Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a novel laparoscope. Background Art

[0002] As a minimally invasive surgical method, laparoscopic technology can clearly observe the condition of the patient's abdominal tissues and organs through the laparoscope's micro-camera, quickly diagnose the disease and perform surgical treatment. Laparoscopic surgery does not require a large incision, which is more advantageous than traditional open surgery. It can also minimize the patient's hospital stay, reduce postoperative pain, speed up postoperative recovery and reduce the occurrence of complications.

[0003] The existing laparoscope cavity has low heat dissipation efficiency. After the laparoscope is used for a long time during surgery, the local temperature of the optical fiber is prone to rise, which makes the fibers inside the optical fiber easily damaged, causing optical fiber aging, and then leading to reduction or loss of optical signals. It is usually manifested as the optical signal becoming weak and unable to be effectively transmitted, shortening the service life of the laparoscope.

[0004] For example, Chinese Patent 202222546159.6 discloses a laparoscope, including a laparoscope body, characterized in that: a circular fixing ring is fixedly connected to the outer surface of the laparoscope body, and a shell is slidably fitted on the outer surface of the circular fixing ring; a conical silicone sleeve is provided at one end of the shell corresponding to the front of the laparoscope body, and the inner surface of the silicone sleeve is fitted with the outer surface of the laparoscope body; a No. 1 limiting groove communicating with the interior of the shell is provided on the surface of the shell; a No. 1 limiting plate fitted and matched with the inner wall of the No. 1 limiting groove is fixedly connected to the surface of the circular fixing ring; a curved connecting plate fitted with the outer surface of the shell is fixedly connected to one side of the curved connecting plate; and a spring is fixedly connected to the other end of the spring, and a fixing plate is fixedly connected. Although this patent improves the clarity of the front end surface of the laparoscope body, the heat dissipation effect inside the laparoscope body is poor, and the heat dissipation problem inside the laparoscope is not solved. Utility Model Content

[0005] Based on this, it is necessary to provide a new type of laparoscope to address the above technical problems, set a heat dissipation pipe in the laparoscope, and set a heat dissipation frame in the handheld part to improve the heat dissipation efficiency inside the laparoscope.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] Furthermore, the front tube includes a front tube body and a port, the signal connection channel is connected to an image acquisition device at the port, and the light guide channel forms a lighting device at the port.

[0009] Furthermore, the image acquisition device is a camera module; a first optical fiber channel is provided in the front tube, and the lighting device is the first optical fiber channel forming an optical fiber end at the port.

[0010] Furthermore, the light guiding channel includes a first optical fiber channel, a second optical fiber channel and a third optical fiber channel, and the second optical fiber channel and the third optical fiber channel are combined into the first optical fiber channel in the front tube.

[0011] Furthermore, the bottom surface of the heat sink is rectangular or square, and two bottom edges of the bottom surface of the heat sink adjacent to the handheld portion extend upward to form a protrusion, and the second optical fiber channel and the third optical fiber channel pass through the bottom surface of the heat sink.

[0012] Furthermore, the raised portion is a double-wing bent structure.

[0013] Furthermore, the heat dissipation pipe is placed below the first optical fiber channel, the second optical fiber channel and the third optical fiber channel.

[0014] Furthermore, a circuit board is provided in the handheld part, and an image processor is also provided on the circuit board; the signal connection channel includes a front-end signal line, a circuit board, a data line connector and a back-end signal line in sequence.

[0015] Furthermore, the heat dissipation pipe and the heat dissipation frame are made of any one of copper, aluminum and stainless steel.

[0016] Furthermore, the raised portion is an inclined surface, and strip-shaped raised portions are arranged at even intervals on the inner side of the inclined surface.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The new laparoscope provided by the utility model increases the heat dissipation area of ​​the light guide channel by arranging a heat dissipation pipe in the front tube inserted into the human body when in use, and the heat dissipation pipe is arranged below the first optical fiber channel, the second optical fiber channel and the third optical fiber channel to increase the heat dissipation efficiency in the front tube cavity while ensuring a smaller volume of the front tube; at the same time, a heat dissipation frame is arranged on the handheld part, and since the heat dissipation frame is provided with a raised part, its heat dissipation surface area is greatly increased, which can assist the heat dissipation of the second optical fiber channel and the third optical fiber channel in the handheld part on the one hand, and on the other hand, it can assist the circuit board to dissipate the heat caused by photoelectric conversion.

Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0028] As described in the background art, the heat dissipation speed inside the existing laparoscope is too slow, the internal optical fiber is prone to aging, and the service life of the laparoscope is too short.

[0029] In order to solve this technical problem, the utility model provides a novel laparoscope, which is provided with a heat dissipation structure inside.

[0030] Specifically, please refer to Figure 1-4 , the novel laparoscope specifically comprises:

[0031] The laparoscope body has a signal connection channel and a light guide channel running through it; the laparoscope body includes a front tube 1, a handheld part 2, a rear tube 3 and a three-way tube 4 in the horizontal direction; a heat dissipation pipe 140 is provided in the front tube 1, and the heat dissipation pipe 140 runs through the entire front tube 1 and is placed under the light guide channel; a heat dissipation frame 230 is provided in the handheld part 2, and the light guide channel passes through the heat dissipation frame 230.

[0032] In the new laparoscope provided by the utility model, a heat dissipation pipe 140 is arranged in the front tube 1, and the heat dissipation frame 140 is arranged under the light guide channel, which greatly increases the heat dissipation area and thus improves the heat dissipation speed of the light guide channel, preventing the excessively high temperature in the front tube 1 from affecting the conduction of the optical signal. In addition, a heat dissipation frame 230 is installed at the handheld part. Since the heat dissipation frame 230 has a raised portion, the heat dissipation surface area is effectively expanded. The heat dissipation frame 230 is fixed on the circuit board 250, and the light guide channel passes above it, thereby improving the heat dissipation effect of the heat dissipation frame 230 on the circuit board 250 and the light guide channel.

[0036] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0037] Example 1

[0038] Please refer to Figure 1-4 The present embodiment provides a novel laparoscope, which includes a laparoscope body, a signal connection channel and a light guide channel running through the laparoscope body, a data line connector 5 led out from the signal connection channel, an optical fiber connector 6 led out from the light guide channel, the optical fiber connector 6 is connected to an external light source to provide the laparoscope body with the light source required for image acquisition, and the data line connector 5 is connected to an external imaging device to convert the signal collected by the laparoscope body into a visible image.

[0039] Furthermore, the laparoscope body includes a front tube 1, a handheld part 2, a rear tube 3 and a three-way tube 4 in the horizontal direction. The signal connection channel and the light guide channel lead out a data line connector 5 and an optical fiber connector 6 from the three-way tube 4 respectively. The front tube 1 includes a front tube body and a port 110. The port 110 is provided with an image acquisition device. When in use, the doctor holds the handheld part 2 and inserts the port 110 into the patient's body to collect the internal structure status to provide support for inspection or surgery.

[0040] Furthermore, the image acquisition device in the port 110 is a camera module 120, and the number of the camera modules 120 is adjusted according to the product model. In this embodiment, two camera modules 120 are selected to provide a wider shooting angle and keep the port 110 smaller in size; a first optical fiber channel 130 is provided in the front tube 1, and the first optical fiber channel 130 forms an optical fiber end 131 at the port 110. The optical fiber end 131 is a lighting device for providing a light source. The optical fiber end 131 is placed on the upper part of the two camera modules 120 to evenly provide the two camera modules with a light source for image acquisition.

[0041] Furthermore, a heat dissipation pipe 140 is further provided in the front tube 1. The heat dissipation pipe 140 runs through the entire front tube 1. The heat dissipation pipe 140 is provided below the first optical fiber channel 130 to increase the air contact area, thereby improving the heat dissipation efficiency. Specifically, the heat dissipation pipe 140 is a metal tube, such as a copper tube, an aluminum tube, a stainless steel tube, etc.

[0042] Furthermore, a transparent end cover 111 is provided outside the port 110 to prevent the camera module from being contaminated.

[0043] The handheld part 2 is provided with a second optical fiber channel 210 and a third optical fiber channel 220. Specifically, the second optical fiber channel 210 and the third optical fiber channel 220 extend to the interior of the front tube 1 and then merge into the first optical fiber channel 130. The two optical fiber light guide channels at the front end can increase the surface area of ​​the optical fiber and the pipeline, improve the heat dissipation efficiency, and merge into one optical fiber channel at the rear end to centrally provide a light source to ensure the light intensity while reducing the volume of the front tube 1 and reducing the surgical trauma surface. Furthermore, the heat dissipation pipe 140 is provided below the second optical fiber channel 210 and the third optical fiber channel 220 to assist the light guide channel in heat dissipation.

[0044] Fiber bundles are provided in the first fiber channel 130, the second fiber channel 210 and the third fiber channel 220. Light generated by an external light source is transmitted to the fiber end 131 through the fiber bundle. The fiber end 131 emits strong light to illuminate the internal organs or tissues under observation.

[0045] Furthermore, a circuit board 250 is also provided in the handheld part 2, and the two ends of the circuit board 250 are respectively connected to a front-end signal line (not shown in the figure) and a rear-end signal line 240, the other end of the front-end signal line is connected to the camera module 120, and the other end of the rear-end signal line 240 is connected to the data line connector 6. Thus, the front-end signal line, the circuit board 250, the data line connector 6 and the rear-end signal line 240 together form a signal connection channel, and an image processor is also provided on the circuit board 250. The optical signal collected by the camera module 120 is converted into an electrical signal by the image processor for preliminary image processing, such as enhancing image display, filtering image magazines, etc., and finally the electrical signal is transmitted to an external display device connected to the data line connector 6.

[0046] Furthermore, a heat sink 230 is further provided in the handheld part 2, and the heat sink 230 is fixed on the circuit board 250. Specifically, the bottom surface of the heat sink 230 is fixed on the circuit board 250 by nuts or other conventional methods. The bottom surface of the heat sink 230 is rectangular or square, and the two bottom sides of the bottom surface adjacent to the handheld part 2 extend upward to form a raised portion, so that the heat sink 230 forms a structure with high sides and low middle. Specifically, the raised portion is a double-wing bend 231, and the second optical fiber channel 210 and the third optical fiber channel 220 pass through the bottom surface of the heat sink 230. The structure of the double-wing bend 231 greatly increases the surface area of ​​the heat sink 230, so that it can dissipate heat quickly. On the other hand, it can also assist the circuit board 250 in generating heat due to the photoelectric signal conversion of the image processor, and prevent the handheld part 2 from being locally overheated. Further, the heat sink 230 is made of metal material, such as copper, aluminum, stainless steel, etc.

[0047] Furthermore, the front-end signal line or the rear-end signal line 240 passes through the heat sink 230 and is connected to the circuit board 250 .

[0048] Specifically, the rear-end signal line 240 is led out from the data line connector 5, passes through the tee tube 4 and the rear tube 3, and then extends to the inside of the handheld part 2 to connect with the circuit board 250; the light guide channel is led out from the optical fiber connector 6 and forms a second optical fiber channel 210 and a third optical fiber channel 220 in the tee tube 4, and the second optical fiber channel 210 and the third optical fiber channel 220 pass through the heat sink 230 in the handheld part 3 and extend to the inside of the front tube 1 to merge into the first optical fiber channel 130 and form an optical fiber end 131 at the port 110.

[0049] When in use, connect the data cable connector 5 to the external imaging device, connect the optical fiber connector 6 to the external light source, insert the front tube 1 into the patient's body, start the light source switch, and the optical fiber end 131 provides a uniform light source for the camera module 120. The camera module 120 collects image signals and transmits them back to the external imaging device through the signal connection channel to provide reference for medical staff.

[0050] Example 2

[0051] Please refer to Figure 1-4 This embodiment provides a new type of laparoscope. As a further improvement on the first embodiment, the bottom surface of the heat sink 230 is rectangular or square, and the bottom edges of the bottom surface adjacent to the hand-held part 2 extend upward to form a convex portion. Specifically, the convex portion is an inclined surface 232. At the same time, the inner side of the inclined surface 232 is provided with evenly spaced strip-shaped protrusions 233, and the strip-shaped protrusions 233 are parallel to the bottom edge. The surface area of ​​the heat sink 230 is further increased by the arrangement of the strip-shaped protrusions, so that it can dissipate heat better.
