Description

  The present invention relates to a standing position holding device. More specifically, the present invention relates to an instrument suitable for use in holding a standing position of an operator when, for example, a patient lies on an operating table and the surgeon performs an operation in the standing position.

  For example, in a microscope operation such as neurosurgery, an operator uses a dedicated foot pedal to adjust the focus and zoom of the microscope. In head surgery that the surgeon can perform in the sitting position, it is possible to perform the surgery while sitting on a dedicated chair that is relatively versatile, and the operator's position is stably maintained There is little fatigue in the lower limbs. On the other hand, in spinal surgery performed by the surgeon in a standing position due to restrictions on the position of the surgical site, the posture becomes unstable due to a single-leg standing posture with the pivot foot when operating the above-described dedicated foot pedal. When the body posture becomes unstable, muscle strength is required for stabilization, and a long-lasting operation places a heavy burden on the lower limbs and causes fatigue. Furthermore, misalignment between the eyepiece of the microscope and the surgeon's eyes caused by the unstable body posture also causes fatigue. In addition, since both arms, which occupy approximately 16% of the body weight, are in a free state, not only fatigue is amplified, but there is also concern about adverse effects on the quality of surgery. Specifically, for example, spinal surgery, which is one of the typical operations performed in a standing position, is a spinal cord of only about 10 mm, and takes 5 to 6 hours using a surgical microscope. Long and delicate work is required. In such a case, in particular, as in the case of the sitting position, it is necessary to ensure a comfortable operability of the surgical instrument by the operator and to maintain the stable posture of the operator, as in the case of the sitting position. It is done.

  For example, as shown in FIG. 13, when the operator 101 holds the buttocks of the operator 101 with a saddle-shaped body holding seat 102 and takes the forward leaning posture as a conventional auxiliary instrument that considers maintaining the posture of the operator. There is one that supports and holds the chest with a breastplate 103 (Patent Document 1). In the auxiliary instrument shown in FIG. 13, the body holding seat 102 is installed by being attached to the operating table 104 via a slide mechanism 105 and a turning mechanism 106 fixed to the operating table 104 and an arm 107 that rotates in the horizontal direction. Is done. In FIG. 13, reference numeral 108 represents a patient.

JP 2007-29504 A

  However, in the auxiliary instrument of Patent Document 1, when the operator 101 is not in a forward leaning posture and does not use the breast pad 103, the posture is unstable because the operator 101 is riding on the bicycle. On the other hand, when the breast pad 103 is used while taking a forward leaning posture, there is pressure on the chest and fatigue is induced. For this reason, it is not possible to ensure a comfortable operability of the foot pedal for adjusting the focus and zoom of the microscope, for example, by the operator 101, and to maintain the posture of the operator 101 stably while reducing fatigue. It cannot be said that comfort and functionality are high for the surgeon.

  In addition, the posture required for, for example, a surgical operation under a microscope in an upright position is an upright or slightly forward tilted posture, and the degree of freedom of the upper body must be ensured while stabilizing the posture. However, in the auxiliary device of Patent Document 1, the chest is pressed against the breast pad 103, and thus the degree of freedom of the upper body cannot be ensured. For this reason, it can be used for any of various types of operations performed in a standing position, and is not highly versatile.

  Moreover, in the auxiliary instrument of patent document 1, since the body holding seat 102 is installed on the operating table or the operating room ceiling, a dedicated operating table is newly purchased or directly applied to the operating room.

Therefore, it is possible to realize better and better posture change and posture maintenance of the operator.

  Since the standing position holding device 1 of the present invention configured as described above can function as a support device for the surgeon 2 independently by itself, it affects existing facilities and facilities. And is very versatile and easy to install. Moreover, since it can be used in combination with a device related to the operation of a surgical device such as the foot pedal 7a of the microscope 7 of this embodiment, for example, it is very versatile and easy to introduce.

  Moreover, according to the standing position holding device 1 of the present invention configured as described above, the posture is supported by supporting the iliac bone of the operator 2 in the standing position from the front and right and left sides with the iliac support part 30. Since it stabilizes, it is possible not to compress the chest and abdomen (built-in) of the operator 2 and to avoid using the muscle strength of the lower limbs more than necessary. Can reduce fatigue. Furthermore, even when the surgeon 2 stands on one foot, for example, to operate the foot pedal used to operate the surgical equipment, the posture can be stabilized while maintaining the freedom of the upper limbs, and free surgical operations can be performed. It is possible to secure a stable standing position by securing the body position in the front-rear direction and the left-right direction.

  In addition, since the anteversion gradient is slightly added to the upper surface of step 42 (most preferably about 5 degrees), the operator 2 leaves the body to the iliac support portion 30 in a natural state, and is in a slightly anteversion posture. It is possible to maintain a comfortable posture naturally without using extra muscular strength and to reduce the burden on the heel. For this reason, the fatigue of the operator 2 can be reduced.

  In addition, since the upper body, particularly the upper limb, is stabilized by supporting both arms of the operator 2 occupying about 16% of the body weight from below with the armrest 20, the chest of the operator 2 is particularly compressed to stabilize the upper body. It is possible to prevent the surgeon 2 from using the muscle strength of the shoulders and arms more than necessary, and therefore the fatigue of the operator 2 can be reduced.

  And since it can reduce the fatigue of the surgeon 2 and stabilize the posture as described above, the surgeon 2 can perform delicate work and can perform delicate work for a long time, and has high quality. It becomes possible to improve the quality of surgery by realizing the procedure.

  Further, since the height adjusting mechanism 50 and the width adjusting mechanism 60 are provided, the armrest 20 and the iliac support portion 30 are fixed at desired positions according to the physique of the operator 2 and the posture at the time of the operation. For this reason, it is possible to realize better change of the posture of the operator and maintenance of the posture.

  Further, the portion where the part of the body of the operator 2 abuts is formed of a material having an appropriate elasticity for dispersing the body pressure (specifically, for example, an elastomer gel). It is possible to improve and reduce the surgeon's fatigue.

  In addition, although the above-mentioned form is an example of the suitable form of this invention, it is not limited to this, A various deformation | transformation implementation is possible in the range which does not deviate from the summary of this invention.
