Draw hook locking device with movable arm

Abstract

A draw hook locking device with a movable arm comprises a draw hook locking part and a base, wherein the base is connected with the draw hook locking part and has position fixing and adjusting effects. The draw hook locking part comprises a draw hook assembly, a movable arm, a base connecting assembly and a locking control assembly which are sequentially connected. A steel wire rope which penetrates through the movable arm and the base connecting assembly and is used for transmitting control torque is connected between the locking control assembly and the draw hook assembly. The movable arm comprises a plurality of ball heads at intervals and columnar connecting blocks, wherein spherical surface grooves matched with the ball heads are formed in the two ends of the columnar connecting blocks. The draw hook locking device is compact and practical in structure, convenient to operate and use, capable of being widely used for fixing devices in clinical medical treatment, capable of being conveniently fixed, detached and assembled, and capable of flexibly moving devices through the movable arm and effectively improving clinical operation efficiency; the clamping and supporting strength of the whole device is easy to adjust, the draw hook locking device can be used for fixing various devices, and the operation hand feeling can be adjusted according to demands of a user.

Description

technical field [0001] The invention relates to a locking device, in particular to a drag hook locking device with a movable arm. Background technique [0002] With the increasingly tense relationship between doctors and patients, people are calling for the reform and improvement of the medical system and medical level; reforming the medical system can fundamentally solve the contradiction between doctors and patients, but the effect is relatively slow; improve medical level and efficiency It can immediately relieve the current tense doctor-patient relationship. [0003] Improving the level and efficiency of medical treatment urgently requires the innovation of medical equipment and clinical treatment methods, especially in cases such as surgery, which is time-consuming, high-precision, and requires a lot of equipment. Innovation is particularly effective in improving the efficiency of surgery. [0004] At present, surgical instruments and instruments are classified and pla...

AI Technical Summary

Problems solved by technology

[0004] At present, surgical instruments and instruments are classified and placed according to the surgical process. They all need professional assistance to fix or operate, and as the operation progresses, the positions of the instruments need to be adjusted and fixed frequently at any time. Not only is the operation difficult, but the stability is poor. Some adverse consequences can also be caused by human error; therefore, reducing the difficulty of adjusting and fixing the position of the above-mentioned devices is of great significance to the improvement of medical efficiency
