Embodiment Construction

[0010] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0011] After skin preparation, first place the positioning sticker (5) on the patient's abdomen for measurement, and use scissors to subtract the excess positioning sticker (5). Tear off the internal tape of the positioning sticker (5), and stick the positioning sticker (5) on the patient's abdominal skin. After the positioning is completed, tear off the adhesive tape on the outside of the positioning sticker (5), align the bottom end of the longitudinal channel (1) of the fixer (2) with the positioning hole on the positioning sticker (5) and stick it together. Insert the puncture needle into the longitudinal hole (1) and stop after passing through the patient's peritoneum. The assistant screw in two bolts (3) respectively from the transverse holes (4) on both sides of the lower part of the holder, and tighten them inward until the fixed punctu...

The positioning plaster is provided with a porous double-surface sticky tape, the fixer comprises an upper component and a lower component, the upper component is provided with an upper long cylinder, the lower component is provided with a lower flat cylinder, the upper component and the lower component are connected each other, a vertical hole channel penetrating the upper end and the lower end is formed in the fixer, the length of the vertical hole channel is smaller than that of a puncturing syringe needle, a horizontal hole channel penetrating the left end and the right end is formed in the lower component of the fixer, the vertical hole channel is communicated with the horizontal hole channel in the lower component of the fixer, an inner thread is arranged in the horizontal hole channel and matched with outer threads on bolt screws screwed in from twoends of the horizontal hole channel, and the length of each bolt screw is larger than the radius of the lower component.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a lower abdominal puncture positioning and fixing device. Background technique [0002] At present, when performing lower abdominal puncture on a patient in clinical practice, the medical staff should first find the paramedian puncture point in the lower abdomen, which is located 1 cm above the midpoint of the line between the umbilical cord and the upper edge of the pubic symphysis, and 1 to 2 cm to the left or right. With no vital organs, puncture is safer and heals easily. Then the surgeon fixes the skin of the puncture site with his left hand, and the right hand holds the needle through the anesthetized site to puncture the abdominal wall vertically. When the needle-point resistance suddenly disappears, it shows that the needle tip has passed through the peritoneal wall. After the assistant puts on gloves, he uses sterile vascular forceps to help fix the needle. ...
