[0030] The technical solution of the present utility model is described in detail below with reference to specific embodiments.

[0031] Specifically, in a specific embodiment of the present invention, the cutting head structure 5 includes: a cutting head body 501 ; and a sawtooth cutting surface structure 502 provided on the cutting head body 501 .

[0032] Specifically, in a specific embodiment of the present invention, the sawtooth cutting surface structure 502 is provided with a plurality of groups of tooth structures arranged opposite to each other; the notch angles of adjacent tooth structures are 90°; and the tooth height of the tooth structure is 0.018 in.

[0033] Specifically, in a specific embodiment of the present invention, the aperture of the through pipe 401 is 0.072 to 0.076 inches.

[0034] Specifically, in a specific embodiment of the present invention, the aperture of the through pipe 401 is 0.074 in.

[0035] Specifically, in a specific embodiment of the present utility model, the cutter head interface structure 1 is a threaded interface structure.

[0036] Specifically, in a specific embodiment of the present invention, the diameter of the through-hole structure 402 is 0.012 to 0.014 inches.

[0037] Specifically, in a specific embodiment of the present invention, the aperture of the through-hole structure 402 is 0.013 IN.

[0038] Specifically, in a specific embodiment of the present utility model, the blade main body section structure 2, the blade surgical end structure 3, and the cutting blade structure 5 are an integrally formed structure.

[0039] In addition, an embodiment of the present invention provides a short straight ultrasonic aspiration surgical procedure, comprising: a handle; and the above-mentioned short straight ultrasonic aspiration surgical blade structure detachably connected to the handle, which also has the above-mentioned technical effects.

[0040] To be more specific, an ultrasonic scalpel uses the oscillating energy of ultrasound to cut tissue, and can achieve different degrees of cutting effect by adjusting the frequency and energy of ultrasound. An ultrasonic scalpel is a medical device that uses ultrasonic energy for surgical operations. The design of a short straight ultrasonic scalpel facilitates more precise positioning and operation during surgery, thereby improving the accuracy and safety of the surgery, and has a wide range of applications.

[0041] In the prior art, short straight blade heads for ultrasonic surgery generally have a round and smooth contact surface. For some high-density tissues or fibrous tissues, the tissue processing effect is poor and the penetration is insufficient, which prolongs the operation time and increases the area of ​​trauma to the patient. Short straight blade heads for ultrasonic surgery in the prior art have the following disadvantages, namely, most of the existing short straight blade heads have a round and smooth contact surface, which is poor in processing high-density tissues or fibrous tissues; most blade heads do not have a through hole at the front end of the blade head, which may have a high risk of clogging; most surgical blade heads and handles are integrated, and the maintenance cost is high.

[0042] The short straight ultrasonic suction scalpel provided in the embodiment of the present invention has a threaded interface at the front end of the blade head for connecting to the handle, which requires a specific torque tool. The use of a specific torque tool can ensure that the torque on the threaded opening is applied accurately and evenly, while also protecting the threaded opening from damage and extending the service life of the threaded opening of the handle. The middle pipe (middle pipe 401) is hollow and is used for transporting tissue cells for suction. The aperture of the hollow middle pipe is 0.074in, and the aperture of the small through hole (through hole structure 402) that completely passes through the tail is 0.013in. The blade head surface is serrated, which has a stronger force for removing tissue and a better effect.

[0043] Before performing surgery, a specific torque wrench and torque clamp are used to connect the blade head to the handle, which can improve the connection between the handle and the blade head. When the wake-up function is not used, the cooling liquid entering the handle will be completely penetrated by the through hole at the tail of the blade head, with a diameter of 0.013in, and sucked back into the negative pressure drainage tank, so that the liquid will not drip out when not performing surgery. The water circulation on the blade head can minimize the possibility of blockage, while reducing the atomization of the flushing liquid, and providing a clearer field of vision; it can also remove the heat generated by the swing of the blade head, preventing damage to heat-sensitive tissues and damage to the blade head. In the embodiment of the present utility model, the blade head surface is smooth and serrated, with the serrations at 90°. The serrated blade head can achieve better surgical results, aiming to increase cutting ability and can cut certain types of tissue, such as calcified tumors and fibrous tissue. Among them, the 90° notch of the saw teeth helps the tool to enter the material more easily and start cutting, reducing the initial resistance of cutting, and can reduce friction and heat during cutting, extending the service life of the tool, and can improve the stability and accuracy of cutting, making the cutting surface smoother and more precise. The 90° notch of the cutter head saw teeth can also reduce the tool jamming phenomenon during the cutting process, improving work efficiency and safety. In addition, on the one hand, this type of blade has better tissue processing effects on some high-density tissues or fibrous tissues, and on the other hand, it has relatively good penetration, which shortens the operation time and reduces the area of ​​trauma to the patient. Compared with existing similar super-suction short straight blades, the serrated surface can have better tissue processing penetration for some high-density tissues or fibrous tissues, which can relatively reduce the operation time and difficulty. The blade end is also provided with a completely through-hole to reduce the risk of blockage, and the connection with the handle is also a threaded connection. The disposable blade head also reduces the difficulty and cost of maintenance. The use of medical titanium alloy materials makes the instruments light and can reduce damage to blood vessels, muscles, and organs during surgery, reducing the fatigue of doctors. Medical titanium alloy instruments are more suitable for delicate surgical operations, have good corrosion resistance and are non-toxic. The equipment does not rust, the wound is not easy to get infected, and the wound heals quickly.

[0044] In summary, compared with the existing ultrasonic suction blade, the long bend in the middle of the blade involved in the embodiment of the utility model can make it fit the special surgical site better, avoiding the increase of surgical trauma sites, and the through-hole design can collect the liquid that provides cooling for the handle, and the water mist generated during the operation can also be absorbed, making the surgical field of view clearer. The water circulation on the blade can minimize the possibility of blockage, and can also remove the heat generated by the swing of the blade, preventing damage to heat-sensitive tissues and damage to the blade. The removed tissue fragments can be directly attracted into the negative pressure drainage tank, overcoming the disadvantage of blocking the surgical field of view, and has significant technical effects.

[0045] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
