Abstract
The utility model provides an operating retractor for front and rear route of cervical vertebrae, thoracic vertebrae and lumbar vertebrae, comprising a fixed arm connected to a movable arm by a rack and a gear meshed with each other. An extension adjuster and a locking element are arranged on the movable arm; a fixed pulling-hook arm and a movable pulling-hook arm are respectively connected to the fixed arm and the movable arm through rotating shafts, micro-surgical pulling boards are fixed on the ends of the fixed pulling-hook arm and the movable pulling-hook arm through protruding pegs and concave grooves. The utility model has good effect on focus exposure, the demand on incision length is lower, thereby, the micro-surgery aim is realized; the utility model is of simple structure, convenient operation, and can be use for the operation on front and rear route of cervical vertebrae, thoracic vertebrae and lumbar vertebrae, and on rear route of spine.
Description
Technical field
This utility model belongs to medical apparatus and instruments, relates to a kind of drag hook of the usefulness of performing the operation, and relates in particular to a kind of neck breast lumbar vertebra front and back road surgery tractor.
Background technology
The surgery tractor of clinical use mostly is metal bending drag hook, needs several assistant's tractive drag hooks in the operation, to reach the purpose that appears surgical field of view.When neck breast lumbar vertebra is performed the operation, after wound retracts, generally need assistant 3-4 people to resist wound tissue's tension force, because the manpower tractive causes otch relatively large, increased artificial infective agent, simultaneously because of also causing the wild instability, unintelligible that exposes of art.
Summary of the invention
It is effective that the novel purpose of this use is to provide a kind of focal zone to expose, and the art open country is neck breast lumbar vertebra front and back road surgery tractor clearly.
The road surgery tractor comprises fixed arm and lever arm before and after the neck breast lumbar vertebra of the present utility model, and described fixed arm is connected by intermeshing tooth bar, gear with lever arm; End at fixed arm and lever arm is connected with fixedly drag hook arm and movable drag hook arm respectively, and is respectively equipped with Wicresoft's arm-tie in the end of fixed arm drag hook and movable drag hook arm.
Be connected by rotating shaft between described fixed arm drag hook and movable drag hook arm and fixed arm and lever arm.
Described fixed arm drag hook and movable drag hook arm and Wicresoft's arm-tie are fixed by the protruding stake and the groove that cooperatively interact.
Described lever arm is provided with expansion and cotraction regulator.
Described lever arm is provided with locker.
This utility model compared with prior art has following beneficial effect:
1, the utlity model has wound little, human body physiological function is disturbed few, effect is parity with or superiority over the characteristics of open surgery, incision length is required lower, has realized the spirit of Minimally Invasive Surgery;
2, this utility model is effective to exposing focus, makes the art open country clear;
3, this utility model wide adaptability can be used for neck, breast, the preceding road of lumbar vertebra and posterior spinal operation.
3, this utility model has reduced assistant's number, and general 2 people just can finish operation, has also reduced the probability of patient's infection of incisional wound simultaneously;
4, utilization structure is simple, easy to operate.
