技术领域technical field
本发明涉及输卵管复通术手术器具，具体为一种输卵管支撑管。The invention relates to a surgical appliance for fallopian tube reversal, in particular to a fallopian tube support tube.
背景技术Background technique
输卵管结扎术是一种永久性避孕方式，目前国内常用的方法有切开系膜输卵管部分切除结扎法（包括近端包埋及远端旷置），输卵管双折结扎切除法，输卵管压挫结扎法及输卵管伞部切除法，输卵管结扎手术途径有经腹部，阴道前、后穹窿及腹股沟部，目前提倡以腹部手术为主。此手术只为决定不再有生育需求的女性所做，不适用于暂时性避孕。Tubal ligation is a permanent method of contraception. At present, the commonly used methods in China include partial resection and ligation of the fallopian tube (including proximal embedding and distal exclusion), double-fold ligation and resection of the fallopian tube, and tubal depression ligation. Method and tubal umbrella resection method, tubal ligation surgical approach through the abdomen, anterior and posterior vaginal fornix and inguinal, currently advocated mainly abdominal surgery. This procedure is only done for women who have decided that they no longer want to have children and is not suitable for temporary contraception.
但随着国家二胎政策的开放，越来越多的夫妇决定生育二胎，但已做输卵管结扎术成为阻碍女性再次生育的阻碍。因此输卵管结扎后的复通问题也逐渐成了一个社会问题。通常来说结扎手术会先用丝线将输卵管绑住，切断并用电烧灼破坏内径及止血，甚至将整条输卵管全切除。因此输卵管结扎后是否能复通，还要看首次结扎手术范围的大小。医师在做输卵管结扎复通手术时，先将结扎处的两端输卵管切除，再将两侧的输卵管管腔对齐后，用很细的缝线对缝4至8针。However, with the opening of the national second-child policy, more and more couples decide to have a second child, but tubal ligation has become an obstacle that prevents women from having another child. Therefore, the recanalization problem after tubal ligation has gradually become a social problem. Generally speaking, the ligation operation will first tie the fallopian tube with silk thread, cut off and use electric cautery to destroy the inner diameter and stop bleeding, or even remove the entire fallopian tube. Therefore, whether the fallopian tube can be recanalized after ligation depends on the size of the first ligation operation. When the doctor performs tubal ligation and recanalization, the two ends of the fallopian tubes at the ligation site are first excised, and then the lumens of the fallopian tubes on both sides are aligned, and 4 to 8 stitches are stitched against each other with very thin sutures.
现有技术的问题是：为了保证输卵管缝合后能正常愈合，需要使输卵管的粘膜对合粘膜，这时就需要一个支撑，保证术中以及术后缝合后的输卵管能始终保持对合，但现有技术中尚无针对输卵管复通术设置的支撑装置，多暂时使用七号丝线或导丝，二者均并不是专门针对输卵管复通术设置的，所以存在术中丝线和导丝不易导入，术后丝线或导丝容易脱落以及感染等问题。The problem of the prior art is: in order to ensure the normal healing of the fallopian tubes after suturing, it is necessary to make the mucosa of the fallopian tubes close to the mucosa. At this time, a support is needed to ensure that the fallopian tubes can always be closed during and after the operation. In the existing technology, there is no support device for fallopian tube reversal, and the No. 7 silk thread or guide wire is used temporarily. Both of them are not specially set up for fallopian tube reversal, so it is difficult to introduce the silk thread and guide wire during the operation. Postoperative silk thread or guide wire is easy to fall off and infection and other problems.
发明内容Contents of the invention
本发明为了解决现有输卵管支撑装置术中不易导入，术后容易脱落的问题，意在提供一种易导入不易脱落的输卵管支撑管。In order to solve the problem that the existing fallopian tube support device is difficult to introduce during operation and easy to fall off after operation, the present invention aims to provide a fallopian tube support tube that is easy to introduce and not easy to fall off.
本发明提供基础方案一：输卵管支撑管，其中，包括支撑管本体与硬质导丝，支撑管本体为胶原蛋白材质的软管支撑管，支撑管本体具有中空腔体，中空腔体一端开口，硬质导丝导入中空腔体中，支撑管本体为线状，硬质导丝抽出中空腔体后，支撑管本体的两端为卷曲状。The present invention provides basic solution 1: fallopian tube support tube, which includes a support tube body and a hard guide wire, the support tube body is a hose support tube made of collagen, the support tube body has a hollow cavity, and one end of the hollow cavity is open. The hard guide wire is introduced into the hollow cavity, and the main body of the support tube is linear. After the hard guide wire is pulled out of the hollow cavity, both ends of the support tube body are curled.
工作原理：导入输卵管支撑管时，硬质导丝位于支撑管本体内的中空腔体中，这使整个输卵管支撑管具有一定的刚性，便于输卵管支撑管导入输卵管，导入完成后抽出硬质导丝，失去硬质导丝的支撑后支撑管本体在自身应力的作用下，支撑管本体的两端自然弯曲，避免输卵管支撑管从输卵管中脱落。Working principle: When the fallopian tube support tube is introduced, the hard guide wire is located in the hollow cavity of the support tube body, which makes the whole fallopian tube support tube have a certain rigidity, which is convenient for the fallopian tube support tube to be introduced into the fallopian tube. After the introduction is completed, the hard guide wire is pulled out After losing the support of the hard guide wire, the two ends of the support tube body are naturally bent under the action of its own stress, so as to prevent the fallopian tube support tube from falling off from the fallopian tube.
有益效果：输卵管支撑管在硬质导丝的配合下具有两种状态，同时解决了过软的支撑装置不易导入输卵管，和导入后支撑装置容易脱落的问题。由于采用胶原蛋白材质的软管，所以一段时间后，输卵管支撑管会自动分解并被人体吸收，避免为病患取出输卵管支撑管而进行的二次手术，降低了病人的痛苦和感染的可能性。Beneficial effects: the fallopian tube support tube has two states under the cooperation of the hard guide wire, and at the same time solves the problems that the support device that is too soft is not easy to be introduced into the fallopian tube, and the support device is easy to fall off after being introduced. Due to the use of collagen tubes, the fallopian tube support tube will automatically decompose and be absorbed by the body after a period of time, avoiding secondary surgery for patients to remove the fallopian tube support tube, reducing the patient's pain and the possibility of infection .
基础方案二：输卵管支撑管，包括支撑管本体，支撑管本体包括支撑内管、外管、隔绝塞以及弹性条，支撑内管注满填充液，支撑内管固定于外管内，支撑内管的管壁上设置有连通外管的连通孔，连通孔由隔绝塞封堵，隔绝塞由石蜡制成；外管内设有石蜡封堵块，外管由石蜡封堵块分隔为空腔与封堵腔，连通孔位于封堵腔的腔壁上，封堵腔内设置有软囊，软囊内填充有乙醇；外管的两端的管壁上均贴有弹性条。Basic plan two: fallopian tube support tube, including the support tube body, the support tube body includes the support inner tube, outer tube, isolation plug and elastic strip, the support inner tube is filled with filling fluid, the support inner tube is fixed in the outer tube, and the support inner tube The pipe wall is provided with a communication hole connected to the outer pipe, and the communication hole is blocked by an isolation plug made of paraffin; the outer pipe is provided with a paraffin plug, and the outer pipe is separated into a cavity and a plug by the paraffin plug. cavity, the communicating hole is located on the cavity wall of the blocking cavity, a soft capsule is arranged in the blocking cavity, and the soft capsule is filled with ethanol; the tube walls at both ends of the outer tube are pasted with elastic strips.
工作原理，输卵管支撑管分为两种状态，第一种状态：在支撑内管注满填充液时，由于填充液的充满支撑内管，填充液的张力使得整个支撑内管处于绷直状态，具有一定的弹性的同时也具备一定的刚度，便于在手术时导入输卵管中；第二种状态：导入后需要为了防止输卵管支撑管脱出，借助手术器具将外管的封堵腔内的软囊挤破，使软囊中的乙醇流出，乙醇会逐渐的将由石蜡制成的隔绝塞和封堵块溶解，（石蜡不溶于填充液）支撑内管的填充液会通过封堵腔流入空腔之中，此时由于填充液流出支撑内管所以支撑内管也不再绷紧，输卵管支撑管整体的弹性和刚度有所降低，此时外管两端的弹性条失去了具有刚度的支撑内管的支撑，逐渐弯曲，输卵管支撑管的两端弯曲后能防止支撑管脱出，输卵管完全愈合需要取出支撑管时，使用手术器具破坏输卵管支撑管的端部，使其中的填充液完全流出，输卵管支撑管体积缩小便于术后取出。Working principle, the fallopian tube support tube is divided into two states. The first state: when the support inner tube is filled with filling liquid, the tension of the filling liquid makes the entire support inner tube in a straight state due to the filling liquid filling the support inner tube. It has a certain degree of elasticity and also has a certain degree of rigidity, which is convenient to be introduced into the fallopian tube during the operation; the second state: after the introduction, in order to prevent the prolapse of the fallopian tube support tube, the soft sac in the occluded cavity of the outer tube should be squeezed out with the help of surgical instruments The ethanol in the soft capsule will flow out, and the ethanol will gradually dissolve the isolation plug and block made of paraffin, (paraffin is insoluble in the filling liquid) and the filling liquid supporting the inner tube will flow into the cavity through the sealing cavity At this time, because the filling fluid flows out of the supporting inner tube, the supporting inner tube is no longer tight, and the overall elasticity and stiffness of the fallopian tube supporting tube are reduced. At this time, the elastic strips at both ends of the outer tube lose the support of the rigid inner tube. , gradually bent, the two ends of the fallopian tube support tube are bent to prevent the support tube from prolapse. When the fallopian tube is completely healed and the support tube needs to be taken out, use surgical instruments to destroy the end of the fallopian tube support tube, so that the filling fluid in it can flow out completely. The volume of the fallopian tube support tube Shrunken for easy removal after surgery.
有益效果：1.基础方案一中需要导入硬质导丝，由于输卵管的管径较小，所以硬质导丝需要细至2~4㎜的同时还需要具备使支撑管本体两端绷直的刚度。这对于硬质导丝的材质提出了较高的要求，无疑提高了制造难度和制造成本。基础方案二采用填充液注入使支撑管本体绷直的方式，该结构仅仅对支撑内管的材质作出了韧性要求，只要有足够的韧性，注入液体后在张力的作用下都会具备一定的刚度，而在现有技术中有很多用于医疗的高分子材料都具备足够的韧性。所以基础方案二制造难度低，对材质的要求较低，成本投入较低。Beneficial effects: 1. In the basic plan 1, a hard guide wire needs to be introduced. Since the diameter of the fallopian tube is small, the hard guide wire needs to be as thin as 2-4 mm and at the same time, it is necessary to have the two ends of the support tube body straighten. stiffness. This puts higher requirements on the material of the hard guide wire, which undoubtedly increases the manufacturing difficulty and cost. The second basic plan adopts the way of filling liquid injection to make the support tube body straight. This structure only requires the toughness of the material of the support inner tube. As long as there is enough toughness, after the liquid is injected, it will have a certain stiffness under the action of tension. In the prior art, many polymer materials used in medical treatment possess sufficient toughness. Therefore, the basic plan 2 is less difficult to manufacture, has lower requirements on materials, and lower cost input.
2.在需要取出输卵管支撑管时，可以放出填充液，使整体的管径进一步缩小便于取出。2. When the fallopian tube support tube needs to be taken out, the filling fluid can be released to further reduce the overall tube diameter for easy removal.
3.放置在输卵管内时，由于本方案中具有填充液，输卵管支撑管整体较为柔软，支撑管不会破坏输卵管，更适于输卵管的愈合。3. When placed in the fallopian tube, because of the filling fluid in this solution, the fallopian tube support tube is relatively soft as a whole, and the support tube will not damage the fallopian tube, and is more suitable for the healing of the fallopian tube.
基础方案一和基础方案二的共同的发明点在于均具备两种状态，较硬的状态和较软状态，并且均采用从支撑管本体内的中空腔体中抽出物质，从而使支撑管本体刚度发生变化的方式。The common invention of the basic scheme 1 and the basic scheme 2 is that they both have two states, a harder state and a softer state, and both use the method of extracting material from the hollow cavity in the support tube body, so that the rigidity of the support tube body way of change.
方案二：为基础方案二的优选，隔绝塞位于支撑内管的一头为圆台状。有益效果：支撑内管注满填充液，所以在支撑内管内具有较强的压强，为了避免隔绝塞被冲开，所以将隔绝塞位于支撑内管的一头设置为圆台状，压强会使隔绝塞与支撑内管的内壁贴合的更加紧密。Option 2: Based on the optimization of Option 2, the isolation plug is located at one end of the supporting inner tube and is in the shape of a truncated cone. Beneficial effects: the support inner tube is filled with filling liquid, so there is a strong pressure in the support inner tube, in order to avoid the isolation plug from being washed away, so the isolation plug is set at one end of the support inner tube in a circular frustum shape, and the pressure will make the isolation plug It fits more closely with the inner wall of the supporting inner tube.
方案三：为方案二的优选，支撑内管与外管均为聚氨酯材质。有益效果：聚氨酯材质广泛应用于医用领域且具备较佳的弹性。Option 3: For the optimization of Option 2, the supporting inner tube and outer tube are made of polyurethane. Beneficial effect: the polyurethane material is widely used in the medical field and has good elasticity.
方案四：为方案三的优选，弹性条贴于外管的内壁上。有益效果：相比贴于外管外壁，贴于外管的内壁能减小支撑管本体的管径。Option 4: For the optimization of Option 3, the elastic strip is attached to the inner wall of the outer tube. Beneficial effects: compared with sticking to the outer wall of the outer tube, sticking to the inner wall of the outer tube can reduce the pipe diameter of the support tube body.
方案五：为方案四的优选，内管内的填充液为生理盐水或水。有益效果：生理盐水或水都对人体无害，可由人体吸收或者自然的排出体外，增加了本方案使用过程中的安全性。Scheme five: it is the optimization of scheme four, the filling liquid in the inner tube is physiological saline or water. Beneficial effects: physiological saline or water are harmless to the human body, can be absorbed by the human body or excreted naturally, which increases the safety during the use of the solution.

工作原理，输卵管支撑管分为两种状态，第一种状态：在支撑内管1注满水时，由于支撑内管1内充满水，水的张力使得整个支撑内管1处于绷直状态，具有一定的弹性的同时也具备一定的刚度，便于在手术时导入输卵管中；第二种状态：导入后需要为了防止输卵管支撑管脱出，借助手术器具将外管2的封堵腔22内的软囊6挤破，使软囊6中的乙醇流出，乙醇会逐渐的将由石蜡制成的隔绝塞3和封堵块5溶解，支撑内管1的水会通过封堵腔22流入空腔21之中，此时由于水流出支撑内管1所以支撑内管1也不再绷紧，输卵管支撑管整体的弹性和刚度有所降低，此时外管2两端的弹性条4失去了具有刚度的支撑内管1的支撑，逐渐弯曲，输卵管支撑管的两端弯曲后能防止支撑管脱出，输卵管完全愈合需要取出支撑管时，使用手术器具破坏输卵管支撑管的端部，使其中的水完全流出，输卵管支撑管的管径进一步缩小便于术后取出。Working principle, the fallopian tube support tube is divided into two states, the first state: when the support inner tube 1 is filled with water, because the support inner tube 1 is filled with water, the tension of the water makes the whole support inner tube 1 in a stretched state, It has a certain degree of elasticity and also has a certain degree of rigidity, so that it can be easily introduced into the fallopian tube during operation; the second state: after introduction, in order to prevent the prolapse of the fallopian tube support tube, the soft tube in the plugging cavity 22 of the outer tube 2 needs to be removed with the help of surgical instruments. The capsule 6 is broken, so that the ethanol in the soft capsule 6 flows out, and the ethanol will gradually dissolve the isolation plug 3 and the blocking block 5 made of paraffin, and the water supporting the inner tube 1 will flow into the cavity 21 through the blocking cavity 22 At this time, because the water flows out of the support inner tube 1, the support inner tube 1 is no longer tight, and the overall elasticity and stiffness of the fallopian tube support tube are reduced. At this time, the elastic strips 4 at both ends of the outer tube 2 lose the support with stiffness. The support of the inner tube 1 is gradually bent, and the two ends of the fallopian tube support tube are bent to prevent the support tube from prolapse. When the fallopian tube is completely healed and the support tube needs to be taken out, use surgical instruments to destroy the end of the fallopian tube support tube, so that the water in it can flow out completely. The diameter of the fallopian tube support tube is further reduced to facilitate postoperative removal.
本实施例的优化的使用方法：步骤1，降低输卵管的温度至5~10℃；The optimized usage method of this embodiment: Step 1, lower the temperature of the oviduct to 5-10°C;
步骤2，使输卵管支撑管保持线形；Step 2, keep the fallopian tube support tube linear;
步骤3，使支撑内管1的水结冰；Step 3, freezing the water supporting the inner pipe 1;
步骤4，将输卵管支撑管导入输卵管中；Step 4, introducing the fallopian tube support tube into the fallopian tube;
步骤5，粉碎软囊6。Step 5, crushing the soft capsule 6 .
该优化的使用方法能使支撑内管的结冰后，这会使输卵管支撑管整体的硬度更高，更容易导入输卵管中，手术完成后人体的温度会使支撑内管内的水慢慢融化，支撑内管慢慢的恢复弹性。This optimized usage method can make the support inner tube freeze, which will make the overall hardness of the fallopian tube support tube higher and easier to guide into the fallopian tube. After the operation is completed, the temperature of the human body will slowly melt the water in the support inner tube. Support the inner tube to slowly recover its elasticity.
