Abstract
The invention discloses a multifunctional broken bolt thrombus taking device, which comprises an external plastic elastic sleeve, an internal rotating pipe and a rotating operation mechanism.
Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a multifunctional broken thrombus taking device.
Background
Cardiovascular and cerebrovascular blocks up, some adopt and dissolve the thrombus, some adopt methods such as thrombectomy to dredge the blood vessel and in time resume the blood supply for relevant tissue, thereby reduce death or disability incidence, get the thrombus and pass through operation under the development and operate, the thrombectomy instrument among the prior art scrapes off the thrombus on the blood vessel inner wall through the spring coil, the operating resistance is big, and be direct effort to the effort of thrombus, the spring coil can not be by oneself the adjustment shape when meetting the resistance yet, can be said hard to hard operation process, the comfort level is not high, and still cause the injury to the blood vessel inner wall easily, some wait to improve.
Disclosure of Invention
In order to solve the problems, the invention aims to provide a multifunctional broken thrombus taking device.
The technical scheme of the invention is as follows: the utility model provides a device is got to multi-functional bits of broken glass bolt, includes outside plastic elastic sleeve and inside rotating tube, rotatory operating device, characterized by:
the front end part of the rotary pipe extends out of the front part of the elastic sleeve, the front part of the rotary pipe is of a retractable expandable steel wire mesh structure, the foremost end of the steel wire mesh is a guide cap with an arc-shaped surface, an expansion control pull wire is fixedly connected inside the guide cap, and the expansion control pull wire is positioned inside the rotary pipe;
the rotary operating mechanism comprises a front frame plate and a rear frame plate, two sliding rods are connected between two ends of the front frame plate and the rear frame plate, mounting holes are formed in the middle of the front frame plate and the rear frame plate, a screw rod is mounted in the front mounting hole and the rear mounting hole through a bearing, a screw rod nut body is sleeved on the screw rod, and two ends of the screw rod nut body are sleeved on the sliding rods through sliding holes; the axis of the screw rod is provided with a hollow through hole,
the upper end of the screw rod is connected with the tail part of the rotary pipe into a whole, the upper surface of the front frame plate is connected with the tail part of the elastic sleeve into a whole, an expansion traction screw rod is arranged in a hollow through hole in the screw rod, the upper end of the expansion traction screw rod is connected with the tail part of the expansion control pull wire into a whole, and the lower end of the expansion traction screw rod extends out of the lower end of the screw rod and is provided with a butterfly-shaped operation nut.
Preferably, the lower end of the screw rod extends out of the rear frame plate, and the butterfly operating nut is not in contact with the rear frame plate.
Preferably, the expansion control pull wire is made of a guide wire.
Preferably, the steel wire mesh adopts a crossed rhombic woven structure.
The invention has the technical effects that:
according to the multifunctional broken thrombus removal device, thrombus on the inner wall of the blood vessel is removed by friction through rotation of the mesh-shaped expansion head, the expansion head is in a mesh shape, and can be compressed and deformed when encountering overlarge resistance, so that the inner wall of the blood vessel is not damaged, the diameter of the expansion head can be controlled through the relative position of the traction line and the rotating tube, and the flexibility is stronger.
