Problems solved by technology

Manual grinding of triangular points mainly has the following disadvantages: (1) The efficiency of sharpening is very low; (2) The appearance of the product is poor; (3) The strength of the needle tip is poor. The protruding surface cannot be ground on the side surface, and "virtual points" often appear. After several punctures, the "virtual points" will break off and cause a sudden increase in puncture resistance.

Embodiment Construction

[0028]As shown in Figures 1 to 11, the device includes a clamping mechanism 1, a swing mechanism and a grinding wheel mechanism 2 mounted on a frame 7. The clamping mechanism 1 includes a needle-loading part and an overturning part, and the needle-loading part consists of a cloth needle Plate 1-4 and needle pressing plate 1-21. On the needle cloth plate 1-4, there are several continuous adjacently distributed needle grooves 1-29 with a triangular cross-section. The needle cloth plate 1-4 is located on the needle groove 1-29. There are needle-rubbing plate grooves 1-30, the needle-distributing plate 1-4 is installed on the needle-distributing plate cushion block 1-32 with the needle-rubbing plate groove 1-30, and the needle-distributing plate cushion block 1-32 is installed on the clamping base On 1-31, the two sides of the clamping base 1-31 are installed on the swing bearing seats 4 and 12 through the swing shafts 1-5 and 1-8, and the pins 1-25 and 1 at both ends are used abov...

Abstract

The present invention discloses a triangle tip device for grinding surgery needle. The device comprises a clamp-loading mechanism (1), a swing mechanism and an abrasive wheel mechanism (2) which are installed on a frame (7). The clamp-loading mechanism comprises a needle loading part and an overturning part. The surgery needles are distributed on the needle grooves (1-29) of needle distribution board (1-21) of needle loading part. The abrasive wheel mechanism (2) grinds the surgery needles. Simultaneously, the clamp-loading mechanism (1) realizes 120 DEG overturning of surgery needle through an overturning part. The clamp-loading mechanism (1) realizes the swinging in grinding through a swing mechanism. The device of the invention has the advantages of mechanical operation, reduced labor intensity of worker, increased labor efficiency and guaranteed grinding quality.

Description

technical field [0001] The invention relates to a surgical needle grinding device, in particular to a surgical needle grinding triangle tip device. Background technique [0002] Surgical needles are indispensable disposable medical instruments in surgical operations. Surgical needles are generally curved into an arc shape. From the cross-section, surgical needles can be divided into round needles and triangular needles, which all need to be sharpened before being bent. The sharpening method of the round needle is the same as that of the sewing needle, which has a long history and mature technology; the sharpening of the triangle needle is very backward because of its special purpose and unpopularity. The sharpening method of domestic surgical needle manufacturers is to clamp the surgical needle on a jig, and hold the jig to sharpen the tips one by one on the grinding wheel or belt. The main disadvantages of manual grinding of triangular tips are: (1) the sharpening effici...
