Description

Technical Field

[0001] The present invention relates to the technical field of anorectal surgery, and in particular to a fixable light-guiding micro-rectoscope. Background Art

[0002] Anoscopes are commonly used tools for anorectal examinations. There are traditional anoscopes and electronic anoscopes. Traditional anoscopes are made of either disposable plastic or reusable stainless steel. Electronic anoscopes, on the other hand, utilize advanced medical video and camera technology to integrate both examination and treatment.

[0003] The primary function of an anoscope is inspection. Limited by the diameter of the anus and the scope, the intestinal lumen is insufficiently expanded, the surgical field is poorly exposed, and the operative distance is short. This makes it suitable only for simple procedures in the lower rectum and anus, and difficult to use for deeper and more complex procedures. Studies have shown that the resection rate of traditional transanal rectal tumor resection using an anoscope is 24%-42%. Endoscopic mucosal resection or endoscopic submucosal dissection is an alternative to colonoscopy. Single-point endoscopic procedures are difficult and require specialized equipment (injection needles, snares, hook blades, and IT blades). These procedures are expensive and difficult to clip, making them unsuitable for resection of larger lesions or full-thickness rectal resections. TEM technology, with its ingenious and sophisticated design, allows the surgeon to perform various laparoscopic procedures within the dilated intestine using the magnified, clear, three-dimensional vision provided by binoculars or the display of an endoscopic imaging system, along with sophisticated instruments. TEM technology requires expensive, imported equipment and requires prior laparoscopic or single-port laparoscopic surgery experience and specialized training, making it difficult to promote in primary care settings. TEM equipment is complex, connecting the equipment during surgery takes a long time, the binoculars are prone to fogging or being contaminated by intraoperative smoke, and wiping the lenses during surgery is time-consuming and laborious.

[0004] Therefore, the technical problems existing in the anoscope of the prior art are as follows: 1. Solving the problem of poor exposure of the visual field of the traditional anoscope; 2. No special instruments under the endoscope are required, and the cost is low; 3. The operation difficulty is lower than that of endoscopic ESD, which can expand the surgical indications of local rectal resection, can achieve full-thickness resection, and complete the suture closure of the wound; 4. There is no need to purchase TEM equipment and participate in training, the learning curve is short, the operation is simple, time-saving and labor-saving, and the external magnifying glass is not easy to be contaminated or fogged; 5. It uses a fixed bracket, has its own light source, and the device is easy to install. It can be operated by one person without an assistant; 6. It magnifies the high-definition visual field and can complete microscopic operations. The magnifying glass is detachable, and whether to install and use it depends on the intraoperative situation; 7. Made of 304 stainless steel, it is resistant to high-temperature disinfection.

A socket 307 is provided at the end of the lens ring 305 away from the inner core buckle 306. The socket 307 is in a pin-shaped structure and is arranged on the same side of the lens ring 305. There are three sockets 307, and a screw hole 308 is provided on the surface of the lens ring 305.

[0033] Furthermore, the diameter of the inner core 302 is the same as the inner diameter of the proctoscope 301, the diameter of the handle 303 is the same as the diameter of the lens ring 305, the diameter of the lens ring 305 and the inner diameter of the proctoscope 301 are arranged from large to small, and the connection is arranged in an arc-shaped structure. The end of the proctoscope 301 away from the lens ring 305 is provided with an arc-shaped brim structure, and a bevel structure is added, and the bevel angle is forty-five degrees.

[0034] The magnifying glass 4 includes a mirror body 401 and a mirror frame 402. The mirror frame 402 is installed on the edge of the upper surface of the mirror body 401. The mirror frame 402 and the mirror body 401 are connected by a fastening bolt 403, and the fastening bolt 403 includes a rotating shaft for rotating the mirror body 401 inside the mirror frame 402. A mirror handle 404 is installed in the middle of the top of the mirror frame 402, and a mirror base 405 is installed at the top of the mirror handle 404. A fixing bolt 406 is provided at the top of the mirror base 405. The mirror base 405 includes a rod-like structure, and an external screw 407 is provided at one end of the rod-like structure.

[0035] The light guide system 5 is arranged in an L-shaped structure, including a main body plate 501. A suction tube 502 and an illumination tube 503 are arranged on the outer surface of the main body plate 501. A right-angle groove 504 is provided near the bend of the main body plate 501. The horizontal part of the main body plate 501 is arranged in an arc-shaped structure. The mouth of the suction tube 502 is arranged at the front end of the illumination tube 503, and the head end of the illumination tube 503 is inclined at 10-15 degrees to the horizontal part of the main body plate 501.

[0036] A straight groove 6 is provided on the inner side of the lens ring 305, and the right-angle groove 504 is provided corresponding to the straight groove 6. A fastener 601 is provided on the inner side of the main rod 503, and the fastener 601 is used to form a snap connection with the lens ring 305. A fixing plate 602 is provided on the top side of the fastener 601, and a long screw 603 passes through the middle of the top of the fixing plate 602. A groove 604 is provided on the inner surface of the main rod 503, and the fastener 601 is slidably provided in the groove 604.

[0037] The proctoscope 301, support frame 101, universal shaft 102, bedside fixture 1 and light guide system 5 are all made of 304 stainless steel. The latch 304 and the inner core buckle 306 are arranged in corresponding positions, wherein the inner core buckle 306 has an inward concave structure, and the shape of the latch 304 corresponds to the inner core buckle 306.

[0038] The universal ball at the clamping head 103 is movably connected to the universal shaft 102. The steering ball at the universal shaft 102 is arranged in a spherical universal joint structure. The penetrating screw 202 is used to frictionally fix and limit the steering ball 2. The top of the clamping head 103 is provided with a C-shaped clamping structure.

[0039] Specifically, its overall structure mainly consists of a bedside fixture 1, a support frame 101, a universal shaft 102 and a clamping head 103. Figure 1-2 As shown, the spherical node 104 is mainly composed of a steering ball 2, a support rod 201, a through screw 202 and a limit bolt 203. This structure can adjust the angle of the universal shaft 102 and the rotation angle of the clamping head 103 during surgery. At the same time, the control structure of the spherical node and the universal rod of the TEM are the same. Both ends can be fixed after the middle is rotated, or the spherical node 104 itself uses a transmittable soft shaft, which can control the nodes at both ends to complete the synchronous fixation effect. It can form an extrusion-type fixation effect according to the patient's lying posture before surgery. Especially when used in conjunction with the rectoscopy 301 structure, the simple assembly structure of the overall structure can more quickly build a surgical stent for operation.

[0040] The proctoscope 301 is fixed by the handle 3 and the clamping head 103. The clamping head 103 forms a steering function based on the universal ball and the spherical node 104. The corresponding inner core 302 structure is provided on the proctoscope 301. The inner core 302 includes a handle 303 and a latch 304 structure. When in use, it corresponds to the lens ring 305 on the proctoscope 301. Figure 3-4 The inner core buckle 306 structure at the inner core completes the buckling function. When the proctoscope 301 is placed in the patient's body, the medical staff can rotate the inner core 302 in the opposite direction of the inner core buckle 306 to release the locking function and remove the inner core 302. Since the inner core 302 is completely embedded in the body of the proctoscope 301, the gap is extremely small, which facilitates insertion into the rectum and reduces mucosal damage.

[0041] The proctoscope 301 has a 4cm outer diameter and is 16cm long, providing a wider and deeper operating space. A brim design with a 45° bevel at the front end prevents intestinal wall collapse from affecting the field of view, increases the space above the field of view, and facilitates surgery. The handle 303 of the body connects to the clamping head 103 to maintain stability during surgery. The handle is thicker and easier to grasp. The light guide system 5 can be fixed to the lens ring 305. The inner core 302 can be locked with the body by rotating it clockwise to prevent the inner core from moving and damaging the rectum when the body is inserted into the rectum. The inner core 302 can be unlocked by rotating it counterclockwise.

[0042] There are three jacks 307 for fixing the magnifying glass on the surface of the lens ring 305. The magnifying glass is placed right on top as much as possible. The magnifying glass 4 is mainly composed of a lens body 401, a lens frame 402, a lens handle 404 and a lens base 405. The lens base 405 includes the following components: Figure 9 The mirror body 401 is fixed on the mirror ring 305 by the screw thread 407, and the mirror body 401 is fixed on the mirror ring 305 by the screw thread 407.

[0043] A light guide system 5 is provided on the lens ring 305. The light guide system 5 includes a main body plate 501. A suction tube 502 and an illumination tube 503 are provided on the outer surface of the main body plate 501. The light guide system 5 is arranged in a front-to-back direction in the outlet direction. The front suction tube 502 is used to absorb smoke. The light from the illumination tube 503 provided at the rear can form an illumination effect inside the proctoscope 301. At the same time, it can cooperate with the brim structure at the front to complete light shielding, and the light can complete a diffuse reflection lighting effect inside the proctoscope 301 to increase the technical effect of internal brightness. At the bend of the light guide system 5, a right-angle groove 504 is provided, which can correspond to the straight groove 6 structure of the lens ring 305. That is, the light guide system 5 is fixed to the edge of the lens ring 305 according to the fastener 601. A fixing plate 602 is further provided on the top side of the fastener 601. Figure 6 As shown, a long screw 603 is provided on the surface of the fixing plate 602. When the long screw 603 passes through the fixing plate 602 to the fastener 601, the long screw 603 squeezes the fastener 601 downward by rotating. At the same time, the fastener 601 is arranged in an arc-shaped structure with protruding edges, so that the light guide system and the mirror ring 305 are clamped and fixed.

[0044] Its overall structure is simple, with a support frame 101, a universal shaft 102 and a clamping head 103 as an integrated structure, which is connected to the operating bed through a bedside fixture 1. After fully exposing the lesion, the clamping head 103 is connected to the gripping handle 3 while keeping the mirror body stable. Finally, the limit bolt 202 of the spherical node 104 of the universal shaft 102 is tightened, and a light guide system 5 with light guide and suction functions is provided. The width is 2.5 cm, and the interface can be connected to a cold light source light guide and a negative pressure suction device at the same time. The front end of the suction pipeline is located just above the operating area and a side hole is added. The head end of the light guide pipeline is outward and tilted 10-15 degrees to better provide intraoperative lighting and remove intraoperative smoke, providing a good field of view. The light guide interface and the negative pressure suction tube interface are at different heights for easy connection. The shape of the light guide system 5 is completely matched with the mirror body and has a snap-on design for easy fixation to the mirror body and to prevent it from falling off during surgery.

[0045] The magnifying glass 4 is 3 cm in diameter and provides 3-10x magnification for a clearer field of view. The lens ring 305 has three fixed positions (10 o'clock, 12 o'clock, and 2 o'clock) and is secured to the body of the proctoscope via external screws 407. The lens base 405 of the magnifying glass 4 rotates 360°, allowing for easy adjustment to the optimal angle. The magnifying glass 4 is located outside the proctoscope 301, away from the surgical field, to prevent eyepiece contamination and fogging. The magnifying glass 4 is detachable and can be installed or used depending on the surgical situation.

[0046] At the same time, the overall structure is easy to disassemble and install, and is easier to learn how to use and teach. Especially in the actual surgical process, it can directly improve the work efficiency of preoperative preparation. The overall structure does not have a large number of electronic component structures, making it easier to repair and maintain, and has the actual effect of reducing the failure rate.

[0047] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
