Embodiment approach

[0044] figure 1 It is an explanatory diagram showing the configuration of the surgical device 10 as one embodiment of the present invention. The surgical device 10 of the present embodiment is used in a medical institution, and has functions of an electric scalpel, a liquid jet scalpel, and an aspirator. The surgical device 10 includes a handle 20 , a high-frequency power supply unit 100 , a liquid supply unit 200 , a suction device 300 , and a control unit 400 .

[0045] The handle 20 includes a body 30 , an elongated handle 40 extending from the body 30 , and a treatment unit 50 designed at the front end of the handle 40 . In the following description, the treatment part 50 side in the extending direction of the long handle 40 is called "front side", and the body 30 side in the extending direction of the long handle 40 is called "rear side". In addition, the front side and the rear side may only be referred to as "front" and "rear".

[0046]The treatment unit 50 constitut...

Deformed example 1

[0072] In the above-described embodiments, liquid is used as the fluid ejected from the surgical device 10 . On the other hand, in a modified example, gas may be used as the fluid ejected from the surgical device 10 . In addition, it may be sprayed in a state where a liquid and a gas are mixed.

Deformed example 2

[0074] In the above-described embodiment, the liquid ejection tube 210 is housed in the first clamping piece 53 as a fixed part, and the suction tube 320 is housed in the second clamping piece 54 as a movable part. On the other hand, in a modified example, the suction tube 320 may be accommodated in the first clamping piece 53 as the fixed portion, and the liquid ejection tube 210 may be accommodated in the second clamping piece 54 as the movable portion.

Abstract

An operation instrument (10) includes an electric surgical knife, a fluid ejection surgical knife, and a gripper mechanism (52). The gripper mechanism including a pair of gripper strips (53, 54) configured to be openable and closable so as to grip a living tissue and at least one of which is a movable portion. The gripper strips (53, 54) each are provided with an electrode (110) for the electric surgical knife. An ejection opening (212) for the fluid ejection surgical knife is formed in a first gripper strip (53), and the ejection opening is formed at a position (53b) retracted from an end portion on a distal end side of the electrode.

Description

technical field [0001] The present invention relates to a surgical device. Background technique [0002] As a surgical device, there is known a liquid jet scalpel that performs incision, excision, etc. of living tissue by continuously jetting liquid (for example, water) at high speed. In addition, an electric scalpel is also known as a surgical device mainly for hemostasis. In the surgical equipment described in Patent Document 1, there is described a configuration in which a single liquid jet scalpel and a bipolar electric scalpel are combined. With this configuration, it is possible to save time for replacing the surgical equipment with other surgical equipment during surgery. [0003] The surgical device described in Patent Document 1 is in the shape of forceps, and holds living tissue for treatment. However, when the living tissue is clamped and energized, burned living tissue may adhere to the tip of the forceps. The electrodes for the electric scalpel and the liquid...
