Embodiment 1

[0041] Example as Figure 1-6 shown. The expansion control mechanism in this embodiment is two crowbars 3 respectively corresponding to the two wings 101 . The front end of the crowbar 3 is welded and fixed at the middle front position outside the wing 101 , and the rear end extends towards the rear end of the operating handle 2 and coincides with the operating handle 2 correspondingly. The front ends of the two wing parts 101 can be opened against the elastic force of the spring steel sheet 102 by holding the rear ends of the two crowbars 3 with one hand and pressing them together. Furthermore, by repeatedly pressing the rear ends of the two crowbars 3 together with the elastic potential energy of the spring steel sheet 102, the front ends of the two wings 101 are reciprocated to open and close alternately, realizing the expansion-type stripping operation. In order to prevent the crowbar 3 from protruding and interfering during the stripping operation, a groove for accommod...

Embodiment 2

[0051] Example two such as Figure 7 and Figure 8 shown. The difference between this embodiment and Embodiment 1 in terms of effect is that it can be operated completely with one hand, completely liberating the other hand of the medical worker. The structural difference from the first embodiment is not only the arrangement of the aforementioned crowbar 3 , but also the way of triggering the rotation of the column core 11 . The outside of the column core 11 in the present embodiment is no longer provided with a handwheel 8, but as Figure 8 As shown, a driving rod 17 is fixed on the outer periphery of the column core 11, and the column core 11 is driven to rotate by the driving rod 17. like Figure 7As shown, the operating handle 2 is provided with a second strip-shaped hole 18 for the driving rod 17 to protrude. The second strip-shaped hole 18 is distributed along the circumferential direction of the operating handle 2, so that the operator can move the lever 17 to drive...

Embodiment 3

[0053] Embodiment three such as Figure 9-11 shown. In this embodiment, the operating handle 2 has a second axial hole communicating with the inner cavity of the stripping head 1 . The expansion mechanism is a second push rod 20 slidingly installed in the second axial hole. The front end of the second push rod 20 is distributed in the inner cavity of the peeling head 1 and is provided with a support block for expanding the two wings 101 26. The action end of the clamp portion of the support block 26 is wedge-shaped. After the support block 26 is continuously pushed forward by the second push rod 20, the front ends of the two wings 101 are stretched apart by the support block 26 to achieve the expansion and peeling effect.

[0054] The second push rod 20 has the same third axial hole as the inner cavity of the stripping head 1 . The cutting control mechanism includes a third push rod 19 which slides through the third axial hole, and the front end of the third push rod 19 is ...

Abstract

The invention relates to the field of plastic surgery medical instruments, in particular to a blunt type, expanding type and cutting-off type composite integrated breast detacher. The composite integrated breast detacher comprises a wedge-shaped stripping head, wherein the front end of the stripping head is a stripping part, and an operating handle is fixedly arranged at the rear end; the stripping head is of a hollow structure and is provided with two wing parts with the front ends capable of being opened and closed, and the front ends of the two wing parts are closed in a normal state so that blunt stripping operation can be carried out through the closed front ends of the two wing parts. An expansion control mechanism is arranged on the stripping head, and the front ends of the two wingparts can be controlled to be opened and closed in a reciprocating manner through the expansion control mechanism so as to carry out expansion type stripping operation; a cutting knife is further arranged in an inner cavity of the stripping head, a cutting control mechanism used for controlling the cutting knife to stretch out of the opened wing part is arranged on the operating handle, and cutting type stripping operation can be carried out through the cutting knife stretching out of the wing part. The optimal stripping mode can be selected according to the bonding strength between skin andsubcutaneous tissues, the stripping operation time is shortened, and the pain of a patient is relieved.

Description

technical field [0001] The invention relates to the field of plastic surgery medical equipment, in particular to a blunt, expansion and cut-off combined breast stripper. Background technique [0002] In female breast augmentation cosmetic surgery or accidental breast plastic filling surgery, it is necessary to make an incision around the breast, and then extend the breast peeler into the breast from the incision, peel off the epidermis and subcutaneous tissue, and form a breast of appropriate size between the epidermis and subcutaneous tissue. Finally, implant a filling prosthesis into the accommodation cavity through the incision and suture. [0003] Breast strippers in the prior art are varied in structure and function, and the most common one in structure is a U-shaped stripper. The ends of the two stripping arms of the U-shaped stripper are provided with arc-shaped blunt heads, one of which is a straight arm, and the other has a specific angle. During the breast stripp...
