Description

Technical Field

[0001] The present application specifically discloses a laparoscopic inflatable flexible grasping and suction device. Background Art

[0002] Currently, the operating instruments under laparoscope are all metal instruments. For example, in the design of a conventional non-traumatic grasping forceps, although the forceps tip is blunt, when grasping brittle tissues such as the mesentery, it may still cause tissue damage, and even the forceps tip may penetrate into the tissue, causing injury or bleeding.

[0003] In some surgeries, many domestic experts often use instruments such as intestinal forceps to grasp a single piece of gauze, or a gauze piece, or a sponge mass for exposure. On the one hand, it can better protect tissues and reduce injuries. On the other hand, it can suck away bloody exudates and keep the surgical field clean.

[0004] However, there are still many drawbacks in this method. For example, if the gauze is too large in volume, although it can achieve a good suction effect, it is inconvenient to use, and even more difficult to expose the surgical field. If the gauze is too small in volume, once it enters the abdominal cavity and is covered by abdominal organs, it is difficult to find, leaving a hidden danger. Summary of the Invention

[0007] According to the technical solution provided by the embodiment of the present application, it further includes: a suction tube provided in the tubular protection section and the suction tube extends along the axial direction of the working arm; one end of the suction tube close to the air inlet penetrates through the tubular protection section and is hermetically connected thereto; and, the other end of it penetrates through the tubular protection section or the forceps clip protection section and is hermetically connected thereto correspondingly.

[0008] According to the technical solution provided by the embodiment of the present application, the clamp protection section has a grid-like structure and all the grids are interconnected.

[0009] According to the technical solution provided by the embodiment of the present application, there are at least two suction tubes, and one side of the suction tube near the clamp head end is exposed outside the clamp protection section from the grid of the clamp protection section.

[0010] According to the technical solution provided by the embodiment of the present application, the suction tube includes: a first suction tube and a second suction tube; the length of the first suction tube is greater than the length of the second suction tube; the free end of the first suction tube is exposed outside the grid of the clamp protection section and the free end of the second suction tube is exposed in the middle of the tubular protection section.

[0011] According to the technical solution provided by the embodiment of the present application, a flexible protrusion is provided on the outer wall of the clamp protection section.

[0012] According to the technical solution provided by the embodiment of the present application, the protrusion includes: a first protrusion communicating with the inside of the clamp protection section and a second protrusion not communicating with the inside of the clamp protection section; the free end of the first protrusion is open and the suction tube can enter the first protrusion and be sealedly connected to its inner wall.

[0013] According to the technical solution provided by the embodiment of the present application, the free end of the suction tube exposed outside the first protrusion bends towards the side close to the protection layer and is circumferentially connected to the outer wall of the first protrusion.

[0014] According to the technical solution provided by the embodiment of the present application, a blocking and adjusting structure is provided on the inner wall of the suction tube entering the first protrusion; the blocking and adjusting structure includes: adjusting pieces arranged at intervals in a ring shape and in a wedge shape, and the adjusting pieces extend along the axial direction of the suction tube.

[0015] According to the technical solution provided by the embodiment of the present application, the adjusting piece includes: a pointed end portion and a blunt end portion with a height higher than that of the pointed end portion; the pointed end portions and the blunt end portions of two adjacent adjusting pieces face in opposite directions.

[0016] In summary, the present application discloses a laparoscopic inflatable flexible grasping and suction device. Based on the structure of the intestinal clamp body, the present technical solution adds a design of an internal hollow protective layer and designs the protection to include: a clamp protection section for protecting the clamp and a tubular protection section that is an integral structure with the clamp protection section and is sleeved on the outside of the working arm.

The sealed connection with the side wall of the tubular protection section or the clamp protection section can ensure that the sealing environment of the protective layer itself is not affected. In addition, in view of the design of the suction line, when it is exposed outside the tubular protection section and connected to a negative pressure device at the end away from the clamp head end, it can attract tissue fluid around the intestinal clamp body to expose the surgical field to a greater extent, so as to provide a better use environment for the intestinal clamp. In addition, the layout of the suction line is further optimized in the present application.

[0018] Other technical solutions in the present application further optimize the above-mentioned technical solutions by adding a protrusion outside the clamp protection section. When the clamp protection section is propped up as a whole, the protrusion can play a preliminary fixing role. In addition, the structure of the protrusion is further optimized and combined with the design of the suction tube, making the technical solutions in the present application more practical.

[0032] The following further elaborates on the present application in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are merely for explaining the relevant invention and not for limiting the invention. Additionally, it should be noted that for ease of description, only the parts related to the invention are shown in the drawings.

[0033] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will elaborate on the present application in detail with reference to the drawings and embodiments.

[0034] Please refer to Figure 1a and 1b Shown is an embodiment of an inflatable flexible grasping and suction device under endoscope.

[0035] A laparoscopic inflatable flexible grasping and suction device, comprising: an intestinal forceps body 10, the intestinal forceps body 10 comprising: a clamp head end 11 composed of at least two clamps and a working arm 12 for controlling the opening and closing of the clamp head end 11. The structure description and usage method of the intestinal forceps body have been described in the prior art and will not be elaborated here.

[0036] A protective layer 20 is commonly coated on the outer walls of the clamp head end 11 and the working arm 12; the protective layer 20 comprises: a flexible clamp protection section 21 fixed to the corresponding clamp along the side wall edges of the two clamps away from each other and a tubular protection section 22 of an integral structure with the clamp protection section 21 and sleeved outside the working arm 12; one end of the tubular protection section 22 far from the clamp head end 11 is sealed and fixed to the side wall of the working arm 12.

[0037] Specifically, the clamp protection section can be of a single-layer structure and hollow inside. When inflated, it forms a cystic structure, which can protect the clamp and can protect the tissue as much as possible to avoid tissue damage. Based on this design, the clamp protection section 21 is fixed to the corresponding clamp along the side wall edges of the two clamps away from each other, which can achieve the covering of the two clamps. When grasping the tissue, the presence of the protective layer can effectively prevent the clamp end from penetrating into the tissue, causing damage or bleeding.

[0038] Specifically, the tubular protection section is made of a rigid material relative to the clamp protection section, does not deform due to gas filling, and its outer wall material is wear-resistant and damage-resistant. Its side wall is hollow and the side wall of the protective layer 20 is hollow and the clamp protection section 21 is communicated with the tubular protection section 22.

[0039] Based on the above design, the inside of the protective layer forms an airtight environment as a whole, which is convenient for the gas to be filled and smoothly transmitted to the clamp protection section. An air inlet is provided at one end of the tubular protection section 22 far from the clamp head end 11. By filling and discharging gas from the air inlet through the tubular protection section 22 to the clamp protection section 21, the volume of the clamp protection section 21 can be adjusted.

[0040] Figure 1a In, the flexible protective layer is in an uninflated state; Figure 1b In, the flexible protective layer is in an inflated state.

[0041] In the prior art, in the design of a conventional non-invasive grasping forceps, although the clamp end is blunt, when grasping brittle tissues such as the mesentery, it is still possible to cause tissue damage, and even the clamp end penetrates into the tissue, causing damage or bleeding.

[0042] When gas is injected into the inlet on the tubular protection section, the gas will gradually enter the flexible clamp protection section along the tubular protection section, causing the overall volume of the clamp protection section to gradually increase from small to large, enabling flexible protection of the clamp. In addition, the gas-filled clamp protection section can block the restriction of intra-abdominal tissues on the use of the intestinal forceps, maximizing the exposure of the surgical field. When the use is completed, the gas in the protection layer can be discharged, and it can be conveniently taken out from the laparoscopic access hole.

[0043] Please refer to Figure 2a and 2b an embodiment of a laparoscopic gas-filled flexible grasping and suction device shown.

[0044] Figure 2a and Figure 2b a laparoscopic gas-filled flexible grasping and suction device shown in, further comprising: a suction tube 30 disposed within the tubular protection section 22 and the suction tube 30 extending axially along the working arm 12; one end of the suction tube 30 near the air inlet penetrates through the tubular protection section 22 and is sealingly connected thereto; and, the other end thereof away from the air inlet penetrates through the tubular protection section 22 or the clamp protection section 21 and is sealingly connected thereto correspondingly.

[0045] Wherein:

[0046] Figure 2a as shown in, no gas is filled in the protection layer.

[0047] Figure 2b as shown in, gas is filled in the protection layer.

[0048] In the design of adding a suction tube within the tubular protection section, the suction tube extends axially along the working arm. One end of the suction tube near the air inlet penetrates through the tubular protection section and is sealingly connected thereto; and, the other end thereof away from the air inlet penetrates through the tubular protection section or the clamp protection section and is sealingly connected thereto correspondingly. In this design, the relatively far end of the suction tube from the air inlet can either penetrate through the tubular protection section or the clamp protection section. Whether it penetrates through the tubular protection section or the clamp protection section, the relatively far end of the suction tube from the air inlet needs to be sealingly connected to the part it penetrates through.

[0049] Sealing connection with the side wall of the tubular protection section or the clamp protection section can ensure that the sealing environment of the protection layer itself is not affected. In addition, due to the design of the suction pipeline, when the end exposed outside the tubular protection section and away from the clamp head end is connected to a negative pressure device, it can suck the tissue fluid around the intestinal forceps body, maximizing the exposure of the surgical field and providing a better use environment for the intestinal forceps.

[0050] Please refer to Figure 3 an embodiment of a laparoscopic gas-filled flexible grasping and suction device shown.

[0051] Figure 3 In the structure shown, the clamp protection section 21 has a grid-like structure and all the grids are interconnected.

[0052] Based on this design, the grid-like design of the clamp protection section 21 makes the surface of the clamp protection section 21 uneven in height, which is likely to increase the friction force.

[0053] Please refer to Figure 4 an implementation manner of an endoscopic pneumatic flexible grasping and suction device shown.

[0054] There are at least two suction tubes 30, and one side of the suction tube 30 close to the clamp head end 11 is exposed outside the clamp protection section 21 from the grids of the clamp protection section 21.

[0055] Figure 4 In the provided design, the present implementation manner optimizes the setting of the suction tubes. When the number of suction tubes increases within the allowable range of the tubular protection section, it can improve the suction efficiency to a certain extent. In addition, when one side of the suction tube 30 close to the clamp head end 11 is exposed outside the clamp protection section 21 from the grids of the clamp protection section 21, it can avoid damage to the intra-abdominal tissues caused by the end of the suction tube, and the grids can provide a certain hiding effect.

[0056] Furthermore, please refer to Figure 5 , the number of suction tubes can preferably be designed as two.

[0057] The suction tube 30 includes: a first suction tube 31 and a second suction tube 32; the length of the first suction tube 31 is greater than the length of the second suction tube 32; the free end of the first suction tube 31 is exposed outside the grids of the clamp protection section 21 and the free end of the second suction tube 32 is exposed in the middle of the tubular protection section 22.

[0058] Based on the above design, in view of the existence of the first suction tube and the second suction tube, a hierarchical design of tissue fluid suction can be realized, which is convenient for quickly sucking tissue fluid and improving the efficiency. In addition, once any one of the suction tubes is blocked, the remaining suction tubes can still function.

[0059] Optionally, when the number of the suction tubes is three, four, or five, the free ends of the suction tubes are distributed in a stepped manner along the axial direction of the working arm.

[0060] Please refer to Figure 6 an implementation manner of an endoscopic pneumatic flexible grasping and suction device shown.

[0061] A flexible protrusion 23 is provided on the outer wall of the clamp protection section 21.

[0062] Figure 6 The design of the middle protrusion can clamp and protect the uneven surface height of the protection section 21, which is likely to increase the friction force.

[0063] Preferably, please refer to Figure 7 , in Figure 7 the middle protrusion includes two structures, namely:

[0064] The protrusion 23 includes: a first protrusion 231 that communicates with the inside of the clamping protection section 21 and a second protrusion 232 that does not communicate with the inside of the clamping protection section 21; the free end of the first protrusion 231 is open and the suction tube 30 can enter the first protrusion 231 and be hermetically connected to its inner wall.

[0065] Based on Figure 7 the specific design in, the existence of the first protrusion can be connected to the suction tube, realizing the hidden design of the suction tube, which can avoid damage to the intra-abdominal tissues caused by the end of the suction tube, and further optimize the overall design inside and outside the protection layer.

[0066] The design of the second protrusion can provide a certain supporting force for clamping.

[0067] On the basis of the above specific implementation manner, the free end of the suction tube 30 exposed outside the first protrusion 231 bends towards the side close to the protection layer 20 and is annularly connected to the outer wall of the first protrusion 231. Based on this design, the connection relationship between the first protrusion and the suction tube can enhance the sealing performance between the two and prevent gas leakage.

[0068] Please refer to Figure 8a and Figure 8b shown in an embodiment of the end face structure of the suction tube in a laparoscopic inflatable flexible grasping and suction device.

[0069] The inner wall of the suction tube 30 entering the outside of the first protrusion 231 is provided with a blocking and adjusting structure; the blocking and adjusting structure includes: adjusting pieces 40 that are arranged at intervals in a ring shape and are wedge-shaped, and the adjusting pieces 40 extend along the axial direction of the suction tube 30.

[0070] The inner wall of the suction tube 30 entering the outside of the first protrusion is provided with a blocking and adjusting structure; the blocking and adjusting structure includes: adjusting pieces 40 that are arranged at intervals in a ring shape and are wedge-shaped, and the adjusting pieces 40 extend along the axial direction of the suction tube 30.

[0071] In view of the fact that there may be some tissue debris remaining in the tissue fluid, it is very easy to enter the suction tube under the action of the negative pressure device, causing the suction pipeline to fail, thereby reducing the suction efficiency of the suction tube.

[0072] Figure 8aThe specific design in it can utilize the design of the adjusting piece in the blocking adjustment structure to relieve the above situation. The specific principle is as follows:

[0073] The adjusting pieces are arranged at annular intervals, which can play a preliminary blocking role to prevent too large tissues from entering the suction tube.

[0074] Even if some smaller tissues are hung between the adjusting pieces, under the action of the negative pressure device, the free end of the suction tube will generate rhythmic vibrations. Under the vibration force, the smaller tissues will come into contact with the adjusting pieces. The smaller tissues can be divided by the adjusting pieces under the action of the negative pressure device and will not block the suction tube even if they enter the suction tube.

[0075] Preferably, the adjusting piece 40 includes: a pointed end portion 41 and a blunt end portion 42 with a height higher than that of the pointed end portion 41; the pointed end portions 41 and the blunt end portions 42 of two adjacent adjusting pieces 40 face in opposite directions. That is: taking any adjusting piece as an example, when its pointed end portion faces the inside of the suction tube, the pointed end portion of the adjacent adjusting piece faces the outside of the suction tube.

[0076] Based on this design, the heights of the adjusting pieces in the blocking adjustment structure are different at the edge of the free end of the suction tube, and a better screening effect can be achieved; larger tissues cannot enter, and smaller tissues can pass through smoothly without blocking the suction tube at the free end of the suction tube.

[0077] More preferably, Figure 8c in the specific design, the adjusting piece includes: a pointed end portion 41 and a blunt end portion 42 with a height higher than that of the pointed end portion 41; a groove-shaped transition portion 43 is provided between the pointed end portion 41 and the blunt end portion 42, and a receiving space can be formed on the free edge of the adjusting piece centered on the transition portion to further prevent blockage.

[0078] The above description is only the preferred embodiments of the present application and the description of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
