Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, relate in particular to a kind of adjustable artificial mechanical valve prosthesis's dilator.
Background technology
Along with the development of cardiac operation technology, Anesthesia Department, Intensive Care Therapy, increasing patient has accepted Cardiac valve replacement, in traditional mechanical heart valve replacement, valve is inserted in process, the exposure of valve below is often more difficult, in the past only by the open valve of single tiny stub, visual area exposes unclear, often can cause folding, the card lobe of lobe undertissue, pad, cause again removing the valve of finishing changing, and in art, good exposure is significant for successfully changing lobe.
Summary of the invention
Technical problem to be solved by this invention is: a kind of adjustable artificial mechanical valve prosthesis's dilator is provided.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: adjustable artificial mechanical valve prosthesis's dilator, comprise: titanium alloy tube, the handle being connected with titanium alloy tube one end and be set in the silica gel tube on the titanium alloy tube other end, on the titanium alloy tube between described silica gel tube and handle, be provided with plastics adjustment seat, in plastics adjustment seat, be provided with chute, in described chute, be provided with the rotating shaft cooperatively interacting with it, in described rotating shaft, be provided with gear, described gear cooperatively interacts with the tooth bar being fixedly installed on titanium alloy tube, outside described plastics adjustment seat, one end of rotating shaft is provided with knob and limited block, in the plastics adjustment seat of described chute both sides, be respectively arranged with the stopper slot cooperatively interacting with limited block, be provided with in inside, described plastics adjustment seat one end the stop collar cooperatively interacting with silica gel tube one end, the other end of silica gel tube and one end of described titanium alloy tube fix, on the other end of silica gel tube, be provided with opening, on the silica gel tube of described opening both sides, be respectively arranged with on two folding opening under folding opening and two.
Advantage of the present invention is: above-mentioned adjustable artificial mechanical valve prosthesis's dilator, simple to operate, safe and reliable, can carry out as required controllable type adjusting obviously to expose the size of valve orifice, structure under lobe is had to good exposure, can improve the safety of artificial valve replacement in operation, significant to shortening operating time.

In figure: 1, titanium alloy tube, 2, handle, 3, silica gel tube, 4, plastics adjustment seat, 5, chute, 6, rotating shaft, 7, gear, 8, tooth bar, 9, knob, 10, limited block, 11, stopper slot, 12, stop collar, 13, opening, 14, upper folding opening, 15, lower folding opening.
The specific embodiment
Describe in detail particular content of the present invention below in conjunction with the drawings and specific embodiments.
As Fig. 1, Fig. 2, shown in Fig. 3, adjustable artificial mechanical valve prosthesis's dilator, comprise: titanium alloy tube 1, the handle 2 being connected with titanium alloy tube 1 one end and be set in the silica gel tube 3 on titanium alloy tube 1 other end, on the titanium alloy tube 1 between described silica gel tube 3 and handle 2, be provided with plastics adjustment seat 4, in plastics adjustment seat 4, be provided with chute 5, in described chute 5, be provided with the rotating shaft 6 cooperatively interacting with it, in described rotating shaft 6, be provided with gear 7, described gear 7 cooperatively interacts with the tooth bar 8 being fixedly installed on titanium alloy tube 1, be provided with knob 9 and limited block 10 in one end of described plastics adjustment seat 4 outside rotating shafts 6, in the plastics adjustment seat 4 of described chute 5 both sides, be respectively arranged with the stopper slot 11 cooperatively interacting with limited block 10, be provided with in described plastics adjustment seat 4 inside, one end the stop collar 12 cooperatively interacting with silica gel tube 3 one end, one end of the other end of silica gel tube 3 and described titanium alloy tube 1 fixes, on the other end of silica gel tube 3, be provided with opening 13, on the silica gel tube 3 of described opening 13 both sides, be respectively arranged with on two folding opening 15 under folding opening 14 and two.
When above-mentioned adjustable artificial mechanical valve prosthesis's dilator is opened, turning knob 9 forward, described knob 9 drives rotating shaft 6 to rotate, rotating shaft 6 driven gears 7 rotate, because gear 7 and tooth bar 8 cooperatively interact, thereby band carry-over bar 8 does rectilinear motion backward, tooth bar 8 drives titanium alloy tube 1 to move backward, because one end and the stop collar 12 of silica gel tube 3 offset, one end of the other end of silica gel tube 3 and described titanium alloy tube 1 fixes, thereby make silica gel tube 3 be subject to thrust forward, now opening 13 under the effect of thrust by folding opening 14 and lower folding opening 15 open, while opening card completely, being arranged on limited block 10 in rotating shaft 6 encounters the stopper slot 11 of plastics adjustment seat 4 front ends and carries out spacing.
When above-mentioned adjustable artificial mechanical valve prosthesis's dilator is closed, knob 9 rotates backward, described knob 9 drives rotating shaft 6 to rotate, rotating shaft 6 driven gears 7 rotate, because gear 7 and tooth bar 8 cooperatively interact, thereby band carry-over bar 8 does forward rectilinear motion, tooth bar 8 drives titanium alloy tube 1 to travel forward, because opening 13 has thrust backward to silica gel tube 3 under the effect of upper folding opening 14 and lower folding opening 15, thereby make silica gel tube 3 keep offseting with stop collar 12 always, be arranged on limited block 10 in rotating shaft 6 and encounter the stopper slot 11 of plastics adjustment seat 4 rear ends and carry out spacing.
Above-mentioned adjustable artificial mechanical valve prosthesis's dilator, simple to operate, safe and reliable, can carry out as required controllable type adjusting obviously to expose the size of valve orifice, structure under lobe is had to good exposure, can improve the safety of artificial valve replacement in operation, significant to shortening operating time.
