Surgical lithotomy position leg support

Abstract

The invention provides a leg frame for lithotomy position, which includes a side rail clamp, an eccentric locking structure, and a leg support locking structure. The side rail clamp includes a side rail clamp main body, an adjustable clamping block, and a handle assembly. The rail clip is provided with backing plate grooves, which are used to place the backing plate; the eccentric locking structure includes locking devices, hemispherical bearings, eccentric shafts, and eccentric ejector rods, and the eccentric ejector rods include top sheet, connecting rod, stage clip, and tail jack post, and the top sheet is hinged with the connecting rod. The leg frame of the present invention is more stable in clamping, adapts to different operating bedside rails, eliminates the tangential force of the eccentric wheel on the ejector rod, and prolongs the service life of the leg frame. If the tightening device is damaged, the leg rest can be adjusted with multiple degrees of freedom, and the locking method is easy to operate; the structure is beautiful and simple, the operation is simple, and the structure is simple, so as to avoid affecting the operation process.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a leg support for lithotomy position. Background technique [0002] The leg support is an important medical device in lithotomy position surgery. The traditional leg support supports the popliteal part of the patient's leg. Due to the small support area of ​​this kind of leg support, it is easy to cause blood circulation disturbance in the patient's leg. The leg support for the calf support This secondary injury can be avoided, hence the increasing popularity of calf support leg braces. [0003] Operating bed accessories such as leg frames are used by being fixed on the side rails on both sides of the operating bed. For ease of use, the size of the operating bed side rails is generally set in the following specifications: section 30*10mm, 30*8mm, 25* 10mm, 25*8mm, there are two fixing methods of the existing leg frame fixing device: one is the up and down adjustable ...

[0003] Operating bed accessories such as leg frames are used by being fixed on the side rails on both sides of the operating bed. For ease of use, the size of the operating bed side rails is generally set in the following specifications: section 30*10mm, 30*8mm, 25* 10mm, 25*8mm, there are two fixing methods of the existing leg frame fixing device: one is the up and down adjustable screw fixing, this fixing method can only fasten the vertical direction, and cannot fasten the horizontal direction, so the fixation is not firm , once it falls off during the operation, it will cause great harm to the patient; the second is the two-way adjustable screw fixation, although this method can fasten the horizontal and vertical directions at the same time, but the operation is complicated, and the two directions need to be adjusted in coordination, and the pressure area fixed by the screw Small, unstable, and prone to irreversible damage to side rails

[0004] The movement and locking method of the existing lithotomy position leg frame is the cooperation of the eccentric shaft and the eccentric mandrel. Through the working stroke of the eccentric wheel rotation, the hemispherical bearing is moved or locked by the pressure through the eccentric mandrel. However, the existing eccentric shaft The ejector rod in the structure is a simple one-piece column. There are two problems in this des
