Description

[0001] SURGICAL ASSISTANCE DEVICE WITH BLOOD SUCTION AND TISSUE SUPPORT MECHANISMS

[0002] TECHNICAL FIELD OF THE INVENTION

[0003] The present invention relates to the technical field of mechanics, biomedical engineering, medical technology, development of medical and surgical instruments and more specifically to surgical assistance technology since it provides a surgical assistance device with blood suction and tissue clamping mechanisms.

[0004] BACKGROUND OF THE INVENTION

[0005] Surgical assistance technologies have advanced remarkably in recent decades, aiming to improve the precision, efficiency, and safety of surgical procedures. One of the key developments in this field has been the integration of suction and clamping mechanisms into medical devices, which has revolutionized the way various surgical interventions are performed.

[0006] Since the mid-20th century, suction systems have been fundamental in surgery for maintaining a clean surgical field free of blood and other fluids. Early suction devices were simple hand pumps, but with technological advancements, more sophisticated electrical and electronic systems have been developed. These systems allow for more effective and controlled suction, which is crucial in procedures where visibility and cleanliness of the surgical field are essential for the success of the operation. In parallel, grasping mechanisms have evolved significantly. In the early stages of modern surgery, surgeons relied on manual forceps and sutures to manipulate and hold tissues. However, the increasing complexity of procedures and the need for greater precision have driven the development of automated and semi-automated devices.These devices allow for firm support of the skin and muscle, minimizing tissue damage and improving the surgeon's efficiency.

[0007] Combining suction and clamping in a single device represents a significant advancement in medical technology. These multifunctional devices not only optimize operating room space but also improve coordination and synchronization during surgery. Furthermore, by reducing the need for multiple instruments, these devices decrease the risk of contamination and increase the speed at which procedures can be performed.

[0008] A prior art search was conducted for surgical assistance devices with blood suction and tissue clamping mechanisms, where it was found that different ones have been developed, as mentioned in Chinese patent application number CN 110710998 (A), published on January 21, 2020, with the title "DISTRACTION AND FIXATION DEVICE FOR LIVER AND GALLBLADDER SURGERY," which describes a support and fixation device for hepatobiliary surgery, comprising an annular support, wherein a connecting block is fixed to the annular support, a support piece is fixed to the lower end of the connecting block, a movable support mechanism and a dirty fluid suction mechanism are arranged on the annular support, the movable support mechanism comprising a sliding block, an L-shaped adjustment bar, and an F-shaped support piece.A pin shaft is fixed vertically at the upper end of the sliding block, rotary holes are formed evenly on a long bar of the L-shaped adjusting bar along the length direction, and the fl-shaped support piece can rotate freely around a short bar.

[0009] Also found was a utility model document from China number CN 213217317 (U) published on May 18, 2021, entitled "FLAP SEPARATOR FOR BREAST GLAND SURGERY". This document describes a flap separator for breast gland surgery, comprising a fixation ring, a support rod, and a fixation block, where the bottom of the fixation ring is fixedly connected to the support rod, one side of the top of the fixation ring is movably connected to the fixation block, the bottom of the support rod is recessedly connected to a support cylinder, one side of the support cylinder is recessed and connected with an adjusting bolt, the bottom of the support cylinder is fixedly connected to a suction cup, and the bottom of the fixation block is fixedly connected to a clamping plate.The other side of the upper part of the fixation ring is permanently connected to a handle. The inner bottom of the fixation block is permanently connected to a fixation plate. A hole is provided in the fixation plate, allowing a rotating shaft to conveniently rotate internally. This causes a steel cable to wind around the surface of the rotating shaft, retracting it within the fixation block. A traction hook is then connected to the end of the steel cable. This device is suitable for traction of skin flaps in breast surgery and has broad prospects for future development.

[0010] As can be seen, the aforementioned documents do not describe how to solve the problem of its structure being able to extend or contract, so that it adjusts to the area where the surgical procedure is performed; nor do they show that the structure has protrusions distributed equidistantly and projecting from the internal surface of said structure towards the center of its circumference, where these protrusions have a rectangular prismatic shape, lack a front face and are hollow, this configuration allowing a clamping forceps to be housed in each protrusion, these clamping forceps are adjusted in depth according to the needs of the doctor performing the surgical procedure, and with this, once the tissue of the surgical area is held, the diameter of the structure of the device as well as the level of the clamping forceps can be adjusted, stretching the area of ​​the surgical procedure to give more working space to the doctor.

[0011] Another technical feature not evident in the previously cited documents is the absence of a duct located on the outer surface of the device structure, instead running along its inner circumference. Furthermore, the documents fail to describe the inner surface of the structure as having at least two suction ducts, positioned opposite each other, which are inserted into the structure and hermetically connected to the connecting duct. This connecting duct then connects to an external suction system, which generates suction to remove accumulated blood from the area where the surgical assistance device is placed. This system includes blood suction and clamping mechanisms, preventing the surgeon from losing visibility of the surgical area due to blood accumulation and ensuring a better surgical process.

[0015] Another object of the present invention is to provide a surgical assistance device with blood suction and tissue clamping mechanisms, which has protrusions distributed equidistantly and projecting from the inner surface of said structure towards the center of its circumference, where said protrusions have a rectangular prismatic shape, lack a front face and are hollow.

[0016] An additional object of the present invention is to provide a surgical assistance device with blood suction and tissue clamping mechanisms, having a clamping forceps housed in each projection, said forceps being adjusted in depth according to the need of the physician performing the surgical process.

[0053] With reference to the figures, the surgical assistance device with blood suction and tissue clamping mechanisms is made up of a structure (1) which exhibits a circular configuration with an annular morphology and a hollow interior; the structure (1) has at least two extendable sections (2) integrated into its surface, preferably arranged opposite each other; this configuration allows the diameter of said structure (1) to be increased or decreased, making the surgical assistance device of the present invention adaptable to the surgical area where it is to be used.

[0054] A connecting duct (3) is attached to the outer surface of the structure (1) and extends into the structure (1), running along its inner circumference. At least two suction ducts (4) are positioned on the inner surface of the structure (1), opposite each other. These ducts extend into the structure (1) and are hermetically sealed to the connecting duct (3). This configuration allows the connecting duct (3) to be connected to an external suction system (not shown). The suction generated by this system then extracts the blood that has accumulated in the area where the structure (1) is located from the surgical assistance device with blood suction and restraint mechanisms.Blood enters through the ends of the suction ducts (4) located on the inner surface of the structure (1) and exits through the connecting duct (3), reaching the external suction system (not illustrated). This prevents the surgeon from losing visibility of the surgical area due to blood accumulation, ensuring a better surgical procedure. The external suction system (not illustrated) is not part of the surgical assistance device with blood suction and restraint mechanisms that is the subject of this invention.

[0055] At least four projections (5) are located on the surface of the inner face of the structure (1), equidistantly spaced and projecting from the inner surface of said structure (1) towards the center of its circumference. These projections (5) are rectangular prisms, lack a front face, and are hollow, with their bottom formed by the surface of the structure (1) itself. On the upper perimeter of the exposed face of each projection (5), that is, the face facing the center of the circumference of the structure (1), at least three longitudinally arranged slots (6) of equal width are located. The two slots (6) at the ends are of equal length, while the central slot (6) is longer.

[0056] On the inner surface of each of the lateral walls of the protrusions (5), there is a guide (7) with two alternately stepped levels. These guides (7) are arranged opposite each other and have the same dimensions; this configuration allows a clamping forceps (8) to be positioned within each protrusion (5). The clamp is precisely positioned and its depth adjusted within the protrusions (5) according to the specific needs of the surgery. The stepped levels within the guides (7) act as reference and support points, allowing the clamping forceps (8) to be inserted and secured at different depths. This provides flexibility in the clamping forceps (8), ensuring correct and stable alignment according to surgical requirements.

[0057] The clamping pliers (8) consist of a rectangular prismatic body (9) at its rear, which matches the dimensions of the hollow projections (5) in which the clamping pliers (8) are housed. This configuration allows the clamping pliers (8) to be precisely integrated into the projections (5), ensuring a firm and stable grip. The body (9) of the clamping pliers (8) facilitates alignment and assembly, optimizing the functionality of the assembly.

[0058] Each clamping pliers (8) has a protrusion (10) that extends from each of the rounded side walls of its body (9). These protrusions (10) are aligned with each other and with the guides (7) located on the inner face of the projections (5). This configuration allows the protrusions (10) to engage with the guides (7) and move along them. The alignment of the protrusions (10) with the guides (7) is crucial to ensure the controlled and precise movement of the clamping pliers (8) within the projections (5), allowing each clamping pliers (8) to be placed in the required horizontal position.

[0059] A fixed section (11) of the clamp is integrated into the rectangular prismatic body (9) of each clamping clamp (8) and begins at the upper front of this body (9), spanning approximately one-third of the body's thickness (9). The structure of the fixed section (11) initially projects horizontally from the upper front of the body (9), extending forward; subsequently, from this horizontal projection, the fixed section (11) curves and extends vertically downwards with a thin, elongated structure, which culminates in a clamp tip (12) that projects towards the base of the body (9), remaining at the level of the lower front of said body (9); This configuration creates a rectangular cavity (22) between the body (9) and the thin structure of the fixed section (11).

[0060] A notch (13) is positioned longitudinally in the center of the front of the lower face of the body (9) of each clamping pliers (8). A groove (14) is positioned longitudinally in the center of the front of the upper face of the body (9) of each clamping pliers (8). This groove (14) is aligned with the notch (13) and has the same length. The groove (14) extends through the entire thickness of the body (9), connecting with the notch (13).

[0061] A sliding button (15) is placed over the slot (14) and, on its underside, has a stem (23) that runs through the inside of the body (9) and protrudes through the notch (13).

[0062] The slot (14) is aligned with the slot (6) which is in the center of the upper perimeter of the exposed face of each projection (5), such that when the body (9) of any clamping pliers (8) is fully inserted into a projection (5), the sliding button (15) is exposed thanks to the slot (6). A movable section (16) is placed on each clamping pliers (8); this movable section (16) is formed by a pliers tip (17) which, at its upper part, has a support (18) of the same dimensions and shape as the notch (13), such that the pliers tip (17) is just below the body (9) of the clamping pliers (8). The support (18) is fixedly attached to the stem (23) of the sliding button (15). This configuration allows the movable section to slide along the notch (13) when the sliding button (15) is moved along the groove (14).

[0063] A spring (19) is placed inside the notch (13) between the support (18) and the end of the notch (13). This configuration ensures the return of the movable section (16) to the front of the body (9), allowing the clamping pliers (8) to remain in the closed position constantly, and thus clamp the fabrics between the clamp tips (12) and (17) of the clamping pliers (8).

[0064] The inner faces of the clamp tips (12) and (17), i.e., those that are in continuous contact, have a groove (20) that allows for improved gripping of the fabric.

[0065] Two protrusions (21) are fixed to the front of the upper face of the body (9) of each clamping forceps (8), arranged one on each side of the groove (14) and aligned with the grooves (6) at the ends of the upper perimeter of the exposed face of each projection (5), such that when the body (9) of any clamping forceps (8) is fully inserted into a projection (5), the protrusions (21) are exposed by the grooves (6). The protrusions (21) are preferably rounded and configured to assist in extracting the clamping forceps (8) from the projection (5) when grasped by the fingers of the user of the surgical assistance device with blood suction and tissue clamping mechanisms that is the subject of the present invention.

[0066] PREFERRED EMBODIMENT OF THE INVENTION

[0067] Examples

[0068] The following examples illustrate a preferred way of carrying out the present invention, and should therefore not be considered as limiting it.

[0069] Example 1. Surgery using the surgical assistance device with blood suction and tissue clamping mechanisms.

[0070] Before surgery, a clamping forceps (8) is inserted into each protrusion (5), ensuring that the extensible sections (2) are contracted to have the structure of the surgical assistance device with blood suction and tissue clamping mechanisms, in order to have the smallest diameter of the structure.

[0071] The surgeon then makes an incision in the specific area where the operation will be performed. In abdominal surgery, this could be an incision in the abdomen. Next, retractors are used to open the incision and expose the surgical area. The extendable sections (2) are extended to match the diameter of the structure (1), making it larger than the area where the incision was made. Each grasping clamp (8) is grasped by its protrusions (21) and pulled out of its housing, then positioned to grasp the tissue in the surgical area.Subsequently, each clamping pliers (8) are opened by sliding the button (15) along the groove (14), allowing the movable section (16) to move through the notch (13) located on the underside of the clamping pliers body (9) (8), thus separating the pliers tip (17) from the tip (12) of the fixed section (11); then placing the fabric to be clamped in the center of both tips, i.e., in the rectangular cavity (22); Subsequently, pressure is released on the sliding button (15), so that the spring (19) causes the movable section (16) to return to its closed position, thus holding the tissue, to give the surgeon greater visibility. This procedure is performed with each of the forceps.

[0072] The suction ducts (4) are placed inside the incision, so that when blood begins to accumulate, the external suction system (not illustrated) is activated so that the blood enters through the ends of the suction ducts (4) located on the surface of the inner face of the structure (1) and exits through the connecting duct (3), until it reaches the external suction system (not illustrated); this prevents the surgeon from losing visibility of the surgical area due to the accumulation of blood, ensuring a better surgical process.

[0073] Once the process is finished, before beginning the corresponding sutures, the tissue held by the clamps (8) is released, performing the same opening procedure used to clamp the tissue; to finish with the corresponding suture. In view of what has been stated in this descriptive chapter, it is reiterated that the scope of the present invention shall not be limited by the particularly described modalities, and it is understood that variations may be made in several respects.
