Technical Field

[0001] This invention relates to the field of bone cutting instruments, specifically an electric bone cutting instrument for femoral head surgery. Background Technology

[0002] Currently, if a patient needs knee replacement or to have a prosthesis implanted in the knee joint, the femoral condyle must be reshaped and processed to achieve a specific shape for installation with the desired prosthesis. In existing techniques, the entire knee joint is typically exposed during surgery, and the distal, anterior, posterior, anterior oblique, and posterior oblique surfaces of the femoral condyle are individually cut to create a specific shape for prosthesis placement.

[0003] However, in the current technology, most of the bone cutting instruments on the market require manual hand operation during femoral head surgery. This is physically demanding and can easily damage blood vessels or nerves on both sides during bone cutting. In addition, the rapid rotation of the blade can easily cause bone fragments to scatter everywhere, leading to troublesome post-operative care. Therefore, there is a need to propose an electric bone cutting instrument for femoral head surgery. Summary of the Invention

[0004] The purpose of this invention is to provide an electric osteotomy device for femoral head surgery, in order to solve the problems mentioned in the background art. In the process of femoral head surgery, most osteotomy devices on the market require manual hand-held operation, which is physically demanding and can easily damage blood vessels or nerves on both sides during osteotomy.

A wire mesh injection end hole is connected to the bottom of the micro injection pump.

[0007] Preferably, a high-definition endoscope is installed on the bottom side of the electric osteotomy, and a temperature rise correction component is installed on the side of the electric osteotomy.

[0008] Preferably, the temperature rise correction component includes an argon gas injection control tank, the bottom of which is connected to an injection connection control valve pipe.

[0009] Preferably, the argon injection control canister is mounted on the side surface of the electric bone cutter via a side frame, and a rotating transverse groove frame is fastened to the bottom side of the injection communication control valve tube via a connecting column. A rotation angle control motor is mounted on the side of the rotating transverse groove frame.

[0010] Preferably, the inside of the rotating transverse slot frame is rotatably connected to a short adjusting transverse rail, and the side of the short adjusting transverse rail is connected to an adjusting guide post via a side motor.

[0011] Preferably, the external of the adjusting guide post is slidably connected to an argon gas injection end, and the top end of the argon gas injection end is connected to an injection communication control valve via a pipeline.

[0012] Preferably, gantry frames are symmetrically installed at both ends of the lateral displacement adjusting rail, and longitudinal displacement rails are installed at the bottom of each gantry frame, with a mounting plate installed at the bottom of each longitudinal displacement rail.

[0013] Preferably, two sets of placement slots are symmetrically installed on the surface of the mounting plate, and a side connection control board is installed inside the two sets of placement slots. An adhesive contact sheet is installed on the side of the side connection control board.

[0014] Preferably, there is an installation space at the connection between the adhesive contact sheet and the side connection control plate, and an expansion compression airbag is installed inside the installation space. Multiple array-type neural detection sensors are embedded inside the adhesive contact sheet.

[0015] Preferably, a micro control air pump is installed on the side of each of the two sets of placement slots, and a microprocessor controller is installed on the side of the micro control air pump. The side of the micro control air pump is connected to the inlet and outlet air core of the expansion and compression airbag through a thin tube.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In this invention, with the cooperation of the protective adjustment components, the vertical short adjustment rail drives the reinforcing sliding rod and the connecting bearing rod through the internal screw, causing the reinforcing sliding rod and the connecting bearing rod to slide along the screw, thereby driving the connecting rectangular plate, the rectangular side frame and the connected structure to achieve initial vertical positioning. Then, the adjustment rotating seat at the bottom of the connecting bearing rod is finely adjusted by a high-precision angle adjustment motor, which can drive the rectangular side frame and the structure it supports to finely adjust their angles. Then, the three sets of short displacement adjustment rails are started synchronously, and under the control of the preset program, the three sets of short displacement adjustment rails drive the first micro electromagnetic guide rod, the rotating shaft joint, the second micro electromagnetic guide rod, and the... The micro-injection pump and the wire mesh injection end hole are adjusted by changing their positions, and in conjunction with the first micro-electromagnetic guide rod, the rotating shaft, and the second micro-electromagnetic guide rod, the micro-injection pump and the wire mesh injection end hole held by the clamping device can form multi-dimensional point calibration in three sets of short displacement adjustment rails. This allows the micro-injection pump to be activated before or during the bone cutting process, so that chitosan can form a thin film structure through the wire mesh injection end hole to wrap the nerve or bone. This allows the bone fragments generated during the bone cutting operation to a certain extent to be adhered and gathered, making them easier to collect later, and preventing the bone fragments from affecting the operation, thus reducing surgical risks and complications.

[0018] 2. In this invention, with the assistance of a temperature rise correction component, when the electric osteotome is working and heat is detected at the cutting site, and the temperature exceeds a preset safety threshold, the argon gas injection control tank is activated. This allows argon gas to be delivered from the argon gas injection control tank to the argon gas injection end, thereby reducing the temperature of the electric osteotome and the cutting site and protecting surrounding tissues from heat damage. When the temperature changes, the rotation angle control motor is activated, causing the rotation angle control motor to drive the short adjusting horizontal rail inside the rotating transverse slot frame to rotate, thereby causing the argon gas injection end to adjust its angle. This allows the adjusting guide post to convert the power of the side motor into the lateral movement of the short adjusting horizontal rail, facilitating the adjustment of the argon gas injection end along the trajectory of the short adjusting horizontal rail inside the adjusting guide post, forming a left-right displacement adjustment of the argon gas injection end. Combined with the above angle adjustment, precise position adjustment is achieved. After the above angle and left-right displacement adjustment, the argon gas injection end reaches the preset injection position. The injection connection control valve can control the argon gas flow rate based on the temperature monitoring data from the external temperature sensor to adjust the temperature of the electric osteotome and the cutting site, effectively reducing the damage to surrounding tissues caused by temperature rise.

[0019] 3. In this invention, by combining an adhesive contact patch, an expansion and compression airbag, and a micro-control air pump, the micro-control air pump, connected to the air inlet and outlet core of the expansion and compression airbag via a thin tube, controls the inflation and deflation of the airbag. This allows the microprocessor controller to receive data from multiple array-type nerve detection sensors, analyze nerve activity patterns, and control the operation of the micro-control air pump accordingly. This adjusts the pressure of the expansion and compression airbag, allowing air to enter and causing the adhesive contact patch to contact the patient's skin. The internally integrated array-type nerve detection sensors can collect nerve signals in real time, monitor changes in nerve signals, and provide real-time feedback to the overall control system, forming a precise osteotomy path. This ensures that the electric osteotomy device effectively avoids damage to peripheral blood vessels and nerves. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

A sliding laser position detection seat 2 is slidably connected to the bottom end of the lateral displacement adjusting rail 1. A high-precision medical multi-axis robotic arm 3 is connected to the bottom end of the sliding laser position detection seat 2.

The reinforcing sliding rod 181 is located at the top of the connecting support rod 182 and fastened to it. An adjusting rotating seat 183 is fastened to the bottom of the connecting support rod 182. A high-precision angle adjustment motor 184 is mounted on the side of the rotating seat 183. The bottom end of the rotating shaft sleeve connected to the output end of the high-precision angle adjustment motor 184 is hinged to a connecting rectangular plate 185. A rectangular side frame 186 is fastened to the bottom of the connecting rectangular plate 185. Three sets of short displacement adjustment rails 187 are installed inside the rectangular side frame 186, forming a triangular mounting structure. A first micro electromagnetic guide rod 188 is slidably connected inside each of the three sets of short displacement adjustment rails 187. A rotating shaft joint 189 is connected to the bottom end of the first micro electromagnetic guide rod 188. A second micro electromagnetic guide rod 1890 is connected to the side end of the rotating shaft joint 189. A clamping component is fastened to the side end of the second micro electromagnetic guide rod 1890. A micro injection pump 1891 is installed inside the clamping component. A wire mesh injection end hole 1892 is connected to the bottom of the micro injection pump 1891.

[0029] according to Figure 3 As shown, a high-definition endoscope 17 is installed on the bottom side of the electric osteocutter 13, and a temperature rise correction component 14 is installed on the side of the electric osteocutter 13. The high-definition endoscope 17 is installed on the bottom side of the electric osteocutter 13 to provide a real-time internal view during the operation. With the help of an external real-time image, the high-definition endoscope 17 follows the electric osteocutter 13 into the surgical end, uses the built-in camera to capture the osteocutter image, and transmits it to an external display, so that medical staff can see a high-definition image of the surgical site in real time.

[0030] according to Figure 4As shown, the temperature rise correction component 14 includes an argon gas injection control tank 140. The bottom end of the argon gas injection control tank 140 is connected to an injection connection control valve pipe 142. The argon gas injection control tank 140 is a container for storing argon gas. When the electric osteocutter 13 is working, if heat is detected at the cutting site and the temperature exceeds a preset safety threshold, the argon gas injection control tank 140 is activated. This allows argon gas to be delivered from the argon gas injection control tank 140 to the argon gas injection end 147, thereby reducing the temperature of the electric osteocutter 13 and the cutting site and protecting the surrounding tissue from thermal damage.

[0031] according to Figure 4 As shown, the argon injection control tank 140 is mounted on the side surface of the electric bone cutter 13 via a side frame. The bottom side of the injection connection control valve pipe 142 is fastened to a rotating transverse groove frame 143 via a connecting column. A rotation angle control motor 144 is mounted on the side of the rotating transverse groove frame 143. When the temperature changes, the rotation angle control motor 144 is activated, causing the rotation angle control motor 144 to drive the short adjusting transverse rail 145 inside the rotating transverse groove frame 143 to rotate, thereby causing the argon injection end 147 to adjust the angle.

[0032] according to Figure 4 As shown, a short adjusting horizontal rail 145 is rotatably connected inside the rotating horizontal slot frame 143. An adjusting guide post 146 is connected to the side of the short adjusting horizontal rail 145 via a side motor. The side motor is installed on the side of the short adjusting horizontal rail 145 and connected to the adjusting guide post 146, so that the adjusting guide post 146 converts the power of the side motor into the lateral movement of the short adjusting horizontal rail 145. This facilitates the adjustment of the argon gas injection end 147 along the trajectory of the short adjusting horizontal rail 145 inside the adjusting guide post 146, forming a left and right displacement adjustment of the argon gas injection end 147. Combined with the above-mentioned angle adjustment, a precise position adjustment is achieved.

[0033] according to Figure 4 As shown, an argon gas injection end 147 is slidably connected to the outside of the adjusting guide post 146. The top end of the argon gas injection end 147 is connected to the injection communication control valve pipe 142 through a pipeline. After the above-mentioned angle and left and right displacement are adjusted, the argon gas injection end 147 reaches the preset injection position. The injection communication control valve pipe 142 can control the flow rate of argon gas to adjust the temperature of the electric bone cutter 13 and the cutting part according to the temperature monitoring data of the external temperature sensor.

[0034] according to Figure 1 and Figure 2As shown, gantry frames 4 are symmetrically installed at the left and right ends of the lateral displacement adjustment rail 1. Longitudinal displacement rails 5 are installed at the bottom of each gantry frame 4. A mounting plate 6 is installed at the bottom of the longitudinal displacement rail 5. With the cooperation of the gantry frame 4 and the longitudinal displacement rail 5, the electric osteocutter 13 can be adjusted again synchronously after adjustment, so that the electric osteocutter 13 can accurately reach the preset surgical position.

[0035] according to Figure 1 and Figure 2 As shown, two sets of placement slots 7 are symmetrically installed on the surface of the mounting plate 6. Side connection control plates 8 are installed inside the two sets of placement slots 7. Adhesive contact sheets 10 are installed on the sides of the side connection control plates 8. The mounting plate 6 serves as a base platform, and the two sets of placement slots 7 symmetrically installed on its surface provide positioning and support for the surgical position required by the patient.

[0036] according to Figure 1 and Figure 2 As shown, there is an installation space at the connection between the adhesive contact patch 10 and the side connection control plate 8. An expansion compression airbag 9 is installed inside the installation space. Multiple array-type nerve detection sensors are embedded inside the adhesive contact patch 10. The side connection control plate 8 is installed inside the placement slot 7 to connect and control the multiple array-type nerve detection sensors to process and transmit data. Then, when the patient places the desired femoral head position on the surface of the adhesive contact patch 10, the expansion compression airbag 9 is inflated, causing the adhesive contact patch 10 to contact the patient's skin. The multiple array-type nerve detection sensors embedded inside can collect nerve signals in real time, monitor changes in nerve signals, and provide real-time feedback to the overall control system (such as a logic controller) to form a precise osteotomy path, so that the electric osteotomy device 13 can effectively avoid damage to peripheral blood vessels and nerves.

[0037] according to Figure 1 and Figure 2 As shown, a micro-control air pump 12 is installed on the side of each of the two sets of placement slots 7. A microprocessor controller 11 is installed on the side of each micro-control air pump 12. The side of the micro-control air pump 12 is connected to the inlet and outlet air core of the expansion and compression airbag 9 through a thin tube. The micro-control air pump 12 is responsible for controlling the inflation and deflation of the expansion and compression airbag 9 through the connection between the micro-control air pump 12 and the inlet and outlet air core of the expansion and compression airbag 9. It also enables the microprocessor controller 11 to receive data from multiple sets of array-type nerve detection sensors, analyze nerve activity patterns, and control the operation of the micro-control air pump 12 accordingly. It adjusts the pressure of the expansion and compression airbag 9 to achieve closed-loop control of nerve signals, thereby further improving the accuracy of nerve position and change detection during bone cutting.

[0038] The wiring diagrams for the sliding laser position detection base 2, the adhesive contact sheet 10, the microprocessor controller 11, the micro control air pump 12, the argon jet control tank 140, the rotation angle control motor 144, the high-precision angle adjustment motor 184, the micro injection pump 1891, and the array-type neural detection sensor in this invention are common knowledge in the field. Their working principles are well-known technologies, and the appropriate models are selected according to actual use. Therefore, the control methods and wiring arrangements for the sliding laser position detection base 2, the adhesive contact sheet 10, the microprocessor controller 11, the micro control air pump 12, the argon jet control tank 140, the rotation angle control motor 144, the high-precision angle adjustment motor 184, the micro injection pump 1891, and the array-type neural detection sensor will not be explained in detail.

[0039] The usage and working principle of this device are as follows: First, when a patient needs to undergo femoral head surgery, the patient's surgical site, such as the knee joint, is positioned so that the bottom of the patient's knee joint is placed on the surface of the adhesive contact sheet 10 inside the two sets of placement slots 7. Then, a micro-controlled air pump 12 is connected to the inlet and outlet air core of the expansion and compression airbag 9 through a thin tube. This micro-controlled air pump 12 is responsible for controlling the inflation and deflation of the expansion and compression airbag 9. The microprocessor controller 11 receives data from multiple sets of array-type nerve detection sensors, analyzes nerve activity patterns, and controls the operation of the micro-controlled air pump 12 accordingly. This adjusts the pressure of the expansion and compression airbag 9, allowing air to enter the expansion and compression airbag 9, which in turn drives the adhesive contact sheet 10 into contact with the patient's skin. The multiple sets of internally fitted array-type nerve detection sensors then work together to achieve the desired effect. The neural detection sensor can collect nerve signals in real time, monitor changes in nerve signals, and provide real-time feedback to the overall control system (such as a logic controller) to form a precise osteotomy path. This allows the electric osteotomy device 13 to effectively avoid damage to peripheral blood vessels and nerves. Then, in conjunction with external real-time imaging and the overall control system, the lateral displacement adjustment rail 1 drives the sliding laser position detection seat 2 and its supporting structure to synchronously adjust left and right displacement. Using the sliding laser position detection seat 2, the position of the patient's incision is calibrated in real time. Based on the position feedback data from the sliding laser position detection seat 2, the high-precision medical multi-axis robotic arm 3, after multi-axis adjustment, drives the electric osteotomy device 13 to the femoral head of the patient's incision for the surgical procedure. During the procedure, a high-definition endoscope 17 is mounted on the side and bottom of an electric osteotomer 13. Based on the operating mode of the electric osteotomer 13, it provides a real-time internal view during the surgery. Combined with an external real-time imaging system, the high-definition endoscope 17 follows the electric osteotomer 13 into the surgical area, capturing the osteotomy image using its built-in camera and transmitting it to an external monitor. This allows medical personnel to see a high-definition image of the surgical site in real time, enabling better treatment of the femoral head. Simultaneously, with the cooperation of the gantry 4 and the longitudinal displacement rail 5, the electric osteotomer 13 can be adjusted again synchronously after adjustment, ensuring precise real-time treatment of the femoral head. Furthermore, before operating on the femoral head, the auxiliary rotating ring 15 and the annular guide rail 16 can drive the anti-corrosion... The protective adjustment component 18 is adjusted. Then, when the protective adjustment component 18 reaches the preset position, the vertical short adjustment rail 180 drives the reinforcing sliding rod 181 and the connecting support rod 182 via an internal screw, causing the reinforcing sliding rod 181 and the connecting support rod 182 to slide along the screw, thus driving the connecting rectangular plate 185, the rectangular frame 186, and the connected structure to achieve initial vertical positioning. Next, the adjustment rotating seat 183 at the bottom of the connecting support rod 182 undergoes fine-tuning of the angle via a high-precision angle adjustment motor 184, which in turn drives the rectangular frame 186 and the structure it supports to make fine-tuning of the angle. Then, the three sets of short displacement adjustment rails 187 are started synchronously, and under the control of a preset program, the three sets of short displacement adjustment rails 187...The first micro electromagnetic guide rod 188, the rotating shaft joint 189, the second micro electromagnetic guide rod 1890, the micro injection pump 1891, and the wire mesh injection end hole 1892 are adjusted and varied. These components, along with the first micro electromagnetic guide rod 188, the rotating shaft joint 189, and the second micro electromagnetic guide rod 1890, allow for finer position adjustments. This enables the micro injection pump 1891 and the wire mesh injection end hole 1892, held by the clamping device, to achieve multi-dimensional point calibration within the three sets of short displacement adjustment rails 187. This, in turn, allows for precise adjustments before or during the bone-cutting process. In this process, the micro-injection pump 1891 can be activated to allow chitosan to form a thin film structure through the mesh injection end hole 1892, which can then wrap around nerves or bones. This allows bone fragments generated during bone cutting to a certain extent to adhere and aggregate, facilitating subsequent collection and preventing bone fragments from affecting the surgery, thus reducing surgical risks and complications. Later, when the electric bone cutter 13 is operating, if heat is detected at the cutting site and the temperature exceeds a preset safety threshold, the argon gas injection control tank 140 is activated to facilitate the operation of the argon gas injection control tank 140. Argon gas can be delivered from the argon injection control tank 140 to the argon injection end 147, thereby reducing the temperature of the electric bone cutter 13 and the cutting site, protecting surrounding tissues from heat damage. When the temperature changes, the rotation angle control motor 144 is activated, causing the rotation angle control motor 144 to drive the short adjusting horizontal rail 145 inside the rotating transverse groove frame 143 to rotate, thereby causing the argon injection end 147 to adjust its angle. This allows the adjusting guide post 146 to convert the power of the side motor into the lateral movement of the short adjusting horizontal rail 145. The argon gas injection end 147 is adjusted along the trajectory of the short adjusting rail 145 inside the adjusting guide post 146, forming a left-right displacement adjustment of the argon gas injection end 147. Combined with the aforementioned angle adjustment, precise position adjustment is achieved. After the angle and left-right displacement adjustments, the argon gas injection end 147 reaches the preset injection position. The injection connection control valve pipe 142 can control the argon gas flow rate based on the temperature monitoring data from the external temperature sensor to regulate the temperature of the electric bone cutter 13 and the cutting site, effectively reducing the damage to surrounding tissues caused by temperature rise.
