Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an endoscope holder.

[Conventional technology]

Regarding endoscope holders, Japanese Patent Laid-Open No. 131256/1982 and Japanese Utility Model Publication No. 52-50291.

As shown in Japanese Utility Model Application Publication No. 53-39834, a structure using a plurality of joints has conventionally been used.

In addition to constructing a flexible holder body by connecting multiple arms using multiple joints, these endoscope holders include
Inside one end of the holder body? J! An integrated structure with an endoscope holder for fixing the mirror is used, and the other end of the holder body is fixed to support the entire endoscope holder and to appropriately fix the joints. This allows the endoscope to be fixed in the desired position.

[Problem that the invention seeks to solve]

By the way, the endoscope holder is designed to protect the endoscope and the operator who operates the endoscope from the viewpoint of preventing infection, since the endoscope is used to observe and treat the inside of the body cavity. Nearby, i.e. within? j The mirror holder side must be kept in a sterile condition. For this reason, sterilization is considered essential for use.

However, within the conventional? J! ! The holder is integrated from the endoscope holding part to the fixing part. For this reason, sterilization must be done either by sterilizing the entire endoscope holder, which is extremely difficult due to the sterilization equipment, or by using inadequate disinfection methods such as wiping with Hibitene alcohol. I have no problems.

The present invention has been made in view of these problems, and an object of the present invention is to enable easy and sufficient sterilization of the endoscope holder side.

[Means and effects for solving the problem] In this endoscope holder, sterilization is facilitated by providing a connection part 28 in the middle of the holder main body 1 for separating the endoscope holder side A. Only the essential endoscope holder side A is removed from the holder main body 1 and thoroughly sterilized.

[Embodiment] FIGS. 1 to 7 show an embodiment of the present invention. Second
The figure shows the entire endoscope holder, where 1 is the holder main body and 2 is a power supply unit. The power supply unit 2 has a light source device 4 inside the cabinet 3. Drain pump5. Power supply device for high frequency treatment 6. Furthermore, it houses equipment necessary for endoscopic observation and treatment tools, such as a power supply device for an ultrasonic scalpel (not shown).

On the other hand, the holder main body 1 has a plurality of joints 7a, for example, four joints 7a.
, 7b, 7c, and 7d to connect the five arms 8 to each other, and an endoscope holder 10 is provided on the arm 8 on the distal end side. Note that among the arms 8 constituting the holder main body 1, the two on the distal end side have short overall lengths.

And each joint 7a, 7b of this holder main body 1.

The structures of 7c and 7d are shown in FIGS. 3 and 4, and the structure around the endoscope holder 10 is shown in FIGS. 5 and 6.

Now, to explain the joints 7a, 7b, 7C, and 7d, each arm 8 has a pipe-shaped arm cover 8.
A structure is used in which a connecting shaft 8b is inserted into the inside of the connecting shaft 8b, and each end of the connecting shaft 8b is connected by a joint having a degree of freedom in one direction, for example. Specifically, 11 is a drum-shaped joint ball integrally provided at one end of the two connecting shafts 8b, 8b adjacent to each other, and 12 is the joint ball integrally provided at the other adjacent end of the two connecting shafts 8b, 8b. A receiver having a shape corresponding to the outer shape of the ball 11 is a joint ball receiver 12 having a space. The space in the joint ball receiver 12 is formed to have a thickness slightly smaller than the thickness of the joint ball 11. And 1. In the center of both sides of the joint ball receiver 12, a parallel gap is formed with a dimension smaller than the thickness of the joint ball 11, and in communication with the gap, the receiver extends from the back of the space to the end side of the connecting shaft 8. A wedge-shaped notch 13 is formed across the length, forming a tightening force relieving portion. Further, at each end of the gap between the joint ball receivers 12, coil supporting wall portions 14.14 are provided to protrude outward in parallel, respectively, and these coil supporting wall portions 14.14.
Two pairs of excitation coils 15 are installed on the inner surface of the coil 14, facing each other and spaced apart from each other. The joint ball 11 is fitted into the space of the joint ball receiver 12, thereby forming each joint 7a, 7b, 7G, and 7d. That is, these joints 7a, 7b, 7c.

In the normal state, the movement of the joint 11 is restrained by receiving the tightening force of the joint ball receiver 12, that is, the joint 1
1 is fixed (joint: fixed) and the excitation coils 15... are excited, so that the excitation coils 15.1 facing each other are
The joint 11 can be freely moved in one direction (joint: free) by relaxing the tightening force from the repulsive force of 5. Note that 16 is a joint cover that covers the periphery of the joint and is integrally connected to the arm covers 8a, 8a. Of course, this joint cover 16 is composed of two pieces that can rotate on the center of the joint. And each of these joints 7a, 7b, 7c
, 7d, the initial tightening force by the joint ball socket 12 is set to be small at the joint 7a on the distal end side and to increase toward the joint 7d on the rear end side, as shown in FIG. Of course, this tightening force is determined by the joint ball 11. Joint ball receiver 12. It is determined from changes in the size of the notch 13 and the like. In addition, in FIG. 3, 17 is a power cord for coil excitation, which is inserted between the arm cover 8a and the connecting shaft 8b.

Next, the area around the endoscope holding part 10 will be explained. As shown in FIG. The endoscope attachment is configured by providing a section 20. However,
Is this endoscope installed inside part 20? ! Im, for example, by locking and fixing near the light guide connecting portion 22 of the rigid scope 21, the rigid scope 21 can be held (fixed). Note that although not shown in the drawings, the fixing is performed by fixing means such as screws or clicks.

Further, a holding grip 23 is provided on the outer periphery of the arm cover 8a on the distal end side, and excitation coils 15 for the joints 7a to 7d are provided on the held surface of the holding grip 23.
A switch 24 that turns 0N10FF and a pressure sensor 25 that controls the movability of the joints 7a to 7d are arranged in parallel, and the fixing force of the joints 7a to 7b is controlled from the gripping condition of the holding grip 22 to achieve a rigidity of 11t21. It is designed so that it can be moved freely to the desired position and fixed. Here, the control of the joints 7a to 7d by the pressure sensor 25 will be explained. For this control, a control circuit as shown in FIG. 6 is used.

That is, in addition to connecting the switch 24 and the pressure-sensitive sensor 25 in series, the control circuit also includes the pressure-sensitive sensor 25 connected to the first amplifier 26. A circuit is used in which the second amplifier 27 is connected to the excitation coil 15 of each joint 78-7d via the power cord 17. In this control circuit, as the holding grip 23, switch 24, and pressure sensor 25 are gripped more firmly, the negative magnetic force of the excitation coils 15 can be increased. Here, each joint 7a
~7d, as mentioned above, the desired tightening force is set to be smaller as it approaches the distal joint, so the setting of the desired tightening force and the input from the pressure sensor 25 are In combination with the control of the repulsive force, the joints 78 to 7d are fixed or freed according to the input from the pressure sensor 25. In other words, by gripping normally, the restraint of the distal joint 7a, which is most frequently used, is released, by gripping it slightly more strongly, the restraint of the joint 7b, which is the next most frequently used joint, is also released, and by gripping even harder, the restraint of joint 7C is released. The joint 7d is also released, and by gripping it even harder, the entire restraint including the joint 7d can be released. This is a control in which the joint 7a, which is closer to the user's hand and has a high frequency, moves first, and the joint 7d, which is far away and has a low frequency, does not move much.

The arm 8 on the pseudo-end side of the holder main body 1 is fixed to the cabinet 3 in an upright position, and constitutes an inner pA mirror holder with the power supply unit 2 as a pedestal, that is, a fixed part. . Of course, the power cord 17 is connected to the power supply unit l-2.

A connecting portion 28 is provided in the middle of the holder main body 1 of the endoscope holder configured as described above, for example, on the arm 8 between the joint 7C and the joint 7d. Its structure is shown in FIG.

Here, to explain the structure of the connecting portion 28, a portion on the arm 8 close to the joint 7C is separated into an endoscope holding portion side A and the other portion on the fixing portion side B. Incidentally, upon separation, the end of the connecting shaft 8a is fixed, for example, at a point retracted from the separation end of the arm cover 8a. Then, at the end of the separated endoscope holding part side A, for example, a connector 29aIF! for a treatment instrument power supply (for high frequency current supply)! : In addition to being connected to the connector case 29 (corresponding to the connector of this invention) at the rear, the front side of this connector case 29 is
A male connector 32 is provided with a large number of contacts 30 on the outer periphery of the distal end and screws 31 on the other outer periphery, and constitutes the endoscope holding part side A.

Note that the contacts 30... are connected through two connector cases.

Excitation coils 15 for joints 7a to 7C, switches 24
, is connected to the pressure sensor 25, and at the same time is connected to the connector 29a, so that the power necessary for joint control can be sent through the contacts 3o, etc., and the high frequency of the rigid endoscope 21 can be transmitted. This allows it to deliver the electrical current necessary for the treatment being used. In addition, the entire endoscope holder side A separated in this way has a waterproof structure that can withstand sterilization, and the parts necessary for sterilization are attached to B11.
1 to ensure sufficient sterilization.

On the other hand, the arm end on the separated fixed part B side is fitted onto the outside thereof. Then, the contact point 3o is attached to the inner circumference of the arm end.
・A large number of contacts 34 are provided to connect with the arm connection ring 33 and the male connector 32 to removably connect the endoscope holding part side A and the fixed part side B. It constitutes a connecting portion 28 that can be used. In other words, while connecting the separated arms 8, the contacts 30..., 34...
・It has a structure that allows communication between comrades. In addition, the contact points 34... are connected to the excitation coil 15. of the H7d. The power supply unit 2゜ is further connected with a cord 35 connected to equipment such as a high-frequency treatment power supply 6, and joint control is performed with the connection between the endoscope holding part side A and the fixed part side B. It is possible to supply the power necessary for the operation of the rigid endoscope 21, send and receive signals, and supply the power necessary for the treatment of the rigid endoscope 21.

On the other hand, 36 is a belt. This belt 36 is attached to the arm 8
. . . at an appropriate position above, for example near the end of the arm after the joint 7a, the connector case 29. They are provided in a ring shape at a plurality of locations, such as on the arm 8 in front of the joint 7d. And these 38, for example, a light guide,
By inserting the power cord etc. for high frequency treatment power supply,
Prevents tubes and cords from coming apart.

In other words, inside? J! This prevents operations from becoming complicated due to tubes and cords.

Therefore, when holding the rigid scope 21 using the endoscope holder configured in this manner, the rigid scope 21 is held by the patient 4.
0, hold the holding grip 23 normally. As a result, when the switch 24 is turned on, the degree of gripping is sensed by the pressure sensor 25, and the joints 7a to 7d are controlled through the excitation coils 15.

Here, since it is normally grasped, the joint on the hand side,
The brake (restraint) on the joint 7a is released, and only the hand can move. In addition, the irrigation port 21a of the rigid endoscope 21.

The tube connected to 21a and the light guide connected to the light guide connection part 22 are attached to the belt 36.36 in advance.
Through the light source device 4. It is connected to the drainage pump 5. Of course, when performing treatment using high frequency, the power supply cord 42 is connected in advance between the high frequency power input terminal (not shown) of the rigid endoscope 210 and the connector 29a of the connector case 29.

Then, while gripping the endoscope, attach the part 2o to the rigid endoscope 2.
If the endoscope is placed and fixed near the light guide connecting portion 22 of No. 1 and the holding grip 23 is released, the endoscope can be fixed at the intended position. Here, as the fixing operation, the operation of grasping and moving the holding grip 23 and the operation of releasing the fixation of the joint 7a are performed at the same time, so that the endoscope can be fixed with good operability. Moreover, since only the joint 7a on the proximal side is unlocked, the joint 7C on the power supply unit 2 side.

7d does not move much, and when fixing the endoscope, the endoscope mounting part 20 does not move unintentionally, and the endoscope can be fixed with good operability even with this cap. It becomes possible. Note that the fixed endoscope 21 cannot be fixed (tightened) at each joint 78 to 7d even if the switch 24° pressure sensor 25 is turned on unless the operator grips the holding grip 23 sufficiently. ) The strength does not decrease suddenly, and the rigid endoscope 21 in the inserted state does not fall or suddenly move.

Then, through the rigid scope 21 fixed in this way,
Among these? ! The endoscope holder must be kept in a sterile state near the operator, but in the past, it was difficult to sterilize the entire endoscope holder.

It has been pointed out that inadequate disinfection methods are being enforced.

However, according to the present invention, the connecting portion 28 is provided so that the endoscope holding portion side A can be freely separated.

This means that when performing sterilization, the endoscope holder side A can be separated from the holder main body 1, and the endoscope can be preserved and sterilized easily.

As a result, in addition to preventing infection, the operator can operate the rigid scope 21 and endoscope holder without touching the contaminated area, making observations and treatments possible without having to think about the contaminated area. As a result, the safety of observation and treatment operations can be improved accordingly. Moreover, is the connector case 29 equipped with the connector 298 inside? By providing lA1ff on the holding section side A, gas sterilization is also possible.

In the above-described embodiment, the connector case is provided with a connector for supplying high-frequency current, but the connector case is not limited to this, and may include a connector for connecting a light guide and a connector for irrigation water.

In addition, lit! for treatment tools! A connector for connecting the cord may be provided, and all such connectors are not limited to being provided in the connector case, and one or more of these connectors may be provided.

Further, in the above-described embodiment, the joints are fixed or released on the hand side, but each joint may be operated using a foot pedal operated with the foot.

〔Effect of the invention〕

As explained above, according to the present invention, the endoscope holding portion side can be easily and sufficiently sterilized.

As a result, infection can be easily prevented.

Moreover, since we operate a fully sterilized endoscope holder,
This allows the user to concentrate on observation and treatment, which has the advantage of improving the safety associated with observation and treatment work.
