Description

[0001]
[Object of the invention]
The present invention is a technique relating to hemostasis that is mainly performed when performing surgical treatment on mammals such as dogs and cats, and in particular, reliably performs hemostasis without damaging delicate tissues in body cavities. A new structure that can reduce the time required for surgery in a short time, and can reliably stop bleeding even for organs that store fat and are slippery and difficult to handle. It is an object of the present invention to provide a ligating band, a novel method for hemostasis and organ extraction using the same, and a method for removing ovaries from a mammal with a novel configuration.
[0002]
[Prior art]
Ovarian hysterectomy in mammals such as dogs and cats is mainly performed for the purpose of effectively controlling indiscriminate breeding, but by performing ovarian hysterectomy before the first estrus, In addition to suppressing mammary gland hyperplasia, it can reduce the incidence of mammary gland tumors by a considerable rate, as well as eliminating the risk of developing ovarian or uterine diseases such as pyometra, intrauterine infection, and ovarian cancer. It has the advantage of being able to be used, is recommended from the viewpoint of animal welfare, and is widely used.
[0003]
In recent years, mammals such as dogs and cats that have been kept like family have a tendency to become obese due to the spread of high nutritional value pet foods and lack of exercise, and to increase the size of breeding dogs. In many cases, there is an excessive accumulation of fat in the abdominal cavity, and cases in which the proper ovarian cord, ovary, and ovarian cord show a single fat mass are increasing.
[0004]
In such over-fertilized dogs, it is difficult to quickly detect the target ovaries and arteries and veins around the uterus, and the thick adipose tissue around the blood vessels is very slippery, and the tightly attached hemostasis It is difficult to obtain sufficient hemostasis because it is difficult to ligate by sending sutures to the deep part even with forceps for use, and there is a risk of damaging the surrounding intestinal tract, bladder, ureter, etc. Therefore, considerable effort and careful attention must be paid, and therefore, the time required for the operation is prolonged, and the burden of anesthesia on the side receiving the operation may be increased. Performing a plurality of operations has resulted in a problem that the surgeon's fatigue increases.
[0005]
Therefore, as a technique for reliably and efficiently performing hemostasis during an operation, for example, a material including metal particles or ceramic on a tube wall grip surface of a surgical clip disclosed in Japanese Patent Application Laid-Open No. 7-194606 has been proposed. By increasing the surface roughness of the tube wall grip surface by applying a coating, it can be firmly fixed when it is attached to a blood vessel. Clips and aneurysm clips "have already been proposed, and as disclosed in Japanese Patent Application Laid-Open No. 10-234738," a device for hemostasis of a vascular anastomosis used for coronary artery bypass surgery " A suction cup body having a flexible channel that can be adsorbed to the wall of the heart while surrounding the coronary artery. A treatment opening is provided for evacuating the air in the flexible channel through an exhaust tube so that the suction edge of the flexible channel is slightly lifted up and closed on the coronary artery without restraining the heart. Means for suppressing bleeding from the incision in the coronary artery incised for anastomosis to such an extent that the operation is hardly affected are sometimes found.
[0006]
However, the former hemostatic clip is intended to stop the bleeding by sandwiching only the blood vessel itself, and can be suitably used for ligating a native ovarian cord or ovarian cord, ovarian artery or vein, or cervix and uterine artery and vein of a mammal. However, it is difficult to perform an efficient operation using this, and the latter hemostatic holding device is also effective for use in temporary and partial hemostasis of the coronary artery in the heart. It is not intended for use in mammalian ovarian hysterectomy, so it is almost impossible to use it to ligate native ovarian cords, ovarian cords, ovarian arteries, or cervix and uterine arteries Therefore, in the prior art, there has been only a resection in which hemostasis with forceps and ligation with a suture have been performed.
[0007]
The present invention, as described above, due to excessive storage of fat in the abdominal cavity of mammals such as domestic dogs and cats in recent years, it becomes very difficult to reliably perform hemostasis by attaching forceps or ligating with sutures, Focusing on the fact that the time required for surgery is longer and the burden on the surgeon is increasing, swift and reliable ligation is performed, and the operation can be completed in a relatively short time, thus ensuring the safety of the operation From the judgment that it is not possible to reduce the burden on doctors as well as to increase it, we started developing and researching quickly, repeating trial and error over a long period of time and many trial productions and experiments, Finally, the present invention has succeeded in realizing a ligation band having a novel structure, a novel hemostasis method using the same, a novel organ extraction method, and a novel mammalian ovary hysterectomy method. In, with examples representative of the present invention shown in the drawings, and specifically described the configuration.
[0008]
Configuration of the Invention
As can be clearly understood from the embodiments of the present invention shown in the drawings, the ligating band of the present invention basically has the following configuration.
In other words, the tourniquet has a predetermined length of the tourniquet, and the stopper meshing portion is continuously formed in the range of the interference in the longitudinal direction of the tourniquet, and the tourniquet extends over the formation range of the stopper meshing portion. A non-slip rib was continuously formed at the appropriate position on the body, and the base end of the tourniquet was formed in a short tunnel shape with an opening on one side and an opening on the other side. A buckle part is formed integrally with a buckle part that forms a locking hook that can undetachably lock the retaining engagement part of the tourniquet body, and the whole is made of a synthetic resin molded product having flexibility. It is a band for ligating as a gist.
[0009]
In other words, the ligating band having this basic configuration has a predetermined length of a tourniquet band, and a locking band in the length direction of the tourniquet band is provided with a retaining engagement portion. Continuously formed, the slip stopper rib was continuously formed at an appropriate position of the tourniquet body over the range of formation of the retaining meshing portion, and the base end of the tourniquet was opened with an insertion port on one side and a delivery port on the other. It has a short tunnel shape and is integrally formed with a buckle part that has a locking hook that can lock the retaining meshing part of the tourniquet pulled in from the tip so that it can not be pulled out. By being made of a flexible synthetic resin molded product, the tourniquet is attached around the target site of the hemostasis of the mammal so as to form a ring, and the end of the tourniquet is inserted into the buckle portion, It can be said that this is a ligating band that can be tightened to stop bleeding.
[0010]
When the ligating band having the basic configuration as described above is shown as a more specific configuration, the width, the thickness, and the length have a tourniquet whose body dimensions are appropriately set. In the range near the center in the width direction of the belt-shaped surface to be inward when forming the annular winding and the interference in the length direction, the side cross-sectional shape cut along the center line from the base end to the tip has a saw-like shape. The retaining meshing part to be formed is continuously formed, and the left and right edges of the tourniquet band extending over the formation range of the retaining meshing part can be engaged in a direction orthogonal to the center line from the base end to the tip of the same band-shaped surface. After forming a non-slip rib continuously, the base end of the tourniquet has a short tunnel shape with an opening on one side and an opening on the other side. Integrated buckle with locking hooks that can lock the retaining mesh of the tourniquet And it will be entirely a ligating band consisted of a synthetic resin molded article having flexibility.
[0011]
More specifically, it has a tourniquet with a width of about 1.5 to 2.5 mm, a thickness of about 1 mm, and a length of about 70 to 80 mm, and a tapered, thin insertion end is formed at the tip. At the same time, in a range near the width direction center of the band-shaped surface to be inward when forming a loop of the tourniquet band and serving as a margin in the length direction, the band is cut along a center line from the base end toward the front end. The cross-sectional shape of the hook is continuously formed with a saw-tooth retaining meshing part, and the left and right edges of the tourniquet band spanning the range of formation of the retaining and locking meshing part are aligned with the center line from the base end to the tip of the same band-shaped surface. A continuous non-slip rib that can be engaged in the orthogonal direction is continuously formed, and the base end of the tourniquet has a short tunnel shape with an opening on one side and an opening on the other side. Locking hook that locks the catching part of the tourniquet body retracted during Formed becomes integrally forming the buckle portion was entirely, stretching has a less flexibility, can be is made of medical synthetic resin molding which does not cause adverse reactions in vivo.
[0012]
The tourniquet is looped around the vicinity of the target cutting site in the body cavity, inserted into the buckle from the tip side, and tightened so that it does not loosen, and the blood flow of the blood vessel tightened in a bundled manner. It has the function of stopping and stopping bleeding.It is wound in a loop around the target cutting site, set to a sufficient length, and has sufficient strength and durability to withstand the traction force enough to stop bleeding in arteries and veins. It is formed of a material having flexibility that can be deformed flexibly so as not to inadvertently damage the tissue, and flexibility such that the excess tip protruding from the buckle after tightening can be cut relatively easily with scissors. The locking engagement part that engages with the locking hook of the buckle part and is locked undetachably shall be formed continuously along the length method over the range of the interference. Must also be a circle The position of the side facing the living body tissue when wound, it should be assumed that the formation of the anti-slip ribs to allow blocking direction sliding substantially perpendicular to the length direction of protrusion or uneven.
[0013]
Further, the tourniquet body penetrates in the thickness direction at one or a plurality of suitable places on the base end side, or at a plurality of suitable places along a length direction of a range of a tightening margin in which the retaining engagement portion is continuously formed. Tightening holes that allow the passage of suture needles and sutures are perforated, or one or more suitable locations on the proximal end, or the length of the fastening margin where the retaining mesh is formed continuously. It is possible to form a notch in the width direction edge and to form a fastening groove capable of locking a suture in a plurality of appropriate places along the length direction.
The retaining meshing portion securely locks the appropriate portion of the tourniquet band inserted through the buckle portion from the distal end within the tightening range to the locking hook formed in the buckle portion and inadvertently removes it. It is engaged so as not to be pulled out, and fulfills the function of being able to maintain the locked state for a long period of time, and is formed continuously on either one of the front and back surfaces of the tourniquet body over the interference range in the longitudinal direction. It should be an uneven portion, and it is desirable that a saw-tooth cross-section having a gentle slope in the insertion direction of the tourniquet body is continuous.
[0014]
The non-slip ribs may cause the tourniquet body wound in a loop around the vicinity of the target cutting site in the body cavity to be inadvertently displaced or slid during and after cutting the target site of the living body. It has the function of biting into living tissue so that it does not form, and it is formed into a protruding rail shape or uneven rail shape on the inner side when it is wound in a loop along the length of the tourniquet The rail shape can be a zigzag shape in a plane, or it can be formed in an uneven tooth shape.
[0015]
When the tip of the tourniquet body that is curved in a ring shape is inserted through the buckle part, it is locked irremovably at the inserted position, and the loop shape of the tourniquet body is maintained as it is. Each time the tip of the body is inserted to increase the insertion amount, it functions to lock the tourniquet irremovably at a position corresponding to the insertion amount each time. The tourniquet must have a structure capable of locking the tourniquet around the periphery in a ring shape with sufficient strength, and an insertion opening that is dimensioned so that the tourniquet can be inserted from the distal end thereof; Having a hook that can be engaged with the retaining meshing portion of the tourniquet between the insertion port and the feeding port, and the locking hook stabilizes the hemostatic state. In order to maintain the tourniquet The it is possible to draw only in the direction to feed from the feeding port, it is desirable in a direction to pull from the insertion port shall certainly engaged so that it can not be pulled back until failure.
[0016]
In addition, the tourniquet body and the buckle are attached in a loop around the living tissue, cut at the target cutting site, and remain in the body even after the stomach is closed. It is desirable to be chamfered so that it does not cause adverse reactions in the living body, such as polyvinyl chloride resin, polyethylene resin, polypropylene resin, fluorine resin, etc. It should be formed from lactic acid-based polymer and other biodegradable synthetic resin molded articles for medical use, so that the cut tissue is gradually cut while maintaining the hemostatic state. It is possible that it will naturally disappear when healing is stopped and hemostasis is no longer needed.
[0017]

[0033]
【The invention's effect】
As described above, according to the ligation band of the present invention, a relatively long and flexible tourniquet body is deformed into a ring shape, and blood vessels such as arteries and veins to be ligated, and Surrounding the surrounding organs, membranes, fats, etc. in a cohesive manner, feeding the end of the tourniquet body into the insertion port of the pillow lock part 3 and tightening it out from the payout port, the buckle locking hook is tightened. By locking the retaining meshing part of the tourniquet, it is impossible to remove it, ensuring stable ligation and ensuring the bleeding of blood vessels, and slipping with fat like hemostasis with conventional forceps. This eliminates any risk of bleeding due to unreliable hemostasis, such as dropping or ligating using a suture needle and a suture, enabling quick and reliable ligation and tightening. Ligated band The anti-slip ribs cut into the ecological tissue to prevent inadvertent misalignment, not only greatly reducing the burden on surgeons, but also significantly shortening the time required for surgery and safer surgical treatment. This makes it possible to obtain an excellent feature. In addition, only one kind of ligation band having a width of about 1.5 to 2.5 mm, a thickness of about 1 mm, and a length of about 70 to 80 mm of the tourniquet is prepared, and dogs, cats, and the like are prepared. The ability to accommodate a wide range of physiques, from kittens to large dogs, in mammals, will produce significant results with minimal expense.
[0034]
Further, according to the hemostasis method using the ligation band of the present invention, if it is conventional, use forceps according to the bleeding site, perform ligation, or perform external compression in the case of trauma. There were many situations that required various actions, such as, but when using the ligation band, it could be used for hemostasis of blood vessels and organs in the body cavity, as well as laceration reaching arteries and veins A relatively large ligating band can be wrapped around the limb and used for temporary hemostasis during suturing of the torn site or blood vessel.
[0035]
Furthermore, according to the method for removing an organ using the ligation band of the present invention, and the method for removing ovaries from the uterus of a mammal, if it is a conventional method, an over-fertilized dog, a proper ovary cord, an ovary in a cat, or the like, The ovaries are in the form of a fat mass, the hand slips due to fat, and even sending the suture to the deep part is a difficult task, and the time required for surgery such as ovarian hysterectomy increases the time required for doctors However, by using the ligating band, there is no need to send the suture needle deep into the abdominal cavity, and there is no risk of damaging surrounding organs. It was necessary to take measures such as ligating several times or piercing sutures as necessary, depending on the condition of the organ and its surroundings. Ligation van By wrapping and tightening in a loop, ligation and hemostasis can be performed reliably with a single procedure, shortening the operation time, reducing the burden on the mammal undergoing the operation, and performing a safer operation Once the ligating band has been securely attached, it does not come off accidentally during surgery, so the surgeon can concentrate on the procedure without worry. Will do.
[0036]
In particular, the ligation band 1 described in the embodiment has, in addition to the above-described features, a fastening hole 24 through which a suture needle and a suture can pass through at a proper position on the base end side of the tourniquet body 2. With such a configuration, even in a case where there is a possibility of falling off due to the shape or fat of the fastening part of the living body, the suture needle and the suture are inserted into the fastening holes 24 of the ligating band that is fastened in a ring shape. It can be securely fixed to the tightening site by passing through and suturing, etc., so that the attached ligating band can be more securely prevented from falling off, and also in the width direction of the tourniquet body. By forming a recessed fastening groove at the edge to enable the suture to be locked, it is possible to more reliably prevent the ligating band from falling off.
