As a surgical device that uses ultrasonic mechanical vibration, an ultrasonic probe is connected to an ultrasonic vibration source, and the mechanical vibration of the ultrasonic frequency at the tip of the ultrasonic probe crushes cells, blood clots, calcium lumps, etc. death,
Through the lumen of the ultrasound probe, the disrupted cells
Devices for suctioning and removing blood clots, calcium lumps, etc. have been known for some time (for example, Japanese Patent Application Laid-Open No. 60-5139 and Japanese Patent Application Laid-open No. 49-21989). However, since the ultrasonic probes of these devices do not have flexibility, they cannot be used for curved tubular organs in living bodies such as blood vessels.

However, this method has poor operability because the ultrasonic probe is not flexible, and the areas to which it can be applied are limited.

However, although this method is effective for stones fixed on the inner wall of the body cavity and coral-shaped stones embedded in the renal calyx, ultrasonic vibration is effective for stones in the renal pelvis that are not fixed. The ultrasound probe cannot be brought into contact with the ultrasound probe while using the inner lumen as a suction tube to aspirate the stone, as is the case with a tubular probe.
There was a risk of injury to the tissues within the renal pelvis.

Previously, he invented a surgical tool in which an ultrasonic probe made of a flexible linear transmitter was installed inside the lumen of a flexible tube, and disclosed it in Japanese Patent Application Laid-Open No. 61-272045. Since the ultrasonic probe is a linear body, it is necessary to provide a suction passage and a medicine injection passage separately in order to carry out suction and injection of medicine. For this reason, the diameter of the flexible tube becomes large, making it difficult to insert it into small blood vessels and the like, and there is a risk of damaging the inner wall of the blood vessel.

The present invention aims to solve these problems of conventional surgical tools, and involves fixing a metal pipe to the tip of an ultrasonic transmitting device, and attaching a flexible material to the tip of the metal pipe. By attaching multiple flexible linear transmitters, there is a problem that the scope of application is limited due to the lack of flexibility, which is a drawback of metal tubular probes, and probes made of linear bodies This is intended to solve the problem of the disadvantage that the shape is large due to the provision of separate passages for drug injection and suction, making it difficult to insert into narrow living body lumens such as blood vessels. Furthermore, it is an object of the present invention to provide a surgical tool equipped with a tubular probe made of materials and properties suitable for such purposes.

The linear transmission body 12 is connected by an appropriate method such as embedded adhesive or embedded welding. Since the inner hole of the probe 6 extends to the tip surface of the metal pipe 11,
Foreign matter crushed near the tip of the linear transmission body 12 is removed by suction from the tip of the metal pipe 11. In addition, the connection part 1 provided integrally with the metal pipe 11
0 is an ultrasonic transmitter 4 using screws, welding, etc.
It is connected to the fixture 5 of.

The linear transmitter 12 may be a single wire made of these metals, but since it is preferable to have excellent flexibility in use, it may be a string-like body made by twisting or braiding a plurality of ultrafine wires made of the metals. Impregnated with synthetic resin or
Alternatively, it is preferable to use one in which both the inner and outer surfaces are coated and integrated. The synthetic resin to be impregnated or coated must have heat resistance and flexibility that will not cause decomposition or melting due to the heat generated by the ultrasonic vibration of the base material made of metal wire. Examples of such synthetic resins include fluororesins, polyamides, polyesters, polyimides, polyetherimides, polyethersulfones, and the like. In addition, when the amount of resin to be impregnated or coated is small, epoxy resin, polyester resin,
Thermosetting resins such as polyurethane resins can also be used.

位置が離れすぎるので好ましくない。 To describe one example of how to use the surgical tool according to the present invention, for example, when used to remove a stone formed in the renal pelvis, the entire probe is housed in the hole of the endoscope and placed on the surface of the patient's body. It is inserted percutaneously into the kidney. When the tip reaches a predetermined position, the linear transmitter 12 is pushed out of the hole of the endoscope and bent to transmit ultrasonic waves to the target stone and crush it. In this way, the rigidity of the metal pipe allows for smooth insertion into the body, and the flexibility of the linear transmitter attached to the tip allows for smooth insertion during stone fragmentation. This provides the advantage of being able to precisely target the stone. In this case, the length of the metal pipe 11 is usually in the range of about 40 to 60 cm, and the length of the linear transmitter 12 is preferably about 3 to 4 cm. This is not preferable because the position where the calculus is crushed and the position of the tip of the metal pipe serving as the suction hole are too far apart.
