Problems solved by technology

[0002] At present, there are many kinds of puncture guns, but there is no report that the puncture gun can adjust the puncture depth. The existing puncture guns rely on doctors to judge the puncture depth through experience. Repeated punctures due to poor depth lead to unnecessary suffering for the patient

Abstract

The invention discloses a puncture gun with adjustable puncture depth. The puncture firing distances of a puncture needle and a puncture cylinder of the puncture gun can be synchronously adjusted by setting a gear shifting member. The specific structure of the gear shifting member includes a rotating shaft and two gear shifting blocks spaced forward and backward on the rotating shaft, and the lower parts of the rear ends of the gear shifting blocks respectively extend backward by the same length. When the rotating shaft is rotated until the extending portion of each gear shifting block is located below, the firing distances of two sliding blocks are the longest. When the rotating shaft is rotated until the extending portion of each gear shifting block is located above the rotating shaft, the firing distances of the two sliding blocks are the shortest, and the difference between the longest distance and the shortest distance is the length of the extending portion of each gear shifting block. The puncture gun is simple in structure, high in safety, and easy to use.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to a puncture gun with adjustable puncture depth. Background technique [0002] At present, there are many kinds of puncture guns, but there is no report that the puncture gun can adjust the puncture depth. The existing puncture guns rely on doctors to judge the puncture depth through experience. Repeated punctures due to poor depth lead to unnecessary suffering for the patient. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a piercing gun with adjustable piercing depth, which is easy to use and safe. [0004] In order to achieve the above object, the technical solution of the present invention is as follows: a puncture gun with adjustable puncture depth, comprising a puncture needle and a puncture barrel, one end of the puncture needle and the puncture barrel is respectively provided with a c...
