High-frequency punching machine for tube body

Abstract

The invention relates to a high-frequency punching machine for a tube body. The punching machine is characterized by comprising a mounting bottom plate, an electrode rod, a punching head assembly and an electric cabinet; an electrode supporting frame is fixed on one side of the mounting bottom plate, an insulating bracket is fixed on the other side of the mounting bottom plate; one end of the electrode rod is arranged on the electrode supporting frame, while the other end is arranged in a mounting groove of the insulating bracket; the mounting bottom plate is provided with a punching head sliding plate bracket, a punching head sliding plate is arranged on the punching head sliding plate bracket, an insulating plate and the punching head assembly are fixed on the punching head sliding plate, and the punching head sliding plate is connected with a sliding plate pedal controller; the electric cabinet is communicated with the mounting bottom plate and the punching head assembly respectively; and a high-frequency pedal switch connected with the electric cabinet is arranged below the mounting bottom plate. The high-frequency punching machine has the advantages that: the tube body is heated at the same time of punching by using the high-frequency thermal bonding principle so that the punched orifice is smooth and a sharp orifice formed on the outer wall of the tube body is avoided; and when a cannula is inserted into the body of a patient, other visceral organs of the patient are not injured, and the use safety performance of the intravenous cannula is further improved.

Description

technical field [0001] The invention belongs to the technical field of pipe body processing, in particular to a high-frequency punching machine for pipe bodies. Background technique [0002] At present, in the surgical operation process, the extracorporeal blood circulation technology has been widely used in clinical practice by taking human blood (vein) out of the body for gas exchange into arterial blood and then reinfusing it into the body to assist the success of the operation and achieve the purpose of treatment. Such as organ transplantation, respiratory surgery, neurosurgery, emergency rescue and other operations, especially in cardiovascular surgery, about 50% of them are completed with the assistance of extracorporeal circulation. The venous cannula is a special drainage cannula inserted into the veins of the human body when cardiac surgery establishes extracorporeal circulation. The venous cannula is a straight-through tube body with a porous interface at the front...

AI Technical Summary

Problems solved by technology

In the known technology, the long round hole on the venous cannula is directly punched out on the tube wall through the cylinder-driven punching machine. Since the hole punched out by the above-mentioned punching machine will form a right-angled edge on the outer wall of the tube, that is, a very sharp edge is formed. When the medical staff inserts the venous catheter into the patient's body, it will damage other organs of the patient, which not only brings a lot of trouble to the medical staff's operation, but also causes unnecessary pain to the patient
