Description

The traction apparatus of human assistance heart percutaneous leads
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 leads.
Background technology
Human assistance heart has the blood-pumping function of accessory heart left ventricle, is the machinery maintaining good systemic circulation state.Need through human body skin at the installation process middle pump body of human assistance heart and the connection wire of external controller, the traction apparatus of human assistance heart percutaneous leads is exactly through the drafting tool used during human body skin at human assistance heart percutaneous cable, traditional human assistance heart percutaneous leads traction apparatus is a kind of traction connector of carbon fiber compound core conducting wire, this apparatus structure is complicated, size is comparatively large, 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 facilitating surgical doctor, shorten the human assistance heart percutaneous leads traction apparatus of operation process, solve human assistance heart to install in operation process, percutaneous leads 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 leads, comprises handle and pull needle, wherein, housing hollow, body has an installing hole, and 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 leads as above traction apparatus, wherein, sell for cylinder thick between the detail of two, withstand on the upper end of screw plug without nut one end, the contact position of pin and screw plug is located at by spring.
A kind of human assistance heart percutaneous leads as above traction apparatus, wherein, pull needle is made up of 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 adapting to body surface's skin, makes percutaneous leads pass skin more smoothly.
2. compact structure, simple to operate, the one hand achieving traction apparatus grasps, and is suitable for using in operation, facilitates surgical doctor to operate.
Accompanying drawing explanation

Fig. 2 is human assistance heart percutaneous leads traction apparatus handle schematic diagram;
Fig. 3 is pull needle structure chart;
In figure: 1. nut, 2. housing, 3. sell, 4. pull needle, 5. spring, 6. screw plug, 7. needle point, 8. draw-in groove, 9. screw thread.
Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of human assistance heart percutaneous leads provided by the invention traction apparatus is introduced:
As Figure 1-3, the traction apparatus of a kind of human assistance heart percutaneous leads, comprises handle and pull needle 4, one end of pull needle 4 is fixed in the installing hole of handle, wherein, housing 2 hollow of handle, the housing 2 of handle has an installing hole, enclosure interior is equipped with pin 3, pin 3 is cylinder thick between the detail of two, and the top of pin 3 is provided with a nut 1, and the lower end of pin 3 is provided with a screw plug 6, nut 1 one end withstands on the upper end of screw plug 6, and the contact position of pin 3 and screw plug 6 is located at by spring 5; 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 coordinates with pin 3 connection realizing pull needle and handle.Pull needle is a minute hand be made up of 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 adapting to body surface's skin, and its screw connection structure reliably can 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 be in lower end position, such pull needle just can be inserted in the installing hole of handle smoothly, and loosen nut pin returns back to upper end under spring force, and the draw-in groove of pull needle is lived by pin card and realizes reliably being connected with handle.
The major function of this device is applied in human assistance heart installation operation process percutaneous leads to pass external use, and operating process is as follows:
1, the threaded portion of percutaneous leads electric connector and pull needle is connected and fixed;
2, pull needle is not connected conductor wire end to pass through human body skin in chest;
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 leads electric connector of the pull needle other end to spread out of human body together simultaneously.
