Abstract

The utility model discloses an absorbable wire structure with double flat-head round needles for breast prosthesis reconstruction, which comprises flat-head round needles and absorbable wires, wherein the flat-head round needles are fixedly connected with two ends of each absorbable wire; the absorbable thread is in seamless connection with the flat-head round needle. The flat head round needle is arc-shaped and has bidirectional symmetry. The absorbable thread is 50cm long and is an absorbable thread, the thread is made of Polydioxanone (Polydioxanone), the absorbable medical suture is applicable to suturing and ligating skin soft tissues, can be degraded and absorbed by a human body after being implanted into the human body tissues, and does not need to be removed, so that the pain of patient in removing the suture is avoided. The structure of the utility model is different from the current clinical use, the design of the double flat-head round needle and the absorbable thread is more convenient for the clinical operation of mammary gland reconstruction suture, and the prosthesis is not easy to contusion, the utility model can reduce the damage to the autologous tissues of other parts and reduce the risk of secondary operation for patients.

Description

Absorbable wire structure with double flat-head round needles for breast prosthesis reconstruction

Technical Field

The utility model relates to the field of medical instruments, in particular to an absorbable thread with a double flat-head round needle for breast prosthesis reconstruction.

Background

In clinic, the immediate prosthesis reconstruction after the breast cancer resection is the choice of more and more breast cancer patients, wherein the prosthesis reconstruction can be selected by more and more patients along with the improvement of living standard of people and less damage to the patients, the postoperative complication probability is small, and more patients can select the prosthesis reconstruction. However, most of breast suture needle heads are generally triangular in clinic at present, the breast suture needles are sharp and easy to damage the prosthesis, and the separation of the needles and the threads brings inconvenience to operators.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provides an absorbable thread with a double flat-head round needle for breast prosthesis reconstruction.

The purpose of the utility model is realized by the following technical scheme: an absorbable wire structure with double flat-head round needles for breast prosthesis reconstruction comprises flat-head round needles and absorbable wires, wherein the flat-head round needles are fixedly connected with two ends of each absorbable wire;

further, the absorbable thread is in seamless connection with the flat-head round needle.

Furthermore, the flat head round needle is arc-shaped and has bidirectional symmetry.

Furthermore, the absorbable thread is 50cm in length and is an absorbable suture line, the thread is made of polydioxanone, the absorbable suture line is suitable for suturing and ligating skin soft tissues, and after the absorbable suture line is implanted into human tissues, the absorbable suture line can be degraded and absorbed by a human body without being detached.

The utility model has the beneficial effects that: the structure of the utility model is different from the current clinical use, the design of the double flat head round needle and the absorbable thread is more convenient for the clinical operation of mammary gland reconstruction suture, the prosthesis is not easy to contusion, the damage to the autologous tissues of other parts can be reduced for patients, and the risk of secondary operation is reduced.

Drawings

FIG. 1 is a schematic view of the structure of the present invention;

in the figure, 1, a flat head round needle; 2. the thread can be absorbed.

Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

As shown in figure 1, the absorbable wire structure with double truncated round needles for breast prosthesis reconstruction provided by the utility model comprises the truncated round needles 1 and an absorbable wire 2, and the truncated round needles 1 are arranged at both ends of the absorbable wire 2, so that the clinical operation is convenient. The flat-head round needle 1 is arc-shaped and has bidirectional symmetry, the absorbable thread 2 is seamlessly connected with the flat-head round needle 1, and the needle and the thread are integrated, so that the suture can be carried out bidirectionally when the mammary prosthesis is sutured, the range can be selected, and the operation in the operation is facilitated. The length of the absorbable thread 2 is 50cm, the upper part and the lower part of the reconstructed breast of the prosthesis are respectively 20-30cm generally, the left side and the right side are respectively about 10cm, the absorbable thread 2 is an absorbable multi-strand braided suture, the surface of the absorbable multi-strand braided suture is lubricated by a mixed machine of ethyl lactide and calcium stearate, the absorbable multi-strand braided suture is implanted into a human body for 56-70 days and is completely absorbed, and the absorbable suture is a novel suture material for avoiding the pain of the patient in removing the suture.

The flat-head round needles are arranged at two ends of the body, after the prosthesis is placed, the flat-head round needles are tightly attached to the prosthesis to be used for sewing muscle fascia tissues or the reticular patches when the prosthesis is fixed, a tightly attached bag is made for the prosthesis to play a role in fixing the prosthesis, the design of the two ends can be more flexible when the bag is sewn, meanwhile, the flat heads are flat, the prosthesis cannot be damaged when the flat-head round needles are tightly attached to the prosthesis, and the design of absorbable threads is beneficial to the fusion of the fascia muscle tissues and the reticular patches.

The above-described embodiments are intended to illustrate rather than to limit the utility model, and any modifications and variations of the present invention are within the spirit of the utility model and the scope of the appended claims.
