Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an arc-shaped knife handle for laparoscopic breast surgery. Background Art

[0002] At present, in single-port laparoscopic breast surgery, the incision is usually deep into the superficial layer of the breast gland through a single-port incision, and the superficial breast flap and the deep gland are separated layer by layer to complete the flap separation as soon as possible. If the breast flap is not properly freed, it is easy to cause flap necrosis, fluid accumulation, wound infection, etc., resulting in poor recovery.

[0003] In the prior art, the flap release in single-port laparoscopic breast surgery is usually performed using a laparoscopic electrocoagulation hook, which has the following defects: 1. Excessive power of the electric hook can cause a very high temperature in the local incision, which can easily scald the flap during the operation, leading to skin burns or even skin burns. 2. High temperature will increase local tissue exudation, and the exudate protein will block the subcutaneous vascular network after coagulation, affecting the blood supply of the flap, causing fat liquefaction and postoperative seroma. 3. The operation requires extremely high technical proficiency and precision, resulting in cumbersome surgical steps and a long time. In addition, the effectiveness and stability of the electric hook are also affected by many factors, such as temperature control, current intensity, etc., which require continuous monitoring and adjustment by the surgeon, further extending the time of the surgical operation.

[0004] In the prior art, there are also single-port laparoscopic breast surgery flap freeing methods using surgical scalpels, in order to reduce the risk of burns and seroma during the operation, speed up the operation, and improve the overall efficiency of the operation. However, due to the obvious bulge and curvature of the breast and thorax, it is difficult for traditional straight-rod scalpels to cross the natural curvature of the breast and thorax, which increases the difficulty and risk of the operation. In addition, the handle of the existing scalpel is relatively short. During laparoscopic surgery, especially when the surgical incision is located in the relatively narrow space of the armpit, the single-port incision located in the armpit during laparoscopic surgery cannot reach the boundary of the breast when the scalpel is inserted. This limitation not only affects the accuracy and effect of the operation, but may also lead to a longer operation time and an increase in the patient's recovery period. Summary of the invention

[0005] In response to at least one of the problems in the above-mentioned prior art, the purpose of the utility model is to provide a curved knife handle for laparoscopic breast surgery, which is more adapted to the physiological curvature of the breast and thorax, facilitates the optimization of the knife handle angle and precise measurement during surgery, so as to ensure that the surgical area can be reached accurately and efficiently during laparoscopic surgery, thereby facilitating the separation of the breast flap during surgery, reducing bleeding, protecting the nipple-areola complex and the posterior milk ducts, shortening the operation time, and reducing the risk of flap necrosis.
