Abstract
The invention discloses a thoracoscope surgery cannula, which belongs to the technical field of medical devices. The technical scheme of the invention is as follows: the thoracoscope surgery cannula comprises a cannula body, and the thoracoscope surgery cannula is characterized in that a closed ice water cannula is arranged at the outside of the cannula body, a 1cm-long cannula is arranged at the external side of the closed ice water cannula, and two ends of the cannula are provided with four 1cm-long symmetrical elastic location arms; the middle section of the cannula is provided with a location nut horizontal to the elastic location arms, the front section of the closed ice water cannula and the surfaces of the elastic location arms are provided with smooth oil jackets, and the rear end of the closed ice water cannula is provided with a fixing handle. The thoracoscope surgery cannula is simple in structure and can avoid the longitudinal movement of the cannula while the thoracoscope surgery for the patient is performed, so that the coagulation of the exuded blood can be avoided, the tissues are prevented from being bonded with the external wall of the cannula body, and difficulty in the work of the medical personnel is reduced.
Description
Technical field: the invention belongs to the medical instruments technical field, is a kind of Thoracoscope surgery cannula specifically.
Background technology: at present, when carrying out thoracoscopic operation to patient, need to insert first sleeve pipe at the incision intercostal clinically, this sleeve surface is without fixation means, sleeve pipe moves up and down easily when operation, sometimes the static operating time is slightly long, the surface is oozed out blood and is solidified easily, and the easy and tube wall adhesion of tissue has increased work difficulty to the medical worker.
Summary of the invention: the purpose of this invention is to provide and a kind ofly when carrying out thoracoscopic operation to patient, can avoid sleeve pipe to move up and down, and can avoid oozing out the Thoracoscope surgery cannula of blood coagulation and tissue and tube wall adhesion.
Technical scheme of the present invention is: comprise body, it is characterized in that outside body, being provided with airtight frozen water pipe, it is 1 centimetre sleeve pipe that the airtight frozen water pipe outside is provided with length, it is 1 centimetre and four symmetric elastic force registration arm that the sleeve pipe two ends are provided with length, elastic force registration arm direction with respect to sleeve pipe radially outward, the horizontal level of sleeve pipe stage casing and elastic force registration arm is provided with setscrew nut, airtight frozen water pipe leading portion and elastic force registration arm surface are provided with smooth oil jacket, and airtight frozen water pipe rear end is provided with fixed handle.
The invention has the beneficial effects as follows: the present invention is simple in structure, can avoid sleeve pipe to move up and down when carrying out thoracoscopic operation to patient, and can avoid oozing out blood coagulation and tissue and tube wall adhesion, has alleviated medical worker's work difficulty.
Description of drawings: accompanying drawing 1 is structural representation of the present invention.
Among the figure 1, body, 2, airtight frozen water pipe, 3, sleeve pipe, 4, the elastic force registration arm, 5, setscrew nut, 6, smooth oil jacket, 7, fixed handle.
The specific embodiment: comprise body 1, it is characterized in that outside body 1, being provided with airtight frozen water pipe 2, it is 1 centimetre sleeve pipe 3 that airtight frozen water pipe 2 outsides are provided with length, it is 1 centimetre and four symmetric elastic force registration arm 4 that sleeve pipe 3 two ends are provided with length, elastic force registration arm 4 directions with respect to sleeve pipe 3 radially outward, the horizontal level of sleeve pipe 3 stage casings and elastic force registration arm 4 is provided with setscrew nut 5, airtight frozen water pipe 2 leading portions and elastic force registration arm 4 surfaces are provided with smooth oil jacket 6, and airtight frozen water pipe 2 rear ends are provided with fixed handle 7.When carrying out thoracoscopic operation to patient, the position of adjusting sleeve pipe 3 is also fixing with setscrew nut 5, and body 1 is inserted the incision intercostal, rotation body 1, and elastic force registration arm 4 is stuck on the rib, and fixedly fixed handle 7; Avoid blood coagulation by airtight frozen water pipe 2; Avoid getting final product with the tissue adhesion by smooth oil jacket 6.
