Description

A anesthesia needle auxiliary positioning device for nerve block

Technical Field

The utility model relates to the field of medical auxiliary machinery, more specifically say, relate to an anesthesia needle auxiliary positioning device for nerve block.

Background

Before the femoral nerve block operation is carried out to the patient, in order to reduce the painful sense of perception among the patient's operation, often need carry out anesthesia injection to patient's operation position, but often there is not positioner among the ordinary anesthesia injection process, make the doctor be difficult to find accurate injection point, and when the injection, doctor's hand rocks easily, thereby bring unnecessary misery for the patient, anesthesia positioner among the prior art, accommodation process is comparatively complicated, and often use kelly or draw-in groove to carry out the mode of fixing, make the regulation accurate inadequately, and also be difficult to carry out accurate location to the position of inserting the needle.

Patent document CN213047184U discloses a positioning device for nerve block anesthesia needle. The device is characterized in that through the mutual matching between the fixing plate, the spotlight, the sleeve, the internal thread, the external thread, the fixing ring, the claw shell, the movable block and the anesthetic needle head, when the anesthetic needle head is required to be positioned, a user can rotate the fixing plate rightwards to enable the spotlight to be clamped into the sleeve, then rotate the fixing ring backwards through rotation to enable the internal thread to be separated from the external thread gradually, so that the user can adjust the angle of the sleeve according to actual requirements, when the position of the spotlight focused on the skin of a patient is coincident with the position of an injection point, the fixing ring is rotated forwards to enable the claw shell to be tightened, then the spotlight is pulled out of the sleeve and the anesthetic needle head is placed into the sleeve, so that the angle of the anesthetic needle head is positioned, and the device can accurately position the angle and the position of the anesthetic needle head when the patient needs to be anesthetized, the pain of the patient caused by difficulty in finding the accurate injection angle during injection is relieved, and the adjustment process is simple and convenient.

Although the device has more beneficial effects, the following problems still exist: the device presss from both sides tightly fixedly to the movable block through the claw shell, and the movable block is the cylinder type setting, then difficult avoiding the movable block to rotate in the claw shell, and this is higher with the coefficient of friction of movable block contact surface to the claw shell, leads to the device performance to reduce. In view of this, we propose an anesthetic needle auxiliary positioning device for nerve block.
