Retractor frame for lithotomy position operation

Abstract

The invention discloses a retractor frame for the lithotomy position operation. The retractor frame comprises a big chuck, a small chuck and two arc draw hooks with half-moon-shaped chutes. The upper surface of the retractor frame is of a plane structure. The lower surface of the retractor frame is of a point-like round ball structure. The middles of outer rings of the two chucks are provided with knurled fastening screws. Clamping grooves are arranged on a border of the retractor frame at intervals and are used for fixing clamping bead chain draw hooks. The small chuck extends outwards to form two forkheads. Countersunk head locking screws and butterfly nuts which cannot be screwed out are arranged on the forkheads. The two arc draw hooks are provided with the half-moon-shaped chutes. The half-moon-shaped chutes are used for positioning the arc draw hooks. Round mouths are arranged in the half-moon-shaped chutes of the two arc draw hooks and are used for ensuring the arc draw hooks to be sleeved in. The retractor frame can be disinfected at a high temperature under high pressure. Not only is the cost of the operation reduced, but also the retractor frame is convenient to maintain. The retractor frame has popularization value.

Description

technical field [0001] The invention relates to an instrument for convenient operation, in particular to a retractor frame for convenient operation in lithotomy position. Background technique [0002] Fully exposing the surgical incision and expanding the visual field is one of the important factors for the success of the operation. The patient in the lithotomy position lies supine, and the surgeon cannot stand up to perform the operation. It is even more impossible for multiple people to perform aseptic operation, making it difficult to perform effective surgery. Contents of the invention [0003] In order to solve the above problems, the present invention provides a convenient retractor frame for lithotomy position surgery. The patient's body position is fixed, and the surgical incision is pulled open with the help of a bead chain pull hook, so that the surgical incision is fully exposed, and the operator's field of vision is enlarged, and the surgical incision is omitted...
