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

[0011]

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

[0012]

[0012] In some embodiments, the joint between the through hole and the relief surface forms a machined portion.

[0013]

[0013] In some embodiments, the portion to be removed is serrated or has a chamfered edge.

[0014]

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

[0015]

[0015] In some embodiments, the cut surface is serrated, or the cut surface is a file surface, or the edges of the cut surface have chamfered portions.

[0016]

[0016] In some embodiments, the orthographic projection of the cutting groove on the first end face includes at least one of a circular, elliptical, rectangular, and rounded rectangular shape.

[0017]

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

[0053]

[0053] Only a few exemplary embodiments are briefly described below. The embodiments described can be modified in various ways without departing from the spirit or scope of this application, as can be understood by those skilled in the art. Accordingly, the accompanying figures and descriptions are illustrative and not limiting.

[0054]

[0054] From the perspective of current market development, medical ultrasonic scalpels are gradually being applied in surgical procedures. Furthermore, due to the properties of ultrasound, when a medical ultrasonic scalpel comes into contact with bone tissue which has high hardness, the bone tissue is not easily deformed, thereby producing cutting or fragmentation at the point of contact. When a medical ultrasonic scalpel comes into contact with soft tissue, the soft tissue is either bounced up or deformed under the elastic action of the soft tissue, and the energy is offset at the blade by the slight vibration of the medical ultrasonic scalpel, thus avoiding cutting or fragmentation. Therefore, medical ultrasonic scalpels have a great advantage in bone cutting, especially in surgical procedures where the surgical site is located near the interface between bone and soft tissue.

[0055]

[0055] The applicant notes that in the relevant 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 crushed or cut into smaller pieces to make the bone tissue easier to handle. However, because bone tissue is hard, it is cut or fragmented slowly and inefficiently.

[0056]

[0056] In order to improve the work efficiency of a medical ultrasonic scalpel, embodiments of the present application provide a medical ultrasonic scalpel comprising a blade having a first end face and a cutting groove, wherein the cutting groove passes through the first end face, and the cutting groove allows the first end face to form at least one annular cutting surface. When bone tissue is cut or fragmented, the bone tissue corresponding to the location where the cutting groove is located does not come into contact with the cutting surface, i.e., it does not need to be cut or fragmented, while 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 in order 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 larger bone fragments, and the small cutting or fragmentation area of ​​the bone tissue by the cutting surface allows the medical ultrasonic scalpel according to embodiments of the present application to achieve reduced time, increased speed, and improved work efficiency when cutting or fragmenting bone tissue into bone fragments of the same size.

[0057]

[0057] Embodiments of the present application provide a medical ultrasonic scalpel, and Figure 1 is a schematic 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 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 passes 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 embodiments of this 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 embodiments of this application, the cutting groove 102 is located within the blade 10 and penetrates the first end face 101 to form an annular cutting surface 103, the cutting surface 103 cuts or fragments 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 location 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 in order to be cut or fragmented. In this way, the cutting surface 103 creates a small cutting or fragmentation area in the bone tissue, but it is still possible to cut or fragment the bone tissue into larger bone fragments. Due to the small cutting or fragmentation area of ​​the bone tissue by the cutting surface 103, the medical ultrasonic scalpel according to the embodiment of this application achieves reduced time, increased 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 for cutting or fragmentation of a wide groove in bone tissue.

[0061]

[0061] In the implementation of this application, the cutting surface 103 is serrated, which increases 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 of this application, if the cutting surface 103 is a file surface, the friction of the cutting surface 103 can be increased, while the cutting surface 103 of the file surface cuts or fragments bone tissue at a faster rate, thereby improving the working efficiency of the medical ultrasonic scalpel.

[0063]

[0063] In another implementation of this application, the edges of the cut surface 103 have a chamfered portion.

[0064]

[0064] In the implementation of this application, the ring width D of the annular cut surface 103 is 0.3 millimeters (mm) or more and 0.6 millimeters or less, for example, the ring width D of the annular cut surface 103 is equal to 0.45 millimeters. The strength of the cut surface 103 is guaranteed, and the cut surface 103 is also prevented from becoming too large and from becoming cumbersome to operate with a 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 is on the opposite side of the second end face 104, and the flank face 105 connects the first end face 101 and the second end face 104.

[0066]

[0066] Figure 4 is a front view of a medical ultrasonic scalpel according to an embodiment of the present application, Figure 5 is a cross-sectional view of the medical ultrasonic scalpel of Figure 4 along section AA, and Figure 6 is a top view of the medical ultrasonic scalpel of Figure 4. Referring to Figures 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 the embodiments of this application, the cutting groove 102 is positioned as a through hole, which facilitates cleaning the blade by using a tool to push the bone fragments in the through hole out from the second end face 104 after the bone tissue has been cut or fragmented.

[0068]

[0068] In another embodiment of the present application, the cutting groove 102 does not have to be a through hole, that is, the cutting groove 102 passes only through the first end face 101, and after the bone tissue has been cut or fragmented, a tool can be used to remove the bone fragments in the cutting groove 102 from the first end face 101.

[0069]

[0069] In the blade 10 shown in Figures 1 to 6, the annular cross-section 103 resembles the shape of a race track; that is, the center of the cross-section 103 is rectangular, and the two ends of the rectangle are each connected to semicircles.

[0070]

[0070] As an example, the length L2 of the cross-section 103 of the racetrack shape is 4 mm or more and 6 mm or less, and the width L3 of the cross-section 103 of the racetrack shape is 2 mm or more and 4 mm or less.

[0071]

[0071] For example, the length L2 of the cross-section 103 of the racetrack shape is equal to 5 mm, and the width L3 of the cross-section 103 of the racetrack shape is equal to 2.9 mm.

[0072]

[0072] In the blade 10 shown in Figures 1 to 6, the blade 10 has a through hole.

[0073]

[0073] Figure 7 is a schematic diagram of the structure of another medical ultrasonic scalpel according to an embodiment of the present application. Figure 8 is a schematic diagram of the structure 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 the blade according to an embodiment of the present application. Figure 15 is a left side view of the blade according to an embodiment of the present application.

[0074]

[0074] Referring to Figures 7 to 15, the blade 10 has two through holes. The other end of the through hole passes through the relief face 105, and the through hole allows the relief face 105 to form a chip discharge portion 106.

[0075]

[0075] Since the cut or fragmented bone fragments enter the through-hole, in this embodiment of the present application, the other end of the through-hole passes through the relief face 105, i.e., neither end of the through-hole is concealed. The cut or fragmented bone fragments may thus be discharged from the chip discharge section 106 to achieve automatic cleaning of the bone fragments, which is more convenient to use.

[0076]

[0076] In the blade 10 shown in Figures 7 to 15, the annular cross-section 103 is a rounded rectangle. For example, the length L4 of the rounded rectangle cross-section 103 is 4 mm or more and 6 mm or less, and the width L5 of the rounded rectangle cross-section 103 is 2 mm or more and 4 mm or less.

[0077]

[0077] For example, the length L4 of the cross-section 103 of the rounded rectangle is equal to 5 mm, and the width L5 of the cross-section 103 of the rounded rectangle is equal to 2.9 mm.

[0078]

[0078] In the embodiments of this application, the first end face 101 has a larger area than the second end face 104, and the other end of the through hole passes through a portion of the relief 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 the medical ultrasonic scalpel according to the embodiment of the present disclosure, perforation can be continued 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 joint between the through hole and the relief surface 105 forms a scraping portion 107, that is, the scraping portion 107 is part of the relief surface 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 of this application, the cutting portion 107 is serrated, which increases the friction of the cutting portion 107, thereby stabilizing the medical ultrasonic scalpel and preventing it from slipping when in use.

[0082]

[0082] In another implementation of this application, the machined portion 107 has a chamfered portion.

[0083]

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

[0084]

[0084] Exemplarily, 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 relief face 105, that is, a portion of the through hole near the second end face 104 is tilted outward, and the bone fragments in the through hole are also tilted outward when moved, thereby making the bone fragments in the through hole easier to remove.

[0086]

[0086] In the blade 10 shown in Figures 7 to 15, the blade 10 has two through holes.

[0087]

[0087] The two through holes form two annular cross-sections 103 on the first end face 101.

[0088]

Figure 21 is a right side view of the blade according to an embodiment of the present application. Figure 22 is a left side view of the blade according to an embodiment of the present application.

[0089]

[0089] Referring to Figures 16 to 22, the blade 10 has four through holes that form four annular cross-sections 103 in the first end face 101.

[0090]

[0090] In other configurations, the blade 10 may have three through holes, five through holes, or more through holes, and this is not limited to the present application. The multiple through holes may be distributed symmetrically around the central axis of the blade 10.

[0091]

[0091] In the blade 10 shown in Figures 16 to 22, the annular cross-section 103 has a rounded square shape. As an example, the length L6 of the side of the rounded square cross-section 103 is 4 mm or more and 6 mm or less. For example, the length L6 of the side of the rounded square cross-section 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 28 is a right side view of the blade according to an embodiment of the present application. Figure 29 is a left side view of the blade according to an embodiment of the present application.

[0094]

[0094] Referring to Figures 23 to 29, the annular cross-section 103 is circular. As an example, the diameter R of the circular cross-section 103 is between 4 mm and 8 mm. For example, the diameter R of the circular cross-section 103 is equal to 6.2 mm.

[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 orthographic shape of the cutting groove 102 of the first end face 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 orthographic shape of the cutting groove 102 of the first end face 101 may also be an irregular shape.

[0098]

[0098] In some embodiments of this 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 to connect to other devices, facilitating the connection between the medical ultrasonic scalpel and other devices. For example, the other device may be a vibration source.

[0100]
