Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a skin expansion and isolation device for surgery. Background Art

[0002] With the advancement of minimally invasive surgery, laparoscopy is increasingly replacing open surgery as the preferred method in clinical practice. Currently, skin dilators, also known as incision protectors, are widely used during surgery. Existing incision protectors in hospitals only serve to protect the skin incision wound and provide some retraction to expand the field of view. While they offer some advantages in pneumoperitoneum-free surgeries, their exposed opening can lead to loss of pneumoperitoneum during pneumoperitoneum surgery, necessitating re-establishment of pneumoperitoneum for continued laparoscopic procedures.

[0003] To solve this type of pneumoperitoneum problem clinically, an end cover is usually added to the protective cover, such as the incision protector described in Invention Publication No. CN211022982U. A through hole for inserting a poke card is reserved on the end cover, and the end cover is clipped onto the protective cover. The pneumoperitoneum is re-established by inflating the incision through the poke card. However, during actual operation, as the pneumoperitoneum pressure in the incision increases, the end cover often separates from the protective cover and bounces off the protective cover, affecting the normal progress of the operation. Summary of the Invention

[0004] In order to solve the above technical problems, the purpose of the present invention is to provide a skin expansion and isolation device for surgery, which solves the problem that the existing skin expander delays the progress of the operation due to the easy popping of the end cap, and provides a skin expander that can maintain pneumoperitoneum during surgery.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a skin expansion and isolation device for surgery, whose main body is configured as a skin expander, and the skin expander is extended to the surrounding with a protective film, the protective film and the skin expander are integrally formed, the protective film is in contact with the patient's skin, a stamp card is placed in the skin expander, and the protective film is connected to the stamp card through a seal.

[0006] By adopting the above technical solution, a protective film is integrally formed on the outside of the skin expander. The protective film can be spread flat on the surface of the patient's skin, filling the gap between the skin expander and the patient's skin, further isolating the incision, and preventing contaminated blood from seeping into the patient's incision through the gap during surgery, thereby improving the sealing effect between the skin expander and the incision. When pneumoperitoneum needs to be established, a puncture card is inserted into the skin expander. After cleaning and disinfecting the protective film, the protective film can be folded up and fixed to the puncture card using a seal. Since the protective film and the skin expander are integrally formed, the two are not easy to separate. This structure replaces the end cover and can also be used to maintain pneumoperitoneum.

[0007] Preferably, the skin expander is provided with an outer ring and an insertion ring, and a thin film channel is provided between the outer ring and the insertion ring.

[0008] By adopting the above technical solution, the insertion ring in the skin expander is inserted into the abdominal wall and abuts against the inner wall of the abdominal wall, the film channel is placed in the incision and contacts the incision, the outer ring abuts against the outer surface of the abdominal wall, and the film channel is pulled by rolling the outer ring. Under the support of the outer ring and the insertion ring, the film channel abuts against the skin incision and gradually expands the incision to facilitate subsequent surgery.

[0009] Preferably, the protective film is integrally formed on the inner ring.

[0010] By adopting the above technical solution, since the outer ring is used to abut the outer surface of the skin incision, the protective film is connected to the outer ring to prevent the protective film from entering the skin incision.

[0011] Preferably, the protective film is integrally formed on the film channel.

[0012] By adopting the above technical solution, the thin film channel is integrally formed on the protective film, which can prevent the protective film from being rolled along with the outer ring and affecting the fit between the protective film and the patient's skin.

[0013] Preferably, the sealing member is fixedly connected to the protective film.

[0014] By adopting the above technical solution, the sealing member is connected to the protective film, thereby avoiding loss during surgery due to the large number of surgical instruments and the small size of the sealing member.

[0015] Preferably, the sealing member is configured as an open ring.

[0016] By adopting the above technical solution, the open ring has a simple structure and is easy to clamp.

[0017] Preferably, the sealing member includes a baffle, which is hinged to the open ring. The baffle is configured as an arc-shaped structure. A locking member is provided at the end of the baffle, and the locking member is connected to the end of the open ring.

[0018] By adopting the above technical solution, after the open ring is clamped on the puncture card, the baffle is connected to the open ring under the action of the limit rod, blocking the open ring and further fixing the protective film on the puncture card. The arc-shaped contour of the baffle is used to make the baffle completely fit the side wall of the puncture card, thereby avoiding air leakage at the baffle position.

[0019] Preferably, a developable module is provided in the open ring.

[0020] By adopting the above technical solution, when the open ring is lost, the developable module can be used to determine whether the open ring has fallen into the patient's body, thereby reducing the patient's anxiety.

[0021] Preferably, the sealing member is configured as a cable tie.

[0022] By adopting the above technical solution, the sealing member in the form of a cable tie is more convenient to purchase.

[0023] Preferably, the cable tie includes a lock buckle, and a pull rod is connected to the cable tie. The pull rod is located on the lock buckle and is cooperatively connected to the cable tie.

[0024] By adopting the above technical solution, the pull rod is used to drive the lock buckle on the cable tie to move, so that the lock buckle is in a separated state, which makes it easier to loosen the cable tie and saves more effort.

[0025] Compared with the prior art, the advantages of the present invention are: (1) by extending the protective film around the skin expander, the protective film is applied to the outside of the patient's abdominal wall to improve the airtightness of the connection between the skin expander and the patient's incision. In addition, after the protective film is folded up, it can be tied to the puncture card using a seal, replacing the end cover commonly used in surgery, solving the problem of the end cover being bounced open. The protective film here has the practical effect of two usage states; (2) the seal is set as an open ring, and a baffle is hinged on the open ring. The baffle is set as an arc structure. The arc-shaped baffle blocks the open ring, which can further strengthen the connection between the protective film and the puncture card; (3) the developable module in the open ring is used to determine whether the open ring is left in the patient's body in the event of loss.

[0033] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0034] Example 1

[0035] like Figures 1 to 4 The illustrated surgical skin expansion and isolation device comprises a skin expander 1, which includes an outer ring 110, an insertion ring 120, and a thin film channel 130. The outer ring 110 and the insertion ring 120 are respectively connected to the ends of the thin film channel 130. The insertion ring 120 is placed on the inner side of the abdominal wall and abuts against the inner abdominal wall, while the outer ring 110 abuts against the outer surface of the patient's abdominal wall. When the outer ring 110 is rolled, the thin film channel 130 is pulled and rolled up. Supported by the outer ring 110 and the insertion ring 120, the thin film channel 130 abuts against the patient's skin incision and gradually expands the incision. The skin expander 1 in this embodiment is conventional and will not be described in detail here.

[0036] The skin expander 1 has a protective film 2 extending outwards, and the protective film 2 is integrally formed with the skin expander 1. Figure 2 As shown, the protective film 2 is laid flat on the outer surface of the patient's abdominal wall, which is one of the usage states of the protective film 2. Because there is a gap between the outer ring 110 of the skin expander 1 and the patient's skin, contaminated blood can seep into the incision through the gap during surgery. This, especially blood containing cancer cells, can lead to incomplete surgical treatment and even spread to other areas, posing a significant safety risk. Therefore, the protective film 2 connected to the skin expander 1 can isolate the incision, eliminating the gap between the outer ring 110 and the incision, preventing contaminated blood from seeping into the incision, and thus improving the seal between the skin expander 1 and the incision.

[0037] Specifically, the protective film 2 is integrally formed on the insertion ring 120, that is, the protective film 2 is connected to the insertion ring 120. Since the insertion ring 120 is thicker than the thin film channel 130, it is easy to connect the protective film 2 to the insertion ring 120 and it is not easy to fall off. In addition, it can also prevent the protective film 2 from rolling up with the outer ring 110 and affecting the fit between the protective film 2 and the patient's skin.

[0038] like Figure 1 As shown, when pneumoperitoneum needs to be re-established, the punch card 3 is inserted into the skin dilator 1, while the protective film 2 is retracted and secured to the punch card 3 using a seal. This represents another use of the protective film 2. The punch card 3 inflates the interior, replacing the end cap and preventing it from popping open. Furthermore, because the protective film 2 is integrally formed with the skin dilator 1, the connection between the two is stronger. Furthermore, the area of ​​action of air pressure on the protective film 2 is larger than that of the end cap, which reduces the effect of air pressure on the protective film 2.

[0039] It should be noted that before the protective film 2 is folded up, the surface of the protective film 2 needs to be cleaned and disinfected to prevent contaminants on the protective film 2 from entering the abdominal wall through the film channel 130 .

[0040] In summary, the protective film 2 is given two uses.

[0041] In this embodiment, the protective film 2 is connected to the punch card 3 through a sealing member. The sealing member is configured as an open ring 4. The open ring 4 is connected to the punch card 3 through its own open end. The operation is convenient and the structure is simple.

[0042] The sealing member is fixedly connected to the protective film 2 , that is, the open ring 4 is connected to the protective film 2 . The open ring 4 is connected to the protective film 2 by adhesive or other fixing members, thereby reducing the probability of the open ring 4 being lost.

[0043] The open ring 4 is preferably but not limited to a plastic ring. The plastic ring here has a certain elastic deformation so that it can be better attached to the stamp card 3.

[0044] A developing module is provided in the open ring 4. The developing module is preferably but not limited to a metal wire. The metal wire is embedded in the open ring 4 to solve the problem that in the event that the open ring 4 is lost, medical staff can judge whether the open ring 4 is placed in the patient's abdomen based on the metal wire and medical scanning equipment, such as a CT machine.

[0045] The sealing member is provided with a baffle 5, one end of which is hinged to the open ring 4. The baffle 5 is provided with an arc-shaped structure, and a locking member is provided at the end of the baffle 5. The baffle 5 is connected to the open ring 4 through the locking member to achieve sealing and closure of the open ring 4 and fix the protective film 2 on the stamp card 3; and the baffle 5 utilizes its arc-shaped structure to fully fit the arc-shaped contour of the stamp card 3, further improving the overall airtightness.

[0046] The openable and closable ends of the open ring 4 and the baffle 5 are arranged as follows: Figure 3 and Figure 4 The structure shown allows the open ring 4 and the baffle 5 to be assembled into a complete fixed ring. The locking member is arranged at the openable and closable ends of the open ring 4 and the baffle 5. The locking member includes a limiting hole 6 and a limiting block 7. The limiting block 7 is plugged into the limiting hole 6. The limiting block 7 and the limiting hole 6 are respectively provided on the two contact surfaces of the open ring 4 or the baffle 5. The structure is simple and the production cost is low.

[0047] There are at least two pairs of limit blocks 7 and limit holes 6. This embodiment is described by taking two pairs of locking members as an example. Figure 3 and Figure 4 It can be seen that when the limiting holes 6 of one pair of locking parts are set on the open ring 4, the limiting holes 6 of the other pair of locking parts are opened on the baffle 5. Such a cross setting can further enhance the connection strength between the open ring 4 and the baffle 5.

[0048] Further, such as Figure 3 or Figure 4 As shown, a number of limiting holes 6 are opened along the arc-shaped side wall of the open ring 4. By changing the position of the limiting rod 7 in the limiting hole 6, the position of the baffle 5 can be adjusted, and then the space between the baffle 5 and the open ring 4 is adjusted, so that it can be suitable for the clamping and fixation of stamps 3 of different diameters, thereby improving the application range of this open ring 4.

[0049] Example 2

[0050] This embodiment is different from the embodiment 1 in that the sealing member is provided as a cable tie 8 , and the cable tie 8 realizes the connection between the protective film 2 and the puncture card 3 .

[0051] The cable tie 8 is passed through the protective film 2 to achieve the connection between the cable tie 8 and the protective film 2 .

[0052] Furthermore, the cable tie 8 includes a lock buckle 810, a pull rod 9 is provided at the lock buckle 810, the pull rod 9 is connected with the lock buckle 810, and the lock buckle 810 uses the cooperation of the latch 811 and the slot 812 to realize the locking of the cable tie 8, the latch 811 is connected to the lock buckle 810, and one end of the pull rod 9 is fixed with the latch 811. Figure 5 and Figure 6 As shown, the other end of the pull rod 9 passes through the lock buckle 810 and extends outside the lock buckle 810, and the pull rod 9 can move relative to the lock buckle 810. When the locking state of the cable tie 8 needs to be released, it is only necessary to pull the pull rod 9 outward to separate the locking teeth 811 and the locking groove 812 into the shape shown in FIG. Figure 6 The state shown is sufficient, and this structure makes it easier to loosen the cable tie 8.

[0053] Example 3

[0054] This embodiment differs from Example 1 in that the protective film 2 is integrally formed on the film channel 130. Because the outer ring 110 needs to be rolled during use of the skin expander 1, the protective film 2 is connected to the film channel 130 to prevent the protective film 2 from rolling up with the outer ring 110 and affecting its fit with the patient's skin. It should be noted that to prevent the film channel 130 from being affected by the outer ring 110, the protective film 2 can be connected to the lower middle portion of the film channel 130.

[0055] Example 4

[0056] This embodiment is different from the embodiment in that the protective film 2 is integrally formed on the outer ring 110, that is, the protective film 2 is connected to the outer ring 110. Since the outer ring 110 is used to abut the outer surface of the skin incision, connecting the protective film 2 to the outer ring 110 can prevent the protective film 2 from entering the skin incision and causing friction damage to it.

[0057] Although the preferred embodiments of the present invention have been described in detail above, it should be clearly understood that various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are intended to be included within the scope of protection of the present invention.
