Abstract

The invention discloses a prostate seed implantation gun and a use method thereof. It relates to the field of medical technology, the sleeve is provided with a slot hole and a sliding groove, a telescopic rod is embed in the slot hole, the inner needle and the loc mechanism thereof and the pull ring are integrated through screw connection, and the end position of the telescopic rod is provided with a pull rod. By adjusting the relative position of the pull rod in the sleeve, the relative position of the inner needle and the locking mechanism thereof in the sleeve can be changed, and the working space of the inner needle and the locking mechanism thereof can be shortened. The telescopic rod is provided with a sliding groove, and the insertion depth of the inner needle can be changed by adjusting the relative position of the pull ring on the sleeve, so as to meet the needle insertion requirements of different patients. The inner needle and the outer needle are provided with a clamping mechanism, and the clamping head and the clamping head cap are provided with threads. The clamping force of the inner needle and the outer needle can be changed by adjusting the screw length of the threads, so that the inner needle and the outer needle can be clamped or loosened, so that the inner needle and the outer needle can be changed and cleaned before the operation.

Description

technical field [0001] The invention belongs to the field of medical technology, in particular to a prostatic particle implant gun and its usage method. Background technique [0002] The patent with the authorized notification number CN201551730U discloses a casing gun type radioactive particle implantation device, which includes a gun body, inserting nipples on the front and rear sides of the gun body, and a catheter for installing a push rod , and installed with a bushing to connect the tail cap. The device designed in this way can prevent the longer push rod from being damaged outside, so that the push rod moves in the casing and the gun body, and the casing slides on the casing support. However, the push rod has a large working space, which may cause instability during operation, and the long-term use of the catheter will cause the catheter to deform and may reduce the positioning accuracy, thereby affecting the treatment effect of the patient. [0003] At present, it ...
