Cryotherapy probe with combined ultrasonic probe for oncotherapy

Abstract

The invention discloses a cryotherapy probe with a combined ultrasonic probe for oncotherapy, which comprises a treatment probe and a combined ultrasonic probe, wherein the combined ultrasonic probe comprises a concave cup-shaped housing with a center hole, a concave cup-shaped sink table positioned in the concave cup-shaped housing, a hollow cylinder body arranged at the center of the bottom surface in the sink table, and an ultrasonic probe arranged in an ultrasonic probe supply chamber, wherein a cavity arranged between the housing and the sink table, vertical rib plates are connected and radially distributed on the outer cylindrical surface of the cylinder body and extend into the inner side wall of the sink table, the ultrasonic probe supply chamber is enclosed among the vertical ribplates, a probe angle regulation and connection port is connected with the rear end of the ultrasonic probe and used for regulating an ultrasonic transmitting surface angle; the ultrasonic probe is respectively connected with an ultrasonic generator through a lead; and a probe rod of the treatment probe penetrates through a center hole and an inner hole of the hollow cylinder body. The invention ensures that tissues are not frozen when reaching a freezing point by using a heating effect of large-power ultrasonic and enlarging tissue freezing condensate depression, thus non-freezing target tissues around a freezing probe are effectively protected from being frozen due to leakage cold during cryotherapy.

Description

technical field [0001] The present invention relates to a low-temperature cryotherapy probe for tumor treatment, in particular to a low-temperature cryotherapy probe with an ultrasonic probe for tumor treatment; The principle of ice crystal nucleation is a low-temperature cryotherapy probe that protects the tumor target site, which not only effectively protects healthy tissue, but also does not hinder the cryo-killing treatment of the tumor site. Background technique [0002] Cryosurgery quickly freezes diseased tissues (such as tumors) through rapid freezing and rewarms them, causing a series of irreversible damage to the treatment site to achieve the goal of eliminating tumors. It is a new method for effective treatment of tumors emerging in recent years . In this treatment method, a cryoprobe (cold knife) is usually inserted into the lesion to be treated to introduce cold energy to perform the operation. However, in the process of directing cold energy to the diseased a...

AI Technical Summary

Problems solved by technology

With the current existing technology, even if the cryoprobe shaft is provided with a vacuum insulation layer, there will inevitably be cold leakage. In the actual treatment process, this unexpected cold loss often causes Brings about cryo-destruction of normal tissue adjacent to the cryoprobe shaft
