Description

Technical Field

[0001] The present invention belongs to the field of medical devices, and specifically relates to a visual pelvic floor puncture device and its auxiliary equipment. Background Art

[0002] Female pelvic floor dysfunction diseases are common diseases among middle-aged and elderly women, seriously affecting the quality of life of patients. At present, research on such diseases has formed a new discipline, namely gynecological urology and female pelvic floor reconstruction surgery. At this stage, there are more than 100 surgical methods based on the basic theory of the pelvic floor. Among them, vaginal pelvic floor reconstruction is an important and irreplaceable type of pelvic floor surgery at present, providing treatment opportunities for elderly patients with complications. However, the blind puncture technique in vaginal pelvic floor reconstruction surgery is the key difficulty restricting its technological development.

[0003] To solve the above blind puncture problem, the utility model solution with the prior art publication number CN208481425U discloses a pelvic floor surgery puncture device and a puncture device combination kit. This technical solution mainly has a handle and a puncture head respectively provided at both ends of the rod portion. The first front section or the second front section of the rod portion and the puncture head are integrally arc-shaped, and a hook-shaped notch is provided on the outer arc surface of the rod portion near the puncture head. When performing blind puncture, a suture is hooked on the hook-shaped notch from the outside of the rod portion. The purpose of such a design is to be able to completely hang the guiding silk thread onto the notch of the puncture device by the blind probing method.

[0004] Although the above prior art hangs the guiding silk thread (essentially a suture) onto the notch of the puncture device by the blind probing method, the guiding silk thread will then be taken out of the body together when the puncture device exits the needle, avoiding the displacement of the puncture point of the obturator internus muscle. However, this technique is only effective when taking out the puncture device. During the puncture process, medical staff still need to judge the puncture position according to experience, and the essence of blind puncture has not changed. Summary of the Invention

[0005] To solve the above problems, the purpose of the present invention is to construct a visual pelvic floor puncture auxiliary device, which is convenient for medical staff to perform imaging observation on the pelvic floor of patients during surgery, determine the puncture position, and overcome the surgical risks of blind puncture.

[0006] To achieve the above purpose, the technical solution of the present invention is as follows: A visual pelvic floor puncture auxiliary device includes a cylindrical sleeve for supporting the gap and a visual operation kit for observing the pelvic floor. The inside of the sleeve is equally divided into several hollow grids, the grids are spaced at equal distances, and a sheath for loading the visual operation kit passes through between the grids. The visual operation kit includes an endoscope inside the sheath and a display screen for displaying the image of the endoscope.

[0007] A visual pelvic floor puncture device includes a handle for holding and a drainage tube for flushing. The drainage tube is inserted into the handle;

[0008] The drainage tube includes a water inlet end and a water outlet end. A set of connectors is provided between the water inlet end and the water outlet end. A through valve is sleeved on the water outlet end. The inlet of the water inlet end is communicated with a four-way pipe. The ports of the four-way pipe are communicated with a puncture tube, a pressure outlet tube and a pressure receiving tube. The last port of the four-way pipe is communicated with the water inlet end of the drainage tube. The puncture tube, the pressure outlet tube and the pressure receiving tube are located on the same side;

[0009] The cross-section of the handle is "7"-shaped. The handle includes a horizontal connecting portion and a vertical control portion. The connecting portion is communicated with the puncture tube. The connecting portion and the control portion are integrally manufactured. The control portion is provided with a pressure outlet hole and a circulation hole from top to bottom. The pressure outlet tube passes through the pressure outlet hole. The part of the pressure outlet tube exceeding the pressure outlet hole is communicated with a perfusion pump. The pressure receiving tube passes through the circulation hole. A control member for blocking the pressure receiving tube is provided at the connection between the circulation hole and the pressure receiving tube. A shunt tube is connected to the connection between the pressure receiving tube and the control member.

[0010] After adopting the above scheme, the following beneficial effects are achieved: 1. Compared with the traditional pelvic floor puncture device, a cylindrical sleeve is constructed in this technical solution, which is applicable to surgeries such as vaginal septum, congenital absence of vagina, vaginal atresia, vaginal tumors, etc. It performs internal vaginal drainage and support after surgery, reduces the risk of adhesion formation and infection during the incision healing process, and improves the surgical effect.

[0011] 2. Compared with the visual puncture surgical device, grid interval layering is adopted in this technical solution to provide a distance reference object, which is convenient for medical staff to estimate the distance through the grid and grasp the position during puncture.

[0012] 3. Compared with the drainage tube with a single-way pipeline, multi-pass pipeline drainage is adopted in this technical solution to construct a circulation channel, which improves the effect of flushing the internal vagina.

[0013] 4. Compared with the existing technology of constructing a circulation system, the handle with specific settings in this technical solution is convenient for medical staff to hold and connect the pipelines, improving the convenience of use.

[0014] 5. Compared with the traditional TVM surgical process, it changes from blind puncture to visual puncture, making the puncture site more accurate, the surgical effect more definite, and greatly reducing the risk of damage to blood vessels, nerves and surrounding important organ tissues caused by blind puncture.

[0015] 6. Compared with the puncture device for establishing a formed image, this device in this technical solution has an integrated design, is easy to operate, does not require carbon dioxide to establish a pneumoperitoneum, has a low cost, and can be disinfected and reused.

[0016] 7. Compared with the existing technology without pneumoperitoneum, the cylindrical transparent sleeve constructed in the present technical solution has different thicknesses according to the individual design of the patient. After the visual operation kit connected to the base is disassembled, it can be further used for vaginal drainage and support after vaginal surgeries such as vaginal septum, congenital absence of vagina, vaginal atresia, vaginal tumors, etc., to reduce the risk of infection and adhesion during incision healing and improve the surgical effect.

[0017] Furthermore, the endoscope includes a lens and a bracket hinged on both sides of the lens, and the rear end of the lens is provided with an operating module for controlling the swing of the lens.

[0018] Beneficial effect: It is convenient to swing the lens and switch the viewing angle.

[0019] Furthermore, the operation module and the signal are connected to a control module for converting electrical signals and analog signals. The control module is built into a display screen, and the display screen is connected to an input device for driving the control module to swing.

[0020] Beneficial effects: Human-computer interactive operation is realized, and the visual range of the endoscope is adjusted by inputting commands through the control terminal, thereby enhancing the field of view adjustment performance.

[0021] Furthermore, the control element includes a button and a through valve, wherein the button is provided with a push rod, a slot and a tension spring in sequence from the inside to the outside, and the through valve is provided with a start switch;

[0022] The tail end of the push rod is fixedly connected with a disc, and a touch rod is engaged inside the disc. The touch rod contacts the start switch of the valve during its movement. A radial ear is provided at the tail end of the touch rod. The ear contacts the tension spring, and a limit block is provided between the ear and the disc to limit the sliding of the ear. The number of the limit blocks is 2, and the limit blocks are located on both sides of the radial direction of the button. The limit blocks form an angle of 180° with each other. The circumference of the disc is processed with vertical edges, which are slidably connected with the card slot, and the top of the vertical edge is processed with helical teeth.

[0023] The tail end of the slot is processed with an inclined surface, and a reverse self-locking angle is formed between the inclined surface and the helical teeth.

[0024] Beneficial effects: 1. Compared with the existing technology of continuous pressing for control, this technical solution only needs one press when in use. Since an anti-self-locking angle is generated between the disc and the slot, the disc rotates after being subjected to force, and the rotating disc drives the touch rod to rotate. When the disc and the slot are offset, the support ear of the touch rod engages with the limit block. At this time, the touch rod always remains in the ejected state, and the ejected length is the length of the slot.

[0025] 2. Compared with the prior art that always maintains ejection, when this technical solution is used, the disc is rotated by pressing again. When the vertical edge of the disc aligns with the card slot, the vertical edge drives the disc to sink into the card slot, and the locking state is released at this time, avoiding continuous pressing force and reducing the fatigue degree of medical staff during operation.

[0026] Further, a puncture needle is provided in the puncture tube, and the tail end of the puncture needle is connected to an adjusting device for telescoping the puncture needle. The adjusting device is located at the connecting part of the handle.

[0027] Beneficial effects: It is convenient for medical staff to perform puncture, avoiding external puncture and saving operation time.

[0028] Further, the adjusting device includes a lifting platform, an adjusting rack, a rotating gear, a base and a screw rod that are sequentially connected along the direction from the inner vagina to the connecting part. Grooves are opened on both radial sides of the base, and the adjusting racks placed vertically are in clearance fit in the grooves. The adjusting racks are engaged with the rotating gear, and the rotating gear is horizontally placed. The rotating gear includes a driving wheel and a driven wheel that are engaged with each other. The driving gear is engaged with the screw rod, and the driving wheel and the driven wheel are respectively engaged with an adjusting rack. One end of the adjusting rack is fixedly connected to the lifting platform, and the other end of the adjusting rack sinks into the groove of the base.

[0029] Beneficial effects: 1. Compared with the prior art with the publication number of CN108721708A, when this technical solution is implemented, medical staff can rotate the screw rod to drive the rotating gear and the rack in sequence to extend the working range of the drainage tube, improving the practicability.

[0030] 2. Compared with the prior art with single-rack adjustment, the double-rack adjustment in this technical solution improves the support for the base, solves the dynamic balance problem generated after the lifting distance of the rack is extended, avoids the unidirectional force on the rack, and improves the service life of the rack.

[0031] 3. Compared with the prior art using screw rod adjustment, this technical solution uses gear adjustment to achieve bidirectional sliding, enhancing the usability and fault tolerance of the device.

[0032] Further, a dovetail groove is opened at the vertical central axis of the base, and the puncture needle is slidably connected in the dovetail groove. An adjusting table is in clearance fit with the dovetail groove. The adjusting table protrudes from the surface of the base, and the adjusting table is in clearance fit with the dovetail groove.

[0033] Beneficial effects: 1. Compared with the prior art using the drainage tube for direct puncture, this technical solution uses the puncture needle for easy puncture, avoiding the influence of the thickness of the inner vagina epidermis on the operation.

[0034] 2. Compared with the existing technology using a puncture needle, this technical solution adds an adjustment table to adjust the depth of the puncture needle inserted into the inner vagina, avoiding damage to the blood vessels in the inner vagina by the puncture needle and reducing the risk of the puncture needle breaking and remaining in the patient's body during drainage.

[0035] Further, an empty window is opened on the surface of the base. A horizontally placed screw rod is rotatably connected inside the empty window, and a precision bolt for connecting the base and the screw rod axially penetrates through the screw rod.

[0036] Beneficial effect: It is convenient for medical staff to slide and adjust.

[0037] Further, a gear lock is provided at the meshing position of the driven gear and the driving gear. The gear lock is rotatably connected with a lock wrench. The lock wrench is located on the outer surface of the base, and a coaxial pin is connected between the lock wrench and the gear lock. A triangular mark is provided on the surface of the base, and the direction pointed by the triangular mark is consistent with the rotation direction of the screw rod when the adjustment rack is lifted.

[0038] Beneficial effect: Medical staff can pull the wrench to drive the lock to lock, improving stability. An anti-fooling design is carried out to prevent the rack from breaking when medical staff slides unidirectionally. Description of the Drawings

[0051] The difference between this embodiment and the above embodiment is that a visual pelvic floor puncture device is added, which is basically as shown in the attached Figure 2 : A visual pelvic floor puncture device includes a handle 18 for holding and a drainage tube 1 for flushing. The drainage tube 1 is inserted into the handle 18;

[0052] The drainage tube 1 includes a water inlet end and a water outlet end, a group of joints 11 are bonded between the water inlet end and the water outlet end, a through valve 20 is sleeved on the water outlet end, the inlet of the water inlet end is connected to a four-way pipe 2, and the port of the four-way pipe 2 is connected to a puncture tube 3, a pressure outlet pipe 4 and a pressure receiving pipe 5.

[0053] Please refer to Figure 3 A puncture needle 13 is placed in the puncture tube 3, and the tail end of the puncture needle 13 is connected to an adjusting device 7 for retracting the puncture needle 13. The adjusting device 7 is located at the connection part of the handle 18. The adjusting device 7 includes a lifting platform 8, an adjusting rack 9, a rotating gear 10, a base and a screw 12 which are sequentially connected along the direction from the inner vagina to the connection part. Grooves are opened on both radial sides of the base, and the grooves are gap-fitted with vertically placed adjusting racks 9. The adjusting rack 9 is meshed with the rotating gear 10, and the rotating gear 10 is water-tight. Placed horizontally, the rotating gear 10 includes a driving wheel 101 and a driven wheel 102 meshing with each other, the driving gear meshes with the screw 12, the driving wheel 101 and the driven wheel 102 respectively mesh with an adjusting rack 9, one end of the adjusting rack 9 is fixedly connected to the lifting platform 8, the meshing point of the driven gear and the driving gear is hinged with a gear lock 15, the gear lock 15 is rotatably connected with a locking wrench 16, the locking wrench 16 is located on the outer surface of the base, and a coaxial pin is connected between the locking wrench 16 and the gear lock 15. The other end of the adjusting rack 9 is immersed in the groove of the base.

[0054] A dovetail groove is provided at the vertical center axis of the base, and a puncture needle 13 is slidably connected in the dovetail groove. An adjustment platform 14 is provided in the gap of the dovetail groove. The adjustment platform 14 protrudes from the surface of the base, and the adjustment platform 14 is matched with the gap in the dovetail groove. A hollow window is provided on the surface of the base, and a horizontally placed screw rod 12 is rotatably connected in the hollow window. A hinged bolt for connecting the base and the screw rod 12 passes through the axial direction of the screw rod 12. A triangular mark 17 is processed on the surface of the base, and the direction of the triangular mark is consistent with the rotation direction of the screw rod 12 when the adjustment rack 9 is lifted.

[0055] The cross section of the handle 18 is in the shape of a "7". The handle 18 includes a horizontal connecting portion and a vertical control portion. The connecting portion is connected to the puncture tube 3, and the connecting portion and the control portion are manufactured as one piece. The control portion has a pressure outlet hole and a circulation hole from top to bottom. The pressure outlet tube 4 passes through the pressure outlet hole, and the portion of the pressure outlet tube 4 that exceeds the pressure outlet hole is connected to an infusion pump. The pressure receiving tube 5 passes through the circulation hole, and the connection between the circulation hole and the pressure receiving tube 5 blocks the control component of the pressure receiving tube 5. The connection between the pressure receiving tube 5 and the control component is connected to a shunt tube, which extends out from the bottom of the control portion, and is connected to a collection bag 29.

[0056] Please refer to Figure 4The control member includes a button 19 and a valve 20. The button 19 is provided with a push rod 21, a slot 22 and a tension spring 23 from the inside to the outside. The valve 20 is provided with a starting switch. The tail end of the push rod 21 is fixedly connected with a disc 24. A touch rod 25 is engaged inside the disc 24. The touch rod 25 contacts the starting switch of the valve 20 during its movement. The tail end of the touch rod 25 is provided with a radial ear 26. The ear 26 contacts the tension spring 23. A limit block 27 for limiting the sliding of the ear 26 is provided between the ear 26 and the disc 24. The number of the limit blocks 27 is 2. The limit blocks 27 are located on both sides of the radial direction of the button 19. The limit blocks 27 form an angle of 180° with each other. The circumference of the disc 24 is processed with vertical edges. The vertical edges are slidably connected with the slot 22. The top of the vertical edges is processed with oblique teeth 28. The tail end of the slot 22 is processed with an inclined surface, and the inclined surface and the oblique teeth 28 form a reverse self-locking angle.

[0057] The principle of the reverse self-locking angle is as follows: Assuming that the inclination angle of the bevel gear 28 is x, x should be greater than arctanf. According to the parallelogram law of mechanics, if the bevel gear 28 of the turntable is unfolded around the vertical axis, the bevel gear 28 of the turntable is an inclined plane. Assuming that the angle enclosed by the teeth of the bevel gear 28 is x, the slot 22 can be regarded as an object placed on the inclined plane. Assuming that the extrusion force on the push rod 21 is F, the friction force on the turntable is f, and N is the pressure after F is decomposed, the following calculation formula is obtained:

[0058] N = Fcosx The maximum static friction of the inclined plane is fmax = fN = fFcosx

[0059] In the direction of the inclined plane t, we can get:

[0060] Ft=fmax-Fsinx=fSFcosx-Fsinx=F(fcosx-sinx)=0

[0061] Combining and simplifying the two equations, we can obtain fcosx-sinx=0, that is, tanx=f, and the friction angle=arctanf, which is the reverse self-locking angle.

[0062] The specific implementation process is as follows: when performing puncture, the medical staff holds the adjustment device 7 of the technical solution and starts drainage.

[0063] During the drainage process, the medical staff first determines the position where the inner vulva needs to be punctured. When the puncture needle 13 needs to be extended, the medical staff rotates the screw 12 with the thumb in the direction indicated by the triangular mark 17. The screw 12 begins to rotate due to the restriction of the hinged bolt. The rotating bolt drives the active gear meshing with it to rotate. At this time, the active gear rotates and drives the driven gear meshing with the active gear to rotate in the opposite direction. The rotating active gear and the driven gear respectively drive the adjusting rack 9 meshing with themselves to move left, and the rack on the left drives the lifting platform 8 to move upward, thereby increasing the length of the drainage tube 1.

[0064] Secondly, the medical staff performs the puncture operation. During the puncture process, the medical staff pushes the adjustment table 14. When the adjustment table 14 moves to the left, the puncture needle 13 connected to the adjustment table 14 also moves to the left. When the puncture needle 13 pierces the inner vulva, the medical staff immerses the water inlet end of the drainage tube 1 into the inner vulva. At this time, the medical staff slides the adjustment table 14 to the right to prevent the puncture needle 13 from contacting the inner vulva.

[0065] During the flushing stage, the medical staff turns on the irrigation pump, and the water flows along the pressure outlet pipe 4 into the drainage tube 1 to drain and flush the inner vulva. At this time, the medical staff presses the button 19 after a certain period of water irrigation. When the button 19 moves backward, it drives the push rod 21 to slide out of the slot 22. At this time, the push rod 21 drives the touch rod 25 and the tension spring 23 to compress in turn. When the disk 24 connected to the push rod 21 is separated from the slot 22, the vertical edge on the surface of the disk 24 contacts the inclined surface. At this time, the inclined teeth 28 and the inclined surface are in a state of reverse self-locking angle. The disk 24 converts the pressure into circumferential force and then rotates. The rotating disk 24 drives the touch rod 25 to rotate. When the disk 24 is staggered with the slot 22, the ear 26 of the touch rod 25 is engaged with the limit block 27. At this time, the touch rod 25 always remains in the ejected state, and the ejected length is the length of the slot 22 and the length of the prism.

[0066] At this time, the ejected push rod 21 touches the start switch of the valve 20, and the valve 20 operates, and a circulation loop is generated in the drainage tube 1, and the blood in the vagina is mixed with the liquid medicine and collected in the collection bag 29. When the drainage is completed, the medical staff presses the button 19, and then the movement direction and mode of the disc 24 are opposite to those in the flushing stage, until the disc 24 gradually sinks into the card slot 22, and the medical staff turns off the perfusion pump to complete the flushing and drainage.

[0067] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
