Description

Porous catheter device with puncture aid structure and method of use thereof

The present invention relates to a porous catheter device and method of use thereof, and more particularly to a porous catheter device having a puncture-assisted structure and methods of use thereof.

Minimally invasive surgery has the advantages of small wounds, beautiful wounds, less bleeding, low infection probability, and quick recovery. It has become a new trend in surgical surgery, such as arthroscopy and laparoscopic surgery. Traditionally, during minimally invasive surgery, the surgeon must first puncture an opening in the patient's skin surface and then use a catheter to open the opening to maintain communication between the inside and outside of the skin and to pass the endoscope or surgical instrument via the endoscope or surgical instrument. The catheter extends into the patient's skin for surgery. In the process of operating such minimally invasive surgery, a complete sealing mechanism is often required to ensure the isolation of the inside and outside of the body, so the surgeon will use a catheter with a sealing effect to achieve internal and external isolation and surgical safety.

Although minimally invasive surgery has many of the above advantages, conventional catheters still present some serious problems. For example, when multiple surgical devices are operated simultaneously under a single tunnel (such as simultaneous operation of an endoscope or a surgical instrument), mutual interference is likely to occur, so that the surgical device cannot be smoothly moved to a desired position. In addition, conventional catheters are soft or semi-soft materials that often require additional rigid puncture aids to be combined with one another to effect the puncture step, thereby piercing the catheter into the patient's skin. After the catheter is inserted and positioned, the hard puncture support structure is also pulled out of the tunnel, and the surgical device can be inserted into the tunnel to perform the operation. This surgical procedure is quite complicated and extremely inconvenient to operate, which easily causes the operation to fail and greatly increases. The risk and difficulty of surgery. Therefore, there is currently a lack of catheters that can be directly penetrated into the body, have high sealing, simple operation, reduced mutual interference using multiple surgical equipments, and can meet the needs of different types of surgical equipment, so the relevant industry is seeking solutions.

In addition, the front end of the device is pointed and hard, which can be used to puncture the skin without additional matching with other puncture structures. Therefore, the device can be directly worn and limited to the endoscope and the surgical device after puncture of the surgical site.

Hereinafter, a plurality of embodiments of the present invention will be described with reference to the drawings. For the sake of clarity, many practical details will be explained in the following description. However, it should be understood that these practical details are not intended to limit the invention. That is, in some embodiments of the invention, these practical details It is not necessary.

Referring to FIGS. 1 to 5 together, FIG. 1 is a perspective view showing a porous catheter device 100 having a puncture support structure according to a first embodiment of the present invention. Fig. 2A is an exploded perspective view showing the porous catheter device 100 having the puncture support structure of Fig. 1 in the first direction.

FIG. 3B is a schematic view showing the two body through-holes 210 of the porous catheter device 100 with the puncture-assisted structure of FIG. 1 extending across the outside of the device. Fig. 4A is a plan view showing the porous catheter device 100 having the puncture support structure of Fig. 1. Fig. 4B is a perspective perspective view of the porous catheter device 100 having the puncture support structure of Fig. 1. Fig. 5 is a schematic view showing the operation of the porous catheter device 100 having the puncture support structure of Fig. 1. As shown, a multi-hole catheter device 100 with a puncture aid structure is used to guide the endoscope 110 and the surgical instrument 120. The porous catheter device 100 with the puncture aid structure includes a porous channel body 200, a puncture tip 300, a cover 400, and a gasket 500.

The porous channel body 200 includes two body through holes 210, a proximal end 220, a distal end 230, and a horizontal relief 240. The two body through holes 210 are independent of each other and the extending directions of the two body through holes 210 are different from each other. The two body perforations 210 are spaced apart from one another by a perforation spacing that gradually changes from the proximal end 220 toward the distal end 230. In detail, the spacing of the perforations is at the proximal end 220 For a first distance D1, the pitch of the perforations is a second distance D2 at the distal end 230. The first distance D1 is greater than the second distance D2. In addition, the two body through holes 210 extend outward to form two virtual holes 212, and each of the body through holes 210 and each of the virtual holes 212 are linear. The spacing of the perforations is gradually reduced from the proximal end 220 toward the distal end 230, and the two virtual channels 212 intersect outside the porous channel body 200 to form an included angle θ greater than 0 degrees and less than 45 degrees. The horizontal relief 240 is disposed on the outer wall of the porous track body 200. The horizontal relief 240 of the present embodiment has five strips which are disposed parallel to each other and equally spaced. Furthermore, the proximal end 220 includes two lugs 222 respectively located on opposite sides of the proximal end 220. The two lugs 222 are used to synchronously rotate the multi-channel body 200 and the puncture tip 300. Therefore, the present invention utilizes a separate porous channel to place the endoscope 110 and the surgical instrument 120, which not only avoids mutual interference, but also is quite convenient to operate, which is a great boon for medical personnel. In addition, these independent porous channels have a specific direction, allowing the endoscope 110 to intersect with the surgical instrument 120 at the surgical site, facilitating manipulation by medical personnel, thereby shortening the operation time and increasing the safety of the operation, so as to solve the conventional multiple surgical equipment. The problem of mutual interference is easy in a single channel.

The puncture tip 300 is integrally connected to the distal end 230 of the multi-channel body 200. The puncture tip 300 includes two puncture holes 310 and a ring protrusion 320. Two puncture holes 310 respectively engage the two body perforations 210. The endoscope 110 can extend through one of the body perforations 210 and the corresponding puncture hole 310, and the surgical instrument 120 can extend through the other body perforation 210 and the other puncture hole 310, as shown in FIG. Further, the puncture tip 300 is made of a rigid material, and the puncture tip 300 has a sharp vertex shape. wear An annular projection 320 is provided at the intersection of the spiking tip 300 and the distal end 230 of the porous channel body 200. The cross-section of the piercing tip 300 at the junction is larger than the cross-section of the distal end 230, that is, the cross-sectional area of the ring-shaped projection 320 is greater than the cross-sectional area of the distal end 230. Thereby, the porous catheter device 100 of the puncture-assisted structure of the present invention penetrates the skin through the pointed hard puncture tip 300 without additional matching with other puncture structures, so that the device can be directly worn after puncture of the surgical site. The endoscope 110 and the surgical instrument 120 are limited, thereby simplifying the surgical procedure and increasing the convenience of operation, so as to solve the problem that the conventional puncture structure assistance is required to cause inconvenience in operation.

The cover 400 is constructed of a soft material and the cover 400 covers the proximal end 220 of the porous track body 200. The cover 400 includes two cover holes 410, an accommodation space 420, a recess 430, and an inner top surface 440. The two cover holes 410 are all circular and respectively correspond to the two body through holes 210 and the two puncture holes 310. The accommodating space 420 is connected to the two cover holes 410 and is located inside the cover 400. The slot 430 is annular and corresponds to the outer contour of the cover 400. The slot 430 is disposed on the inner side of the cover 400 and is connected to the accommodating space 420. The shape of the slot 430 corresponds to the shape of the proximal end 220. In other words, the slot 430 is looped along the inner edge of the cover 400 to fit and wrap the entire proximal end 220. The inner top surface 440 faces the accommodating space 420.

The gasket 500 is made of a soft material, and the gasket 500 is located between the cover 400 and the proximal end 220 and disposed in the accommodating space 420. The washer 500 has two washer openings 510 that are multi-lobed and correspond to the two cover holes 410 of the cover 400, respectively. The gasket opening 510 of the embodiment is formed by three flaps, and when no foreign object is inserted into the gasket opening 510 At the same time, the gasket opening 510 is closed, causing the three flaps to be joined. When a foreign object is inserted into the gasket opening 510 (such as the endoscope 110 or the surgical instrument 120), the gasket opening 510 is open, so that the three flaps are in close contact with the surface of the foreign object. The upper and lower sides of the gasket 500 closely fit the inner top surface 440 of the cover 400 and the proximal top surface 224 of the proximal end 220, respectively. In addition, the upper portion of the accommodating space 420 has a gasket accommodating groove having the same shape as the gasket 500 adjacent to the cover hole 410. The depth of the gasket accommodating groove is equal to the thickness of the gasket 500, so that the gasket 500 is seamlessly engaged with the gasket accommodating groove. . Therefore, the present invention utilizes the detachable cover 400 and the gasket 500 to enable the proximal end 220 of the porous passage body 200 to produce a gas-tight effect. When the porous catheter device 100 having the puncture-assisted structure penetrates into the skin, it can effectively isolate the inside and outside of the skin. And significantly reduce the risk of infection at the surgical site. In addition, it is worth mentioning that, since the structure of the embodiment only includes two holes, which are respectively used for setting the endoscope 110 and the surgical instrument 120, if the medical staff needs to flush or absorb water at the surgical site to increase the visibility, After the endoscope 110 is combined with the endoscope 110, a corresponding suction hole assembly (such as an endoscope sheath) is used to sequentially insert the corresponding cover hole 410, the gasket opening 510, the body through hole 210, and the puncture hole 310. It can be inferred from the above that the apertures of the cover hole 410, the gasket opening 510, the body through hole 210 and the puncture hole 310 are larger than the aperture of the suction sleeve assembly, and the aperture of the suction sleeve assembly is larger than the aperture of the endoscope 110, so that The suction sleeve assembly and the endoscope 110 are freely threaded into the porous catheter device 100 having the puncture aid structure.

Referring to FIGS. 6A and 6B, FIG. 6A is a plan view showing a porous catheter device 100a having a puncture support structure according to a second embodiment of the present invention. Figure 6B shows the puncture-assisted junction of Figure 6A An exploded perspective view of the porous catheter device 100a. As shown, the porous catheter device 100a having a puncture support structure includes a porous channel body 200a, a puncture tip 300a, a cover 400a, and a gasket 500a. The porous track body 200a includes two body perforations 210a, a proximal end 220a, a distal end 230a, a horizontal relief 240, and a staggered region R. The staggered region R is located in the porous channel body 200a and is between the proximal end 220a and the distal end 230a. Each of the body through holes 210a is linear, and the two body through holes 210a are staggered with each other in the staggered region R, and the staggered region R is a porous channel. A cross-sectional area of the body 200a, the two body through-holes 210a on the staggered area R are closest to each other (i.e., the pitch of the perforations). In other words, the pitch of the perforations is gradually reduced from the proximal end 220a toward the staggered region R, and the perforation pitch is gradually increased from the staggered region R toward the distal end 230a. Furthermore, the puncture tip 300a includes two puncture holes 310a, and the two puncture holes 310a respectively engage the two body through holes 210a. The cover 400a and the washer 500a are different from the cover 400 and the washer 500 of the first embodiment only in that the cover holes 410 and 410a and the washer openings 510 and 510a of the two embodiments are different in position, and the two cover holes 410a of the cover 400a correspond to the two. Two washer openings 510a of the washer 500a, two body through holes 210a of the porous track body 200a, and two puncture holes 310a of the puncture tip portion 300a.
