Description

Novel method for manufacturing knotting-free fishbone suture line

Technical Field

The invention relates to a medical suture, in particular to a novel method for manufacturing a knotting-free fishbone suture.

Background

The fishbone suture is generally used in the field of medical face-lifting, and mainly achieves the effect of lifting the face through non-surgical suspension by implanting absorbable PPDO (p-phenylene terephthamide) wires under the skin, lifting muscles, tightening the skin, stimulating collagen regeneration to increase the elasticity of the skin and improve and activate the skin. Has obvious effect of improving the face and has the efficacy of V-LINE.

The existing fishbone suture is a single-stranded wire, the single-stranded wire has the defects that the strength and toughness of the wire body are insufficient and the wire body is brittle, and the wire body is easy to break particularly when the face of a human body is affected by external force, so that the lifting effect of the face is reduced, particularly when the suture is arranged on the left and the right of the face, the permanent left-right asymmetry phenomenon is caused after the fracture of the suture on one side, and the difficulty of secondary operation treatment is increased steeply.

Detailed Description

The following description of the preferred embodiments of the present invention is provided for the purpose of illustration and description, and is in no way intended to limit the invention.

Example 1

The invention provides a novel method for manufacturing a knotting-free fishbone suture line, which comprises a common suture line and specifically comprises the following steps:

a. preparing, namely taking a common suture line with 1-2 small models as a main body, and performing aseptic treatment;

b. performing outer coating film treatment, namely adding a ppdo polymer and a pgla polymer serving as raw materials into a hopper for mixing, then preparing a film by a film scraping machine with five heating zones to obtain a medical film, and pressing a common suture line by an upper medical film and a lower medical film by an ultrasonic pressing machine to obtain a film suture line;

c. and (4) printing and cutting, namely embossing and cutting the film suture line by using an embossing cutting machine to finally obtain the fishbone barb type film suture line.

The five heating zones in the step b are respectively 120-130 ℃, 140-150 ℃, 150-165 ℃, 150-130 ℃ and 130-120 ℃, and the heating zones are arranged in sequence.

In step b, the ppdo polymer and the pgla polymer are mixed with the organic solvent in a hopper and stirred until complete dissolution, resulting in a polymer solution with a concentration of 10-20g per 100 ml.

Specifically, the traditional suture is a single-strand suture, although the suture is hard, the toughness is not enough, and the film body is made hard through a special film making technology, so that the generated fishbone structure can be very hard in a human body, and the fishbone structure plays a role in preventing back pull without knotting. Meanwhile, as 1-2 small common sutures are pressed in the membrane, even if the external membrane body is broken due to human tissues, the sutures can still play a role in suture connection and are matched with the fish bone structure pressed on the suture line, so that the whole line cannot collapse.

In the experiment, the common suture and the fishbone barb type film suture are mainly placed under a tensile strength tester for detection and microscope observation, the change of the fracture strength and the fracture elongation data of the suture under the agreeable environment is collected, the experiment times are ten times, and the final result is mainly the average value of the ten times, and is specifically shown in the following table:

as can be shown by the data in the above table, the fishbone line group has an inner and outer covering structure, and the overall stress is transmitted to each internal suture line mainly through the film on the surface when the fishbone line group faces the tensile direction, so that the stress is more uniform.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
