no. 1 Embodiment approach

[0031] A first embodiment of the present invention will be described with reference to the drawings. figure 1 A schematic diagram of the therapeutic treatment device 20 according to this embodiment is shown. As shown in the figure, the treatment device 20 has a treatment unit 100 , a shaft 260 , an operation unit 270 , and a power supply unit 290 . Hereinafter, for description, the treatment part 100 side is referred to as the distal end side, and the operation part 270 side is referred to as the proximal end side. In the treatment device 20 , the living tissue to be treated is grasped by the treatment unit 100 , and a high-frequency voltage is applied to the grasped living tissue to seal or coagulate the living tissue.

[0032] The treatment part 100 is provided at the front end of the shaft 260 . The treatment unit 100 has a set of forceps that changes relative positions to each other to grasp living tissue. One side of the forceps is called a first gripping member 110 , ...

no. 2 Embodiment approach

[0089] A second embodiment will be described. Here, differences from the first embodiment will be described, and the same parts will be given the same reference numerals and their descriptions will be omitted. Figure 11A A perspective view of the treatment part 100 of this embodiment is shown. also, Figure 11BA cross-section perpendicular to the longitudinal direction of the treatment part 100 is shown, and a cross-sectional view viewed from the front end side of the treatment part 100 is shown. Here, the configuration of the energy application unit is specifically shown.

[0090] Such as Figure 11A with Figure 11B As shown, similarly to the case of the first embodiment, the first holding member 110 is provided with a concave portion 113 . Moreover, the convex part 122 is provided in the 2nd holding member 120. As shown in FIG. In this embodiment, as in the case of the third modified example of the first embodiment, an inclination is provided on the opposing surface ...

no. 3 Embodiment approach

[0099] A third embodiment will be described. Here, differences from the second embodiment will be described, and the same parts will be given the same reference numerals and their descriptions will be omitted. Figure 12A A perspective view of the treatment part 100 of this embodiment is shown. also, Figure 12B A cross-section perpendicular to the longitudinal direction of the treatment part 100 is shown, and a cross-sectional view viewed from the front end side of the treatment part 100 is shown. In this embodiment, the ninth holding member 191 is an ultrasonic applicator. The ninth grasping member 191 has an elongated shape, passes through the shaft 260 , and is connected to an ultrasonic vibration source provided in the operation portion main body 272 . The ninth holding member 191 vibrates longitudinally in its longitudinal direction. Such as Figure 12B As shown, the cross-sectional shape perpendicular to the longitudinal direction of the ninth gripping member 191 i...

Abstract

A therapeutic treatment device (20) is provided with a first holding member (110) and a second holding member (120) that moves relative to the first holding member and holds a biological tissue together with the first holding member. In a cross section including a point at which the first holding member and the second holding member come into contact with the biological tissue, the first holding member and the second holding member are shaped such that when a point on the first holding member closest to the second holding member is a first point and a point on the second holding member closest to the first holding member is a second point, the trajectory of the second point and the line of extension of the trajectory, when the second holding member moves relative to the first holding member, do not pass through the first point.

Description

technical field [0001] The present invention relates to therapeutic treatment devices. Background technique [0002] Mechanical treatment instruments such as staplers, energy application treatment instruments, and the like are known as medical treatment instruments for joining living tissues. When using an energy-applying treatment instrument to join living tissue to living tissue, the living tissues are grasped using a gripping portion composed of a pair of forceps, and energy is applied to the gripping portion to join the living tissues. [0003] For example, Japanese Unexamined Patent Application Publication No. 2012-239899 discloses a technique related to a treatment instrument for surgical operations that easily removes collagen and elasticity by applying electrical energy and physical energy to blood vessels and vascular tissues. Protein extraction for coagulation of blood vessels and vascular tissue. [0004] Generally, when living tissue is joined using an energy-a...
