[0040] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Figure 1a It is a schematic diagram of the structure of the bracket provided by the present invention;

[0042] Figure 1b It is a structural schematic diagram of the guide plate positioning slider provided by the present invention;

[0043] Figure 1c It is a structural schematic diagram of a force line rod slider fixing block provided by the present invention;

[0044] Figure 1d , which is a schematic structural diagram of the force line rod slider provided by the present invention;

[0045] Figure 1e It is a structural schematic diagram of the detachable base provided by the present invention.

[0046] Figure 2 1 is a schematic diagram of a detection system for a positioning tool for knee replacement provided by the present invention. The detection system 10 for a positioning tool for knee replacement may include: a bracket 101, a guide plate positioning slider 102, a force line rod slider fixing block 103 and a force line rod slider 104;

[0047] The guide plate positioning slider 102 is slidably disposed on a first side of the first end of the bracket 101, and is used to cooperate with the positioning tool 20 for connection, and the first side is a side close to the positioning tool 20;

[0048] The force line rod slider fixing block 103 is arranged on the second side of the first end of the bracket 101, and the second side is the opposite side of the first side. The force line rod slider fixing block 103 is slidably connected to the force line rod slider 104 below; when the positioning tool 20 is installed to the knee joint prosthesis model and the guide plate positioning slider 102 is cooperatively connected to the positioning tool 20, the force line rod slider 104 is used to determine the force line position corresponding to the knee joint prosthesis model to determine the qualification of the positioning tool 20.

[0049] Among them, the positioning tool 20 is generated by three-dimensional (3D) printing. After the positioning tool 20 is fitted onto the knee prosthesis model, the bone implant screw can fix the positioning tool 20 on the knee prosthesis model. Then, the positioning tool 20 can effectively and accurately determine the position of the metal osteotome.

[0050] It can be understood that the sliding path of the guide plate positioning slider 102 on the first side of the first end of the bracket 101 is parallel to the sliding path of the force line rod slider 104 below the force line rod slider fixing block 103, so that the force line rod slider 104 can accurately determine the force line position corresponding to the knee joint prosthesis model on the guide plate positioning slider 102.

[0051] In the embodiment of the present invention, the detection system 10 is relatively simplified, and is used to solve the problem that the existing detection method for the positioning tool 20 (for example: osteotomy positioning) is implemented by a traditional TKA corresponding holding instrument. However, due to the large number of surgical instruments, heavy weight, and complex assembly methods, it is impossible to accurately detect the qualification defects of the osteotomy positioning. The qualification of the positioning tool 20 can be accurately determined based on the accurate force line position obtained.

[0052] In addition, in the prior art, the traditional TKA only determines the deviation of the stress line of the knee prosthesis model based on the knee joint X-ray or computer tomography (CT) before the operation, which affects the angle judgment and may cause a certain degree of error in the TKA operation process. However, the detection system 10 involved in the embodiment of the present invention can flexibly move the force line rod slider 104, and then accurately determine the force line position corresponding to the knee prosthesis model; then, the user can perform the next osteotomy operation, and the detection system 10 will accurately implant the positioning tool 20 into the tibia corresponding to the knee prosthesis model, thereby effectively shortening the operation time and reducing the operation error.

[0053] Optionally, the thickness of the guide plate positioning slider 102 may be a preset thickness threshold.

[0054] Exemplarily, it is assumed that the preset thickness threshold is 1.6 millimeters (mm), that is, the thickness of the guide plate positioning slider 102 is 1.6 mm.

[0055] In some embodiments, the positioning tool 20 is an osteotomy guide plate 201, which is provided with an osteotomy groove 2012; an opening is provided on the first side of the first end of the bracket 101, and the guide plate positioning slider 102 is slidably arranged in the opening, and the guide plate positioning slider 102 is inserted into the osteotomy groove 2012 for cooperating and connecting with the osteotomy guide plate 201.

[0056] The osteotomy guide plate 201 is generated by 3D printing.

[0057] The guide plate positioning slider 102 can slide in the opening of the first end of the bracket 101 corresponding to the first side, and can be accurately inserted into the osteotomy groove 2012, so as to effectively and reliably fix the osteotomy guide plate 201.

[0058] Optionally, when the osteotomy guide 201 is a tibial guide, the tibial guide may include a tibial guide body, a tibial osteotomy groove is provided on the first side of the tibial guide body, the tibial osteotomy groove passes through one end of the tibial guide body, and a sickle blade is inserted into the tibial osteotomy groove; a fitting groove is provided on the second side of the tibial guide body; a force line rod fixing plate parallel to the tibial osteotomy groove is provided at one end of the tibial guide body, and a force line rod jack is provided at the end of the force line rod fixing plate away from the tibial guide body, which is configured to be able to insert the force line rod.

[0059] For example, Figure 3a , which is a schematic diagram of the structure of the osteotomy guide plate provided by the present invention. Figure 3aIn the embodiment, two osteotomy grooves 2012 are provided on the osteotomy guide plate 201, and the notch thickness of the osteotomy grooves 2012 is 1.6 mm. In this way, when the notch thickness of the osteotomy grooves 2012 is the same as the slider thickness of the guide plate positioning slider 102, the guide plate positioning slider 102 can be effectively and reliably inserted into the osteotomy grooves 2012 to be matched and connected with the osteotomy guide plate 201, that is, to fix the osteotomy guide plate 201. At this time, the osteotomy grooves 2012 and the force line rod slider 104 are perpendicular; when the notch thickness of the osteotomy grooves 2012 is different from the slider thickness of the guide plate positioning slider 102, the guide plate positioning slider 102 cannot be effectively and reliably inserted into the osteotomy grooves 2012, resulting in the detection system 10 accurately determining that the osteotomy guide plate 201 is unqualified.

[0060] For example, Figure 3b As shown in FIG. 1 , it is a schematic diagram of a scene in which the osteotomy guide plate provided by the present invention is placed on a detection system; Figure 3c The figure is a schematic diagram of a scene of the osteotomy guide plate provided by the present invention on a detection system. Figure 3b The scene diagram shown is similar to Figure 3c The scene diagrams are shown from different angles.

[0061] For example, Figure 3d , which is a schematic diagram of the sliding scene of the osteotomy guide plate and the force line rod slider provided by the present invention. Figure 3d In the embodiment, when the detection system 10 is located on a horizontal plane, the guide plate positioning slider 102 can slide horizontally on the first side of the first end of the bracket 101 based on the horizontal plane, and the force line rod slider 104 can slide horizontally below the force line rod slider fixing block 103 based on the horizontal plane. The sliding path of the guide plate positioning slider 102 is parallel to the sliding path of the force line rod slider 104, so as to ensure that the force line rod slider 104 can effectively determine the force line position corresponding to the knee joint prosthesis model.

[0062] Optionally, the number of the guide plate positioning sliders 102 is at least two.

[0063] The number of guide plate positioning sliders 102 can be adjusted based on the number of notches of the osteotomy groove 2012 .

[0064] When there are two guide plate positioning sliders 102, the detection system 10 can slide and adjust the positions of the two guide plate positioning sliders 102 according to the different sizes of osteotomy guide plates 201, so as to effectively and reliably fix the osteotomy guide plates 201, thereby enabling the detection system 10 to detect the qualification of osteotomy guide plates 201 of different sizes.

[0065] In some embodiments, the guide plate positioning slider 102 may include a sliding end and a mating end, the sliding end is slidably disposed in the opening of the first side corresponding to the first end of the bracket 101, and the mating end is matingly connected to the positioning tool 20; an indicator line is provided on the upper end surface of the mating end, and the indicator line is used to indicate the end position of the mating end inserted into the positioning tool 20.

[0066] The sliding end of the guide plate positioning slider 102 is slidably disposed in the opening of the first side corresponding to the first end of the bracket 101. Based on the indicator line on the upper end surface of the matching end, it can be ensured that the matching end and the positioning tool 20 can be effectively matched and connected.

[0067] In some embodiments, a connecting structure is provided at the lower end of the force line rod slider 104; the connecting structure is used to connect to the extension rod.

[0068] Optionally, a threaded connection or a plug-in connection is provided inside the lower end of the force line rod slider 104 for adding an extension rod.

[0069] Since the force line lengths of the knee joint prosthesis model corresponding to the tibia are different, the force line rod slider 104 can determine whether an extension rod needs to be added to the lower end of the force line rod slider 104 based on the force line length. When the force line length is greater than the rod length of the force line rod slider 104, the detection system 10 outputs a prompt message, which is used to prompt the user to add an extension rod to the lower end connection structure of the force line rod slider 104, so that the force line length is less than or equal to the rod length after the extension rod is added, thereby ensuring that the force line rod slider 104 can effectively determine the force line position corresponding to the knee joint prosthesis model.

[0070] For example, Figure 3e , which is a schematic diagram of the structure of the force line rod slider provided by the present invention. Figure 3e In the embodiment, a threaded structure is provided inside the lower end of the force line rod slider 104, and the threaded structure can be a threaded hole.

[0071] In some embodiments, it also includes: a detachable base 105, the detachable base 105 is connected to the second end of the bracket 101, and is used to support the bracket 101, and the second end is the opposite end of the first end.

[0072] The detachable base 105 supports the bracket 101, which can ensure that the bracket 101 does not shake and is continuously in a fixed state.

[0073] Optionally, the force line rod slider 104 is T-shaped.

[0074] The force line rod slider 104 is T-shaped and can slide horizontally below the force line rod slider fixing block 103 to effectively determine the force line position corresponding to the knee joint prosthesis model.

[0075] For example, Figure 3f, which is a schematic diagram of the position of the force line rod slider provided by the present invention compared to the knee joint prosthesis model. Figure 3f In the process of determining the force line position of the knee prosthesis model, the detection system 10 can move the force line rod slider 104 to a preset position of the knee prosthesis model, which can be 1 / 3 inside the tibial tuberosity, that is, on the coronal plane, inward from the center of the tibial tuberosity.

[0076] The following is a description of the detection method of the positioning tool for knee replacement provided by the present invention. The detection method of the positioning tool for knee replacement described below and the detection system of the positioning tool for knee replacement described above can be referenced to each other.

[0077] like Figure 4 FIG. 1 is a flow chart of a detection method for a positioning tool for knee replacement provided by the present invention, which may include:

[0078] 401. When the guide plate positioning slider is in a state of being cooperatively connected with the positioning tool, obtain a first matching degree between the guide plate positioning slider and the positioning tool.

[0079] In some embodiments, the positioning tool is an osteotomy guide plate, which is provided with an osteotomy groove; the detection device obtains the first matching degree between the guide plate positioning slider and the positioning tool, which may include: the detection device obtains the slider thickness corresponding to the guide plate positioning slider and the slot thickness corresponding to the osteotomy groove; the detection device determines the first matching degree between the guide plate positioning slider and the osteotomy guide plate based on the thickness difference between the slider thickness and the slot thickness.

[0080] The thickness difference is an absolute value of the difference, that is, a positive value.

[0081] Different thickness differences correspond to different matching degrees: the smaller the thickness difference, the closer the guide plate positioning slider fits the osteotomy groove, and at this time, the matching degree between the guide plate positioning slider and the osteotomy guide is higher; the larger the thickness difference, the less close the guide plate positioning slider fits the osteotomy groove, and at this time, the matching degree between the guide plate positioning slider and the osteotomy guide is lower.

[0082] 402. When the positioning tool is installed on the knee joint prosthesis model, determine the force line position corresponding to the knee joint prosthesis model.

[0083] When the positioning tool is installed on the knee prosthesis model, the detection device can move the force line rod sliding block at the lower end of the force line rod slider fixing block to the preset position of the knee prosthesis model. The force line rod sliding block is flexible and can accurately determine the force line position corresponding to the knee prosthesis model.

[0084] 403. Obtain a second matching degree between the force line position and the force line rod slider.

[0085] In some embodiments, the method may also include: a detection device obtains the force line length corresponding to the knee prosthesis model and the rod length corresponding to the force line rod slider; when the force line length is greater than the rod length, the detection device outputs a prompt message, and the prompt message is used to prompt the user to add an extension rod to the lower end of the force line rod slider.

[0086] In the case where the rod length of the force line rod slider is greater than the force line length corresponding to the knee joint prosthesis model, it can be effectively ensured that the force line rod slider can accurately determine the force line length. However, when the force line length is greater than the rod length, it means that the force line rod slider cannot accurately determine the force line length. At this time, the detection device can output a prompt message, and then the user can add an extension rod to the lower end of the force line rod slider according to the prompt message to ensure that the new rod length corresponding to the force line rod slider must be greater than the force line length, so that the force line rod slider after adding the extension rod can accurately determine the force line length.

[0087] Optionally, the timing of the detection device obtaining the first matching degree between the guide plate positioning slider and the positioning tool and obtaining the second matching degree between the force line position and the force line rod slider is not limited.

[0088] 404. Determine the eligibility of the positioning tool according to the first matching degree and the second matching degree.

[0089] In some embodiments, the detection device determines the qualification of the positioning tool based on the first matching degree and the second matching degree, which may include: the detection device determines that the positioning tool is qualified when the first matching degree is greater than a first preset threshold and the second matching degree is greater than a second preset threshold; the detection device determines that the positioning tool is unqualified when the first matching degree is less than or equal to the first preset threshold, and / or the second matching degree is less than or equal to the second preset threshold.

[0090] Among them, the first preset threshold and the second preset threshold can be the same or different. The first preset threshold and the second preset threshold can be set by the detection device before leaving the factory or can be user-defined, which is not specifically limited here.

[0091] Exemplarily, it is assumed that the first preset threshold is 99% and the second preset threshold is 99%.

[0092] When the first matching degree of the detection device is greater than the first preset threshold and the second matching degree is greater than the second preset threshold, it means that the first matching degree and the second matching degree are both high, and at this time, the positioning tool can be determined to be qualified; when the first matching degree of the detection device is less than or equal to the first preset threshold, and / or the second matching degree is less than or equal to the second preset threshold, it means that the first matching degree and / or the second matching degree is low, and at this time, the positioning tool can be determined to be unqualified.

[0093] In an embodiment of the present invention, a first matching degree between the guide plate positioning slider and the positioning tool is obtained; the force line position corresponding to the knee joint prosthesis model is determined; a second matching degree between the force line position and the force line rod slider is obtained; and the qualification of the positioning tool is determined based on the first matching degree and the second matching degree. In this method, the detection device can flexibly move the force line slider to accurately determine the force line position corresponding to the knee joint prosthesis model, and effectively and accurately determine whether the positioning is qualified based on the first matching degree between the guide plate positioning slider and the positioning tool and the second matching degree between the force line position and the force line rod slider.

[0094] like Figure 5 FIG. 1 is a schematic diagram of a detection device for a positioning tool for knee replacement surgery provided by the present invention, which may include:

[0095] An acquisition module 501 is used to acquire a first matching degree between the guide plate positioning slider and the positioning tool when the guide plate positioning slider and the positioning tool are in a state of being matched and connected;

[0096] A determination module 502 is used to determine the force line position corresponding to the knee joint prosthesis model when the positioning tool is installed on the knee joint prosthesis model;

[0097] An acquisition module 501 is used to acquire a second matching degree between the force line position and the force line rod slider;

[0098] The determination module 502 is used to determine the eligibility of the positioning tool according to the first matching degree and the second matching degree.

[0099] Optionally, the determination module 502 is specifically used to determine that the positioning tool is qualified when the first matching degree is greater than a first preset threshold and the second matching degree is greater than a second preset threshold; and to determine that the positioning tool is unqualified when the first matching degree is less than or equal to the first preset threshold and / or the second matching degree is less than or equal to the second preset threshold.

[0100] Optionally, the positioning tool is an osteotomy guide plate, and the osteotomy guide plate is provided with an osteotomy groove;

[0101] An acquisition module 501 is specifically used to acquire a slider thickness corresponding to the guide plate positioning slider and a slot thickness corresponding to the osteotomy slot;

[0102] The determination module 502 is specifically configured to determine a first matching degree between the guide plate positioning slider and the osteotomy guide plate according to a thickness difference between the slider thickness and the slot thickness.

[0103] Optionally, a connection structure is provided at the lower end of the force line rod slider, and the acquisition module 501 is further used to acquire the force line length corresponding to the knee joint prosthesis model and the rod length corresponding to the force line rod slider;

[0104] The output module 503 is used to output a prompt message when the length of the force line is greater than the length of the rod, and the prompt message is used to prompt the user to connect an extension rod at the connection structure.

[0105] like Figure 6 , is a schematic diagram of the structure of an electronic device provided by the present invention, the electronic device may include: a processor 610, a communication interface 620, a memory 630 and a communication bus 640, wherein the processor 610, the communication interface 620 and the memory 630 communicate with each other through the communication bus 640.
