Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a hip preserving treatment device and a hip preserving treatment kit. Background Art

[0002] Hip preservation therapy, as an important strategy for dealing with various hip diseases, aims to preserve the patient's own hip joint to the greatest extent possible and restore its function, thereby avoiding or delaying hip replacement surgery.

[0003] In current hip preservation treatments, support pins are typically placed through the cracks in the hip joint. When a person stands or walks, the hip joint bears the body's weight and the reaction force of the ground, so the support pins need to have good tensile and compressive properties. At the same time, if medication is administered to the affected area in a timely manner during treatment, it will improve blood circulation and promote bone cell regeneration. Therefore, many support pins are currently equipped with a drug delivery mechanism. Compared to conventional oral or intravenous injections, the setting of a drug delivery mechanism can more quickly and efficiently deliver drugs to the affected area of ​​the femoral head.

[0004] However, the current drug delivery mechanism usually includes a Luer connector at the tail end of the support nail, which is then connected to the infusion tube and the syringe. The infusion tube needs to be wrapped around the patient's thigh, and when in use, the drug is delivered to the inside of the hip joint through the syringe through the infusion tube. It can be seen that the drug delivery mechanism has many disadvantages. The operation of connecting the infusion tube is cumbersome. If there is any negligence during the connection process, the joint may not be sealed tightly, causing drug leakage and infection risks. In addition, the presence of an extracorporeal infusion tube not only causes inconvenience to the patient's movements, reduces comfort, and interferes with the recovery process, but is also prone to loosening or even falling off due to external pulling, affecting the continuity and stability of drug delivery, and ultimately having a negative impact on the treatment effect.

[0005] Furthermore, current research has shown that electrical stimulation can enhance cell proliferation, nerve repair, and reduce infection, and has been widely used in wound healing. However, there are currently few devices that apply electrical stimulation to the hip joint internally, and traditional treatment options all involve inserting wires into the intramedullary nail, which presents similar issues as infusion lines, such as infection risk, connection stability, and restrictions on patient activity.

DETAILED DESCRIPTION

[0038] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] The present invention discloses a hip preserving treatment device, such as Figures 1 to 4As shown. The hip-preserving treatment device of the present invention includes a cathode decomposition chamber 1 and an anode support pin 2 for penetrating a hip fracture. The anode support pin 2 has a receiving cavity within it and a first opening on its surface, the first opening communicating with the receiving cavity. The cathode decomposition chamber 1 has a drug storage cavity 3 filled with drug, and the cathode decomposition chamber 1 has a second opening communicating with the drug storage cavity 3. The anode support pin 2 also has an overflow hole 4 communicating with the receiving cavity. During surgery, the anode support pin 2 is first implanted into the human body, penetrating the hip fracture. Solid drug is then introduced into the drug storage cavity 3 through the second opening. Subsequently, the cathode decomposition chamber 1, containing the drug, is then introduced into the receiving cavity through the first opening. Due to the influence of human body temperature, the solid drug melts into a liquid state, and the drug, acting as an electrolyte, contacts the anode support pin 2 through the second opening. At this point, because both the cathode decomposition chamber 1 and the anode support pin 2 are in contact with the liquid drug, the drug, cathode decomposition chamber 1, and the anode support pin 2 cooperate to form a discharge structure, which discharges the drug using the principle of a galvanic cell. Since the anode support nail 2 has been implanted in the human hip joint at this time, the current released by the discharge structure can generate electrical stimulation to the tissue at the hip joint. This electrical stimulation can accelerate the proliferation and differentiation of tissue cells at the hip joint, promote the regeneration of nerve fibers, and help the functional recovery and damage repair of the hip joint. During the discharge process of the discharge structure, the cathode decomposition chamber 1 gradually decomposes, and the drug flows to the periphery of the anode support nail 2 through the overflow hole 4, that is, the drug flows to the outside of the anode support nail 2 through the overflow hole 4, so that the drug can flow into the tissue at the hip joint, improve the blood circulation of the tissue at the hip joint, and promote the regeneration of bone cells. The hip-preserving treatment device of the present invention has a simple structure, which not only fixes the cracks at the hip joint, but also realizes drug supply and current stimulation to the tissue at the hip joint, without the need to set up infusion tubes and wires outside the body, thereby reducing the risk of infection caused by infusion tubes.

[0042] In the hip-preserving treatment device of the present invention, various technical features, such as the specific shape of the anode support pin 2 and the location of the overflow hole 4, have multiple implementation options. Below, we will describe in detail one implementation of each of these features, and this implementation will be referred to as the present embodiment. Other implementations of various features, such as the specific shape of the anode support pin 2, are referred to as alternative embodiments, and these alternative embodiments are briefly described below.

[0043] In this embodiment, if Figure 1 and Figure 2As shown, the cathode decomposition chamber 1 is made of chemically active magnesium, and the anode support pin 2 is made of titanium alloy. Titanium alloy has good compatibility with human tissue and does not cause an immune response. Furthermore, due to the high chemical activity of magnesium, the drug serving as the electrolyte undergoes a rapid redox reaction upon contact with the cathode decomposition chamber 1 and the anode support pin 2, respectively. As the redox reaction progresses, fine cracks gradually appear on the surface of the cathode decomposition chamber 1 and continue to expand. Once the reaction is complete, the cathode decomposition chamber 1 is completely dissolved. The drug stored in the cathode decomposition chamber 1 diffuses into the hip joint through the overflow hole 4, treating the affected area. Some magnesium metal also flows into the hip joint along with the drug. As an essential element for the human body, magnesium metal is harmless to the body. Simultaneously, the discharge structural reaction generates an electrical stimulation of approximately 2.8V, promoting the growth and healing of nerves and tissues in the hip joint. By limiting the materials of the cathode decomposition chamber 1 and the anode support pin 2, the present invention effectively discharges the tissues in the hip joint, while also being harmless to the human body during the decomposition process of the cathode decomposition chamber 1. In other embodiments, the cathode decomposition chamber 1 may also be made of metal zinc, which is more active.

[0044] In this embodiment, if Figure 1 and Figure 5As shown, the side wall of the anode support nail 2 is provided with a compression zone and a tensile zone that are symmetrically arranged along the axis of the anode support nail 2. A compression portion 5 is provided in the compression zone, and a tensile portion 6 is provided in the tensile zone. Both the compression portion 5 and the tensile portion 6 are in an "eight" shape. The "eight" opening of the compression portion 5 is arranged toward the nail head of the anode support nail 2, and the "eight" opening of the tensile portion 6 is arranged toward the nail tail of the anode support nail 2. When the anode support nail 2 is implanted in the hip joint, the tensile portion 6 is arranged toward the side of the human head, and the compression portion 5 is arranged toward the side of the human foot. The arrangement of the compression portion 5 and the tensile portion 6 is because after the anode support nail 2 is implanted in the hip joint, when the human body stands or walks, tensile stress and tensile stress are generated in the bones of the hip joint. Specifically, at the hip joint, when a person stands or walks, the hip joint bears the body's weight and the reaction force of the ground. These forces cause the bones at the hip joint to bend and deform, generating tensile stress on the outside of the bones at the hip joint and tensile stress on the inside of the bones at the hip joint. Both tensile and tensile stresses may cause the anode support nail 2 to loosen or break. Therefore, a compressive portion 5 is required to relieve tensile stress, thereby improving the compressive resistance of the anode support nail 2. A tensile portion 6 is provided to relieve tensile stress, thereby improving the tensile resistance of the anode support nail 2. The curved shape of the compressive portion 5 and the tensile portion 6 effectively relieves the corresponding stresses. Since the direction of the tensile stress is opposite to the direction of the tensile stress, the curved opening of the compressive portion 5 and the tensile portion 6 face opposite directions. The present invention enhances the compressive and tensile resistance of the anode support nail 2 by providing the compressive portion 5 and the tensile portion 6. In other embodiments, the shape of the pressure-resistant part 5 and the shape of the tensile part 6 can also adopt other shapes, such as the pressure-resistant part 5 and the tensile part 6 can both be set to semicircular arc shape, and the semicircular arc openings of the pressure-resistant part 5 and the tensile part 6 are in opposite directions.

[0045] In this embodiment, if Figure 1 and Figure 5 As shown, the anti-compression portion 5 and the anti-tensile portion 6 are both in the shape of an eight-shaped hole, and both the anti-compression portion 5 and the anti-tensile portion 6 are connected to the accommodating cavity. Therefore, the drug stored in the cathode decomposition chamber 1 will also diffuse into the hip joint through the anti-compression portion 5 and the anti-tensile portion 6. At the same time, when the anode support pin 2 is implanted in the human body, the fixed constraint of the anode support pin 2 and the vicinity of the load application point are often stress concentration areas. Therefore, by providing the curved anti-compression portion 5 and the curved anti-tensile portion 6, the force transmission path can be effectively changed, so that the force can be more evenly distributed to different parts of the anode support pin 2, avoiding excessive local stress in the anode support pin 2, which may lead to breakage. In other embodiments, the anti-compression portion 5 and the anti-tensile portion 6 can also be provided on the outer surface of the anode support pin 2 in the form of reinforcing ribs. In this case, the support strength of the anode support pin 2 is enhanced, but the drug can only flow to the hip joint through the overflow hole 4.

[0046] In this embodiment, although the compression portion 5 and the tension portion 6 are both configured as an eight-shaped hole to increase the channel for drug outflow, the support strength of the anode support nail 2 is reduced. Figure 1 and Figure 2 As shown, the hip-preserving treatment device of the present invention also includes a support portion, which is provided to support the anode support pin 2 and prevent excessive deformation. A cavity for accommodating the support portion is provided on the side wall of the anode support pin 2, and the cavity communicates with the accommodating chamber. The support portion is located between the side wall of the anode support pin 2 and the cathode decomposition chamber 1. The support portion has a first state and a second state. When in the first state, the support portion is linear along the length of the anode support pin 2. When in the second state, the support portion is arcuate along the length of the anode support pin 2, with the arcuate opening facing the cathode decomposition chamber 1. Typically, the anode support pin 2 is implanted in the human body, and then the support portion in the first state is placed into the accommodating chamber. The cathode decomposition chamber 1 is then placed into the accommodating chamber, so that the support portion is located between the side wall of the anode support pin 2 and the cathode decomposition chamber 1. Finally, an external force is applied to the support portion to cause it to deform from the first state to the second state. This means that the external force transforms the linear support portion into an arcuate support portion along the length of the anode support pin 2. In some cases, the support portion can be changed from the first state to the second state without the use of external force. For example, when the support portion is made of a memory alloy, the support portion can sense human body temperature, causing the temperature of the support portion to change and deform. The present invention provides a support portion, and the support portion can be changed from a straight line to an arc shape along the length of the anode support nail 2. This facilitates the installation of the cathode decomposition chamber 1 while effectively enhancing the support strength of the anode support nail 2. In other embodiments, the support portion can be omitted, provided that the anode support nail 2 is provided with a compression portion 5 in the shape of an octave hole and a tension portion 6 in the shape of an octave hole. However, in order to enhance the support strength of the anode support nail 2, a microstructure needs to be added to the accommodating cavity, such as a plurality of lattice structures. In this case, the anode support nail 2 needs to be manufactured using 3D printing. However, the support effect and ease of use of 3D-printed anode support nails 2 are currently inferior to the combination of the anode support nail 2 and the support portion.

[0047] In this embodiment, if Figures 6 to 8As shown, the support portion is a mesh tube 7, which is sleeved onto the exterior of the cathode decomposition chamber 1. The mesh tube 7 is composed of several meshes. The mesh structure within the mesh tube 7 is designed based on the tensile and tensile stresses to which the anode support pin 2 is subjected. The meshes are denser near the compression portion 5, while the meshes are more sparse near the tensile portion 6. When the mesh tube 7 enters the second state, its radial length increases, meaning it expands. This expansion provides support for the anode support pin 2, preventing it from excessive deformation. Furthermore, the mesh tube 7 is made of a conductive metal material. Due to gravity, the drug will flow downward during release, resulting in uneven drug release. The mesh tube 7 not only supports the anode support pin 2, but also, due to its mesh structure, when electrolysis in the cathode decomposition chamber 1 generates current, current also flows through the mesh tube 7. This current attracts anions in the drug, resulting in uniform drug release across all axial regions of the anode support pin 2. Furthermore, when the mesh tube 7 changes to the second state, i.e., when the mesh tube 7 expands, the anode support pin 2 deforms slightly. Because the mesh within the mesh tube 7 is not uniformly arranged, the radial cross-section of the anode support pin 2 changes from a circular shape to an elliptical shape when the mesh tube 7 expands, thereby enhancing the anode support pin 2's anti-rotation effect. Furthermore, although the anode support pin 2 deforms slightly after the mesh tube 7 expands, the small deformation does not affect its removal from the human body. By configuring the support portion as the mesh tube 7, the present invention facilitates the installation of the support portion and the cathode decomposition chamber 1. By employing a non-uniform mesh design for the mesh tube 7, the compressive and tensile properties of the anode support pin 2 are improved. By constructing the mesh tube 7 from metal, the drug release is enhanced. In other embodiments, the support portion may also be a metal strip.

[0048] In this embodiment, if Figure 3 and Figure 4 As shown, the head of the anode support nail 2 is provided with an anti-rotation drill 17, and an overflow hole 4 is provided on the head of the anode support nail 2. Specifically, the overflow hole 4 is provided on the anti-rotation drill 17. The provision of the anti-rotation drill 17 prevents the anode support nail 2 from rotating freely during installation in the human body, thereby preventing the compression portion 5 and the tension portion 6 from being positioned in their designated positions. In other words, it prevents the tension portion 6 from deviating from its position toward the human head. The present invention prevents the anode support nail 2 from rotating freely by providing the anti-rotation drill 17. In other embodiments, threads may be provided on the entire outer wall of the anode support nail 2. When drilling a hole at the hip joint, tapping is performed simultaneously, and the anode support nail 2 is then screwed into the hip joint.

[0049] In this embodiment, if Figures 1 to 4As shown, the overflow hole 4 is set away from the second opening, that is, the overflow hole 4 is not directly connected to the second opening, so as to prevent the discharge structure from being fully discharged but the liquid medicine from flowing out of the overflow hole 4 too early. In other embodiments, the overflow hole 4 can also be set to be directly connected to the second opening, but in this case, a degradable film that closes the second opening needs to be provided on the cathode decomposition chamber 1, and spikes for piercing the degradable film are provided on the inner wall of the accommodating chamber, and the spikes are also made of titanium alloy. When the cathode decomposition chamber 1 enters the accommodating chamber, the spikes pierce the degradable film. At this time, since the degradable film has not decomposed, the degradable film blocks the second opening and the overflow hole 4. With the continuous discharge reaction of the spikes, the medicine, and the cathode decomposition chamber 1, the degradable film is also continuously decomposed, and then the medicine can continuously flow out of the overflow hole 4.

[0050] In this embodiment, if Figures 7 to 10 As shown, the hip-preserving treatment device of the present invention includes a support, which includes a support body 8, a first fixing hole provided in the support body 8, a second fixing hole provided in the support body 8, a locking screw 9 extending through the first fixing hole, and an anode support pin 2 extending through the second fixing hole. To connect a first bone 18 and a second bone 19 that have been split, the hip-preserving treatment device of the present invention first drills holes in the first bone 18 and the second bone 19, then secures the support body 8 at the corresponding mounting positions on the first bone 18. The locking screw 9 is then passed through the first fixing hole and secured to the first bone 18. Finally, the anode support pin 2 is passed through the second fixing hole, thereby simultaneously connecting the first bone 18 and the second bone 19. The provision of the support in the present invention allows the anode support pin 2 to securely connect the first bone 18 and the second bone 19. In other embodiments, the support of this embodiment may be omitted when fixing holes are drilled in the first bone 18 and the second bone 19 to accommodate the anode support pin 2, the fixing holes are tapped, and threads are provided on the outer wall of the anode support pin 2 to mate with the fixing holes.

[0051] In this embodiment, if Figure 2 、 Figure 3 、 Figures 9 to 11As shown, the support body 8 includes a support pin fixing tube 8a and a locking screw fixing plate 8b connected to the first end of the support pin fixing tube 8a. A first fixing hole is provided in the screw fixing plate 8b, and a second fixing hole is provided in the support pin fixing tube 8a. The outer wall of the anode support pin 2 is provided with a stepped surface, and the second fixing hole is provided with a blocking portion 15 that cooperates with the stepped surface. The blocking portion 15 is provided at the second end of the support pin fixing tube 8a. During use of the hip-preserving treatment device of the present invention, the anode support pin 2 is inserted from the first end of the support pin fixing tube 8a into the second fixing hole. As the anode support pin 2 continues to move toward the second end of the support pin fixing tube 8a, the blocking portion 15 eventually contacts the stepped surface, thereby restricting the anode support pin 2 from moving toward the second end of the support pin fixing tube 8a. By providing the stepped surface on the outer wall of the anode support pin 2 and the blocking portion 15 at the second end of the support pin fixing tube 8a, the present invention effectively prevents the anode support pin 2 from deviating from the predetermined surgical position. In other embodiments, a limit block may be provided on the anode support pin 2, and a limit groove cooperating with the limit block may be provided on the support pin fixing tube 8a, wherein the limit groove extends to the first end of the support pin fixing tube 8a.

[0052] Based on the hip-preserving treatment device of the embodiment described above, the hip-preserving treatment device of the present invention can be divided into two types. One is a non-replenishable hip-preserving treatment device, in which the medicine in the cathode decomposition chamber 1 cannot be replenished. This hip-preserving treatment device is described in detail below using Example 1 as an example. The other is a replenishable hip-preserving treatment device, in which the cathode decomposition chamber 1 can be continuously replenished inside the anode support pin 2. This hip-preserving treatment device is described in detail below using Example 2 as an example.

[0053] Example 1:

[0054] like Figure 1 、 Figure 2 、 Figure 5 and Figure 12As shown, the hip-preserving treatment device in Example 1 includes a first sealing member, which includes a first abutting portion 10 and a first sealing member 11 connected to the first abutting portion 10. After the cathode decomposition chamber 1 is installed in the accommodating chamber, the second opening is set toward the head of the anode support pin 2, and the mesh tube 7 is installed in the accommodating chamber and expanded, the first sealing member is installed. In Example 1, the first sealing member 11 is provided with a first external thread, and the first end of the support pin fixing tube 8a is provided with a first internal thread 20 that matches the first external thread. During the installation of the first sealing member, the first abutting portion 10 is extended into the accommodating chamber, and the first sealing member is driven to move toward the head of the anode support pin 2. The first external thread and the first internal thread 20 are continuously engaged until the first abutting portion 10 abuts the cathode decomposition chamber 1, so that the cathode decomposition chamber 1 is fixed relative to the anode support pin 2. At this time, due to the abutment of the first abutting portion 10, the drug is fully in contact with the anode support pin 2, and the discharge structure is fully discharged. At the same time, when the first abutting portion 10 abuts the cathode decomposition chamber 1, the first sealing portion 11 completely seals the first opening. Furthermore, the first sealing portion 11 is threadedly connected to the support body 8, preventing external bacteria from entering the anode support nail 2 through the first opening. The present invention, through the provision of the first abutting portion 10 and the first sealing portion 11, prevents external bacteria from entering the interior of the anode support nail 2 while allowing the discharge structure to fully discharge.

[0055] Example 2:

[0056] like Figures 13 to 16As shown, the hip preserving treatment device in Example 2 also includes a dosing tube 12 and a second closure member. The dosing tube 12 is arranged on one side of the tail of the anode support pin 2, and the dosing tube 12 is connected to the first opening. In detail, the first end of the dosing tube 12 is provided with a second external thread 21, and the first end of the support pin fixing tube 8a is provided with a first internal thread 20 that matches the second external thread 21. After the mesh tube 7 is installed in the accommodating cavity and the mesh tube 7 is expanded, the first end of the dosing tube 12 is installed on the support pin fixing tube 8a through the engagement of the first internal thread 20 and the second external thread 21. At this time, the first end of the dosing tube 12 is connected to the first opening. The second closure member includes a second abutting portion 13 and a second closure portion 14 connected to the second abutting portion 13. The first end of the second abutting portion 13 is used to abut the cathode decomposition chamber 1. The second end of the second abutting portion 13 is provided with a third external thread 22, and the second end of the second abutting portion 13 is connected to the second sealing portion 14. The inner wall of the second end of the dosing tube 12 is provided with a third internal thread 23 that matches the third external thread 22. After the dosing tube 12 is installed on the support pin fixing tube 8a, the cathode decomposition chamber 1 is inserted into the dosing tube 12 from the second end. The cathode decomposition chamber 1 enters the accommodating cavity through the internal pipe of the dosing tube 12, and the second opening is arranged toward the nail head of the anode support nail 2. Then, the second abutting portion 13 is also inserted into the dosing tube 12 from the second end and moved toward the nail head of the anode support nail 2. At the same time, the third external thread 22 is driven to cooperate with the third internal thread 23, and the second closing part 14 is continuously rotated until the second abutting part 13 is located in the dosing tube 12 and the accommodating chamber, and the first end of the second abutting part 13 abuts the cathode decomposition chamber 1, and the second closing part 14 covers the opening of the second end of the dosing tube 12. When the cathode decomposition chamber 1 in the accommodating chamber is completely decomposed and it is necessary to replenish the medicine, the second closing part is separated from the dosing tube 12, and then a cathode decomposition chamber 1 is dropped into the accommodating chamber from the second end of the dosing tube 12. Through the arrangement of the dosing tube 12 and the second closing part, the second abutting part 13 can abut the cathode decomposition chamber 1, so that the cathode decomposition chamber 1 can be fixed, which facilitates the full discharge of the discharge structure; at the same time, the second closing part 14 covers the opening of the second end of the dosing tube 12 to prevent bacteria from entering the human body; in addition, the postoperative support and the anode support nail 2 are located in the body, and the dosing tube 12 is exposed on the skin surface, which facilitates the replenishment of medicine. In addition, if it is necessary to speed up the decomposition speed of the cathode decomposition chamber 1, an external power supply, such as a 3.3-volt dry battery, can be provided. The positive pole of the external power supply is electrically connected to the cathode decomposition chamber 1 through a first wire, and the negative pole of the external power supply is electrically connected to the anode support nail 2 through a second wire. The first wire passes through the inside of the second supporting portion 13 and extends to the outside of the second closed portion 14. The second wire passes through the inner wall of the dosing tube 12 and extends to the outer wall of the dosing tube 12 located outside the human body.

[0057] The present invention also discloses a hip preservation treatment kit, such as Figure 3 、 Figures 6 to 8 、 Figure 12 and Figure 17 As shown, a hip preserving treatment kit of the present invention includes a first handle 16, a second handle 24, a third handle 25, a fourth handle, and the hip preserving treatment devices described in the first and second embodiments above.

[0058] The first handle 16 is used to cooperate with the anode support nail 2. Specifically, Figure 2 and 3 As shown. The anode support nail 2 has a first connecting portion at its tail, and a second connecting portion is provided on the first handle 16 to mate with the first connecting portion. In this embodiment, the first connecting portion comprises three slots, and the second connecting portion comprises three protrusions that mate with the three slots. A fourth external thread 26 is provided on the outer wall of the tail of the anode support nail 2 to mate with the first internal thread 20. After the first and second connecting portions mate, that is, after the first handle 16 mates with the anode support nail 2, the first handle 16 is rotated to screw the anode support nail 2 into the support nail fixing tube 8a. In other embodiments, the first and second connecting portions may also be configured as magnets and iron blocks.

[0059] The second handle 24 is used to cooperate with the mesh tube 7. Specifically, Figures 6 to 8 、 Figure 12 As shown. A third connecting portion is provided at one end of the mesh tube 7, and a fourth connecting portion is provided on the second handle 24 to mate with the third connecting portion. In this embodiment, the third connecting portion is a cylindrical block, with a fifth external thread 27 provided on the outer wall of the cylindrical block, and a fifth internal thread mates with the fifth external thread 27 on the inner wall of the accommodating chamber. A first spline groove is provided on the side of the cylindrical block away from the mesh tube 7, and the fourth connecting portion is a first spline 28. The first spline 28 mates with the first spline groove, thereby mates the second handle 24 with the mesh tube 7. Holding the second handle 24, the mesh tube 7 is inserted into the accommodating chamber, and the fifth external thread 27 engages with the fifth internal thread. Rotating the second handle 24 drives the mesh tube 7 toward the tail of the anode support nail 2, with the end of the mesh tube 7 away from the second handle 24 resting against the inner wall of the accommodating chamber. As the second handle 24 continues to rotate, the mesh tube 7 expands and deforms. In other embodiments, the third and fourth connecting portions may also be connected using a snap-fit ​​connection.

[0060] The third handle 25 is matched with the dosing tube 12. Specifically, Figures 14 to 17As shown. In this embodiment, the radial cross-section of the dosing tube 12 is plum blossom-shaped, and the third handle 25 is provided with a first plum blossom groove 29 that cooperates with the dosing tube 12. When the dosing tube 12 needs to be fixed to the support nail fixing tube 8a, the dosing tube 12 is inserted into the first plum blossom groove 29 to complete the engagement of the third handle 25 with the second end of the dosing tube 12. The third handle 25 is then rotated to engage the first internal thread 20 and the second external thread 21. In other embodiments, the radial cross-section of the dosing tube 12 may also be hexagonal, and the third handle 25 may be provided with a hexagonal groove that cooperates with the dosing tube 12.

[0061] The fourth handle cooperates with the first closing member. Figure 1 、 Figure 2 and Figure 5 As shown. In this embodiment, a second hexagonal groove 30 is provided on the side of the first closing portion 11 away from the first abutting portion 10, and a hexagonal protrusion is provided on the fourth handle to cooperate with the second hexagonal groove 30. After the hexagonal protrusion cooperates with the second hexagonal groove 30, that is, after the fourth handle cooperates with the first closing member, the fourth handle is rotated to screw the first closing portion 11 into the support pin fixing tube 8a. In other embodiments, the second hexagonal groove 30 may also be a rectangular groove, and the fourth handle may also be provided with a rectangular protrusion to cooperate with the rectangular groove.

[0062] like Figures 1 to 17 As shown, the method of using the hip preservation treatment kit of the present invention is as follows:

[0063] In S1, a hole is drilled through the bone at the patient's hip joint, extending through the fracture. After S1, S2 is performed.

[0064] S2, fix the support body 8 to the first bone 18 by means of the locking screw 9. After S2 is completed, proceed to S3.

[0065] In step S3, the first handle 16 is engaged with the anode support pin 2 and driven, forcing the anode support pin 2 into the implant hole. The anode support pin 2 penetrates the bone fracture at the hip joint. The first handle 16 is then rotated, engaging the first internal thread 20 with the fourth external thread 26 until the stepped surface abuts against the blocking portion 15. The first handle 16 is then separated from the anode support pin 2. After step S3 is completed, proceed to step S4.

[0066] In step S4, the second handle 24 is engaged with the mesh tube 7. The second handle 24 is driven to place the mesh tube 7, which is in the first state, into the receiving cavity, maintaining a gap between the mesh tube 7 in the first state and the sidewall of the anode support pin 2. The second handle 24 is rotated to engage the fifth external thread 27 with the fifth internal thread. As the second handle 24 is rotated, the mesh tube 7 gradually expands and enters the second state. Because the fifth external thread 27 engages the fifth internal thread, the mesh tube 7 is unlikely to leave the receiving cavity. The second handle 24 is then separated from the mesh tube 7. After completing step S4, proceed to step S5 or S7.

[0067] In step S5, mate the third handle 25 with the dosing tube 12 and rotate it to engage the first internal thread 20 and the second external thread 21, thereby connecting the dosing tube 12 to the support pin fixing tube 8a. After the dosing tube 12 and the support pin fixing tube 8a are connected, separate the third handle 25 from the dosing tube 12. After completing step S5, proceed to step S6.

[0068] In step S6, the cathode decomposition chamber 1 is placed into the accommodating chamber through the dosing tube 12. The second sealing member is then manually screwed into the dosing tube 12. When additional dosing is required, the second sealing member is separated from the dosing tube 12. The cathode decomposition chamber 1 is then placed back into the accommodating chamber, and the second sealing member is again re-engaged to seal the dosing tube 12. After step S6 is completed, proceed to step S8.

[0069] In step S7, the cathode decomposition chamber 1 is placed into the accommodating chamber through the first opening. The fourth handle is then engaged with the first closure member. The fourth handle is rotated to engage the first external thread with the first internal thread 20 until the first closure member is secured to the support pin fixing tube 8a. The fourth handle is then separated from the first closure member. After step S7 is completed, proceed to step S8.

[0070] S8. After the patient's hip joint heals, the hip preserving treatment device is removed from the patient's body.

[0071] In summary, the hip-preserving treatment device of the present invention has a simple structure. It not only fixes hip joint fractures but also delivers medication and electrical stimulation to hip joint tissue without requiring external infusion tubes and wires. Furthermore, by specifying the materials of the cathode decomposition chamber 1 and the anode support pin 2, effective discharge is achieved in hip joint tissue, while the decomposition process of the cathode decomposition chamber 1 is harmless to the human body. Furthermore, the design of the compression-resistant portion 5 and the tensile-resistant portion 6 enhances the compressive and tensile resistance of the anode support pin 2. Furthermore, by designing the compression-resistant portion 5 and the tensile-resistant portion 6 as a figure-eight hole, medication can flow out of the compression-resistant portion 5 and the tensile-resistant portion 6 while reducing stress concentration on the anode support pin 2. Furthermore, the support portion effectively enhances the support strength of the anode support pin 2. The support portion is constructed as a mesh tube 7, facilitating installation of the support portion and the cathode decomposition chamber 1. The non-uniform mesh design of the mesh tube 7 improves the compressive and tensile resistance of the anode support pin 2. The metal design of the mesh tube 7 facilitates drug release. The anti-rotation drill 17 prevents the anode support pin 2 from rotating freely. The overflow hole 4 is positioned away from the second opening to prevent liquid medication from prematurely escaping from the overflow hole 4. The support allows the anode support pin 2 to securely connect the split first bone 18 and second bone 19. The blocking portion 15 and the stepped surface prevent the anode support pin 2 from deviating from the intended surgical position. The first abutting portion 10 and the first sealing portion 11 prevent external bacteria from entering the anode support pin 2 while ensuring sufficient discharge of the discharge structure. The dosing tube 12 and the second sealing member facilitate sufficient discharge of the discharge structure, facilitate medication replenishment, and prevent bacteria from entering the human body.

[0072] It should be emphasized that the above are only preferred embodiments of the present invention and do not limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
