Embodiment Construction

[0025] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0026] Such as figure 1 As shown, this embodiment provides a dual-catheter ultrasonic lithotripter, including a driving handle 1, and an inner catheter 2 connected to the driving handle 1 and driven by the driving handle 1 to perform torsional vibration, wherein the inner catheter 2 The outer casing is provided with an outer conduit 3, and the inner conduit 2 drives the outer conduit 3 to perform longitudinal vibration through a transmission part.

[0027] In this embodiment, through the arrangement of the inner and outer conduits, one of which performs torsional vibration and the other performs longitudinal vibration, the combination of torsional vibration and longitudinal vibration is applied to the stone crushing process, improving the stone crushing efficiency and reducing the It reduces the da...

Abstract

The invention relates to the technical field of medical apparatuses and instruments, in particular to a double-conduit ultrasonic lithotripter. The double-conduit ultrasonic lithotripter comprises a driving handle and an inner conduit connected with the driving handle and performing torsional vibration under the driving of the driving handle, wherein the outer side of the inner conduit is sleeved with an outer conduit, and the inner conduit drives the outer conduit to perform longitudinal vibration through a driving part. In the double-conduit ultrasonic lithotripter, the inner conduit and the outer conduit are arranged and are used for torsional vibration and longitudinal vibration respectively. The double-conduit ultrasonic lithotripter is applied to the stone breaking process by combining the torsional vibration and longitudinal vibration, the stone breaking efficiency is improved, the damage rate of a tool head is reduced, and the impact force and structure damage in the stone breaking process can be reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a double-catheter ultrasonic lithotripter. Background technique [0002] With the acceleration of the pace of human life and changes in diet structure, stone diseases have become a common and frequently-occurring disease. [0003] At present, ultrasound is generally used for lithotripsy followed by stone expulsion. Among them, in vitro ultrasonic lithotripsy has certain side effects, which may damage renal function, and has a high recurrence rate. Therefore, in vivo ultrasonic lithotripsy has become the first choice for lithotripsy because it is less harmful to the human body. However, the existing ultrasonic lithotripsy technology has a large impact force, which will cause a certain degree of tissue damage, and the ultrasonic lithotripter has problems such as serious wear of the tool head, low lithotripsy efficiency, and long lithotripsy time. [0004] In view of t...
