Description

Technical Field

[0001] The present disclosure relates to the technical field of medical devices, and particularly to a method for manufacturing a fixing member, a fixing member, and a traction wearing assembly. Background Art

[0002] In orthopedic clinics, for orthopedic and internal fixation surgeries related to the skull and spine such as the treatment of adolescent idiopathic scoliosis and cervical fractures, preoperative traction is usually required to stretch the vertebral body to facilitate the operation. Existing medical devices mainly use metal ring-shaped fixing members. During long-term wearing, when the patient lies down, the fixing nails at the back of the skull support the skull in a suspended state, which not only is not conducive to the patient's rest but also poses a great safety risk.

[0003] The prior art such as CN202554088U discloses a head and neck traction frame that uses a C-shaped fixing member. Although this fixing member can avoid the defects of the above-mentioned metal ring-shaped fixing member and is also disclosed to be made of carbon fiber material and the fixing member is a solid structure, if the strength of the fixing member is poor, the opening of the fixing member will deform greatly when the fixing nail is driven into the skull, and the nail path will also change with the deformation of the fixing member, making the nail path larger, which has a greater impact on subsequent effective fixation and increases the patient's wound surface. During long-term wearing (3 months to 18 months), it may cause complications such as infection, resulting in the failure of the operation; if the strength of the fixing member is good, more carbon fiber materials are used for the fixing member, then the cost of the fixing member is higher, undoubtedly bringing a greater economic burden to the patient. Summary of the Invention

[0004] The purpose of the present disclosure is to overcome the deficiencies in the prior art and provide a method for manufacturing a fixing member, a fixing member, and a traction wearing assembly with better structural strength and lower cost.

[0005] The purpose of the present disclosure is achieved through the following technical solutions:

[0006] A method for manufacturing a fixing member, comprising:

[0007] Forming a first fixing member unit and a second fixing member unit, a first hollowed-out area is formed on the connection surface of the first fixing member unit, and a first reinforcing rib is formed in the first hollowed-out area. A second hollowed-out area is formed on the connection surface of the second fixing member unit, and a second reinforcing rib is formed in the second hollowed-out area;

[0008] Aligning and abutting the first fixing member unit with the second fixing member unit, so that the first hollowed-out area is communicated with the second hollowed-out area, and the first reinforcing rib abuts against the second reinforcing rib to form a structure to be wound;

[0010] Perform a thermosetting treatment on the winding structure to form the semi-finished fixing part;

[0012] In one embodiment, before the step of aligning and abutting the first fixing part unit with the second fixing part unit, the manufacturing method further includes:

[0016] In one embodiment, the winding part is carbon cloth.

[0017] In one embodiment, before the step of aligning and abutting the first fixing part unit with the second fixing part unit, the manufacturing method further includes:

[0018] Fill the first hollow area and the second hollow area with foam blocks.

[0019] In one embodiment, the step of winding the structure to be wound by the winding part specifically includes:

[0020] Perform an interleaved winding treatment on the structure to be wound by the winding part.

[0021] In one embodiment, the step of performing an interleaved winding treatment on the structure to be wound by the winding part includes:

[0022] Perform multiple winding treatments on the structure to be wound by the winding part;

[0023] There is an included angle between the winding directions of the winding part in two adjacent windings, so as to perform an interleaved winding treatment on the structure to be wound by the winding part.

[0024] In one embodiment, the step of assembling the fixing sleeve onto the semi-finished fixing part includes:

[0025] Perform a punching treatment on the semi-finished fixing part so that the semi-finished fixing part forms a connecting hole;

[0026] Install the fixing sleeve into the connecting hole.

[0027] In one of the embodiments, the step of punching the semi-finished fixing part specifically is: drilling the semi-finished fixing part.

[0028] A fixing part is manufactured by using the manufacturing method of the fixing part described in any one of the above embodiments.

[0029] A traction wearing assembly includes the above-mentioned fixing part.

[0030] Compared with the prior art, the present disclosure has at least the following advantages:

[0031] 1. In the above-mentioned manufacturing method of the fixing part, first, a first fixing part unit and a second fixing part unit are formed. A first hollow area is formed on the connecting surface of the first fixing part unit, and a first reinforcing rib is formed in the first hollow area. A second hollow area is formed on the connecting surface of the second fixing part unit, and a second reinforcing rib is formed in the second hollow area. Then, the first fixing part unit and the second fixing part unit are aligned and abutted, so that the first hollow area is communicated with the second hollow area, and the first reinforcing rib abuts against the second reinforcing rib to form a structure to be wound. Then, the structure to be wound is wound by a winding member to form a wound structure, so that the first fixing unit and the second fixing unit are reliably abutted in position, and at the same time, the first reinforcing rib and the second reinforcing rib are reliably abutted in position, improving the accuracy of subsequent heat setting, and at the same time making the fixing part; then, the wound structure is subjected to heat setting treatment to form a semi-finished fixing part, so that the winding member, the first fixing part unit and the second fixing part unit are reliably fixed and connected to each other; then, a fixing sleeve is assembled on the semi-finished fixing part.

[0032] 2. Since both the first fixing part unit and the second fixing part unit are hollow structures, and a first reinforcing rib is formed in the first hollow area and a second reinforcing rib is formed in the second hollow area, it not only increases the structural strength of the formed fixing part, but also reduces the carbon fiber material used under the same structural strength requirement, and reduces the assembly difficulty of the fixing sleeve.

[0048] To facilitate the understanding of the present disclosure, the present disclosure will be described more comprehensively below with reference to the relevant accompanying drawings. The preferred embodiments of the present disclosure are shown in the drawings. However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure content of the present disclosure more thorough and comprehensive.

[0049] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only embodiments.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present disclosure belongs. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0051] The present disclosure provides a manufacturing method of a fixing member, including: forming a first fixing member unit and a second fixing member unit, a first hollowed-out area is formed on the connecting surface of the first fixing member unit, and a first reinforcing rib is formed in the first hollowed-out area, a second hollowed-out area is formed on the connecting surface of the second fixing member unit, and a second reinforcing rib is formed in the second hollowed-out area; aligning and abutting the first fixing member unit and the second fixing member unit, so that the first hollowed-out area is communicated with the second hollowed-out area, and the first reinforcing rib abuts against the second reinforcing rib to form a structure to be wound; performing a winding process on the structure to be wound by a winding member to form a winding structure; performing a heat setting process on the winding structure to form a semi-finished fixing member; assembling a fixing sleeve on the semi-finished fixing member.

[0052] The above-mentioned method for manufacturing a fixing member first forms a first fixing member unit and a second fixing member unit. A first hollow area is formed on the connecting surface of the first fixing member unit, and a first reinforcing rib is formed in the first hollow area. A second hollow area is formed on the connecting surface of the second fixing member unit, and a second reinforcing rib is formed in the second hollow area. Then, the first fixing member unit and the second fixing member unit are aligned and abutted against each other, so that the first hollow area communicates with the second hollow area, and the first reinforcing rib abuts against the second reinforcing rib to form a structure to be wound. Then, the structure to be wound is wound by a winding member to form a wound structure, so that the first fixing unit and the second fixing unit are reliably abutted against each other in position, and at the same time, the first reinforcing rib and the second reinforcing rib are reliably abutted against each other in position, improving the accuracy of subsequent heat setting, and at the same time forming the fixing member. Then, the wound structure is subjected to heat setting treatment to form a semi-finished fixing member, so that the winding member, the first fixing member unit and the second fixing member unit are reliably fixed and connected to each other. Then, a fixing sleeve is assembled on the semi-finished fixing member. When in use, a fixing nail is passed through the fixing sleeve to be fixed to the patient's skull. Since both the first fixing member unit and the second fixing member unit are hollow structures, and a first reinforcing rib is formed in the first hollow area and a second reinforcing rib is formed in the second hollow area, it not only increases the structural strength of the formed fixing member, but also reduces the carbon fiber material used under the same structural strength requirement, and reduces the assembly difficulty of the fixing sleeve.

[0053] To better understand the technical solutions and beneficial effects of the present disclosure, the following further describes the present disclosure in detail with specific embodiments:

[0054] As Figure 1 shown, the manufacturing method of a fixing member in an embodiment includes some or all of the following steps:

[0055] S101, forming a first fixing member unit and a second fixing member unit.

[0056] See also Figure 2 and Figure 3 simultaneously. In this embodiment, a first fixing member unit 122 and a second fixing member unit 124 are formed. Among them, a first hollow area 122a is formed on the connecting surface of the first fixing member unit 122, and a first reinforcing rib 1224 is formed in the first hollow area 122a, increasing the structural strength of the first fixing member unit 122 and at the same time reducing the weight of the first fixing member unit 122. A second hollow area 124a is formed on the connecting surface of the second fixing member unit 124, and a second reinforcing rib 1244 is formed in the second hollow area 124a, increasing the structural strength of the first fixing member unit 122 and at the same time reducing the weight of the first fixing member unit 122. In one embodiment, both the first fixing member unit and the second fixing member unit are made of carbon fiber material.

[0057] See also Figure 2 andFigure 3 , further, the steps of forming the first fixing member unit 122 and the second fixing member unit 124 are specifically as follows: the first fixing member unit 122 and the second fixing member unit 124 are formed by a mold. In this embodiment, the structures of the first fixing member unit 122 and the second fixing member unit 124 are the same to facilitate mass production of the fixing member 20. Further, the first reinforcing rib 1224 extends along the extending direction of the first hollow area 122a, that is, the extending direction of the first reinforcing rib 1224 is consistent with the extending direction of the first hollow area 122a. Similarly, the second reinforcing rib 1244 extends along the extending direction of the second hollow area 124a, that is, the extending direction of the second reinforcing rib 1244 is consistent with the extending direction of the second hollow area 124a.

[0058] S103, align and abut the first fixing member unit with the second fixing member unit to communicate the first hollow area with the second hollow area, and abut the first reinforcing rib with the second reinforcing rib to form a structure to be wound.

[0059] As Figures 4 to 5 shown, in this embodiment, align and abut the first fixing member unit 122 with the second fixing member unit 124, that is, set the first hollow area 122a opposite to the second hollow area 124a to communicate the first hollow area 122a with the second hollow area 124a, and abut the first reinforcing rib 1224 with the second reinforcing rib 1244 to form a structure to be wound, improving the assembly accuracy of the first fixing member unit 122 and the second fixing member unit 124.

[0060] S105, wind the structure to be wound with a winding member to form a wound structure;

[0061] See also Figures 6 to 8 , in this embodiment, wind the structure to be wound with a winding member 130 to form a wound structure, avoiding relative movement between the first fixing member unit 122 and the second fixing member unit 124, enabling the first fixing member unit 122 and the second fixing member unit 124 to be reliably aligned and abutted, and at the same time enabling the winding member 130 to reliably cover the outer surfaces of the first fixing member unit 122 and the second fixing member unit 124.

[0062] S107, perform heat setting treatment on the wound structure to form the semi-finished fixing member;

[0063] See also Figures 5a to 8, in this embodiment, the steps of thermosetting the winding structure are specifically as follows: performing hot pressing on the winding structure to reliably, tightly and firmly connect the connection surface of the first fixing member unit 122 with the connection surface of the second fixing member unit 124, and at the same time, reliably, tightly and firmly connect the first reinforcing rib 1224 with the second reinforcing rib 1244, so that the first fixing member unit 122 and the second fixing member unit 124 are connected into an integral structure, and the winding member 130 is cured by heat to form a wrapping layer, thereby forming the fixing member semi-finished product. Specifically, the winding member 130 is a carbon cloth, and the wrapping layer is a carbon cloth layer.

[0064] S109, assembling the fixing sleeve onto the fixing member semi-finished product.

[0065] See also Figures 6 to 8 , in this embodiment, the fixing sleeve 127 is assembled onto the fixing member semi-finished product. During use, the fixing nail 40 is passed through the fixing sleeve 127 to be fixed to the patient's skull, facilitating the installation and fixation of the fixing nail 40. Specifically, the fixing sleeve 127 is a metal part, and the metal part is a titanium alloy part, a stainless steel part or an aluminum alloy part. Further, the metal part is a titanium alloy part, enabling the fixing ring to better meet the needs of nuclear magnetic resonance detection, timely observing the infection situation inside the nail track, and making reasonable decisions for the treatment of the patient.

[0066] The above manufacturing method of the fixing member 20 first forms the first fixing member unit 122 and the second fixing member unit 124. A first hollow area 122a is formed on the connecting surface of the first fixing member unit 122, and a first reinforcing rib 1224 is formed in the first hollow area 122a. A second hollow area 124a is formed on the connecting surface of the second fixing member unit 124, and a second reinforcing rib 1244 is formed in the second hollow area 124a. Then, the first fixing member unit 122 and the second fixing member unit 124 are aligned and abutted against each other, so that the first hollow area 122a communicates with the second hollow area 124a, and the first reinforcing rib 1224 abuts against the second reinforcing rib 1244 to form a structure to be wound. Then, the structure to be wound is wound by the winding member 130 to form a wound structure, so that the first fixing unit and the second fixing unit are reliably abutted against each other in position, and at the same time, the first reinforcing rib 1224 and the second reinforcing rib 1244 are reliably abutted against each other in position, improving the accuracy of subsequent heat curing, and at the same time forming the fixing member 20. Then, the wound structure is subjected to heat curing treatment to form a semi-finished fixing member, so that the winding member 130, the first fixing member unit 122 and the second fixing member unit 124 are reliably fixedly connected to each other. Then, the fixing sleeve 127 is assembled to the semi-finished fixing member. Since both the first fixing member unit 122 and the second fixing member unit 124 are hollow structures, and a first reinforcing rib 1224 is formed in the first hollow area 122a and a second reinforcing rib 1244 is formed in the second hollow area 124a, it not only increases the structural strength of the formed fixing member 20, but also reduces the carbon fiber material used under the same structural strength requirement, and reduces the assembly difficulty of the fixing sleeve.

[0067] See also Figures 6 to 8 , in one embodiment, before the step S103 of aligning and abutting the first fixing member unit 122 and the second fixing member unit 124, the manufacturing method further includes: applying glue to the connecting surface of the first fixing member unit 122 and the connecting surface of the second fixing member unit 124, so that the connecting surface of the first fixing member unit 122 and the connecting surface of the second fixing member unit 124 can be reliably aligned and abutted for positioning, so as to better wind the structure to be wound by the winding member 130 subsequently. Further, the step of applying glue to the connecting surface of the first fixing member unit 122 and the connecting surface of the second fixing member unit 124 is specifically: applying glue to the connecting surface of the first fixing member unit 122 and the connecting surface of the second fixing member unit 124, and at the same time applying glue to the first reinforcing rib 1224 and the second reinforcing rib 1244. Thus, when the first fixing member unit 122 and the second fixing member unit 124 are aligned and abutted, the connecting surface of the first fixing member unit 122 and the connecting surface of the second fixing member unit 124 are adhesively bonded, and at the same time, the first reinforcing rib 1224 and the second reinforcing rib 1244 are adhesively bonded.

[0068] In one embodiment, the step of applying glue to the connecting surface of the first fixing member unit 122 and the connecting surface of the second fixing member unit 124 is specifically as follows: applying resin glue to the connecting surface of the first fixing member unit 122 and the connecting surface of the second fixing member unit 124, so that the connecting surface of the first fixing member unit 122 and the connecting surface of the second fixing member unit 124 are reliably glued, and at the same time, the connecting surface of the first fixing member unit 122 and the connecting surface of the second fixing member unit 124 are both reliably adhered to the glue. In this embodiment, the resin glue is resin glue for carbon fiber.

[0069] Also refer to Figures 6 to 8 , in one embodiment, the winding member 130 is a carbon cloth, so that the winding member 130 reliably wraps around the structure to be wound. In this embodiment, the carbon cloth is T1000 carbon cloth, so that the reliability of the carbon cloth in high-strength carbon fiber applications is relatively stable.

[0070] Also refer to Figures 6 to 8 , in this embodiment, both the first fixing member unit 122 and the second fixing member unit 124 are made of carbon fiber material. In one embodiment, before the step S103 of aligning and abutting the first fixing member unit 122 and the second fixing member unit 124, the manufacturing method further includes: filling the first hollow area 122a and the second hollow area 124a with foam blocks 150 to prevent the first fixing member unit 122 and the second fixing member unit 124 made of carbon fiber material from deforming during thermosetting molding, and at the same time increasing the contact area between the fixing sleeve 127 and the first fixing member unit 122 and the second fixing member unit 124 respectively, and improving the tensile strength and torsional strength of the fixing ring. In this embodiment, the foam block 150 is a foaming material.

[0071] Also refer to Figures 6 to 8 , further, the step of filling the first hollow area 122a and the second hollow area 124a with foam blocks 150 includes: first filling the first hollow area 122a and the second hollow area 124a with foaming glue; then covering the second fixing member unit 124 on the first fixing member unit 122. When the winding structure is subjected to thermosetting treatment, the foaming glue expands to fill the first hollow area 122a and the second hollow area 124a, forming the foam block 150.

[0072] In one embodiment, the step of winding the structure to be wound by the winding member 130 is specifically as follows: winding the structure to be wound by the winding member 130 in a staggered manner, that is, winding the structure to be wound by the winding member 130 in different carbon fiber wire directions in a staggered manner, so that the winding member 130 better wraps around the structure to be wound. In this embodiment, the winding member 130 is a carbon cloth.

[0073] In one embodiment, the step of performing interleaved winding on the structure to be wound by the winding member 130 is specifically as follows: The structure to be wound is wound multiple times by the winding member 130. In this embodiment, there is an included angle between the winding directions of the winding member 130 for two adjacent times, so as to perform interleaved winding on the structure to be wound by the winding member 130, enabling the winding member 130 to better cover the structure to be wound. In this embodiment, the winding member 130 winds the structure to be wound once at a first preset included angle with respect to the carbon fiber wire, and then the winding member 130 winds the structure to be wound once at a second preset included angle with respect to the carbon fiber wire,... Thus, each time the winding member 130 winds the structure to be wound once at a different preset included angle with respect to the carbon fiber wire, and multiple winding processes are performed.

[0074] See also Figure 1 、 Figures 6 to 8 In one embodiment, the step S109 of assembling the fixing sleeve 127 to the semi-finished fixing member includes: First, perform a punching process on the semi-finished fixing member to form a fixing hole 125a in the semi-finished fixing member; then install the fixing sleeve 127 into the fixing hole 125a, enabling the fixing sleeve 127 to be reliably assembled in the fixing hole 125a. In this embodiment, the number and positions of the punching can be flexibly set according to the needs of clinical fixation, and are not limited here. See also Figure 9 and Figure 9a For example, both the number of the fixing holes 125a and the number of the fixing nails 40 are six. Two of the fixing nails 40 are located above the ears on both sides of the patient's head 10, two of the fixing nails 40 are located on the facial side of the patient, and the other two fixing nails 40 are located at the posterior position of the patient's skull. The three on the left side and the three on the right side are symmetrically distributed, avoiding stress concentration during traction and affecting the fixation effect. The two fixing nails 40 and the six fixing holes 125a are arranged in one-to-one correspondence to complete the fixation of the fixing member 20 to the skull.

[0075] See also Figure 1 、 Figures 6 to 8, Further, the step of installing the fixing sleeve 127 into the fixing hole 125a is specifically as follows: thread the fixing sleeve 127 into the fixing hole 125a to detachably connect the fixing sleeve 127 to the semi-finished fixing part. Since both the first fixing part unit and the second fixing part unit are made of carbon fiber material and both have hollow areas inside, the contact area where the fixing sleeve is screwed into the fixing hole is small, so the resistance when the fixing sleeve is screwed into the fixing hole is small, reducing the assembly difficulty of the fixing sleeve. Of course, in other embodiments, it is not limited to the way of threading the fixing sleeve 127 into the fixing hole 125a to assemble the fixing sleeve 127. For example, the fixing sleeve 127 is inserted through the fixing hole 125a and glued. In this embodiment, the fixing sleeve 127 is bonded to the fixing hole 125a with resin glue.

[0076] As Figure 10 and Figure 11 shown, further, the fixing nail 40 is a self-tapping screw or a tapered screw. During the locking process, after the nail head is locked, a continuous torque force is provided and the screw does not displace. When the torque force exceeds the maximum bearing stress of the skull, the skull is damaged and the screw can continue to displace along the axial direction. In this embodiment, the fixing nail 40 includes a nail head 42 and a nail body 44 that are integrally formed. There is a step at the connection between the nail head and the nail body, that is, the diameter of the nail body is larger than the diameter of the nail head, which plays a limiting role to prevent the fixing nail 40 from piercing the compact bone. As Figure 11 shown, even further, the fixing nail 40 is a tapered screw and the nail head is a tapered head, and the tapered head is successively locked into the cortical bone, cancellous bone and cortical bone of the skull. To better study the force and displacement changes during the fixation of different screws, the present disclosure respectively conducts simulation analysis on the torque forces of the self-tapping screw and the tapered screw locked to the skull. Among them, as Figure 12 shown is the finite element analysis schematic diagram of the tapered screw successively locked into the cortical bone, cancellous bone and cortical bone of the skull. Through simulation analysis, the force and displacement change diagram during the screw fixation as shown in Figure 13 is obtained. Among them, S1 is the force and displacement change diagram during the screw fixation corresponding to the self-tapping screw, and S2 is the force and displacement change diagram during the screw fixation corresponding to the tapered screw. Combining Figure 13 for analysis, it can be known that as the displacement inside the nail head and the skull increases, the tapered screw needs to provide a larger torsion force during fixation; for the tapered screw, the step and the tapered head are used for limiting to prevent the fixing nail 40 from piercing the compact bone.

[0077] In one of the embodiments, the step of drilling holes in the semi-finished fixing part is specifically: drilling holes in the semi-finished fixing part.

[0078] See also Figures 6 to 8, this application also provides a fixing member 20, which is manufactured by using the manufacturing method of the fixing member 20 described in any of the above embodiments.

[0079] For the above-mentioned fixing member 20, during manufacturing, a first fixing member unit 122 and a second fixing member unit 124 are first formed. A first hollow area 122a is formed on the connection surface of the first fixing member unit 122, and a first reinforcing rib 1224 is formed in the first hollow area 122a. A second hollow area 124a is formed on the connection surface of the second fixing member unit 124, and a second reinforcing rib 1244 is formed in the second hollow area 124a. Then, the first fixing member unit 122 and the second fixing member unit 124 are aligned and abutted against each other, so that the first hollow area 122a communicates with the second hollow area 124a, and the first reinforcing rib 1224 abuts against the second reinforcing rib 1244 to form a structure to be wound. Then, the structure to be wound is wound by a winding member 130 to form a wound structure, so that the first fixing unit and the second fixing unit are reliably butted against each other, and at the same time, the first reinforcing rib 1224 and the second reinforcing rib 1244 are reliably butted against each other, improving the accuracy of subsequent heat curing. At the same time, the fixing member 20; then, the wound structure is heat-cured to form a semi-finished fixing member, so that the winding member 130, the first fixing member unit 122 and the second fixing member unit 124 are reliably fixed and connected to each other in pairs; then, the fixing sleeve 127 is assembled on the semi-finished fixing member. During use, the fixing nail 40 is inserted through the fixing sleeve 127 to be fixed to the patient's skull; since both the first fixing member unit 122 and the second fixing member unit 124 are hollow structures, and the first reinforcing rib 1224 is formed in the first hollow area 122a, and the second reinforcing rib 1244 is formed in the second hollow area 124a, it not only increases the structural strength of the formed fixing member 20, but also reduces the carbon fiber material used under the same structural strength requirement.

[0080] Such as Figure 6 And Figure 7As shown, further, the fixing member 20 includes a carbon fiber member 120. The carbon fiber member 120 includes a first bending portion 120a, a second bending portion 120b, and a third bending portion 120c that are connected in sequence. The first bending portion 120a, the second bending portion 120b, and the third bending portion 120c are an integrally formed structure. The first bending portion 120a and the second bending portion 120b bend towards each other. A hollow cavity 123 is formed in the carbon fiber member 120. The hollow cavity 123 extends to the first bending portion 120a, the second bending portion 120b, and the third bending portion 120c respectively. Reinforcing ribs 123a protrude in the hollow cavity 123. The carbon fiber member 120 is provided with fixing holes through which fixing nails 40 are installed in the nail tracks of the patient's skull. In this embodiment, the first bending portion 120a and the third bending portion 120c bend towards each other so that the fixing member 20 can be better worn on the patient's head through the fixing nails 40. Specifically, when worn, the first bending portion 120a and the third bending portion 120c respectively correspond to both sides of the head, and the second bending portion 120b corresponds to the facial side of the head.

[0081] For the above-mentioned fixing member 20, since the first bending portion 120a, the second bending portion 120b, and the third bending portion 120c are an integrally formed structure, and a hollow cavity 123 is formed in the carbon fiber member 120. The hollow cavity 123 extends to the first bending portion 120a, the second bending portion 120b, and the third bending portion 120c respectively. Reinforcing ribs 123a protrude in the hollow cavity 123, which not only increases the structural strength of the fixing member 20, but also reduces the carbon fiber material used under the same structural strength requirements.

[0082] As Figure 6 and Figure 7 shown, in one embodiment, the reinforcing ribs 123a are respectively provided on the first bending portion 120a, the second bending portion 120b, and the third bending portion 120c, so that each part of the fixing member 20 has good structural strength.

[0083] As Figure 6 and Figure 7 shown, in one embodiment, the reinforcing ribs 123a are respectively provided on the first bending portion 120a, the second bending portion 120b, and the third bending portion 120c, and the reinforcing ribs 123a divide the hollow cavity 123 into two cavities, so that each part of the fixing member 20 has better structural strength.

[0084] As Figures 4 to 5 shown, in one embodiment, the carbon fiber member 120 includes a first fixing member unit 122 and a second fixing member unit 124. Also refer to Figure 2 andFigure 3 On the connecting surface of the first fixing member unit 122, a first hollow area 122a is formed, and a first reinforcing rib 1224 is formed within the first hollow area 122a. On the connecting surface of the second fixing member unit 124, a second hollow area 124a is formed, and a second reinforcing rib 1244 is formed within the second hollow area 124a. The first hollow area 122a communicates with the second hollow area 124a to form a hollow cavity 123. The connecting surface of the first fixing member unit 122 is connected to the connecting surface of the second fixing member unit 124, and the first reinforcing rib 1224 is connected to the second reinforcing rib 1244 to form a reinforcing rib 123a.

[0085] As Figure 6 and Figure 7 shown, in one embodiment, foam blocks 150 are filled within both the first hollow area 122a and the second hollow area 124a to prevent the carbon fiber member 120 from deforming during solidification, and to improve the tensile strength and torsional strength of the fixing ring. In this embodiment, the material of the foam blocks 150 is a foaming material.

[0086] As Figures 5 to 7 shown, in one embodiment, the connecting surface of the first fixing member unit 122 is thermally fixed to the connecting surface of the second fixing member unit 124, and the first reinforcing rib 1224 is thermally fixed to the second reinforcing rib 1244, so that the first fixing member unit 122 and the second fixing member unit 124 are reliably fixedly connected, and at the same time, the structure of the fixing ring is relatively compact.

[0087] As Figures 7 to 8 shown, in one embodiment, the fixing member 20 further includes a wrapping layer 130 which is wrapped around the outer peripheral wall of the carbon fiber member 120, so that the wrapping layer 130 can better protect the outer wall of the carbon fiber member 120, and at the same time, it is beneficial for the first fixing member unit 122 and the second fixing member unit 124 to be reliably aligned and formed and connected. In this embodiment, the wrapping layer is a carbon cloth layer.

[0088] As Figures 7 to 8 shown, in one embodiment, the carbon fiber member 120 includes a carbon fiber member main body 125 and a fixing sleeve 127. The carbon fiber member main body 125 is provided with a fixing hole 125a, and the fixing sleeve 127 is inserted through the fixing hole and connected to the carbon fiber member 120. In this embodiment, the fixing sleeve 127 is press-fitted into the fixing hole with an interference fit. In other embodiments, the fixing sleeve 127 can also be snapped into the fixing hole by a snap connection method.

[0089] As Figures 7 to 8As shown, in one embodiment, the first hollow area 122a and the second hollow area 124a are both filled with a foam block 150. The fixing holes respectively penetrate through the main body of the fiber member and the foam member. The first hollow area 122a and the second hollow area 124a are both filled with the foam block 150, which prevents the carbon fiber member 120 from deforming during solidification, and at the same time increases the contact area between the fixing sleeve 127 and the fixing hole, improving the tensile strength and anti-torsion strength of the fixing ring.

[0090] As Figure 8 and Figure 9 shown, the present application also provides a traction wearing assembly 50, including the fixing member 20 described in any of the above embodiments. Further, the traction wearing assembly 50 includes a fixing nail 40 and the fixing member 20. The fixing member 20 is provided with a connection hole 12, and the fixing nail 40 is inserted into the connection hole 12, so that the fixing nail 40 is detachably connected to the fixing member 20, and the length of the fixing nail 40 fixed to the patient's skull is adjustable.

[0091] As Figures 7 to 8 shown, in one of the embodiments, the connection hole 12 is a threaded hole, and the fixing nail 40 is screwed into the connection hole 12, so that the fixing nail 40 is reliably detachably connected to the fixing member 20.

[0092] The installation process of the traction wearing assembly 50 is as follows:

[0093] 1. First, place the fixing member 20 at the pre-installation position on the patient's skull;

[0094] 2. Then, according to the preset nail placement requirements, select a suitable hole position and place the fixing nail 40 in the fixing sleeve 127;

[0095] 3. Then adjust the contact between the fixing nail and the patient's skin;

[0096] 4. Finally, drive the two fixing nails at the back of the skull into the skull, then drive the two fixing nails on the facial side into the skull, and finally drive the two fixing nails on both sides of the skull into the skull.

[0097] 5. Adjust each fixing nail to make each fixing nail in a locked state to complete the fixation.

[0098] Compared with the prior art, the present disclosure has at least the following advantages:

[0099] 1. For the above manufacturing method of the fixing member 20, first, the first fixing member unit 122 and the second fixing member unit 124 are formed. A first hollow area 122a is formed on the connecting surface of the first fixing member unit 122, and a first reinforcing rib 1224 is formed within the first hollow area 122a. A second hollow area 124a is formed on the connecting surface of the second fixing member unit 124, and a second reinforcing rib 1244 is formed within the second hollow area 124a. Then, the first fixing member unit 122 and the second fixing member unit 124 are aligned and abutted against each other, so that the first hollow area 122a communicates with the second hollow area 124a, and the first reinforcing rib 1224 abuts against the second reinforcing rib 1244 to form a structure to be wound. Then, the structure to be wound is wound by the winding member 130 to form a wound structure, enabling the first fixing unit and the second fixing unit to be reliably abutted against each other in position, and at the same time enabling the first reinforcing rib 1224 and the second reinforcing rib 1244 to be reliably abutted against each other in position, improving the accuracy of subsequent heat curing, and at the same time enabling the fixing member 20. Then, the wound structure is subjected to heat curing treatment to form a semi-finished fixing member, enabling the winding member 130, the first fixing member unit 122, and the second fixing member unit 124 to be reliably fixedly connected to each other integrally. Then, the fixing sleeve 127 is assembled to the semi-finished fixing member. When in use, the fixing nail 40 is inserted through the fixing sleeve 127 to be fixed to the patient's skull;

[0100] 2. Since both the first fixing member unit 122 and the second fixing member unit 124 are hollow structures, and a first reinforcing rib 1224 is formed within the first hollow area 122a and a second reinforcing rib 1244 is formed within the second hollow area 124a, it not only increases the structural strength of the formed fixing member 20, but also reduces the carbon fiber material used under the same structural strength requirement, and reduces the assembly difficulty of the fixing sleeve.

[0101] The above embodiments only represent several implementation manners of the present disclosure. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present disclosure patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several deformations and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent should be subject to the appended claims.
