Description

Technology Field

[0001] The present invention relates to a surgical chair under a microscope. Background Technology

[0002] Chairs used by surgeons or for operating on patients in hospitals must be able to maintain a comfortable posture by taking into account the surgeon's physical characteristics and adapting to various surgical or medical situations.

[0003] In particular, since microscopic surgery, which takes a long time, requires a more precise and stable surgical process, the surgeon sits in a surgical chair and simultaneously operates equipment such as the microscope and Bovie.

[0004] However, conventional surgical chairs for operating microscopes have a problem in that, when operating the foot switch for operating the microscope and Bovie, the gap between the seat where the surgeon sits and the foot switch is wide, and the seat is very large with a fixed backrest, causing the surgeon to have to endure a long surgery while sitting on the edge of the seat.

[0005] In addition, in a surgical environment where a microscope is used, the surgeon must work while observing the surgical site through the microscope with the patient's head fixed. However, since the microscope is positioned far from the patient, the surgeon must perform the surgery in an uncomfortable position, which leads to reduced surgical convenience, increased fatigue, and decreased concentration.

Specific details for implementing the invention

[0022] The advantages and features of the present invention and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below but can be implemented in various different forms; these embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the present invention.

[0024] Unless otherwise defined, all terms used herein (including technical and scientific terms) may be used in a meaning commonly understood by those skilled in the art to which the present invention pertains. Additionally, terms defined in commonly used dictionaries are not to be interpreted ideally or excessively unless explicitly and specifically defined otherwise.

[0025] The present invention will be described in detail below with reference to the attached drawings.

[0026] As illustrated in FIGS. 1 to 5, a surgical chair (1) under a microscope according to one embodiment of the present invention includes a base part (10), a housing (20), a lifting post (25), a seat (30), a footrest (40), a footrest connecting frame (45), and a seat lifting part (50).

[0027] The base part (10) is located at the bottom of the housing (20) and supports the housing (20).

[0028] At the lower part of the base portion (10), a plurality of casters (15) are mounted so as to be rollable on the base portion (10) and to move the base portion (10) along the floor, that is, to move the microscope surgical chair (1) according to one embodiment of the present invention along the floor.

[0029] Some of the casters (15) may be provided with a locking pedal (not shown) to block the rotation of the wheel. For example, the rotation of the caster's wheel can be blocked by pressing one side of the locking pedal, and the blockage can be released by pressing the other side of the locking pedal. This prevents shaking or slipping during surgery, thereby providing a safe surgical environment.

[0030] In this way, by providing multiple casters (15), the position can be freely changed within the operating room, thereby improving the convenience of the surgery.

[0031] The housing (20) is installed upright on the upper part of the base (10), with the seat (30) spaced apart from the base.

[0032] The lifting post (25) is formed to be long vertically.

[0033] The lower part of the lifting post (25) is installed by inserting it into the interior of the housing (20), and the upper part of the lifting post (25) is exposed to the outside of the housing (20).

[0034] The lifting post (25) moves up and down, for example, by the seat lifting part (50).

[0035] The configuration of the seat lifting unit (50) will be described later.

[0036] The seat (30) is attached to the upper part of the lifting post (25) so that the surgeon can sit on it.

[0037] The seat (30) may be provided with a cushioning material such as a sponge or foam resin inside to reduce fatigue and provide comfort even when the surgeon sits for a long time.

[0038] A pair of footrests (40) have a flat, rectangular plate shape on which the surgeon's feet are placed.

[0039] A pair of footrests (40) are placed between the base (10) and the seat (30).

[0040] The footrest (40) may be provided with an anti-slip pad (41) to prevent slipping.

[0041] Here, although not illustrated, as an example, a foot switch may be placed on a foot to perform microscopic surgery, and the foot may have various sizes corresponding to the size of the foot switch placed on the foot.

[0042] The footrest connecting frame (45) is made up of a pair and has a rod shape of a certain length formed vertically.

[0043] One end of the footrest connecting frame (45) is connected to the bottom of the seat (30), and the other end is connected to the top of the footrest (40).

[0044] Thus, the seat (30) and the footrest (40) are integrally connected by the footrest connecting frame (45).

[0045] Meanwhile, a hinge member (not shown), such as a hinge pin, is provided at the lower end of each footrest connecting frame (45), so that a pair of footrests (40) can be detachably and rotatably connected. Here, each footrest (40) has a size such that no interference occurs with the housing (20) and the lifting post (25) when the footrest (40) rotates.

[0046] In this way, as the footrest (40) is detachably coupled to the footrest connecting frame (45), footrests (40) of various sizes can be selectively mounted and used in correspondence with the size of the footrest switch placed on the footrest (40).

[0047] In addition, as the footplate (40) is rotatably coupled to the footplate connecting frame (45), the arrangement angle of a pair of footplates (40) can be adjusted to a desired angle as shown in FIG. 8, allowing the position of the foot to be freely changed and surgery to be performed. Furthermore, by adjusting the angle of the footplate (40) to match the ankle angle of the surgeon, ankle fatigue can be minimized and surgery can be performed while maintaining a comfortable posture.

[0048] The seat lifting unit (50) includes a seat lifting drive unit (51) installed inside the housing (20) to raise and lower a lifting post (25), and an operating pedal (53) installed on the base unit (10) to operate the seat lifting drive unit (51).

[0049] Here, as a seat lifting drive unit (51), a conventional gas spring may be applied, in which a spring is contained within a cylinder containing compressed gas, and the spring automatically provides restoring force and compressive force by compressing the gas inside the cylinder, for example, by utilizing the force in which the spring is automatically compressed or expanded by the pressure of the gas. Accordingly, the lifting post (25) can be raised or lowered by utilizing the restoring force or compressive force of the spring generated by the expansion or compression of the spring according to the operation of the operating pedal (53) for operating the gas spring.

[0050] Additionally, although not illustrated, a motor and a lead screw may be applied as the seat lifting drive unit. In this case, various known structures may be applied to convert the rotational force of the motor into the vertical movement of the lifting post. For example, the lifting post may be moved up and down by rotating a lead screw, which is screw-coupled to the lower part of the lifting post, by means of a motor.

[0051] In this way, by simultaneously raising and lowering the seat (30) and the footrest (40), the surgeon can sit in a desired position according to the surgical situation and the surgeon's physical condition, thereby performing surgery in a stable position, improving the convenience of the surgery, reducing the surgeon's fatigue, and improving the surgeon's concentration.

[0052] In addition, a surgical chair (1) under a microscope according to one embodiment of the present invention may include a pair of armrests (60) on which both arms are supported, and an armrest adjustment unit (70) for swivel, raise, and tilt the armrests (60) relative to the seat (30).

[0053] The armrest adjustment unit (70) includes a seat frame (71), an armrest bracket (75), a link (81), a connecting joint (85), an armrest driving unit (91), and an operating lever (95), as shown in FIGS. 6 and 7.

[0054] The sheet frame (71) has a rod shape with a bent central area and is provided on one side of the sheet (30).

[0055] One end of the seat frame (71) is supported at the bottom of the seat (30), and the other end does not interfere with the seat (30) and protrudes at a position higher than the seat (30) on one side of the seat (30).

[0056] The armrest bracket (75) is connected to one side of the lower portion of the armrest (60). The armrest bracket (75) is connected by a hinge member (77), for example, by a step hinge that rotates stepwise by a certain angle as a hinge member (77), so that the armrest (60) can be tilted.

[0057] A seat frame (71) is connected to one end of the link (81), and an armrest bracket (75) is connected to the other end, so that the seat frame (71) and the armrest bracket (75) are interconnected.

[0058] One end of the link (81) is swivelly connected to the seat frame (71) by a connecting joint (85) and is also movably formed along the inner side of the connecting joint (85).

[0059] Accordingly, the link (81) has a radius of rotation corresponding to the gap between one end of the link (81) and the other end of the link (81), such as the gap between the connecting joint (85) and the armrest bracket (75), and the link (81) swivels around the connecting joint (85) and moves up and down along the inside of the connecting joint (85).

[0060] The armrest drive unit (91) is attached to the armrest bracket (75) and raises the link (81) relative to the seat frame (71).

[0061] This armrest drive unit (91) is provided to be inclined upward at an acute angle with respect to the bottom surface of the armrest (60).

[0062] Here, as an armrest drive unit (91), a conventional gas spring may be applied, in which a spring is contained within a cylinder containing compressed gas, and the spring automatically provides restoring force and compressive force by compressing the gas inside the cylinder, for example, by utilizing the force in which the spring is automatically compressed or expanded by the pressure of the gas. Accordingly, the armrest (60) can be raised or lowered by utilizing the restoring force or compressive force of the spring generated by the expansion or compression of the spring according to the operation of the operating lever (95) for operating the gas spring.

[0063] Accordingly, when the operating lever (95) is operated so that the force generated by the armrest drive unit (91) is applied upward to the armrest (60), the link (81) rises along the inner side of the connecting joint (85), and the armrest (60) rises to a certain height relative to the seat (30).

[0064] Conversely, when the operating lever (95) is operated so that the force generated by the armrest drive unit (91) is applied toward the lower side of the armrest (60), the link (81) descends along the inner side of the connecting joint (85), and the armrest (60) descends to a certain height relative to the seat (30).

[0065] Then, when the surgeon pushes the armrest (60) toward the rear of the microscopic surgical chair (1), the link (81) swivels toward the rear of the microscopic surgical chair (1) around the connecting joint (85), so that the armrest (60) is positioned at the rear of the microscopic surgical chair (1).

[0066] Conversely, when the surgeon pulls the armrest (60) toward the front of the microscopic surgical chair (1), the link (81) swivels toward the rear of the microscopic surgical chair (1) around the connecting joint (85), so that the armrest (60) is positioned at the front of the microscopic surgical chair (1).

[0067] Additionally, when the surgeon tilts the armrest (60) relative to the horizontal, the armrest (60) can be tilted at a certain angle in the direction in which force is applied by the hinge member (77).

[0068] Thus, by adjusting the armrest (60) according to the surgical situation and the height of the surgeon's arm, the fatigue of the shoulder and neck can be reduced and accurate surgery can be performed.

[0069] In addition, the angle of the armrest (60) can be adjusted according to the angle of the arm to reduce the strain on the elbow and wrist and maintain a stable posture.

[0070] In this way, the armrest (60) can be adjusted to swivel, lift, and tilt, thereby securing the surgical space, improving joint mobility, improving the convenience of manipulating surgical tools, reducing fatigue of the surgeon, and improving concentration during surgery.

[0071] And, a surgical chair (1) under a microscope according to one embodiment of the present invention may include a backrest (100) that supports the back of a surgeon seated on a seat (30) as shown in FIG. 2, a backrest frame (110) that supports the backrest (100), a backrest bracket (120) to which the backrest frame (110) is connected, and a seat bracket (130) that connects the backrest bracket (120) and the seat (30).

[0072] The backrest frame (110) has a bar shape of a certain length and is provided on the back surface of the backrest (100) and is positioned upright relative to the seat (30).

[0073] The backrest bracket (120) and the seat bracket (130) are rotatably connected by the backrest (100), and a torsion spring (not shown) that generates elastic force on the backrest bracket (120) may be provided around the backrest (100).

[0074] Thus, when force is applied to the backrest (100) towards the rear of the seat (30) while the backrest (100) is positioned vertically relative to the seat (30), the backrest bracket (120) tilts around the backrest (100), causing the backrest (100) to tilt relative to the seat (30), and at this time, the torsion spring is tensioned. Conversely, when the force applied to the backrest (100) towards the rear of the seat (30) is removed, the torsion spring is compressed, and the backrest (100) is restored to its original position by the elastic restoring force of the torsion spring.

[0075] In this way, by adjusting the angle of the backrest (100) to match the spinal curve of the surgeon, the burden on the lower back is minimized, and surgery can be performed in a comfortable position.

[0076] Here, although not illustrated, the backrest frame may be provided with a lumbar support to support the surgeon's lumbar spine.

[0077] In addition, the backrest (100) of the surgical chair (1) under a microscope according to one embodiment of the present invention may include a plurality of coupling holes (141) formed at intervals along the longitudinal direction of the backrest frame (110), and a coupling projection (145) provided on the backrest frame (110) and coupled to one of the plurality of coupling holes (141).

[0078] Here, the coupling hole (141) is formed as a recess with a hemispherical cross-sectional shape, and the coupling projection (145) has a cross-sectional shape and size corresponding to the coupling hole (141) and can be formed to protrude toward the backrest frame (110).

[0079] Accordingly, by connecting a connecting projection (145) to one of the multiple connecting holes (141) formed at intervals along the longitudinal direction of the backrest frame (110), the backrest frame (110) can be raised and lowered along the backrest bracket (120), thereby allowing the height of the backrest (100) to be adjusted relative to the seat (30).

[0080] Accordingly, the height of the backrest (100) is adjusted to suit the surgical situation and the surgeon's sitting height, thereby effectively supporting the waist and back and allowing the surgery to be performed while maintaining a stable posture.

[0081] Thus, according to the present invention, by sitting in a desired position tailored to the surgical situation and physical condition, surgery can be performed in a stable position, thereby improving surgical convenience, reducing fatigue of the surgeon, and enhancing surgical concentration.

[0082] Meanwhile, in the above-described embodiment, the present invention is described as being applied to a surgical chair under a microscope as one embodiment, but is not limited thereto, and the technical concept according to the present invention can be applied to a chair equipped with a seat, armrests, a backrest, and a footrest.

[0083] Although embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will understand that the present invention may be implemented in other specific forms without altering its technical concept or essential features. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. Explanation of the symbols
