[0003] However, such measuring catheters (also referred to as "medical measuring catheters" sometimes) are usually in the shape of a circular tube. If the sensors for measuring physiological parameters are directly installed on the outer peripheral surface of the measuring catheters, since the sensors themselves have thickness, the The section height of the measuring duct behind the sensor is correspondingly increased
Since such a measuring catheter often needs to enter the stenotic lesion of a coronary vessel in the human body, directly placing the sensor on the outer peripheral surface of the measuring catheter will increase the cross-sectional height of the catheter, causing such a catheter to be likely to move when the blood vessel moves. Can create an occlusive effect within the blood vessel, introducing more measurement error
In addition, if the local size of the catheter is too large, it will increase the difficulty of entering the lesion area and affect the success rate of the operation

The invention provides a fixture for manufacturing a measurement catheter. The fixture for manufacturing the measurement catheter is characterized in that a first mandrel and a second mandrel are included; a first bearing portion is formed on the side surface of one end of the first mandrel, a second bearing portion is formed on the side surface of one end of the second mandrel, the first mandrel can be separated from the second mandrel, and one end of the first mandrel is connected with one end of the second mandrel in a butt-joint mode, so that the first bearing portion and the second bearing portion jointly form a concave portion. According to the fixture for manufacturing the measurement catheter, the first mandrel can be separated from the second mandrel, the first bearing portion of the first mandrel and the second bearing portion of the second mandrel jointly form the concave portion, therefore, the manufactured measurement catheter can be provided with a concave portion for carrying a sensor, and then the section height of the measurement catheter carrying the sensor can be decreased.
Description
technical field [0001] The invention relates to a jig for manufacturing a measuring catheter. Background technique [0002] For many vascular diseases such as coronary heart disease, it is usually necessary to measure some physiological parameters such as blood pressure, oxygen saturation, blood pH value, etc. in the lesion area during the diagnosis and treatment. At present, the methods adopted for the measurement of the above parameters include, for example, measuring catheters. Sensors for detecting the above-mentioned physiological parameters are arranged on the outer surface of the measuring catheter. Physicians and the like measure by positioning such a measuring catheter to lesion areas in the human body, such as stenotic lesions of blood vessels, so as to obtain required physiological parameters. [0003] However, such measuring catheters (also referred to as "medical measuring catheters" sometimes) are usually in the shape of a circular tube. If the sensors for me...
