[0002] The ultrasonic osteotome uses high-intensity focused ultrasound technology to convert electrical energy into mechanical energy through a transducer. After high-frequency ultrasonic oscillation, the water vapor in the contacted tissue cells is vaporized, thereby completely destroying the bone tissue that needs to be cut during the operation. When in use, the high-intensity focused ultrasonic wave only has a destructive effect on bone tissue with a specific hardness.

[0037] Figure 1 Schematic structural diagram of an ultrasonic bone scalpel power test device showing an embodiment of the present invention Figure 2 Schematic structural diagram of a fixing structure showing an embodiment of the present invention Figure 3 Schematic structural diagram of a movement structure showing an embodiment of the present invention. As Figures 1-3 shown, an ultrasonic bone scalpel power test device of the present invention includes:

[0038] base 10, movement structure 20, fixing structure 30 and detection structure 40;

[0039] The movement 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 movement 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. The second bracket 301 is used to fix the ultrasonic bone scalpel;

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

[0042] Specifically, in the traditional technology, the measurement of the ultrasonic bone scalpel is usually carried out by the user holding the ultrasonic bone scalpel and moving it forward. During this operation, the user cannot ensure that the speed is the same each time when feeding, cannot ensure that the ultrasonic bone scalpel moves at a uniform speed, and even less can ensure that the cutting force of the ultrasonic bone scalpel is the same when cutting. This makes the accuracy of the finally measured result not high and cannot ensure the safety during subsequent surgeries using this ultrasonic bone scalpel.

[0043] In view of the above problems, the present invention designs a device capable of automatically controlling the feeding of the ultrasonic bone scalpel. The motor 203 controls the slider 202 to make a vertical reciprocating motion along the first bracket 201. The fixing structure 30 is fixedly connected through the slider 202, so that the ultrasonic bone scalpel on the fixing structure 30 also moves vertically along with the slider 202 to realize the feeding and cutting of the ultrasonic bone scalpel.

[0044] At the same time, a detection structure 40 is provided on the fixing structure 30, which can detect the magnitude of the cutting force during each feeding and cutting of the ultrasonic bone scalpel and reflect this data to the computer program for monitoring. The overall device effectively solves the problems of uneven speed and strength when manually operating the ultrasonic bone scalpel to move. Through this device, the power of the ultrasonic bone scalpel and the working effect of each gear can be accurately measured to ensure the safety of subsequent surgeries.

[0045] Furthermore, as Figure 2 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 bone scalpel;

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

[0047] Specifically, the first groove 302 is arranged along the axial direction of the second bracket 301, its size matches the outer contour of the ultrasonic bone scalpel, and a 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 scalpel 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. After the ultrasonic bone scalpel is installed in the first groove 302, the locking structure 303 is used to fix the ultrasonic bone scalpel in the first groove 302 to prevent the ultrasonic bone scalpel from slipping and affecting the measurement.

[0049] Furthermore, Figure 4 Schematically shows a structural diagram of another perspective of the fixing structure of an embodiment of the present invention, Figure 5 Schematically shows a structural diagram of a top pressing member of an embodiment of the present invention, as Figure 2 、 4 、5 shown:

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

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

[0054] The collar 3032 is slidably connected to the third groove 3031, and the collar 3032 reciprocates vertically along the side wall of the third groove 3031.

[0055] Specifically, the third groove 3031 is axially provided 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 set as a circular ring, inserted into the third groove 3031, and sleeved on the second bracket 301, and can reciprocate vertically relative to the second bracket 301 along the third groove 3031;

[0056] A through hole (not marked in the figure) is provided on the collar 3032. The through hole is radially provided on the collar 3032. A circular groove (not marked in the figure) is provided on the pressing member 30332. The circular groove corresponds to the through hole. By inserting the locking pin 30331 into the through hole and then into the circular groove, the insertion end of the locking pin 30331 abuts against one end of the pressing member 30332, and the other end of the pressing member 30332 matches the outer contour of the ultrasonic osteotome, so that the pressing member 30332 can semi-wrap the ultrasonic osteotome, and then the pressing member 30332 presses the ultrasonic osteotome through the extrusion force of the locking pin 30331, and then fixes the ultrasonic osteotome in the first groove 302.

[0057] At the same time, the collar 3032 can move along the second bracket 301, and thus can adjust the position of the collar 3032 and the locking position of the locking member 3033 according to actual installation requirements.

[0058] Furthermore, a second groove 304 is further provided on the second bracket 301, and the second groove 304 is located at 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 the cross-sectional area of the opening 305 is smaller than that of the first groove 302.

[0060] Specifically, as Figure 2 shown, a part of the circumferential side wall of the second groove 304 extends to the outside of the second bracket 301. An opening 305 is formed between the second groove 304 and the first groove 302, and the cross-sectional area of the opening 305 is smaller than that of the first groove 302, so that there is a partition between the first groove 302 and the second groove 304. After the ultrasonic bone scalpel is installed in the first groove 302, the pipelines, wires, etc. connected to the ultrasonic bone scalpel are placed into the second groove 304 through the opening 305 and lapped at the partition between the two, which can support the wires, pipelines, etc., and avoid affecting the measurement of the detection structure 40 due to the self-weight of the wires, pipelines, etc., thereby ensuring the accuracy of the measurement data.

[0061] Furthermore, as Figure 3 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 rotation of the rotating shaft 204 to drive the slider 202 to perform vertical reciprocating motion.

[0063] A slide rail 205 is further provided on the first bracket 201, and the slider 202 is in mating connection 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 arranged in the base 10.

[0065] Specifically, the rotating shaft 204 is arranged parallel to the first bracket 201. One end of the rotating shaft 204 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 operates, it controls the rotation of the rotating shaft 204. 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 scalpel on the fixing structure 30.

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

[0067] Furthermore, Figure 6 The schematic structural diagram of the base showing an embodiment of the present invention is as Figure 6 shown. A control module (not shown in the figure) is arranged in the base 10. 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 scalpel.

[0068] A button 101 is provided on the surface of the base 10, which includes an upward movement button 1011, a downward movement button 1012, and an emergency stop button 1013, and can respectively control the motor 203 to drive the slider 202 to move upward, downward, and stop suddenly, etc.

[0069] Further, 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 through a connecting member 207.

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

[0071] Specifically, when the slider 202 controls the feeding of the ultrasonic bone cutter on the fixing structure 30, when the ultrasonic bone cutter contacts and cuts the object to be cut, the fixing structure 30 and the detection structure 40 are subjected to the reaction force of the object to be measured, and the detection structure 40 is squeezed, and can convert the reaction force given by the object to be cut to the ultrasonic bone cutter into the magnitude of the cutting force of the ultrasonic bone cutter, thereby realizing the measurement.

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

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

[0074] Two or three L-shaped plates 208 can be provided. One end of the L-shaped plate 208 is fixedly connected to the side wall of the first bracket 201 that does not face the rotating shaft 204, and the other end is fixedly connected to the upper surface of the base 10, thereby realizing the fixation of the first bracket 201.

[0075] In summary, the ultrasonic bone cutter power test device of the present invention includes a base 10, a motion structure 20, a fixing structure 30, and a detection structure 40. The motion structure 20 is arranged on the base 10 and can perform reciprocating vertical motion. The fixing structure 30 is fixed on the motion structure 20, and the fixing structure 30 is used to fix the ultrasonic bone cutter. By the vertical motion of the motion structure 20, the ultrasonic bone cutter on the fixing structure 30 is controlled to perform feeding and cutting operations. A detection structure 40 is connected to the fixing structure 30, and can detect the magnitude of the cutting force when the ultrasonic bone cutter feeds. Through the above device, the ultrasonic bone cutter can be automatically controlled to perform feeding and cutting at a constant speed and with a constant force, and accurate test data of the power and efficiency of each gear of the bone cutter can be obtained, which is beneficial to ensuring the safety of subsequent surgeries.
