Embodiment 1

[0047] Such as Figure 1 to Figure 9 As shown, a resection device for patients with intestinal polyps of the present invention includes a cannula 2, the end of the cannula 2 is provided with a first endoscope body 1, and the cannula 2 is provided with a first The trachea 8, the first trachea 8 is sleeved on the intubation tube 2, one end of the first trachea 8 is provided with a fixed block 9 of cylindrical structure, the fixed block 9 is close to the first endoscope body 1, and the fixed block 9 is provided There is a cavity, and the other end of the first air pipe is provided with a first air pump. The first air pipe 8 is provided with two conical rods 7, and the two conical rods 7 are both located in the cavity of the fixed block 9, and the conical rod 7 can be arranged along the Move along the axial direction of the first air pipe 8, and the diameters of the two conical rods 7 gradually decrease in the direction away from each other. A fixing plate 5 is provided between the...

Embodiment 2

[0049] On the basis of embodiment 1, the inner support assembly includes a first arc-shaped plate 3 with elasticity and two movable rods 12, one end of the two movable rods 12 is connected to both ends of the first arc-shaped plate 3, and the other One end extends into the fixed block 9. When the conical rod 7 moves away from the fixed plate 5, the inclined surface of the conical rod 7 can push the movable rod 12 to extend in the radial direction of the fixed block 9.

Embodiment 3

[0051] On the basis of embodiment 2, the movable rod 12 is further provided with a ball block 14 on the end of the cavity in the fixed block 9, and the movable rod 12 is also provided with a second elastic member 13, and the second elastic member 13 Located between the ball block 14 and the inner wall of the fixed block 9 cavity.

Abstract

The invention discloses excision equipment applied to patient intestinal polyp applications. The excision equipment comprises an intubation tube, a first endoscope body is arranged at the tail end ofthe intubation tube, a first air tube is arranged on the intubation tube, the intubation tube is sleeved with the first air tube, a fixed block of a cylindrical structure is arranged at one end of thefirst air tube, and a cavity is formed in the fixed block; two conical rods are located in a cavity of the fixed block, a fixed plate is arranged between the two conical rods, and telescopic tubes are arranged on two sides of the fixed plate; inner supporting components of arc-shaped structures are arranged on the two sides of the fixed block; a cutting component is further arranged on the fixedblock, and a second endoscope body is further arranged on the cutting component; a second arc-shaped plate is further arranged between the two conical rods on the first air tube, the two ends of the second arc-shaped plate are connected with the two conical rods respectively, the center of the second arc-shaped plate is further connected with the cutting component, and when the two conical rods get close to the fixed plate, the second arc-shaped plate can push the cutting component to stretch out in the radial direction of the fixed block.

Description

Technical field [0001] The invention relates to the technical field of medical equipment, in particular to a resection equipment for patients with intestinal polyps. Background technique [0002] Polyps are neoplasms that grow on the surface of human tissues. Modern medicine generally refers to neoplasms that grow on the surface of human mucosa as polyps, including proliferative, inflammatory, hamartoma, adenoma, and other tumors. Polyps are a kind of benign tumors. The clinical manifestations are mostly inflammatory polyps, adenomatous polyps and certain gastrointestinal polyp syndromes. Although these lesions are benign, some of them have a tendency to become malignant. Cysts that grow under the skin, lipomas in adipose tissue, fibroids in muscles, etc., can also cause uplifts on the body surface, but they are not in the category of polyps. In medicine, it is generally named according to the part where it appears. For example, those that grow on the vocal cords are called "vo...
