Description

Technical Field

[0001] This invention relates to the field of gastric resection surgery technology, and in particular to a multifunctional gastric forceps. Background Technology

[0002] Gastric forceps are used to clamp the stumps of the stomach or colon. They have a multi-jointed axis, are powerful and have strong squeezing force, and prevent tissue from falling off.

[0003] The existing Chinese patent with publication number CN213129753U discloses a medical surgical tool, more specifically a medical gastric forceps, which can fix the biting state of the gastric forceps during use, thereby reducing the workload of doctors. A ladder positioning plate is connected to a rotating shaft, and a fastening screw I engages with the ladder positioning plate via threads. The rotating shaft is also connected to the device handle body I via threads. A fastening bolt I is connected to both the rotating shaft and the device handle body I. A semi-circular through groove is provided on the device handle body II. A shaped fixing component is connected to the device handle body I, and the fastening screw II engages with the shaped fixing component via threads. The shaped fixing component is adapted to the ladder positioning plate.

[0004] While this patent aims to fix the bite state of the gastric forceps and thus reduce the workload of doctors, its function is relatively simple, only fixing the bite state of the gastric forceps. During gastric resection surgery, there are many manual operations and a lot of instability. When using gastric forceps in gastric resection surgery, because the function of the gastric forceps is relatively simple, it cannot assist medical staff in performing clamping, cutting, pressing and hemostasis procedures. Further processing and improvement of the structure of the gastric forceps are required. Therefore, the inventor has proposed a multifunctional gastric forceps to solve the above-mentioned technical problem of the gastric forceps having a relatively simple function. Summary of the Invention

[0005] To overcome the shortcomings mentioned above, the invention aims to provide a technical solution that can solve the above problems.

[0006] A multifunctional gastric forceps includes an upper movable forceps and a lower movable forceps. One end of the upper movable forceps and the lower movable forceps is a forceps body, and one end of the forceps body is connected to a handle. The surfaces of the upper movable forceps and the lower movable forceps are provided with receiving cavities, which are concave in shape. The surfaces of the upper movable forceps and the lower movable forceps are provided with sliding grooves, which are connected to the receiving cavities.

[0007] The upper movable forceps have a slot for placing an external pinhole camera. The camera's image can assist medical staff in arranging the gastric resection surgery. The upper movable forceps also have a slot for placing an external power cord, which is connected to the slot. The lower movable forceps have a mounting slot with a heating element attached to its inner surface. The lower movable forceps also have a cable groove for placing the external power cord, which is connected to the mounting slot in a T-shape. The inner surface of the receiving cavity is equipped with an auxiliary device for clamping, cutting, compressing, or stopping bleeding of the gastric tissue during the gastric resection surgery. The inner surface of the receiving cavity also has a limit fixing hole.

[0008] Furthermore, the auxiliary device includes a clamping assembly, which includes a pad, a protective pad, and a limiting protrusion that is matched and installed with the limiting fixing hole. The limiting protrusion is arc-shaped and is symmetrically installed at both ends of the pad. The limiting protrusion and the limiting fixing hole are interlocked, thereby increasing the connection stability between the pad and the receiving cavity and reducing the probability of the pad falling out of the receiving cavity.

[0009] Furthermore, the pad and the receiving cavity are detachable structures, and the shape of the pad and the receiving cavity are consistent. The pad is T-shaped, and the top of the pad abuts against one end of the protective pad. The protective pad is used to clamp the gastric tissue. The protective pad is flush with the surface of the upper or lower movable forceps. When the protective pads of the upper and lower movable forceps face opposite directions and move inward at the same time, the protective pads prevent the pad from scratching the gastric tissue. When the upper and lower movable forceps apply force to the protective pads at the same time, the force causes the two opposing protective pads to form a clamping force to clamp the gastric tissue, making it easier for medical personnel to move the gastric tissue.

[0010] Furthermore, the auxiliary device includes a cutting assembly, which comprises a clamping block, a blade, and a spring block that is paired with a limiting and fixing hole. The spring block is arc-shaped and symmetrically installed at both ends of the clamping block. The clamping block and the receiving cavity are detachable and have the same shape. The clamping block is T-shaped, and the blade is installed on the top of the clamping block. The blade is used to cut gastric tissue, and the highest point of the blade is higher than the surface of the upper or lower movable forceps. The spring block and the limiting and fixing hole are mutually engaged, thereby increasing the connection stability between the clamping block and the receiving cavity and reducing the probability of the clamping block falling out of the receiving cavity. When the blades of the upper and lower movable forceps face opposite directions and move inward at the same time, the blades cut the gastric tissue. When the upper and lower movable forceps apply force to the blades at the same time, the force causes the two opposing blades to form scissors to cut the gastric tissue, making it easier for medical personnel to remove the gastric tissue.

[0011] Furthermore, the auxiliary device includes a clamping assembly, which includes a connecting block, a top block, and several clamping teeth mounted on the surface of the connecting block for gripping stomach tissue. The top block is arc-shaped and is used to mate with the limiting and fixing holes. The top block is symmetrically mounted at both ends of the connecting block. The clamping teeth are linearly arranged on the surface of the connecting block, with the distance between two adjacent clamping teeth being equidistant. The top block and the limiting and fixing holes engage with each other, thereby increasing the connection stability between the connecting block and the receiving cavity and reducing the probability of the connecting block falling out of the receiving cavity. When the clamping teeth of the upper and lower movable clamps face opposite directions and move inward simultaneously, the clamping teeth prevent the stomach tissue from being gripped. When the upper and lower movable clamps apply force to the clamping teeth simultaneously, the force causes the two opposing clamping teeth to form a clamping force to grip the stomach tissue, thus applying pressure to the stomach tissue and facilitating the medical personnel to clamp the stomach tissue.

[0012] Furthermore, the surface of the clamping tooth is provided with a buffer pad, which is used to buffer the force of the clamping tooth. The connecting block and the receiving cavity are detachable structures, and the shape of the connecting block and the receiving cavity are consistent. The connecting block is T-shaped, and the highest point of the clamping tooth is higher than the surface of the upper or lower movable clamp. The buffer pad is used to buffer the pressure exerted by the clamping tooth on the stomach tissue, so as to avoid the surface of the clamping tooth scratching the stomach tissue and causing bleeding.

[0013] Furthermore, the auxiliary device includes a hemostatic assembly, which includes a blood pressure block, a heat-conducting plate, and a locking block for mating and mounting with the limiting and fixing hole. The locking block is arc-shaped and symmetrically mounted at both ends of the blood pressure block. The blood pressure block and the receiving cavity are detachable structures. They are interlocked by the locking block and the limiting and fixing hole, thereby increasing the connection stability between the blood pressure block and the receiving cavity and reducing the probability of the blood pressure block falling out of the receiving cavity.

[0014] Furthermore, the shape of the blood pressure block is consistent with that of the receiving cavity. The blood pressure block is T-shaped, with one end of the heat-conducting plate abutting against the surface of the blood pressure block. The heat-conducting plate is located between the blood pressure block and the heating element. A heat-insulating pad for blocking temperature is installed on the surface of the blood pressure block. The highest point of the blood pressure block is higher than the surface of the upper or lower movable clamp. When the blood pressure blocks of the upper and lower movable clamps face opposite directions and move inward at the same time, the blood pressure block clamps the stomach tissue. When the heating element is powered on and generates heat, the heat generated by the heating element is transferred through the heat-conducting plate, thereby heating the blood pressure block. When the stomach tissue is heated, it produces a burning effect, thereby forming a scab at the site of stomach tissue resection, achieving the effect of hemostasis.

[0015] When the upper and lower movable clamps apply force to the blood pressure block simultaneously, the force causes the two opposing blood pressure blocks to clamp the stomach tissue, further accelerating the hemostasis of the stomach tissue. The heat insulation pad is used to assist medical personnel in removing the heated blood pressure block, preventing burns to the hands of medical personnel.

[0016] Furthermore, the upper movable clamp is provided with a connector and a mounting block at one end near the clamp body, and the lower movable clamp is provided with a limiting plate and a limiting wheel that are matched and installed with the connector and the mounting block at one end near the clamp body. The connector and the limiting plate and the mounting block and the limiting wheel are all connected by limiting screws. The connecting head and the limiting plate and the mounting block and the limiting wheel are connected by limiting screws, so that the upper movable clamp is in a cross shape near the clamp body, which makes it easier for medical personnel to grasp.

[0017] Furthermore, both the mating groove and the wire groove are connected to a power connection wire for connecting to an external power source. The upper and lower movable clamps are each provided with a wire hole for mounting the power connection wire at one end near the clamp body. One end of the power connection wire extends beyond the surface of the wire hole. The surface of the upper movable clamp is provided with a camera hole that communicates with the interior of the placement groove.

[0018] Furthermore, the surface of the handle is connected to an anti-slip pad, and the surface of the anti-slip pad is provided with a number of anti-slip protrusions to increase friction. The anti-slip protrusions are linearly arranged on the outer side of the anti-slip pad, and the distance between two adjacent anti-slip protrusions is equal. A limit block is connected to the outer side of the handle, and a spring piece is installed at the end of the handle away from the limit block to assist the upper and lower movable clamps in resetting. The spring piece is fixed to one end of the handle by a fixing screw.

[0019] Compared with the prior art, the beneficial effects of the present invention are: by using an auxiliary device to assist in the work of clamping, cutting, compressing or stopping bleeding of gastric tissue during gastrectomy, the gastric forceps can respectively have clamping effect, cutting effect, compressing effect and hemostasis effect, and the use of a replaceable method increases the functionality of the gastric forceps, achieving a multi-functional effect;

[0020] In addition, an external pinhole camera can be placed in the slot, and the images captured by the pinhole camera can assist medical staff in real-time monitoring of the gastric reduction surgery, making it easier for medical staff to arrange the gastric reduction surgery.

Detailed Implementation

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0038] Example 1:

[0039] For this embodiment, please refer to Figures 1-9 and Figure 10 The specific implementation of the multifunctional gastric forceps includes an upper movable forceps 1 and a lower movable forceps 2. One end of the upper movable forceps 1 and the lower movable forceps 2 is a forceps body 3. One end of the forceps body 3 is connected to a handle 4. The surfaces of the upper movable forceps 1 and the lower movable forceps 2 are provided with a receiving cavity 5. The receiving cavity 5 is concave in shape. The surfaces of the upper movable forceps 1 and the lower movable forceps 2 are provided with a sliding groove 6, which communicates with the receiving cavity 5.

[0040] The upper movable forceps 1 has a slot 7 for placing an external pinhole camera.

The inner surface of the receiving cavity 5 has a limit fixing hole 12.

[0041] The auxiliary device includes a clamping assembly, which includes a pad 13, a protective pad 14, and a limiting protrusion 15 that is matched and installed with the limiting fixing hole 12. The limiting protrusion 15 is arc-shaped and is symmetrically installed at both ends of the pad 13. The limiting protrusion 15 and the limiting fixing hole 12 are interlocked, thereby increasing the connection stability between the pad 13 and the receiving cavity 5 and reducing the probability of the pad 13 falling out of the receiving cavity 5.

[0042] The pad 13 and the receiving cavity 5 are detachable structures. The shape of the pad 13 and the receiving cavity 5 are consistent. The pad 13 is T-shaped. The top of the pad 13 abuts against one end of the protective pad 14. The protective pad 14 is used to clamp the stomach tissue. The protective pad 14 is flush with the surface of the upper movable forceps 1 or the lower movable forceps 2. When the protective pads 14 of the upper movable forceps 1 and the lower movable forceps 2 face opposite directions and move inward at the same time, the protective pad 14 prevents the pad 13 from scratching the stomach tissue. When the upper movable forceps 1 and the lower movable forceps 2 apply force to the protective pad 14 at the same time, the force makes the two protective pads 14 form a clamping force to clamp the stomach tissue, which facilitates the movement of the stomach tissue by medical personnel.

[0043] The upper movable clamp 1 is provided with a connector 26 and a mounting block 27 at one end near the clamp body 3. The lower movable clamp 2 is provided with a limiting plate 28 and a limiting wheel 29 that are paired with the connector 26 and the mounting block 27 at one end near the clamp body 3. The connector 26 and the limiting plate 28 and the mounting block 27 and the limiting wheel 29 are all connected by limiting screws 30. The connecting screws 30 connect the connector 26 and the limiting plate 28 and the mounting block 27 and the limiting wheel 29 respectively, so that the upper movable clamp 1 is in a cross shape near the clamp body 3, which makes it easier for medical personnel to grasp.

[0044] Both the mating groove 8 and the wire groove 11 are connected to a power connection wire 31 for connecting to an external power source. The upper movable clamp 1 and the lower movable clamp 2 are provided with a wire hole 32 at one end near the clamp body 3 to be installed with the power connection wire 31. One end of the power connection wire 31 extends beyond the surface of the wire hole 32. The surface of the upper movable clamp 1 is provided with a camera hole 33, which is in communication with the interior of the placement groove 7.

[0045] The surface of the handle 4 is connected to an anti-slip pad 34. The surface of the anti-slip pad 34 is provided with a plurality of anti-slip protrusions 35 for increasing friction. The anti-slip protrusions 35 are linearly arranged on the outer side of the anti-slip pad 34, and the distance between two adjacent anti-slip protrusions 35 is equal. The outer side of the handle 4 is connected to a limit block 36. A spring piece 37 for assisting the upper movable clamp 1 and the lower movable clamp 2 to reset is installed at the end of the handle 4 away from the limit block 36. The spring piece 37 is fixed to one end of the handle 4 by a fixing screw 38.

[0046] The key design feature of this embodiment is that the clamping effect of the gastric forceps is enhanced by using clamping components, and the functionality of the gastric forceps is increased by using a replaceable method, thus achieving a multi-functional effect.

[0047] Example 2:

[0048] Please refer to the figure for this embodiment.

One end of the upper movable forceps 1 and the lower movable forceps 2 is a forceps body 3. One end of the forceps body 3 is connected to a handle 4. The surfaces of the upper movable forceps 1 and the lower movable forceps 2 are provided with a receiving cavity 5. The receiving cavity 5 is concave in shape. The surfaces of the upper movable forceps 1 and the lower movable forceps 2 are provided with a sliding groove 6, which communicates with the receiving cavity 5.

The highest point of the blade 17 is higher than the surface of the upper movable clamp 1 or the lower movable clamp 2. The clamping block 16 and the limiting fixing hole 12 are interlocked, thereby increasing the connection stability between the clamping block 16 and the receiving cavity 5 and reducing the probability of the clamping block 16 falling out of the receiving cavity 5. When the blades 17 of the upper movable clamp 1 and the lower movable clamp 2 face opposite directions and move inward at the same time, the blades 17 play a role in cutting the stomach tissue. When the upper movable clamp 1 and the lower movable clamp 2 apply force to the blades 17 at the same time, the force makes the two opposing blades 17 form scissors to cut the stomach tissue, making it easier for medical personnel to remove the stomach tissue.

[0051] The upper movable clamp 1 is provided with a connector 26 and a mounting block 27 at one end near the clamp body 3. The lower movable clamp 2 is provided with a limiting plate 28 and a limiting wheel 29 that are paired with the connector 26 and the mounting block 27 at one end near the clamp body 3.

[0052] Both the mating groove 8 and the wire groove 11 are connected to a power connection wire 31 for connecting to an external power source. The upper movable clamp 1 and the lower movable clamp 2 are provided with a wire hole 32 at one end near the clamp body 3 to be installed with the power connection wire 31.

The surface of the upper movable clamp 1 is provided with a camera hole 33, which is in communication with the interior of the placement groove 7.

[0053] The surface of the handle 4 is connected to an anti-slip pad 34. The surface of the anti-slip pad 34 is provided with a plurality of anti-slip protrusions 35 for increasing friction. The anti-slip protrusions 35 are linearly arranged on the outer side of the anti-slip pad 34, and the distance between two adjacent anti-slip protrusions 35 is equal.

The spring piece 37 is fixed to one end of the handle 4 by a fixing screw 38.

[0054] The key design feature of this embodiment is that the cutting effect of the gastric forceps is enhanced by using a cutting component, and the functionality of the gastric forceps is increased by using a replaceable method, thus achieving a multi-functional effect.

[0055] Example 3:

[0056] Please refer to the figure for this embodiment. Figures 1-9 and Figure 12 The specific implementation of the multifunctional gastric forceps includes an upper movable forceps 1 and a lower movable forceps 2. One end of the upper movable forceps 1 and the lower movable forceps 2 is a forceps body 3. One end of the forceps body 3 is connected to a handle 4. The surfaces of the upper movable forceps 1 and the lower movable forceps 2 are provided with a receiving cavity 5. The receiving cavity 5 is concave in shape. The surfaces of the upper movable forceps 1 and the lower movable forceps 2 are provided with a sliding groove 6, which communicates with the receiving cavity 5.

[0057] The upper movable forceps 1 has a slot 7 for placing an external pinhole camera. The pinhole camera can be placed in the slot 7 to assist medical staff in arranging the gastric resection surgery.

The locking teeth 21 are linearly arranged on the surface of the connecting block 19, with equidistant spacing between adjacent locking teeth 21. The top block 20 engages with the limiting and fixing holes 12, thereby increasing the clamping force between the connecting block 19 and the stomach tissue. The connection stability of the receiving cavity 5 reduces the probability of the connecting block 19 falling out of the receiving cavity 5. When the jaws 21 of the upper movable clamp 1 and the lower movable clamp 2 face opposite directions and move inward at the same time, the jaws 21 prevent the stomach tissue from being gripped. When the upper movable clamp 1 and the lower movable clamp 2 apply force to the jaws 21 at the same time, the force causes the two opposing jaws 21 to form a clamping force to grip the stomach tissue, so that the jaws 21 apply pressure to the stomach tissue, making it easier for medical personnel to compress the stomach tissue.

[0059] The surface of the locking tooth 21 is provided with a buffer pad 22, which is used to buffer the force of the locking tooth 21. The connecting block 19 and the receiving cavity 5 are detachable structures. The connecting block 19 and the receiving cavity 5 have the same shape. The connecting block 19 is T-shaped. The highest point of the locking tooth 21 is higher than the surface of the upper movable clamp 1 or the lower movable clamp 2. The buffer pad 22 is used to buffer the pressure exerted by the locking tooth 21 on the stomach tissue and avoid the surface of the locking tooth 21 scratching the stomach tissue, thereby causing bleeding.

[0060] The upper movable clamp 1 is provided with a connector 26 and a mounting block 27 at one end near the clamp body 3. The lower movable clamp 2 is provided with a limiting plate 28 and a limiting wheel 29 that are paired with the connector 26 and the mounting block 27 at one end near the clamp body 3. The connector 26 and the limiting plate 28 and the mounting block 27 and the limiting wheel 29 are all connected by limiting screws 30. The connecting screws 30 connect the connector 26 and the limiting plate 28 and the mounting block 27 and the limiting wheel 29 respectively, so that the upper movable clamp 1 is in a cross shape near the clamp body 3, which makes it easier for medical personnel to grasp.

[0061] Both the mating groove 8 and the wire groove 11 are connected to a power connection wire 31 for connecting to an external power source. The upper movable clamp 1 and the lower movable clamp 2 are provided with a wire hole 32 at one end near the clamp body 3 to be installed with the power connection wire 31. One end of the power connection wire 31 extends beyond the surface of the wire hole 32. The surface of the upper movable clamp 1 is provided with a camera hole 33, which is in communication with the interior of the placement groove 7.

[0062] The surface of the handle 4 is connected to an anti-slip pad 34. The surface of the anti-slip pad 34 is provided with a plurality of anti-slip protrusions 35 for increasing friction. The anti-slip protrusions 35 are linearly arranged on the outer side of the anti-slip pad 34, and the distance between two adjacent anti-slip protrusions 35 is equal. The outer side of the handle 4 is connected to a limit block 36. A spring piece 37 for assisting the upper movable clamp 1 and the lower movable clamp 2 to reset is installed at the end of the handle 4 away from the limit block 36. The spring piece 37 is fixed to one end of the handle 4 by a fixing screw 38.

[0063] The key design feature of this embodiment is that the clamping effect of the gastric forceps is increased by using a clamping component, and the functionality of the gastric forceps is increased by using a replaceable method, thus achieving a multi-functional effect.

The inner surface of the receiving cavity 5 is equipped with an auxiliary device for clamping, cutting, compressing or stopping bleeding of the gastric tissue during the gastric resection surgery. The inner surface of the receiving cavity 5 has a limit fixing hole 12.

[0067] The auxiliary device includes a hemostatic assembly, which includes a blood pressure block 22, a heat-conducting plate 23, and a locking block 24 for mating with the limiting and fixing hole 12. The locking block 24 is arc-shaped and is symmetrically installed at both ends of the blood pressure block 22. The blood pressure block 22 and the receiving cavity 5 are detachable. The locking block 24 and the limiting and fixing hole 12 are interlocked, thereby increasing the connection stability between the blood pressure block 22 and the receiving cavity 5 and reducing the probability of the blood pressure block 22 falling out of the receiving cavity 5.

[0068] The blood pressure-stopping block 22 is T-shaped and has one end of the heat-conducting plate 23 in contact with the surface of the blood pressure-stopping block 22. The heat-conducting plate 23 is located between the blood pressure-stopping block 22 and the heating plate 10. The surface of the blood pressure-stopping block 22 is equipped with a heat-insulating pad 25 for blocking temperature. The highest point of the blood pressure-stopping block 22 is higher than the surface of the upper movable clamp 1 or the lower movable clamp 2. When the blood pressure-stopping blocks 22 of the upper movable clamp 1 and the lower movable clamp 2 face each other and move inward at the same time, the blood pressure-stopping block 22 can clamp the stomach tissue. When the heating plate 10 is powered on and generates heat, the heat generated by the heating plate 10 is transferred through the heat-conducting plate 23, so that the blood pressure-stopping block 22 is heated and has heat. When the stomach tissue is heated, it produces a burning effect, so that the excised site of the stomach tissue forms a scab, achieving the effect of hemostasis.

[0069] When the upper movable clamp 1 and the lower movable clamp 2 apply force to the blood pressure block 22 at the same time, the force causes the two blood pressure blocks 22 to form a clamping force to clamp the stomach tissue, further accelerating the hemostasis speed of the stomach tissue. The heat insulation pad 25 is used to assist medical personnel in removing the blood pressure block 22 after it has been heated, and plays a role in preventing burns to the hands of medical personnel.

[0070] The upper movable clamp 1 is provided with a connector 26 and a mounting block 27 at one end near the clamp body 3. The lower movable clamp 2 is provided with a limiting plate 28 and a limiting wheel 29 that are paired with the connector 26 and the mounting block 27 at one end near the clamp body 3. The connector 26 and the limiting plate 28 and the mounting block 27 and the limiting wheel 29 are all connected by limiting screws 30. The connecting screws 30 connect the connector 26 and the limiting plate 28 and the mounting block 27 and the limiting wheel 29 respectively, so that the upper movable clamp 1 is in a cross shape near the clamp body 3, which makes it easier for medical personnel to grasp.

[0071] Both the mating groove 8 and the wire groove 11 are connected to a power connection wire 31 for connecting to an external power source. The upper movable clamp 1 and the lower movable clamp 2 are provided with a wire hole 32 at one end near the clamp body 3 to be installed with the power connection wire 31. One end of the power connection wire 31 extends beyond the surface of the wire hole 32. The surface of the upper movable clamp 1 is provided with a camera hole 33, which is in communication with the interior of the placement groove 7.

[0072] The surface of the handle 4 is connected to an anti-slip pad 34. The surface of the anti-slip pad 34 is provided with a plurality of anti-slip protrusions 35 for increasing friction. The anti-slip protrusions 35 are linearly arranged on the outer side of the anti-slip pad 34, and the distance between two adjacent anti-slip protrusions 35 is equal. The outer side of the handle 4 is connected to a limit block 36. A spring piece 37 for assisting the upper movable clamp 1 and the lower movable clamp 2 to reset is installed at the end of the handle 4 away from the limit block 36. The spring piece 37 is fixed to one end of the handle 4 by a fixing screw 38.

[0073] The key design feature of this embodiment is that the hemostatic effect of the gastric forceps is enhanced by using hemostatic components, and the functionality of the gastric forceps is increased by using a replaceable method, thus achieving a multi-functional effect.
