Abstract
The invention discloses a self-locking clamping head device of a great saphenous vein stripping catheter. The device comprises a clamping head nut and a self-locking screw, a jamming position is arranged at the top of the self-locking screw, a self-locking thread is arranged in the middle of the outer side of the self-locking screw, a taper guiding piece is arranged at the lower end of the self-locking screw, and a longitudinal assembling groove is formed in the inner side of the self-locking screw; a longitudinal inner thread matched with the self-locking screw is arranged in the middle of the inner side of the clamping head nut, a taper groove is formed in the lower end of the inner side of the clamping head nut, a round hole concentric with the longitudinal assembling groove of the self-locking screw is formed in the bottom of the clamping head nut, and the round hole is communicated with the taper groove. The self-locking clamping head device is simple in structure, a blood vessel and a stripping head are fixed with an arc clamping head nut body and the self-locking screw, operation threads used in traditional operations are substituted for fixing the blood vessel and the stripping head, the working efficiency can be effectively improved, operation time can be effectively shortened, and patient pains can be alleviated.
Description
Technical field
The present invention relates to a kind of small medical auxiliary device, be specifically related to the self-locking card head unit that a kind of great saphenous vein strips off conduit.
Background technology
At present, in great saphenous varicose vein treatment clinical course, conventional operative therapy is the vein ligation of varicose and thoroughly takes out stripping, traditional modus operandi is from thigh root to medial leg portion many places otch to excise cirso-, and this method exists that wound is large, patient is compared with painful, that the hospital stays long, paralysed trace is many, cosmetic result is poor shortcoming.Disposable vein sold on the market strips off device at present, the anti-self-locking design that its dop is not special, so in use complex operation, and it is low once to strip off success rate, thus stripping off blood vessel by the phenomenon pumped off, doctor needs again to do otch and strip off pumping off position, easily causes surrounding tissue and nerve injury, add the misery of patient, extend operating time.
Therefore, development precise and high efficiency vein chuck device has important practical significance and good application prospect.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of structure great saphenous vein that is simple, that can fix blood vessel and stripping head fast and takes out and shell self-locking card head unit
To achieve the above object of the invention, the technical solution used in the present invention is: a kind of great saphenous vein strips off the self-locking card head unit of conduit, comprise dop nut and Self-locking screw, described Self-locking screw top is provided with jam position, middle part, outside is provided with self-locking thread, lower end is provided with tapering prerotation vane, and inner side is provided with longitudinal fitting recess; Inside described dop nut, middle part is provided with the longitudinal inner thread matched with Self-locking screw, and inside lower end is provided with taper groove, and bottom is provided with the circular hole concentric with longitudinal fitting recess of Self-locking screw, and described circular hole communicates with taper groove.
In technique scheme, described dop nut outer surface and Self-locking screw upper end are round and smooth design, do not have sharp keen edge.
In technique scheme, described dop nut is that bullet-shaped is streamlined, taper, spherical or cylindrical.
In technique scheme, the clamping part of described longitudinal fitting recess is symmetrical plane, grooved, U-shaped or V-type.
Further technical scheme, described dop nut and Self-locking screw are movably attached to pull rope joint.
The material of self-locking card head unit of the present invention can be that rustless steel, nylon, polypropylene, polyethylene, styrene one acrylonitrile one butadiene block copolymer, poly-carbonic acid are cruel, acrylic or polyethylene terephthalate.
Because technique scheme is used, the present invention compared with prior art has following advantages:
1. structure of the present invention is simple, fix blood vessel by circular arc dop nut body and Self-locking screw and strip off head, instead of in traditional operation and fix blood vessel with surgical thread and strip off head, and can effectively increase work efficiency, effectively can reduce operating time, alleviate patient's misery.
2. the present invention is by the design of self-locking dop, makes pull rope pass through blood vessel, increases device and passes through performance, farthest alleviate tunica intima and the damage of stripping off blood vessel perienchyma, and can effectively prevent from stripping off coming off of dop in vascular process.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
Embodiment one: see shown in Fig. 1 to 4, a kind of great saphenous vein strips off the self-locking card head unit of conduit, comprise dop nut 2 and Self-locking screw 1, described Self-locking screw top is provided with jam position, middle part, outside is provided with self-locking thread 4, lower end is provided with tapering prerotation vane 5, and inner side is provided with longitudinal fitting recess 3; Inside described dop nut, middle part is provided with the longitudinal inner thread 7 matched with Self-locking screw, and inside lower end is provided with taper groove 8, and bottom is provided with the circular hole 6 concentric with longitudinal fitting recess of Self-locking screw, and described circular hole communicates with taper groove.
Described dop nut outer surface and Self-locking screw upper end are round and smooth design, do not have sharp keen edge.
Dop nut of the present invention has different size, is the dop nut of 5 ~ 20mm, can selects according to patient's blood vessel diameter by diameter of section.
Shown in Figure 5, the joint 9 of hawser 10 in use, inserts in great saphenous vein by the present invention, drives in the wrong direction and enters main venous trunk, and pass from by resistance part wound.Self-locking screw being arranged on cover has on the hawser of blood vessel, and dop nut is arranged on Self-locking screw, vein blood vessel and self-locking card head unit are fixed, the other end again handle 11 being fixed on hawser coordinates with joint, firmly extract hawser out blood vessel is extracted out together with self-locking card head unit, auxiliary great saphenous vein can be completed and take out stripping.
