Description

Light source breast operation cavity support bracket Technical Field The invention belongs to the technical field of medical instruments, and particularly relates to a light source breast operation cavity support bracket. Background In breast surgery, particularly in breast cancer excision, it is often necessary to make an arcuate incision about 5cm long along the fold of the armpit skin, then to separate the tissue and create a satisfactory cavity for the surgical procedure, and to place a prosthesis after excision of the entire breast. Because of the smaller surgical incision, it is desirable to construct an area of about 15cm within the incisionA larger cutting range of 20cm to form a cavity structure with a small mouth and a large bottom. This can lead to problems of exposure of the surgical field and difficulty in adequate irradiation of the bottom of the cavity with light, and narrow surgical space. To solve this problem, a special retractor has been developed by practitioners in the art, and related prior art, such as a special retractor for mastectomy surgery with a nipple areola complex disclosed in chinese patent CN213217324U, includes a handle portion, a curved portion and a supporting portion, the supporting portion is an arc-shaped curved surface and integrates a light source, and the curved portion is provided with an aspirator interface. The assistant manually holds the handle to pull up to lift the breast tissue and illuminate the operative field with the light source, but when the retractor is used to maintain the cavity in the breast, the assistant is required to continuously apply a pulling force, which easily causes fatigue of the assistant, and an unstable pulling force affects the accuracy of the operation. In addition, the single draw hook mainly provides upward lifting force for the mammary gland through the strip-shaped outer wall of the draw hook, so that uniform and stable multidimensional tension is difficult to form in the mammary gland, and the stability of the operation space is influenced. Disclosure of Invention In order to overcome the problems in the prior art, there is a need for a breast lumen surgical supporting device that can be deployed from a small incision into an operation area and maintain a stable cavity, so as to reduce the continuous dependence of breast lumen maintenance on manpower, thereby improving the surgical efficiency and the operation safety. The invention adopts the following technical scheme: A light source breast surgery cavity support bracket comprises an inner cavity support plate, wherein the inner cavity support plate is composed of a plurality of sliding sleeved arc structures and can extend or retract along the length direction, the inner cavity support plate is provided with a convex dome support surface and a concave light source surface, the dome support surface is attached to and supports the top end of a breast surgery cavity in an extending state, the sliding sleeved arc structures allow an instrument to pass through a small incision in a contracting state to reach a target position and extend, and the arc support surface formed on the outer wall of the arc support structure is automatically attached to the cavity dome to provide upward mechanical supporting force from the inside. The illumination module comprises a plurality of light-emitting units arranged on the light source surface, wherein the light-emitting units irradiate towards the bottom of the operation cavity in an extending state, the light-emitting units are integrated on the outer wall of the arc-shaped structure towards the inside of the cavity, and when the inner cavity supporting plate extends, the light source scatters and illuminates from the periphery of the top of the cavity to the bottom to form a surrounding light path. At least two arc support bars are symmetrically and rotatably arranged on the side wall of one of the arc structures of the inner cavity support plate, when the support bracket is in an extending state, the arc support bars are outwards opened to provide auxiliary support points at the bottom or the side wall of the operation cavity, and when the inner cavity support plate is retracted, the arc support bars are extruded by the adjacent outer arc structures to rotate oppositely and are attached to the outer wall of the arc structure connected with the inner cavity support plate. The connecting structures are arranged at the proximal ends of the arc-shaped structures, which deviate from the operation cavity, and are used for controlling the expansion and contraction of the arc-shaped structures. Further, the arc-shaped structure comprises at least one node sleeve, the arc-shaped supporting strips are rotatably connected to the outer wall of the node sleeve, an elastic piece is arranged between the arc-shaped supporting strips and the outer wall of the node sleeve, and the arc-shaped supporting strips are driven by the elastic piece to extend outward
