[0027] like Figure 1 and Figure 2 As shown, this embodiment provides a visual puncture, injection, and reaming device, including a reaming body and a tracker. The reaming body includes, from the inside out, a guide rod 10, a reamer 20, and an outer sleeve 30. The guide rod 10 is located innermost, the reamer 20 is movably mounted on the outside of the guide rod 10, and the outer sleeve 30 is movably mounted on the outside of the reamer 20.
[0028] The guide rod 10 of this embodiment is in the shape of a hollow tube. The distal end of the guide rod 10 has a sharp puncture portion 11. The puncture portion 11 extends out of the distal end of the reamer 20. The puncture portion 11 can save the scalpel used for opening, making the operation simpler. The proximal end of the guide rod 10 extends out of the proximal end of the reamer 20 and is detachably connected to the tracker. Figure 5 In this embodiment, the liquid injection port 12 at the distal end of the puncture portion 11 is preferably tilted at a certain angle relative to the axial direction of the guide rod 10 to increase the sharpness of the puncture portion 11.
[0029] The reamer 20 of this embodiment includes a reaming tube 21 and a grip 22. The distal end of the reaming tube 21 preferably has a conical reaming tip 23, which extends beyond the distal end of the outer sleeve 30 to facilitate reaming. The grip 22 is connected to the distal end of the reaming tube 21, allowing medical personnel to grasp the grip 22 and rotate the reamer 20. The grip 22 of this embodiment is preferably T-shaped, with the distal end of the grip 22 connected to the reaming tube 21 and the proximal end of the grip 22 extending perpendicularly from both sides of the reaming tube 21, making it easier for medical personnel to apply torque to the grip 22.
[0030] The outer cannula 30 of this embodiment comprises an outer tube body 31 and a handle 32. The distal end of the outer tube body 31 has a sharp insertion portion 35 that extends axially from the sidewall of the outer tube body 31 toward the distal end, facilitating insertion of the outer tube body 31 into the body to establish a working channel. The proximal end of the outer tube body 31 is connected to the distal end of the handle 32. The outer circumferential wall of the handle 32 has outwardly protruding ears 33 on both sides, making the handle 32 easier to grip. The outer tube body 31 is movably mounted on the outer reamer tube 21 of the reamer 20. The proximal end of the handle 32 is detachably connected to the distal end of the grip 22 of the reamer 20. When the grip 22 and handle 32 are connected, the reamer 20 and the outer cannula 30 can move synchronously. When the grip 22 and handle 32 are separated, the outer cannula 30 can move axially and rotate circumferentially relative to the reamer 20.
[0031] The tracker of this embodiment includes a reference frame 40, the top of the reference frame 40 has multiple branches for installing lamp beads, and the bottom of the reference frame 40 is provided with a sleeve 41, which is detachably connected to the proximal end of the guide rod 10 through a clamp or directly detachably connected to the handheld part 32.
[0032] The structure of the visualized puncture, injection and reaming device of this embodiment is compact, and can realize multiple operations such as puncture, reaming and building a working channel. The tracker can be installed on the guide rod 10 or the outer sleeve 30 according to the use requirements, thereby ensuring the accuracy of the device during operation. When the tracker is installed on the guide rod 10, the tracker can be used to locate the puncture part 11 at the distal end of the guide rod 10, ensuring that the guide rod 10 accurately punctures the target position in the body. In the process of the guide rod 10 puncturing the target position, the drug pipeline can be connected to the Luer interface 55 at the proximal end of the clamp 50 as needed, so as to facilitate the simultaneous injection of anesthetics when the guide rod 10 punctures. After the tracker is removed from the proximal end of the guide rod 10, the guide rod 10 can be left in the body as needed to replace the guide wire or Kirschner wire, making the function of the guide rod 10 diversified. When the tracker is installed on the outer sleeve 30, the tracker can be used to locate the distal end of the outer sleeve 30, ensuring that medical personnel can perform surgery on the target position through the working channel inside the outer sleeve 30.
[0033] See Figure 3The sleeve 41 of this embodiment is preferably connected to the guide rod 10 through a clamp 50. The clamp 50 includes a clamping shell 51 and a clamping jaw 52. The clamping shell 51 is cylindrical and hollow inside. There are at least two clamping jaws 52, and the clamping jaws 52 are arranged in a circular array on the end face of the distal end of the clamping shell 51 to clamp the guide rod 10 between the clamping jaws 52. A clamping nut 53 is sleeved on the clamping jaw 52, and the clamping nut 53 is screwed to the distal end of the clamping shell 51. The clamping force of the clamping jaw 52 is adjusted by adjusting the screwing length of the clamping nut 53. The proximal end of the clamping shell 51 of this embodiment is connected to a Luer interface 55. The proximal end of the guide rod 10 can pass through the interior of the clamping shell 51 and be connected to the distal end of the Luer interface 55. The proximal end of the Luer interface 55 is used to connect to the drug delivery pipeline.
[0034] The distal ends of at least a portion of the jaws 52 of this embodiment are further provided with a limit block 54 protruding outward, and the limit block 54 is used to limit the compression nut 53 from directly slipping off the distal ends of the jaws 52. The clamp 50 of this embodiment specifically includes four jaws 52 in a circular array, and the four jaws 52 can clamp the guide rod 10 firmly. Limit blocks 54 are provided on two of the jaws 52 located on opposite sides to prevent the compression nut 53 from slipping off. It should be noted that the specific structure and principle of the jaws 52 cooperating with the compression nut 53 to clamp the rod are prior art, and the number of jaws 52 and limit blocks 54 can be set according to actual needs, which will not be elaborated in this embodiment.
[0035] The outer peripheral wall of the clamping shell 51 of this embodiment forms a first clamping portion, and the second clamping portion 34 is formed on the hand-held portion 32 of the outer sleeve 30. The sleeve 41 is detachably connected to the first clamping portion and the second clamping portion 34. The sleeve 41 is preferably provided with a U-shaped clamping opening 42. The contours of the first clamping portion and the second clamping portion 34 are adapted to the clamping opening 42. The U-shaped clamping opening 42 facilitates the disassembly and assembly of the sleeve 41. This embodiment is simple in structure and easy to install by providing the first clamping portion and the second clamping portion 34 with the same contour to connect the sleeve 41. The second clamping portion 34 is preferably formed on the distal side of the support ear 33 to facilitate the sleeve 41 to be sleeved onto the hand-held portion 32 from the distal end.
[0036] See Figure 4 The snap assembly of this embodiment preferably includes a snap protrusion 62 and at least two snap arms 60. The snap arms 60 are disposed on the outer peripheral wall of the distal end of the grip portion 22, and have snap grooves 61 defined on the inwardly facing sides of the snap arms 60. The snap protrusion 62 is correspondingly disposed at the proximal end of the handle portion 32. The snap protrusion 62 extends circumferentially and has a clearance notch 63 formed therein for the snap arms 60 to pass through, thereby enabling the snap grooves 61 on the snap arms 60 to engage with the snap protrusions 62.
[0037] When the snap assembly needs to be engaged, the snap arm 60 is first inserted into the avoidance notch 63 so that the snap groove 61 on the snap arm 60 is aligned with the snap protrusion 62. Then, the snap arm 60 and the snap protrusion 62 are rotated relative to each other so that the snap protrusion 62 moves into the snap groove 61. When the snap assembly needs to be unlocked, the snap arm 60 is first rotated to the avoidance notch 63 and then the snap arm 60 is pulled out of the avoidance notch 63. The snap assembly is simple to operate and easy to use. The snap protrusion 62 of this embodiment is preferably arranged between the lugs 33, so that the lugs 33 are not only convenient to hold, but also can limit the rotation angle of the snap arm 60 relative to the snap protrusion 62, preventing the snap arm 60 from rotating to other avoidance notches 63.
[0038] When performing surgery using the visualized puncture, injection and reaming device of this embodiment, the tracker is first installed on the guide rod 10, and the snap assembly between the outer sleeve 30 and the reamer 20 is combined. The guide rod 10 is first accurately punctured to the desired position with the assistance of the tracker; then the tracker is removed from the guide rod 10 and installed on the outer sleeve 30, and the distal end of the reamer 20 is inserted into the area to be expanded under the guidance of the guide rod 10; next, the snap assembly between the outer sleeve 30 and the reamer 20 is unlocked, and the outer sleeve 30 moves toward the target position under the guidance of the reamer 20, and the distal end of the outer sleeve 30 can be accurately moved to the target position with the assistance of the tracker; finally, the reamer 20 is removed from the proximal end of the outer sleeve 30, and the guide rod 10 can be removed or left in the body following the reamer 20 as needed, and medical personnel can perform surgery on the target position through the outer sleeve 30.
[0039] It should be noted that the proximal and distal ends in this embodiment are referenced to the medical staff, with the portion facing the medical staff being the proximal end and the portion facing the patient being the distal end. The movable connection in this embodiment specifically refers to the ability of the two connected parts to move axially and rotate circumferentially relative to each other without any limit. Because the integration of optical navigation technology and other navigation technologies with surgical instruments to assist surgery is relatively common, the specific principles and components of the optical navigation technology will not be elaborated in this embodiment.
[0040] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0041] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
