Abstract
The utility model discloses a kind of self-lubricating suture for being easy to take out stitches, including syringe needle, it further includes wire body, the wire body is fixedly connected with the left end of syringe needle, and the outer surface of the wire body is coated with self-lubricating coat in use that the right side of the syringe needle, which is equipped with tip,.By adding lubricant coating on the surface of suture, the coefficient of friction on suture surface is reduced, so that its sliding friction is smaller when taking out stitches, is easier to take out stitches, and the pain to caused by is smaller.By adding lubricant coating on the surface of suture, the coefficient of friction on suture surface is reduced, so that its sliding friction is smaller when taking out stitches, is easier to take out stitches, and the pain to caused by is smaller.The self-lubricating coat in use can be hydrophilic material such as polyvinylpyrrolidone etc., which can also be Teflon.The utility model relates to field of medical products more particularly to a kind of sutures.
Description
Technical field
The utility model relates to field of medical products more particularly to a kind of sutures.
Background technique
During surgical when encountering has biggish epidermis wound, it is often necessary to help wound by sewing up a wound
Healing.Existing memorial alloy suture is retained in supracutaneous alloy wire due to that can wrap up when the healing of wound soft tissue, in wound
When recovery from illness needs to take out stitches, during pulling out suture, since suture is circuitously to wear to connect on epidermis repeatedly, torn when taking out stitches
It draws soft tissue and sliding friction can be generated between soft tissue, and its skin-friction coefficient of general suture is larger, when taking out stitches
It is more inconvenient, and can also give artificial at stronger feeling of pain.
Utility model content
Technical problem to be solved by the utility model is: providing a kind of suture with self-lubricating coat in use, it is easier to tear open
Line, and pain when to take out stitches is smaller.
The solution that the utility model solves its technical problem is: a kind of self-lubricating suture for being easy to take out stitches, including
The right side of syringe needle, the syringe needle is equipped with tip, further includes wire body, the wire body is fixedly connected with the left end of syringe needle, institute
The outer surface for the wire body stated is coated with self-lubricating coat in use.
As a further improvement of the above technical scheme, the material of the wire body is ti-ni shape memory alloy.
As a further improvement of the above technical scheme, the material of the self-lubricating coat in use is hydrophilic material.
As a further improvement of the above technical scheme, the material of the self-lubricating coat in use is Teflon.
As a further improvement of the above technical scheme, the syringe needle is gradually reduced after becoming larger from tip.
As a further improvement of the above technical scheme, the left end of the syringe needle is equipped with blind hole, the wire body insertion
It is fitted tightly on together in blind hole and with the internal perisporium of blind hole.
The beneficial effects of the utility model are: reducing suture table by adding lubricant coating on the surface of suture
The coefficient of friction in face is easier to take out stitches, and the pain to caused by is smaller so that its sliding friction is smaller when taking out stitches.
The utility model relates to field of medical products more particularly to a kind of sutures.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described.Obviously, described attached drawing is a part of the embodiment of the utility model, rather than complete
Portion's embodiment, those skilled in the art without creative efforts, can also be obtained according to these attached drawings it
His design scheme and attached drawing.
Fig. 1 is the sectional front view of the utility model embodiment.
Specific embodiment
It is carried out below with reference to technical effect of the embodiment and attached drawing to the design of the utility model, specific structure and generation
It clearly and completely describes, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of the embodiment of the utility model, rather than whole embodiments, it is based on the embodiments of the present invention, the skill of this field
Art personnel other embodiments obtained without creative efforts belong to the model of the utility model protection
It encloses.In addition, all connection/connection relationships being previously mentioned in text, not singly refer to that component directly connects, and referring to can be according to specific reality
Situation is applied, by adding or reducing couple auxiliary, Lai Zucheng more preferably coupling structure.Each technology in the invention is special
Sign, can be with combination of interactions under the premise of not conflicting conflict.
Embodiment is as follows, referring to Fig.1, a kind of self-lubricating suture for being easy to take out stitches, including syringe needle 1, the syringe needle 1
Right side is equipped with tip, further includes wire body 3, the wire body 3 is fixedly connected with the left end of syringe needle 1, the appearance of the wire body 3
Face is coated with self-lubricating coat in use 2.By reducing the coefficient of friction on suture surface in the surface of suture addition lubricant coating,
So that its sliding friction is smaller when taking out stitches, it is easier to take out stitches, and the pain to caused by is smaller.
It is further used as preferred embodiment, the material of the wire body 3 is ti-ni shape memory alloy.Titanium nickel is used as a result,
Memorial alloy can be restored to the characteristic of straightened condition automatically using it, can accelerate the healing of wound.
It is further used as preferred embodiment, the material of the self-lubricating coat in use 2 is hydrophilic material.Hydrophily is
Refer to a kind of property showed when water and the surface of solids contact.When liquid and solid contact, liquid can be along the surface of solids
Extension, this phenomenon are known as the infiltration phenomenon of liquid and solid.When its good hydrophilic property, effect of impregnation is obvious, macro manifestations
It is spread out on a solid surface for liquid.Water wetted material can reduce absorption of the surface to cell and protein etc., so as to reduce
Resistance when it is moved, shows lubricity.Specifically, water wetted material can be polyvinylpyrrolidone.It is tested through experiment,
After the PVP hydrophilic coating is attached to PU catheter surface, coefficient of friction is reduced to 0.05 by 1.01, and coating does not take off through 15 frictions
It falls, adhesive force is good, and Hydrophilic lubrication significantly improves.
It is further used as preferred embodiment, the material of the self-lubricating coat in use 2 is Teflon.It is applied using Teflon
Material is used as self-lubricating coat in use, and skin-friction coefficient is low, the high lubricating effect played, and manufacture craft is mature, it is easy to accomplish.
It is further used as preferred embodiment, the syringe needle 1 is gradually reduced after becoming larger from tip.The point of syringe needle
The needs in puncture are brought out, area of section is necessarily made very small, and intensity is weaker, therefore syringe needle is become larger by tip, syringe needle
Intensity can be guaranteed, be gradually reduced by section larger part, convenient for being fixedly connected with wire body.
It is further used as preferred embodiment, the left end of the syringe needle 1 is equipped with blind hole, and the wire body 3 is inserted into blind
It is fitted tightly on together in hole and with the internal perisporium of blind hole.Needle body can be by way of tightly inserting in fixed blind hole as a result, needle
Body is convenient for linking together with syringe needle.
The better embodiment of the utility model is illustrated above, but the invention be not limited to it is described
Embodiment, those skilled in the art can also make various equivalent changes without departing from the spirit of the present invention
Type or replacement, these equivalent variation or replacement are all included in the scope defined by the claims of the present application.
