Description

Novel atraumatic vascular blocking forceps Technical Field The utility model relates to the technical field of vascular clamps, in particular to a novel atraumatic vascular blocking clamp. Background The vascular blocking forceps are a special instrument commonly used in vascular surgery, are mainly used for temporarily clamping blood vessels in the process of surgery to control bleeding or provide an operation space, are generally made of high-quality stainless steel materials, have the characteristics of corrosion resistance and fatigue resistance, ensure the safety of long-term use, and are in different structures such as straight structures, bent structures and the like, so as to adapt to different surgical demands. However, when the traditional vascular occlusion forceps are operated, the closed state of the occlusion end switch is controlled by continuously squeezing and applying force by the index finger and thumb of the hand, and the hand is easy to fatigue and acid bulge due to long-time operation, so that the smooth operation is affected, and a doctor often faces higher operation difficulty under an emergency. Disclosure of utility model The present utility model aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present utility model is to provide a novel atraumatic vessel occlusion clip which can be opened and closed by pressing and releasing a push rod to thereby simplify the operation steps, improve the efficiency, and ensure stable and reliable vessel occlusion. In order to achieve the above purpose, the novel harmless vascular occlusion clamp comprises a cylinder body, wherein two handles are symmetrically arranged on the outer wall of the cylinder body, a push rod penetrates through the top of the cylinder body, a fixing rod is fixedly connected to the inner wall of the cylinder body, two clamping plates are symmetrically and slidably arranged on the fixing rod, balls are arranged on adjacent sides of the two clamping plates, springs are fixedly connected to opposite sides of the two clamping plates, the springs are sleeved outside the fixing rod, a conical rod is fixedly connected to one end of the bottom of the push rod, and the outer wall of the conical rod is attached to the balls to slide. Preferably, concave-convex clamping teeth are arranged on one side adjacent to the two clamping plates and close to one end of the bottom. Preferably, an arc-shaped groove is formed in the bottom of the handle. Preferably, one end of the top of the push rod is fixedly connected with a pressing plate. Preferably, the repelling sides of the two clamping plates are fixedly connected with limiting rings, and one end of the spring is positioned in the limiting rings. Preferably, the top of the pressing plate is provided with anti-skid patterns. Compared with the prior art, the vascular occlusion clamp has the beneficial effects that the tapered rod fixedly connected with the bottom moves downwards by manually pressing the push rod, the clamping plate is pushed to open, the balls on the outer wall of the tapered rod and the adjacent side of the clamping plate slide, an occlusion space is provided, after the push rod is loosened, the spring returns the clamping plate to the original position, the push rod is reset, the vascular occlusion fixation is realized, the operation steps can be simplified through single pressing and loosening operation, the efficiency is improved, and the vascular occlusion is ensured to be stable and reliable.
