Description

Technical Field

[0001] The utility model relates to the technical field of endoscopic surgical equipment, in particular to an intragastric support device for endoscopic surgery. Background Art

[0002] During endoscopic surgery, the gas in the stomach cavity will enter the abdominal cavity through the perforated wound, causing the filled stomach cavity to contract, narrowing the surgical field of view, increasing the difficulty of gastroscopy and prolonging the operation time. In order to ensure a clear surgical field of view, the surgeon has to continue to inject gas and water into the stomach cavity. Some of the gas, water and secretions in the stomach will continue to enter the abdominal cavity, causing excessive abdominal gas accumulation and unstable vital signs, excessive abdominal fluid accumulation and abdominal infection.

[0003] Therefore, some intragastric support devices used in endoscopic surgery have appeared on the market, such as the utility model patent CN208372278U, which discloses such a device. However, these existing intragastric support devices have the following problems:

[0004] 1. The size cannot be adjusted and cannot adapt to stomach environments of different sizes.

[0005] 2. When such support devices need to be withdrawn after the operation, they are usually removed from the gastroscopic catheter after vacuuming. However, due to incomplete vacuuming or the material being deformed during inflation and unable to recover, the catheter may be blocked during the extraction process and cannot be removed.

[0006] To this end, the present application designs an intragastric support device for endoscopic surgery to solve the above-mentioned problems. Utility Model Content

[0007] In order to make up for the deficiencies in the prior art, the utility model provides an intragastric support device for endoscopic surgery.

[0008] An intragastric support device for endoscopic surgery, comprising a catheter, characterized in that:

[0009] A central air tube is pullable inside the catheter, the bottom of which is connected to one end of a plurality of supporting air tubes, the other ends of which pass through the catheter and are connected to a hard hand-held ring arranged outside the top end of the catheter, and the hand-held ring can movably clamp the supporting air tubes.

[0010] Furthermore, in order to better implement the utility model, a quick connector is connected to the top end of the central air pipe, and the quick connector is detachably connected to an air pump.

[0011] Furthermore, in order to better implement the utility model, the top end of the supporting air tube is blocked and fixedly connected to the bottom of the hand-held ring.

[0012] Furthermore, in order to better realize the utility model, an L-shaped support rod is fixedly connected to the top of the hand-held ring, and a threaded through hole is opened horizontally on the support rod. A stud is threaded in the threaded through hole, and the end of the stud is rotatably connected to a clamping block through a bearing. The clamping block is attached to the surface of the supporting air pipe, and the hand-held ring is fixed to the supporting air pipe by increasing friction.

[0013] Furthermore, in order to better realize the utility model, the length of the central trachea and the supporting trachea extending to the outside of the bottom of the catheter can be adjusted, thereby changing the volume of the space in the stomach supported after inflation. The shape of the supporting body after inflation can be changed by adjusting the position of the hand-held ring relative to the central trachea, and the supporting trachea can be made close to the central trachea during recovery to facilitate the overall recovery into the catheter.

[0014] The beneficial effects of the utility model are:

[0015] The device of the present invention can control the size of the support volume by adjusting the extended length to adapt to the intragastric environment of different volumes. In addition, the present invention can control the position of the support trachea relative to the central trachea through a hand-held ring. Firstly, the shape after inflation can be changed, and secondly, the support trachea can be made close to the central trachea during recovery, so as to facilitate the overall collection into the catheter.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0022] Figure 1-Figure 2 This is a specific embodiment of the utility model, which is an intragastric support device for endoscopic surgery. A central trachea 2 can be pulled out in a catheter 1. The bottom of the central trachea 2 is connected to one end of a plurality of supporting tracheas 4. The other ends of these supporting tracheas 4 pass through the catheter 1 and are connected to a hard hand-held ring 3 arranged outside the top of the catheter 1. The hand-held ring 3 can movably clamp the supporting trachea 4. A quick connector 201 is connected to the top of the central trachea 2. The quick connector 201 is detachably connected to an air pump. The top of the supporting trachea 4 is blocked and fixedly connected to the bottom of the hand-held ring 3. An L-shaped support rod 301 is fixedly connected to the top of the hand-held ring 3. The support rod 301 is horizontally provided with a threaded through hole. A stud 302 is threadedly connected in the threaded through hole. The end of the stud 302 is rotatably connected to a clamping block 303 through a bearing. The clamping block 303 is attached to the surface of the supporting trachea 4, and the hand-held ring 3 is fixed to the supporting trachea 4 by increasing the friction force. The length of the central trachea 2 and the supporting trachea 4 extending to the outside of the bottom of the catheter 1 can be adjusted, thereby changing the volume of the space in the stomach supported after inflation. The shape of the supporting body after inflation can be changed by adjusting the position of the hand-held ring 3 relative to the central trachea 2, and the supporting trachea 4 can be made close to the central trachea 2 during recovery to facilitate the overall recovery into the catheter 1.

[0023] The specific usage method of this embodiment is as follows:

[0024] The central trachea 2 can be extended to the outside of the bottom of the catheter 1 together with the supporting trachea 4. By adjusting the length of the supporting trachea 4, the overall shape after inflation can be changed. After that, the air pump works, and the gas enters the supporting trachea 4 from the central trachea 2 and expands to hold the inner wall of the stomach. When the device needs to be withdrawn after the operation is completed, in order to avoid the supporting organ 4 being blocked at the port of the catheter 1 and unable to be withdrawn, the stud 302 can be loosened after the air pump is evacuated, so that the clamping block 303 no longer rubs the central trachea 2, and the central trachea 2 is delivered downward while the hand-held ring 3 is pulled upward, so that the exposed part of the supporting trachea 4 can be tightly attached to the central trachea 2, and then the stud 302 is tightened, so that the central trachea 2 and the supporting trachea 4 can be recovered into the catheter 1 without hindrance.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
