Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to a novel laser emission positioning osteotomy device. Background Art

[0002] Osteotomy is one of the important means to treat a variety of bone diseases and deformity correction. With the continuous development of medical technology and the increasing requirements of patients for surgical effects and postoperative recovery quality, the demand for accuracy, safety and efficiency of osteotomy has become increasingly prominent. Traditional osteotomy mainly relies on the doctor's clinical experience and the use of some conventional measuring tools and positioning instruments to determine the osteotomy position and angle, but these methods have certain limitations in practical applications.

[0003] The distal femoral condyle morphology and size of different patients vary from individual to individual, making it difficult to accurately fix the positioning block at the distal center of the femoral condyle for each patient. This can easily lead to certain deviations, which affects the accuracy of subsequent osteotomy positioning and results in a lack of real-time monitoring and fine-tuning mechanisms. However, once a slight deviation from the center occurs during the fixation process, the doctor can only rely on his or her experience and visual judgment to find the exact position. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a novel laser emission positioning osteotomy device to solve the problem that if a slight deviation from the center occurs during the fixation process, it is impossible to detect and adjust it in time, resulting in the inability to accurately find the position only by relying on the doctor's experience and naked eye judgment.

[0013] The present invention provides a novel laser emission positioning osteotomy device, which has the following beneficial effects: 1. The present invention fixes the distal femoral condyle intercondylar positioning block to the distal center of the femoral condyle, and the anterior superior iliac ridge positioning pins of the hip positioning device are respectively located at the anterior superior iliac ridges on both sides. The component positioning rods are respectively perpendicular to the femoral head in the sagittal plane and perpendicular to the front edge of the greater trochanter apex in the coronal plane to achieve the effect of rapid fixation, and the combined design of the rotating sleeve and the rotating pin can achieve left and right, up and down movements, achieving the effect of 360° rotation positioning requirements.

[0015] 3.

[0018] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only 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.

[0019] Example

[0020] Please refer to the attached Figure 1 -Attached Figure 4 and attached Fig. 9 The embodiment of the present invention provides a novel laser emission positioning osteotomy device, including a rotating sleeve 3, the outer wall of the rotating sleeve 3 is slidably connected with a main bracket 10, a conversion slot 9 is arranged inside the main bracket 10, the outer wall of the conversion slot 9 is slidably connected with a femoral osteotomy adapter module 5, the inside of the femoral osteotomy adapter module 5 is rotatably connected with an adapter module disassembly cover 6, a sagittal limit groove 7 is provided inside the adapter module disassembly cover 6, a conversion module fixing hole 8 is provided inside the adapter module disassembly cover 6, the outer wall of the conversion slot 9 is slidably connected to the lower surface of the adapter module disassembly cover 6, a rotating pin 4 is provided inside the main bracket 10, an osteotomy hip positioning component 15 is arranged on the left outer wall of the femoral osteotomy adapter module 5, a laser emitter body 11 is arranged on the inner wall of the main bracket 10, both sides of the outer walls of the main bracket 10 are rotatably connected with a laser emitter auxiliary bracket 12, and the outer wall of the laser emitter body 11 is slidably connected to the inside of the laser emitter auxiliary bracket 12.

[0021] Specifically, the sliding connection structure formed by the rotating sleeve 3 and the main bracket 10 plays an effect of flexibly adjusting the position during use. The rotating sleeve 3 serves as a basic support, and its outer wall is slidably connected to the main bracket 10, so that the main bracket 10 can move freely on the rotating sleeve 3 in the left and right, up and down directions according to the surgical requirements. This provides flexible and changeable basic conditions for accurately positioning the osteotomy position in the subsequent situation of different patient bone morphologies and osteotomy sites, ensuring that the device can better adapt to various surgical scenarios. The conversion slot 9 set inside the main bracket 10 is used as a connection part with the femoral osteotomy adapter module 5 during use. Through the sliding connection method, the femoral osteotomy adapter module 5 can be steadily and accurately adjusted on its outer wall to adapt to the osteotomy operation in different areas of the femur; on the other hand, the cooperation of the conversion slot 9 and other related components and the connection with the adapter module disassembly cover 6 lay the foundation for the switching and positioning of different functional modules of the entire device, ensuring the orderly realization of various functions of the device during the osteotomy operation. The rotation of the femoral osteotomy adapter module 5 and the adapter module disassembly cover 6 facilitates the adjustment before and after the operation. The inspection, maintenance and replacement of the internal components of the device greatly improve the maintainability of the device. The sagittal limit groove 7 in the adapter module disassembly cover 6 can accurately limit the position to ensure that the sagittal displacement of the component is limited, provide an accurate reference for laser emission positioning, and avoid osteotomy positioning errors; and the conversion module fixing hole 8 can be connected to the components by screws and the like to ensure that the device structure can still maintain an accurate relative position when disturbed by external forces during surgery. The osteotomy hip positioning component 15 on the left outer wall of the femoral osteotomy adapter module 5 can accurately determine the key elements such as the osteotomy line and the amount of osteotomy in hip osteotomy surgery based on the anatomical characteristics of the human hip and in coordination with other components to improve the accuracy and success rate of the surgery. The laser emitter body 11 is the key to realizing the precise positioning of the osteotomy function. The osteotomy position and direction are determined by emitting a laser beam and cooperating with other positioning components. The laser emitter auxiliary bracket 12 rotatably connected to the outer walls on both sides of the main bracket 10 can flexibly adjust the laser emission angle, and the sliding connection between the laser emitter body 11 and the laser emitter auxiliary bracket 12 can further finely adjust the emission position. The combination of the two can meet the diverse needs for laser emission angles and positions during surgery.

[0022] Please refer to the attached Figure 3 , Attachment Figure 6 -Attached Figure 8 A positioning assembly is provided on the left side of the laser transmitter body 11, and the positioning assembly includes a main support rod 16, and the outer wall of the main support rod 16 is slidably connected with an anterior superior iliac ridge positioning needle 17; the anterior superior iliac ridge positioning needle 17 is used for anterior superior iliac ridge positioning, and the main support rod 16 is used to support the connection between the positioning; the outer wall of the main support rod 16 is slidably connected with a fixed lock A18, and the inner wall of the fixed lock A18 is provided with a connecting rod 19; the outer wall of the connecting rod 19 is provided with a fixed lock B20, and the inner wall of the fixed lock B20 is provided with a positioning rod 21.

[0023] Specifically, the outer wall of the main support rod 16 is slidably connected with an anterior superior iliac spine positioning pin 17. During use, the anterior superior iliac spine positioning pin 17 plays the role of accurately locating the anterior superior iliac spine. Through it, the position of the anterior superior iliac spine of the human body can be accurately determined, providing a key reference point for the positioning of the entire osteotomy operation in the hip area. The main support rod 16 plays the role of connecting and supporting. As a supporting structure, it connects various related positioning components together to ensure the integrity and stability of the entire positioning assembly, so that various positioning components can work together under its support to serve accurate osteotomy positioning. The outer wall of the main support rod 16 is slidably connected with a fixed lock buckle A18. The fixed lock buckle A18 plays the role of locking and adjusting the position during use. It can be locked after sliding to a suitable position on the main support rod 16, thereby fixing the position of the components connected thereto, ensuring that the relevant components will not be displaced unnecessarily during the operation, and ensuring the accuracy of positioning. The inner wall of the fixed lock buckle A18 is provided with a connecting rod 19. The connecting rod 19 plays the role of connecting and transmitting. It will fix the fixed lock buckle A18 8 is connected with subsequent fixed lock buckle B20 and positioning rod 21 and other components, so that the force transmission and position association can be achieved between the various components, and the coherence and coordination of the internal structure of the entire positioning component are guaranteed. The outer wall of the connecting rod 19 is provided with a fixed lock buckle B20, and the fixed lock buckle B20 also has the effect of locking and adjusting the position. Similar to the fixed lock buckle A18, it can slide and lock on the connecting rod 19, and further fine-tune the position of the components connected to it. It works together with the fixed lock buckle A18 to enhance the accuracy of the position adjustment of the entire positioning component. The inner wall of the fixed lock buckle B20 is provided with a positioning rod 21, and the positioning rod 21 has the effect of precise positioning during use. During the osteotomy operation, it can cooperate with other positioning components according to the characteristics of the human anatomical structure to accurately determine the position of a specific part. For example, in hip osteotomy, it may work with other components to determine the position of key parts such as the femoral head and greater trochanter, providing an accurate reference for determining key elements such as the osteotomy line and osteotomy amount, which helps to improve the accuracy and success rate of osteotomy.

[0024] Please refer to the attached Figure 1 -Attached Figure 3The inner wall of the main bracket 10 is provided with an auxiliary bracket slot 14, and the laser emitter auxiliary bracket 12 also includes a mounting bracket 121 and an adjustment bracket 122. The mounting bracket 121 and the adjustment bracket 122 are connected by a hinge 123. The mounting bracket 121 is provided with a mounting block 124, which can be quickly disassembled and assembled. The laser emitter body 11 is fixed by the mounting block 124, and the adjustment bracket 122 is rotatably connected to the outer walls on both sides of the main bracket 10. A bracket locking block 13 is provided on the rotating shaft. The bracket locking block 13 is used to lock the relative position of the adjustment bracket 122 and the main bracket 10; the lower surface of the rotating sleeve 3 is fixedly connected with a positioning block fixing hole 2, and the lower surface of the positioning block fixing hole 2 is fixedly connected with a distal femoral condylar positioning block 1, and the upper surface of the positioning block fixing hole 2 is slidably connected to the lower surface of the main bracket 10.

[0025] Specifically, the lower surface of the rotating sleeve 3 is fixedly connected with a positioning block fixing hole 2, and the positioning block fixing hole 2 plays a role of connection and positioning. On the one hand, it serves as a fixed connection part with the rotating sleeve 3 to ensure the stability of its own structure; on the other hand, it provides an accurate installation position for the subsequent connection of the distal femoral intercondylar positioning block 1, so that the distal femoral intercondylar positioning block 1 can be accurately installed on its lower surface, laying the foundation for the positioning operation of the entire device at the distal femur. The lower surface of the positioning block fixing hole 2 is fixedly connected with the distal femoral intercondylar positioning block 1, and the distal femoral intercondylar positioning block 1 plays a key initial positioning role in use. Before the osteotomy operation begins, it is accurately fixed in the distal femoral intercondylar position as the first positioning of the entire device in the distal femoral area. The reference point provides a starting coordinate basis for subsequent more precise positioning operations through laser emission and other methods, ensuring that the entire osteotomy positioning process can be carried out in an orderly manner based on the accurate initial position. The upper surface of the positioning block fixing hole 2 is slidably connected to the lower surface of the main bracket 10. This sliding connection method enables a relatively flexible connection relationship to be established between the main bracket 10 and the rotating sleeve 3 and its auxiliary structures. During the operation, according to different osteotomy requirements and differences in patient bone morphology, the laser transmitter body 11 is fixed by installing the card block 124, and can be quickly disassembled and assembled. A bracket locking block 13 is provided on the rotating shaft. The relative position of the bracket 122 and the main bracket 10 is adjusted by the bracket locking block 13, which has the effect of rapid positioning during use.

[0026] Working principle: When the device is needed, the sliding connection structure formed by the rotating sleeve 3 and the main bracket 10 can flexibly adjust the position during use. The rotating sleeve 3 serves as a basic support, and its outer wall is slidably connected to the main bracket 10, so that the main bracket 10 can be freely moved in left and right, up and down directions on the rotating sleeve 3 according to surgical requirements. This provides flexible and changeable basic conditions for accurately positioning the osteotomy position in the subsequent case of different patient bone morphologies and osteotomy sites, ensuring that the device can better adapt to various surgical scenarios. The conversion slot 9 arranged inside the main bracket 10 is used as a connection part with the femoral osteotomy adapter module 5. Through the sliding connection method, the femoral osteotomy adapter module 5 can be smoothly and accurately adjusted on its outer wall to adapt to osteotomy operations in different areas of the femur. On the other hand, the cooperation of the conversion slot 9 and other related components and the connection with the adapter module disassembly cover 6 lay the foundation for the switching and positioning of different functional modules of the entire device, ensuring the orderly realization of various functions of the device during the osteotomy operation. The rotation of the femoral osteotomy adapter module 5 and the adapter module disassembly cover 6 facilitates the inspection, maintenance and replacement of the internal components of the device before and after the operation, greatly improving the maintainability of the device. The laser emitter body 11 is the key to realizing the precise positioning of the osteotomy function. The osteotomy position and direction are determined by emitting a laser beam and cooperating with other positioning components. The laser emitter auxiliary bracket 12 rotatably connected to the outer walls on both sides of the main bracket 10 can flexibly adjust the laser emission angle, and the sliding connection between the laser emitter body 11 and the laser emitter auxiliary bracket 12 further finely adjusts the emission position. The sagittal limit groove 7 in the adapter module disassembly cover 6 can accurately limit the position, ensure that the sagittal displacement of the component is limited, provide an accurate reference for laser emission positioning, and avoid the effect of osteotomy positioning error. The anterior superior iliac spine positioning needle 17 is slidably connected to the outer wall of the main support rod 16. During use, the anterior superior iliac spine positioning needle 17 plays the effect of accurately locating the anterior superior iliac spine. Through it, the position of the anterior superior iliac spine of the human body can be accurately determined, providing a key reference point for the positioning of the entire osteotomy operation in the hip area. The main support rod 16 plays the effect of connecting and supporting. As a supporting structure, it connects various related positioning components together to ensure the integrity and stability of the entire positioning assembly, so that each positioning component can work together under its support to serve accurate osteotomy positioning. The outer wall of the main support rod 16 is slidably connected with a fixed lock buckle A18. The fixed lock buckle A18 plays the effect of locking and adjusting the position in use. It can be locked after sliding to a suitable position on the main support rod 16, thereby fixing the position of the components connected to it, ensuring that the relevant components will not have unnecessary displacement during the operation, and ensuring the accuracy of positioning; The inner wall of the fixed lock buckle A18 is provided with a connecting rod 19, which plays a role of connection and transmission. It connects the fixed lock buckle A18 with the subsequent fixed lock buckle B20 and the positioning rod 21 and other components, so that the transmission of force and the relationship of position can be achieved between the various components, ensuring the coherence and coordination of the internal structure of the entire positioning component. The outer wall of the connecting rod 19 is provided with a fixed lock buckle B20, which also plays a role of locking and adjusting the position. Similar to the fixed lock buckle A18, it can slide and lock on the connecting rod 19, further fine-tune the position of the components connected thereto, and work together with the fixed lock buckle A18 to enhance the accuracy of the position adjustment of the entire positioning component. The inner wall of the fixed lock buckle B20 is provided with a positioning rod 21, which plays a role of precise positioning during use. The lower surface of the rotating sleeve 3 is fixedly connected with a positioning block fixing hole 2, and the positioning block fixing hole 2 plays a role of connection and positioning.

The lower surface of the positioning block fixing hole 2 is fixedly connected with the distal femoral intercondylar positioning block 1, and the distal femoral intercondylar positioning block 1 plays a key initial positioning role in use. Before the osteotomy operation begins, it is accurately fixed at the distal femoral intercondylar position as the first positioning reference point of the entire device in the distal femoral area, providing a starting coordinate basis for subsequent more precise positioning operations through laser emission and the like, ensuring that the entire osteotomy positioning process can be carried out in an orderly manner based on the accurate initial position.
