Tumor interventional therapy device

Abstract

The invention discloses a tumor interventional therapy device, which comprises a guiding catheter, a puncture tube, a needle, an outer sleeve and a push rod, wherein the tail end of the guiding catheter is in threaded connection to the front end of the outer sleeve by virtue of a hard threaded connecting pipe; the guiding catheter is a rubber pipe, and the guiding end of the guiding catheter is of a spherical structure; a plurality of blood suction tubes are arranged in the guiding catheter; each blood suction tube runs through the outer wall of the guiding catheter and is connected to a corresponding gourd-shaped airbag; the puncture tube and the needle are integrally molded, and the puncture tube is connected to the push rod by virtue of a screw thread; the push rod is connected to an armrest by virtue of a connecting rod; a disinfecting cavity is formed in the outer sleeve; a port, which is used for changing disinfecting cotton, is formed in one side of the disinfecting cavity; sliding rails are symmetrically arranged on the inner walls of the upper and lower sides of the outer sleeve; two sides of the push rod are movably connected to the sliding rails by virtue of sliding blocks which are provided with servo devices; and a pressure sensor is additionally arranged in the outer sleeve. When the therapy device disclosed by the invention is used, surrounding tissues can be clearly observed and a puncture depth can be accurately controlled; and the therapy device is convenient to use, high in puncture success rate and high in automation degree.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tumor interventional therapy device. Background technique [0002] At present, it is generally necessary to use tumor interventional puncture needles for tumor treatment. The tumor interventional puncture needles used in hospitals are the same as ordinary puncture needles. The structure of ordinary puncture needles is composed of a needle body and a needle handle. When ordinary puncture needles are used for tumor interventional therapy for patients, due to the short handle of ordinary puncture needles, cross-infection is prone to occur, which brings difficulties to the staff; in addition, the puncture needles used now require manual operation of the needle Needle handle, the staff should not only pay attention to cross-infection, but also need to contact the shorter needle handle, which increases the burden on the staff, is inconvenient and inconvenient, and the work ef...

[0002] At present, it is generally necessary to use tumor interventional puncture needles for tumor treatment. The tumor interventional puncture needles used in hospitals are the same as ordinary puncture needles. The structure of ordinary puncture needles is composed of a needle body and a needle handle. When ordinary puncture needles are used for tumor interventional therapy for patients, due to the short handle of ordinary puncture needles, cross-infection is prone to occur, which brings difficulties to the staff; in addition, the puncture needles used now require manual operation of the needle Needle handle, the staff need to pay attention to cross-infection, but also need to contact the shorter needle handle, which increases the burden on the staff, is troublesome and inconvenient, and the work efficiency is low

At the same time, when the puncture is performed, the boundary of the surrounding tissue is not clear, which affects the doctor's diagnosis and adds great difficulty to the medical staff.
