Vascular clamp, closed tongs, vascular clamp die and production method of vascular clamp

Abstract

The invention relates to a vascular clamp, an occlusion clamp, a vascular clamp mould, and a method for manufacturing the vascular clamp. The vascular clamp has a V shape and is provided with clamp rods, a clamp hook, a clamp seat and clamp rod seats, wherein two clamp rods on two sides are bent and connected; the head part of one clamp rod is provided with the clamp hook and one clamp rod seat; the head part of the other clamp rod is provided with the other clamp rod seat and the clamp seat matched with the clamp hook; and the vascular clamp is made of elastic materials. The occlusion clamp is provided with an occlusion clamp sleeve hook matched with the clamp rod seats. The vascular clamp mould is provided with a vascular clamp mould groove, a mould gate and a flow passage which are communicated. The method for manufacturing the vascular clamp comprises the following steps: making early-stage preparation; performing heating reaction on plants, namely corns through catalysis under normal pressure, extracting a solution, and polymerizing the solution to generate synthesis plastic resin; performing air baking treatment on the synthesis plastic resin; and injecting the synthesis plastic resin into the vascular mould to form the vascular clamp. The vascular clamp has the advantages of reasonable structural design, good clamping and closing effects, convenient and safe surgical use and high reliability.

Description

Technical field: [0001] The invention relates to a blood vessel clip, closing forceps, a blood vessel clip mold and a manufacturing method of the blood vessel clip, which are mainly used for permanent closure of blood vessels in the human body during minimally invasive surgical operations. Background technique: [0002] In the process of human minimally invasive laparoscopic surgery, once a lesion is found in the human body, it needs to be resected. During the resection operation, the blood vessels and capillary organs in the body need to be permanently cut off and clamped. Suture clipping, the disadvantage is that the operation time is long, the operation is difficult, and the surgeon must have a high-tech suture knotting level. If the thread is not tightly ligated, it will cause loose thread or thread off, causing internal bleeding in the patient, and the wound will heal The second is that there are other closed clips, such as commonly used titanium clips, and its defects ...

Problems solved by technology

[0002] In the process of human minimally invasive laparoscopic surgery, once a lesion is found in the human body, it needs to be resected. During the resection operation, the blood vessels and capillary organs in the body need to be permanently cut off and clipped. Suture clipping, the disadvantage is that the operation time is long, the operation is difficult, and the surgeon must have a high-tech suture knotting level. If the thread is not tightly ligated, it will cause loose thread or thread off, causing internal bleeding in the patient, and the wound will heal The second is that there are other closed clips, such as commonly used titanium clips, and its defects are: first, the titanium clip is a metal material, and the patient has nuclear magnetic effects in CT and B-ultrasound examinations; It may dissociate to other parts of the human body and cause other pathogens in the human body; the fourth is the metal titanium clip. The patient needs to undergo a second operation to remove the metal titanium clip after the wound has healed

Therefore, the ideal surgical effect cannot be satisfied
