Description

Technical Field

[0001] The present application relates to the technical field of agricultural and animal husbandry product processing tools, and in particular to an animal bladeless ligation knife and a ligation device. Background Art

[0002] Cow bile is rich in bile salts and bilirubin, which can be used for the separation and purification of biochemical products. However, during the collection and transportation of the gallbladder, bile leakage and contamination may occur due to failure to tightly ligate the neck of the gallbladder. Bile is sterile in living organisms, and sterile bile can be harvested under aseptic operation for the purification of functional products. However, if bile leaks during gallbladder transportation, it will not only cause bile loss, but also microbial contamination of the bile, and even produce microbial toxins due to contamination, which may ultimately seriously affect the quality of products prepared using bile.

[0003] The traditional method of ligating the gallbladder of cattle is to tie the neck of the gallbladder with a rope, and when tightening it, the peritoneal ligament at the connection between the gallbladder and the liver is often tied together due to manual threading of the rope. This method of ligating muscles and ligaments together makes it difficult to tighten the elastic muscles and ligaments, which can easily cause the rope to loosen and lead to bile leakage.

[0004] Therefore, there is currently no effective cattle gallbladder ligation device that can solve the problem of bile leakage after gallbladder ligation. Utility Model Content

[0005] The embodiment of the present application provides a bladeless ligation knife and a ligation device, which are used to solve the problem of bile leakage after gallbladder ligation in the prior art.

[0006] The embodiment of the present application provides a bladeless ligation knife, comprising:

[0007] A blade head, a blade body and a handle, wherein the blade head and the blade body are an integrated structure, and the handle is fixedly mounted on the rear end of the blade body;

[0008] The cutter head is a conical structure;

[0009] The blade body is a hollow structure; the blade body includes a notch, and the notch is located on the top surface of the blade body; the blade body also includes a tightening hole, and the tightening hole is located on the bottom surface of the blade body; the bottom surface of the blade body is arc-shaped.

[0010] Furthermore, the notch and the bottom surface of the blade body are connected with a rounded transition.

[0011] An embodiment of the present application also provides a ligation device, comprising the above-mentioned bladeless ligation knife and a tightening unit, wherein the tightening unit is used to tighten the gallbladder neck.

[0012] Further, the tightening unit comprises a first tightening component and a second tightening component having the same structure;

[0013] The first tightening component is pre-placed in the notch of the blade before the gallbladder is ligated;

[0014] The tightening unit is used to, after the first tightening component and the bladeless ligation knife synchronously penetrate the muscle tissue near the gallbladder, withdraw the bladeless ligation knife so that the first tightening component remains in the muscle tissue; connect the end of the first tightening component with the top of the second tightening component, and connect the top of the first tightening component with the end of the second tightening component after bypassing the part to be ligated of the gallbladder; the first tightening component and the second tightening component are used to make the two tightening components generate tension on each other when external tension acts on the top of the two components synchronously, so as to reduce the spatial distance between the two components.

[0015] Furthermore, the first tightening component and the second tightening component are used to make the two components generate a pulling force on each other when an external pulling force acts on the top ends of the two components synchronously, so as to reduce the spatial distance between the two components, including:

[0016] The top ends of the two tightening components are respectively inserted into the tightening holes of the bladeless ligation knife, and the bladeless ligation knife is rotated to pull the two tightening components, so that the two tightening components generate a pulling force on each other to reduce the space distance between the two components.

[0017] The beneficial effects of this application include:

[0018] Compared with the conventional method of ligating the gallbladder with a rope, the bladeless ligation knife and ligation device provided in the embodiment of the present application can accurately penetrate the muscle tissue at the connection between the gallbladder and the liver through the ligation knife, so that the first tightening component can accurately pass through the position to be ligated. Further, after tightening the first tightening component and the second tightening component, the spatial distance between the two tightening components can be effectively shortened, and finally the effective ligation of the gallbladder neck can be achieved, which can solve the problem of easy leakage of bile in the gallbladder after gallbladder ligation in the prior art.

It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other if there is no conflict.

[0027] The present application embodiment provides a bladeless ligation knife, such as Figure 1-4 As shown, including:

[0028] A blade head 1, a blade body 2 and a handle 3, wherein the blade head 1 and the blade body 2 are an integrated structure, and the handle 3 is fixedly mounted on the rear end of the blade body 2;

[0029] The cutter head 1 is a conical structure;

[0030] The blade body 2 is a hollow structure; the blade body includes a notch 21, which is located on the top surface of the blade body 2; the blade body 2 also includes a tightening hole 22, which is located on the bottom surface of the blade body 2; the bottom surface of the blade body is arc-shaped.

[0031] Compared with the conventional method of ligating the gallbladder with a rope, the bladeless ligation knife provided by the present application can accurately penetrate the muscle tissue at the connection between the gallbladder and the liver, and then the first tightening component can accurately pass through the position to be ligated, which can avoid the problem of the gallbladder neck not being able to be sealed due to the peritoneal ligation at the connection between the gallbladder and the liver in the existing ligation method. Therefore, further, the bladeless ligation knife provided by the present application can achieve effective ligation of the gallbladder neck during the gallbladder ligation process, which can solve the problem of easy leakage of bile in the gallbladder after gallbladder ligation in the prior art.

[0032] The above-mentioned bladeless ligation knife includes a handle 3 structure. When the bladeless ligation knife is used to puncture muscle tissue, by holding the handle 3 and pushing the bladeless ligation knife to move, the puncture force can be released and effective puncture can be achieved. The material of the handle 3 can be any non-slip material such as rubber, silicone, etc. The handle 3 may include an anti-slip ring. In order to better fix the handle 3 on the blade body 2, a fixing pin may be added between the blade body 2 and the handle 3.

[0033] In the embodiment of the present application, the blade head 1 of the above-mentioned bladeless ligation knife is designed to be a conical structure, the blade body 2 is designed to be a hollow structure, and the blade body 2 includes a special design of a notch 21 located on the top surface of the blade body, so that the entire bladeless ligation knife does not contain a blade, that is, during the puncture operation of gallbladder ligation, cutting of the muscle tissue of the living body can be avoided as much as possible to reduce damage to the living organism.

[0034] In addition, in order to effectively reduce the damage to living organisms, the bladeless ligation knife provided in the embodiment of the present application also includes the following special structural design: the end of the blade body 2 close to the blade head 1 is a bevel, such as Figure 2 As shown, the angle between the inclined surface and the bottom surface of the blade body 2 is an obtuse angle, and the transition is in a circular arc; the notch 21 and the bottom surface of the blade body 2 are connected by a rounded transition.

[0035] The material of the blade head 1 and the blade body 2 of the bladeless ligation knife provided in the embodiment of the present application can be any material with a certain hardness, such as metal, plastic, or PP.

[0036] Another embodiment of the present application provides a ligation device, such as Figure 1-5 As shown, it comprises: a bladeless ligation knife and a tightening unit, the tightening unit is used to tighten the gallbladder neck. The tightening unit comprises a first tightening component 4 and a second tightening component with the same structure.

[0037] In actual use, the first tightening component 4 can be placed in the notch 21 of the blade body 2 before the gallbladder ligation and puncture, the top of the first tightening component 4 is placed near the blade head 1, and the end of the first tightening component 4 is placed near the handle 3. During the puncture operation of gallbladder ligation, the first tightening component 4 can move synchronously with the bladeless ligation knife and penetrate the muscle tissue near the gallbladder. After the first tightening component 4 and the bladeless ligation knife synchronously penetrate the muscle tissue near the gallbladder, the bladeless ligation knife is pulled out, leaving the first tightening component in the muscle tissue; thereafter, the end of the first tightening component 4 can be connected to the top of the second tightening component, and the top of the first tightening component 4 is connected to the end of the second tightening component after bypassing the gallbladder neck to be ligated at the gallbladder. After the two tightening components are connected, a sealed ring surrounding the gallbladder neck will be formed between the two tightening components. By applying external tension and acting on the top ends of the two tightening components simultaneously, the two tightening components can generate tension against each other. As the tension increases, the spatial distance between the two tightening components can be reduced, and the gallbladder neck between the two tightening components can be tightened accordingly, ultimately achieving the effect of sealing the gallbladder neck to prevent bile leakage.

[0038] In actual use, after the top ends of the two tightening components are connected respectively, the top ends of the two tightening components are respectively inserted into the tightening holes 22 of a bladeless ligation knife, and the bladeless ligation knife is rotated to pull the two tightening components, so that the two tightening components generate a pulling force on each other to reduce the space distance between the two components.

[0039] In order to achieve the effect of sealing the gallbladder neck, the tightening unit can be a cable tie or other materials having the same function or effect as the cable tie.
