Abstract
A stitich thread without cutting to tissue for surgical operation is characterized by that it is a special hollow thread and it can be flattened when it is stressed, so not cutting tissue.
Description
Technical field
The present invention relates to a kind of operating theater instruments, be particularly related to a kind of the operation with the structure of medical suture against cutting, this medical suture against cutting can be used for the tension force that has of more crisp internal organs such as human liver, spleen, pancreas, kidney to be sewed up, and reaches the effect that not damaged coincide.
Background technology
At first, the ordinary sewing needlework, the diameter of pin is far longer than the diameter of line, cause line shutoff pinprick fully, the pinprick oozing of blood is very common, and pin will be connected with line in theory, and the diameter of pin can only be greater than line, if can reach pin and the line bore is approaching as far as possible, line just can reach the purpose that prevents the pinprick oozing of blood by the shutoff pinprick.Secondly, suture takes place and cuts and organizes and cause bleeding due to trauma in regular meeting when in the surgical operation practice more crisp internal organs such as liver, spleen, pancreas, kidney being carried out sew application, and suture loses tension force, sews up the situation of failure.And for fear of the generation of this situation, the patient often has a mind to reduce wire-drawing tension, or pad is pressed foreign body between online and the tissue.Make sewing effect imprecise but reduce stitching tension force, pad is pressed the foreign body complex operation, prolongs operating time, increases foreign body reaction, and protects effect imprecise, still may cause cutting at pin hole.If can there be suture initiatively increasing lifting surface area when contacting, just can reduce the probability that suture cuts and organizes keeping reducing pressure under the same tension force with tissue.Once more, suture is pursued smooth surface, and tissue apposition tension force may cause the toe-in slippage when big, sews up failure.If suture elasticity is stronger, its toe-in can tighten up easily, and frictional force strengthens, and is difficult for slippage.If can have needlework comprehensive above-mentioned some, certainly will for the more crisp tissue of quality effectively, safety sews up and create good conditions.According to the data-searching that the inventor carried out, do not find document related to the present invention.
Summary of the invention
The objective of the invention is to, provide a kind of damage little, it is low to cut and organize probability, sews up tension force and controls the structural design of the special suture that toe-in can be urgent easily easily.The tension force that has that is used for more crisp internal organs such as liver, spleen, pancreas, kidney is sewed up, and reaches the effect that not damaged coincide, and can reduce operating difficulty, improves operative effect.Adopt the needlework outward appearance and the needlework basically identical commonly used of this method preparation, do not change patient's operating habit, simple in structure, easy to use.
Realize that the technical solution that above-mentioned purpose is taked is: a kind of medical suture against cutting, comprise a sewing needle and stitching thread, the afterbody of sewing needle has the needlework connecting portion, it is characterized in that, the end that described stitching thread is connected with sewing needle is by carefully chap gradually, and form successive solid section, changeover portion and section is used in hollow anti-cutting, solid section is fixedly connected to form the needlework connecting portion with the suture needle afterbody.
The external diameter of the internal diameter of above-mentioned needlework connecting portion and solid section is complementary.
Sewing needle can be circular arc, straight shape or other shape, and the length of changeover portion is 2cm.Described hollow anti-cutting uses the diameter of section and the maximum gauge of sewing needle to equate.
Medical suture against cutting of the present invention, because the line of sewing needle and stitching thread connecting portion footpath is solid carefully, line embedded suture Aculeata is effectively connected, thereafter stitching thread increases thick gradually and becomes hollow, use section to equate with the maximum gauge of sewing needle until hollow anti-cutting, effectively shutoff is sewed up pinprick and is prevented oozing of blood.So both guaranteed that sewing needle closely was connected with the stitching thread connecting portion, and made hollow anti-cutting use the diameter of section and sewing needle consistent again.
It is hollow that hollow anti-cutting uses section to be designed to, and makes elasticity increase, and stitching thread can become ellipse or flat with the organizational stress of any direction like this, and increase is long-pending with tissue contact surface automatically, reduces pressure.And linear elasticity is stronger, and thickness is variable, and toe-in tightens up easily, is difficult for slippage.Thereby under bigger stitching tension force, also can effectively avoid tissue cutting damage, the stitching tension force of remaining valid.
The outward appearance of medical suture against cutting of the present invention and needlework basically identical commonly used do not change patient's operating habit, and be simple in structure, easy to use.The needlework simplicity of design is produced easily with existing manufacturing process.And solved and perplex clinical anxious for many years suture to be solved cutting problem, this type of surgical patient of China is numerous, and social benefit and market potential are huge.
Description of drawings
Fig. 1 is a surgical suture against cutting structural representation of the present invention.
Fig. 2 is a hollow anti-line of cut principle schematic of the present invention.
Label among the figure is respectively: 1 is sewing needle, and 2 is the needlework connecting portion, and 3 is solid section, 4 is changeover portion, and 5 are anti-cutting use section, and 6 is the suture material, 7 for suture after sewing up is subjected to organizational stress, and 8 is that the stressed after strain contact area of suture increases, 9 tissues for the suture contact.
The present invention is described in further detail below in conjunction with embodiment that accompanying drawing and inventor provide, so that clearer understanding structure of the present invention, and characteristics of the present invention and advantage.
The specific embodiment
Specific implementation of various details, but should be appreciated that the implementation here only is as an example and illustrates that other scheme that can realize according to principle of the present invention then has a variety of.Clearly, for the people who is familiar with these operation techniques, various variations and modification in category of the present invention will be considered to belong to protection scope of the present invention.
Please refer to Fig. 1,2, medical suture against cutting of the present invention, comprise a sewing needle 1 and stitching thread, the afterbody of sewing needle has needlework connecting portion 2, the end external diameter that described stitching thread is connected with sewing needle 1 is by carefully chap gradually, and form solid section 3, changeover portion 4 continuously and section 5 is used in hollow anti-cutting, fixedly connected with suture needle connecting portion 2 for solid section 3.
The external diameter of the internal diameter of suture needle connecting portion 2 and solid section 3 is complementary.
Described sewing needle 1 can be circular arc, straight shape or other shape as required.
Hollow anti-cutting uses the external diameter of section 5 and the maximum gauge of sewing needle 1 to equate.
For sewing needle 1 and stitching thread are linked into an integrated entity, section 5 is used in the hollow anti-cutting of anti-cutting and stitching line, and transition is for to form solid section 3 than the finedraw line gradually to an end, and the solid section 3 backshank pressing with sewing needle 1 forms an integral body.
Existing eyeless suture needle line for pursuing the needlework external diameter than being the ideal goal of 1:1, is updated the structure of needlework joint portion, but can only be approaching, is difficult to reach.The present invention considers that suture is used hardly to solid section 3 in surgical practice, and in fact solid section 3 had only interconnect function not have suturing, therefore adopts for solid section 3 joining than the bodkin tail of thin bore and sewing needle 1, does not almost have technical difficulty.Pass through the changeover portion 4 of once thick about 2cm gradually solid section 3 back, the suture after the changeover portion 4 is anti-cutting use section 5.The external diameter that sections 5 external diameter and sewing needle 1 are used in the anti-cutting of suture is than being 1:1, thereby the pinprick that stitching thread can well shutoff sewing needle 1 plays the effect of the pinprick oozing of blood that prevents sewing needle 1.Structure of the present invention even can make the medical suture needle line of sewing needle and stitching thread multiple diameter ratio easily reaches the effect of filling pinprick hemostatic.And this can't accomplish with existing technology.
Referring to Fig. 2, the synthetic that uses during stitching thread material 6 employings in the anti-cutting use section 5 are clinical can absorb maybe and can not absorb the suture material manufacturing, its intensity and biocompatibility have been the selection of this area routine, and existing experiment and clinical foundation can prove the safety of relevant suture material.
Hollow anti-cutting uses section 5 to adopt hollow design, be characterized in anti-cutting uses section 5 no matter to be subjected to the function of organization power of what direction, all can be deformed into ellipse accordingly, with Fig. 2 is example, sew up the back suture in the operation and be subjected to organizational stress, the stressed after strain of suture, the contact area of the tissue 9 that suture contact area 8 contacts with suture increases, thereby minimizing pressure, the possibility that minimizing is cut tissue, thus can reach bigger stitching tension force, guarantee curative effect.And operation technique person in the past cuts damaged tissue for fear of suture, control thread tension during knotting, or pad is pressed foreign body.Have only veteran doctor just can reach best sewing effect.
The inventor adopts the surgical suture against cutting of its invention in carrying out hepalobectomy, suture causes the cutting damage at tissue when having avoided common needlework to be used for the stitching of liver section, hemostasis by ligation, and thread tension disappears, and loses the phenomenon of therapeutic effect.Operator is easy to use simultaneously, not be used in the suture underlay and presses foreign body, need not reduce stitching tension force, only just can toe-in is urgent with two knots, and the pinprick oozing of blood is few, and operative speed is fast, and sewing effect is definite.To prevent after the operation that cutting use section 5 remains in the liver section and gets final product, conventional through and through suture hemostasis also can be used medical suture against cutting of the present invention, produces cleaner surgical wound surface.
