Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to a guide piece suitable for a micro-tip pressure sensor.
Background
In minimally invasive surgery, surgical treatment using a surgical technique known as "minimally invasive surgery" enables a surgeon to reach a target anatomical region of a patient by inserting a long, thin instrument into an incision of short length, for example, on the order of one centimeter in the patient.
In the context of some procedures, the surgical instrument may be one or more or rigid cylindrical instruments (e.g. antennas, electrodes, cannulas) intended to be inserted into the patient to a certain depth to reach the target anatomical region, the structure of the treatment largely depending on their skills if the needle or thread is inserted manually by the operator at all while the procedure is being performed, it is difficult to achieve high precision, and the risk of medical errors due to lack of accuracy is high, possibly causing some harm to the patient.
At present, the first micro-tip pressure sensor in China is researched and developed, but the necessary surgical accessory support is lacked in the surgical experiment process, and some instruments cannot be purchased on the market to meet the experimental process; under the condition, I independently develops a guide piece for guiding the sensor wire, which can meet the requirement of a microtip pressure sensor experiment, and ensures that the pressure sensor wire can enter the blood vessel through the guide piece, thereby ensuring the smooth operation.
SUMMERY OF THE UTILITY MODEL
The utility model mainly aims to provide a guide piece suitable for a micro-tip pressure sensor, which is made of plastic materials, wherein the guide piece is designed to be semicircular conical, the tip part of a working end is very sharp, an inner circle guide groove is formed in the guide end, the sharp part of the working end is used for puncturing and picking a blood vessel or cutting a small opening of an arterial blood vessel by using a surgical scissors, and then the tip part of the working end of the practical guide piece is inserted into the small opening cut by the surgical scissors to enter the arterial blood vessel, so that a sensor probe can conveniently enter the blood vessel from the guide groove of the guide end.
In order to achieve the above object, the present invention provides a guide for a microtip pressure sensor, including a guide body, a handle, a guide portion with a guide groove; the upper end of the guide piece body is a handheld part; the lower end of the guide piece body is a guide part.
Preferably, the handheld part is provided with anti-skid lines.
Preferably, the guide portion is a tip of a semicircular cone shape.
Preferably, the guide portion forms an angle of 100 ° to 160 ° with the guide body.
Preferably, the guide groove on the guide portion is an inner circular guide groove.
Preferably, the guide groove on the guide portion has a size larger than a wire diameter of the sensor wire.
The beneficial effects of the utility model specifically comprise:
1) the device is suitable for the micro-tip pressure sensor experiment operation and the similar operation needing the intra-arterial intubation;
2) through designing the guide piece of a plastics material, the guide portion is the design of half circular cone, and the work end point portion is very sharp-pointed, and the guide end has an interior circle guide groove, crosses through the sharp-pointed department of work end and chooses the blood vessel or cuts a osculum with the operation earlier to artery blood vessel, then practical guide piece work end point portion inserts in the operation and cuts the osculum that cuts and enter into artery blood vessel, makes things convenient for the sensor probe to get into blood vessel from guide end guide groove.
