Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the technical deficiency that the tail of the puncture needle in the cryosurgical treatment system cannot accept the laser points emitted by the puncture guide, and to provide a puncture needle for the cryosurgical treatment system with reasonable structure, convenient use and simple operation The puncture positioning needle holder solves the problem of "blind puncture" of percutaneous puncture under CT during surgery due to the failure of the cryotherapy system to use the numerical control puncture guide

Embodiment Construction

[0016] Such as figure 1 As shown in the concave part of a needle holder for cryotherapy system puncture according to the present invention, the puncture needle of the cryotherapy system is placed in the plastic tube groove 4 and the needle tube groove 5 of the concave part, and the convex part is covered. After making the four buckle protrusions 8 of the convex part correspond to the four buckle fixing grooves 3 of the concave part, push the convex part down, and the convex part and the concave part will be tightly fastened, and the cryogenic freezing The puncture needle of the treatment system is fixed inside, and the puncture needle of the low-temperature cryotherapy system is integrated with the present invention.

[0017] The operator holds the needle holder, places the puncture needle tip of the cryotherapy system on the needle entry point on the skin, and aligns the circular mark 6 on the top of the needle holder with the laser spot of the numerically controlled puncture...

Abstract

The invention relates to a needle holder (1) for puncture of a low temperature cryosurgery therapy system. The needle holder (1) comprises two basic structures, namely a concave part (2) and a convex part (3) which are used for fixing a puncture needle of the low temperature cryosurgery therapy system. When paracentesis for treating thoracic cancer, abdominal tumors and the like of the low temperature cryosurgery therapy system is implemented, the concave part and the convex part are sleeved on the puncture needle and are buckled, a circle center point at the top of the concave part coincides with a laser point under the guiding of a laser point of a puncture guiding instrument, a straight puncture line formed by the circle center point and a puncture needle point inserting point on the skin is formed, and the paracentesis is finished simply and quickly. The needle holder is reasonable in structure, convenient to use and simple in operation, and reduces and avoids paracentesis complications including pneumothorax, haemorrhage and the like caused by multiple-time 'blind puncture' performed through the low temperature cryosurgery therapy system.

Description

technical field [0001] The invention relates to a needle holder for puncture guidance of a puncture needle of a cryogenic surgery treatment system. Background technique [0002] The low-temperature cryotherapy surgery system is a minimally invasive low-temperature cryoablation medical device developed abroad. Some hospitals in my country have introduced this device in recent years for intratumoral destructive surgery for malignant solid tumors. It has small trauma, good curative effect, and fast recovery. Features. Because the operation is performed under the guidance of CT after percutaneous puncture and then cryotherapy, if not under the guidance of the puncture guide, the operator estimates the puncture angle based on CT images and clinical experience to perform percutaneous puncture. Percutaneous puncture in the "blind puncture" state brings pain to patients with complications such as pneumothorax and bleeding caused by multiple punctures. [0003] At present, the domes...
