Abstract

The invention belongs to the technical field of artificial assisted hearts, and particularly relates to a percutaneous guide line traction device of an artificial assisted heart. The technical problem to be solved is to invent the percutaneous guide line traction device of the artificial assisted heart, and the percutaneous guide line traction device facilitates operation of a physician, shortens the surgery process and solves the problem that a percutaneous guide line can not smoothly penetrates out of the human body in the surgery process of installing the artificial assisted heart. According to the adopted technical scheme, the percutaneous guide line traction device of the artificial assisted heart comprises a handle and a traction needle, wherein a shell is hollow and provided with an installing hole, a pin is arranged in the shell, a nut cap is arranged at the top end of the pin, a nut plug is arranged at the lower end of the pin, the pin is a cylinder which is thin at the two ends and thick in the middle, the end without the nut cap abuts against the upper end of the nut plug, and a spring is arranged at the position where the pin makes contact with the nut plug.

Description

The traction apparatus of human assistance heart percutaneous wire
Technical field
The invention belongs to human assistance heart technical field, be specifically related to the traction apparatus of a kind of human assistance heart percutaneous wire.
Background technology
Human assistance heart has the blood-pumping function of accessory heart left ventricle, is the machinery that maintains good systemic circulation state.Being connected wire and need to passing human body skin at the installation process middle pump body of human assistance heart and external controller, the traction apparatus of human assistance heart percutaneous wire is exactly the drafting tool using when human assistance heart percutaneous cable passes human body skin, traditional human assistance heart percutaneous wire traction apparatus is a kind of traction connector of carbon fiber compound core conducting wire, this apparatus structure is complicated, size is larger, is unsuitable for using in operation process.
Summary of the invention
Technical problem to be solved by this invention is, for above-mentioned deficiency, invent a kind of operation that facilitates surgical doctor, shorten the human assistance heart percutaneous wire traction apparatus of operation process, solve human assistance heart and install in operation process, percutaneous wire can not pass the problem of human body smoothly.
The technical solution adopted in the present invention is: the traction apparatus of a kind of human assistance heart percutaneous wire, comprises handle and pull needle, wherein, housing hollow, has an installing hole on body, pin is located at enclosure interior, the top of pin is provided with a nut, and the lower end of pin is provided with a screw plug.
A kind of human assistance heart percutaneous wire as above traction apparatus, wherein, sells for cylinder thick between the detail of two, withstands on the upper end of screw plug without nut one end, and spring is located at the contact position of pin and screw plug.
A kind of human assistance heart percutaneous wire as above traction apparatus, wherein, pull needle is made by 1Cr18Ni9Ti, and its two ends are identical two syringe needles, and adjacent needle point is provided with a draw-in groove, and the another side of draw-in groove is provided with screw thread.
The invention has the beneficial effects as follows:
1. the good pull needle of pliability, bendable folds the shape that adapts to body surface's skin, makes percutaneous wire pass more smoothly skin.
2. structure is small and exquisite, simple to operate, and the one hand of having realized traction apparatus grasps, and is suitable for using in operation, facilitates surgical doctor operation.
Accompanying drawing explanation
Fig. 1 is human assistance heart percutaneous wire traction apparatus overall diagram;
Fig. 2 is human assistance heart percutaneous wire traction apparatus handle schematic diagram;
Fig. 3 is pull needle structure chart;
In figure: 1. nut, 2. housing, 3. pin, 4. pull needle, 5. spring, 6. screw plug, 7. needle point, 8. draw-in groove, 9. screw thread.
The specific embodiment
Below in conjunction with accompanying drawing, to a kind of human assistance heart percutaneous wire provided by the invention, traction apparatus is introduced:
As Figure 1-3, the traction apparatus of a kind of human assistance heart percutaneous wire, comprises handle and pull needle 4, one end of pull needle 4 is fixed in the installing hole of handle, wherein, housing 2 hollows of handle, have an installing hole on the housing 2 of handle, enclosure interior is equipped with pin 3, pin 3 is cylinder thick between the detail of two, sells 3 top and is provided with a nut 1, sells 3 lower end and is provided with a screw plug 6, nut 1 one end withstands on the upper end of screw plug 6, and spring 5 is located at the contact position of pin 3 and screw plug 6; Pull needle 4 two ends are identical two syringe needles, and one end of adjacent needle point 7 has a draw-in groove 8, and the another side of draw-in groove 8 is provided with screw thread 9.
Screw thread 9 is used for being connected with the adapter on wire, and draw-in groove 8 and pin 3 coordinates to be realized being connected of pull needle and handle.Pull needle is a minute hand of being made by the good material of pliability, can bend to special shape to adapt to the different structure of human epidermal.
Pull needle adopts the good 1Cr18Ni9Ti of pliability to make, and bendable folds the shape that adapts to body surface's skin, and its screw connection structure can reliably be connected with conductor jointer, can take wire out of human body smoothly; The structure of handle assembly can realize one hand and grasp, pressing lower nut makes pin in lower end position, pull needle just can be inserted in the installing hole of handle smoothly like this, and loosen nut pin is replied supreme end under the effect of spring force, and the draw-in groove of pull needle is lived by pin card and realized and being reliably connected with handle.
The major function of this device is to be applied in human assistance heart installation operation process percutaneous wire to pass external use, and operating process is as follows:
1, the threaded portion of percutaneous wire electric connector and pull needle is connected and fixed;
2, pull needle not being connected to conductor wire end passes through human body skin from patient chest intracavity;
3, by handle with pass external pull needle tip portion and be connected and fixed;
4, hand-held handle pulls out pull needle, drives the percutaneous wire electric connector of the pull needle other end to spread out of together human body simultaneously.
