Description

Technical Field

[0001] This invention relates to the field of medical surgical equipment technology, and in particular to a beam converter and an endoscope system. Background Technology

[0002] Current endoscopic light guiding devices generally consist of a beam guide, an adapter, and a retaining ring. The beam guide is housed within the adapter and secured by the retaining ring. However, existing beam guide retaining rings often have a gap between them after connection to the adapter, or, to ensure proper fixation, the beam guide and retaining ring need to be integrated using heat pressing or adhesive. However, the optical fiber in the beam guide is made of glass, which has a low thermal conductivity. Air gaps or adhesive between the retaining ring and the beam guide can significantly impede the smooth conduction of heat through the adapter and retaining ring to the outside, leading to overheating of the entire light guiding device, operational difficulties, and even fiber optic glass melting and damage to the device. Summary of the Invention

[0003] The purpose of this invention is to provide a beam converter that can solve the problem of heat dissipation in the beam guide and improve the heat dissipation effect of the beam guide.

[0004] The above-mentioned objectives of the present invention can be achieved by the following technical solutions:

[0005] This invention provides a beam switching device, comprising:

[0006] The connecting mechanism has a receiving hole for accommodating the beam guide, and a heat dissipation part is provided at the front end of the connecting mechanism, with the outer peripheral surface of the beam guide attached to the heat dissipation part.

[0007] The beam switching device provided by the present invention forms a heat dissipation part at the front end of the connecting mechanism that is in close contact with the outer peripheral surface of the beam guide, so that the heat generated during the operation of the beam guide is quickly transferred to the outside through the heat dissipation part, thereby effectively reducing the overall operating temperature of the beam guide and the beam switching device, reducing the impact of overheating of the beam guide equipment on the operation of the operator, and reducing the self-melting damage of the fiber glass of the beam guide due to overheating.

[0008] In a preferred embodiment, the diameter of the receiving hole is radially tapering from the rear end to the front end to form the heat dissipation portion at the front end of the connecting mechanism.

[0009] By setting the receiving hole at the front end of the connecting mechanism to a radially tapering shape from the rear end to the front end, the structure of the heat dissipation part can be matched with that of the beam guide, thereby making the heat dissipation part and the beam guide fit tightly together and achieving good heat dissipation.

[0010] In a preferred embodiment, the connecting mechanism includes:

[0011] The connecting pipe has a first receiving hole formed inside;

[0012] An installation tube is provided at the front end of the connecting tube, and a second receiving hole is formed inside it. The first receiving hole and the second receiving hole are combined to form the receiving hole.

[0013] A socket fitting is fitted onto the mounting tube and connected to the front end of the connecting tube;

[0014] In the case where the socket is fitted onto the mounting tube and connected to the connecting tube, the mounting tube forms the heat dissipation section.

[0015] During the installation of the beam guide, the beam guide is first inserted into the first receiving hole formed by the connecting tube, with the front end of the beam guide extending from the front end of the first receiving hole. At this time, the separately provided mounting tube can be sleeved onto the beam guide. Then, by fitting the fitting onto the mounting tube, the beam guide is completely installed and fixed. The entire installation process is quick and convenient. After installation, the front end of the mounting tube forms a heat dissipation section, which fits against the outer circumference of the beam guide, achieving good heat dissipation. Setting the mounting tube separately also facilitates checking the condition of its heat dissipation section and makes it easy to replace with a new mounting tube, ensuring the stability of the heat dissipation section.

[0016] In a preferred embodiment, the mounting tube has a positioning portion and a plurality of elastic mounting portions. The elastic mounting portions extend from the positioning portion toward the front end and are evenly distributed along the circumference of the positioning portion. Adjacent elastic mounting portions are provided with notches or grooves.

[0017] By providing multiple flexible mounting parts at the front end of the mounting tube, the inner diameter of the second receiving hole can be varied according to the diameter of the guide beam, or the inner diameter of the second receiving hole can be slightly larger than the diameter of the guide beam, thus allowing the mounting tube to be easily fitted onto the guide beam.

[0018] In a preferred embodiment, the inner diameter of the socket is radially tapered from the rear end to the front end to form an inner conical surface at the front end of the socket, and the front ends of the plurality of elastic mounting portions are radially tapered from the rear end to the front end to form an outer conical surface at the front end of the mounting tube.

[0019] When the fitting is sleeved on the mounting tube and connected to the connecting tube, the inner conical surface can abut against the outer conical surface.

[0020] During the process of fitting the mounting tube onto the front end of the beam guide and then fitting the connector onto the mounting tube, the inner conical surface of the connector naturally presses against the outer conical surface of the front end of the mounting tube, causing multiple elastic mounting parts to compress radially inward and fit tightly against the beam guide. As a result, the beam guide is contracted and fixed by the multiple elastic mounting parts, ensuring that the heat dissipation area formed by these parts is in close contact with the beam guide, achieving excellent heat dissipation. Furthermore, when disassembling the beam guide, the multiple elastic mounting parts return to their original positions after the connector is removed, facilitating the removal of the beam guide from the connecting mechanism.

[0021] In a preferred embodiment, a positioning stepped hole and a connecting stepped hole are formed on the inner wall surface of the front end of the connecting pipe. The connecting stepped hole is located at the front end of the positioning stepped hole. The positioning stepped hole, the connecting stepped hole, and the first receiving hole are coaxially arranged. The diameter of the positioning stepped hole is larger than the diameter of the first receiving hole, and the diameter of the connecting stepped hole is larger than the diameter of the positioning stepped hole. The positioning part is correspondingly disposed in the positioning stepped hole, and the sleeve is connected to the connecting stepped hole.

[0022] By forming a positioning stepped hole on the connecting tube, the mounting tube can be quickly positioned to the correct installation position when it is installed on the beam guide. Correspondingly, the connecting stepped hole also allows the socket to be quickly positioned and connected when it is fitted onto the mounting tube.

[0023] After the mounting tube is fitted onto the front end of the beam guide, the positioning part of the mounting tube is correspondingly set in the positioning stepped hole. The rear end of the positioning part abuts against the protrusion of the positioning stepped hole. After the socket is fitted onto the mounting tube and connected to the connecting tube, the rear end face of the socket abuts against the front end face of the positioning part, so that the mounting tube is positioned and fixed.

[0024] In a preferred embodiment, the inner circumferential surface of the front end of the socket extends radially to form a shielding portion, and the front end surface of the light guide abuts against the shielding portion.

[0025] By setting a shielding part on the socket, the beam guide can be further stabilized and positioned, and the heat generated by the light illuminating the edge of the beam guide can be quickly dissipated through the shielding part, thereby fully ensuring the heat dissipation effect of the beam guide.

[0026] In a preferred embodiment, the diameter of the outer peripheral surface of the front end of the socket is radially tapered from the rear end to the front end.

[0027] By setting a conical surface at the front end of the socket, the light guide device can be more easily detached and connected by plugging and unplugging, thus improving the ease of operation.

[0028] In a preferred embodiment, the connecting mechanism includes:

[0029] Connecting pipe;

[0030] Multiple flexible mounting portions are provided, which extend from the connecting pipe toward the front end and are evenly distributed along the circumference of the connecting pipe. Adjacent flexible mounting portions are provided with notches or grooves.

[0031] By directly molding multiple flexible mounting parts onto the connecting tube in one piece, the operation during beam guide installation can be reduced, allowing the beam guide to be directly embedded between multiple flexible mounting parts, while simultaneously serving the function of heat conduction and dissipation.

[0032] In a preferred embodiment, the plurality of elastic mounting portions are arranged to bend radially inward from the rear end to the front end, and the plurality of elastic mounting portions together form the heat dissipation portion.

[0033] The structure of the heat dissipation unit is matched with that of the beam guide, so that the heat dissipation unit and the beam guide are in close contact, thereby achieving a good heat dissipation effect.

[0034] Another object of the present invention is to provide an endoscope system that can solve the problem of heat dissipation of the beam guide and improve the heat dissipation effect of the beam guide, comprising:

[0035] As described above, the beam adapter has an interface groove and a positioning boss on its connecting tube. The interface groove extends circumferentially along the connecting tube and is located in the middle of the connecting tube. The positioning boss extends circumferentially along the connecting tube and is located at the rear end of the interface groove.

[0036] Endoscope;

[0037] An endoscope light source, wherein the beam adapter extends into the endoscope light source and is detachably connected to the endoscope light source via the positioning boss and the interface groove;

[0038] A beam guide is connected at one end to the endoscope light source via the beam adapter and at the other end to the endoscope, so that the light emitted by the endoscope light source is transmitted to the endoscope via the beam guide.

[0039] An endoscope host, wherein the image information acquired by the endoscope can be transmitted to the endoscope host.

[0040] The endoscope system provided by this invention features a heat dissipation section formed at the front end of the connecting mechanism of the beam converter, which closely fits the outer peripheral surface of the beam guide. This allows the heat generated during the beam guide's operation to be quickly transferred to the outside through the heat dissipation section, effectively reducing the overall operating temperature of the beam guide and the beam converter. This reduces the impact of overheating on operator function and minimizes the risk of self-melting damage to the fiber optic glass of the beam guide due to overheating. Furthermore, by providing interface grooves and positioning bosses on the connecting tube, the connecting mechanism can be quickly installed or disassembled via plug-and-play, further improving the ease of use of the beam converter of this invention.

[0053] The following is a brief description of the structure of existing beam adapters. Please refer to [link / reference needed]. Figure 1 and Figure 2 As shown, existing beam adapters mainly include an integrated beam adapter fixing cylinder 102. Multiple optical fibers 101 are first bundled and fixed inside a beam fixing ring 103, and then passed through the beam adapter fixing cylinder 102. However, there is a gap between the end of the beam fixing ring 103 and the inner wall of the beam adapter fixing cylinder 102. This causes the heat of the optical fibers 101 to not be conducted away from the beam adapter fixing cylinder 102 in time, resulting in the optical fibers 101 becoming too hot. This not only poses a risk of the optical fiber glass melting due to high temperature, but also affects the operator's contact and control of the beam adapter.

[0054] The beam adapter provided in this application embodiment can effectively improve the heat dissipation effect on optical fibers. Please refer to... Figure 3 As shown, an embodiment of the present invention provides a beam switching device, including: a connecting mechanism 1, the connecting mechanism 1 having a receiving hole 11 for accommodating a beam guide 2, a heat dissipation part being provided at the front end of the connecting mechanism 1, and the outer peripheral surface of the beam guide 2 being attached to the heat dissipation part.

[0055] The beam switching device of this invention has a heat dissipation part formed at the front end of the connecting mechanism 1, which is in close contact with the outer peripheral surface of the beam guide 2. This allows the heat generated during the operation of the beam guide 2 to be quickly transferred to the outside through the heat dissipation part, thereby effectively reducing the overall operating temperature of the beam guide 2 and the beam switching device. This reduces the impact of overheating on the beam guide equipment and the operator's operation, while also reducing the risk of self-melting damage to the fiber glass of the beam guide 2 due to overheating. Specifically, the connecting mechanism 1 can be inserted into the light source device. The direction of movement of the connecting mechanism 1 when inserted into the light source device is defined as the front side, that is, the front end of the connecting mechanism 1 enters the light source device first.

[0056] In the experimental verification, the ambient temperature was set to 25℃, the light source power of the beam guide was 80W, and the entrance diameter of the beam guide was 4.8mm. The experimental method was as follows: the beam guide was connected to an existing beam adapter, a thermocouple was connected to the end side of the existing beam adapter, and the beam guide was kept running under the above-mentioned conditions until the temperature of the end side of the existing beam adapter stabilized. Then, the beam guide was pulled out, and the temperature of the glass at the end of the beam guide was immediately measured. The beam guide was then connected to the beam adapter device provided in this embodiment, a thermocouple was connected to the end side of the beam adapter, and the beam guide was kept running under the above-mentioned conditions until the temperature of the end side of the beam adapter stabilized. Then, the beam guide was pulled out, and the temperature of the glass at the end of the beam guide was immediately measured. After multiple experiments, the following results were obtained: the end side temperature of the existing beam adapter was 70℃, and the end glass temperature of the beam guide was 100℃; while the end side temperature of the beam adapter device in this embodiment was 46.9℃, and the end glass temperature of the beam guide was 40.4℃. It is evident that the beam adapter in this embodiment has a good heat dissipation effect on the beam guide.

[0057] Specifically, the structure of the heat dissipation part is related to the structure of the beam guide 2. In one feasible embodiment, the diameter of the front end of the beam guide 2 is radially tapered from the rear end to the front end, forming a conical surface for focusing light. Correspondingly, in a preferred embodiment, the diameter of the receiving hole 11 is radially tapered from the rear end to the front end, so as to form a heat dissipation part at the front end of the connecting mechanism 1. By setting the receiving hole 11 at the front end of the connecting mechanism 1 in a radially tapering form from the rear end to the front end, the heat dissipation part can be matched with the structure of the beam guide 2, thereby making the heat dissipation part fit tightly with the beam guide 2 and achieving good heat dissipation. In another feasible embodiment, the diameter of the front end of the beam guide 2 does not change, so as to keep the light irradiation range. Correspondingly, the diameter of the receiving hole 11 also remains unchanged, so as to fit against the outside of the beam guide 2.

[0058] Please refer to the following for details. Figure 4 , Figure 5 and Figure 6As shown, in a preferred embodiment, the connecting mechanism 1 includes: a connecting pipe 12 with a first receiving hole 121 formed inside; a mounting pipe 13 disposed at the front end of the connecting pipe 12 with a second receiving hole 131 formed inside, the first receiving hole 121 and the second receiving hole 131 combined to form a receiving hole 11; and a sleeve 14 sleeved on the mounting pipe 13 and connected to the front end of the connecting pipe 12; wherein, when the sleeve 14 is sleeved on the mounting pipe 13 and connected to the connecting pipe 12, the mounting pipe 13 forms a heat dissipation part.

[0059] During the installation of the beam guide 2, it can be first inserted into the first receiving hole 121 formed by the connecting tube 12, with the front end of the beam guide 2 extending out from the front end of the first receiving hole 121. At this time, the separately provided mounting tube 13 can be sleeved on the beam guide 2. Then, by sleeved on the mounting tube 13, the beam guide 2 is completely installed and fixed. The entire installation process is quick and convenient. After installation, the mounting tube 13 forms a heat dissipation part, which fits against the outer peripheral surface of the beam guide 2 to achieve good heat dissipation. Setting the mounting tube 13 separately also makes it easy to check the condition of its heat dissipation part and to replace it with a new one, so as to ensure the stability of the heat dissipation part.

[0060] Specifically, to improve the convenience of mounting the mounting tube 13 onto the beam guide 2, in a preferred embodiment, the mounting tube 13 has a positioning portion 132 and a plurality of elastic mounting portions 133. The elastic mounting portions 133 extend from the positioning portion 132 towards the front end, and the plurality of elastic mounting portions 133 are evenly distributed along the circumference of the positioning portion 132. A notch 134 is formed between adjacent elastic mounting portions 133. By providing a plurality of elastic mounting portions 133 at the front end of the mounting tube 13, the inner diameter of the second receiving hole 131 can vary according to the diameter of the beam guide 2, or the inner diameter of the second receiving hole 131 can be slightly larger than the diameter of the beam guide 2, thereby allowing the mounting tube 13 to be conveniently mounted onto the beam guide 2.

[0061] Furthermore, the structural design of the mounting tube 13 effectively improves the heat dissipation effect of the heat dissipation section. In a preferred embodiment, the inner diameter of the front end of the sleeve 14 is radially tapered from the rear end to the front end, forming an inner conical surface 141 at the front end of the sleeve 14. The front ends of the plurality of elastic mounting portions 133 are radially tapered from the rear end to the front end, forming an outer conical surface at the front end of the mounting tube 13. When the sleeve 14 is fitted onto the mounting tube 13 and connected to the connecting tube 12, the inner conical surface 141 can abut against the outer conical surface, and the sleeve 14 squeezes the plurality of elastic mounting portions 133 radially inward, so that the plurality of elastic mounting portions 133 together form a heat dissipation section.

[0062] During the process of mounting the mounting tube 13 onto the front end of the beam guide 2 and fitting the connector 14 onto the mounting tube 13, the inner conical surface 141 of the connector 14 naturally presses against the outer conical surface of the front end of the mounting tube 13, causing the multiple elastic mounting parts 133 to compress radially inward and fit tightly against the beam guide 2. Thus, the beam guide 2 is contracted and fixed by the multiple elastic mounting parts 133, allowing the heat dissipation portion formed by the multiple elastic mounting parts 133 to fit against the beam guide 2, achieving a good heat dissipation effect. Simultaneously, when disassembling the beam guide 2, the multiple elastic mounting parts 133 can return to their original position after the connector 14 is removed, facilitating the removal of the beam guide 2 from the connecting mechanism 1. Specifically, the angles of the inner conical surface 141 of the socket 14 and the outer conical surface of the mounting tube 13 can be determined according to the shape of the front end of the beam guide 2. For example, when a beam guide 2 without a conical surface at the front end is used, the angles of the inner conical surface 141 of the socket 14 and the outer conical surface of the mounting tube 13 can be smaller, or the conical surface can be omitted to reduce the pressure generated on the beam guide 2. To ensure good elasticity of the elastic mounting part 133 and to ensure the thermal conductivity of the heat dissipation part, the mounting tube 13 is generally made of thermally conductive plastic.

[0063] To further improve the ease of installation between the connecting mechanism 1 and the beam guide 2, in a preferred embodiment, a positioning stepped hole 122 and a connecting stepped hole 123 are formed on the inner wall surface of the front end of the connecting tube 12. The connecting stepped hole 123 is located at the front end of the positioning stepped hole 122. The positioning stepped hole 122, the connecting stepped hole 123, and the first receiving hole 121 are coaxially arranged. The diameter of the positioning stepped hole 122 is larger than the diameter of the first receiving hole 121, and the diameter of the connecting stepped hole 123 is larger than the diameter of the positioning stepped hole 122. By forming the positioning stepped hole 122 on the connecting tube 12, the mounting tube 13 can be quickly positioned to the correct installation position when installed on the beam guide 2. Correspondingly, the connecting stepped hole 123 allows the sleeve 14 to be quickly positioned and connected when fitted onto the mounting tube 13.

[0064] Please refer to the following: Figure 7As shown, the installation and positioning of the mounting tube 13 and the socket 14 are described as follows: In a preferred embodiment, the positioning part 132 of the mounting tube 13 is correspondingly disposed in the positioning stepped hole 122, and the socket 14 is connected to the connecting stepped hole 123. The positioning part 132 is simultaneously restricted by the rear end face of the socket 14 and the positioning stepped hole 122, so that the mounting tube 13 is fixedly disposed on the connecting tube 12. After the mounting tube 13 is sleeved on the front end of the beam guide 2, the positioning part 132 of the mounting tube 13 is correspondingly disposed in the positioning stepped hole 122, and the rear end of the positioning part 132 abuts against the protrusion of the positioning stepped hole 122. After the socket 14 is sleeved on the mounting tube 13 and connected to the connecting tube 12, the rear end face of the socket 14 abuts against the front end face of the positioning part 132, so that the mounting tube 13 is positioned and fixed. Specifically, the socket 14 and the connecting pipe 12 can be detachably connected by a threaded connection or by a snap-fit ​​connection. Alternatively, the socket 14 and the connecting pipe 12 can be fixedly connected by adhesive bonding or welding. The specific connection method is not limited.

[0065] Please refer to the following: Figure 6 As shown, to further ensure the heat dissipation effect of the beam guide 2, in a preferred embodiment, a shielding portion 142 is formed by radially extending the front end of the socket 14, and the edge of the front end face of the beam guide 2 can abut against the shielding portion 142. By providing the shielding portion 142 on the socket 14, the beam guide 2 is further stabilized and positioned, and the heat generated by the light irradiating the edge of the beam guide 2 can be quickly dissipated through the shielding portion 142, thereby fully ensuring the heat dissipation effect of the beam guide 2.

[0066] To facilitate the installation and removal of the light guide device on medical equipment, in a preferred embodiment, the diameter of the outer circumferential surface of the front end of the socket 14 is radially tapered from the rear end to the front end. By providing a tapered surface at the front end of the socket 14, the light guide device can be more easily detached and connected by plugging and unplugging, improving operational convenience.

[0067] The following embodiments illustrate the structure and connection relationship of the heat dissipation part when it is integrally formed by the connecting mechanism 1.

[0068] Please see Figure 8 As shown, in a preferred embodiment, the connecting mechanism 1 includes: a connecting tube 12a; and a plurality of elastic mounting portions 133a, which extend from the connecting tube 12a toward the front end and are evenly distributed along the circumference of the connecting tube 12a. A notch 134a is formed between adjacent elastic mounting portions 133a. By directly and integrally molding the plurality of elastic mounting portions 133a onto the connecting tube 12a, the operation during the installation of the beam guide 2 can be reduced, allowing the beam guide 2 to be directly embedded between the plurality of elastic mounting portions 133a, while simultaneously serving the function of heat conduction and dissipation.

[0069] To further improve the stability of the beam guide 2 installation and enhance heat dissipation performance, in a preferred embodiment, multiple elastic mounting portions 133a are arranged to bend radially inward from the rear end to the front end, and the multiple elastic mounting portions 133a together form a heat dissipation portion. Specifically, the degree of bending of the elastic mounting portions 133a can be determined according to the structure of the beam guide 2. For example, when a beam guide 2 without a tapered front end is used, the degree of bending of the elastic mounting portions 133a can be smaller to reduce the pressure generated on the beam guide 2. Specifically, an outer tapered surface, as described above for the mounting tube 13, can also be formed on the multiple elastic mounting portions 133a. Correspondingly, a sleeve 14 with an inner tapered surface 141 can also be fitted over the multiple elastic mounting portions 133a to produce a bending effect by elastically compressing the elastic mounting portions 133a through the sleeve 14.

[0070] After the installation of the beam guide 2 and the connecting mechanism 1 is completed, the connecting mechanism 1 should be placed on the light source so that the light from the light source can be transmitted to the target position through the beam guide 2.

[0071] This invention also provides an endoscope system, which can be referred to in conjunction with the invention. Figure 4 , Figure 9 and Figure 10 As shown, the endoscope system includes: a beam converter as described above, wherein the connecting tube 12 of the beam converter has an interface groove 124 and a positioning boss 125, the interface groove 124 extends circumferentially along the connecting tube 12 and is located in the middle of the connecting tube 12, and the positioning boss 125 extends circumferentially along the connecting tube 12 and is located at the rear end of the interface groove 124; an endoscope 3; an endoscope light source 4, wherein the connecting mechanism 1 of the beam converter extends into the endoscope light source 4 and is detachably connected to the endoscope light source through the positioning boss 125 and the interface groove 124; a beam guide 2, one end of which is connected to the endoscope light source 4 through the connecting mechanism 1 of the beam converter, and the other end is connected to the endoscope 3, so that the light emitted by the endoscope light source 4 is transmitted to the endoscope 3 through the beam guide 2; an endoscope host 5; and an endoscope data cable 6, both ends of which are connected to the endoscope 3 and the endoscope host 5 respectively, so as to transmit the image information acquired by the endoscope 3 to the endoscope host 5.

[0072] The endoscope system provided by this invention features a heat dissipation section formed at the front end of the connecting mechanism 1 of the beam converter, which closely fits the outer peripheral surface of the beam guide 2. This allows the heat generated during the operation of the beam guide 2 to be quickly transferred to the outside through the heat dissipation section, effectively reducing the overall operating temperature of the beam guide 2 and the beam converter. This reduces the impact of overheating on operator work and also reduces the risk of self-melting damage to the fiber optic glass of the beam guide 2 due to overheating. Furthermore, by providing an interface groove 124 and a positioning boss 125 on the connecting tube 12, the connecting mechanism 1 can be quickly installed or disassembled via plug-and-play, further improving the ease of use of the beam converter.
