[0001] The utility model relates to the technical field of medical devices, and more specifically, to an ultrasonic suction surgical knife head structure. In addition, the utility model also relates to an ultrasonic suction surgical knife. Background Art

[0002] Ultrasonic aspiration scalpels are surgical instruments that use high-energy ultrasonic vibrations to pulverize tissue, emulsify it with an irrigating fluid, and then remove tumors and other diseased tissues through negative pressure suction. They are widely used due to their advantages, including minimal damage to the surgical site or surrounding tissue, minimal intraoperative bleeding, clear surgical field of view, low surgical risk, and high safety. As the primary functional component of ultrasonic aspiration scalpels, the ultrasonic aspiration scalpel head structure is particularly important.

[0003] However, existing ultrasonic suction surgical blade structures have the following problems: excessive tissue suction can easily lead to blockage, maintenance and repair are difficult and costly, and the blade does not fit the specific surgical surface, which can easily increase the site of surgical trauma.

[0004] Therefore, how to provide an ultrasonic suction surgical blade structure that can reduce the risk of blockage of the ultrasonic suction surgical blade structure, fit the specific surgical surface, and reduce maintenance costs has become a technical problem that needs to be urgently solved by technical personnel in this field. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an ultrasonic suction surgical blade head structure, which can reduce the risk of blockage of the ultrasonic suction surgical blade head structure, fit the specific surgical surface, and reduce maintenance costs.

[0006] The technical solutions provided by this utility model are as follows:

[0007] The utility model provides an ultrasonic suction surgical blade structure, compared with the existing technology,

[0008] The invention comprises: a hollow cutter head body; a handle connecting portion provided at one end of the hollow cutter head body; a through pipe provided in the hollow cutter head body; a drainage hole structure provided on the hollow cutter head body, the drainage hole structure intersecting the hollow cutter head body at right angles, and the drainage hole structure communicating with the through pipe;

[0009] Among them, the hollow cutter head body includes: a rear end of the hollow cutter head; a hollow cutter head curved portion integrally formed with the rear end of the hollow cutter head; a front end of the hollow cutter head integrally formed with the curved portion of the hollow cutter head; one end of the through pipe located at the rear end of the hollow cutter head is a vacuum suction outlet; one end of the through pipe located at the front end of the hollow cutter head is a vacuum suction inlet; the drainage hole structure is located at the front end of the hollow cutter head.

[0010] Furthermore, in a preferred embodiment of the present invention, the handle connecting portion includes: a handle connecting body provided at the rear end of the hollow blade head; and a handle connecting threaded structure provided at the rear end of the handle connecting body.

[0011] Furthermore, in a preferred embodiment of the present invention, the bending angle of the curved portion of the hollow cutter head is in the range of 15 to 25 degrees.

[0012] Furthermore, the aperture range of the through pipe is 0.07 to 0.08 in.

[0013] Furthermore, in a preferred embodiment of the present invention, the pore size of the drainage pore structure ranges from 0.01 to 0.02 in.

[0014] Furthermore, the hollow cutter head body is made of titanium alloy.

[0015] Furthermore, in a preferred embodiment of the present invention, a protective coating is provided on the hollow inner wall of the hollow cutter head body.

[0016] Furthermore, the length of the rear end of the hollow cutter head ranges from 2 to 2.5 inches.

[0017] Furthermore, the aperture of the front end of the hollow cutter head gradually decreases starting from the curved portion of the hollow cutter head.

[0018] The utility model also provides an ultrasonic suction surgical knife solution, which is characterized by comprising: an ultrasonic suction surgical knife handle; and an ultrasonic suction surgical knife head structure connected to the ultrasonic suction surgical knife handle.

[0019] The ultrasonic suction surgical blade structure provided by the utility model is different from the prior art.

[0020] The invention comprises: a hollow cutter head body; a handle connecting portion provided at one end of the hollow cutter head body; a through pipe provided in the hollow cutter head body; a drainage hole structure provided on the hollow cutter head body, the drainage hole structure intersecting the hollow cutter head body at right angles, and the drainage hole structure communicating with the through pipe;

[0030] Please Figures 1 to 2 As shown, the ultrasonic suction surgical blade structure provided by the embodiment of the present invention includes: a hollow blade body; a handle connection portion 4 provided at one end of the hollow blade body; a through pipe provided in the hollow blade body; a drainage hole structure 6 provided on the hollow blade body, the drainage hole structure 6 intersecting the hollow blade body at right angles, and the drainage hole structure 6 communicating with the through pipe;

[0031] Among them, the hollow cutter head main body includes: a hollow cutter head rear end 1; a hollow cutter head curved portion 2 integrally formed with the hollow cutter head rear end 1; a hollow cutter head front end 3 integrally formed with the hollow cutter head curved portion 2; the through pipe is located at one end of the hollow cutter head rear end 1 as a vacuum suction outlet 501; the through pipe is located at one end of the hollow cutter head front end 3 as a vacuum suction inlet 502; the drainage hole structure 6 is located at the front end 3 of the hollow cutter head.

[0032] Before surgery, the ultrasonic suction surgical blade structure provided by the present invention is connected to the handle through the handle connection portion. The special long curved structure of the hollow blade body can better fit the special surgical site and increase the surgical area. When the blade is cooled with coolant, the coolant is sucked back into the negative pressure drainage tank of the handle by the drainage hole structure 6 that completely penetrates the front end 3 of the hollow blade, and the liquid will not drip out when the surgery is not underway. The coolant forms a water circulation on the blade through the drainage hole structure 6, which minimizes the possibility of blockage and prevents the coolant from atomizing, making the surgical field clearer. The water circulation can also remove the heat generated by the swing of the blade, preventing damage to heat-sensitive tissues and damage to the blade.

[0033] Specifically, the handle connection portion 4 includes: a handle connection body provided at the rear end 1 of the hollow blade head; and a handle connection thread structure 7 provided at the rear end of the handle connection body.

[0034] It should be noted that in the embodiment of the present invention, the handle connecting part 4 is connected to the handle through a specific torque tool, and the handle connecting thread structure 7 is an internal thread so that it can fit tightly with a handle with a corresponding external thread. Compared with the existing technology, it has better sealing and is more convenient to use at one time.

[0035] Specifically, in the embodiment of the present invention, the bending angle of the hollow cutter head bending portion 2 is in the range of 15 to 25 degrees.

[0036] It should be noted that in the embodiment of the present invention, the bending angle of the hollow blade bending portion 2 is specifically 19 to 21 degrees. The hollow blade bending portion 2 helps the hollow blade body to form a special long curved structure, which can better fit the special surgical site and increase the surgical area.

[0037] It should be noted that, in the embodiments of the present invention, “in” means “inch”, and 1 in = 2.54 cm.

[0038] More specifically, in an embodiment of the present invention, it further includes: a silver ion antibacterial coating structure covering the periphery of the hollow blade body to form a long-lasting antibacterial layer.

[0039] Specifically, in the embodiment of the present invention, the aperture range of the through pipe is 0.07 to 0.08 inches.

[0040] It should be noted that, in the embodiment of the present utility model, the aperture of the vacuum suction outlet 501 is specifically 0.078in, and the hollow structure of the hollow cutter head body is used for transporting the sucked tissue cells.

[0041] Specifically, in the embodiment of the present invention, the pore size of the drainage pore structure 6 is in the range of 0.01 to 0.02 in.

[0042] Among them, the pore diameter of the drainage pore structure 6 is specifically 0.013in. The drainage pore structure 6 can not only absorb the water mist generated during work, making the surgical field of view clearer; it can also recycle the handle coolant to avoid the restriction of body fluid collection before the operation begins. In the embodiment of the present utility model, the drainage pore structure 6 forms a water flow circulation at the front end 3 of the hollow blade, which reduces the possibility of blockage, takes away the heat generated by the swing of the blade, and prevents damage to heat-sensitive tissues and damage to the blade.

[0043] Specifically, in an embodiment of the present invention, the hollow cutter head body is made of titanium alloy.

[0044] It should be noted that, in the embodiment of the present invention, the titanium alloy used as the main material of the hollow cutter head has corrosion resistance and high strength to ensure stability and durability under high-frequency ultrasonic vibration.

[0045] Specifically, in an embodiment of the present invention, a protective coating is provided on the hollow inner wall of the hollow cutter head body.

[0046] Thus, the coating provides the functions of reducing friction and preventing tissue adhesion, thereby preventing the blade from being blocked and affecting the surgical process.

[0047] Specifically, in the embodiment of the present invention, the length of the rear end 1 of the hollow cutter head is in the range of 2 to 2.5 inches.

[0048] It should be noted that, in the embodiment of the present invention, the length of the hollow cutter head rear end 1 is specifically 2.255 inches, and the hollow cutter head curved portion 2 integrally formed with the hollow cutter head rear end 1 is immediately following the hollow cutter head rear end 1 .

[0049] Specifically, in the embodiment of the present invention, the aperture of the front end 3 of the hollow cutter head gradually decreases starting from the curved portion 2 of the hollow cutter head.

[0050] More specifically, in an embodiment of the present utility model, another feasible implementation scheme is that the drainage hole structure 6 includes a first drainage structure layer and a second drainage structure layer connected to the vacuum suction inlet 502; the first drainage structure layer close to the vacuum suction inlet 502 is provided with a first through-hole structure; the second drainage structure layer relatively far away from the vacuum suction inlet 502 is provided with a second through-hole structure, and the number and pore size of the second through-hole structure are smaller than those of the first through-hole structure to maintain a certain fluid pressure gradient.

[0051] In addition, the utility model also provides a technical solution for an ultrasonic suction scalpel, including: the ultrasonic suction scalpel handle as described above; and an ultrasonic suction scalpel head structure connected to the ultrasonic suction scalpel handle, which also has the above technical effects.

[0052] To elaborate more specifically, Figure 2 The ultrasonic suction scalpel in the prior art is the main functional component of the ultrasonic suction scalpel and is particularly important for the ultrasonic suction scalpel. However, the existing ultrasonic suction scalpel head structure is prone to blockage due to excessive tissue suction, and there are problems such as difficulty and high cost in maintenance and repair, as well as the problem of not fitting the specific surgical surface, resulting in an increase in the surgical trauma site. For this reason, the technical solution involved in the utility model is based on the existing technical problems and proposes improvements. The special long curved structure of the hollow blade head body can make the special surgical site better fitted, increase the surgical area, and when the coolant is used to cool the blade head, the coolant will be cooled by the hollow blade head. The drainage hole structure that completely penetrates the front end absorbs the liquid back into the negative pressure drainage tank of the handle, so that the liquid will not drip out when the operation is not performed. The coolant forms a water circulation on the blade through the drainage hole structure, which minimizes the possibility of blockage and prevents the coolant from atomizing, making the surgical field of view clearer. In addition, the water circulation can also take away the heat generated by the swing of the blade, preventing damage to heat-sensitive tissues and damage to the blade. It can be seen that compared with the ultrasonic suction scalpel in the prior art, the advantages of the technical solution involved in the utility model include: avoiding the increase of surgical trauma sites; clearer surgical field of view; reducing maintenance costs, and having significant technical effects.

[0053] 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.
