Abstract
The invention provides a sleeve traction wire threading device. Comprises a cylinder body, a cylinder tip, a cylinder tail and a traction line fixing part; the cylinder body of the device is provided with two grooves; the opening direction of the groove is opposite to the threading direction; the device is integrally cast, and the grooves are directly arranged on two sides of the cylindrical part of the cylinder body; the two sides of the cylinder body adopt different structures, the cylinder tip adopts a cone shape, and the tail end of the device adopts a circular closed bulge; according to the threading device provided by the invention, the traditional threading operation hole is replaced by the groove, the threading difficulty is reduced, and the threading efficiency is improved.
Description
Technical Field
The invention relates to the field of auxiliary threading instruments, in particular to a sleeve traction wire threading device.
Background
Stitching has been present in our daily lives since the beginning of the original society. Surgical needles, from needles used for sewing clothing to doctors for closing wounds, require a thread to be threaded through the needle hole of the needle before use. When the esophagus support operation, the doctor can pull out the support and hang on patient's face through the nostril by the pull wire, but when the pull wire passes through throat and nostril when the pull wire comes out from internal, the pull wire can press the nasal mucosa, can produce great friction to the nasal cavity, and the skin of nasal cavity mucosa department is thinner, and the friction of oppressing of regularity causes the inside damage of nasal cavity easily. In order to protect the nasal mucosa of a patient, a rubber soft sleeve is sleeved on the traction line passing through the nasal mucosa section, the traction line is soft and poor in stiffness, and the two traction lines need to pass through the rubber soft tube, so that the threading difficulty is caused due to the large operation difficulty of threading, and the threading efficiency is low.
In conclusion, how to effectively solve the problems of soft traction line and inconvenient threading caused by poor stiffness for doctors is an urgent need.
Disclosure of Invention
The invention aims to solve the defects in the prior art and provides a sleeve pull wire threading device.
In order to achieve the purpose, the invention adopts the following technical scheme:
a sleeve traction line threading device comprises a cylinder body, a cylinder tip and a cylinder tail, wherein the cylinder tip and the cylinder tail are respectively connected to two ends of the cylinder body; the barrel tip and the barrel tail end are also provided with traction wire fixing parts; the barrel body is a hard rod-shaped cylinder.
Preferably, the tip of the barrel is designed as a dome cone.
Preferably, the whole length of the barrel body is designed to be a hard rod-shaped cylinder of 16 cm.
Preferably, the diameter of the cylinder body is 3-4 mm.
Preferably, the barrel tip and the barrel tail end are provided with two grooves which do not penetrate through the barrel body; the groove is a traction wire fixing part.
Preferably, the groove is designed to be inclined, and the inclined direction is opposite to the threading direction.
Preferably, the cylinder tail adopts a circular arc design.
Compared with the prior art, the invention has the beneficial effects that: due to the design of the double grooves, the traction wire is more attached to the threading device, and the resistance of the threading device passing through the rubber hose can be greatly reduced; the conical dome is more in accordance with the design of hydrodynamics, so that the inconvenience in threading operation is reduced during threading; the hard rod-shaped design exceeding the length of the hose effectively avoids the problems of original soft nature and poor stiffness of the traction wire during threading, and the traction wire can achieve the set purpose through the specific device.
Drawings
FIG. 1 is a front view of a sleeve pull wire threading device;
wherein: 1. a barrel body; 2. a barrel tip; 3. barrel tail; 4. a traction wire fixing part; 41. a first groove; 42. A second groove.
Detailed Description
In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.
Referring to fig. 1, the present invention provides a threading device for a sleeve pulling wire; the device comprises a cylinder body 1, a cylinder tip 2 and a cylinder tail 3 which are respectively connected with two ends of the cylinder body; the ends of the cylinder tip 2 and the cylinder tail 3 are also provided with traction wire fixing parts 4; the cylinder body 1 is a hard rod-shaped cylinder.
Preferably, the barrel tip 2 is of a domed cone design.
Preferably, the whole length of the barrel 1 is designed to be a rigid rod-shaped cylinder of 16 cm.
Preferably, the diameter of the barrel body 1 is 3-4 mm.
Preferably, the barrel tip and the barrel tail end are provided with two grooves which do not penetrate through the barrel body; the groove is a traction wire fixing part.
Preferably, the groove is designed to be inclined, and the inclined direction is opposite to the threading direction.
Preferably, the cylinder tail adopts a circular arc design.
The using method comprises the following steps: when the esophagus support operation, when the doctor need pass the rubber protective sheath to the pull wire, earlier wind the round in the first recess 41 of pull wire fixed part 4 that the one end of pull wire is in, let the pull wire after first recess 41 internal fixation well positioned, pull the pull wire to the second recess 42 of pull wire fixed part 4 and wind the round again, need taut pull wire of winding on stack shell 1 at this time, then wear into in the rubber protective sheath with section of thick bamboo point 2, because the inner hole diameter of pull wire threading device's diameter ratio rubber protective sheath is little, and be hard rodlike, consequently, can not receive very big resistance when passing the rubber protective sheath, compare and only use the pull wire to pass rubber hose, the degree of difficulty of operation has been reduceed to a great extent, doctor's operation has been made things convenient for.
The present invention has been described in relation to the above embodiments, which are only exemplary of the implementation of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the invention. Rather, it is intended that all such modifications and variations be included within the spirit and scope of this invention.
