[0073] In this embodiment, according to Figure 1 to Figure 6 A liquid ejecting device as a surgical instrument will be described. figure 1 (a) is a block diagram showing the configuration of the liquid ejecting device. figure 1 (b) is a partially schematic side view showing the configuration of the nozzle of the liquid ejecting device. The liquid ejecting device 1 of the present embodiment is a medical device used in medical institutions, and has a function as a scalpel for incising or excision of an affected area by ejecting a fluid to the affected area.

[0074] like figure 1 As shown in (a), the liquid ejecting device 1 includes a handle 2 . The handle 2 is an instrument that the operator holds and operates when performing an operation. A fluid flow path, that is, an injection pipe 3 is provided on the handle 2 . One end of the spray pipe 3 is provided with a nozzle 4 serving as a liquid spray opening for spraying a fluid. The other end of the injection pipe 3 is pro...

Abstract

Provided is a liquid spray device with which the scattering of biological tissue, such as cells, which has been excised or disintegrated by means of a sprayed pulse flow, can be prevented. The invention is provided with a supply pipe 23 that sprays, from a nozzle 4, a pulse-like first liquid 12 that is supplied from a spray pipe 3, and supplies a second liquid 31 from the supply pipe 23 to the vicinity of the nozzle 4. The invention is further provided with a suction opening 15 that is disposed near the nozzle 4, and a suction pump 18 that is connected to the suction opening 15 via a suction pipe 14 and suctions in the first liquid 12 and the second liquid 31.

Description

technical field [0001] The present invention relates to liquid ejection devices and surgical instruments. Background technique [0002] Medical equipment that directs jetted fluid to an affected area for treatment has been in use. For example, a liquid ejecting device described in Patent Document 1. Accordingly, the liquid ejection device increases or decreases the volume of the fluid chamber supplied with liquid such as physiological saline by driving the piezoelectric element. As a result, a pulsating flow (pulse flow) is formed in the fluid chamber, and the liquid ejection device ejects a pulsating flow of physiological saline or the like from the ejection tube. [0003] The liquid injection device is used as a medical scalpel, for example, and can inject a pulse flow such as physiological saline solution toward a living body to excise or crush the living body.
