[0058] Below, refer to Figure 1 to Figure 24 The first embodiment of the present invention will be described.

[0059] figure 1 It is a perspective view showing the medical clip 1 of the first embodiment. The medical clip 1 includes a frame 10 and an elastic member 20 .

[0060] figure 2 It is a figure which shows the frame 10 of the medical clip 1. exist figure 2 In , the dashed-two dotted line indicates the shape of the medical jig 1 . The frame 10 includes a pair of gripping portions 12 composed of a first gripping portion 12A and a second gripping portion 12B, and a pair of gripping portions 12 connected, that is, connecting the first gripping portion 12A and the second gripping portion 12B. Connecting part 14. In addition, in this embodiment, the frame 10 is formed by bending a rigid plate-shaped member.

[0061] The pair of gripping parts 12 are formed so as to extend from the front end part 12f to the rear end part 12b, and are provided to be separated from ...

[0094] exist Figure 12 In step S1 shown, the medical jig 1 is attached to the ultrasonic probe 50 and the forceps 60 used as the treatment tool 40 in this technique. First, the amount of protrusion of the ultrasonic probe 50 from the tip of the guide sheath 30 is set in advance. The medical clip 1 is attached to the insertion portion 51 at a position corresponding to the protrusion amount. Next, the amount of protrusion of the forceps 60 from the tip of the guide sheath 30 is set. The amount of protrusion of the pliers 60 is set to be the amount of protrusion from the tip of the guide sheath 30 at the position of the ultrasonic vibrator 57 of the ultrasonic probe 50 and the amount of protrusion from the tip of the guide sheath 30 at the position of the gripping portion 68 of the pliers 60 . The amount of protrusion is equal. Another medical clip 1 is attached to the insertion portion 61 at a position corresponding to the protrusion amount.

Abstract

This medical clip is provided with: a frame having a pair of knob parts formed so as to extend from a front end part to a rear end part and provided so as to be separated from each other, and a connecting part for connecting the knob parts so that front end parts of the knob parts can approach and separate from each other; and an elastic member provided between the front end parts of the knob parts. The elastic member has: an open hole having an inside diameter smaller than the outside diameter of a treatment tool, the open hole being formed through the elastic member along a direction intersecting with the plane passing through the front end parts and rear end parts of the knob parts; and a slit having a gap smaller than the inside diameter of the open hole, the slit being communicated with the open hole throughout the entire length of the open hole and formed so as to extend to an external peripheral surface of the elastic member. The slit is configured so as to be able to open and close by the approaching and separation of the front end parts of the knob parts.

Description

technical field [0001] The invention relates to a medical clamp and a treatment appliance system. [0002] This application claims priority based on Japanese Patent Application No. 2015-248984 for which it applied to Japan on December 21, 2015, The content is used here. Background technique [0003] Conventionally, when endoscopically performing a biopsy on, for example, a peripheral lesion of a lung field, the target site may be located in a bronchiole. In such a case, a technique is known in which a guide sheath having a diameter smaller than that of the endoscope is inserted into the channel of the endoscope, and the guide sheath is protruded from the tip of the endoscope to be placed near the target site. , insert the disposal instrument into the guide sheath for biopsy. In this technique, the treatment instrument inserted into the guide sheath may be replaced with another treatment instrument. If the insertion amount with respect to the guide sheath is mistaken when ...
