Problems solved by technology

[0002] During mastectomy, an electric knife is used to dissect the free skin flap sharply starting from the subcutaneous fat tissue. As the skin flap gradually frees up, the flap needs to be pulled up to expose the remaining tissue to continue the operation. At present, multiple assistants use hemostatic forceps Or towel forceps to pull up the skin flap, the alveolar structure of the hemostat and towel forceps will cause great damage to the skin, and will leave a large area of ​​permanent scars after the operation, and once the skin flap is loosened during the operation, it is likely to Burns from contact with electric knife
In addition, the operation of multiple assistants affects the surgical field of view and reduces the efficiency of the operation
[0003] Although there are some retractors specially used for mastectomy in the prior art, the front end of the retractor is blunt. In actual operation, it is impossible to lift the free skin flap to a certain height, and wrinkles will still appear. Once wrinkles appear, It will greatly affect the accuracy of electric knife cutting

Embodiment 1

[0024] Combine figure 1 , figure 2 , image 3 with Figure 4 As shown, a surgical retractor of the present invention includes a rod body 1, a hook portion 2 and a rotating rod 3. The rod body 1 is provided with a slot 4 along the axial direction. The rotating rod 3 is installed in the slot 4 through the rotating shaft 5. The rotating rod The two ends of 3 extend to the same side of the rotating rod 3 along the circumference to form a first tongue 6 and a second tongue 7. The other side of the rotating rod 3 corresponding to the first tongue 6 is provided with a protective cap 8, and the protective cap 8 opens. There is a tapered groove 9, and the rod body 1 is close to the upper end of the notch 4 to form a tooth seat 10 along the circumference to one side. The first tongue 6, the second tongue 7 and the tooth seat 10 are all arc structures with the same width. The first snap tongue 6 and the second snap tongue 7 are provided with several tooth grooves, and the tooth seat is pr...

Embodiment 2

[0028] Please further combine Figure 5 As shown, Figure 5 It is a bottom view schematic view of a retractor used for mastectomy. 4 surgical retractors as described in Example 1 are installed, including an arc-shaped frame 12 with an arc-shaped opening 11 under the inner hollow, and a movable connection with the arc-shaped frame 12 The upper end of the surgical hook is provided with a spherical body 13 that can be accommodated in the arc-shaped frame 12, and the outer arc surface of the arc-shaped frame 12 is connected with a handle 14 extending obliquely upwards. For the specific structure of the surgical hook, refer to Embodiment 1.

[0029] A number of bayonet openings 15 for accommodating the surgical hook rod 1 are opened on the side of the arc-shaped opening 11 near the inner arc surface. When the number of surgical hooks is 4, the number of bayonet points is appropriate.

Abstract

The invention discloses a surgical retractor and a combined retractor for mastectomy. The surgical retractor includes a rod body, a sharp hook portion and a rotary rod. When the body is in the second position, the hook part is received in the groove of the protective cap. The retractor for mastectomy includes an arc-shaped frame with an arc-shaped opening below the hollow interior, and several surgical retractors movably connected with the arc-shaped frame. The upper end of the surgical retractor is provided with a spherical body that can be accommodated and slid in the arc-shaped frame. The invention uses small sharp pointed hooks to puncture the skin flap for lifting, which can effectively ensure that the skin flap is in a state of constant tension, and no wrinkles will affect the operation. The protective cap can close the hook body to prevent the skin flap from detaching from the hook body. When in use, two sets of retractors are used to lift the skin flaps on both sides of the incision from the left and right, and only one assistant is needed.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a retractor for mastectomy and the combination with the retractor frame. Background technique [0002] During mastectomy, an electric knife is used to dissect the free skin flap sharply starting from the subcutaneous fat tissue. As the skin flap gradually frees up, the flap needs to be pulled up to expose the remaining tissue to continue the operation. At present, multiple assistants use hemostatic forceps Or towel forceps to pull up the skin flap, the alveolar structure of the hemostat and towel forceps will cause great damage to the skin, and will leave a large area of ​​permanent scars after the operation, and once the skin flap is loosened during the operation, it is likely to Contact with the electric knife can cause burns. And the operations of multiple assistants affect the operative field of view, which reduces the operative efficiency. [0003] Although there are some re...
