Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a novel pre-clamping fixator. Background Technology

[0002] During surgery, operating table accessories such as leg supports and hand supports need to be fixed to the operating table tracks. Therefore, clamps are required to secure these accessories to the tracks. Because these accessories are frequently repositioned according to surgical needs, they require frequent disassembly. Therefore, the clamps and operating table tracks are designed with appropriate gaps. However, the locking screws of existing clamps are perpendicular to the operating table tracks. Consequently, even after tightening, a gap still exists between the operating table tracks and the clamps, particularly in the axial direction perpendicular to the locking screws. This gap causes wobbling during use, affecting the surgical procedure.

[0003] For example, Chinese patent document CN213250841U, published on May 25, 2021, discloses a clamp for fixing an operating table accessory, which includes an operating table track, an operating table accessory, a clamp body, a locking screw, and a handle. The clamp body includes a main body, two openings, two grooves, and a threaded hole. The axial direction of the threaded hole is perpendicular to the arrangement direction of the two openings and forms an acute angle with the arrangement direction of the two grooves; simultaneously, the axial direction of the threaded hole and the arrangement direction of the grooves are located on the same plane. This causes the locking screw to lock the clamp body, generating two directional forces: a first directional force perpendicular to the arrangement direction of the two openings and directed towards the operating table track, and a second directional force perpendicular to the first directional force and directed towards the arrangement direction of the two grooves. Under the cooperation of the first and second directional forces, the clamp body fixes the operating table track and the operating table accessory, eliminating gaps.

[0004] However, the above technical solution has a fixed opening size for the clamp, which means that the clamp can only be put into the head of the leg plate, hand plate, etc., which limits the application scenarios; at the same time, the fixed opening size of the clamp makes it easy to slip off the leg plate, hand plate, etc.

[0005] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content

[0006] The purpose of this utility model is to provide a new type of pre-clamping fixture, which solves the technical problem that existing clamps can only be put into the head of the leg plate, hand plate, etc., and have limited application scenarios; and solves the technical problem that existing clamps are prone to slipping off the leg plate, hand plate, etc. when the opening size is fixed.

[0007] This utility model provides a novel pre-clamping fixture, comprising a clamp body, a movable component, a locking bolt, a spring, and a push rod. The lower end of the clamp body is provided with a connecting groove, in which two mounting holes are provided. The spring and the push rod are installed in the mounting holes. One end of the movable component is provided with a connector, and two slots that mate with the push rod are provided on the side of the connector. The connector engages in the connecting groove, and the push rod rests in the slot. A threaded hole is provided in the middle of the clamp body, and the locking bolt is threaded into the threaded hole. An accessory mounting groove is provided at the front of the clamp body, and the accessory mounting groove is perpendicular to the length direction of the clamp body.

[0008] Using the above technical solution, the operating table accessory 800 is inserted into the accessory mounting slot during use, and the operating table track is clamped between the clamp body and the movable part. The operating table accessory and the operating table track are perpendicular to each other. The rotating locking bolt causes the end of the rotating locking bolt to press against the operating table accessory. At the same time, the design of the movable part, spring and push rod allows the movable part to rotate around the connecting slot, and the spring will push the push rod to provide the movable part with the force to clamp the operating table track.

[0009] Furthermore, the novel pre-clamping retainer also includes a handle, which is spherical and connected to the end of the locking bolt. The surface of the handle is provided with multiple anti-slip grooves.

[0010] Furthermore, the upper end of the clamp body is provided with two upper hooks, which are perpendicular to the front of the clamp body; the lower end of the clamp body is provided with two lower hooks that cooperate with the upper hooks, which are perpendicular to the front of the clamp body; the outer surface of the lower hooks is provided with an arc-shaped surface.

[0011] Furthermore, the cross-section of the movable component is generally arc-shaped, and a movable component hook is provided at one end of the movable component away from the connector; an arc-shaped groove is provided on the inner surface of the movable component; when the connector is engaged in the connecting groove, the arc-shaped groove wraps around the arc-shaped surface.

[0012] This novel pre-clamping fixture, in use, involves inserting the operating table accessory into the accessory mounting slot. The operating table track is clamped between the fixture body and the movable component, with the operating table accessory and the operating table track perpendicular to each other. A rotating locking bolt causes its end to press against the operating table accessory and the operating table track. Simultaneously, the design of the movable component, spring, and push rod allows the movable component to rotate around the connecting slot, while the spring pushes the push rod to provide clamping force to the movable component onto the operating table track. This fixes the operating table track and operating table accessory, eliminating gaps. Furthermore, the adjustable opening size of the fixture solves the technical problem of existing fixtures only being able to be inserted through the head of leg panels, hand panels, etc., limiting their application scenarios. The spring pushes the push rod to provide clamping force to the movable component onto the operating table track, solving the technical problem of existing fixtures easily slipping off leg panels, hand panels, etc., when the opening size is fixed.
