[0075] Before describing the embodiments of the present application in detail, the application scenarios provided by the embodiments of the present application are first introduced.

[0076] Incision protection sleeves are commonly used medical devices in surgery. In surgical operations that require pre-incision (such as small heart incision surgery), doctors usually use incision protection sleeves, that is, incision protection sleeves are placed at the incision to avoid incision infection and damage caused by excessive traction. At the same time, the incision protection sleeve can also prevent incision bleeding, thereby avoiding interference with the doctor's surgical field. The doctor can insert surgical instruments through the incision protection sleeve set at the incision to perform surgical operations.

[0077] In the above process, due to the small incision, the operation is performed in a narrow field of view, and the cavity cannot obtain the illumination light outside the cavity, so doctors often use the endoscope system to illuminate and obtain surgical field information, thereby guiding the operation. However, in some operations with smaller incisions (such as mitral valve replacement), the distance between the surgical incision and the affected part is short, and the lens of a conventional endoscope is long, so it is impossible to use a conventional endoscope to extend through the incision.

[0078] In some related technologies, doctors usually make a new incision next to the surgical incision and insert an endoscope through the new incision to provide lighting. Since the viewing angle of the endoscope is not the doctor's frontal viewing angle during surgery, the lighting function provided by the endoscope is difficult to meet the doctor's usage needs.

[0079] In order to solve the problem that the lighting function provided by the endoscope cannot meet the doctor's needs, in other related technologies, doctors usually wear headlights to directly illuminate the surgical incision to obtain a visual field of the affected part. Since the operation time is generally long, the doctor needs to keep his head and the patient's incision in a fixed position for a long time, which creates a heavy burden for the doctor.

[0080] In order to meet the lighting needs and avoid placing a heavy burden on doctors, some related technologies will add a lighting function to the incision protection cover, but the structure of the incision protection cover needs to be modified, which affects the normal surgical process and is not convenient for clinical use.

[0081] Based on the above considerations, in order to provide surgical field illumination within the incision and meet clinical use requirements, the inventor of the present application has designed an auxiliary device that can be detachably connected to the incision protection cover and includes a controllable light source after in-depth research. In such an auxiliary device, since the auxiliary device is detachably connected to the incision protection cover, it is possible to provide surgical field illumination within the incision without changing the structure of the incision protection cover. In this process, there is no change to the structure of the incision protection cover, which will not affect the normal surgical process and will not cause a burden on the doctor, thereby meeting the needs of clinical use.

[0082] The auxiliary device provided in the embodiment of the present application is described below in conjunction with relevant drawings.

[0083] It should be noted that the auxiliary device provided in the embodiment of the present application can be used not only for a fixed-height incision protective cover, but also for a variable-height incision protective cover. It can be set according to actual usage requirements, and the embodiment of the present application does not impose specific restrictions on this.

[0084] Figure 1 It shows a schematic structural diagram of an incision protection cover 20 in one embodiment of the present application; Figure 2A schematic diagram of a three-dimensional structure of the auxiliary device 10 connected to the incision protection cover 20 in a first viewing angle in an embodiment of the present application is shown; Figure 3 A schematic diagram of a three-dimensional structure of the auxiliary device 10 connected to the incision protection cover 20 at a second viewing angle in an embodiment of the present application is shown; for ease of explanation, only the part related to the embodiment of the present application is shown.

[0085] It should be noted that, for the auxiliary device 10, Figure 2 The first perspective in the game is a top-down stereoscopic perspective. Figure 3 The second perspective is an upward stereoscopic perspective.

[0086] In some embodiments, please refer to Figure 1 The incision protection sleeve 20 includes a protection sleeve body 21, an outer ring 22 and an insertion ring 23. A channel p is provided in the protection sleeve body 21, and the outer ring 22 and the insertion ring 23 are provided at both ends of the protection sleeve body 21 along the first direction F1. The outer ring 22 is used to abut against the outside of the incision, and the insertion ring 23 is used to extend into the incision. Please refer to Figure 2 and Figure 3 The auxiliary device 10 provided in the embodiment of the present application includes a base 100, a plurality of light sources 200 and a control unit 300. The base 100 is detachably connected to the insertion ring 23 of the incision protection cover 20. An opening k adapted to the channel p of the incision protection cover 20 is provided on the base 100 along the first direction F1, and the base 100 has a first side s1 and a second side s2 arranged opposite to each other along the first direction F1. All the light sources 200 are arranged on the second side s2 of the base 100. The control unit 300 is electrically connected to the light source 200, and is used to control the light source 200 to be turned on or off.

[0087] Therefore, according to the structural characteristics of the incision protection cover 20, since the base 100 is detachably connected to the insertion ring 23 of the incision protection cover 20, when the incision protection cover 20 is set at the incision, the base 100 will extend into the incision together with the insertion ring 23. A controllable light source 200 is arranged on the base 100, and the light source 200 can be turned on or off under the control of the control unit 300, so that after the base 100 follows the insertion ring 23 into the incision, the light source 200 on the base 100 can provide surgical field illumination into the cavity, thereby providing the doctor with surgical field information in the front view direction, so that there is no need to use endoscope illumination by wearing a headlamp or opening a new incision from the side. Since the base 100 is detachably connected to the insertion ring 23 of the incision protection cover 20, the structure of the incision protection cover 20 itself will not be changed, and the normal surgical process will not be affected. At the same time, the auxiliary device 10 can be reused to reduce the use cost. Therefore, the auxiliary device 10 for the incision protection cover 20 provided in the embodiment of the present application can provide lighting for the surgical field within the incision without affecting the normal surgical process as much as possible, reduce the doctor's intraoperative load requirements, and meet the doctor's usage needs.

[0088] In some embodiments, please refer to Figure 3 , and refer to the following instructions Figure 6 , all the light sources 200 arranged on the second side s2 of the base 100 can be arranged around the edge of the opening k of the base 100. Optionally, all the light sources 200 can be arranged evenly and symmetrically. Of course, the light sources 200 can also be arranged unevenly. The number of light sources 200 can be 8, 12, 24 or other numbers. The arrangement and number of the light sources 200 can be set according to specific usage requirements, and the embodiments of the present application do not impose specific restrictions on this.

[0089] In this way, since multiple light sources 200 are provided, it is possible to further avoid the shielding of the illumination of the single light source 200 by instruments during surgery, so that the doctor can better obtain the surgical field information during surgery and improve the success rate of the surgery.

[0090] Figure 4 A schematic cross-sectional view of the connection between the auxiliary device 10 and the incision protection cover 20 in a third viewing angle in an embodiment of the present application is shown; Figure 5 Shows Figure 4 A schematic diagram of the local enlarged structure at point A in the middle; Figure 6 A schematic structural diagram of the auxiliary device 10 connected to the incision protection cover 20 at a fourth viewing angle in an embodiment of the present application is shown; for ease of explanation, only the part related to the embodiment of the present application is shown.

[0091] It should be noted that, for the auxiliary device 10, Figure 4 The first perspective in the video is the frontal perspective. Figure 6The fourth perspective in the game is the upward perspective.

[0092] In some embodiments, please refer to Figures 4 to 6 , and join the reference Figure 2 , a clamping groove 101 is provided on the first side s1 of the base 100. The clamping groove 101 is configured to be detachably engaged with the insertion ring 23. That is, the insertion ring 23 can enter the clamping groove 101 from the first side s1 of the base 100 and be detachably engaged with the clamping groove 101. Thus, by configuring the structure of the clamping groove 101 on the base 100, the base 100 and the insertion ring 23 can be detachably connected.

[0093] Figure 7 A schematic diagram of the three-dimensional structure of a base 100 in an embodiment of the present application is shown; Figure 8 A schematic cross-sectional structure diagram of a base 100 in an embodiment of the present application is shown; for ease of explanation, only the portion related to the embodiment of the present application is shown.

[0094] For specific embodiments, please refer to Figure 7 and Figure 8 , and combined with reference Figure 4 and Figure 5 , the slot of the card slot 101 has an inner edge c1 and an outer edge c2 surrounding the inner edge c1. It can be understood that the inner edge c1 of the card slot 101 is arranged around the opening k of the base 100. The inner edge c1 of the card slot 101 and the outer edge c2 of the card slot 101 are relative to the center of the base 100. The inner edge c1 of the card slot 101 is closer to the center of the base 100 than the outer edge c2 of the card slot 101. The plane where the inner edge c1 of the card slot 101 is located is defined as the first plane P1, and the plane where the outer edge c2 of the card slot 101 is located is defined as the second plane P2. The first plane P1 and the second plane P2 coincide with each other. That is, when the insertion ring 23 is installed in the card slot 101, the insertion ring 23 can enter the card slot 101 along the first direction F1.

[0096] It should be noted that, for the auxiliary device 10, Fig. 9 The first perspective in the game is a top-down stereoscopic perspective. Fig.10 The second perspective is the normal perspective.

[0097] For more details about other embodiments, please refer to Figures 9 to 13 , the first plane P1 where the inner edge c1 of the slot 101 is located and the second plane P2 where the outer edge c2 of the slot 101 is located are parallel to each other and have a gap g. That is, when the insertion ring 23 is installed in the slot 101, the insertion ring 23 can enter the slot 101 along a direction inclined to the first direction F1. Optionally, as Fig.12 and Fig.13 As shown, the inner edge c1 of the card slot 101 is closer to the second side s2 of the base 100 than the outer edge c2 of the card slot 101. Of course, the outer edge c2 of the card slot 101 may also be closer to the second side s2 of the base 100 than the inner edge c1 of the card slot 101. As long as the first plane P1 where the inner edge c1 of the card slot 101 is located and the second plane P2 where the outer edge c2 of the card slot 101 is located are parallel to each other and have a gap g in the first direction F1, the embodiment of the present application does not impose any specific limitation on this.

[0098] Therefore, the specific structural form of the card slot 101 can be flexibly set in combination with actual use requirements, as long as the insertion ring 23 can be detachably connected to the card slot 101, and the embodiment of the present application does not impose specific restrictions on this.

[0100] It should be noted that, for the auxiliary device 10, Fig.14 The first perspective in the game is a top-down stereoscopic perspective. Fig.15 The second perspective in the game is a stereoscopic perspective looking up. Fig.16 The third perspective in the film is the normal perspective. Fig.18 The fourth perspective in the game is the upward perspective. Figures 14 to 16FIG. 2 shows an incision protective cover 20 having a different shape from that in some of the aforementioned embodiments. It can be understood that Figures 14 to 18 The auxiliary device 10 shown in the figure can also be used in the incision protection cover 20 shown in some of the above embodiments, and the auxiliary device 10 shown in some of the above embodiments can also be used in Figures 14 to 18 The incision protection cover 20 shown in the figure. Fig.23 , you can also understand it in this way, so I won’t go into details.

[0101] In some embodiments, please refer to Figures 14 to 18 The base 100 includes a first base body 110 and a second base body 120 arranged in sequence along a first direction F1. The first base body 110 and the second base body 120 are provided with a sub-opening k1 along the first direction F1 (which can be combined with the schematic diagram shown below). Fig.21 ), the two sub-openings k1 together constitute the opening k. That is, the base 100 is composed of two parts, the first base body 110 and the second base body 120. The first side s1 of the base 100 is formed on the side of the first base body 110 away from the second base body 120, and the second side s2 of the base 100 is formed on the side of the second base body 120 away from the first base body 110.

[0102] The auxiliary device 10 further includes a first adsorbent 410 disposed on the first base 110 and a second adsorbent 420 disposed on the second base 120. The first adsorbent 410 and the second adsorbent 420 can attract each other. When the first base 110 and the second base 120 are connected, a ring 23 can be sandwiched between the first base 110 and the second base 120.

[0103] That is, the first base body 110 and the second base body 120 can be detachably connected together by means of the first adsorption member 410 and the second adsorption member 420 that can attract each other. The first adsorption member 410 can be set in the first base body 110 in an embedded form, and the second adsorption member 420 can also be set in the second base body 120 in an embedded form. Optionally, the adsorption force generated by the mutual attraction between the first adsorption member 410 and the second adsorption member 420 can be a magnetic force. In this case, the first adsorption member 410 and the second adsorption member 420 can be configured as magnetic members.

[0104] Therefore, by configuring the base 100 to be a first base body 110 and a second base body 120 that can be detachably connected together by adsorption force, the insertion ring 23 can be clamped between the first base body 110 and the second base body 120, thereby achieving a detachable connection between the base 100 and the insertion ring 23.

[0106] It should be noted that, for the auxiliary device 10, Fig.19 The first state of the middle base 100 refers to the state in which the first base body 110 and the second base body 120 are connected. Fig. 20 and Fig.21 The second state of the middle base 100 refers to a state in which the first base body 110 and the second base body 120 are separated.

[0107] In some embodiments, please refer to Figures 19 to 22 At least one of the sides of the first seat body 110 and the second seat body 120 facing each other is provided with a groove x. The groove x is used to accommodate at least a portion of the insertion ring 23.

[0108] It can be understood that “at least one of the sides of the first base body 110 and the second base body 120 facing each other is provided with a groove x” includes the following situations: (1) the side of the first base body 110 facing the second base body 120 is provided with a groove x; (2) the side of the second base body 120 facing the first base body 110 is provided with a groove x; (3) the side of the first base body 110 facing the second base body 120 and the side of the second base body 120 facing the first base body 110 are both provided with a groove x. When the first base body 110 and the second base body 120 are connected, the insertion ring 23 can be positioned between the first base body 110 and the second base body 120 by means of the groove x, and fixed between the first base body 110 and the second base body 120 by means of the adsorption force generated between the first base body 110 and the second base body 120.

[0109] Please continue to refer to Fig. 20 and Fig.21 Optionally, a plurality of first adsorbents 410 and second adsorbents 420 may be provided, and the first adsorbents 410 may be arranged around the edge of the sub-opening k1 of the first seat body 110, and the second adsorbents 420 may be arranged around the edge of the sub-opening k1 of the second seat body 120. It is understandable that all the first adsorbents 410 may be arranged evenly or unevenly, and all the second adsorbents 420 may be arranged evenly or unevenly, as long as the detachable connection between the first seat body 110 and the second seat body 120 is satisfied, and the embodiment of the present application does not impose any specific limitation on this.

[0110] Fig.23A schematic diagram of a three-dimensional structure in which an auxiliary device 10 is connected to an incision protection cover 20 in another embodiment of the present application is shown; Fig.24 A schematic structural diagram showing a connection between the base 100 and the insertion ring 23 in another embodiment of the present application is shown; Fig.25 A schematic structural diagram of a fixing member 500 in yet another embodiment of the present application is shown; for ease of explanation, only the portion related to the embodiment of the present application is shown.

[0111] Please refer to Figure 23 to Figure 25 In some embodiments, the auxiliary device 10 further includes a plurality of fixing members 500. The fixing members 500 are configured to have fixing grooves 501 for clamping and fixing the insertion ring 23 and the base 100. Therefore, the insertion ring 23 and the base 100 can be clamped and fixed together by the fixing members 500, so as to realize a detachable connection between the base 100 and the insertion ring 23.

[0112] Alternatively, if Fig.23 and Fig.24 As shown, four fixing members 500 may be provided. Of course, the number of fixing members 500 may be set according to actual use requirements, and the embodiment of the present application does not impose any specific limitation on this.

[0113] It can be understood that in some of the aforementioned embodiments, in some implementations where the base 100 and the insertion ring 23 are detachably connected through the card slot 101 or the cooperation between the first adsorption component 410 and the second adsorption component 420, a fixing component 500 can also be used for further fixing, which can be selected according to actual usage conditions, and the embodiments of the present application do not impose specific restrictions on this.

[0114] Therefore, through the detachable structural form between the base 100 and the insertion ring 23 involved in some of the above embodiments, the relevant structure can be flexibly set up, as long as the detachable connection between the base 100 and the insertion ring 23 can be achieved, and the embodiments of the present application do not impose specific restrictions on this.

[0115] In some embodiments, the base 100 is made of a soft material. Figure 5 , Figure 7 and Figure 8 For example, during the process of installing the insert ring 23 into the card slot 101, the insert ring 23 is installed into the card slot 101 along the first direction F1. During this process, the card slot 101 will deform and increase until the insert ring 23 is completely inserted into the card slot 101. Figures 11 to 13 For example, when the insertion ring 23 is installed into the card slot 101, the inner edge c1 of the card slot 101 can be compressed first, and then the insertion ring 23 contacts the card slot 101 until the insertion ring 23 completely enters the card slot 101. In other words, the base 100 can be made of a soft material to facilitate the detachable connection between the insertion ring 23 and the base 101.

[0116] Optionally, the material of the base 100 includes silicone or thermoplastic polyurethane elastomer. In this way, the base 100 can have better biocompatibility and improve the safety and stability of the auxiliary device 10.

[0117] In some embodiments, the control unit 300 is further configured to be able to periodically adjust the current of each light source 200. That is, the heating state of each light source 200 under a specific current can be tested in advance, and the control unit 300 can adjust each light source 200 according to the test results. Specifically, since the greater the current passing through the light source 200, the greater the heat generated by the light source 200, in this way, the current of each light source 200 can be periodically changed to control the heat generated by each light source 200 while meeting the lighting required during use, thereby avoiding potential harm to the patient.

[0118] It is understandable that periodic regulation refers to adjusting the current of the light source 200 according to the time rule for each light source 200. The current of the light source 200 can be gradually increased and then gradually decreased within a preset time, or the current of the light source 200 can be maintained at one value for a period of time and maintained at another value for another period of time. The specific law of periodic regulation can be set according to actual use, and the embodiment of the present application does not impose specific restrictions on this. That is, at any time, the current of some light sources 200 is lowered, and the heat generation is reduced, and the current of some light sources 200 is increased, and the heat generation is increased.

[0119] It should be noted that the method of how the control unit 300 performs periodic adjustment of the current of the light source 200 is a prior art and is not the focus of the present application, and will not be described in detail here.

[0120] In other embodiments, the auxiliary device 10 further includes a plurality of temperature detection members disposed in the base 100. The temperature detection members are electrically connected to the control unit 300 for detecting the temperature at the location of the temperature detection members. The control unit 300 is further configured to adjust the electrical parameters of the corresponding light source 200 according to the temperature detected by the temperature detection members. The electrical parameters include at least one of current and voltage.

[0121] Due to the different areas of contact with the external environment and human tissue, different areas on the base 100 have different heat dissipation, and the temperature detection element can transmit the temperature information of different positions to the control unit 300. When the local temperature is higher than the allowed threshold (such as 35 degrees Celsius), the control unit 300 can automatically reduce the current of the light source 200 in the area, thereby reducing the temperature of the light source 200 to avoid potential harm to the patient. At the same time, the control unit 300 can appropriately increase the current of the light source 200 in the area with higher heat dissipation efficiency to compensate for the overall lighting effect to meet the use requirements during surgery.

[0122] It should be noted that the method of how the control unit 300 adjusts the current or voltage of the light source 200 according to the temperature detected by the temperature detection element is a prior art and is not the focus of this case, and will not be described in detail here.

[0123] For specific embodiments, please refer to Figure 6 and Fig.18 , there are multiple light sources 200, and they are evenly arranged around the edge of the opening k of the base 100. The temperature detection member can be set to correspond to the light source 200 one by one, or it may not correspond to the light source 200 one by one, as long as the temperature in the required area can be detected. Of course, the light sources 200 can also be unevenly arranged. One temperature detection member can be set between adjacent light sources 200, or two temperature detection members or other numbers of temperature detection members can be set. The arrangement of the light source 200 and the temperature detection member can be set according to specific use requirements, and the embodiments of the present application do not impose specific restrictions on this.

[0124] In some embodiments, please refer to Figure 2 and Figure 3 , and combined with reference Fig. 9 , Fig.14 , Fig.15 and Fig.23 The control unit 300 includes a power supply 310 and a controller 320 which are electrically connected to the light source 200 respectively. The controller 320 is electrically connected to the power supply 310, and the controller 320 is configured to control the power supply 310 to adjust the electrical parameters of the light source 200. The electrical parameters include at least one of current and voltage. Optionally, the power supply 310 can use a storage battery or a dry cell. The light source 200 can be electrically connected to the power supply 310 and the controller 320 respectively by means of wires 330. The wires 330 of all the light sources 200 are in the base 100, and can be gathered to an outlet on the base 100 and connected to the power supply 310 and the controller 320.

[0125] It should be noted that the electric wire 330 can be disposed in the channel p of the incision protection cover 20 , or can be disposed outside the channel p of the incision protection cover 20 . Figure 2 , Figure 3 , Fig. 9 , Fig.14 , Fig.15 and Fig.23 Schematically shows that the wire 330 is arranged in the channel p of the incision protection cover 20. The arrangement of the wire 330 can be arranged according to the actual use situation, and the embodiment of the present application does not impose any specific restrictions on this. Specifically, a protective structure can be arranged outside the wire 330, and the protective structure is made of a material with better biocompatibility such as a thermoplastic polyurethane elastomer to further improve the safety and stability of the overall structure.

[0126] It can be understood that, in order to facilitate the description of the contents of some of the aforementioned embodiments, the wires 330 are omitted in some other diagrams shown in some of the aforementioned embodiments.

[0127] Therefore, the controller 320 can control the power supply 310 to adjust the electrical parameters of the light source 200, and then control the light intensity and temperature of the light source 200 to meet different surgical procedures and user requirements.

[0128] In some embodiments, the controller 320 may also be configured to display the current battery power and, based on the current power consumption of the light source 200 , display the duration that can support lighting.

[0129] Therefore, through the adjustment form of the control unit 300 illustrated in some of the above embodiments, the control unit 300 can be flexibly configured according to different operations and doctors' usage requirements, which can not only meet personalized usage requirements, but also adjust the temperature of all light sources 200 to be within the safe temperature of the operation to avoid scalding the patient's tissue during the operation.

[0130] In summary, in the auxiliary device 10 provided in the embodiment of the present application, by providing a base 100 that is detachably connected to the insertion ring 23 of the incision protection cover 20, and by providing a controllable light source 200 on the base 100, it is possible to provide lighting function from the patient's surgical incision site to the cavity, thereby providing the doctor with surgical field information in the frontal direction, without the doctor having to wear a headlamp during the operation, or using an endoscope from the side to provide lighting. The base 100 is detachably connected to the insertion ring 23, and can be used in combination with different incision protection covers 20 to avoid affecting the existing surgical process, thereby improving the versatility of the auxiliary device 10. Since a plurality of light sources 200 are provided on the second side s2 of the base 100, the illumination of the plurality of light sources 200 can avoid the shielding of the single light source 200 provided by a traditional headlamp or endoscope by the intraoperative instrument, and further enables the doctor to obtain surgical field information throughout the operation, thereby improving the success rate of the operation. The control unit 300 and the temperature detection element in the auxiliary device 10 can be flexibly configured to adjust the electrical parameters of the light source 200, and then adjust the brightness, temperature, etc. of the light source 200. It can not only control the total heat generated by all light sources 200 to avoid scalding the patient's tissue during surgery, but also meet different surgical needs and the doctor's personal preferences to achieve personalized adjustment of surgical lighting. Therefore, the auxiliary device 10 provided in the embodiment of the present application can provide lighting for the surgical field in the incision without affecting the doctor's normal surgical process as much as possible, reduce the intraoperative load requirements for the doctor, and meet clinical use needs.

[0131] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0132] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
