Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to a clinical puncture device. Background Art

[0002] Puncture, a common surgical term in medicine, is a diagnostic and treatment technique that involves inserting a puncture needle into a body cavity to extract secretions for testing, injecting gas or contrast agent into the body cavity for angiography, or injecting drugs into the body cavity. The purpose of puncture is to draw blood for testing, blood transfusion, infusion, and catheter insertion for angiography. During cardiovascular puncture surgery, usually there are two routes of entry: entering from the radial artery and entering through the femoral artery. First, the patient is placed in the operating room and locally anesthetized at the puncture point of the radial artery, and then the puncture needle is inserted. After our puncture needle penetrates the radial artery, a guide wire is then inserted. When the puncture needle penetrates the radial artery, the blood inside the blood vessel will spray out with the puncture needle, contaminating the surgical cloth (surgical gown) at that location and the gloves of the doctor when holding the puncture needle. Both will be contaminated by blood, and the blood sticking to the gloves can easily affect the doctor's ability to pick up other instruments and stick to the instruments. Therefore, a clinical puncture device is proposed. Summary of the invention

[0006] Preferably, a fixing ring is fixedly provided on one side of the inner part of the circular tube near the connecting pipe head, a plurality of through holes are provided inside the fixing ring, a fixing shell is fixedly provided on the inner side of the fixing ring and one side of the circular tube, a disc is movably provided on the inner side of the fixing shell, a plurality of driving ports are provided on the inner side of the disc, a plurality of switch sheets are movably provided on one end of the inner side of the fixing shell near the disc, a rotating shaft is fixedly provided on one end of the plurality of switch sheets, a movable shaft is fixedly provided on the other end of the plurality of switch sheets, and the two groups of switch sheets are fixedly provided with a plurality of rotating shafts. A group of internal switch sheets in the fixed shell near the pipe head are partially set as rubber sheets, the inner sides of the two groups of fixed shells are opened with openings, a guide pipe is fixedly set between the two groups of discs, and a plurality of groups of blood overflow holes are opened on the guide pipe, a bevel gear ring is fixedly set on the outer side of the guide pipe near a group of fixed shells, a round rod is movably set on the upper side of the circular tube corresponding to the position of the bevel gear ring, a bevel gear is fixedly set on the lower end of the round rod, a control block is fixedly set on the upper end of the round rod, and a guide wire is set on the inner sides of the two groups of fixed shells.

[0007] Preferably, the interiors of the puncture needle, the round tube and the guide head are connected, the connector and the connecting head are threadedly connected, and the guide blood vessel is made of a soft material.

[0008] Preferably, the limiting ring is limited to one side of the two groups of movable rings, the movable ring and the plurality of groups of damping strips are arranged for damping rotation, and the lower side of the supporting foot is arranged at an angle.

[0009] Preferably, the fixing ring is located on one side close to the connecting pipe head, and a plurality of groups of through holes are arranged in a circular pattern.

[0010] Preferably, the shapes of the switch pieces in the two groups of fixed shells are set differently, a group of internal switch pieces in the two groups of fixed shells close to the puncture needle is in an open state, and a group of internal switch pieces in the two groups of fixed shells away from the puncture needle is in a closed state and fits against the outside of the guide wire.

[0011] Preferably, the driving port is arranged to be inclined, the rotating shaft and the fixed shell are arranged to be movably rotatable, and the movable shaft is movably arranged inside the driving port.

[0012] Preferably, the guide tube and the overflow hole are communicated with the interior of the round tube, the bevel gear ring is meshed with the bevel gear, and the round rod passes through the upper side of the round tube.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The control block drives the round rod and the bevel gear to rotate, drives the meshing bevel gear ring to rotate, drives the guide tube and the two sets of discs to rotate together, and the two rotating sets of discs push the movable shafts set on the inner sides of the several sets of driving ports, so that the several sets of switch pieces rotate along the rotating shafts respectively. Since the original states of the several sets of switch pieces set on both sides are open and closed, the several sets of switch pieces of the controlled rubber sheet will form a closed state, while the switch pieces on the other side are in an open state, so as to prevent blood from spraying directly through the puncture needle and the round tube, and prevent blood from spraying directly and contaminating the doctor's gloves.

[0015] 2. After the blood is collected by the blood bag, the guide wire is inserted into one side of the guide head and into the inside of several groups of switch sheets and the guide tube on both sides. Since the inner sides of several groups of switch sheets close to the puncture needle are soft rubber sheets, they can be pushed open with a slight push of the guide wire, and the rubber sheets can also fit on the outside of the guide wire, and gaps are formed between them. The blood that may flow out, when flowing into the guide tube, is circulated through the overflow hole and the through hole into the inside of the round tube and the tube head, avoiding blood overflowing from the inside of the round tube and the guide head, and further reducing the possibility of contamination.

[0016] 3. The puncture needle is inserted into the patient's radial artery, and blood is ejected through the puncture needle and the round tube. The ejected blood is collected inside the blood bag through the connecting head and the guide blood vessel. The threaded connection between the connector and the connecting head facilitates the subsequent disassembly of the blood bag and the separate treatment of blood and the instrument.

[0017] 4. Through two groups of supporting feet and movable rings, the device can be adjusted to different positions by damping the rotation outside several groups of damping strips. For example, when it is unfolded into a flat state, it can assist the doctor in holding the device for puncture. When it is rotated downward to form a triangular state, it can be supported on the arm to stabilize the puncture needle. The supporting feet themselves are tilted, so when supported, the opening of the guide head on one side will tilt upward, and the overflowed blood will not easily flow out.
