Problems solved by technology

[0018] Moreover, in the conventional ultrasonic treatment device, the non-contact portion is only provided on a part of the conventional ultrasonic treatment device with respect to the contact portion in contact with the tissue, so the tissue can be sufficiently coagulated at the portion where the non-contact portion is provided, However, with respect to the contact part, the tissue cannot be solidified sufficiently on the side where the non-contact part is not provided
Therefore there is such a situation, that is, in the case of using the conventional ultrasonic treatment device to cut the internal tissue, that is, the blood vessel, after the blood vessel is cut, the blood vessel on the non-contact side is sufficiently coagulated, and the hemostatic property is improved, but in the absence of non-existent One side of the contact part is not coagulated sufficiently, and the hemostasis is reduced

no. 1 Embodiment approach

[0048] figure 1 It is a side view of the assembled state of the whole coagulation and incision apparatus according to the first embodiment of the present invention.

[0049] In addition, in the embodiment of the present invention, the configuration of an ultrasonic coagulation and incision device for coagulating and incising living tissue using ultrasonic waves as energy for treating living tissue will be described.

[0050] Such as figure 1 As shown, the ultrasonic coagulation and incision device 1 of the first embodiment has three assembly units that can be disassembled into three units, namely, the handle unit 2 , the probe unit 3 and the vibrator unit 4 . These 3 units 2~4 can be assembled into figure 1 status shown in .

[0051] The vibrator unit 4 has a handle 4A detachably connected to the handle unit 2 . In this handle 4A, an ultrasonic vibrator (not shown) for generating ultrasonic vibration is built in a cylindrical case 4a covering the outer peripheral portio...

Deformed example 1

[0111] Figure 10 It is a sectional view showing the structure of Modification 1 of the distal end treatment part of the first embodiment.

[0112] Such as Figure 10 As shown, Modification 1 is configured such that the convex portion 15 and the concave portion 14 forming the contact portion 13 are arranged in a vertically opposite direction to that of the first embodiment.

[0113] That is, the gripping member 50b of the jaw unit 5A is formed on a plane perpendicular to the surface facing the treatment portion 10f and the gripping member 5b, for example, on the center line (the centerline of the section of the treatment portion 10f and the gripping member 5b). The convex part 14a which protrudes in the downward direction contacts the part 13.

[0114] Moreover, the treatment part 11f of the vibration transmission member 10 has the contact part 13 formed in the center line, and also has the recessed part 15a for fitting with the convex part 14a and making surface contact.

Deformed example 2

[0118] Figure 11 It is a sectional view showing the structure of Modification 2 of the distal end treatment part of the first embodiment.

[0119] Such as Figure 11As shown, in Modification 2, the structure of the convex portion 15 and the concave portion 14 constituting the contact portion 13 is the same as that of the first embodiment, but the predetermined interval for forming the non-contact portion 16, that is, the gap portion increases as the distance between the convex portion 15 and the concave portion increases. The two sides of 14 increase stepwise.

[0120] For example, the non-contact portion 16 has a first gap portion 16a formed with substantially the same dimension L1 as in the first embodiment, and a dimension L2 formed from the outer side of the first gap portion 16a to the proximal end side with a larger value than the dimension L1. The second gap portion 16b.

[0121] That is, the treatment portion 12f of the vibration transmission member 10 is provided ...

Abstract

This invention provides a coagulation incision apparatus comprising a transfer member for transferring energy for treating a body tissue to the body tissue, a wrapper pipe, into which the transfer member is inserted, and a holding part, supported rotatably to the transfer member in the front end of the wrapper pipe, for holding the body tissue between the holding part and the transfer member. In a face in which the transfer member is opposed to the holding part, a contact part and a non-contact part are provided. In the contact part, when the holding part is rotated to the transfer member side for closing, the transfer member and the holding part are brought into contact with each other over a predetermined length to incise the body tissue held between the transfer member and the holding part. The noncontact part is provided for coagulating the body tissue on both sides of the axis of the direction of the predetermined length in the contact part while providing a predetermined space between the transfer member and the holding part so that the transfer member and the holding part do not come into contact with each other.

Description

technical field [0001] The present invention relates to a coagulation and incision device, in particular, relates to a coagulation device that holds a biological tissue between an ultrasonic probe and a jaw while using ultrasonic waves to incise, resect or coagulate the biological tissue. Cut open the device. Background technique [0002] In recent years, by inserting a slender endoscope into a body cavity, internal organs and the like in the body cavity are observed, and various treatments are performed under endoscope observation as necessary. [0003] As one of the above methods of performing therapeutic treatment under endoscopic observation, a method of performing therapeutic treatment while using a coagulation and incision device is known. When the energy used to treat the living body is, for example, ultrasonic waves, such a coagulation and incision device uses ultrasonic waves to cut, resect, or coagulate the living tissue while holding the living tissue between the...
