[0037] Figure 1 A schematic diagram schematically shows the structure of an ultrasonic osteotome power testing device according to an embodiment of the present invention, Figure 2 A schematic diagram schematically shows a fixing structure according to an embodiment of the present invention. Figure 3 A schematic diagram schematically shows a motion structure of an embodiment of the present invention, as shown in FIG. Figure 1-3 As shown, an ultrasonic bone knife power testing device of the present invention comprises:

[0038] A base 10, a moving structure 20, a fixed structure 30 and a detection structure 40;

[0039] The motion structure 20 includes a first bracket 201, a slider 202 and a motor 203. The first bracket 201 is fixed on the base 10. The slider 202 is slidably connected to the first bracket 201. The motor 203 drives the slider 202 to perform vertical reciprocating motion along the first bracket 201.

[0040] The fixing structure 30 includes a second bracket 301, the second bracket 301 is fixedly connected to the slider 202, and the second bracket 301 is used to fix the ultrasonic osteotome;

[0041] The detection structure 40 is connected to the second bracket 301, and is used to detect the cutting force of the ultrasonic bone knife when it moves.

[0042] Specifically, in traditional technology, the measurement of the ultrasonic bone knife is usually performed by the user holding the ultrasonic bone knife for moving and feeding. During this operation, the user cannot ensure that the feeding speed is the same each time, cannot ensure that the ultrasonic bone knife moves at a uniform speed, and cannot ensure that the cutting force of the ultrasonic bone knife is consistent during cutting. This makes the final measured result inaccurate and cannot ensure the safety of subsequent surgery using the ultrasonic bone knife.

[0043] In view of the above problems, the present invention designs a device capable of automatically controlling the feeding of an ultrasonic bone knife, wherein a motor 203 controls a slider 202 to make vertical reciprocating motion along a first bracket 201, and the slider 202 is fixedly connected to a fixed structure 30, so that the ultrasonic bone knife on the fixed structure 30 also moves vertically with the movement of the slider 202, thereby realizing the feeding and cutting of the ultrasonic bone knife;

[0044] At the same time, a detection structure 40 is provided on the fixed structure 30, which can detect the cutting force each time the ultrasonic bone knife is fed for cutting, and reflect the data to the computer program for monitoring. The overall device effectively solves the problem of uneven speed and force when the handheld ultrasonic bone knife moves. Through this device, the power of the ultrasonic bone knife and the working effect of each gear can be accurately measured to ensure the safety of subsequent operations.

[0045] Furthermore, if Figure 2 As shown, a first groove 302 is provided on the second bracket 301, and the size of the first groove 302 matches the outer contour of the ultrasonic osteotome;

[0046] A locking structure 303 is also provided on the second bracket 301 , and the locking structure 303 is used to fix the ultrasonic osteotome in the first groove 302 .

[0047] Specifically, the first groove 302 is arranged along the axial direction of the second bracket 301, and its size matches the outer contour of the ultrasonic bone knife. Part of the side surface of the first groove 302 is exposed from the side surface of the second bracket 301, so that the ultrasonic bone knife can be inserted into the first groove 302 from the side surface of the second bracket 301 to complete the installation.

[0048] At the same time, a locking structure 303 is also provided on the second bracket 301. When the ultrasonic bone knife is installed in the first groove 302, the locking structure 303 is used to fix the ultrasonic bone knife in the first groove 302 to prevent the ultrasonic bone knife from slipping and affecting the measurement.

[0049] Further, Figure 4 A schematic diagram schematically showing another perspective view of a fixing structure of an embodiment of the present invention, Figure 5 A schematic diagram schematically shows the structure of a tightening member according to an embodiment of the present invention, as shown in FIG. Figure 2 , 4 、5 as shown:

[0050] The locking structure 303 includes a third groove 3031, a collar 3032 and a locking component 3033;

[0051] The third groove 3031 is provided on the second bracket 301 , and the collar 3032 surrounds the second bracket 301 through the third groove 3031 ;

[0052] The locking component 3033 includes a locking pin 30331 and a pressing member 30332. The pressing member 30332 is located between the collar 3032 and the first groove 302. The outer contour of the pressing member 30332 facing the side wall of the first groove 302 matches the outer contour of the ultrasonic bone knife.

[0053] The locking pin 30331 is vertically inserted into the collar 3032 and the tightening piece 30332 relative to the side wall of the first groove 302 , and the insertion end of the locking pin 30331 abuts against the tightening piece 30332 to fix the ultrasonic bone knife in the first groove 302 .

[0054] The collar 3032 is slidably connected to the third groove 3031 , and the collar 3032 performs vertical reciprocating motion along the side wall of the third groove 3031 .

[0055] Specifically, the third groove 3031 is axially arranged on the second bracket 301 and is located between the inner wall of the first groove 302 and the side wall of the second bracket 301. The collar 3032 is arranged in a circular ring shape, inserted into the third groove 3031, and sleeved on the second bracket 301, and can vertically reciprocate along the third groove 3031 relative to the second bracket 301;

[0056] A through hole (not marked in the figure) is provided on the ring 3032, and the through hole is radially arranged on the ring 3032. A circular groove (not marked in the figure) is provided on the tightening piece 30332, and the circular groove is arranged corresponding to the through hole. By inserting the locking pin 30331 into the through hole and then entering the circular groove, the insertion end of the locking pin 30331 abuts against one end of the tightening piece 30332, and the other end of the tightening piece 30332 matches the outer contour shape of the ultrasonic bone knife, so that the tightening piece 30332 can half wrap the ultrasonic bone knife, and then the tightening piece 30332 squeezes the ultrasonic bone knife through the extrusion force of the locking pin 30331, and then the ultrasonic bone knife is fixed in the first groove 302.

[0057] At the same time, the collar 3032 can move along the second bracket 301, so that the position of the collar 3032 and the locking position of the locking component 3033 can be adjusted according to actual installation requirements.

[0058] Furthermore, a second groove 304 is provided on the second bracket 301, and the second groove 304 is located on the top of the first groove 302;

[0059] An opening 305 is further provided between the first groove 302 and the second groove 304 , and a cross-sectional area of ​​the opening 305 is smaller than a cross-sectional area of ​​the first groove 302 .

[0060] Specifically, Figure 2 As shown, part of the circumferential side wall of the second groove 304 extends to the outside of the second bracket 301, and an opening 305 is opened between the second groove 304 and the first groove 302, and the cross-sectional area of ​​the opening 305 is smaller than the cross-sectional area of ​​the first groove 302, so that there is a partition between the first groove 302 and the second groove 304. When the ultrasonic bone knife is installed in the first groove 302, the pipelines, wires, etc. connected to the ultrasonic bone knife are placed into the second groove 304 through the opening 305 and overlapped at the partition between the two, so that the wires, pipelines, etc. can be supported, thereby avoiding the influence of the self-weight of the wires, pipelines, etc. on the measurement of the detection structure 40, thereby ensuring the accuracy of the measurement data.

[0061] Furthermore, if Figure 3 As shown, a rotating shaft 204 is provided on the first bracket 201, and the slider 202 is sleeved on the rotating shaft 204;

[0062] The motor 203 is in driving connection with the rotating shaft 204 , and the motor 203 controls the rotating shaft 204 to rotate so as to drive the slider 202 to perform vertical reciprocating motion.

[0063] A slide rail 205 is also provided on the first bracket 201 , and the slider 202 is cooperatively connected with the slide rail 205 , and the slider 202 moves along the slide rail 205 .

[0064] The motor 203 is located at one end of the first bracket 201 , and the motor 203 is disposed in the base 10 .

[0065] Specifically, the rotating shaft 204 is arranged parallel to the first bracket 201, one end of which is connected to the first bracket 201, and the other end extends into the base 10 and is connected to the motor 203. When the motor 203 is running, the rotating shaft 204 is controlled to rotate, and the slider 202 on the rotating shaft 204 is restricted from moving by the slide rail 205, so that the slider 202 can move vertically along the rotating shaft 204, thereby controlling the feeding of the ultrasonic bone knife on the fixed structure 30.

[0066] A coupling 206 is further disposed between the rotating shaft 204 and the motor 203 for fixedly connecting the rotating shaft 204 and the motor 203 . The coupling 206 is also disposed in the base 10 .

[0067] Further, Figure 6 A schematic diagram schematically shows the structure of a base according to an embodiment of the present invention, as shown in FIG. Figure 6 As shown, a control module (not shown in the figure) is provided in the base 10, and the control module is in communication connection with the motor 203, and the control module controls the start and stop of the motor 203 to control the feeding of the ultrasonic bone knife.

[0068] The buttons 101 are arranged on the surface of the base 10, including an upward movement button 1011, a downward movement button 1012 and an emergency stop button 1013, which can respectively control the motor 203 to drive the slider 202 to move upward, downward and emergency stop.

[0069] Furthermore, one end of the detection structure 40 is fixedly connected to the top of the second bracket 301 , and the other end is fixedly connected to the slider 202 via a connecting member 207 .

[0070] The detection structure 40 is configured as a force sensor.

[0071] Specifically, when the slider 202 controls the feed of the ultrasonic bone knife on the fixed structure 30, when the ultrasonic bone knife contacts and cuts the object to be cut, the fixed structure 30 and the detection structure 40 are subjected to the reaction force of the object to be cut, and the detection structure 40 is squeezed, so that the reaction force of the object to be cut given to the ultrasonic bone knife can be converted into the cutting force of the ultrasonic bone knife, thereby realizing measurement.

[0072] In order to ensure that the detection structure 40 can be squeezed, the connecting piece 207 is set in a "7" shape, the vertical side wall of the connecting piece 207 is fixedly connected to the slider 202, and the horizontal side wall of the connecting piece 207 is fixedly connected to the detection structure 40. When the ultrasonic bone knife cuts the object to be cut, the reaction force it receives and the reaction force given to the detection structure 40 by the horizontal side wall of the connecting piece 207 jointly squeeze the detection structure 40, thereby realizing the measurement of the detection structure 40.

[0073] Furthermore, the first bracket 201 is fixedly connected to the base 10 via an L-shaped plate 208 .

[0074] Two or three L-shaped plates 208 may be provided, one end of which is fixedly connected to the side wall of the first bracket 201 not facing the rotating shaft 204 , and the other end is fixedly connected to the upper surface of the base 10 , thereby fixing the first bracket 201 .

[0075] In summary, the ultrasonic bone knife power testing device of the present invention includes a base 10, a moving structure 20, a fixed structure 30 and a detection structure 40. The moving structure 20 is arranged on the base 10 and can perform vertical reciprocating motion. The fixed structure 30 is fixed on the moving structure 20. The fixed structure 30 is used to fix the ultrasonic bone knife. The moving structure 20 moves vertically, thereby controlling the ultrasonic bone knife on the fixed structure 30 to perform feeding and cutting operations. The detection structure 40 is connected to the fixed structure 30, which can detect the cutting force of the ultrasonic bone knife during feeding. Through the above device, the ultrasonic bone knife can be automatically controlled to feed and cut at a uniform speed and force, and accurate test data of the bone knife power and efficiency of each gear can be obtained, which is conducive to ensuring the safety of subsequent operations.
