Description

Technical Field

[0001] The invention relates to the technical field of uterine fibroid rotary cutting, and in particular to a uterine fibroid rotary cutting device. Background Art

[0002] Uterine fibroids are benign growths of the smooth muscle tissue of the uterus. The disease primarily affects women between 30 and 50 years old, although it is less common in people under 20 years old, but it can still occur. Potential patients may have no obvious symptoms, but the disease is discovered through physical examination.

[0003] With the development of modern medicine, laparoscopic surgery has the advantages of less trauma and faster recovery, and has been widely used in gynecological clinics. Laparoscopic myomectomy is to open a 1-5CM hole in the abdominal wall, through which the instrument enters the abdominal cavity, peels off the uterine fibroid nodules, and removes the fibroids through this hole. However, when the diameter of the fibroid is relatively large (more than 5CM), it is impossible to remove the entire uterine fibroid through the abdominal wall hole. Therefore, myomectomy is used to cut the uterine fibroid into strips and blocks, and then the strips and blocks are taken out separately through the drill tube until the entire uterine fibroid is cut.

[0004] However, it is difficult to determine whether some uterine fibroids are benign fibroids before surgery. This type of laparoscopic uterine fibroid excision is likely to cause fragments of the uterine fibroids to scatter in the abdominal and pelvic cavity during the excision process, which may cause implantation and dissemination. If the uterine fibroid is a malignant uterine sarcoma, excision in the abdominal cavity will increase the incidence of implanted cancer. And during the operation, a four-legged grasping forceps is used to tightly grasp the uterine fibroid nodule tissue, an assistant assists in fixing the position of the fibroid, and the operator uses a fibroid drill to cut the uterine fibroid tissue. This fixing method has poor stability and can only excise very small pieces of tissue at a time, making the entire operation time-consuming and laborious. Therefore, the present application provides a uterine fibroid exciter to meet the needs. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a uterine fibroid exciser to solve the problems that the current uterine fibroid exciser is easy to spread and implant, is inconvenient to fix, can only excise very small pieces of tissue at a time, and the whole operation is time-consuming and laborious.

[0011] Optionally, a bent portion is provided at the bottom end of the main frame, and weakened grooves are provided on both sides of the bent portion.

[0012] Optionally, a first end portion is provided at the bottom end of the main frame, and a first weakened portion matching the shape of the second end portion is provided on the first end portion.

[0013] Optionally, a second weakened portion is provided on the second end portion, and a guide portion is fixedly connected to an outer wall of one side of the second end portion close to the first end portion, and the guide portion is provided with hollow grooves at equal intervals.

[0014] Optionally, a first limit block is fixedly connected to the bottom of the outward rotating rod, and a second limit block whose shape matches that of the first limit block is fixedly connected to the bottom of the pull rod.

[0015] Optionally, a spiral first rotating piece is fixedly connected to the bottom of the inner rotating rod, hook pieces are equidistantly arranged in an annular shape on the bottom of the inner rotating rod, and closing grooves are equidistantly arranged in an annular shape on the bottom of the inner rotating rod.

[0016] Optionally, a concave portion is provided at the bottom of one group of the main skeletons, and a convex portion is provided on another group of the main skeletons, and third weakened portions are provided on both sides of the concave portion and the convex portion.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above scheme, by setting up the opening mechanism, not only can the uterine fibroids cut from the uterine wall be bagged, but the bag mouth can also be quickly sealed, so that the uterine fibroids are placed in an independent space for rotary cutting, avoiding the spread of malignant tumors during the cutting process, and the setting of the external rotating rod and the second rotating blade can stably fix the tumor during the rotary cutting process, making the rotary cutting operation more convenient, and the coordinated use of various structures in the opening mechanism makes the use of the device more convenient and quick.

[0019] By arranging a main frame and an auxiliary frame in the opening mechanism, the main frame and the auxiliary frame only need to be pushed downward from the connecting pipe so that the main frame and the auxiliary frame can be rapidly expanded to a natural state due to their own elastic force, so that the storage bag can be stretched open, and a larger operating space can be formed in the storage bag. In addition, the main frame and the auxiliary frame are arranged on the inner wall of the storage bag, so that when the rotary cutting operation is performed in the storage bag, the main frame and the auxiliary frame protect the storage bag, so that the rotary cutting blade will not accidentally touch the storage bag during the rotary cutting process. The arrangement of this structure makes the opening mechanism safer when in use, and leaves a sufficiently large operating space for the device to facilitate the rotary cutting work of medical staff.

[0020] By arranging an external rotating rod, an internal rotating rod and a pull rod in the opening mechanism, the removed tumor can be fixed on the external rotating rod, so that the tumor can be stably set in one position without sliding during the peeling operation. The structure makes the operation of medical staff more convenient, and the use of the pull rod in conjunction with the main frame makes it easy to tighten the storage bag. By rotating the internal rotating rod, the structure at the bottom of the internal rotating rod can also hook the storage bag and twist the opening of the storage bag, making the subsequent sealing operation at the opening of the storage bag more convenient and improving the sealing effect of the opening of the storage bag.

[0021] By providing a first end, a second end and a guide portion in the opening mechanism, the ends of the main frame and the pull rod can be connected together by rotation, and the shape design of the first end and the second end makes the connection between the main frame and the pull rod more stable. The guide portion can be deformed by being squeezed during the rotational connection between the first end and the second end, and the opening of the guide portion on the side away from the second end is larger, which plays a good guiding role in the rotational connection operation. The structure further makes the use of the opening mechanism more convenient.

[0022] By providing a concave portion and a convex portion in the opening mechanism, after the inner rotating rod rotates and tightens the opening of the storage bag in the first step, the two sets of main skeletons are tightened, and the extrusion force generated by the deformation of the concave portion and the convex portion is used to squeeze the opening of the storage bag, so that the opening of the storage bag can be quickly sealed, thereby forming a sealed cavity in the storage bag. The structure further makes the sealing operation of the unfolding mechanism quick and convenient.

[0023] To sum up, through the coordinated use of various parts inside the opening mechanism, not only can the main frame and the auxiliary frame open the storage bag quickly, so that there is enough operating space in the storage bag, the removal operation of the uterine fibroids in the storage bag is more convenient, and the problem of the storage bag breaking during cutting is prevented. In addition, the coordinated use of the main frame and the external rotation rod makes the stability of the two better, and during the rotary cutting operation, the uterine fibroids are further stably set in the desired position, thereby making the rotary cutting work of medical staff more convenient. The device has a simple structure, low production cost, good practicality, and is easy to produce and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The bottom of the single-hole laparoscope port 1 is set at the patient's skin incision, the grasping forceps body 2 is inserted into the mechanical entry port in the single-hole laparoscope port 1, and the connecting pipe 3 is inserted into a mechanical entry port in the single-hole laparoscope port 1. The built-in bag 4 is a thin film bag made of plastic material. The storage bag 4 is spherical when opened. The bottoms of the two groups of main skeletons 5 form an eight-shaped shape. The main skeleton 5 and the auxiliary skeleton 21 are equidistantly distributed at the bottom of the connecting pipe 3. The inner rotating rod 7 and the outer rotating rod 6 are rotatably connected. The bottom of the inner rotating rod 7 is provided with an end block, and the hook piece 25 is arranged on the end block at the bottom of the inner rotating rod 7. The first rotating piece 24 is wider on the side close to the inner rotating rod 7. 24 is narrower on the side away from the inner rotating rod 7, the first rotating blade 24 and the second rotating blade 27 are made of stainless steel, the main frame 5 and the side frame 20 are integrally formed, the cross-section of the first limiting ring 16 is trapezoidal, and the side of the first limiting ring 16 close to the first rotating blade 24 is narrower, and the six groups of second rotating blades 27 are spirally distributed on the outer wall of the outer rotating rod 6, the outer wall edge of the guide portion 12 is arc-shaped, and the pull bar 8 passes through the second limiting ring 17 and the first limiting ring 16 at the same time. The shape of the receiving groove 18 is adapted to the shape of the first end 10 and the second end 11, the shape of the limiting groove 19 is adapted to the shape of the bending portion 9, and the inner wall of the limiting groove 19 is provided with a rubber pad.

[0047] Through the opening mechanism, not only can the storage bag 4 be opened quickly, so that the size of the cavity in the storage bag 4 can be adapted to the rotary cutting operation of medical staff, but also the problem that the existing plastic bags are easily damaged during use is solved, so that the device is safer during use and the spread and implantation of tumors are effectively prevented. In addition, the opening mechanism can also assist in fixing uterine fibroids, further facilitating the rotary cutting work of medical staff in the cavity of the storage bag 4, making the rotary cutting more stable, thereby making the work efficiency of uterine rotary cutting higher and the practicability of the device better.

[0048] like Figures 3 to 6 As shown, the opening mechanism includes a main frame 5 installed on the connecting pipe 3, a side frame 20 is fixed on the main frame 5, an auxiliary frame 21 is arranged in the connecting pipe 3, the main frame 5, the side frame 20 and the auxiliary frame 21 are made of steel wire material, the cross-sections of the main frame 5 and the auxiliary frame 21 are C-shaped, the side frame 20 has an arc-shaped structure away from the main frame 5, the area of ​​the main frame 5 is larger than the area of ​​the auxiliary frame 21, a group of main frames 5 has a recess 28 at the bottom, and another group of main frames 5 has a protrusion 29, and a third weakened portion 30 is opened on both sides of the recess 28 and the protrusion 29.

[0049] By setting the main frame 5, the side frame 20 and the auxiliary frame 21 in the connecting pipe 3, the above three are folded in the cavity of the connecting pipe 3 when not in use, and the storage bag 4 is attached to the outer wall of the main frame 5 and the auxiliary frame 21 and folded in the cavity of the connecting pipe 3. When the uterine fibroids are cut off from the inner wall of the uterus, it is only necessary to push the main frame 5 and the auxiliary frame 21 downward, and the main frame 5, the side frame 20 and the auxiliary frame 21 will naturally open, so that the storage bag 4 will open accordingly, so that a cavity is formed in the storage bag 4 to facilitate the placement of the uterine fibroids. The steel wire material has good deformation ability, good support and strong stability, which further facilitates the folding and unfolding of the main frame 5, the side frame 20 and the auxiliary frame 21, and the side frame 20 is set to assist in supporting and limiting the uterine fibroids. , so that the uterine fibroid is located at the center of the cavity of the storage bag 4, and further, during rotary cutting, the blade will not accidentally hit the storage bag 4 and cause the storage bag 4 to rupture, and the arc-shaped side frame 20 also has a certain elasticity, so that when the uterine fibroid enters the storage bag 4, the side frame 20 can provide certain auxiliary guidance and will not puncture the uterine fibroid, and the main frame 5 has a larger area and better support, and at the same time facilitates the rotational connection between the first end 10 and the second end 11. The shapes of the concave portion 28 and the convex portion 29 arranged on the main frame 5 are adapted to each other, so that the two are squeezed against each other when pulled, thereby quickly sealing the opening of the storage bag 4, and the setting of the third weakened portion 30 makes it easier for the concave portion 28 and the convex portion 29 to deform, thereby achieving a better squeezing and sealing effect of the two.

[0050] like Figure 3 and Figures 6 to 11 As shown, an external rotating rod 6 is provided in the connecting pipe 3, an internal rotating rod 7 is provided in the external rotating rod 6, a pull rod 8 is provided in the connecting pipe 3, the bottom end of the pull rod 8 is fixedly connected to the second end 11, the bottom outer wall of the external rotating rod 6 is fixedly connected to the first limiting ring 16, the external rotating rod 6 is fixedly connected to the second limiting ring 17, a receiving groove 18 is provided at the bottom of the external rotating rod 6, a limiting groove 19 is provided at the bottom of the external rotating rod 6, and the outer wall of the external rotating rod 6 is annularly equidistantly provided with second rotating plates 27, the bottom end of the main skeleton 5 is provided with a first end 10, the first end 10 is provided with a first weakened portion 13 whose shape matches the second end 11, the bottom of the external rotating rod 6 is fixedly connected to a first limiting block 22, and the bottom of the pull rod 8 is fixedly connected to a second limiting block 23 whose shape matches the first limiting block 22.

[0051] By setting the external rotation rod 6 and the second rotating piece 27, the external rotation rod 6 drives the second rotating piece 27 to rotate toward the uterine fibroids, so that the uterine fibroids can be quickly fixed on the external rotation rod 6. Fig. 9 and Fig.10The second rotary blade 27, which is equidistant and divergent in shape of barbs, allows the uterine fibroid to be more stably arranged on the external rotation rod 6, making the rotary cutting operation more convenient, and the pull bar 8 is arranged on the outer wall of the external rotation rod 6 and is not connected to the external rotation rod 6. By pushing the pull bar 8, the pull bar 8 can drive the second end 11 to move squarely toward the first end 10. The second limiting ring 17 and the first limiting ring 16 are used to limit the pull bar 8. Figure 6 As shown, the pull strip 8 at the top of the first limiting ring 16 is in a straight line and fits the outer wall of the outward rotating rod 6, and the pull strip 8 at the bottom of the first limiting ring 16 is naturally bent and expanded, and the first limiting block 22 and the second limiting block 23 limit the pull strip 8, so that the pull strip 8 extends downward until the first end 10 and the second end 11 are just aligned and stop, and then the pull strip 8 is rotated to make the second end 11 stuck in the first end 10, so that the main frame 5 and the pull strip 8 are connected, so that it is convenient for the pull strip 8 to pull the main frame 5 to drive the opening of the storage bag 4 to tighten, which is convenient for subsequent sealing operations, and the setting of the first weakened portion 13 makes the first end 10 easy to deform, so that the second end 11 and the first end 10 are connected more quickly and the tightness of the connection is better, as shown in FIG. Fig.12 As shown, by squeezing the receiving groove 18 and the protrusion 29, the opening of the storage bag 4 can be quickly sealed, so that the storage bag 4 creates a closed space for uterine rotational resection. The coordinated use of the structures further improves the use effect of the device.

[0052] like Figure 5 and Figures 8 to 11 As shown, a bending portion 9 is provided at the bottom end of the main skeleton 5, weakened grooves are provided on both sides of the bending portion 9, a second weakened portion 14 is provided on the second end portion 11, a guide portion 12 is fixedly connected to the outer wall of one side of the second end portion 11 close to the first end portion 10, and hollow grooves 15 are equidistantly provided on the guide portion 12, a spiral first rotating piece 24 is fixedly connected to the bottom of the inner rotating rod 7, hook pieces 25 are equidistantly provided in a ring shape at the bottom of the inner rotating rod 7, and closing grooves 26 are equidistantly provided in a ring shape at the bottom of the inner rotating rod 7.

[0053] The second end portion 11 is more easily deformed by the arrangement of the second weakened portion 14, and the connection between the first end portion 10 and the second end portion 11 is further facilitated by the guidance of the guide portion 12. The bent portion 9 is affected by the above-mentioned pull rod 8 and the main skeleton 5, and can be quickly clamped into the limiting groove 19, so that the pull rod 8 and the main skeleton 5 have a good limiting effect on the end of the external rotation rod 6, further improving the stability of the external rotation rod 6 and facilitating the peeling work. In addition, the hollow groove 15 arranged on the guide portion 12 allows the guide portion 12 to be deformed when used for guiding, further facilitating the guiding use of the guide portion 12, such as Figure 4The setting of the first rotating piece 24 shown makes it easier for the uterine fibroid to be rotated from the end of the inner rotating rod 7 to the outer rotating rod 6, and the hook piece 25 is retracted into the retracting groove 26 when subjected to the pressure generated by the approaching uterine fibroid, so that the hook piece 25 will not block the rotation of the uterine fibroid. When the uterine fibroid completely penetrates the inner rotating rod 7, the hook piece 25 rebounds to facilitate the subsequent hooking of the opening of the storage bag 4 to close the opening of the storage bag 4, and the structure is simple, which further improves the use effect of the device.

[0054] The working principle of the technical solution provided by the present invention is as follows:

[0055] During the single-port hysterectomy minimally invasive surgery, a small incision is first made at the navel, and then the single-port laparoscope port 1 is fixed to the patient's navel, and then the grasping forceps body 2 and the connecting pipe 3 are inserted from the top of the single-port laparoscope port 1, and the rotary cutter is inserted into the single-port laparoscope port 1, and the uterine fibroids are grasped by the grasping forceps body 2, and then the uterine fibroids are removed from the inner wall of the uterus by the rotary cutter, and then the grasping forceps body 2 continues to grasp the uterine fibroids, and the main frame 5 and the auxiliary frame 21 are pushed downward from the connecting pipe 3, so that the bottom of the main frame 5 and the auxiliary frame 21 are naturally unfolded, and at the same time, the side frame 20 is expanded, and the storage bag 4 is unfolded accordingly, and the opening of the storage bag 4 is opened. The mouth is opened, and then the external rotation rod 6 and the internal rotation rod 7 are extended out from the connecting pipe 3, and the uterine fibroids are squeezed toward the opening of the storage bag 4 by using the grasping forceps body 2. The bottom of the main frame 5 and the auxiliary frame 21 guide the entry of the uterine fibroids, and under the action of the squeezing force, the bottom of the main frame 5 and the auxiliary frame 21 expand outward, and the uterine fibroids are entered into the cavity of the storage bag 4 with the continuous pushing of the grasping forceps body 2. At this time, the grasping forceps body 2 continues to clamp the uterine fibroids to limit the position of the uterine fibroids, and then the external rotation rod 6 and the internal rotation rod 7 are rotated, and at the same time, the external rotation rod 6 and the internal rotation rod 7 are moved closer to the direction of the uterine fibroids during the rotation, so that the first rotating piece 24 is first rotated into the fibroids.

[0056] The hook piece 25 is forced to retract into the retracting groove 26. When the uterine fibroid passes through the first rotating piece 24 and is inserted into the external rotating rod 6, the external rotating rod 6 cooperates with the rotation of the second rotating piece 27 to make the fibroid quickly rotate onto the external rotating rod 6. When the fibroid completely passes through the first rotating piece 24, the retracting groove 26 is opened by the restorative elastic force, and the barbed second rotating piece 27 limits and fixes the uterine fibroid. Then the pull strip 8 is pushed, and the first limiting ring 16 and the second limiting ring 17 guide the pull strip 8. Then the pull strip 8 is pushed to the first limiting block 22 and the second limiting block 23 to fit to stop pushing the pull strip 8. Then the pull strip 8 is rotated to make the first end 10 move toward the second end 11, so that the first end 10 is quickly connected to the second end 11 along the guidance of the guide part 12, and then the pull strip 8 is pulled, and then the second end 11 drives the first end 10 to move downward, so that the bottom of the main frame 5 moves inward. The bag 4 is then tightened to tighten the opening of the bag 4, and then the opening of the bag 4 is pulled to make the hook piece 25 hook the bag 4, and then the inner rotating rod 7 is rotated to make the inner rotating rod 7 drive the hook piece 25 to rotate, so that the hook piece 25 performs the first step of rotary sealing on the opening of the bag 4, and then the pull strip 8 continues to pull the main frame 5 to make the concave portion 28 and the convex portion 29 close to each other, so that the third weakened portion 30 is deformed, and the opening of the bag 4 is further squeezed and sealed by the extrusion of the concave portion 28 and the convex portion 29, and at the same time, the bent portion 9 is squeezed and deformed to be set in the limiting groove 19, so that the pull strip 8 and the main frame 5 are fixed to the bottom of the outer rotating rod 6, and at the same time, the second end portion 11 and the first end portion 10 are retracted into the receiving groove 18, and then the rotary cutter performs rotary cutting in the cavity of the bag 4. The structure of the device is simple and it is convenient and quick to use.
