Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of this utility model.

[0032] As recorded in the background art, the traditional method of injecting fat particles mainly relies on the manual operation of doctors, that is, using a traditional syringe to manually push and pull the piston to control the injection speed and dose. Although this method is simple and intuitive, there are many limitations in actual operation. First of all, manual operation is difficult to ensure the accuracy of injection, especially in controlling the injection depth and uniformity. It is easy to cause uneven or excessive injection due to human factors, thus affecting the surgical effect. Secondly, manual operation has low efficiency and long surgical time, increasing the pain of patients and surgical risks.

[0033] To solve this technical problem, this utility model provides a posterior space layer particle injection device, which is applied to the injection of fat particles in the posterior space layer of the breast.

[0034] Specifically, please refer to Figures 1 - 3, the posterior space layer particle injection device specifically includes:

[0035] A handle 1, a connecting rod 103 is movably arranged inside the handle 1. One end of the connecting rod 103 passes through the handle 1 and is provided with a piston main body 201. A syringe 3 is sleeved on the outer surface of the piston main body 201. One end of the syringe 3 is fixedly connected with a wing plate 301. A limiting member is arranged between the wing plate 301 and the handle 1. A driving member is arranged inside the handle 1. The driving member is used to drive the connecting rod 103 to expand and contract so as to realize the movement of the piston main body 201.

[0036] For the posterior space layer particle injection device provided by the present utility model, in this application, the driving member is provided, and the driving member is used to drive the connecting rod 103 to expand and contract so as to realize the movement of the piston main body 201, thereby realizing automatic injection, being able to accurately control the injection speed and dosage, ensuring that fat particles are evenly and accurately injected into the posterior space layer of the breast, reducing injection errors, and improving the surgical effect; the automated operation significantly improves the injection efficiency, reduces the manual operation time during the operation, shortens the overall operation time, and is beneficial to the postoperative recovery of patients.

[0037] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings.

[0038] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0039] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0040] Example 1, please refer to Figures 1 - 3 , a posterior space layer particle injection device, including a handle 1, a connecting rod 103 is movably arranged inside the handle 1. One end of the connecting rod 103 passes through the handle 1 and is provided with a piston main body 201. A syringe 3 is sleeved on the outer surface of the piston main body 201. One end of the syringe 3 is fixedly connected with a wing plate 301. A limiting member is arranged between the wing plate 301 and the handle 1. A driving member is arranged inside the handle 1. The driving member is used to drive the connecting rod 103 to expand and contract so as to realize the movement of the piston main body 201. In this application, the driving member is provided, and the driving member is used to drive the connecting rod 103 to expand and contract so as to realize the movement of the piston main body 201, thereby realizing automatic injection, being able to accurately control the injection speed and dosage, ensuring that fat particles are evenly and accurately injected into the posterior space layer of the breast, reducing injection errors, and improving the surgical effect; the automated operation significantly improves the injection efficiency, reduces the manual operation time during the operation, shortens the overall operation time, and is beneficial to the postoperative recovery of patients.

[0041] Furthermore, as Figure 2 shown, one end of the connecting rod 103 close to the piston body 201 is fixedly connected with the connecting rod 103. The outer surface of the connecting rod 103 is threadedly connected with a connecting pipe 2. One end of the connecting pipe 2 is fixedly connected with the piston body 201. By rotating the connecting pipe 2 to separate the connecting pipe 2 from the threaded rod 104, the piston body 201 can be removed for replacement or cleaning, ensuring the hygiene and usage effect of the device. This enables the device to be reused, reducing medical costs. At the same time, timely replacement and cleaning can effectively avoid the risk of cross-infection, providing a more reliable guarantee for the health of patients.

[0042] Embodiment 2 further optimizes the posterior space layer particle injection device provided in Embodiment 3. Specifically, as Figure 4 shown, the driving member includes a motor 101 installed in the handle 1. The output shaft of the motor 101 is connected with a lead screw 102. A threaded groove is formed in the connecting rod 103. The outer surface of the lead screw 102 is threadedly connected with the threaded groove. By driving the lead screw 102 to rotate, the motor 101 can drive the connecting rod 103 to move horizontally. As a power source, the motor 101 can convert the rotational motion of the motor 101 into the horizontal movement of the connecting rod 103 through the threaded connection between the lead screw 102 and the connecting rod 103. This transmission method is stable and reliable, capable of precisely controlling the moving distance and speed of the connecting rod 103, thereby ensuring the accuracy of the injection process. Uniform injection force can reduce damage to the patient's tissue, and a stable power source can ensure that the surgical process is not interfered by unexpected factors.

[0043] Furthermore, the motor 101 is externally connected with a controller for controlling the rotation speed and rotation direction of the motor 101, improving the applicability of the device. The precise control of the controller can meet the requirements of different surgical stages, providing more operation options for doctors. At the same time, this also enables the device to adapt to the individual differences of different patients, improving the success rate of the surgery.

[0044] Furthermore, as Figure 3 shown, a limiting groove is formed in the handle 1. The outer surface of the connecting rod 103 is slidably connected with the inner wall of the limiting groove. The limiting of the connecting rod 103 by the limiting groove enables the connecting rod 103 to only move linearly without rotation, reducing the injection deviation that may be caused by the rotation of the connecting rod 103, enabling the fat particles to be accurately injected into the target position. At the same time, it also reduces the difficulty of the surgical operation and improves the surgical efficiency.

[0045] Furthermore, as Figure 1 、 Figure 2 and Figure 4As shown, the limiting member includes a hand-tightening bolt 4 threadedly connected to the handle 1. A clamping plate 401 is sleeved on the outer surface of the hand-tightening bolt 4. The wing plate 301 is clamped between the clamping plate 401 and the handle 1. By rotating the hand-tightening bolt 4, the distance between the clamping plate 401 and the handle 1 can be adjusted. Through the mutual cooperation of the clamping plate 401, the handle 1 and the hand-tightening bolt 4, the wing plate 301 can be clamped and fixed, and then the syringe 3 can be fixed, firmly fixing the syringe 3 to ensure the stability of the injection process. This fixing method makes the syringe 3 not shake or shift during the injection process, ensuring the accuracy and safety of the injection. At the same time, it also facilitates the operation of medical staff and improves the efficiency of the operation.

[0046] Furthermore, as Figure 2 and Figure 4 shown, a slot is also provided on the handle 1. A limiting rod 402 is inserted into the slot. One end of the limiting rod 402 passes through the slot and is fixedly connected to the clamping plate 401. The limiting rod 402 can support and limit the clamping plate 401 to improve the stability of the movement of the clamping plate 401, further enhancing the fixing effect of the syringe 3. The presence of the limiting rod 402 makes the movement of the clamping plate 401 smoother, thus ensuring that the fixing of the syringe 3 is more firm, which helps to improve the precision and safety of the operation and reduce the operation risk.

[0047] Example 3 further optimizes the posterior clearance layer particle injection device provided in Example 1 or 2. Specifically, as Figure 1 and Figure 2 shown, a needle 302 is connected to the end of the syringe 3 away from the wing plate 301. The needle 302 is used to pierce the target tissue.

[0048] Furthermore, as Figure 1 shown, a protective sleeve 303 is sleeved on the outer surface of the needle 302. The protective sleeve 303 is used for protecting the needle 302, reducing the situation of needle 302 damage, extending the service life of the needle 302. The protective sleeve 303 can effectively prevent the needle 302 from being damaged during storage and transportation, reducing the medical cost.

[0049] Furthermore, as Figure 1As shown, a connecting seat 5 is fixedly connected to the bottom of the handle 1. A connecting hole adapted to the protective sleeve 303 is provided on the connecting seat 5. During use, after the protective sleeve 303 is removed from the outer surface of the needle 302, it can be inserted into the connecting hole, which can reduce the loss of the protective sleeve 303 on the one hand. On the other hand, after the protective sleeve 303 is inserted into the connecting hole, it will contact the outer surface of the wing plate 301, playing an auxiliary supporting role for the wing plate 301 and enhancing the stability of the device. This design improves the reliability and safety of the operation, avoids the inconvenience caused by the loss of the protective sleeve 303, and the auxiliary support for the wing plate 301 further enhances the overall stability of the device, ensuring the smooth progress of the operation.

[0050] The usage process of the posterior space layer particle injection device provided by the present utility model is as follows:

[0051] First, the motor 101 drives the screw rod 102 to rotate, so that the connecting rod 103 extends, and then the piston body 201 moves towards the needle 302. After removing the protective sleeve 303, it is inserted into the connecting hole, as shown in Figure 5 Then, the motor 101 drives the piston body 201 to move away from the needle 302 to extract the injection substance. After the injection substance is extracted, the needle 302 is inserted into the target tissue, and then the motor 101 drives the piston body 201 to move towards the needle 302 to inject the injection substance in the syringe 3;

[0052] After use, the protective sleeve 303 is removed from the connecting hole and then sleeved on the outer surface of the needle 302. Loosen the hand-tightening bolt 4, rotate the wing plate 301 so that the wing plate 301 is separated from the two clamping plates 401, and pull the syringe 3 away from the handle 1 so that the syringe 3 is separated from the piston body 201 to remove the syringe 3, and rotate the connecting pipe 2 so that the connecting pipe 2 is separated from the threaded rod 104 to remove the piston body 201;

[0053] During installation, screw the connecting pipe 2 onto the outer surface of the threaded rod 104, and then insert the syringe 3 and the piston body 201. When the wing plate 301 contacts the handle 1, rotate the wing plate 301 so that the wing plate 301 rotates between the clamping plate 401 and the handle 1, and tighten the hand-tightening bolt 4 so that the clamping plate 401 clamps the wing plate 301.
