AI Technical Summary
In existing techniques, it is difficult to accurately separate the proximal end of the pectoralis major muscle to the level of the nipple and areola through the axillary incision approach during breast augmentation surgery for Asian women, forming a three-plane cavity that affects the accuracy of the surgery.
A reverse dissector for axillary approach three-plane implant breast augmentation was designed, including a handle and a hook plate. The handle and hook plate are hollowly connected and equipped with a suction tube connector and a smoke vent. The end of the hook plate has an upward-curved arc-shaped head for endoscopic operation, which improves the accuracy of separation.
This instrument allows for precise endoscopic separation of the proximal end of the pectoralis major muscle down to the level of the nipple and areola, creating a three-plane layer that improves surgical precision, effectively removes intraoperative smoke, and enhances the safety and effectiveness of the surgical procedure.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a reverse dissector for axillary approach three-plane implant breast augmentation. Background Technology
[0002] Gentileschi proposed a three-plane breast augmentation technique. Through an areola incision, the pectoralis major muscle is transversely severed at the nipple level to the lateral edge of the sternum, forming a "three-plane" layer with the upper and lower parts behind the muscle and the central area behind the gland. Asian women usually undergo breast augmentation via an axillary incision approach. Under endoscopic assistance, the origin of the pectoralis major muscle is severed 1.5cm above the original inframammary fold. The proximal end of the severed pectoralis major muscle cannot be precisely separated to the nipple-areola level, thus forming a three-plane cavity. Utility Model Content
[0003] To address the shortcomings of existing technologies, this invention provides a reverse dissector for axillary approach three-plane implant breast augmentation, which solves the aforementioned problems.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: axillary approach three-plane implant breast augmentation reverse dissector, including a handle, wherein a hook plate is fixedly connected to the bottom end of the handle;
[0005] The bottom surface of the handle has multiple finger grooves, the top of the handle has a pressure relief hole, the end of the handle is fixedly connected to a straw connector, and the handle has a length mark.
[0006] The hook plate has an arc-shaped head that curves upwards at 15 degrees at its end, and a smoke vent is provided at the bottom of the hook plate.
[0007] Preferably, both the handle and the hook plate are hollow inside, and the handle and the hook plate are connected to each other, so as to facilitate smoke exhaust.
[0008] Preferably, the length of the handle is set to 25 cm to facilitate accurate marking of the pectoralis major muscle rupture site during surgery.
[0009] Preferably, the number of smoke exhaust holes is set to multiple, and the multiple smoke exhaust holes are evenly arranged on the bottom surface of the arc-shaped head, so that the smoke generated during the operation can be discharged.
[0010] Preferably, the widened arc-shaped head can increase the width of the arc-shaped head, thereby increasing the contact area and facilitating reverse operation.
[0011] Preferably, the handle and hook plate are integrally formed, which can be easily mass-produced using molds.
[0012] This invention provides a reverse dissector for a three-plane implant breast augmentation via the axillary approach. Compared with existing technologies, it has the following advantages:
[0013] 1. This axillary approach three-plane breast implant reverse dissector allows the hook plate to be inserted into the patient's body through the axillary incision by holding the handle, facilitating reverse operation. It precisely separates the lateral end of the proximal end of the pectoralis major muscle towards the head to the level of the nipple and areola, forming a "three-plane" layer with the upper and lower parts of the implant behind the muscle and the central area behind the glandular fascia, effectively improving the accuracy of the surgery.
[0014] 2. This axillary approach three-plane implant breast augmentation reverse dissector connects to a suction tube via a suction tube connector and uses a smoke vent to remove smoke during the operation, making it suitable for endoscopic procedures. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-3 This utility model provides a technical solution: a three-plane implant breast augmentation reverse dissector via the axillary approach, including a handle 1. The length of the handle 1 is set to 25 cm to facilitate accurate marking of the pectoralis major muscle cut ends during surgery. A hook plate 2 is fixedly connected to the bottom end of the handle 1. Both the handle 1 and the hook plate 2 are hollow inside, and the handle 1 and the hook plate 2 are connected to facilitate smoke extraction. The handle 1 and the hook plate 2 are integrally formed, which can be easily mass-produced using molds.
[0021] The bottom surface of the handle 1 has multiple finger grooves to facilitate the surgeon's grip on the hook. The top of the handle 1 has a decompression hole 5. The end of the handle 1 is fixedly connected to a suction tube connector 3, which can be connected to a suction tube to allow the smoke generated during the operation to be expelled using a smoke extraction device. The handle 1 has a length mark, which facilitates accurate marking of the pectoralis major muscle rupture position during the operation.
[0022] The end of the hook plate 2 is provided with an arc-shaped head 4 that curves upward at 15 degrees. The curvature of the hook plate 2 is adapted to the direction of the chest wall from the armpit to the breast. The arc-shaped head 4 is widened to increase the contact area and facilitate reverse operation. The bottom of the hook plate 2 is provided with a smoke exhaust hole 6. The number of smoke exhaust holes 6 is set to multiple and evenly distributed on the bottom surface of the arc-shaped head 4, so that the smoke generated during the operation can be discharged, which is suitable for endoscopic operation.
[0023] During the procedure, medical staff hold handle 1 and insert hook plate 2 into the patient's body through the axillary incision. This facilitates reverse operation and allows for precise dissection of the lateral end of the proximal pectoralis major muscle towards the head to the level of the nipple and areola. This creates a "three-plane" layering of the upper and lower parts of the prosthesis behind the muscle, and the central area behind the glandular fascia, effectively improving the precision of the surgery.
[0024] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
