fixing member 110 can be prevented from moving out of the fracture site. After the fixing section 112 is nailed into the fracture site of the patient, the connecting section 111 is also attached to the fracture site, and at this time, the fracture site can be accommodated in the limiting hole 1111, so as to increase the contact area between the fixing member 110 and the fracture site, thereby limiting the fixing member 110 from moving out of the fracture site and ensuring that the fixing section 112 can reliably fix the fracture site. Alternatively, the shape of the fixing hole is circular, polygonal, or other shapes, etc.

In one embodiment, at least two surfaces of the fixing segment 112 have the anti-slip members 120, and the anti-slip members 120 of at least two surfaces are at least partially offset along the extending direction of the fixing member 110. That is, when the anti-slip members 120 are located on at least two surfaces of the fixed segment 112, the projections of the anti-slip members 120 on the at least two surfaces in the extending direction of the fixed segment 112 are not coincident. As shown in fig. 5, the fixing section 112 has a first surface and a second surface opposite to the first surface, the first surface and the second surface both have the anti-skid device 120, and the anti-skid device 120 on the first surface and the anti-skid device 120 on the second surface are disposed in a staggered manner in the extending direction of the fixing section 112. Of course, in other embodiments of the present invention, the anti-slip members 120 may be disposed on three surfaces or four surfaces of the fixed section 112, and the projections of the anti-slip members 120 on several surfaces in the extending direction of the fixed section 112 are not overlapped. Of course, the anti-slip members 120 of the respective surfaces may also partially or completely overlap in the extending direction of the fixing segment 112.

In one embodiment, the surface of the fixed segment 112 has at least partially a skid-proof member 120 along the extending direction of the fixed segment 112. That is, the number of the anti-skid devices 120 is plural, and the plural anti-skid devices 120 may be distributed on one surface or plural surfaces of the fixing section 112 along the extending direction of the fixing section 112, or may be disposed on only a part of the surface of the fixing section 112. Illustratively, as shown in fig. 2 and 3, cleats 120 are disposed across one surface of fixed segment 112; as shown in fig. 5, the anti-slip members 120 are provided on a part of the surface of the fixing segment 112.
