Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a protective device based on clinical thyroid surgery. Background Art

[0002] Clinically, when doctors encounter patients who need thyroid surgery, they usually adopt oral vestibule / submental laparoscopic thyroid surgery, which involves creating a cavity under the patient's skin through the oral vestibule and / or submental area, and then performing various types of surgical treatments on the thyroid gland through endoscopic surgery.

[0003] During the operation, doctors usually do not have special equipment to protect the patient's skin, so when the doctor operates the trocar for treatment, the trocar is prone to friction, squeezing and pulling the patient's skin, causing damage to the patient's skin during the operation and causing secondary injury.

[0004] In the prior art, doctors usually place gauze at the corners of the patient's mouth, and then use adhesive tape to stick the gauze to the skin outside the patient's mouth. However, it is difficult to fix the gauze on the inside of the patient's mouth due to the influence of saliva secretion. Therefore, with this operation method, the gauze is easily displaced or even falls off as the operation proceeds, and the reliability is poor. Summary of the invention

[0011] In some embodiments, the main body is provided with an operation hole, which passes through the skin-friendly layer and the anti-ulcer dressing layer; the operation hole is used to cover the operation channel established by the doctor under the chin of the patient.

[0012] In some embodiments, the apertures of the operation holes gradually decrease along the direction from the skin-friendly layer to the anti-ulcer dressing layer.

[0013] In some embodiments, the second protective member further includes an auxiliary fixing portion, which is disposed at at least one end of the main body along the first direction, and is used to be fixed under the chin of the patient.

[0031] Please refer to Figures 1 to 4 The present invention proposes a protective device 100 based on thyroid surgery clinical practice, which includes two symmetrically arranged first protective members 10 and a connecting member 20, wherein the first protective member 10 includes a first clamping portion 11, a second clamping portion 12 and a flexible connecting portion 13, the first clamping portion 11 and the second clamping portion 12 are spaced apart along a first direction X to form a clamping space 101, the flexible connecting portion 13 connects the first clamping portion 11 and the second clamping portion 12, and is located on the side of the two first protective members 10 close to each other; the two ends of the connecting member 20 are respectively connected to the first clamping portions 11 of the two first protective members 10; the two first protective members 10 are respectively used to be clamped and fixed at the corners of the patient's mouth on both sides, and the connecting member 20 is used to cooperate with the two first protective members 10 to be fixed under the patient's chin.

[0032] The protective device 100 based on clinical thyroid surgery is applied to clinical thyroid surgery to provide protection for the patient's skin when the doctor performs surgery on the patient, thereby reducing the risk of secondary injury to the patient during the operation.

[0033] The first protective member 10 is used to protect the corners of the patient's mouth. That is, when performing transoral vestibular / submental laparoscopic thyroid surgery, the doctor usually needs to control the patient to lie on his back and keep his mouth open, so that the doctor can pass the trocar through the mouth to reach the thyroid gland. When the doctor controls the trocar, it is easy to rub and pull against the skin at the corners of the patient's mouth, which can easily tear the corners of the mouth and cause unnecessary secondary damage to the patient.

[0034] It should be noted that the trocar described in these embodiments of the present invention actually refers to the trocar and the endoscope used in conjunction with the trocar. The trocar is used to isolate a stable area in the patient's body for the endoscope to move or operate in. When performing surgery, doctors mainly use endoscopes to observe and treat the patient's diseased parts, and when operating the endoscope, it is inevitable that the external trocar will move.

[0035] In these embodiments of the present invention, the doctor can place two first protective members 10 at the two corners of the patient's mouth before inserting the trocar into the oral cavity, thereby reducing the probability of direct contact between the trocar and the patient's skin when the doctor is performing treatment operations, and reducing the probability of pulling and friction at the corners of the patient's mouth, thereby providing protection for the patient during the operation.

[0036] The first protective member 10 includes a first clamping portion 11, a second clamping portion 12 and a flexible connecting portion 13, wherein the first clamping portion 11 and the second clamping portion 12 are components used for clamping and fixing in the first protective member 10, and the flexible connecting portion 13 connects the first clamping portion 11 and the second clamping portion 12, and is located on the side of the two first protective members 10 close to each other, so that the two first protective members 10 form two clamping devices with openings "facing outward". When in use, the doctor can apply pressure in the spacing direction of the two first protective members 10 to cause the connecting member 20 to undergo elastic deformation, thereby reducing the spacing between the two first protective members 10, and loosen the two first protective members 10 after bringing them close to the two corners of the patient's mouth, so that the connecting member 20 can be used to drive the two first protective members 10 to rebound to both sides, thereby clamping into the lip sides of the two corners of the patient's mouth.

[0037] The first clamping portion 11 and the second clamping portion 12 are spaced apart along the first direction X to form a clamping space 101, so that the clamping space 101 can be used to accommodate the skin at the corners of the patient's mouth. At this time, the flexible connecting portion 13 can be in a state of abutting and fitting with the lip side of the corner of the patient's mouth, so as to isolate the trocar from the skin at the corners of the patient's mouth during subsequent surgical treatment, thereby reducing the pulling and friction of the trocar on the skin at the corners of the patient's mouth.

[0038] It should be noted that the flexible connection part 13 is a component that can undergo elastic deformation and has a certain degree of flexibility, so that the distance between the first clamping part 11 and the second clamping part 12 can be finely adjusted according to the thickness of the patient's lips; at the same time, since the flexible connection part 13 has a certain degree of flexibility, it can also deform itself when it comes into contact with the trocar, thereby reducing interference with the doctor's operation of the trocar and reducing the impact on the doctor's surgical treatment operations, and having higher reliability.

[0039] That is, in these embodiments of the present invention, by providing a flexible connection portion 13 between the first clamping portion 11 and the second clamping portion 12, on the one hand, the flexible connection portion 13 can be used to isolate the trocar needle operated by the doctor during surgical treatment, thereby reducing the probability of the trocar needle causing secondary injury to the patient; on the other hand, the first protective member 10 itself has a certain degree of adjustable performance, which can adapt to the thickness of the corners of the mouth and lips of different patients and reduce interference with the doctor's operation.

[0040] The connection method between the flexible connection part 13 and the first clamping part 11 and the second clamping part 12 can be a fixed connection method such as gluing, injection molding, etc., so as to enhance the structural consistency between the flexible connection part 13 and the first clamping part 11 and the second clamping part 12; or, in some embodiments, the flexible connection part 13 and the first clamping part 11 and the second clamping part 12 can be arranged to be detachably connected by means of a slot, a buckle, etc., so as to replace or select the shape of the first clamping part 11 and the second clamping part 12 according to the face shape of different patients.

[0041] The two ends of the connecting piece 20 are respectively connected to the first clamping parts 11 of the two first protective pieces 10. A possible implementation method is that the first clamping part 11 is a component that is clamped on the outside of the skin at the corners of the patient's mouth. At this time, the connecting piece 20 is respectively connected to the first clamping parts 11 of the two first protective pieces 10, which can further improve the structural consistency and completeness of the two first protective pieces 10 and reduce the risk of loss of the complete set of first protective pieces 10 during storage and transportation.

[0042] The connecting piece 20 is used to cooperate with the two first protective pieces 10 to be fixed under the chin of the patient, which means that in these embodiments of the present invention, in addition to maintaining the completeness of the first protective pieces 10 when the protective device 100 based on the clinical thyroid surgery is in the stored state, the connecting piece 20 can also, when the protective device 100 based on the clinical thyroid surgery is in the working state, allow the doctor to place the two first protective pieces 10 into the corners of the patient's mouth respectively, and then clamp the connecting piece 20 under the patient's chin to cooperate with the two first protective pieces 10 to form a stable placement state, thereby further reducing the risk of loosening and displacement of the two first protective pieces 10 during surgical treatment, and providing higher reliability.

[0043] A possible implementation of the connection between the connecting piece 20 and the first clamping portion 11 is that the connecting piece 20 can be fixedly connected to the first clamping portion 11 by gluing, integral molding, etc.; or, the connecting piece 20 can also be detachably connected by means of a slot, a buckle, Velcro, etc., so that a more suitable connecting piece 20 can be replaced according to the length from the corner of the patient's mouth to the chin, thereby achieving better adaptability.

[0044] In some embodiments of the present invention, the connecting member 20 can be configured to be wide-band shaped to reduce the possibility of causing injury to the patient due to pulling when the connecting member 20 is clamped under the patient's chin, thereby improving reliability.

[0045] In some embodiments of the present invention, the connecting piece 20 can be made of an elastic stretchable material so that during the installation and placement stage of the protective device 100 based on clinical thyroid surgery, after the doctor inserts the first protective piece 10 into the patient's mouth, the connecting piece 20 is stretched to deform the connecting piece 20, and then the end of the connecting piece 20 away from the first protective piece 10 is clamped to the position under the patient's chin and then released, and the protective device 100 based on clinical thyroid surgery is installed and fastened by utilizing the rebound characteristics of the connecting piece 20 and the first protective piece 10.

[0046] According to the clinical protection device 100 based on thyroid surgery provided by the present invention, by setting the first protection piece 10 including the first clamping part 11, the second clamping part 12 and the flexible connecting part 13, the doctor can place the first protection piece 10 at the corner of the patient's mouth before performing surgical treatment on the patient, and utilize the elasticity of the flexible connecting part 13 to enable the first clamping part 11 and the second clamping part 12 to apply a certain clamping pressure on the lips at the corner of the patient's mouth, thereby improving the stability of the first protection piece 10 after prevention; at the same time, the setting of the flexible connecting part 13 can also isolate the direct contact between the lip side at the corner of the patient's mouth and the trocar, thereby reducing the possibility of secondary injury to the patient during surgical treatment, and the flexible connecting part 13 can reduce the impact on the doctor's operation of the trocar, which is beneficial to improving the doctor's control performance of the equipment and having better reliability.

[0047] In some embodiments, the first protection member 10 extends along an arc along a cross section perpendicular to the first direction X.

[0048] That is to say, in these embodiments of the present invention, any cross-section of the first protective member 10 perpendicular to the first direction X extends along an arc, so that the boundary line shape of one first protective member 10 close to another first protective member 10 and the boundary line shape away from another first protective member 10 are both arcs, and the opening directions are opposite.

[0049] This arrangement can make the first protective piece 10 more compatible with the shape of the patient's mouth corner, thereby reducing the difficulty of placing the first protective piece 10 and improving the patient's comfort after placing the first protective piece 10. At the same time, this arrangement is also conducive to improving the fit between the lip side of the patient's mouth corner and the flexible connection part 13, so that the patient's mouth corner is more naturally opened during the placement of the first protective piece 10, which is conducive to keeping the patient's mouth open.

[0050] In some embodiments, an orthographic projection of the second clamping portion 12 along the first direction X falls within the first clamping portion 11 .

[0051] It means that the cross-sectional area of ​​the second clamping portion 12 perpendicular to the first direction X is not larger than the cross-sectional area of ​​the first clamping portion 11 perpendicular to the first direction X. In these embodiments of the present invention, since the second clamping portion 12 is a component placed inside the patient's mouth, the smaller cross-sectional area can adapt to the environment inside the patient's mouth, facilitating the placement of the first protective member 10.

[0052] In this way, the portion of the first clamping portion 11 that overlaps with the second clamping portion 12 in the first direction X is the portion actually used for clamping, and the portion of the first clamping portion 11 that is misaligned with the second clamping portion 12 in the first direction X can also further increase the contact area between the first clamping portion 11 and the skin outside the patient's oral cavity, thereby improving the stability and reliability of the first protective member 10 after installation.

[0053] In some embodiments, the first protection member 10 further includes an extension portion 14 , which is connected to a side of the second clamping portion 12 that is away from the flexible connection portion 13 .

[0054] The extension portion 14 is connected to the side of the second clamping portion 12 away from the flexible connection portion 13, so as to improve the clamping and fixing effect of the second clamping portion 12. It can be understood that in these embodiments of the present invention, the orthographic projection of the extension portion 14 along the first direction X can also fall within the first clamping portion 11, that is, in the first direction X, a clamping space 101 can also be formed between the extension portion 14 and the first clamping portion 11, so as to cooperate with the second clamping portion 12 to achieve the clamping and fixing of the first protective member 10.

[0055] The extension portion 14 can be arranged at the center of the second clamping portion 12, that is, the extension portion 14 can be arranged in a shape extending along an arc formed by a cross section of the second clamping portion 12 perpendicular to the first direction X, and the center of the arc segment is close to one side of the protruding direction of the arc segment. Such a setting will not increase the volume of the second clamping portion 12 during placement, so that the second clamping portion 12 and the extension portion 14 can be smoothly placed in the patient's mouth. At the same time, after being placed in the patient's mouth, the extension portion 14 can adapt to the environment inside the patient's mouth, reduce the pulling of the lip muscles, and increase the area of ​​contact with the skin inside the patient's mouth, thereby improving the clamping and fixing strength of the first protective member 10 inside the patient's mouth, and reducing the risk of loosening and displacement of the first protective member 10 during surgery.

[0056] In some embodiments, it can be arranged that the distance between the second clamping portion 12 and the first clamping portion 11 gradually increases along the direction from one end where the second clamping portion 12 and the flexible connecting portion 13 are connected to the other end, so as to adapt to the gradual increase in the thickness of the patient's oral lips, thereby further improving the degree of fit between the first protective member 10 and the patient after placement, and further reducing the risk of the patient being pinched due to prolonged surgery.

[0057] Correspondingly, a natural transition may be provided between the surface of the extension portion 14 close to the first clamping portion 11 and the surface of the second clamping portion 12 close to the first clamping portion 11 , and the distance between the extension portion 14 and the first clamping portion 11 also tends to gradually increase.

[0058] In these embodiments of the present invention, the thickness of the second clamping portion 12 and the extension portion 14 can be gradually reduced, thereby achieving a gradual increase in the distance between the second clamping portion 12 and the extension portion 14 and the first clamping portion 11; or, in some embodiments, the second clamping portion 12 and the extension portion 14 can be formed into a structure with a certain curvature during the molding stage, so that the distance between the second clamping portion 12 and the extension portion 14 and the first clamping portion 11 gradually increases in the direction from one end where the second clamping portion 12 and the flexible connecting portion 13 are connected to the other end.

[0059] The connection between the extension portion 14 and the second clamping portion 12 can also adopt a detachable connection method such as a snap, a slot, a plug-in, a magnet, etc. to adapt to the oral size of different patients, so that the doctor can choose whether to install the extension portion 14 according to the actual size of the patient's oral cavity; or, the extension portion 14 and the second clamping portion 12 can be fixedly connected by bonding or integral molding to improve the structural consistency between the extension portion 14 and the second clamping portion 12.

[0060] In some embodiments, the protective device 100 based on clinical thyroid surgery also includes a second protective member 30, which is arranged on the connecting member 20 and includes a main body 31, and the main body 31 includes a stacked skin-friendly layer 311 and an anti-ulcer dressing layer 312, the skin-friendly layer 311 is used to contact the patient's subchin skin, and a plurality of water-absorbing blind holes 103 are provided on the surface of the skin-friendly layer 311 away from the anti-ulcer dressing layer 312.

[0061] The second protective member 30 is arranged on the connecting member 20 and includes a main body portion 31, which means that the second protective member 30 is connected to the connecting member 20, so that the connecting member 20 not only cooperates with the first protective member 10 to improve the installation stability of the protective device 100 based on clinical thyroid surgery, but also has the function of the second protective member 30 to provide protection for the patient under the chin.

[0062] The second protective member 30 is arranged on the connecting member 20. A possible implementation method is that the connecting member 20 is a complete rope-like structure, and its two ends are respectively connected to the first clamping parts 11 of the two first protective members 10, and the second protective member 30 is provided with a connecting structure sleeved on the periphery of the connecting member 20, so that the second protective member 30 can be relatively displaced with the connecting member 20 to adjust the position of the second protective member 30 on the connecting member 20; or, in some embodiments, the second protective member 30 and the connecting member 20 can also be fixedly connected by gluing, integral molding, etc. to improve the structural consistency between the second protective member 30 and the connecting member 20.

[0063] The main body 31 is the structural body of the second protective member 30 , and is the portion that actually contacts the patient's subchin skin during operation of the protective device 100 based on clinical thyroid surgery, so as to cooperate with the first protective member 10 to achieve the placement and positioning of the protective device 100 based on clinical thyroid surgery.

[0064] In these embodiments of the present invention, the main body 31 may be, but is not limited to, configured to be in a plate shape or a block shape.

[0065] It should be noted that when the doctor performs submental laparoscopic thyroid surgery on the patient, the patient often takes a supine position. After the doctor establishes an operating channel under the patient's chin, the doctor inserts the cannula needle into the patient's thyroid position through the operating channel. At this time, since the outer wall of the cannula needle is a hard structure, when the doctor is operating, the cannula needle located outside the operating channel will be in contact with the patient's submental skin for a long time, which can easily cause the patient's submental skin to be damaged after being squeezed and rubbed, and even form pressure sores.

[0066] In these embodiments of the present invention, the main body 31 includes a skin-friendly layer 311 and an anti-ulcer dressing layer 312 which are stacked together, wherein the skin-friendly layer 311 is used to contact the patient's subchin skin, and the anti-ulcer dressing layer 312 serves to isolate the patient's skin from the trocar needle, thereby reducing the squeezing and friction effect of the trocar needle on the patient's subchin skin, thereby achieving a protective function.

[0067] Exemplarily, in these embodiments of the present invention, the anti-ulcer dressing layer 312 may be, but is not limited to, configured to use soft silicone foam dressings, polyurethane film dressings, hydrogel dressings, honey-containing dressings, iodine-containing dressings, etc., to reduce the pressure of the cannula needle on the patient's skin under the chin when the doctor operates the cannula needle, thereby reducing the risk of pressure sores in the patient's pressure area and providing greater reliability.

[0068] The surface of the skin-friendly layer 311 facing away from the anti-ulcer dressing layer 312 is provided with a plurality of water-absorbing blind holes 103, so as to absorb moisture under the chin of the patient by using the water-absorbing blind holes 103, thereby reducing the risk of the second protective member 30 sliding and shifting after being placed. It should be noted that in these embodiments of the present invention, since the skin-friendly layer 311 is the structure in the second protective member 30 that directly contacts the patient's skin, during the operation, due to the adhesion of the second protective member 30, the part of the patient's chin covered by the second protective member 30 is prone to sweat. After the sweat accumulates, it will affect the adhesion effect between the second protective member 30 and the patient's skin, and then the position of the second protective member 30 will shift with the trocar when the doctor operates the trocar, affecting the protection effect.

[0069] Based on this, a plurality of water-absorbing blind holes 103 are set on the surface of the skin-friendly layer 311 away from the anti-ulcer dressing layer 312, and the sweat produced by the patient's skin is absorbed by the plurality of water-absorbing blind holes 103 to keep the skin-friendly layer 311 and the patient's skin relatively dry, thereby reducing the risk of positional displacement of the second protective component 30 under the action of the trocar, and improving reliability.

[0070] In some embodiments, the main body 31 is provided with an operation hole 102, which passes through the skin-friendly layer 311 and the anti-ulcer dressing layer 312; the operation hole 102 is used to cover the operation channel established by the doctor under the chin of the patient.

[0071] The main body 31 is provided with an operation hole 102, and the operation hole 102 is used to cover the operation channel established by the doctor under the chin of the patient. The doctor establishes the operation channel under the chin of the patient, which means that the doctor makes an incision in the patient's oral vestibule and subchin to establish a channel to the patient's thyroid position, and then performs the operation by inserting a trocar. In this way, there is also a risk that the doctor will rub and pull the skin under the chin of the patient when operating the trocar, causing the patient's skin to be damaged again.

[0072] That is to say, the difference from the aforementioned embodiments is that, in these embodiments of the present invention, during the installation and placement stage of the second protective member 30, the main body 31 needs to cover the operating channel established by the doctor under the patient's chin, and the second protective member 30 is utilized to reduce the pulling and friction of the skin around the operating channel by the doctor when operating the trocar, thereby further reducing the risk of secondary injury to the patient.

[0073] It should be noted that in these embodiments of the present invention, since the second protective member 30 needs to cover the operating channel under the patient's chin, the anti-ulcer dressing layer 312 can be, but is not limited to, provided with calcium alginate dressings, soft silicone foam dressings, silver-containing dressings, etc., to absorb the exudate at the wound formed in the operating channel, thereby improving the exudate management capability of the second protective member 30, and being able to effectively prevent wound infection and reduce the risk of ulcers at the surgical site.

[0074] In these embodiments of the present invention, by covering the operating channel established by the doctor under the chin of the patient with the operating hole 102, on the one hand, the second protective member 30 can be used to stabilize the skin near the operating channel established under the chin of the patient, and the protective device 100 based on the clinical practice of thyroid surgery can be installed firmly in cooperation with the connecting member 20, thereby reducing the risk of loosening and displacement of the protective device 100 based on the clinical practice of thyroid surgery during the operation; on the other hand, the doctor can insert the operating device (trocar) into the operating channel established under the chin of the patient through the operating hole 102, and use the operating hole 102 to limit the trocar, thereby alleviating the friction and pulling effect on the skin under the chin of the patient when the doctor operates the trocar, thereby reducing secondary injury to the patient during the operation.

[0075] In some embodiments, the aperture of the operation hole 102 gradually decreases along the direction from the skin-friendly layer 311 to the anti-sore dressing layer 312 .

[0076] Along the direction from the skin-friendly layer 311 to the anti-sore dressing layer 312, the aperture of the operation hole 102 gradually decreases, that is, in these embodiments of the present invention, the operation hole 102 can be set to be a frustum.

[0077] On the side of the main body 31 close to the patient's skin, the aperture of the operation hole 102 is larger than the aperture on the side of the main body 31 away from the patient's skin, which is beneficial for the doctor to install the second protective component 30 and reduces the probability that the main body 31 covers the position where an operation channel is established under the patient's chin; at the same time, on the side of the operation hole 102 away from the patient's skin, the smaller aperture of the operation hole 102 can also achieve a better trocar limiting effect. When the doctor operates the trocar with large movements, the operation hole 102 will be pulled first, thereby reminding the doctor to adjust the operation and reduce the risk of secondary injury to the patient.

[0078] It should be noted that, in these embodiments of the present invention, the aperture of the operating hole 102 can be selected according to the size of the practical trocar, but it is necessary to ensure that the minimum aperture of the operating hole 102 is larger than the maximum outer diameter of the trocar, so as to ensure that when the doctor operates the trocar, the trocar can always remain in a state of being able to move in the internal space of the operating hole 102 without adhering to the hole wall of the operating hole 102 (it means that when the aperture is too small, the trocar will have an interference fit with the hole wall of the operating hole 102 after insertion, so that the relative position of the trocar and the hole wall of the operating hole 102 is fixed. At this time, when the doctor operates the trocar to perform the operation, it is equivalent to "stirring" the trocar, thereby reducing the protective effect of the second protective member 30 on the patient).

[0079] The aperture sizes at both ends of the operation hole 102 in the thickness direction and the maximum diameter size of the trocar can be set to reduce the probability of the above phenomenon. For example, the minimum aperture size of the operation hole 102 can be set to 2 to 5 times the maximum aperture size of the operation hole 102, but is not limited to, and the minimum aperture size of the operation hole 102 is set to 1.5 to 2 times the maximum diameter size of the trocar used.

[0080] In some embodiments, the main body 31 can also be made of transparent elastic materials such as thermoplastic elastomer (TPE) and thermoplastic polyurethane elastomer (TPU), so that the doctor can observe the contact between the cannula needle and the patient's skin when operating the cannula needle, which is beneficial for the doctor to adjust his own operation and further reduce the risk of secondary injury to the patient.

[0081] In some embodiments, the second protective member 30 further includes an auxiliary fixing portion 32 , which is disposed at at least one end of the main body portion 31 along the first direction X, and is used to be fixed under the chin of the patient.

[0082] The auxiliary fixing portion 32 is used to assist in fixing the main body 31 under the chin of the patient.

[0083] Since the patient's skin area covered by the main body 31 is the area where the doctor establishes the operation channel, and there is a wound on the skin area, if the main body 31 is strongly connected to this area of ​​the patient, when the main body 31 is removed after the operation is completed, the part (the location where the operation channel is established) may be injured due to pulling.

[0084] In the embodiments of the present application, the auxiliary fixing portion 32 is disposed at at least one end of the main body portion 31 along the first direction X, and the auxiliary fixing portion 32 is used to fix the main body portion 31 under the chin of the patient. In this way, the position where the second protective piece 30 is connected to the patient can be transferred to a position away from the operating channel. During the installation and placement stage of the protective device 100 based on the clinical thyroid surgery, the main body 31 can cover the periphery of the operating channel, and the main body 31 can be made to abut the skin around the operating channel without setting a strong connection. Then, by fixing the auxiliary fixing part 32 to the peripheral skin of the patient, the installation connection strength between the second protective piece 30 and the patient's skin is improved, and the stability of the second protective piece 30 during the operation is improved; and during the disassembly stage of the second protective piece 30 after the operation is completed, the auxiliary fixing part 32 can be removed first, and the main body 31 can be used to stabilize the patient's skin around the operating channel to reduce the probability of pulling the skin around the operating channel. After the auxiliary fixing part 32 is removed, the main body 31 can be removed, which can improve the stability of the second protective piece 30 during the operation while minimizing the risk of secondary injury to the patient by the second protective piece 30 during the disassembly process.

[0085] For example, in these embodiments of the present invention, two auxiliary fixing parts 32 may be provided, and the two auxiliary fixing parts 32 are respectively provided on opposite sides of the main body part 31. At this time, during the installation of the second protective member 30, one auxiliary fixing part 32 may be installed to the skin between the patient's chin and the oral vestibule, and the other auxiliary fixing part 32 may be installed to the patient's neck, and then the connection part 20 is used to limit the freedom of movement of the main body part 31 toward the periphery after installation, thereby further improving the structural stability of the second protective member 30 during surgery.

[0086] In some embodiments, the auxiliary fixing part 32 is provided with an adhesive layer (not shown) on the surface thereof for fixing to the chin of the patient, and the auxiliary fixing part 32 is used to bond to the chin of the patient. The bonding method is simple and reliable, which is conducive to improving the efficiency of installation and removal of the protection device 100 based on thyroid surgery clinical practice, and has higher reliability.

[0087] In some embodiments, the flexible connection portion 13 is a silicone member or a rubber member; at least one of the first clamping portion 11 and the second clamping portion 12 is a silicone member or a rubber member.

[0088] In these embodiments of the present invention, the flexible connection part 13 is configured as a silicone member or a rubber member, so that the flexible connection part 13 has a certain flexible resilience to meet the need for angle adjustment between the first clamping part 11 and the second clamping part 12. At the same time, the flexible connection part 13 can better limit the operation of the trocar, remind the doctor to change the operation method, and reduce secondary damage to the patient.

[0089] At least one of the first clamping part 11 and the second clamping part 12 is a silicone member or a rubber member, so that the first clamping part 11 and the second clamping part 12 can reduce the damage to the patient caused by clamping under the premise of obtaining a good clamping and fixing force. In other words, when one of the first clamping part 11 and the second clamping part 12 is a silicone member or a rubber member, in the process of clamping the oral lips of the patient together with the other, the elasticity of the flexible connection part 13 will clamp the oral lips of the patient together with the other. At the same time, in the clamping process, because it has a certain resilience, it will have good contact with the patient's skin, and then deform to adapt to the shape of the patient's skin, so as not to cooperate with the other to clamp the patient.

[0090] Preferably, in these embodiments of the present invention, the second clamping portion 12 may be configured as a silicone member to cooperate with the first clamping portion 11 on the inner side of the patient's oral cavity to achieve a good fixing effect of the first protective member 10 .

[0091] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
