[0030] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] As recorded in the background art, traditional fat transplantation surgeries rely on doctors' manual operations, injecting fat particles into the target area through a syringe. However, this method has significant limitations. During the operation, it is necessary to constantly pay attention to the scale on the syringe. This method relying on human judgment is difficult to ensure the accuracy of each injection, and it is easy to have situations of over-injection or under-injection. Over-injection may lead to complications such as fat necrosis, local unevenness, and infection, while under-injection may not achieve the expected surgical effect.

[0032] To solve this technical problem, the present invention provides a fat layer particle injection device, which is applied to the injection of fat particles in the deep fat layer.

[0033] Specifically, please refer to Figures 1 - 4 , the fat layer particle injection device specifically includes:

[0034] Support base 1, a limiting groove 101 is provided at the top of the support base 1, a syringe 2 is placed in the limiting groove 101, a piston rod 204 is arranged in the syringe 2, a connecting piece is arranged on the piston rod 204, the connecting piece is connected with a sliding sleeve 404, a contact switch 3 is further installed on the support base 1, and the contact switch 3 is on the moving track of the sliding sleeve 404 to realize the triggering of the contact switch 3 when the sliding sleeve 404 moves.

[0035] The fat layer particle injection device provided by the present utility model. In this application, through the arranged sliding sleeve 404 and contact switch 3, the piston rod 204 can drive the sliding sleeve 404 to move during the moving process, and the sliding sleeve 404 can trigger the contact switch 3 during the moving process. That is, when the preset injection volume is reached, the contact switch 3 is triggered, thereby reminding the medical staff to stop injection, so as to ensure the accuracy of the injection volume.

[0036] In order to enable the personnel in the technical field 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 accompanying drawings.

[0037] 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.

[0038] It should be noted that similar reference numerals and letters represent 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 the subsequent drawings.

[0039] Embodiment 1, please refer to Figures 1 - 4 , a fat layer particle injection device, including a support base 1, a limiting groove 101 is provided at the top of the support base 1, a syringe 2 is placed in the limiting groove 101, a piston rod 204 is arranged in the syringe 2, a connecting piece is arranged on the piston rod 204, the connecting piece is connected with a sliding sleeve 404, a contact switch 3 is further installed on the support base 1, and the contact switch 3 is on the moving track of the sliding sleeve 404 to realize the triggering of the contact switch 3 when the sliding sleeve 404 moves. In this application, through the arranged sliding sleeve 404 and contact switch 3, the piston rod 204 can drive the sliding sleeve 404 to move during the moving process, and the sliding sleeve 404 can trigger the contact switch 3 during the moving process. That is, when the preset injection volume is reached, the contact switch 3 is triggered, thereby reminding the medical staff to stop injection, so as to ensure the accuracy of the injection volume. The contact switch 3 can be externally connected to an alarm to give an alarm reminder when the contact switch 3 is triggered.

[0040] Further, as Figure 1 and Figure 3As shown in the figure, a clamping plate 102 is provided on the support base 1. The clamping plate 102 contacts the syringe barrel 2. The clamping plate 102 is used to clamp and limit the syringe barrel 2. The setting of the clamping plate 102 further enhances the fixing effect on the syringe barrel 2, provides a more stable support for the injection operation. The clamping plate 102 is in direct contact with the syringe barrel 2, providing a clamping force from the side. Acting together with the limiting groove 101, the syringe barrel is effectively fixed in all directions, which can prevent the syringe barrel 2 from loosening or falling off during the injection process, ensuring the smooth progress of the injection.

[0041] Furthermore, as Figures 1 - 4 shown, through holes are provided on the clamping plate 102, threaded holes are provided on the support base 1, and a first hand-tightening bolt 103 is arranged between the through holes and the threaded holes. When the first hand-tightening bolt 103 is tightened, the effect of the clamping plate 102 clamping and limiting the syringe barrel 2 can be improved. The setting of the first hand-tightening bolt 103 makes the clamping operation of the clamping plate 102 more convenient and fast. Medical staff can easily adjust the clamping degree of the clamping plate 102 by rotating the hand-tightening bolt to ensure that the clamping force on the syringe barrel 2 is appropriate.

[0042] Example 2 further optimizes the fat layer particle injection device provided in Example 1. Specifically, as Figures 1 - 3 shown, the connecting member includes a first clamp seat 4 and a second clamp seat 401 respectively located on both sides of the piston rod 204. A second hand-tightening bolt 402 is connected between the second clamp seat 401 and the first clamp seat 4. The second hand-tightening bolt 402 connects the second clamp seat 401 and the first clamp seat 4 together so that the second clamp seat 401 and the second hand-tightening bolt 402 can clamp on the piston rod 204. Furthermore, when the piston rod 204 is pushed, the first clamp seat 4 can follow the piston rod 204 to move.

[0043] Furthermore, as Figure 1 shown, a scale 403 is fixedly connected to one side of the first clamp seat 4. A sliding sleeve 404 is sleeved on the outer surface of the scale 403. When the first clamp seat 4 moves, it can drive the scale 403 to move, and then drive the sliding sleeve 404 to move through the scale 403. The setting of the scale 403 provides an intuitive reference for the injection volume for medical staff. During the injection process, medical staff can accurately understand the progress and volume of the injection by observing the scale value on the scale 403, so as to better control the injection operation.

[0044] Furthermore, as Figure 1As shown, a third hand-tightening bolt 405 is threadedly connected to the sliding sleeve 404. One end of the third hand-tightening bolt 405 penetrates into the sliding sleeve 404 and contacts the scale 403. After loosening the third hand-tightening bolt 405, the sliding sleeve 404 can be pushed to move. Furthermore, the position of the sliding sleeve 404 can be adjusted according to the injection volume. The setting of the third hand-tightening bolt 405 makes the position adjustment of the sliding sleeve 404 more flexible and convenient. Medical staff can easily adjust the position of the sliding sleeve 404 on the scale 403 according to different injection requirements, so as to accurately set the preset injection volume. This adjustable design improves the applicability of the device and can meet the needs of different patients and treatment situations. At the same time, the threaded connection method of the hand-tightening bolt provides a stable fixing force to ensure that the sliding sleeve 404 will not move accidentally during the injection process, guaranteeing the accuracy of the injection volume.

[0045] Example 3 further optimizes the fat layer particle injection device provided in Example 1 or 2. Specifically, as Figure 5 shown, one end of the syringe barrel 2 is fixedly connected with a wing plate 206. The wing plate 206 contacts the side surface of the support base 1. The setting of the wing plate 206 can cooperate with the support base 1 to play a limiting role on the syringe barrel 2, so as to improve the stability of the syringe barrel 2 and effectively prevent the syringe barrel 2 from tilting or shaking during the injection process, ensuring that the flow direction of the injection substance is accurate.

[0046] Furthermore, as Figure 5 shown, one end of the syringe barrel 2 away from the wing plate 206 is fixedly connected with a connecting rod 203. The connecting rod 203 is connected with a needle head 201, and the needle head 201 is used to penetrate into the target tissue.

[0047] Furthermore, as Figure 5 shown, a protective sleeve 202 is sleeved on the outer surface of the needle head 201. The protective sleeve 202 is used for protecting the needle head 201 and reducing the situation of damage to the needle head 201.

[0048] Furthermore, as Figure 5 shown, a piston body 205 is arranged in the syringe barrel 2. One end of the piston rod 204 is fixedly connected with the piston body 205. When the piston rod 204 is pushed and pulled, it can drive the piston body 205 to move to extract and inject the injection substance.

[0049] The usage process of the fat layer particle injection device provided by the present utility model is as follows:

[0050] First, loosen the third hand-tightening bolt 405. Adjust the position of the sliding sleeve 404 according to the injection volume so that when the sliding sleeve 404 triggers the contact switch 3, the required injection volume is reached. After adjustment, tighten the third hand-tightening bolt 405. Then, remove the protective sleeve 202 and insert the needle 201 into the target tissue. Push the piston rod 204. The piston rod 204 pushes the piston body 205 to move, so as to push out the injection substance in the syringe 2 from the needle 201, realizing the injection of the injection substance. During this process, the piston rod 204 drives the scale 403 and the sliding sleeve 404 to move through the second clamp seat 401 and the first clamp seat 4. When the sliding sleeve 404 reaches the contact switch 3, the sliding sleeve 404 triggers the contact switch 3, and the injection can be stopped.

[0051] After use, unscrew the second hand-tightening bolt 402 to separate the second clamp seat 401 and the first clamp seat 4 from the piston rod 204. Loosen the first hand-tightening bolt 103 and then pull out the syringe 2 to remove the syringe 2. Then, insert a new syringe 2 into the limit groove 101 and tighten the first hand-tightening bolt 103. Clamp the second clamp seat 401 and the first clamp seat 4 onto the new piston rod 204 through the second hand-tightening bolt 402.

For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, an electrical connection, or communication with each other; it can be directly connected, or indirectly connected through an intermediate medium, and can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0053] Obviously, the above-described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. The drawings show the preferred embodiments of the present utility model, but do not limit the patent scope of the present utility model. The present utility model can be implemented in many different forms.
