Abstract
The utility model discloses a novel liver cyst puncture needle. The puncture needle is connected with a negative pressure device through a soft catheter. A control valve is arranged on the soft catheter. The puncture needle is provided with measurement scales and a positioning sliding block. A needle head of the puncture needle is of a sealing cone shape. A pipe wall of the inserting end of the puncture needle is provided with a protruding cross beam which is symmetrical in up and down, left and right. The pipe wall of the inserting end of the puncture needle and the protruding cross beam are respectively provided with a plurality of needle holes. Each needle hole is of a horn shape, and the outer side caliber of each needle hole is larger than the inner side caliber. The novel liver cyst puncture needle is reasonable in structure, and convenient to use, through arrangement of the protruding cross beam and the thorn-shaped needle holes, the needle holes are not easy to block due to the fact that the pipe wall of the puncture needle is not easy to totally surround from outside by a cystic wall, and therefore smooth extraction of cystic fluid is guaranteed, and work difficulty of medical staff and suffering of patients are reduced.
Description
Technical field
This utility model relates to technical field of medical instruments, especially a kind of novel liver cyst puncture needle.
Background technology
Along with science and technology development, the dehydrated alcohol hardening process that a kind of safety, economy, the little Minimally Invasive Surgery of patient suffering are treated hepatic cyst is widely used, and it is made up of puncture needle and syringe; Weak point is that puncture needle needle point in piercing process is when puncturing the wall of cyst; The pin hole of puncture needle is prone to blocked, in addition, and along with the extraction of capsule liquid; Blister cavities constantly dwindles, and the phenomenon that cyst wall stops up the puncture needle pin hole at this moment also can occur.
The utility model content
The purpose of this utility model is in order to overcome above-mentioned technical disadvantages a kind of novel liver cyst puncture needle to be provided.
The technical scheme that this utility model technical solution problem adopts is: a kind of novel liver cyst puncture needle; Puncture needle is connected with negtive-pressure implement through flexible catheter; Flexible catheter is provided with control valve, and puncture needle is provided with metering scale and positioning sliding block, and the syringe needle of puncture needle is the closed circular taper; About the insertion end tube wall of said puncture needle is provided with, about symmetrical protruding crossbeam; The tube wall of insertion end and protruding crossbeam are provided with a plurality of pin holes, and said pin hole is horn-like, and outside bore is greater than inboard bore.
The beneficial effect that this utility model had is:
This utility model reasonable in design; Easy to use, owing to be provided with protruding crossbeam and trumpet-shaped pin hole, cyst wall is not easy to hold the puncture needle tube wall fully from the outside and causes pin hole to stop up; Guarantee the smooth extraction of capsule liquid, alleviated medical worker's work difficulty and patient's misery.
Description of drawings
