Abstract

The utility model relates to the health care field and particularly discloses an embedded type skin plasma skin-grafting needle. The embedded type skin plasma skin-grafting needle comprises a needle cylinder and a needle core, wherein the front ends of the needle cylinder and the needle core are ellipse faces in parallel; the ellipse faces of the needle cylinder and the needle core can exactly be meshed; a needle cylinder end is provided with a needle feeding depth line which is perpendicular to the needle body direction; the needle cylinder on the needle feeding depth line far from the needle point is provided with an L-shaped opening; the tail part of the needle cylinder is provided with a tail cap; the tail part of the needle core is provided with a tail cap; one end of the tail cap of the needle cylinder is provided with a concave groove, and one end of the needle core is provided with a convex groove; and the convex groove and concave groove can be completely meshed. With the adoption of the embedded type skin pulping skin-grafting needle, the autologous skin plasma can be exactly transplanted under the skin wound granulation tissue; the operation method is simple and in favor of the survival of the skin plasma at the wound surface; and furthermore, secondary injury on the skin plasma is little.

Description

Embedded latex graft needle

Technical field

This utility model relates to a kind of embedded latex skin-grafting device, is particularly useful for the subcutaneous transplantation operation of skin.

Background technology

Self-skin transplant is to repair the most frequently used method of deep burn wound, and the form when transplanting according to skin graft can be divided into skin graftings such as spready hide, netted skin, microparticle skin etc.; Postoperative, autologous skin is in the wound surface survival and epidermis propagation and transfer take place, final complete covering and reparation burn wound.But the granulation wound that forms in some privileged sites burn backs is difficult to cause above method to lose efficacy in its surface survival from the body skin graft.The skin-grafting of embedded latex can with skin histology with the latex form be transplanted under the granulation wound, on the granulation basilar fibers.In this environment, the skin microgranule can obtain the prescribing adequate nutrition material and avoid germ contamination, and survival rate is high, has advantage at the treatment granulation wound.But still there be not latex instrument for transplanting and the technology that embeds granulation tissue that be applicable in the medical apparatus and instruments commonly used at present.

Summary of the invention

Treatment for granulation wound after latex skin-grafting technology is effectively applied to burn; This utility model provides a kind of embedded latex graft needle; This device can be transplanted to the latex fixed point of loading under the granulation tissue through injecting pathway, effectively skin histology is transplanted to ideal position.

According to the technical scheme that this utility model provided, embedded latex graft needle comprises syringe, nook closing member two parts, and said syringe and nook closing member front end are the ellipsoid that is parallel to each other, and the ellipsoid of syringe and nook closing member can accurately agree with.

Said syringe end has the depth of needle line, and is vertical with the needle body direction.Described syringe has " L " shape opening away from the needle point direction more than the depth of needle line.Described syringe afterbody has the tail medicated cap.

Described nook closing member afterbody has the tail medicated cap.Tail medicated cap one end of said syringe has groove, and tail medicated cap one end of said nook closing member has tongue, and tongue and groove can agree with fully.

The beneficial effect of this utility model is, can autologous skin slurry accurately be transplanted under the skin wound granulation tissue, and operation method is simple, help latex and become to live at wound surface, and little to the secondary damage of wound surface.

The specific embodiment

Fig. 1～shown in Figure 2,1. syringe, 2. nook closing member, 3. " L " shape opening, 4. syringe tail medicated cap, 5. nook closing member tail medicated cap, 6. syringe tail medicated cap semi-circular recesses, 7. semicircle tongue, 8. depth of needle line of nook closing member tail medicated cap.

Following embodiment will specify the operational approach of this utility model, but can not be as the qualification to this utility model.

Fig. 1 and Fig. 2 are respectively the plan view and the vertical view of this utility model.The head of syringe 1 and nook closing member 2 has parallel oval needle point, the operation that helps inserting granulation tissue.Depth of needle line 8 is positioned at needle point to be surveyed, in order to the prompting depth of needle." L " shape opening 3 is for loading the inlet of latex tissue.Syringe tail medicated cap 4 and nook closing member tail medicated cap 5 are used for the withdrawing and the injection process of latex tissue, and syringe tail medicated cap semi-circular recesses 6 can guarantee that with the semicircle tongue 7 of nook closing member tail medicated cap the needle point ellipsoid of syringe 1 and nook closing member 2 is parallel.

Before using embedded latex graft needle, the semicircle tongue 7 of syringe tail medicated cap semi-circular recesses 6 and nook closing member tail medicated cap is agreed with, parallel with the needle point ellipsoid that keeps syringe 1 and nook closing member 2, be easy to follow-up embedding operation.During skin grafting, syringe 1 and nook closing member 2 integral body are embedded under the granulation tissue with the direction perpendicular to wound surface, the operator holds the pin position and is syringe 1 outer wall between " L " shape opening 3 and the syringe tail medicated cap 4.Slow inserting needle, and in the inserting needle process, rotate needle body for several times with the direction of parallel wound surface, until depth of needle line 8, explain that needle point arrives subcutaneous suitable skin-grafting position.

After accomplishing the contact pin operation, withdrawing nook closing member tail medicated cap 5 is to needle point to " L " shape opening of nook closing member 2.With the ophthalmology tweezer latex tissue is filled in " L " shape opening 3, the latex volume depends on fixed point skin-grafting density, but can not surpass certain limit, causes pin chamber obstruction in the skin-grafting process.The semicircle tongue 7 of nook closing member tail medicated cap is aimed at tail medicated cap semi-circular recesses 6; Slowly promote nook closing member tail medicated cap 5 to the wound surface direction; Agree with fully until the semicircle tongue 7 of syringe tail medicated cap semi-circular recesses 6 and nook closing member tail medicated cap, the latex that loads is organized injected granulation tissue inside fully.After skin-grafting finished, behind the direction rotation needle body several of needle body with parallel wound surface, integral body was slowly extracted needle body.

With the hard film external anesthetic puncture pin is prototype, surveying along needle point and making the opening of shape near letter " L " apart from needle point 5mm place, as the inlet that loads latex.Semicircle tongue is kept somewhere at the place at nook closing member tail medicated cap, keeps somewhere semi-circular recesses at syringe tail medicated cap place, and two grooves can completely be engaged.When embedding the latex skin grafting; The needle point of graft needle is inserted suitable location under the granulation tissue; The inner solid needle needle point of withdrawing is filled in latex " L " shape open interior to more than " L " shape opening with the ophthalmology tweezer, inwardly promotes inner solid backshank medicated cap; And the semicircle tongue of nook closing member tail medicated cap place indwelling and the semi-circular recesses of syringe tail medicated cap place indwelling are agreed with fully, guarantee that needle point place latex inputs under the granulation tissue fully.
