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.

Be further used as the improvement of technical solution of the present invention, described biocompatible particles comprises Calcium phosphate biomaterials granule.
Beneficial effect of the present invention: when this high cutting force medical water jet uses, high pressure liquid is injected in high-voltage tube, biocompatible particles is injected in charge pipe, high pressure liquid enters fluid injector by high-voltage tube, form liquid jet, the biocompatible particles added by charge pipe, under the suction function that liquid jet produces, constantly suck batch mixing chamber, mix with high pressure liquid, the final batch mixing liquid jet that formed sprays from batch mixing nozzle.Due to the effect of biomaterial granule in batch mixing liquid jet, batch mixing liquid jet flow ratio simple liquid high pressure jet stream produces several times to tens times cutting force, can solve medical water jet to the large cutting of tissue of hardness, the problem of separation, the scope of application is wider, meets more surgical operation needs.Meanwhile, biomaterial granule has good biocompatibility, reduces the untoward reaction that human body produces because of the existence of foreign body in vivo, and, when carrying out the cutting of certain class loading, adopting corresponding biomaterial, the quickly-healing of wound surface can be increased.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is embodiment of the present invention structural representation.
Detailed description of the invention
With reference to Fig. 1, that show the concrete structure of the preferred embodiment of the present invention.To the construction features of the present invention each element be described in detail below, and if be described to direction (upper and lower, left and right, before and after) time, be with the structure shown in Fig. 1 for reference to describing, but actual user of the present invention is to not limiting to so.
The invention provides a kind of high cutting force medical water jet, for the cutting of biological tissue, comprise the high-voltage tube 1, fluid injector 2 and the mixing tube 3 that connect successively, described mixing tube 3 shrinks in the aperture, one end away from fluid injector 2 and forms batch mixing nozzle 4, the dead in line of described batch mixing nozzle 4 and described fluid injector 2.Described mixing tube 3 forms batch mixing chamber 31 between described fluid injector 2 and batch mixing nozzle 4, and the sidewall in described batch mixing chamber 31 is provided with the charge pipe 5 supplying biocompatible particles in described batch mixing chamber 31.During use, high pressure liquid is injected in high-voltage tube 1, biocompatible particles is injected in charge pipe 5, high pressure liquid enters fluid injector 2 by high-voltage tube 1, form liquid jet, the biocompatible particles added by charge pipe 5, under the suction function that liquid jet produces, constantly suck batch mixing chamber 31, mix with high pressure liquid, the final batch mixing liquid jet that formed sprays from batch mixing nozzle 4.Due to the effect of biomaterial granule in batch mixing liquid jet, batch mixing liquid jet flow ratio simple liquid high pressure jet stream produces several times to tens times cutting force, can solve medical water jet to the large cutting of tissue of hardness, the problem of separation, the scope of application is wider, meets more surgical operation needs.
