Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of thoracic surgery surgery tractor.
Background technology
At present, in thoracic surgery therapeutic process, need to cut skin, subcutaneous tissue, Musclar layer, enter thoracic cavity by narrow intercostal space and complete hands art, intercostal space needs to draw expanded support by hand, such operator are many, bothersome effort, labor intensity and work difficulty is added to medical worker, in order to solve this technical problem, notification number is that the utility model patent of CN203873809U discloses a kind of surgery tractor for thoracic surgery, although this device serves certain effect in actual applications, but still have the following disadvantages: 1, whole device is frame structure, a large amount of spaces is occupied when not using, 2, need in use manually to adjust the distance between drag hook, operate very inconvenient, 3, in use procedure when regulating the width of traction, if the distance between drag hook is excessive, like this will the rib of injured patients, and the position of drag hook is changeless, is difficult to find suitable support point when strutting rib.
Portioned product is improved, such as Chinese patent discloses a kind of New pattern chest surgery operation drag hook, application number: 201420771925.1, the applying date: 2014-12-10, this utility model solves the technical scheme that its technical problem adopts: a kind of New pattern chest surgery operation drag hook, comprise two supports, wherein said support two ends are connected by support bar, control chip is provided with in described support, told support is respectively equipped with alignment pin and chute, described chute is provided with locating hole, slide block is provided with in described chute, told slide block is provided with the via hole with described locating hole formed objects, expansion link is provided with in described slip front, rotating shaft is provided with at the other end of told expansion link, told rotating shaft is provided with drag hook, pulling force sensor is provided with inside described drag hook, tell control chip input be connected with joystick and pulling force sensor of telling, outfan is connected with described expansion link.
The deficiency of technique scheme is: 1, inside described drag hook, be provided with pulling force sensor, due to local pressure causes pressure sensing can not the stressing conditions of effecting reaction drag hook entirety; 2, control chip is arranged in support, and all pulling force sensors and expansion link are all controlled by same control chip, once chip goes wrong, whole system will quit work, extreme danger in operation.
Summary of the invention
For the deficiencies in the prior art, this utility model provide a kind of can the thoracic surgery surgery tractor that all independently controls of the overall stressing conditions of effective monitoring drag hook and each expansion link.
The technical solution of the utility model is:
A kind of thoracic surgery surgery tractor, comprise support, support bar, drag hook, it is characterized in that: described support has two, connected by two support bars between two supports, support is respectively equipped with some alignment pins and chute, described chute is provided with locating hole, slide block is provided with in described chute, slide block is provided with the via hole with described locating hole formed objects, expansion link is provided with in described slip front, rotating shaft is provided with at the other end of described expansion link, described rotating shaft is provided with drag hook, pulling force sensor is provided with between drag hook base portion and rotating shaft, often overlap expansion link, pulling force sensor respectively correspondence is provided with a control chip and joystick, joystick described in the input of described control chip is connected by electric wire and described pulling force sensor, its effect be pulling force sensor by being arranged on drag hook base portion solve local pressure can not the problem of the overall stressed degree of drag hook anyway, by often overlapping expansion link, pulling force sensor is corresponding is respectively provided with a control chip and joystick solves the problem that chip piece damage can affect whole plant running.
Further, described support bar and support adopt detachable connection, and described support bar is telescopic, and its effect is that the storage being convenient to installing/dismounting and apparatus is preserved.
Further, described control chip is arranged in joystick, and its effect is the replacing being convenient to whole control system.
Further, on the support that what described joystick was detachable be arranged on corresponding expansion link position, doctor's real-time operation is convenient in its effect.
Further, described joystick is button, and described joystick surface againsts disposable protecting film, and its effect is that blood when avoiding surgical or other liquid infiltrate wiring board and Environmental capacity handle.
The beneficial effects of the utility model are: this utility model is reasonable in design, solving local pressure by the pulling force sensor being arranged on drag hook base portion can not the problem of the overall stressed degree of drag hook anyway, and by often overlapping, expansion link, pulling force sensor are corresponding is respectively provided with a control chip and joystick solves the problem that chip piece damage can affect whole plant running.
