Description

A hollow plain tube flexible medical thread

technical field

The utility model relates to a soft medical thread of a hollow plain corrugated tube, which belongs to the technical field of medical equipment components.

Background technique

With the rapid development of modern medical technology, the matching medical equipment and medical equipment industry is also developing rapidly. Among them, optical endoscopes, laser knives, etc. are often used in surgical operations, which need to penetrate into the internal organs of the human body, and at the same time supplemented by a series of monitoring equipment, such as monitoring heartbeat, blood pressure, etc.; Each part is independent, takes up a lot of space, is inconvenient for surgeons to operate, and even affects the accuracy of surgical operations.

Contents of the invention

(1) Technical problems to be solved

In order to solve the above problems, the utility model proposes a medical instrument for comprehensive surgery, a hollow plain tube soft medical thread that ensures surgical precision.

(2) Technical solutions

The soft medical thread with hollow plain tube of the utility model, the soft medical thread with hollow plain tube, comprises a hollow plain tube; and an aluminum foil Mylar tape wrapped around the hollow plain tube; Inner tin-plated annealed annealed copper wire braided shielding mesh; and inner cotton paper tape around the wrapping and inner tinned annealed annealed soft copper wire braided shielding mesh; and insulating cores of 6 ultra-fine conductors arranged at intervals on the outer periphery of the inner cotton paper tape wire; and the outer cotton paper tape around the wrapping and insulated core wire; and the white medical grade TPU inner quilt around the extruded and outer cotton paper tape; and the outer tinned annealed annealed soft copper set outside the white medical grade TPU inner jacket Wire braided shielding mesh; and a medical grade PUR sheath set outside the outer tinned annealed annealed copper wire braided shielding mesh.

Further, the specification of the insulated core wire is 32AWG.

Further, the insulated core wires are made by setting and positioning the mold through 100% untwisted wires, arranging the surfaces of the paper tape layers according to the average equidistant, and controlling the mutual misalignment tolerance within 0.1 mm.

Further, the six insulated core wires are identified by different colors.

Further, the weaving density of the outer tinned annealed annealed copper wire braided shielding net is above 98%.

(3) Beneficial effects

Compared with the prior art, the flexible medical wire of the hollow plain tube of the utility model, when in use, the inside of the hollow tube will pass through the optical endoscope, laser knife, etc., and the 6 insulating core wires in the middle layer of the wire are used to transmit the operation Monitoring signals, including patient's heartbeat, blood pressure, etc.; both ends of the wire are connected to each unit of the medical device with special terminals, and one end of the optical endoscope, laser knife, etc. is connected to the operating unit, and the surgeon can directly operate it.

Description of drawings

Fig. 1 is a schematic diagram of the overall structure of the utility model.

Detailed ways

The flexible medical line with hollow plain corrugated tube as shown in Figure 1 includes a hollow plain corrugated tube 1; its biggest feature is that it is soft and can be bent in any direction; and an aluminum foil Mylar tape 2 wrapped around the hollow plain corrugated tube 1 Play the role of shielding the outside world (the inner direction of the empty pipe) from electromagnetic interference and isolating and protecting the outer layer structure of the electric wire; The plain tube prevents expansion and contraction, and at the same time compensates and strengthens the electromagnetic interference in the inner direction of the empty tube; and the inner cotton paper tape 4 on the periphery of the wrapping and inner tinned annealed soft copper wire braided shielding net 3; used for isolation and protection Adjacent outer layer insulated core wires; and the insulated core wires 5 of 6 superfine conductors arranged at intervals on the periphery of the inner tissue paper tape 4; and the outer tissue paper tape 6 wrapped around the periphery of the insulated core wire 5; 6 insulated core wires are tightly wrapped and fixed on the surface of the empty tube; and the white medical-grade TPU inner quilt 7 around the extruded and outer tissue paper tape 6; can well support and protect the internal structure; and is set on a white medical-grade The outer tinned annealed annealed soft copper wire braided shielding net 8 on the outer side of the TPU inner quilt 7; plays the role of shielding the electromagnetic interference from the outside world (outside the wire), preventing external strong electric fields, strong magnetic fields, and strong radiation from generating surgical monitoring signals transmitted inside the wires Interference, to ensure the accuracy of the instrument; and the medical-grade PUR sheath 9 arranged outside the outer tinned annealed soft copper wire braided shielding net 8 .

Wherein, the specification of the insulated core wire 5 is 32AWG; the insulated core wire 5 is set and positioned by a 100% untwisted wire, and the surface of the paper tape layer is arranged at an average equidistant distance, and the mutual misalignment tolerance is controlled within 0.1mm. The six insulated core wires 5 are identified by different colors; the weaving density of the outer tinned annealed annealed copper wire braided shielding net 8 is more than 98%.

The above-mentioned embodiments are only descriptions of preferred implementations of the present utility model, and are not intended to limit the concept and scope of the present utility model. Under the premise of not departing from the design concept of the utility model, various modifications and improvements made by ordinary persons in the art to the technical solution of the utility model should fall into the protection scope of the utility model, and the technology claimed by the utility model The contents are all described in the claims.
