Description

Technical Field

[0001] The present application relates to the technical field of surgical knives, and in particular to a surgical knife with a light source for breast subcutaneous gland resection. Background Art

[0002] Currently, laparoscopically assisted subcutaneous mastectomy (NSM) combined with prosthetic reconstruction is rapidly gaining popularity. Traditionally, many doctors use laparoscopic ultrasonic scalpels, electric scalpels, or electric hooks to free the superficial part of the subcutaneous superficial fascia layer. This process takes about 30 to 90 minutes. If the surgical level is not accurately grasped, it may cause thermal damage to the flap or even ischemic necrosis. In order to solve this problem, some doctors have begun to use cold knife technology, that is, using a scalpel to free the superficial layer of the subcutaneous superficial fascia. This method not only shortens the freeing time, which only takes 15 to 60 minutes, but also because of its high efficiency and little impact on the blood supply of the flap, it has become an effective means to improve surgical safety and efficiency.

[0003] During a cold knife breast enucleation, doctors typically inject a certain amount of epinephrine saline into the pre-mobilized superficial fascia to promote vasoconstriction and reduce bleeding. The doctor then palpates the skin thickness with their left hand while using a scalpel in their right hand to free the superficial layer of the superficial fascia. The free flap must maintain a consistent thickness to achieve a better cosmetic result. However, due to varying surgeons' experience, the thickness of the free flap may vary, leading to bilateral breast asymmetry.

[0004] With the advancement of laparoscopic NSM surgery, the use of light transmission testing to assess intraoperative free flap thickness has become a practical technique. A scalpel with a light installed on the front end has become commercially available. During surgery, the shadowless lamp is turned off and the lights in the operating room are dimmed. The light on the front end of the scalpel is then used to illuminate the free flap. When the free flap is thick, the light transmission is weak; when the free flap is thin, the light transmission is strong. However, because the light source on the front end of the scalpel is relatively concentrated, the light source under the breast skin is unevenly distributed, which can easily lead to different light intensities in different parts of the flap, and thus misjudgment of the flap thickness.

[0031] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0032] The utility model provides Figures 1 to 4 As shown in the figure, a surgical knife with a light source for breast subcutaneous gland resection is intended to solve the disadvantage of existing surgical knives with a light source that the light source is unevenly emitted at different parts.

[0033] This light-emitting surgical knife for subcutaneous breast gland removal primarily comprises a handle 10, a blade 20, and a mounting boss 40. The blade 20 is positioned at one end of the handle 10, and the mounting boss 40 is mounted on the blade 20. During actual use, the mounting boss 40 is used to engage and secure a surgical blade 50 to the blade 20. Medical personnel use the handle 10 to hold the knife in their hand, while the blade 20 is used to emit or guide light, facilitating illumination of the skin flap during surgery.

[0034] Specifically, the blade body 20 has a back end, and a positioning groove 30 is provided on the blade body 20. The positioning groove 30 is set through the blade body 20 in the direction away from the back end. That is to say, in addition to the original opening, the positioning groove 30 also has an opening in the direction away from the back end. The blade edge of the surgical blade 50 protrudes from the blade body 20 through the opening.

[0035] Among them, the bottom and side walls of the positioning groove 30 respectively form a first positioning surface 31 and a second positioning surface 32, the first positioning surface 31 is parallel to the handle portion 10 and the blade portion 20, respectively, and the mounting boss 40 is arranged on the first positioning surface 31 for clamping and fixing the surgical blade 50, the first positioning surface 31 is used to fit with one side of the blade body of the surgical blade 50 to position the surgical blade 50, at this time the surgical blade 50 is parallel to the handle portion 10 and the blade portion 20, respectively; the second positioning surface 32 is used to abut against the back of the surgical blade 50 to position the surgical blade 50, through the gongt action of the mounting boss 40, the first positioning surface 31 and the second positioning surface 32, the surgical blade 50 can be stably fixed at a preset position, which is convenient for medical staff to use.

[0036] Specifically, such as Figures 1 to 4 As shown in FIG, the surgical blade 50 has a through hole that matches the mounting boss 40, allowing the surgical blade 50 to be snap-fitted to the mounting boss 40. Preferably, the spacing between the positioning slot 30 on the blade body 20 facing the handle 10 and the end of the blade body 20 facing away from the handle 10 is 5 cm. The blade back is approximately 0.5 cm thick, and the mounting boss 40 protrudes 2 cm from the blade body 20. This facilitates the mounting boss 40 and positioning slot 30 for mounting and securing a No. 23 universal round blade (5 cm long, 2.9 cm wide). The spacing between the positioning slot 30 and the end of the blade body 20 facing the handle 10 is 8 cm, and this portion is elliptical.

[0037] With the advancement of laparoscopic NSM surgery, the use of light transmission testing to assess intraoperative free flap thickness has become a practical technique. A scalpel with a light installed on the front end has become commercially available. During surgery, the shadowless lamp is turned off and the lights in the operating room are dimmed. The light on the front end of the scalpel is then used to illuminate the free flap. When the free flap is thick, the light transmission is weak; when the free flap is thin, the light transmission is strong. However, because the light source on the front end of the scalpel is relatively concentrated, the light source under the breast skin is unevenly distributed, which can easily lead to different light intensities in different parts of the flap, and thus misjudgment of the flap thickness.

[0038] The present invention uses the entire blade body 20 for emitting light or guiding light, and the light source emitted by the present invention is more uniform compared to the existing scalpels with a lighting lamp at the front end. When used subcutaneously in the breast, the light intensity received by different parts of the skin flap can be more uniform, thereby making it easier to judge the thickness of the skin flap, achieving rapid and accurate resection of the subcutaneous glands of the breast, significantly shortening the operation time, and reducing the risk of ischemic necrosis of the skin flap.

[0039] In some embodiments, as Figure 1 、 Figure 2 and Figure 4 As shown in the figure, the blade body 20 includes a light guide plate 21 and a light emitter 22. A positioning slot 30 is provided on the light guide plate 21. The light emitter 22 is located at the end of the light guide plate 21 facing the handle 10. The light guide plate 21 is used to diffuse the light emitted by the light emitter 22 to the outer surface of the light guide plate 21 for emission. Preferably, the light guide plate 21 is made of the material of existing LED light diffusers, and multiple metal strips can be used as support in the middle to enhance the structural strength of the light guide plate 21.

[0040] In some embodiments, the light guide plate 21 is provided with a plurality of light guide points (not shown), which are evenly distributed on the outer surface of the light guide plate 21. This structure provides uniform light emission on the outer surface of the light guide plate 21, which is more uniform than the light emitted by existing scalpels with front-end lighting. When used subcutaneously on a breast, this allows for more uniform illumination intensity across different parts of the flap, making it easier to determine the flap's thickness, enabling rapid and precise resection of the subcutaneous glands, significantly shortening the surgical time, and reducing the risk of ischemic necrosis of the flap.

[0041] In some embodiments, as Figures 1 to 4 As shown in FIG, the mounting boss 40 is made of the same material as the blade body 20 and is integrally formed with the blade body 20. This reduces production costs and prevents the mounting boss 40 from blocking light emitted by the blade body 20. This allows for more uniform illumination of different areas of the skin flap when used subcutaneously in the breast.

[0042] In some embodiments, the light emitting body 22 is a light emitting diode. Preferably, the light emitting diode adopts the light emitting diode structure in the existing LED lamp beads.

[0043] In some embodiments, as Figure 2 and Figure 4 As shown in FIG, the handle 10 includes a barrel 11, which contains a battery compartment for accommodating batteries. Preferably, the barrel 11 is made of stainless steel and has a non-slip texture on the outer surface to prevent the handle 10 from slipping when grasping. The barrel 11 is 12 cm long and has an inner diameter of 1 cm. It can be powered by two AAA batteries or rechargeable lithium batteries.

[0044] The switch 12 is provided at one end of the barrel 11 away from the blade 20. The switch 12 is used to control the on / off of the battery in the battery compartment and the light emitting body 22. Preferably, the switch 12 is a push-type switch 12. Pressing once turns on the light emitting body 22, and pressing again turns off the light emitting body 22.

[0045] In some embodiments, as Figure 2 and Figure 4 As shown in FIG, the blade body 20 is threadedly connected to the handle 10, and the blade body 20 can be connected to the handle 10 by rotation.

[0046] In some embodiments, as Figure 1 、 Figure 2 and Figure 4 As shown in the figure, the shape of the blade body 20 is arc-shaped, and the end of the blade body 20 away from the handle 10 is inclined in the direction away from the back of the blade, and the positioning groove 30 is provided at the end of the blade body 20 away from the handle 10 and the back of the blade for easy use.

[0047] In some embodiments, as Figure 2 and Figure 4 As shown in FIG, the thickness of the blade portion 20 gradually decreases in the direction away from the blade back end.

[0048] Specifically, this structure allows the light emitted by the light emitting body 22 to be concentrated in the direction of the surgical blade 50, which is beneficial to the skin flap light transmission test.

[0049] In some embodiments, as Figure 1 、 Figure 2 and Figure 4 As shown in FIG, the outer diameter of the blade body 20 gradually increases in the direction away from the handle 10, which is convenient for use.

[0050] In summary, a surgical knife with a light source for subcutaneous gland excision of the breast is provided, comprising a handle portion, a blade portion, and a mounting boss connected in sequence, the handle portion being used for hand-holding, the blade portion being used for emitting light or guiding light, the mounting boss being used for clamping and fixing a surgical blade, the blade portion having a back end, the blade portion being provided with a positioning groove extending through the blade portion in a direction away from the back end, the bottom and side walls of the positioning groove being used for positioning the surgical blade, respectively, and the cutting edge of the surgical blade protruding outward from the blade portion. By utilizing the entire blade portion for emitting light or guiding light, the present invention emits a more uniform light source than existing surgical knives with a front-end lighting lamp. When used subcutaneously on the breast, the light intensity received by different parts of the skin flap is more uniform, thereby making it easier to judge the thickness of the skin flap, thereby achieving rapid and accurate resection of the subcutaneous glands of the breast, significantly shortening the operation time, and reducing the risk of ischemic necrosis of the skin flap.

[0051] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
