Problems solved by technology

The cutting device requires the cutting head to move in a linear direction and cut the sutures equidistantly. Due to various factors such as cutting distance adjustment and cutting line replacement, it is necessary to frequently adjust the relative position between the cutting head and the sutures. Adjustment will directly affect the quality of the suture

Abstract

The invention discloses a cutting device for high-precision barb suture lines, relates to the technical field of medical suture line processing equipment, and aims to solve the problems that the accuracy cannot be ensured by adjusting the relative position between a cutting head and the suture lines, the quality is influenced. According to the technical scheme, chucks located at the two ends of a workbench respectively are arranged on the workbench, and the chucks fix to the corresponding ends of the suture lines correspondingly; a transverse rod is arranged above the workbench in the horizontal direction and provided with a first guide rail and a first grating ruler which extend in the length direction of the suture lines, a first linear motor is arranged at one end of the first guide rail, a cutting part slidably installed on the first guide rail is fixed to the output end of the first linear motor, and a photoelectric sensor is fixed to the transverse rod; and a sensor sheet corresponding to the photoelectric sensor is fixed to the cutting part, and a first reading head corresponding to the first grating ruler is fixed to the cutting part. According to the cutting device, the precision of adjusting the relative distance between the cutting head and the suture lines is improved, and the cutting precision of the suture lines is improved.

Description

technical field [0001] The invention relates to the technical field of medical suture processing equipment, in particular to a high-precision barbed suture cutting device. Background technique [0002] Suture thread is widely used in the suturing of the wound of operation and trauma, and one end of suture thread is tied on the surgical needle, and surgical needle pulls suture thread through tissue to make wound suturing and tissue fixed connection together to heal and regenerate, and at present Most sutures require one or more knots to hold the suture in place, and knotting increases operative time and has serious consequences for some procedures. Compared with the traditional sutures that need to be knotted to fix the tissue, the use of barbed medical sutures can exert tension in the tissue and reduce the suture slippage at the wound, shorten the operation time, and reduce the need for traditional knots. Complications such as infection due to detachment or breakage of sutu...
