Abstract

PROBLEM TO BE SOLVED: To provide a medical instrument holding device of a universal joint type which uses a ball joint at a joint portion, while resolving the problem with such a holding device that, when used repeatedly over a long period, the spherical surface of a ball wears out because of point contact between the spherical surface of the ball and the end face of an arm, causing the result that the functions of the universal joint are lost and a medical instrument cannot be selectively set in a predetermined position and attitude. SOLUTION: A medical instrument holding element C is connected to the end of a supporting rod 2 via a stacked connector A and pairs of upper and lower links B, B, B' and B' in such a manner as to be freely rotatable and oscillatable relatively to the supporting rod 2, the stacked connector A being freely rotationally attached to the end rod portion 2a of the supporting rod 2, and the pairs of upper and lower links B, B, B' and B' extending forward from the stacked connector A and freely oscillationally disposed in right and left positions. Rotation of the stacked connector, oscillation of the right and left pairs of upper and lower links B, B, B' and B' and oscillation of the medical instrument holding element C are fixed at a time by operation of a handle D, so that the medical instrument E held against the medical instrument holding element C can be fixed and maintained in the desired selected position and attitude.

[0001]

TECHNICAL FIELD The present invention relates to a held endoscope,
The present invention relates to a medical device holding device capable of fixing and holding a medical device such as an exclusion hook at a desired position and posture.

[0002]

2. Description of the Related Art Conventionally, when a surgeon performs a surgical operation on a patient's abdomen, for example, by performing a surgical operation on a patient's abdomen, the assistant is required to secure a desired surgical field of view and not to obstruct the operation, for example, by using a retraction hook ( The retractor was used to hold the grip and tow to open the wound, and to maintain the retracted state during the operation, it was held in its position and posture for a long time, but the assistant was tired. As a result, it becomes difficult to hold the initial traction, and as a result, the initial position and posture cannot be maintained, the required retracted state cannot be maintained, and it becomes difficult to perform the operation promptly and smoothly, and an unexpected obstacle is caused. There was anxiety that could occur. In order to eliminate such inconveniences, a retractor holding device has been developed and used to hold the retractor entering the position and posture by mechanical force instead of the assistant after the assistant opens the wound with the retractor. Was. Among them, there is a retractable three-joint retractor called "Octopus universal retractor". In this holding device, the joint part connecting the main body support rod and the second arm and the joint part connecting the arms are each configured by a universal joint made of a ball.

[0003]

However, if the conventional three-joint holding device is used for a long time, the spherical portion of the ball that comes into contact with the end surface of the arm against which the ball is pressed by point contact. As a result, the operation of the universal joint by the initially smooth ball was hindered, and as a result, the retractor could not be held at the desired position and posture. Therefore, a medical device that solves the conventional inconvenience and can fix and hold a retractor, an endoscope, and other desired medical devices at a desired position and posture without being worn even when used for a long period of time. The development of a holding device is desired.

The medical device holder C attached to the distal end portion of the medical device holding device 1 of the present invention is rotatable with respect to the support rod 2 and is mounted to be swingable in the vertical direction.

One example of the medical device holder C is shown in FIG.
As is clear from the exploded view shown in FIG. 1, a pair of upper and lower link rods B, B, B ', B' are rotatably mounted on the left and right sides via the left and right connecting plates 13, 13 '. A main body C1 comprising a substantially rectangular parallelepiped block and a holding member C3 opposed to the tip of the main body C1 and provided with a medical device in front of the main body C1 with or without an adapter F, and operating the holding member. And a screw device C4 that performs
Between the front end of the main body C1 and the holding member C3, a holding portion C2 capable of holding a medical device is formed. More specifically, the tip of the main body C1 is a cylindrical handle e of the medical device E.
Is formed on an arc-shaped front end edge C12 suitable for holding or abutting the peripheral side surface of the cylindrical adapter F directly or on the side surface of the adapter F. On the other hand, the tip of the holding member C3 is the handle e of the medical device E.
Is formed on a holding member C31 formed in a holding portion C31 which is curved in an arc shape and is suitable for abutting directly or via an adapter F. It is accommodated and inserted in the letter-shaped insertion groove C13,
As will be described later in detail, the rear end portion is provided with the holding main body C1.
And was connected to a screw device C4 for operation so as to be freely pressed against the rear end face. The screw device C4 includes a cubic rear block piece C43 having an operation knob C41 and a screw hole C431 for screwing the screw C41 through the front and rear surfaces, and the knob C located in front of the rear block piece C43.
And a front block piece c44 of a cubic shape having a screw hole C441 for screwing the 41 screw rod C42 through the front and rear surfaces. C434 indicates a screw that is inserted into and engaged with the annular groove C421 formed at the base of the screw C42 of the knob C41. Further, on one side of the front and rear block pieces C43 and C44, receiving grooves C432 and C442 each having a U-shaped cross section for receiving the rear end side of the holding member C3 are formed and stored therein. A pin hole 17 drilled vertically in the rear part of the holding member C3 and the pin hole 1 in a corner of the rear block piece C43.
The connecting pin 19 is inserted into the pin hole 18 formed in alignment with the nut 7, and nuts 20, 20 are screwed into the threaded portions 19 a, 19 a at the upper and lower ends of the pin 19.
Is rotatable by 90 degrees around the pin 19,
A guide pin C43 protrudes from the rear surface of the front block piece C44, and the guide pin C443 is inserted into a guide hole C433 provided on the front surface of the rear block piece C43.
1 is twisted in one direction or the other direction, whereby the front block piece c44 is advanced, and can be freely pressed against the rear surface of the block body C1, and accordingly, the holding portion C of the holding member C3
The medical device E is sandwiched between the front end 31 of the block body C1 and the front end C12 of the block body C1, or the operation thereof is released.

[0010] The medical device holding body C thus configured is
It works as follows. First, in order to attach the medical device E to this, the medical device holder C is tilted upward or downward, and the operation screw device C4 is connected to the pair of right and left upper and lower link rods B, B, B ', B'. FIG. 8
