Description

Double-soft-head guide wire

Technical Field

The utility model relates to a medical seal wire technical field specifically is a two soft head seal wires.

Background

The ureteral stent is needed to be placed when patients with advanced gynecological tumor or rectal tumor involve the trigone area of the bladder or are pressed to cause ureteral stenosis, the existing mode of placing the ureteral stent in the ureteral stent is limited to that only one end of a traditional guide wire is a soft end, so that during operation, most of the patients are used for placing the ureteral stent by cutting open the ureter, when in specific operation, the soft end is firstly placed into the bladder after being punctured through the ureter, the soft end of the guide wire is found out through the urethra and pulled out to enable the hard end to be positioned in the ureter, but the guide wire cannot be placed into the renal pelvis through the hard end (the guide wire at the hard end is sharp, the ureter is easy to cause ureteral injury in the ascending process of the ureter), so the guide wire needs to be taken out, the soft end is replaced to be placed into the guide wire through the ureteral orifice again, and the operation can cause ureteral stenosis possibly that the ureter can not be placed because the ureteral loss can be caused, and causes the operation to be time-consuming and risky.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a two soft first seal wires to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model adopts the following technical scheme:

a double-soft-head guide wire comprises a guide wire body, wherein the guide wire body is composed of a first guide wire section and soft head ends, the soft head ends are located at two ends of the first guide wire section and are smaller than the first guide wire section in diameter, a spiral guide core wire is arranged inside any one of the soft head ends, the soft head end and the first guide wire section are integrally formed through an arc transition portion, one end, far away from the first guide wire section, of any one of the soft head ends is conical, a coloring mark ring is sleeved on the outer surface of any one of the soft head ends, and a concave portion is arranged on the outer annular surface of each of the two coloring mark rings.

Preferably, an inner core wire parallel to the first guide wire section is arranged in the middle of the inside of the first guide wire section in a penetrating mode, a coating layer is wrapped on the outer surface of the guide wire body, and the coating layer is made of polytetrafluoroethylene.
