Description

Catheter introduction instrument
Technical Field
The invention belongs to a medical instrument for introducing a ureter (catheter), in particular relates to a medical instrument used for introducing the ureter aiming at a male suffering from urethral stricture, and particularly relates to a catheter introducing instrument.
Background
Urethral stricture is one of common diseases of urology surgery, and is mostly seen in men, the clinical manifestations of patients have diversity, so the treatment methods also have diversity, patients mainly show symptoms such as dysuria, urinary retention, urinary tract infection, bladder calculus, and the like, severe patients even have renal function damage, male infertility and sexual dysfunction, the life quality of patients is seriously influenced, and even the lives of patients are endangered.
For patients with dysuria, catheterization is generally performed before the operation, and for patients with urethral stricture, a traditional catheter cannot pass through the narrow area of the male urethra. The conventional operation is to adopt a metal guide wire to support and guide a silicone tube into a bladder, but in the operation process, the guide wire is relatively soft and sharp, so that the guide wire is often punctured from a catheter when passing through a narrow area, the urethra is damaged, and serious complications such as heavy bleeding, infection, rectal fistula and the like are formed. The prior art also has some structures which are complicated in structure and guide the urinary catheter. The catheter introducing apparatus in the prior art has poor effect of introducing the catheter and is easy to cause harm to patients.
The invention aims to provide a catheter introducing instrument aiming at the problems that the catheter introducing instrument in the prior art can not well introduce a catheter, and the urethra of a patient can not be well protected in the introducing process.

Further, a clamp structure is arranged at the horn-shaped structure or the T-shaped structure. The clip is used for being fixed in horn-shaped structure or T shape structure department with the silica gel catheter, prevents the relative movement of silica gel catheter and stereoplasm hollow tube position to can effectively prevent the catheter front end retraction, effectively prevent the damage that the stereoplasm hollow tube caused urethra tissue.
Furthermore, the size of the opening of the longitudinal through opening accounts for 1/4-1/3 of the circumference of the whole hard hollow tube. The silica gel catheter can be effectively put into and removed out of the hard hollow tube by the proper opening size.
Further, the preferable ratio of the size of the opening of the longitudinal through opening to the entire circumference of the hard hollow tube is 1/3.
Furthermore, the diameter of the hard hollow tube is slightly larger than the outer diameter of the silica gel catheter. The arrangement can further ensure the relative stability of the position when the silica gel catheter is combined with the hard hollow tube, and prevent relative movement.
Furthermore, the handle is flat, and is convenient to grasp and operate during operation.
Furthermore, the material of the hard hollow tube can be any hard material, such as hard metal material and hard plastic material, preferably medical stainless steel material.
Further, the catheter introducing instrument is provided with different pipe diameter models. Different models of settings can meet the needs of different patients.
Further, the catheter introduction instrument is provided with relevant models F12, F14, F16, F18, F20, F22, F24 and the like.
Further, the sterilized catheter introducer device is arranged in a packaging bag with a proper size.
Further, the hard hollow tube and the silica gel catheter of the catheter introducing instrument in the package are of a sleeved structure, and the clamp is independently arranged in the package bag.
Further, the catheter introducer device is a disposable medical device.
When the silica gel catheter is used, the introducing instrument is taken out of the packaging bag, the relative positions of the hard hollow tube and the silica gel catheter are slightly adjusted, the front end of the silica gel catheter extends out of the hard hollow tube, and the clamp is clamped at the horn-shaped structure or the T-shaped structure to prevent the relative movement of the positions of the hard hollow tube and the silica gel catheter; after the device is set, the introducing device slowly passes through the urethra of a patient suffering from urethral stricture, and slowly passes through the physiological bending part of the male urethra and the stricture urethra by utilizing the bending part, and the insertion is stopped after the silica gel urinary catheter reaches the bladder; then the air bag or the water bag structure is inflated or filled with water through an inflating or water filling device, so that the silica gel catheter is fixed in the bladder; the hard hollow tube is slowly withdrawn afterwards, the horn mouth is arranged to facilitate the withdrawal of the hard silicone tube, the introduction of the catheter is completed, and the urine storage bag is connected with the tail end of the catheter afterwards.
Compared with the prior art, the catheter introducing instrument is integrally formed, has higher strength, does not have mechanical failure, and is simpler and more practical to operate; the arrangement of the bending part can lead the catheter to smoothly pass through the physiological bending of the urethra; the positions of the hard hollow tube and the silica gel catheter are set to ensure that the catheter can smoothly pass through a narrow area without damaging the urethra; the arrangement of the longitudinal through opening and the horn-shaped structure or the T-shaped structure can ensure that the hard hollow tube can be effectively withdrawn after the catheter is introduced, and the arrangement of the horn-shaped structure or the T-shaped structure and the clamp structure can ensure the stability of the position of the catheter and the hard hollow tube when the catheter enters. In conclusion, this structure can achieve a good effect of introducing the catheter into the bladder of a patient with a urethral stricture.
