Description

Technical Field

[0001] This utility model relates to the field of facial injection device technology, specifically, to a syringe for filling facial fat. Background Technology

[0002] Facial filler surgery involves extracting fat from other parts of the body besides the face and then injecting the extracted fat into the face using a syringe. When doctors have been performing the procedure for a long time, they are prone to fatigue, which can affect their concentration and the accuracy of the procedure. At this time, when the doctor picks up the syringe, they may squeeze the syringe, which can cause the fat in the syringe to leak into the surgical area and cause contamination. Utility Model Content

[0003] This utility model provides a solution that can overcome one or more defects of the prior art.

[0004] According to the present invention, an injector for filling facial fat includes an injector body, which includes an injection barrel, a needle, and a push rod that extends into the injection barrel. The side wall of the injection barrel away from the needle extends to both ends to form baffles. A limiting plate assembly for clamping the push rod is provided at the baffles. A reset mechanism is provided at the limiting plate assembly. The reset mechanism is used to release the clamping of the push rod when the doctor pushes the push rod.

[0005] With this invention, when using a syringe, the surgeon first inserts the needle into the patient's face, then pushes the plunger on the syringe to inject fat. During the injection, the surgeon squeezes the plunger with his thumb, while his index and middle fingers hook the baffle. When the thumb squeezes the plunger, the index and middle fingers push the connecting plate upward, which in turn pushes the guide plate to move along the guide hole. This allows the guide plate to push the squeezing plate away from the plunger, thereby releasing the clamp on the plunger and making it easier for the surgeon to push the plunger to complete the fat injection.

[0006] Before the syringe is used, the spring will squeeze the connecting plate, which will pull the guide plate. The guide plate will then pull the squeezing plate, which will press against the plunger and hold it in place. Fat can only be injected after the doctor removes the squeezing plates on both sides of the plunger at the same time. This prevents the doctor from touching the plunger with their fingers when they are overly fatigued, causing fat to spill out from the needle and contaminate the operating room.

[0007] Preferably, the baffle has two guide holes that pass through the baffle and are inclined; the limiting plate assembly includes limiting members on both sides of the push rod, the limiting members include a pressing plate that is arranged along the length of the baffle and extends toward the push rod, the end of the pressing plate away from the push rod has two inclined guide plates that pass through the guide holes; the end of the guide plate away from the pressing plate has a connecting plate that connects the two guide plates; the reset mechanism includes a spring arranged between the connecting plate and the baffle.

[0008] With this invention, the guide plate moves along the guide hole, thereby improving the stability of the guide plate during movement; the limiting plate assembly and the reset mechanism can ensure that the doctor can smoothly push the push rod when injecting fat; and can prevent the doctor from accidentally touching the push rod, causing fat to spill out from the needle.

[0009] Preferably, the end of the extrusion plate near the push rod is provided with a slot for the push rod to be engaged.

[0010] With this invention, the contact area between the slot and the push rod is larger, increasing the friction and reducing the possibility of the push rod moving when the extrusion plate presses against it.

[0011] Preferably, a rubber pad is provided inside the card slot.

[0012] With this invention, the rubber pad contacts the push rod, increasing the friction between the push rod and the extrusion plate, thus preventing the push rod from moving when squeezed by the extrusion plate.

[0013] Preferably, the baffle and the connecting plate are respectively provided with a first limiting groove and a second limiting groove for the two ends of the spring to extend into.

[0014] With this invention, the first limiting groove and the second limiting groove limit the spring, preventing the spring from detaching from the baffle and the connecting plate.

[0015] Preferably, the guide plate and the connecting plate are bonded together.

[0016] With this invention, when installing the limiting component, first pass the guide plate through the guide hole, then glue the connecting plate to the guide plate, and then place the spring into the first limiting groove and the second limiting groove, thus making it convenient for installers to install the limiting component on the baffle.

[0021] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0022] Example 1

[0023] like Figure 1-4 As shown, this embodiment provides an injector for filling facial fat, which includes an injector body 100. The injector body 100 includes an injection barrel 140, a needle 150, and a push rod 110 extending into the injection barrel 140. The side wall of the injection barrel 140 away from the needle 150 extends to both ends to form a baffle 130. A limiting plate assembly 120 for clamping the push rod 110 is provided at the baffle 130. A reset mechanism is provided at the limiting plate assembly 120. The reset mechanism is used to release the clamping of the push rod 110 when the doctor pushes the push rod 110.

[0024] In this embodiment, when using a syringe, the surgeon first inserts the needle 150 into the patient's face, and then pushes the plunger 110 on the syringe to inject fat. During the injection, the surgeon squeezes the plunger 110 with his thumb, while his index and middle fingers hook the baffle 130. When the thumb squeezes the plunger 110, the index and middle fingers push the connecting plate 270 upward. The upward movement of the connecting plate 270 pushes the guide plate 280 to move along the guide hole 410, so that the guide plate 280 pushes the squeezing plate 240 away from the plunger 110, thereby releasing the clamping on the plunger 110 and making it easier for the surgeon to push the plunger 110 to complete the fat injection.

[0025] Before the syringe is used, the spring 250 will squeeze the connecting plate 270, causing the connecting plate 270 to pull the guide plate 280. The guide plate 280 pulls the squeezing plate 240, causing the squeezing plate 240 to press against the push rod 110, thereby clamping the push rod 110. Fat can only be injected after the doctor removes the squeezing plates 240 on both sides of the push rod 110 at the same time. This prevents the doctor from touching the push rod 110 with their fingers when they are overly fatigued, causing fat to spill out from the needle 150 and contaminate the operating room.

[0026] In this embodiment, the baffle 130 is provided with two guide holes 410 that pass through the baffle 130 and are inclined; the limiting plate assembly 120 includes limiting members 230 provided on both sides of the push rod 110, the limiting members 230 include a pressing plate 240 that is provided along the length direction of the baffle 130 and extends toward the push rod 110, the end of the pressing plate 240 away from the push rod 110 is provided with two inclined guide plates 280 that pass through the guide holes 410; the end of the guide plate 280 away from the pressing plate 240 is provided with a connecting plate 270 that connects the two guide plates 280; the reset mechanism includes a spring 250 provided between the connecting plate 270 and the baffle 130.

[0027] In this embodiment, the guide plate 280 moves along the guide hole 410, thereby improving the stability of the guide plate 280 during movement; the limiting plate assembly 120 and the reset mechanism can ensure that the doctor can smoothly push the push rod 110 when injecting fat; and can prevent the doctor from accidentally touching the push rod 110, causing fat to spill out from the needle 150.

[0028] In this embodiment, the end of the extrusion plate 240 near the push rod 110 is provided with a slot 210 for the push rod 110 to be inserted.

[0029] In this embodiment, the contact area between the slot 210 and the push rod 110 is larger, which increases the friction and reduces the possibility of the push rod 110 moving when the pressing plate 240 presses against it.

[0030] In this embodiment, a rubber pad 220 is provided inside the card slot 210.

[0031] In this embodiment, the rubber pad 220 contacts the push rod 110, increasing the friction between the push rod 110 and the extrusion plate 240, and preventing the push rod 110 from moving when it is extruded by the extrusion plate 240.

[0032] In this embodiment, the baffle 130 and the connecting plate 270 are respectively provided with a first limiting groove 260 and a second limiting groove 420 into which the two ends of the spring 250 extend.

[0033] In this embodiment, the first limiting groove 260 and the second limiting groove 420 limit the spring 250, preventing the spring 250 from disengaging from the baffle 130 and the connecting plate 270.

[0034] In this embodiment, the guide plate 280 and the connecting plate 270 are bonded together.

[0035] In this embodiment, when installing the limiting member 230, firstly, the guide plate 280 is passed through the guide hole 410, then the connecting plate 270 is glued to the guide plate 280, and then the spring 250 is placed into the first limiting groove 260 and the second limiting groove 420, which makes it convenient for installers to install the limiting member 230 on the baffle 130.

[0036] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, all of which do not exceed the protection scope of this application.

[0037] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the embodiments shown are only part of the embodiments of the present invention. The actual structure is not limited to this. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
