Description

Technical Field

[0001] This invention relates to the field of minimally invasive medical endoscope technology, and in particular to a detachable electronic endoscope based on a Type-C interface. Background Technology

[0002] Currently, most electronic endoscopes used in clinical practice adopt an integrated structure of the endoscope shaft and handle, which cannot be disassembled. The entire device must be sterilized after each use, which not only results in a long sterilization cycle and low equipment turnover efficiency, but also significantly increases the hospital's operating costs. At the same time, repeated sterilization of the endoscope can easily lead to problems such as water ingress into the seal and damage to the internal circuitry, greatly shortening the lifespan of the equipment.

[0003] Currently available detachable endoscopes are mainly optical endoscopes, which rely on the lens optical path for imaging. With long-term use, problems such as lens loosening, optical path misalignment, and blurred imaging are prone to occur, resulting in poor equipment operation stability.

[0004] Currently, the industry lacks a detachable electronic endoscope that combines clear and stable electronic imaging, no optical path deviation, independently detachable and sterilizable endoscope rod, simple structure, and low production cost, thus failing to meet the operating room's requirements for high efficiency, low loss, and high stability. Summary of the Invention

[0005] The purpose of this invention is to enable the quick separation of the handle and the endoscope pole, allowing the endoscope pole to be sterilized independently, while the handle only requires routine cleaning for reuse, thus ensuring electronic imaging quality and reducing equipment failure rate and clinical usage costs.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows:

[0007] A detachable electronic endoscope based on a Type-C interface includes a handle and a telescope rod detachably connected to the handle, as well as a fixing cover, a connecting cover, a transmission line, a rubber I-beam sleeve, a rubber sealing ring, a transmission pin, and a transmission plug.

[0008] The handle is provided with a Type-C interface socket, into which a matching Type-C interface plug is inserted; the transmission pin is inserted inside the handle, with one end of the transmission pin electrically connected to the Type-C interface socket and the other end abutting and connected to the transmission plug.

[0009] The end of the Type-C interface plug away from the Type-C interface socket is connected to the transmission line. A rubber I-beam sleeve is fitted on the outside of the transmission line. The fixing cover is fitted onto the outside of the rubber I-beam sleeve and is threaded to the outer wall of the left side of the handle.

[0010] The outer wall of the right side of the handle is threaded with a connecting cover, and a rubber sealing ring is sandwiched between the connecting cover and the mating surface of the handle to provide a sealing and waterproof function.

[0011] The scope rod integrates built-in wiring and a beam guide. One end of the built-in wiring is connected to a transmission plug, and the other end is connected to the beam guide. The scope rod is a fully sealed structure and can be sterilized independently.

[0012] As an improvement, a control motherboard is electrically connected to the built-in circuit.

[0013] As an improvement, a cover plate is fixedly installed inside the lens rod, and a rubber sealing ring is provided at the assembly gap between the cover plate and the lens rod to further ensure the overall sealing performance of the lens rod.

[0014] As an improvement, an adjustable universal joint is provided at the end of the outer wall of the telescope rod away from the transmission plug, which facilitates flexible adjustment of the observation field of view during surgery.

[0015] As an improvement, along the length of the telescope shaft, the beam guide, built-in circuitry, control board, and transmission plug are arranged sequentially from the side furthest from the handle to the side closest to the handle, resulting in a compact and reasonable overall layout.

[0016] As an improvement, the outer wall of the handle is integrally molded with anti-slip texture to enhance grip stability and prevent slippage during operation.

[0017] As an improvement, an image sensor is also integrated inside the endoscope pole. The image sensor is electrically connected to the built-in circuitry for acquiring intraoperative images.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. Breaking away from the traditional one-piece design of electronic endoscopes, the handle and endoscope rod are detachably connected, retaining the advantages of clear, stable imaging and no optical path deviation of electronic endoscopes. The imaging effect is far superior to that of traditional detachable optical endoscopes. The endoscope rod can be detached and sterilized independently, and the handle is exempt from repeated sterilization. This not only improves the turnover efficiency of operating room equipment, but also avoids damage to the internal circuitry of the handle due to sterilization, effectively reducing the hospital's use and maintenance costs.

[0020] 2. It adopts a single Type-C interface to realize mechanical docking, power supply and image signal transmission simultaneously. It has fewer parts, is easy to assemble and disassemble, has a low failure rate, and is suitable for large-scale mass production. It has rubber sealing rings in multiple places and a fully sealed design for the endoscope pole, which has good waterproof and sterilization resistance. The handle is equipped with anti-slip texture and the endoscope pole is equipped with a universal rod, which greatly improves the convenience and practicality of clinical operation.

Detailed Implementation

[0028] To make the content of this invention easier to understand, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0029] like Figures 1 to 5 As shown, this embodiment provides a detachable electronic endoscope based on a Type-C interface, mainly including a transmission line 1, a fixing cover 2, a rubber I-beam sleeve 3, an anti-slip texture 4, a handle 5, a connecting cover 6, a scope rod 7, a Type-C interface plug 8, a transmission plug 9, a control motherboard 10, a transmission pin 11, an image sensor 12, a beam guide 13, built-in wiring 14, a universal rod 15, a rubber sealing ring 16, a Type-C interface socket 17, and a cover plate 18.

[0030] The outer wall of the handle 5 is integrally molded with anti-slip texture 4, making it less slippery for medical staff when gripping and operating. A transmission pin 11 is installed inside the handle 5, and a Type-C interface socket 17 is opened on the handle 5. A matching Type-C interface plug 8 is inserted into the Type-C interface socket 17; one end of the transmission pin 11 is electrically connected to the Type-C interface socket 17, and the other end abuts against the transmission plug 9 to achieve electrical connection.

[0031] The Type-C interface plug 8 is connected to the transmission line 1 on the outside. A rubber I-beam sleeve 3 is fitted over the transmission line 1. A fixing cover 2 is fitted over the rubber I-beam sleeve 3 and is fixedly connected to the outer left wall of the handle 5 by threads. A connecting cover 6 is threaded onto the right side of the handle 5. A rubber sealing ring 16 is sandwiched between the mating surfaces of the connecting cover 6 and the handle 5 to achieve a waterproof seal at the connection.

[0032] The lens rod 7 is a fully sealed structure. The cover plate 18 is fixedly installed inside by bolts. A rubber sealing ring 16 is provided at the assembly gap between the cover plate 18 and the lens rod 7 to further enhance the sealing effect.

[0033] The internal structure of the lens rod 7 integrates a built-in circuit 14, a beam guide 13, a control main board 10, and an image sensor 12; the image sensor 12 and the control main board 10 are both electrically connected to the built-in circuit 14.

[0034] Along the length of the lens rod, inside the lens rod 7, from the side furthest from the handle 5 to the side closest to the handle 5, the beam guide 13, the built-in circuit 14, the control main board 10, and the transmission plug 9 are arranged in sequence.

[0035] An adjustable universal rod 15 is provided at the end of the outer wall of the endoscope rod 7 away from the transmission plug 9, which can flexibly adjust the intraoperative observation angle.

[0036] In this invention, the Type-C interface simultaneously performs three functions: mechanical docking and fixation, wired power supply, and image signal transmission. During operation, the power output from the handle 5 is transmitted through the Type-C interface socket 17, Type-C interface plug 8, transmission pin 11, transmission plug 9, and internal circuitry 14 to power components such as the image sensor 12 and control motherboard 10 inside the endoscope 7. The surgical image signal acquired by the image sensor 12 is transmitted back along the opposite path via wired transmission, ultimately completing the image output.

[0037] Usage and disassembly procedures

[0038] Before surgery, insert the Type-C connector 8 into the Type-C connector 17 to complete alignment and mechanical fixation. Then, tighten the fixing cover 2 and the connecting cover 6 in sequence to complete the assembly of the handle 5 and the endoscope pole 7. Medical staff hold the handle 5 and use the universal rod 15 to adjust the angle of the endoscope pole 7. The beam guide 13 provides illumination, and the image sensor 12 acquires images to complete the imaging work of the minimally invasive surgery.

[0039] After use, unscrew the fixing cap 2 and the connecting cap 6 in sequence, unplug the Type-C interface plug 8, and detach the endoscope 7 from the handle 5. Since the endoscope 7 has a fully sealed structure, it can be directly sent to a sterilization device for high-temperature or low-temperature sterilization; the handle 5 and its components only require routine cleaning with medical detergent and do not need sterilization. The sterilized endoscope 7 can be reassembled and used.

[0040] In this embodiment, the rubber sealing ring 16 and the rubber I-beam sleeve 3 are both made of medical-grade high-temperature and corrosion-resistant rubber material, and the Type-C interface is a medical waterproof interface. The whole system complies with the medical device usage specifications and sterilization requirements.

[0041] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
