Description

Technical Field

[0001] This invention relates to the field of medical device accessories, and in particular to an incision protective sleeve with a light source control box. Background Technology

[0002] Currently, in single-port laparoscopic surgery, the incision protector typically consists of a top cover and a thin membrane channel connected to the bottom of the top cover. When using such an incision protector, the lack of space between the membrane channel and the top cover during surgery means that instrument movement relies solely on rotating the flexible top cover to deform it. This inevitably results in insufficient surgical space, inflexible operation, difficulty in observing instrument entry and exit, and a high risk of instrument interference. Furthermore, single-port laparoscopic surgery is performed in an airtight space; if surgical smoke is not promptly removed, it can easily affect the surgical field of vision. Although a smoke exhaust vent can be installed on the top cover, it is too far from the area where the smoke-generating surgical instruments are located, resulting in poor smoke extraction. In addition, single-port laparoscopic surgery is an internal procedure, with only the endoscope's LED light providing illumination, making the entire surgical environment insufficiently bright. Moreover, all products are disposable, leading to high costs for surgical instruments.

[0003] Current laparoscopic trocars consist of a light source control box, an incision protective sleeve, and a multi-channel assembly. Their advantages include an external power supply for improved convenience and the ability to establish a pneumoperitoneum environment and facilitate smoke extraction. The disadvantages are that the light source control box is a disposable product, cannot be disassembled and reused, and results in high costs.

[0004] On the other hand, existing protective sleeves generally provide functions such as negative pressure suction to remove smoke and lighting, but each time they are connected to the light source control box, the connectors of each function need to be connected separately, which is inconvenient to use. Summary of the Invention

[0005] The purpose of this invention is to provide an incision protective sleeve with a light source control box, which ensures the reusability of the light source control box by setting replaceable consumables, thereby reducing the economic burden on patients.

[0006] On the other hand, it enables quick connection between the light source control box and the incision protective sleeve, improving surgical efficiency.

[0007] A cut-out protective sleeve with a light source control box, comprising a light source control box and a cut-out protective sleeve, which are connected to each other, wherein the light source control box is provided with a filter assembly, characterized in that the filter assembly is a replaceable filter assembly, which is disposed in a cavity provided in the light source control box, and the cavity is sealed with a main unit back cover 152.

[0008] The replaceable filter assembly includes,

[0009] The filter box cover 11 is provided with an upper connecting connector 12 for connecting to the cut protective sleeve 3;

[0010] The filter box lower cover 13 is provided with a lower connecting joint 14 for connection to a negative pressure device; and

[0011] The filter element 15 has a filter material in the middle and sealing rings 151 on both sides of the filter material that cooperate with the upper cover 11 and the lower cover 13 of the filter box.

[0012] The filter element 15 has a back cover 152 connected to the main unit, so that when the main unit is disassembled and the filter material is replaced, the filter element 15 can be replaced by reinstalling the main unit back cover 152.

[0013] Compared with previous technologies, the beneficial effects of the present invention are as follows:

[0014] 1. This invention has a built-in replaceable filter assembly. The entire filter assembly can be removed by disassembling the back cover and replaced with a new filter element assembly, enabling the invention to be used repeatedly.

[0015] 2. The built-in battery of this invention is a lithium battery and it is equipped with a charging port, which can be charged and discharged normally, enabling repeated use of this invention.

[0016] 3. The third substrate and the upper connecting joint are adjacent, which ensures the quick connection between the present invention and the cut-out protective sleeve, and the easy disassembly design also ensures the repeated use of the present invention.

[0017] 4. The lower retaining ring of the cut protective sleeve body is connected to a multi-cavity connecting tube. By placing the pipes and lines corresponding to each function into the multi-cavity connecting tube, and then inserting it into the light source control box with one click, the connection of multiple interfaces can be completed in one step, improving the convenience of use.

Detailed Implementation

[0029] The present invention will now be described in detail with reference to the accompanying drawings:

[0030] like Figure 1-7 As shown: A cut-out protective sleeve with a light source control box, which includes a light source control box and a cut-out protective sleeve, and the two are connected to each other. The light source control box is provided with a filter component. The filter component is a replaceable filter component, which is disposed in a cavity provided in the light source control box. The cavity is sealed with a main unit back cover 152.

[0031] The replaceable filter assembly includes,

[0032] The filter box cover 11 is provided with an upper connecting connector 12 for connecting to the cut protective sleeve 3;

[0033] The filter box lower cover 13 is provided with a lower connecting joint 14 for connection to a negative pressure device; and

[0034] The filter element 15 has a filter material in the middle and sealing rings 151 on both sides of the filter material that cooperate with the upper cover 11 and the lower cover 13 of the filter box.

[0035] The filter element 15 has a back cover 152 connected to the main unit, so that when the main unit is disassembled and the filter material is replaced, the filter element 15 can be replaced by reinstalling the main unit back cover 152.

[0036] The filter element 15 includes a storage channel 153. A fixed net 154 is fixed at one end of the storage channel 153, and a movable net 155 is detachable at the other end. The filter material is placed in the storage channel 153 and is limited by the fixed net 154 and the movable net 155. The sealing ring 151 is located at the edges of the openings at both ends of the storage channel 153.

[0037] The replaceable filter assembly is installed between the upper and lower covers of the filter box via a plug-in connection. The replaceable filter assembly is equipped with a sealing ring to seal the channel, preventing gas leakage and ensuring effective smoke extraction during surgery. The main unit's rear cover 152 is integrated with the filter element 15. The rear cover 152 is secured to the light source control box using a snap-fit ​​mechanism or other easily removable method, allowing users to replace the entire filter assembly in one step by removing the rear cover.

[0038] It should be noted that the lower connecting joint 14 can be equipped with a valve 141 to control the on / off state of the negative pressure.

[0039] The aforementioned filter materials include at least one or two of activated carbon filter cotton 156 and filter cotton 157.

[0040] The invention also includes a power supply mechanism, the power supply mechanism comprising:

[0041] Lithium battery 21 enables charging and power supply;

[0042] The second substrate 23 is connected to the lithium battery 21 and is powered by the lithium battery 21; and

[0043] The first substrate 22 is provided with a charging port 24 and a charging protection circuit, and is connected to the second substrate 23 and the lithium battery 21 to charge the lithium battery 21.

[0044] It also includes a third substrate 25, and the third substrate 25 and the second substrate 23 are detachably connected to the connecting terminals provided on the cut-out protective sleeve 3, for supplying power to the light source inside the cut-out protective sleeve 3.

[0045] The lithium battery powers the second substrate, which is interconnected with the third and first substrates via terminal wires. The first substrate is equipped with a charging port and a charging protection circuit, allowing an external charging device to safely and reliably charge the lithium battery to meet the needs of repeated use of the light source control box.

[0046] The third substrate 25 is adjacent to the upper connecting connector 12.

[0047] like Figure 8-10As shown: The lower retaining ring of the cut protective sleeve of the present invention is provided with at least a light source and a negative pressure port, and the light source is connected to the light source control box through the wire 33 to realize power supply, and the negative pressure port is connected to the light source control box through the negative pressure channel 32 to realize negative pressure attraction;

[0048] The lower retaining ring is connected to a multi-cavity connecting tube 31. At least one channel in the multi-cavity connecting tube 31 is used to place the wire 33, and at least one channel is used as a negative pressure channel 42.

[0049] Furthermore, a connector 35 is fixedly provided at the end of the multi-cavity connecting tube 31, allowing the multi-cavity connecting tube 31 to be detached and connected to the light source control box.

[0050] Generally, the lower retaining ring of current cut-out protective sleeves is mainly equipped with a light source (LED light source) and a negative pressure suction function (with a negative pressure port), so currently, a dual-chamber connecting tube is sufficient to meet the main functions. In order to ensure that the connector 35 of the multi-chamber connecting tube 31 can be connected to the light source control box, the light source control box also needs to be equipped with a corresponding connecting slot at the connection point.

[0051] The end of the wire 33 is provided with a connection terminal 34, which is electrically connected to the substrate provided in the light source control box.

[0052] The negative pressure channel 32 is provided with a connecting pipe joint 36 at its end, and the connecting pipe joint 36 is provided with an upper connecting joint for interference fit with the light source control box.

[0053] The connecting terminal 34 and connecting pipe connector 36 here are connected to the corresponding interfaces on the light source control box. This ensures that after the connector 35 and the light source control box are connected, the connecting terminal 34 and the connecting pipe connector 36 are also connected, respectively realizing power supply and negative pressure attraction.

[0054] like Figure 3 , 4 As shown: In actual use, the cut-off protective sleeve 3 is equipped with a light source (LED light source) and a negative pressure suction function (with a negative pressure port), achieving smoke exhaust through negative pressure. The light source function contains a wire, which is connected to the third substrate via a connecting terminal, and the light source system is powered by a lithium battery. The third substrate 25 and the upper connecting connector 12 are adjacent, so that the negative pressure channel 32 and the wire 33 can be placed together in a multi-cavity connecting pipe 31 (double-cavity connecting pipe), and the connecting terminal is detachable from the third substrate, and the upper connecting connector and the negative pressure channel are detachable from each other. This allows for a quick and easy connection of the power supply and negative pressure source to the cut-off protective sleeve 3.
