Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a multifunctional colorectal occluder delivery sheath and an operating system. Background Art

[0002] During colorectal surgery, in order to facilitate the expansion of the surgical field and space, air is introduced into the intestine through the patient's anus to make the intestinal segment bulge. However, since the upper and lower digestive tracts of the human body are connected, the gas will rise to the upper digestive tract, causing discomfort in the patient's stomach, nausea, vomiting, etc.

[0003] The patented technology with publication number CN112891714A discloses a occluder for colorectal surgery. This technology includes a catheter and an airbag occluder. During use, the occluder is placed above the surgical site through the catheter. First, the occluder is inflated to seal the upper part of the colorectum, and then the lower part of the colorectum is inflated to establish pneumoperitoneum in the intestine, thus facilitating subsequent intestinal surgical operations. However, in this technical solution, since the catheter and the airbag are of an integrated structure, during clinical use, the catheter is always inside the intestine, which will affect the surgical operation to a certain extent.

[0004] The patented technology with publication number CN118044854A discloses a visible colorectal operating system for anal access, which solves the problems existing in the above patented technology (CN112891714A) by designing the airbag occluder and the catheter as a detachable structure. However, in this technical solution (CN118044854A), the physiological curvature of the upper part of the colorectum is not considered. In actual operation, the delivery sheath is required to be able to turn, be visible, and be conveniently docked with the occluder. In addition, before and after the operation, it is necessary to perform preoperative exploration and postoperative evaluation on the intestinal segment and the lesion site, and the use cost of existing instruments is relatively high and the operation is relatively complex.

[0005] Based on this, it is necessary to develop a multifunctional colorectal occluder delivery sheath and an operating system to solve the above technical problems. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The principles and features of the present utility model will be described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0028] Embodiment 1

[0029] As Figure 1 and 2 shown, the multi-functional colorectal occluder delivery sheath of this embodiment includes a sheath tube 1. An external thread joint 11 is provided at the distal end of the sheath tube 1. A pressing tube column 12 is provided inside the external thread joint 11. An air passage gap is formed between the pressing tube column 12 and the inner wall of the external thread joint 11. The sheath tube 1 is a transparent tube, and a first camera 2 is installed inside its distal end.

[0030] When the multifunctional colorectal occluder delivery sheath of this embodiment is used clinically, it can be inserted into the patient's intestine through the anus. During the insertion process, the first camera 2 takes real-time images of the intestine through the transparent sheath tube 1, and then feeds the images back to the externally adapted host instrument, enabling the doctor to visually insert the sheath tube 1 through the anus into the intestine. At the same time, according to the captured images, it can play a role in detecting intestinal lesions. That is to say, the entire insertion process can achieve visual operation and can also play a role in detecting intestinal lesions. In addition, the entire sheath tube 1 can be connected to the adapted balloon occluder through the external thread joint 11. After inflation, the inflated balloon occluder is used to block the intestine, and the sheath tube 1 can also act as an air supply pipeline. Overall, the structural design is simple, reasonable, and has diversified functions, serving multiple purposes with one object. It can not only simplify the surgical process but also endow the sheath tube 1 with multifunctional operations, enabling operations such as intestinal exploration, delivery, inflation, and visual navigation to be achieved using this sheath tube, effectively reducing the patient's surgical cost and improving the problem of using other expensive instruments for exploration.

[0031] In this embodiment, the first camera 2 can be connected to the relevant host instrument through a cable that passes through the proximal end of the sheath tube 1.

[0032] As a preferred embodiment, the above-mentioned external thread joint 11 is provided with a magnetic member.

[0033] In the above-mentioned implementation, by setting a magnetic member on the external thread joint 11, such a design enables the external thread joint 11 to utilize the adsorption effect of the magnetic member with other magnets or metal parts (the other magnets or metal parts are arranged at the docking part of the balloon occluder) when docking with the occluder in the field, so as to play a guiding role for the distal end of the sheath tube 1, enabling the external thread joint 11 at the distal end of the sheath tube 1 to quickly dock with the balloon occluder.

[0034] In this embodiment, the above-mentioned magnetic member is a permanent magnet ring 111 provided at the end of the above-mentioned external thread joint 11. It will not change the shape of the external thread joint 11 and is relatively convenient to use.

[0035] In this embodiment, since the sheath tube 1 needs to be advanced and inserted into the intestinal segment, and the intestinal segment has a tortuous trend, in order to enable the sheath tube 1 to smoothly pass through the curved segment of the intestinal segment, the following several forms are adopted to achieve this:

[0036] 1) The above-mentioned sheath tube 1 is set as a universal catheter, and the distal direction of the universal catheter can be adjusted at the proximal end of the sheath tube 1. Its specific structure belongs to the prior art and will not be elaborated here.

[0037] 2) The distal end of the above-mentioned sheath tube 1 is set as an easily bendable section, and the sheath tube 1 is provided with a steering drive structure connected to the easily bendable section.

[0038] More specifically, an inner lumen is provided on the side wall of the sheath tube 1 along its length direction, and a traction wire 13 is provided in the inner lumen. One end of the traction wire 13 is connected to the outer wall of the easy-to-bend section, and the other end of the traction wire 13 passes through the proximal side wall of the sheath tube 1 and is connected to a driving member 14 for traction and pulling it. The traction wire 13 and the driving member 14 constitute the steering drive structure.

[0039] In the above embodiment, the driving member 14 is used to pull the traction wire 13, so that the traction wire 13 pulls the bendable section to bend relative to the main body of the sheath tube 1, thereby achieving smooth "bending" of the sheath tube 1 in the intestine.

[0040] In this embodiment, the driving member 14 is a knob rotatably arranged on the proximal side wall of the sheath tube 1, and the other end of the traction wire 13 is wound around the knob. In the specific operation process, by turning the knob, the other end of the traction wire 13 can be wound and tightened, that is, the traction effect on the easy-to-bend section can be achieved, so that the easy-to-bend section can be effectively bent.

[0041] In this embodiment, a developing ring is provided at the distal end of the sheath tube 1. The developing ring can provide feedback on the position of the distal end of the sheath tube 1 on an external developing instrument.

[0042] Example 2

[0043] like Figure 3 As shown, the multifunctional colorectal closure operating system of the present embodiment includes an airbag closure 3 and the multifunctional colorectal closure delivery sheath in Example 1, a mounting portion 31 is provided in the middle area of one end of the airbag closure 3, a charging and releasing pressure port 311 connected to the inner cavity of the airbag closure 3 is provided on the mounting portion 31, a valve core 312 adapted to the top pressure column 12 is encapsulated in the charging and releasing pressure port 311, an inner wall of the charging and releasing pressure port 311 is provided with an internal thread, the external threaded connector 11 extends into the charging and releasing pressure port 311 and is screwed together, the charging and releasing pressure port 311 is configured as a metal part that can be adsorbed by the magnetic part, and the port of the charging and releasing pressure port 311 is expanded.

[0044] During the operation, the multifunctional colorectal closure system of the present embodiment can realize the exploration of intestinal lesions through a separate delivery sheath, so that the exploration can be carried out under the condition of visual navigation. In addition, after the exploration is completed, the airbag closure device 3 can be screwed on the distal external threaded joint 11 of the sheath tube 1, and the airbag closure device 3 can be delivered to the intestinal closure point through the anus by using the sheath tube 1. After arriving, the airbag closure device 3 is inflated by using the proximal end of the sheath tube 1 to expand it and achieve the closure of the intestine (when the external threaded joint 11 is docked with the filling and release pressure port 311 of the airbag closure device 3, as the two are relatively tightened, the top pressure column 12 will push the core rod of the valve core 312, thereby opening the air path, so that the external The gas can smoothly rush into the airbag sealer 3). After the sealing is completed, the sheath 1 is rotated out, and then the intestinal segment between the sealing point and the anus is inflated to make it bulge, and then the operation on the lesion can be performed in the bulged intestinal segment. After the operation is completed, the sheath 1 enters the intestine again, and the external threaded connector 11 is used to dock and screw with the filling and release pressure port 311. During the docking process, the end of the external threaded connector 11 and the filling and release pressure port 311 can be quickly docked by the attraction between the magnetic part and the metal part or the magnet. The pressure release port 311 is then screwed tightly, the valve core 312 is opened, and the sheath 1 is used to release pressure and deflate, and then the sheath 1 is used to take the airbag sealer 3 out of the body. The whole operation process is simple and fast.

[0045] It should be noted that the expansion setting of the port of the filling and releasing pressure port 311 makes it convenient for the external threaded connector 11 to slide along the inner wall of the expanded port of the filling and releasing pressure port 311 to achieve effective hole matching with the unexpanded section when the sheath tube 1 is docked, which is beneficial to the subsequent screwing and docking operation.

[0046] It should be supplemented that: in this embodiment, the sheath tube 1 and the inflated balloon closure device 3 can be used to pull the intestinal segment (in conjunction with laparoscopic surgery to pull the intestinal segment).

[0047] In this embodiment, the airbag sealer 3 is a transparent airbag, a wireless transmission module 5 is provided inside the mounting portion 31, and a pressure sensor (indicated by b in the figure) connected to the wireless transmission module 5 is embedded in the airbag sealer 3. The pressure data in the intestinal segment can be monitored by the pressure sensor, and the pressure data can be fed back to an external host or instrument through the wireless transmission module 5, so as to intuitively display the internal pressure of the bulging intestinal segment.

[0048] Of course, pressure sensors may be provided at both ends of the airbag sealer 3 and on the internal mounting portion 31, respectively, to monitor the intestinal pressure at both ends of the sealing point.
