Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a surgical vaginal manipulation aid. Background Technology

[0002] Vaginal speculum is a commonly used auxiliary tool during laparoscopic surgery. Before the procedure, lubricant should be evenly applied to the surface of the speculum to reduce discomfort during insertion. Then, the speculum should be gently and slowly pushed into the vagina until it is fully inserted. Once properly positioned, necessary examinations can be performed using a flashlight or other specialized equipment. Most commercially available vaginal speculum use a duckbill clip design. While this shape is common, it still requires manual fixation to maintain its position during actual surgery. Furthermore, when the surgery involves the removal of tissues such as the uterus, these tissues need to be removed through the vagina, and traditional duckbill clip speculum can easily interfere with the surgical procedure.

Detailed Implementation

[0041] The following is combined Figure 1-15 This utility model will be described in detail.

[0042] A surgical vaginal manipulation aid, such as Figures 1 to 15 As shown, the device includes an auxiliary body and a fixing device 30. The auxiliary body includes several first airbags 10, each with a first air port. The auxiliary body also includes several arc-shaped blocks 20, which are alternately connected to the first airbags 10 to form a closed loop, creating a first surgical channel inside. The arc-shaped blocks 20 and the first airbags 10 support the vagina, providing space for surgery while preventing accidental cutting of the vagina during the procedure. A connecting channel 201 is also provided within the arc-shaped blocks 20. The fixing device 30 includes several fixing claws 301, one end of which is pivotally connected to the opening of the connecting channel 201 and is connected to an operating rod 302. The operating rod 302 movably passes through the connecting channel 201, with its end away from the fixing claws 301 protruding from the connecting channel 201. Before entering the vagina, the auxiliary device is in its first state, as shown... Figure 1As shown, at this time, each of the first airbags 10 is in a deflated state, the opening diameter of the first surgical channel is small, and each fixing claw 301 is constricted at the upper end of the auxiliary device body, allowing the entire auxiliary device body to smoothly enter the vagina. After entering the vagina, the airbags are inflated through the first air inlet, increasing the diameter of the auxiliary device body and compressing and expanding the vaginal wall, thus expanding the vaginal wall to the appropriate surgical size, ensuring that the correspondingly enlarged first surgical channel can accommodate subsequent surgery and the removal of excised tissue after surgery. After adjusting to the appropriate size, the operating lever 302 is pulled to rotate the fixing claws 301 to abut against the vaginal wall. At this time, the auxiliary device is in the second state, as shown. Figure 2 As shown, the fixing claw 301 opens outward in an umbrella shape and is fixed within the pelvic cavity, securing the auxiliary device body inside the vagina and maintaining the vagina in an expanded state. The entire auxiliary device will not automatically squeeze out of the vagina or deform, facilitating surgical operation. In some embodiments, only some arc-shaped blocks 20 are provided with connecting channels 201. The arc-shaped blocks 20 with connecting channels 201 are evenly distributed in an array relative to the axis of the first surgical channel. Each connecting channel 201 corresponds one-to-one with each fixing claw 301. The fixing device 30 includes at least three fixing claws 301, that is, at least three arc-shaped blocks 20 are provided with connecting channels 201. The end of the arc-shaped block 20 near the pelvic cavity is rounded to form a smooth surface, preventing puncture of the vagina. The fixing claw 301 is a smooth arc-shaped strip structure. In the second state, its end face will not puncture the vagina, and the fixing claw 301 is positioned towards the arc-shaped block 20. In the first state, both ends of the fixing claw 301 are in contact with the arc-shaped block 20, and its arc-shaped surface facilitates the entry of the auxiliary device body into the vagina.

[0043] This embodiment also includes a handle. For example... Figure 15As shown, the handle includes several control blocks 40, each corresponding to a curved block 20. The top of each control block 40 has a groove 401 that fits the curved block 20. One end of the operating rod 302, exposed in the connecting channel 201, is fixedly connected to the bottom of the groove 401. Pulling the corresponding control block 40 moves the operating rod 302, allowing some of the curved blocks 20 to move along the operating rod 302 within the groove 401. The operating rod 302 and the groove 401 can be fixed by a threaded connection. Furthermore, the inner wall of the groove 401 has a first wave groove 4011, and the curved block 20 has a second wave groove 202 that slides within the first wave groove 4011, allowing the curved block 20 to move along the first wave groove 4011 and be fixed within the groove 401. After the auxiliary device body enters the vagina, the control block 40 is pulled outward, causing the operating rod 302 to move away from the pivot of the fixing claw 301, thereby driving the corresponding fixing claw 301 to rotate. The fixing claw 301 is fixed in the pelvic cavity in an umbrella shape. With the cooperation of the second wave groove 202 and the first wave groove 4011, after the control block 40 is stopped being pulled, the arc-shaped block 20 will be fixed in the groove 401 and will not move under the pressure of the vaginal wall until the operation is completed. Then, the auxiliary device body is pushed inward, so that the fixing claw 301 is no longer stuck in the pelvic cavity. Then, the control block 40 is pushed to control the fixing claw 301 to be constricted to the outer periphery of the arc-shaped block 20. Then, the gas in the first airbag 10 is released, and the auxiliary device changes from the second state to the first state, so that the auxiliary device body can be withdrawn from the vagina.

[0044] In this embodiment, the handle also includes a connector 50. A connector 50 connects adjacent control blocks 40, and the connector 50 includes at least two sets of crossbars 501. The ends of adjacent crossbars 501 are rotatably connected. Each control block 40 and each connector 50 are alternately connected to form a closed loop, creating a second surgical channel inside. In the first state, the first airbag 10 is deflated, the space of the first surgical channel is small, and each set of crossbars 501 contracts. The distance between adjacent control blocks 40 corresponds to the size of the first airbag 10. Upon entering the second state, the first airbag 10 inflates, causing the first surgical channel to expand. Correspondingly, the crossbars 501 stretch, and each control block 40 always corresponds to the arc-shaped block 20, causing the second surgical channel to expand accordingly.

[0045] In this embodiment, a second airbag 60 is also included. Each first air port is located at the bottom of the first airbag 10 and extends with an airbag tube 101. Each airbag tube 101 is connected to the second airbag 60. The second airbag 60 has a second air port, through which gas can be inflated or deflated. The second airbag 60 is annular and located within the second surgical channel, its outer periphery abutting against the inner side of each control block 40. A slot 402 is also provided on the side of the control block 40 near the second surgical channel, and the second airbag 60 is engaged within the slot 402. The slot 402 can accommodate the second airbag 60 after inflation in the second state. The contraction and expansion changes of the first airbag 10, the second airbag 60, and the connecting member 50 correspond one-to-one. During the transition between the first and second states, the operating lever 302 will not twist. In some embodiments, the side of the first airbag 10 closest to the first surgical channel is made of non-elastic fabric, while the side furthest from the first surgical channel is made of elastic material. After inflation, the side of the first airbag 10 furthest from the first surgical channel stretches and deforms, dilating the vagina. The second airbag 60 and the airbag tube 101 are made of non-elastic fabric.

[0046] In this embodiment, the arc-shaped block 20 has a movable cavity 203 at the opening of the end away from the handle. The movable cavity 203 is connected to the connecting channel 201, and the fixed claw 301 is pivotally connected to the movable cavity 203. The fixed claw 301 includes a claw portion 3012, and a transmission portion 3011 extends from the claw portion 3012 toward the movable cavity 203. One end of the transmission portion 3011 away from the claw portion 3012 is pivotally connected to a transmission rod 303, and the other end is pivotally connected to the movable cavity 203. When the control block 40 is pulled, the operating rod 302 moves along the connecting channel 201 in a direction away from the fixed claw 301. The transmission rod 303 is displaced by force in the movable cavity 203, which drives the transmission portion 3011 to rotate from the horizontal direction to the vertical direction. In some embodiments, the rotation center of the fixing claw 301 is collinear with the axis of the connecting channel 201, so that the fixing claw 301 can rotate and be fixed within a range of 90 degrees, that is, the fixing claw 301 can rotate from the axial direction of the first surgical channel to the radial direction of the first surgical channel.

[0047] In this embodiment, a first lighting device 70 is provided at one end of the arc-shaped block 20, and a second lighting device 80 is provided at the other end. The first lighting device 70 and the second lighting device 80 are located on the inner wall of the arc-shaped block 20 near the first surgical channel. A switch device 90 is provided on the handle to control the operation of the first lighting device 70 and the second lighting device 80, and the switch device 90 is electrically connected to the first lighting device 70 and the second lighting device 80. The first lighting device 70 and the second lighting device 80 can help doctors better observe the surgical area, ensuring the accuracy of the surgery and reducing the risk of complications. In some embodiments, the switch device 90 can be set independently of the auxiliary device, or it can be communicatively connected to the first lighting device 70 and the second lighting device 80. The device that supplies power to the first lighting device 70 and the second lighting device 80 is fixed on the control block 40 (not shown in the figure).

[0048] In this embodiment, the auxiliary device is used in other scenarios requiring vaginal dilation, such as medication administration. The pleated cervical drug delivery device enters the vagina through the first surgical channel, delivering the medication to the lesion site. With the assistance of the auxiliary device, the pleated cervical drug delivery device can directly visualize the lesion site for medication administration, resulting in good efficacy. It is inserted during medication administration and can be withdrawn during surgery. In some embodiments, each arc-shaped block 20 and the operating rod 302 are retractable, allowing the auxiliary device body to have the same vertical extension and retraction function as a irrigator, which can be adjusted appropriately according to the length of the vagina. Before use, the auxiliary device body is adjusted to a suitable length and then pushed into the vagina. Specifically, the arc-shaped block 20 and the operating rod 302 can be adjusted and fixed in length using spring clips or sliding grooves, similar to the ribs of an umbrella.

[0049] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
