Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of endoscope anastomat, concretely relates to an endoscope anastomat steering structure. BACKGROUND

[0002] As a device for replacing traditional manual suture in clinical medicine, the anastomat is favored and respected by clinical surgeons at home and abroad. Compared with the traditional manual suture technology, the anastomat has the benefits of small tissue reaction, neat staple arrangement and equal spacing, which effectively avoids the problems of over-dense or over-dense manual suture and over-tight or over-loose ligation. At the same time, the anastomat for mechanical suture is easy to operate and can greatly shorten the operation time of the doctor.

[0003] The traditional anastomat steering mechanism realizes steering and steering locking functions through the relative sliding of the upper and lower tooth pieces. This structure may produce a clicking sound during movement, and the angle adjustment range is small, which cannot be finely adjusted and affects the use experience of the instrument. UTILITY MODEL CONTENTS

[0004] The utility model aims at the deficiencies of the prior art, and provides an endoscope anastomat steering structure to eliminate the noise during steering of the endoscope anastomat, increase the adjustable angle, and improve the use experience.

[0005] In order to solve the above technical problems, the utility model discloses an endoscope anastomat steering structure, which comprises an upper rotating shaft sleeve, a steering shaft assembly, a gasket, a clutch spring, a lower steering piece, an upper steering piece, a gland, and a steering knob. The upper rotating shaft sleeve is drivingly connected with the steering knob through the steering shaft assembly, the gasket, the clutch spring, and the lower steering piece are sequentially arranged on the steering shaft assembly, and the upper steering piece is fixedly connected with the steering knob through the gland. The lower end of the gland penetrates the upper steering piece and the lower steering piece and is connected with the clutch spring. Limiting steps are arranged on the opposite surfaces of the lower steering piece and the upper steering piece.

[0006] Further, the steering knob (8) is provided with a steering knob pin (9), and the upper end of the steering shaft assembly (2) is provided with a through groove corresponding to the steering knob pin (9).

[0007] Further, the steering knob (8) is provided with a positioning bead (10), and the gland (7) is provided with a groove corresponding to the positioning bead (10).

[0008] Further, the limiting steps arranged on the opposite surfaces of the lower steering piece (5) and the upper steering piece (6) are densely arranged to facilitate accurate fixing during steering adjustment of the endoscope anastomat.

[0009] Further, the length of the clutch spring (4) in relaxation is greater than the maximum distance of the lower steering vane (5) and the upper steering vane (6) in compression. When the steering knob (8) is released, the clutch spring (4) is in a relaxed state of stretching, the lower steering vane (5) is lifted and locked with the upper steering vane (6) under the action of the clutch spring (4), and when the steering knob (8) is pressed downward, the clutch spring (4) is in a compressed state, the lower steering vane (5) falls and separates from the upper steering vane (6) without the supporting action of the clutch spring (4).

[0010] Further, the clutch spring (4) is a single-piece spring or a multi-piece spring.

[0011] Advantages: Compared with the prior art, the utility model has the following advantages: the clutch of the upper steering vane and the lower steering vane is realized by pressing the steering knob downward, so that the purpose of eliminating noise is achieved when the anastomat is turned, and the adjustable angle is greatly increased, 360-degree rotation can be realized, the limiting steps are densely arranged on the opposite surfaces of the lower steering vane and the upper steering vane, which is beneficial to precise fixing when the endoscope anastomat is turned and adjusted, and is beneficial to subtle operation of the anastomat rotation direction adjustment, and the operation experience of the anastomat is improved.
