Embodiment Construction

[0030] The present invention will be further described below in conjunction with specific drawings.

[0031] Such as figure 1 As shown, the endoscopic scalpel with a pulling device includes an endoscopic cutting system 1 for excision of diseased tissue in endoscopic surgery, and is used to pull the diseased tissue under endoscope to expose the cut site The cutting site is exposed under the endoscope camera and displayed on the display screen so that the surgeon can use the endoscope cutting system 1 to accurately cut the endoscope pulling system 2, and to transfer the endoscope cutting system 1 and the endoscope pulling system 2 Operation sleeve 3 to the endoscopic surgical site.

[0032] During specific implementation, the endoscopic scalpel with a pulling device is mainly used for digestive tract endoscopic surgery, such as gastroscopic and colonoscopic surgery. It needs to be inserted through the operating cavity of the gastroscope or colonoscope. The inner diameter of th...

Abstract

The invention discloses an endoscopic scalpel with a pulling device. The endoscopic scalpel comprises an endoscopic cutting system, an endoscopic pulling system and an operation sleeve; the endoscopic cutting system comprises a cutting scalpel head which is arranged at the head end and used for cutting lesion tissue, a transferring rod used for transferring tail operation to the cutting scalpel head of the scalpel head portion and an operation handle arranged at the tail end; the endoscopic pulling system comprises a fixing head which is arranged at the head end and used for temporarily fixing the lesion tissue, a pulling rod connected with the fixing head and a pulling handle arranged at the tail end of the pulling rod, wherein the head end of the pulling rod is formed through J-shaped moulding, and the cross section of the pulling rod is in a non-circular shape. According to the endoscopic scalpel with the pulling device, the lesion tissue is pulled open to be exposed in a visual operative field through J-shaped moulding of the head end of the pulling rod, the pulling degree of further adjusted through the pulling handle, and therefore a surgical doctor can clearly observe the surgical cutting portion and conveniently use the endoscopic cutting system to precisely cut off the lesion tissue.

Description

technical field [0001] The invention relates to an endoscopic scalpel, in particular to an endoscopic scalpel with a pulling device, belonging to the technical field of medical instruments. Background technique [0002] Endoscopic surgery can resect the diseased tissue in the human cavity when it is small. It has the advantage of minimally invasive early and has irreplaceable advantages in the treatment of the diseased tissue in the patient's cavity. Direction of development. [0003] At present, the endoscopic scalpel, especially the endoscopic scalpel in the deep part of the long lumen (such as urinary tract, digestive tract, airway), is extremely difficult to operate, because when cutting the lesion tissue with a slightly larger area, the edge of the lesion tissue is flat. The paving part often covers the operating part of the endoscopic scalpel, so that the field of view of the electronic screen of the endoscopic operation cannot smoothly observe the surgical incision s...
