Description
Technical Field
The invention relates to the field of medical instruments, in particular to a special two-half type dilator for a visual peritoneal dialysis catheter.
Background
The peritoneal dialysis catheter is the most commonly used peritoneal dialysis catheter, comprises a straight tube and a curled tube, and consists of a catheter, a lead wire and a polyester sleeve, wherein a side hole is arranged at the insertion end of the catheter, and the peritoneal dialysis catheter is characterized in that two arms are arranged at the insertion end and are Y-shaped, and the included angle between the two arms is 40 degrees. Peritoneal dialysis catheter methods are broadly divided into surgical incision, laparoscopic, and percutaneous puncture methods, wherein the percutaneous puncture method is a puncture procedure without incision of the abdominal cavity, and actually it is more "operative" than "operation". The operation is not needed to enter an operating room, and an operating room, a treatment room or even a bedside can be operated, compared with the classical incision method, the technical survival rate is better, when the peritoneal dialysis catheter is punctured through the skin, a dilator is used, and a large number of reamers are available on the market at present.
In the authorization notice number: the chinese invention of CN104841059B, entitled "puncture guide capable of tearing off sheath", discloses a puncture guide capable of tearing off sheath, which comprises a sheath and a stylet nested in the sheath, and the whole is rod-shaped, and is characterized in that the two ends of the sheath are open, the rear end is expanded, and is composed of two sheath bodies with horn-shaped petals, grooves are arranged on the two symmetrical sides of the rod body along the length direction, tearing openings are arranged on the grooves, and a pair of buckles matched with each other are arranged at the symmetrical positions of the sheath bodies close to the rod body and close to the two sheath bodies; the tip of the needle core is a solid cone or a rhombohedron, and the rear end of the needle core is an expansion body matched with the sheath body of the sheath. The inner dacron sleeve is a disposable medical product, the selling price is about 2000, a great economic burden is added to a patient, the catheter can enter an abdominal cavity when in use, but the inner diameter of the inner dacron sleeve is larger than the inner diameter of the avulsion sheath, so the inner dacron sleeve can only be inserted to the opening of the avulsion sheath, when the avulsion sheath is torn, the inner dacron sleeve can only be pushed into the avulsion sheath with force, and the avulsion sheath can only be torn at the external or internal superficial position, so the inner dacron sleeve is difficult to push to the posterior sheath of the rectus abdominus muscle, and particularly for patients with obesity or deeper rectus abdominus muscle, the inner dacron sleeve is difficult to put above the posterior sheath of the rectus abdominus muscle or periton; and if some thin patients with the rectus abdominis with shallow back sheaths tear the avulsion sheath, the inner dacron sleeve is forcefully pushed towards the inside of the avulsion sheath, and the inner dacron sleeve is probably pushed into the abdominal cavity but not above the abdominal cavity.
In the authorization notice number: in the chinese invention "double-layer dilator special for peritoneal dialysis catheter" of CN207785567U, it discloses a "double-layer dilator special for peritoneal dialysis catheter", which is characterized in that: comprises a tearing sheath and a guide core, the tearing sheath comprises a first fixed tube (2), a round table tube (4) and a second fixed tube (6), one side of the first fixed tube (2) is connected with the round table tube (4), one side of the round table tube (4) is connected with the second fixed tube (6), the inner diameter of the second fixed tube (6) is larger than that of the first fixed tube (2), the round table tube (4) is of a round table structure with openings at the upper bottom and the lower bottom, a through hole is formed in the middle of the guide core, the guide core comprises a tip (1) and a fixed column (3), one side of the tip (1) is connected with the fixed column (3), a pressing plate (8) is arranged on the outer side of the second fixed tube (6), an inner sliding sheath (18) is sleeved on the fixed column (3), the inner sliding sheath (18) is of a tubular structure, the inner sliding sheath (18) is positioned inside the second fixed tube (6), and the inner sliding sheath (18) can slide on the fixed column (3), the inner layer sliding sheath (18) is positioned between the fixed column (3) and the second fixed tube (6), and one side of the inner layer sliding sheath (18) is provided with a vertical plate (12). Although the inner sliding sheath supports the inner dacron sleeve, the outer tearing sheath can only be torn in the superficial surface of the skin of a human body, the tearing sheath deep in the body is difficult to tear, and only can be pulled out of the body for tearing for one section, so that the inner sliding sheath and the inner dacron sleeve are invisibly taken out of the body, particularly for patients with obesity and deeper rectus abdominis, the inner dacron sleeve is difficult to put above the posterior sheath of the rectus abdominis or the peritoneum, and when the integral body is inserted into the body, the insertion depth is difficult to hold, the circular truncated cone tube is difficult to hold to reach the upper part of the posterior sheath of the rectus abdominis or the peritoneum, and even possibly enters the abdominal cavity through the peritoneum, so that the circular cone tube can accurately reach the upper part of the posterior sheath of the rectus abdominis or.
