Description

Technical Field

[0001] The invention relates to the technical field of breast surgery, in particular to a skin flap retractor for breast surgery. Background Art

[0002] Breast surgery mainly focuses on the surgical aspects of breast diseases: breast anatomy, breast infection, breast tumor pathology, principles of diagnosis and treatment of breast tumors, diagnosis of breast tumors and various surgical procedures for breast tumors, chemotherapy, radiotherapy and endocrine therapy. The skin flap is also called pedicled skin transplant. Modern views believe that a skin flap is a block of tissue composed of skin and subcutaneous tissue, which can be transferred from one part of the body to another. During the transfer process, one or two pedicles need to be connected, or they can be temporarily unconnected. After the transplant, vascular anastomosis is performed. During flap surgery, the skin flap needs to be pulled for suture, or a flap retractor can be used to pull the surgical incision open to facilitate the doctor's operation.

[0003] For example, a Chinese invention patent, publication number CN113876373B, discloses a skin flap retractor for use during breast surgery. The skin flap at the surgical site can be retracted in all directions through a retraction mechanism using multiple sets of retraction hooks in cooperation with a hollow ring. There is no need to adjust the position of the retractor multiple times during the operation, which facilitates the operation. The retraction mechanism automatically retracts unused retraction hooks through a coil spring, which avoids injuries to personnel caused by the retraction hooks during the operation, and facilitates the adjustment of the position of the retraction mechanism and the support mechanism to improve stability. However, in actual use, the adjustment method is relatively cumbersome and inconvenient for medical staff to use. Summary of the invention

[0043] During flap surgery, the flap needs to be pulled for suturing, or a flap retractor is used to pull open the surgical incision to facilitate the doctor's operation.

[0044] In the related art, the skin flap at the surgical site can be pulled in all directions through a pulling mechanism using multiple sets of pulling hooks in cooperation with a hollow ring. There is no need to adjust the position of the retractor multiple times during the operation, which facilitates the operation. The pulling mechanism automatically retracts unused pulling hooks through a coil spring, avoiding injuries to personnel caused by the pulling hooks during the operation, and facilitating the adjustment of the position of the pulling mechanism and the supporting mechanism to improve stability. However, in actual use, the adjustment method is relatively cumbersome and inconvenient for medical staff to use.

[0045] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a skin flap retractor for breast surgery. When it is needed, it is only necessary to push the slider 13 to make the slider 13 slide on the slide rail 12 while rotating the pulling mechanism 22. After adjusting the position and angle of the pulling mechanism 22, pull the ring body 431 upward, and while the groove body 40 limits the round head rod 26, it presses the round head rod 26 tightly, thereby achieving the limitation of the position and angle of the pulling mechanism 22, which is more convenient and quick, and improves the convenience of the device.

[0046] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0047] Combination Figure 1-Figure 6The embodiment of the present application provides a skin flap retractor for breast surgery, including: a ring body 10, a ring body 2 11 is fixedly connected to the top of the ring body 11, a slide rail 12 is fixedly connected to the outer side of the ring body 11, a slider 13 is slidably connected to the ring body 11 and the slide rail 12, a fixed seat 20 is fixedly connected to the top of the slider 13, a mounting seat 21 is rotatably connected to the fixed seat 20, a pulling mechanism 22 is installed on one side of the mounting seat 21, the pulling mechanism 22 is used to pull skin tissue, a telescopic plate 23 is arranged on the other side of the mounting seat 21, a slide groove 24 is opened on the top of the slider 13, an adjustment plate 25 is slidably connected in the slide groove 24, the The top of the adjusting plate 25 is rotatably connected to one end of the telescopic plate 23, a round head rod 26 is slidably connected to the slider 13, a slot 28 is provided on one side of the adjusting plate 25, one end of the round head rod 26 is inserted into the slot 28, a spring 27 is sleeved on the outside of the round head rod 26, and the two ends of the spring 27 are respectively fixedly connected to the slider 13 and the round head rod 26, a ring body 3 30 is fixedly connected to the top of the ring body 10, a ring body 4 31 is slidably connected to the ring body 3 30, a fixing bolt 32 is threadedly connected to the ring body 30, one end of the fixing bolt 32 is tightly pressed against the ring body 4 31, and a groove 40 is provided on the top of the ring body 4 31.
