Description

Technical Field

[0001] The invention relates to a uterine fibroid ultrasonic inspection device used in laparoscopic surgery, belonging to the technical field of medical equipment. Background Art

[0002] Since uterine fibroids are multiple and can grow in any part of the uterus, they are mainly divided into intramural fibroids, subserosal fibroids, and submucosal fibroids according to the location of the fibroids. In practical applications, laparoscopy is mainly used to remove subserosal fibroids located on the outer surface of the uterus and intramural fibroids located between the uterine muscle walls, while submucosal fibroids located in the uterine cavity are more suitable for resection through hysteroscopy. However, due to the lack of tactile sensation during laparoscopic surgery, even if the preoperative ultrasound indicates the presence of uterine fibroids within the uterine muscle wall and not protruding under the serosa, it is difficult for the surgeon to detect and locate them during the operation, resulting in incomplete fibroid resection and residual fibroids. Therefore, laparoscopic myomectomy has certain limitations.

[0003] A Chinese patent with publication number CN107569277A discloses a hysteroscopic uterine fibroid removal system, which controls a vibration device to drive a camera to vibrate periodically and collect images inside the uterus, thereby expanding the image range of the collection inspection area and increasing the surgical field; however, this method can only observe and remove visible uterine fibroids, and it is difficult to detect intramural fibroids that are invisible under laparoscopy, resulting in incomplete fibroid removal and partial residual fibroids.

[0021] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0022] like Figure 1-2 As shown, a uterine fibroid ultrasound examination device used in laparoscopic surgery comprises an examination rod 1, one end of which is provided with an ultrasound probe 2 for ultrasound examination of the uterine wall, the ultrasound probe 2 can swing circumferentially relative to the end of the examination rod 1, the end of the ultrasound probe 2 is provided with an inclined surface 21 in contact with the uterine wall, the inclined surface 21 is arranged in a concave structure, the inclination angle of the end face of the ultrasound probe is 45 degrees, which can increase the contact area between the end face of the ultrasound probe and the inner wall of the uterus, so that the hidden uterine fibroids can be better fitted to the inner wall of the uterus for examination, and the outer walls of the examination rod 1 and the ultrasound probe 2 are tightly wrapped with an elastic sleeve 3. The outer diameter of the inspection rod 1 is not less than the maximum outer diameter of the ultrasonic probe 2; the above-mentioned ultrasonic probe is a product currently available on the market and is a prior art, which will not be described in detail here. The ultrasonic probe can be connected to an external device by passing a line through the inspection rod, or it can be set up with a wireless ultrasonic probe currently available on the market. The surface of the end of the ultrasonic probe in contact with the uterine wall is set as an inclined surface that matches the uterine wall and is concave, so as to more fully contact the uterine wall to inspect the invisible uterine fibroids inside it. The above-mentioned elastic sleeve is made of medical grade silicone or rubber material, which is completely covered on the surface of the ultrasonic probe and the inspection rod and is completely closed. And it can be sterilized many times for reuse. The end of the elastic sleeve is a structure that matches the shape of the ultrasound probe. The end face of the elastic sleeve is in close contact with the inclined surface of the end of the ultrasound probe. The outer diameter of the inspection rod is greater than or equal to the maximum outer diameter of the ultrasound probe, so that when the ultrasound probe passes through the laparoscopic incision, the inspection rod can pass through and extend into it, so as to avoid the inspection rod being unable to pass through the laparoscopic incision and the inspection rod being unable to enter the laparoscopic incision due to its large outer diameter or affecting normal use. The inspection rod can be easily extended into the laparoscopic incision and close to the uterine wall, so that the invisible uterine fibroids can be inspected and explored through the ultrasound probe at the end, so as to avoid improper myoma removal. The ultrasonic probe is completely fitted with the uterine wall, and the position change of the inspection rod relative to the uterine wall can be adapted to the swing of the ultrasonic probe, so that the ultrasonic probe always keeps fitting with the uterine wall, thereby ensuring that the contact between the ultrasonic probe and the uterine wall is full and comprehensive, and the inspection of uterine fibroids is more accurate and comprehensive. The elastic sleeve is convenient for wrapping the ultrasonic probe and the inspection rod to play an isolation and protection role, so as to facilitate the disinfection of the device and avoid the detachment or corrosion of parts, and the ultrasonic probe can be rotated under the wrapping of the elastic sleeve, which is more convenient to use.

[0023] like Figure 2-6 As shown, a sphere 22 is provided at one end of the ultrasonic probe 2 connected to the end of the inspection rod 1, a spherical groove 11 is provided at the end of the inspection rod 1 to match the sphere 22, the sphere 22 and the ultrasonic probe 2 are integrally formed, an annular groove 12 is provided on the end surface of the inspection rod 1 corresponding to the spherical groove 11, an annular wall 13 is formed between the spherical groove 11 and the annular groove 12, a plurality of evenly distributed and upwardly open notches 131 are provided on the annular wall 13, the depth of the spherical groove 11 is greater than the radius of the sphere 22, a plurality of equally spaced telescopic springs 14 are provided between the bottom surface of the ultrasonic probe 2 and the end surface of the inspection rod 1, the telescopic springs 14 are distributed around the sphere 22, a plurality of grooves 15 corresponding to the telescopic springs 14 are provided on the end surface of the inspection rod 1, one end of the telescopic spring 14 is located in the groove 15, and the other end of the telescopic spring 14 contacts with the ultrasonic probe 2, the arrangement of the above-mentioned sphere and the spherical groove facilitates the connection between the ultrasonic probe and the end of the inspection rod, so that The ultrasonic probe can be rotated circumferentially relative to the end of the inspection rod to adapt to the position change of the inspection rod relative to the uterine wall, and the assembly is simple. The annular wall formed between the annular groove and the spherical groove can support and limit the sphere to prevent the ball head from rotating circumferentially under the support of the annular wall. The setting of the notch makes the annular wall have elastic deformation ability, increases the clamping ability of the sphere, and strengthens the limiting effect on the sphere. The depth of the above-mentioned spherical groove is greater than the radius of the sphere, so that the spherical groove is limited to the sphere, avoiding the sphere from easily escaping from the spherical groove and ensuring the normal rotation of the sphere in the spherical groove. The above-mentioned telescopic spring is arranged between the bottom surface of the ultrasonic probe and the end surface of the inspection rod, so that the ultrasonic probe can automatically return to its original position after use and maintain the normal rotation effect of the ultrasonic probe. The groove is used to accommodate the telescopic spring, limit the telescopic spring, avoid the telescopic spring displacement and cause the ultrasonic probe to be unable to reset, and facilitate the assembly of the telescopic spring.

[0024] The sphere arranged at the bottom end of the ultrasonic probe just fits into the spherical groove, and the opening edge of the spherical groove is located at the upper half of the sphere. The spherical groove can surround most of the sphere, ensuring that the sphere can rotate freely while limiting the position of the sphere. The notch in the annular wall allows the annular wall to deform when the sphere is inserted, thereby limiting the position of the sphere and facilitating the assembly of the sphere. Multiple telescopic springs are evenly distributed around the circumference of the sphere, and grooves are arranged on the circumference of the annular groove. The telescopic spring is directly placed in the groove, and the upper end of the telescopic spring contacts the bottom of the ultrasonic probe, and the lower end of the telescopic spring contacts the bottom surface of the groove. When the ultrasonic probe swings, the telescopic spring can be squeezed and returns to its original state at the end of use. Other elastic parts that can play a resetting role can be placed in the groove to replace the telescopic spring.

[0025] like Figure 4-5As shown, an annular protrusion 16 is provided on the side wall of the inspection rod 1 at a position close to the end that does not contact the ultrasonic probe 2, and an annular limiting portion 17 is provided at the edge of the annular protrusion 16. The bottom of the annular limiting portion 17 protrudes from the annular protrusion 16, and also includes an isolation sleeve 4 that can wrap the device and fit tightly with the elastic sleeve 3. A tightening ring 41 that cooperates with the annular limiting portion 17 is provided at the opening edge of the isolation sleeve 4. The coordinated setting of the above-mentioned annular protrusion and the annular limiting portion can cooperate with the elastic sleeve to form a bulge, thereby limiting the opening of the isolation sleeve to prevent the isolation sleeve from being disengaged, making it more convenient to use. The isolation sleeve can isolate the elastic sleeve, and the isolation sleeve can be replaced immediately to ensure the safety and hygiene of the device, and can be replaced after the probe is disinfected. To achieve repeated use, the tightening ring can cooperate with the annular limiting part to form a positioning, and the opening of the isolation sleeve is clamped on the annular limiting part through the tightening ring to form a fixation; the above-mentioned annular convex portion is formed on the side wall of the inspection rod, and the annular limiting part is formed at the edge of the annular convex portion. When the elastic sleeve wraps the inspection rod, the position where the annular limiting part is located lifts up the elastic sleeve to form a bulge, and the opening edge of the isolation sleeve can be clamped on the bulge formed by the annular limiting part lifting the elastic sleeve through the tightening ring to fix the isolation sleeve. The end of the isolation sleeve is a structure that matches the shape of the ultrasonic probe, and the end face of the isolation sleeve is close to the inclined surface of the end of the ultrasonic probe. The isolation sleeve is made of a material similar to that of a condom and is a disposable item. It is discarded after a single use and the device is disinfected and stored.

[0026] The tail end of the inspection rod is provided with a gripping portion for the doctor to grasp conveniently, and a connecting line is arranged at the tail end of the gripping portion. The device is connected to an external ultrasound machine through the connection and is compatible with existing ultrasound machines.

[0027] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention may also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
