As shown in fig. 1 and 2, a facial fat suction needle with nerve monitoring according to the present utility model comprises:
The needle head 1 is provided with a hollow cavity, and one end of the needle head 1 is provided with an opening;
The connecting seat 2 is arranged at one end of the opening of the needle head 1 and is used for connecting negative pressure suction equipment;
the side hole 3 is formed in the side wall of one end of the needle head 1 penetrating into the skin, and the side hole 3 is communicated with the cavity in the needle head 1;
The nerve monitoring probe 4 is arranged at the end part of the needle head 1 penetrating into the skin side, and is electrically connected with the nerve monitoring instrument.
The diameter of the needle head 1 is 1.5-2mm, the inner diameter of the internal cavity is 0.5-2 mm, and the needle head is selected according to the extracted fat amount, the operation position and the like;
in some embodiments, the needle 1 may be configured as a double-hole needle: the length of the needle head 1 is 130mm, the diameter is 1.8mm, two side holes 3 are formed, the two side holes 3 are correspondingly formed in the periphery of the needle head, the included angle between the two side holes is 180 degrees, and the specific size of the side holes is as follows: the long diameter is 3mm, and the distance from the front end of the needle head 1 is 2mm; single side hole needle: the length of the needle 1 is 100mm, the diameter is 1.5mm, or the length of the needle 1 is 80mm, the diameter is 1.5mm, one side hole 3 is provided, and the size is as follows: the long diameter is 3mm, and the distance from the top end is 1.5mm.
For small area liposuction, smaller needles 1 and internal fat passages are typically used to reduce incision size and surgical trauma. For large area fat aspiration, a larger aspiration needle is required to complete the aspiration process more quickly.
The connecting seat 2 is used for connecting negative pressure suction equipment, the negative pressure suction equipment is generally a needle cylinder, and the connecting seat 2 is provided with a slot which is matched with the front end of the needle cylinder;
For other suction devices, a suction pump, namely a fat suction machine, can be adopted, and is connected and fixed with the connecting seat 2 to realize negative pressure suction;
The nerve monitoring probe 4 is arranged at the end part of the needle head 1 penetrating into one end of the skin, and a certain gap exists between the nerve monitoring probe and the suction side hole 3, so that the nerve position can be detected in advance, and the damage to the nerve in the suction process is prevented;
The nerve monitoring probe 4 is connected with a nerve detector, and generally adopts an electrical stimulation nerve detection device, and judges the nerve position by generating weak electrical stimulation to the nerve and receiving a feedback signal of the nerve.
The connection between the nerve monitoring probe 4 and the nerve detector is specifically as follows: a wire hole for threading is formed in the side wall of the needle head 1, one end of the wire hole is connected to the nerve monitoring probe 4, the connecting seat 2 is divided into two parts, one part is a first connecting part connected with the needle head 1, the other part is a second connecting part connected with negative pressure equipment, the diameter of the first connecting part is larger than that of the second connecting part, a stepped structure is formed, the diameter of the first connecting part is larger than that of a connecting pipeline of the negative pressure equipment, after the negative pressure connecting pipeline is connected with the second connecting part (in a threaded connection mode), a certain gap is formed between the first connecting part and the outer side of the negative pressure connecting part, the other end of the wire hole is formed at the gap, a circuit for connecting the nerve monitoring probe 4 with the nerve detector is arranged in the wire hole and cannot contact with a patient, and the outer part of the wire hole can be disinfected along with the needle head; meanwhile, in other embodiments, the wire hole directly penetrates out of the side wall of the first connecting part, so that connection of the negative pressure device and the second connecting part is prevented from being affected.
The connecting seat 2 is provided with a jack 5, and internal threads are arranged in the jack 5.
In order to conveniently connect the pillow and the negative pressure suction equipment, the stability is ensured, the internal threads are arranged in the jack 5, the suction pipe of the negative pressure suction equipment can be connected with the connecting seat 2 of the needle head 1 in a threaded manner, and the connection is more stable and is not easy to fall off.
The side hole 3 is an annular notch arranged on the needle head 1.
The side hole 3 is annularly arranged, so that the fat sucking process is more uniform, and meanwhile, the annular side hole 3 can provide more operation options. The doctor can selectively use the annular side hole 3 to perform fat suction according to the operation needs and the specific situation. This allows a more precise and flexible aspiration operation according to the different surgical fields and tissue characteristics, and the design of the annular lateral orifice 3 also reduces the risk of obstruction of the aspiration needle 1 portion. If there is only a single side hole 3, blockage may occur when adipose tissue is inhaled. While the annular side hole 3 is designed to increase the passage of adipose tissue into the vessel, reducing the possibility of blockage.
The nerve monitoring probe 4 is an electric stimulator for providing weak electric stimulation.
The end of the needle 1 penetrating the skin is provided with a blunt tip.
The needle head 1 is arranged in a blunt way;
Can reduce trauma and pain sensation: blunt tips can reduce trauma and injury to the patient's skin and tissue as compared to sharp tips. In some sensitive areas or for certain patients (e.g., children or elderly people), the use of blunt tips may reduce stinging and pain sensations.
Reducing the risk of bleeding and congestion: blunt tips are relatively smooth and less prone to damage to blood vessels and perivascular tissue. This may reduce the amount of bleeding during surgery or puncture and reduce the risk of forming blood stasis.
Avoiding tissue damage and loss: in some cases, such as liposuction or drug injection applications, the use of blunt tips may avoid excessive damage or destruction of the target tissue. Blunt tips can penetrate tissue more gently and reduce tissue damage and cell destruction.
Safety and controllability are improved: blunt designs are generally safer because they are less prone to accidental puncturing or scoring of surrounding tissue. In addition, blunt tips may provide better control, enabling a physician to more accurately manipulate and locate a target area.
In other embodiments, needle 1 may be configured to bend or otherwise reduce the difficulty of the procedure for different surgical sites.
The above specific embodiments may be combined with each other and some embodiments may not be repeated for the same or similar concepts or processes.
Any combination of the technical features of the above embodiments may be performed (as long as there is no contradiction between the combination of the technical features), and for brevity of description, all of the possible combinations of the technical features of the above embodiments are not described; these examples, which are not explicitly written, should also be considered as being within the scope of the present description.
The utility model has been described above with particularity and detail in connection with general description and specific embodiments. It should be noted that it is obvious that several variations and modifications can be made to these specific embodiments without departing from the scope of the present utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
