Problems solved by technology

However, since the force used to couple the shock wave source 2 to the patient 12 varies depending on the application, even this measure cannot always ensure that the focal point S coincides with the calibration position C
[0007] In addition to the above image 3 and Figure 4 In addition to the restorable position shift of the focal point S described, there may also be non-recoverable deformations in the case of large expected or unexpected forces, which will cause the focal point S to permanently deviate from the calibration position C and cause serious damage to the patient. bring great risk

Embodiment Construction

[0021] as above through image 3 and Figure 4 As stated, figure 1 The shown shock wave source 2 is mounted on the C-shaped arm 6 via the support arm 4, and can rotate around the nominal position C of the focus of the shock wave source 2 (in this embodiment, the concentric point of the C-shaped arm 6). The calibration position C of the focal point of the shock wave source 2 is located at the image center of the X-ray imaging device 18, and the X-ray imaging device 18 is a C-arm X-ray equipment in this embodiment, wherein, the X-ray receiver 20 and the X-ray tube 22 Arranged on the X-ray C-arm 16 , the concentric point of the X-ray C-arm 16 coincides with the calibration position C of the focal point. The x-ray receiver 20 and the x-ray tube 22 can rotate together about this calibration position C.

[0022] The patient 12 to be treated is placed on the patient examination table 24 , and the shock wave source 2 is coupled with the body surface of the patient 12 through the co...

Abstract

The invention relates to a method for operating a lithotripsy device, whereby a shock wave source (2) is applied to a patient (12) to be treated, said source generating a shock wave that is focused ina focus (S). The invention is characterized by detecting and evaluating at least one force (F) exerted on the shock wave source (2) when it is applied.

Description

technical field [0001] The invention relates to a method for operating a stone crushing device and a stone crushing device operated by the method. Background technique [0002] Lithotripsy is a treatment method that uses focused shock waves to break up stones in the patient's body without surgery. For this purpose, the shock wave source needs to be mechanically coupled to the patient, ie the shock wave source with a connecting bellows (filled with fluid) is placed on the surface of the body. In order to be able to introduce the shock wave into the patient's body with as little loss as possible, the connecting bellows must be in close contact with the body surface without gaps. [0003] To ensure this lossless acoustic coupling, it is known to adjust the force used to place or couple the shock wave source to the patient's body surface by means of the fluid pressure in the connecting bellows. However, depending on the specific anatomy of the patient and the specific penetrat...
