Embodiment Construction

[0036] Such as Figure 5 , Figure 6 As shown, the tissue removal device of the present invention is mainly applicable to the removal of internal tissues of the human body, and consists of a gripping part 1 that is easy for the user to hold and a working part 2 that enters the inside of the human body to perform excision.

[0037] The holding part 1 can be made of materials such as metal or hard medical plastic, and can be made into a cylindrical or elliptical cylindrical shape that is easy to hold. There is a cavity inside it, which is convenient for setting components. One end connecting the holding part 1 with the working part can be made into a trapezoidal transition.

[0038] The working part 2 is basically an elongated structure, and the length can be selected.

[0039] Such as Figure 7 As shown, the holding part 1 and the working part 2 are detachably connected ( Figure 7 storage parts were also removed). The shells or external parts of the two can be fixedly con...

Abstract

The invention discloses a device for removing tissue. The device comprises a holding assembly capable of being conveniently held by a user and a working assembly, wherein the holding assembly is detachably connected with the working assembly, the holding assembly is provided with an exposed control part, and a driving device is arranged in the holding assembly and is provided with an output shaft; the working assembly comprises a thin and long guide part and a flexible shaft arranged inside the guide part, one end of the flexible shaft is in power connection with the output shaft, and the other end of the flexible shaft is a cutting working part; the cutting working part is provided with a plurality of cutting edges. Through the design of a split structure, the holding assembly with more devices and elements can be used repeatedly and is convenient to disinfect. The working assembly prone to abrasion is disposable and is convenient to replace. The combination of the holding assembly and the working assembly reduces the cost of every time of usage of the whole device.

Description

technical field [0001] The present invention relates to devices for tissue resection or removal using endoscopic surgery. In particular, it relates to devices for removing tissue from a patient's body. Background technique [0002] Endoscopic treatment is to allow surgical instruments to enter the human body through the natural passage of the human body or an artificially formed entrance (ie, a small incision) to achieve the treatment or treatment of human tissue. As endoscopic treatment is widely used, a large number of instruments for endoscopic treatment also appear. [0003] For different human organs and different pathologies, the treatment plan that needs to be adopted will be different. Different treatment plans correspond to different treatment measures, which leads to very strong specificity of endoscopic treatment instruments. [0004] In liver surgery, the main treatment measures currently available for early malignant liver lesions include: physical methods su...
