Description
Technical field
This utility model belongs to medical instruments field, relates in particular to a kind of implanted medical device conveyer device.
Background technology
In the disease treatment that chest aorta, abdominal aortic etc. are located and other surgical operations, use more and more inner cavity insulation technology.Inner cavity insulation technology generally adopts the apparatuses such as percutaneous intervening mode transfer gantry in blood vessel in patient body or in other body passages, does not need to cut patient thoracic cavity or abdominal cavity, and it has the advantages such as the little and operating time of wound is short, enjoys great popularity.Support is delivered in body internal channel, need to passes through special stent conveying device.As american documentation literature US6019778A discloses a kind of " self-expanding stent conveying equipment ", the inner and outer tubes and the elongated tubular that comprise coaxial setting, elongated tubular has oversheath, its have far-end and near-end polymeric outer layer, there is the polymer inner layer of far-end and near-end and the braiding enhancement layer between them.In oversheath, there is a tapered distal end flexibly.During use, the support matching and need conveying for placing in the end of inner and outer tubes, under the clamping of inner and outer tubes, support is delivered into blood vessel or other body passages, the position of support in human body is by XRF screen monitor, support arrives after destination locations, by operation conveyer device releasing bracket, completes the installation of support.This releasing operation need to be more careful technical ability, but due to some reasons, as the interference of dynamic blood flow to diseased region or narrow positions, the epitheca of the support of elastic dilatation is retracted gradually, capital affects the release precision of support, brings difficulty to the accurate release of support.
Summary of the invention
This utility model mainly solves the interference that original stent conveying device is subject to dynamic blood flow and rack elasticity expansionary force, is difficult to accomplish the accurate release of support, causes support location inaccurate, affects the technical problem that support discharges precision; A kind of implanted medical device conveyer device is provided, and it can avoid the interference of dynamic blood flow and rack elasticity expansionary force, and accurate positioning support installation site reaches more easily, the object of releasing bracket more accurately.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: this utility model comprises housing and is located at the sliding part in housing, long tube and gear, sliding part is located on long tube, one side of sliding part is provided with tooth bar, tooth bar and described gear engagement, the side of described housing is provided with a window, the wheel rim of described gear protrudes from outside described window, the front end of described sliding part is connected with the outer tube of clamping implanted medical device, the front end of described long tube is connected with the inner tube being enclosed within outer tube, the rear end of long tube is connected with long tube cover, long tube cover is inlaid in the rear end of described housing, on described sliding part, be also connected with quick toggle mechanism.Long tube cover can hold a seal wire, and the rear port of long tube cover is seal wire entrance.At first, sliding part is near the front end of housing, be subject to the clamping of outer tube and inner tube, under doctor's operation, in the human pipeline that support-moving is placed to needs, then handsetting gear, rack drives sliding part by engagement moves after slowly, rotatablely moving of gear changed into the rectilinear motion of sliding part, after sliding part, move, drive slow retrude one segment distance of outer tube, now support fully contacts with blood vessel wall, then stir after quick toggle mechanism makes support fast and move, thereby support has lost the compressing of outer tube to be discharged completely, complete the accurate location of support, easy to operate and control.
As preferably, the end face of described housing is provided with the strip spacing hole of axial setting, and described quick toggle mechanism is the handle of upwards holding up being connected on described sliding part, and described handle is stuck in described spacing hole and protrudes outside spacing hole.Stir handle, handle can move forward and backward in spacing hole, thereby drives sliding part to move forward and backward.Handsetting gear, sliding part moves after slowly, and support slowly discharges, and after general sliding part, moves after 3～8cm, and support has been close in the human body interior conduit that needs to place, then stirs backward fast handle, moves after making sliding part fast, and support obtains fast and discharges.Reach more easily, the object of releasing bracket more accurately, the installation of support is difficult for being interfered, location and the degree of accuracy discharging are high.Spacing hole both sides also can mark-on centimeter scale, the critical point that slowly discharges and discharge fast also can mark-on slowly and Fast Labeling, be convenient to control.
As preferably, the length of described tooth bar is 3～10cm, and the length of described housing is 12～31cm, and the length of described spacing hole is 8～22cm, and described gear is 2～8cm from the distance of the front end of described housing.The length of tooth bar and the installation site of gear have determined the distance of slow release, if slowly release distance is 5cm, tooth bar length is made 6cm, and the distance of the front end of gear shrinking away from theshell body is 5cm.Handsetting gear, makes the tooth bar 5cm that passes by, now again can not handsetting gear, and can only stir sliding part by handle, thereby from mechanical ceiling structure, determine the distance of slow release, further guarantee the reliability of operation and the degree of accuracy that support discharges.
As preferably, the tooth root width of single tooth on described tooth bar is 1～4 mm, and the crown distance of adjacent two teeth is 1～4mm.Change above-mentioned two parameters, the translational speed of sliding part in the time of can changing handsetting gear, while guaranteeing slowly to discharge sliding part after the speed of moving meet the requirement that support slowly discharges.
