Problems solved by technology

[0005] In the existing ablation device, the clamping direction of the ablation device itself is in the same direction as the direction in which the operator holds the device, so the clamping end has only one direction, and the operator can only adjust the position by changing the holding posture. Change the relative position of the clamping end and the target area, so not only the operation is inconvenient, but also the operator's hand needs to bear a large burden

Embodiment Construction

[0084] The present invention will be further described below in conjunction with accompanying drawing.

[0085] Such as Figure 1-Figure 24 As shown, the present invention provides a cryoablation device, which includes a main body 10 , a first sleeve 1 , a second sleeve 2 and a low-temperature working fluid inlet and return structure 3 . One end of the first sleeve 1 extends into the main body 10 and is connected with the main body 10 ; the other end is located outside the main body 10 and is provided with a first clamping portion 11 . The second sleeve 2 runs through the first sleeve 1, so the first sleeve 1 is an outer sleeve, and the second sleeve 2 is an inner sleeve.

[0086] Such as Figure 2a and 3 As shown, one end of the second sleeve 2 extends into the main body 10 and is connected with the main body 10, the other end of the second sleeve 2 is located outside the main body 10, and is provided with a second clamping portion 21, the second clamping portion 21 is op...

Abstract

The invention relates to a cryoablation device, and relates to the technical field of ablation treatment. The cryoablation device comprises a main body, a first sleeve, a second sleeve and a low-temperature working medium inlet and backflow structure, and a rotating device is arranged to rotate under the condition that the position of the main body is relatively unchanged; the first clamping part of the first sleeve, the second clamping part of the second sleeve and the treatment part of the low-temperature working medium inflow and backflow structure located between the first clamping part and the second clamping part can jointly rotate to a preset angle, so that the relative position of the clamping end and a target area can be changed without changing the holding posture, and an operator can conveniently adjust the clamping posture; therefore, not only is the operation more convenient and flexible, but also the burden of the hand of an operator is greatly reduced.

Description

[0001] Cross References to Related Applications [0002] The present invention claims priority to the Chinese patent application CN 202111045567.7 filed on September 7, 2021, entitled "Cryoablation Device", the entire content of which is incorporated herein by reference. technical field [0003] The invention relates to the technical field of ablation therapy, in particular to a cryoablation device. Background technique [0004] Atrial fibrillation, referred to as atrial fibrillation, refers to atrial fibrillation with extremely irregular rhythm, extremely fast frequency and disorder after the complete loss of normal contraction and relaxation of the atrium. Atrial fibrillation can lead to ischemic stroke, thromboembolism, heart failure and other diseases. Atrial fibrillation can be treated surgically. The cryoablation device is used in the field of cardiac surgery, mainly for the treatment of atrial fibrillation, and is one of the essential therapeutic devices for cardia...
