Description

1 / 18 Descriptive Report of Invention Patent Multidirectional Traction Platform for Video Surgery Field of Invention

[0001] The present invention describes a multidirectional traction platform for performing video surgeries. The platform, positioned externally to the patient, comprises a mobile base with two rods, one vertical and one horizontal, which can be attached to a desired location, such as on the operating table. The horizontal rod is connected to the central articulated structure by means of an articulated arm. The central articulated structure comprises a central bar, at least one lateral bar, and at least one mobile support per bar. Each mobile support is positioned on one of the bars and allows the attachment of straight or curved hemostatic forceps.

[0002] The platform enables the elevation of the patient's abdominal wall by means of transparietal sutures fixed by hemostatic clamps on mobile supports, thus creating an intracavitary working space in the desired body region, allowing video surgeries to be performed without insufflation of the abdomen with CO2 and without interfering with the position and movements of the video surgery instruments introduced into the abdomen, which are necessary for the indicated surgical procedure.

[0003] In view of these considerations, the present invention falls within the fields of the surgical sector, specifically within the scope of medical devices intended for the traction of body tissues for the performance of surgical procedures. Background of the Invention

[0004] Video surgery encompasses surgical procedures that utilize imaging and illumination systems coupled to a specific instrument (endoscope or optics), which allows intracavitary visualization through small incisions. Additional surgical instruments are positioned from Petition 870260015443, dated 19 / 02 / 2026, page 16 / 51 2 / 18 intracavitary approach from reduced incisions, thus allowing the performance of low, medium and high complexity surgical interventions.

[0005] In this way, access lesions, tissue trauma, intraoperative hemorrhage (and consequent reduction in the need for hemotherapy), visceral manipulation, postoperative pain and discomfort are considerably reduced, among other advantages already well established in medicine for more than three decades and which are currently being proven in veterinary medicine.

[0006] Compared to conventional surgery, human patients undergoing video-assisted surgery demonstrate shorter hospital stays, quicker returns to work and physical activities, less intra-abdominal adhesion formation, and better aesthetic results. In companion animals, it has been shown that, in addition to some of the advantages mentioned, video-assisted surgery also allows for a reduction in the inflammatory response, a shorter postoperative ileus, and a faster return to food intake during the postoperative period.

[0007] For these reasons, in medicine, several procedures using video surgery are being converted into the gold standard modality for the treatment of multiple diseases, offering numerous advantages to the patient and the health system itself, optimizing available resources and reducing the need for hospitalization and postoperative care associated with the management of celiotomy wounds.

[0008] Video surgery encompasses different modalities, named according to the cavity or organ surgically accessed. Thoracic surgeries are called thoracoscopies or video-assisted thoracic surgeries (VATS). Abdominal surgeries, on the other hand, are known as laparoscopies, laparoscopic surgeries, or laparoscopy-assisted surgeries (also called video-assisted or hybrid surgeries) when they involve a conventional "open" surgical step. Other modalities include transluminal surgery through natural orifices (NOTES Petition 870260015443, dated 19 / 02 / 2026, page 17 / 51 3 / 18 Natural Orifice Transluminal Endoscopic Surgery (NUE) and single-incision laparoendoscopic surgery (LESS).

[0009] For laparoscopic surgeries, as well as for NOTES and LESS, it is necessary to create an intracavitary workspace that allows for the performance of dieresis, excision, and synthesis maneuvers. The universally used method for this purpose is abdominal insufflation with medical CO2, using electronic equipment (insufflators) that control the insufflation rate and intra-abdominal pressure (IOP). However, the establishment and maintenance of pneumoperitoneum with CO2 can cause hemodynamic and pulmonary complications, injuries to viscera and vessels from abdominal access instruments (Veress needle and first trocar), as well as produce clinically important neurohumoral responses.

[0010] Among the changes that may be associated with pneumoperitoneum are described reduction in cardiac output (CO), changes in cardiac preload, reduction in ejection fraction (EF), increased systemic vascular resistance (SVR), increased mean arterial pressure (MAP), cardiac arrhythmias, reduced hepatic blood flow, reduced splenic blood flow, reduced renal blood flow, changes in intracranial pressure, changes in intraocular pressure (IOP), reduced total lung volume, reduced functional residual capacity (FRC) of the lung, reduced pulmonary compliance, occurrence of atelectasis, hypercapnia and respiratory acidosis.

[0011] Such changes are usually transient and well tolerated in patients in whom pneumoperitoneum with CO2 up to 12 mmHg is used and with appropriate selection of the anesthetic protocol and anesthetic techniques. However, in certain patient categories, such as those with compromised cardiopulmonary condition, the elderly, obese, hepatopathic and nephropathic patients, pneumoperitoneum can cause serious consequences.

[0012] In view of the changes and possible complications associated with inflation Petition 870260015443, dated 19 / 02 / 2026, page 18 / 51 4 / 18 abdominal procedures classified as gasless have been developed, in which video surgeries are performed without establishing pneumoperitoneum, and consequently, without the need for CO2. In these surgeries, the working space is provided by mechanical retraction of the abdominal muscular wall through external traction. Procedures of this nature are also found in the literature under the name lift laparoscopy.

[0013] An important application of gasless surgery is for cases of diaphragmatic hernias treated by abdominal video-assisted surgery (laparoscopy) in pediatric human patients with congenital hernias or in adults with extensive hernias. Dogs and cats with congenital or acquired diaphragmatic hernias can also benefit from this type of approach. However, video-assisted reconstruction of diaphragmatic hernias via abdominal access requires considerable working space for the application of prosthetic implants (meshes) and / or intracorporeal sutures.

[0014] In these patients, if pneumoperitoneum is established with medical CO2, deleterious effects tend to occur, since when the gas is insufflated into the abdomen it naturally reaches the thoracic cavity and causes pneumothorax or hypertensive pneumomediastinum. To minimize (but not suppress) such effects, low pneumoperitoneum pressures (with consequent pneumothorax or pneumomediastinum) ranging between 4 and 6 mmHg are indicated, which can make reconstructions of extensive or chronic diaphragmatic defects very difficult, or even impossible, especially if the therapeutic methodology involves the application of intracorporeal sutures.

[0015] There are various patent documents for devices and equipment for performing gasless surgery, such as, for example, documents US00531802A, US20080234551A1, US005398671A, US005501653A, US005514075A, US005573495A, US005976079A, US005716327A, US20040097792A1 and GB2495522. Petition 870260015443, dated 19 / 02 / 2026, page 19 / 51 5 / 18

[0016] Many of the devices developed for gasless surgery in humans are not suitable for animals due to the obvious anatomical differences between species. On the other hand, for their own application in humans, gasless devices tend to have limitations regarding the possibilities of precise adjustment to the different body conformations of each patient and to the different anatomical spaces to be addressed, according to the different surgeries indicated.

[0017] There are scientific publications involving humans that describe the application of Kirschner wires through the muscle wall, placed transversely to the midline and supported by a system of external chains. In the case of dogs and cats (which have much longer abdomens and rib cages), especially those with reduced body size and abdominal cavity (in cases involving small breeds and puppies), this type of technique seems to have little (or no) possibility of application. Otherwise, traction of this nature would cause greater tissue trauma than that obtained from the simultaneous application of several transparietal sutures for elevation of the wall, as described in the present invention.

[0018] Several industrial designs for external instruments for abdominal wall traction placed inside the abdomen via surgical access (celiotomy) have also been published, such as in documents US005398671A, US005501653A, US005514075A, US005573495A, US005976079A or US005716327A. In these cases, it becomes necessary to create a surgical wound connecting the skin and abdomen, which needs to be occluded at the end of the procedure. This access constitutes additional tissue trauma to the patient if performed solely for the positioning of the traction instrument.

[0019] Other patents with potential use in humans and animals propose the application of gasless devices that expand after being placed inside the cavity (US20040097792A1, GB2495522). As Petition 870260015443, dated 19 / 02 / 2026, page 20 / 51 6 / 18 disadvantage in relation to the present invention is that visceral compression is expected to occur with the creation of the working space. The very conformation of the devices in these documents would make it difficult to apply intracorporeal sutures in the case of surgery on dogs with extensive diaphragmatic hernias.

[0020] Although various equipment and devices exist in the present state of the art, as well as surgical techniques for performing gasless surgery, this surgical modality has been little explored worldwide in human patients and is in its initial stages in relation to veterinary surgery. Therefore, the development of new equipment, devices, platforms and instruments, such as those that may incorporate the knowledge disclosed in the present invention, is justified, to facilitate its application in different surgical techniques. Summary of the Invention

[0021] Thus, the present invention solves problems of the prior art by providing a multidirectional traction platform for gasless video surgery comprising a mobile base, a central articulated structure and articulated arms, the present platform being very versatile in terms of adjusting the elevation of the muscle wall in different directions, angles and heights, according to the patient's anatomy and the surgical procedure to be performed. It also allows easy adjustment of abdominal traction during surgery, as needed.

[0022] Unlike the present state of the art, the invention in question makes it possible to suspend the muscle wall by transparietal sutures with needle-like threads routinely used in conventional surgery, from a multidirectional traction platform, causing minimal tissue damage without the need to make an incision to allow access and positioning of intracavitary traction devices.

[0023] In a first object, the present invention describes a platform Petition 870260015443, dated 19 / 02 / 2026, page 21 / 51 7 / 18 multidirectional traction for gasless video surgery comprising means of traction of a patient's abdominal wall (19) by means of transparietal sutures.

[0024] These and other objects of the invention will be immediately appreciated by those skilled in the art and will be described in detail below. Description of the Figures

Detailed Description of the Invention Petition 870260015443, dated 19 / 02 / 2026, page 22 / 51 8 / 18

[0033] The descriptions that follow are given by way of example and are not limiting to the scope of the invention and will make clearer the subject matter of this patent application.

[0034] In a first embodiment, the present invention describes a multidirectional traction platform for gasless video surgery comprising means of traction of the abdominal wall of a patient (19) by means of transparietal sutures. In one embodiment, each suture comprises at least one suture thread (20) associated with at least one hemostatic clamp (18) and at least one needle, each suture thread (20) being associated with the patient's abdominal wall (19), passing through it.

[0035] In one embodiment, the multidirectional traction platform for gasless video surgery comprises at least one mobile base (A), a central articulated structure (B) and an articulated arm (5), wherein the mobile base (A) is associated with the central articulated structure (B) by means of the articulated arm (5).

[0036] In one embodiment, the movable base (A) comprises at least one fixing clamp (1), at least one vertical cylindrical rod (2), at least one connecting piece (3) and at least one horizontal cylindrical rod (4), wherein the vertical cylindrical rod (2) and the horizontal cylindrical rod (4) are connected to the connecting piece (3) by means of gripping clamps, allowing adjustment of the position of the rods (2) and (4).

[0037] In one embodiment, the central articulated structure (B) comprises at least one central bar (7), one lateral bar (8) and one movable support (C) per bar, wherein the central bar (7) is associated with the lateral bars (8) by means of an articulated structure (9) and the central (7) and lateral (8) bars comprise means of associating the movable supports (C).

[0038] In one embodiment, each mobile support (C) comprises a main segment (11) for coupling a straight or curved hemostatic clamp (18).

[0039] In one embodiment, the central bar (7) and the side bars (8) of Petition 870260015443, dated 19 / 02 / 2026, p. 23 / 51 9 / 18 central articulated structure (B) comprising equally spaced transverse holes throughout its length.

[0040] In one embodiment, each movable support (C) comprises at least one opening (13) in its interior in the shape of an inverted pyramid communicating with the outer face of the movable support (C) from a fenestration (14), of uniform width throughout its length. In a preferred embodiment, each movable support (C) has exactly one opening (13) in its interior.

[0041] In one embodiment, each movable support (C) comprises at least one secondary segment (12) with a tunnel-shaped opening (15) externally attachable to the central (7) and lateral (8) bars, allowing the movable support (C) to slide along the bars (7) and (8), and with holes (17) in its upper and lower part that connect to the holes in the central (7) and lateral (8) bars, by means of a pass-through (16), fixing the movable supports (C) to the central articulated structure (B). In a preferred embodiment, each movable support (C) comprises exactly one secondary segment (12).

[0042] In one embodiment, the articulated arm (5) comprises joints (6) in its central region and at its ends, the articulated arm (5) being associated with the movable base (A) by means of a joint at one end.

[0043] In one embodiment, the articulated arm (5) is associated with the central bar (7) of the central articulated structure (B) by means of a joint (6) at the end opposite to the end of the articulated arm (5) associated with the movable base (A).

[0044] In one embodiment, the present invention has features that allow its use in various gas / ess surgeries of small animals (dogs and cats), including its application in the treatment of diaphragmatic hernias and considering all the problems of using CO2 pneumoperitoneum in this type of patient (19), as previously explained. In one embodiment, the present invention is not limited exclusively to use in small animals, Petition 870260015443, dated 19 / 02 / 2026, page 24 / 51 10 / 18 because it is fully adaptable to different individual body and anatomical conditions, which gives it potential for use in gasless video surgery in humans and in different animal species in veterinary surgery.

[0045] In one embodiment, the present multidirectional traction platform for gasless video surgery comprises three main elements, as described below:

[0046] The first element comprises a movable base (A) with a fixing clamp (1), a connecting piece (3) with gripping clamps, two rods, one vertical (2) and the other horizontal (4). In one embodiment, the rods are articulated by two gripping clamps joined in a single connecting piece (3) and an articulated arm (5) with joints (6) at its ends.

[0047] In one embodiment, the vertical rod (2) is associated with a fixing clamp (1) at its base, which allows the platform to be fixed to the surgical table. In one embodiment, the vertical rod (2) allows the horizontal rod (4) to move about its axis - 360° rotation and height and depth adjustments - thanks to the two gripping clamps that articulate both rods. These two gripping clamps are joined together by their corresponding bases at a 90° angle and form a single piece, the joining piece (3).

[0048] In one embodiment, the horizontal rod (4) has a 90° curved end which is fixed at its central point to an articulated arm (5). This articulated arm (5) has a joint (6) at each end and a central thread to fix its position. The articulated arm (5) is firmly fixed to the horizontal rod (4) by one of its joints.

[0049] The second element comprises an articulated structure formed by three bars, one central (7) and two lateral (8).

[0050] In one embodiment, the bars are connected by a hinged structure (9), which allows their movement, with the central bar (7) being the longest of the three. In one embodiment, the side bars (8) have similar lengths. Both the central bar (7) and the side bars (8) have Petition 870260015443, dated 19 / 02 / 2026, page 25 / 51 11 / 18 various supports (C) for hemostatic forceps (18) coupled.

[0051] The third element comprises at least one movable support (C) for the hemostatic forceps (18). Each support for the hemostatic forceps (18) is designed to accommodate a forceps of this type inside and to be able to be fixed and moved in the different parts that form the articulated structure, assuming different positions, according to the need. In one embodiment, each support has two joined and indivisible segments, described here as main and secondary for ease of understanding.

[0052] In one embodiment, the main segment (11) of the support has an inverted pyramidal shape (with the base shorter). It has an opening (13) inside, also pyramidal in shape, to accommodate a straight or curved hemostatic forceps (18). This opening (13) communicates with the outer face of the piece through a fenestration (14), which extends along its entire height. This fenestration (14) has a uniform width, sufficient for the passage of the tip of a curved or straight hemostatic forceps (18) for routine use, such as Halsted (mosquito), Halsted-Hartmann, Kelly and Crile forceps, among others.

[0053] In one embodiment, this main segment (11) of the support allows the hemostatic forceps (18) to be attached, with the tip of the forceps (18) at the bottom and the rings at the top, for subsequent fixation of the traction suture of the patient's abdomen (19). The internal space for fitting the forceps (18) is wide enough so that the tip of the forceps (18) can be opened, allowing the suture thread (20) to be fixed once that instrument is already inside the piece.

[0054] In one embodiment, the secondary segment of the support has an opening (15) to be coupled to the central articulated structure (B), allowing the sliding of the mobile support (C) along the structure according to the need for direction of the traction suture. In one embodiment, at its midpoint, this segment has a hole (17) to position a pass-through (16), which passes through one of the holes in the articulated structure. Petition 870260015443, dated 19 / 02 / 2026, page 26 / 51 12 / 18 to ensure its fixation.

[0055] In one embodiment, the present invention is easily adjustable to different types and configurations of surgical tables, both those used in human surgery and those employed in veterinary surgery, and can be fixed in different positions according to the surgery to be performed.

[0056] In one embodiment, the height and depth adjustment, as well as the rotation, of the horizontal rod (4) in relation to the vertical rod (2) is performed on the mobile base (A). Similarly, the horizontal rod (4) can also be rotated individually on its own axis. The curved end of the horizontal rod (4) is connected to the central articulated structure (B) by means of an articulated arm (5) with joints (6) at its ends, which allows its fixation with a central screw. All these features of the mobile base (A) provide ample movement possibilities to position the central articulated structure (B) at a desired point according to the patient's position (19), location of the surgical access, position of the surgical team, and positioning of the instruments and video surgery equipment.

[0057] In one embodiment, due to its articulated parts and rods with adjustable positions, the present invention is very versatile, allowing the muscle wall elevation to be adjusted in different directions, angles and heights. It also allows for proper adjustment to the specific anatomy of each patient (19) and each body region to be operated on.

[0058] Its designation “multidirectional” is also due to the concept of enabling the direction and sense of the external traction sutures that raise the patient’s muscle wall (19) not to interfere with the movements of the operating instruments (optics, cannulas / trocars, forceps, scissors, needle holders, staplers and clips). This condition makes it possible for video surgery to be performed with the same principles applied to surgeries performed with abdominal distension by pneumoperitoneum, but without the deleterious effects thereof.

[0059] Supporting the muscular wall using transparetic sutures with threads Petition 870260015443, dated 19 / 02 / 2026, page 27 / 51 The 13 / 18 needles routinely used in conventional surgery cause little tissue damage and eliminate the need to perform a celiotomy to position intracavitary traction devices. Thus, the absence of an intra-abdominal device allows for ample working space within the cavity and facilitates the execution of video surgery maneuvers, including the application of sutures, staples, and clips.

[0060] In one embodiment, the supports for accommodating the hemostatic forceps (18) of the present invention allow the fixation of multiple traction sutures at different points on the patient's abdomen (19) simultaneously. For this purpose, conventional hemostatic forceps (18) of different types and sizes can be used. Furthermore, each support can assume different positions on the central articulated structure (B) of the platform, being able to slide through the central (7) and lateral (8) bars of the structure and be fixed at different points, according to the orientation desired for each of the traction sutures.

[0061] In one embodiment, the support for the hemostatic forceps (18) has a unique design that allows the passage of straight or curved forceps (18) (whichever the surgeon chooses to use on his instrument table) through its interior, thanks to the central fenestration (14) with a width designed for this purpose. Inside the piece, the forceps (18) can be opened and closed to adjust the tension of the thread that pulls the patient's muscle wall (19) as many times as necessary.

[0062] Thus, if desired, a portion of the total abdominal area that needs to be suspended can be kept elevated while another portion can remain relaxed, reducing tissue traction. This feature is not achieved when performing some of the state-of-the-art gasless surgeries, in which the muscle wall is supported by a single articulated device introduced into the abdomen. This feature tends to reduce pain stimulus by reducing the traction imposed on the muscle wall.

[0063] In one embodiment, the movement of the articulated arm (5) that Petition 870260015443, dated 19 / 02 / 2026, page 28 / 51 14 / 18 connects the horizontal rod (4) with the central articulated structure (B), the movement of the support for the hemostatic clamps (18), the adjustment of the articulated structures. (9) existing between the bars (7) and (8) that form the central structure (B) and the possibility of adjusting the traction sutures fixed by the hemostatic clamps (18), allow the direction of the traction force of each of the sutures to be adjusted at any time during the surgery. This versatility allows the elevation of the muscle wall to be adjusted according to the need for more or less working space, depending on the procedure performed and the stage of the surgery.

[0064] With this platform, by having several points of support for the wall from the traction sutures, the tensions on each suture point are reduced and the amplitude of the work area created is greater than that obtained by elevating a single region of the muscle wall. It is assumed that the lower the tension on a support point, the lower the painful stimulus at that point and the tissue ischemia due to compression.

[0065] After using the present invention, the suture threads (20) are cut and removed from the patient (19) without the need to suture the muscle wall or apply dressings to the transparietal traction suture passage sites, configuring itself as a minimally invasive alternative for abdominal wall elevation during gasless surgeries. Example 1 - Multidirectional Traction Platform

[0066] The examples shown here are intended only to demonstrate one of the numerous ways of carrying out the invention, however without limiting its scope.

[0067] For illustrative purposes, the mobile base (A) comprises two cylindrical rods, one vertical (2) and the other horizontal (4), a fixing clamp (1) for fixing to the surgical table, two gripping clamps joined in a single connecting piece (3) for simultaneous fixing of the two rods (2) and (4) and an articulated arm (5) with ball joints (6) at its ends. Petition 870260015443, dated 19 / 02 / 2026, page 29 / 51 15 / 18

[0068] A fixing clamp (1) is firmly attached to the vertical rod (2) and allows the multidirectional traction platform to be fixed to the surgical table for gasless video surgery. The two gripping clamps mounted on the connecting piece (3) allow the horizontal rod (4) to assume any position relative to the central axis of the vertical rod (2). Similarly, the horizontal rod (4) can be adjusted in height and depth relative to the vertical rod (2). The horizontal rod (4) has a 90° angle bend at one end. The horizontal rod (4) can also rotate its position relative to its own axis.

[0069] The articulated arm (5) has great mobility thanks to the joints (6) at each end and its central joint. This arm (5) has a central screw that allows it to be fixed once the position of the central articulated structure (B) has been adjusted. The articulated arm (5) is fixed to the central bar (7) of the central articulated structure (B) by means of one of its joints.

[0070] The vertical (2) and horizontal (4) cylindrical rods can be made from different materials, diameters and lengths according to the dimensions of the patients who will undergo gasless surgery. Similarly, the articulated arm (5), the fixing clamp (1) and the connecting piece (3) can be made from different materials, shapes and dimensions.

[0071] Figure 2 shows a general perspective of an example embodiment of the central articulated structure (B) of the traction platform. This element comprises a set of bars, one central (7) and two lateral (8).

[0072] The central bar (7) has a length slightly greater than the sum of the two side bars (8), being articulated to each of the side bars (8) by a ball-type articulated structure (9). One or more movable supports (C) for hemostatic forceps (18) are attached to the central bar (7) on each side of the central point of attachment to the articulated arm (5).

[0073] The side bars (8) of the central articulated structure (B) of the platform Petition 870260015443, dated 19 / 02 / 2026, page 30 / 51 16 / 18 have similar lengths. Each side bar (8) has attached one or more movable supports (C) for hemostatic forceps (18). At their free ends, the bars have plates (10) fixed to the bar to prevent the supports (C) for hemostatic forceps (18) from falling.

[0074] The central (7) and lateral (8) bars of the central articulated structure (B) have holes at symmetrical transverse distances along their entire length to allow temporary attachment of the mobile supports (C) for the hemostatic forceps (18) by means of a central pass-through (16).

[0075] The central (7) and lateral (8) bars of the central articulated structure (B) can be made from different materials, lengths and shapes according to the dimensions of the patients who will undergo gasless surgery. They can even be developed in the form of a cylindrical bar, by adjusting the design of the mobile supports (C) for the hemostatic forceps (18).

[0076] Figures 3, 4 and 5 show general perspectives of an embodiment of the mobile support (C) of the present invention. This element comprises a support piece for hemostatic forceps (18) used in fixing transparietal sutures applied in the elevation of the patient's muscle wall (19) and creating a workspace for gasless surgeries.

[0077] Figure 3 shows the movable support (C) of the traction platform from a rear view. Each movable support (C) has two joined segments, described in this diagram as the main segment (11) and the secondary segment (12).

[0078] The main segment (11) of the mobile support (C) has an opening (13) inside (Figure 4) to accommodate a straight or curved hemostatic forceps (18) (Figure 5). This opening (13) follows the inverted pyramidal design of the piece and allows the hemostatic forceps (18) to be opened inside. This opening (13) communicates with the external face of the piece through a fenestration (14), of uniform width throughout its length, allowing the Petition 870260015443, dated 19 / 02 / 2026, page 31 / 51 17 / 18 passage of straight and curved hemostatic forceps (18), without them falling off the specimen.

[0079] The secondary segment (12) has a wide tunnel-shaped opening (15) fitted to be coupled externally to the shaft of the bar, and can be slid around it.

[0080] Figure 4 shows a side view of the mobile support (C). This perspective also shows the tunnel-shaped opening (15) through which the support is positioned on the central articulated structure (B) of the platform. To fix the support at a specific point on the bars that make up the central articulated structure (B), the pass-through (16) is placed through the holes (17) in the upper and lower parts of the piece, which correspond to the holes in the central (7) and side (8) bars. The length of the pass-through (16) allows its complete exposure through the bar and the support piece itself for the hemostatic forceps (18).

[0081] Figure 5 shows the mobile support (C) from a rear view, already positioned on the central articulated structure (B) of the platform and with a hemostatic clamp (18) placed inside it. The hemostatic clamp (18) is placed inside the mobile support (C), with the tip at the bottom and the rings at the top. The interior space for fitting the clamp (18) is wide enough so that its tip can be easily opened and closed, allowing adjustment of tension and securing the transparetic suture applied to the patient (19).

[0082] During traction of the transparietal suture, the clamp (18) is positioned on the posterior part of the central (7) and lateral (8) bars of the central articulated structure (B) of the platform, as shown in Figure 6. The tension of the thread allows the clamp (18) to remain firmly in place within the movable support (C).

[0083] The mobile supports (C) for hemostatic forceps (18) can be manufactured in different materials and sizes, although it is necessary that the internal space of the piece accommodates a hemostatic forceps (18) and allows its Petition 870260015443, dated 19 / 02 / 2026, page 32 / 51 1 / 1 opening and closing.

[0084] Figure 6 shows an overview of the multidirectional traction platform for gasless video surgery composed of all its previously described elements (A, B and C). In this figure, one can observe the fixation clamp (1) for fixation to the surgical table, the vertical cylindrical rod (2), the horizontal cylindrical rod (4), the two gripping clamps of the connecting piece (3), the articulated arm (5) with articulations (6) at its ends, the central bar (7) and the two lateral bars (8) of the central articulated structure (B), the mobile supports (C) for the hemostatic clamps (18) and the hemostatic clamps (18) inside. Note that the hemostatic clamps (18) are positioned behind the central (7) and lateral (8) bars of the central articulated structure (B).

[0085] Figure 7 schematizes an overview of the traction platform during its use for traction of the muscular wall of a patient (19) in performing gasless video surgery. Traction is exerted by suture threads (20) applied transparetically directly to the patient (19) and fixed by means of hemostatic clamps (18) placed inside the mobile supports (C).
