Background

When the laparoscopic surgery is performed on a human body, although the wound is small, the diseased tissue needs to be removed, blood vessels are inevitably cut in the surgical process, and the phenomenon of local bleeding occurs. The electric coagulation hemostasis is a medical means which utilizes the heat effect of high-frequency current to dehydrate and shrink the vessel wall, coagulate blood in the vessel and fuse the blood vessel and blood clot into a whole so as to achieve the aim of effective hemostasis.

As shown in fig. 1 to 20, the present embodiment provides an electrocoagulation lymph surgical forceps, comprising:

the control handle 1 comprises a fixed handle 11 and a movable handle 12 which are hinged with each other;

the fixing handle 11 is provided with a through mounting cavity 13, the tail end of the forceps tube 2 is fixedly inserted in the mounting cavity 13, and the inner core tube 3 is movably inserted in the forceps tube 2;

a first electrode 31 and a second electrode 32, the first electrode 31 and the second electrode 32 being fitted to the distal end of the core tube 3, and the first electrode 31 and the second electrode 32 being insulated from each other;

a sliding member 14, wherein the sliding member 14 is slidably assembled in the installation cavity 13 along the length direction of the forceps tube 2, the tail end of the inner core tube 3 extends out of the tail end of the forceps tube 2 and is fixedly connected with the sliding member 14, and the movable handle 12 is slidably connected with the sliding member 14;

the tong head 4 is arranged at the head end of the tong pipe 2; the binding clip 4 comprises a first binding clip 41 and a second binding clip 42 which are hinged to each other, a first lead 33 and a second lead 34 are arranged in the tube of the inner core tube 3, the head ends of the first lead 33 and the second lead 34 are respectively in control connection with the first binding clip 41 and the second binding clip 42, and the tail ends of the first lead 33 and the second lead 34 are respectively in electric connection with the first electrode 31 and the second electrode 32.

When in use, as shown in fig. 1 to 3, the movable handle 12 can be controlled to rotate to approach the fixed handle 11, and the movable handle 12 can synchronously control the sliding of the sliding member 14 in the mounting cavity 13 along with the rotation of the movable handle 12. For example, the mounting cavity 13 includes: a linear sliding cavity 131 and a rotating cavity 132 which are communicated with each other, wherein a linear track formed by the linear sliding cavity 131 is parallel to the forceps tube 2, the sliding member 14 is slidably assembled in the linear sliding cavity 131 along the linear track, and the movable handle 12 is hingedly assembled in the rotating cavity 132; a control rod 141 is arranged at the end of the movable handle 12, a control groove 142 opposite to the control rod 141 is arranged on the sliding member 14, and the top end of the control rod 141 is movably inserted in the control groove 142. Meanwhile, a gasket is padded between the splicing cap 15 and the linear sliding cavity 131. The gasket can be made of rubber or plastic, and the gasket can be made of a suitable material according to requirements by those skilled in the art, which is not described herein in detail.

Therefore, as the movable handle 12 rotates, the control rod 141 at the end of the movable handle 12 applies a force to the groove wall of the control groove 142, so that the movable handle 12 can synchronously control the sliding member 14 to slide linearly in the linear sliding cavity 131 by the driving force between the control rod 141 and the control groove 142. At this time, when the sliding body 14 moves towards the distal end of the lymphatic surgical forceps, the inner core tube 3 can be synchronously driven to move towards the distal end of the lymphatic surgical forceps relative to the forceps tube 2, and at the same time, since the first electrode 31 and the second electrode 32 are assembled at the distal end of the inner core tube 3, the distal ends of the first lead 33 and the second lead 34 are respectively electrically connected with the first electrode 31 and the second electrode 32, and therefore, the first lead 33 and the second lead 34 are synchronously driven to move towards the distal end of the lymphatic surgical forceps relative to the forceps tube 2.

Since the head ends of the first lead 33 and the second lead 34 are respectively connected with the first forceps head 41 and the second forceps head 42 in a control manner, when the first lead 33 and the second lead 34 move relative to the forceps tube 2 towards the tail end of the lymphatic surgical forceps, a pulling action is formed on the tail ends of the first forceps head 41 and the second forceps head 42 which are hinged to each other and assembled at the head end of the forceps tube 2, and the first forceps head 41 and the second forceps head 42 which are hinged to each other relatively rotate along the hinged parts under the pulling action, so that the first forceps head 41 and the second forceps head 42 are combined or occluded.

When the movable handle 12 is controlled to rotate away from the fixed handle 11, the movable handle 12 synchronously controls the sliding member 14 to slide in the mounting cavity 13 in the opposite direction along with the rotation of the movable handle 12. For example, as the movable handle 12 rotates, the control rod 141 at the end of the movable handle 12 applies a force to the wall of the control slot 142, so that the movable handle 12 can synchronously control the slider 14 to slide linearly in the linear sliding cavity 131 by the driving force between the control rod 141 and the control slot 142.

At this time, when the sliding body 14 moves towards the head end of the lymphatic surgical forceps, the inner core tube 3 can be synchronously driven to move towards the head end of the lymphatic surgical forceps relative to the forceps tube 2, and at the same time, the first lead 33 and the second lead 34 need to have certain hardness, so that the first lead 33 and the second lead 34 are synchronously driven to move towards the head end of the lymphatic surgical forceps relative to the forceps tube 2 under the driving of the movement of the inner core tube 3, and at this time, the first forceps head 41 and the second forceps head 42 rotate along the mutually hinged parts and are separated from each other.

In addition, the lymphatic forceps may further include: piece together cap 15, piece together cap 15 fixed mounting in the straight line slides in the chamber 131, the end of tong pipe 2 through with piece together cap 15 fixed socket joint with fixed grafting in the installation cavity 13, piece together cap 15 with be connected with at least one extension spring 16 between the slider 14. The two ends of the tension spring 16 can be connected with the splicing cap 15 and the sliding piece 14 in a hanging mode, or can be connected with the splicing cap 15 and the sliding piece 14 in a clamping mode, and the tension spring can be set by a person skilled in the art according to requirements and is not described in detail herein.

Therefore, since the cap piece 15 is fixedly installed in the linear sliding cavity 131, the tension spring 16 will form an elastic pulling force between the cap piece 15 and the slider 14, and when the control force on the movable handle 12 is lost, the elastic pulling force will pull the slider 14 to move toward the head end of the lymphatic surgical forceps, so as to restore to the original state. In synchronization with this, the inner core tube 3 and the first and

second wires

33 and 34 are moved toward the head end of the lymphatic surgical forceps, and the first and second forceps heads 41 and 42 are rotated along the hinged portions to be separated from each other.

In addition, the slider member 14 may have a cylindrical structure, or at least a portion of the slider member 14 may have a cylindrical structure. The part of the columnar structure of the slider 14 or the columnar slider 14 can be conveniently assembled with the linear sliding cavity 131 in a sliding manner, and a person skilled in the art can set the shape of the slider 14 according to requirements, which is not described herein.

Therefore, the control handle 1 of the electric coagulation forceps adopts a gun type control structure, and the movement operation of the hand is more suitable when the fixed handle 11 and the movable handle 12 are relatively controlled. Moreover, in the process of controlling the movable handle 12 to rotate and approach or separate relative to the fixed handle 11, the slider 14, the inner core tube 3, the first lead 33 and the second lead 34 can be directly and completely synchronously controlled to reciprocate, the control effect of the synchronous motion can control the opening and closing of the forceps head 4 more accurately, the opening and closing of the forceps head 4 is highly consistent with the rotating operation of the movable handle 12, and the operation accuracy is ensured while the operation convenience is improved.

As shown in fig. 13, the tube wall of the inner core tube 3 is provided with a first electrode 31 hole and a second electrode 32 hole, the first electrode 31 is exposed out of the first electrode 31 hole, and the second electrode 32 is exposed out of the second electrode 32 hole. At this time, the first electrode 31 and the first electrode 31 exposed in the first electrode 31 hole and the second electrode 32 hole can be used to connect with an external power source, thereby supplying power to the lymphatic surgical forceps. The end of the sliding member 14 may be further provided with an open slot, so that the inner cavity of the open slot is larger than the diameter of the inner core tube 3, which may facilitate the power supply connection between the external power supply and the first electrode 31 and the second electrode 32 at the end of the sliding member 14, and may also facilitate the fixing and installation of the connection part.

Continuing to refer to FIG. 13, further comprising: a first insulating sleeve 37 and a second insulating sleeve 38, wherein the first insulating sleeve 37 and the second insulating sleeve 38 are sleeved at the tail end of the inner core tube 3 at intervals, and the first electrode 31 hole is positioned between the first insulating sleeve 37 and the second insulating sleeve 38. The first insulating sleeve 37 and the second insulating sleeve 38 can be used to separate the first electrode 31 hole from the second electrode 32 hole, and since the first electrode 31 hole is located between the first insulating sleeve 37 and the second insulating sleeve 38, the first electrode 31 hole and the second electrode 32 hole can be separated by at least the first insulating sleeve 37 or the second insulating sleeve 38.

In this case, the second electrode 32 hole may be provided on the side facing the head end of the forceps with respect to the first insulating sheath 37, or may be provided on the side facing the tail end of the forceps with respect to the second insulating sheath 38. Preferably, the second electrode 32 aperture is disposed at the end of the slider member 14, which facilitates direct connection of an external power source to the second electrode 32 from the end of the slider member 14.

Therefore, the positions of the holes of the first electrode 31 and the second electrode 32 can be determined through the definition of the positions of the holes of the first electrode 31 and the holes of the second electrode 32, so that the positions of the exposed positions of the first electrode 31 and the second electrode 32 are ensured to be insulated and isolated by the first insulating sleeve 37 and the second insulating sleeve 38, and the use safety of the surgical forceps is ensured.

As shown in fig. 2, the method further includes: a first connecting piece 35 and a second connecting piece 36; one end of the first connecting piece 35 is hinged to the end of the first binding clip 41, and the other end of the first connecting piece 35 is connected to the first lead 33; one end of the second connecting piece 36 is hinged to the end of the second binding clip 42, and the other end of the second connecting piece 36 is connected to the second wire 34.

Therefore, the first connecting piece 35 and the second connecting piece 36 are indirectly hinged and assembled between the first tong head 41 and the first lead 33 and between the second tong head 42 and the second lead 34, so that the relative rotation and the engagement or disengagement of the first tong head 41 and the second tong head 42 can be more flexibly controlled.

As shown in fig. 4 to 7, the mounting cavity 13 further includes:

a seat cavity 133, the seat cavity 133 communicating with the linear sliding groove along the length direction of the forceps tube 2;

the runner seat 134 is provided with a through hole, the runner seat 134 is fixedly sleeved outside the clamp tube 2, the runner seat 134 comprises an insertion end and a fixed end, and the insertion end is rotatably inserted into the seat body cavity 133;

a rotating wheel 135, the rotating wheel 135 being mounted at the fixed end.

Therefore, the rotating wheel 135 can be controlled to rotate, so as to drive the rotating wheel seat 134 to rotate. Because the rotating wheel seat 134 is fixedly sleeved outside the clamp tube 2, when the rotating wheel 135 rotates, the rotating wheel 135, the rotating wheel seat 134 and the clamp tube 2 can be synchronously controlled to synchronously rotate relative to the inner core tube 3.

In cooperation, the first binding clip 41 comprises a first binding clip rod 411 and a first clamping head 412 which are connected, and the second binding clip 42 comprises a second binding clip rod 421 and a second clamping head 422 which are connected; the first jaw bar 411 and the second jaw bar 421 are hinge-assembled with each other, the first clamping head 412 is bent 28 ° to 32 ° with respect to the first jaw bar 411, and the second clamping head 422 is bent 28 ° to 32 ° with respect to the second jaw bar 421. For example, the first clamping head 412 is bent 28 °, 29 °, 30 °, 31 °, or 32 ° with respect to the first jaw lever 411; alternatively, the second clamping head 422 is bent 28 °, 29 °, 30 °, 31 °, or 32 ° with respect to said second jaw bar 421. For the specific bending angle, those skilled in the art can set the bending angle as required, which is not described herein.

Therefore, the angle of the forceps head 4 can be indirectly adjusted by controlling the rotation angle of the forceps tube 2, so that the direction of the operation can be adjusted according to different requirements of the operation. Preferably, the first holding head 412 and the second holding head 422 are combined to form an oval shape, i.e., a bullet-like shape.

A first spring slot 1341 may be formed in a side wall of the seat body cavity 133, a first spring retractable clip 1342 may be installed in the first spring slot 1341, and a corresponding slot 1343 corresponding to the first spring retractable clip 1342 may be formed in a side wall of the runner seat 134. Therefore, after the insertion end of the runner seat 134 is inserted into the seat cavity 133, the first spring retractable clip 1342 can abut against the sidewall of the runner seat 134, and after the first spring retractable clip 1342 is clipped into the clip groove 1343, the insertion of the runner seat 134 can be limited, so as to ensure that the runner seat 134 can be stably inserted into the seat cavity 133.

Similarly, a second spring groove 1351 may be further formed in a side wall of the wheel seat 134, a second spring retractable clip 1352 may be mounted in the second spring groove 1351, and a clip hole 1353 corresponding to the first spring retractable clip 1342 may be formed in the wheel 135, for example, the wheel 135 is of a sleeve structure, and the clip hole 1353 may be formed in an inner cavity of the wheel 135 and penetrate through a wall of the inner cavity. Therefore, when the rotating wheel 135 is sleeved with the rotating wheel seat 134, the second spring telescopic clamping piece 1352 can abut against the inner cavity wall of the rotating wheel 135, and after the second spring telescopic clamping piece 1352 is clamped into the clamping hole 1353, the rotating wheel 135 and the rotating wheel seat 134 can be sleeved and assembled relatively to form a limit position. In addition, a gasket is further arranged between the runner seat 134 and the seat body cavity 133 in a cushioning manner. The gasket can be made of rubber or plastic, and the gasket can be made of a suitable material according to requirements by those skilled in the art, which is not described herein in detail.

As shown in fig. 8 to 10, the inner end of the slider 14 is opened with a limiting groove 143 opposite to the end of the forceps tube 2, and the end of the forceps tube 2 slides along the limiting groove 143 to be limited and inserted into the linear sliding cavity 131 along with the reciprocating sliding of the slider 14. Therefore, when the sliding member 14 reciprocates in the linear sliding cavity 131, the end of the clamp tube 2 can be slidably inserted into the limiting groove 143, and the sliding track of the sliding member 14 can be limited by the slidable insertion between the end of the clamp tube 2 and the limiting groove 143, so that the sliding member 14 is not deviated from the predetermined sliding track, and the control of the relative engagement or separation of the first tong head 41 and the second tong head 42 during operation can be more stable.

Referring to fig. 14 to 20, the control lever 141 includes a shaft 144 and a movable head 145 connected to each other. The top end of the shaft 144 is provided with a rotary connector 146 for assembling the movable head 145, and the movable head 145 is internally provided with a rotary groove for inserting and assembling the rotary connector 146. Therefore, when the movable head 145 is movably mounted on the rotary connector 146, the movable head 145 can rotate freely.

When the control rod 141 is movably inserted into the control slot 142, the movable head 145 is in contact with the inner slot wall of the control slot 142, so that the movable head 145 can freely rotate when being controlled and driven relative to the control slot 142 along with the movement of the movable handle 12, thereby improving the control flexibility of free sliding of the movable handle 12 and the sliding member 14.

The rotary connector 146 may be a cylindrical rotating shaft structure. Preferably, the rotating connector 146 is a sphere structure, and the rotating groove is also configured as a matched sphere structure, at this time, after the rotating groove is movably sleeved on the rotating connector 146, the rotating groove can be rotated at will in a three-dimensional angle, so that the flexibility of controlling the free sliding of the movable handle 12 and the sliding member 14 is further improved.

The rotating groove may also be sleeved on at least a half of the surface area of the rotating connector 146, rather than wrapping the entire rotating connector 146. For example, the rotation groove may be sleeved on two thirds of the surface area of the rotation connector 146, at this time, a flexible sleeving structure may be formed between the rotation groove and the rotation connector 146, and the end of the movable head 145 may not touch the shaft 144, so that the movable head 145 may flexibly rotate on the connector through the sleeving structure between the rotation groove and the rotation connector 146, thereby achieving a three-dimensional rotation effect, that is, a universal rotation effect, rather than being limited to a two-dimensional rotation effect. The size of the rotating groove and the size of the connector can be set by a person skilled in the art according to requirements, so that the rotating groove and the connector are flexibly sleeved, and a preset flexible rotating effect is realized.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
