Abstract

The invention belongs to the technical field of medical instruments and relates to a minimally-invasive mammary gland tumor excision apparatus and a utilization method thereof. The minimally-invasive mammary gland tumor excision apparatus integrates excision and extraction devices used in a minimally invasive surgery. The apparatus comprises a sleeve and a gripping device operating rod and is characterized in that a sheet type gripping device and an excision device are arranged in the sleeve. In use of the apparatus, small-incision remote control can be realized, and a user can align the apparatus to a tumor in a body of a patient, control the gripping device operating rod to grip a to-be-excised part and extend a rotary tool holder at the same time to close at the bottom of the to-be-excised part, and finally rotate the operating rod to make the tool holder rotate for excising a tumor, wherein the excised tumor is retained in the gripping device and taken out of the body by the same. The minimally-invasive mammary gland tumor excision apparatus is small, flexible, simple in mounting and demounting, convenient to clean, small in external wound and available for small-incision remote control, surgery time is shortened, less bleeding is realized, and pains and physiological burden of the patient can be effectively alleviated.

Description

technical field [0001] The invention relates to a breast minimally invasive tumor resection device and a method for using the same, belonging to the technical field of medical devices. Background technique [0002] In minimally invasive tumor resection surgery, surgeons have long pursued the surgical goal of minimal trauma and high efficacy; they strive to take into account the aesthetic and psychological effects of patients while curing the disease. However, the surgical resection tools currently used have single functions, require large external wounds, separate tumor grasping devices and resection devices, and are complicated to operate. Moreover, in the process of tumor resection, repeated cutting and long operation time will cause the tumor to fall off easily and pollute the internal environment. [0003] Chinese patent CN205307049U discloses a minimally invasive surgery claw for tumor resection. The tumor claw described in this utility model includes a plurality of cu...
