High cutting force medical water jet scalpel and application thereof

Abstract

The invention discloses a high cutting force medical water jet scalpel and an application thereof. The high cutting force medical water jet scalpel is used to cut biological tissue. The high cutting force medical water jet scalpel comprises a high pressure pipe, a liquid nozzle and a material mixing pipe, wherein a mixed material nozzle is arranged at one end of the material mixing pipe, a material mixing cavity is formed in a portion of the material mixing pipe, between the liquid nozzle and the mixed material nozzle, and a feed pipe which supplies biocompatibility particles into the material mixing cavity is arranged on the side wall of the material mixing cavity. When the high cutting force medical water jet scalpel is used, high pressure liquid enters the liquid nozzle through the high pressure pipe so as to form liquid jet flow, the biocompatibility particles added in the material mixing cavity through the feed pipe are continuously sucked into the material mixing cavity under action of negative pressure generated by the liquid jet flow, and then mixed with the high pressure liquid, and finally mixed material liquid jet flow formed by the biocompatibility particles and the high pressure liquid is sprayed out through the mixed material nozzle. Due to action of the biocompatibility particles in the mixed material liquid jet flow, the mixed material liquid jet flow generates cutting force several multiples or tens of multiples of cutting force generated by pure liquid high pressure jet flow, the purpose of incising and separating the human tissue can be achieved by using the high cutting force medical water jet scalpel, and furthermore the high cutting force medical water jet scalpel is wide in use range, and meets multiple surgical operation demands.

Description

technical field [0001] The invention is used in the technical field of medical equipment, and in particular relates to a medical water jet with high cutting force and its application. Background technique [0002] Conventionally, medical waterjet is used for selective cutting of human soft tissue, requiring only low cutting force. Therefore, the existing medical water jets all use fluid media such as pure water or physiological saline, which cannot produce high cutting force. [0003] The use of water jets to generate high cutting forces is generally limited to industrial waterjet applications, which are achieved by adding industrial abrasives to the liquid. This implementation is generally not suitable for medical water jets for medical operations, because in medical applications, there are physiological or physiological compatibility requirements for the addition of abrasives. [0004] Therefore, in the medical field, it is necessary to add abrasives by introducing indus...
