Description

Technical Field

[0001] The utility model relates to the technical field of medical care products, in particular to a flexibly adjustable laparoscopic surgical tissue grasping forceps. Background Art

[0002] Due to technological advances, minimally invasive surgery has become an important surgical treatment method. Laparoscopic instruments make it possible to perform surgery through smaller incisions. In this way, the damage to tissues is less than that of traditional surgery. Through minimally invasive incisions, surgeons can insert small light sources, cameras, surgical instruments, etc. to perform surgical operations. Surgeons can guide the operation of surgical instruments to perform minimally invasive surgery through images transmitted to the accompanying monitor. This type of surgery is called laparoscopic surgery when performed in the abdominal cavity, arthroscopic surgery when performed in the joints, and thoracoscopic surgery when performed in the chest cavity. Because it causes less damage than traditional open surgery, laparoscopic surgery has many advantages, including shorter hospital stays (in most cases), less pain after surgery, earlier return to work, and smaller surgical scars.

[0003] For various existing laparoscopic surgeries, various laparoscopic tissue grasping forceps are generally used. For details, please refer to the attached drawings of this patent specification. Fig. 9 As shown, although it is widely used, the inventor of this patent found in his work that it still has certain defects and shortcomings in use.

[0004] Specifically, on the one hand, when the depth of laparoscopic surgery is shallow, a shorter laparoscopic tissue grasping forceps is needed for use; when the depth of laparoscopic surgery is deep, a longer laparoscopic tissue grasping forceps is needed for use; that is to say, the length of existing laparoscopic tissue grasping forceps cannot be flexibly adjusted, making it inconvenient to grasp laparoscopic surgical tissues at different depths, so that its adaptability is not strong; on the other hand, the grasping angle of the existing laparoscopic tissue grasping forceps for laparoscopic surgery tissues cannot be flexibly adjusted, so that the surgeon needs to frequently change the gripping angle to grasp the laparoscopic surgical tissue at a suitable grasping angle, but this will increase the fatigue of the surgeon.

[0005] In this regard, the inventor of this patent combined clinical experience, thought about the problems encountered in clinical work, read a large amount of scientific research materials and literature, and through retrieval and novelty search, gradually conceived and designed this application to solve related technical problems.

[0081] The flexibly adjustable laparoscopic surgical tissue grasping forceps 1000 according to an embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0082] Reference Figure 1 to Figure 2As shown, the laparoscopic surgical tissue grasping forceps 1000 provided according to the embodiment of the utility model comprises a handle 10, a hollow connecting rod 20 connected forwardly to the upper part of the handle 10 and having both front and rear ends open, a length adjustment rod 30 whose rear half can slide forward and backward and is clamped in the hollow connecting rod 20, a grasping forceps 40 fixedly arranged at the front end of the length adjustment rod 30 and tilted forward and downward, and a control member 50 for controlling the grasping forceps 40 to automatically close to grasp the laparoscopic surgical tissue;

[0083] The control member 50 is connected between the grasping forceps 40 and the handle 10 ; a locking hole 201 is formed on the front end outer wall of the hollow connecting rod 20 , and a locking bolt 202 is screwed in from the locking hole 201 and abuts against the outer wall of the length adjustment rod 30 .

[0084] When the locking bolt 202 is loosened, the length of the rear half of the length adjustment rod 30 extending out of the front end opening of the hollow connecting rod 20 can be adjusted, so that the distance between the grasping forceps 40 and the handle 10 can be adjusted.

[0085] Based on the above, it is clear that when the present application is implemented, it is mainly used as a flexibly adjustable laparoscopic surgical tissue grasping forceps 1000.

[0086] Specifically, when applying the present application, the locking bolt 202 is loosened so that the length of the rear half of the length adjustment rod 30 extending out of the front end opening of the hollow connecting rod 20 can be adjusted. When the length of the rear half extending out of the front end opening of the hollow connecting rod 20 is adjusted to the desired length, the locking bolt 202 can be tightened again, thereby making the distance between the grasping forceps 40 and the handle 10 adjustable.

[0087] The use of the above-mentioned application will obviously have the following technical effects:

[0088] First, the distance between the grasping forceps 40 and the handle 10 is adjustable, so that no matter whether the depth of the laparoscopic surgery is shallow or deep, the distance between the grasping forceps 40 and the handle 10 can be flexibly adjusted according to actual needs, so that the overall length of the application can be variable during specific use, making it highly flexible and adaptable to use.

[0089] Second, the surgeon can control the grasping forceps 40 to automatically close to grasp the tissue for laparoscopic surgery by operating the control member 50, making the present application easy to operate.

[0090] Furthermore, through the above-mentioned optimized design, the overall structure of the present application is highly practical and has good use effect.

[0091] Furthermore, in the specific implementation, Figure 2 and Figure 3 As shown, according to one embodiment of the utility model, the outer wall of the length adjustment rod 30 is evenly cut from front to back with multiple circles of annular limiting grooves 301 adapted to fit the inner end of the locking bolt 202 extending therein, and the front-to-back length of the annular limiting groove 301 is slightly larger than the outer diameter of the inner end of the locking bolt 202.

[0092] In this regard, it can be understood that, after the surgeon loosens the locking bolt 202 outward and adjusts the length adjustment rod 30 forward and backward until any of the annular limit grooves 301 is opposite to the inner end of the locking bolt 202, the surgeon can tighten the locking bolt 202 again to make its inner end extend into the annular limit groove 301 opposite to its position. In this way, the front and rear position of the length adjustment rod 30 cannot be easily moved at this time, so that the length of the rear half extending out of the front end opening of the hollow connecting rod 20 is adjusted to the desired length, and the fixing stability and reliability of use are good.

[0093] Furthermore, in the specific implementation, Figure 1 , Figure 2 and Figure 3 As shown, according to one embodiment of the utility model, a strip viewing window 203 is opened along the front-to-back direction on the outer wall of the front end of the hollow connecting rod 20, facing the inner end of the locking bolt 202, and the front-to-back length of the strip viewing window 203 is slightly larger than the front-to-back length of the annular limiting groove 301.

[0094] In this regard, it is clear that when the locking bolt 202 is loosened outward and the length adjustment rod 30 is adjusted forward and backward, the surgeon can control the required position of the annular limit groove 301 through the strip viewing window 203 to make it face the inner end of the locking bolt 202. In this way, it is easy to quickly align the position so that when the locking bolt 202 is tightened again, the inner end of the annular limit groove 301 is extended into the annular limit groove 301 opposite to its position to lock and fix the length adjustment rod 30.

[0095] Furthermore, through the above-mentioned optimization design, the overall use effect of the present application can be effectively improved.

[0096] In addition, in the technical solution of this application, continue to compare Figure 1 , Figure 2 and Figure 3 As shown, according to an embodiment of the present utility model, a circle of rotating convex 302 is provided outwardly on the outer wall of the middle part of the length adjustment rod 30, and an anti-slip convex strip 3021 is provided on the outer wall of the rotating convex 302;

[0097] Initially, the rear end of the rotating convex portion 302 abuts against the front end of the hollow connecting rod 20 ; when the rotating convex portion 302 is rotated, the grasping angle of the grasping forceps 40 grasping the tissue for laparoscopic surgery is adjustable.

[0098] Therefore, it is clear that the surgeon can easily drive the length adjustment rod 30 and the grasping forceps 40 fixed at the front end to rotate 360 ​​degrees by twisting the rotating protrusion 302, so that the grasping angle of the grasping forceps 40 for grasping the laparoscopic surgical tissue can be adjusted.

[0099] Furthermore, through the above-mentioned optimized design, the surgeon does not need to frequently change the gripping angle to grasp the laparoscopic surgical tissue at a suitable grasping angle, which can greatly reduce the surgeon's fatigue.

[0100] Furthermore, through the above-mentioned optimization design, the overall use effect of the present application can be further improved.

[0101] And for the use of the above application, refer to Figure 2 As shown, a soft rubber block 2021 that can be tightened to the bottom of any of the annular limiting grooves 301 can also be provided at the inner end of the locking bolt 202. When the surgeon screws the rotating convex 302 to drive the length adjustment rod 30 and the grasping forceps 40 fixed at its front end to rotate 360 ​​degrees to adjust the grasping angle of the grasping forceps 40 for grasping the laparoscopic surgical tissue, on the one hand, the inner end of the locking bolt 202 is maintained in the relative position of the annular limiting groove 301, so that when the length adjustment rod 30 and the grasping forceps 40 fixed at its front end rotate 360 ​​degrees, the whole formed by them is not easy to shift forward and backward, so that the present application is reliable to use. For details, please refer to Figure 7 As shown, Figure 7 This is a diagram of the flexibly adjustable laparoscopic surgical tissue grasping forceps 1000 of the utility model in use when the length is adjusted to the longest. On the other hand, the soft rubber block 2021 arranged at the inner end of the locking bolt 202 is pressed against the bottom of the annular limiting groove 301 opposite to it, so that a certain rotational damping effect can be provided, so that the length adjustment rod 30 and the grasping forceps 40 fixed at its front end can maintain good stability after rotation. When it drives the grasping forceps 40 to rotate to the desired grasping angle, the grasping forceps 40 can be maintained at the desired grasping angle, so that the entire application is more stable and reliable to use.

[0102] Furthermore, in the specific implementation, it is still necessary to refer to Figure 1 , Figure 2 and Figure 3 As shown, according to an embodiment of the present invention, the front end of the length adjustment rod 30 is bent forward and downward to form a bending portion 303 ; the grasping forceps 40 are fixed to the bending portion 303 .

[0103] Preferably, in the present technical solution, according to an embodiment of the utility model, the central axis of the bending portion 303 and the central axis of the length adjustment rod 30 are in the same plane, and the angle between the central axis of the bending portion 303 and the central axis of the length adjustment rod 30 is R; R = 105 degrees - 135 degrees.

[0104] And preferably, in the present technical solution, the R is set to 120 degrees.

[0105] Again, in the specific implementation, Figure 4 , Figure 5 and Figure 6 As shown, according to one embodiment of the present utility model, the grasping forceps 40 includes a first clamping jaw 401, a second clamping jaw 402, a rotating shaft A403 and a torsion spring 404;

[0106] Among them, the first clamping jaw 401 and the second clamping jaw 402 are arranged crosswise; the upper middle part of the first clamping jaw 401 and the upper middle part of the second clamping jaw 402 are rotatably connected through the rotating shaft component A403; the rotating shaft component A403 is fixed to the bending portion 303; the torsion spring 404 is sleeved on the outside of the rotating shaft component A403, and its first torque end 4041 is against the inner end surface of the upper middle part of the first clamping jaw 401, and its second torque end 4042 is against the inner end surface of the upper middle part of the second clamping jaw 402, so as to open the first clamping jaw 401 and the second clamping jaw 402.

[0107] Therefore, it can be clearly seen that in the natural state, the first clamping jaw 401 and the second clamping jaw 402 are in an open state, so as to facilitate preparation for grasping tissue for laparoscopic surgery.

[0108] It should be added that, in the specific implementation, continue to compare Figure 4 , Figure 5 and Figure 6 As shown, according to an embodiment of the present invention, the lower inner end surface of the first clamping jaw 401 and the lower inner end surface of the second clamping jaw 402 are both formed into a sawtooth shape.

[0109] Thus, even when the first clamping jaw 401 and the second clamping jaw 402 are closed toward each other, the grasping space formed therebetween can well bite the laparoscopic surgical tissue to be grasped, so that the grasped laparoscopic surgical tissue has good grasping and clamping properties and is not easy to fall off.

[0110] It is further necessary to add that in the specific implementation, Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, according to one embodiment of the present utility model, the control member 50 includes a T-shaped operating handle 501, a pull rope winding bolt 502 and a pull rope 503;

[0111] The length adjustment rod 30 and the bending portion 303 connected thereto are both hollow structures, and a through hole is formed at the rear end of the length adjustment rod 30; the front end of the bending portion 303 is formed as an open opening; the rotating shaft A403 is fixed in the bending portion 303 and close to the front end opening; the upper middle portion of the first clamping jaw 401 and the upper middle portion of the second clamping jaw 402 both extend from the open opening into the bending portion 303 and are rotatably connected through the rotating shaft A403;

[0112] In addition, the T-shaped operating handle 501 is arranged at the rear end of the handle 10 in an inclined manner upward and backward, and its front upper end is rotatably connected to the middle part of the handle 10 through a rotating shaft B504, and a screw hole 5011 is opened downward at its rear upper end; the lower end of the pull rope winding bolt 502 is screwed into the screw hole 5011;

[0113] The pull rope 503 is in a tensioned state and is passed through the length adjustment rod 30 and the bending portion 303. The rear end thereof extends out of the opening and is connected to the middle outer wall of the pull rope winding bolt 502. The front end thereof is forked to form a first connection portion 5031 connected to the upper end of the first clamp 401 and a second connection portion 5032 connected to the upper end of the second clamp 402.

[0114] In this regard, it is clear that when the surgeon grips the handle 10 and the T-shaped operating handle 501, the upper rear end of the T-shaped operating handle 501 will pull the pull rope 503 backwards, and the first connecting portion 5031 and the second connecting portion 5032 provided at the front end of the pull rope 503 will correspondingly pull the upper end of the first clamping jaw 401 and the upper end of the second clamping jaw 402 backwards, so as to drive the upper end of the first clamping jaw 401 and the upper end of the second clamping jaw 402 to move closer together, and then realize the closure between the lower middle portion of the first clamping jaw 401 and the lower middle portion of the second clamping jaw 402, so as to finally achieve the grasping of laparoscopic surgical tissue. For details, please refer to Figure 8 shown.

[0115] Moreover, in the use of the above-mentioned present application, compared with the traditional laparoscopic tissue grasping forceps 40 provided with a grip ring, the present application is for the surgeon to hold the grip 10 and the T-shaped operating handle 501 tightly, and the gripping force is in the front-to-back direction, so that it is convenient to apply force, so that the operation is effortless.

[0116] It is further necessary to add that in the specific implementation, Figure 1 , Figure 2 and Figure 4 As shown, according to an embodiment of the utility model, it also includes a lighting lamp bead 60 fixed in the bending portion 303 and an electrical connection line 70 that is inserted into the length adjustment rod 30 and extends out of the port at the rear end;

[0117] The front end of the power connection line 70 is connected to the lighting lamp bead 60 , and the rear end is provided with a power terminal 701 . The length of the rear end of the power connection line 70 extending out of the opening is equal to or greater than the front-to-rear length of the hollow connecting rod 20 .

[0118] In this regard, it can be clearly seen that when the present application is actually used, a lighting lamp bead 60 is also provided to provide lighting. After the power terminal 701 is externally connected to a matching power supply device, the lighting lamp bead 60 can be lit. The light emitted by the lighting lamp bead 60 can be emitted through the front end of the bending portion 303 to illuminate the laparoscopic surgical tissue grasping site, so that a better operating field of view can be provided, so that the overall use effect of the present application is better.

[0119] It should also be added that, in a specific implementation, according to the flexibly adjustable laparoscopic tissue grasping forceps 1000 provided in an embodiment of the utility model, the interior of the length adjustment rod 30 described in the present application is divided into a first channel (not shown) and a second channel (not shown) connected to the bending portion 303 along the front-to-back direction, the pull rope 503 is directly inserted in the first channel (not shown) and can be pulled forward and backward relative to the first channel (not shown), and the electrical connection line 70 is fixed to the second channel (not shown) by a strong adhesive.

[0120] In this way, when the present application is actually used, the pull rope 503 and the power connection line 70 are separated from each other, so that they are not easy to get tangled when moving forward and backward, so that the overall stability and reliability of the present application are better.

[0121] And in the specific implementation, the reference Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the present application also includes a reset spring 80, a plug-in block A101 is provided at the rear middle and lower portion of the handle 10, a plug-in block B5012 is provided at the front middle and lower portion of the T-shaped operating handle 501, and the front and rear ends of the reset spring 80 are correspondingly sleeved on the outside of the plug-in block A101 and the plug-in block B5012.

[0122] Initially, the reset spring 80 is in a natural state or a slightly compressed state, the grasping forceps 40 is in an open state under the torque of the torsion spring 404, and the pull rope 503 is in a straightened state. When the surgeon holds the handle 10 and the T-shaped operating handle 501 tightly, the reset spring 80 continues to be compressed, and the upper rear end of the T-shaped operating handle 501 will pull the pull rope 503 backward, and the first connecting part 5031 and the second connecting part 5032 set at the front end of the pull rope 503 will correspondingly pull the upper end of the first jaw 401 and the upper end of the second jaw 402 to drive the upper end of the first jaw 401 and the upper end of the second jaw 402 to move closer together, so that the lower middle part of the first jaw 401 and the lower middle part of the second jaw 402 are closed, so as to finally grasp the laparoscopic surgical tissue.

[0123] On the contrary, when the surgeon releases the grip 10 and the T-shaped operating handle 501, the reset spring 80 will be reset to the initial state, the torsion spring 404 will also be reset to the initial state, and the lower middle portion of the first clamping jaw 401 and the lower middle portion of the second clamping jaw 402 will open back to back.

[0124] Regarding the use of the above-mentioned application, it should be noted here that:

[0125] First, by setting the reset spring 80, a certain gripping reaction force can be provided, so that the surgeon can have a better feel when applying force and can better control the gripping strength. At the same time, when it is reset, it is also convenient for the lower and middle parts of the first clamping jaw 401 and the second clamping jaw 402 to quickly open back to the initial state.

[0126] Second, when the locking bolt 202 is loosened to adjust the front and rear position of the length adjustment rod 30, the pull rope winding bolt 502 can be appropriately rotated to ensure that after the front and rear position of the length adjustment rod 30 is adjusted and fixed, the pull rope 503 can still be kept in a straightened state to facilitate the reliable use of the present application.

[0127] At the same time, in this application, the reference Figure 6 As shown, the middle positions of the lower middle portion of the first clamping jaw 401 and the lower middle portion of the second clamping jaw 402 are hollowed out to form a first grasping cavity 4011 and a second grasping cavity 4021 respectively, so that when they are closed to grasp the laparoscopic surgical tissue, more laparoscopic surgical tissue can be grasped at one time, and the grasped laparoscopic surgical tissue is not easy to slip off as a whole because it is partially clamped in the first grasping cavity 4011 and the second grasping cavity 4021.

[0128] Therefore, through the above-mentioned optimized design, the overall use effect of the present application can be achieved to the best.

[0129] Other embodiments and the like are not described here by way of example.

[0130] To summarize, the flexibly adjustable laparoscopic surgical tissue grasping forceps 1000 provided in the present application, during specific implementation, the distance between the grasping forceps 40 and the handle 10 is adjustable, so that no matter whether the depth of the laparoscopic surgery is shallow or deep, the distance between the grasping forceps 40 and the handle 10 can be flexibly adjusted according to actual needs, so that the overall length of the present application can be variable during specific use, making it highly flexible and adaptable to use.

[0131] Furthermore, the surgeon can easily drive the length adjustment rod 30 and the grasping forceps 40 fixed at the front end thereof to rotate 360 ​​degrees by twisting the rotating protrusion 302, so that the grasping angle of the grasping forceps 40 for grasping the tissue for laparoscopic surgery can be adjusted.

[0132] In actual use, the present application is also provided with an illumination lamp bead 60 for providing lighting. After the power terminal 701 is externally connected to a matching power supply device, the illumination lamp bead 60 can be lit. The light emitted by the illumination lamp bead 60 can be emitted through the front end of the bending portion 303 to illuminate the laparoscopic surgical tissue grasping site, thereby providing a better operating field of view, so that the overall use effect of the present application is better.

[0133] Furthermore, the flexibly adjustable laparoscopic surgical tissue grasping forceps 1000 provided by the present application is indeed extremely practical and has an excellent use effect, which makes the present application bound to have a good market promotion value, and the present application is bound to be very popular and will be effectively popularized.
