Description

Technical Field

[0001] This invention relates to the field of intestinal tract grasping forceps, specifically to an intestinal tract grasping forceps for laparoscopic procedures. Background Technology

[0002] Colorectal cancer is one of the most common malignant tumors in my country, and comprehensive treatment, primarily surgery, is an important means of curing it. With the increasing acceptance of minimally invasive techniques and the development of related laparoscopic instruments, laparoscopic radical resection of colorectal cancer is being chosen by more and more patients. In laparoscopic colorectal cancer surgery, especially low rectal cancer surgery, rectal dissection is a crucial step. The surgeon must precisely dissect along the plane of the rectal mesentery while avoiding damage to surrounding nerves and blood vessels. During this process, the assistant must continuously retract the rectum to fully expose the surgical field, ensuring that the surgeon avoids collateral damage caused by poor visualization during dissection.

[0003] The basic structure of traditional laparoscopic intestinal grasping forceps currently used in clinical practice typically includes: a fixed integrated forceps body and handle, a rigid connecting tube, a rigid metal forceps head, and a traction assembly consisting of a single pull rope. The forceps head of traditional grasping forceps is mostly a rigid flat plate or arc-shaped structure, lacking flexible deformation capability. Colorectal segments are prone to slight deformation due to peristalsis or traction, and the rigid forceps head cannot adjust its grasping shape synchronously with the deformation of the intestinal segment, resulting in easy slippage after grasping. This requires the assistant to repeatedly adjust the grasping position, prolonging the operation time and increasing the risk of intestinal injury. Summary of the Invention

[0004] The purpose of this invention is to provide an intestinal grasping forceps for laparoscopy, in order to solve the problem that the forceps heads in the prior art are mostly rigid flat or arc-shaped structures, lacking flexible deformation capabilities, and the colorectal intestinal segments are prone to slight deformation due to peristalsis or traction, which can easily lead to slippage.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a laparoscopic intestinal tract grasping forceps, comprising: a forceps body, a fixing rod fixedly connected to one side of the forceps body, a connecting tube fixedly connected to one end of the fixing rod, a gripping handle fixedly fixed to the bottom surface of the forceps body, a pressure handle rotatably mounted on the bottom side of the forceps body, and a return spring connected between the pressure handle and the gripping handle;

[0006] Two sets of clamp heads are symmetrically installed at the end of the connecting pipe. A traction assembly is installed on the inner wall of the connecting pipe. A guide part is provided at the end of the connecting pipe. A first connector is fixedly connected to the inner top wall of the pressure handle. The first connector connects the two sets of clamp heads through the traction assembly.

[0007] The first traction assembly includes a sliding frame, a buffer spring, and a first pull rope; two sets of slides are symmetrically opened on the wall of the connecting pipe, the sliding frame is slidably installed in the slides, a buffer spring is provided between the sliding frame and the inner wall of the slide, a reset shaft and a tension shaft are provided on the inner wall of the sliding frame, the first pull rope is connected between the tension shaft and the first connector, and the two sets of clamps are axially symmetrically installed on the periphery of the reset shaft.

[0008] Furthermore, the clamp head includes a first clamp bar and a second clamp bar, both of which are made of flexible material. One end of the first clamp bar is connected to a reset shaft. Guide grooves are provided on the inner walls of both the first and second clamp bars. The width of the middle section of the guide groove is greater than that of the two end sections, and the width of the guide groove decreases from the middle section to the two end sections at a constant slope. A squeezing column is slidably disposed in the guide groove. The diameter of the squeezing column is the same as the width of the middle section of the guide groove. A second traction component is provided between the squeezing column and the pressure handle.

[0009] Furthermore, the second traction assembly includes a buckle plate and a second pull rope. A pull groove is provided on the inner wall of the clamp body, and the buckle plate is slidably installed in the pull groove. A second connector is fixed on the top of the buckle plate, and the second connector is connected to the two sets of extrusion columns via the second pull rope.

[0010] Furthermore, the top walls on both sides of the first clamp bar are provided with connecting grooves, and the bottom walls on both sides of the second clamp bar are fixedly connected with connecting parts, which are rotatably connected to the connecting grooves.

[0011] Furthermore, a through hole is provided on one side of the second clamp bar, and the second pull rope passes through the through hole and connects to the second connector.

[0012] Furthermore, both the first and second clamps are made of medical-grade silicone rubber.

[0013] Furthermore, the cross-section of each pliers head is an arc-shaped plate structure, and the inner wall of each pliers head is provided with anti-slip texture.

[0014] Furthermore, the connecting pipe is threadedly engaged with the fixing rod.

[0015] Compared with existing technologies, the present invention provides an intestinal grasping forceps for laparoscopy. By setting the forceps body, forceps head, and first traction component, when the surgeon quickly or forcefully squeezes the handle, the tension transmitted through the first pull rope first acts on the sliding frame. When the forceps head expands outward under the action of the buffer spring's restoring force, the outer wall of the forceps head gradually approaches the arc-shaped flange of the guide part. When the forceps head expands to the preset maximum angle, the outer wall of the forceps head fits against the flange, and the flange generates a reverse supporting force to prevent the forceps head from expanding further outward. This effectively avoids rigid collision between the forceps head and adjacent tissues in the abdominal cavity due to excessive expansion, and at the same time prevents fatigue deformation of the metal structure of the forceps head due to excessive expansion, thus extending the service life of the instrument. The doctor can sense the clamping state through the pressure of the handle and flexibly adjust the clamping adaptability of the forceps head in the radial direction of the intestinal tract to prevent the intestinal tract from slipping due to excessively loose clamping or the intestinal wall from ischemia due to excessively tight clamping.

[0016] Through the interaction of the guide groove and the squeezing column, the forceps head can form an elliptical clamping surface, significantly increasing the contact area with the tissue. The second traction component allows for convenient control of the squeezing column's sliding, enabling the forceps head shape to be adjusted with one hand. The controllable deformation of the flexible forceps bar results in lower clamping pressure and no rigid squeezing. Combined with the buffer spring and anti-slip texture, it can stably grasp the intestinal segment, ensure stable exposure of the surgical field, reduce the risk of rectal wall ischemia, tearing, and tumor dissemination, reduce mechanical damage caused by repeated traction, alleviate postoperative inflammation levels, and help patients recover quickly. It provides a more suitable operating experience for complex intestinal scenarios. Attached Figure Description

[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] As attached Figure 1 To be continued Figure 7 As shown:

[0029] Example 1:

[0030] This invention provides a laparoscopic intestinal grasping forceps, comprising a forceps body 1, a forceps head 4, and a first traction assembly;

[0031] A fixing rod 102 is fixedly connected to one side of the clamp body 1, and a connecting tube 3 is fixedly connected to one end of the fixing rod 102. A gripping handle 2 is fixedly fixed to the bottom surface of the clamp body 1. A pressure handle 201 is rotatably mounted on the bottom side of the clamp body 1. A return spring 202 is connected between the pressure handle 201 and the gripping handle 2. The clamp body 1 is made of stainless steel or titanium alloy to provide structural support. The fixing rod 102 is fixedly connected to one side of the clamp body 1 by an integral molding method. The gripping handle 2 is fixed to the bottom of the clamp body 1 to provide the operator with the main gripping point. The pressure handle 201 is rotatably mounted on the bottom side of the clamp body 1 by a pin, forming a lever structure similar to scissors. The return spring 202 is connected between the pressure handle 201 and the gripping handle 2 so that the pressure handle 201 can automatically return to the open position when the hand is released. The gripping handle 2 is for the doctor to hold. The pressure handle 201 controls the opening and closing of the clamp head by the doctor's pressing action and is the input component of the operating force.

[0032] Two sets of clamp heads 4 are axially symmetrically installed at the end of the connecting tube 3. A traction assembly is installed on the inner wall of the connecting tube 3. A guide part 304 is provided at the end of the connecting tube 3. A first connector 203 is fixedly connected to the inner top wall of the pressure handle 201. The first connector 203 connects the two sets of clamp heads 4 through the traction assembly. The clamp head 4 is a structure of two arc-shaped plates symmetrically installed. The arc design fits the cylindrical outer surface of the intestinal tube better.

[0033] The first traction assembly includes a sliding frame 302, a buffer spring 305, and a first pull rope 303. Two sets of slide rails 301 are symmetrically arranged on the wall of the connecting pipe 3. The sliding frame 302 is slidably installed within the slide rails 301. A buffer spring 305 is provided between the sliding frame 302 and the inner wall of the slide rails 301. A reset shaft 302a and a tension shaft 302b are provided on the inner wall of the sliding frame 302. The first pull rope 303 is connected between the tension shaft 302b and the first connector 203. The two sets of clamp heads 4 are axially symmetrical. The clamp head 4 is mounted on the periphery of the reset shaft 302a. The cross-section of the clamp head 4 is an arc plate structure, and the inner wall of the clamp head 4 is provided with anti-slip texture 404. The anti-slip texture 404 is a dot-shaped raised texture, which is used to increase friction to prevent tissue slippage, while avoiding piercing tissue like a sharp hook. The connecting tube 3 is threaded with the fixing rod 102. The end of the fixing rod 102 is machined with an external thread, which forms a threaded engagement with the internal thread near the end of the connecting tube 3. This design is used to improve the convenience of assembling the clamp head 4.

[0034] The inner surface of the slide rail 301 is smooth and has been polished and coated to minimize friction when the slide frame 302 moves, ensuring efficient and smooth force transmission. The center distance between the reset shaft 302a and the tension shaft 302b on the slide frame 302 is a key design parameter that affects the transmission efficiency and the opening and closing speed of the clamp head.

[0035] When the operator quickly or forcefully squeezes the handle 201, the pulling force transmitted through the first pull rope 303 first acts on the sliding frame 302. When the clamp head 4 expands outward under the action of the buffer spring 305, the outer wall of the clamp head 4 will gradually approach the arc-shaped flange of the guide part 304. When the clamp head expands to the preset maximum angle, the outer wall of the clamp head fits with the flange, and the flange generates a reverse supporting force to prevent the clamp head from continuing to expand outward. This effectively avoids the clamp head from rigidly colliding with adjacent tissues in the abdominal cavity (such as pelvic blood vessels and bladder walls) due to excessive expansion. At the same time, it prevents the clamp head from fatigue and deformation of its own metal structure due to excessive expansion, thus extending the service life of the instrument.

[0036] Working principle: Initial state (open): Under the action of the return spring 202, the handle 201 is in the open state. At this time, the first pull rope 303 is in a relaxed state, and the buffer spring 305 pushes the sliding frame 302 to the farthest end of the slide rail 301. The sliding frame 302 pushes the root of the jaw head 4 through the return shaft 302a, causing the jaw head 4 to open outward until its outer side is blocked by the guide part 304. At this time, the jaw head is at the preset maximum and safest opening angle.

[0037] The operator pinches the pressure handle 201 against the grip handle 2. The pressure handle 201 rotates around its axis, pulling the first connecting head 203 upward, thereby tightening the first pull cord 303. The tension of the first pull cord 303 acts on the sliding frame 302 through the tension shaft 302b. The tension first overcomes the elasticity of the buffer spring 305, causing the sliding frame 302 to compress the buffer spring 305 and slide towards the proximal handle end. This process absorbs and buffers the momentary excessive gripping force applied by the hand, avoiding the impact on the intestine from the sudden forceful closure of the forceps head.

[0038] As the sliding frame 302 moves proximally, it moves the reset shaft 302a backward. The reset shaft 302a pulls the base of the clamp head 4, causing it to rotate inward around the mounting point, thereby closing the clamp head and gripping the tissue. The final gripping force is determined by the compression of the buffer spring 305, becoming gentle and controllable.

[0039] The operator releases the pressure handle 201. Under the action of the reset spring 202, the pressure handle 201 resets, and the first pull cord 303 loosens. Subsequently, the buffer spring 305 releases its elastic force, pushing the sliding frame 302 back to the distal end of the slide rail 301. The sliding frame 302 pushes the root of the forceps head 4 through the reset shaft 302a, causing the forceps head 4 to reopen until it is again limited by the guide part 304, completely releasing the tissue.

[0040] By linking the sliding distance of the sliding frame 302 with the clamping depth of the clamp head 4, the clamping state can be flexibly adjusted: the shorter the sliding distance of the sliding frame 302, the smaller the amplitude of the wedge block squeezing the clamp head 4, and the shallower the closing depth of the front end of the clamp head 4, which is suitable for scenarios where the intestinal mucosa is fragile; the longer the sliding distance of the sliding frame 302, the greater the amplitude of the wedge block squeezing, and the deeper the closing depth of the clamp head 4, which can clamp the intestinal segment and the outer mesentery with a thickness of 3-5 mm, which is suitable for scenarios where stable traction of the intestinal mesentery is required; the clamping mode can be switched without moving the entire instrument, improving the ease of operation.

[0041] When the sliding frame 302 slides, the squeezing force of its wedge-shaped squeezing block on the clamp head 4 changes linearly with the sliding distance. In the early stage of sliding, the squeezing force is small and the clamp head 4 is slightly closed, which can temporarily clamp the intestine for position adjustment. In the later stage of sliding, the squeezing force increases and the clamp head 4 is tightly closed, which can stably pull the intestine to expose the surgical area. This can avoid the rigidity problem of traditional grasping forceps that "tighten as soon as they clamp". The doctor can sense the clamping state through the pressure of the handle 201 and flexibly adjust the clamping adaptability of the clamp head 4 in the radial direction of the intestine to prevent the intestine from slipping due to too loose clamping or the intestine wall from being ischemic due to too tight clamping.

[0042] When the pressure handle 201 is released, the buffer spring 305 pushes the sliding frame 302 back to the direction of the connecting tube 3. The side wall of the sliding frame 302 can guide the repositioning direction of the forceps head 4, ensuring that the forceps head 4 always returns to the initial position that matches the guide part 304 during expansion and repositioning. This avoids positional deviation during the next clamping due to the repositioning offset of the forceps head 4. There is no need to repeatedly calibrate the position of the forceps head 4, reducing the adjustment time during the operation. Especially in continuous grasping and pulling operations, it can significantly improve the continuity and efficiency of the operation.

[0043] Example 2:

[0044] This embodiment is basically the same as the previous embodiment, except that the clamp head 4 includes a first clamp bar 401 and a second clamp bar 402. Both the first clamp bar 401 and the second clamp bar 402 are made of flexible material and are made of medical silicone rubber. One end of the first clamp bar 401 is connected to the reset shaft 302a. One end of the first clamp bar 401 is provided with an extension for connecting to the reset shaft 302a. Guide grooves 403 are provided on the inner walls of both the first clamp bar 401 and the second clamp bar 402. The width of the middle section of the guide groove 403 is greater than that of the two end sections, and the width of the guide groove 403 decreases from the middle section to the two end sections with a constant slope. A squeezing column 5 is slidably arranged in the guide groove 403. The diameter of the squeezing column 5 is the same as the width of the middle section of the guide groove 403. A second traction component is provided between the squeezing column 5 and the pressure handle 201.

[0045] The first clamp 401 and the second clamp 402 are made of medical-grade platinum-cured silicone rubber, which can undergo 10% to 15% controllable radial deformation. Initially, they are arc-shaped structures adapted to the intestinal tract. After they are attached, they form a complete clamping surface. The extension of the first clamp 401 is tightly fitted with the reset shaft 302a through a shaft hole. The second clamp 402 is rotatably connected to the connecting groove 401a of the first clamp 401 through a connector 402a, and the whole moves synchronously with the reset shaft 302a. Through the controllable deformation characteristics of the flexible material, it fits the intestinal tract with thickened periintestinal fat or edematous dilation, greatly increasing the contact area with the tissue, avoiding local pressure concentration, and without rigid compression during deformation, reducing the risk of rectal wall ischemia and tearing, while avoiding the risk of tumor dissemination caused by rigid contact. The flexible material can adapt slightly with intestinal peristalsis, reducing mechanical damage caused by repeated traction and alleviating postoperative inflammation.

[0046] The second traction assembly includes a buckle plate 7 and a second pull rope 6. A pull groove 101 is formed on the inner wall of the clamp body 1, and the buckle plate 7 is slidably installed within the pull groove 101. A second connector 8 is fixed to the top of the buckle plate 7, and the second pull rope 6 is connected between the second connector 8 and the two sets of extrusion columns 5. Connecting grooves 401a are provided on the top walls of both sides of the first clamp rod 401, and connecting pieces 402a are fixedly connected to the bottom walls of both sides of the second clamp rod 402. The connecting pieces 402a are rotatably connected to the connecting grooves 401a. A through hole is formed on one side of the second clamp rod 402, through which the second pull rope 6 passes and connects to the second connector 8. The through hole provides a passage for the second pull rope 6, ensuring that the pull rope can transmit tension along the length of the clamp rod, driving the extrusion columns 5 to slide. Both ends of the through hole have rounded chamfers to avoid the risk of breakage caused by friction between the pull rope and the hole opening, extending the service life of the pull rope. The through hole can restrict the position of the pull rope, preventing it from being squeezed by the intestinal tube during the opening and closing of the clamp head 4, ensuring smooth operation.

[0047] The connecting groove 401a and the connector 402a cooperate to realize the rotational connection between the first clamping rod 401 and the second clamping rod 402, providing room for the "outward micro-expansion" of the two clamping rods under the action of the squeezing column 5, ensuring that the clamping rods can smoothly form an elliptical clamping surface; and can limit the relative displacement direction of the two clamping rods to rotate only along the convex axis, avoiding clamping failure due to clamping rod misalignment, and ensuring gripping stability.

[0048] The guide groove 403 provides a precise sliding path for the compression column 5, preventing the compression column from deviating; the gradient structure, which is wide in the middle and narrow at both ends, allows the compression column 5 to form a uniform squeezing force with the groove wall when it slides to the narrow section, driving the flexible forceps to expand slightly outward, accurately adapting to edematous intestinal segments of different diameters; the smooth groove wall reduces the sliding resistance of the compression column 5, ensuring that doctors can easily control the deformation of the forceps through the buckle plate 7.

[0049] The squeezing column 5 acts as the driving component for the deformation of the clamp bar. When it slides along the guide groove 403, it squeezes the groove wall, converting the tension into the radial expansion force of the clamp bar, so that the clamp head 4 changes from the initial arc shape to a near-elliptical shape, which is suitable for the scenario of thick periintestinal fat.

[0050] The diameter of the squeezing column 5 is adapted to the middle wide section of the guide groove 403, ensuring that the clamp bar does not undergo additional deformation when sliding to the middle section. It can be used for regular intestinal clamping, realizing multiple uses of one clamp.

[0051] Working principle: The doctor checks the connection status of each component, pushes the buckle plate 7 to slide along the pull groove 101, confirms that the compression column 5 can move smoothly along the guide groove 403, and presets the initial position of the compression column 5 according to the state of the intestinal tract.

[0052] The doctor holds the handle 2 and presses the pressure handle 201. The pressure handle 201 drives the first connector 203 to pull down the first pull rope 303. The first pull rope 303 pulls the sliding frame 302 to slide along the slide rail 301. The reset shaft 302a of the sliding frame 302 drives the first forceps 401 and the second forceps 402 to close, initially fitting the intestinal tube.

[0053] If there is thickened periintestinal fat or intestinal edema, the doctor pushes the buckle 7 to slide along the pull groove 101. The buckle 7 drives the second connector 8 to pull the second pull rope 6. The second pull rope 6 pulls the squeezing column 5 to slide along the guide groove 403 towards the front end of the clamp head 4. The squeezing column 5 enters the narrow section of the guide groove 403, squeezing the first clamp bar 401 and the second clamp bar 402 to expand slightly outward, forming an elliptical clamping surface, increasing the contact area, and stabilizing the clamping of the intestinal segment.

[0054] The doctor adjusts the instrument angle by holding the handle 2 and pulls the intestinal tract. The flexible clamp rod deforms slightly with the peristalsis of the intestinal tract to avoid excessive traction. The buffer spring 305 absorbs the traction resistance to prevent a sudden increase in clamping force, and the anti-slip texture 404 further prevents tissue slippage and ensures the stability of the surgical field.

[0055] After the procedure is completed, the doctor releases the pressure handle 201, the reset spring 202 drives the pressure handle 201 to automatically reset, the first pull rope 303 loosens, the buffer spring 305 pushes the sliding frame 302 back to its original position, and the forceps head 4 opens; the reverse push of the buckle plate 7 loosens the second pull rope 6, the squeezing column 5 returns to the middle section of the guide groove 403, the forceps bar returns to its initial arc shape, and the instrument is removed.

[0056] The flexible deformation of the first clamp 401 and the second clamp 402, along with the driving force of the squeezing column 5, effectively increases the contact area of ​​the clamp head 4. Combined with the anti-slip texture 404, it prevents the intestine from sliding, improves the stability of the surgical field exposure, and is suitable for scenarios with thickened periintestinal fat and edematous intestines.

[0057] The controllable deformation of the flexible clamping bar effectively reduces the clamping pressure, lower than that of traditional grippers, thus reducing the risk of rectal wall ischemia and tearing; the buffer spring 305, in conjunction with the flexible material, avoids mechanical damage from repeated traction, which is conducive to the patient's rapid recovery.

[0058] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
