[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] like Figure 1 to Figure 4As shown, the new lithotomy leg stand of the utility model comprises: a leg boot 1, a leg support locking slider 2, a cantilever 3, a large arm 4, a support rod 5, a locking handle 6, a spherical joint connecting rod 7 and a spherical joint base 8; wherein, the leg boot 1 is connected to the middle part of the cantilever 3 through the leg support locking slider 2 and can be linearly moved or rotated along the cantilever 3 for adjustment; two places at one end of the cantilever 3 are respectively hinged to the large arm 4 and the support rod 5, and similarly, the spherical joint base 8 is also respectively hinged to the large arm 4 and the support rod 5, and the locking handle 6 is used to lock the support rod 5, so as to further realize the positioning of the cantilever 3 and the large arm 4, and finally realize the position adjustment of the leg boot 1; the spherical joint base 8 is spherically connected to the spherical joint connecting rod 7 and is connected to the external operating bed side rail through the spherical joint connecting rod 7, so as to realize the installation and fixation of the leg stand.

[0029] Specifically, the leg support locking slider 2 connects the leg boot 1 and the cantilever 3. The leg support locking slider 2 is provided with a rotating handle. By loosening the handle, the boot can be moved forward and backward, turned left and right, and rotated itself. By locking the handle, the boot can be positioned.

[0030] The cantilever 3 is used to support the leg boot 1. The cantilever 3 is composed of a cylindrical rod and a tripod. One end of the tripod is fixedly connected to the cylindrical rod. The second end of the tripod has a circular hole 31 for hingedly connecting to the upper end of the support rod 5. The third end of the tripod has a circular hole 2 32 for hingedly connecting to the upper end of the upper arm 4.

[0031] like Figure 3 , Figure 4 As shown, the spherical joint base 8 is in the shape of a rectangular parallelepiped as a whole, and has a pin hole 81 at the upper right corner of the spherical joint base 8 for hinged connection with the lower end of the upper arm 4. The upper left part of the spherical joint base 8 has a splint 1 82 and a splint 2 87, forming a U-shaped structure, and the lower ends of the splint 1 82 and the splint 2 87 are not connected to the bottom of the spherical joint base 8, and are divided by a dividing groove 86, so that the splint 1 82 and the splint 2 87 have a certain elasticity, which is convenient for changing the distance between the two.

[0032] The inner sides of the clamping plate 1 82 and the clamping plate 2 87 are both provided with a hemispherical groove 83, which cooperates with the ball head 51 at the lower end of the support rod 5; at the same time, the clamping plate 1 82 has a threaded hole 84, and the clamping plate 2 87 has a through hole.

[0033] The locking handle 6 has a handle portion and a locking portion, which are combined to form an L-shaped structure. The front end of the locking portion has a threaded rod 62 that cooperates with the threaded hole 84, the rear end of the locking portion cooperates with the through hole, and the middle of the locking portion has a crankshaft protrusion 61.

[0034] When the locking handle 6 and the support rod 5 are respectively installed on the spherical joint base 8, the ball head 51 at the lower end of the support rod 5 cooperates with a pair of hemispherical grooves 83, and the threaded rod 62 cooperates with the threaded hole 84; by rotating the locking handle 6 to shorten the distance between the clamping plate 1 82 and the clamping plate 2 87, the ball head clamped between the pair of hemispherical grooves 83 is clamped to achieve the positioning of the support rod 5; further achieve the positioning of the cantilever 3 and the upper arm 4, and finally achieve the position adjustment of the leg boot 1. In addition, at a certain moment in the process of rotating the locking handle 6, the crankshaft protrusion 61 will conflict with the spherical surface of the ball head 51 to achieve further locking and fixing.

[0035] like Figure 4 , Figure 7 As shown, the spherical joint connecting rod 7 includes a fixing rod 71 connected to an external mounting bracket, a spherical joint 72 and a connecting plate therebetween; the fixing rod 71 is connected to the external operating bed side rail; a spherical groove 85 is provided at the lower right end of the spherical joint base 8, and the spherical groove 85 matches the shape of the spherical joint 72, so as to realize up and down movement and small inward and outward movement. The use of the spherical joint makes the overall range of movement of the leg frame larger, increases the space for inward and outward movement, and is more adaptable.

[0036] The locking mechanism of the present invention adopts a U-shaped structure with an adjustable opening gap, and the locking handle can lock the support rod and the spherical joint connecting rod at the same time. The spherical joint connecting rod and the support rod both adopt a clamping locking structure. When the locking handle is turned clockwise, the clamping device will be locked, and the clamping device will automatically clamp the spherical joint connecting rod, and clamp the support rod by rotating the thread to achieve locking; when the locking handle is turned counterclockwise, the internal structure of the locking handle will push open the clamping device, loosen the screw rod, loosen the support rod, loosen the clamping device, and allow the spherical joint connecting rod and the support rod to move freely.

[0037] The spherical joint base 8 connects the support rod 5 and the spherical joint connecting rod. By loosening the handle, the upper arm, the support rod and the spherical joint connecting rod can be moved. By locking the handle, the support rod and the spherical joint connecting rod can be fixed to achieve the overall fixation of the leg frame. This structure adopts mechanical structure locking, which is more firm, has a longer service life and is easy to use.

[0038] The working principle and working process of the novel lithotomy position leg frame of the utility model are briefly described below in conjunction with the accompanying drawings.

[0039] The leg frame of the present invention adopts a design that imitates the human body joint structure, specifically adopts a structure that combines a large arm, a cantilever and a support rod, so that the leg frame is more stable and flexible, and has greater supporting power. It can also be laid flat and a bed support plate can be placed on it to replace part of the bed, which is more practical. At the same time, a new appearance design is adopted, which is more beautiful.

[0040] The cantilever 3 supports the leg boot 1 through the leg support locking slider 2, one end of the cantilever 3 is hinged to the upper arm 4 and the support rod 5, and the spherical joint base 8 is also hinged to the upper arm 4 and the support rod 5; Figure 5 As shown, the included angle between the cantilever 3 and the boom 4 is in the range of 67° to 180°, that is, the maximum adjustable angle of the cantilever 3 relative to the boom 4 can reach 113°.

[0041] like Figure 6 As shown, the upper arm 4 and the support rod 5 are respectively connected to the spherical joint base 8, and the spherical joint base 8 and the spherical joint connecting rod 7 are connected by a spherical pair; so that the angle of the upper arm 4 relative to the spherical joint connecting rod 7 is 90°~225°; that is, the maximum adjustable angle of the upper arm 4 can reach 135°.

[0042] In addition, if Figure 7 As shown in the figure, the spherical joint connection method can realize the inward and outward movement and the upward and downward movement of the leg frame. The horizontal adjustment of the spherical joint has an outward angle range of 0° to 25°; the inward angle range is 0° to 8°. The use of the spherical joint makes the overall range of movement of the leg frame larger, increases the space for inward and outward movement, and is more adaptable.

[0043] The novel lithotomy leg frame provided by the utility model also has the following characteristics:

[0044] 1. This technology adopts a flexible human-like joint structure, which is easy to operate, light and convenient, with flexible surgical positions, improved surgical efficiency and safety, reduced the workload of medical workers, and has stronger environmental adaptability. It is a reliable partner for medical workers.

[0045] 2. This technology abandons the support structure of the pneumatic rod and adopts the design of a large arm plus a support rod, which has greater support strength and is suitable for people with large weights. It has a long service life and is safer and more stable to use, so that medical workers can use it with confidence.

[0046] 3. This technology adopts a large arm support design. When the leg frame is laid flat, a bed support plate is placed on it to replace part of the bed. This avoids damage to the bed and leg frame due to frequent disassembly, reduces the workload of medical staff, and is more practical.

[0047] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
