Description

A kind of tension suture wound protector

Technical field

This utility model relates to technical field of medical instruments, specifically, is a kind of tension suture Wound protection Device.

Background technology

Tension suture is a kind of suture way conventional in surgical operation especially abdominal surgery, multiplex If in otch both sides distant cause the involutory difficulty of otch carry out ordinary sewing will occur disruption of wound trouble Person, subtract a suture due to the tension force that bears relatively big, skin is as will be cut without suitable protective measure below Property damage.

During for current tension suture, particularly in the face of the situation that wound both sides skin tension is excessive, typically stitch Zygonema pulling force is inadequate, needs to carry out tension suture.After stitching, remove after needing 14 days.And existing subtracting opens Stitching has the disadvantage that

First, without protecting the device of wound targetedly, and on the market without the product of dedicated sales, clinical During surgical, in order to avoid suture isolates skin, it is common that make one section of rubber tube by oneself and serve as Wound protection dress Put, there is random forming corrugations bigger, easy, shortcoming that protected effect cannot ensure, rubber tube in addition In easily accumulate more dirt and be not easily cleaned, beneficially bacterial reproduction so that the potential threat of infection of incisional wound.

It addition, because rubber tube is being oppressed in position, wound both sides through suture, along with the healing of wound, make Obtain rubber tube pressure and skin is had contention effect, and rubber tube outer peripheral face is without ventilative hole design, rubber pipe range Easily cause wound skin histology downright bad under phase compressing.

Secondly, the both ends of rubber tube are straight otch, on the one hand during wound healing, and its rubber tube two ends The straight otch in portion easily hurts skin histology, on the other hand, during wound healing, and its rubber tube and wound both sides Face directly contacts, and the pressure that rubber tube both ends are born is bigger so that rubber tube poor stability, easy to fall off or Slip.

Furthermore, different patients are different because of body constitution, if some patients use rubber tube to serve as type wound protecting device, Patient of hypersensitivity may be caused, it addition, itself material factors of rubber tube so that rubber tube is at wound site Poor with skin attachement.

In sum, need badly a kind of with strong points, it is possible to prevent skin, reduce with skin contact pressure, The tension suture wound protector that stability is high, stickiness is good, and about this tension suture wound protector Yet there are no report.

Summary of the invention

The purpose of this utility model is to provide a kind of with strong points, it is possible to prevent skin, reduction from connecing with skin The tension suture wound protector that contacting surface pressure, stability are high, stickiness is good.

For achieving the above object, this utility model adopts the technical scheme that:

A kind of tension suture wound protector, described subtract a wound protector include sewing needle, stitching thread, Silica gel tube；Described sewing needle includes needle point, needle body, backshank；Connect at described backshank and have stitching thread；Institute State and on stitching thread, be cased with silica gel tube；Described silica gel tube is hollow pipe；The outer peripheral face of described silica gel tube is provided with hole Hole, its hole externally communicates with the external world, internally communicates with the hollow channel of silica gel tube；Described silica gel tube Two ends are provided with tubaeform base.

Described hole is in the W-shaped arrangement of outer peripheral face of silica gel tube.

The a length of 2-4cm of described needle point.

The a length of 5-7cm of described needle body.

The outer face diameter of described base is more than the diameter of silica gel tube.

Described stitching thread includes silkworm silk stitching thread, polypropylene suture, rustless steel stitching thread.

Described hole is rounded.

The a length of 9-15cm of described sewing needle, and the tangent line angle at sewing needle two ends is 37-39 degree.

This utility model advantage is:

1, a kind of tension suture wound protector of the present utility model, silica gel tube is enclosed within stitching thread, serves as The effect of neonychium, it is possible to avoid stitching thread to isolate skin；

2, silica gel tube profile is circular arc, and stickiness is good, it is possible to be fitted in well on wound, stability Good, be not likely to produce come off, the safety problem such as slippage；

3, silica gel tube is provided with hole, good permeability, reduces skin compression, the beneficially blood of wound local Pipe unimpeded, it is to avoid cutaneous necrosis, hole is W-shaped, and this is corresponding with the position of suture wound；

4, silica gel tube two ends are provided with tubaeform base, big with contact skin area, reduce silica gel tube and skin The pressure of skin contact surface, strengthens comfort；

5, silica gel tube uses antianaphylaxis material, transparent, antiallergic, single use, clean hygiene；

6, silica gel tube is placed in wound surface and has been effectively isolated the pollutant such as fine powder, dust, and can be by office The temperature of portion's skin and humidity are maintained at suitable scope, greatly reduce the infection rate of wound, shorten wound Mouth healing time；

7, silica gel tube is by involutory neatly for wound both sides skin, and granulation tissue well-grown, scar tissue is tiny Or inconspicuous, can effectively reduce wound both sides skin tension, promote wound skin para-position healing, reduce cicatrix Generation.
