Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a forceps-type minimally invasive electrode clamp. Background Technology

[0002] Minimally invasive surgical techniques generally reduce the amount of damage to extraneous tissues during surgical procedures, thereby reducing patient recovery time, discomfort, and harmful side effects. Minimally invasive surgery can effectively reduce postoperative hospital recovery time. Because the average hospital stay for standard surgery is typically significantly longer than that for similar minimally invasive surgeries, the increased use of minimally invasive techniques can save millions of dollars in hospital costs annually. Patient recovery time, patient discomfort, surgical side effects, and time away from work can also be reduced by increasing the use of minimally invasive surgery.

[0016] The two ends of the pull line are fixedly connected to the pull rod and pass through the first clamp and the second clamp to form a Y-shaped structure; as the pull rod is driven away from the clamp head assembly, the pull line is taut and drives the first clamp and the second clamp to move towards each other, driving the clamp head assembly to perform the clamping action.

The forceps-type minimally invasive electrode forceps according to claim 7, wherein the gripping handle is hinged to the outer shell on the side near the forceps head assembly; the hinge position of the gripping handle and the rotating link is located on the side away from the forceps head assembly.

[0027] The technical solution of the present invention has the following advantages:

[0028] 1. The forceps-type minimally invasive electrode forceps provided by the present invention includes:

[0029] The clamping head assembly includes: a first clamping tweezer and a second clamping tweezer, which are respectively provided as conductive components and connected to one of the positive and negative terminals of the circuit to enable the clamping head assembly to be energized.

[0030] The clamping assembly includes: a first clamping piece and a second clamping piece hinged together; a first clamping tweezer head is disposed at the end of the first clamping piece, and a second clamping tweezer head is disposed at the end of the second clamping piece; a circuit is electrically connected to the first clamping tweezer head and the second clamping tweezer head through the first clamping piece and the second clamping piece, respectively.

[0031] The clamping drive assembly is connected to the clamping assembly in a transmission manner, driving the first clamping plate and the second clamping plate to move towards each other and away from each other, so as to realize the clamping and opening action of the clamping head assembly.

[0032] In this invention, by respectively arranging the first and second clamping forceps on the first and second clamping plates of the clamping plate assembly, the clamping action of the electrode forceps is achieved through a forceps-like structure, effectively reducing the size of the minimally invasive electrode forceps and making it suitable for minimally invasive surgery. Furthermore, the first and second clamping forceps are conductive components, with the positive and negative terminals of the circuit supplying power to the first and second clamping forceps through the first and second clamping plates, respectively, effectively powering the forceps assembly.

[0033] 2. The forceps-type minimally invasive electrode forceps provided by the present invention further includes: a cooling assembly, comprising: a medium inlet pipe, a medium outlet pipe, and a heat exchange component; the medium inlet pipe and the medium outlet pipe are for the passage of cooling medium; the heat exchange component is used to cool the medium in the medium outlet pipe;

[0034] The first clamping tweezers head is provided with a corresponding medium inlet tube and a medium outlet tube, which are mounted on the first clamping plate; and the first clamping tweezers head is also provided with a through hole extending through its width direction, through which the medium inlet tube and the medium outlet tube are connected to each other to cool the first clamping tweezers head.

[0035] The second clamping tweezers head is provided with a corresponding medium inlet tube and a medium outlet tube, which are mounted on the second clamping plate; and the second clamping tweezers head is also provided with a through hole extending through its width direction, through which the medium inlet tube and the medium outlet tube are connected to each other, thereby cooling the second clamping tweezers head.

[0036] In this invention, by installing and fixing a media inlet and outlet pipe on the clamping plate, and then connecting these media inlet and outlet pipes to the clamping forceps position, the clamping forceps can be effectively cooled by the cooling medium within the pipes. This structure not only effectively cools the minimally invasive electrode forceps but also has the advantages of small size and stable, reliable structure. Furthermore, to ensure the cooling effect, a connecting hole for the cooling medium to pass through is provided in the width direction of the clamping forceps, allowing the cooling medium to fully contact the clamping forceps and ensuring the cooling capacity of the cooling component.

[0037] 3. The forceps-type minimally invasive electrode forceps provided by the present invention have arc-shaped positioning grooves on both sides of the first clamping forceps head in the width direction for positioning the medium inlet tube and the medium outlet tube, respectively; the connecting hole passes through the two oppositely arranged arc-shaped positioning grooves; the tube walls of the medium inlet tube and the medium outlet tube are provided with openings that communicate with the connecting hole;

[0039] In this invention, arc-shaped positioning grooves for positioning the medium inlet and outlet pipes are respectively provided on both sides of the clamping tweezers in the width direction. These arc-shaped positioning grooves effectively fix the medium inlet and outlet pipes to both sides of the clamping tweezers, allowing the cooling medium in the pipes to pass through the connecting holes of the clamping tweezers, thus ensuring the stable and reliable operation of the cooling assembly in this invention.

[0040] 4. The forceps-type minimally invasive electrode forceps provided by the present invention, wherein the clamp driving assembly includes: a traction wire, a traction rod fixedly connected to the traction wire, and a driving handle assembly for driving the extension and retraction of the traction rod;

[0041] The first clamp and the second clamp are provided with a pulling hole for the pulling line to pass through, and the first clamp and the second clamp are also provided with a guide pulley for guiding the pulling line;

[0042] The two ends of the pull line are fixedly connected to the pull rod and pass through the first clamp and the second clamp to form a Y-shaped structure; as the pull rod is driven away from the clamp head assembly, the pull line is taut and drives the first clamp and the second clamp to move towards each other, driving the clamp head assembly to perform the clamping action.

[0043] In this invention, the pull rod is extended or retracted by the drive handle assembly, which in turn tightens or loosens the pull line, thereby achieving the clamping and opening of the clamping head assembly. Furthermore, the first and second clamping plates are equipped with guide pulleys, which effectively guide the pull line to slide stably and reliably. In this invention, as the pull rod is driven away from the clamping head assembly, the pull line tightens, causing the first and second clamping plates to move towards each other, driving the clamping head assembly to perform the clamping action.

[0044] 5. The forceps-type minimally invasive electrode forceps provided by the present invention further includes:

[0045] A connecting sleeve is provided, and the first clamp and the second clamp are fixed on the connecting sleeve to limit and fix them; and the first clamp and the second clamp are elastic members, so that the clamp head assembly remains in the open state when the clamp driving assembly does not apply a force toward the clamp assembly;

[0046] As the pull rod is driven to approach the clamp head assembly, the pull line relaxes and releases the driving force on the first and second clamps, and the clamp head assembly returns to the open state under its own elasticity.

[0047] In this invention, the connecting sleeve effectively secures the first and second clamping pieces together. Simultaneously, the positional restriction of the connecting sleeve allows the first and second clamping pieces to remain open without being subjected to tension from the pull line, thereby enabling the clamping head assembly to automatically open via the elasticity of the first and second clamping pieces.

[0048] 6. The forceps-type minimally invasive electrode forceps provided by the present invention includes a drive handle assembly comprising:

[0049] The grip handle is hinged to the outer shell of the forceps-type minimally invasive electrode forceps and is connected to the traction rod via a rotating link. The rotating link is an arc-shaped component with both ends hinged to the grip handle and the traction rod, respectively. The grip handle drives the traction rod away from the forceps head assembly via the rotating link, tightens it through the traction line, and drives the first clamp and the second clamp to move towards each other, thereby driving the forceps head assembly to perform the clamping action.

[0050] An elastic element, connected in conjunction with the pull rod, compresses the elastic element to deform and store energy when the jaw assembly performs a clamping action; when the grip handle releases the driving force, the elastic element drives the pull rod to move toward the jaw assembly, and the pull line relaxes to open the jaw assembly.

[0051] In this invention, the aforementioned rotating linkage allows the grip handle to reliably drive the extension and retraction of the traction rod. Furthermore, when the grip handle releases its driving force, the aforementioned elastic element effectively drives the traction rod towards the jaw assembly, thereby relaxing the traction line and opening the jaw assembly.

[0052] 7. The forceps-type minimally invasive electrode forceps provided by the present invention further includes a first limiting support on the outer shell for limiting and fixing the connecting sleeve; and a second limiting support on the outer shell for limiting and fixing the traction rod.

[0053] In this invention, the first limiting support effectively limits and fixes the connecting sleeve, ensuring the stable and reliable operation of the medium inlet pipe, medium outlet pipe, and pull line within the connecting sleeve. Furthermore, the second limiting support effectively limits the pull rod, ensuring its stable and reliable extension and retraction. Attached Figure Description

[0066] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0067] Example 1

[0068] See Figure 6 and Figure 1 , Figure 6 A schematic diagram of the three-dimensional structure of the tweezer-type minimally invasive electrode forceps in an embodiment of the present invention is shown. Figure 1 A schematic diagram of the forceps-type minimally invasive electrode forceps structure in an embodiment of the present invention is shown.

[0069] This embodiment provides a tweezer-type minimally invasive electrode clamp, comprising:

[0070] Clamping head assembly, such as Figure 1 As shown, it includes: a first clamping tweezer 1 and a second clamping tweezer 2 respectively. The first clamping tweezer 1 and the second clamping tweezer 2 are conductive components and are respectively connected to one of the positive and negative terminals of the circuit to realize the tweezer assembly is energized.

[0071] Clip assemblies, such as Figure 1 As shown, it includes: a first clamping piece 3 and a second clamping piece 4 that are hinged together; the first clamping tweezers 1 is disposed at the end of the first clamping piece 3, and the second clamping tweezers 2 is disposed at the end of the second clamping piece 4; the circuit is electrically connected to the first clamping tweezers 1 and the second clamping tweezers 2 through the first clamping piece 3 and the second clamping piece 4, respectively.

[0072] The clamping drive assembly 5 is connected to the clamping assembly in a transmission manner, driving the first clamping plate 3 and the second clamping plate 4 to move towards each other and away from each other, so as to realize the clamping and opening action of the pliers assembly;

[0073] Cooling components, such as Figure 2 and Figure 3 As shown, it includes: a medium inlet pipe 6, a medium outlet pipe 7, and a heat exchange component; the medium inlet pipe 6 and the medium outlet pipe 7 are for passing through a cooling medium, which is water; the heat exchange component is used to cool the medium in the medium outlet pipe 7.

[0074] In this embodiment, to ensure sufficient contact between the cooling medium and the clamping forceps, and to guarantee the cooling capacity of the cooling assembly, the miniaturization of the minimally invasive electrode forceps is achieved to meet the needs of minimally invasive surgery. For example... Figure 3 As shown:

[0075] The first clamping tweezers 1 is provided with a corresponding medium inlet tube 6 and a medium outlet tube 7, which are mounted on the first clamping plate 3. Furthermore, the first clamping tweezers 1 is also provided with a through-hole 8 extending through its width, through which the medium inlet tube 6 and the medium outlet tube 7 communicate with each other, thus cooling the first clamping tweezers 1. The second clamping tweezers 2 is provided with a corresponding medium inlet tube 6 and a medium outlet tube 7, which are mounted on the second clamping plate 4. Furthermore, the second clamping tweezers 2 is also provided with a through-hole 8 extending through its width, through which the medium inlet tube 6 and the medium outlet tube 7 communicate with each other, thus cooling the second clamping tweezers 2.

[0076] Furthermore, in this embodiment, to securely and reliably limit and fix the medium inlet tube 6 and the medium outlet tube 7, ensuring stable and reliable communication between the medium inlet tube 6 and the medium outlet tube 7 and the clamping forceps, the first clamping forceps 1 has arc-shaped positioning grooves 9 on both sides of its width direction for positioning the medium inlet tube 6 and the medium outlet tube 7; the connecting hole 8 passes through two oppositely arranged arc-shaped positioning grooves 9; and the tube walls of the medium inlet tube 6 and the medium outlet tube 7 have openings communicating with the connecting hole 8. Similarly, the second clamping forceps 2 has arc-shaped positioning grooves 9 on both sides of its width direction for positioning the medium inlet tube 6 and the medium outlet tube 7; the connecting hole 8 passes through two oppositely arranged arc-shaped positioning grooves 9; and the tube walls of the medium inlet tube 6 and the medium outlet tube 7 have openings communicating with the connecting hole 8.

[0077] See Figure 2 and Figure 4 , Figure 2 An enlarged schematic diagram of the connection structure between the clamp assembly and the forceps head assembly in a forceps-type minimally invasive electrode forceps embodiment of the present invention is shown. Figure 4 A schematic diagram of the clamp drive assembly structure in a tweezer-type minimally invasive electrode forceps according to an embodiment of the present invention is shown.

[0078] The clamp drive assembly 5 includes: a pull line 10, a pull rod 11 fixedly connected to the pull line 10, and a drive handle assembly 15 for driving the pull rod 11 to extend and retract.

[0079] The first clamping piece 3 and the second clamping piece 4 are provided with a pulling hole 12 for the pulling line 10 to pass through, and the first clamping piece 3 and the second clamping piece 4 are also provided with a guide pulley 13 for guiding the pulling line 10.

[0080] The two ends of the pull line 10 are fixedly connected to the pull rod 11 and pass through the first clamp 3 and the second clamp 4 to form a Y-shaped structure. As the pull rod 11 is driven away from the clamp head assembly, the pull line 10 is tightened and drives the first clamp 3 and the second clamp 4 to move towards each other, driving the clamp head assembly to perform a clamping action.

[0081] In this embodiment, as Figure 1 As shown, the tweezer-type minimally invasive electrode forceps also includes:

[0082] The connecting sleeve 14 is used to fix the first clamping plate 3 and the second clamping plate 4 to the connecting sleeve 14, thereby limiting and fixing them. Furthermore, the first clamping plate 3 and the second clamping plate 4 are elastic elements. When the clamping plate driving assembly 5 does not apply a force toward the clamping plate assembly, the clamping head assembly remains in the open state. During the process of the pulling rod 11 being driven to approach the clamping head assembly, the pulling line 10 relaxes and releases the driving force on the first clamping plate 3 and the second clamping plate 4, and the clamping head assembly returns to the open state under its own elastic action.

[0083] In this embodiment, as Figure 4 As shown, the drive handle assembly 15 includes:

[0084] A grip handle 16 is hinged to the outer shell 20 of the forceps-type minimally invasive electrode forceps and is connected to the traction rod 11 via a rotating connecting rod 18. The grip handle 16 is hinged to the outer shell 20 on the side near the forceps head assembly. The hinge position of the grip handle 16 and the rotating connecting rod 18 is located on the side away from the forceps head assembly. The rotating connecting rod 18 is an arc-shaped component with both ends hinged to the grip handle 16 and the traction rod 11, respectively. The grip handle 16 drives the traction rod 11 away from the forceps head assembly through the rotating connecting rod 18, tightens it through the traction line 10, and drives the first clamping plate 3 and the second clamping plate 4 to move towards each other, thereby driving the forceps head assembly to perform a clamping action. Furthermore, the pull rod 11 is fitted with connecting wings 19 having connecting parts on both sides; the two grip handles 16 are respectively hinged to one of the connecting parts of the connecting wings 19 through a rotating connecting rod 18; and the elastic element 17 is a spring fixed on the outer shell 20, and the spring is abutted to the end of the connecting wing 19.

[0085] The elastic element 17 is connected to the pull rod 11. When the clamping action is performed by the clamping head assembly, the pull rod 11 compresses the elastic element 17 to deform and store energy. When the grip handle 16 releases the driving force, the elastic element 17 drives the pull rod 11 to move toward the clamping head assembly, and the pull line 10 relaxes to open the clamping head assembly.

[0086] In addition, such as Figure 5 An enlarged schematic diagram of the connection structure between the first limiting support on the outer shell and the connecting sleeve. Figure 4 The diagram shows the structure of the clamp drive assembly in the tweezer-type minimally invasive electrode forceps.

[0087] The outer casing 20 is also provided with a first limiting support 21 for limiting the connecting sleeve 14. The outer casing 20 is also provided with a second limiting support 22 for limiting the pull rod 11.

[0088] Of course, in this embodiment, the cooling medium in the medium inlet pipe 6 and the medium outlet pipe 7 is not specifically limited. In other embodiments, the cooling medium in the medium inlet pipe 6 and the medium outlet pipe 7 can also be cooling air or other cooling media.

[0089] Of course, this embodiment does not specifically limit whether or not to set the above-mentioned cooling component. In other embodiments, the tweezer-type minimally invasive electrode forceps do not need to be equipped with a cooling component.

[0090] Of course, the specific structure of the cooling component is not specifically limited in this embodiment. In other embodiments, the cooling component may also be a TEC semiconductor cooler or other cooling structures.

[0091] Of course, the specific structure of the clip driving component 5 is not specifically limited in this embodiment. In other embodiments, the first clip 3 and the second clip 4 can also be driven to move towards each other or away from each other by a micro motor or other structure.

[0092] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
