Embodiment 1

[0021] like figure 1 , figure 2 , image 3 As shown, a multi-directional dilating tube endoscope includes a dilating tube 1 made of elastic coiled plates. In a relaxed state, the elastic coiled plates are crimped under their own elastic force to form two overlapping layers. In the cylinder cavity of the expansion cylinder 1, a pair of reel brackets 6 are welded in the middle of the inner end of the elastic coil plate of the expansion cylinder 1, and a rotatable reel 2 is arranged on the reel support 6, and the two ends of the reel 2 are respectively connected to the two reel brackets 6 Above, a flexible belt 3 is wound on the reel 2, and the flexible belt 3 extends between the elastic coil layers of the expansion cylinder 1. One end of the flexible belt 3 is fixed on the reel 2, and the other end is fixed on the outer end of the elastic coil of the expansion cylinder 1. . The expansion cylinder 1 is wrapped with an elastic membrane 4 . A rotary handle 5 is provided at the...

Embodiment 2

[0024] like Figure 4 As shown, the reel 2 is a segmented structure, including a driving section 9 and a driven section 10, the driving section 9 is provided with external threads, the outer wall of the driven section 10 is smooth, the flexible belt 3 is wound on the driven section 10, and The handle 5 is arranged at the head end of the driving section 9, the end of the driving section 9 is provided with a spline, the driven section 10 is a hollow structure, and a spline groove matching the spline of the driving section is provided inside, and the driven section 10 is sleeved outside the end of the driving section 9, The driving section 9 and the driven section 10 form a sliding socket, and at the same time form a transmission connection through splines. The reel locking mechanism includes a threaded seat 11 and a locking ring 12. The threaded seat 11 is fixed on the elastic roll of the expansion cylinder 1. At the inner end of the plate, the driving section of the reel 2 is s...

Abstract

The invention discloses a multidirectional expansion cylinder-type inner speculum comprising an expansion cylinder which is made by rolling elastic roll plates; a rotary reel is installed at the inner end of the elastic roll plate of the expansion cylinder; the reel is coiled with a flexible band; the flexible band extends in the elastic roll plate of the expansion cylinder; one end of the flexible band is fixed on the reel and the other end is fixed on an outer end of the elastic roll plate of the expansion cylinder; the expansion cylinder is also provided with a reel latching mechanism. According to the invention, the integral expansion of the expansion cylinder is realized through the reel winding the flexible band and the expansion forces of all directions are uniform so that a regular endoscopy channel is formed, which is not liable to bring discomfort to human bodies and the speculum is convenient to use.

Description

technical field [0001] The invention relates to a medical instrument, more specifically, it relates to a multidirectional dilating barrel endoscope. Background technique [0002] Endoscope is a common medical device, which is used to enter the body from the cavity of the human body to observe and diagnose internal lesions. In order to fully stretch the cavity of the human body for more clear observation, the endoscope usually has a dilated At present, the most commonly used endoscope in clinical practice is the clamp-type structure, but the structure of the clamp-type endoscope determines that it can only move in two directions when it is stretched, which makes it difficult to achieve uniformity in all directions in the human body cavity. Expansion is not conducive to the formation of regular endoscopic channels, but also easily causes discomfort to the human body, so the existing endoscopes need to be improved. The utility model whose publication number is CN201870619U dis...
