Description

Technical Field

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

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

[0003] During the current hip-preserving treatment process, support nails are usually set to penetrate the cracks of the hip joint. When a person stands or walks, the hip joint bears the weight of the body and the reaction force from the ground. Therefore, the support nails need to have good tensile and compressive properties. At the same time, during the treatment process, if drugs are administered to the affected area in a timely manner, it will improve blood circulation and promote bone cell regeneration. Therefore, many current support nails are accompanied by a drug delivery mechanism. The setting of the drug delivery mechanism can make the drug reach the lesion area of the femoral head more quickly and efficiently compared with conventional oral or intravenous injection.

[0004] However, the current drug delivery mechanism usually includes setting a Luer connector at the tail section of the support nail. The Luer connector is then connected to an infusion tube and a syringe. The infusion tube needs to be wound around the patient's thigh. When in use, the drug is delivered into the hip joint through the infusion tube by the syringe. It can be seen that the drug delivery mechanism has many drawbacks. The operation of connecting the infusion tube is cumbersome. If there is a slight negligence during the connection process, the joint may not be tightly sealed, leading to the risks of drug leakage and infection. In addition, the presence of the external infusion tube not only causes inconvenience to the patient's movement, reduces comfort, interferes with the rehabilitation process, but also easily causes the connection between the infusion tube and the intramedullary nail to become loose or even fall off due to external pulling, affecting the continuity and stability of drug delivery, and ultimately having a negative impact on the treatment effect.

[0005] In addition, current research has proven that electrical stimulation can enhance cell proliferation, nerve repair, and reduce infection, and has been widely used in wound healing. However, there are few devices for applying electrical current stimulation inside the hip joint at present, and the current traditional treatment plans all set wires entering the intramedullary nail, which also have problems similar to those of the infusion tube, such as the risk of infection, connection stability, and restrictions on patient movement. Summary of the Invention

[0020] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments.

In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0022] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", "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 directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations. In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0023] The present invention discloses a hip-preserving treatment device, such as Figures 1 to 4As shown in the figure. The hip-preserving treatment device of the present invention includes a cathode decomposition chamber 1 and an anode support nail 2 for penetrating the hip fracture. An accommodation cavity is provided inside the anode support nail 2, and a first opening is provided on the surface of the anode support nail 2, and the first opening communicates with the accommodation cavity. A medicine storage cavity 3 is provided inside the cathode decomposition chamber 1, and medicine is provided inside the medicine storage cavity 3. A second opening communicating with the medicine storage cavity 3 is provided on the cathode decomposition chamber 1. An overflow hole 4 communicating with the accommodation cavity is further provided on the anode support nail 2. During the operation, first, the anode support nail 2 is implanted into the human body so that the anode support nail 2 penetrates the fracture at the hip joint. Then, the solid medicine is put into the medicine storage cavity 3 through the second opening. Subsequently, the cathode decomposition chamber 1 containing the medicine is put into the accommodation cavity through the first opening. Due to the influence of the human body temperature, the solid medicine melts into a liquid state, and the medicine contacts the anode support nail 2 as an electrolyte through the second opening. At this time, since both the cathode decomposition chamber 1 and the anode support nail 2 are in contact with the liquid medicine, the medicine, the cathode decomposition chamber 1, and the anode support nail 2 cooperate with each other to form a discharge structure, and the discharge structure discharges externally using the principle of a primary battery. Therefore, since the anode support nail 2 has been implanted at the hip joint of the human body, the current discharged by the discharge structure can generate an electrical stimulation to the tissues 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 assist in the functional recovery and injury repair of the hip joint. During the discharge process of the discharge structure, the cathode decomposition chamber 1 gradually decomposes, and the medicine flows to the outer periphery of the anode support nail 2 through the overflow hole 4, that is, the medicine flows to the outside of the anode support nail 2 through the overflow hole 4, so that the medicine can flow into the tissues at the hip joint, improve the blood circulation of the tissues at the hip joint, and promote the regeneration of bone cells. The hip-preserving treatment device of the present invention has a simple structure. It not only realizes the fixation of the fracture at the hip joint, but also realizes the drug supply and current stimulation to the tissues at the hip joint, and there is no need to set up infusion tubes and wires outside the body, reducing the risk of infection caused by the infusion tubes.

[0024] In the hip-preserving treatment device of the present invention, there are various implementation manners for many technical features such as the specific shape of the anode support nail 2 and the position of the overflow hole 4. In the following, among many technical features such as the specific shape of the anode support nail 2, one implementation manner is selected for each technical feature for detailed description, and the embodiment where this implementation manner is located is called this embodiment. Other implementation manners of many features such as the specific shape of the anode support nail 2 are called other embodiments, and for other embodiments, a brief description is given below.

[0025] In this embodiment, as Figure 1 and Figure 2As shown, the cathode decomposition chamber 1 is made of chemically active metallic magnesium, and the anode support pin 2 is made of titanium alloy. Titanium alloy has good biocompatibility with human tissues and will not cause an immune response. At the same time, due to the high chemical activity of magnesium, when the drug used as the electrolyte contacts the cathode decomposition chamber 1 and the anode support pin 2 respectively, an immediate rapid redox reaction occurs. As the redox reaction progresses, fine cracks gradually appear on the surface of the cathode decomposition chamber 1 and continue to extend and expand. Until the end of the whole reaction, the cathode decomposition chamber 1 is completely dissolved. The drug stored in the cathode decomposition chamber 1 will diffuse into the hip joint through the overflow hole 4 to treat the diseased part of the hip joint. Part of the metallic magnesium will also flow into the hip joint along with the drug. As one of the essential elements of the human body, metallic magnesium is harmless to the human body. At the same time, the discharge structure generates an electric stimulation of about 2.8V to promote the growth and healing of nerves and tissues at the hip joint. By defining the materials of the cathode decomposition chamber 1 and the anode support pin 2, the present invention effectively discharges the tissues at the hip joint and is harmless to the human body during the decomposition of the cathode decomposition chamber 1. In other embodiments, the cathode decomposition chamber 1 can also be made of metallic zinc with relatively strong activity.

[0026] In this embodiment, as Figure 1 and Figure 5As shown, on the side wall of the anode support pin 2, a compression-resistant area and a tensile-resistant area are symmetrically arranged along the axis of the anode support pin 2. A compression-resistant part 5 is provided in the compression-resistant area, and a tensile-resistant part 6 is provided in the tensile-resistant area. Both the compression-resistant part 5 and the tensile-resistant part 6 are in an eight-shaped configuration. The eight-shaped opening of the compression-resistant part 5 faces the head of the anode support pin 2, and the eight-shaped opening of the tensile-resistant part 6 faces the tail of the anode support pin 2. When the anode support pin 2 is implanted at the hip joint, the tensile-resistant part 6 is arranged towards the human head side, and the compression-resistant part 5 is arranged towards the human foot side. The compression-resistant part 5 and the tensile-resistant part 6 are provided because after the anode support pin 2 is implanted at the hip joint, when a person stands or walks, tensile stress and compressive stress will be generated at the hip joint bones. Specifically at the hip joint, when a person stands or walks, the hip joint bears the weight of the body and the reaction force from the ground. These forces will cause the hip joint bones to bend and deform, resulting in tensile stress on the outer side of the hip joint bones and compressive stress on the inner side of the hip joint bones. Both the tensile stress and the compressive stress may cause the anode support pin 2 to loosen or break. Therefore, the compression-resistant part 5 is set to relieve the compressive stress, thereby enhancing the compression resistance of the anode support pin 2. The tensile-resistant part 6 is set to relieve the tensile stress, thereby enhancing the tensile resistance of the anode support pin 2. The arc shape of the eight-shaped configuration in the compression-resistant part 5 and the tensile-resistant part 6 can effectively relieve the corresponding stress, and since the acting directions of the tensile stress and the compressive stress are opposite, the eight-shaped openings of the compression-resistant part 5 and the tensile-resistant part 6 face in opposite directions. Through the setting of the compression-resistant part 5 and the tensile-resistant part 6, the compression resistance and tensile resistance of the anode support pin 2 are enhanced in the present invention. In other embodiments, the shapes of the compression-resistant part 5 and the tensile-resistant part 6 can also adopt other shapes. For example, both the compression-resistant part 5 and the tensile-resistant part 6 can be set as semi-circular arcs, and the semi-circular arc openings of the compression-resistant part 5 and the tensile-resistant part 6 face in opposite directions.

[0027] In this embodiment, as Figure 1 and Figure 5 shown, both the compression-resistant part 5 and the tensile-resistant part 6 are in an eight-shaped hole configuration, and both the compression-resistant part 5 and the tensile-resistant part 6 are connected to the accommodation cavity. Therefore, the drug stored in the cathode decomposition chamber 1 will also diffuse into the hip joint through the compression-resistant part 5 and the tensile-resistant part 6. At the same time, when the anode support pin 2 is implanted into the human body, the fixed constraint area and the vicinity of the load application point of the anode support pin 2 are often stress concentration areas. Therefore, through the setting of the compression-resistant part 5 with a curvature and the tensile-resistant part 6 with a curvature, the force transmission path can be effectively changed, enabling the force to be more evenly distributed to different parts of the anode support pin 2, avoiding excessive local stress on the anode support pin 2 and thus preventing breakage. In other embodiments, the compression-resistant part 5 and the tensile-resistant part 6 can also be arranged 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 from the overflow hole 4.

[0028] In this embodiment, although both the compressive part 5 and the tensile part 6 are provided with octagonal holes to increase the drug outflow channels, the support strength of the anode support nail 2 is reduced. Therefore, as Figure 1 and Figure 2 shown, the hip-preserving treatment device of the present invention further includes a support part. The purpose of setting the support part is to support the anode support nail 2 to prevent the anode support nail 2 from being excessively deformed. A receiving cavity for receiving the support part is provided on the side wall of the anode support nail 2 of the present invention. The receiving cavity is communicated with the accommodating cavity, and the support part is located between the side wall of the anode support nail 2 and the cathode decomposition chamber 1. The support part has a first state and a second state. When the support part is in the first state, in the length direction of the anode support nail 2, the support part is linear. When the support part is in the second state, in the length direction of the anode support nail 2, the support part is arc-shaped, and the arc-shaped opening of the support part faces the cathode decomposition chamber 1. Generally, first, the anode support nail 2 is implanted into the human body, then the support part in the first state is placed into the receiving cavity, and then the cathode decomposition chamber 1 is placed into the accommodating cavity, so that the support part is located between the side wall of the anode support nail 2 and the cathode decomposition chamber 1. Finally, an external force is used to drive the support part to deform from the first state to the second state, that is, in the length direction of the anode support nail 2, the linear support part is changed into an arc-shaped support part by using an external force. In some cases, it is not necessary to use an external force to change the support part from the first state to the second state. For example, when the support part is made of shape memory alloy, the support part can sense the human body temperature, so that the temperature of the support part changes and the support part deforms. Through the setting of the support part in the present invention, and the support part can be changed from a linear shape to an arc shape in the length direction of the anode support nail 2, it is convenient for the installation of the cathode decomposition chamber 1 and effectively enhances the support strength of the anode support nail 2. In other embodiments, on the premise that the compressive part 5 in the shape of an octagonal hole and the tensile part 6 in the shape of an octagonal hole are provided on the anode support nail 2, the support part may not be provided. However, in order to improve the support strength of the anode support nail 2, it is necessary to increase the microstructure in the accommodating cavity. For example, a number of lattice structures are provided in the accommodating cavity. At this time, the anode support nail 2 needs to be made by 3D printing. However, at present, the support effect and the convenience of use of the 3D-printed anode support nail 2 are not as good as the cooperation of the anode support nail 2 and the support part.

[0029] In this embodiment, as Figures 6 to 8As shown, the support part is a mesh tube 7, and the mesh tube 7 is sleeved outside the cathode decomposition chamber 1. The mesh tube 7 is composed of several grids. The grid structure inside the mesh tube 7 is designed according to the tensile stress and compressive stress received by the anode support pin 2. The grids near the compression part 5 are relatively dense, while the grids near the tensile part 6 are relatively sparse. After the mesh tube 7 changes to the second state, the length of the mesh tube 7 in the radial direction increases, that is, the mesh tube 7 expands. The expanded mesh tube 7 plays a supporting role for the anode support pin 2 to prevent the anode support pin 2 from deforming excessively. At the same time, the material of the mesh tube 7 is a metal material and can conduct electricity. Due to the gravity effect, the drug will flow downward during drug release, resulting in uneven drug release. The mesh tube 7 not only has the function of supporting the anode support pin 2, but also has a mesh structure. When an electric current is generated by electrolysis in the cathode decomposition chamber 1, an electric current will also pass through the mesh tube 7, and these electric currents will attract the anions in the drug, so that the drug is evenly released to any area in the axial direction of the anode support pin 2. In addition, after the mesh tube 7 changes to the second state, that is, after the mesh tube 7 expands, the anode support pin 2 is slightly deformed. And because the grids in the mesh tube 7 are not evenly arranged, when the mesh tube 7 expands, the radial cross-section of the anode support pin 2 changes from a circle to an ellipse, which can enhance the anti-rotation effect of the anode support pin 2. At the same time, although the anode support pin 2 is slightly deformed after the mesh tube 7 expands, since the deformation amplitude of the anode support pin 2 is small, it does not affect the removal of the anode support pin 2 from the human body. In the present invention, by setting the support part as the mesh tube 7, it is convenient for the installation of the support part and the cathode decomposition chamber 1; and by adopting a non-uniform grid design for the mesh tube 7, it is convenient to improve the compressive performance and tensile performance of the anode support pin 2; and by making the mesh tube 7 of metal, it is convenient for better drug release. In other embodiments, the support part can also be a metal strip.

[0030] In this embodiment, as Figure 3 and Figure 4 shown, an anti-rotation drill 17 is provided at the nail head of the anode support pin 2, and the overflow hole 4 is provided at the nail head of the anode support pin 2. Specifically, the overflow hole 4 is provided on the anti-rotation drill 17. The setting of the anti-rotation drill 17 prevents the anode support pin 2 from rotating randomly during the process of installing the anode support pin 2 into the human body, so that the compression part 5 and the tensile part 6 cannot be located at the set positions. That is, it prevents the tensile part 6 from deviating from the direction towards the human head. In the present invention, by setting the anti-rotation drill 17, the random rotation of the anode support pin 2 is prevented. In other embodiments, threads can also be provided on the outer wall of the entire anode support pin 2. When drilling a hole at the hip joint, tapping is carried out at the same time, and then the anode support pin 2 is screwed into the hip joint.

[0031] In this embodiment, as Figures 1 to 4As shown, the overflow hole 4 is arranged away from the second opening, that is, the overflow hole 4 is not directly communicated with the second opening, so as to prevent the situation that the liquid medicine flows out of the overflow hole 4 prematurely before the discharge structure is fully discharged. In other embodiments, the overflow hole 4 may also be directly communicated with the second opening. However, in this case, a degradable film for closing the second opening needs to be arranged on the cathode decomposition chamber 1, and a spike for piercing the degradable film is arranged on the inner wall of the accommodating cavity. The spike is also made of titanium alloy. When the cathode decomposition chamber 1 enters the accommodating cavity, the spike pierces the degradable film. At this time, since the degradable film is not decomposed, the degradable film blocks the second opening and the overflow hole 4. With the continuous discharge reaction of the spike, the medicine, and the cathode decomposition chamber 1, the degradable film is continuously decomposed, and then the medicine can continuously flow out of the overflow hole 4.

[0032] In this embodiment, as Figures 7 to 10 shown, the hip-preserving treatment device of the present invention includes a support. The support includes a support body 8, a first fixing hole arranged on the support body 8, a second fixing hole arranged on the support body 8, and a locking screw 9 passing through the first fixing hole. The anode support nail 2 passes through the second fixing hole. When the hip-preserving treatment device of the present invention connects the mutually split first bone 18 and second bone 19, first, holes are drilled in the first bone 18 and the second bone 19, then the support body 8 is fixed at the corresponding installation position of the first bone 18, and then the locking screw 9 is passed through the first fixing hole and fixed on the first bone 18. Finally, the anode support nail 2 is passed through the second fixing hole so that the anode support nail 2 connects the first bone 18 and the second bone 19 at the same time. Through the arrangement of the support, the anode support nail 2 can stably connect the mutually split first bone 18 and second bone 19 together. In other embodiments, when fixing holes for accommodating the anode support nail 2 are drilled in the first bone 18 and the second bone 19, and threads are tapped on the fixing holes, and threads matching the fixing holes are arranged on the outer wall of the anode support nail 2, the support in this embodiment may not be provided.

[0033] In this embodiment, as 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. The first fixing hole is provided on the screw fixing plate 8b, and the second fixing hole is provided on the support pin fixing tube 8a. The outer wall of the anode support pin 2 is provided with a stepped surface, and a blocking portion 15 cooperating with the stepped surface is provided on the second fixing hole. The blocking portion 15 is provided at the second end of the support pin fixing tube 8a. During the use of the hip-preserving treatment device of the present invention, the anode support pin 2 is inserted into the second fixing hole from the first end of the support pin fixing tube 8a. As the anode support pin 2 continuously moves towards the second end of the support pin fixing tube 8a, finally the blocking portion 15 contacts the stepped surface, and the blocking portion 15 restricts the movement of the anode support pin 2 in the direction towards the second end of the support pin fixing tube 8a. By providing a stepped surface on the outer wall of the anode support pin 2 and a 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 limiting block may also be provided on the anode support pin 2, and a limiting groove cooperating with the limiting block is provided on the support pin fixing tube 8a. The limiting groove extends to the first end of the support pin fixing tube 8a.

[0034] Based on the hip-preserving treatment device of the present embodiment described above, the hip-preserving treatment device of the present invention can be divided into two types. One is a non-drug-supplementable hip-preserving treatment device. In this type of hip-preserving treatment device, the drug in the cathode decomposition chamber 1 cannot be supplemented. The following takes Embodiment 1 as an example to describe this type of hip-preserving treatment device in detail. The other is a drug-supplementable hip-preserving treatment device. In this type of hip-preserving treatment device, the cathode decomposition chamber 1 can be continuously supplemented into the anode support pin 2. The following takes Embodiment 2 as an example to describe this type of hip-preserving treatment device in detail.

[0035] Embodiment 1: As Figure 1 、 Figure 2 、 Figure 5 and Figure 12As shown, the hip-preserving treatment device in Embodiment 1 includes a first sealing member. The first sealing member includes a first abutting portion 10 and a first sealing portion 11 connected to the first abutting portion 10. After the cathode decomposition chamber 1 is placed into the accommodating cavity with the second opening facing the direction of the nail head of the anode support nail 2, and the mesh tube 7 is installed into the accommodating cavity and expands, the first sealing member is then installed. In Embodiment 1, the first sealing portion 11 is provided with a first external thread, and the first end of the support nail fixing tube 8a is provided with a first internal thread 20 that mates with the first external thread. During the installation process of the first sealing member, the first abutting portion 10 is inserted into the accommodating cavity, and the first sealing member is driven to move towards the direction of the nail head of the anode support nail 2. The first external thread and the first internal thread 20 continuously engage until the first abutting portion 10 abuts against the cathode decomposition chamber 1, making the cathode decomposition chamber 1 fixed relative to the anode support nail 2. At this time, due to the abutment of the first abutting portion 10, the drug is in full contact with the anode support nail 2, and the discharge structure can discharge fully.

It not only realizes the fixation of the crack at the hip joint, but also realizes the drug supply and current stimulation to the tissues at the hip joint, without the need to set up infusion tubes and wires outside the body. By defining the materials of the cathode decomposition chamber 1 and the anode support nail 2, it can effectively discharge to the tissues at the hip joint, and is harmless to the human body during the decomposition process of the cathode decomposition chamber 1. Through the settings of the compression-resistant part 5 and the tension-resistant part 6, the compression-resistant ability and tension-resistant ability of the anode support nail 2 are enhanced. By setting the compression-resistant part 5 and the tension-resistant part 6 to be in the shape of an eight-shaped hole, while the drug can flow out from the compression-resistant part 5 and the tension-resistant part 6, the stress concentration of the anode support nail 2 is reduced. Through the setting of the support part, the support strength of the anode support nail 2 is effectively enhanced. By setting the support part as the mesh tube 7, it is convenient for the installation of the support part and the cathode decomposition chamber 1; by adopting a non-uniform grid design for the mesh tube 7, it is convenient to improve the compression-resistant performance and tension-resistant performance of the anode support nail 2; by making the mesh tube 7 of metal, it is convenient for better release of the drug. Through the setting of the anti-rotation drill 17, it prevents the anode support nail 2 from rotating randomly. By setting the overflow hole 4 away from the second opening, it prevents the liquid drug from flowing out of the overflow hole 4 prematurely. Through the setting of the support, the anode support nail 2 can stably connect the mutually split first bone 18 and the second bone 19 together. Through the setting of the blocking part 15 and the stepped surface, it prevents the anode support nail 2 from deviating from the predetermined surgical position. Through the settings of the first abutting part 10 and the first sealing part 11, while preventing external bacteria from entering the inside of the anode support nail 2, it enables the discharge structure to discharge fully. Through the settings of the medicine adding tube 12 and the second sealing member, it is convenient for the discharge structure to discharge fully, convenient for the replenishment of the drug, and prevents bacteria from entering the human body.
