Description

【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、超音波振動で生体内の前立腺を切除する等
の処置を行なう超音波振動処置装置の改善に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in an ultrasonic vibration treatment device that performs treatment such as resection of the prostate in a living body using ultrasonic vibration.

〔従来の技術〕[Conventional technology]

従来より、経尿道的な前立腺の切除術には、患部組織を
高周波電流で焼灼して切除することが行なわれている。Conventionally, in transurethral resection of the prostate, the affected tissue is cauterized and removed using high-frequency current.

しかし、こうした切除は焼灼した生体組織が変性白化す
るために、切除範囲の判別が困難で正常組織まで切除し
てしまう危険をもつ。しかも、誤って部組°織に電極が
触れてしまうと、患部が反射動作を起こして穿孔等を引
起こし出血多量が起こるおそれがあった。However, since such resection causes degeneration and whitening of the cauterized living tissue, it is difficult to determine the extent of resection, and there is a risk that normal tissue may also be resected. Moreover, if the electrode accidentally touches a tissue, there is a risk that the affected part will cause a reflex action, causing perforation or the like, resulting in profuse bleeding.

そこで、最近、超音波振動を使った超音波振動処置装置
で切除することが行なわれるようになってきた。これに

触から、超音波振動を患部組織に伝達して切除し、その
後、切除された組織を挿入部先端の吸引孔、・吸引路を
通じ体外へ排出するようにしている。Therefore, recently, an ultrasonic vibration treatment device using ultrasonic vibration has been used to perform resection. For this purpose, a structure is used in which an ultrasonic transducer is connected to the base of an insertion section made of a pipe, and a suction sardine is formed inside the insertion section. Then, when the insertion part comes into contact with the affected tissue, ultrasonic vibrations are transmitted to the affected tissue to ablate it, and the excised tissue is then expelled from the body through the suction hole and suction path at the tip of the insertion part. .

〔発明が解決しようとする問題点〕[Problem that the invention seeks to solve]

ところが、こうした処置装置は確かに超音波振動を使う
ために、生体組織の変性白化がなく切除範囲の判別が容
易となる。穿孔等が発生しない（高周波電流が流れない
ため）ものの、組織の排出時、吸引力により出血が起こ
る問題があった。However, since these treatment devices do use ultrasonic vibration, there is no degeneration or whitening of living tissue, and the resection range can be easily determined. Although no perforation or the like occurs (because no high-frequency current flows), there is a problem in which bleeding occurs due to the suction force when the tissue is expelled.

この発明はこのような問題点に着目してなされたもので
、超音波振動で切除した際に起こる出血を止めることを
目的とする。This invention was made in view of these problems, and its purpose is to stop bleeding that occurs during resection using ultrasonic vibration.

〔問題点を解決するための手段及び作用〕この装置では

５で出血部を止血することにある。[Means and effects for solving the problem] In this device, a hemostasis means 5 is provided at the distal end of the insertion section 4, and the hemostasis means 5 stops the bleeding at the bleeding site.

Apply to the prostate area. Then, by applying ultrasonic vibrations from the ultrasonic transducer 2 and applying suction force, the ultrasonic vibrations transmitted to the affected area will ablate the affected tissue, and the excised tissue will be suctioned from the suction hole 4a. It is expelled from the body through the suction channel.
