Abstract
The utility model relates to a retractor special for a craniocerebral operation. The retractor comprises a left forceps handle and a right forceps handle which are connected rotatably. The two forceps handles are locked through a rack and a locking gear. Retracting arms extend from the front ends of the two forceps handles, and retracting palms are respectively arranged at the front ends of the two retracting arms. Adjusting holes are distributed on the connecting end of the left retracting palm which is locked on the left retracting arm through a bolt. A guide chute is arranged on the inner face of the left retracting arm. Adjusting holes are distributed on the inner wall of the guide chute which is internally provided with a brain spatula sliding along the guide chute. The brain spatula is locked in the guide chute through the bolt. The front end of the brain spatula extends from the front end of the left retracting palm, and retracting jaws are distributed on the lower end face of the left retracting palm. The right retracting palm is symmetrical to the left retracting palm. According to the retractor provided by the utility model, the problem that the view exposed in operation is inadequate for the current retractor is effectively solved, and the problem that the operational time is prolonged and the operational quality is decreased because the current retractor is unreasonable in structure is solved.
Description
Technical field
This utility model relates to a kind of medical instruments, especially a kind of craniocerebral operations Special retractor.
Background technology
Also there is no clinically at present special-purpose cranium drawing means for brain tissue, usually need during craniocerebral operations fully to expose surgical field of view, have to select the laminectomy retractor of lumbar surgery to retract operation, wound is fully exposed; Like this, often the model size due to laminectomy retractor is improper, must repeatedly select the large ting model of drag hook, usually there is no suitable drag hook model, surgical field of view can't fully be exposed, just must increase the assistant and carry out tractive, so not only increased doctor's labor intensity and extended operating time, and having had influence on sometimes the mood of operator, thereby might cause the Quality Down of performing the operation.
Summary of the invention
The utility model proposes a kind of craniocerebral operations Special retractor, effectively solved existing retractor surgical field of view and exposed inadequate problem, and existing retractor extends because of operating time that unreasonable structure causes and the problem of operation Quality Down.
in order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: a kind of craniocerebral operations Special retractor, comprise left clamp handle and right clamp handle, left clamp handle and right clamp handle are rotatedly connected, be provided with the lock tooth bar on right clamp handle, be provided with on left clamp handle and the lock tooth of locking tooth bar and matching, the front end of left clamp handle is extended with left drawing arm, the front end of right clamp handle is extended with right drawing arm, it is characterized in that: the front end of two drawing arms be respectively equipped with a left side retract the palm and the right side retract the palm, a left side retracts on the link of the palm and is distributed with the adjusting screw, regulate in screw bolt is housed, a left side retracts to be slapped by bolt-locking on left drawing arm, the medial surface that a left side retracts the palm is provided with guide chute, be distributed with adjustment hole on the inwall of guide chute, be provided with the brain spatula of sliding along guide chute in guide chute, the tail end of brain spatula is equipped with the bolt that is spirally connected with adjustment hole, brain spatula by bolt-locking in guide chute, the front end of brain spatula retracts the palm from a left side front end stretches out, a left side retracts to be distributed with to retract on the lower surface of the palm and grabs, the described right side retracts the palm and retracts palm symmetrical configuration with a left side.
To the further improvement of technique scheme, described lock tooth bar is provided with chute, is provided with bolt in chute, and bolt and the screwed hole that is arranged on left clamp handle are spirally connected, the lock tooth bar by bolt-locking on left clamp handle.
Beneficial effect: of the present utility model retract the palm have can stretch can be bent function, the depth according to operative incision, regulate the radian that retracts the palm and drawing arm by bolt, effectively having solved otch causes surgical field of view to expose inadequate problem deeply, retract the palm and the angle that drawing arm forms, be conducive to retractor and easily be fixed on the cranium brain; The brain spatula that retracts palm has Telescopic, according to the length of operative incision, regulates the collapsing length of brain spatula by bolt, has effectively solved otch and has caused greatly surgical field of view to expose inadequate problem; In order to strengthen the stability of retractor, be provided with the bolt chute on the lock tooth bar, the lock tooth bar by bolted on clamp handle, thereby strengthened the stability of retractor, the end that retracts of retractor is controlled in an immutable scope; This utility model is compared with traditional retractor, adopt the craniocerebral operations Special retractor of pincerlike structure, because of simple in structure, be convenient to operator convenient retractor of regulating in art, labor intensity and operating time have effectively been reduced, operator is completed high-quality work in easily joyful, use complicated problem thereby solved existing retractor.This utility model is simple in structure, and is easy to use, and cost of manufacture is low.
