Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, and more particularly to a dissector for surgical use. Background Art
[0002] Breast augmentation surgery (also known as mammoplasty) is a plastic surgery that increases breast size and improves breast shape by implanting breast implants such as silicone or saline fillers. In breast augmentation surgery, plastic surgeons generally separate the pectoralis major muscle from the ribs with their fingers to implant the implant under the pectoralis major muscle, and this process is called pectoralis major muscle dissection. The surgeon creates a space between the pectoralis major muscle and the ribs through pectoralis major muscle dissection for placing the implant. Some parts of the pectoralis major muscle are firmly connected to the ribs. When these parts are far from the surgical incision, due to the softness of the fingertips, the dissection ability is insufficient, resulting in the inability to fully separate the pectoralis major muscle from the ribs. For this reason, plastic surgeons hope to use a dissector for dissection.
[0003] Existing dissectors for surgical use are mostly handheld or held-type, with blades or sharp heads. When using such dissectors for pectoralis major muscle dissection, due to the poor finger perception of force, if a little too much force is applied, it is very easy to pierce through the muscle insertion point, resulting in the dissection exceeding the expected range and unable to achieve accurate dissection.
[0004] Therefore, a new type of dissector is needed, which can enhance the dissection force and / or improve the dissection accuracy. Summary of the Utility Model
[0005] The purpose of the utility model is to overcome at least one of the above problems in the prior art.
[0006] According to one aspect of the utility model, there is provided a dissector for surgical use, wherein the dissector comprises: a finger sleeve portion; and a dissection portion disposed at the distal end of the finger sleeve portion, wherein the exposed surface of the dissection portion is a hard blunt surface, and the dissection portion is flat, and the shape of the outer edge of the maximum cross-section of the dissection portion in the height direction is selected from one of the following groups: (a) at least a part of a semi-circle; (b) at least a part of a truncated semi-circle; (c) at least a part of a semi-ellipse; (d) at least a part of a truncated semi-ellipse; and (e) at least a part of a triangle with a rounded head.
[0007] Preferably, the outer edge of the maximum cross-section of the dissection portion in the height direction has two intersection points with the finger sleeve portion, and the straight-line distance between the two intersection points is less than the outer diameter of the proximal end face of the finger sleeve portion in the same direction.
[0008] Preferably, the height of the dissection portion extending away from the finger sleeve portion from the intersection point is in the range of 3 mm - 5 mm.
[0009] Preferably, the finger sleeve part is configured such that when it is put on the operator's finger, the proximal end of the finger sleeve part approaches the distal interphalangeal joint of the finger.
[0010] Preferably, the finger sleeve part includes a rotating body, the rotating body includes a first rotating part, the cross-section of the first rotating part is a circular ring, and the inner diameter of the circular ring cross-section closer to the distal end of the finger sleeve part is smaller.

[0034] In the present application, if there is no special instruction, all the embodiments and preferred embodiments mentioned herein can be combined with each other to form a new technical solution. In the present application, if there is no special instruction, all the technical features and preferred features mentioned herein can be combined with each other to form a new technical solution.
[0035] The finger-shaped dissector for breast augmentation surgery provided according to an embodiment of the present application will be described in detail below with reference to the drawings.
[0036] Figure 1 and Figure 2 show a front view schematic diagram and a top view schematic diagram of a finger-shaped dissector 1 according to an embodiment of the present invention. As Figure 1 and Figure 2 shown, the finger-shaped dissector 1 may include a finger sleeve part 12 and a peeling part 14. The finger sleeve part 12 and the peeling part 14 may be made of a hard material. The proximal end of the finger sleeve part 12 has an opening for being sleeved on the distal phalanx of a finger (for example, the index finger or the middle finger). The peeling part 14 is arranged at the distal end of the finger sleeve part 12. During operation, the operator controls the finger-shaped dissector 1 to perform muscle peeling by bending the finger.
[0037] In some embodiments, the finger sleeve portion 12 may include a hollow rotating body with a circular cross-section, and the inner diameter of the circular cross-section is smaller closer to the distal end. For example, the rotating body may be a hollow hemisphere, or a hollow spherical segment (a spherical segment is a part of a hemisphere), or a hollow and truncated hemisphere or spherical segment. The rotating body may also be a hollow semi-ellipsoid, or a hollow ellipsoidal segment (an ellipsoidal segment is a part of a semi-ellipsoid), or a hollow and truncated semi-ellipsoid or ellipsoidal segment. The rotating body may also be a hollow frustum of a cone. In Figure 1 and Figure 2 In the illustrated embodiment, the rotating body is a truncated semi-ellipsoid.
[0038] In other embodiments, the rotating body may include any one of the above rotating bodies as the first rotating portion, and a second rotating portion located at the proximal end of the first rotating portion, where the second rotating portion may be a cylinder.
[0039] The inner diameter of the proximal end of the finger sleeve portion 12 should be large enough to allow a finger to be inserted into the finger sleeve portion 12. However, if the inner diameter of the proximal end of the finger sleeve portion 12 is too large, it is likely to cause the finger sleeve type dissector to fall off the finger. Preferably, the inner diameter of the proximal end of the finger sleeve portion 12 may be in the range of 1 cm to 2 cm. It should be understood that a series of finger sleeve portions 12 with different inner diameters may be provided to be suitable for fingers of different thicknesses.
[0040] The height of the finger sleeve portion 12 should be long enough so that the finger sleeve type dissector is not easily detached from the finger. However, if the height of the finger sleeve portion 12 is too long, it will hinder finger bending and affect operation. The height of the finger sleeve portion 12 may refer to the length of the distal phalanx of the finger. Preferably, the height of the finger sleeve portion 12 may be configured such that when it is put on the operator's finger, the proximal end of the finger sleeve portion approaches the distal interphalangeal joint of the finger, so that the operator can control the finger sleeve type dissector 1 by bending the distal interphalangeal joint of the finger. In some embodiments, the height of the finger sleeve portion 12 may be in the range of 1 cm to 3 cm. During the actual use of the finger sleeve type dissector 1, after the finger sleeve portion 12 is put on the distal phalanx of the finger, a disposable medical silicone finger sleeve may be put on the outside of the finger sleeve type dissector 1 to more firmly fix the finger sleeve type dissector 1 on the finger. If the height of the finger sleeve portion 12 is too short relative to the operator's finger distal phalanx, this method can also be used to prevent the dissector from falling off.
[0041] To increase the friction between the finger sleeve portion 12 and the finger, an anti-slip structure (not shown) may be provided on the inner wall of the finger sleeve portion 12, so that the finger sleeve type dissector 1 fits more closely to the finger surface, thereby improving stability. In some embodiments, grooves or protrusions may be provided on the inner wall of the finger sleeve portion 12. In other embodiments, a rubber or silicone layer with a relatively high coefficient of friction may be provided on the inner wall of the finger sleeve portion 12.
[0042] The peeling part 14 is arranged at the distal end of the finger sleeve part 12. The exposed surface of the peeling part 14 can be a hard blunt surface. Compared with the soft fingertip, setting the exposed surface of the peeling part 14 as a hard blunt surface can enhance the peeling force.
[0043] The peeling part 14 is flat, and the shape of the outer edge of the maximum cross-section of the peeling part 14 in the height direction (or the front surface of the peeling part 14) can be changed to suit the peeling needs of different surgeries. In Figure 1 and Figure 2 In the illustrated embodiment, the shape of the outer edge of the front surface of the peeling part 14 is at least a part of a semi-ellipse. Figure 3A and Figure 3B Fig. shows a perspective view of a finger sleeve type dissector with a peeling part of other shapes. In Figure 3A In the illustrated embodiment, the shape of the outer edge of the front surface of the peeling part 14 is at least a part of a truncated semi-circle; in Figure 3B In the illustrated embodiment, the shape of the outer edge of the front surface of the peeling part 14 is at least a part of a triangle with a rounded head. In other embodiments, the shape of the outer edge of the front surface of the peeling part 14 can also be at least a part of a truncated semi-ellipse, at least a part of a semi-circle or other shapes suitable for muscle peeling.
[0044] The outer edge of the maximum cross-section of the peeling part 14 in the height direction (or the front surface of the peeling part 14) has two intersection points with the finger sleeve part, and the straight-line distance between these two intersection points is less than the outer diameter of the proximal end face of the finger sleeve part 12 in the same direction. In some embodiments, the finger sleeve part 12 and the peeling part 14 can be integrally formed, while in other embodiments, the finger sleeve part 12 and the peeling part 14 can be independent components. In some embodiments, the peeling part 14 can be detachable, so that different-shaped peeling parts 14 can be replaced as needed. In some embodiments, the peeling part 14 can be connected to the finger sleeve part 12 by snap connection, while in other embodiments, the peeling part 14 can be connected to the finger sleeve part 12 by bolt connection.
[0045] When the height of the peeling part 14 extending away from the finger sleeve part 12 from the intersection point is too long, the stability of the dissector is poor, and when the height of the peeling part 14 is too short, the peeling effect is poor. Preferably, the height of the peeling part 14 extending away from the finger sleeve part 12 from the intersection point is in the range of 3 mm - 5 mm. Setting the extension length of the peeling part of the finger sleeve type dissector in the range of 3 mm - 5 mm can increase the operation stability.
[0046] Figure 4A and Figure 4B Fig. shows a perspective schematic diagram of a finger sleeve type dissector 1 with other shapes. In Figure 4A and4B In the illustrated embodiment, the top surface of the peeling portion 14 is a part of an ellipsoidal surface, and the front surface of the peeling portion 14 is a part of a semi-ellipse. The transition between the top surface and the front surface of the peeling portion 14 can be achieved by filleting or other edge-rounding methods to make the exposed surface of the peeling portion 14 a blunt surface. The finger sleeve portion 12 is at least a part of a semi-ellipsoid, and the transition between the finger sleeve portion 12 and the peeling portion 14 is achieved by filleting or other edge-rounding methods. Compared with Figure 4A the illustrated embodiment, Figure 4B the peeling portion 14 in the illustrated embodiment has a relatively thin thickness. In other embodiments, the top surface of the peeling portion 14 can be a part of a cylindrical surface.
[0047] The materials of the finger sleeve portion 12 and the peeling portion 14 are preferably reusable, so they are preferably sterilizable. In some embodiments, the finger sleeve portion 12 and the peeling portion 14 can be made of the same material, while in other embodiments, the finger sleeve portion 12 and the peeling portion 14 can be made of different materials. In some embodiments, the finger sleeve portion 12 and the peeling portion 14 can be made of stainless steel. In other embodiments, the finger sleeve portion 12 and the peeling portion 14 can be made of plastic.
[0048] Figure 5 Fig. shows a front view schematic diagram of a finger sleeve type dissector 1 according to another embodiment of the present invention. As Figure 5 shown, the finger sleeve type dissector 1 may further include an elastic finger sleeve extension portion 16. The elastic finger sleeve extension portion 16 is a deformable elastic hollow structure, and its distal end is connected to the proximal end of the finger sleeve portion 14, and is used to be sleeved outside the finger, so that the finger sleeve type dissector 1 can be more firmly fixed on the finger and is not easily detached. In some embodiments, the elastic finger sleeve extension portion 16 can be made of silicone or rubber. In some embodiments, the elastic finger sleeve extension portion 16 can be connected to the finger sleeve portion 12 by using an adhesive.
[0049] It should be understood that although the present disclosure mainly describes the finger sleeve type dissector for breast augmentation surgery, such a finger sleeve type dissector can also be applicable to other surgical procedures that require muscle dissection without departing from the scope of the present disclosure.
[0050] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
