Description

  The present invention relates to a surgical leg support (surgical kneerest) that supports a surgeon's knee or shin to reduce surgeon fatigue during surgery.

  In recent years, laparoscopic surgery has been actively performed. This operation is performed by making a plurality of small holes on the surface of the patient's abdomen and inserting a dedicated endoscope into the body through the holes. Compared with conventional open surgery, laparoscopic surgery has advantages such as (1) less pain after surgery, less noticeable surgery, (2) less bleeding, and (3) early discharge after surgery. There are high needs from patients. Because of these advantages, laparoscopic surgery is rapidly spreading. However, since the degree of difficulty of the operation is high, the operation time is prolonged to 2 to 5 hours, and the fatigue and burden on the surgeon are increased.

  FIG. 2 of Non-Patent Document 1 describes an instrument that supports a surgeon's chest to reduce the surgeon's fatigue.

  Further, FIG. 1 of Patent Document 1 describes an instrument that supports the buttocks and shins of an operator in order to reduce fatigue of an operator who is not developed for a surgeon. Yes.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention can be implemented in many different forms, and is not limited only to the examples described in the following embodiments.

<First Embodiment>
FIG. 1 is a diagram showing a first embodiment of the present invention. In this embodiment, the base part 1 set | placed on a floor is comprised by the plane plate shape. A bar-shaped support 2 is attached to the upper part of the base part 1, and a bar-shaped leg support 6 is attached to the support 2 perpendicularly to the upper part of the support 2.

  During the operation, the surgeon presses the upper part of the knee or shin (hereinafter, these parts are collectively referred to as “legs”) against the leg support during the operation from the back side in FIG. She leans over and performs surgery with a comfortable posture.

  A support column support 3 is attached to the upper part of the base unit 1 to support the support column 2. In the present embodiment, the support column support 3 is attached to reinforce the support column 2, but the support column support unit 3 is not essential.

  The leg support portion 6 is composed of a rod-like leg support rod 601 and a leg contact portion 602 which is attached around the leg support rod 601 and made of a soft material such as sponge or silicon rubber.

  In the present embodiment, the leg support 6 is formed in a columnar shape. However, if the leg support 6 is formed into a flat plate shape or a shape that fits the shape of a human knee, the surgeon can perform a more comfortable operation. This is desirable because it can.

  It is necessary to adjust the height of the leg support 6 according to the physique of the surgeon. Also, there are differences between individuals depending on which part of the leg hits the leg support 6, and some people feel comfortable when the kneecap hits. Some people feel more comfortable when pressed against the upper part, and it is necessary to adjust the height of the leg support 6 in order to meet the user's preference.

  Therefore, the support 2 is provided with an adjusting unit 4 that adjusts the height of the leg support 6. Specifically, the second support column 202 is inserted into the first support column 201, and the hole of the second support column 202 (not shown) and the hole 401 of the first support column 201 are fixed with pins or screws or the like. .

  When the height of the leg support 6 is desired to be adjusted, the pin or screw is removed, and the hole of the second support column 202 where the leg support 6 is at an appropriate height is fixed with the pin or screw. Reference numeral 604 denotes a shaft portion of the leg support portion, which is provided with an insertion hole 603 for inserting the second support column 202, and rotatably supports the leg support portion 6.

  The material of each part of the surgeon's leg support may be metal, plastic, or other material, and is not particularly limited. However, the use of plastic has the advantage that it can be made inexpensively and is lightweight.

  The pedestal 1 stabilizes the entire leg support for a surgeon by placing both feet and applying weight, and the region on which both feet are placed (the center or almost the central region of the pedestal) is referred to herein as the sole of the foot. In addition, as much space as possible is provided so that the sole and its surroundings can move freely, and mats such as low-resilience mats and health equipment such as green bamboo can be installed according to user's preference according to preference Yes.

  FIG. 2 is a diagram schematically illustrating a state in which the surgeon 8 is using the leg support when performing surgery on the patient 9.

  The surgeon 8 operates the surgical tool 10 on the patient 9 lying on the operating table 11 and performs an operation. At this time, the upper part of the shin is pressed against the leg support part 6 to lean against it. Surgery can be performed with a proper posture.

  For this reason, even if a long-time operation is performed, fatigue can be reduced and concentration can be maintained.

FIG. 3 is a view of the movement of the leg support 6 according to this embodiment as viewed from above.
In the present embodiment, the leg support portion 6 is supported so as to be rotatable about the support column 2, and the leg support portion 6 can rotate in either a clockwise direction 1201 or a counterclockwise direction 1202 as viewed from above. It has become.

  With this structure, when the surgeon twists his body and receives a surgical instrument from the nurse, the leg contact portion 602 can be moved in the front-rear direction as viewed from the surgeon who is the user.

  During the operation, the patient's condition may change suddenly, and the surgeon may have to operate a distant site. Even in such a case, the leg support 6 rotates and the leg contact 601 moves back and forth. Since it can move in the direction, it can be quickly treated and handled, and it does not limit the movement of the surgeon's knee, so it can respond smoothly and quickly.

  FIG. 4 is a side view of the surgeon's leg support of this embodiment. In the present embodiment, the attachment angle θ of the support column 2 with respect to the base portion 1 is about 80 degrees.

  In the support device described in Patent Document 1, the support column is vertically attached and the attachment angle is 90 degrees. However, when the surgeon uses such a support device and presses the knee and shin, Because the posture is unstable, it is possible to fall forward by pinching, and there is a risk of damaging an inappropriate part of the patient.

  Therefore, it is appropriate that the mounting angle of the support column 2 is 80 degrees or less. In addition, if the attachment angle of the support column 2 is too small, the entire leg support for the surgeon is increased in size. Therefore, the attachment angle of the support column 2 is desirably 45 degrees or more.

<Second Embodiment>
FIG. 8 is a diagram illustrating a state in which the leg support portion 6 according to the second embodiment of the present invention is viewed from above, and the description of the same parts as those of the first embodiment is omitted.

  In the present embodiment, a leg support plate is fixedly attached to the shaft portion 604, a spring 605 that is an elastic body is attached to the leg support plate 606, and a leg contact portion 602 is attached to the other end of the spring 605.

  At the time of use, the leg 13 of the surgeon who is the user is in contact with the leg contact portion 602, but the leg contact portion 602 can move back and forth (in the direction of the arrow 1203) as seen from the surgeon by the expansion and contraction of the spring 605. It has a structure.

  With this structure, even when the surgeon is forced to perform treatment by projecting one knee forward due to a sudden change in the patient's condition during surgery, the surgeon can project one knee and take appropriate measures.

  Comparing the first embodiment with the second embodiment, the first embodiment can (1) be able to extend the distance that the knee can be projected, and (2) the distance that can project one knee. It can be controlled by adjusting the force applied to one knee (it can prevent one knee from protruding too far by stroking the other knee), (3) Simple structure and creation There are advantages such as being easy.

  In this embodiment, the leg contact portion 602 is supported by an elastic body so that the leg contact portion can be moved in the front-rear direction. However, by using an elastic body as a part of the support 2, the leg is bent by the elastic body. It is good also as a structure which the contact part 602 can move to the front-back direction.

  FIG. 5 is a diagram showing the appearance of the prototype of the present invention (hereinafter referred to as “the prototype”), FIG. 6 is a diagram showing a state in which the leg support portion 6 of the prototype is rotated, and FIG. It is a figure which shows the upper body using this prototype.

  In FIG. 5 to FIG. 7, description of the same parts as those in the first embodiment is omitted. This prototype differs from the first embodiment in that the base 1 is mainly configured by arranging and connecting four pipes on a rectangular side instead of a flat plate.

  The surgeon performs the operation by pressing the knee or shin against the leg support 6 as shown in FIG.

  This prototype is mainly created by connecting plastic pipes for easy production. However, in actual products, the area where the surgeon's knees and shins come in contact is flat, or a soft material such as sponge is used. It is desirable to provide a comfortable contact feeling by arranging the components.

  As shown in FIG. 6, the leg support 6 is structured to rotate about the support column 2 so that the surgeon can smoothly operate the knee without restricting torsion of the left and right upper body. Yes.

  Depositing knees alternately reduces the anti-gravity burden on the ankle that is necessary to maintain the standing position, and further reduces the burden on the waist because the hip joint is released from the static maintenance of the extended position.

  Further, when blood is congested in the surgeon's knee, the knee can be actively moved to reduce fatigue.

  As shown in Fig. 7, pipes are placed at the parts where the soles of the feet come into contact, but this part can be shaped like a green bamboo tread or a low-resilience mat can be used for comfort and wide use of the soles. It becomes possible to cope with the preference of the person.

  In addition, as a response to the user's preference, it is possible to additionally set a buttocks support device, and it is expected to be used as a lower body support tool including not only the lower limbs but also the buttocks.

  Compared to the support described in Patent Document 1, the prototype is small and lightweight, does not hinder the movement of surgical staff during surgery, and can be easily carried when not in use, Even if the support body is contaminated with blood or blood, there is an advantage that it can be easily wiped and cleaned.

  Although the above-described embodiment has been described as a leg support device for a surgeon, it is possible to provide a comfortable working environment not only for a surgeon but also in all fields.

  The present invention can provide a comfortable working environment in all fields with a simple structure.
