Problems solved by technology

[0003] However, due to the complex processing of the blade with the arc scalpel blade, there are the following disadvantages in manual polishing: first, manual polishing relies on manual operation experience, and the polishing of the blade must be done by skilled operators. The effect of polishing by novice operators may not be ideal, and may even damage the blade; second, there is a safety hazard for the operator to perform polishing by holding the blade; third, the efficiency of manual polishing is low
However, the blade needs to be turned over and transported during the two clampings. This process is time-consuming and labor-intensive, and also reduces the processing progress.

Embodiment 1

[0055] Embodiment 1: A polishing jig with a circular arc scalpel blade

[0056] Such as Figure 1-2 As shown, the polishing fixture includes a knife holder 1 having a clamping mechanism for clamping a surgical blade 4 . The clamping mechanism has two working states: a clamping state and a loosening state. When in the clamping state, the clamping mechanism clamps the surgical blade 4 in the knife holder 1; when in the relaxed state, the clamping mechanism releases the surgical blade 4.

[0057] The polishing fixture also includes a track bottom plate 2 on which the tool holder 1 is placed. An arc-shaped track 21 and a matching body 17 matched with the arc-shaped track 21 are arranged between the track bottom plate 2 and the tool holder 1 . Such as Figure 1-2 As shown, in this embodiment, the arc-shaped track 21 is located on the track base plate 2, and the arc-shaped track 21 is convex, and the corresponding matching body 17 is a concave groove body at the bottom of the kn...

Embodiment 2

[0090] Embodiment 2: A polishing fixture with a circular arc scalpel blade

[0091] Such as Figure 5-6 As shown, the rest is the same as the first embodiment, the difference is that: the clamping mechanism includes a static clamping plate 10, and the static clamping plate 10 is fixed relative to the tool holder 1. A movable splint 11 is stacked on the static splint 10 , and a tension spring 15 acts on the movable splint 11 , and the tension spring 15 forces the movable splint 11 to move toward the direction close to the static splint 10 . A panel 12 is also provided between the static splint 10 and the movable splint 11, and there is an inclined-plane matching relationship between the panel 12 and the movable splint 11. It is inclined in the direction in which the panel 12 is embedded between the static splint 10 and the movable splint 11 .

[0092] Wherein, the slope matching relationship between the panel 12 and the movable splint 11 is composed of a sliding fit between t...

Abstract

The invention relates to a knife edge polishing and grinding fixture provided with an arc-shaped scalpel. The knife edge polishing and grinding fixture comprises a knife clamping base and a rail baseplate, the knife clamping base is provided with a clamping mechanism used for clamping a scalpel blade, the knife clamping base is placed on the rail baseplate, an arc-shaped rail and a sliding body or a rolling body are arranged between the knife clamping base and the rail baseplate, and a swing mechanism is formed by the knife clamping base and the rail baseplate by matching of the arc-shaped rail and the sliding body or the rolling body; in a working state, when the scalpel blade is clamped by the knife clamping base, the arc-shaped center of the edge of the scalpel blade and the center of the arc-shaped rail are concentric; when external force is acted on the knife clamping base, the knife clamping base swings on the rail baseplate along the arc-shaped rail. According to the knife edge polishing and grinding fixture, the structure is simple, the conception is ingenious, the cost is low, and the work efficiency is high. By means of the simple structure, double-faced polishing and grinding which cannot be achieved in the prior art are achieved, and the polishing and grinding machining efficiency of the scalpel blade is improved in multiples.

Description

technical field [0001] The invention relates to a scalpel production equipment, in particular to a fixture on the knife edge polishing equipment, in particular to a fixture suitable for the knife edge polishing equipment with a circular arc scalpel. The scalpel blade polishing equipment refers to blade polishing equipment, blade grinding equipment or blade grinding and polishing equipment. Background technique [0002] The production of surgical blades in China has a history of more than 50 years. Among them, the production and processing of blades with arc-shaped scalpel blades is relatively complicated. There are two kinds of blades with arc scalpel blades, one is that the blade of the scalpel blade is only arc-shaped, and the other is that the blade of the scalpel blade is formed by connecting a straight line segment and an arc segment. For a long time, the polishing process of the arc scalpel blade all adopts manual polishing, and the polishing is realized on the polish...
