Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a laser scalpel attachment, and more particularly to an improvement on a conventional laser scalpel attachment by providing a smoke evacuation means for disposing of smoke generated during surgery.

As is well known, laser surgery uses a light guide path such as a manipulator to transmit powerful laser light emitted from a laser resonator.
It is carried out by guiding it freely to the surgical field, irradiating it as appropriate, and cauterizing the affected area with its high heat.

Here, the laser beam is converged and irradiated to one point by a condensing lens at the tip of the manipulator to incise and remove the affected area, and irradiated as a defocused beam to effectively evaporate the affected area. be done.

However, when the laser beam is irradiated to cauterize the affected area, the burning odor and smoke emitted by the body are very unpleasant.

Additionally, in the field of otorhinolaryngology, there is a risk that patients may have difficulty breathing due to the smoke.

Therefore, during laser surgery, a smoke suction device is usually used at the same time to quickly remove this smoke.

That is, in this method, the suction port of a smoke suction device is placed near the affected area by a person attending the surgery, such as an assistant doctor or a nurse, and the smoke generated during the surgery is sucked out at any time.

However, such a method is not at all desirable because it not only burdens the hands of those attending the surgery who are involved in operating the smoke suction device, but also has the risk of interfering with the surgeon's work.

Therefore, the following new method has been devised to overcome the deficiencies of the conventional method.

That is, the probe disclosed in the specification of Japanese Utility Model Application Publication No. 55-2385 (referred to as an adapter in the specification) is one such probe.

This probe is connected to the tip of the manipulator, and has the role of a guide for laser light converged by a condensing lens, and also has the configuration and function described below.

That is, a smoke inlet is provided on the inner wall of the distal end of the adapter for sucking smoke generated during surgery, and the smoke inlet is in communication with a smoke outlet projecting from the outer wall of the adapter.

Therefore, by connecting a hose extended from the suction device to the exhaust port, smoke generated during surgery can be immediately suctioned and removed.

In addition, there is a great advantage that smoke removal does not take much time for those attending the surgery and does not interfere with the work of the surgeon.

However, during laser surgery, it is customary to replace the probe as appropriate depending on the circumstances during the surgery or the condition of the affected area, and therefore it is common to have probes in various forms depending on the purpose.

Moreover, when replacing the probe during surgery, it goes without saying that it is desirable to be able to replace the probe quickly.

However, the method described in the above specification has the following disadvantages.

That is, in this system, as described above, an outlet is provided on the outer wall of the probe, and a hose from a smoke suction device is connected to the outlet to exhaust smoke.

Therefore, when replacing the probe during surgery, it is necessary to first remove the hose, attach a new probe, and then reconnect the hose.

This is inconvenient and may even slow down the surgical process, especially in cases where speed is required.

Therefore, the present invention aims to eliminate the deficiencies of the conventional smoke evacuation system, and relates to a laser beam scalpel attachment characterized by the configuration described below.

That is, in a laser scalpel attachment that includes a lens house having a condenser lens and a probe attached to the tip of the lens house, a first smoke inlet is provided on the inner wall side of the tip of the probe, and a first smoke inlet is provided on the inner wall side of the tip of the probe. A first outlet provided at the base end of the probe and the first suction port communicate with each other.

Further, a second suction port is provided at the tip of the lens house and communicates with a second discharge port provided on a side wall of the lens house.

Here, when connecting the probe and the lens house,
The second suction port and the first discharge port are connected to each other.

That is, this corresponds to communication between the first suction port at the tip of the probe and the second discharge port provided on the side wall of the lens house.

Therefore, by connecting a hose extended from the smoke suction device to the second outlet, smoke generated during surgery can be removed by suction.

Hereinafter, embodiments of the present invention will be described in detail based on the attached FIGS. 1 to 3.

FIG. 1 is a schematic cross-sectional view of one embodiment of the present invention.

Here, one end of a lens house 2 is connected to the tip of the manipulator 1.

A lens holder 4 is fixed within the lens house 2, and a condensing lens 3 is held in the holder 4.

A probe 8 is attached to the lock nut 1 at the other end of the lens house 2.
3, they are connected to each other so that they can be attached and detached at any time.

On the other hand, a first smoke inlet 5 is provided on the inner wall side of the tip of the probe 8 .

Further, a cylindrical first discharge port 10 is formed on the side of the base end, and an O-ring 7 made of an elastic body is held therein.

The first suction port 5 and the first discharge port 10 are connected to the probe 8.
They are communicated by an air pipe 12 formed in the wall of the .

Although not shown, it is also possible to make the inside of the wall of the probe 8 hollow to allow the suction port 5 and the discharge port 10 to communicate with each other.

A second suction port 11 into which the first discharge port 10 is fitted is formed at the tip of the lens house 2 .

The second suction port 11 is formed to communicate with a second discharge port 6 provided on the side wall of the lens house 2.

Here, by connecting a hose (not shown) extended from a smoke suction device to the outlet 6, smoke generated during the surgery is efficiently sucked in from the inlet 5.

In this embodiment, the first discharge port 10 and the second suction port 11 are connected via the O-ring 7, so that airtightness is sufficiently maintained.

However, if the first outlet 10 and the second suction port 11 are fitted together to maintain sufficient airtightness, or if some leakage is acceptable, the O-ring 7 is omitted.

FIG. 2 shows a perspective view of the probe 8.

Here, a first suction port 5 provided on the inner wall side of the distal end of the probe 8 and a cylindrical first discharge port 1 provided on the side of the proximal end.
0 are in communication with each other via the air pipe 12, as described above.

Further, the number of first suction ports 5 provided at the tip portion is not limited to one, and a plurality of first suction ports 5 may be provided.

Furthermore, the connection between the probe 8 and the lens house 2 is not limited to tightening with the lock nut 13 as described above.

That is, a method may be used in which the distal end portion of the lens house 2 is fitted into the proximal end portion of the female-shaped probe 8, or a chuck means may be used.

In short, it is important that the probe 8 can be replaced quickly.

Next, another embodiment of the probe 8 will be described based on the longitudinal sectional view shown in FIG.

Here, an air pipe 12 is joined along the side wall of the probe 8.

The upper end of the air supply pipe 12 passes through the proximal end of the probe 8 and forms the first outlet 10, and the lower end passes through the tip of the probe 8 and forms the first suction port 5.

Further, in the vicinity of the first discharge port 10, an O-ring 7 made of an elastic body is attached as described above.

It goes without saying that the probe 8 is connected to the lens house 5 in the same manner as in the previous embodiment.
