Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a skin cutting device after hydroseparating inner and outer skin plates and a method of using the device. Background Art

[0002] The skin covering the glans penis (glans) is divided into two parts: the inner skin and the outer skin. The inner skin directly contacts the glans penis, while the outer skin continues onto the penis shaft. Excessive length of the skin covering the glans penis can lead to excessive secretions from the inner skin accumulating between the two parts, causing increased dirt. This dirt can irritate the glans penis, triggering a localized inflammatory reaction and causing glans inflammation. In severe cases, the inner skin may adhere to the glans penis, exacerbating the condition.

[0003] The most commonly used cutting device is the stapler, which consists of a housing, an annular cutting blade, a staple cartridge, a glans protective rod, a handle, and an adjustment knob. To use, first place the glans protective rod on the glans surface, with the inner skin covering the rod. Then, use the adjustment knob to adjust the housing and glans protective rod to the desired position and lock. Then, trigger the handle, and the annular cutting blade cuts from the outer skin to the inner skin, while the staples in the staple cartridge close the wound. Finally, release the handle to remove the stapler.

[0004] However, some patients may have physiological adhesion between the inner plate skin and the glans penis. Directly placing the glans protection rod between the inner plate skin and the glans penis may easily damage the glans penis and may also cause bleeding in the adhesion area. Summary of the Invention

[0043] Example 1:

[0044] See also Figure 1-9 The present invention provides a technical solution: a skin cutting device after hydroseparation of the inner and outer plate skin, comprising a stapler 1, wherein the stapler 1 comprises a glans protection rod 2, one end of which is adapted to the glans penis, and the glans protection rod 2 is provided with a first groove 3 for transporting physiological saline solution, and the first groove 3 extends along the length direction of the glans protection rod 2, and the glans protection rod 2 is provided with a water outlet 4 at the port at one end for contacting the inner plate skin, and a push assembly 19 for pushing physiological saline solution to the water outlet 4 is slidably connected in the first groove 3.

[0045] In this solution: the stapler 1 comprises a housing 14 made of medical plastic for accommodating internal components;

[0046] It also includes a circular cutting knife 15 located on the inner side of the front end of the stapler, which completes the circular cutting of the inner plate skin by pressing action to ensure a neat incision;

[0047] The invention also includes a stapler cartridge 16 storing a plurality of staples, which automatically staples the inner skin and outer skin mucosa together during cutting, replacing traditional suturing.

[0048] It also includes a handle 18, which is pressed by the doctor to trigger the cutting and stapling actions simultaneously;

[0049] It also includes an adjusting knob 17 for fixing the housing 14 and the glans protection rod 2.

[0050] Working principle and usage:

[0051] Step 1: Place the glans protection rod 2 on the surface of the glans, and gradually cover the glans protection rod 2 with the inner skin.

[0052] Step 2: As the inner plate skin gradually covers the glans protection rod 2, the injection assembly 19 is pushed to deliver the saline solution to the water outlet 4 through the first groove 3, and the saline solution penetrates into the gap between the inner plate skin and the glans.

[0053] Step 4: Use the adjustment knob 17 to adjust the housing 14 and the glans protection rod 2 to the set position and lock them.

[0054] Step 5: Trigger the handle 18 , and the annular cutting knife 15 cuts from the outer skin to the inner skin, while the staples in the staple cartridge 16 close the wound.

[0055] Step 6: Loosen the handle 18 and remove the stapler 1.

[0056] Compared to existing technologies, the water outlet 4 and first groove 3 on the glans protection rod 2 form a fluid channel. The injection assembly 19 propels the flow of saline solution, separating the inner skin from the glans mucosa. The saline solution then fills the space between the glans and the inner skin, lubricating the glans protection rod 2. Compared to simply placing the glans protection rod 2 on the glans surface and allowing the inner skin to cover the end of the rod 2 near the glans, this reduces damage to the glans and the likelihood of bleeding in the adhesion area.

[0057] In this embodiment: the end of the glans protection rod 2 that is used to contact the inner plate skin is provided with a second groove 5 for recovering physiological saline, and the second groove 5 extends along the length direction of the glans protection rod 2.

[0058] In this solution, a second groove 5 for recovering physiological saline solution is provided at one end of the glans protection rod 2 for contacting the inner plate skin, and the second groove 5 extends along the length direction of the glans protection rod 2 .

[0059] The second groove 5 and the water outlet 4 form a circulation system. While injecting normal saline, the second groove 5 recovers excess normal saline to reduce fluid accumulation, keep the surgical field clear, and prevent normal saline from continuing to be injected between the glans and the inner plate skin after the shell 14 and the glans protection rod 2 are fixed, thereby reducing the probability of tearing the connection between the glans and the inner plate skin after the inner plate skin bulges, and reducing the error caused by the bulging of the inner plate skin during circumcision.

[0060] In this embodiment: a guide groove 6 is provided on the inner side wall of the glans protection rod 2 which is used to contact the skin of the inner plate, and the guide groove 6 is connected to the second groove 5.

[0061] In this solution: a guide groove 6 is opened on the inner wall of the end of the glans protection rod 2 that contacts the inner plate skin, and the guide groove 6 is connected to the second groove 5.

[0062] The guide groove 6 fits the curved surface of the glans penis, and after the physiological saline flows out of the water outlet 4, it is guided to the second groove 5 for recovery through the guide groove 6. The physiological saline recovery path is optimized and the retention of physiological saline is reduced.

[0063] In this embodiment, the injection assembly 19 includes a first piston block 7 slidably connected to the first groove 3 and a push rod 8 fixedly connected to the first piston block 7 . The first piston block 7 is sealed in the first groove 3 .

[0064] In this solution, the first piston block 7 is slidably connected in the first groove 3 , the push rod 8 is fixedly connected to the first piston block 7 , and the fixed sealing ring on the first piston block 7 is in sealing cooperation with the first groove 3 .

[0065] The first piston block 7 provides stable pressure, and the push rod 8 is manually pushed to drive the first piston block 7 to squeeze the physiological saline to the water outlet 4, ensuring uniform output of the physiological saline.

[0066] In this embodiment, a second piston block 9 is slidably connected in the second groove 5 , the second piston block 9 is sealed with the second groove 5 , and a pull rope 10 is fixedly connected between the second piston block 9 and the first piston block 7 .

[0067] In this solution, the second piston block 9 is slidably connected in the second groove 5 , the second piston block 9 is fixedly connected to the sealing ring and sealed in the second groove 5 , and the pull rope 10 is fixedly connected between the second piston block 9 and the first piston block 7 .

[0068] The double-piston linkage design allows the pull rope 10 to pull the second piston block 9 synchronously when the first piston block 7 is pushed, forming a negative pressure in the second groove 5 to absorb excess saline between the inner plate skin and the glans penis, so that the injection and recovery are completed synchronously, and the saline in the area between the glans penis and the inner plate skin is in a balanced state, avoiding local edema.

[0069] In this embodiment, the glans protection rod 2 is made of transparent material.

[0070] In this solution, the glans protection rod 2 is made of a transparent material. The position of the glans and the flow of saline solution can be observed through the rod 2. During the placement of the rod 2, the excess saline solution or bleeding between the glans and the inner skin can be detected in a timely manner, thereby reducing the risk of damage to sensitive areas such as the frenulum due to misoperation.

[0071] In this embodiment, there are multiple water outlet holes 4 , and the multiple water outlet holes 4 are evenly distributed circumferentially around the central axis of the glans protection rod 2 .

[0072] In this solution: by designing the number of the water outlet holes 4 to be multiple, the multiple water outlet holes 4 are evenly distributed circumferentially around the central axis of the glans protection rod 2.

[0073] The multiple water outlet holes 4 spray physiological saline at the same time, and the physiological saline can cover the entire inner wall of the inner plate skin more quickly, so that the physiological saline is evenly injected into the gap between the inner plate skin and the glans penis.

[0074] In this embodiment: multiple water outlet holes 4 are slidably connected with corresponding plugs 11, and an elastic support component 12 is fixedly connected between multiple plugs 11 and the glans protection rod 2. When the elastic support component 12 is in a naturally stretched state, multiple plugs 11 respectively block the corresponding water outlet holes 4.

[0075] In this solution: multiple water outlet holes 4 are slidably connected to corresponding plugs 11, multiple plugs 11 are fixedly connected to the glans protection rod 2 with an elastic support component 12, and the elastic support component 12 is in a naturally stretched state, and multiple plugs 11 respectively block the corresponding water outlet holes 4.

[0076] When the push assembly 19 does not push the saline in the first groove 3, the elastic support assembly 12 is in a naturally extended state, and the multiple plugs 11 respectively block the corresponding water outlet holes 4. The closure of the plugs 11 reduces the probability of contamination of the saline and reduces the leakage of the saline, and reduces the reflux of the saline after flowing out of the water outlet hole 4 into the first groove 3.

[0077] When the push assembly 19 pushes the physiological saline in the first groove 3 , the elastic support assembly 12 is in a stretched state, and the plurality of plugs 11 are separated from the corresponding water outlets 4 , and the physiological saline flows out from the plurality of water outlets 4 in one direction.

[0078] In this embodiment: the elastic support component 12 includes a tension spring 13, and the two ends of the tension spring 13 are fixedly connected to the glans protection rod 2 and the corresponding plug 11 respectively. When the tension spring 13 is in a naturally stretched state, the multiple plugs 11 respectively block the corresponding water outlet holes 4.

[0079] In this embodiment, the ends of the tension spring 13 are fixedly connected to the glans protection rod 2 and the corresponding plugs 11, respectively. When the tension spring 13 is in its naturally extended state, the plugs 11 respectively block the corresponding water outlets 4. The elastic support component 12 can also be a pull rope 10. Since the tension spring 13 is more stable than the pull rope 10, it is preferred.

[0080] When the push assembly 19 does not push the physiological saline in the first groove 3, the tension spring 13 is in a naturally extended state, and the multiple plugs 11 respectively block the corresponding water outlet holes 4. The closure of the plugs 11 reduces the probability of the physiological saline being contaminated and reduces the leakage of the physiological saline, and reduces the physiological saline flowing out of the water outlet 4 from flowing back into the first groove 3.

[0081] When the push assembly 19 pushes the physiological saline in the first groove 3 , the tension spring 13 is in a stretched state, and the plurality of plugs 11 are separated from the corresponding water outlet holes 4 , and the physiological saline flows out from the plurality of water outlet holes 4 in one direction.

[0082] Example 2:

[0083] See also Figure 10 The present invention provides a technical solution: a method for using a skin cutting device after water separation of the inner and outer skin plates, comprising a skin cutting device after water separation of the inner and outer skin plates,

[0084] Step 1: Place the glans protection rod 2 on the glans surface, and gradually cover the glans protection rod 2 with the inner skin;

[0085] Step 2: As the inner plate skin gradually covers the glans protection rod 2, the push rod 8 and the first piston block 7 are pushed to push the saline solution to the water outlet 4, and the saline solution penetrates into the gap between the glans and the inner plate skin through the multiple water outlet holes 4.

[0086] Step 3: In the process of pushing the push rod 8 and the first piston block 7, the second piston block 9 is pulled by the pull rope 10 to form a negative pressure environment in the second groove 5, and the excess saline between the glans and the inner plate skin flows through the guide groove 6 into the second groove 5.

[0087] Step 4: Use the adjustment knob 17 to adjust the housing 14 and the glans protection rod 2 to the set position and lock them.

[0088] Step 5: Trigger the handle 18 , and the annular cutting knife 15 cuts from the outer skin to the inner skin, while the staples in the staple cartridge 16 close the wound.

[0089] Step 6: Loosen the handle 18 and remove the stapler 1.

[0090] Technical effect: In steps 2 and 3, the push rod 8 and the pull rope 10 are linked to realize the single-step completion of "water injection-separation-recovery", shortening the operation time (traditional method requires repeated flushing and suction).

[0091] The negative pressure suction of the second piston block 9 matches the push pressure to avoid secondary damage to the mucosa caused by excessive suction, especially the thin and tender tissue of pediatric patients.

[0092] The transparent glans protection rod 2 allows the surgeon to monitor the entire process from step one to step four, ensuring that the inner skin completely covers the glans protection rod 2 without distortion, thereby reducing the risk of postoperative asymmetry.

[0093] Physiological saline separation replaces violent stripping, significantly reducing intraoperative bleeding; the closed-loop recovery system avoids fluid residue and reduces postoperative edema and infection rates.

[0094] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
