Description

Technical Field

[0001] The invention relates to the technical field of puncture sheaths, in particular to a visual puncture expander. Background Art

[0002] When a surgical operation is performed to treat a disease, it is necessary to accurately puncture the lesion site or establish a surgical channel. For example, in brain tumor or cerebral hemorrhage surgery, spinal or abdominal surgery, etc., it is necessary to accurately establish a channel. These surgeries require precise puncture to reach the surgical site to ensure the success of the operation. The existing surgical channel insertion operations are non-visualized, which sometimes results in failure or serious side effects. In order to avoid surgical failure due to incorrect puncture direction,

[0003] Therefore, it is necessary to design a visual puncture expander, which can assist the operator to observe the puncture direction, position, and surrounding conditions in real time through the visualization of the puncture sheath, accurately reach the lesion, and complete the puncture, expansion, and sheath placement at one time, avoiding secondary damage caused by the secondary placement of the working sheath, thereby improving the accuracy, efficiency, and safety of the operation. Summary of the invention

[0004] The purpose of the present invention is to provide a visual puncture expander to address the deficiencies in the prior art.

[0005] A visual puncture extender comprises a support plate, a covering film, an endoscope and a support rod, wherein:

[0006] The support disk is a disk-shaped structure with a through hole in the middle, and a plurality of support rods are distributed in a circular array around the circumferential side wall of the support disk and rotate with the circumference of the support disk as an axis, and a plurality of support rods are enclosed on one side of the support disk to form a conical expansion cavity;

[0007] The coating is a non-bottomed component made of elastic latex material, which is sleeved outside the enclosed plurality of support rods and covers the outside of the conical expansion cavity;

[0008] The endoscope is placed inside the conical expansion cavity.

[0009] Furthermore, a rectangular through groove is provided on a side surface of the support plate close to the support rod at a position corresponding to each support rod, and a round pin hole is provided on the inner symmetrical side surface of each rectangular through groove.

[0010] Furthermore, it also includes a puncture airbag, which is arranged inside the support plate, and one end of the puncture airbag is inserted into the expansion cavity through the through hole on the support plate and extends to the outside through the coating;

[0011] The puncture airbag adopts one of an air pump pressurization method and a syringe pressurization method.

[0012] Further, an end of the support rod inserted into the rectangular through slot is fixedly connected to an L-shaped connecting member. A round pin is correspondingly installed at a position of the L-shaped connecting member corresponding to the round pin hole. The L-shaped connecting member rotates inside the rectangular through slot through the round pin hole and the round pin, and the support rod rotates around the round pin hole of the support disc.

[0013] Further, an included angle between two sides of the L-shaped connecting member is less than ninety degrees. The L-shaped connecting member is arranged as an inverted L shape. An end of the L-shaped connecting member perpendicular to the support rod is a short side, and an upper side wall surface of the short side is arranged as an inclined surface gradually thinning from inside to outside.

[0014] A bayonet is provided at a position of the rectangular through slot close to the outer circumferential side wall of the support disc. When the support rod rotates until the expansion cavity opens to the maximum extent, the short side of the L-shaped connecting member is snapped into the bayonet.

[0015] Further, a bracket is further included. The bracket covers an outer surface of a plurality of the support rods enclosing to form the expansion cavity. A film covering is sleeved on an outer surface of the bracket, and the endoscope is embedded inside the bracket.

[0016] Further, a fixed handle, a movable handle and a nut are further included, wherein:

[0017] A handle extends outward from one side of the support disc, and a threaded boss protrudes upward from one end surface. The support disc, the handle and the threaded boss are integrally formed to form the fixed handle.

[0018] The movable handle is a disc-shaped member with a handle and a through opening penetrating through the middle. The movable handle is sleeved on the threaded boss of the fixed handle from top to bottom and fixed by the nut.

[0019] Further, a plurality of semi-circular bosses are arranged at equal intervals in a circumferential direction on a bottom surface of the movable handle close to the fixed handle. The number of the semi-circular bosses is equal to the number of the support rods.

[0020] Further, the rectangular through slot penetrates through upper and lower side walls of the support disc. An end of the support rod inserted into the rectangular through slot is fixedly connected to a C-shaped connecting member. A round pin is correspondingly installed at a position of the C-shaped connecting member corresponding to the round pin hole. The C-shaped connecting member rotates inside the rectangular through slot through the round pin hole and the round pin, and the support rod rotates around the round pin hole of the support disc.

[0021] An upper end portion of the C-shaped connecting member perpendicular to the support rod is arranged as an inclined surface gradually thinning from inside to outside, and a lower end portion of the C-shaped connecting member is fixedly connected to the support rod.

[0022] Further, the number of the support rods is set to six, and the number of the rectangular through slots is set to six.

[0023] The advantages of the present invention compared with the prior art are as follows:

[0024] 1. Compared with the non-visual operation of inserting a surgical channel in the prior art, by means of the overall structure designed in this solution, a conical expansion cavity composed of a support rod and a disc is utilized, which facilitates the sleeving of an endoscope inside it. Thus, visualization can be achieved through the endoscope to assist the operator in observing the puncture direction, position, and surrounding conditions in real time, accurately reach the lesion, and complete the work of puncture, dilation, sheath placement, etc. at one time, avoiding secondary injuries caused by the secondary insertion of the working sheath, thereby improving the accuracy, efficiency, and safety of the operation;

[0025] 2. By setting a fixed handle, a movable handle, and a puncture airbag, compared with the puncture airbag, the rotation of the support rod can be achieved by rotating the movable handle, or the support rod can be rotated by the pressurized inflation of the puncture airbag, so that multiple support rods all rotate to form a shape of outward expansion, opening the expansion cavity to form an inverted frustum shape, facilitating the completion of work such as puncture, dilation, and sheath placement at one time, and improving the efficiency and safety of the operation.

[0037] Example 1

[0038] This embodiment provides a visual puncture expander, as shown in the attached manual Figure 1-3 As shown, it mainly includes a support plate 1, a covering film 2, a puncture balloon 3 and an endoscope 4;

[0039] Among them, the support disk 1 is a disc-shaped structure with a through hole running through the middle part, and a plurality of support rods 5 rotating around the circumference of the support disk as an axis are arranged on the circumferential side wall in a circumferential array distribution manner. In this embodiment, six support rods 5 are specifically arranged, and the following description is taken as an example. The six support rods 5 are enclosed on one side of the support disk 1 to form a conical expansion cavity, and the coating 2 of elastic latex material is sleeved on the outside of the six support rods 5 to wrap the conical expansion cavity. When the support rods 5 are contracted to a cone-like shape, it is convenient to accurately puncture the lesion site or establish a surgical channel. After puncturing to the designated site, the puncture airbag 3 is pressurized and inflated. The inflation and expansion methods include but are not limited to air pump pressurization methods and syringe pressurization methods. The expanded puncture airbag 3 drives the rotating support rod 5 to rotate outward, that is, the expansion cavity opens, thereby facilitating surgical operations;

[0040] Reference Figure 1-2 Specifically, one end of the puncture balloon 3 is inserted into the expansion cavity through the through hole on the support plate 1 and extends to the outside through the coating 2. An endoscope 4 is installed inside the puncture balloon 3. The endoscope 4 can refer to the endoscope in the prior application CN219306857U of the applicant and the endoscope in the prior application CN113425384B. This is the prior art and will not be described in detail here. In this embodiment, the puncture balloon 3 adopts an air pump pressurization method. Other methods that can pressurize the puncture balloon 3 are all possible, including but not limited to a syringe pressurization method. When the puncture balloon 3 is pressurized and expanded by the air pump, the puncture balloon 3 will expand from the middle to both sides to form a spherical structure, thereby pushing the support rod 5 to rotate and then expand the expansion cavity. The expanded support rod 5 is fixed. Therefore, when the puncture balloon 3 is decompressed and contracted, the expansion cavity will not shrink. At this time, the puncture balloon 3 is removed and the endoscope 4 is inserted to facilitate visualization through the endoscope 4, so as to facilitate accurate puncture to reach the surgical site and improve the accuracy of the operation.

[0041] Please refer to the instruction manual Figure 3 , the support rod and the rotation method in this embodiment are specifically described:

[0042] Among them, a rectangular through groove 11 is provided on one side of the support plate 1 close to the support rod 5 at the position corresponding to the six support rods 5, and a round pin hole 12 is provided on the symmetrical side of each rectangular through groove 11, and a bayonet 13 is provided at the position of the rectangular through groove 11 close to the outer side of the circumference of the support plate 1;

[0043] Moreover, the end of the support rod 5 inserted into the rectangular through groove 11 is fixedly connected to the L-shaped connecting piece 51, the support rod 5 and the L-shaped connecting piece 51 are welded into a whole, and a round pin 511 is installed correspondingly at the position of the L-shaped connecting piece 51 corresponding to the round pin hole 12, and the L-shaped connecting piece 51 rotates inside the rectangular through groove 11 through the round pin hole 12 and the round pin 511, so that the support rod 5 rotates around the round pin hole 12 of the support plate 1;

[0044] The angle between the two sides of the L-shaped connecting piece 51 is less than ninety degrees. The L-shaped connecting piece 51 is arranged to be an inverted L-shape, that is, an inverted "7" shape. The end of the L-shaped connecting piece 51 perpendicular to the support rod 5 is the short side, and the upper side wall surface at the short side is arranged to be an inclined surface that gradually becomes thinner from the inside to the outside, so as to facilitate the insertion of the short side inclined surface into the bayonet 13 after rotation.

[0045] Continue to refer to Figure 3 When the puncture airbag 3 is pressurized and expanded by the air pump, the expanded puncture airbag 3 gradually deforms and pushes the support rod 5 to move. The support rod 5 moves in the opposite direction away from the center line of the support disk 1 with the round pin hole of the support disk 1 as the center, and drives the coating 2 to expand. When the inclined surface of the short side end of the support rod 5 is stuck in the bayonet 13 of the support disk 1, it stops. At this time, the opening size of the long side end of the support rod 5 is larger than the size of the hinged position between it and the support disk 1, and it is in the shape of an inverted cone. It is not shown in the figure, but it is not difficult to associate it;

[0046] At this time, the puncture balloon 3 is decompressed and retracted to its original shape, so that the puncture balloon is taken out and the endoscope 4 is inserted to perform surgery on the lesion of the patient.

[0047] Example 2

[0048] This embodiment provides another visual puncture expander, as shown in the attached manual. Figure 4-6 As shown, it mainly includes a fixed handle 7, a movable handle 8, a nut 9, a covering film 2, an endoscope 4, a support rod 5 and a bracket 6;

[0049] The handle is extended outward from one side of the support plate 1 in the embodiment 1, and one end surface protrudes upward to form a threaded boss 71, and then the support plate 1, the handle, and the threaded boss 71 are produced in an integrated manner to form a fixed handle 7;

[0050] In addition, the moving handle 8 is a disc-shaped member with a handle, and there is a through hole at the center for conveniently passing through the threaded boss 71, so that the moving handle 8 can be sleeved over the fixed handle 7 from top to bottom, and then fixed by the nut 9.

[0051] In this embodiment, the installation method of the support rod 5 is similar to that of the support rod 5 in Embodiment 1, but there are modifications. Please refer to the attached Figure 5-6 as follows:

[0052] 1. Change the L-shaped connecting piece 51 to a C-shaped connecting piece 52;

[0053] 2. The rectangular through slot is changed from the original way of setting the bayonet 13 to not setting the bayonet 13 and penetrating the upper and lower side walls;

[0054] For details, please refer to the attached Figure 4-5 . The rectangular through slot 11 penetrates the upper and lower side walls of the support disc 1. The end of the support rod 5 inserted into the rectangular through slot 11 is fixedly connected to the C-shaped connecting piece 52. A round pin 511 is correspondingly installed at the position of the C-shaped connecting piece 52 corresponding to the round pin hole 12. The C-shaped connecting piece 52 rotates inside the rectangular through slot 11 through the round pin hole 12 and the round pin 511, and the support rod 5 rotates around the round pin hole 12 of the support disc 1;

[0055] Continue to refer to the attached Figure 5 . The upper end of the C-shaped connecting piece 52 perpendicular to the support rod 5 is set as an inclined surface that gradually thins from inside to outside, and the lower end of the C-shaped connecting piece 52 is fixedly connected to the support rod 5.

[0056] It is worth mentioning that several semi-circular convex platforms are arranged at equal circumferential intervals on the side of the moving handle 8 close to the fixed handle 7. In this embodiment, the number of semi-circular convex platforms is set equal to the number of support rods 5, and both are set to six.

[0057] In addition, a bracket 6 is provided outside the expansion cavity formed by the six support rods 5. The bracket 6 is sleeved on the outer surface of the uniformly distributed support rods 5, and the film 2 is sleeved on the outer surface of the bracket 6;

[0058] Please refer to the attached Figure 5 for a specific description of the expansion method of the support rod 5 in this embodiment: Rotate the moving handle 8, and the uniformly distributed semi-circular convex platforms on its end face will push the support rod 5 and squeeze against the inclined surface at the upper end of the support rod 5. Therefore, the support rod 5 will rotate around the round pin hole on the fixed handle 7, and then撑开 the bracket 6 and the film 2. When the support rod 5 is opened to the maximum position, its short side is stuck in the bayonet on the fixed handle 7;

[0059] Specifically, as the semi-circular boss 81 continuously moves towards the upper end of the C-shaped connector 5, since the surface of the semi-circular boss 81 is arc-shaped, when the semi-circular boss 81 moves to the vertex and just squeezes against the upper end of the C-shaped connector 52, the rotation degree of the C-shaped connector 52 is the largest. At this time, the support rod 5 expands to the maximum extent, that is, the bracket 6 is opened to the maximum extent.
