[0031] The technical solution of the present invention is described in detail below with reference to specific embodiments:
[0032] Specifically, in a specific embodiment of the present utility model, the cutter head interface structure 1 is a threaded interface structure.
[0033] Specifically, in a specific embodiment of the present invention, the bending angle of the bending segment structure 3 is 8 to 12°.
[0034] Specifically, in a specific embodiment of the present invention, the bending angle of the bending segment structure 3 is 11°.
[0035] Specifically, in a specific embodiment of the present invention, it also includes: a bone scraper knurling structure 7 provided on the bone scraper surface structure 6, the angle between the tooth surface normal of the bone scraper knurling structure 7 and the surgical end structure 4 of the blade is 110°; the tooth end surface width of the bone scraper knurling structure 7 is 0.05.
[0036] Specifically, in a specific embodiment of the present invention, the bone scraper knurling structure is specifically: knurled teeth are provided on the bone scraper knurling structure 7; the tooth height of the knurled teeth is 0.008; the tooth pitch of the knurled teeth is 0.015; and the tooth valley angle of adjacent knurled teeth is 90°.
[0037] Specifically, in a specific embodiment of the present invention, the diameter of the through-hole structure 5 is 0.012 to 0.014 inches.
[0038] Specifically, in a specific embodiment of the present invention, further, in a preferred embodiment of the present invention, the aperture of the through-hole structure 5 is 0.013 in.
[0039] Specifically, in a specific embodiment of the present utility model, the handle end blade structure 2, the bending section structure 3, the blade surgical end structure 4, and the through-hole structure 5 are an integrally formed structure.
[0040] In addition, an embodiment of the present invention further provides an ultrasonic suction scalpel bone scraper, comprising: a handle; and the ultrasonic suction scalpel bone scraper head structure described above, detachably connected to the handle, which also has the above-mentioned technical effects. It should be noted that in the embodiment of the present invention, "in" means "inch", and 1 in = 2.54 cm.
[0041] More specifically, an ultrasonic bone scraper is a medical device that uses ultrasound technology to perform bone scraping, a common surgical technique used to treat orthopedic conditions such as fractures, osteomyelitis, and myeloproliferation. Traditional bone scraping requires the surgeon to hold the tool in hand, which can be easily affected by hand tremors and other factors, resulting in inaccurate scraping.
[0042] The ultrasonic suction bone scraper scalpel in the prior art has the following disadvantages, namely, the long straight blade head in the prior art has a small bend at the knurled teeth, which cannot fully fit the surgical site for special surgical surfaces, easily expanding the wound area of the patient's surgical site and increasing the patient's postoperative pain, and the existing bone scraper has a high risk of clogging and high maintenance costs. Based on this, the scheme involved in the embodiment of the utility model improves the structure of the bone scraper in the prior art. The improved ultrasonic suction scalpel bone scraper head structure mainly includes the following important technical features: a threaded interface 1 connected to the handle; a bending section structure 2; a bone scraping surface 3; a suction port 4; and a completely through-hole 5. Specifically, the front end of the blade head is a threaded interface, and a specific torque tool is required to connect it to the handle. There is a bending section structure at the front, and the bending angle is preferably 11°. The middle pipe is hollow for transporting the attracted tissue cells, and the small through-hole at the tail is completely penetrated, and the specific aperture is 0.013in.
[0043] In an embodiment of the present invention, the middle part of the blade head is bent 11°, and the front end of the blade head is provided with knurled teeth on the bent part to provide more operating space, thereby improving the bone removal efficiency. The knurled teeth or bevel teeth are provided on the bent part to better grind or cut the bone tissue. A completely through-hole is added to the tail, which is connected to the handle through a specific torque tool, which has better sealing and is more convenient for disposable use.
[0044] The long curve allows for better fit and increased surgical coverage for specialized surgical sites. In this utility model, the through-hole absorbs water mist generated during operation, enhancing the surgical field of view. It also allows for automatic recovery of the liquid used to cool the handle, preventing fluid collection before surgery begins. Furthermore, water circulation on the blade minimizes the possibility of blockage and removes heat generated by blade swing, preventing damage to heat-sensitive tissues and the blade itself. The central curve and knurled blade curve design provide a more precise fit for specialized surgical sites, minimizing the area of invasive surgery.
[0045] Before the operation, use a specific torque wrench and torque clamp to connect the blade head to the handle, which can make the connection between the handle and the blade head better. When the wake-up function is not used, the cooling liquid entering the handle will be sucked back into the negative pressure drainage tank by the through hole that completely penetrates the tail of the blade head, and the liquid will not drip out when the operation is not performed. The water circulation on the blade head can minimize the possibility of blockage, while reducing the atomization of the flushing liquid and making the field of vision clearer; 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.
[0046] In summary, compared with the existing similar super-absorbent bone scraper heads, 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.
[0047] 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.
