Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to a resectoscope that visually captures and treats diseased areas such as the prostate and bladder.

[Prior Art] A resectoscope is known as a medical device that visually detects and treats diseased areas such as the prostate and bladder.

In this type of resect scope, an optical viewing tube and a probe that vibrates ultrasonically as a treatment tool are inserted into a scope body such as a sheath, and the probe is attached to the scope body along with the entire vibration system including a vibrator. By sliding it, it protrudes and retracts from its distal end surface, and the various treatments described above are performed.

[Problems to be solved by the invention] Conventionally, in a resectoscope with such a structure,
The operator used one hand to support the optical viewing tube together with the scope body, and used the other hand to slide the probe while holding the vibration system to which the probe was connected. As a result, the surgeon's hands are occupied when operating the probe and performing surgery, making it impossible to perform any other operations during the surgery, which is extremely inconvenient.

An object of the present invention is to provide a resect scope that allows the user to slide the probe with one hand while holding the sheath body.

[Means and effects for solving the problems] This invention has the following features:
The scope body 1, the first finger hook 7 provided at the rear end of the scope body 1, and the obliquely bent rear portion that is slidably inserted into the scope body 1 are attached to the scope body 1. A probe 5 is detachably attached to the probe 5 and is provided with a second finger hook 16 at the rear thereof.
The probe 5 can be slid by hooking the fingers of one hand on the first and second finger hooks 7.16, respectively.

[Example] An embodiment of the present invention will be described below with reference to the drawings.

The resect scope shown in FIG. 1 includes a sheath 1 as a scope body. At the rear end of this sheath 1 is a cap 2.
A pair of through holes 3 are bored in the base 2. An optical viewing tube 4 is slidably inserted into one of these through holes 3, and a probe 5 is slidably inserted into the other. An eyepiece section 4a is provided at the rear end of the optical viewing tube 4 protruding from the base 2, and the rear end of the probe 5 is also formed into an obliquely bent bent section 5a. Child 6 is connected.

Therefore, the probe 5 is made to vibrate ultrasonically by the vibrator 6.

The cap 2 is integrally provided with a first finger hook 7. As shown in FIG. 5, the first finger rest portion 7 is provided with a hole 12 on which three fingers, the index finger 8, the middle finger 9, and the ring finger 11 are hung. Further, a pair of guide rods 13 extend rearward from the first finger hook portion 7.

A case 14 housing the vibrator 6 is slidably attached to these guide rods 13.
The base of the thumb 15 is the second part on which the root part can be hung.
A protrusion 16 is provided as a finger rest. That is, the case 14 is provided with a pair of boss portions 17,
These boss portions 17 are slidably fitted into the guide rod 13. Further, a stopper 18 is screwed into the end face of the guide rod 13, thereby preventing the case 14 from coming off the guide rod 13. Furthermore, the guide rod 13' has a case 1.
A spring 19 is provided which biases the spring 4 in the extraction direction.

When using a resectoscope with such a structure, the operator should attach the index finger 8, middle finger 9, and ring finger 11 of one hand to the holes in the first finger rest 7, as shown in FIG. 12 and the base of the thumb 15 on the projection 16, which is the second finger rest, the entire resect scope can be held with one hand.

In order to make the distal end of the probe 5 protrude from the distal end surface of the sheath 1 while holding the resectoscope with one hand, use the finger hook with one hand with each finger hooked on the hole 12 and the protrusion 16. Hold it. Then, as shown in FIG. 3, the case 14 moves forward along the guide rod 13 against the biasing force of the spring 19, and the probe 5 moves in conjunction with this, and its tip touches the sheath 1.
protrudes from the tip of the Also, if you open one of your gripped hands, the case 14 will spring up against the spring 19 as shown in FIG.
Since the probe 5 retreats due to the restoring force, the tip of the probe 5 protruding from the tip surface of the sheath 1 is recessed in conjunction with this.

In other words, since the surgeon can move the probe 5 forward and backward while holding the resectoscope with only one hand, he or she can perform various tasks incidental to the surgery with the other hand during the surgery. It's convenient. In addition, the probe 5 can be moved forward and backward by simply holding or opening one hand, so the operation is easy.

Furthermore, the rear end portion of the probe 5 is formed into a bent portion 5a,
Since the vibrator 6 is connected to the end thereof, the case 14 housing the vibrator 6 and the eyepiece portion 4a of the optical viewing tube 4 are prevented from interfering with each other. In other words, since the optical viewing tube 4 and the probe 5 can be placed close to each other, the entire system can be configured compactly.

Note that the present invention is not limited to the above-mentioned embodiment; for example, the probe may be one that uses high-frequency current to treat the lesion instead of using ultrasonic vibration.

[Effects of the Invention] As described above, the present invention provides a first finger hook at the rear end of the scope body, allows the probe to be slidably inserted into the scope body, and has an obliquely bent rear part. is detachably attached to the scope body, and a second finger rest is provided at the rear of the scope body. Therefore, by hooking the fingers of one hand onto the first and second finger hooks and holding the entire scope with one hand, and in this state, grasping or opening that hand, the probe can be moved forward or backward. This allows for improved operability compared to the previous model, which required the use of both hands. Furthermore, since the rear end of the probe is bent, various instruments provided at this rear end are less likely to interfere with the eyepiece of the optical viewing tube. therefore,
Since the optical viewing tube and the probe can be placed sufficiently close to each other, the overall structure can be made more compact. Furthermore, since the probe can be removed from the scope body, it is very convenient to replace or repair the probe.
