Description

Technical Field

[0001] The invention relates to the technical field of sacrospinous ligament suspension, in particular to an opener which is beneficial to the sacrospinous ligament suspension. Background Art

[0002] Sacrospinous ligament suspension is a surgery for pelvic organ prolapse. The purpose of sacrospinous ligament suspension is to achieve the reconstruction and support of the mid-pelvic tissue, correct the defects of the mid-pelvic tissue, and ultimately improve the patient's quality of life. During the sacrospinous ligament suspension surgery, an opener is needed. When the opener is working, it can complete the intraoperative exposure at one time, simplify the opening procedure, thus shortening the operation time and improving work efficiency. It also fully exposes the surgical field of view and facilitates the operation of the staff. When using the mouth opener, after the required position is opened, if the staff keeps holding it to fix the size, it will affect the staff's subsequent operations, increase the staff's work difficulty, and affect the surgical process; In order to overcome the above defects, prior art 1 (application number: CN202221545440.1, Chinese patent application date 2022-06-20) is a multifunctional mouth opener, which saves space by fixing the straw on the inner circumferential surface of the mouth opener, and can continuously clean the patient's mouth during the operation to ensure the smooth progress of the operation. In particular, a tongue depressor assembly is added, the tongue depressor is fixed on the mouth opener, and the fixed angle of the tongue depressor and the length of the tongue depressor extending out of the patient's mouth can be adjusted at will, which improves the stability of the tongue depressor pressing against the patient's tongue; There is also prior art 2 (application number: CN200720020570.2, Chinese patent application date: 2007-04-13) a cleft palate surgery mouth opener, which has a reasonable design, simple structure, and small extraoral volume; the angle of the tongue depressor can be conveniently adjusted by bolts, and its telescopic design can make the mouth opener suitable for all kinds of patients; the mouth opener is very convenient to adjust and fix through the forceps handle, easy to operate, the mouth opening degree is firmly fixed during the operation, and the mouth opener is easy to remove after the operation; And prior art 3 (Chinese patent with application number CN202420152707.3 and application date 2024-01-22) is an adjustable dilator for oral and maxillofacial surgery. When performing oral surgery on a patient, different expanders can be selected according to different conditions inside the patient's oral cavity, and the expanders can be connected to the first handpiece and the second handpiece. Then, the expander can be extended into the patient's oral cavity, and the doctor can hold the first handpiece and the second handpiece to expand the patient's oral cavity. At this time, the relative position and angle between the first handpiece and the second handpiece can be fixed by a supporting mechanism, and after the fixation is completed, the relative position of the supporting mechanism can be fixed by a limiting mechanism, so that the angle between the first handpiece and the second handpiece cannot be changed at this time, thereby freeing the doctor's hands and facilitating the doctor to perform surgery; After the mouth opener is used, the patient's body fluids will remain on the device, and the device needs to be centrally disinfected after use. The device in the above application does not have a pre-disinfection structure when in use, and there is a risk of cross infection after the device is centrally disinfected, which is less safe. At the same time, the support plate of the mouth opener will wear and deform after long-term use. The device in the above application has an integrated structure of the support plate and the handle, and does not have a structure for replacing the support plate separately, which will affect the subsequent use of the entire device and bring unnecessary troubles to the surgical process.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the mouth opener for sacrospinous ligament suspension adopts a novel structural design, and the angles of the first handle and the second handle can be fixed by the provided locking assembly, thereby facilitating the operation of the staff and improving the work efficiency. Meanwhile, the provided disinfection assembly can make the nozzle spray disinfectant in the direction of the opening plate, thereby improving the safety. Moreover, a disassembly assembly assembly is provided, so that the opening plate can be quickly replaced, thereby ensuring the normal operation of the entire device. The specific contents are as follows: (1) When the opening device for sacrospinous ligament suspension surgery is used, when the opening plate needs to be opened, the two adjacent opening plates can be rotated by the first handle and the second handle, thereby opening the opening plates. During the opening process, the positioning bar slides inside the second handle, and the first handle and the second handle are engaged through the positioning bar, the positioning hole and the vertical rod. At this time, the angles of the first handle and the second handle are fixed, thereby facilitating the operation of the staff and improving the work efficiency.

When the opening plate is opened, the pressure plate moves away from the airbag. At this time, the airbag absorbs the disinfectant in the material box into the airbag through the lower pipe. When the opening plate returns to its original position, the pressure plate also returns to its original position. At this time, the airbag is squeezed, and then the airbag sprays the disinfectant through the feeding pipe and the nozzle, thereby improving the overall safety of the device. Furthermore, the first one-way valve and the second one-way valve make the disinfectant flow from the material box to the nozzle, and no backflow occurs, thus ensuring stability; (3) When the opening device for sacrospinal ligament suspension surgery needs to be replaced with a new opening plate after long-term use, the push block can be pulled, and the push block drives the end of the card block to move out of the card slot, and then the opening plate can be directly pulled out. When installing a new opening plate, the opening plate can be inserted into the surface of the auxiliary block. When the end of the card block and the card slot are in the same horizontal direction, the card block will enter the inside of the card slot under the action of the push block and the reset spring. At this time, the replacement of the opening plate has been completed, ensuring the normal use of the entire device. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Embodiment 1: By setting the locking assembly, the first handle 1 and the second handle 2 can be quickly fixed at an angle, which is convenient for the operator to operate. Figure 1-Figure 4 As shown: It comprises a handle number 1 and a handle number 2, wherein an upper connecting block 3 is fixedly connected to the side of the handle number 1, and a lower connecting block 4 is fixedly connected to the side of the handle number 2. A connecting shaft 5 is rotatably arranged inside the lower connecting block 4, and the upper surface of the connecting shaft 5 is fixedly connected to the lower surface of the upper connecting block 3; The ends of the first handle 1 and the second handle 2 are both fixedly connected with auxiliary blocks 6, and the ends of the auxiliary blocks 6 are snap-connected with the opening plate 12, and a locking assembly is provided between the first handle 1 and the second handle 2, and the locking assembly includes a positioning strip 7 fixedly connected to the inner wall of the first handle 1; A disinfection assembly is provided between the first handle 1 and the second handle 2, and the disinfection assembly includes a placement plate 14 bolted to the inner wall of the first handle 1, and when the disinfection assembly is working, the disinfectant is sprayed in the direction of the opening plate 12; A disassembly and assembly component is arranged between the auxiliary block 6 and the opening plate 12, and the disassembly and assembly component includes a clamping block 23 movably arranged inside the opening plate 12, and the locking assembly also includes a vertical rod 9 movably connected to the inside of the No. 2 handle 2, and the vertical rod 9 runs through the inside of the No. 2 handle 2, and the upper surface of the vertical rod 9 is fixedly connected to the connecting plate 10, and the surface of the vertical rod 9 is inclined.

[0019] The upper surface of the positioning bar 7 is provided with a positioning hole 8 corresponding to the vertical rod 9, and the positioning bar 7 is an arc-shaped structure, and the center of the positioning bar 7 and the center of the connecting shaft 5 are at one point, and the positioning holes 8 are distributed at equal angles on the upper surface of the positioning bar 7, and the lower surface of the connecting plate 10 is fixedly connected to a connecting spring 11 that plays an elastic reset role, and the other side of the connecting spring 11 is fixedly connected to the upper surface of the No. 2 handle 2, and the surface of the connecting shaft 5 is fixedly connected to a torsion spring 27 that plays an elastic reset role, and the other side of the torsion spring 27 is fixedly connected to the inner wall of the lower connecting block 4.

[0020] When in use, when it is necessary to open the opening plate 12, the two adjacent opening plates 12 can be rotated by the No. 1 handle 1 and the No. 2 handle 2, thereby opening the opening plate 12. During the opening process, the positioning bar 7 will slide inside the No. 2 handle 2. At this time, the positioning bar 7 will push the vertical rod 9 to move upward through the outer surface. When the vertical rod 9 moves, the connecting spring 11 will be stretched through the connecting plate 10. When the lower surface of the vertical rod 9 and the corresponding positioning hole 8 are in the same vertical direction, the vertical rod 9 enters the corresponding positioning hole 8 under the action of the connecting plate 10 and the connecting spring 11. At this time, the No. 1 handle 1 and the No. 2 handle 2 are locked. During the rotation process of the No. 1 handle 1 and the No. 2 handle 2, the upper connecting block 3 will drive the connecting shaft 5 to rotate inside the lower connecting block 4. At this time, the torsion spring 27 is stretched, that is, when the No. 1 handle 1 and the No. 2 handle 2 are locked, the torsion spring 27 always has a tendency to return the No. 1 handle 1 and the No. 2 handle 2, so that the opening plate 12 will not continue to open, and the stability is strong.

[0021] Embodiment 2: Different from Embodiment 1, the disinfection assembly is provided so that the nozzle 21 can spray disinfectant, thereby improving safety. Figure 5-Figure 7 As shown: The disinfection assembly also includes a pressure plate 13 bolted to the inner wall of the second handle 2, and the pressure plate 13 and the placement plate 14 are both inverted "L" structures when viewed from above, and the airbag 15 is bonded to the surface of the placement plate 14, and the pressure plate 13 is initially in a state of squeezing the airbag 15.

[0022] A material box 16 is fixedly connected to the outer wall of the placement plate 14, a feeding pipe 17 is fixedly connected to the surface of the airbag 15, and a nozzle 21 is fixedly connected to the end of the feeding pipe 17, and a first one-way valve 18 is fixedly connected to the surface of the feeding pipe 17, a lower connecting pipe 19 is fixedly connected to the lower end surface of the airbag 15, and a second one-way valve 20 is fixedly connected to the surface of the lower connecting pipe 19, and the end of the lower connecting pipe 19 is arranged inside the material box 16.

[0023] Initially, the pressing plate 13 is in a state of squeezing the airbag 15, and when the opening plate 12 is opened, the pressing plate 13 will move away from the airbag 15. At this time, the airbag 15 expands, and then the airbag 15 sucks the disinfectant inside the material box 16 into the airbag 15 through the lower connecting pipe 19. When the opening plate 12 returns to its original position, the pressing plate 13 will also return to its original position. At this time, the airbag 15 is squeezed, and then the airbag 15 sprays the disinfectant through the feeding pipe 17 and the nozzle 21, thereby improving the overall safety of the device. The first one-way valve 18 and the second one-way valve 20 make the flow direction of the disinfectant from the material box 16 to the nozzle 21 (the material box 16 can be connected to the box cover), and backflow will not occur, thereby ensuring stability.

[0024] Embodiment 3: Different from Embodiment 2, the opening plate 12 can be quickly replaced by means of the disassembly and assembly components. Figure 8-Figure 11 As shown: The disassembly and assembly component also includes a docking groove 22 opened on the surface of the opening plate 12, the end of the card block 23 is located on the outside of the opening plate 12, and the end of the card block 23 is fixedly connected to a shift block 24, the surface of the auxiliary block 6 is provided with a card groove 26 corresponding to the card block 23, and the surface of the card block 23 is inclined, and the surface of the shift block 24 is fixedly connected to a reset spring 25 that plays an elastic reset role, and the other side of the reset spring 25 is fixedly connected to the outer wall of the opening plate 12.

[0025] After long-term use, when a new opening plate 12 needs to be replaced, the shift block 24 can be pulled. At this time, the shift block 24 drives the end of the card block 23 to move out of the card slot 26, and then the opening plate 12 at this time can be directly pulled out. When installing a new opening plate 12, the opening plate 12 can be inserted into the surface of the auxiliary block 6, so that the auxiliary block 6 enters the interior of the docking groove 22. When the end of the card block 23 and the card slot 26 are in the same horizontal direction, the card block 23 will enter the interior of the card slot 26 under the action of the shift block 24 and the reset spring 25. At this time, the replacement of the opening plate 12 has been completed, ensuring the normal use of the entire device.

[0026] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
