Description
Technical Field
The utility model belongs to the technical field of medical operation puncture guide needle, concretely relates to medical operation puncture guide needle.
Background
In surgical operation, a drainage tube is required to be placed in an operation incision, and hematocele and effusion in an operation cavity are led out of the body through the drainage tube. Thus, the effusion infection of the operation cavity can be prevented, and the wound healing is promoted. At present, the method adopted in the operation is to take a section of silicone tube, place one end (drainage section) of the tube into a cavity, and lead out the other end of the tube from a small skin hole which is cut in addition, and connect a negative pressure drainage ball. So as to achieve the purpose of drainage. The disadvantage of this is that the skin incision is manually made, the size is not easy to control, if it is too large, the sealing performance will be affected, and no negative pressure will be formed. If too small, the drainage tube will not easily pass out, or if it is too tight, it will affect the blood flow at the incision. While opening the hole increases the new wound for the patient. In addition, suture-securing drains may be too loose or too tight. If the drainage tube is too loose, the drainage tube is not easy to fix and is easy to fall off; too tight can affect clot drainage within the tube. At present, a puncture guide needle is gradually used by a hospital to complete the operation of placing a drainage tube, the type of guide needle is formed by grinding 304 stainless steel needle blanks, the grinding direction of a groove of a needle point blade part is formed by transverse grinding, when the guide needle blade part penetrates through the organism tissue of a patient during operation, the grinding grain of the blade part is inconsistent with the texture of the skin tissue of the human body, and when the needle point blade part penetrates through the organism tissue of the human body, the inverse grain of the needle point blade part can cause wound to the patient.
