For example, bone tissue can be cut, drilled, or crushed by the medical ultrasonic scalpel, thus achieving the purpose of treating bone tissue.

[0004]

[0004] In related technology, when bone tissue is cut or fragmented, the bone tissue is crushed or drilled using a medical ultrasonic scalpel, and the bone tissue is broken or processed into smaller bone pieces to enable handling of the bone tissue.

[0005]

[0005] However, in related techniques, bone tissue is processed slowly and inefficiently.

[0006]

[0006] The present application aims to solve at least one of the technical problems existing in the background art. To achieve this objective, the present application aims to provide a medical ultrasonic scalpel, a medical ultrasonic scalpel system, and a robot-assisted ultrasonic scalpel system to alleviate the problem of low work efficiency of medical ultrasonic scalpels in the related art.

[0007]

[0007] In a first aspect, an embodiment of the present application provides a medical ultrasonic scalpel including a blade having a first end face and a cutting groove, the cutting groove passing through the first end face, the cutting groove enabling the first end face to form at least one annular cutting surface.

[0008]

[0008] In some embodiments, the blade also has a second end face and a flank face, the first end face is opposite the second end face, the flank face connects the first end face and the second end face, and the cutting groove is a through hole, one end of which passes through the first end face and the other end of which passes through one of the second end face and the flank face.

[0009]

[0009] In some embodiments, the blade has at least two through holes, the other ends of which pass through the relief surface, and the through holes enable the relief surface to form a chip discharge portion.

[0010] In some embodiments, the first end face has an area larger than an area of ​​the second end face, and the other end of the through hole passes through a portion of the flank surface near the second end face.

[0011] In some embodiments, the distance L1 between the axes of any two through holes in the direction X from the first end face to the second end face initially remains the same and then gradually increases.

[0012] In some embodiments, the junction of the through hole and the flank forms a cutout.

[0013] In some embodiments, the scraping portion is serrated or the scraping portion has a chamfer.

[0014] In some embodiments, the blade has a through hole, the other end of which passes through the second end face.

[0015] In some embodiments, the cutting surface is serrated, or the cutting surface is a file surface, or the edges of the cutting surface have chamfers.

[0016] In some embodiments, the orthogonal projection of the kerf of the first end surface comprises at least one of a circle, an oval, a rectangle, and a rounded rectangle.

[0017] In some embodiments, the medical ultrasonic scalpel further includes a bit bar connected to an end of the blade remote from the first end surface.

[0018]

[0018] In some embodiments, the medical ultrasonic scalpel further includes a bit body, the bit body connecting the bit bar and the blade, and in a direction parallel to the first end face, the bit body having a cross-sectional area smaller than the area of ​​the first end face.

[0019]

[0019] In a second aspect, an embodiment of the present application provides a medical ultrasonic scalpel system including a vibration source and a medical ultrasonic scalpel of any one of the embodiments described above, wherein the vibration source is connected to the blade of the medical ultrasonic scalpel and is configured to generate vibrations.

[0021] A cutting groove is disposed in the blade of the medical ultrasonic scalpel according to an embodiment of the present application, and the cutting groove penetrates the first end surface to form an annular cutting surface, which cuts or fragments bone tissue, and the center of the cutting surface is hollow. When bone tissue is cut or fragmented, the bone tissue corresponding to the position where the cutting groove is located (i.e., the center of the cutting surface) does not come into contact with the cutting surface, i.e., it does not need to be cut or fragmented, but the bone tissue corresponding to the periphery of the cutting groove (i.e., the annular cutting surface) may come into contact with the cutting surface to be cut or fragmented. In this way, the cutting surface creates a small cutting area in the bone tissue, but can still cut or fragment the bone tissue into large bone fragments. Due to the small cutting or fragmenting area of ​​the bone tissue caused by the cutting surface, the medical ultrasonic scalpel according to an embodiment of the present application achieves time savings and improved work efficiency when cutting or fragmenting bone tissue into bone fragments of the same size.

[0053]

[0053] Only some exemplary embodiments are briefly described below. As will be understood by those skilled in the art, the described embodiments can be modified in various ways without departing from the spirit or scope of the present application. Accordingly, the accompanying figures and descriptions are to be regarded as illustrative in nature, and not as restrictive.

[0054]

[0054] From the perspective of current market development, medical ultrasonic scalpels have been gradually applied in surgical operations. Furthermore, due to the characteristics of ultrasound, when a medical ultrasonic scalpel comes into contact with bone tissue, which has high hardness, the bone tissue is less likely to deform, thereby producing cutting or fragmentation at the contact location. When a medical ultrasonic scalpel comes into contact with soft tissue, the soft tissue bounces up or is deformed under the elastic action of the soft tissue, and vibrates slightly with the vibration of the medical ultrasonic scalpel, thereby offsetting the energy in the blade and avoiding cutting or fragmentation. Therefore, medical ultrasonic scalpels have great advantages in bone cutting, especially in surgical operations where the surgical site is located near the interface between bone and soft tissue.

[0055]

[0055] The applicant notes that in the related art, when bone tissue is cut or fragmented using a medical ultrasonic scalpel, the bone tissue is mainly perforated using the blade of the medical ultrasonic scalpel, and the bone tissue that needs to be cut or fragmented is pulverized or cut into smaller bone pieces to enable handling of the bone tissue. However, because bone tissue is hard, the bone tissue is cut or fragmented slowly and inefficiently.

[0056]

[0056] To improve the work efficiency of a medical ultrasonic scalpel, an embodiment of the present application provides a medical ultrasonic scalpel including a blade having a first end surface and a cutting groove, the cutting groove passing through the first end surface and allowing the first end surface to form at least one annular cutting surface. When bone tissue is cut or fragmented, the bone tissue corresponding to the position where the cutting groove is located does not contact the cutting surface, i.e., it does not need to be cut or fragmented, and the bone tissue corresponding to the periphery of the cutting groove (i.e., the annular cutting surface) may contact the cutting surface to be cut or fragmented. In this way, the cutting surface creates a small cutting area in the bone tissue but can still cut or fragment the bone tissue into large bone fragments. Due to the small cutting or fragmenting area of ​​the bone tissue created by the cutting surface, the medical ultrasonic scalpel according to the embodiment of the present application achieves time savings, speed, and improved work efficiency when cutting or fragmenting bone tissue into bone fragments of the same size.

[0057]

[0057] An embodiment of the present application provides a medical ultrasonic scalpel, and Figure 1 is a schematic structural diagram of a medical ultrasonic scalpel according to an embodiment of the present application. Referring to Figure 1, the medical ultrasonic scalpel includes a blade 10. Figure 2 is a schematic structural diagram of the blade according to an embodiment of the present application, and Figure 3 is a right side view of the blade according to an embodiment of the present application. Referring to Figures 2 and 3, the blade 10 has a first end face 101 and a cutting groove 102, the cutting groove 102 passing through the first end face 101, and the cutting groove 102 allows the first end face 101 to form at least one annular cutting surface 103.

[0058]

[0058] In the embodiment of the present application, the cutting surface 103 is configured to cut or fragment bone tissue. In practical applications, the vibration of the blade 10 drives the cutting surface 103 to vibrate, and the bone tissue is cut or fragmented during the vibration of the cutting surface 103.

[0059]

[0059] In the embodiment of the present application, the cutting groove 102 is disposed in the blade 10, the cutting groove 102 penetrates the first end face 101 to form an annular cutting surface 103, the cutting surface 103 cuts or fragments the bone tissue, and the center of the cutting surface 103 is hollow. When the bone tissue is cut or fragmented, the bone tissue corresponding to the position where the cutting groove 102 is located (i.e., the center of the cutting surface 103) does not come into contact with the cutting surface 103, i.e., it does not need to be cut or fragmented, but the bone tissue corresponding to the periphery of the cutting groove 102 (i.e., the annular cutting surface 103) may come into contact with the cutting surface 103 to be cut or fragmented. In this way, the cutting surface 103 creates a small cutting or fragmenting area in the bone tissue, but can still cut or fragment the bone tissue into large bone fragments, and due to the small cutting or fragmenting area of ​​the bone tissue created by the cutting surface 103, the medical ultrasonic scalpel according to the embodiment of the present application achieves shorter time, faster speed, and improved work efficiency when cutting or fragmenting bone tissue into bone fragments of the same size.

[0060]

[0060] The medical ultrasonic scalpel according to the embodiment of the present application has a large cutting surface 103, which allows cutting or fragmenting a wide groove in bone tissue.

[0061]

[0061] In the implementation form of the present application, the cutting surface 103 is serrated, thereby increasing the friction of the cutting surface 103 so that the medical ultrasonic scalpel is stable and does not slip when the medical ultrasonic scalpel is used.

[0062]

[0062] In another implementation form of the present application, when the cutting surface 103 is a file surface, the friction of the cutting surface 103 can also be increased, while the file-surface cutting surface 103 cuts or fragments bone tissue faster, improving the working efficiency of the medical ultrasonic scalpel.

[0063] In another implementation of the present application, the edges of the cutting surface 103 have chamfers.

[0064]

[0064] In the implementation form of the present application, the ring width D of the annular cutting surface 103 is equal to or greater than 0.3 millimeters (mm) and equal to or less than 0.6 millimeters, for example, the ring width D of the annular cutting surface 103 is equal to 0.45 millimeters. This ensures the strength of the cutting surface 103, and also prevents the cutting surface 103 from becoming too large and making it difficult to operate the medical ultrasonic scalpel.

[0065]

[0065] According to some embodiments of the present application, referring to Figures 2 and 3, the blade 10 also has a second end face 104 and a flank face 105, the first end face 101 being opposite the second end face 104, and the flank face 105 connecting the first end face 101 and the second end face 104.

[0066]

[0066] Fig. 4 is a front view of a medical ultrasonic scalpel according to an embodiment of the present application, Fig. 5 is a cross-sectional view of the medical ultrasonic scalpel of Fig. 4 along section AA, and Fig. 6 is a top view of the medical ultrasonic scalpel of Fig. 4. Referring to Figs. 2 to 6, the cutting groove 102 is a through hole, one end of which passes through the first end face 101 and the other end of which passes through the second end face 104.

[0067]

[0067] After the bone tissue is cut or fragmented, the cut bone fragments enter the cutting groove 102 from the first end face 101. In an embodiment of the present application, the cutting groove 102 is arranged as a through hole, and after the bone tissue is cut or fragmented, a tool can be used to push the bone fragments in the through hole out from the second end face 104 to facilitate cleaning the blade.

[0068]

[0068] In another embodiment of the present application, the cutting groove 102 may not be a through hole, i.e., the cutting groove 102 passes only through the first end face 101, and after the bone tissue has been cut or fragmented, the bone fragments within the cutting groove 102 can be extracted from the first end face 101 using a tool.

[0069]

[0069] In the blade 10 shown in Figures 1 to 6, the annular cutting surface 103 resembles the shape of a racetrack, i.e., the center of the cutting surface 103 is rectangular in shape, and the two ends of the rectangle are each connected by a semicircle.

[0070]

[0070] For example, the length L2 of the racetrack-shaped cut surface 103 is 4 mm or more and 6 mm or less, and the width L3 of the racetrack-shaped cut surface 103 is 2 mm or more and 4 mm or less.

[0071] For example, the length L2 of the racetrack-shaped cut surface 103 is equal to 5 mm, and the width L3 of the racetrack-shaped cut surface 103 is equal to 2.9 mm.

[0072]

[0072] The blade 10 shown in Figs. 1 to 6 has a through hole.

[0073]

[0073] Figure 7 is a schematic structural diagram of another medical ultrasonic scalpel according to an embodiment of the present application. Figure 8 is a schematic structural diagram of a blade according to an embodiment of the present application. Figure 9 is a partially enlarged view of the blade section of the medical ultrasonic scalpel of Figure 7. Figure 10 is a front view of the blade section of the medical ultrasonic scalpel of Figure 7. Figure 11 is a top view of the blade section of the medical ultrasonic scalpel of Figure 7. Figure 12 is a front view of another medical ultrasonic scalpel according to an embodiment of the present application. Figure 13 is a cross-sectional view of the medical ultrasonic scalpel of Figure 12 along section BB. Figure 14 is a right side view of a blade according to an embodiment of the present application. Figure 15 is a left side view of a blade according to an embodiment of the present application.

[0074] 7 to 15, the blade 10 has two through holes, the other ends of which pass through the clearance surface 105, allowing the clearance surface 105 to form a chip discharge portion 106.

[0075]

[0075] As the cut or fragmented bone chips enter the through-hole, in this embodiment of the present application, the other end of the through-hole passes through the flank 105, i.e., neither end of the through-hole is hidden. The cut or fragmented bone chips can be discharged from the chip discharge portion 106 to achieve automatic cleaning of the bone chips, which is more convenient to use.

[0076] 7 to 15, the annular cross section 103 is a rounded rectangle. For example, the length L4 of the rounded rectangular cross section 103 is 4 mm or more and 6 mm or less, and the width L5 of the rounded rectangular cross section 103 is 2 mm or more and 4 mm or less.

[0077] For example, the length L4 of the rounded rectangular cut surface 103 is equal to 5 mm, and the width L5 of the rounded rectangular cut surface 103 is equal to 2.9 mm.

[0078]

[0078] In the embodiment of the present application, the first end face 101 has an area larger than the area of ​​the second end face 104, and the other end of the through hole passes through a portion of the clearance face 105 near the second end face 104.

[0079]

[0079] In this embodiment of the present application, the area of ​​the first end face 101 is larger than the area of ​​the second end face 104, and the cutting surface 103 is located on the first end face 101, so that when bone tissue is perforated using a medical ultrasonic scalpel according to an embodiment of the present disclosure, perforation can continue until the required perforation depth is reached, even if the perforation depth exceeds the height of the blade 10.

[0080]

[0080] In this embodiment of the present application, the junction of the through hole and the flank 105 forms the scraping portion 107, i.e., the scraping portion 107 is part of the flank 105. When a medical ultrasonic scalpel is used, it may be necessary to scrape away bone tissue, and the medical ultrasonic scalpel according to the embodiment of the present application may be more convenient for scraping away bone tissue through the scraping portion 107.

[0081]

[0081] In the implementation form of the present application, the scraping portion 107 is serrated, thereby increasing the friction of the scraping portion 107 so that the medical ultrasonic scalpel is stable and does not slip when the medical ultrasonic scalpel is used.

[0082]

[0082] In another implementation of the present application, the scraped portion 107 has a chamfer.

[0083]

[0083] In some embodiments of the present application, referring to Figure 13, the distance L1 between the axes of any two through holes in the direction X from the first end face 101 to the second end face 104 initially remains the same and then gradually increases.

[0084]

[0084] For example, the distance L1 between the axes of any two through holes is constant from the first end face 101 to the midpoint between the first end face 101 and the second end face 104, and the distance L1 between the axes of any two through holes gradually increases from the midpoint between the first end face 101 and the second end face 104 to the second end face 104.

[0085]

[0085] In this embodiment of the present application, the end of the through hole away from the first end face 101 is close to the clearance face 105, i.e., the portion of the through hole near the second end face 104 is tilted outward, and the bone fragments within the through hole are also tilted outward when moved, thereby making the bone fragments within the through hole easier to remove.

[0086]

[0086] The blade 10 shown in Figs. 7 to 15 has two through holes.

[0087] The two through holes form two annular cut surfaces 103 on the first end surface 101.

Figure 17 is a schematic structural diagram of a blade according to an embodiment of the present application. Figure 18 is a partially enlarged view of the blade section of the medical ultrasonic scalpel of Figure 16. Figure 19 is a front view of the blade section of the medical ultrasonic scalpel of Figure 16. Figure 20 is a front view of another medical ultrasonic scalpel according to an embodiment of the present application. Figure 21 is a right side view of a blade according to an embodiment of the present application. Figure 22 is a left side view of a blade according to an embodiment of the present application.

[0089]

[0089] Referring to Figures 16 to 22, the blade 10 has four through holes in the first end face 101, which form four annular cut surfaces 103.

[0090] In other implementations, the blade 10 may have three through holes, five through holes, or more through holes, which is not a limitation in this application. The multiple through holes may be symmetrically distributed around the central axis of the blade 10.

[0091]

[0091] In the blade 10 shown in Figures 16-22, the annular cutting surface 103 has a rounded square shape. Illustratively, the side length L6 of the rounded square cutting surface 103 is equal to or greater than 4 mm and equal to or less than 6 mm. For example, the side length L6 of the rounded square cutting surface 103 is equal to 5 mm.

[0092]

[0092] In the blade 10 shown in Figures 7 to 22, the annular cross section 103 is polygonal.

Figure 24 is a schematic structural diagram of a blade according to an embodiment of the present application.

Figure 26 is a front view of the blade section of the medical ultrasonic scalpel of Figure 23. Figure 27 is a front view of another medical ultrasonic scalpel according to an embodiment of the present application. Figure 28 is a right side view of a blade according to an embodiment of the present application. Figure 29 is a left side view of a blade according to an embodiment of the present application.

[0094] 23 to 29, the annular cut surface 103 is circular. Illustratively, the diameter R of the circular cut surface 103 is equal to or greater than 4 mm and equal to or less than 8 mm. For example, the diameter R of the circular cut surface 103 is equal to 6.2 mm.

[0095]

[0095] The description of the cross section 103 in the above embodiment is a description of the overall shape of the cross section 103.

[0096]

[0096] In this embodiment of the present application, the shape of the orthogonal projection of the kerf 102 on the first end surface 101 is not limited and may include at least one of a circle, an ellipse, a rectangle, and a rounded rectangle.

[0097]

[0097] In another implementation, the shape of the orthogonal projection of the kerf 102 on the first end face 101 may also be an irregular shape.

[0098]

[0098] In some embodiments of the present application, referring to Figures 7, 12, 13, 16, 20, 23 and 27, the medical ultrasonic scalpel further includes a bit bar 20, which is connected to the end of the blade 10 away from the first end face 101.

[0099]

[0099] In this embodiment of the present application, the bit bar 20 may be used for connecting to other devices, facilitating the connection of the medical ultrasonic scalpel with other devices. For example, the other devices may be vibration sources.

[0100]

[0100] By way of example, the end of the bit bar 20 remote from the blade 10 is connected to an external thread 201, and the bit bar 20 may be connected to another device by means of the thread.

[0101]

[0101] In some embodiments of the present application, referring to Figures 7, 12, 13, 16, 20, 23, and 27, the medical ultrasonic scalpel further includes a bit body 30, which connects the bit bar 20 and the blade 10, and in a direction parallel to the first end face 101, the bit body 30 has a cross-sectional area smaller than the area of ​​the first end face 101.

[0102]

[0102] In this embodiment of the present application, the cross-sectional area of ​​the bit body 30 is smaller than the area of ​​the first end face 101, and the cutting surface 103 is located on the first end face 101, so that when bone tissue is drilled using the medical ultrasonic scalpel according to the embodiment of the present disclosure, drilling can be continued until the required drilling depth is reached, even if the drilling depth exceeds the height of the blade 10. At the same time, the bit body 30 is connected to the vibration source and the blade 10, and the size of the bit body 30 is small so as to adjust the vibration of the blade 10 through the bit body 30.

[0103]

[0103] In this implementation of this embodiment of the present application, the central axis of the cutting groove 102 is parallel to the central axis of the bit body 30, reducing resistance when the medical ultrasonic scalpel is used.

[0104]
