Description
Technical field
This utility model relates to medical device, and a kind of specifically ridge shape hollow liver is threaded a needle, and is applied in the medical hepatic tissue biopsy puncture.
Background technology
At present, the liver of the clinical use kind of threading a needle is more, only has the function of obtaining BIAO and BEN, function singleness mostly; Do not possess the function that detects and dispose the complication that possibly occur in the piercing process, poor stability can not carry out injection for curing to diseased region; The scope of application is little, and some pin type is simple in structure, and tissue injury's scope is bigger; Complication is many, and the patient is easy to generate the feared state of mind, brings difficulty to clinical position.
Summary of the invention
This utility model technical problem to be solved is the deficiency that overcomes prior art; Provide a kind of ridge shape hollow liver to thread a needle, this utility model solves the technical scheme that its technical problem adopted and is: the structure of this utility model comprises needle guard, nook closing member, BIAO and BEN groove, joint, scale, it is characterized in that being provided with in the needle guard nook closing member; Nook closing member is a hollow structure; Needle guard is provided with the BIAO and BEN groove, and needle guard one end is connected with joint, and the needle guard surface also is provided with scale.
Operation principle and method for using: this utility model has increased ridge shape hollow needle cored structure on the ejection type liver is threaded a needle the basis, make puncture procedure more steady, and needle point is sharper; Broken skin and inserting needle are more prone to during puncture; The needle guard afterbody is furnished with syringe adapter, and whether blood and the bile that can be used for aspirating the site of puncture mistake takes place is worn complication such as blood vessel and bile duct to detect, and can inject hemostasis and suppository is remedied disposal; In addition; Also can carry out treatments such as anhydrous alcohol injection, medical personnel can be placed on the BIAO and BEN that extracts in the BIAO and BEN groove on the needle guard, have increased the safety and the scope of application greatly; Bring very big facility to clinical position, alleviated the tissue injury and the feared state of mind the patient.
The beneficial effect of this utility model is, this utility model is rational in infrastructure, and is easy to use, both can collect specimen, have suction and function of injection again, and increased the safety and the scope of application of liver puncture greatly, alleviated the tissue injury and the feared state of mind to the patient.
