Description

Technical Field

[0001] The utility model relates to the field of plastic surgery and beauty instruments, in particular to a cavity separation instrument used in endoscopic breast augmentation surgery. Background Art

[0002] Endoscopic breast augmentation is a minimally invasive procedure using endoscopic technology. Through a small incision, a cavity suitable for implant placement is created. This technique relies on specialized instruments such as a cavity separator to precisely separate breast tissue and pectoral muscle, ensuring safe implant placement. Compared to traditional methods, endoscopic breast augmentation offers the advantages of less trauma and a faster recovery time. Technological advances have enabled more precise surgery and reduced damage to surrounding tissue.

[0003] In endoscopic breast augmentation surgery, a cavity separator is a key medical device used to create a cavity beneath the breast tissue suitable for implant placement. This device precisely separates the breast tissue and pectoral muscle to create a space suitable for the implant. Cavity separators are typically designed to facilitate cavity creation under endoscopic guidance. Applications include plastic breast surgery, breast reconstruction, and other minimally invasive procedures requiring the creation of a specific cavity within the body.

[0004] The existing cavity separator is similar to the structure of tweezers. The surgeon can manually control the degree of its opening to achieve the purpose of separating breast tissue and pectoral muscles. However, after a long period of surgery, the doctor's hands holding the instrument will become tired, which will cause the instrument to shake inside the body, affecting the surgical effect. Therefore, a cavity separation instrument is proposed for endoscopic breast augmentation surgery to solve the above problem. Utility Model Content

[0005] In order to make up for the above deficiencies, the present invention provides a cavity separation instrument for endoscopic breast augmentation surgery, aiming to improve the problem that the cavity separation instrument is difficult to accurately control during a long operation.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a cavity separation instrument for endoscopic breast augmentation surgery, comprising a support rod one and a support rod two, wherein the support rod one and the support rod two are rotatably connected, the right ends of the support rod one and the support rod two are fixedly connected with a handle, an arc spring is fixedly connected between the two handles, the interior of the support rod two is slidably connected with an arc rod, the outer wall of the support rod two is fixedly connected with a rotating shaft, the outer side of the rotating shaft is rotatably connected with a buckle, the left ends of the support rod one and the support rod two are installed with a support assembly, and the support assembly is used to create a cavity inside the breast.

[0007] As a further description of the above technical solution:

[0008] The support assembly includes two sleeves, the left end of the sleeve is fixedly connected to a separation support plate, a fixed inner groove is opened inside the sleeve, and multiple sections of protrusions are inserted into the interior of the sleeve, one of the multiple sections of protrusions is fixedly connected to the left end of the first support rod, and the other multiple sections of protrusions is fixedly connected to the left end of the second support rod.

[0009] As a further description of the above technical solution:

[0010] A guide rod is slidably connected between the two handles, and the arc spring is sleeved on the outer side of the guide rod.

[0011] As a further description of the above technical solution:

[0012] A handle is fixedly connected to the right side of the buckle, and the handle is used to control the rotation of the buckle.

[0013] As a further description of the above technical solution:

At this time, the separation support plate can be inserted into the breast through the incision, and a suitable position for placing the prosthesis can be found through the endoscope. Then, the force on the handles is relaxed, and the soft tissue inside the breast is separated by the separation support plate. After reaching the appropriate separation angle, the handles can be moved to make the buckle stuck in the groove inside the arc rod. At this time, there is no need to continue to apply grip force to the handles, which not only achieves accurate separation of the soft tissue inside the breast, but also relieves the doctor's hand fatigue to a certain extent.

[0023] 2. In the present invention, the multi-segment rubber protrusions on the outside of the support rod can insert the support rod into the sleeve. The multi-segment protrusions and the sleeve can ensure that the separation support plate is firmly fixed to the end of the support plate. At the same time, after the operation is completed, the separation support plate can be pulled out with force to achieve separation between the separation support plate and the support rods 1 and 2, ensuring that the internal gap structure of the entire instrument is completely exposed, making the instrument disinfection more thorough.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 - Figure 3The utility model provides an embodiment of a cavity separation instrument for endoscopic breast augmentation surgery, comprising a support rod 1 3 and a support rod 2 4, characterized in that: the support rod 1 3 and the support rod 2 4 are rotatably connected, the right ends of the support rod 1 3 and the support rod 2 4 are fixedly connected with a handle 1, an arc spring 2 is fixedly connected between the two handles 1, an arc rod 5 is slidably connected inside the support rod 2 4, the outer wall of the support rod 2 4 is fixedly connected with a rotating shaft 10, and a buckle 9 is rotatably connected to the outer side of the rotating shaft 10, and a support assembly is installed on the left end of the support rod 1 3 and the support rod 2 4, and the support assembly is used to create a cavity inside the breast, a guide rod 12 is slidably connected between the two handles 1, the arc spring 2 is sleeved on the outer side of the guide rod 12, and a handle 11 is fixedly connected to the right side of the buckle 9, and the handle 11 is used to control the rotation of the buckle 9, the rear end of the arc rod 5 is fixedly connected to the front side of the support rod 1 3, and a plurality of grooves 8 are opened inside the arc rod 5, and the buckle 9 is inserted into the inside of one of the grooves 8.

[0033] Specifically, in this embodiment, the doctor first uses an endoscope to pass through the incision to detect a suitable position for placing the prosthesis, and then needs to hold the two handles 1 to compress the arc spring 2. The guide rod 12 inside the arc spring 2 ensures the stability of the deformation process of the arc spring 2. Then, the separation instrument is passed through the incision into the breast, and the handle 1 is released at the appropriate position. Under the action of the arc spring 2, the support rod 1 3 and the support rod 2 4 are separated, and the two separation support plates 7 stretch the surrounding soft tissue. The doctor can judge the degree of soft tissue separation. When the separation angle is appropriate, the handle 11 is moved to make the buckle 9 clamped downward in a groove 8 inside the arc rod 5. At this time, the doctor does not need to apply force to the handle 1, which not only ensures the accurate separation of the soft tissue inside the breast, but also relieves the fatigue caused by the doctor holding the handle 1 for a long time.

[0034] Reference Figure 4 - Figure 5 The support assembly includes two sleeves 6, the left end of the sleeve 6 is fixedly connected to the separation support plate 7, the interior of the sleeve 6 is provided with a fixed inner groove 14, and the interior of the sleeve 6 is plugged with multi-segment protrusions 13, one of the multi-segment protrusions 13 is fixedly connected to the left end of the support rod 1 3, and the other multi-segment protrusion 13 is fixedly connected to the left end of the support rod 2 4. The sleeve 6 and the multi-segment protrusions 13 are both made of rubber. There is an interference fit between the multi-segment protrusions 13 and the fixed inner groove 14, and the multi-segment protrusions 13 can be deformed inside the fixed inner groove 14 when subjected to force.

[0035] Specifically, a multi-segment protrusion 13 is fixed on the outside of support rod 1 3 and support rod 2 4, and a fixed inner groove 14 is opened inside the sleeve 6, and support rod 1 3 and support rod 2 4 are inserted into the interior of the sleeve 6. Since the multi-segment protrusion 13 and sleeve 6 are made of rubber material, and there is an interference fit between the multi-segment protrusion 13 and the fixed inner groove 14, the multi-segment protrusion 13 is deformed inside the fixed inner groove 14, and the separation support plate 7 on the left side of the sleeve 6 is quickly fixed to support rod 1 3 and support rod 2 4, saving the installation time of the equipment. After the operation, the separation support plate 7 can be pulled out forcefully to achieve complete separation between the separation support plate 7 and support rod 1 3 and support rod 2 4, which is convenient for disinfection of the equipment after surgery.

[0036] Working principle: Before performing the operation, an endoscope is needed to pass through the incision to detect the appropriate position for placing the prosthesis. Then the doctor needs to hold the two handles 1 to make the support rod 1 3 and the support rod 2 4 close to each other, and the two separation support plates 7 also fit together, and the arc spring 2 is compressed. At this time, the separation support plate 7 can be passed through the incision into the breast. After finding the appropriate position, the force on the handle 1 is relaxed. The elastic force of the arc spring 2 will cause the two separation support plates 7 to open to both sides, separating the soft tissue inside the breast. The doctor needs to move the handle 11 after reaching the appropriate separation angle, so that the buckle 9 is stuck in the groove 8 inside the arc rod 5. At this time, there is no need to continue to apply grip force to the handle 1, which not only achieves precise separation of the soft tissue inside the breast, but also relieves the doctor's hand fatigue to a certain extent. The rubber multi-segment protrusions 13 on the outside of support rod 1 3 and support rod 2 4 can insert support rod 1 3 and support rod 2 4 into the sleeve 6, and the interference fit between the multi-segment protrusions 13 and the fixed inner groove 14 makes the sleeve 6 and the separation support plate 7 firmly fixed to the ends of support rod 1 3 and support rod 2 4, thereby achieving rapid fixation of the separation support plate 7, reducing the time for equipment installation, and providing a larger area of support effect. The doctor can observe the situation inside the incision more clearly to smoothly perform the operation. After the operation, it is only necessary to pull out the separation support plate 7 with force, so that the separation support plate 7 is completely separated from support rod 1 3 and support rod 2 4, ensuring that the various gap structures of the instrument are completely exposed, which is convenient for thorough cleaning and disinfection of the instrument.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
