Specific embodiment
Come with reference to the accompanying drawings and detailed description to be further elaborated the technical solution of the utility model.
As shown in Fig. 1, blood vessel of the present utility model strips off device to be included pull rope 1, is respectively arranged in the two ends of pull rope 1
Joint 2,2 ', dop 3 and lever 6.Dop 3 and lever 6 are detachable with the joint 2,2 ' at the two ends of pull rope 1 respectively
Ground connection.The side of place of lever 6 is rear in definition figure, and the side of place of dop 3 is front.As shown in figs. 1 and 4, joint 2,2 ' are
Cylindricality with inner chamber 20, the one end open of inner chamber 20, other end closing, pull rope 1 stretches into inner chamber 20 and fixes from openend
Wherein.Joint 2,2 ' becomes larger from its openend towards blind end diameter, forms conical outer surface.
As shown in Figures 2 to 4, dop 3 includes collet body 30, and the collet body 30 has the assembling of its rear and front end of insertion
Hole 31, is sequentially formed with from back to front first step 32, second step 33 on the inwall of pilot hole 31, this two steps will be assembled
Hole 31 is divided into three sections, and from front leading portion 31a, interlude 31b and back segment 31c are then defined as successively, and wherein interlude 31b's is interior
Wall has and the identical taper of joint 2, and tight fit can be formed therebetween.Leading portion 31a's is straight with diameter greater than interlude 31b
Footpath and the external diameter of joint 2, between the inwall of the leading portion 31a of pilot hole 31 and the outer peripheral face of joint 2 gap 4 is formed with, between being somebody's turn to do
Gap 4 plays a part of to clamp blood vessel so as to realize ligation automatically.
When using, the rear end part of the joint 2 of the leading section of pull rope 1 is arranged in pilot hole 31, and its rear end and first
Step 32 offsets clamping and can not be moved rearwards by, meanwhile, the tool of the conical outer surface of joint 2 and the interlude 31b of pilot hole 31
Coordinate clamping between tapered inwall, realize being reliably connected for joint 2 and dop 3.Power thrusts during due to using be to
Pulling traction rope 1 afterwards, therefore, the cooperation between joint 2 and dop 3 very firmly, will not take out de- situation all the time.Meanwhile,
During joint 2 is connected with dop 3, the gap 4 between joint 2 and dop 3 can clamp blood vessel 7 and realize ligation automatically,
As shown in Figure 6.
Further, collet body 30 is provided with along its length the open slot 34 connected with pilot hole 31, is easy to lead
Messenger 1 passes through and enters in pilot hole 31, raised 5 is formed with the side wall of open slot 34, it is ensured that use in use
During power pulling traction rope 1, pull rope 1 will not skid off pilot hole 31 from open slot 34.
Further, the front end of collet body 30 is formed with depression 35, and being easy to when necessary can easily clamping chuck 3.
When in use, doctor inserts the joint 2 of pull rope 1 and its front end in great saphenous vein to the utility model, drive in the wrong direction into
Enter main venous trunk, and from being passed by resistance part wound, now blood vessel 7 is enclosed within pull rope 1 and joint 2, will first be cased with leading for blood vessel 7
Messenger 1 is entered in pilot hole 31 by open slot 34, then lever 6 is fixed on the joint 2 ' of the rear end of pull rope 1.With
Power pulls back pull rope 1, and now joint 2 is entered in the pilot hole 31 of collet body 30 under the active force of pull rope 1, until
Its rear end arrives to and moved after can not continuing on first step 31, that is, complete the self-locking of joint 2 and collet body 30.Fig. 6 is seen, in joint
2 with the auto-lock process of collet body 30 in, the blood vessel 7 outside joint 2 is clamped by gap 4, realizes ligation.Now, continue firmly to lead
Dragline messenger 1 can by blood vessel 7 strip off device with blood vessel together with extract out, you can complete great saphenous vein and take out stripping.
To sum up, using the utility model, operation is very easy, can save the operation of the ligation blood vessel of doctor, avoids operation
Method fixes blood vessel, instead of the method that blood vessel is fixed in traditional operation, it is possible to increase operating efficiency, improves security performance, contracting
Short operating time, mitigates Principle of Pain, and blood vessel of the present utility model strips off device and its dop simple structure, operation side
Just, convenient for production, low cost, with good potential applicability in clinical practice.
The utility model is described in detail above, its object is to make the personage's energy for being familiar with this art much of that
Solve content of the present utility model and be carried out, protection domain of the present utility model, and the utility model can not be limited with this
The above embodiments, all equivalence changes made according to Spirit Essence of the present utility model or modification are not limited to, all should be covered
Within protection domain of the present utility model.
