Description

Technical Field

[0001] This invention relates to the field of bone drilling training simulation equipment, and more particularly to an operational simulation device for training orthopedic bone drilling skills. Background Technology

[0002] In orthopedic clinical practice, minimally invasive bone drilling surgery has become the mainstream procedure for fracture reduction and joint replacement due to its advantages of minimal trauma and rapid recovery. This type of surgery demands extremely high precision in incision size and drilling angle, requiring medical staff to develop muscle memory and standardized operating techniques through extensive specialized training. However, current orthopedic bone drilling skills training equipment generally lacks specificity: existing equipment focuses primarily on routine bone drilling operations and does not design specialized training structures for the characteristics of minimally invasive surgery. It only uses training modes with a single, fixed-size incision or no incision restrictions, failing to simulate the core operational requirements of "small incision, precise angle" in minimally invasive surgery, making it difficult for trainees to master the techniques. To master the unique incision control and depth management techniques of minimally invasive surgery, and to address the issues raised by existing equipment that uses only a single material to simulate tissue, trainees cannot perceive the tactile differences when penetrating muscle layers and contacting bone during minimally invasive surgery, making it difficult to develop feedback and cognition consistent with clinical minimally invasive procedures. Furthermore, existing equipment cannot adjust incision parameters according to the trainee's skill progression needs, failing to achieve graded training from basic incision control to complex angle bone drilling. This results in a severe disconnect between training and clinical minimally invasive surgical scenarios, making it difficult to meet the needs of medical staff to improve their minimally invasive bone drilling skills. Therefore, we propose an operational simulation device for orthopedic bone drilling skill training to solve the aforementioned problems. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the prior art by proposing an operational simulation device for training orthopedic bone drilling skills.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an operational simulation device for training orthopedic bone drilling skills, comprising a housing, modules arranged on both sides of the upper part of the housing, a mold cavity arranged in the middle of the side of the modules that are close to each other, a rotating seat arranged at the front and rear of the modules, an electric push rod installed in the middle of the rotating seat, a bone body clamped between the telescopic ends of the electric push rod, the bone body being disposed inside the mold cavity, a driven gear installed at the opposite end of the rotating seat, a connecting seat installed in the middle of the opposite end of the modules, mounting brackets installed on both sides of the middle of the opposite end of the modules, and a... The device includes a scissor frame, with connecting blocks rotatably connected to each end of the scissor frame. A threaded rod is threaded through and threadedly connected to the center of each connecting block on the side of the scissor frame away from the module. A limiting rod is slidably connected to the center of each connecting block on the side of the scissor frame closer to the module. A slide is provided on the upper side between the modules, with an inner cavity inside the slide. A film is provided in the center of each inner cavity, with an opening in the center of each film. A guide groove is provided on the edge of each film, with a slider slidably connected inside each guide groove. An electric push rod is rotatably connected to the end of each slider away from the film, and a rotating seat is rotatably connected to the end of each electric push rod away from the slider.

[0005] Preferably, a base is rotatably connected to the bottom of the box, and hydraulic rods are rotatably connected to both sides of the top of the base. The ends of the hydraulic rods away from the base are rotatably connected to the bottom of the box, and control buttons are provided on the front side of one side of the box.

[0006] Preferably, electric slide rails are installed on both sides of the top of the box, and end caps are installed on the sliding parts of the electric slide rails. A reserved opening is provided in the middle of the end caps that are close to each other, and a sliding groove is provided on the top of the end caps.

[0007] Preferably, each of the adjacent ends of the rotating base is equipped with a sealing seat, which is used to cooperate with the end of the module to achieve sealing, and the middle of each sealing seat is penetrated by an electric push rod.

[0008] Preferably, the end of the connecting seat away from the module is fixedly connected to a connecting pipe, and the end of the connecting pipe away from the connecting seat is fixedly connected to a bottom compartment, and the bottom compartment is installed at the bottom of the box body.

[0009] Preferably, each threaded rod end is equipped with a stepper motor, and the stepper motors are all installed inside the housing.

[0010] Preferably, a motor is installed in the middle of each of the rotating seats, and the drive shaft of each motor is connected to the two ends of the electric push rod. Both the rotating seat and the two electric push rods are located inside the slide.

[0011] Preferably, conductive strips are installed on both the front and rear parts of the carriage, and the end of the conductive strip away from the carriage passes through the top of the end cover. A power receiving roller is provided on the end of the conductive strip away from the carriage. The power receiving roller is installed in the middle of the front and rear sides of the housing through a fixing frame. The power receiving roller is connected to an external power source and is used to supply power to the internal equipment of the carriage through the conductive strip.

[0012] Preferably, each driven gear is meshed with a driving gear at its bottom, and a servo motor is mounted on one side of the central shaft of each driving gear.

[0013] Preferably, limit strips are installed on the bottom of both sides of the slide, and the bottom of the limit strips are slidably connected to the inside of the slide groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Addressing the issue that minimally invasive bone drilling surgery requires extremely high precision in incision and angle control, and that existing equipment lacks specialized training support, this device utilizes a specialized adjustment structure consisting of a film with an opening in the inner cavity of the slide, a guide groove, a slider, an electric push rod, and a rotating seat. This allows for precise simulation of the "small incision, high precision" operation scenario of minimally invasive surgery, filling the gap in existing equipment's inability to conduct specialized training for minimally invasive bone drilling and significantly improving the alignment between training and clinical practice.

[0016] To address the issue that existing equipment can only simulate tissue layers in a single way and cannot reproduce the combined structure of muscles and bones, this device uses an infusion system consisting of a mold cavity inside the module, a connecting seat, a connecting pipe, and a bottom chamber. After the bone body is placed inside the mold cavity and clamped and fixed by an electric push rod, the gel is injected into the mold cavity through the connecting pipe and the connecting seat via a pump in the bottom chamber. After the gel solidifies, it forms a simulated muscle layer. Combined with the bone structure, it creates a "muscle and bone" two-layer structure that closely resembles the human body, allowing trainees to perceive the differences in the feel of real tissues. This solves the problem of distorted operation feedback caused by traditional equipment that only uses a single material to simulate tissues.

[0017] To address the issues of unstable bone fixation and inconvenient bone replacement affecting training continuity, the device incorporates rotating seats at the front and rear of the module. An electric push rod is installed in the center of the rotating seat, allowing trainees to quickly clamp and release the bone by controlling the extension and retraction of the electric push rod, eliminating the need for complex fixation structures. Simultaneously, the rotating seat and module rotate in tandem, utilizing a transmission structure of driven gears, driving gears, and a servo motor. Activating the servo motor drives the driving gear to rotate, thus synchronizing the rotating seat, electric push rod, and bone. This ensures bone stability during training and enables multi-angle bone adjustment. Furthermore, the rewinding or release of the conductive strip by the electric roller moves the slide along the end cover groove, allowing trainees to practice bone drilling operations at different positions and angles, meeting the needs of bone drilling training in various orientations.

[0018] To address the issues of difficulty in controlling the size and angle of the opening and insufficient training targeting in minimally invasive bone drilling training, the device incorporates a film with a central opening within the inner cavity of the upper side slide of the module. A slider, an electric push rod, and a rotating seat, all slidably connected within the guide groove on the edge of the film, form an adjustment mechanism. Activating the electric push rod can move the edge of the film by pulling the slider, thus deforming the opening. The motor on the rotating seat drives the electric push rod to deflect, changing the tension position of the slider within the guide groove. This allows for precise adjustment of the opening size, shape, and tilt angle, simulating the opening requirements of minimally invasive surgery in different locations. This overcomes the shortcomings of traditional devices that cannot adapt to diverse training scenarios due to their fixed opening design.

[0019] To address the issue of varying skill levels among trainees and the inability to progressively adjust training difficulty, the device adapts to different skill levels through structural adjustments. Beginners can use the initial film for basic training. Once proficient, they can adjust the opening size using an electric push rod and change the opening shape using a motor to increase the difficulty. For advanced training, a servo motor can be used to rotate the bone, and an electric roller can be used to move the slide to achieve dynamic target bone drilling. This forms a complete training gradient from basic to advanced levels, solving the problem that traditional equipment designs are too simplistic to meet the training needs of different stages.

[0027] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0028] like Figures 1-6 The illustrated simulation device for training orthopedic bone drilling skills includes a housing 133. Modules 126 are arranged on both sides of the upper part of the housing 133. A mold cavity 125 is arranged in the middle of the side of the module 126 that is close to each other. Rotary seats 120 are arranged at the front and rear of the module 126. An electric push rod 109 is installed in the middle of the rotary seat 120. A bone body 127 is held between the telescopic ends of the electric push rod 109. The bone body 127 is located inside the mold cavity 125. A driven gear 118 is installed at the far end of the rotary seat 120. A drive gear 119 is meshed at the bottom of the driven gear 118. A servo motor is installed on one side of the shaft of the drive gear 119. A sealing seat 124 is installed at the close end of the rotary seat 120. The sealing seat 124 is used to cooperate with the end of the module 126 to achieve sealing. The middle of the sealing seat 124 is penetrated by the electric push rod 109.

[0029] Furthermore, in practical implementation, the bone structure 127 required for training can be placed between the front and rear electric push rods 109. Then, the electric push rods 109 can be activated, and their electric extension clamps the bone structure 127. The pump inside the base chamber 112 can be activated, allowing the quick-setting gel to be introduced into the mold cavity 125 via the connecting pipe 123 and connecting seat 116. This gel acts as a muscle layer. Once the gel solidifies, the stepper motor controls module 126. The device moves to both sides, exposing the colloid and bone 127, making it convenient for people to perform bone drilling training. During bone drilling, people can start the servo motor, which drives the drive gear 119 to rotate. The drive gear 119 drives the driven gear 118 that meshes with it to rotate. The driven gear 118 drives the rotating seat 120, the electric push rod 109, and the muscle and bone 127 in the middle to rotate synchronously, thus facilitating people to perform comprehensive bone drilling training and making it beneficial for practical use.

[0030] In this configuration, a connecting seat 116 is installed at the middle of the end of module 126 that is far away from module 126. A connecting pipe 123 is fixedly connected to the end of the connecting seat 116 that is far away from module 126. A bottom compartment 112 is fixedly connected to the end of the connecting pipe 123 that is far away from the connecting seat 116. The bottom compartment 112 is installed at the bottom of the box 133. A stepper motor is installed at the end of the threaded rod 113. The stepper motor is installed inside the box 133. Mounting brackets 121 are installed on both sides of the middle of the end of module 126 that is far away from module 126. Scissor frames 110 are provided on both sides of the upper part of the box 133. A connecting block 111 is rotatably connected to the end of the scissor frame 110. A threaded rod 113 is threaded through and threadedly connected to the middle of the connecting block 111 on the side of the scissor frame 110 that is close to module 126. A limiting rod 122 is slidably connected to the limiting rod 122 on the side of the scissor frame 110 that is close to module 126.

[0031] Furthermore, in specific implementation, the operation of the stepper motor can drive the threaded rods 113 on both sides to rotate. The threaded rods 113 can drive the connecting blocks 111 to move in opposite directions, thereby driving the scissor frame 110 to retract or expand. By controlling the expansion of the scissor frame 110, the limiting rods 122 can be used to drive the modules 126 on both sides to separate, thereby exposing the inner structure. The approach of the modules 126 can cooperate with the sealing seat 124 to seal the mold cavity 125.

[0032] The bottom of the housing 133 is rotatably connected to a base 101. Both sides of the top of the base 101 are rotatably connected to hydraulic rods 102. The ends of the hydraulic rods 102 away from the base 101 are rotatably connected to the bottom of the housing 133. A control button 103 is provided on the front side of one side of the housing 133. Electric slide rails are installed on both sides of the top of the housing 133. End caps 134 are installed on the sliding parts of the electric slide rails. A reserved opening is provided in the middle of the end caps 134 that are close to each other. A sliding groove 104 is provided on the top of the end caps 134.

[0033] Furthermore, in practical implementation, people can train their bone drilling skills through the bone drilling training box. In specific use, people can first loosen the electric roller 115 on one side by controlling button 103, so that people can lift the slide 105 and make the limiting strip 108 disengage from the slide groove 104. Then, the end cover 134 can be slid open to both sides by the operation of the electric slide rail, so that the inside of the box 133 can be exposed. After the bone body 127 is replaced, people can close the end cover 134 again by the electric slide rail and put the slide 105 back into the slide groove 104. Then, the electric roller 115 is used to roll up and tighten the conductive strip 107. Then, the stepper motor is started to control the scissor frame 110 to retract, which can drive the modules 126 on both sides to close.

[0034] The slide 105 is equipped with conductive strips 107 at both the front and rear. The end of the conductive strip 107 away from the slide 105 passes through the top of the end cover 134. The end of the conductive strip 107 away from the slide 105 is provided with a receiving roller 115. The receiving roller 115 is installed in the middle of the front and rear sides of the housing 133 through the fixing frame 114. The receiving roller 115 is connected to an external power source and is used to power the internal equipment of the slide 105 through the conductive strip 107. Limiting strips 108 are installed on the bottom of both sides of the slide 105. The bottom of the limiting strips 108 is slidably connected to the inside of the slide groove 104.

[0035] Furthermore, in specific implementation and training, people can start the electric roller 115 to rotate by controlling button 103. By controlling the rotation of one side of the electric roller 115, the overall position of the slide 105 can be moved, thereby assisting people in performing low-invasive bone drilling training in different positions.

[0036] Among them, a slide 105 is provided on the upper side between modules 126, and an inner cavity 130 is provided inside the slide 105. A film 106 is provided in the middle of the inner cavity 130. The film 106 is made of high elastic medical silicone material. An opening 117 is opened in the middle of the film 106. A guide groove 132 is opened on the edge of the film 106. A slider 131 is slidably connected to the inner side of the guide groove 132. An electric push rod 129 is rotatably connected to the end of the slider 131 away from the film 106. A rotating seat 128 is rotatably connected to the end of the electric push rod 129 away from the slider 131. A motor is installed in the middle of the rotating seat 128. The drive shaft of the motor is connected to the end of the electric push rod 129. The rotating seat 128 and the electric push rod 129 are both located inside the slide 105.

[0037] Furthermore, in practical implementation, people can perform bone drilling training on the lower simulated muscle and bone body 127 through the opening 117 on the film 106. The opening 117 can limit the size of the opening and the angle of the bone drilling surgery, thus facilitating low-invasive bone drilling surgery training and benefiting practical use. Furthermore, people can activate the electric push rod 129 inside the slide 105. The operation of the electric push rod 129 can use the slider 131 to pull the edge of the film 106 to move, thereby achieving stretching deformation of the film 106, which can further drive the movement of the film 106. The opening 117 of the part deforms, thereby enabling adjustment of the size and shape of the opening 117. This allows for adjustments based on different training progresses, facilitating gradual bone drilling training. The motor inside the slide 105 drives the electric push rod 129 to deflect. The deflection of the electric push rod 129 causes the slider 131 at its end to move along the guide groove 132, thereby changing the position of the stretching point of the film 106. This further adjusts the shape of the stretched opening 117, which is beneficial for improving or adjusting the difficulty of the minimally invasive bone drilling surgery.

[0038] Working principle:

[0039] In practical use, the bone drilling training box allows users to train their bone drilling skills. Specifically, users first loosen the electric roller 115 on one side using control button 103, allowing the slide 105 to be lifted, causing the limiting strip 108 to disengage from the slide groove 104. Then, the electric slide rails allow the end cap 134 to slide open to both sides, exposing the interior of the box 133. At this point, the stepper motor drives the threaded rods 113 on both sides to rotate. These threaded rods 113 drive the connecting blocks 111 to move in opposite directions, thus causing the scissor frame 110 to retract or expand. By controlling the expansion of the scissor frame 110, the limiting rod 122 can separate the modules 126 on both sides, allowing the box to... With the inner structure exposed, the bone 127 required for training can be placed between the front and rear electric push rods 109. The electric push rods 109 can then be activated, extending to clamp the bone 127. After the bone 127 is replaced, the end cap 134 can be closed again via the electric slide rail, and the slide 105 can be repositioned into the slide groove 104. The conductive strip 107 is then wound and tightened via the electric roller 115. The stepper motor then controls the scissor frame 110 to retract, causing the modules 126 on both sides to close. The proximity of the modules 126, combined with the sealing seat 124, seals the mold cavity 125. The pump inside the bottom chamber 112 can then be activated, using a continuous... The connector 123 and connecting seat 116 input quick-gel material into the mold cavity 125. The gel acts as a muscle layer. After the gel solidifies, the stepper motor controls the module 126 to move to both sides, thereby exposing the gel and bone 127 for bone drilling training. At this time, people can perform bone drilling training on the lower simulated muscle and bone 127 through the opening 117 on the film 106. The opening 117 can limit the size of the opening and the angle of the bone drilling surgery, thus facilitating low-invasive bone drilling training and improving practical use. During specific training, people can start the electric roller 115 to rotate by controlling the button 103. By controlling the rotation of one side of the electric roller 115, the slide 105 can be adjusted. The overall positional movement assists in low-invasive bone drilling training at different locations. Simultaneously, the user can activate the servo motor, which drives the drive gear 119 to rotate. The drive gear 119 then drives the meshing driven gear 118, which in turn drives the rotating seat 120, the electric push rod 109, and the central muscle and bone body 127 to rotate synchronously. This facilitates comprehensive bone drilling training and is beneficial for practical use. Furthermore, the user can activate the electric push rod 129 inside the slide 105. The operation of the electric push rod 129 allows the slider 131 to pull the edge of the film 106, thereby achieving stretching and deformation of the film 106.This allows for further deformation of the opening 117 in the middle of the film 106, enabling adjustment of the size and shape of the opening 117. This allows for adjustments based on different training progress, facilitating gradual bone drilling training. Simultaneously, the motor within the slide 105 drives the electric push rod 129 to deflect. This deflection causes the slider 131 at the end of the electric push rod 129 to move along the guide groove 132, thereby changing the position of the stretching point on the film 106. This further adjusts the shape of the stretched opening 117, improving or adjusting the difficulty of the minimally invasive bone drilling surgery.
