Abstract

The utility model provides a skin grafting baling stitching instrument used in surgery operations, comprising a suture needle, a closing thread and a fixing-line device. The utility model is characterized in that the fixing-line device is a holding latch provided with a threading hole and a fixing-line groove which are penetrated up and down through the entire fixing-line device, the fixing-line groove is provided with a groove at the side wall of the threading hole to extend outward from broad to narrow, the gradual-entering type design is employed till the width of the groove is smaller than the thickness of the closing thread for chucking, one end of the closing thread is fixed on the lower end of the fixing-line device and the other end of the closing thread is connected with the suture needle, the suture needle passes out from the wound or cuticular border when in suturing, then penetrates from the threading hole from bottom to top, the closing thread is tightly pulled, the closing thread can take advantage of an opportunity to enter the fixing-line groove from the threading hole and reach the narrowest portion of the fixing-line groove to chuck, thereby the closing thread cannot easily slide out. The skin grafting baling stitching instrument can effectively suture, avoids from knotting, reduces the disconnecting, suturing and knotting time, and is reliable in fixing and convenient for adjusting.

Description

A kind of operation skin grafting packing stitching instrument

Technical field

This utility model relates to surgical operating instrument, is specifically related to a kind of operation stitching apparatus.

Background technology

The application that skin graft is transplanted starts from 19th century posterior lobe, in the treatment of plastic surgery and burns unit, play a part very important, usually can be divided into split-thickness skin graft (sword is thick, Bao Zhonghou, thick in thick, thick in general), full thickness skin graft by skin graft thickness and contain three kinds of subdermal vascular plexus free skin grafts from the body skin graft, wherein the split thickness skin graft survival is easier, therefore approximate again full thickness skin graft is widely used in the plastic surgery at aspects such as contractility, wearability, color changes.

The skin-grafting technology of split-thickness skin graft and full thickness skin graft is identical, and three steps are arranged: 1, wound surface hemostasis, 2, skin graft fixes, 3, wrapping and braking.In order to improve the survival rate of transplanting skin graft, on abundant hemostatic basis, carry out fixing reliably wrapping and braking, the packing bandaging strapping is the most reliable method, is applicable to being distinguished of whole skin graft transplanting of fresh wound surface, and its concrete grammar is as follows: interrupted suture, stay long line to use for packing, with Cotton Gossypii or the soft crocus cloth of matter, successively be deposited on the skin graft of transplanting, reach and intersect the packing wrapping behind the suitable thickness.

Needs carry out larger area packing skin grafting, and the whole surgery time often needed 2-4 individual hour, even longer, and operation for a long time at first, makes wound surface open-assembly time prolongation, to the vigor and the certain influence of survival generation of skin graft; Secondly, increase the traumatic infection probability; The 3rd, expend a large amount of energy of operative doctor, especially connect the platform operation, the doctor is too tired, influences surgical effect; Four, increase surgery cost.Therefore how to shorten operating time, will find by practice and investigation, in the whole surgery process for doctor and patient brings great benefit, the stitching of skin graft often expends the plenty of time, and therefore a kind of suture way more efficiently will bring great convenience for operator.

Summary of the invention:

Be assurance surgical effect, quality, and shorten operating time as much as possible that this utility model provides a kind of and can effectively sew up, avoids knotting, fixing operation reliably skin-grafting packing suture.

The technical scheme that its technical problem that solves this utility model adopts is:

A kind of operation skin grafting packing stitching instrument, it comprises sewing needle, suture and fixing-line device three parts.Described fixing-line device is one to have the clamp of through wires hole and cable clamping interface, through wires hole and the whole fixing-line device of cable clamping interface up/down perforation, and cable clamping interface is slotted from the through wires hole sidewall, stretch out to narrow by wide, take to be fade-in the formula design,, can tighten suture until the thickness of groove width less than suture.One end of suture is fixed on the fixing-line device lower end, and the suture other end is connected with sewing needle.When sewing up, sewing needle passes from wound or skin edge like this, after penetrating from bottom to top from through wires hole again, and the tension suture, suture can be taken advantage of a situation from through wires hole and be entered in the cable clamping interface, to the narrowest place of cable clamping interface chucking, makes it be difficult for skidding off.

In order more effectively to tighten suture, increase the frictional force of suture and cable clamping interface wall, the longitudinal section of cable clamping interface can be designed to shaped form.More excellent form is Z type or S type.

Remarkable advantage of the present utility model is:

1, after skin graft and surrounding tissue are sewed up, only needs sewing needle is penetrated by through wires hole, suture is drawn in the cable clamping interface chucking get final product, need not knotting, save the plenty of time.

2, in skin grafting, after stitching finishes, if find that hemostasis is not thorough, or under the skin graft blood clot is arranged, and can directly suture be pulled out in cable clamping interface, unclamp and get final product, compare with traditional method, reduced the time of taking out stitches, sew up, tiing a knot, avoided the trouble of inconvenient adjustment.

3, suture length unanimity, the trouble that has caused because of pack thread is uneven when having avoided knotting.

The specific embodiment

Describe structure of the present utility model and use in detail below in conjunction with accompanying drawing:

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, this skin grafting packing stitching instrument is made up of sewing needle 3, suture 2 and fixing-line device 1 three parts.Wherein fixing-line device 1 is designed to a clamp form that has through wires hole 11 and a cable clamping interface 12, through wires hole 11 and the whole fixing-line device of cable clamping interface 12 up/down perforations, cable clamping interface 12 is the sidewall flutings from through wires hole 11, and take to be fade-in the formula design, groove width is to be stretched out to narrow by wide, until the thickness of groove width less than suture, to tighten suture be purpose to reach.And the longitudinal section preferred design of cable clamping interface becomes the S type, to increase clamping force.One end of suture 2 is fixed on the lower end of fixing-line device 1, and suture 2 other ends then are connected with sewing needle 3.Fixing-line device adopts materials such as metal, plastics or silica gel, can accomplish size about 5mmz.

The occupation mode of this stiching instrument in skin grafting is as follows, referring to Fig. 6:

(1) loosen earlier or removal lesion tissue, thoroughly hemostasis forms wound surface and waits to make skin graft;

(2) follow bark fetching;

(3) then with first stiching instrument by surrounding tissue 4 inserting needles, pass from transplanting skin graft 5, and sewing needle penetrates back (seeing Fig. 6 A) from bottom to top from through wires hole, strain suture then, suture can be taken advantage of a situation from through wires hole and be entered in the cable clamping interface, to the narrowest place of cable clamping interface, and tension (seeing Fig. 6 B);

(4) then sew up the whole periphery of skin grafted wounds in order, the tension suture;

(5) remove sewing needle;

(6) separated time;

(7) with at the bottom of oily yarn or the antibiotic gauze pad, broken yarn is piled into bag;

(8) Fig. 6 C is seen in intersection pressurization packing.
