Abstract
The invention relates to medical equipment, and in particular relates to a trocar for subcutaneous puncture and assist completion of medicament embodiment. The trocar comprises a core bar, a trocar base and a trocar tube, wherein the trocar base is internally provided with a through hole; the trocar tube is fixedly connected with the trocar base; and the through hole is communicated with the trocar tube; key slots are formed on the inner wall of the through hole of the trocar base; a core bar key and a plurality of keys matched with the key slots are arranged on the core bar; and the core bar key is arranged at the tail end of the core bar. The trocar has the beneficial effects that 1, the medicament is positioned and guided in a classifying way; 2, the keys can be protected to avoid misoperation, and the trocar can be self-locked and out of operation, so that the trocar can be protected; and 3, the trocar can be automatically self-locked to complete self-destruction after being used due to the arrangement of a pothook and a trocar base lock hole, so that the secondary use can be avoided, and the cross infection can be avoided.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, relate in particular to a kind of subcutaneous puncture that is used for, the auxiliary embedding trocar of medicament of accomplishing.
Background technology
At present, clinically, subcutaneous puncture is used widely; And the mode of embedding medicament is also implemented to come behind the subcutaneous puncture, adopts the trocar, can make its needle point puncture to subcutaneous precalculated position; Insert medicament, extract needle point out, so the trocar can satisfy clinical requirement.
Existing trocar positioning and guiding property generally speaking is bad, and trocar repeated use, causes cross infection easily.
Summary of the invention
For solving the problems of the technologies described above, the present invention propose a kind of can classification positioning and guiding medicament, and the trocar of locking voluntarily after using.
Technical scheme of the present invention is: a kind of trocar comprises core bar 1, needle stand 2 and needle tubing 3; Be provided with through hole 23 in the said needle stand 2, needle tubing 3 is fixedly connected with needle stand 2, and through hole 23 is communicated with needle tubing 3.
Said needle stand 2 through holes 23 inwalls are provided with keyway 22, and said core bar 1 is provided with the key that core bar key 11 and a plurality of and said keyway 22 are complementary, and core bar key 11 is positioned at core bar 1 end.
The quantity of said key is 1～3.The quantity of key requires to confirm according to clinical practical operation.
Said core bar 1 top is provided with the protected key 14 that is complementary with keyway 22.
Said core bar 1 top is provided with hook 15, and said needle stand 2 is provided with the lockhole 21 that is complementary with said hook 15.
Said needle tubing 3 outsides are provided with protective sleeve 4, and said protective sleeve 4 is socketed on needle stand 2 ends.
Said keyway 22 cooperates with core bar key 11, key and protected key 14 on the core bar 1, reaches the purpose to core bar 1 stop/release; Lockhole 21 on the needle stand 2 cooperates with the hook 15 of core bar 1, reaches the purpose of core bar 1 and needle stand 2 lockings.
Beneficial effect of the present invention is: 1, classification positioning and guiding medicament; 2, protected key 14 can be avoided maloperation, causes the product self-locking to be lost efficacy, and plays a protective role; 3, hook 15 can lock the completion self-destruction with the trocar that is arranged so that of needle stand 2 lockholes 21 voluntarily after finishing using, and avoids secondary to use, and prevents cross infection.
