Description

General type supersound guide bracket of card formula

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to general type supersound guide bracket of card formula.

Background

Ultrasound-guided interventional procedures have become a routine means for clinical diagnosis and treatment, and are widely applicable to interventional diagnosis, such as diagnostic needle biopsy under ultrasound guidance, various diagnostic aspirations, PICC under ultrasound guidance, various catheterization, tumor ablation, stent implantation and the like.

At present, two means are usually used for interventional operation under ultrasonic guidance, one is that a bare-handed interventional operation is directly carried out without an ultrasonic guide support, the advantages are that the operation steps are less, a specific puncture frame is not needed to be matched, the interventional operation can be carried out under various probes, the puncture direction can be automatically controlled, the defects are that the positioning is not accurate enough, the operation manipulation of an operator is required to be skilled, a skilled operator needs longer time and enough cases for training, the puncture implementation process is easy to fail, a doctor is not allowed to fail in the interventional process in the medical practice, and the pain of a patient is aggravated by repeated puncture; in addition, in medical training, the efficiency of free-hand training without an ultrasound guide stent is low, and the effect of intervention is excessively dependent on the proficiency of doctors, which is contrary to the development trend of refinement and standardization of minimally invasive diagnostic treatment.

Therefore, in both medical practice and medical training, a precise ultrasound guide bracket matched with the puncture needle is needed, which is the second type of ultrasound-guided intervention currently popularized in the medical field. However, in order to adapt to the diagnosis of different visceral diseases, the present medical diagnostic ultrasound apparatuses develop various ultrasound probes of the same type, but the frequency, appearance and scanning mode of the probes are different, the various ultrasound apparatuses in the ultrasound department of hospitals are not uniform, the shapes of the probes are different, if the intervention under ultrasound guidance is needed, each probe must be equipped with a guide bracket suitable for the specific shape, and when the ultrasound apparatuses are purchased, hospitals do not purchase corresponding guide brackets for each probe at the same time, thus restricting the development of ultrasound intervention and the training of interventional physicians; in addition, some ultrasound equipment manufacturers often equip various expensive ultrasound guide stents for the purpose of maximizing profit of medical equipment, and the equipped ultrasound guide stents cannot be compatible with ultrasound probes of different models of the same manufacturer or other manufacturers, thereby greatly increasing the medical cost of hospitals and finally being transferred to patients.

In addition, different medical scenarios also place different requirements on ultrasound guided stents. For example, in a large hospital with a large number of surgeries, a guide bracket made of glass fiber reinforced plastic or medical grade stainless steel is adopted, and the average cost is effectively controlled because the disinfection quality can be ensured and the relatively high manufacturing cost can be leveled out by the higher utilization rate. However, in medical environments where the disinfection apparatus is relatively backward and the number of procedures is low, such as in battlefields or remote areas, a disposable ultrasound guide stent that does not require disinfection and is low in cost is more popular, and such a disposable ultrasound guide stent is expected to be comparable in use effect to a reusable medical-grade stainless steel ultrasound guide stent, and further, the patient himself/herself also desires to be able to select between the two.

It should be noted that in a medical scenario where a plurality of electromagnetic medical devices are used cooperatively, a disposable ultrasound guide stent made of plastic is more likely to be adopted, considering that a metal material may generate electromagnetic interference to the medical devices. When the ultrasonic guide bracket is used for puncture, the puncture needle is preferably ensured to be coplanar with the middle section of the ultrasonic probe, so that the position of the puncture needle can be always clearly displayed in an ultrasonic view during puncture, and the judgment of a doctor on the position of the puncture needle can be influenced. Therefore, the current medical situation needs an ultrasound guide bracket applicable to different types of ultrasound probes, which can be conveniently and quickly fixed on various ultrasound probes, can guide puncture needles with various diameters in an adjustable puncture direction, is low in cost, simple in operation, and can be used for one time or repeatedly, so as to meet different interventional diagnosis and treatment requirements and the requirement of repeated interventional training of ultrasound interventional physicians.

In view of the above, chinese patent application No. CN201910479997.6 discloses a puncture frame for ultrasound interventional puncture, which can be connected to an ultrasound transducer having an imaging surface that is in contact with a surface of a living body and can pass an ultrasound signal, the puncture frame comprising: the puncture needle fixing part is used for detecting the puncture angle of the puncture needle relative to the imaging surface in real time, and the angle detection unit and the connecting piece are used for detecting the puncture angle of the puncture needle relative to the imaging surface in real time. The connecting piece is rotatably connected with the puncture needle fixing piece so that the puncture needle fixing piece can continuously adjust the puncture angle. Nevertheless the utility model discloses the people is realizing the embodiment of the utility model provides an in-process, find above-mentioned technical scheme still to specific ultrasonic probe and the guide bracket of design preparation, to the ultrasonic probe compatibility shortcoming of different shapes, its shape, structure are comparatively complicated moreover, and the cost is higher, is not conform to low cost, easy operation, disposable or the requirement of used repeatedly.
