Description

Technical Field

[0001] This application relates to the field of da Vinci-assisted thoracoscopic instruments, and more particularly to a multifunctional gastric tube. Background Technology

[0002] Traditional three-incision radical esophagectomy requires an auxiliary incision in the upper midline of the abdomen after laparoscopic minimally invasive dissection of the stomach and lower esophagus. However, this increased number of incisions not only increases the patient's wound (trauma), scarring, pain, infection, poor healing, and hernia problems, but also prolongs the operation time. Furthermore, the increased number of incisions can lead to a series of problems such as significant bleeding. This increased surgical trauma due to additional incisions is seriously inconsistent with modern rehabilitation concepts.

[0003] Current gastric tubes only have drainage and irrigation functions, which are relatively limited. They lack traction and guidance capabilities, and therefore cannot solve the problems described above. The limitations of current gastric tubes are explained in detail below:

[0004] Limitation 1: For example, a Chinese patent, publication number CN 212466812 U, entitled "Anti-slip and Fluffable Intelligent Gastric Tube," discloses an anti-slip and flushable intelligent gastric tube, including: a tube body, a data acquisition and control center, and a terminal device. The front end of the tube body is equipped with a photometer, a CMOS micro-image sensor, and a temperature sensor. A transparent diaphragm is fixed to the front end of the tube body, behind the temperature sensor. Several Moff's eyes are formed on the surface of the tube body, behind the transparent diaphragm. A fixing airbag is fixed to the outer wall of the tube body. The fixing airbag has a ring structure and a pressure sensor installed inside. A wire bundle containing several metal guide wires is installed inside the tube body. This patent has a simple structure. Ordinary gastric tubes have a smooth, thin surface and only have drainage and irrigation functions, making them prone to breakage during placement.

[0005] Limitation 2: For example, Chinese patent publication number CN 206081298 U, entitled "Double-lumen Gastrointestinal Decompression Gastric Tube," discloses a double-lumen gastrointestinal decompression gastric tube. This tube includes a main body, with an inlet end integrally connected to a negative pressure drainage tube. A branch tube is provided on the negative pressure drainage tube. A drug infusion catheter is embedded in the wall of the main body, with its inlet end seamlessly connected to the outlet end of the branch tube. Several through holes are provided on the distal surface of the main body. The distal end of this patented gastric tube has an open structure, which cannot meet the requirements for traction and fixation of the gastric tube during clinical surgery.

[0006] Therefore, there is an urgent need for multifunctional gastric tubes to address, to some extent, the technical problems existing in current technologies. Utility Model Content

[0007] The purpose of this application is to provide a multifunctional gastric tube that, to a certain extent, has multiple functions, including drainage and irrigation, as well as clamping, fixing, and locking functions.

[0008] This application provides a multifunctional gastric tube, including a gastric tube body, a guide wire, and a clamping component;

[0009] The gastric tube body has an inlet end and an outlet end opposite to the inlet end;

[0010] The clamping member is disposed at the insertion end, and the clamping member has a movable cavity communicating with the insertion end; the clamping member extends toward the inlet end and is angled to the outer side wall of the gastric tube body, so that a clamping gap is formed between the clamping member and the gastric tube body.

[0019] In the above technical solution, the clamping component further includes a fixing member;

[0020] The fixing component includes a rotating shaft and at least two rotating blades rotatably connected to the rotating shaft.

[0021] The rotating shaft is disposed at the connection between the connecting part and the gastric tube body; wherein at least one of the rotating pages is connected to the connecting part, and at least another rotating page is connected to the gastric tube body.

[0022] In the above technical solution, the connecting part further includes a connecting body, a support rod, and a connecting rod;

[0023] The connector surrounds one end of the insertion end and is set at the angle to the gastric tube body, so that the clamping gap is formed between the connector and the gastric tube body;

[0024] The support rods are arranged at equal intervals along the circumferential direction of the gastric tube body and are set at an angle to the gastric tube body; the connecting rods are connected between adjacent support rods.

[0025] The guide wire is connected to the support rod via the fixing member; when the guide wire is pulled outward, the support rod moves toward the direction closer to the main body of the gastric tube, reducing the size of the clamping gap; when the guide wire is released inward, the size of the clamping gap increases.

[0026] In the above technical solution, the multifunctional gastric tube further includes a locking component;

[0027] The locking component includes a fixing part and a locking part. The fixing part is disposed on the gastric tube body corresponding to the position of the inlet end. The locking part is sleeved on the portion of the guide wire that protrudes from the gastric tube body.

[0028] When the tissue to be clamped is clamped in the clamping gap, the locking part is screwed onto the fixing part, which allows the fixing part to retract and the guide wire to be fixed to the gastric tube body, so that the tissue to be clamped is in a clamped state.

[0029] In the above technical solution, the fixing part further includes a plurality of arc-shaped plates with external threads arranged at intervals along the circumferential direction; the locking part is a locking nut, which has an internal thread that matches the external thread;

[0030] The locking nut is screwed onto the outer wall of the plurality of arc-shaped plates, which enables the plurality of arc-shaped plates to close and clamp the guide wire.

[0031] In the above technical solution, the multifunctional gastric tube further includes a guide tube;

[0032] The guide tube is attached to the inner wall of the gastric tube body along the extension direction of the gastric tube body, and extends to the inner wall of the connecting part until the clamping member is close to the inlet end;

[0033] The guide wire can extend into the guide tube and along the guide tube to the end of the clamping member near the inlet end.

[0034] In the above technical solution, furthermore, multiple guide wires and multiple guide tubes are provided;

[0035] The multiple guide wires and multiple guide tubes are arranged at intervals along the circumference of the gastric tube body, and the multiple guide wires and multiple guide tubes correspond one-to-one.

[0036] In the above technical solution, the gastric tube body further includes an operating end that is close to the inlet end and opposite to the insertion end; a guide hole is provided at one end of the gastric tube body close to the insertion end, and a one-way valve is provided at the guide hole;

[0037] When liquid is introduced into the gastric tube body through the operating end, the one-way valve enables one-way drainage from inside the gastric tube body to the outside.

[0038] This application also provides a multifunctional gastric tube, including a gastric tube body, a guide wire, and a clamping component;

[0039] The gastric tube body has an inlet end and an outlet end opposite to the inlet end;

[0040] The clamping member is disposed on the extension end via a rotating component, so that the clamping member can be opened or closed at the extension end; when the clamping member opens the extension end, a clamping gap is formed between the clamping member and the extension end;

[0041] The guide wire extends into the gastric tube body through the inlet end and passes through the gastric tube body above the connection between the inlet end and the clamping member, connecting to the end of the clamping member opposite to the inlet end; and a corrugated tube is sleeved at the point where the guide wire passes through the gastric tube body.

[0042] When the tissue to be clamped is located within the clamping gap, pulling and locking the guide wire can cause the tissue to be clamped within the clamping gap.

[0043] Compared with the prior art, this application has the following beneficial effects:

[0044] This application provides a multifunctional gastric tube, including a gastric tube body, a guide wire, and a clamping component;

[0045] The gastric tube body has an inlet end and an outlet end opposite to the inlet end;

[0046] The clamping member is disposed at the insertion end, and the clamping member has a movable cavity communicating with the insertion end; the clamping member extends toward the inlet end and is angled to the outer side wall of the gastric tube body, so that a clamping gap is formed between the clamping member and the gastric tube body.

[0047] The guide wire extends into the gastric tube body through the inlet end and reaches the movable cavity. After the guide wire reaches the movable cavity, it can extend along the inner wall of the clamping member to the end of the clamping member near the inlet end.

[0048] When the tissue to be clamped is located within the clamping gap, pulling and locking the guide wire can cause the tissue to be clamped within the clamping gap.

[0049] In summary, this application modifies the existing gastric tube with a smooth blind end to a gastric tube with a clamping component at the front end. The tubular stomach is clamped through the clamping gap formed by the clamping component. In other words, this application replaces the existing suturing method with a clamping method, thus overcoming the problems of suture breakage risk and surgical complications that occur during traction due to the use of a blind end to suture the tubular stomach in the prior art. In this respect, this application can remove the esophagus and esophageal tumor separately in advance, leaving a guide wire. The drainage and guidance functions in esophageal surgery can be unified without replacing the gastric tube, reducing the risks of esophageal rupture, tumor dissemination and implantation, gastric fluid infiltration, and anastomotic leakage.

[0075] Example 1

[0076] To address the limitations of existing gastric tubes with limited functionality, this application provides a multifunctional gastric tube, which will be discussed below. Figures 1-11 This application provides a detailed description of a multifunctional gastric tube.

[0077] Combination Figure 1As shown, the multifunctional gastric tube includes a gastric tube body 1, a guide wire 2, and a clamping component 3. The gastric tube body 1 has an inlet end 101 and an outlet end 102 opposite to the inlet end 101. Specifically, the outlet end 102 is the end that enters the stomach and is flexible to reduce patient discomfort. The inlet end 101 is opposite to the outlet end 102, meaning it is located on the other side of the gastric tube body 1, i.e., on the outer side of the body. The inlet end 101 serves as the inlet for the guide wire 2, allowing it to extend from the inlet end 101 into the interior of the gastric tube body 1.

[0078] The clamping member 3 is located at the insertion end 102. When the insertion end 102 is inserted into the stomach, the clamping member 3 will also be inserted into the stomach along with the insertion end 102. The clamping member 3 is also made of a soft material, such as polyurethane or silicone, to reduce patient discomfort when inserted into the stomach. Specifically, the clamping member 3 has an open end that connects precisely to the insertion end 102. Furthermore, the clamping member 3 surrounds a movable cavity 301. Since the open end of the clamping member 3 is connected to the insertion end 102, the movable cavity 301 is in communication with the insertion end 102. Further, the portion of the clamping member 3 near the insertion end 102 extends towards the inlet end 101 and is angled to the outer wall of the gastric tube body 1, creating a clamping gap 302 between the clamping member 3 and the gastric tube body 1. The portion of the clamping member 3 near the insertion end 102 extends toward the inlet end 101, which is equivalent to a part of the clamping member 3 being bent from the insertion end 102 side toward the inlet end 101 side. Preferably, the above angle is set between 0° and 90°. In actual operation, this angle can be adjusted by the traction or lengthening (release) of the guide wire 2.

[0079] The guide wire 2 extends into the gastric tube body 1 through its inlet end and connects to the clamping component 3; this connection refers to a fixed connection, meaning that one end of the guide wire 2 is fixedly connected to the clamping component 3. Optionally, a fixed buckle is used for the fixed connection. The fixed buckle is a conventional existing structure and will not be described in detail here.

[0080] In actual use, firstly, pull the guide wire 2 outward, using the guide wire to control the clamping member 3 to extend into the stomach with a clamping gap of 0° or close to 0°; after reaching the stomach, release the guide wire 2, causing the clamping gap 302 to open, and the clamping member 3 to open at an angle of approximately 45°. Then move the gastric tube body 1, allowing the stomach tissue to fill the clamping gap; then lock the guide wire 2 located outside the gastric tube body 1 onto the gastric tube body 1 (note that at this time, the guide wire 2 in the movable cavity 301 provides support for the stomach tissue in the clamping space), so that the stomach tissue is clamped within the clamping gap 302; finally, pull the gastric tube body 1 outward towards the body, pulling the stomach to the esophagus position.

[0081] In summary, this application modifies the existing gastric tube with a smooth blind end to a gastric tube with a clamping member 3 at the front end. The gastric tissue is clamped through the clamping gap formed by the clamping member 3. In other words, this application uses a clamping method to replace the existing suturing method, thus overcoming the problems of suture breakage risk and surgical complications that occur during traction due to the use of blind end and tubular stomach suturing in the prior art. In this respect, this application can remove the esophagus and esophageal tumor separately first, and can achieve the unified drainage and guidance function in esophageal surgery without replacing the gastric tube, reducing the risks of esophageal rupture, tumor dissemination and implantation, gastric fluid infiltration, and anastomotic leakage.

[0082] In this embodiment, combined with Figure 1 And refer to Figure 4 As shown, the clamping member 3 includes a connecting portion 303 and an outer portion 304. The connecting portion 303 surrounds one end of the insertion end 102 and is angled relative to the gastric tube body 1. This angled design allows the connecting portion 303 to connect to the insertion end 102 of the gastric tube body 1 in an inclined manner, thus forming a clamping gap 302 between the connecting portion 303 and the gastric tube body 1 capable of accommodating gastric tissue. The outer portion 304 is bowl-shaped, resembling an open bowl with an open end connected to the end of the connecting portion 303 opposite to the insertion end 102. This creates a movable cavity 301 between the outer portion 304 and the connecting portion 303, facilitating the introduction of the guide wire 2 and the clamping member 3.

[0083] The connecting portion 303 and the outer portion 304 are both made of flexible materials, such as polyurethane or silicone, which reduces patient discomfort when the connecting portion 303 and the outer portion 304 are inserted into the stomach. In addition, the flexible material connecting portion 303 and the outer portion 304 have a certain degree of plasticity and can undergo slight deformation as the guide wire 2 is lengthened and pulled. In other words, it can change the opening angle of the clamping gap to a certain extent.

[0084] Furthermore, the clamping component 3 also includes a hook 305, which, in conjunction with... Figures 9-11 As shown, the hook 305 is disposed at one end of the connecting part 303 away from the insertion end 102, and the tip of the hook 305 extends obliquely toward the bottom of the clamping gap 302. In this way, the external stomach tissue can enter into the clamping gap along the tip, and when the stomach tissue enters the clamping gap, it will be hooked by the hook 305, so that the stomach tissue cannot escape from the clamping gap.

[0085] In summary, the design of the hook 305 significantly enhances the clamping ability of the clamping component 3. The hook 305 is used to lock the stomach tissue, so that the stomach tissue can be firmly locked in the clamping gap.

[0086] Furthermore, the clamping component 3 also includes a fixing member 306; combined with Figure 11 As shown, the fixing member 306 includes a rotating shaft 307 and at least two rotating flaps 308 rotatably connected to the rotating shaft 307; the following detailed explanation uses two rotating flaps 308 as an example. The rotating shaft 307 is located at the connection between the connecting part 303 and the gastric tube body 1; one rotating flap 308 is connected to the connecting part 303, and the other rotating flap 308 is connected to the gastric tube body 1; the fixing member 306 can be understood as a hinge structure.

[0087] By setting the aforementioned fastener 306 and combining it with the guide wire 2, the connecting part 303 can rotate relative to the gastric tube body 1 via the rotating shaft 307, thereby changing the angle of the clamping gap; in addition, it can also keep the clamping gap at a certain fixed angle.

[0088] In summary, the fixture 306 makes the structure of the clamping member 3 more flexible. It not only allows the connecting part 303 to rotate relative to the gastric tube body 1, but also provides the necessary stability and controllability.

[0089] In this embodiment, combined with Figure 12 As shown, the connecting part includes a connector 309, a support rod 310, and a connecting rod 311. Specifically, the connector 309 surrounds one end of the insertion end and is angled relative to the gastric tube body 1, forming a clamping gap 302 between the connector 309 and the gastric tube body 1. Specifically, the support rods 310 are arranged at equal intervals along the circumferential direction of the gastric tube body 1 and are angled relative to the gastric tube body 1; the connecting rods 311 connect adjacent support rods; further, the connecting rod 311 includes a first segment 312 and a second segment 313 connected to each other, with the ends of the first segment 312 and the second segment 313 facing away from each other connected to the support rod 310. The ends of the first segment 312 and the second segment 313 close to each other are angled together.

[0090] Specifically, the guide wire 2 is connected to the support rod 310 via the fixing member 306 (the fixing member 306 means that the guide wire 2 extends towards the end of the connector 309 after winding around the rotating shaft 307, and is finally fixed to the end of the connector 309 by the fixing buckle); when the guide wire 2 is pulled outward, the support rod 310 moves towards the direction closer to the gastric tube body 1, reducing the size of the clamping gap 302; when the guide wire 2 is released inward, the size of the clamping gap 302 is increased, thereby adjusting the size of the clamping gap 302.

[0091] It is worth noting that the aforementioned support rod 310 and connecting rod 311 are made of plastic tubing.

[0092] In this embodiment, a multifunctional gastric tube further includes a locking member 4; the locking member 4 includes a fixing part 401 and a locking part 402, the fixing part 401 is disposed on the gastric tube body 1 at the position corresponding to the inlet end 101; the locking part 402 is sleeved on the part of the guide wire 2 that is exposed in the gastric tube body 1. In actual use, when the tissue to be clamped is clamped in the clamping gap 302, the guide wire 2 in this state needs to be locked onto the gastric tube body 1 to prevent the size of the clamping gap 302 from changing due to the change in the length of the guide wire 2, which could cause the gastric tissue to slip out of the clamping gap. At this time, the locking part 402 can be screwed onto the fixing part 401. When the locking part 402 is screwed onto the fixing part 401, the locking part 402 will close the fixing part 401. Since the guide wire 2 extends to the gastric tube body 1 through the fixing part 401, when the fixing part 401 is closed, the guide wire 2 can also be fixed onto the gastric tube body 1, thereby keeping the tissue to be clamped in a clamped state.

[0093] Specifically, Figures 1-3 The structure is shown with the locking member 4 in the open state, that is, the locking part 402 is not screwed onto the fixing part 401; that is, the process of clamping stomach tissue is underway at this time. Figure 6 and Figure 7 The structure is such that the locking member 4 is in the locked state, that is, the locking part 402 is screwed onto the fixing part 401; that is, the stomach tissue has been clamped and fixed.

[0094] Furthermore, combined Figure 3 and Figure 7As shown, the fixing part 401 includes multiple arc-shaped plates 403 with external threads arranged at intervals along the circumference. The arc-shaped plates 403 are evenly distributed in the circumferential direction, forming a converging and expanding conductive space through which the guide wire 2 can pass and enter the gastric tube body 1. The locking part 402 is a locking nut 404, which has an internal thread that matches the external thread. In actual use, the locking nut 404 can be screwed onto the outer wall of the multiple arc-shaped plates 403. As the locking nut 404 rotates, it gradually engages tightly with the external thread of the arc-shaped plates 403, thereby generating an inward squeezing force on the multiple arc-shaped plates 403, which in turn converges and clamps the guide wire 2 located between them, keeping the gastric tissue in a stable clamped state and preventing it from falling off due to external force or other factors.

[0095] In summary, the locking component 4 makes the multi-functional gastric tube more reliable and efficient in clamping and fixing tissues. It not only ensures the stability of gastric tissue in the clamped state but also improves the controllability and operational efficiency of the surgeon during surgery or examination.

[0096] In this embodiment, a multifunctional gastric tube also includes a guide tube 5, combined with... Figure 8 As shown, the guide tube 5 is attached to the inner wall of the gastric tube body 1 along the extension direction of the gastric tube body 1, and extends to the inner wall of the connecting part 303 until the end of the clamping member 3 near the inlet end 101; that is, the guide tube 5 is a tubular structure coaxial with the gastric tube body 1, and its length covers from the gastric tube body 1 to the end of the clamping member 3 near the inlet end 101. Specifically, the guide tube 5 provides a stable guiding channel for the guide wire 2 to be inserted and passed through.

[0097] In summary, the guide wire 2 can extend into the guide tube 5 and along the path of the guide tube 5 to the end of the clamping member 3 near the inlet end 101. This configuration ensures the stability and accuracy of the guide wire 2 during the insertion process and reduces deviations caused by external forces or other factors.

[0098] In this embodiment, multiple guide wires 2 and multiple guide tubes 5 are provided; the multiple guide wires 2 and multiple guide tubes 5 are arranged at intervals along the circumference of the gastric tube body 1, and the multiple guide wires 2 and multiple guide tubes 5 correspond one-to-one.

[0099] Furthermore, an operating handle 201 is provided at the end of the guide wire 2 exposed in the gastric tube body 1. In actual use, the guide wire 2 can be operated by operating the operating handle 201.

[0100] In summary, the simultaneous and coordinated operation of multiple guide wires 2 enables precise circumferential gripping of gastric tissue. Furthermore, each guide wire 2 has a corresponding guide tube 5, ensuring that each guide wire 2 can stably extend into the designated position of the gripping member 3 along its corresponding guide tube 5. In addition, the guide tube 5 prevents interference between the multiple guide wires 2.

[0101] In this embodiment, combined with Figure 1 As shown, the gastric tube body 1 has an operating end 103 located near the inlet end 101 and opposite the insertion end 102; a drainage hole 104 is provided at one end of the gastric tube body 1 near the insertion end 102, and a one-way valve is provided at the drainage hole 104. In actual use, when liquid is introduced into the gastric tube body 1 through the operating end 103, the one-way valve can achieve one-way drainage from the inside to the outside of the gastric tube body 1, preventing inward permeation, ensuring that gastric juice and esophageal mucus are confined within the esophagus and stomach during the esophageal bed pulling process, reducing the risk of esophageal bed contamination. This solves the existing technical problem that, in surgical applications, the presence of multiple drainage holes 104 can lead to the permeation of esophageal and gastric contents into the esophageal bed or around the anastomosis, requiring the use of large amounts of saline for irrigation during surgery, which still leaves significant hidden dangers for anastomosis healing and tubular stomach healing.

[0102] Example 2

[0103] This embodiment also provides a multifunctional gastric tube. It can achieve the same functionality as the first embodiment, as described below. Figure 13 and Figure 14 Detailed explanation. This multifunctional gastric tube includes a gastric tube body, a guide wire, and a clamping component; wherein the gastric tube body has an inlet end and an outlet end opposite to the inlet end. The definitions of the inlet end and the outlet end are the same as in Embodiment 1, so they will not be repeated here.

[0104] Specifically, the gripping member is mounted on the insertion end via a rotating component, allowing the gripping member to open or close at the insertion end. When the gripping member opens the insertion end, a clamping gap is formed between the gripping member and the insertion end. This rotating component is the same as the fixing component in Embodiment 1, enabling the gripping member to rotate relative to the gastric tube body, thereby allowing the gripping member to open or close at the insertion end. Further, the gripping member is a claw 8, with a hook on the claw facing the insertion end. The specific structure and function of the hook are the same as in Embodiment 1 and will not be described further.

[0105] Specifically, the guide wire extends into the main body of the gastric tube through the insertion end and passes through the main body of the gastric tube above the connection point between the insertion end and the clamping member, connecting to the end of the clamping member opposite to the insertion end. In actual use, first, the guide wire is loosened so that the clamping member fits against the insertion end; then it is inserted into the stomach; once it reaches the stomach, the guide wire is pulled outward so that the clamping member opens at the insertion end and hooks the tissue within the clamping gap; finally, once the tissue is hooked, the main body of the gastric tube is pulled outward.

[0106] Specifically, since part of the guidewire passes through the main body of the gastric tube, a corrugated tube is fitted at the point where the guidewire passes through the main body of the gastric tube; the corrugated tube 6 can contract or extend with the traction of the guidewire, that is, it can deform with the movement of the guidewire to adapt to the movement of the guidewire and ensure that the guidewire will not damage the stomach.

[0107] Specifically, multiple clamping components are provided, and these components are arranged at equal intervals along the circumferential sidewall of the gastric tube body. Optionally, three clamping components are provided. In addition, a groove 7 is provided on the side of the gripper away from the insertion end. The groove 7 is bound with a rubber elastic rope, which enables the clamping components to have a certain retraction force. When the guide wire 2 is released, the three clamping components will retract and fasten to the insertion end 102 under the action of the rubber elastic rope.

[0108] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
