[0036] The present utility model provides a ultrasonic scalpel head.

[0037] Please refer to Figure 1 , Figure 1 which is a schematic structure of an embodiment of the ultrasonic scalpel head provided by the present utility model Figure 1 .

[0038] In an embodiment of the present utility model, the ultrasonic scalpel head 100 is connected to a knife rod 200. At least three side surfaces are provided along the circumferential direction of the ultrasonic scalpel head 100. Adjacent two side surfaces intersect and a cutting edge 108 is formed at the intersection. The ultrasonic scalpel head 100 is provided with at least three cutting edges 108, and the orientations of at least three cutting edges 108 are different.

[0039] In the technical solution of the present utility model, at least three side surfaces are provided on the side circumference of the ultrasonic scalpel head 100. A cutting edge 108 is formed at the intersection of adjacent two side surfaces, thereby forming at least three cutting edges 108, and the orientations of at least three cutting edges 108 are different. This enables the ultrasonic scalpel head 100 to meet the cutting requirements in more directions. During the operation, the ultrasonic scalpel head 100 does not need to be rotated to cut the surgical sites in different directions, which is convenient for the user to operate, simplifies the operation steps, shortens the operation time, and improves the success rate of the operation.

[0040] In one embodiment, the ultrasonic knife head 100 includes:

[0041] A blade body section 110, the proximal end of the blade body section 110 is connected to the tool bar 200, and the distal end extends in an arc shape towards the first direction;

[0042] A cutter head section 120, having opposite first and second ends, the first end of the cutter head section 120 is connected to the distal end of the blade body section 110, the second end of the cutter head section 120 extends in an arc shape towards the second direction, the second direction is opposite to the first direction, and the cutting edge 108 is provided on the cutter head section 120.

[0043] Referring to Figure 2 , in the embodiment of the present utility model, the ultrasonic knife head 100 includes a blade body section 110 and a cutter head section 120. The blade body section 110 has a proximal end and a distal end. The proximal end of the blade body section 110 is connected to the tool bar 200. The distal end of the blade body section 110 extends in an arc shape towards the first direction. The cutter head section 120 extends in an arc shape towards the second direction, so that the blade body section 110 and the cutter head section 120 are integrally arc-shaped, which is convenient for inserting the ultrasonic knife head 100 into the periphery of the blood vessel for surgical operations. At the same time, the arc-shaped structure can reduce the occlusion of the user's line of sight and provide a good surgical field of view for the user.

[0044] In one embodiment, at least one cutting edge 108 faces the first direction, at least one cutting edge 108 faces the second direction, and at least one cutting edge 108 faces the third direction, and the third direction is perpendicular to the first direction and the second direction.

[0045] Referring to Figure 2 and Figure 3 , in the embodiment of the present utility model, at least one cutting edge 108 faces the first direction, at least one cutting edge 108 faces the second direction, and at least one cutting edge 108 faces the third direction, so that the ultrasonic knife head 100 can meet the cutting operation requirements for the surgical sites in the first direction, the second direction, and the third direction, and further meet the actual surgical operation requirements.

[0046] In one embodiment, one of the sides is a plane and is parallel to the first direction to form a clamping surface 1011, and the clamping surface 1011 is used to cooperate with the ultrasonic knife chuck 300 to clamp the surgical site.

[0047] Combined with Figure 3 and Figure 5 , in the embodiment of the present utility model, the ultrasonic knife head 100 is provided with a clamping surface 1011, and the clamping surface 1011 cooperates with the ultrasonic knife chuck 300 of the ultrasonic knife to clamp the surgical site and coagulate the blood vessels at the surgical site to reduce bleeding during the operation.

[0048] In one embodiment, the clamping surface 1011 includes a first clamping sub-surface 123 and a second clamping sub-surface 111. The first clamping sub-surface 123 is provided on the cutter head section 120, and the second clamping sub-surface 111 is provided on the cutter body section 110. The width of the first clamping sub-surface 123 gradually decreases from the first end to the second end of the cutter head section 120; and / or,

[0049] The ultrasonic knife head 100 has seven side surfaces, among which the clamping surface 1011 is a flat surface, and the other six side surfaces are arc surfaces.

[0050] Referring to Figure 2 , in the embodiment of the present utility model, the clamping surface 1011 includes a first clamping sub-surface 123 provided on the cutter head section 120 and a second clamping sub-surface 111 provided on the cutter body section 110. The width of the first clamping sub-surface 123 gradually decreases from the first end to the second end of the cutter head section 120. The width of the first clamping sub-surface 123 is smaller at the second end, that is, the second end is sharper, which is more conducive to the user performing a shearing operation and improving the shearing efficiency; the width of the first clamping sub-surface 123 is larger at the first end, and the clamping area when cooperating with the ultrasonic knife chuck 300 is larger, increasing the coagulation effect on blood vessels and further reducing intraoperative bleeding. The second clamping sub-surface 111 is close to the tool shank 200, and the clamping force it can provide is limited when cooperating with the ultrasonic knife chuck 300 during actual use. Therefore, the shape of the second clamping sub-surface 111 is not limited herein.

[0051] Referring to Figure 1 and Figure 4 , in the embodiment of the present utility model, the ultrasonic knife head 100 has seven side surfaces. Specifically in this embodiment, the seven side surfaces are the first side surface 101, the second side surface 102, the third side surface 103, the fourth side surface 104, the fifth side surface 105, the sixth side surface 106, and the seventh side surface 107 in sequence. Among them, the first side surface 101 is the clamping surface 1011, the third side surface 103 is the protection surface 1031, the first side surface 101 is a flat surface, and the second side surface 102, the third side surface 103, the fourth side surface 104, the fifth side surface 105, the sixth side surface 106, and the seventh side surface 107 are all arc surfaces. The arc radii of the second side surface 102, the third side surface 103, and the fourth side surface 104 are 35 mm, and the arc radii of the fifth side surface 105 and the sixth side surface 106 are 45 mm, which can enable the user to have a better surgical field of view during operation.

[0052] In one embodiment, one of the side surfaces is an arc surface and is provided on the side of the cutter head section 120 facing the second direction to form a protection surface 1031, and the protection surface 1031 is perpendicular to the clamping surface 1011.

[0053] Combined with Figure 3 and Figure 5, in an embodiment of the present utility model, the side surface of the cutter head section 120 facing the second direction is a protection surface 1031, and the protection surface 1031 is perpendicular to the clamping surface 1011. When the ultrasonic cutter head 100 extends into the periphery of a blood vessel to perform surgical operations on tissues such as mesentery or lymph around the blood vessel, the protection surface 1031 fits against the blood vessel, preventing the cutting edge 108 from contacting the blood vessel, thereby avoiding accidental injury to the blood vessel and improving the safety of surgical operations.

[0054] In one embodiment, the cutter head section 120 is provided with a coagulation surface 121, and the coagulation surface 121 is provided at the end face portion of the second end of the cutter head section 120 and is perpendicular to the axis of the cutter bar 200.

[0055] Refer to Figure 2 , in an embodiment of the present utility model, a coagulation surface 121 is provided at the end of the second end of the cutter head section 120, and the coagulation surface 121 is perpendicular to the axis of the cutter bar 200. When there are symptoms of minor bleeding on the tissue surface or slight bleeding of capillaries during the operation, the user can press the above-mentioned minor bleeding site through the coagulation surface 121, thereby coagulating the bleeding site, reducing bleeding during the operation, and improving the convenience of the user's operation.

[0056] In one embodiment, the cutter head section 120 is provided with a guiding surface 122, and the guiding surface 122 is provided on the side of the second end of the cutter head section 120 facing the second direction and is parallel to the axis of the cutter bar 200.

[0057] Refer to Figure 2 , in an embodiment of the present utility model, a guiding surface 122 is further provided at the second end of the cutter head section 120. The guiding surface 122 is parallel to the axis of the cutter bar 200 and is provided on the side of the second end facing the second direction. The provision of the guiding surface 122 makes the second end of the cutter head section 120 more flattened, that is, the tip part of the entire ultrasonic cutter head 100 is more flat. On the one hand, it is easier to insert into the tissue, on the other hand, the inserted position is more accurate, and on the third hand, it can provide a better surgical field of view for the user, thereby improving the usability of the ultrasonic cutter head 100.

[0058] The present utility model also proposes an ultrasonic scalpel, including the above-mentioned ultrasonic cutter head 100; and

[0059] a cutter bar 200, and the ultrasonic cutter head 100 is provided at the distal end of the cutter bar 200.

Since this ultrasonic scalpel adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated one by one here. Among them, the ultrasonic scalpel head 100 is arranged on the tool rod 200, and the tool rod 200 is used to connect the driving handle of the ultrasonic scalpel. The driving handle drives the ultrasonic scalpel head 100 to vibrate at high frequency through the tool rod 200, so as to realize the functions of cutting and hemostasis. Refer to Figure 5 , the ultrasonic scalpel in this embodiment further includes a tool tube and an ultrasonic scalpel chuck 300. The ultrasonic scalpel chuck 300 is rotatably arranged on the tool rod 200. The tool tube is movably sleeved outside the tool rod 200 and is drivingly connected to the ultrasonic scalpel chuck 300. The tool tube drives the ultrasonic scalpel chuck 300 to rotate, so as to cooperate with the ultrasonic scalpel head 100 to clamp or release the surgical site.
