Description
Technical field
The utility model relates to medical auxiliary instruments, and in particular to a kind of for surgical operation or the sit-astride of experimental implementation
It stands chair.
Background technique
Surgeon generally completes to perform the operation with stance, it is prolonged stand may cause lumbar muscle strain, knee joint,
The illnesss such as hip arthralgia, varix of lower limb.But doctor is still seldom sitting on chair and performs the operation.The factor for needing to consider is answered
Have: sitting posture will increase doctor above the waist at a distance from operating table, and be not easy to doctor's transformation angle and adjustment posture in art；Operation
Platform surrounding instruments equipment is more, and the volume of conventional chair is excessive；Operating room sterilizes the hidden danger for requiring seat not bring pathogen transmission；One
The switch setting of a little instruments is controlled in a manner of trampling on ground.
The universal ball-and-socket joint rotation of atmospheric pressure pole lifting technology, gravity brake wheel technology, Self-resetting on the market now with it is automatic
Resetting technique all comparative maturities are based on these existing technical components, can integrate out current product primary.But how
In conjunction with before consider element, the station chair for designing the various required functions of fusion doctor does not show city yet.
Summary of the invention
In conjunction with the investigation for surgeon's demand, new design concept is incorporated, the utility model proposes a kind of use
It is operated simultaneously in the sit-astride station chair of surgical operation or experimental implementation suitable for some operations that stand for not needing to move position
When hand do not rise not come out, for example perform an operation or test.
The sit-astride station chair for surgical operation or experimental implementation of the utility model includes: sit-astride cushion, the first rank
Relay part, lifting atmospheric pressure pole, fixed device, height adjustment pedal, the second interface components, the universal ball-and-socket joint of Self-resetting, triangle bottom
Seat and gravity brake wheel；Wherein, sit-astride cushion is axisymmetric structure, including the front and back two parts being connected as one, front
Divide narrow, rear portion split-phase part of the force greatly main for preceding area；The lower surface of sit-astride cushion passes through the first connection
Component is connected to the top of lifting atmospheric pressure pole；The center of fixed device has fixed hole, and the side of fixed device has limit
Through-hole；The bottom end for going up and down atmospheric pressure pole passes through fixed hole and the fixation of fixed device；Height adjustment pedal is lever construction, lever
One end the regulation button of lifting atmospheric pressure pole bottom is connected to by the limiting through hole of fixed device, foot is arranged in the other end of lever
Pedal；The lower surface of fixed device is fixed on the upper surface of the second interface components；The lower surface of second interface components connects runback
The universal ball-and-socket joint in position；The universal ball-and-socket joint of Self-resetting is mounted on the upper surface of triangle base；Triangle base is axisymmetric structure, packet
Centre post, two tail support bars and mounting disc are included, tail support is respectively set in the two sides of the rear end of centre post
Mounting disc, Self-resetting multi-directional ball is arranged in the upper surface of centre post so that the top of three support rods constitutes triangle in bar
The lower surface of nest section is fixed on the upper surface of mounting disc, and the slant range of sit-astride cushion is located at the inside of triangle；In triangle
Gravity brake wheel is respectively set in the lower surface on the top of three support rods of pedestal.
Two legs of user are located at left and right sides of the preceding part of sit-astride cushion, and the perineum contact of user rides on
The rear part of formula cushion, to undertake a part of weight, while the both feet of user do not leave ground simultaneously, and one of user
Foot tramples the foot pedal of height adjustment pedal, to press regulation button, adjusts the height of lifting atmospheric pressure pole, sit-astride cushion is held
The gravity of part user is carried on a shoulder pole, gravity brake wheel is locked, and the position at sit-astride surgical operation station is fixed, and Self-resetting multi-directional ball
Nest section tilts station chair with the posture of user, when user intends mobile, stands up, gravity brake wheel is no longer locked
Extremely, the both legs of user clamp sit-astride cushion or catch on triangle base with foot, and station chair is driven to move together.
Further, when the centre of sit-astride cushion has through-hole, nobody uses as the lifting part for moving station chair, and
And be conducive to perineum heat dissipation.Sit-astride cushion uses saddle, commercially available, facilitates buying；It is small in size, it is double to be placed in user
Between leg, the posture of leg is influenced small；Softness increases user's comfort level.
First interface components include fixed cylinder and sleeve；Fixed cylinder is fixed on the upper surface of sleeve, is justified by fixed
Column is fixedly connected with the lower surface of sit-astride cushion；Sleeve is fixedly set in the top of lifting atmospheric pressure pole.
