[0023] The following will specifically describe the preferred embodiments of the present invention with reference to the accompanying drawings. The accompanying drawings form a part of this application and are used together with the embodiments of the present invention to explain the principles of the present invention, rather than to limit the scope of the present invention.

[0024] Embodiment 1:

[0025] The present invention provides an end clamping device, as Figure 1 and Figure 2 shown, including a fixing part 1, a clamping part 2 and a clamping pad 3. The fixing part 1 can be in various shapes, such as claw-shaped, block-shaped, etc. In this embodiment, the fixing part 1 is strip-shaped and has a clamping groove opened at its top. The fixing part 1 is connected to the tool bar 4 of the ultrasonic scalpel and is arranged along the axial direction of the tool bar 4 of the ultrasonic scalpel.

[0026] One side of the clamping part 2 is hinged to the fixing part 1, and a protruding part 5 is formed on the side of the clamping part 2 opposite to the fixing part 1.

[0027] Wherein, the cross-section of the side of the clamping part 2 away from the fixing part 1 is arc-shaped, and the center of the arc-shaped cross-section faces the fixing part 1.

[0028] By setting the cross-section of the side of the clamping part 2 away from the fixing part 1 to be arc-shaped, the bending strength of the clamping part 2 along the length direction can be increased, and the bending deformation of the clamping part 2 during the process of clamping an object can be avoided.

[0029] Wherein, the clamping part 2 can be hinged to the fixing part 1 through a rotating shaft, a rotating pin or a hinge, etc. In this embodiment, the clamping part 2 is hinged to the fixing part 1 through a rotating pin.

[0030] Wherein, the protruding part 5 can be integrally formed with the clamping part 2, or can be connected to the clamping part 2 by means of welding, bonding, screw thread connection, etc. In this embodiment, the protruding part 5 is formed by protruding outward from the side of the clamping part 2 opposite to the fixing part 1 and the protruding part 5 is integrally formed with the clamping part 2.

[0031] The clamping pad 3 is arranged between the clamping part 2 and the fixing part 1 and is detachably connected to the protruding part 5.

[0032] By detachably connecting the clamping pad 3 to the protruding part 5, during the process of clamping an object, the clamping part 2 is rotated, and the clamping part 2 drives the clamping pad 3 to rotate. Under the combined action of the rotating clamping pad 3 and the fixing part 1, the object is clamped until the clamping pad 3 and the fixing part 1 clamp the object to be clamped, realizing the clamping of the object. By setting the clamping pad 3, the friction force on the object to be clamped can be increased, preventing the object to be clamped from falling off during the clamping process; the clamping pad 3 can also prevent the clamping part 2 and the protruding part 5 from directly contacting the object to be clamped, increasing the service life of the clamping part 2 and the object to be clamped.

[0033] If the clamping pad 3 is directly clamped to the clamping part 2, it is necessary to inwardly open an I-shaped groove on the relatively small-sized clamping part 2, then set a corresponding part on the clamping pad 3, and make the clamping pad 3 clamped to the clamping part 2. This method has defects. It is not easy to ensure the precision of opening the I-shaped groove in the clamping part 2, which may cause the clamping pad 3 to fall off from the I-shaped groove after being clamped in the I-shaped groove. Opening the I-shaped groove in the clamping part 2 requires high processing precision and is not easy to process, resulting in an increase in the processing cost of the clamping part 2. In the present invention, by providing a protruding part 5 and connecting the clamping pad 3 to the protruding part 5, the connection between the clamping pad 3 and the clamping part 2 is realized. Since the overall structure of the protruding part 5 is exposed outside the clamping part 2, the processing difficulty is reduced and the processing cost is saved. The clamping pad 3 can be produced by injection molding, its processing precision is easy to control, and the cost is relatively lower than that of machining.

[0034] By detachably connecting the clamping pad 3 to the protruding part 5, when the clamping pad 3 is damaged, a new clamping pad 3 can be replaced.

[0035] Among them, the clamping pad 3 can be connected to the protruding part 5 by screws or can be clamped to the protruding part 5 by a buckle. In this embodiment, the clamping pad 3 is provided with a clamping groove opposite to the protruding part 5, and the clamping pad 3 is clamped to the protruding part 5 through the clamping groove.

[0036] Among them, the material of the clamping pad 3 can be rubber, silica gel, etc. The clamping pad 3 can be produced by injection molding or other methods, and the material and processing method of the clamping pad 3 are not limited to this.

[0037] Among them, after the clamping pad 3 is clamped to the protruding part 5, it can slide relative to the protruding part 5 or can be fixed relative to the protruding part 5. In this embodiment, the clamping pad 3 can slide along the length direction of the clamping part 2.

[0038] By setting the clamping pad 3 to be able to slide along the length direction of the clamping part 2, it is convenient to adjust the fixed position of the clamping pad 3 and is also beneficial to the installation of the clamping pad 3.

[0039] Among them, the clamping groove can penetrate the clamping pad 3, or the clamping groove can be provided locally on the clamping pad 3. In this embodiment, the clamping groove penetrates the clamping pad 3.

[0040] By making the clamping groove penetrate the clamping pad 3, when the clamping pad 3 is clamped to the protruding part 5, the clamping pad 3 can be directly clamped to the protruding part 5 from the side of the protruding part 5 away from the hinge of the clamping part 2, and then the clamping pad 3 is slid so that the clamping pad 3 slides along the length direction of the protruding part 5 until the clamping pad 3 slides to a predetermined position. Setting the clamping groove to penetrate the clamping pad 3 can facilitate the installation of the clamping pad 3 on the protruding part 5.

[0041] Such as Figure 5As shown, the cross-section of the card slot can be stepped or trapezoidal. In this embodiment, the protruding portion 5 is T-shaped. Correspondingly, the cross-section of the card slot is stepped. The large-diameter side of the card slot is farther from the clamping portion 2 than the small-diameter side. The clamping pad 3 can be slidably clamped on the T-shaped protruding portion 5 through the card slot.

[0042] By setting the protruding portion 5 to be T-shaped and the cross-section of the card slot to be stepped, when the clamping pad 3 is clamped on the protruding portion 5 through the card slot, the large-diameter side of the card slot is farther from the clamping portion 2 than the small-diameter side, and the clamping pad 3 is successfully clamped on the protruding portion 5, preventing the clamping pad 3 from falling off the protruding portion 5 in the direction away from the clamping portion 2.

[0043] In this embodiment, the side of the clamping pad 3 facing the fixed portion 1 is provided with anti-slip lines.

[0044] Among them, the anti-slip lines can be arranged in a grid shape, a dot matrix shape, a serrated shape, etc. In this embodiment, the anti-slip lines are arranged in a serrated shape, but the shape of the anti-slip lines is not limited to this.

[0045] Among them, the anti-slip lines can be arranged locally on the side of the clamping pad 3 facing the fixed portion 1, or the entire side of the clamping pad 3 facing the fixed portion 1 can be provided with anti-slip lines, and the area and region of the arrangement of the anti-slip lines are not limited to this.

[0046] By providing anti-slip lines on the side of the clamping pad 3 facing the fixed portion 1, when the clamping pad 3 and the fixed portion 1 act together to clamp an object, it is possible to prevent the clamping pad 3 from sliding relative to the object and avoid slipping when clamping the object.

[0047] In this embodiment, the end clamping device further includes a limiting portion 6a. The limiting portion 6a is connected to the protruding portion 5 and is used to limit the sliding of the clamping pad 3 relative to the protruding portion 5.

[0048] By providing the limiting portion 6a, after the clamping pad 3 is clamped to the protruding portion 5, the limiting portion 6a is connected to the protruding portion 5. The protruding portion 5 is used to limit the sliding of the clamping pad 3 relative to the protruding portion 5, preventing the clamping pad 3 from sliding relative to the protruding portion 5 during the process of clamping an object.

[0049] The limiting portion 6a can be provided on either side of the protruding portion 5. In this embodiment, the limiting portion 6a is provided on the side of the protruding portion 5 away from the hinge of the clamping portion 2.

[0050] Such as Figure 3 and Figure 4 As shown, in one embodiment, the limiting portion 6a is fixedly connected to the side of the protruding portion 5 away from the hinge of the clamping portion 2. The limiting portion 6a can be connected to the clamping portion 2 by means such as bonding and welding. The limiting portion 6a can also be integrally formed with the clamping portion 2.

[0051] By providing a limiting portion 6a on one side of the protruding portion 5 away from the hinge of the clamping portion 2, the limiting portion 6a can limit the movement of the clamping pad 3 to one side. The other side of the clamping pad 3 is provided at the hinge of the clamping portion 2 and the fixing portion 1. Under the combined action of the limiting portion 6a, the fixing portion 1 and the clamping portion 2, the clamping pad 3 is prevented from moving longitudinally along the protruding portion 5. The limiting portion 6a can also prevent the clamping pad 3 from falling off from the side of the protruding portion 5 away from the hinge of the clamping portion 2.

[0052] Furthermore, the end clamping device further includes a fixing pad 7. The fixing pad 7 is disposed opposite to the limiting portion 6a and fixedly connected to the clamping pad 3.

[0053] In this embodiment, the fixing pad 7 and the clamping pad 3 are integrally formed, and the connection manner between the fixing pad 7 and the clamping pad 3 is not limited thereto.

[0054] By providing the fixing pad 7, the limiting portion 6a is prevented from directly contacting the object to be clamped, and the object to be clamped is prevented from being pinched by the limiting portion 6a.

[0055] The present invention also relates to an ultrasonic scalpel system, which includes the above-mentioned end clamping device.

[0056] Embodiment Two:

[0057] The similarities between Embodiment Two and Embodiment One will not be elaborated. The differences between Embodiment Two and Embodiment One are that, as Figure 4 shown, the limiting portion 6b is detachably connected to the protruding portion 5.

[0058] In this embodiment, the protruding portion 5 is provided with a first through hole in a direction perpendicular to the length of the limiting portion 6b. The clamping pad 3 is provided with a second through hole corresponding to the first through hole. The limiting portion 6b is inserted into the first through hole and the second through hole.

[0059] By providing the first through hole and the second through hole and inserting the limiting portion 6b into the first through hole and the second through hole, the fixing of the clamping pad 3 in the longitudinal direction of the protruding portion 5 is achieved. On the basis of combining with the card slot, the fixing of the clamping pad 3 relative to the protruding portion 5 is achieved, preventing the clamping pad 3 from sliding relative to the protruding portion 5 and preventing the clamping pad 3 from falling off from the protruding portion 5.

[0060] Optionally, the limiting portion 6b is in the shape of a stepped shaft. The small diameter section of the limiting portion 6b can slide through the first through hole and the second through hole, and the outer diameter of the large diameter section of the limiting portion 6b is greater than the diameters of the first through hole and the second through hole.

[0061] By setting the limiting portion 6b in the shape of a stepped shaft and passing the small-diameter section of the limiting portion 6b through the first through-hole and the second through-hole, the limiting of the clamping pad 3 relative to the protruding portion 5 is achieved, avoiding the sliding of the clamping pad 3 relative to the protruding portion 5. By setting the diameter of the large-diameter section of the limiting portion 6b to be larger than the diameters of the first through-hole and the second through-hole, it can be avoided that the limiting portion 6b completely penetrates through the first through-hole and cannot be pulled out from the first through-hole.

[0062] Among them, the limiting portion 6b can be threadedly connected to the first through-hole or in interference fit with the first through-hole. In this embodiment, the clamping pad 3 is made of a flexible material, and the small-diameter section of the limiting portion 6b is in interference fit with the first through-hole.

[0063] By making the small-diameter section of the limiting portion 6b in interference fit with the first through-hole of the clamping pad 3, a frictional force is generated between the limiting portion 6b and the inner wall of the first through-hole, avoiding the detachment of the limiting portion 6b from the clamping pad 3 and the protruding portion 5 during the process of clamping an object. By setting the material of the clamping pad 3 to be a flexible material, after the limiting portion 6b is in interference fit with the first through-hole, by applying a certain amount of force, the limiting portion 6b can be pulled out from the first through-hole. When the clamping pad 3 needs to be replaced, the limiting portion 6b is pulled out from the first through-hole, then a new clamping pad 3 is replaced, and the limiting portion 6b is inserted into the first through-hole and the second through-hole. Finally, the limiting portion 6b is fixed to the flexible clamping pad 3 to limit the sliding of the clamping pad 3 relative to the protruding portion 5.

[0064] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
