Abstract
The utility model relates to a suturing device and a nickel-titanium memory alloy suturing nail belonging to a surgical instrument (medical instrument). The suturing nail makes use of the restoring force generated by the nickel-titanium memory alloy under the function of body temperature to tightly pull a skin breach and enable sutured skin seams in an outer turning shape. The suturing device can nail the suturing nail into the skin. The suturing nail is made of nickel-titanium memory alloy and a nail body is in an arc shape. The suturing device is composed of a a handle, a handle connecting rod, a return spring plate, a pushing nail rod, a clamping nail plate and a nail storing box. The head part of the pushing nail rod is provided with a clamping nail slot and the nail body can be kept in a straight shape to be nailed into the skin. The inner part of the nail storing box is provided with a nail containing slot and nail guiding slot. The outer wall of the nail containing box is marked with scale lines used for guiding suture.
Description
One, this utility model belongs to a kind of operating theater instruments.(medical apparatus and instruments)
Two, novelty of the present utility model.
1, niti-shaped memorial alloy belongs to a kind of novel functional living being material, does not still have report with its suturing nail as skin breach (trauma wound and scalpel edge).
2, this suturing nail is an arc, and is different with the shape of the stainless steel nail of present use.
3, because the shape difference of suturing nail, so the structure of stiching instrument is also inequality.
Three, design the purpose of this utility model: be used to sew up the skin breach that causes by wound and operation.
Four, content of the present utility model
1, Ultimum Ti as a kind of novel Biofunctional material China use existing 10 surplus year.Range of application relates to fields such as Orthopeadic Surgery, department of cerebral surgery, cardiovascular surgery, thoracic surgery, Urology Surgery, all obtains promising result.
2, this suturing nail is that the restoring force that utilizes Ultimum Ti to be returned to original form at a certain temperature to be produced is drawn the skin breach over to one's side and that it is turned up is involutory tight.(restoring force is not a restoring force, and its strength surpasses metallic spring power, so can do the memorial alloy nail more tinyly.)
3, the design of suturing nail
Make diameter 0.3mm, 0.4mm, three kinds of specifications of 0.5mm with the Ultimum Ti silk; The long 3mm of nail foot, three kinds of specifications of 5mm, 8mm.Nail height 10mm, three kinds of specifications of 12mm, 14mm; Nail is as arc (1/4 arc left and right sides radius can be calculated by nail height degree), and the deformation temperature of nail is lower than 0 ℃, and recovery temperature is lower than 20 ℃.During use the nail body being straightend the back hammers into the bipod of nail in the skin.
4, the design of stiching instrument
Form by parts such as handle, handle and connecting rod, handle reseting spring leaf, ejector pin bar, bail sheet, storage nail boxes.Characteristics are: 1. can be continuously for 20-40 piece of nail; 2. can use the suturing nail of different size by the length of changing storage nail box and adjusting bail sheet; 3. the head of ejector pin bar has a bail groove, can be straight nail body card; 4. the outer wall of storage nail box indicates dimension line in order to instruct stitching.(not drawing among the figure)
Five, advantage of the present utility model
1, simplifies the stitching program, shorten suture time; Easy to learn, except using, can also make vast country doctor and open-air staff also can grasp the suturing skill of wound for hospital, clinic.
Most at present skin breaches all adopt the silk suture method: by an instrument nurse line is through on the special-purpose skin closure pin earlier, sew up by a doctor, another doctor is responsible for stitching thread is tied a knot, and the drawing of skin breach is tightened, and then unnecessary suture wire scissors is removed.After finishing, also to snug the skin breach wound suture, to tightly with tweezers.Operate and loaded down with trivial detailsly can not sew up without specialized training.Use stiching instrument just much more simply, as long as it is just passable to hold fixed handle.
2, can improve suture quality, reduce cicatrization.1. this suturing nail proves that through clinic trial its performance obviously is better than stitching thread and stainless steel nail.Stainless steel nail is thicker, can not produce pulling force, and shape is identical with staple, so can not can not make the good tension of skin breach the edge of skin breach be valgoid.Memorial alloy nail can produce bigger restoring force under the effect of body temperature, the skin breach is drawn over to one's side involutory, and it is involutory that the cuved nail body can make fissure of skin mouth edge be valgoid.(skin of human body its edge occurs behind the breach and will bounce back and be valgoid, helps hemostasis.Need after breach is sewed up in the skin edge that turns over pull out tightly, otherwise breach will be because of the involutory bad healing that influences, and can form bigger cicatrix.)
2. to be tied to form an annular fast knot behind the silk suture, make that skin forms cicatrix because of ischemic necrosis under the suture, how many road cicatrixes just be arranged so sew up how many pins.Suturing nail is the other than ring type structure, cutaneous necrosis and cicatrix can not occur.
3. the biocompatibility of Ultimum Ti is better than silk thread and rustless steel, and is little to tissue irritation, helps wound healing.Silk thread has intensive rejection as a kind of organic compound human body to it, sews up back skin redness often takes place, even stitch abscess can occur, influences wound healing.
4. can reduce use cost.Present employed stiching instrument is a disposable product, and price is sewed up a pin and also will be taken more than 100 yuan more than hundred yuan.And this utility model can be reused, and only receives the expense of suturing nail at every turn.

Each component names:
1, handle 6, storage nail box
2, handle reseting spring leaf 7, bail groove
3, handle and connecting rod 8, binding groove
4, ejector pin bar 9, guide nail slot
5, bail sheet 10, suturing nail
Seven, the operation principle of accompanying drawings stiching instrument
1, suturing nail is packed in the binding groove (8), in Figure 10,13, can show the position of suturing nail (10) in the binding groove.The rear portion of binding groove has spring leaf (not drawing among the figure) that suturing nail is advanced in the bail groove (7) (Figure 14), makes the nail body keep straight staple to go in the skin.Figure 10,11,12, can show the state of suturing nail in the bail groove
2, hold fixed handle ejector pin bar (4) reach, nail moves forward along guide nail slot (9) with the ejector pin bar in the bail groove, and (Fig. 6,10) will lunge in the skin after nail passes the end opening of guide nail slot.After the head of ejector pin bar passes the end opening of guide nail slot, just nail can eject the bail groove automatically in recovering original arcual process, because the bail groove is very shallow, if there is not the restriction nail of guide nail slot can not stay in the bail groove.
3, back-moving spring (2) can make ejector pin bar (4) get back to original position, and bail groove and binding groove are in same horizontal level, and second piece of nail is pushed in the bail groove, then can carry out having operated the second time.
