Novel puncture trocar and using method thereof

Abstract

The invention belongs to the technical field of puncture needles, and specifically relates to a novel puncture trocar and a using method thereof. The novel puncture trocar structurally comprises a sleeve, wherein the sleeve is internally connected with a hollow puncture needle of which the front end protrudes out of the sleeve in a sleeving way; the tail end of the sleeve is fixedly connected witha supporting seat; the supporting seat is connected with a movable block in a sliding and sleeving way; a transfusion channel is formed in the movable block; the tail end of the hollow puncture needle is fixedly connected with the movable block; the hollow puncture needle is correspondingly communicated with the transfusion channel; a fluid communicating pipe is arranged at one opposite side, which is connected with the hollow puncture needle, of the movable block; the fluid communicating pipe is correspondingly communicated with the transfusion channel; an actuating mechanism is also arranged above the movable block. The novel puncture trocar provided by the invention is simple in structure and is capable of completing operation by one hand; the using method of the novel puncture trocaris correspondingly provided. The operability of the puncture trocar in clinical medical treatment and biomedical experiments is remarkably increased, and practical significance is obtained.

Description

technical field [0001] The invention relates to the technical field of puncture needles, in particular to a novel puncture trocar. Background technique [0002] In the process of clinical treatment and biomedical experiments, it is often necessary to use puncture needles for infusion or tissue perfusion. Three types of needles are commonly used in blood vessel access, as follows: [0003] The easiest way is to use traditional scalp acupuncture. The operator punctures the blood vessel with a sharp needle and advances the sharp needle into the blood vessel. Once the needle is confirmed to be in the blood vessel, the operator secures the needle and starts the infusion so that the needle stays in the blood vessel. However, if the spatial position of the blood vessel moves or the scalp needle moves, the needle tip may accidentally puncture the blood vessel, resulting in failure of the experiment or injury to the patient, requiring re-puncture and increasing the workload.
