Auxiliary device for treating large pelvic cyst and abdominal cyst in combination with injection under ultrasonic guidance

Abstract

The invention discloses an auxiliary device for treating larger pelvic and abdominal cyst in combination with injection under ultrasonic guidance, and relates to the field of medical instruments, the auxiliary device comprises an extension part, one end of the extension part is connected with an abutting block, the outer side of the extension part is provided with a rotating knob, and one side of the rotating knob is connected with a threaded rod. After the liquid extraction position is predicted through ultrasonic equipment, the puncture length of the puncture needle is calculated on the puncture needle, and after adjustment and determination, a rotary knob is screwed to drive a threaded rod to rotate, so that an extrusion block and an extrusion pad are driven by a moving block to move on one side of the puncture needle; during puncture, the puncture needle on one side of the abutting block is completely punctured into the body of a patient, the abutting block and the extension part are reserved on the outer side of the puncture needle, the puncture length is accurate, and the situation that the puncture depth is changed due to unstable manual taking is avoided.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an auxiliary device for treating larger pelvic and abdominal cysts with combined injection under the guidance of ultrasound. Background technique [0002] In recent years, with the rapid development of ultrasound interventional technology, it has become an important part of clinical medicine at home and abroad because of its advantages of minimally invasive, high safety and low price. The advantages of invasiveness, high safety and low price are more and more widely used in clinical practice. [0003] At present, single sclerosing agents such as lauryl alcohol and hypertonic glucose are widely used in clinic for sclerotherapy of cysts, and certain clinical effects have been achieved. However, for larger cysts, the cure rate is low and the recurrence rate is high. The best effect of abdominal cysts is a problem that has been discussed in clinical practice. For the puncture and scle...

Problems solved by technology

[0004] Based on this, the purpose of the present invention is to provide an auxiliary device for the treatment of large pelvic and abdominal cavity cysts with combined injection under the guidance of ultrasound, to solve the problem of puncture and sclerotherapy for acoustically guided pelvic and abdominal cavity cysts. The puncture and flushing trocar for injection has not been improved. The existing puncture needle first uses ultrasound to determine the predetermined puncture point, and then calibrates the length on the puncture needle. The predetermined target is achieved only by marking the length on the puncture needle. Inconvenient control, technical problems caused by large puncture length error
