Chemotherapy puncture positioning device capable of adjusting positioning distance

Abstract

The invention discloses a chemotherapy puncture positioning device capable of adjusting a positioning distance, solves the problems of unstable positioning and non-adjustable positioning distance of apuncture needle in the prior art, and has the effects that the positioning distance can be adjusted according to different puncture depths, the positioning is stable, and a contact area between a puncture position and an external environment is reduced. According to the technical scheme, the device comprises a transverse adjusting mechanism capable of clamping or loosening the puncture needle, the transverse adjusting mechanism is connected with a fixing mechanism through a plurality of longitudinal telescopic mechanisms which are evenly arranged at intervals, and the fixing mechanism is connected with a protection device; the transverse adjusting mechanism is adjusted to enable the longitudinal telescopic mechanism to extend or retract to change the positioning distance; wherein the transverse adjusting mechanism comprises a first positioning ring and a driving ring which are arranged together in a sleeved mode, the driving ring can rotate relative to the first positioning ring, anda transverse telescopic mechanism is arranged on the inner side of the first positioning ring.

Description

technical field [0001] The invention relates to the technical field of chemotherapy puncture, in particular to a chemotherapy puncture positioning device capable of adjusting the positioning distance. Background technique [0002] Chemotherapy puncture is a treatment method for diseases in the medical field. It requires the use of puncture needles and infusion ports and other related equipment. The infusion port is a closed infusion device implanted in the human body, and the puncture needle is used to treat the lesions. For puncture aids, during the chemotherapy puncture process, a puncture positioning device is usually used to position and clamp the puncture needle. The inventor found that the following problems exist in the positioning of the puncture needle at present: [0003] (1) The existing puncture needle usually needs manual support from medical staff after the puncture is completed, which improves the labor intensity of the medical staff. At the same time, the pu...

AI Technical Summary

Problems solved by technology

[0003] (1) The existing puncture needle usually needs manual support by medical staff after the puncture is completed, which increases the labor intensity of the medical staff. At the same time, the puncture needle is prone to displacement and deviation, and the traditional positioning device cannot adjust the position according to the length and diameter of the puncture needle. Make adjustments, resulting in unstable positioning of the puncture needle;

[0004] (2) The traditional positioning device cannot adjust the positioning distance according to the length of the puncture needle itself, so that the puncture depth of the puncture needle in the human body cannot be adjusted, which is not conducive to accurate treatment of lesions, thus affecting the normal treatment effect
