Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a constant temperature front-end heat dissipation structure. Background Technology

[0002] Currently, most disposable endoscopes on the market use an LED+CMOS combination to address the illumination issue. LEDs are significantly cheaper than the traditional fiber optic solution for endoscopes. However, LEDs generate heat during illumination, and overheating can pose a risk of localized burns to human tissue. Therefore, power reduction measures are usually implemented to keep LEDs at a lower operating temperature. However, this significantly reduces the brightness of LEDs compared to fiber optics, affecting the endoscope's illumination. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to solve the problem that the existing technology usually takes measures to reduce the power of LEDs to keep them at a lower operating temperature, but this will greatly reduce the brightness of LEDs compared with optical fibers, affecting the illumination of the endoscope. A constant temperature front-end heat dissipation structure is provided.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a constant-temperature tip heat dissipation structure, comprising:

[0005] Light-emitting elements are used to provide a light source;

[0006] The terminal block is provided with a first mounting hole for mounting the light-emitting element and a heat dissipation channel surrounding the first mounting hole;

[0007] The constant temperature heat dissipation mechanism includes a heat dissipation pipe installed in the heat dissipation channel. The heat dissipation pipe extends out of the end seat and is connected to a temperature measuring module for measuring the temperature inside the heat dissipation pipe, a flow rate control module for controlling the flow rate of the heat dissipation fluid inside the heat dissipation pipe, and a fluid drive module for driving the flow of the heat dissipation fluid.

[0008] Furthermore, the heat dissipation pipeline includes multiple annular pipes distributed axially along the tip seat and a connecting pipe for connecting the multiple annular pipes.

[0009] Furthermore, the heat dissipation fluid in the heat dissipation pipe is coolant or cold air.

[0010] Furthermore, the tip seat is made of a transparent material, or one end of the tip seat along its axial direction is a tip surface from which the light source emitted by the light-emitting element is emitted, and the tip surface is made of a transparent material.

[0011] Furthermore, the tip seat is also provided with an instrument channel for surgical instruments to pass through. The instrument channel is arranged side by side with the first mounting hole, and a heat dissipation channel surrounds the outside of the instrument channel and the first mounting hole.

[0012] Furthermore, it also includes an image acquisition element, wherein there are two light-emitting elements and the two light-emitting elements are located on both sides of the image acquisition element.

[0013] Furthermore, the tip surface includes a first end surface facing the image acquisition element and the light-emitting element and a second end surface facing the instrument channel. The first end surface and the second end surface are connected by an arc transition, and the second end surface gradually tilts towards the operator along the direction away from the first end surface.

[0014] Furthermore, the connecting pipe extends out of the terminal seat to form a fluid inflow section and a fluid outflow section, and the surface of the fluid outflow section is coated with a temperature-sensing coating.

[0015] The beneficial effects of this utility model are as follows: This utility model uses a heat dissipation pipe surrounding the light-emitting element to uniformly dissipate heat at the tip, and uses a temperature control system consisting of a temperature-measuring coating, a temperature-measuring module, a flow rate control module, and a fluid drive module to monitor the temperature of the heat dissipation pipe in real time, so that the tip can maintain a temperature suitable for human body without reducing the power of the light-emitting element, thereby enabling the endoscope to obtain high illumination and improving surgical efficiency.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention. Therefore, they only show the components relevant to the present invention. Orientations and references (e.g., up, down, left, right, etc.) are only used to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0033] like Figure 3 and Figure 7 As shown, a constant-temperature front-end heat dissipation structure includes:

[0034] Light-emitting element 1 is used to provide a light source. In this embodiment, light-emitting element 1 is an LED.

[0035] The tip seat 2 is roughly cylindrical in shape, which can reduce tissue damage when inserted into the human body. The tip seat 2 is provided with a first mounting hole 201 for mounting the light-emitting element 1 and a heat dissipation channel surrounding the first mounting hole 201. The light-emitting element 1 is installed in the first mounting hole 201 with its light-emitting surface facing the tissue side, for illuminating the tissue.

[0036] The constant temperature heat dissipation mechanism includes a heat dissipation pipe 3 installed in the heat dissipation channel. The heat dissipation pipe 3 is pre-embedded in the heat dissipation channel and injection molded. The heat dissipation pipe 3 surrounding the light-emitting element 1 can dissipate heat evenly at the tip.

[0037] The heat dissipation pipe 3 extends out of the terminal block 2 and is connected to a temperature measuring module 4 for measuring the temperature inside the heat dissipation pipe 3, a flow rate control module 5 for controlling the flow rate of the heat dissipation fluid inside the heat dissipation pipe 3, and a fluid drive module 6 for driving the flow of the heat dissipation fluid. The temperature measuring module 4 can be, but is not limited to, an infrared thermometer. The flow rate control module 5 can be set to a temperature suitable for the human body, generally between 35° and 37°. The fluid drive module 6 can be, but is not limited to, a delivery pump. The delivery pump delivers the heat dissipation fluid to the heat dissipation pipe 3 and can control the flow rate of the heat dissipation fluid.

[0038] During surgery, the light-emitting element 1 is turned on, and the temperature measuring module 4 converts the measured temperature signal into an electrical signal, which is then transmitted to the flow rate control module 5. When the measured temperature is higher than the set temperature, the flow rate control module 5 sends a signal to the delivery pump, which increases the flow rate of the fluid entering the heat dissipation pipe 3, thereby accelerating the cooling process by removing the heat generated by the light-emitting element 1. Conversely, the flow rate is reduced to ensure that the tip is kept at a suitable temperature, achieving the purpose of constant temperature control.

[0039] In some examples, such as Figure 5 and Figure 6 As shown, the heat dissipation pipe 3 includes multiple ring pipes 301 distributed along the axial direction of the tip seat 2 and a connecting pipe 302 for connecting the multiple ring pipes 301. The connecting pipe 302 extends axially and has two sections. Both connecting pipes 302 extend out of the tip seat 2 towards the operator and form a fluid inlet and a fluid outlet. The fluid drive module 6 sends heat dissipation fluid at a predetermined flow rate into the fluid inlet of the heat dissipation pipe 3. The heat dissipation fluid enters the multiple ring pipes 301 sequentially from one of the connecting pipes 302 to dissipate heat from the tip, and then flows out from the fluid outlet of the other connecting pipe 302. After cooling, it enters the tip seat 2 again through the delivery pump to form a cycle. Alternatively, the heat dissipation pipe 3 can also be a spiral pipe, which extends along the axial direction of the tip seat 2.

[0040] In some examples, the heat dissipation fluid of the heat dissipation pipe 3 is coolant or cold air, that is, water cooling or air cooling can be used to dissipate heat from the tip seat 2 in this embodiment.

[0041] In some examples, the tip seat 2 is made of transparent material, and the light source emitted by the light-emitting element 1 illuminates the tissue directly through the tip seat 2. Alternatively, one end of the tip seat 2 along its axial direction is a tip surface 203 from which the light source emitted by the light-emitting element 1 is emitted. The tip surface 203 is made of transparent material, that is, the side surface of the tip seat 2 other than the tip surface 203 is made of opaque material. The tip surface 203 is sealed on the side surface of the tip seat 2, and the light-emitting element 1 illuminates the tissue through the tip surface 203.

[0042] In some examples, such as Figures 1-3 As shown, the tip seat 2 is also provided with an instrument channel 204 for surgical instruments to pass through. The instrument channel 204 is arranged side by side with the first mounting hole 201. The heat dissipation channel surrounds the outside of the instrument channel 204 and the first mounting hole 201 to avoid interference with the surgical instruments.

[0043] In some examples, such as Figure 1 and Figure 3As shown, it also includes an image acquisition element 7. There are two light-emitting elements 1, and the two light-emitting elements 1 are located on both sides of the image acquisition element 7. The two light-emitting elements 1 together provide a light source for the image acquisition element 7. The tip seat 2 has a second mounting hole 202 for mounting the image acquisition element 7. The two first mounting holes 201 are connected to the second mounting hole 202 located between them. The second mounting hole 202 passes through the tip surface 203 of the tip seat 2 along the axial direction. The end face of the image acquisition element 7 is flush with the tip surface 203.

[0044] In some examples, such as Figure 1 and Figure 4 As shown, the tip surface 203 includes a first end surface 2031 facing the image acquisition element 7 and the light-emitting element 1 and a second end surface 2032 facing the instrument channel 204. The first end surface 2031 and the second end surface 2032 are connected by an arc transition to reduce patient discomfort. The second end surface 2032 gradually tilts towards the operator along the direction away from the first end surface 2031 to form an inclined plane or inclined arc surface to form a guide structure to facilitate the tip entering the human body.

[0045] In some examples, the connecting pipe 302 extends out of the tip seat 2 to form a fluid inflow section 3021 and a fluid outflow section 3022, and the surface of the fluid outflow section 3022 is coated with a temperature-sensing coating, which can improve the accuracy of temperature measurement.

[0046] Working principle:

[0047] During the procedure, the light-emitting element 1 is turned on, and the temperature measuring module 4 converts the measured temperature signal into an electrical signal, which is then transmitted to the flow rate control module 5. When the measured temperature is higher than the set temperature, the flow rate control module 5 sends a signal to the delivery pump, which increases the flow rate at the fluid inlet. The accelerated cooling fluid enters multiple ring pipes 301 sequentially from one of the connecting pipes 302 to dissipate heat from the tip, and then flows out from the fluid outlet of another connecting pipe 302, thereby accelerating cooling. Conversely, the flow rate is reduced to ensure that the tip is kept at a suitable temperature, achieving the purpose of constant temperature control.

[0048] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
